Automatic pipe penetrating and guiding universal device for large multi-hole-number heat exchanger

Abstract

The invention relates to the technical field of an air conditioner heat exchanger and particularly relates to an automatic pipe penetrating and guiding universal device for a large multi-hole-number heat exchanger. The device comprises a base, a supporting piece arranged on the base and a top plate arranged on the supporting piece, and further comprises a guide frame, a first guide mechanism and asecond guide mechanism, wherein the first guide mechanism and the second guide mechanism are arranged on the guide frame and used for guiding copper pipes, the guide frame is movably connected with the base, and the guide frame is movably connected with the top plate. The device is advantaged in that a guiding structure is divided into two parts, the two guide mechanisms are each provided with afirst guiding assembly and a second guiding assembly, pipe penetrating guiding operation of the large multi-hole-number heat exchanger can be carried out, labor intensity of workers is relieved, guiding precision during pipe penetrating is guaranteed, moreover, pipe penetrating efficiency is improved, and production cost is reduced; besides, a third connecting plate is arranged in the middle of the guide frame, so moving stability of the upper guide plate and the lower guide plate is further improved, and closing precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of production of air-conditioning heat exchangers, in particular to a universal device for automatic pipe-piercing and guiding of large-scale multi-hole heat exchangers. Background technique [0002] Air conditioning is the air conditioner (Air Conditioner). Refers to the equipment that uses manual means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. The structure of the air conditioner includes: compressor, condenser, evaporator, four-way valve, one-way valve, capillary assembly, etc. At present, the production process of heat exchangers for air conditioners is cumbersome and the degree of automation is low. Among them, the assembly process of long U copper tubes (copper tubes) and fins relies heavily on manual completion. With the development of technology, equipment (such as rake tooth positioning device) that can assist in ...

Problems solved by technology

At present, the production process of heat exchangers for air conditioners is cumbersome and the degree of automation is low. Among them, the assembly process of long U copper tubes (copper tubes) and fins relies heavily on manual completion.

With the development of technology, equipment (such as rake tooth positioning device) that can assist in guiding pipe penetration has appeared on the market. After the long U tube and the fin holes are accurately positioned, the tube is threaded, but this type of equipment can basically only handle the tube threading operation of the fin with a small number of holes, and the fin with a large number of holes due to its long length , the overall volume is large, the length of the guide parts (rake teeth) required in the guidance process is also long, the processing of the guide plate is difficult, and at the same time, it is easy to deform during the guidance process, resulting in a decrease in the guidance accuracy of the copper tube. However, the guidance process needs to ensure accuracy, stability, etc., which cannot be handled by existing equipment, and the guidance process through the pipe still has a strong dependence on labor
