Description

Technical Field

[0001] This invention belongs to the field of pin bushing production and processing technology, and particularly relates to an intelligent rolling and welding system for pin bushings. Background Technology

[0002] Pin bushings are key components widely used in mechanical connections, mainly serving to reduce friction, buffer vibration, and extend equipment life. They are commonly found in fields such as engineering machinery, automobile manufacturing, and aerospace. Traditional pin bushing manufacturing processes mainly include casting, machining, and sheet metal rolling and welding. Among these, sheet metal rolling and welding has become the mainstream production method due to its advantages such as high material utilization, fast production efficiency, and good product strength. However, existing pin bushing rolling and welding equipment has many technical bottlenecks: First, traditional equipment can usually only adapt to the production of a single specification of product. When it is necessary to change pin bushings of different diameters, the machine must be stopped to replace the entire set of molds and rolling components, resulting in low production efficiency and low equipment utilization. Second, the unloading process of existing equipment relies heavily on manual intervention. After high-temperature welding, it is necessary to wait for cooling before unloading, which not only prolongs the production cycle but also increases the safety risks for operators.

The lower winding block and the outer cylinder are slidably connected to the inner cylinder. Insertion holes are provided on both the outer cylinder and the inner cylinder. Fixing bolts pass through the insertion holes and are threadedly fixed with nuts.

[0008] Furthermore, the upper winding assembly includes a support frame, which is fixed on the main support frame. The support frame is fixedly connected to the second motor, and the output end of the second motor is connected to the second lead screw. The transport assembly slides on the support frame, and the second lead screw is threadedly connected to the transport assembly. The support frame is symmetrically provided with two slide grooves, and two slide carriages are slidably connected in the two slide grooves respectively. A second support box is fixed on the slide carriage, and a second slider is slidably connected in the second support box. A first spring is provided between the second support box and the second slider. The slide carriage is rotatably connected to a rotating wheel, and the rotating wheel is provided with multiple slots.

[0013] The advantages of this invention are: When the intelligent rolling and welding system for pin bushings is in operation, a flat metal material is first placed on a transport component. The transport component then conveys the sheet metal to a preset position between the adjustable mold core component and the lower rolling component. The lower rolling component rises and initially closes with the adjustable mold core component, causing the middle of the sheet metal to bend and deform under pressure, initially conforming to the outer surface contour of the adjustable mold core component. The upper rolling component moves towards the adjustable mold core component and fully closes with it. The two ends of the sheet metal are finally bent and formed under pressure, creating a complete cylindrical structure that surrounds the outside of the adjustable mold core component. The welding component then precisely welds the seam of the roll, completing the manufacturing of the pin bushing. This system automates the entire process from sheet metal conveying to rolling and welding, significantly improving production efficiency, reducing manual operation difficulty, and ensuring product consistency and quality stability.

Detailed Implementation

[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: As Figures 1-15As shown, the intelligent rolling and welding system for pin bushings includes a support frame 1, an adjustable mold core assembly 6 is installed on the support frame 1, a lower rolling assembly 5 is provided below the adjustable mold core assembly 6, upper rolling assemblies 4 are provided on both sides of the adjustable mold core assembly 6, a transport assembly 3 is slidably connected to the upper rolling assembly 4, and a welding assembly is installed on the support frame 1. Both the upper winding assembly 4 and the lower winding assembly 5 are mounted on the support frame 1; The working principle of the above technical solution is as follows: When the intelligent rolling and welding system for pin bushings is working, the flat metal material is first placed on the transport component 3. The transport component 3 transports the sheet metal to a preset position between the adjustable mold core component 6 and the lower rolling component 5. The lower rolling component 5 rises and achieves preliminary mold closing with the adjustable mold core component 6, causing the middle part of the sheet metal to bend and deform under pressure, initially conforming to the outer surface contour of the adjustable mold core component 6. The upper rolling component 4 moves towards the adjustable mold core component 6 and achieves complete mold closing with the adjustable mold core component 6. The two ends of the sheet metal complete the final bending and forming under pressure, forming a complete cylindrical structure surrounding the outside of the adjustable mold core component 6. The welding component performs precise welding at the roll joint, completing the manufacturing of the pin bushing. This system realizes full automation from sheet metal transportation to rolling and forming to welding, greatly improving production efficiency, reducing the difficulty of manual operation, and ensuring product consistency and quality stability.

