TECHNICAL FIELD

[0001] The present application relates to the technical field of disc spring forming, in particular to a forming device for intelligent manufacturing of disc springs. BACKGROUND

[0002] In the stamping forming process of the disc spring, burr defects are easily generated at the edge of the inner ring. In order to ensure that the mechanical properties of the spring meet the standard and the assembly adaptability meets the technical standard, the inner ring of the disc spring needs to be polished and processed.

[0003] The patent with patent announcement number CN213615651U relates to a forming device for disc spring processing, which comprises a base and a dust extraction machine. The front and rear ends of the left and right sides of the base are provided with fixed columns, and the top of each fixed column is provided with an installation plate. The top center of the installation plate is provided with a gas cylinder, and the bottom of the gas cylinder is provided with an upper forming plate. The front of the dust extraction machine is provided with a dust extraction pipe, and the front end of the dust extraction pipe is connected with a dust extraction disc. The rear end of the dust extraction machine is connected with a dust outlet pipe, and the rear end of the dust outlet pipe is connected with a filter box. The double-opening maintenance door is provided on the left and right sides of the installation slot, which facilitates the maintenance of the driving motor in the later stage, and makes the equipment more convenient and efficient during use.

[0004] In the above-mentioned patent, the positioning polishing block is driven by the driving motor to rotate, so as to pre-treat and polish the inner ring of the disc spring sheet, thereby reducing the polishing process of the inner ring in the later stage. However, in actual polishing operation, only one disc spring is pre-polished each time, which increases the overall processing time, and the positioning and taking and placing operations of the single disc spring during processing need to be completed manually, which easily leads to low processing efficiency and affects the batch production progress. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a forming device for intelligent manufacturing of disc springs, which solves the problems raised in the above-mentioned background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a forming device for intelligent manufacturing disc springs, comprising a machine tool, a linear drive module fixedly mounted on the top of the machine tool, a servo motor fixedly mounted on the top of the moving end of the linear drive module, and a long grinding head fixedly mounted on the output end of the servo motor; further comprising: a base fixedly mounted on the top of the machine tool; a loading seat fixedly mounted on the top of the base, with lower semi-circular slots at both ends of the loading seat; a plurality of positioning pins fixedly mounted on the surface of the loading seat; and a plurality of... A set of tooling pallets, several of which are detachably mounted on the inner wall of the loading base, each tooling pallet having two positioning holes on its top and a workpiece positioning groove on its top for placing disc springs of uniform specifications. Disc springs to be ground are sequentially placed into the workpiece positioning grooves of the tooling pallets for pre-grinding. A bracket is fixedly mounted on the top of the base, and a rotating shaft is rotatably mounted on the bracket. A sliding groove is provided on the surface of the bracket. A cover plate is fixedly mounted on the circumferential surface of the rotating shaft, and an upper semi-circular groove matching the lower semi-circular groove is provided on the inner wall of the cover plate.

[0007] According to the above technical solution, a number of positioning pins are distributed in an equidistant array on the loading seat, and two positioning holes are symmetrically opened with the central axis of symmetry of the tooling tray as the reference. The circumferential surface of the positioning pin is in contact with the inner wall of the positioning hole, and the positioning hole of the tooling tray is precisely in contact with the positioning pin to complete the radial positioning of the tooling tray.

[0008] According to the above technical solution, a horizontal guide groove is provided on the side wall of the loading seat, a push rod is slidably installed in the horizontal guide groove, an L-shaped limiting block is fixedly installed on the circumferential surface of the push rod, and a rectangular protrusion is fixedly installed on the side wall of the cover plate. When the cover plate is flipped to the left, the cover plate drives the rectangular protrusion to move synchronously.

