Description

Technical Field

[0001] This utility model relates to the field of pipe diameter reduction technology, specifically to a pipe diameter reduction device for the production of welding gun components. Background Technology

[0002] The pipe reduction device for welding torch components can effectively reduce the diameter of the pipe to meet the precision and quality requirements of the welding torch components. This reduction device adopts advanced technology and design to ensure that the size and shape of the pipe remain consistent during the reduction process, thereby improving the overall performance and service life of the welding torch components.

[0003] In existing technologies, the diameter and length of the reduced-diameter section of the pipe after traditional pipe reduction deviate greatly from the design value, or the size consistency of products in the same batch is poor. In addition, micro-cracks appear in the transition section of the reduced-diameter section, or the overall hardness and tensile strength of the pipe are reduced. Therefore, we propose a pipe reduction device for the production of welding gun components. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a pipe diameter reduction device for the production of welding gun components, which solves the technical problem of stable diameter reduction in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a pipe diameter reduction device for the production of welding torch components, comprising: a sliding wheel, a fixed platform fixedly connected to the top of the sliding wheel, an oil tank fixedly connected to the top of the fixed platform, a worktable fixedly connected to the top of the oil tank, a bracket fixedly connected to the top of the worktable, and a diameter reduction mechanism provided on the side of the bracket; The reducing mechanism includes a support plate, the bottom of which is fixedly connected to the inner bottom wall of the workbench. A hydraulic pump is fixedly connected to the side of the support plate, and an oil suction pipe and an oil pipe pass through the side of the hydraulic pump. A hydraulic telescopic lever is fixedly connected to the end of the oil pipe away from the hydraulic pump. A push rod is fixedly connected to the retracted end of the hydraulic telescopic lever. A housing is fixedly connected to the side of the support. A sliding block is fixedly connected to the end of the push rod away from the hydraulic telescopic lever. The sliding block is slidably connected to the inner wall of the housing, and a clamping block is slidably connected to the inner wall of the sliding block.

[0006] For example, in at least one embodiment of this utility model, a pipe reduction device for producing welding torch components further includes: eight clamping blocks fixedly connected to the inner wall of the clamping block, arranged in a circumferential array on the inner wall of the clamping block. The eight clamping blocks fixed to the inner wall of the clamping block, arranged in a circumferential array, can uniformly clamp the pipe from multiple points around its outer periphery, preventing the pipe from shifting or deforming due to uneven force during the reduction process, ensuring the roundness and dimensional consistency of the pipe after reduction, and improving the processing quality of the welding torch component pipe.

[0007] The inner wall of the housing is provided with a sliding groove, and the circumferential surface of the sliding block is located on the displacement trajectory of the sliding groove. The sliding groove on the inner wall of the housing provides precise displacement trajectory restriction for the sliding block, preventing the sliding block from deviating or getting stuck during movement, ensuring that the sliding block drives the clamping block to perform a stable diameter reduction action, and further improving the stability and diameter reduction accuracy of the diameter reduction process.

[0008] The number of oil pipes and hydraulic telescopic rods is two, and they are symmetrical to each other along the vertical central axis of the outer shell. A control module is fixedly connected to the top of the worktable. The two oil pipes and hydraulic telescopic rods, which are symmetrical along the vertical central axis of the outer shell, can provide symmetrical driving force for the push rod, avoiding tilting of the push rod due to force on one side, and ensuring smooth movement of the sliding block. The control module on the top of the worktable can realize automated control of components such as hydraulic pumps, reduce human operation errors, and improve the ease of operation and diameter reduction efficiency of the device.

[0009] The circumferential surface of the push rod is slidably connected to the side of the housing, and a fixing bracket is fixedly connected to the side of the worktable. This structure, where the circumferential surface of the push rod is slidably connected to the side of the housing, ensures smooth movement of the push rod and provides radial limiting to reduce its wobbling. The fixing bracket on the side of the worktable provides support for subsequent components.

[0010] According to another aspect, at least one embodiment of the present invention also provides a pipe diameter reduction device for the production of welding torch components, comprising: an easily detachable protective mechanism provided on the top of the oil tank, the easily detachable protective mechanism including a first sliding plate, the bottom of the first sliding plate being fixedly connected to the inner bottom wall of the workbench, a second sliding plate being fixedly connected to the inner bottom wall of the workbench, a sliding groove being provided on the side of both the first and second sliding plates, a protective plate being slidably connected to the inner side wall of the sliding groove, a handle being fixedly connected to the top of the protective plate, a card seat being fixedly connected to the inner bottom wall of the workbench, a connecting rod being slidably connected to the side of the card seat, a card block being fixedly connected to the end of the connecting rod, a compression spring being fixedly connected to the side of the card block, and the end of the compression spring away from the card block being fixedly connected to the inner side wall of the card seat.

