Abstract
It the utility model is related to a kind of new forging die buckle structure, including upper die and lower die, the bottom centre of described upper mould is provided with lock cavity plate, the top center of lower mould is provided with lock punch-pin, the lock cavity plate is merged in corresponding distribution and by clamping system with lock punch-pin, described lock cavity plate, the side for latching punch-pin are formed by straight shelves and diagonal cleat integrated combination, and the length of the straight shelves is 17MM, and are in 90 ° of angle shapes with the contact edges of upper die and lower die；The side of the diagonal cleat and upper die and lower die is in 15 ° of angle shapes；For described lock cavity plate with lock punch-pin in matched moulds, the matched moulds thickness △ between both is 1MM；The beneficial effects of the utility model are：Make mismatch amount stable, the control of mismatch amount is improved the quality of forging in certain scope, so as to reduce machining allowance, is made the part dynamic balance performance in power transmission shaft more preferable.
Description
Technical field
The utility model belongs to technical field of mold, more particularly to a kind of new forging die buckle structure.
Background technology
The advantages of lock is while improving forging quality, moreover it is possible to plays a part of guiding and reduces the die adjustment time,
The species of lock is varied.Existing universal four buckle structures design of forging die as shown in Figure 1, 2, the size 30*30 of lock；Forging
The upper and lower die clearance of mould is △=0.2~0.5mm；Angle is 5 degree, and lock depth is 35mm.The upper and lower mould matched moulds of existing structure
When, influenceed by factors such as the thickness of matched moulds and personnel's hand operations, △ controls are uneven, cause mismatch amount unstable.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the prior art, and provides a kind of mismatch amount stabilization, and machine adds
The new forging die buckle structure of work accurate positioning.
The purpose of this utility model is completed by following technical solution, including upper die and lower die, described upper mould
Bottom centre is provided with lock cavity plate, and the top center of lower mould is provided with lock punch-pin, and the lock cavity plate is with lock punch-pin in corresponding
It is distributed and is merged by clamping system, described lock cavity plate, latches the side of punch-pin by straight shelves and diagonal cleat one group
Conjunction forms, and the length of the straight shelves is 17MM, and is in 90 ° of angle shapes with the contact edges of upper die and lower die；The diagonal cleat and upper die and lower die
Side be in 15 ° of angle shapes.
Preferably, described lock cavity plate, with latching punch-pin in matched moulds, the matched moulds thickness △ between both is
1MM。
The beneficial effects of the utility model are：Make mismatch amount stable, the control of mismatch amount is improved forging in certain scope
The quality of part, so as to reduce machining allowance, make the part dynamic balance performance in power transmission shaft more preferable.
Brief description of the drawings
Fig. 1 is existing forging die lock main structure diagram.
Fig. 2 is existing forging die lock overlooking the structure diagram.
Fig. 3 is forging die lock main structure diagram of the present utility model.
Label in accompanying drawing is respectively：1st, upper mould；2nd, lower mould；3rd, straight shelves；4th, diagonal cleat；5th, latch；11st, cavity plate is latched；21、
Latch punch-pin.
Embodiment
Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in Figure 3, the utility model includes upper mould
1st, lower mould 2, the bottom centre of described upper mould 1 are provided with lock cavity plate 11, and the top center of lower mould 2 is provided with lock punch-pin 21, should
Lock cavity plate 11 is merged in corresponding distribution and by clamping system with lock punch-pin 21, it is characterised in that：Described
Lock cavity plate 11, the side of lock punch-pin 21 are formed by straight shelves 3 and the integrated combination of diagonal cleat 4, and the length of the straight shelves 3 is 17MM, and
Contact edge with upper mould 1, lower mould 2 is in 90 ° of angle shapes；Mismatch when straight shelves 3 are to ensure that the thickness of matched moulds is between 2.5~4mm
Amount is consistent.The diagonal cleat 4 is in 15 ° of angle shapes with upper mould 1, the side of lower mould 2；The total depth of lock 5 is 35MM.
For described lock cavity plate 11 with lock punch-pin 21 in matched moulds, the matched moulds thickness △ between both is 1MM.
The utility model is not limited to above-mentioned embodiment, makees any change no matter being formed in its shape or material, all
It is to use structure design provided by the utility model, is all a kind of deformation of the present utility model, is considered as new in this practicality
Within type protection domain.
