Description

[Detailed description of the invention] (Related technical field) The present invention prevents cooling water and lubricant from entering between the press die holder and the bed hard plate, and also greatly reduces scale removal during setup changes. The invention relates to a device that can facilitate

(Prior technology) In conventional press die holders, a sealing mechanism using an O-ring, etc. was used between the bed and the bed hard plate to prevent wear caused by intrusion of cooling water and lubricant. . However, the die holder is a part that can be replaced in stages, and it is considered difficult to install a sealing mechanism, making it unavoidable for cooling water or lubricating oil contaminated with scale to enter between the die holder and the bed hard plate. was. For this reason, when removing the die holder, cleaning the mating surfaces of both die holders was a step in the setup change work. Moreover, if this work is neglected, not only will the degree of wear on both parts increase, but there is also a risk that cracks will develop due to scale encroachment.

(Problems to be solved by the invention) 1) It is possible to prevent wear of the die holder and bed hard plate caused by liquid entering between the die holder and bed hard plate,
2) To enable cleaning of mating surfaces during setup changes in a short time; 3) To prevent damage and cracking of the die holder caused by scale getting caught between the die holder and bed hard plate; To achieve the above points, it is an object of the present invention to provide a device that prevents scale from entering the lower surface of a die holder.

(Devised solution) A cooling and lubricant recovery guide is provided on the circumferential side of the lower die holder, and correspondingly, a recovery channel is provided around the lower die holder on the inside of the press frame so as to overlap the guide downwardly. Ta. In addition, by constantly supplying water called recovery, the scale received in the recovery funnel was flushed out and removed.

(Embodiment of the invention) 1 is an upper die holder, and an upper mold 2 is attached to this. A press slide 3 moves the upper die holder 1 up and down.

4 is a lower mold, which is mounted on the lower die holder 5. 6 is a bed hard plate, and 7 is a bed. Reference numeral 8 denotes a guide attached to the circumferential side of the lower die holder 5, and the cooling/lubricating liquid jetted from the nozzle described later is guided by this guide 8.
The waste water is received by a recovery gage 9 provided below and overlapping with the waste water, and is discharged from a drainage pipe 10 into a pit (not shown).

11 is a press frame; the press frame 1
A collection gutter 9 surrounding the lower die holder 5 is attached to the inside of the die holder 1 . Reference numeral 12 denotes a guide post of the upper die holder 1, which is erected on the lower die holder 5.

13 is a nozzle provided on the press frame 11;
Cooling and lubricating fluid 14 is spouted from this. Note that the nozzle 13 may be attached to the upper die holder 1 or the lower die holder 5. 15 is the water supply pipe,
It is related to collection 9. Due to this water supply, the scales and the like collected in the collection gutter 9 are completely discharged toward the drain pipe 10 without being deposited, allowing continuous cooling and lubrication operations.

(Function of the device) During or after the press frame 3 is raised, the press frame 11 or the upper and lower die holders 1,
Cooling and lubricating liquid 14 is injected by a nozzle 13 attached to 5 or the like.

The injected cooling/lubrication liquid 14 is transmitted from the upper surface of the lower die holder 5 to the peripheral side surface, and flows down from the guide 8 into the recovery channel 9. The cooling/lubrication liquid 14 that has flowed down into the recovery gutter 9 flows into the drainage pipe 10 together with the scale by water flowing from the water supply pipe 15 connected to the recovery gutter 9. In addition, the guide 8 and recovery pipe 9 not only prevent the cooling and lubricating liquid 14 flowing down from entering between the lower die holder 5 and the bed hard plate 6, but also serve as a cover to prevent the scale and spray liquid scattered by the injection from entering. I am accomplishing it.

(Effects of the invention) Since the injected cooling and lubricating liquid flows through the guide to the recovery port, 1) it does not enter between the die holder and the bed hard plate; Therefore, it is possible to prevent these wear due to scale and the like. 2) When removing the die holder during setup change,
The cleaning work of the mating surfaces at this time becomes extremely quick and easy. 3) It is possible to prevent damage and cracks caused by scale getting caught between the die holder and the bed hard plate.
