Abstract

The utility model discloses a forging hydraulic press with a fast die-changing device, wherein an upper chopping block is arranged on a movable cross beam and provided with a locating pin; the upper chopping block is connected with an upper anvil through a round pin; the round pin is provided with a through hole; the upper chopping block is installed with an air cylinder; the end part of the piston of the air cylinder is fixedly installed with a small straining beam; two ends of the small straining beam are installed with plugs; and the plugs are positioned in the through hole in the round pin. Due to driving of two air cylinders and inserting of four plugs into the positioning round pins, the utility model can conveniently fix the upper anvil on the upper chopping block. When needing to replace the die, the die can be separated from or connected with the upper chopping block only by operating the button and pushing the plugs in or out by the air cylinders, thus having convenient and safe operation, greatly shortening the die-changing time with the actual die-changing time being about 1-2 minutes, and greatly improving the work efficiency.

Description

The hydraulic forging press that has quick die change device

Technical field

The utility model belongs to machine-building, relates in particular to a kind of hydraulic forging press that has quick die change device.

Background technology

Traditional hydraulic forging press mould changing device all is to adopt mechanical type to connect, and promptly backing plate pin-and-hole and moved cross beam manufacture, and plays the positioning action of anvil by alignment pin, backing plate and moved cross beam bolted on connection, and last anvil links to each other with last chopping block by drift.Need manually finish this procedure when replacing with anvil, waste time and energy, efficient is extremely low.

Summary of the invention

The purpose of this utility model provides a kind of hydraulic forging press that has quick die change device.

For achieving the above object, the utility model adopts following technical scheme: a kind of hydraulic forging press that has quick die change device, last chopping block is contained on the moved cross beam, on the last chopping block alignment pin is housed, last chopping block links to each other by round pin with last anvil, and through hole is arranged on the round pin, on the last chopping block cylinder is housed, the end of cylinder piston is fixed with little straining beam, and latch is equipped with at little straining beam two ends, and latch is arranged in the through hole on the round pin.

Cylinder has two, and symmetry is contained in the both sides of chopping block.

Adopt the hydraulic forging press of technique scheme, by two air cylinder driven, four latches insert in the round pin of location, very easily last anvil are fixed on the chopping block.When needing more mold exchange, need only action button, by cylinder latch to be released or advanced, mould can throw off or be connected with last chopping block, and is easy and safe to operate, shortened mould replacing time greatly, and actual mould replacing time is about 1-2 minute, has improved operating efficiency greatly.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A-A of Fig. 1 is to view.

Fig. 3 looks schematic diagram for the left side of Fig. 2.

The specific embodiment

As Fig. 1, Fig. 2, the hydraulic forging press that has quick die change device shown in Figure 3, last chopping block 1 is installed on the moved cross beam by bolt, and by alignment pin 2 and moved cross beam location.Last chopping block 1 links to each other by round pin 5 with last anvil 3, on the round pin 5 through hole is arranged, last chopping block. on cylinder is housed, the end of cylinder piston 4 is fixed with little straining beam 6, latch 7 is equipped with at little straining beam 6 two ends, latch 7 is arranged in the through hole on the round pin 5.

When needs replace with anvil 3, stretch out button by lower cylinder, cylinder piston 4 stretches out, and the little straining beam 6 that is connected pistons end is taken out of simultaneously, is also taken out of simultaneously with the latch 7 that little straining beam links together, and takes down round pin 5 then, just can disassemble last anvil.Then opposite during installation, after round pin 5 is in place, press the lower cylinder retraction button, then cylinder piston 4 drives latch 7 backhauls by little straining beam 6, injects in the pin-and-hole of round pin 5, and so far, last anvil is changed and is put in place.This covering device has conveniently quick die change function, can carry out special operations such as heat carrying mould replacing, has satisfied the demand of main equipment quick anvil changing, has shortened service working time, has improved forging efficient.Cylinder seal adopts the sealing of metal piston ring in this device, has resistant to elevated temperatures advantage.

Claims (2)

1. hydraulic forging press that has quick die change device, last chopping block is contained on the moved cross beam, on the last chopping block alignment pin is housed, it is characterized in that: go up chopping block and link to each other by round pin with last anvil, through hole is arranged on the round pin, on the last chopping block cylinder is housed, the end of cylinder piston is fixed with little straining beam, latch is equipped with at little straining beam two ends, and latch is arranged in the through hole on the round pin.
2. the hydraulic forging press that has quick die change device as claimed in claim 1 is characterized in that, cylinder has two that symmetry is contained in the both sides of chopping block.
