Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 to 6: the embodiment discloses auto-parts stamping die with positive side handing over cutter, including upper die base 1, die holder 2, be equipped with guider between upper die base 1, the die holder 2, upper die base 1 includes upper die shell 11 and connects in the drive block of upper die shell 11 lower surface, and die holder 2 includes lower mould shell 21 and sets up in lower mould benevolence 211, a plurality of elastic column 4 of lower mould shell 21.
The lower die holder 2 of drive block is connected the face and is equipped with stamping device and sliding guide device, and stamping device is including connecting in proper order in the punching press board of drive block 91, cushion, two 92 of punching press board, and punching press board 91, cushion, two 92 of punching press board still are equipped with towards tool bit 93, that is to say that towards tool bit 93 wears at punching press board 91, cushion, inside of two 92 of punching press board, and its tool bit is used for connecting the preformed hole of lower mould benevolence 211.
The sliding guide device comprises an upper V-shaped sliding block 94 and a lower V-shaped sliding block 212 used for connecting the upper V-shaped sliding block 94, and the upper V-shaped sliding block 94 and the lower V-shaped sliding block 212 are respectively connected with the driving block and the lower mold core 211.
Specifically, the number and the layout of the driving blocks can be set according to specific product shapes, for the automobile stamping part of the embodiment, the driving blocks comprise a first driving block 5 and two second driving blocks 6, the two second driving blocks 6 are distributed in a V shape, and the first driving block 5 is arranged opposite to the two second driving blocks 6.
The fixing mode of the driving block is as follows: the driving block is connected with an upper shuttering 11 through a connecting screw rod 8, and an elastic pull rod 10 is arranged between the connecting screw rod 8 and the driving block. The elastic rod 10 can be any one of the prior art, and has a certain elasticity, so that the driving block can slide along the lower surface of the upper mold shell 11 to a certain extent.
The upper surface and the side of this embodiment driving block all are equipped with antifriction plate 7, and antifriction plate 7 of driving block upper surface mainly plays the effect that reduces friction, and antifriction plate 7 of side is used for playing the effect of fixed driving block, is equivalent to making a arch of formation of driving block, slides in upper die shell 11.
Specifically, the guiding device of the embodiment includes sliding grooves 31 disposed at two ends of the lower mold shell 21 and a plurality of guiding pillars 32 disposed in the sliding grooves 31, both the sliding grooves 31 and the guiding pillars 32 are connected to the upper mold shell 11, and the side portions of the sliding grooves 31 are also provided with the wear-resistant plates 7. The wear plate 7 is preferably fixed from a lubricating material and has good wear reduction properties and high strength, such as nylon blocks.
In the case of punching, a discharge plate 33 is further provided in the lower die case 21 of the present embodiment, which is expected to be large. The two discharging plates 33 are disposed higher inside and directly under the lower mold insert 211, so that the material can be naturally discharged by gravity.
In order to avoid the driving block falling off from the lower mold shell 21, the driving block of the present embodiment is slidably connected to the lower mold shell 21 through a connecting hook 51. The connecting hook head 51 is used for hooking the wear plate 7 at the side of the sliding chute 31.
In order to avoid hard collision between the upper die holder 1 and the lower die holder 2, a buffer block 41 is further disposed on a connecting surface of the upper die holder 1 of the lower die shell 21 in this embodiment.
During working, a blank is placed under the lower die core 211, the upper die base 1 is operated to descend along the guide device, the driving block firstly bends and stretches the blank, and in the initial stage, the blank deformation is small, so that the driving block cannot slide relative to the upper die shell 11 (namely, the two V-shaped sliding blocks are relatively static), the compression amount of the elastic pad between the first stamping plate 91 and the second stamping plate 92 is not large, the stamping tool bit 93 does not extend, and the whole stamping device is only equivalent to a block.
When the blank is extruded to a certain degree, the two V-shaped sliding blocks slide relatively, the elastic pull rod 10 is stretched, and the driving block plays a certain drawing role on the blank, so that the forming of a product is facilitated. When the upper die holder 1 continues to descend, the driving block descends to the bottommost end and contacts the lower limit of the upper die shell 11, the two V-shaped sliding blocks do not slide relatively, and the whole drawing and stamping process is completed.
And then, a punching process is carried out, the elastic pad between the first punching plate 91 and the second punching plate 92 is extruded, the punching cutter head 93 extends out to complete punching, and the excess material is discharged through the discharge plate 33.
The utility model discloses can accomplish the punching press to the product, draw and the operation of punching a hole through a mould, because the drive block can the sliding guide device be certain range's slip along 11 lower surfaces of upper die shell for the stamping process can draw and extrude the product, avoids damaging the blank, promotes the yields, can also accomplish the operation of punching a hole of positive side handing over sword after drawing and extrusion are accomplished. The discharge plate 33 can avoid the phenomenon of anticipating the jamming.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
