Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for automatically cleaning a bolster of a forging press.

[0002]

[Prior art]

 During the forging press, especially hot or warm forging press work, the scale scatters from the surface of the heated work, and a lubricant such as graphite water added to the mold during molding is also added to the die inside the press. It cannot be easily removed because it is deposited and fixed on the space, especially on the upper surface of the bolster and the side frame surface. If this is left as it is, the surface of the bolster cannot be maintained at an accurate level due to the adhered matter, and when the lower die holder is attached, it will rattle and rattling. Is being removed by.

Recently, a die holder exchange system, so-called Q.D. D. Although the C device has been developed and is widely used in the industry, the die replacement is completed within a very short time by loading and unloading the die holder, which greatly contributes to the improvement of workability. In contrast to this, there was a problem that cleaning the surface of the die space within this short period of time was a labor-intensive and inefficient task as before.

In order to solve this problem, some proposals have been already made. For example, in the invention of Japanese Utility Model Laid-Open No. 3-42338, as shown in FIG. 5, a vertically movable front shutter 101 that opens and closes a die space is provided with high-pressure water and air injection nozzles 102 that are directed into the space. A structure is proposed in which the die space is washed from the spray nozzle in conjunction with the vertical movement of the front shutter.

[0005] In addition, the idea of Fukukaihei 3-91135, in which the jet nozzle is retractably stored in the bed hard plate and the washing water is jetted upright only when the lower die holder is removed, a jet that moves up and down There are many such devices, including the invention of No. 3-42337, which uses a control valve for the nozzle.

[0006]

[Problems to be solved by the device]

 All of the conventional techniques shown here were developed with the aim of replacing the washing of bolsters, which used to rely on human labor, with an automated device, and in that sense it can be evaluated that some effects were exhibited. . However, it is well known empirically that in many cases, if the scale or lubricant that scatters during hot forging sticks to the bolster surface, it cannot be completely removed by simply injecting high-pressure water or compressed air. It Even if the surface of the bolster was conventionally washed manually, it cannot be removed by simply injecting compressed air or high-pressure water from the tip of the air hose, and the operator rubs a wire brush etc. onto the surface to force it to harden. The kimono had to be peeled off. The biggest problem was that this work was inefficient, heavy labor in a narrow space, and dangerous work, so it is said that simply automating the cleaning with the injection nozzle is not enough to solve the problem. It's difficult.

An object of the present invention is to solve the above-mentioned problems, to truly free the operator from complicated cleaning work, and to provide a highly efficient automated bolster cleaning device for a forging press.

[0008]

[Means for Solving the Problems]

 A bolster cleaning device for a forging press according to the present invention comprises a frame 1 which is inserted into a die space of the forging press so as to be able to move back and forth, and a front-rear moving frame 2 which is slidably supported along a side surface 11 in the frame. A cleaning head including a left and right moving base 3 slidably supported along the bottom surface 21 of the front and rear moving frame 2, and a rotating brush 41 and an ejection nozzle 42 suspended from the left and right moving base 3 so as to be vertically movable. 4 and a drive mechanism for driving the movement of each of the movable parts in a timely manner to solve the above-mentioned problem.

More specifically, in addition to the above-described structure, a large number of injection nozzles 13 are provided on the outer surface 12 of the frame 1 facing the side frame of the press, which is a mode in which the problem of the invention can be effectively solved. Further, a preferable embodiment is a structure in which a mounting surface 14 that can be clamped to the slide S of the forging press is attached to the upper end of the frame 1 and traveling wheels 15 adapted to a rail pitch for exchanging the die holder are attached to the lower end.

[0010]

[Action]

 When one molding lot is completed and the die holder is taken out from the die space of the forging press, the frame 1 of the device of the present invention is inserted into the space created there. FIG. 3 is a schematic plan view showing the operation of the cleaning device of the present invention, and FIG. 1 is a perspective view of the embodiment. In both figures, the cleaning head 4 is suspended in the frame 1 via the front-rear moving frame 2 and the left-right moving table 3, but first, the front-rear moving frame 2 and the left-right moving table 3 are driven to wash the cleaning head 4. Move to a convenient location. For example, as shown in FIG. 3, the rotary brush 41 is positioned at the left corner of the front surface of the forging press, the rotary brush 41 is lowered, and the brush surface is pressed against the surface of the bolster B. In this state, the left and right moving table 3 is driven to move the rotary brush 41 rightward while rotating the rotary brush 41 along the front end portion. Simultaneously with the cleaning operation of the rotary brush 41, or independently according to the contamination state of the surface, a fluid for cleaning from the injection nozzle 42, such as high-pressure water, compressed air, hot water, high-pressure steam, or another appropriately selected medium is applied to the surface. To jet. When the rotating brush 41 reaches the right corner while cleaning, it temporarily stops, and here the front-rear moving frame 2 moves and moves backward by the width of the rotating brush 41, and this time the left and right moving base 3 moves toward the left. Thus, the cleaning operation of the rotating brush 41 proceeds. In this way, if the drive control in which the timings of the left-right moving base 3 and the front-rear moving frame 2 are appropriately combined is incorporated in advance, the cleaning work by the cooperation of the rotating brush 41 and the injection nozzle 42 automatically proceeds, and the bolster B The entire cleaning of the house will be fully carried out without the need for human assistance.

