Abstract
The invention discloses a screw die initial punching device, comprising an initial punching device body. The middle part of the initial punching device body is provided with a round through hole; on one of the end parts of the initial punching device body is provided with a cavity; the cavity is communicated with the round through hole and formed by a circular-arc hole of the cavity and a cone hole of the cavity, wherein the circular-arc hole of the cavity is disposed on the end of the initial punching device body, and the cone hole of the cavity is disposed on the rear part of the circular-arc hole of the cavity; the cavity has a length h of 3.25-3.35mm; the circular-arc hole of the cavity has a diameter D of 7.0-7.1mm; and the cone hole of the cavity has a conicity of 10 degrees and a diameter d of 4.4mm. Due to the adoption of the screw die initial punching device, the processing precision of the product can be controlled conveniently, the production efficiency is improved effectively, the service life of the product is prolonged significantly, the qualification rate and the output efficiency of the product are improved, the production cost is lowered, and the quality of the product is well guaranteed.
Description
Technical field
The present invention relates to a kind of screw mfg. moulding die, relate in particular to a kind of screw mold and just dash.
Background technology
As a kind of standard component of fixed connection, be seen everywhere in screw Modern Production and the life.Just dash as one of cold forging die necessary in the screw production industry, it is mainly used in the predeformation of material, and the control accuracy of its size will satisfy the requirement in the screw production process.Existing mould is just high towards repair rate, and production efficiency is low, and service life is short, and product quality can't strict guarantee.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of production efficiency high, and the screw mold of long service life just dashes.
In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: a kind of screw mold just dashes, and towards body, this just is provided with manhole towards the centre at the beginning of comprising; Saidly just dash wherein that an end is provided with die cavity, this die cavity is communicated with said manhole.
In order to improve the machining accuracy of product, further, said die cavity constitutes with the die cavity taper hole that is arranged on die cavity circular hole rear portion by being arranged on first die cavity circular hole towards the termination.
Further, said die cavity length h is 3.25-3.35mm.
Further, said die cavity circular hole diameter D is 7.0-7.1mm.
Further, the tapering C of said die cavity taper hole is 10 °, and the taper hole diameter d is 4.4mm.
Compared with prior art, usefulness of the present invention is: the first punch die tool of this screw is convenient to control the machining accuracy of product, has effectively improved production efficiency; The significant prolongation in service life of product; Qualification rate and output efficiency improve, and reduce production costs, and guarantee product quality well.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is that a kind of screw mold of the present invention is just towards structural representation;
Fig. 2 is that a kind of screw mold of the present invention is just towards the side structure cutaway view;
Fig. 3 is the partial enlarged drawing of A among Fig. 2.
Among the figure: 1, just dash; 2, manhole; 3, die cavity circular hole; 4, die cavity taper hole.
The specific embodiment:
Describe the present invention below in conjunction with the accompanying drawing and the specific embodiment:
Fig. 1, Fig. 2 and a kind of screw mold shown in Figure 3 just dash, and comprise just dashing 1 body, and this is provided with manhole 2 in the middle of just dashing 1, said just dash 1 wherein an end be provided with die cavity, this die cavity is communicated with said manhole 2; Said die cavity constitutes by being arranged on die cavity circular hole 3 that just dashes 1 termination and the die cavity taper hole 4 that is arranged on die cavity circular hole 3 rear portions, and in order to improve machining accuracy, said die cavity length h is 3.25-3.35mm, and die cavity circular hole 3 diameter D are 7.0-7.1mm; The tapering C of said die cavity taper hole 4 is 10 °, and the taper hole diameter d is 4.4mm.
The first punch die tool of this screw is convenient to control the machining accuracy of product, has effectively improved production efficiency, the significant prolongation in service life of product, and qualification rate and output efficiency improve, and reduce production costs, and guarantee product quality well.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