[0009] According to the above technical solution, the cover plate is provided with an elastic clamping device for clamping the tooling tray, and the bracket is provided with an auxiliary supporting device for supporting the cover plate; the elastic clamping device includes a hollow cylinder, a T-shaped rod, a first spring, a pressure plate and a rubber plate. The hollow cylinder is fixedly inserted through the surface of the cover plate. When the cover plate is flipped towards the loading seat, the cover plate synchronously drives the hollow cylinder to move. The T-shaped rod slides through the bottom of the inner wall of the hollow cylinder. The first spring is disposed between the hollow cylinder and the T-shaped rod. The pressure plate is fixedly installed at the bottom of the T-shaped rod, and the rubber plate is fixedly installed at the bottom of the pressure plate.

[0010] According to the above technical solution, a reinforcing rod is fixedly inserted through the circumference of the hollow cylinder, and both ends of the reinforcing rod are fixedly inserted through the surface of the cover plate. The reinforcing rod is used to improve the stability between the cover plate and the hollow cylinder. The cover plate provides reliable support for the reinforcing rod, and the reinforcing rod further improves the stability of the top of the hollow cylinder.

[0011] According to the above technical solution, a round rod is fixedly installed on the top of the pressure plate, and a round hole is opened on the cover plate near the round rod. The circumferential surface of the round rod fits against the inner wall of the round hole, and the round hole of the cover plate slides smoothly along the round rod, thereby enhancing the stability of the center position of the pressure plate.

[0012] According to the above technical solution, the auxiliary support device includes a sliding table, a cylindrical rod, a sleeve, a second spring, and a support pad. The sliding table is disposed on the surface of the bracket, and the bottom end of the sliding table fits into the sliding groove. The cylindrical rod is fixedly installed on the top of the sliding table. The sleeve is slidably installed on the circumferential surface of the cylindrical rod. The second spring is disposed between the cylindrical rod and the sleeve. The support pad is fixedly installed on the top of the sleeve. The top of the support pad has two arc-shaped grooves adapted to the reinforcing rod. The reinforcing rod first makes precise contact with the arc-shaped grooves of the support pad, and then applies downward pressure to the support pad.

[0013] According to the above technical solution, four support columns are fixedly installed on the top of the sliding table, and four connecting pipes are fixedly installed on the bottom of the supporting pad. The inner wall of the connecting pipe is in contact with the circumferential surface of the support column, and the support column forms a precise guiding constraint on the connecting pipe, so that the connecting pipe is always in contact with the circumferential surface of the support column during the displacement process.

[0014] This invention provides a forming apparatus for intelligent manufacturing disc springs. It has the following beneficial effects: (1) The intelligent manufacturing disc spring forming device lifts the tooling tray upwards to realize the convenient disassembly of the tooling tray. Through the quick disassembly and assembly design, it is not only convenient to uniformly recycle the tooling tray, but also to accurately position it with the help of positioning pins to ensure that the spacing of the tooling tray after placement is consistent, thereby ensuring the stability of the disc spring inner ring grinding operation. At the same time, the disc springs are placed into the workpiece positioning slots in sequence, and then the cover plate is flipped to limit and fix them. Through the design of multiple tooling trays, multiple disc springs can be clamped and ground at one time, which greatly shortens the auxiliary time of clamping and changing materials, thereby improving the processing efficiency of the disc spring inner ring grinding process.

[0015] (2) The forming device for processing disc springs in intelligent manufacturing applies downward pressure to the tooling tray to fix the tooling tray firmly on the loading seat. By enhancing the stability of the tooling tray during grinding, it not only avoids the grinding accuracy of the inner ring of the disc spring due to the shaking of the tooling tray, but also automatically releases the pressure on the tooling tray after the cover is opened. At the same time, the reinforcing rod can improve the stability of the top of the hollow cylinder. The reinforcing rod forms a reliable support for the top of the hollow cylinder and enhances the stability of the center of the pressure plate with the round rod, which can greatly improve the stability of pressing the tooling tray.

