Problems solved by technology

[0002] The traditional method of forming saddle-shaped curved steel plate parts is heating and pressing. The cost of mold opening is high and the processing cycle is long. The steel needs to be heated at high temperature, which affects the material properties, consumes a lot of energy, and does not meet the requirements of environmental protection.
At the same time, a certain margin needs to be reserved when typesetting, and the material loss is large

Embodiment 1

[0035] A cold-bending forming machine for a saddle-shaped curved panel, including a curved panel 1, a support rod 2 and a pipe bender 3, such as Figure 1 ~ Figure 3 As shown, the specific structure is:

[0036] Curved plate 1 such as figure 1 As shown: the cross section of the curved plate 1 is arc-shaped, and the bus bars of the curved plate 1 are straight lines parallel to each other;

[0037] Such as figure 2 As shown: the support rods 2 are sequentially arranged at the opening of the arc-shaped plate 1, and the two ends of the support rods 2 are respectively welded and fixed on one side of the arc-shaped plate 1, and each support rod 2 is parallel to each other. The middle support rod 2 bears tensile stress, so the connection weld between the support rod 2 and the arc-shaped plate 1 must be firm;

[0038] The pipe bender 3 comprises a support 31, a support 32, a driver 33 and a pipe bending die 34. A support 32 is respectively fixed on both sides of the support 31, th...

Abstract

The invention relates to the field of straight-line bending metal plates, in particular to a cold bend forming machine for saddle-shaped curved plates and a using method thereof. The cold bend formingmachine for the saddle-shaped curved plates comprises an arc-shaped plate (1) and is characterized in that supporting rods (2) and a pipe bending machine (3) are further included, the supporting rods(2) are sequentially arranged at the opened position of the arc-shaped plate (1), and the two ends of the supporting rods (2) are fixed to one side edge of the arc-shaped plate (1); and the two endsof the arc-shaped plate (1) are erected on supports (32) of the pipe bending machine (3) correspondingly, and the convex cambered surface of the arc-shaped plate (1) is attached to a pipe bending diehead (34) of the pipe bending machine (3). The using method of the cold bend forming machine for the saddle-shaped curved plates is characterized by sequentially executing the following steps of (1) making the arc-shaped plate, (2) erecting supports and (3) making saddle-shaped curved surfaces. According to the cold bend forming machine for the saddle-shaped curved plates and the using method thereof, raw materials are saved, the production rate is increased, machining precision is high and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of bending metal plates along a straight line, in particular to a cold bending forming machine for a saddle-shaped curved panel and a method for using the same. Background technique [0002] The traditional method of forming saddle-shaped curved steel plate parts is heating and pressing, which has high cost of mold opening and long processing cycle. The steel needs to be heated at high temperature, which affects the material properties, consumes a lot of energy, and does not meet the requirements of environmental protection. At the same time, a certain margin needs to be reserved during typesetting, and the material loss is large. Contents of the invention [0003] In order to overcome the defects of the prior art and provide a sheet material processing method that saves raw materials, improves productivity, has high processing precision, and reduces energy consumption, the invention discloses a cold-bending forming...