[0011] For example, in at least one embodiment of this utility model, a pipe diameter reduction device for welding torch component production further includes: a connecting column fixedly connected to the side of the protective plate, and a release block slidably connected to the circumferential surface of the connecting column. The cooperation between the connecting column and the release block on the side of the protective plate optimizes the connection and unlocking process between the protective plate and the mounting bracket. The sliding design of the release block reduces the frictional resistance between the connecting column and the mounting bracket, making the disassembly of the protective plate smoother, further improving the ease of use of the easily disassembled protective mechanism, and shortening maintenance time.

[0012] The number of connecting rods is two, and they are symmetrical to each other along the vertical central axis of the clamping block. A hydraulic disassembly device is fixedly connected to the side of the fixing frame. The two connecting rods, which are symmetrical along the vertical central axis of the clamping block, can balance the force on the clamping block, prevent the clamping block from tilting due to force on one side, ensure that the guard plate is firmly fixed, and prevent the protective mechanism from loosening. The hydraulic disassembly device on the side of the fixing frame can disassemble the clamping block assembly on the device.

[0013] The side of the card holder has a cylindrical groove, and the circumferential surface of the connecting post lies on the displacement trajectory of the cylindrical groove. The cylindrical groove on the side of the card holder provides a precise displacement trajectory for the connecting post, ensuring that the connecting post can be accurately inserted into the card holder and cooperate with the card block, avoiding the failure of the protective plate fixation due to misalignment of the connecting post, and ensuring the protective effect.

[0014] The number of sliding wheels is set to four, arranged in pairs and symmetrically about each other along the vertical central axis of the fixed platform. A protective plate is fixedly connected to the inner bottom wall of the worktable. The four sliding wheels, arranged symmetrically about the vertical central axis of the fixed platform, ensure that the device is subjected to balanced forces during movement, preventing the device from tilting due to a shift in the center of gravity and improving the stability of the device's movement. The protective plate on the inner bottom wall of the worktable protects the card holder and extends the service life of the easily detachable protective mechanism.

[0015] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the hydraulic pump in the diameter reduction mechanism continuously obtains hydraulic oil through the oil tank, providing stable power to the hydraulic telescopic lever and avoiding diameter reduction failure caused by power interruption. At the same time, the symmetrically distributed oil pipes and hydraulic telescopic lever provide symmetrical driving force to the push rod. Combined with the limiting effect of the outer shell on the push rod and sliding block, it ensures that the sliding block drives the clamping block to move smoothly, so that the pressure applied by the clamping block to the pipe is uniform, effectively preventing the pipe from shifting or deforming due to uneven force, ensuring the roundness and dimensional consistency of the pipe after diameter reduction, and improving the processing accuracy of the welding torch component pipe.

[0016] In this utility model, the easily detachable protective mechanism can completely cover the top and sides of the oil tank when the protective plate is fixed, effectively preventing dust in the air, metal shavings in the workshop, coolant and other impurities from entering the oil tank. This avoids impurities from mixing into the hydraulic oil and causing blockage or wear of components such as hydraulic pumps and oil pipes, thus ensuring the cleanliness and operational stability of the entire hydraulic system.

Detailed Implementation The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0025] like Figures 1-6 As shown, it illustrates a pipe diameter reduction device for welding gun component production in one embodiment of the present invention, including: a sliding wheel 1, a fixed platform 2 fixedly connected to the top of the sliding wheel 1, an oil tank 3 fixedly connected to the top of the fixed platform 2, a workbench 4 fixedly connected to the top of the oil tank 3, a support 8 fixedly connected to the top of the workbench 4, and a diameter reduction mechanism 5 provided on the side of the support 8. The reducing mechanism 5 includes a support plate 51. The bottom of the support plate 51 is fixedly connected to the inner bottom wall of the workbench 4. A hydraulic pump 52 is fixedly connected to the side of the support plate 51. An oil suction pipe 53 passes through the side of the hydraulic pump 52. An oil pipe 54 passes through the side of the hydraulic pump 52. A hydraulic telescopic rod 55 is fixedly connected to the end of the oil pipe 54 away from the hydraulic pump 52. A push rod 510 is fixedly connected to the retracted end of the hydraulic telescopic rod 55. A housing 56 is fixedly connected to the side of the bracket 8. A sliding block 57 is fixedly connected to the end of the push rod 510 away from the hydraulic telescopic rod 55. The sliding block 57 is slidably connected to the inner wall of the housing 56. A clamping block 58 is slidably connected to the inner wall of the sliding block 57.

