Abstract
The utility model discloses a die for manufacturing an automobile rear wheel bearing blanking cap. The die for manufacturing the automobile rear wheel bearing blanking cap comprises an upper die plate and a lower die plate, wherein the upper die plate and the lower die plate are matched with each other. The upper die plate is provided with an upper half shear die, an upper reverse redrawing die set, an upper leveling die, an upper blanking die and an upper scrap cutting die from left to right in sequence. The lower die plate is provided with a lower half shear die, a lower reverse redrawing die set, a lower leveling die, a lower blanking die and a lower scrap cutting die which correspond to all the die blocks of the upper die plate. According to the die for manufacturing the automobile rear wheel bearing blanking cap, the upper half shear die is added, material straps are sheared in advance through the upper half shear die, and due to the fact that only half shearing is carried out, products are still on the material straps, subsequent stretching, leveling, blanking and other operation can be carried out. Meanwhile, stress of stretching and leveling can be offset through sheared cuts, wrinkling and deformation of the material straps are avoided accordingly, the unevenness of the peripheries of the products is also reduced, and production quality and production efficiency are improved.
Description
Technical field
The utility model relates to auto-parts manufacturing equipment field, particularly a kind of mould of preparing automobile back wheel bearing blanking cover.
Background technology
Existing automobile back wheel bearing blanking cover mould and processing mode normally stretch on a rectangular material strip, then shaping is cut into a three-dimensional circular automobile back wheel bearing blanking cover, because the profile of automobile back wheel bearing blanking cover is rounded, in the process of stretching and shaping, easily there is the wrinkling problem of material strip, affect production efficiency, serious even impact is produced; Meanwhile, shear just also out-of-flatness of finished product periphery of automobile back wheel bearing blanking cover out, finished product fraction defective is high, also needs further rear processing to process for the wrinkling serious first finished product of periphery, and this has also increased production technology and cost virtually.
Utility model content
The purpose of this utility model is for existing automobile back wheel bearing blanking cover mould material strip and the easily wrinkling problem of first finished product in use of preparing, and a kind of mould of architecture advances is provided.
To achieve these goals, the utility model provides a kind of mould of preparing automobile back wheel bearing blanking cover, comprise the cope match-plate pattern and the lower bolster that cooperatively interact, cope match-plate pattern be from left to right sequentially provided with first cut-off-die, upper reverse-drawing module, upper leveling mould, upper blanking die and on cut waste material mould; On lower bolster, be provided with second cut-off-die corresponding with first cut-off-die on cope match-plate pattern, with the corresponding lower reverse-drawing module of described upper reverse-drawing module on cope match-plate pattern, with the corresponding lower leveling mould of upper leveling mould on cope match-plate pattern, with the corresponding dropping material mould of upper blanking die on cope match-plate pattern and with cope match-plate pattern on cut the corresponding incision waste material mould of waste material mould.
Preferably, upper reverse-drawing module comprises two upper reverse-drawing modules, descends accordingly on reverse-drawing module and also has two lower reverse-drawing modules, in order to material strip is carried out to twice prestretched.
Therefore, the utility model beneficial effect is: the mould of preparing automobile back wheel bearing blanking cover of the present utility model improves on the basis of existing mould, concrete, has increased first cut-off-die.In advance material strip is sheared by this half cut-off-die, owing to only having sheared half, product remains on material strip, therefore can carry out the operations such as follow-up stretching, leveling, blanking; Meanwhile, owing to having carried out semishearing, the stress of stretching and leveling disperses by this sheared edge, and when having avoided stretching and having flattened, the wrinkling problem of material strip, has also reduced the irregular problem of first finished product periphery, has improved the quality of production and production efficiency.

Fig. 2 is the structural representation of lower bolster in embodiment of the present utility model;
Fig. 3 is the structural representation of processing material strip in embodiment of the present utility model.
Description of reference numerals is as follows:
Cope match-plate pattern 1, lower bolster 2, first cut-off-die 11, upper leveling mould 13, upper blanking die 14, on cut waste material mould 15, second cut-off-die 21, lower leveling mould 23, dropping material mould 24, incision waste material mould 25, upper reverse- drawing module 121 and 122, lower reverse- drawing module 221 and 222.
Detailed description of the invention
In order to make auditor can further understand the purpose of this utility model, existing attached preferred embodiment is to be described in detail as follows, and the present embodiment is only for the technical solution of the utility model is described, and non-limiting the utility model.
The automobile back wheel bearing blanking cover mould of preparing of the present utility model, comprise the cope match-plate pattern 1 and the lower bolster 2 that cooperatively interact, cope match-plate pattern as shown in Figure 1, lower bolster as shown in Figure 2, cope match-plate pattern 1 be from left to right sequentially provided with first cut-off-die 11, upper reverse-drawing module, upper leveling mould 13, upper blanking die 14 and on cut waste material mould 15; On lower bolster 2, be provided with second cut-off-die 21 corresponding with first cut-off-die 11 on cope match-plate pattern 1, with the corresponding lower reverse-drawing module of described upper reverse-drawing module on cope match-plate pattern 1, with the corresponding lower leveling mould 23 of upper leveling mould 13 on cope match-plate pattern 1, with the corresponding dropping material mould 24 of upper blanking die 14 on cope match-plate pattern 1 and with cope match-plate pattern 1 on cut the corresponding incision waste material mould 25 of waste material mould 15.Upper reverse-drawing module comprises two upper reverse- drawing modules 121 and 122, descends accordingly on reverse-drawing module and also has two lower reverse- drawing modules 221 and 222, in order to material strip is carried out to twice prestretched.
When use, material strip as shown in Figure 3, enters mould of the present utility model under the driving force of pay-off, after punching and multi-drawing sizing, is prepared into satisfactory automobile back wheel bearing blanking cover.An improvement of mould of the present utility model and existing mould maximum is, before stretching leveling, carry out in advance semishearing operation, namely increase by one and half cut-off-dies, the otch that utilization is cut off is offset the stress of the leveling that stretches, thereby avoid the wrinkling distortion of material strip, also reduced the out-of-flatness of product periphery.
Need statement, above-mentioned utility model content and detailed description of the invention are intended to prove the practical application of technical scheme that the utility model provides, and should not be construed as the restriction to the utility model protection domain.Those skilled in the art are in spirit of the present utility model and principle, when doing various amendments, be equal to and replace or improve.Protection domain of the present utility model is as the criterion with appended claims.
