Description

Technical Field

[0001] This invention relates to the field of valve plate stamping technology, specifically to a shock absorber valve plate stamping device. Background Technology

[0002] Stamping equipment is an indispensable core process equipment in the field of machinery manufacturing. It uses a press and dies to apply external force to blanks such as sheet metal and strip, causing them to separate and thus obtain workpieces of the required shape and size. As an important basic equipment in the modern industrial production system, stamping equipment is widely used in many fields such as automobile manufacturing.

[0003] In existing technologies, when stamping irregularly shaped valve plates (such as hexagonal valve plates), the stamping device continuously stamps the stamping strip by reciprocating vertically downwards using a stamping head, thereby forming the irregularly shaped valve plate. However, during the stamping process, the stamping head of this type of device can only achieve linear up-and-down movement and cannot be rotated along the vertical axis. This limitation of movement results in a large distance between two adjacent stamping positions on the stamping strip, leaving a large unused area on the strip (such as...). Figure 21 (As shown). As a result, the stamped strip material cannot be fully used for processing irregularly shaped valve plates, resulting in material waste and reduced utilization.

[0004] Therefore, a shock absorber valve plate stamping device is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a shock absorber valve plate stamping device to solve the problem that the stamping material cannot be fully utilized when stamping irregularly shaped valve plates, resulting in material waste and reduced utilization rate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shock absorber valve plate stamping device includes a stamping body, a processing table and a stamping box installed in the middle of the stamping body; a lifting component is installed vertically inside the stamping body, a stamping component is fixed on the top of the lifting component, a rotary stamping structure is rotatably installed inside the stamping box, and the stamping end of the stamping component is rotatably connected relative to the rotary stamping structure; a rotary stamping table corresponding vertically to the rotary stamping structure is installed inside the processing table.

[0008] Two sets of clutch-type drive structures are installed in the middle of the stamping body. The lifting component can move up and down relative to the clutch-type drive structures. The two clutch-type drive structures are connected to the side of the lifting component through a telescopic structure. The clutch part of the clutch-type drive structure can extend and retract relative to the lifting component through the telescopic structure, so as to realize the separable setting of the lifting component and the clutch-type drive structure. When the lifting component moves up and down, the lifting component drives the telescopic structure to adjust the extension and retraction of the clutch-type drive structure. The front ends of the two sets of clutch-type drive structures are respectively connected to the rotary stamping structure and the rotary stamping table.

[0009] When the lifting component moves upward, it drives the two clutch-type drive structures to rotate synchronously, so that the two clutch-type drive structures drive the rotary stamping structure and the rotary stamping table to rotate synchronously and adjust. When the lifting component moves downward, the stamping component drives the rotary stamping structure, after rotation adjustment, to move downward relative to the rotary stamping table in order to stamp the stamping strip placed on the processing table.

[0010] Furthermore: the stamping part includes a column fixed to the top of the lifting part, a crossbeam fixed to the top of the column, a stamping rod fixed to the end of the crossbeam away from the column, and the bottom end of the stamping rod extends through the stamping body into the interior of the stamping box.

[0011] Furthermore: the rotary stamping structure includes a rotary drum rotatably installed inside the stamping box, a lifting column is installed inside the rotary drum that moves up and down, a stamping connector that is rotatably connected to the stamping rod is fixed at the top of the lifting column, and a stamping head is fixed at the bottom of the lifting column.

[0012] Furthermore: a drive ring is fixed to the inner circumferential wall of the rotating cylinder, and a number of drive holes are equally spaced along the circumferential direction on the drive ring. A drive rod is slidably installed in each drive hole, and the two ends of the drive rod are fixedly connected to the stamping connector and the stamping head, respectively.

[0013] Furthermore: the rotary stamping table includes a stamping base rotatably installed in the processing table, and a stamping groove corresponding to the stamping head is opened in the center of the stamping base. The bottom end of the stamping base is connected to a rotating seat rotatably installed in the middle of the stamping body. The rotating seat is used to drive the stamping base to rotate and adjust.

[0014] Furthermore: the clutch-type drive structure includes a rotating shaft rotatably mounted in the middle of the stamping body, a telescopic cylinder is mounted on one end of the rotating shaft, a drive gear is fixed on one end of the telescopic cylinder, and a main bevel gear is fixed on the other end of the rotating shaft, the main bevel gear and the auxiliary bevel gear are meshed.

