Abstract

A horizontal punch die for notch of small crossbeam, which is provided by the utility model, comprises the following components: a lower die bed, an upper die bed, guide sleeves, guide pillars, an inclined wedge connected with the upper die bed, a fixed cutting edge provided at the middle part of the lower die bed, and movable cutting edges which are provided at die slide blocks that are inserted into chutes provided in the lower die bed. The movement of the die slide blocks is realized through the inclined wedge provided therebetween. The inclined wedges convert the vertical movement of the upper die bed to horizontal movement of die slide blocks. The horizontal punch die for notch of small crossbeam settles a technical problem that the notch punching after bending the plate is hard to realize in background technology. Not only is punching for processing the notch of the plate after bending the plate realized, but also the cold rolled section steel can be adopted as the raw material. The horizontal punch die for notch of small crossbeam has the advantages of enlarging the use range of raw material, reducing production steps, reducing the higher requirement to the device, and eliminating the effect of the bending step to quality of the notch.

Description

The horizontal punching out mould of needle beam breach
Technical field
The utility model relates to a kind of punching out mould, is specifically related to a kind of horizontal punching out mould of needle beam breach.
Background technology
Needle beam is an important stamping parts in the general truck of 70t as shown in Figure 1, and every chassis quantity is 24, and breach is processed as the important procedure that needle beam is made.Compare with other processing, the stamping-out of breach is most economical processing mode.But generally, the stamping-out direction is consistent with the press ram direction of motion, and perpendicular to horizontal plane, traditional punch die structure causes breach processing to carry out before the plate bending, is difficult to realize the punching out of breach after the plate bending.
Summary of the invention
The purpose of this utility model is to provide a kind of horizontal punching out mould of needle beam breach, and it has solved the technical problem that is difficult to realize breach punching out after the plate bending in the background technology after the plate bending.
The technical solution of the utility model is:
A kind of horizontal punching out mould of needle beam breach, comprise die shoe, upper bolster, guide pin bushing, guide pillar, what be connected with upper bolster tiltedly carves, be arranged at the fixedly cutting edge at die shoe middle part, be arranged at the movable cutting edge of mould slide block, described mould slide block is embedded in the chute that is arranged at die shoe inside, its special character is: the motion of described mould slide block is to realize that by the wedge that is arranged between them wedge is converted into moving both vertically of upper bolster the horizontal movement of mould slide block.
Above-mentioned guide pin bushing waters with low-melting alloy and is fixed on the upper bolster, and the guide pillar interference is pressed in the die shoe, and the blade clearance guarantees with the fit clearance of guide pillar guide pin bushing.
Be provided with spring between above-mentioned mould slide block and the die shoe, this spring is provided with spring cup, screw rod and nut, and screw rod is connected with mould slide block.During work, mould slide block drives screw rod and makes the spring compression to the motion of mould middle part, when forcing press is up, utilizes spring that mould slide block is resetted, and has guaranteed the carrying out of punching out circulation.
Said fixing cutting edge and movable cutting edge all are to realize the location by alignment pin.
Above-mentioned die shoe inboard also is provided with brake pad, guarantees the stress balance of tiltedly carving.
Advantage of the present utility model is: plate breach processing has not only been realized punching out after the plate bending, and raw material can adopt cold-rolled forming section, enlarged the raw material scope of application, reduced production process simultaneously, reduced the equipment high requirement, eliminated the influence of bender's ordered pair breach quality.

Fig. 1 is a needle beam stamping parts structural representation; Wherein scheme the vertical view of a for this structural member; Figure b is the transverse views of this structural member.
Fig. 2 is the utility model structural representation.
Description of reference numerals: the 1-die shoe, the 2-guide pillar, the 3-guide pin bushing, the 4-upper bolster, 5-is cutting edge fixedly, 6-mould slide block, the movable cutting edge of 7-, 8-chute, 9-wedge, 10-spring, 11-spring cup, 12-alignment pin, 13-screw rod, 14-nut, 15-brake pad.
The specific embodiment
Referring to Fig. 2, a kind of horizontal punching out mould of needle beam breach, comprise die shoe 1, guide pillar 2, guide pin bushing 3, upper bolster 4, be arranged at the fixedly cutting edge 5 at die shoe 1 middle part, the mould slide block 6 that is connected with upper bolster 4 is arranged at the movable cutting edge 7 of mould slide block 6 ends, and the lower end of mould slide block 6 is embedded in the chute 8 that is arranged at die shoe 1 inside, the motion of mould slide block 6 is to realize by the wedge 9 that is arranged between them, wedge 9 is connected with upper bolster 4, and when forcing press was descending, wedge 9 was converted into moving both vertically of upper bolster 4 horizontal movement of mould slide block 6; Guide pin bushing 3 waters with low-melting alloy and is fixed on the upper bolster, and guide pillar 2 interference are pressed in the die shoe, and the blade clearance guarantees with the fit clearance of guide pillar guide pin bushing; Be provided with spring between mould slide block 6 and the die shoe 1, this spring is provided with spring cup 11, screw rod 13 and nut 14, and screw rod 13 is connected with mould slide block 6.During work, mould slide block 6 drives screw rod 13 and makes spring 10 compressions to the motion of mould middle part, when forcing press is up, utilizes spring 10 that mould slide block 6 is resetted, and has guaranteed the carrying out of punching out circulation.Also be provided with brake pad 15 between wedge 9 and die shoe 1 inboard, guarantee tiltedly to carve 9 stress balance.
The course of work is as follows: the semi-finished product after the bending or cold-rolled forming section button are placed on fixedly on the cutting edge 5, with alignment pin 12 location, when forcing press is descending, the wedge 9 that is fixed on the upper bolster 4 acts on mould slide block 6, mould slide block 6 moves in the horizontal concrete chute 8 of die shoe 1, wedge 9 is the horizontal movement that forcing press moves both vertically and is converted into, and makes to be installed on the mould slide block 6 movable cutting edge 7 and to finish the breach punching out with the fixedly cutting edge 5 that is installed in die shoe 1 middle part.When forcing press is up, utilize spring 10 that mould slide block 6 is resetted, guaranteed the carrying out of punching out circulation.
