Problems solved by technology

[0004] In the traditional tube bundle bending forming process, most of the heat exchangers to be bent are manually transported to the bending die in the main machine of the bending machine through the input end of the main machine of the bending machine, and then bent and formed. The work efficiency of the method is low and the labor intensity is high
[0005] In order to solve the above problems, the applicant has created a related feeding mechanism before. For details, please refer to the announcement number CN 104690182 B. The patent name is an invention patent for a feeding component of a bending machine. The technical solution is disclosed The feeding component of the bending machine carries the workpiece to be bent (such as a heat exchanger to be bent) on the loading platform and is pushed by the material shifting mechanism to realize automatic transportation, which can reduce labor intensity and improve work efficiency. Efficiency; and the feeding platform is driven up or down by the feeding lifting mechanism to adjust the height of the feeding platform, so that the feeding platform can be accurately docked with the main machine of the external bending machine, so that the feeding component is connected to the main machine of the external bending machine The entire process of conveying the workpiece to be bent and receiving the material from the main machine of the external bending machine is carried out stably and smoothly, which solves the problem that the loading platform cannot be accurately docked with the main machine of the external bending machine due to the existence of various errors such as assembly errors ; In addition, the material loading platform can still normally push the workpieces to be bent under different height positions by using the independent material shifting mechanism and feeding and conveying components, but this structure uses the pushing method to push the workpieces to be bent Entering into the main machine of the bending machine, during the pushing process of the workpiece to b

Description

Technical field [0001] The present invention belongs to the field of heat exchanger bending machine, and more particularly to a feeding mechanism of a heat exchanger bending machine and a bending machine to which it is applied. Background technique [0002] Tielding heat exchanger serves a wide range of applications in the refrigeration industry as a compact heat exchanger. The forming process of the heat exchanger mainly has the following three forming processes: tube bending forming (forming a U-tube), mechanical transflation tube forming (realizing tube-mold connection), tube bundle bending formation (formation of a G-type heat exchanger ). The tube bundle is one of the key processes of the heat exchanger forming, which has an important impact on the performance of the heat exchanger. [0003] When the tube bundle is formed, the heat exchanger is first delivered to a predetermined position, so that the portion you want to be curved is close to the bending mode (roller) having ...