[0015] The secondary bevel gear of the clutch-type drive structure corresponding to the rotary stamping structure is fixedly connected to the rotary drum; the secondary bevel gear of the clutch-type drive structure corresponding to the rotary stamping table is fixedly connected to the rotating base.

[0016] Furthermore: the middle part of the lifting component has an elongated hole along its length, and two sets of racks that cooperate with the drive gear are fixed to the inner sidewall of the elongated hole; when the lifting component moves the racks downward, the racks and the drive gear are staggered; when the lifting component moves the racks upward, the racks and the drive gear are engaged.

[0017] Furthermore: the telescopic structure includes a "U"-shaped component rotatably mounted on two telescopic cylinders, with sliding components installed on both sides of the "U"-shaped component, and guide grooves that cooperate with the sliding components are respectively opened on both sides of the lifting component.

[0018] Furthermore: the sliding component includes a fixed cylinder fixed to the side of the "U"-shaped component, a telescopic shaft is slidably installed inside the fixed cylinder along the axial direction, and an elastic support element that cooperates with the telescopic shaft is also installed inside the fixed cylinder.

[0019] Furthermore: the guide groove includes a downward guide groove and an upward guide groove, and the downward guide groove and the upward guide groove are connected end to end to form an "isosceles trapezoid" structure; the depth of the downward guide groove increases from top to bottom, and the depth of the upward guide groove decreases from top to bottom; the depth of the top of the upward guide groove is greater than the depth of the top of the downward guide groove, and the depth of the bottom of the upward guide groove is less than the depth of the bottom of the downward guide groove.

[0020] The beneficial effects of this invention are:

[0021] When the stamping device of this invention is reset, the lifting component drives the rotary stamping structure and the rotary stamping table to rotate synchronously through two sets of clutch-type drive structures, thus adjusting for the next stamping. When the stamping device continuously stamps the stamping strip, the two clutch-type drive structures drive the rotary stamping structure and the rotary stamping table to rotate synchronously, thereby changing the stamping angle of the rotary stamping structure on the stamping strip. Since the stamping angle is adjustable, the stamping strip only needs to move a short distance before the next stamping to meet the material requirements of the irregular valve plate, significantly reducing the distance between two adjacent stamping positions. Therefore, more irregular valve plates can be processed on the same length of stamping strip, effectively improving material utilization and reducing waste of stamping strip.

[0022] During the upward movement of the stamping device of this invention, the cooperation of the guide groove and the telescopic structure enables the clutch-type drive structure to engage with the rack on the lifting component; during the downward movement of the stamping device, the cooperation of the guide groove and the telescopic structure enables the clutch-type drive structure to disengage from the rack on the lifting component, thereby allowing for flexible changes according to the lifting component's movement. During the stamping process with the stamping strip, contact between the lifting component and the clutch-type drive structure can be avoided, reducing the impact on the stamping process and thus improving the pass rate of the shock absorber valve plate stamping.

[0046] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0047] like Figure 1 and 2As shown, a shock absorber valve plate stamping device includes a stamping body 1. A processing table 2 and a stamping box 3 are respectively installed in the middle part of the stamping body 1, and the stamping box 3 is located directly above the processing table 2. The lower part of the stamping body 1 is provided with an inwardly recessed collection groove 12, and the collection groove 12 is located directly below the processing table 2. Under normal circumstances, a collection box 13 with an open top is placed inside the collection groove 12. Through the setting of the collection box 13, the stamped irregular valve plates can fall directly into the collection box 13, realizing the automatic collection of finished products, effectively reducing the burden of manual collection, and improving the convenience of operation.

[0048] like Figure 12 As shown; a hydraulic cylinder 14 is installed at the bottom inside the stamping body 1. The driving end of the hydraulic cylinder 14 is fixedly connected to the bottom end of the lifting component 4. The hydraulic cylinder 14 can provide driving force to the lifting component 4 to ensure that the stamping device can operate normally. A stamping component 5 is fixed at the top of the lifting component 4, and the stamping end of the stamping component 5 extends to the outside of the stamping body 1 and is rotatably connected to the rotary stamping structure 6 installed in the stamping box 3. When the lifting component 4 drives the stamping component 5 to move downward, the stamping component 5 can drive the rotary stamping structure 6 to move downward and stamp the stamping strip 10 placed on the processing table 2 to complete the stamping of the irregular valve plate.

