Problems solved by technology

In the existing process, in order to obtain high-performance multi-layer heat exchange, the single-layer heat exchangers are bent separately and then assembled. The manufacturing process is complicated and the production efficiency is low.
There are also some processing techniques that are completed on a bending machine, but the processing is not precise, and the qualified rate of the heat exchanger produced is low.

Abstract

The invention relates to a bending machine capable of bending layer by layer, which comprises a frame; a rotating roller and a rotating roller driving mechanism which drives the rotating roller to rotate are arranged on the frame; an upper pressure plate which rotates with the rotating roller is arranged on the rotating roller; a lower pressure plate is arranged below the upper pressure plate; a clamping control device for controlling the lower pressure plate and the upper pressure to clamp heat exchangers with spacing is arranged between the lower pressure plate and the upper pressure plate; the technical key points are as follows: a lifting mechanism is arranged on the frame; a lifting platform is arranged on the lifting mechanism; a movable bending following platform which can slide on the lifting platform and can be inserted into the adjacent two layers of radiating tubes of the heat exchangers and a pushing mechanism which pushes the movable bending following platform to move are arranged on the lifting platform; and a positioning mechanism which positions the heat exchangers is arranged on one side of the lower pressure plate on the frame. The bending machine can bend precisely, has a simple process and can bend a plurality of layers of heat exchangers layer by layer.

Description

【Technical field】 [0001] The invention relates to a bending machine. 【Background technique】 [0002] As a compact heat exchanger, the tube-fin multilayer heat exchanger has been widely used in the refrigeration industry, and the multilayer bending forming process of the heat exchanger is a key link that affects the performance of the heat exchanger. In the existing process, in order to obtain high-performance multi-layer heat exchange, the single-layer heat exchangers are bent separately and then assembled. The manufacturing process is complicated and the production efficiency is low. There are also some processing techniques that are completed on a bending machine, but the processing is not precise, and the qualified rate of the heat exchanger produced is low. 【Content of invention】 [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a bending machine capable of bending multilayer heat exchangers with precise bending ...
