Description
Technical Field
The utility model relates to a mould field, concretely relates to support shaping burring mould after punching a hole.
Background
The scheme aims at the support, as shown in figure 3, a part of mounting holes need to be machined in the later stage, the structure of the part is not detailed, the scheme is characterized in that after the support is forged, the technology of punching a middle lightening hole is needed to be described, due to the structural characteristics of a product, burrs can be pulled out of the lightening hole along one circle of the punching direction, as shown in figure 3, the specific position of the burrs is above the lightening hole of the support, a certain gradient is formed around the lightening hole due to punching, the burrs in the original process need to be manually polished in the later process, the efficiency is low (15 s/piece), deformation caused by punching the lightening hole needs to be shaped on a shaping die, and therefore the problems that the integral machining period of the workpiece is long, the production efficiency is low and the like are caused.
In view of the problem that above-mentioned prior art exists, the utility model discloses combine many years' design of relevant field and experience in use, assist too strong professional knowledge, the design has made a support and has punched a hole back plastic burring mould, overcomes above-mentioned defect.
Disclosure of Invention
To the problem that exists among the prior art, the utility model provides a pair of support plastic burring mould after punching a hole realizes plastic burring combined machining through the mould with the support after punching a hole, has improved production efficiency.
In order to realize the purpose, the utility model discloses a technical scheme as follows: a shaping and deburring die for punched supports comprises an upper die and a lower die, wherein a lower appearance positioning groove is formed in the lower die and is matched with the appearance of the bottom of a support, a boss is arranged in the lower appearance positioning groove and is matched with the appearance of a lightening hole of the support, and the boss is provided with a guide slope;
the upper die is provided with an upper appearance positioning groove, the upper appearance positioning groove is matched with the appearance of the upper part of the support, a burr ring cutter is arranged in the upper appearance positioning groove, the end part of the burr ring cutter can deform slightly, and a polishing layer is arranged outside the burr ring cutter ring.
Preferably, the size of an inner ring of the burr ring cutter is slightly larger than the size of the outline of the lightening hole, and the size of the inner ring of the burr ring cutter when the burr ring cutter deforms towards the inside of the ring is smaller than the size of the outline of the lightening hole.
The utility model discloses an useful part lies in:
1. the utility model discloses burr ring-cutting sword with the support contact back, can be along the structure of support itself to the intra-annular deformation of burr ring-cutting sword, thereby make burr ring-cutting sword tip exert horizontal power to the burr, cut off the burr, because the direction slope on the boss, make there is certain clearance between lightening hole top and the boss top, then do not influence burr ring-cutting sword tip to intra-annular deformation, and simultaneously, the burr still can get into this clearance, can not drop to influence the plastic on the support because of the burr, thereby kill two birds with one stone, the burr has been got rid of on the one hand, on the other hand has accomplished plastic work.
2. The utility model discloses burr ring cutter ring is equipped with the layer of polishing outward and can moves down along with last mould and polish to the burr position after the cutting to improve surface quality.
Drawings
FIG. 1 is a schematic structural view of a lower die of a shaping and deburring die after punching a support;
FIG. 2 is a schematic structural diagram of an upper die of a shaping and deburring die after punching of a support;
fig. 3 is a schematic structural view of the support.
In the figure: 1-lower die, 2-lower outline positioning groove, 3-boss, 4-guiding slope, 5-upper die, 6-upper outline positioning groove, 7-burr ring cutter, 8-polishing layer, 100-support, 101-lightening hole and 102-burr.
Detailed Description
In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 2, the die comprises an upper die 5 and a lower die 1, wherein a lower contour positioning groove 2 is formed in the lower die 1 and is matched with the bottom contour of a support 100, a boss 3 is arranged in the lower contour positioning groove 2, the boss 3 is matched with a lightening hole 101 of the support 100 in contour, and the boss 3 is provided with a guide slope 4 for facilitating the placement of the support 100;
an upper appearance positioning groove 6 is formed in the upper die 5, the upper appearance positioning groove 6 is matched with the appearance of the upper portion of the support 100, a burr ring cutter 7 is arranged in the upper appearance positioning groove 6, the size of an inner ring of the burr ring cutter 7 is slightly larger than the appearance size of the lightening hole 101, the end portion of the burr ring cutter 7 can deform slightly, and the size of the inner ring when the burr ring cutter 7 deforms towards the inner ring is smaller than the appearance size of the lightening hole 101.
When the upper die 5 descends, the burr ring-cutting knife 7 deforms in a ring towards the burr ring-cutting knife 7 along a punched gradient structure of the support 100 after contacting with the support 100, so that the end part of the burr ring-cutting knife 7 exerts a transverse force on the burr 102 to cut off the burr 102, and because the guide gradient 4 on the boss 3 ensures that a certain gap exists between the upper part of the lightening hole 101 and the top part of the boss 3, the deformation of the end part of the burr ring-cutting knife 7 towards the ring is not influenced, meanwhile, the burr 102 also enters the gap, the shaping cannot be influenced due to the fact that the burr 102 drops on the support 100, so that two purposes are achieved by one action, the burr 102 is removed on the one hand, and the shaping work is completed on the other hand.
The utility model discloses it is preferable to be equipped with the layer 8 of polishing outside burr circular cutting knife 7 rings, and the layer 8 of polishing can be along with last mould 5 moves down and polishes the burr 102 position after the cutting to improve surface quality.
It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes, modifications and/or alterations to the present invention may be made by those skilled in the art after reading the technical disclosure of the present invention, and all such equivalents may fall within the scope of the present invention as defined by the appended claims.