[0018] Example 2: Figures 1-15 As shown, the adjustable mold core assembly 6 includes an inner mold core 601, which is fixed to the support frame 1 by a locking nut 602. Multiple outer mold cores 603 are sleeved on the outer side of the inner mold core 601. The inner mold core 601 and the multiple outer mold cores 603 are concentrically arranged. Both the inner mold core 601 and the outer mold cores 603 are provided with curved grooves 604 on their outer sides. A sliding column 605 is provided in the outer mold core 603, and the sliding column 605 slides in the curved groove 604. The inner mold core 601 is rotatably connected to a rotating column 606, and a top plate 607 is slidably connected inside the rotating column 606. The rotating column 606 is threadedly connected to a locking screw 608. The lower end of the locking screw 608 abuts against the top plate 607, and the front end of the top plate 607 abuts against the end of the outer mold core 603. The end of the inner mold core 601 is provided with a demolding component. The curved groove 604 on the inner mold core 601 is provided at the lower end of the inner mold core 601; The working principle of the above technical solution is as follows: When producing pin bushings with a smaller diameter, only the inner mold core 601 is used. After the sheet metal is formed by rolling, it is directly fitted onto the outer surface of the inner mold core 601. When producing pin bushings with a larger diameter, the outer mold core 603 is first fitted onto the outside of the inner mold core 601. Initial positioning is achieved through the cooperation of the sliding column 605 and the curved groove 604. In specific operation, the outer mold core 603 is slid into the inner mold core 601 from the end, so that the sliding column 605 enters along the straight part of the curved groove 604. Then, the outer mold core 603 is rotated, so that the sliding column 605 slides into the bending locking area of ​​the curved groove 604, realizing the connection between the outer mold core 603 and the inner mold core 601. For initial locking, to enhance the locking effect, loosen the locking screw 608, move the top plate 607 upwards to contact the end of the outer mold core 603, and then tighten the locking screw 608 to make the top plate 607 align and press against the end face of the outer mold core 603, forming an axial lock to prevent the outer mold core 603 from axially displacing during the rolling process. When a larger diameter is required, a second outer mold core 603 can be fitted outside the first outer mold core 603 and locked in the same way. This modular design allows the same set of equipment to flexibly adapt to the production needs of various specifications of products without replacing the entire set of molds, which greatly reduces equipment investment costs, shortens product changeover time, and improves equipment utilization.

[0019] Example 3: Figures 1-15 As shown, the demolding assembly includes a bending frame 614, which is slidably connected to the support frame 1. One end of the bending frame 614 is fixedly connected to the cylinder 615, and the other end of the bending frame 614 is fixedly connected to the push frame 609. The push frame 609 is fixedly connected to the bracket 610, and the bracket 610 is slidably connected to the moving column 611. A slider 613 is slidably connected inside the push frame 609. The slider 613 is fixedly connected to the moving column 611. A spring 612 is provided between the slider 613 and the bracket 610. The spring 612 is sleeved on the outside of the moving column 611, and the front end of the slider 613 abuts against the long groove 616 provided on the outside of the outer mold core 603. During the rolling and welding process, the slider 613 is located at the inner end of the long groove 616, which does not affect the rolling and welding work. The working principle of the above technical solution is as follows: After the rolling and welding are completed, the pin bushing is tightly fitted onto the outer surface of the mold core assembly. Traditional unloading methods often require manual intervention or complex mechanisms. In this design, when the inner mold core 601 is used alone, the front end of the slider three 613 directly abuts against the long groove 616 set on the outer surface of the inner mold core 601; when the outer mold core 603 is fitted outside the inner mold core 601, the slider three 613 slides inside the pusher 609, compressing the spring two 612, so that the front end of the slider three 613 adaptively abuts against the long groove 616 set on the outer surface of the outer mold core 603. During unloading, the cylinder three 615 is activated, pushing the bending frame 61 4. Sliding along the support frame 1, driving the pusher 609, bracket 3 610 and slider 3 613 to move forward as a whole. At this time, slider 3 613 slides in the long groove 616, and its front contact surface pushes the formed pin bushing to move axially, realizing automatic unloading. The design of spring 2 612 enables slider 3 613 to automatically adjust its position according to the mold core diameter, ensuring that it can effectively contact and push the pin bushing when producing products of different specifications. This adaptive unloading mechanism does not require manual intervention or readjustment, simplifies the operation process, improves the degree of automation, and protects the product surface from damage, ensuring the consistency of product quality.

