Description

Technical Field

[0001] This utility model relates to the field of copper pipe bending technology, specifically a copper pipe bending and cutting device. Background Technology

[0002] Copper bends are an important pipe component with wide applications in many fields. With the development of various industries, the requirements for the dimensional accuracy, shape accuracy, and surface quality of copper bends are becoming increasingly stringent. For example, in the air conditioning and refrigeration industry, in order to improve refrigeration efficiency and system compactness, copper bends need to have smaller bending radii, more precise pipe diameters, and smoother inner surfaces. At the same time, with the trend of product miniaturization and high performance, the processing difficulty of copper bends is also constantly increasing, requiring more advanced processing technologies and equipment to meet these requirements. Currently, when processing the inner wall of copper bends, copper bend cutting equipment is needed to cut and process the inner wall of the copper bends.

[0003] Current cutting equipment can only cut one end of the copper bend when processing it. After cutting one end, the operator must manually adjust the position of the copper bend before cutting the other end, which increases the number of steps and time, greatly reducing cutting efficiency. Moreover, a large amount of debris is generated on the inner wall of the copper bend during the cutting process. Current cutting equipment is not convenient for cleaning up the debris, and a large amount of debris will be scattered on the processing table. The debris accumulates on the processing table, which in turn affects the accuracy and quality of subsequent cutting operations. Utility Model Content

[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 Figures 1-4 As shown, a copper bending pipe cutting device includes a base plate 1, a cutting table 2 fixed to the rear side of the top of the base plate 1, a lower positioning plate 3 bolted to the middle of the top of the cutting table 2, a fixing plate 4 fixed to the back of the cutting table 2, a hydraulic cylinder 5 installed above the front surface of the fixing plate 4, an upper positioning plate 6 fixed to the bottom end of the output shaft of the hydraulic cylinder 5, and bending pipe positioning grooves 7 are formed on the opposing surfaces of the upper positioning plate 6 and the lower positioning plate 3. The inner wall structure of the bending pipe positioning grooves 7 is adapted to the outer shape structure of the copper bending pipe. A fixing frame 8 is fixed to the top of the front of the fixing plate 4, and a movable joint is movably connected inside the fixing frame 8. The movable structure 9 has connecting plates 10 fixed on both the left and right sides of its bottom. A pusher plate 11 is fixed on the bottom of the connecting plate 10. Waste discharge grooves 12 are opened on both the left and right sides of the top of the cutting table 2. A support platform 13 is fixed on the left and right sides of the front side of the cutting table 2. A first motor 14 is installed on the front side of the support platform 13. A lead screw 15 is fixed at the rear end of the output shaft of the first motor 14. The lead screw 15 is rotatably connected to the support platform 13. A movable seat 16 is threaded on the surface of the lead screw 15. A drive device 17 is installed on the top of the movable seat 16. A cutting drill bit 18 is fixed on the surface of the output shaft of the drive device 17.

[0022] The support platform 13 is inclined, and the cutting drill bit 18 points to the center of the curved tube positioning groove 7 on the surface of the lower positioning plate 3. Guide rails 21 are fixed on both sides of the top of the support platform 13, and guide blocks 22 are fixed on both sides of the bottom of the moving seat 16. The guide blocks 22 are slidably connected to the guide rails 21. After the first motor 14 is turned on, the output shaft of the first motor 14 will drive the lead screw 15 to rotate, thereby causing the moving seat 16 to move on the surface of the lead screw 15. The setting of the guide rails 21 and the guide blocks 22 increases the stability of the cutting drill bit 18 when cutting. The cutting drill bits 18 on both sides move synchronously to approach the two ends of the copper curved tube inside the curved tube positioning groove 7. The drive device 17 is turned on, thereby driving the cutting drill bit 18 to rotate, and then cutting the inner wall of the copper curved tube.

