Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a high-strength cold extrusion crimping pipe processing tool that facilitates material cutting. Background Technology

[0002] In the processing of high-strength cold-extruded crimped tubes, the tubes must first be stably clamped, then crimped using a cold extrusion process, and finally unloaded. Currently, traditional processing fixtures often use single-sided or double-sided clamping structures in the clamping stage, which makes it difficult to achieve precise alignment of the tubes and easily leads to clamping deviation. This results in uneven transmission of extrusion pressure during cold extrusion, affecting the strength and precision of the processed tubes. At the same time, the displacement and unloading structures of traditional fixtures are independent of each other, resulting in poor flexibility in displacement adjustment. Furthermore, manual assistance is required for unloading after processing, which not only increases labor costs but also reduces overall processing efficiency. Therefore, it is necessary to design a high-strength cold-extruded crimped tube processing fixture that facilitates unloading to solve the above problems. Utility Model Content

[0009] Preferably, both clamping blocks are arc-shaped, and the arc-shaped structures of the two clamping blocks are arranged opposite to each other to form a circular clamping space for clamping the pipe fitting.

[0010] Preferably, each of the six fixing rods is movably connected to the guide groove.

[0011] Preferably, the spaced sector blocks and the centering clamping blocks together form a complete annular structure, and the clamping surface of the centering clamping blocks is an arc-shaped surface that matches the outer wall of the pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, through the mutual cooperation between the drive motor, pinion, external gear ring, connecting plate, and centering clamping block in the rotating fixing device, the drive motor drives the pinion to rotate after starting. The pinion meshes with the external gear ring to make it rotate, and the external gear ring drives the connecting plate to rotate synchronously. The guide groove on the connecting plate guides the fixing rod, thereby driving the centering clamping block to move between the spaced sector blocks. The centering clamping block accurately centers and tightly clamps the pipe fitting, effectively avoiding clamping deviation, ensuring uniform transmission of extrusion pressure during cold extrusion, and ensuring the strength and precision of the processed pipe fitting.

[0016] 2. In this utility model, through the mutual cooperation between the electric push rod one, the displacement plate, the electric push rod two, the connecting plate, the electric push rod three, and the clamping block in the displacement device, the electric push rod one drives the displacement plate to adjust the lateral position along the slide groove, the electric push rod two drives the connecting plate to adjust the longitudinal position, and the electric push rod three pushes the clamping block to close or open. By clamping the pipe fitting with the clamping block, the position of the pipe fitting can be flexibly adjusted. After processing, the pipe fitting can also be transferred to the unloading table by the displacement device, and the unloading can be completed without manual assistance, thus improving processing efficiency.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A high-strength cold-extruded crimping tube processing tooling that facilitates material cutting, such as Figure 1-5 As shown, the workbench 1 is included. A fixing plate 3 is fixedly connected to the upper right end of the workbench 1. A power supply box 4 is fixedly connected to the rear right end of the workbench 1. A rotating fixing device 2 is fixedly connected to the lower end of the fixing plate 3. A sliding groove 6 is opened on the upper left side of the workbench 1. A displacement device 7 is fixedly connected to the left front end of the workbench 1. A feeding table 5 is fixedly connected to the upper front end of the workbench 1 at an incline.

[0028] The power supply box 4 is electrically connected to the drive motor 21, electric push rod 1 71, electric push rod 2 73 and electric push rod 3 75 respectively via wires.

[0029] Through the above scheme, the power supply box 4 provides centralized power to the drive motor 21, electric push rod 1 71, electric push rod 2 73 and electric push rod 3 75 through wires, realizing unified management and control of the power source of the entire tooling, ensuring the coordination and reliability of the actions of each actuator. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power components and the power supply are common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail.

[0030] Please see Figure 3 and Figure 5The rotating fixing device 2 includes a drive motor 21. The output end of the drive motor 21 passes through the fixing plate 3 and is fixedly connected to a pinion 22. An external gear ring 27 is meshed with the left side of the outer surface of the pinion 22. An upper fixing ring plate 23 is sleeved on the outer side of the external gear ring 27. A connecting disc 28 is fixedly connected to the inner ring wall of the external gear ring 27. A through guide groove 29 is opened at the upper end of the connecting disc 28. An arc-shaped groove 26 is opened on the right side of the outer surface of the external gear ring 27. A plurality of support rods 24 are fixedly connected to the lower end of the upper fixing ring plate 23. A base plate 25 is fixedly connected to the lower end of the support rods 24. A spacer sector block 212 is fixedly connected to the middle of the upper end of the base plate 25. Six spacer sector blocks 212 are provided. A centering clamping block 211 is movably connected between adjacent spaced sector blocks 212. There are six centering clamping blocks 211. A fixing rod 210 is fixedly connected to the top side of each centering clamping block 211. The base plate 25 is fixedly connected to the upper end of the workbench 1. The drive motor 21 is fixedly connected to the lower end of the fixing plate 3. The six fixing rods 210 are movably connected to the guide groove 29. The spaced sector blocks 212 and the centering clamping blocks 211 together form a complete ring structure. The clamping surface of the centering clamping block 211 is an arc-shaped surface that matches the outer wall of the pipe. Multiple support rods 24 are evenly distributed along the circumference of the upper fixing ring plate 23 and are vertically fixedly connected to the base plate 25.

