Abstract
The invention discloses a counter punching mechanism for processing both sides of a square tube, which comprises an upper die plate and a lower die plate arranged oppositely. One surface of the upper die plate facing the lower die plate is elastically connected with an upper pressing plate, an upper punch is disposed inside the upper pressing plate, the lower end of the upper punch facing the lower die plate is protruded from the upper pressing plate, a lower pressing plate is arranged on one surface of the lower die plate facing the upper die plate, a lower punch is disposed inside the lower pressing plate, the upper end of the lower punch facing the upper die plate is protruded from the lower pressing plate, a square tube required to be punched is disposed in a space reserved between the upper pressing plate and the lower pressing plate, and a female core can be held in the square tube. Two opposite sides of the square tube can be punched with holes by the counter punching mechanism so that mould cost is saved. Since both sides are punched simultaneously, procedures are saved, and punching efficiency is increased. Besides, the number and position of the upper punch and the lower punch can be set according to quantity and position of holes required to be punched on the square tube, and accordingly the counter punching mechanism for processing both sides of the square tube has higher flexibility and universality.
Description
Technical field
The present invention relates to a kind of diel, relate in particular to the two-sided mechanism that liquidates of a kind of square tube.
Background technology
When on two of square tube relative faces, all needing punching in the prior art, need two procedures usually, to each face difference punching press once, punching efficient is lower.If adopt a cover diel; Then after to the one side punching press; The operation that need overturn to square tube, and then another side carried out punching press, reduced punching efficient; And one hole number, position on two faces dashing of cover diel all identical, can't two faces of punching press on punching quantity, the different square tube in position; If adopt two cover diels, then increased die cost, strengthened human cost and board cost.
Summary of the invention
Technical problem to be solved by this invention provides the two-sided mechanism that liquidates of a kind of square tube, only needs to adopt a mold, can on two opposite faces of square tube, realize punching, and quantity, different hole, position on can two faces of punching press square tube.
For solving the problems of the technologies described above, the present invention provides a kind of square tube the two-sided mechanism that liquidates, and it is characterized in that, comprises the cope match-plate pattern and the lower bolster that are oppositely arranged,
Said cope match-plate pattern connects holding pad on towards a surface elastic of said lower bolster, and said going up in the holding pad is provided with upper punch, and said upper punch protrudes from the said holding pad of going up towards the bottom of lower bolster direction;
Said lower bolster is provided with holding pad towards the one side of said cope match-plate pattern, is provided with low punch in the said following holding pad, and said low punch protrudes from said holding pad down towards the upper end of cope match-plate pattern direction;
Said space of going up between holding pad and the following holding pad is used to place the square tube that needs punching,
Also comprise the master mold core that can be contained in the square tube.
Said master mold core is respectively arranged with the groove that can hold said upper punch bottom, low punch upper end on said two surfaces that go up to dash with low punch.
Said cope match-plate pattern is connected through first spring with the said holding pad of going up.
The another side of said lower bolster connects second spring.
The elastic force of said first spring is less than the elastic force of said second spring.
Said first spring is the rectangle spring.
Said second spring is a polyurethane spring.
Also be provided with the locating piece that square tube is positioned on the holding pad under said.
The beneficial effect that the present invention reached:
The two-sided mechanism that liquidates of square tube of the present invention only needs to adopt a mold, can on two opposite faces of square tube, realize punching, has saved die cost; And two sides punching press has simultaneously reduced operation, has improved punching efficient.If the quantity in the hole on two opposite faces of square tube, position are not simultaneously, only need corresponding respectively quantity and the position that upper punch, low punch are set to get final product, make the two-sided mechanism that liquidates of square tube of the present invention have flexibility better and versatility.
Description of drawings
Fig. 1 is the two-sided mechanism's front view that liquidates of square tube of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Like Fig. 1, Fig. 2 and shown in Figure 3, the two-sided mechanism that liquidates of square tube of the present invention comprises upper and lower cope match-plate pattern that is oppositely arranged 1 and lower bolster 2.
The lower surface elasticity of cope match-plate pattern 1 connects holding pad 3 on, be provided with upper punch 5 in the last holding pad 3, and upper punch 5 protrudes from holding pad 3 towards the bottom 51 of lower bolster 2 directions.Wherein, cope match-plate pattern 1 is connected through compression spring 7 with last holding pad 3, and spring 7 can be selected the rectangle spring for use.
Also be provided with the locating piece 21 that is resisted against master mold core 10 two ends on the lower bolster 2, thereby carry out the location, position being placed in master mold core 10 outer square tubes 9.
The below of lower bolster 2 is connected with bedplate 12 elasticity, specifically can be connected with bedplate 12 through compression spring 8.Spring 8 is selected polyurethane spring.Number of springs can be set to a plurality of, is provided with 4 in the present embodiment, and the elastic force of the spring 8 of lower bolster 2 connections is greater than the elastic force of the spring 7 of cope match-plate pattern 1 connection.When cope match-plate pattern 1 is pressed down, reach the rigidity of rectangle spring earlier, upper punch 5 thrusts the tube wall on plane on the square tube 9 earlier under the support of master mold core 10, and the bottom 51 of upper punch 5 gets in the groove 11 of master mold core 10 upper surfaces.Cope match-plate pattern 1 continues to press down then, reaches the rigidity of polyurethane spring, and low punch 6 thrusts the tube wall of square tube 9 lower surfaces under the support of master mold core 10, and the upper end 61 of low punch 6 gets in the groove 11 of master mold core 10 lower surfaces.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
