Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pressurizing device mainly used for polishing a work hole such as a hole of a deformed die or a hole of a die.

[Conventional technology]

Conventionally, for example, for die hole polishing, a die polishing machine (A) as shown in FIG. 3 is used, a die (D) is placed on a work table (9), and a chip portion (D) of this die (D) is placed. After inserting the polishing punch (10) into the hole of ₁ ), the polishing punch (10) is moved up and down, and the die (D) is moved to the rubber (11) as shown in Fig. 4 (a) (b). Alternatively, the pressure was applied with the hand (12).

[Problems to be solved by the device]

However, when the rubber (11) is pressed and polished, it is always pressed with a fixed direction and force, so it is not possible to deal with various hole shapes of the irregular shape die, and it is difficult to adjust the pressing force. There was a problem.

Further, when polishing by pressing with the hand (12), not only skill is required, but even a skilled worker is difficult to adjust the pressing direction and the pressing force according to the hole shape of the die, which requires a great deal of labor. There was a problem that it took.

In addition, the same problem was encountered in the hole polishing work of the mold.

The present invention has been made in view of the above problems, and by mechanizing the hole polishing work of the work, no skill is required, and the pressurizing force and the like are adjusted according to the hole shape to obtain a good quality work. It is an object of the present invention to provide a work hole polishing pressurizing device capable of polishing a hole.

[Means for solving problems]

In order to achieve the above object, the work hole polishing pressurizing device of the present invention has a work mount having a work mount jig in the center, which is movably arranged in the upper center of the work table. A plurality of pressurizing means such as an air cylinder, a hydraulic cylinder, a solenoid valve and the like are arranged at required intervals, and these pressurizing means and a work mounting base are attached by a transmission member.

Further, the pressurizing means is connected to an automatic control section of a computer so that the pressurizing force can be selectively and operably activated.

Further, as the above-mentioned transmission member, in addition to the spring, rubber or resin having elasticity is suitable in order to correspond to the delicate part of the hole shape of the work and to absorb it well when an excessive load is applied. Is.

By the way, the pressing means can be pulled or pressed, and the transmission means can be selected according to this.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a pressure device for polishing a work hole according to the present invention.
(1) is a work table arranged below the polishing punch of the polishing machine, and a work mount (2) is movably arranged at the center of the upper part of the work table (1). Above work mount
(2) is provided with a work mounting jig (3) having a work mounting hole (4) at the center of the upper part thereof.

Further, a plurality of (for example, eight) air cylinders (5) are arranged at equal intervals on the outer circumference of the work table (1), and the air cylinders (5) and the work mount (2) And (5) and (5) are respectively engaged by springs (6) to constitute a desired work hole polishing pressurizing device. In the figure, (7) is an air cylinder fixing base and (8) is a base.

Further, each air cylinder (5) of the pressurizing device is connected to an automatic control unit of a computer (not shown). In the storage unit of the computer, the pulling direction, pulling time, pulling force, etc. of each air cylinder are stored in a program corresponding to the hole shape of the work (for example, die), and the movement of each air cylinder is automatically controlled. The unmanned polishing work for the holes of various shaped dies is performed.

By the way, when the die is polished using the work hole polishing pressurizing device, when the processing die (D) is set in the work mounting hole in FIG. 2 and the air cylinder is operated in the direction of to pull the spring, , The die hole surface on the side is pressed against the polishing punch, and the polishing punch moves up and down to be polished,
The air cylinder is operated in a sequential direction to polish the die hole.

Also, change the air cylinder () → ()
→ () → () works to pull the spring to easily grind the track-shaped die hole.

[Effect of device]

According to the present invention, it is possible to easily and accurately polish a hole for a workpiece without requiring the work of a skilled worker.
It has a practical effect that the pressing force, the pressing direction, the pressing time, etc. can be adjusted according to the work, and the automatic control can be performed to save labor.
