Abstract
The utility model discloses a high-precision positioning cold-extrusion die, which comprises an upper die holder, a lower die holder, a discharge plate and a positioning mechanism, wherein a fixing plate and a die shank are arranged on the upper die holder, and an upper punch is arranged in the fixing plate; one end of the die shank is connected with the upper punch, and a female groove is arranged on the lower die holder; the positioning mechanism and the discharge plate are arranged between the upper punch and the die, and a stamping through hole with the same size as the upper punch is formed in the discharge plate; the positioning mechanism comprises a positioning sleeve and a positioning rod, and a plurality of positioning bearings are arranged on the inner wall of the positioning sleeve; the positioning rod sequentially penetrates through the upper die holder and the fixing plate and is arranged in the positioning sleeve. The high-precision positioning cold extrusion die provided by the utility model has the advantages that the high-precision positioning is realized in the stamping process, the situation that the stamping angle of a workpiece does not meet the standard due to excessive stamping of the punch is avoided, the production efficiency is improved, the production cost is reduced, and the reliability of continuous work is ensured.
Description
Technical field
The utility model relates to a kind of cold extrusion die, refers more particularly to a kind of cold extrusion die of hi-Fix.
Background technology
In modern times manufacture and processing industry, fine-edge blanking occupies considerable status, fine-edge blanking need to carry out on precise punching machine, because essence punching is very high to the required precision of precise punching machine, its cost is also very high, so Fine punching die frame is installed on common punch press to carry out fine-edge blanking and is just generally applied, because Fine punching die frame can not carry out punching and the blanking of multistation on the different parts of the larger sheet material of same, therefore not only make efficiency low, and production process is long, also exist the utilization rate of material low, the problem that cost is high, while scraping workpiece on drift, may make the local deformation of workpiece and produce mismachining tolerance, and equipment investment and frock clamp cost higher, machining accuracy is difficult to ensure.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is just to provide in order to address the above problem, the cold extrusion die of hi-Fix easy to use.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises upper bolster, die shoe, stripper and detent mechanism, on described upper bolster, be provided with fixed head and die shank, in described fixed head, be provided with upper punch, one end of described die shank is connected with described upper punch, on described die shoe, be provided with die, described detent mechanism and described stripper are arranged between described upper punch and described die, described stripper is provided with the punching press through hole identical with described upper punch size, described detent mechanism comprises positioning sleeve and backstay, the inwall of described positioning sleeve is provided with multiple location bearings, described backstay passes successively described upper bolster and described fixed head and is arranged in described positioning sleeve.
Particularly, the lower end of described die is provided with material discharging rod.
Further, between described upper bolster and described die shoe, be provided with guide pillar guide pin bushing.
Particularly, described die shoe is connected by set bolt with described die.
The beneficial effects of the utility model are:
The utility model can be realized and in punching course, realize hi-Fix, prevents that drift from, because excessive punching press causes workpiece punching press angle not meet standard, enhancing productivity, and has saved production cost, ensures the reliability of continuous operation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-upper bolster, 2-guide pillar guide pin bushing, 3-backstay, 4-upper punch, 5-stripper, 6-die shoe, 7-location bearing, 8-positioning sleeve, 9-material discharging rod, 10-die, 11-punching press through hole, 12-set bolt, 13-fixed head.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises upper bolster 1, die shoe 6, stripper 5 and detent mechanism, on described upper bolster 1, be provided with fixed head 13 and die shank, in fixed head 13, be provided with upper punch 4, one end of die shank is connected with upper punch 4, on die shoe 1, be provided with die 10, detent mechanism and stripper 5 are arranged between upper punch 4 and die 10, stripper 5 is provided with the punching press through hole 11 identical with upper punch 4 sizes, detent mechanism comprises positioning sleeve 8 and backstay 3, the inwall of positioning sleeve 8 is provided with multiple location bearings 7, backstay 3 passes successively upper bolster 1 and fixed head 13 and is arranged in positioning sleeve 8.
The lower end of die 10 is provided with material discharging rod 9, between upper bolster 1 and die shoe 6, is provided with guide pillar guide pin bushing 2, and die shoe 6 is connected by set bolt 12 with die 10.
Operation principle of the present utility model is as follows:
When workpiece is put into after die, upper punch 4 moves downward workpiece is carried out to punching press, backstay 3 is successively through upper bolster 1 and fixed head 13, play the guiding function to upper punch 4, prevent that drift is because excessive punching press causes workpiece punching press angle not meet standard, and the multiple location bearings 7 that are arranged in positioning sleeve 8 can ensure the descending time delay axial-movement of backstay, can realize and in punching course, realize hi-Fix and enhance productivity, save production cost, ensured the reliability of continuous operation.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should be included in protection domain of the present utility model.
