Embodiment Construction
[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0043] Such as figure 1 As shown, it is a schematic diagram of the structure of the valve body 10 with thin straight capillary tubes before bending. One side of the valve body is welded and fixed with a D tube 11, and the other side opposite to the D tube is welded and fixed with S tubes 12 parallel to each other. , E pipe 13 and C pipe 14, S pipe is located between E pipe and C pipe.
[0044] Such as figure 2 As shown, it is a schematic diagram of the structure of the four capillary tubes after one bending. After one bending, the four capillary tubes are bent into an inverted L shape, and the end of the E tube 13 away from the valve body and the end of the C tube 14 away from the valve body are both outward. Open at an angle.
[0045] Such as image 3 As shown, it is a schematic diagram of the structure of the E tube 13 and the C tube 14 af...

The invention provides automatic pipe bending equipment for capillary tubes of a four-way reversing valve and relates to the technical field of mechanical production equipment. The automatic pipe bending equipment comprises a base; the base is provided with a fed material positioning module, a first-time bending tool, a second-time bending tool and a shaping tool; the fed material positioning module is fixedly arranged on the base and is used for positioning a supporting valve body during a bending process; the first-time bending tool is matched with the fed material positioning module in order to perform first-time bending formation of a tube D, a tube S, a tube E and a tube C; the shaping tool is arranged close to the fed material positioning module and is matched with the first-time bending tool during a first-time bending formation process so as to expand the tube S, the tube E and the tube C; the second-time bending tool is matched with the fed material positioning module in order to perform second-time bending formation of the tube E and the tube C. The automatic pipe bending equipment for the capillary tubes of the four-way reversing valve, provided by the invention, is simple in overall structure, capable of automatically implementing bending processing of four capillary tubes by two steps by using the first-time bending tool and the second-time bending tool, high in work efficiency, good in bending effect and low in production cost.
Description
technical field [0001] The invention relates to the technical field of valve accessory production equipment, in particular to a pipe bending device for automatically bending capillary pipes on a four-way reversing valve. Background technique [0002] The four-way reversing valve is an essential part of the air conditioner, which is used to switch the flow direction of the refrigerant to realize the switching between the cooling mode and the heating mode of the air conditioner. The four-way reversing valve is generally composed of three parts: pilot valve, main valve and electromagnetic coil. Among them, the pilot valve includes conduit, pilot valve body, capillary, attractor parts, core iron parts and pilot valve seat and other parts. Contains E tube, S tube, C tube and D tube. When the pilot valve and the main valve are assembled, the four capillary tubes need to be assembled at a certain angle and distance to ensure the normal operation of the four-way valve. [0003] Th...