[0020] Example 4: Figures 1-15 As shown, the lower winding assembly 5 includes a second cylinder 501, which is fixed on the support frame 1. The output end of the second cylinder 501 is fixedly connected to the lower bracket 502. The lower bracket 502 is fixedly connected to the lower winding block 503. Multiple inner winding blocks 504 are placed on the upper end of the lower winding block 503. An outer cylinder 505 is fixed to the lower end of the lower winding block 503. An inner cylinder 506 is fixed to the lower end of the inner winding block 504. The lower winding block 503 and the outer cylinder 505 are slidably connected to the inner cylinder 506. Insertion holes are provided on both the outer cylinder 505 and the inner cylinder 506. Fixing bolts 507 pass through the insertion holes and are threadedly fixed with nuts. The working principle of the above technical solution is as follows: When producing larger diameter pin bushings, cylinder 2 501 is activated, pushing the lower support 502 upward, which in turn causes the lower coiling block 503 to rise. Its upper surface contacts the outer surface of the adjustable mold core assembly 6, applying pressure to the middle of the sheet metal to cause it to bend and deform. When producing smaller diameter pin bushings, it is necessary to replace the appropriate inner coiling block 504. At this time, the fixing bolt 507 is loosened, and the inner coiling block 504 is placed on top of the lower coiling block 503. At the same time, the inner cylinder 506 at the lower end of the inner coiling block 504 is inserted into the outer cylinder 505 at the lower end of the lower coiling block 503. Precise positioning is achieved through the cooperation of the inner and outer cylinders, and then fixed... Bolt 507 passes through the corresponding insertion hole and is tightened, so that the inner roll block 504 is firmly fixed on the lower roll block 503. The upper surface contour of the inner roll block 504 matches the smaller diameter mold core assembly, which can provide appropriate bending pressure to the sheet metal. This modular design allows the lower roll assembly 5 to quickly adapt to the production needs of products of different specifications without replacing the entire lower roll mechanism, reducing equipment investment costs and changeover time. The cooperation between the inner cylinder 506 and the outer cylinder 505 not only provides precise positioning, but also enhances the structural strength of the inner roll block 504, ensuring that no displacement or deformation occurs during high-pressure rolling, thus guaranteeing the stability of product forming quality.

[0021] Example 5: Figures 1-15 As shown, the upper winding assembly 4 includes a support frame 401, which is fixed on the main support frame 1. The support frame 401 is fixedly connected to the second motor 402. The output end of the second motor 402 is connected to the second lead screw 403. The transport assembly 3 slides on the support frame 401. The second lead screw 403 is threadedly connected to the transport assembly 3. The support frame 401 is symmetrically provided with two slide grooves 404. Two slide frames 405 are slidably connected in the two slide grooves 404 respectively. The second support box 406 is fixed on the slide frame 405. The second slider 408 is slidably connected in the second support box 406. A spring 407 is provided between the second support box 406 and the second slider 408. The slide frame 405 is rotatably connected to the rotating wheel 409. The rotating wheel 409 is provided with multiple slots 410. The front end of the second slider 408 is engaged in the slot 410. The rotating wheel 409 is fixedly connected to the central frame 411. Multiple upper rolling blocks 412 are installed on the central frame 411. Two slides 405 are fixedly connected to two racks 413 respectively. The racks 413 mesh with the gears 414 on the upper and lower sides. The gears 414 are connected to the output end of the motor 415. The motor 415 is fixed on the support frame 1. The working principle of the above technical solution is as follows: Multiple upper winding blocks 412 of different sizes are installed on the center frame 411. The inner surface contour of each upper winding block 412 matches a mold core assembly of a specific diameter. When a change in production specifications is required, the operator pulls the second slider 408 backward, overcoming the elastic force of the first spring 407, causing the front end of the second slider 408 to disengage from the slot 410 on the rotating wheel 409, thus releasing the lock on the rotating wheel 409. Subsequently, the rotating wheel 409 is rotated, causing the center frame 411 to rotate, selecting the upper winding block 412 that matches the current production specification, and turning it towards the position of the adjustable mold core assembly 6. After releasing the second slider 408, under the elastic force of the first spring 407, the front end of the second slider 408 automatically engages in the corresponding slot 410, moving the rotating wheel 409... 09 and center frame 411 are locked in the selected position. During the rolling process, motor 3 415 starts and drives gear 414 to rotate. Through the meshing transmission with the upper and lower racks 413, the two slides 405 move towards each other along the slide groove 404, driving the selected upper rolling block 412 to move towards the center and achieve mold closing with the adjustable mold core assembly 6. Pressure is applied to both ends of the sheet metal to make it completely bent and formed. This design allows a single set of equipment to flexibly adapt to the production of various specifications of products without replacing the entire upper rolling assembly, which greatly shortens the product changeover time and improves the equipment utilization rate. The cooperation between slider 2 408 and slot 410 provides a reliable locking mechanism to ensure that the upper rolling block 412 will not rotate unexpectedly during the high-pressure rolling process, thus ensuring the stability of the product forming quality.

