Embodiment

[0023] A four-way reversing valve D connection processing technology is characterized in that the specific steps are as follows:

[0024] The first step: automatic blanking machine blanking;

[0025] The second step: the automatic pipe bending machine automatically bends the copper pipe in the first step, and the automatic pipe bending process is processed by the D-connector automatic bending machine. The specific implementation steps are as follows:

[0026] (1) Discharging and feeding in the pipe bending process: through the conveying line feeding method, the finished materials are continuously discharged to the material box, and the material box has a certain storage capacity. The multi-stage material distribution mechanism rolls the material in the material box into the slideway according to the needs after multiple toggles, and the copper pipe enters the working slideway according to the predetermined path through the material distribution and blocking mechanism;

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...
