Description

Part bending equipment capable of being adjusted at multiple angles for machining

Technical Field

The invention belongs to the technical field of part bending equipment, and particularly relates to part bending equipment capable of being adjusted in multiple angles for machining.

Background

Bending, i.e. deformation by the action of forces which are the result of the resulting force, is the presence of a plurality of forces during the manufacturing process. The bending of the workpiece includes both cold bending and hot bending. Bending can be divided into press bending, roll bending and stretch bending according to the process characteristics. Press bending is the most common bending method, and the most used equipment is a general mechanical press or a hydraulic press, and a special bending press is also used. The common roll bending equipment is a plate bending machine, and a three-roller plate bending machine continuously bends a plate blank according to the principle that three points determine a circle. The three-roller plate bending machine is provided with two driving rollers (fixed) and a pressing roller (adjustable). The relative distance between the lower pressing roller and the driving roller can be changed by adjusting the upper and lower positions of the lower pressing roller. When the plate is bent, the plate is arranged between the driving roller and the pressing roller, and the driving roller rotates in a positive and negative direction in a switching way, so that the plate reciprocates. The press roller is adjusted to be gradually pressed down, so that the plate can be bent into a cylindrical surface with required curvature, a conical surface and a hyperboloid with smaller curvature. One end of the press roller can be lifted, so that the workpiece can be conveniently unloaded. In addition, the plate bending machine with four rollers is used for bending a thick plate cylinder, and the plate bending machine with more than four rollers is used for gradually bending a plate into a complex profile by using a plurality of pairs of rollers. Bending parts with higher precision requirement, larger length and curvature radius requirement and smaller transverse dimension requirement can be subjected to stretch bending on a special stretch bending machine. During stretch bending, the whole thickness of the plate is under the action of tensile stress, so that only the plate is elongated and deformed, the deformation caused by rebound after unloading is small, and the precision is easy to ensure.

For example, application No.: the invention of CN201910920555.0 discloses a multi-dimensional stereo bending apparatus, comprising: base, mould mount table, rocking arm, first flexible drive arrangement, the flexible drive arrangement of second, the flexible drive arrangement of third, horizontal slide and vertical slide, the drive of rocking arm is carried out in first flexible drive arrangement pin joint between rocking arm and base rear portion, horizontal slide sets up on the rocking arm, be provided with the floating frame that carries out swing back and forth regulation through the flexible drive arrangement of second in the vertical slide, swing span about being provided with in the floating frame, be provided with the guide bar of directional mould mount table top in the swing span about, the guide bar end is provided with rotary mechanism, the last chuck that sets up of rotary mechanism.