[0049] like Figure 2 As shown, a slide rail 15 is fixed vertically on the inner wall of the stamping body 1, and a guide rod 16 is fixed on the side of the lifting component 4 away from the stamping box 3. The guide rod 16 is slidably mounted on the slide rail 15. Through the cooperation of the slide rail 15 and the guide rod 16, the lifting component 4 is limited, so that the movement trajectory of the lifting component 4 can only move up and down, preventing deviation and improving the stability of the device.

[0050] like Figure 2 As shown, a rotary stamping table 7 is installed in the center of the processing table 2. It should be noted that the rotary stamping table 7 and the rotary stamping structure 6 are arranged vertically to ensure that the irregular valve pieces are stamped normally. The bottom end of the rotary stamping table 7 is connected to the collection groove 12. The advantage of this design is that the stamped irregular valve pieces can fall directly into the collection box 13, reducing the collection work and providing convenience for the staff.

[0051] like Figure 11As shown in Figure 12; two sets of clutch-type drive structures 8 are installed in the middle of the stamping body 1, and the two sets of clutch-type drive structures 8 are arranged vertically. The rear ends of the two sets of clutch-type drive structures 8 are detachably connected to the same lifting member 4; the front end of the upper clutch-type drive structure 8 is connected to the rotary stamping structure 6; the front end of the lower clutch-type drive structure 8 is connected to the rotary stamping table 7; it should be noted that the two sets of clutch-type drive structures 8 are equipped with the same telescopic structure 9, and the two sides of the telescopic structure 9 are connected to the sides of the lifting member 4; when the lifting member 4 moves upward, the two clutches are driven by the telescopic structure 9 respectively. The clutch drive structure 8 extends to connect the clutch part of the clutch drive structure 8 with the lifting member 4, and drives the two sets of clutch drive structures 8 to operate normally. The two sets of clutch drive structures 8 can provide driving force to the rotary stamping structure 6 and the rotary stamping table 7 respectively, so that the rotary stamping structure 6 and the rotary stamping table 7 can rotate and adjust synchronously. When the lifting member 4 moves downward, the telescopic structure 9 can drive the clutch parts of the two sets of clutch drive structures 8 to retract, so that the clutch drive structure 8 is disengaged from the lifting member 4, preventing the clutch drive structure 8 from affecting the downward movement of the lifting member 4 during the stamping of the irregular valve plate.

[0052] like Figure 3 As shown in Figure 4; the processing table 2 includes a processing table body 201, and side plates 202 are fixed on both sides of the top of the processing table body 201 along the length direction, and the two side plates 202 are arranged parallel to each other. A cavity 203 is opened inside the processing table body 201, and two sets of conveying structures 204 are installed inside the cavity 203. The two sets of conveying structures 204 are located on both sides of the rotary stamping table 7. Through the arrangement of the two sets of conveying structures 204, the stamping strip 10 placed on the processing table body 201 can be conveyed in a progressive manner to ensure that the stamping strip 10 is stamped at different positions.

[0053] like Figure 6As shown; the conveying structure 204 includes a rotating rod 2041 rotatably mounted in the cavity 203 along the width direction of the processing table body 201. Preferably, there are two rotating rods 2041, which are parallel to each other and located on the same horizontal plane. A motor 2042 is installed inside the cavity 203. The motor 2042 can be a servo motor or a stepper motor; this improves the rotation accuracy and ensures that the rotation is performed at a specified angle each time. A second transmission gear 2046 is fixed to the output end of the motor 2042 and one of the rotating rods 2041, and the two second transmission gears 2046 are... The rotating rods 2041 are intermeshing; the motor 2042 and the second transmission gear 2046 work together to provide driving force to the rotating rods 2041; the two rotating rods 2041 are respectively fixed with first transmission gears 2043, and the two first transmission gears 2043 are connected by a chain 2044. The cooperation of the first transmission gears 2043 and the chain 2044 ensures that the two rotating rods 2041 rotate synchronously. The two ends of each rotating rod 2041 extend to the outside of the processing table body 201 and are equipped with conveying components 2045. The two sets of corresponding conveying components 2045 are used to convey the stamping strip 10.

[0054] like Figure 5 As shown; a plurality of receiving grooves 2021 are equally spaced on the inner side wall of the side plate 202, and a plurality of conveying components 2045 are respectively located inside the receiving grooves 2021. A horizontal conveying groove 2022 is also provided on the inner side wall of the side plate 202, and the conveying groove 2022 is connected to the plurality of receiving grooves 2021. When the two sides of the stamping strip 10 pass through the conveying groove 2022, the two sides of the stamping strip 10 are squeezed between the plurality of conveying components 2045.

