Description

Technical Field

[0001] This utility model relates to the field of four-way valve upper pipe shaping technology, and in particular to a four-way valve upper pipe shaping mechanism. Background Technology

[0002] In refrigeration systems, air conditioning equipment, and industrial fluid control, the four-way valve is a crucial fluid control component. Its performance stability and reliability directly impact the overall system's operating efficiency and safety. By switching its internal valve core, the four-way valve controls the flow direction of fluid between different pipelines and is widely used in heat pump systems, multi-split air conditioning systems, and other similar applications.

[0003] In the manufacturing process of four-way valves, welding assembly is an indispensable and crucial step, ensuring a tight connection and structural stability between the valve's components. However, due to factors such as high temperature, thermal stress concentration, and material expansion and contraction during welding, the upper pipe section of the four-way valve often undergoes varying degrees of deformation. This deformation not only affects the overall appearance quality of the four-way valve, but more importantly, it can cause the upper pipe orifice to deviate from its designed position, thus affecting the precise connection with subsequent external pipelines or fittings.

[0004] Specifically, when the upper pipe is significantly deformed, directly proceeding to subsequent processes (such as inspection and assembly) can easily lead to problems such as connection difficulties, poor sealing, or even pipe damage due to inaccurate hole positioning. This results in a large number of scrapped or reworked parts, significantly increasing production costs and time. Therefore, effectively shaping the upper pipe of the four-way valve after welding and assembly to restore it to the design requirements has become a key step in improving the production quality and reducing production costs of four-way valves.

Detailed Implementation

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a four-way valve upper pipe shaping mechanism, including:

[0026] The base plate 1 has a four-way valve workpiece positioning plate 2 installed on it. The four-way valve workpiece positioning plate 2 has a groove for the four-way valve 9 to be placed. The bottom of the base plate 1 has two shaping cylinder fixing plates 5, and two fixing ears are fixed on the shaping cylinder fixing plates 5 so that they can be installed on the bracket by bolts.

[0027] The left shaping mechanism 6 and the right shaping mechanism 7 are installed on the base plate 1. The left shaping cylinder 4 and the right shaping cylinder 8 are respectively fixed on the two shaping cylinder fixing plates 5. The left shaping cylinder 4 is used to drive the left shaping mechanism 6 to move, and the right shaping cylinder 8 is used to drive the right shaping mechanism 7 to move.

[0028] The left shaping mechanism 6 includes a left shaping cylinder connecting plate 6-7 connected to the output end of the left shaping cylinder 4. A guided left sliding base fixing plate 6-5 is fixed on one side of the left shaping cylinder connecting plate 6-7. A left reinforcing rib 6-6 is fixed on the left sliding base fixing plate 6-5 and the left shaping cylinder connecting plate 6-7. An adjustable left shaping plate fixing plate 6-2, a left anti-workpiece tilting plate and a coil column inspection plate 6-3 are installed on the left sliding base fixing plate 6-5 (this part is integrated and Z-shaped, with anti-workpiece tilting function (the bottom is provided with an anti-tilting arc groove), and also has a coil column inspection function). A left shaping head 6-1 is fixed on the left shaping plate fixing plate 6-2.

[0029] The upper end of the left sliding base fixing plate 6-5 is fixed with a left distance adjustment plate 6-4. Two left adjustment screws 6-8 with threaded connection are provided through the left distance adjustment plate 6-4. The left adjustment screws 6-8 are rotatably installed with the left shaping plate fixing plate 6-2, the left anti-workpiece tilting plate and the coil column inspection plate 6-3.

[0030] The right shaping mechanism 7 includes a right shaping cylinder connecting plate 7-7 connected to the output end of the right shaping cylinder 8. A right sliding base fixing plate 7-5 is fixed on one side of the right shaping cylinder connecting plate 7-7 and is guided. A right reinforcing rib 7-6 is fixed between the right sliding base fixing plate 7-5 and the right shaping cylinder connecting plate 7-7. An adjustable right shaping plate fixing plate 7-2 and a right anti-workpiece tilting plate 7-3 are installed on the right sliding base fixing plate 7-5. A right shaping head 7-1 is fixed on the right shaping plate fixing plate 7-2.

[0031] The upper end of the right sliding base fixing plate 7-5 is fixed with a right distance adjustment plate 7-4. Two right adjustment screws 7-8 with threaded connection are provided through the right distance adjustment plate 7-4. The right adjustment screws 7-8 are rotatably installed with the right shaping plate fixing plate 7-2 and the right anti-workpiece tilting plate 7-3.

[0032] Based on the actual deformation of the upper pipe of the four-way valve, adjust the positions of the left shaping plate fixing plate 6-2, the left anti-workpiece tilting plate and coil post inspection plate 6-3, the right shaping plate fixing plate 7-2, and the right anti-workpiece tilting plate 7-3 by rotating the left adjusting screw 6-8 and the right adjusting screw 7-8, respectively. This ensures that the left shaping head 6-1 and the right shaping head 7-1 are accurately aligned with the deformed part of the upper pipe of the four-way valve. During the adjustment process, measuring tools can be used to ensure the positional accuracy of the shaping heads to meet the shaping requirements.

[0033] A linear slide rail 3 is fixed on the base plate 1. Guide blocks are fixed at the bottom of the left sliding base fixing plate 6-5 and the right sliding base fixing plate 7-5. The guide blocks slide on the linear slide rail 3 to ensure the stable movement of the left shaping mechanism 6 and the right shaping mechanism 7.

[0034] The left shaping mechanism 6 and the right shaping mechanism 7 work together to shape the upper pipe of the four-way valve on the left and then on the right, releasing the stress generated by welding on the workpiece, or the left and right shaping can be performed together and clamp the four-way valve.

[0035] Start the left shaping cylinder 4, driving the left shaping mechanism 6 to move along the linear slide rail 3 towards the upper pipe of the four-way valve. As the left shaping mechanism 6 moves, the left shaping head 6-1 gradually contacts and applies pressure to the deformed part of the upper pipe of the four-way valve, performing the left shaping operation. During the shaping process, carefully observe the deformation of the upper pipe of the four-way valve and adjust the shaping pressure as needed to avoid over-shaping and damage to the workpiece. Right shaping operation: After the left shaping is completed, start the right shaping cylinder 8, driving the right shaping mechanism 7 to move along the linear slide rail 3 towards the upper pipe of the four-way valve. The right shaping head 7-1 contacts and applies pressure to the deformed part on the other side of the upper pipe of the four-way valve, performing the right shaping operation. The right shaping operation can be performed in conjunction with the left shaping operation to release the stress generated by welding on the workpiece and improve the shaping effect.

[0036] Alternatively, the shaping mechanism can also achieve simultaneous left and right shaping while clamping the upper pipe of the four-way valve.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