[0016] (3) The forming device for processing disc springs in intelligent manufacturing has an upward damping force formed by the second spring, which slows down the downward movement speed of the support pad. Through the damping buffer formed by the second spring, the impact force of the cover plate and the support pad can be effectively reduced, avoiding wear caused by rigid collision between the two, thereby reducing the cost of equipment maintenance and component replacement. At the same time, the connecting pipe is always in contact with the circumferential surface of the support column during the displacement process. Through the guiding and constraining effect of the support column on the connecting pipe, the overall stability of the support pad is significantly enhanced, ensuring that it will not shake during the process of supporting the reinforcing rod.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 - Figure 8 One embodiment of the present invention is: a forming device for intelligent manufacturing disc spring processing, comprising a machine tool 1, a linear drive module 2 fixedly mounted on the top of the machine tool 1, a servo motor 3 fixedly mounted on the top of the moving end of the linear drive module 2, and a long rod grinding head fixedly mounted on the output end of the servo motor 3; further comprising: a base 4 fixedly mounted on the top of the machine tool 1; a loading seat 5 fixedly mounted on the top of the base 4, with lower semi-circular slots opened at both ends of the loading seat 5; a plurality of positioning pins 6 fixedly mounted on the surface of the loading seat 5; a plurality of tooling trays 7; and a plurality of tooling supports 7. The mounting plate 7 is detachably mounted on the inner wall of the loading base 5. The top of the mounting plate 7 has two positioning holes and a workpiece positioning groove for placing disc springs of uniform specifications. The bracket 8 is fixedly mounted on the top of the base 4. A rotating shaft is rotatably mounted on the bracket 8, and a sliding groove is provided on the surface of the bracket 8. The cover plate 9 is fixedly mounted on the circumferential surface of the rotating shaft. The inner wall of the cover plate 9 has an upper semi-circular groove that matches the lower semi-circular groove. Through the design of multiple mounting plates 7, the clamping and grinding operations of multiple disc springs can be completed at one time, which greatly shortens the auxiliary time for clamping and changing materials.

[0021] Several positioning pins 6 are distributed in an equidistant array on the loading seat 5. Two positioning holes are symmetrically opened with the central axis of symmetry of the tooling tray 7 as the reference. The circumferential surface of the positioning pin 6 fits against the inner wall of the positioning hole. Through the quick disassembly and assembly design, it is convenient to uniformly recycle the tooling tray 7 and can accurately position it with the help of the positioning pin 6 to ensure that the spacing of the tooling tray 7 after placement remains consistent.

[0022] A horizontal guide groove is provided on the side wall of the loading seat 5. A push rod 10 is slidably installed in the horizontal guide groove. An L-shaped limiting block 11 is fixedly installed on the circumferential surface of the push rod 10. A rectangular protrusion 12 is fixedly installed on the side wall of the cover plate 9. After the L-shaped limiting block 11 is displaced, it applies a limiting fixation to the rectangular protrusion 12 to ensure the stability of the cover plate 9 during the grinding process.

