Description

Technical Field

[0001] The invention belongs to the technical field of pipe processing, and in particular relates to a pipe bending and flattening forming tool for fitness equipment. Background Art

[0002] The bending and flattening process in fitness equipment refers to the process of flattening, forming or adjusting the shape of the pipe through a specific process to adapt to specific design requirements or functions. This type of processing is common in the frames, supporting parts, connecting parts, etc. of the equipment. Currently, the common flattening processing methods are as follows: Hydraulic flattening: The pipe is clamped by a hydraulic press and pressure is applied to flatten the pipe in a specific area. Mechanical stamping: Use stamping equipment to apply impact force to the pipe to flatten it. Rolling or roller pressing: The pipe is gradually flattened by roller pressing. Flattening treatment after arc welding: During the welding process, certain parts of the pipe need to be flattened to ensure the stability of the welding point or to enhance local strength.

[0003] The bending and flattening processing of fitness equipment is mostly used for the processing of connectors, such as brackets, support columns, connecting columns, etc. Flattening is generally used to enhance the connection effect or make it more convenient to assemble with other components. At present, the bending and flattening processing of fitness equipment is usually performed independently by bending and flattening (usually also including punching). This processing technology not only requires the use of different processing equipment, but also wastes a lot of manpower and material resources. It is not only not conducive to improving production and processing efficiency, but also seriously affects the production and processing progress when processing in large quantities. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a fitness equipment bending tube flattening forming tool.

[0005] The technical solution adopted to solve the above technical problems is: a fitness equipment bending tube flattening forming tool, including a lower forming module and an upper forming module that cooperate with each other, the lower forming module includes a lower die base, and the upper forming module includes an upper die base;

[0006] Two limiting rods are fixedly connected to both sides of the top of the lower forming module, a connecting assembly is slidably connected between the two groups of limiting rods, and a first return spring is sleeved on the upper forming module;

[0007] The upper forming module is slidably mounted with stamping forming modules on both sides of the top, and a sliding extrusion module is slidably mounted on the upper forming module. During the downward pressing process, the two sets of stamping forming modules can be simultaneously pressed downward to complete the stamping forming of both ends of the pipe.

[0008] A support ejection module is also installed at the bottom center of the lower forming module, which is used to support the pipe before processing and eject the pipe after processing.

[0009] Furthermore, a lower forming groove is provided at the center of the top of the lower die base, and penetrating residual material punching holes and inner punching holes are respectively provided at both ends of the lower forming groove, and corresponding waste discharge grooves are provided on both sides of the bottom of the lower die base.

[0010] Through the above technical solution, the lower forming groove opened on the lower die base can cooperate with the upper forming groove opened in the bottom center of the upper die base to complete the bending forming of the pipe. After the lower forming module and the upper forming module are combined, the one-time bending forming of the pipe and the flattening of the connecting parts at both ends of the pipe can be realized. In addition, both ends of the lower forming groove are respectively provided with penetrating residual material punching holes and internal punching holes. After the pipe is bent and flattened, the punching processing of the flattened parts at both ends can be completed by two sets of stamping forming modules, so that the pipe can be processed and formed in one time to form the final formed bent pipe; the waste discharge grooves opened on both sides of the bottom of the lower die base are used to discharge excess waste generated after punching.

[0011] Furthermore, a U-shaped mounting hole is provided at the center of the bottom of the lower mold base.

[0012] The above technical solution can more conveniently support the installation and positioning of the ejection module.

[0013] Furthermore, two first limiting holes matching the corresponding limiting rods are provided at both ends of the upper mold base, an upper forming groove is provided at the bottom center of the upper mold base, and limiting sliding holes and limiting circular holes are respectively provided at both ends of the upper forming groove. A support block is fixedly connected to the top center of the upper mold base, and a guide column is fixedly connected to the top center of the support block. Guide rods are fixedly connected to both sides of the top of the upper mold base, and the top ends of the two guide rods are threadedly connected with limiting nuts.

[0014] Through the above technical solution, the upper forming groove opened at the bottom center of the upper die seat can cooperate with the lower forming groove during the mold closing process, thereby completing the one-time bending and forming of the pipe and the flattening of the connecting parts at both ends of the pipe; the limiting sliding holes and limiting circular holes opened at the ends of the upper forming groove can play a sliding limiting role in the installation of the stamping forming module, thereby ensuring the processing accuracy of the stamping forming module; the design of the two guide columns can make the entire upper forming module and the connecting assembly form a linkage structure, and in the process of the connecting assembly rising and resetting, it can also drive the upper forming module to reset for subsequent unloading.

