Abstract
The utility model discloses a special plunger chip for a punching of a lower platen of a lower support of an automobile damper, which can be used for effectively avoiding a crack at a corner and ensuring the stability of product quality. The special plunger chip consists of three integral punch die units; the outer end surface of each punch die unit comprises a main arc surface, and each side of the main arc surface is respectively connected with a linear plane by an inward-concave transition arc surface and an outward-convex transition arc surface. In the special plunger chip, as each side of the main arc surface on the outer end surface of each punch die unit is respectively connected with the linear plane by the inward-concave transition arc surface and the outward-convex transition arc surface, the crack at the corner can be effectively avoided, the stability of the production quality is ensured, and the product yield is improved.
Description
Technical field
The utility model relates to a kind of automobile absorber undersetting lower platen punching special punch.
Background technology
In the process that automobile product updates, automobile absorber undersetting lower platen lower platen need carry out again Design and Machining to adapt to the requirement of Product Renewal.Newly-designed automobile absorber undersetting lower platen lower platen need carry out flange and be processed into finished product in process to the intermediate member that punching is processed into.At present, the sketch map of the employed drift of punching processing is as shown in Figure 1, is made up of three punch die unit 1 of one, and the outer face of each punch die unit comprises arc surface 2, and the both sides of arc surface are connected with straight line plane 3 respectively.Because the product difficulty of processing is big, arc surface and straight line plane corner very easily crack in the turn-up process, cause product quality to go wrong, and percent defective is high, and quality stability is low.
The utility model content
The utility model is in order to overcome weak point of the prior art, a kind of automobile absorber undersetting lower platen punching special punch to be provided, crackle occurs to avoid corner effectively, guaranteeing the stability of product quality.
The utility model is realized through following technical proposals:
A kind of automobile absorber undersetting lower platen punching special punch; Punch die unit by three one is formed; It is characterized in that; The outer face of each punch die unit comprises main arc surface, and every side of said main arc surface is connected with the straight line plane with cambered outwards transition circle cambered surface through the transition circle cambered surface that concaves respectively.
Wherein, main arc surface is 3: 1: 1 with the diameter ratio of transition circle cambered surface that concaves and cambered outwards transition circle cambered surface.
The utlity model has following technique effect:
The automobile absorber undersetting lower platen punching special punch of the utility model; Every side of main arc surface is connected with the straight line plane with cambered outwards transition circle cambered surface through the transition circle cambered surface that concaves respectively in the outer face of each punch die unit; Can avoid corner crackle to occur effectively; Guarantee the stability of product quality, improved the finished product rate.
Description of drawings
Fig. 1 is the employed drift sketch map of prior art;
Fig. 2 is the sketch map of the utility model automobile absorber undersetting lower platen punching special punch.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Fig. 2 is the sketch map of the utility model automobile absorber undersetting lower platen punching special punch; Punch die unit 4 by three one is formed; The outer face of each punch die unit comprises main arc surface 5, and every side of said main arc surface 5 is connected with straight line plane 8 with cambered outwards transition circle cambered surface 7 through the transition circle cambered surface 6 that concaves respectively.Wherein, main arc surface 5 is 3: 1: 1 with the diameter ratio of transition circle cambered surface that concaves 6 and cambered outwards transition circle cambered surface 7.The transition circle cambered surface that concaves is connected with the straight line plane with cambered outwards transition circle cambered surface, can avoid corner crackle to occur effectively, improves the finished product rate.
Claims (2)
1. automobile absorber undersetting lower platen punching special punch; Punch die unit by three one is formed; It is characterized in that; The outer face of each punch die unit comprises main arc surface, and every side of said main arc surface is connected with the straight line plane with cambered outwards transition circle cambered surface through the transition circle cambered surface that concaves respectively.
2. automobile absorber undersetting lower platen punching special punch according to claim 1 is characterized in that main arc surface is 3: 1: 1 with the diameter ratio of transition circle cambered surface that concaves and cambered outwards transition circle cambered surface.