[0023] In this embodiment, the disc springs to be ground are placed into the workpiece positioning slots of the tooling tray 7 in sequence. Then, the cover plate 9 is flipped to the left. The cover plate 9 drives the rectangular protrusion 12 to move synchronously. During the flipping process, the cover plate 9 is in contact with the top of the loading seat 5. At the same time, the upper semi-circular groove of the cover plate 9 is precisely in contact with the circumferential surface of the disc spring, thereby stably limiting the disc spring in the workpiece positioning slot. Then, the push rod 10 is pushed to the right. The push rod 10 drives the L-shaped limiting block 11 to move synchronously until the L-shaped limiting block 11 is in contact with the top of the rectangular protrusion 12, thus limiting and fixing the rectangular protrusion 12 and ensuring that the cover plate 9 always maintains a tight contact with the loading seat 5 during the grinding operation. After the limit operation is completed, the linear drive module 2 and servo motor 3 are started synchronously. The moving end of the linear drive module 2 drives the servo motor 3 to move to the right at a constant speed. The output end of the servo motor 3 drives the long rod grinding head to rotate at high speed. During this process, the long rod grinding head passes through the upper semicircular groove and the lower semicircular groove, and contacts the inner ring of the disc spring in the limit state in turn, completing the inner ring pretreatment grinding operation. After the grinding operation is completed, the motion end of the linear drive module 2 drives the servo motor 3 to reset, push the push rod 10 to the left to release the limiting constraint of the L-shaped limit block 11 on the rectangular protrusion 12, and finally open the cover plate 9 to take out the ground disc springs in sequence. Through the design of multiple tooling trays 7, the clamping and grinding operations of multiple disc springs can be completed at one time, which greatly shortens the auxiliary time of clamping and changing materials, thereby improving the processing efficiency of the inner ring grinding process of disc springs. After the pre-treatment grinding is completed, the tooling tray 7 can be lifted upwards. During the upward movement of the tooling tray 7, the positioning holes on both sides quickly disengage from the positioning pins 6, enabling convenient disassembly of the tooling tray 7. After disassembly, the tooling tray 7 can be stored uniformly. When grinding is carried out again, if the thickness of the disc spring to be ground changes, a tooling tray 7 with the new specifications can be customized. The new tooling tray 7 is then smoothly lowered from directly above the loading seat 5. During the lowering process, the positioning holes of the tooling tray 7 first precisely engage with the positioning pins 6 to complete the radial positioning of the tooling tray 7. Subsequently, the tooling tray 7 fits against the inner wall of the loading seat 5, completing the rapid placement of the tooling tray 7. Through the quick disassembly and assembly design, it is not only convenient to uniformly collect the tooling tray 7, but also to accurately position it with the help of the positioning pins 6, ensuring that the spacing of the tooling tray 7 remains consistent after placement, thereby ensuring the stability of the disc spring inner ring grinding operation.

[0024] Please see Figure 1 - Figure 8Based on the above embodiments, in another embodiment of the present invention, the cover plate 9 is provided with an elastic clamping device for clamping the tooling tray 7, and the bracket 8 is provided with an auxiliary supporting device for supporting the cover plate 9; the elastic clamping device includes a hollow cylinder 21, a T-shaped rod 22, a first spring 23, a pressure plate 24, and a rubber plate 25. The hollow cylinder 21 is fixedly inserted through the surface of the cover plate 9, the T-shaped rod 22 slides through the bottom of the inner wall of the hollow cylinder 21, the first spring 23 is disposed between the hollow cylinder 21 and the T-shaped rod 22, the pressure plate 24 is fixedly installed at the bottom of the T-shaped rod 22, and the rubber plate 25 is fixedly installed at the bottom of the pressure plate 24. By enhancing the stability of the tooling tray 7 during grinding, the grinding accuracy of the inner ring of the disc spring can be avoided due to the shaking of the tooling tray 7.

[0025] A reinforcing rod 26 is fixedly inserted through the circumference of the hollow cylinder 21. Both ends of the reinforcing rod 26 are fixedly inserted through the surface of the cover plate 9. The reinforcing rod 26 is used to improve the stability between the cover plate 9 and the hollow cylinder 21. The reinforcing rod 26 forms a reliable support for the top of the hollow cylinder 21, thereby improving the stability of the clamping tooling tray 7.

[0026] A round rod 27 is fixedly installed on the top of the pressure plate 24. A round hole is opened on the cover plate 9 near the round rod 27. The circumferential surface of the round rod 27 fits against the inner wall of the round hole. The round rod 27 enhances the stability of the center of the pressure plate 24, ensuring that each tooling tray 7 can be stably fixed in the preset position.

[0027] The auxiliary support device includes a sliding table 31, a cylindrical rod 32, a sleeve 33, a second spring 34, and a support pad 35. The sliding table 31 is set on the surface of the bracket 8, and the bottom end of the sliding table 31 fits into the sliding groove. The cylindrical rod 32 is fixedly installed on the top of the sliding table 31. The sleeve 33 is slidably installed on the circumferential surface of the cylindrical rod 32. The second spring 34 is set between the cylindrical rod 32 and the sleeve 33. The support pad 35 is fixedly installed on the top of the sleeve 33. The top of the support pad 35 has two arc-shaped grooves that are adapted to the reinforcing rod 26. Through the damping buffer formed by the second spring 34, the impact force of the cover plate 9 contacting the support pad 35 can be effectively reduced, and wear caused by rigid collision between the two can be avoided.