[0015] Furthermore, the first return spring is sleeved on the outer wall of the guide column.

[0016] Through the above technical solution, during the processing, the piston rod of the hydraulic drive unit will drive the connecting component to move downward. During this process, the connecting component will squeeze the first return spring downward, and then drive the entire upper forming module to close the mold downward, so as to utilize the mutual cooperation of the lower forming module and the upper forming module to first complete the bending of the pipe and the flattening of the two ends. When the pipe processing is completed, after the hydraulic drive unit is reset, under the elastic reaction force of the first return spring, it will drive the connecting component and the sliding extrusion module to reset.

[0017] Furthermore, the connecting assembly includes a connecting frame that is sleeved between two groups of limit rods, and second limit holes for corresponding limit rods to pass through are opened at the corners of the connecting frame, and a guide hole for guide columns to pass through is opened at the center position of the connecting frame. Two third limit holes for corresponding guide rods to pass through are also opened on both sides of the connecting frame, and extrusion columns are fixedly connected to both sides of the bottom of the connecting frame, and connecting seats are fixedly connected to both sides of the top of the connecting frame.

[0018] Through the above technical solution, the connecting assembly is mainly used for the connection and transition between the hydraulic drive unit and the upper forming module. The two connecting seats are connected to the piston rod of the hydraulic drive unit. During actual use, the piston rod of the hydraulic drive unit drives the entire connecting assembly to rise and fall. In the process of bending and flattening the pipe, the connecting frame will first move downward to squeeze the first return spring, thereby driving the entire upper forming module to close the mold downward. When the upper forming module is completed, the connecting frame will continue to move downward, thereby causing the extrusion columns on both sides of the bottom of the connecting frame to squeeze the sliding extrusion module downward at the same time. Finally, the extrusion sliding extrusion module drives the two sets of stamping forming modules to complete the punching processing of the formed pipe. After the processing is completed, the connecting frame will also drive the upper forming module to reset during the rising and resetting process, thereby realizing automatic mold opening for subsequent unloading.

[0019] Furthermore, the stamping forming module includes a fixed block, the bottom of which is fixedly connected to a punching block and a punching column, respectively. The punching block and the punching column are respectively slidably limited in the corresponding limiting sliding hole and limiting circular hole. The outer wall of the punching column is also sleeved with a second return spring, and the top center of the punching column is fixedly connected to a fixed column, and the top of the fixed column is designed as an inclined surface.

[0020] Through the above technical solution, the stamping and forming module is mainly used for the punching processing of the two ends of the pipe after the bend is flattened and formed. During actual work, when the sliding extrusion module moves downward, the sliding extrusion module will simultaneously squeeze the fixed column downward, and then drive the punching block and the punching column to quickly perform shearing movement downward, so that the remaining material at the end of the flattened pipe can be sheared and punched to form the final formed bend. When the sliding extrusion module rises and resets, the elastic reaction force of the second reset spring will push the entire stamping and forming module to rise and reset.

[0021] Furthermore, the sliding extrusion module includes a fixed plate that slides on the outer walls of the two guide rods, and a fourth limiting hole is provided in the middle of the fixed plate for the guide column to pass through. Two fifth limiting holes are also provided on both sides of the fixed plate for the corresponding guide rods to pass through. Extrusion blocks are fixedly connected to both ends of the fixed plate, and the bottoms of the two extrusion blocks are provided with limiting grooves that match the corresponding fixed columns.

[0022] Through the above technical solution, the sliding extrusion module is mainly provided with downward extrusion force by the connecting assembly, and in the process of the sliding extrusion module moving downward, the extrusion blocks fixedly connected at both ends of the fixed plate will simultaneously squeeze the stamping forming module downward. At this time, the fixed column will slide in the limit groove and continue to descend in height, finally completing the punching processing operation.

