Abstract
The utility model discloses a one-point second punch sleeve of a screw die, which comprises a body, a forming blind hole, an inner through hole, a projecting point and a step. The body is cylindrical. The forming blind hole and the inner through hole are equipped inside the body along the central axis of the body. A transitional chamfer is equipped between the forming blind hole and the inner through hole. The step is equipped on one end of the body. The projecting point is equipped on one end face of the body. The projecting point is an electric spark forming projecting point. By adopting the above-mentioned technical scheme, the one-point second punch sleeve has the beneficial effects of high product qualified rate, processing error decrease, processing precision control, effective production efficiency increase, service lifetime prolongation, processing time reduction and personnel cost decrease.
Description
Technical field
The utility model relates to a kind of screw mold, is specifically related to a kind of screw mold one two and dashes cover.
Background technology
As a kind of standard component of fixed connection, be seen everywhere in screw Modern Production and the life.A bit as one of cold forging die commonly used in the screw production industry, its main moulding (preformed) is in screw head for wolfram steel, and the control accuracy of its size will satisfy the national standard of screw product.Existing screw mold wolfram steel one two dashes the cover lathes that adopt more and processes, and main technological process is: 1). and the machining blanks raw material is cylindric barred body; 2). the car endoporus in cylindric bar center; 3). with the disconnected profile of cylindric bar car, length; 4). car moulding salient point; 5). the polishing salient point.Above-mentioned processing process is complicated, owing to rely on manually processing more, so processing is consuming time, waste of manpower, the difficulty control relatively of the stepped hole portion size of nest plate, percent defective is high, and production efficiency is low, and two dash the weak point in service life of cover, and product quality can't strict guarantee.
Need a kind of screw mold one two to dash cover product percent of pass height for this reason, reduce mismachining tolerance, the control machining accuracy is effectively enhanced productivity, and increases the service life, and can save process time and personnel cost simultaneously.
The utility model content
For solving the problems of the technologies described above, the purpose of the utility model is to provide a kind of product percent of pass high, reduces mismachining tolerance; The control machining accuracy; Effectively enhance productivity, increase the service life, the screw mold one two that can save process time and personnel cost simultaneously dashes cover.
For achieving the above object, the technical scheme of the utility model is following: a kind of screw mold one two dashes cover, comprises body, blind hole, inner via hole, salient point and step; Said body is cylindric; Said blind hole and said inner via hole are arranged in the said body along said body central axis, are provided with the transition chamfering between said blind hole and the said inner via hole, and an end of said body is provided with said step; One end face of said body is provided with salient point, and said salient point is the edm forming salient point.
Preferably, the other end of said body is provided with fillet.
Preferably, said a kind of screw mold one two is processed for wolfram steel or chromium steel towards cover.
Adopt the beneficial effect of present technique scheme to be: product percent of pass is high, reduces mismachining tolerance, and the control machining accuracy is effectively enhanced productivity, and increases the service life, and can save process time and personnel cost simultaneously.
Description of drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment technology; To do to introduce simply to the accompanying drawing of required use in the embodiment technical description below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The structural representation that Fig. 1 implements for the utility model.
The numeral corresponding component title represented among the figure with letter:
1. body 2. blind holes 3. inner via holes 4. salient points 5. steps.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of embodiment of the utility model, a kind of screw mold one two dashes cover; Comprise body 1, blind hole 2, inner via hole 3, salient point 4 and step 5, body 1 is cylindric, and blind hole 2 is arranged in the body 1 along body 1 central axis with inner via hole 3; Be provided with the transition chamfering between blind hole 2 and the inner via hole 3, an end of body 1 is provided with step 5, and an end face of body 1 is provided with salient point 4; Salient point 4 is the edm forming salient point, and the other end of body 1 is provided with fillet.A kind of screw mold one two is processed for wolfram steel towards cover in the present embodiment.
The processing technology that a kind of screw mold one two of the utility model dashes cover, this processing technology comprises:
⑴ the Vehicle Processing of blank raw material is cylindric bar, middle preformed blind hole;
⑵ profile, the length of cylindric bar of grinding machine attrition process and step;
⑶ in the center of cylindric bar punch processing inner via hole;
⑷ spark machined moulding salient point;
⑸ polishing processing salient point.
The utility model adopts high-precision numerical control machining center to produce electrode; Utilize high accuracy electric discharge machine processing screw mold one two to dash cover then; Dash the technology of overlapping with respect to traditional machined into screw mold one two; Not only be convenient to control processing dimension, and improved dimensional accuracy of products, reduced disqualification rate; The utility model adopts electrical discharge machining process, has reduced the influence of human factor to product quality, has reduced machining period and personnel attrition; The utility model can be processed typical products in mass production simultaneously, has not only significantly promoted working (machining) efficiency, reduce production costs, and significantly prolongs the service life of product.
All the other are identical with embodiment 1, and difference is that a kind of screw mold one two is processed for chromium steel towards cover in the present embodiment.
Adopt the beneficial effect of present technique scheme to be: product percent of pass is high, reduces mismachining tolerance, and the control machining accuracy is effectively enhanced productivity, and increases the service life, and can save process time and personnel cost simultaneously.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