[0031] Through the above scheme: when it is necessary to clamp and compress the pipe fitting to meet the requirements of high-strength cold extrusion crimping processing, after the drive motor 21 starts, its output end passes through the fixed plate 3 and drives the pinion 22 to rotate. The pinion 22 meshes with the left side of the external gear ring 27, so that the external gear ring 27 rotates stably within the upper fixed ring plate 23. The upper fixed ring plate 23 is stably supported by multiple support rods 24 that are evenly distributed around the circumference and vertically fixed to the base plate 25. The base plate 25 is fixed on the worktable 1 to further ensure the stability of the overall structure. When the external gear ring 27 rotates, it drives the connecting plate 28 fixed to its inner ring wall to rotate synchronously. The guide groove 29 on the connecting plate 28 guides the fixed rods 210 that are movably connected therein. The function forces the fixed rod 210 to move the centering clamping block 211 fixed thereto between the six spaced sector blocks 212. Since the spaced sector blocks 212 and the centering clamping block 211 together form a complete ring, and the clamping surface of the centering clamping block 211 is an arc-shaped surface that matches the outer wall of the pipe, the pipe can be accurately centered and tightly clamped from multiple directions. At the same time, the arc groove 26 on the right side of the outer surface of the outer toothed ring 27 can help reduce friction and improve rotational stability when it rotates, effectively preventing the pipe from shifting or loosening during the clamping process. This ensures that the clamping extrusion pressure is evenly transmitted to the pipe during the subsequent cold extrusion crimping process, ensuring the strength and precision of the pipe after processing and meeting the processing requirements of high-strength cold extrusion crimped pipe.

[0032] Please see Figure 4The displacement device 7 includes an electric push rod 1 71 and an electric push rod 2 73. The output end of the electric push rod 1 71 passes through the workbench 1 and is fixedly connected to a displacement plate 72. The output end of the electric push rod 2 73 passes through the displacement plate 72 and is fixedly connected to a connecting plate 74. The front and rear ends of the connecting plate 74 are both fixedly connected to an electric push rod 3 75. The output end of the electric push rod 3 75 passes through the connecting plate 74 and is fixedly connected to a clamping block 76. The inner wall of the clamping block 76 is fixedly connected to a rubber pad 77. The electric push rod 1 71 is fixedly connected to the front left of the workbench 1. The electric push rod 2 73 is fixedly connected to the upper right of the displacement plate 72. The bottom of the vertical section of the displacement plate 72 is slidably connected in the slide groove 6. The connecting plate 74 has a concave structure and the opening direction is downward. The two clamping blocks 76 have an arc-shaped structure. The arc-shaped structures of the two clamping blocks 76 are arranged opposite each other to form a circular clamping space for clamping pipe fittings.

[0033] Through the above scheme: In the displacement device 7, electric push rod 1 71 drives the displacement plate 72 to move along the slide 6 to adjust the lateral position, electric push rod 2 73 drives the connecting plate 74 to move up and down to adjust the longitudinal position, electric push rod 3 75 pushes the clamping block 76 to close or open, rubber pad 77 increases friction and protects the pipe, concave connecting plate 74 and relatively arc-shaped clamping block 76 form a circular clamping space, which can stably clamp the pipe to complete the clamping and extrusion operation, and can also move the processed pipe to the designated position through displacement adjustment to achieve clamping and unloading, thus improving the efficiency of processing and unloading.

[0034] It should be noted that this utility model is a high-strength cold-extruded crimping tube processing fixture that facilitates material unloading. During operation, the power supply box 4 supplies power to the drive motor 21, electric push rod 71, electric push rod 73, and electric push rod 75 via wires. During processing, the tube to be cold-extruded and crimped is placed in the rotating fixing device 2. The drive motor 21 starts, driving the pinion 22 to rotate. The pinion 22 meshes with the external gear ring 27, causing it to rotate within the upper fixing ring plate 23. The external gear ring 27 drives the fixing rod 210 to move through the guide groove 29 of the connecting plate 28, causing the six centering clamping blocks 211 to move between the spaced sector blocks 212, utilizing the arc-shaped clamping... The pipe fitting is centered and clamped together with the fixed-spaced fan-shaped block 212 and the centering clamping block 211 to form a ring structure. The support rod 24 ensures that the upper fixed ring plate 23 and the bottom plate 25 are stably connected. Then the displacement device 7 operates. The electric push rod 1 71 drives the displacement plate 72 to move along the slide groove 6 to adjust its position. The electric push rod 2 73 drives the concave connecting plate 74 to move up and down to adjust its longitudinal position. The electric push rod 3 75 pushes the oppositely arranged arc-shaped clamping block 76 to close. After processing, the displacement device 7 adjusts the position through each electric push rod and moves the pipe fitting to the unloading table 5. The electric push rod 3 75 drives the clamping block 76 to open. The pipe fitting is unloaded through the inclined unloading table 5, realizing the efficient operation of the entire processing and unloading process.
