Description

Technical Field

[0001] This utility model relates to the technical field of copper tube bending equipment, specifically to an automatic bending device for precision copper tubes in refrigeration equipment. Background Technology

[0002] A search revealed a "steel pipe bending processing device" in patent document CN202023089016.4. This device includes a cylinder, a boss, a cylinder rotation mechanism, a connecting frame, a pressure block, a pressure block moving mechanism, a steel pipe positioning mechanism, and a heating mechanism. The pressure block is moved by the pressure block moving mechanism, pressing the end of the steel pipe between the pressure block and the cylinder. By rotating the cylinder and the pressure block, the end of the steel pipe is bent. This application simplifies the equipment structure and saves costs.

[0003] Another patent document, CN202221556252.9, discloses a "steel pipe bending device," which includes a device body and a steel pipe positioning mechanism, with a positioning seat installed inside the steel pipe positioning mechanism. Although this patent solves the problem of frequent screw rotation and increased workload for workers in the aforementioned patent, it still requires manual operation of the control handle, despite enabling automatic return of the positioning block. Therefore, the degree of automation is low. To address this, we propose an automatic precision copper pipe bending device for refrigeration equipment to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an automatic bending device for precision copper tubes in refrigeration equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic bending device for precision copper tubes in refrigeration equipment, comprising a bending mechanism, a copper tube body, a fitting fixing mechanism, and a driving mechanism. The copper tube body is inserted and installed on the bending mechanism and the fitting fixing mechanism. The fitting fixing mechanism is used to fix the copper tube body, and the driving mechanism is used to drive the clamping end in the fitting fixing mechanism.

[0006] The pipe fitting fixing mechanism includes a fixing frame, a lower support seat is installed at the bottom of the inner wall of the fixing frame, guide rods are symmetrically installed between the top and bottom of the inner wall of the fixing frame, an upper pressure seat is slidably connected to the two guide rods along the axial direction, a thrust spring is sleeved on the surface of the guide rod, and the top and bottom ends of the thrust spring are fixedly connected to the upper pressure seat and the bottom of the inner wall of the fixing frame, respectively.

[0007] The driving mechanism includes a connecting block, which is fixedly installed on the top of the fixed frame. A movable block is slidably connected in the groove at the bottom of the connecting block in the vertical direction. The bottom of the movable block extends through the fixed frame and is welded with a pressure seat.

[0008] Furthermore, a screw is threaded into the screw hole at the top of the movable block, and a transmission cavity is opened inside the connecting block. The top end of the screw passes through the transmission cavity and is fixedly connected to a driven bevel gear. A stepper motor is fixedly installed on the outside of the connecting block, and the output shaft of the stepper motor passes through the transmission cavity and is fixedly connected to a driving bevel gear that matches the driven bevel gear.

[0009] Furthermore, a limiting rotating plate is fixedly connected to the surface of the screw and below the transmission cavity. The limiting rotating plate is movably connected to the connecting block. The top of the fixed frame is provided with a guide opening that matches the movable block. The limiting rotating plate plays a limiting role for the screw, which can prevent it from moving axially and causing unstable gear meshing.

[0010] Furthermore, the bending mechanism includes a bending motor, a bracket, and a cylinder. The cylinder is fixedly installed on the inner side of the bracket, the output shaft of the bending motor is fixedly connected to the bottom of the bracket, and a side clamping block is also slidably connected to the inner side of the bracket in a transverse direction.

[0011] Furthermore, a hydraulic cylinder is fixedly installed on the right side of the inner wall of the bracket, and the telescopic end of the hydraulic cylinder is fixedly connected to the side clamping block.

[0012] Furthermore, the centerline of the cylinder is collinear with the centerline of the output shaft of the bending motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention involves inserting the copper tube to be bent through a fixed frame, placing it on a lower support, then passing it through the inner side of the bracket and fitting it against a cylinder. During fixation, a stepper motor is activated, causing its output shaft to drive a driving bevel gear to rotate. The driven bevel gear meshing with this gear drives a screw to rotate under the connection of a limiting plate. A movable block threaded onto the screw, limited by a guide port, drives a pressing seat to move vertically downwards, pressing down on an upper pressing seat. The upper pressing seat, connected to two guide rods, moves vertically downwards, clamping the copper tube. A bending mechanism then bends the tube. After completion, the stepper motor output shaft rotates in the opposite direction, causing the movable block to move the pressing seat upwards. A thrust spring then pushes the upper pressing seat back to its original position. This precision copper tube automatic bending device in refrigeration equipment has a reasonable structural design and is easy to use. It uses an automatic clamping method to fix the copper tube to be bent, eliminating the need for manual operation, thus effectively reducing the labor intensity of workers and improving work efficiency, exhibiting a high degree of automation.

The guide rods 33 play a limiting role for the upper pressure seat 34, which can ensure that it can move in the vertical direction.

[0024] Specifically, a thrust spring 35 is sleeved on the surface of the guide rod 33. The top and bottom ends of the thrust spring 35 are fixedly connected to the upper pressure seat 34 and the bottom of the inner wall of the fixed frame 31, respectively. The thrust spring 35 can drive the upper pressure seat 34 to return to its original position.

[0025] Specifically, the drive mechanism 4 includes a connecting block 41, which is fixedly installed on the top of the fixed frame 31. A movable block 42 is slidably connected in the groove at the bottom of the connecting block 41 in the vertical direction. The bottom of the movable block 42 extends through the fixed frame 31 and is welded with a pressing seat 43. The pressing seat 43 can be used to push the upper pressing seat 34 downward.

[0026] Specifically, a screw 44 is threaded into the screw hole at the top of the movable block 42, a transmission cavity 45 is opened inside the connecting block 41, the top end of the screw 44 passes through the transmission cavity 45 and is fixedly connected to the driven bevel gear 46, a stepper motor 47 is fixedly installed on the outside of the connecting block 41, and the output shaft of the stepper motor 47 passes through the transmission cavity 45 and is fixedly connected to the driving bevel gear 48 that is adapted to the driven bevel gear 46.

[0027] Specifically, a limiting rotating plate 49 is fixedly connected to the surface of the screw 44 and below the transmission cavity 45. The limiting rotating plate 49 is movably connected to the connecting block 41. The top of the fixed frame 31 is provided with a guide port 36 that matches the movable block 42.

The driven bevel gear 46 meshing with it can drive the screw 44 to rotate under the connection of the limiting rotating plate 49. The movable block 42 threaded on the screw 44, under the limit of the guide port 36, drives the pressing seat 43 to move vertically downward, thereby pressing down on the upper pressing seat 34. The upper pressing seat 34 can move vertically downward under the connection of the two guide rods 33, thereby pressing the copper tube body 2. Then, the bending mechanism 1 is used to bend it. After completion, the output shaft of the stepper motor 47 rotates in the opposite direction, so that the movable block 42 drives the pressing seat 43 to move upward. The thrust spring 35 can then push the upper pressing seat 34 to return to its original position automatically.