[0023] The moving structure 9 includes a dual-head motor 91, a threaded rod 92, and a moving block 93. The dual-head motor 91 is fixed to the middle of the top of the inner wall of the fixed frame 8. The threaded rod 92 is rotatably connected to the left and right sides of the inner wall of the fixed frame 8, and the thread directions of the threaded rods 92 on the left and right sides are opposite. The moving block 93 is threaded to one side of the surface of the threaded rod 92. One end of the threaded rod 92 is fixedly connected to the output shafts on the left and right sides of the dual-head motor 91. The bottom of the moving block 93 is fixedly connected to the top of the connecting plate 10. The bottom of the pusher plate 11 is in contact with the top surface of the cutting table 2 and slides in contact with the surface of the cutting table 2. When the dual-head motor 91 is turned on, the output shaft of the dual-head motor 91 will drive the threaded rods 92 on the left and right sides to rotate synchronously. Since the thread directions of the threaded rods 92 on the left and right sides are different, the moving blocks 93 on the left and right sides move towards each other. The pusher plate 11 moves towards each other through the connecting plate 10. The pusher plate 11 pushes the cutting debris scattered on the surface of the cutting table 2 into the waste discharge trough 12 to clean up the waste.

[0024] Limiting grooves 19 are provided on both the left and right sides of the top of the fixed frame 8. A limiting block 20 is fixed on the top of the moving block 93. The limiting block 20 is located inside the limiting groove 19 and is slidably connected to the inner wall of the limiting groove 19. When the threaded rod 92 rotates, the limiting block 20 is inside the limiting groove 19 and limits the moving block 93 below, so that the moving block 93 can only move horizontally left and right to adjust the position of the push plate 11 below.

[0025] Working principle: The operator first places the copper bent tube to be processed into the bent tube positioning groove (7) on the surface of the lower positioning plate (3) on the cutting table (2). Then, the hydraulic cylinder (5) is started. The output shaft of the hydraulic cylinder (5) pushes the upper positioning plate (6) downward, so that the upper positioning plate (6) and the lower positioning plate (3) move towards each other until the bent tube positioning groove (7) on both surfaces tightly clamps the copper bent tube, thus fixing the workpiece. Then, the first motors (14) on both sides start at the same time. The output shaft of the first motor (14) drives the lead screw (15) to rotate. Since the lead screw (15) is threadedly connected to the moving seat (16), and the guide block (22) at the bottom of the moving seat (16) slides against the guide rail (21) at the top of the support table (13), the workpiece is fixed. With the movement coordinated, the moving seat (16) moves steadily backward along the inclined support platform (13) under the drive of the lead screw (15). The drive device (17) installed on the top of the moving seat (16) starts at the same time. The output shaft of the drive device (17) drives the cutting drill bit (18) to rotate at high speed. The cutting drill bits (18) on both sides move synchronously and accurately along the direction pointing to the center of the bend positioning groove (7) under the drive of the moving seat (16), and finally extend into the inner end ports of the copper bend. The high-speed rotating cutting drill bit (18) contacts the inner wall of the copper bend and completes the synchronous cutting operation of the inner wall of the two ends of the copper bend. The metal chips generated during the cutting process will be scattered on the top surface of the cutting table (2). After the cutting is completed, the first motor (1) 4) Reverse the direction, causing the lead screw (15) to rotate in the opposite direction, causing the moving seat (16) and the cutting drill bit (18) to move forward and reset and detach from the workpiece. Then the hydraulic cylinder (5) retracts, causing the upper positioning plate (6) to rise and release the copper bend. The operator can then remove the finished workpiece. To clean up the scattered debris, start the double-head motor 91. The output shafts on the left and right sides of the double-head motor (91) drive the threaded rods (92) on the left and right sides to rotate synchronously. Since the thread directions on the surfaces of the threaded rods (92) on the left and right sides are opposite, and the moving block (93) is threadedly connected to the threaded rod (92), and the limiting block (20) at the top of the moving block (93) is constrained to slide in the limiting groove (19) at the top of the fixed frame (8), the moving blocks on the left and right sides can rotate synchronously. (93) Driven by the rotating threaded rod (92), the moving block (93) moves horizontally towards each other. The moving block (93) drives the connecting plate (10) and the pusher plate (11) fixed at its bottom to move synchronously towards each other. The bottom of the pusher plate (11) slides close to the top surface of the cutting table (2), pushing the cutting debris scattered on both sides of the top of the cutting table (2) to the waste discharge groove (12) opened in the middle of the cutting table (2). The debris falls into the lower part through the waste discharge groove (12), realizing the automatic cleaning of the worktable. After the cleaning is completed, the double-head motor (91) reverses and drives the left and right threaded rods (92) to rotate in the opposite direction, so that the left and right moving blocks (93), the connecting plate (10) and the pusher plate (11) move back to their original positions, preparing for the next cutting and cleaning operation.
