Automobile back longitudinal beam end plate forming die

Abstract

The invention discloses an automobile back longitudinal beam end plate forming die which belongs to the field of die equipment. The automobile back longitudinal beam end plate forming die comprises a lower die base, a lower die backing plate, a guide post, a lower die, an upper die and an upper die fixing plate, wherein the lower die base, the lower die backing plate, the guide post, the lower die, the upper die and the upper die fixing plate are arranged in sequence from bottom to top; profile surfaces of the lower die include a horizontal surface and a curved surface, wherein the horizontal surface and the curved surface are mutually and smoothly connected, a discharge plate mounting hole is formed in the horizontal surface, and a conical bulge is formed on the curved surface; the lower die and the lower die backing plate are connected by a pin, and the upper die and the upper die fixing plate are connected by a pin; the shape of the upper die is matched with that of the lower die, and discharge rods are arranged in the middle of the upper die. The automobile back longitudinal beam end plate forming die has the advantages of high punching efficiency, good manufacturing precision and stronger adaptability and can be used for a long time, the cost is reduced, the lower die made of alloy steel is adopted, and the shape of the lower die is consistent with that of a back longitudinal beam end plate.

Description

technical field [0001] The invention belongs to the field of mold equipment, and more specifically relates to an automobile rear longitudinal beam end plate forming mold. Background technique [0002] The frame of the car is mainly composed of longitudinal beams and beams. The cross-section of the longitudinal beams of the frame is mostly I-shaped, which is composed of upper and lower end flanges welded to the web. Under the conditions of use, the longitudinal beam as the main component of the frame bears various complex loads from the road and loading, and the strength, stiffness and life of the frame longitudinal beam are very important in the overall design of the car. Therefore, the rear longitudinal beam end plate as the medium connecting the longitudinal beam and the vehicle body must reach a certain service strength, and the production of the existing rear longitudinal beam end plate is time-consuming and laborious, and the high cost is not conducive to long-term deve...