[0023] Furthermore, the support ejection module includes an ejection seat slidably installed in the U-shaped mounting hole, support grooves are provided on both sides of the top of the ejection seat, a sixth limiting hole is provided in the center of the bottom of the ejection seat, a support column is slidably connected in the sixth limiting hole, the bottom of the support column is fixedly connected to the mounting plate, and the outer wall of the support column is sleeved with a third return spring.

[0024] Through the above technical solution, during the loading stage, due to the lifting effect of the third return spring, the heights of the two sides of the top of the ejector seat will exceed the horizontal height of the lower forming groove. At this time, the operator can place the pipe to be processed horizontally in the two supporting grooves, with the two ends roughly symmetrical. At this time, the ejector seat can provide stable support and positioning for the placed pipe. In the subsequent mold closing process, the ejector seat will also ensure that the pipe will not rotate or shift, thereby ensuring the processing accuracy and quality. After the processing is completed, during the rising and resetting process of the upper forming module, the third return spring loses its downward extrusion force. At this time, under the elastic reaction force of the third return spring, the ejector seat can move upward again, so that the formed elbow after processing can be ejected from the lower forming groove, making it more convenient to unload.

[0025] Furthermore, the ejector seat is designed to have a U-shaped structure, and the mounting plate is fixed to the bottom of the U-shaped mounting hole by a plurality of fixing screws.

[0026] Through the above technical solution, the U-shaped ejector seat can form a more stable support structure. At the same time, its overall structural design is also more convenient for rapid installation and fixation as well as daily inspection and maintenance.

[0027] The beneficial effects of the present invention are as follows: (1) The present invention can complete the bending, flattening, punching and other operations of the pipe at one time by designing the upper and lower forming modules and the stamping forming module. Manual labor only needs to complete the loading and unloading operations, which not only improves the production and processing efficiency, but also saves more manpower and material resources; (2) The present invention can complete the punching processing of the formed pipe in the process of bending and flattening the pipe by designing the connecting components, the stamping forming module and the sliding extrusion module, which not only ensures the overall production and processing efficiency, but also ensures the overall production and processing accuracy, and is suitable for large-scale continuous production and processing; (3) The present invention can play a stable supporting and positioning role for the placed pipe in the loading stage by designing the support ejection module. At the same time, after the processing is completed, the ejection seat can be moved upward under the elastic reaction force of the third reset spring, so that the formed bent pipe after processing can be ejected from the lower forming groove, making it more convenient to unload.

The lower forming module 1 includes a lower die base 101. A lower forming groove 102 is opened at the top center of the lower die base 101. Both ends of the lower forming groove 102 are respectively opened with a through residual material punching hole 103 and an inner punching hole 104, and both sides of the bottom of the lower die base 101 are opened with corresponding waste discharge grooves 105. The lower forming groove 102 opened on the lower die base 101 can cooperate with the upper forming groove 203 opened at the bottom center of the upper die base 201 to complete the alignment. The bending and forming of the pipe can be achieved by closing the lower forming module 1 and the upper forming module 2 to realize the one-time bending and forming of the pipe and the flattening of the connecting parts at both ends of the pipe. In addition, both ends of the lower forming groove 102 are respectively provided with a penetrating residual material punching hole 103 and an inner punching hole 104. After the pipe is bent and flattened, the punching processing of the flattened parts at both ends can be completed by two groups of stamping forming modules 6, so that the pipe can be processed and formed in one time to form the final formed bent pipe 9; the waste discharge grooves 105 opened on both sides of the bottom of the lower mold base 101 are used to discharge excess waste generated after punching.

[0049] Regarding the upper molding module 2, refer to Figures 1-10 The upper forming module 2 includes an upper die base 201, and two first limiting holes 202 matching the corresponding limiting rods 3 are provided at both ends of the upper die base 201. An upper forming groove 203 is provided at the bottom center of the upper die base 201, and a limiting sliding hole 204 and a limiting circular hole 205 are respectively provided at both ends of the upper forming groove 203. A support block 206 is fixedly connected to the top center of the upper die base 201, and a guide column 207 is fixedly connected to the top center of the support block 206. Guide rods 208 are fixedly connected to both sides of the top of the upper die base 201, and the top ends of the two guide rods 208 are threadedly connected to the limiting nuts 209. The bottom center of the upper die base 201 The upper forming groove 203 opened in the center can cooperate with the lower forming groove 102 during the mold closing process, thereby completing the one-time bending and forming of the pipe and the flattening of the connecting parts at both ends of the pipe; the limiting sliding holes 204 and the limiting circular holes 205 opened at the ends of the upper forming groove 203 can play a sliding limiting role in the installation of the stamping forming module 6, thereby ensuring the processing accuracy of the stamping forming module 6; the design of the two guide columns 207 can make the entire upper forming module 2 and the connecting component 4 form a linkage structure, and in the process of the connecting component 4 rising and resetting, it can also drive the upper forming module 2 to reset for subsequent unloading.

