Description

Technical Field

[0001] This application relates to the technical field of refrigeration machine condenser tube processing, and in particular to a manual bending device for bending the end of refrigeration machine condenser tubes. Background Technology

[0002] A refrigeration machine is a machine that transfers heat from a cooled object at a lower temperature to the surrounding environment to obtain cooling.

[0003] The condenser tubes used in refrigeration machines need to be bent at the ends during production to connect with other tubes. In the current technology, this is usually done manually. However, the existing manual bending mechanism can only bend one tube at a time, resulting in low production efficiency. Utility Model Content

[0004] The purpose of this application is to provide a manual bending device for bending the end of a refrigeration unit's condenser tube, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a manual bending device for bending the ends of condenser tubes in a refrigeration unit, employing the following technical solution:

[0006] A manual bending device for bending the end of a refrigeration unit condenser tube includes a worktable and a bending mechanism mounted on the worktable. The bending mechanism includes a stationary clamping block, a movable clamping block, a rotating arm, a bending roller, and a push-pull quick clamp. The stationary clamping block is fixed on the worktable, and the movable clamping block is slidably connected to the worktable and is correspondingly arranged with the stationary clamping block. The push-pull quick clamp is fixed on the worktable and is used to drive the stationary clamping block to move. The rotating arm is rotatably connected to the bottom of the stationary clamping block, and the bending roller is rotatably connected to the rotating arm. Both the stationary and movable clamping blocks include a cylinder and an extension block. The cylinder and the extension block are integrally formed, and the diameter of the cylinder is larger than the width of the extension block. Both the stationary and movable clamping blocks have interconnected arc-shaped positioning grooves on their surfaces. The bending roller has an annular bending groove on its surface corresponding to the position of the arc-shaped positioning groove.

[0007] The workbench is also equipped with a support mechanism for supporting the condenser tubes.

[0008] Preferably, the support mechanism includes a fixed block, an extrusion block, and a cylinder. The surfaces of the fixed block and the extrusion block are provided with arc-shaped guide grooves. When the fixed block and the extrusion block are combined, the arc-shaped guide grooves on both sides can form guide holes. The extrusion block is slidably connected to the worktable, and the cylinder is used to drive the extrusion block to slide.

[0009] By adopting the above technical solution and by setting up a support mechanism, it is possible to assist the staff in fixing the condenser tubes into the bending mechanism. When in use, the cylinder pushes the extrusion block against the side of the fixed block. The arc-shaped guide grooves on the surfaces of the fixed block and the extrusion block can form guide holes. At this time, the staff only needs to insert multiple condenser tubes into the guide holes in sequence, which is convenient for feeding.

[0010] Preferably, the end edge of the arc-shaped guide groove is chamfered to facilitate the insertion of the condenser tube.

[0011] Preferably, in order to provide support for the end of the condenser tube, a support block is also provided on the worktable. The support block is located next to the fixed block and on the side away from the bending mechanism. Multiple support grooves are opened inside the support block. The support grooves are arranged one-to-one with the guide holes. The side of the support groove near the cylinder is open.

[0012] Preferably, in order to facilitate operation by staff, a handle is fixed on the rotating arm based on ergonomics.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. The manual bending device for bending the ends of the condenser tubes of this refrigeration unit can bend multiple condenser tubes at once, which greatly improves production efficiency;

[0015] 2. With the support mechanism and support block, it can assist the staff in loading materials. The support mechanism has multiple vertically evenly arranged guide holes. The staff only needs to insert the condenser tube into the guide hole. The loading efficiency is high, the labor intensity of the staff is low, and it is easy to operate. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-2This application will be described in further detail.

[0020] This application discloses a manual bending device for bending the end of a refrigeration unit's condenser tube, as shown in the following embodiments. Figure 1-2 The system includes a worktable 1 and a bending mechanism 2 mounted on the worktable 1. The bending mechanism 2 includes a stationary clamping block 21, a movable clamping block 22, a rotating arm 23, a bending roller 24, and a push-pull quick clamp 25. The stationary clamping block 21 is fixed on the worktable 1, and the movable clamping block 22 is slidably connected to the worktable 1, with the movable clamping block 22 corresponding to the stationary clamping block 21. The push-pull quick clamp 25 is fixed on the worktable 1 and is used to drive the movement of the stationary clamping block 21. The rotating arm 23 is rotatably connected to the bottom of the stationary clamping block 21. A handle 231 is fixed on the rotating arm 23. The bending roller 24 is rotatably connected to the rotating arm 23. The stationary clamping block 21 and the moving clamping block 22 both include a cylinder 211 and an extension block 212. The cylinder 211 and the extension block 212 are integrally formed, and the diameter of the cylinder 211 is larger than the width of the extension block 212. The surfaces of the stationary clamping block 21 and the moving clamping block 22 are provided with interconnected arc-shaped positioning grooves 2111. The surface of the bending roller 24 is provided with an annular bending groove 241 corresponding to the position of the arc-shaped positioning groove 2111.

[0021] Reference Figure 1 The workbench 1 is also equipped with a support mechanism 3 for supporting the condenser tube. The support mechanism 3 includes a fixed block 31, a pressing block 32 and a cylinder 33. The surfaces of the fixed block 31 and the pressing block 32 are provided with arc-shaped guide grooves. When the fixed block 31 and the pressing block 32 are combined, the arc-shaped guide grooves on both sides can form guide holes 34. The pressing block 32 is slidably connected to the workbench 1. The cylinder 33 is used to drive the pressing block 32 to slide. The end edge of the arc-shaped guide groove is chamfered (not shown in the figure).

[0022] With the support mechanism 3 provided, the operator can fix the condenser tube into the bending mechanism 2. When in use, the cylinder 33 pushes the extrusion block 32 against the side of the fixing block 31. The arc-shaped guide grooves on the surfaces of the fixing block 31 and the extrusion block 32 can form a guide hole 34. At this time, the operator only needs to insert multiple condenser tubes into the guide hole 34 in sequence, which is convenient for feeding.

[0023] Reference Figure 1 In order to provide support for the end of the condenser tube, a support block 4 is also provided on the workbench 1. The support block 4 is located next to the fixed block 31 and on the side away from the bending mechanism 2. Multiple support grooves 41 are opened inside the support block 4. The support grooves 41 are arranged one-to-one with the guide holes 34. The side of the support groove 41 near the cylinder 33 is open. At the same time, the end of the condenser tube can be positioned by abutting against the inner wall of the support groove 41.

[0024] The implementation principle of the manual bending device for bending the end of a refrigeration unit condenser tube in this application embodiment is as follows:

[0025] With the support mechanism 3 in place, during loading, the operator inserts multiple condenser tubes into the guide hole 34 in sequence. The support mechanism 3 provides support for the condenser tubes, allowing them to be embedded in the arc-shaped positioning groove 2111 on the side of the stationary clamping block 21 in a horizontal position. Afterward, the operator uses the push-pull quick clamp 25 to push the moving clamping block 22 against the stationary clamping block 21, which can clamp and fix multiple condenser tubes at once. After the condenser tubes are fixed, the rotating arm 23 is rotated, and the end of the condenser tubes is bent by the bending roller 24, which can achieve bending of multiple condenser tubes at once, greatly improving production efficiency.

[0026] After bending, the push-pull quick clamp 25 retracts, and the cylinder 33 drives the extrusion block 32 away from the fixed block 31, allowing the workers to easily remove multiple bent condenser tubes, making unloading more convenient.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