[0055] like Figure 5 and 6 As shown; the conveying assembly 2045 includes a main conveying wheel 20451 and a secondary conveying wheel 20452 located in the receiving groove 2021. The shaft of the main conveying wheel 20451 is fixedly connected to the end of the rotating rod 2041. A rotating shaft 20453 is fixed at the shaft of the secondary conveying wheel 20452. A rotating hole 2023 is opened above the conveying groove 2022. The rotating shaft 20453 is rotatably installed inside the rotating hole 2023.

[0056] like Figure 6As shown; under normal circumstances: gears 20454 are fixed on the side of the main conveyor wheel 20451 and the auxiliary conveyor wheel 20452 near the receiving groove 2021, and the two gears 20454 are meshed. When the main conveyor wheel 20451 rotates, the auxiliary conveyor wheel 20452 can be driven to rotate through the cooperation of the two gears 20454, so that the main conveyor wheel 20451 and the auxiliary conveyor wheel 20452 rotate in a relative manner and convey the stamping strip 10.

[0057] like Figure 4 As shown, a mounting hole 2047 is provided in the middle of the processing table body 201. The mounting hole 2047 is located between the two conveying structures 204 and is used to mount the rotary stamping table 7. An annular groove 2048 is provided at the top of the mounting hole 2047 to place the stamping base 701 of the rotary stamping table 7, preventing the stamping base 701 from falling downwards due to its own weight, so that the stamping base 701 and the top surface of the rotating seat 703 always maintain a certain gap. The purpose of this design is to avoid the vibration force generated by the collision between the rotary stamping structure 6 and the rotary stamping table 7 during the stamping process from affecting the clutch-type drive structure 8 located below.

[0058] like Figure 12 As shown in Figure 13; the stamping part 5 includes a column 501 fixed at the center of the top of the lifting part 4, a horizontally arranged crossbeam 502 fixed at the top of the column 501, a stamping rod 503 fixed at the end of the crossbeam 502 away from the column 501, and the bottom end of the stamping rod 503 extends through the stamping body 1 into the interior of the stamping box 3, which can ensure that downward stamping force is provided to the rotary stamping structure 6.

[0059] like Figure 7-9 As shown; the rotary stamping structure 6 includes a rotating cylinder 601 rotatably installed inside the stamping box 3. It should be noted that: annular grooves 301 are respectively provided on the upper and lower parts of the inner circumferential wall of the stamping box 3, and a first bearing 608 fixed to the rotating cylinder 601 is installed inside the annular groove 301. The first bearing 608 ensures that the rotating cylinder 601 can rotate smoothly within the stamping box 3 without easily jamming; a storage groove 302 is provided in the middle part of the stamping box 3, and the shape of the storage groove 302 is based on... The main bevel gear 804 and the secondary bevel gear 805 are set according to their meshing shape, so that the main bevel gear 804 and the secondary bevel gear 805 can be stored. The inside of the rotating drum 601 is equipped with a lifting column 602 that moves up and down. The top of the lifting column 602 is fixed with a stamping connector 603. The stamping connector 603 is rotatably connected to the stamping rod 503. The bottom of the lifting column 602 is fixed with a stamping head 604. The stamping head 604 is used to stamp the stamping strip 10.

[0060] like Figure 10 and11 As shown; a drive ring 605 is fixed to the inner circumferential wall of the rotating drum 601. Several drive holes 606 are equally spaced along the circumferential direction on the drive ring 605. A drive rod 607 is slidably installed in each drive hole 606. The two ends of the drive rod 607 are fixedly connected to the stamping connector 603 and the stamping head 604, respectively. During the rotation of the rotating drum 601, the stamping head 604 can be rotated and adjusted by the cooperation of the drive ring 605 and the drive rod 607.

[0061] It should be noted that the distance the lifting component 4 moves from the top to the bottom is less than the length of the lifting column 602. This ensures that the stamping connector 603 will not collide with the drive ring 605 when it moves downward or the stamping head 604 moves upward, thus avoiding the impact of the vibration force generated by the collision on the clutch-type drive structure 8 located at the top.