[0028] Four support columns 36 are fixedly installed on the top of the sliding table 31, and four connecting pipes 37 are fixedly installed on the bottom of the support plate 35. The inner wall of the connecting pipe 37 fits against the circumferential surface of the support column 36. Through the guiding and constraining effect of the support column 36 on the connecting pipe 37, the overall stability of the support plate 35 is significantly enhanced, ensuring that it will not shake during the process of supporting the reinforcing rod 26.

[0029] In this embodiment, when the cover plate 9 is flipped towards the loading seat 5, the cover plate 9 simultaneously drives the hollow cylinder 21 to move. The hollow cylinder 21 further drives the T-shaped rod 22 and the reinforcing rod 26 to move simultaneously. The T-shaped rod 22 then drives the pressure plate 24 and the rubber plate 25 to move closer to the tooling tray 7. During this process, the rubber plate 25 first contacts the top of the tooling tray 7. As the cover plate 9 continues to flip, the hollow cylinder 21 gradually squeezes the first spring 23. The squeezed first spring 23 undergoes elastic deformation and applies elastic thrust to the T-shaped rod 22 during deformation. This thrust is transmitted to the top of the tooling tray 7 through the pressure plate 24 and the rubber plate 25, forming a downward pressure on the tooling tray 7, which firmly fixes the tooling tray 7 on the loading seat 5. By enhancing the stability of the tooling tray 7 during grinding, it not only avoids the grinding accuracy of the inner ring of the disc spring being affected by the shaking of the tooling tray 7, but also automatically releases the pressure on the tooling tray 7 after the cover plate 9 is opened. When the hollow cylinder 21 moves synchronously with the cover plate 9, the cover plate 9 provides reliable support for the reinforcing rod 26, which in turn improves the stability of the top of the hollow cylinder 21 and enhances the overall anti-shaking ability of the hollow cylinder 21. When the rubber plate 25 contacts the top of the tooling support plate 7, the rubber plate 25 stops moving due to the support of the tooling support plate 7. At this time, the cover plate 9, which continues to flip, slides smoothly along the round rod 27 through its round hole, thereby enhancing the stability of the center position of the pressure plate 24 and preventing the pressure plate 24 from tilting. The reinforcing rod 26 provides reliable support for the top of the hollow cylinder 21, and the round rod 27 enhances the stability of the center of the pressure plate 24, which can greatly improve the stability of pressing the tooling support plate 7. After the pre-grinding operation is completed, the cover plate 9 is flipped to the right, so that the hollow cylinder 21 moves synchronously and drives the reinforcing rod 26 to move together. During this process, the reinforcing rod 26 first makes precise contact with the arc-shaped groove of the support plate 35, and then applies downward pressure to the support plate 35. This pressure pushes the support plate 35 to move vertically downward. The support plate 35 drives the sleeve 33 to move downward at the same time. During the downward movement, the sleeve 33 squeezes the second spring 34. The squeezed second spring 34 undergoes elastic deformation and generates an upward damping force in the deformation. This damping force can effectively slow down the downward movement speed of the support plate 35 until the support plate 35 reaches a stable state. Through the damping buffer formed by the second spring 34, the impact force of the cover plate 9 contacting the support plate 35 can be effectively reduced, avoiding wear caused by rigid collision between the two, thereby reducing the cost of equipment maintenance and component replacement. When the support plate 35 moves downward, the connecting pipe 37, which is fixedly connected to it, moves downward together. During this process, the connecting pipe 37 slides smoothly along the circumferential surface of the support column 36. The support column 36 forms a precise guiding constraint on the connecting pipe 37, so that the connecting pipe 37 always fits against the circumferential surface of the support column 36 during the displacement. This constraint can effectively ensure the displacement stability of the four corners of the support plate 35 and prevent the support plate 35 from tilting or shifting during the downward movement. Through the guiding constraint of the supporting column 36 on the connecting pipe 37, the overall stability of the support plate 35 is significantly enhanced, ensuring that it will not shake during the support of the reinforcing rod 26.
