Description
Technical field
The utility model relates to field of machine punching, is specifically related to a kind of punch of punching press resistance to cracking squash type boss and is provided with the diel of this punch.
Background technology
In field of machining, punching press is application technique widely, in the processing of many metallic articles or on-metallic article, all needs to use various Sheet Metal Forming Technology.But some are made and requires higher boss product punching press, during conventional punch punching press, can not well realize punching press effect.Please refer to accompanying drawing 1, accompanying drawing 1 is about the punch of boss punching press and die in prior art, and this punch makes simple, only can need obtain flinging head through simple grinding.This punch is continuous extrded material in punching course, makes material deforms thus forms boss structure.But when the straight body size of boss structure is larger, punch extrudes more, when boss is deformed to a certain degree arrival plastic deformation, the toughness of material reduces greatly.Be main stress point as marked t1 part in Fig. 1, in the process of punch extruding, it is thinning that the t1 part on boss constantly reduces material, then easily come off herein, then under this condition, the size of the straight section of the boss structure of punching press is just far not by far up to the mark, and the quality of boss structure is affected.And be also subject in stronger impact at the punching course convex mould of this boss, the relevant position of punch is also because of long-term punching press, and unbalance stress, punch is damaged, and makes troubles to production.
About punching course convex mould damage situations, also some are had to study in prior art: Chinese utility model patent CN 201768910 U discloses a kind of Integral forming punch mold, the punch occurred in process of production to solve prior art in this patent comes unstuck the situation such as loosening, disclose following technical scheme: fixed part and connecting portion and punch portion link into an integrated entity, be connected in one by punch portion and connecting portion, making compact conformation need not use glue solid punch, avoiding punch loosening because coming unstuck.But the mould described in this patent is applicable to magnetic material, due to material particularity but with the punch of particular design, this technical scheme is unsuitable for the diel of punching press lathe.
Chinese utility model patent application CN 103599994 A discloses a kind of punch and has the diel of this punch, the sidewall of the drift of this punch and the installation portion of punch holder has inclined-plane, the incline direction on described inclined-plane is outward-dipping on the direction that extends to the termination of described installation portion from the position that described installation portion is connected with pressing part, then in punching course, drift realizes locating by inclined-plane and punch holder, and punch holder is necessarily cushioned at inclined-plane place the pressure of drift.This technical scheme is skillfully constructed, but be applicable to that punch connects by drift and punch holder two parts, and the pressure that drift bears only is considered in this design, does not consider the pressure suffered by product to be punched, is not suitable for the situation that the utility model is mentioned.
Utility model content
For above-mentioned deficiency of the prior art, main purpose of the present utility model is to provide a kind of punch for punching press resistance to cracking squash type boss, this punch structure is through adjustment, obtain dispersed in punching course with boss contact site stressed, stress does not concentrate on same position, thus improves the service life of punch; Utilize the boss structure of this punch structure punching press good, ratio of briquetting is high, and yields is high, and can not come off the situations such as fracture in punching course.
For achieving the above object, disclosed in the utility model, technical scheme is: a kind of punch for punching press resistance to cracking squash type boss, described punch comprise one connect rush and drift, described one end rushing handle is located at by described drift, described punching is being cylinder, the tapered frustum cone structure of described drift, described drift and punching are provided with junction to hang takes on structure.
Preferably, described drift also comprises a ledge structure, and institute's ledge structure to be located at below described conical round table structure and to be connected and rushes handle.
Preferably, the height of described ledge structure is between 0.1mm-0.5mm.
Preferably, the ledge structure place plane below the sidewall of the drift of described conical round table structure and drift is an angle, and the described angle number of degrees are between 30 °-50 °.
The utility model discloses a kind of diel being provided with above-mentioned punch, described diel comprises patrix frame plate, counterdie frame plate, described patrix frame plate has upper mould fixed plate, upper mould fixed plate is provided with punch, described counterdie frame plate is provided with concave template, described concave template is provided with die, and described punch is corresponding with described die; Described die is cylindrical, and one end of described die is provided with nib, and the edge of described nib is provided with step, and the extension of described step and described punch is takeed on structure and matched.
Preferably, the height of the step at the edge of described nib is between 0.1mm-0.3mm.
The utility model hangs shoulder structure by creationary having set up on punch, make in punching course, punch is in the process of punching press, hang shoulder structure by the material of sheet material that is in contact with it upwardly, make to be positioned at above the material hanging shoulder structure division flow to, thus making the t1 value of boss in punching course relatively become large, thickness increases herein, thus makes the t1 place not easy fracture of boss; And in traditional boss punching course, usually cause punching press failure because of the t1 place fracture of boss.Further, the power that extension described in the utility model shoulder structure makes the easily broken place of boss punching course be subject to also can relative distribution, greatly reduces the probability of the fracture in boss punching course.Thus under ensureing the prerequisite of boss not easy fracture, the boss straight section height stamped out also can correspondingly increase, and meets need of production, improve the stamping technology about boss in prior art.
The beneficial effects of the utility model are: punch structure of the present utility model is reasonable in design, can effectively punching press resistance to cracking squash type boss structure, and this punch structure avoids the damage that punch punching press position causes because of long-term punching press unbalance stress, extend the service life of punch.
