Description
Technical field
The present invention relates to technical field of mold, be specifically related to punching press cross cutting large hypotenuse mould and cut large hypotenuse method.
Background technology
At present, the processing mode of domestic known (for the steel backing of automobile brake sheet shown in such as Fig. 1) large hypotenuse of workpiece 71 (the large hypotenuse of such as steel backing) to ramming workpiece 7 is all use the flanging by force of 500T hydraulic press, and product plane degree is seriously bad after having pressed hypotenuse, need another 500T pressing plate for oil press thick, like this, under efficiency, bring great puzzlement to the batch production of product and quick production, also add the production cost of product simultaneously significantly.Large hypotenuse in the application refers generally to the hypotenuse that hypotenuse arc length or hypotenuse two ends air line distance are greater than 30mm.The producer that minority has a direct die-cut large hypotenuse technology can not make hypotenuse euphotic belt reach absolutely, and changes due to other size of product when mould structure reason causes die-cut hypotenuse.So the high speed of the large hypotenuse of product, qualified production are generally considered a technical barrier being difficult to greatly capture in punching production industry.
Prior art is compared, beneficial effect of the present invention:
1, the present invention relates to die-cut to the large hypotenuse of stamping products of punching press cross cutting large hypotenuse mould structure.The invention provides the large hypotenuse mould of punching press cross cutting, this mould structure and die-cut production method effectively can not only improve production production capacity and can also ensure that the quality of product is qualified, ensure that institute's euphotic belt of die-cut can reach a hundred per cent.
2, the present invention adopts oblique sliding groove structure, the vertical direction blanking pressure cleverly punch press provided, by the supporting seat with the oblique chute of certain angle track that the mould left and right sides is bumped into, order about the blanking pressure that main drift produces oblique line directions, thus large hypotenuse at any angle can be punched out, two cutting edges (i.e. the first cutting edge and the second cutting edge) are had in conjunction with main drift knife-edge part, hypotenuse is enable to reach absolutely euphotic belt, ensure that mould can punch out high-quality product, ensure that mould can the production of safety high speed.
3, main drift and lower bolster are designed to dismountable activity form, the die-cut switching of other similar money product can be carried out fast.
4, mould structure design economy of the present invention, rationally, science, efficient, hypotenuse can ensure that hypotenuse has absolutely euphotic belt can be cut out to product fast, well solve that other production capacity of cutting hypotenuse mould is low, euphotic belt is poor and quality is difficult to the problem that ensures.Hypotenuse can be cut to other similar money product fast by replacing lower bolster and main drift to produce.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.
The large hypotenuse mould of punching press cross cutting as shown in Fig. 2 to Fig. 9, the main drift 3 comprise counterdie 1, be located at the supporting seat 2 of counterdie 1, coordinating with this supporting seat 2 activity and patrix 4, patrix 4 is provided with the holding pad 41 for workpiece pressing 7, main drift 3 is between counterdie 1 and patrix 4 and be positioned at the position of matching with workpiece 7, and supporting seat 2 is provided with the oblique chute 21 be connected with main drift 3; Patrix 4 presses down main drift 3 and simultaneously workpiece pressing 7, and main drift 3 is along the displacement of oblique chute 21 and the limit of workpiece 7 of cutting sth. askew thus to realize workpiece large hypotenuse 71 shaping.In this process, the power of punch press vertical direction is passed to main drift 3 by the force transmitting board 42 of patrix 4, and main drift 3 is along the displacement of oblique chute 21, and the power of this vertical direction is changed into the power of oblique line directions by main drift 3, realizes cutting hypotenuse to workpiece 7 and workpiece large hypotenuse 71 is shaping.In the present embodiment, workpiece 7 lies in a horizontal plane on the lower bolster 11 of counterdie 1.
In the present embodiment from bottom to up, counterdie 1 comprises die shoe 11, the lower plate 12 be located on die shoe 11, the lower bolster 13 be located on lower plate 12, two relative supporting seats 2 lay respectively at lower bolster 13 two ends, main drift 3 is positioned at above lower bolster 13, and main nose of punch 31 to stretch in oblique chute 21 and coordinates with oblique chute 21 activity; The bottom surface of main nose of punch 31 is also connected with the bottom of oblique chute 21 by back-moving spring 5, and after realizing rushing hypotenuse, main drift 3 resets.The workpiece 7 of hypotenuse to be cut is placed horizontally on lower bolster 13, workpiece 7 limit to be cut be positioned at main drift 3 below and and main drift 3 coordinate.Die shoe 11 is provided with alignment pin 48 for locating workpiece 7 and block 49, prevents workpiece 7 in punching course from offseting.Main drift 3 in the present embodiment and supporting seat 2 removably connect, and lower bolster 13 and lower plate 12 removably connect, and only need more change owner drift 3 and lower bolster 13 just can cut hypotenuse to other similar money product fast and produce.
Main drift 3 in the present embodiment comprises the first cutting edge 32 and the second cutting edge 33, first cutting edge 32 realizes the preformed of workpiece large hypotenuse 71 for the size punching out the large hypotenuse of workpiece 71, then main drift 3 continues descending, and the second cutting edge 33 extrudes the large hypotenuse 71 of workpiece thus forms absolutely euphotic belt.
Patrix 4 also comprises force transmitting board 42, train wheel bridge 43, the upper frame plate 44 be located on train wheel bridge 43, the die shank 46 being located at the upper bolster 45 on frame plate 44 and being located on upper bolster 45 from bottom to up.Force transmitting board 42 to be fixed in train wheel bridge 43 and by the affixed upper frame plate 44 of bolt 6 and upper bolster 45, to realize when mould open/close mould force transmitting board 42, train wheel bridge 43, on frame plate 44 and upper bolster 45 be synchronized with the movement.Holding pad 41 to be positioned at below train wheel bridge 43 and to be connected with lower plate 43, is folded with rubber 47 between holding pad 41 and train wheel bridge 43, and is connected by guide pillar between holding pad 41 and train wheel bridge 43 and realize guiding.
Other structure of the large hypotenuse mould of the present embodiment punching press cross cutting is see prior art.
As further illustrating the present embodiment, what the present embodiment was now described cuts large hypotenuse method:
When S1, patrix 4 descending matched moulds, holding pad 41 pushes down workpiece 7, patrix 4 continues descending, the power of punch press vertical direction is passed to main drift 3 by force transmitting board 42, the inclined-plane of main drift 3 oblique chute 21 in edge under the ordering about of the oblique chute 21 of supporting seat 2 moves, and the first cutting edge 32 punches out the size of the large hypotenuse 71 of workpiece;
S2, patrix 4 continue descending, and the second cutting edge 33 of main drift 3 extrudes the large hypotenuse 71 of workpiece thus forms absolutely euphotic belt;
S3, the up die sinking of patrix 4, force transmitting board 42 is separated with main drift 3, and the back-moving spring 5 in supporting seat 2 by main drift 3 jack-up, thus can carry out taking out and putting into workpiece smoothly.
The present invention is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or modification, if these are changed and modification belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these change and modification.
