Numerical control punching machine for longitudinal beam of automobile

Abstract

The invention discloses a numerical control punching machine for a longitudinal beam of an automobile, and relates to a molding machine special for large plates. A host machine comprises a three-column closed A-type body, a sliding block, a sliding block driving device and a workbench; the workbench is provided with a floating supporting device; the sliding block is provided with a pressing device; a discharging device comprises a discharging base, a blanking bracket and a blanking trolley; a feeding device comprises a feeding base, a beam moveably connected among the feeding base, the workbench and the discharging base, a loading trolley, a loading bracket, a lifting device, a gripping mechanism fixedly connected on two sides of the top surface of the beam, and a centering device arranged on the loading bracket; the loading bracket is provided with a roller set, the centering device is arranged on two sides of the roller set; the gripping mechanism is arranged on the two sides of the roller set and positioned between the centering device and the workbench in the feeding direction; and a jaw of the gripping mechanism is slightly higher than the top surface of the floating supporting device. The numerical control punching machine has the advantages of high automation degree, low manufacturing lost of corresponding mold, and high reliability and adaptability.

Description

technical field [0001] The invention relates to a special forming machine tool for large sheet metal, in particular to a fully automatic numerical control punching machine tool for longitudinal beams of automobiles. Background technique [0002] The chassis of a car is an important part of a car, but due to changes in models and parts such as engines, it will have a great impact on chassis manufacturers. At present, large-scale automobile chassis manufacturers mainly rely on large-tonnage presses for one-time stamping and forming. Small and medium-sized automobile chassis manufacturers can only rely on radial drilling machines to draw lines and profiling. The former needs to develop large molds, which makes the cost higher; the latter The efficiency is low and the degree of automation is low. Contents of the invention [0003] Aiming at the above problems, the present invention provides a numerically controlled punching machine tool for automobile longitudinal beams that ...