[0062] like Figure 11 As shown, a rotating groove 6031 is provided at the center of the top of the stamped connector 603, and the bottom end of the stamping rod 503 is inserted into the rotating groove 6031. An annular limiting groove 6032 is provided on the inner circumferential wall of the rotating groove 6031. An annular protrusion 504 is fixed at the bottom end of the stamping rod 503, and the annular protrusion 504 is rotatably installed inside the annular limiting groove 6032. Through the cooperation of the annular limiting groove 6032 and the annular protrusion 504, a limiting function is achieved to prevent the stamped connector 603 from detaching from the bottom end of the stamping rod 503.

[0063] like Figure 18 As shown; the rotary stamping table 7 includes a stamping base 701 rotatably installed in the mounting hole 2047. A stamping groove 702 is provided in the center of the stamping base 701, and the stamping groove 702 is correspondingly arranged with the stamping head 604. The lower part of the stamping base 701 is connected to a rotating seat 703 rotatably installed in the center of the stamping body 1. Under normal circumstances, a second bearing 704 is fixed at the connection between the rotating seat 703 and the stamping body 1. The setting of the second bearing 704 allows the rotating seat 703 to rotate more smoothly on the stamping body 1 without jamming. A drop groove 705 is provided in the center of the second bearing 704, and the drop groove 705 is correspondingly arranged with the stamping groove 702. The setting of the drop groove 705 allows the stamped irregular valve plate to fall directly into the collection box 13 through the drop groove 705, thereby playing a collection role.

[0064] like Figure 18As shown; in detail: the top of the stamping base 701 is fixed with an annular protrusion 708, and the annular protrusion 708 is placed inside the annular groove 2048. Through the cooperation of the annular protrusion 708 and the annular groove 2048, the stamping base 701 is placed to prevent it from falling downwards due to its own weight. This ensures that the stamping base 701 and the rotating seat 703 always maintain a certain gap, which is used to release the vibration force generated during stamping. This reduces the direct transmission of the vibration force generated during stamping to the rotating seat 703, so as not to affect the clutch-type drive structure 8 located below.

[0065] like Figure 18 As shown; in detail: the bottom end of the stamping base 701 is fixed with several insert shafts 706 at equal intervals along the circumferential direction, and the top of the rotating seat 703 is provided with several insert holes 707 at equal intervals along the circumferential direction, and the insert shafts 706 are respectively inserted into the insert holes 707, and the depth of the insert hole 707 is greater than the length of the insert shaft 706, reducing the contact area between the insert hole 707 and the insert shaft 706; during the rotation of the rotating seat 703, the stamping base 701 can be driven to rotate through the cooperation of the insert holes 707 and the insert shafts 706.

[0066] It should be noted that: the upper clutch drive structure 8 is directly installed in the middle of the stamping body 1; the lower clutch drive structure 8 is rotatably installed in the middle of the stamping body 1 via a rotating support (not shown in the figure), and the rotating support is fixed to the top of the collecting groove 12; the structure, size and working principle of the two clutch drive structures 8 are completely compatible. For ease of description, this application only provides a detailed description of one of the clutch drive structures 8.

[0067] like Figure 14 and 15 As shown; the clutch-type drive structure 8 includes a rotating shaft 801 (the rotating shaft 801 of the upper clutch-type drive structure 8 is fixed to the side of the stamping body 1 by a third bearing 808; the rotating shaft 801 of the lower clutch-type drive structure 8 is fixed to the rotating support by a third bearing 808; the setting of the third bearing 808 allows the rotating shaft 801 to rotate more smoothly on the stamping body 1), a telescopic cylinder 802 is installed at the end of the rotating shaft 801 near the lifting member 4, and a drive gear 803 is fixed at one end of the telescopic cylinder 802; a main bevel gear 804 is fixed at the end of the rotating shaft 801 away from the lifting member 4, and the main bevel gear 804 meshes with a secondary bevel gear 805 (the secondary bevel gear 805 of the upper clutch-type drive structure 8 is fixed on the outer circumferential surface of the rotating cylinder 601, and the secondary bevel gear 805 of the lower clutch-type drive structure 8 is fixed on the outer circumferential surface of the rotating seat 703).

[0068] like Figure 15As shown; it should be noted that: several guide grooves 806 are equidistantly provided on the circumferential surface of the rotating shaft 801, and several guide rods 807 are equidistantly fixed on the inner circumferential wall of the telescopic cylinder 802 along the axial direction. The several guide rods 807 are slidably installed inside the guide grooves 806 respectively. Through the cooperation of the guide grooves 806 and the guide rods 807, they play a limiting role and prevent the rotating shaft 801 and the telescopic cylinder 802 from rotating in a relative manner.

