Abstract

The utility model relates to the folding base mould in a kind of retainer forming technology, and comprise punch and briquetting, described briquetting is arranged on punch upper end, and acts on downwards on punch; Described punch comprises base, be located at the frustum of a cone on base and circumference is distributed in some boss on the frustum of a cone conical surface, forms the guide-localization groove of retainer workpiece between two adjacent institute boss.Its beneficial effect is: the new processing technology having coordinated retainer well, disposable the completing of the taper work in new process is enable to roll over base, and by arranging trapezoid block on punch hypotenuse, make workpiece fixing in mould location, thus make easy and simple to handle, efficiency is high, the machining accuracy needed for simultaneously ensureing.

Description

Folding base mould in a kind of retainer forming technology
Technical field
The utility model relates to the workpiece folding base technology in retainer moulding process, particularly relates to the folding base mould in a kind of retainer forming technology.
Background technology
There is such defect in the processing method of retainer, first material is cut into circle, and discarded leftover pieces are many, and make waste of material serious, utilization rate of raw materials is low, only has 12-25%; Need be realized the structure of design by machining, not only increase power consumption but also increase material consumption, also increase the holding time of manufacture course of products simultaneously, make production efficiency low, cost of manufacture is high.
If the improvement carried out for raw material cutting shape and provide a kind of new processing technology, coordinate with regard to needing corresponding mould.Such as first be cut into by raw material rectangular-shaped, then rectangle material carried out circle circle and the stretching conical surface, this can make the leftover pieces discarded greatly reduce, and in above-mentioned processing method, needs to carry out the process of folding base to taper work.
Utility model content
The purpose of this utility model is to provide in a kind of machining process new at retainer, carries out to retainer workpiece the matching die rolling over base.
For achieving the above object, the folding base mould in retainer forming technology described in the utility model, comprise punch and briquetting, described briquetting is arranged on punch upper end, and acts on downwards on punch; Described punch comprises base, be located at the frustum of a cone on base and circumference is distributed in some boss on the frustum of a cone conical surface, forms the guide-localization groove of retainer workpiece between two adjacent institute boss.
A preferred boss plan of establishment is trapezoid block.
In order to ensure to distribute to frustum of a cone upper end to the location of workpiece and guiding ladder-shaped block downwards.
A preferred briquetting plan of establishment is a cylinder.
The beneficial effect of the utility model folding base mould is: the new processing technology having coordinated retainer well, disposable the completing of the taper work in new process is enable to roll over base, and by arranging trapezoid block on punch hypotenuse, make workpiece fixing in mould location, thus make easy and simple to handle, efficiency is high, the machining accuracy needed for simultaneously ensureing.
Accompanying drawing explanation
Fig. 1 is the structural representation of folding base die punch.
Fig. 2 is the top view of mold base shown in Fig. 1.
Fig. 3 is the generalized section of workpiece when being in initial position.
Fig. 4 is the generalized section that briquetting presses down in process.
In figure: 1 is the frustum of a cone, 2 is trapezoid blocks, and 3 is bases, and 4 is workpiece, and 5 is briquettings.
Detailed description of the invention
The utility model is the mould for carrying out flanging to the retainer workpiece gone out through a kind of brand-new processes, new work by taper and on the conical surface retainer workpiece in uniform hole carry out flanging processing, the retainer needed for formation by folding base of the present utility model mould.Below in conjunction with a concrete folding base mould, the utility model is described further.
As Fig. 1,2, this mould is primarily of briquetting 5 and punch composition, and punch comprises base 3 and the frustum of a cone 1.The frustum of a cone 1 arranges on the base 3, and the conical surface on it is evenly equipped with some boss 2, and boss 2 is arranged downwards from the cone element direction, edge, upper end of the frustum of a cone 3.Boss 2 is trapezoid block, forms workpiece guide-localization groove between two adjacent trapezoid blocks 2, and for the location of conduplication side workpiece, the hole on the workpiece conical surface is embedded on boss 2, and when to workpiece flanging, workpiece can carry out certain movement along above-mentioned guide-localization groove opposing mold.
Briquetting 5 is cylindricality, the top of punch is coaxially arranged on punch, the briquetting 5 of the present embodiment is cylindrical, when carrying out flanging to needing the retainer workpiece of flanging, briquetting 5, under the hydraulic jack of correspondence drives, acts on punch downwards, see Fig. 3, by the upper end Edge Bend higher than punch, see Fig. 4, form retainer.