[0026] In some examples, clamping blocks 59 are fixedly connected to the inner wall of the clamping block 58. There are eight clamping blocks 59, which are distributed in a circumferential array on the inner wall of the clamping block 58. The eight clamping blocks 59 fixed to the inner wall of the clamping block 58 are distributed in a circumferential array, which can evenly clamp the pipe from multiple points on the outer periphery of the pipe, avoid the pipe from shifting or deforming due to uneven force during the diameter reduction process, ensure the roundness and dimensional consistency of the pipe after diameter reduction, and improve the processing quality of the pipe of the welding torch component.

[0027] The inner wall of the outer casing 56 is provided with a groove, and the circumferential surface of the sliding block 57 is located on the displacement trajectory of the groove. The groove on the inner wall of the outer casing 56 provides precise displacement trajectory restriction for the sliding block 57, preventing the sliding block 57 from deviating or jamming during movement, ensuring that the sliding block 57 drives the clamping block 58 to perform a stable diameter reduction action, and further improving the stability and diameter reduction accuracy of the diameter reduction process.

[0028] There are two oil pipes 54 and two hydraulic telescopic rods 55, which are symmetrical to each other along the vertical central axis of the outer shell 56. The control module 10 is fixedly connected to the top of the worktable 4. The two oil pipes 54 and hydraulic telescopic rods 55, which are symmetrical along the vertical central axis of the outer shell 56, can provide symmetrical driving force for the push rod 510, avoid the push rod 510 from tilting due to force on one side, and ensure the smooth movement of the sliding block 57. The control module 10 on the top of the worktable 4 can realize the automated control of components such as the hydraulic pump 52, reduce human operation error, and improve the ease of operation and diameter reduction efficiency of the device.

[0029] The circumferential surface of the push rod 510 is slidably connected to the side of the housing 56, and a fixing bracket 9 is fixedly connected to the side of the worktable 4. The structure in which the circumferential surface of the push rod 510 is slidably connected to the side of the housing 56 ensures the smooth movement of the push rod 510 and also provides radial limiting for the push rod 510, reducing the wobbling of the push rod 510. The fixing bracket 9 on the side of the worktable 4 provides support for subsequent components.

[0030] For example, such as Figures 1-6As shown, before the start of work, the reducing mechanism 5 is in its initial state. The hydraulic pump 52 is fixed to the side of the support plate 51. One end of the oil pipe 53 is connected to the inside of the oil tank 3, and the other end passes through the side of the hydraulic pump 52. The two ends of the oil pipe 54 are connected to the hydraulic pump 52 and the hydraulic telescopic rod 55 respectively. The telescopic end of the hydraulic telescopic rod 55 is in the retracted state, which drives the push rod 510 to retract. The sliding block 57 at the end of the push rod 510 is located in the initial position of the sliding groove on the inner side wall of the outer shell 56. The clamping block 58 on the inner wall of the sliding block 57 is in the open state. The welding gun component pipe to be processed is placed inside the clamping block 58. The clamping block 59 is not in contact with the pipe yet. The operator starts the reducing mechanism 5 through the control module 10 on the top of the workbench 4: the hydraulic pump 52 is powered on and runs, and draws hydraulic oil from the oil tank 3 through the oil pipe 53. After internal pressurization, the high-pressure hydraulic oil is synchronously delivered to the corresponding hydraulic telescopic rod 55 through the symmetrical oil pipes 54 on both sides. Because the oil pipes 54 are symmetrically distributed, high-pressure hydraulic oil can enter the hydraulic telescopic rods 55 on both sides evenly, avoiding power deviation caused by uneven hydraulic oil supply on one side. The high-pressure hydraulic oil pushes the telescopic end of the hydraulic telescopic rod 55 to extend outward, and the push rod 510, which is fixedly connected to the telescopic end, moves in a straight line towards the pipe. The circumferential surface of the push rod 510 is slidably connected to the side of the housing 56. The housing 56 provides radial limiting for the push rod 510, preventing it from tilting or shaking during movement. As the push rod 510 moves, the sliding block 57 fixed at its end slides synchronously in the groove on the inner wall of the housing 56. The inner wall of the sliding block 57 pushes the clamping block 58 to move towards the pipe. Finally, the clamping block 59 on the inner wall of the clamping block 58 fits against the outer circumference of the pipe and applies uniform pressure to the pipe, causing the pipe diameter to gradually shrink to the target size, completing the diameter reduction process. Once the pipe diameter reduction reaches the preset size, the control module 10 issues a reset command: the hydraulic pump 52 reverses its rotation, drawing back the high-pressure hydraulic oil in the hydraulic telescopic lever 55 through the oil pipe 54. The telescopic end of the hydraulic telescopic lever 55 retracts, causing the push rod 510, sliding block 57, and clamping block 58 to reset synchronously. The clamping block 58 and clamping block 59 disengage from the pipe, and the operator removes the processed pipe. The diameter reduction mechanism 5 returns to its initial standby state, awaiting the next work command.