[0022] Example 6: Figures 1-15 As shown, a protective cover 2 is installed on the rear side of the support frame 1; The working principle of the above technical solution is as follows: The protective cover 2 is installed on the rear side of the support frame 1. Its working principle is mainly reflected in two aspects: all-round safety protection and production environment optimization. In terms of safety protection, the protective cover 2 is made of high-strength transparent material, covering the entire working area, effectively isolating rotating parts, moving mechanisms and high-temperature welding areas, preventing operators from accidentally contacting dangerous parts, and avoiding mechanical injury and burn risks. In terms of environmental optimization, the protective cover 2 forms a relatively closed working space, effectively blocking the spread of welding fumes and metal debris into the working environment, and improving the working conditions of operators.

[0023] Example 7: Figures 1-15 As shown, the transport component 3 includes a transport platform 301, which slides on the support frame 401. The transport platform 301 is threadedly connected to the lead screw 403. Each of the four corners of the transport platform 301 is provided with a slanted groove 302. A moving rod 303 is slidably connected in the slanted groove 302. A locking nut 304 is threadedly connected to the lower end of the moving rod 303. The upper end of the locking nut 304 abuts against the transport platform 301. A right-angle bracket 305 is rotatably connected to the upper end of the moving rod 303. The working principle of the above technical solution is as follows: During operation, motor 402 starts, driving screw 403 to rotate. Through threaded connection, it drives the transport platform 301 to move precisely along the support frame 401, realizing the automatic conveying of the sheet material from the feeding position to the rolling position. Sliding moving rods 303 are installed in the inclined grooves 302 at the four corners of the transport platform 301. The upper end of the moving rod 303 is connected to a right-angle bracket 305, and the lower end is fixed by a locking nut 304. When it is necessary to accommodate sheets of different sizes, the locking nut 304 is loosened, and the moving rod 303 can slide obliquely within the inclined groove 302, adjusting the relative positions of the four right-angle brackets 305 to form a support frame that matches the sheet material size. The right-angle brackets 305 use a rotating... The dynamic connection design allows the contact surface to automatically adjust its angle according to the edge shape of the sheet material, ensuring tight contact with the four corners of the sheet material and providing stable support. After the locking nut 304 is tightened again, the moving rod 303 and the right-angle bracket 305 are fixed in position, forming a stable clamping structure. During the conveying process, the four right-angle brackets 305 apply a uniform constraint force to the sheet material, preventing it from shifting, shaking, or falling off during movement, and ensuring that the sheet material accurately reaches the rolling position. This adaptive clamping design allows the same set of equipment to handle sheet materials of various specifications without the need to change special clamps, greatly improving the versatility and production efficiency of the equipment, while ensuring the positioning accuracy of the sheet material, providing a good foundation for subsequent rolling processes.

[0024] Example 8: As Figures 1-15 As shown, the welding assembly includes a support box 7, which is fixed on the support frame 1. A slider 10 is slidably connected inside the support box 7. The slider 10 is threadedly connected to a lead screw 9. The end of the lead screw 9 is connected to the output end of a motor 8. The motor 8 is fixed on the support frame 1. The slider 10 is fixedly connected to a cylinder 11. The output end of the cylinder 11 is connected to a welding machine 12. The welding machine 12 is located above the inner mold core 601. The working principle of the above technical solution is as follows: Before the welding process begins, motor 8 starts, driving screw 9 to rotate, which in turn moves slider 10 precisely along support box 7, positioning the welding machine 12 at the starting position of the joint of the rolled plate. Subsequently, cylinder 11 starts, pushing the welding machine 12 downward, so that the welding torch is precisely aligned with the joint of the plate. During the welding process, motor 8 continuously controls screw 9 to rotate at a uniform speed, driving slider 10 and welding machine 12 to move smoothly along the axis of the rolled plate. At the same time, welding machine 12 automatically adjusts the welding parameters according to the thickness and material of the plate to ensure welding quality. After welding is completed, cylinder 11 retracts, lifting welding machine 12, and motor 8 rotates in the opposite direction, driving slider 10 and welding machine 12 back to the initial position to prepare for the next welding. This welding component works in conjunction with the rolling system, and welding is performed immediately after the plate is fully formed, avoiding intermediate transfer links, improving production efficiency, significantly reducing the need for manual intervention, and realizing fully automated high-quality welding production.
