Abstract

The utility model relates to an upsetting-stamping composite mould. The upsetting-stamping composite mould is characterized in that a convex mould positioning block and a concave mould positioning block are rectangular and outwards extend towards one side, wherein guide pins are fixedly connected on four corners of the concave mould positioning block; the four corners of the convex mould positioning block are sleeved on the guide pins and are aligned with the concave mould positioning block; the extending parts at one sides of the convex mould positioning block and the concave mould positioning block are movably connected by a blank dowel pin; a concave mould sleeve is arranged on the rectangular center part of the concave mould positioning block; a concave mould core is placed in the concave mould sleeve; the concave mould core is cylindrical; the diameter of the top end of the concave mould core is bigger than that of the lower end of the concave mould core; a groove is formed on the center of the upper surface of the concave mould core; a polyurethane spring is sleeved on the concave mould core from the lower end; the concave mould core is limited with the concave mould sleeve by the polyurethane spring; a convex mould is arranged on the rectangular centre part of the convex mould positioning block; and a bulge on the bottom end of the convex mould is aligned to the groove on the concave mould core. According to the upsetting-stamping composite mould, the blank is positioned with the positioning concave mould and the positioning convex mould of the mould, so that the hole stamping-flanging precision is ensured, and therefore, the defect that the hole stamping-flanging side is broken and inconsistent in height after being stamped and flanged is radically overcome, and the trial-manufacturing quality and trial-manufacturing level of the stamping parts are effectively improved.

Description

Composite die is rushed in upsetting
Technical field
The utility model relates to a kind of upsetting and rushes composite die, belongs to stamping parts Quick-forming field.
Background technology
Usually for stamping parts, the threaded hole flanging that rushes appears in trial-manufacturing process, because screw thread is M6 or M8, the thread Pilot hole that punching is turned over is Φ 5 or Φ 6.8, adopting in the past simple and easy mold to rush turns over, the situation that flange occurs highly and variable thickness causes of rushing hole flanging owing to not leading, cause punching to be turned over and occur breaking afterwards, perhaps the thick attenuate of local material is serious, and postorder can't tapping.
The utility model content
The purpose of this utility model is to provide a kind of upsetting and rushes composite die, the form of mutually locating between its location by blank and mould, punch-die, guaranteed to rush the precision of hole flanging, fundamentally overcome and rush the hole flanging limit and break and rush and turn over the defectives such as rear height is inconsistent, effectively raise quality and the level of such stamping parts trial-production.
the technical solution of the utility model is achieved in that upsetting rushes composite die, by the blank alignment pin, punch, the punch locating piece, the die locating piece, polyurethane spring, the die core, the die sleeve, guide finger forms, it is characterized in that: the punch locating piece, the die locating piece is rectangle one epitaxial lateral overgrowth and stretches, four corners of die locating piece are fixedly connected with guide finger, four corners of punch locating piece are enclosed within on guide finger aligns with the die locating piece that aligns, the punch locating piece, the part that die locating piece one side is extended is flexibly connected by the blank alignment pin, die locating piece rectangular centre is partly the die sleeve, place the die core in the die sleeve, the die core is column, top end diameter is larger than the below, die core upper surface center has groove, polyurethane spring is enclosed within on the die core from the lower end, the die core is spacing by polyurethane spring and die sleeve, punch locating piece rectangular centre is partly punch, the punch bottom has projection to aim at groove on the die core of below.
Good effect of the present utility model is that it is reliable and stable at work, and blank has reliable location, when punching is turned over, upsetting squeeze is carried out at the flange position, reaches drawing requirement, compares with formal mould simultaneously, has greatly saved ducts starting cost and cycle.

Specific embodiments
[0009] below in conjunction with accompanying drawing, the technical program is further detailed: composite die is rushed in upsetting, by blank alignment pin 1, punch 2, punch locating piece 3, die locating piece 4, polyurethane spring 5, die core 6, die sleeve 7, guide finger 8 forms, it is characterized in that: punch locating piece 3, die locating piece 4 is rectangle one epitaxial lateral overgrowth and stretches, four corners of die locating piece 4 are fixedly connected with guide finger 8, four corners of punch locating piece 3 are enclosed within on guide finger 8 aligns with the die locating piece 4 that aligns, punch locating piece 3, the part that die locating piece 4 one sides are extended is flexibly connected by blank alignment pin 1, die locating piece 4 rectangular centre are partly die sleeve 7, the interior placement die of die sleeve 7 core 6, die core 6 is column, top end diameter is larger than the below, die core 6 upper surface centers have groove 9, polyurethane spring 5 is enclosed within on die core 6 from the lower end, die core 6 is spacing by polyurethane spring 5 and die sleeve 7, punch locating piece 3 rectangular centre are partly punch 2, punch 2 bottoms have projection 10 to aim at groove 9 on the die core 6 of below.
Shown in Fig. 1,3, first polyurethane spring 5 is enclosed within and puts into die sleeve 7 on die core 6, be positioned on 100T press workbench, then with the blank of laser cutting as on 4 die locating pieces; Simultaneously punch 2 and punch locating piece 3 are welded together, utilize guide finger 8 and blank alignment pin 1 to position, handle press and carry out punching press, complete upsetting highly the time and break through journey until punch core 6 bottoms and die sleeve 7 bottom surfaces are in one.
