Description

Ball neck connects arm forging press tool

Technical field

The utility model relates to a kind of press tool, and feature relates to ball neck and connects arm forging press tool.

Background technology

Need when ball neck connects arm forging punch die in the prior art first to connect at ball neck with punching die on 160 tons of enclosed pressing machinees arm forging is gone out middle hole, then from 160 tons of pressing machinees, ball neck is connect arm forging to take off, then it is transported to and ball neck is connect arm forging with hot Correction Die by 630 tons of pressing machinees corrects. This kind of technique corrects due to first punching again, and middle hole wall is thin, and non-contacted supports and loses circle after calibration, has become ellipse, can not meet requirement; If first correcting punching again, owing to operation is excessively long, the decrease in temperature of middle hole wall and gross weight, in the middle of after punching, hole hole wall deformation is big, need to again correct; And consuming two equipment, two operative employees, single piece production time length, production efficiency is low and cost height.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of ball neck and connects arm forging press tool, ball neck is connect arm forging correction and punching can be completed on same pressing machine, and after punching, middle hole hole wall is not out of shape, the single piece production time is short, production efficiency height and cost low.

In order to solve the problem, the technical solution of the utility model is: ball neck connects arm forging press tool, comprise die holder, lower die holder, it is placed in die holder upper module and upper die plate, the lower module being placed in lower die holder and counterdie backing plate, the guide pillar being fixedly mounted on lower die holder, the guide pin bushing for positioning guide column being arranged in die holder, what be arranged on die holder and lower die holder is multiple for regulating upper module and the adjusting bolt of lower module position, lower die holder has been offered the first through hole, lower module has been offered the 2nd through hole, third through-hole offered by counterdie backing plate, and the first through hole, 2nd through hole and third through-hole are coaxial, one piece of cushion block it is mounted with respectively at the two ends of the lower end of lower die holder, in the gap of the projection plane of the first through hole between two pieces of cushion blocks, also comprise a drift that can pass through from the first through hole and the 2nd through hole, the height of drift is less than the thickness of cushion block.

The beneficial effects of the utility model are: this mould first corrects, then punching, again ball neck is connect arm forging and correct while punching, originally three stations are focused on a station suppressed for twice, and hole is not out of shape, workpiece physical dimension is ensured, thus effectively ensure that the quality of workpiece;Operation corrects punching station after concentrating and just can complete for 20 seconds, and the temperature of workpiece can meet correction punching, therefore it is constant to produce beat; Decreasing one, 160 tons of closed single point pressing machinees, an operative employee, decrease frock, mould a set of, production cost obtains reduction.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 of the present utility model partly cuts open schematic diagram,

Fig. 2 be mentioned by the utility model to ball neck connect the perspective view of arm forging,

Fig. 3 is the vertical view of the utility model lower module,

Fig. 4 is the diagrammatic cross-section at A-A place in Fig. 3,

Fig. 5 is the vertical view of the utility model upper module,

Fig. 6 is the diagrammatic cross-section at B-B place in Fig. 5,

The diagrammatic cross-section of Fig. 7 the utility model when using upper module and lower module punching press.

Fig. 8 be in above-mentioned background technology mentioned to prior art in utilize enclosed pressing machine that ball neck connects arm forging to carry out punching press or partial cutaway schematic when mould corrects.

Embodiment

The technical progress understood the utility model to more allow those skilled in the art and prior art done, before being elaborated by the utility model, first to connecing the punching course of arm forging about ball neck in prior art and step elaborates.

If Fig. 2 is the perspective view that ball neck connects arm forging, the C place shown in figure connects hole in the middle of arm forging for ball neck, and ball neck connects arm forging before undressed, and it is plane that the ball neck of the position in middle hole connects arm forge piece blank reheating.

If Fig. 3 is to shown in 8, in the prior art, lower module 4 is not there is hole, need when ball neck connects arm forging punch die first to connect at ball neck with punching die on 160 tons of enclosed pressing machinees arm forging is gone out middle hole, then from 160 tons of pressing machinees, ball neck is connect arm forging to take off, then it is transported to and ball neck is connect arm forging with hot Correction Die by 630 tons of pressing machinees corrects. This kind of technique corrects due to first punching again, and middle hole wall is thin, and non-contacted supports and loses circle after calibration, has become ellipse, can not meet requirement; If first correcting punching again, owing to operation is excessively long, the decrease in temperature of middle hole wall and gross weight, in the middle of after punching, hole hole wall deformation is big, need to again correct; And consuming two equipment, two operative employees, the single piece production time is long, and production efficiency is low, cost height, and 160 tons of above-mentioned pressing machinees are identical with the profile of 630 tons of pressing machinees, and shape is as shown in Figure 8.

Below the utility model is described in further detail:

If Fig. 1 is to shown in 6, ball neck connects arm forging press tool, comprise die holder 1, lower die holder 2, it is placed in die holder 1 upper module 3 and upper die plate 10, the lower module 4 being placed in lower die holder 2 and counterdie backing plate 5, the guide pillar 7 being fixedly mounted on lower die holder 2, the guide pin bushing 8 for positioning guide column 7 being arranged in die holder 1, what be arranged on die holder 1 and lower die holder 2 is multiple for regulating upper module 3 and the adjusting bolt 11 of lower module 4 position, lower die holder 2 has been offered the first through hole 41, lower module 4 has been offered the 2nd through hole 51, counterdie backing plate 5 has been offered third through-hole 21, and the first through hole 41, 2nd through hole 51 and third through-hole 21 are coaxial, one piece of cushion block 6 it is mounted with respectively at the two ends of the lower end of lower die holder 2, in the gap of the projection plane of the first through hole 41 between two pieces of cushion blocks 6, also comprise a drift 9 that can pass through from the first through hole 41 and the 2nd through hole 51, the height of drift 9 is less than the thickness of cushion block 6.

Operating process of the present utility model:

The first step, ball neck is connect arm forging it is placed in lower module 4 model cavity to hit once correct;

2nd step, middle hole site drift 9 is placed on ball neck connecing arm forging are hit once, simultaneously having corrected of punching, and drift 9 drops on the worktable 12 between two cushion blocks 6 by the first through hole 41, the 2nd through hole 51 and threeway successively simultaneously;

3rd step, taking-up ball neck connect arm forging finished product, take out drift 9 and hole gross weight in the gap between two pieces of cushion blocks 6, hole gross weight and ball neck are connect arm forging finished product and puts into respective Turnover Box, and drift 9 is purchased.

The utility model adopts first to correct, then punching, again ball neck is connect arm forging and correct while punching, originally three stations are focused on a station suppressed for twice, and hole is not out of shape substantially, workpiece physical dimension is ensured, thus effectively ensure that the quality of workpiece; Operation corrects punching station after concentrating and just can complete for 20 seconds, and the temperature of workpiece can meet correction punching, therefore it is constant to produce beat; Decreasing one, 160 tons of closed single point pressing machinees, an operative employee, decrease frock, mould a set of, production cost obtains reduction.
