Problems solved by technology

[0003] 1) The part has a bending angle and extends to the outside for a long time, and the shaking of the material belt during the feeding process causes the edge of the material to be unstable
[0004] 2) The size of the flange height of the part is bad, and the height of the flange is offset
[0005] And this problem cannot be solved by modifying the edge line of the material and adjusting the positioning method; at present, the flanging height of the parts is unstable, and only continuous online maintenance and debugging are available during production, which causes great troubles for production and delivery

Embodiment Construction

[0020] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as Figure 1-4 As shown, a progressive stamping die for a radiator bracket includes an upper mold base 1 and a lower mold base 2. The upper mold base 1 is provided with a mounting seat 3 in the feeding section, and the mounting base 3 corresponds to both sides of the raw material plate. A number of guide blocks 4 are respectively provided, and two outer end punches 5 for stamping a pair of outer end through holes opposite to the set workpiece, and positioning punches for punching the middle positioning hole on the raw material plate are arranged in turn on the mounting seat 3 along the feeding direction. Head 6 and a pair of inner end punches 7 for stamping the inner end through holes of the workpiece, a pair of middle section cutter blocks 8 for punching the middle section of the adjacent workpiece connection part along the feedin...

Abstract

The invention discloses a progressive stamping die for a radiator support, wherein the progressive stamping die is stable in part flanging size and high in yield. According to the die, workpieces aresymmetrically punched and formed from a raw material plate until a product is cut off and sent out at a last work station; due to the fact that an upper pressing plate is provided with a plurality ofpositioning pins which are used for positioning workpieces and matched with positioning punches in position, and a discharging base is provided with a plurality of positioning pins which are used forpositioning the workpieces and matched with the positioning punches in position, a plate can be accurately positioned on all work stations, and thus the processing precision of all the work stations is guaranteed. Besides, ribbing and line pressing inserts are additionally arranged on an upper die and a lower die in the previous procedure of bending, ribbing and reinforcing are conducted on the product in advance, the situation that the height of the product is not stable in the later procedure of bending and flanging is avoided, and the processing efficiency and the product quality are greatly improved.

Description

technical field [0001] The invention relates to a stamping die, in particular to a progressive stamping die for a radiator bracket. Background technique [0002] The radiator bracket is a roughly Z-shaped three-stage bending product, and the product requires 4.5mm flanging on both sides. However, the existing continuous die stamping production has the following problems: [0003] 1) The part has a bending angle and extends to the outside for a long time, and the shaking of the material belt during the feeding process causes the edge of the material to be unstable. [0004] 2) The flange height of the parts is poor, and the flange height is offset. [0005] And this problem cannot be solved by modifying the edge line of the material and adjusting the positioning method; at present, the flanging height of the part is unstable, and the production can only be continuously repaired and debugged online, which causes great troubles to production and delivery.