[0031] like Figures 1-6As shown, this invention illustrates a pipe diameter reduction device for welding torch component production in another embodiment of the present invention. The top of the oil tank 3 is equipped with an easily detachable protective mechanism 6. The easily detachable protective mechanism 6 includes a first sliding plate 61, the bottom of which is fixedly connected to the inner bottom wall of the workbench 4. A second sliding plate 62 is fixedly connected to the inner bottom wall of the workbench 4. Both the first sliding plate 61 and the second sliding plate 62 have sliding grooves on their sides. A protective plate 63 is slidably connected to the inner wall of the sliding groove. A handle 64 is fixedly connected to the top of the protective plate 63. A card seat 66 is fixedly connected to the inner bottom wall of the workbench 4. A connecting rod 67 is slidably connected to the side of the card seat 66. A card block 68 is fixedly connected to the end of the connecting rod 67. A compression spring 69 is fixedly connected to the side of the card block 68. The end of the compression spring 69 away from the card block 68 is fixedly connected to the inner wall of the card seat 66.

[0032] In some examples, a connecting post 610 is fixedly connected to the side of the guard plate 63, and a release block 611 is slidably connected to the circumferential surface of the connecting post 610. The cooperation between the connecting post 610 and the release block 611 on the side of the guard plate 63 can optimize the connection and unlocking process between the guard plate 63 and the card holder 66. The sliding design of the release block 611 can reduce the frictional resistance between the connecting post 610 and the card holder 66, making the disassembly of the guard plate 63 smoother, further improving the ease of use of the easy-to-disassemble protective mechanism 6, and shortening the maintenance time.

[0033] There are two connecting rods 67, which are symmetrical about each other along the vertical central axis of the locking block 68. A hydraulic disassembly device 11 is fixedly connected to the side of the fixing frame 9. The two connecting rods 67, which are symmetrical about the vertical central axis of the locking block 68, can balance the force on the locking block 68, prevent the locking block 68 from tilting due to force on one side, ensure that the guard plate 63 is firmly fixed, and prevent the protective mechanism from loosening. The hydraulic disassembly device 11 on the side of the fixing frame 9 can disassemble the clamping block 59 assembly on the device.

[0034] The side of the card holder 66 has a cylindrical groove, and the circumferential surface of the connecting post 610 is located on the displacement trajectory of the cylindrical groove. The cylindrical groove on the side of the card holder 66 provides a precise displacement trajectory for the connecting post 610, ensuring that the connecting post 610 can be accurately inserted into the card holder 66 to cooperate with the card block 68, avoiding the failure of the protective plate 63 to be fixed due to misalignment of the connecting post 610, and ensuring the protective effect.

[0035] The number of sliding wheels 1 is set to four, arranged in pairs and symmetrically about each other along the vertical central axis of the fixed platform 2. A protective plate 7 is fixedly connected to the inner bottom wall of the worktable 4. The four sliding wheels 1, which are symmetrical about each other along the vertical central axis of the fixed platform 2, can make the force on the device balanced during movement, prevent the device from tilting due to the shift of the center of gravity, and improve the stability of the device movement. The protective plate 7 on the inner bottom wall of the worktable 4 can protect the card seat 66 and extend the service life of the easily detachable protective mechanism 6.

[0036] For example, such as Figures 1-6 As shown, in the initial protective state, the release block 611, as an intermediate transmission component between the locking block 68 and the connecting post 610, can evenly transmit the elastic force of the compression spring 69 to the connecting post 610, avoiding localized wear caused by the locking block 68 directly contacting the connecting post 610, while enhancing the fixing stability of the connecting post 610; even if the device generates slight vibration during operation, the release block 611 can prevent the connecting post 610 from loosening by tightly fitting with the locking block 68, effectively blocking impurities from entering the oil tank 3, ensuring the clean operation of components such as the hydraulic pump 52 and oil pipe 54. When unlocking, the release block 611 converts the upward pulling force of the guard plate 63 into the lateral moving force of the locking block 68 through the inclined guide surface, without requiring the operator to push the connecting post 610. The lever 67 can be unlocked simply by pulling the handle 64, simplifying the operation. Compared to traditional structures, it avoids the laborious manual pushing of the lever 67 and reduces frictional resistance between components, making the unlocking process smoother, significantly shortening maintenance preparation time, and reducing labor intensity. During reset, the inclined guide surface of the release block 611 provides precise lateral movement guidance for the locking block 68, ensuring that the locking block 68 accurately resets under the action of the compression spring 69 and fits against the release block 611. At the same time, the release block 611 reduces direct friction between the connecting post 610 and the locking seat 66, extending the service life of each component. Even with long-term high-frequency use, it can maintain a stable transmission effect and avoid protection failure caused by component wear.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
