Double-node bending equipment for machining automobile parts and process using method of bending equipment

Abstract

The invention discloses double-node bending equipment for machining automobile parts. The equipment comprises a body frame of a double-layer structure, an arc-shaped guide rail arranged on the top layer of the body frame, a power device, and a pushing and pressing device which is matched and connected with the bottom end of the power device, is arranged from the top layer to the bottom layer of the body frame and can extend and retract. The bottom layer of the body frame is provided with a strip-shaped containing groove for containing part of a sectional material, bent portions close to the two ends of the strip-shaped containing groove and located on the same side, and first propelling devices and second propelling devices which sequentially propel the sectional material in two directionscorrespondingly. The end of the sectional material is pushed to be bent towards the side where the bent portions are located through first push rods arranged on the first propelling devices, the second propelling devices and the bent portions are arranged on the same side, and the end of the sectional material is pushed inwards from the two ends of the strip-shaped containing groove through two second push rods arranged on the second propelling devices. By means of the double-node bending equipment, double-node synchronous bending is achieved, the bending treatment process is simplified, andrigidity damage to the sectional material in the bending process is effectively reduced.

Description

technical field [0001] The invention relates to the field of profile processing and the field of processing auto parts, in particular to a bending device for processing auto parts with two nodes and a process using method thereof. Background technique [0002] At present, the curved strip profiles are used by all walks of life, especially in the field of machinery and auto parts processing. Auto parts processing is the unit that constitutes the overall processing of auto parts and the products that serve the processing of auto parts. There are many types of auto parts. With the With the improvement of people's living standards, people consume more and more cars, and the market for auto parts is getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. During processing, usually a thin plate with a small thickness is processed first, and then the thin plate is cut into a plate body according to the required size, and then the plate bod...

Problems solved by technology

The punch of the traditional bending machine moves in a straight line, that is, the movement track of the punch is perpendicular to the plane of the plate. When the punch bends and deforms the plate, the punch also needs to slide relative to the concave surface of the plate for extrusion. Or withdraw, but nowadays the requirements for the diversity of the plate body and the performance of the processed profiles are getting higher and higher, and the traditional processing technology cannot meet the diverse profile processing, nor can it achieve the effect of saving time and effort, and profiles often appear in the follow-up Process defects such as unevenness and scratches on the surface increase the consumption of subsequent investment. In order to simplify the process steps and subsequent surface treatment of profiles, improve processing efficiency
