Punching and trimming die for automobile ABS (anti-skid brake system) supports

Abstract

The invention provides a punching and trimming die for automobile ABS (anti-skid brake system) supports. The punching and trimming die comprises an upper die block and a lower die block. The upper die block comprises an upper die plate and an upper fixing plate, and the upper fixing plate is disposed under the upper die plate through an upper padding plate. The lower die block comprises a lower die plate, a lower padding plate is disposed on the lower die plate, a female die frame is disposed on the lower padding plate, and die assembling is performed through a sliding guide post component between the upper die plate and the lower die plate. The punching and trimming die is characterized by further comprising three punching component sets and one trimming component, each punching component comprises a punching punch disposed in the upper fixing plate and an female die arranged in the female die frame and facing the punching punch, the trimming component comprises a trimming punch disposed in the upper fixing plate and a trilling female die disposed in the female die frame and facing the position of the trimming punch. By the punching and trimming die, punching processing of a circular positioning hole, a convex circular hole and a bending surface circular hole and trimming processing of transverse planes toward upper sides can be performed on workpieces in one-time punching, processing efficiency can be greatly improved, and processing quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of stamping processing of auto parts, in particular to a punching and trimming die for the lower bracket of the ABS system of an automobile.

[0002] A lower bracket for an automobile ABS system, the structure of which is shown in figure 1 , figure 2 and image 3 , the bracket plane includes a transverse plane 25 and a longitudinal plane 26, the transverse plane 25 and the longitudinal plane 26 are connected by a curved plane 27, three downward projections 28 are evenly distributed along the transverse axis on the transverse plane 25, and the transverse plane is opened There is a circular positioning hole 29, a downward circular boss 30 is arranged on the curved plane 27, a circular hole 31 is arranged on the surface of the circular boss 30, and a downward elongated protrusion 32 is arranged on the longitudinal plane, In addition, it is also provided with a downward flanging 33 and an upward continuous bending surface 34. There is also a circular hole 35 on the bending surface 34. Its structure is complicated. In the past, it needs to be processed step by step, and the blanking is performed first. The punching and positioning processing of the round hole of the boss, and then the bending forming, the embossing of the elongated protrusion, the subsequent downward flanging, the embossing of the protrusion on the horizontal axis, and finally the punching Hole trimming processing is complex, and each step of processing needs to be equipped with a corresponding mold. Not only is the processing efficiency low, but the cost of the mold is high, and multiple mold stamping processes require multiple positioning of the workpiece, resulting in low machining accuracy of the workpiece
