A processing technology for d-connection pipe of four-way reversing valve

Abstract

The present invention discloses a four-way reversing valve D connection tube processing process, which comprises that: 1, a cooper tube to be processed is subjected to material feeding through an automatic material feeding machine; 2, an automatic tube bending machine performs automatic tube bending on the cooper tube from the step 1, wherein the automatic tube bending process is performed by using a special D connection tube automatic folding-bending machine to process; 3, tube end forming is performed, wherein the tube end forming completes the final product forming on a special D connection tube end machine; and 4, the formed D connection tube is subjected to cleaning, inspection and warehousing. Compared with the processing process in the prior art, the processing process of the present invention has the following characteristics that: the whole four-way reversing valve D connection tube processing process from material feeding to finished product obtaining adopts automation production equipment so as to increase production efficiency, reduce labor cost, ensure product quality, and achieve good effects in the field of energy saving, emission reducing and clean production.

Description

technical field [0001] The invention relates to a processing technology for a D connection pipe of a four-way reversing valve, belonging to the technical field of metallurgical composite pipe bending and pipe end forming. Background technique [0002] The reversing valve D takes over as the reversing device of some equipment such as air conditioners, and its market demand has greatly increased. The existing manufacturing process of the reversing valve D pipe is as follows: the first step: automatic blanking machine blanking; the second step: manual loading and unloading Put a single copper tube into the chamfering machine, and chamfer the flaring end in the next step Deburring treatment to ensure the next step of the process: the third step: manual loading and unloading to expand a single copper tube on the hydraulic forming machine; the fourth step: manual loading and unloading to bend the tube on the manual pipe bender; fifth step: due to Copper shavings are produced duri...

Problems solved by technology

[0003] The above processes are all manually operated from the cutting of the material to the finished product. The whole process requires 5 people to form a manual assembly line to carry out the operation. It is calculated as a group of 5 people. A shift is calculated as 8 hours, and a group of manual assembly lines The upper limit of single-shift output is 12,000; the production efficiency of products is extremely low, and the labor intensity of workers is also high, and the pass rate of products is low and the consistency is poor; at the same time, when the demand for products increases, it can only be achieved by increasing the number of workers. To increase production, due to the high requirements for the operational skills of the workers, it is often impossible to organize the workers to arrive in place in time, which will increase the management and operating costs of the enterprise, and cause major losses in reputation and economy.