[0050] Furthermore, in this embodiment, the first return spring 5 is sleeved on the outer wall of the guide column 207. During the processing, the piston rod of the hydraulic drive unit will drive the connecting component 4 to move downward. During this process, the connecting component 4 will squeeze the first return spring 5 downward, and then drive the entire upper forming module 2 to close the mold downward, so as to utilize the mutual cooperation of the lower forming module 1 and the upper forming module 2 to first complete the bending of the pipe and the flattening of the two ends. When the pipe processing is completed and the hydraulic drive unit is reset, the elastic reaction force of the first return spring 5 will drive the connecting component 4 and the sliding extrusion module 7 to reset.

[0051] For connection components 4, refer to Figure 1-Figure 5 as well as Figure 11 , two limiting rods 3 are fixedly connected to both sides of the top of the lower forming module 1, and a connecting component 4 is slidably connected between the two groups of limiting rods 3. The connecting component 4 includes a connecting frame 401 sleeved between the two groups of limiting rods 3, and the corners of the connecting frame 401 are provided with second limiting holes 402 for the corresponding limiting rods 3 to pass through. A guide hole 403 for the guide column 207 to pass through is provided at the center of the connecting frame 401. Two third limiting holes 404 for the corresponding guide rods 208 to pass through are also provided on both sides of the connecting frame 401. Extrusion columns 405 are fixedly connected to both sides of the bottom of the connecting frame 401, and connecting seats 406 are fixedly connected to both sides of the top of the connecting frame 401. The connecting component 4 is mainly used for the connection and transition between the hydraulic drive unit and the upper forming module 2. The two connecting seats 406 are connected to the hydraulic The piston rod of the hydraulic drive unit is connected (not shown in the figure). During actual use, the piston rod of the hydraulic drive unit drives the entire connecting assembly 4 to rise and fall. In the process of bending and flattening the pipe, the connecting frame 401 will first squeeze the first return spring 5 by moving downward, and then drive the entire upper forming module 2 to close the mold downward. When the upper forming module 2 is closed downward, the connecting frame 401 will continue to move downward, so that the extrusion columns 405 on both sides of the bottom of the connecting frame 401 simultaneously squeeze the sliding extrusion module 7 downward, and finally the extrusion sliding extrusion module 7 drives the two groups of stamping forming modules 6 to complete the punching processing of the formed pipe. After the processing is completed, the connecting frame 401 will also drive the upper forming module 2 to reset during the rising and resetting process, thereby realizing automatic mold opening for subsequent unloading.

[0052] Stamping modules 6 are slidably installed on both sides of the top of the upper forming module 2, and a sliding extrusion module 7 is slidably installed on the upper forming module 2. During the downward pressing process, the two groups of stamping modules 6 can be squeezed downward at the same time to complete the stamping forming of the two ends of the pipe.

[0053] For stamping die set 6, refer to Figure 12-13The stamping forming module 6 includes a fixed block 601, the bottom of the fixed block 601 is fixedly connected to a punching block 602 and a punching column 603, the punching block 602 and the punching column 603 are respectively slidably limited in the corresponding limiting sliding hole 204 and the limiting circular hole 205, the outer wall of the punching column 603 is also sleeved with a second return spring 604, the top center of the punching column 603 is fixedly connected to a fixed column 605, the top of the fixed column 605 is designed with an inclined surface, and the stamping forming module 6 is mainly used for bending pipes and flattening. The punching processing at both ends of the formed pipe, in actual operation, when the sliding extrusion module 7 moves downward, the sliding extrusion module 7 will simultaneously squeeze the fixed column 605 downward, and then drive the punching block 602 and the punching column 603 to quickly perform shearing movement downward, so that the remaining material at the end of the flattened pipe can be sheared and punched to form the final formed bend 9. When the sliding extrusion module 7 rises and resets, under the elastic reaction force of the second reset spring 604, the entire stamping forming module 6 will be pushed up and reset.