[0069] like Figure 16 , 19 Or as shown in Figure 20; the middle part of the lifting component 4 has an elongated hole 401 along its length. The inner wall of the elongated hole 401 is provided with two sets of racks 402, and the two sets of racks 402 respectively cooperate with the drive gear 803. It should be noted that when the lifting component 4 moves downward, through the cooperation of the telescopic structure 9 and the guide slide 11, the drive gear 803 on the clutch drive structure 8 can be driven to move backward (that is, the drive gear 803 moves away from the stamping box 3), so that the drive gear 803 and the rack 402 are staggered (refer to...). Figure 19 To prevent the drive gear 803 from affecting the downward movement of the lifting component 4 during the downward pressing process; when the lifting component 4 moves upward, the drive gear 803 on the clutch-type drive structure 8 can be driven forward by the cooperation of the telescopic structure 9 and the guide slide 11 (that is, the drive gear 803 moves towards the stamping box 3), so that the drive gear 803 and the rack 402 are located on the same vertical line and meshed (see reference). Figure 20 Through the cooperation of two clutch-type drive structures 8, the rotary stamping structure 6 and the rotary stamping table 7 can be driven to rotate synchronously. During the next stamping of the stamping strip 10, the stamping angle of the rotary stamping structure 6 on the stamping strip 10 is changed. Since the stamping angle is adjustable, the stamping strip 10 only needs to move a short distance before the next stamping to meet the stamping requirements, significantly reducing the distance between adjacent stamping positions. Therefore, more irregularly shaped valve plates can be processed on the same length of stamping strip 10, effectively improving material utilization and reducing waste of the stamping strip 10.

[0070] like Figure 14As shown; the telescopic structure 9 includes a "U"-shaped component 901 rotatably mounted on two telescopic cylinders 802, and a fourth bearing 903 is provided at the connection between the telescopic cylinder 802 and the "U"-shaped component 901. The fourth bearing 903 enables the telescopic cylinder 802 to rotate smoothly on the "U"-shaped component 901, and it is not easy to jam during use. Sliding components 902 are respectively installed on both sides of the "U"-shaped component 901. The sliding components 902 enable the "U"-shaped component 901 to move according to the motion trajectory set by the guide groove 11.

[0071] like Figure 17 As shown; specifically: the sliding component 902 includes a fixed cylinder 9021 fixed to the side of the "U"-shaped component 901. A telescopic shaft 9022 is slidably installed inside the fixed cylinder 9021. One end of the telescopic shaft 9022 passes through the fixed cylinder 9021 and extends into the guide groove 11. The end of the telescopic shaft 9022 extending into the guide groove 11 is hemispherical. The advantage of this arrangement is that it can reduce the contact area between the telescopic shaft 9022 and the guide groove 11, reduce friction, and improve smoothness. An elastic support element 9023 is also fixed inside the fixed cylinder 9021. The elastic support element 9023 is a compression spring, and one end of the elastic support element 9023 is fixedly connected to one end of the telescopic shaft 9022. The elastic support element 9023 provides elastic support for the telescopic shaft 9022, allowing the sliding component 902 to be flexibly adjusted according to the depth of the guide groove 11, thereby improving the performance of the device.

[0072] like Figure 13 As shown in Figure 14; it should be noted that: two horizontal positioning rods 17 are also fixed on the inner wall of the stamping body 1, and the two positioning rods 17 are set close to the stamping box 3, and positioning seats 18 are slidably installed on the two positioning rods 17 respectively. The two positioning seats 18 are fixed on both sides of the "U" shaped part 901 respectively. Through the cooperation of the positioning rods 17 and the positioning seats 18, the "U" shaped part 901 is positioned to prevent the "U" shaped part 901 from shifting up and down or left and right, and has strong stability.

