An intelligent numerical control stepless control bending machine with improved structure

Abstract

The invention discloses an intelligent numerical control stepless control bending machine with an improved structure, which includes a pneumatic lifting base, and the top of the pneumatic lifting base is equidistantly equipped with a plurality of lower mold clamping mechanisms that can be rolled and connected with the lower template, and Both ends of the top of the pneumatic lifting base are equipped with end limit mechanisms that can be rolled and connected with the lower formwork. The intelligent numerical control stepless control bending machine with this improved structure is different from the existing technology and ensures effective installation and fixation of the lower formwork. At the same time, during the bending process of the aluminum guide rail of the automobile sunroof, it can effectively avoid the situation that the lower template is forcibly stretched or squeezed, thereby effectively improving the service life of the lower template, thereby effectively controlling the cost of equipment and equipment, and avoiding frequent Disassembly and assembly will affect the efficiency of normal production and processing.

Description

technical field [0001] The invention relates to the technical field of bending and forming devices for metal profiles, in particular to an intelligent numerical control stepless control bending machine with an improved structure. Background technique [0002] At present, metal profiles with a certain amount of bending are widely used in production and life, especially in the manufacture of aircraft and automobiles. In order to obtain metal profiles with a predetermined amount of bending, it is necessary to bend the metal profiles For example, the aluminum material applied to the guide rail of the automobile sunroof needs to be bent and formed during processing. When the bending equipment for the aluminum guide rail of the automobile sunroof in the prior art is used in work, most of the workpieces are directly placed on the lower mold of the bending equipment. On, and through the press fit of the upper mold to complete the bending, and in the bending process, the lower mold b...

Problems solved by technology

[0003] However, when the lower formwork in the prior art is installed, the clamping block is mostly displaced by the clamping cylinder, and the clamping base is used to forcibly squeeze the lower formwork, so as to realize the installation and fixation of the lower formwork, although the lower formwork It is made of nylon material with a certain rebound rate, but when the clamping cylinder is too tight, although the installation of the lower formwork is relatively stable, but the lower formwork is in the middle section between each clamping cylinder, it will be in the lower formwork It is forced to stretch during bending processing. Even if the stretching deformation is small, it will seriously affect the service life of the lower template during continuous processing. When the clamping cylinder is too loose, although it can effectively avoid the lower template However, this will cause the lower template to be displaced relative to the clamping top block due to the influence of extrusion and bending during the bending process, and when it is reset after the bending is completed, it will lose the limit of extrusion, so that it cannot It is easy to reset, and it will be forced to squeeze and shrink during the next bending and extrusion process, which will also seriously affect its service life, and then the lower template needs to be replaced frequently, which increases the use cost of the equipment, and the frequent disassembly process It will also greatly affect the efficiency of normal production and processing. For this reason, we propose an intelligent numerical control stepless control bending machine with improved structure