[0054] Regarding the sliding extrusion die 7, refer to Figure 1-Figure 5 as well as Figure 14 The sliding extrusion module 7 includes a fixed plate 701 that slides on the outer walls of the two guide rods 208. A fourth limiting hole 702 is provided in the middle of the fixed plate 701 for the guide column 207 to pass through. Two fifth limiting holes 703 are also provided on both sides of the fixed plate 701 for the corresponding guide rods 208 to pass through. Extrusion blocks 704 are fixedly connected to both ends of the fixed plate 701. The bottoms of the two extrusion blocks 704 are provided with limiting grooves 705 that match the corresponding fixed columns 605. The sliding extrusion module 7 is mainly provided with a downward extrusion force by the connecting component 4, and when the sliding extrusion module 7 moves downward, the extrusion blocks 704 fixedly connected at both ends of the fixed plate 701 will simultaneously squeeze the stamping forming module 6 downward. At this time, the fixed column 605 will slide in the limiting groove 705 and continue to decrease in height, and finally complete the punching processing operation.

[0055] Regarding the support ejection module 8, refer to Figure 1-Figure 5 as well as Figure 15, a support ejection module 8 is also installed at the bottom center of the lower forming module 1, which is used to support the pipe before processing and eject the pipe after processing. The support ejection module 8 includes an ejection seat 801 slidably mounted in the U-shaped mounting hole 106, and support grooves 802 are provided on both sides of the top of the ejection seat 801. A sixth limiting hole 803 is provided at the bottom center of the ejection seat 801, and a support column 804 is slidably connected in the sixth limiting hole 803. The bottom of the support column 804 is fixedly connected to a mounting plate 805, and the outer wall of the support column 804 is sleeved with a third return spring 806. In the loading stage, due to the lifting effect of the third return spring 806, the height of both sides of the top of the ejection seat 801 will exceed the level of the lower forming groove 102 Height, at this time, the operator can place the pipe to be processed horizontally in the two supporting grooves 802, with the two ends roughly symmetrical. At this time, the ejector seat 801 can provide stable support and positioning for the placed pipe. In the subsequent mold closing process, the ejector seat 801 will also ensure that the pipe will not rotate or deflect, thereby ensuring the processing accuracy and quality. After the processing is completed, during the rising and resetting process of the upper forming module 2, the third return spring 806 loses its downward extrusion force. At this time, under the elastic reaction force of the third return spring 806, the ejector seat 801 can move upward again, so that the formed elbow 9 after processing can be ejected from the lower forming groove 102, which is more convenient for unloading.

[0056] Furthermore, in this embodiment, the ejector seat 801 is designed in a U-shaped structure, and the mounting plate 805 is fixed to the bottom of the U-shaped mounting hole 106 by a plurality of fixing screws. The ejector seat 801 with a U-shaped structure can form a more stable support structure. At the same time, its overall structural design is also more convenient for quick installation, fixation and daily inspection and maintenance.

[0057] The working principle of this embodiment is as follows. During processing, the operator places the pipe to be processed horizontally in the two supporting grooves 802, keeping the two ends roughly symmetrical, and then the piston rod of the hydraulic drive unit drives the entire connecting assembly 4 to descend. In the process of bending and flattening the pipe, the connecting frame 401 will first squeeze the first return spring 5 by moving downward, thereby driving the entire upper forming module 2 to close the mold downward. When the upper forming module 2 is closed downward, the connecting frame 401 will continue to move downward, thereby causing the extrusion columns 405 on both sides of the bottom of the connecting frame 401 to squeeze the sliding extrusion module 7 downward at the same time. Finally, the extrusion sliding extrusion module 7 drives the two sets of stamping forming modules 6 to complete the punching processing of the formed pipe. After the processing is completed, the connecting frame 401 will also drive the upper forming module 2 to reset during the rising and resetting process;

[0058] During the upward reset process of the upper forming module 2, the third reset spring 806 loses its downward extrusion force. At this time, under the elastic reaction force of the third reset spring 806, the ejection seat 801 can move upward, so that the formed elbow 9 after processing can be ejected from the lower forming groove 102. At this time, the operator can conveniently carry out unloading.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