[0073] like Figure 16As shown; guide grooves 11 are respectively provided on both sides of the lifting component 4, and the guide grooves 11 include a downward guide groove 1101 and an upward guide groove 1102. The downward guide groove 1101 and the upward guide groove 1102 are connected end to end to form an "isosceles trapezoid" structure. It should be noted that: when the lifting component 4 moves downward, the sliding component 902 slides inside the downward guide groove 1101; when the lifting component 4 moves upward, the sliding component 902 slides inside the upward guide groove 1102. It should be noted that: the downward guide groove 1101 is set in a "vertical" shape, and the depth of the downward guide groove 1101 gradually increases from top to bottom, and the depth of the upward guide groove... The depth of 1102 gradually decreases from top to bottom; the depth of the top of the upward guide groove 1102 is greater than the depth of the top of the downward guide groove 1101, and the depth of the bottom of the upward guide groove 1102 is less than the depth of the bottom of the downward guide groove 1101. The advantage of this design is that when the lifting member 4 moves downward to the bottom, the sliding member 902 on the telescopic structure 9 can switch from the downward guide groove 1101 to the inside of the upward guide groove 1102; when the lifting member 4 moves upward to the top, the sliding member 902 on the telescopic structure 9 can switch from the upward guide groove 1102 to the inside of the downward guide groove 1101, thereby realizing the function of switching back and forth.

[0074] Working principle:

[0075] When the stamping device stamps the irregularly shaped valve plate of the shock absorber, the following steps are performed to stamp the irregularly shaped valve plate of the shock absorber:

[0076] S1. The stamping strip 10 is placed on the processing table 2 in advance, and the stamping strip 10 is conveyed by two sets of conveying structures 204;

[0077] S101. If the stamped strip 10 is placed on the upper part of the processing table 2: first place the stamped strip 10 on the processing table body 201, and insert both sides of the stamped strip 10 into the conveying groove 2022 and contact the conveying assembly 2045.

[0078] S102. When conveying the stamped strip 10: two motors 2042 are turned on simultaneously. Each motor 2042, through the cooperation of two second transmission gears 2046, can drive one of the rotating rods 2041 to rotate the same number of times each time. Since the two first transmission gears 2043 are connected by the same chain 2044, one of the rotating rods 2041 can drive the other rotating rod 2041 to rotate synchronously through the cooperation of the first transmission gear 2043 and the chain 2044. This allows each rotating rod 2041 to drive two conveying components 2045 to work, so that the conveying components 2045 can convey the stamped strip 10.

[0079] Working principle of conveying assembly 2045: When the rotating rod 2041 drives the main conveying wheel 20451 to rotate, the main conveying wheel 20451 and the auxiliary conveying wheel 20452 can rotate in a relative manner through the cooperation of two gears 20454, so as to convey the stamped strip 10 clamped between the main conveying wheel 20451 and the auxiliary conveying wheel 20452.

[0080] Step 2: The stamping device stamps the stamping strip 10; the stamped workpiece forms the special-shaped valve plate of the shock absorber;

[0081] When stamping the stamping strip 10: the hydraulic cylinder 14 is activated, which drives the lifting component 4 to move downward (it should be noted that when the lifting component 4 moves downward, the sliding component 902 is located inside the downward guide groove 1101). The lifting component 4 drives the stamping component 5 to move downward, and the stamping component 5 drives the rotary stamping structure 6 to move downward and stamp the stamping strip 10, thereby completing the stamping of the irregular valve plate. The finished irregular valve plate falls into the collection box 13 through the stamping groove 702 and the drop groove 705 in sequence, which plays a collection role, reduces the collection work of the staff, and provides convenience for the staff.

[0082] The stamping principle of the rotary stamping structure 6: When the stamping part 5 drives the stamping connector 603 to press downward, the stamping connector 603 can drive the stamping head 604 to move downward through the lifting column 602. Several driving rods 607 can slide downward inside the driving hole 606 respectively. The stamping head 604 can stamp the stamping strip 10.

[0083] It is worth noting that as the lifting component 4 moves downward, due to the shallow-to-deep interior of the downward guide groove 1101, the pressure exerted by the inner bottom wall of the downward guide groove 1101 on the telescopic shaft 9022 continuously increases. The telescopic shaft 9022 continuously moves into the interior of the fixed cylinder 9021 and applies pressure to the elastic support element 9023, causing the elastic support element 9023 to change from its original state to a compressed state. When the lifting component 4 moves downward to the bottom, the sliding component 902 can switch from the downward guide groove 1101 to the top of the upward guide groove 1102. Since the depth of the top of the upward guide groove 1102 is greater than the depth of the top of the downward guide groove 1101, the elastic support element 9023 can return from the compressed state to its original state and push the telescopic shaft 9022 out of the interior of the fixed cylinder 9021, so that one end of the telescopic shaft 9022 abuts against the inner bottom wall of the top of the upward guide groove 1102.