【Example】

 FIG. 1 is a perspective view showing an embodiment of the present invention, and FIGS. 2A, 2B, and 2C are three views of the same embodiment. The present invention relates to a device for cleaning a bolster of a forging press, and is not limited to the form of the die space, but in recent years, a die holder exchange device that has been rapidly generalized, so-called Q. D. Since a forging press equipped with a C device occupies the mainstream, an example applied to this model will be shown. The frame 1 of the apparatus comprises a rectangular box, and traveling wheels 15 are provided at the bottom of the box. The wheel pitch is the same as the rail for exchanging the die holder, and after one lot of forging is completed, it is directly loaded into the die space where the die holder has been unloaded. In this case, it goes without saying that the rotating brush 41 is located above so as not to interfere with the bolster surface when the frame enters. The frame 1 fitted into the die space can be easily mounted with the mounting surface 14 provided at the upper end thereof by the slide S and the clamper C of the forging press in the same manner as the upper die holder is mounted. 1 is suspended in the hollow as shown by the solid line in FIG.

The front-rear moving frame 2 that can slide along the inner surface 11 A of the frame 1 is horizontally suspended by two front-rear guides 22 that are horizontally laid horizontally in parallel with the side surfaces. It has a central screwing portion 24 in which a female screw to be screwed with a central forward-backward moving screw 23 which is laterally installed in parallel is engraved. Therefore, when the forward / backward moving motor 25 attached to the frame outer surface 12A rotates, the forward / backward moving screw 23 rotates, and the forward / backward moving frame 2 moves together with the screwing portion 24 screwed with the screw. Move horizontally along.

The left and right moving base 3 is supported by two left and right guides 31 along the bottom surface 21 of the front and rear moving frame 2 so as to be slidable horizontally and horizontally. Both ends of the two left and right guides 31 are fixed to the left and right moving block 32 near the left and right inner side surfaces 11B, and the left and right moving blocks 32 are two moving block guides protruding horizontally and in parallel on the inner side surface 11B. It is sandwiched between 33 and supported horizontally. A female screw penetrating in parallel with the inner side surface 11B is threaded on the left and right moving block 32, and two left and right moving screws 34, which are screwed into the female screw, are horizontally mounted in parallel with the inner side surface 11B. Both ends of the two left and right moving screws 34 penetrate the side wall of the frame 1, and the two chain wheels 35 attached to one outer surface 12B are fixed. Since the chain wheel 35 is rotated by the rotation of the left / right moving motor 37 via the roller chain 36, the left / right moving block 32, the left / right guide 31, and the left / right moving base are rotated by the rotation of the left / right moving screw 34 by the motor drive. 3 and 1 move in the left-right direction integrally.

The left and right moving base 3 has a cleaning head 4 which is vertically hung on the bottom thereof and which is composed of an elevating cylinder 43, a rotating brush 41, an injection nozzle 42, and a rotation motor 44. After the rotary brush 41 reaches the upper part of the predetermined position, the lifting cylinder 43 is operated to press the rotary brush 41 against the surface of the bolster B, and if necessary, a cleaning fluid such as high-pressure water is supplied from the injection nozzle 42. While injecting compressed air, the rotation motor 44 of the rotary brush 41 is operated to rotate the rotary brush 41 and move it left and right. If the fluid to be ejected is piped independently from the supply unit so that the type and ejection pressure can be selected as appropriate, and if the fluid can be intermittently adjusted and adjusted independently, it can be easily adjusted by observing the contamination state of the cleaning surface. Often convenient. The foreign matter that has been stubbornly adhered by the surface abrasion polishing by the rotation of the rotating brush 41 and the rinsing action with the impact of high-pressure water etc. is forcibly peeled off and a clean bolster surface is regenerated.

A large number of injection nozzles 13 are provided on the outer side surface 12B of the frame 1, and are piped from the inside so that high-pressure water or compressed air can be injected outward respectively. The side frame of the press is facing this outer surface, and since many scales and lubricants are also scattered and fixed to this side frame at the time of forging, the bolster is used while the die holder is being renewed. In addition to cleaning the top surface, cleaning the press side frame often produces good results. FIG. 4 is a flow chart showing a piping system of an embodiment of the present invention, in which a compressed air supply port 45 and an air tank 46, a supply port 47 for injection fluid such as high-pressure water and high-pressure steam, and a switching device 48 therefor are interposed. Piped alone or intermittently together.

[0016]

[Effect of device]

 The bolster cleaning device for a forging press according to the present invention can automatically and strongly remove stubbornly stuck foreign matter with little human intervention. If it is used together with the die holder exchange device, the additional equipment can be used as it is, which is even more convenient. Even if this is not the case, cleaning work, which was inefficient and dangerous, which conventionally relies on human labor, will be eliminated, so it will be highly evaluated in terms of work safety, environmental improvement, and productivity improvement. Is recognized.
