Description

A kind of floating rotating edge-trimming cutter structure of stamping die
Technical field
It the utility model is related to mould, more particularly to a kind of floating rotating edge-trimming cutter structure of stamping die.
Background technology
Traditional edge-trimming cutter generally uses tangent or chamfered design in design, i.e. upper mold edge-trimming cutter is directly installed on upper mold On, lower die edge-trimming cutter is directly installed in lower die;As lathe sliding block moves up and down, upper mold trimming cutter block and lower die trimming cutter block Shear action is completed, so as to complete the trimming process of part.This structure existing defects is mainly:
1)Using this kind of structure, there must be certain trimming lap two trimming cutter block junctions;It is required during trimming One cutter block is first cut, and is cut after another, will so be produced in the place for repeating to cut and be connect knife and have some setbacks, burr, iron filings etc., and is produced Iron filings again be easily brought into die face cause piece surface to weigh wounded, convex-concave point the problems such as;
2)At the same time in Jiao Daochu, two upper mold cutter block cutting edges are sharper relatively thin, make its remitted its fury, and cutting edge needs part at lower die Sky is allowed also to make its remitted its fury that tipping easily occur.
The content of the invention
In order to solve the problems of the prior art, the utility model provides a kind of floating rotating edge-trimming cutter of stamping die Structure.
The utility model provides a kind of floating rotating edge-trimming cutter structure of stamping die, including upper die and lower die, described Upper mold includes upper mold seat, spring, upper mold trimming cutter block, swivel bearing and rotation trimming cutter block, the upper mold trimming cutter block and fixes On the upper mold seat, the rotation trimming cutter block with the swivel bearing with the upper mold seat by being rotatably connected, the bullet Spring is arranged on the left end of the rotation trimming cutter block, and the right end of the rotation trimming cutter block is close to the upper mold trimming cutter block, institute Stating lower die includes placing restrictions on block, lower die trimming cutter block, lower die waste knife and die holder, described to place restrictions on block, lower die trimming cutter block, lower die Waste knife is separately fixed on the die holder, and the block of placing restrictions on is engaged with the left end of the rotation trimming cutter block, under described Cross cutting side cutter block is engaged with the upper mold trimming cutter block, and the lower die waste knife and the right end of the rotation trimming cutter block match Close.
As further improvement of the utility model, the left end of the rotation trimming cutter block is equipped with to match with the block of placing restrictions on The lug boss of conjunction.
The beneficial effects of the utility model are:Through the above scheme, burr can be reduced, avoids that tipping occurs.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of the floating rotating edge-trimming cutter structure of stamping die of the utility model.
Fig. 2 is a kind of schematic diagram of the upper mold of the floating rotating edge-trimming cutter structure of stamping die of the utility model.
Fig. 3 is a kind of schematic diagram of the lower die of the floating rotating edge-trimming cutter structure of stamping die of the utility model.
Embodiment
The utility model is described in further detail for explanation and embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the floating rotating edge-trimming cutter structure of a kind of stamping die, including upper die and lower die, it is described on Mould includes upper mold seat 9, spring 1, upper mold trimming cutter block 2, swivel bearing 3 and rotation trimming cutter block 4, the upper mold trimming cutter block 2 It is fixed on the upper mold seat 9, the rotation trimming cutter block 4 with the swivel bearing 3 and the upper mold seat 9 rotation by connecting Connect, the spring 1 is arranged on the left end of the rotation trimming cutter block 4, and the right end of the rotation trimming cutter block 4 is close to the upper mold Trimming cutter block 2, the lower die include placing restrictions on block 5, lower die trimming cutter block 6, lower die waste knife 7 and die holder 8, it is described place restrictions on block 5, Lower die trimming cutter block 6, lower die waste knife 7 are separately fixed on the die holder 8, described to place restrictions on block 5 and the rotation edge-trimming cutter The left end of block 4 is engaged, and the lower die trimming cutter block 6 is engaged with the upper mold trimming cutter block 2, the lower die waste knife 7 with The right end of the rotation trimming cutter block 4 is engaged.
As shown in Figure 1 to Figure 3, the left end of the rotation trimming cutter block 4 is equipped with places restrictions on 5 matched protrusion of block with described Portion.
A kind of floating rotating edge-trimming cutter structure of stamping die provided by the utility model, it is during trimming:Upper mold Move downward, drive upper mold trimming cutter block 2 to move downward and complete part entirety waste material trimming.Upper mold continues to move downward, lower die Block 5 of placing restrictions on start contact rotation trimming cutter block 4 and force the 4 upward motion compresses spring 1 of left end of rotation trimming cutter block, due to rotation Turn to be fixed in upper mold trimming cutter block 2 by swivel bearing 3 among trimming cutter block 4, by leverage, the entirety above cut is given up Material is progressively compressed by the right end of rotation trimming cutter block 4 and lower die waste knife 7 until cutting off.After the whole trimmings of upper mold completion back up Move back, the spring 1 compressed also progressively restores, so as to promote 4 homing of rotation trimming cutter block, completes a trimming, answers The cyclic process of position.
A kind of floating rotating edge-trimming cutter structure of stamping die provided by the utility model has the following advantages:
(1)The problems such as raising part trimming quality, the friendship knife for eliminating part trimming have some setbacks, burr.
(2)Surface quality of workpieces is improved, the iron filings produced by reducing part trimming, reduce and made because iron filings are brought into mould Into piece surface weigh wounded, sags and crests problem.
(3)Improve part production efficiency, reduce production when caused by mould tipping, part burr reason online mould Maintenance time.
(4)Intensity and the service life of mould cutter block cutting edge are improved, reduces the debug time of part trimming cut burr.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded To belong to the scope of protection of the utility model.
