Description

A kind of dual thimble structure
Technical field
The utility model relates to metal plate punching technical field of mold, more specifically to a kind of dual thimble structure.
Background technique
In metal plate punching material-removing structure, for needing to process the product of longer de- material stroke, due to amount of spring compression by It is closed height limitation to punching machine, causes thimble de- material stroke inadequate, it has to be produced using biggish punching machine.
Utility model content
The technical problem to be solved by the present invention is in view of the above drawbacks of the prior art, provide one kind certain It is closed in limit, increases de- material stroke, improve working efficiency, reduce the dual thimble structure of production cost.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
Construct a kind of dual thimble structure, including upper die holder;Wherein, it is fixedly connected with acting as a cushion below the upper die holder, The upper die holder is equipped with the first spring, and first spring end is equipped with the second screw, and second screw is far from described the One end of one spring is equipped with the first thimble, and first thimble is equipped with the first installation far from one end end of second screw Hole, first mounting hole is interior to be equipped with second spring, and the second spring end is equipped with the second thimble, and first mounting hole is set There is the diameter of one end of the second spring to be greater than the diameter of second thimble;The upper die holder and the upper acting as a cushion are equipped with With matched second mounting hole of first spring, the diameter of second mounting hole is greater than the diameter of first thimble;Institute One end end of first thimble closely from first spring is stated equipped with the first limited block, second thimble is closely from second bullet One end end of spring is equipped with the second limited block.
Dual thimble structure described in the utility model, wherein the upper die holder is equipped with the first screw, the upper acting as a cushion Lower section is fixedly connected with upper padding plate, is fixedly connected with cope plate below the upper padding plate;First limited block and described second Mounting hole matching.
Dual thimble structure described in the utility model, wherein the upper padding plate and the cope plate be equipped with it is described The third mounting hole of first thimble cooperation.
Dual thimble structure described in the utility model, wherein first mounting hole far from second screw one End is equipped with the second centre hole cooperated with second thimble, and the one end of first mounting hole closely from second screw is equipped with With the matched second spring hole of the second spring, second limited block is matched with the second spring hole.
The utility model has the beneficial effects that: the first spring and second spring bounce simultaneously in die sinking, the first spring First thimble is bounced, the second spring in the first thimble bounces the second thimble;The first spring and second spring are same when molding When compressed, the second thimble is shunk in the first thimble, and the first thimble is shunk in mould;It realizes in centainly closure limit, Increase de- material stroke, improve working efficiency, reduces production cost.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below in conjunction with attached drawing and reality Applying example, the utility model is described in further detail, and the accompanying drawings in the following description is only section Example of the invention, for this For the those of ordinary skill of field, without creative efforts, it is attached to can also be obtained according to these attached drawings other Figure:
Fig. 1 is the dual thimble structure die opening state schematic diagram of the utility model preferred embodiment;
Fig. 2 is the dual thimble structure molding status diagram of the utility model preferred embodiment.
Specific embodiment
It is practical below in conjunction with this in order to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Technical solution in new embodiment carries out clear, complete description, it is clear that described embodiment is the portion of the utility model Point embodiment, rather than whole embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not paying creation Property labour under the premise of every other embodiment obtained, belong to the protection scope of the utility model.
The utility model preferred embodiment as shown in Figure 1, simultaneously referring to Fig.2, include upper die holder 12, it is characterised in that; Acting as a cushion 13 is fixedly connected with below upper die holder 12, upper die holder 12 is equipped with the first spring 2, and 2 end of the first spring is equipped with second Screw 5, the second screw 5 far from the first spring 2 one end be equipped with the first thimble 16, the first thimble 16 far from the second screw 5 one End is held to be equipped with the first mounting hole 6,6 are equipped with second spring 7 in the first mounting hole, and 7 end of second spring is equipped with the second thimble 11, The diameter that first mounting hole 6 is equipped with one end of second spring 7 is greater than the diameter of the second thimble 11;Upper die holder 12 and upper acting as a cushion 13 are Equipped with matched second mounting hole 3 of the first spring 2, the diameter of the second mounting hole 3 is greater than the diameter of the first thimble 16;First top One end end of the needle 16 closely from the first spring 2 is equipped with the first limited block 4, one end end of second thimble 11 closely from second spring 7 Equipped with the second limited block 9;In die sinking, the first spring 2 and second spring 7 bounce simultaneously, and the first spring 2 is by 16 bullet of the first thimble It rises, the second spring 7 in the first thimble 16 bounces the second thimble 11;When molding the first spring 2 and second spring 7 simultaneously by Compression, the second thimble 11 are shunk in the first thimble 16, and the first thimble 16 is shunk in mould;It realizes in centainly closure limit, Increase de- material stroke, improve working efficiency, reduces production cost.
