Description

Technical Field

[0001] This utility model relates to the field of pipe bending equipment technology, specifically a capillary pipe bending tooling device used in refrigerator compressors. Background Technology

[0002] Capillary tubes are classified in different ways. Based on precision and application, capillary tubes can be divided into high-grade, mid-grade, and ordinary grades. The main function of a refrigerator capillary tube is to connect the condenser and evaporator, controlling the cooling effect by reducing the pressure of the high-pressure liquefied refrigerant delivered by the compressor. In a refrigeration system, the length and diameter of the capillary tube directly affect the refrigerant flow rate, thus achieving precise control of the cooling effect. During processing, capillary tubes require bending, and after processing, they need to be removed. However, after being bent at multiple angles, they often become stuck on the outside of the processing column, making removal difficult. This often requires bending the capillary tube outwards, which can easily lead to deformation and affect its quality. Utility Model Content

The front end of the telescopic spring contacts the rear side wall of the limiting block. A cylinder mounting plate is installed on the top of the pipe bending machine body and on the right side of the pipe bending machine body. A cylinder is installed above the cylinder mounting plate. The telescopic end of the cylinder on the left side passes through the cylinder mounting plate and extends to the right side of the pipe bending machine body.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a capillary tube bending fixture for use in refrigerator compressors, including a base plate 11 and a telescopic end 15. A bending machine body 1 for bending capillary tubes 17 is mounted on the top of the base plate 11. The telescopic end 15, after bending, is locked onto the outside of the bending machine body 1. A cavity is formed in the front side wall of the bending machine body 1, and a second limiting post 3 is provided inside the cavity. A first limiting post 2 for limiting the movement distance of the second limiting post 3 is installed inside the cavity. A telescopic spring 12 for pushing the second limiting post 3 inward is sleeved on the outside of the second limiting post 3. A limiting block 4 is installed near the front end of the cavity of the bending machine body 1, and the limiting block 4 is sleeved on the second limiting post 3. On the outside of column 3, the front end of the telescopic spring 12 contacts the rear side wall of the limiting block 4. A cylinder mounting plate 9 is installed on the top of the pipe bending machine body 1 and on the right side of the pipe bending machine body 1. A cylinder 10 is installed above the cylinder mounting plate 9. The telescopic end 15 on the left side of the cylinder 10 passes through the cylinder mounting plate 9 and extends to the right side of the pipe bending machine body 1. A push rod 8 is installed on the left end of the telescopic end 15. The left end of the push rod 8 extends into the inside of the pipe bending machine body 1 and contacts the end of the second limiting column 3. A sliding groove is provided on the top of the pipe bending machine body 1 for the bending limiting column 14 to slide. The bending limiting column 14 is slidably engaged on the top of the pipe bending machine body 1. The bottom of the bending limiting column 14 is connected to the left end of the push rod 8.

[0022] Furthermore, two top limiting columns 13 are installed on the top of the tube bending machine body 1 and on both sides of the bending limiting column 14 to limit and support the capillary tube 17. The two top limiting columns 13 are installed to support the right side of the capillary tube 17, and then the bending limiting column 14 pushes the capillary tube 17 to bend to the right.

[0023] Furthermore, a pad 5 is installed on the top of the pipe bending machine body 1 and on the left side, a clamping block 6 is installed above the pad 5, and a pressure cap 7 is installed above the clamping block 6.

[0024] Furthermore, the base plate 11 has a number of mounting holes 16 on its top, and the cylinder mounting plate 9 has screw holes on its top. The cylinder mounting plate 9 and the base plate 11 are fixed together by bolts passing through the screw holes and mounting holes 16. The base plate 11 is fixed in position by the cooperation of bolts and mounting holes 16.

[0025] Furthermore, the left end of the push rod 8 and the end of the second limiting post 3 that extend into the body 1 of the pipe bending machine are both provided with rounded corners. When the push rod 8 moves to the left and contacts the second limiting post 3, it first contacts through the rounded corners, thereby improving the smoothness of the push rod 8 pushing the second limiting post 3 to move and improving the stability of operation.

[0026] Furthermore, the right side wall of the bending limiting post 14 is arc-shaped. When the bending limiting post 14 moves to the leftmost position, the straight tube of the capillary tube 17 can be directly inserted between the bending limiting post 14 and the two top limiting posts 13. In the straight tube state, the capillary tube 17 extends through the gap between the top limiting post 13 and the bending limiting post 14. Then, the cylinder 10 drives the push rod 8 to move to the right through the telescopic end 15. The push rod 8 drives the bending limiting post 14 to move to the right, thereby realizing the partial bending of the capillary tube 17.

[0027] In operation, the control cylinder 10 moves the telescopic end 15 to the right, which in turn moves the push rod 8 to the right. The push rod 8 then moves the bending limit post 14 to the right to bend the capillary tube 17 located to the left of the top limit post 13. Afterward, the control cylinder 10 extends the telescopic end 15 outward, which in turn moves the push rod 8 to the left. The push rod 8 then pushes the second limit post 3 outward to the outside of the tube bending machine body 1, where it is stopped by the second limit post 3. After this, the capillary tube 17 can be bent. Once the bending is complete, the capillary tube 17... The control cylinder 10, positioned outside the second limiting post 3, drives the telescopic end 15 to retract. The telescopic end 15 then moves the push rod 8 to the right. After the push rod 8 moves to the right, it releases the support on the inner side of the second limiting post 3. The second limiting post 3, supported by the telescopic spring 12, retracts into the interior of the tube bending machine body 1, thereby releasing the limiting effect of the second limiting post 3 on the capillary tube 17. Then, the capillary tube 17 can be quickly removed, improving processing efficiency. Furthermore, the capillary tube 17 will not be bent or deformed when it is removed, thus ensuring the quality of the capillary tube 17.