[0084] Step 3: The stamping device is reset after stamping to prepare for the next stamping.

[0085] When the stamping device is reset: the hydraulic cylinder 14 can push the lifting component 4 upward (it should be noted that when the lifting component 4 moves upward, the sliding component 902 is located inside the upward guide groove 1102). The lifting component 4 can drive the rotary stamping structure 6 to reset through the stamping component 5. The lifting component 4 can drive the rotary stamping structure 6 and the rotary stamping table 7 to rotate and adjust through the cooperation of two sets of clutch drive structures 8.

[0086] The reset principle of the rotary stamping structure 6: When the stamping part 5 drives the stamping connector 603 to move upward, due to the setting of the annular limiting groove 6032 and the annular protrusion 504, the stamping part 5 will not separate from the stamping connector 603. The stamping connector 603 drives the stamping head 604 to move upward through the lifting column 602, so that the stamping head 604 can retract into the interior of the rotating drum 601, thereby completing the reset.

[0087] It is worth noting that when the lifting component 4 moves upward, it is divided into three stages: the initial stage, the middle stage, and the final stage.

[0088] like Figure 20 As shown in the left figure: When the lifting component 4 is in the initial stage during the upward movement: the telescopic shaft 9022 can move in advance towards the stamping box 3 according to the motion trajectory set by the upward guide groove 1102. The telescopic shaft 9022 can push the "U" shaped component 901 towards the stamping box 3 through the fixed cylinder 9021, so that the "U" shaped component 901 can simultaneously drive the two telescopic cylinders 802 towards the stamping box 3, so that the rotating shaft 801 and the telescopic cylinder 802 can retract towards each other. At this time, the drive gear 803 and the rack 402 are located on the same vertical line.

[0089] like Figure 20 As shown in the middle diagram: When the lifting component 4 is in the middle section during its upward movement: the lifting component 4 drives the two racks 402 to move upward and mesh with the drive gears 803 respectively, so that the racks 402 can drive the drive gears 803 to rotate. The drive gears 803 drive the main bevel gears 804 to rotate in sequence through the telescopic cylinder 802 and the rotating shaft 801. The two main bevel gears 804 drive the rotary stamping structure 6 and the rotary stamping table 7 to rotate synchronously through the secondary bevel gears 805 respectively, thereby completing the function of rotation adjustment.

[0090] The rotation adjustment principle of the rotary stamping structure 6: When the secondary bevel gear 805 drives the rotating drum 601 to rotate inside the stamping box 3, the rotating drum 601, through the cooperation of the drive ring 605 and the drive rod 607, can drive the lifting column 602 to rotate, so that the lifting column 602 can drive the stamping connector 603 and the stamping head 604 to rotate respectively, so that the stamping connector 603 can rotate at the bottom end of the stamping part 5, thus completing the rotation adjustment of the rotary stamping structure 6.

[0091] The rotation adjustment principle of the rotary stamping table 7: When the secondary bevel gear 805 drives the rotating seat 703 to rotate, the rotating seat 703, through the cooperation of several insertion holes 707 and several insertion shafts 706, can drive the stamping base 701 to rotate in the mounting hole 2047, so that the stamping groove 702 on the stamping base 701 is correspondingly set with the stamping head 604, thereby completing the rotation adjustment of the rotary stamping table 7.

[0092] like Figure 20 As shown in the right figure: When the lifting component 4 is in the final stage of moving upward: At this time, the rack 402 and the drive gear 803 have disengaged vertically. The telescopic shaft 9022 moves towards the slide rail 15 according to the motion trajectory set by the upward guide groove 1102. The telescopic shaft 9022 can pull the "U" shaped component 901 towards the slide rail 15 through the fixed cylinder 9021, so that the "U" shaped component 901 can pull the two telescopic cylinders 802 at the same time, so that the telescopic cylinders 802 and the rotating shaft 801 are in the extended state. At this time, the drive gear 803 and the rack 402 are in a staggered arrangement.

[0093] It should be noted that as the lifting component 4 moves upward, because the interior of the upward guide groove 1102 is deeper at the top and shallower at the bottom, the pressure exerted by the inner bottom wall of the upward guide groove 1102 on the telescopic shaft 9022 continuously increases. The telescopic shaft 9022 continuously moves into the interior of the fixed cylinder 9021 and applies pressure to the elastic support element 9023, causing the elastic support element 9023 to change from its original state to a compressed state. When the lifting component 4 moves upward to the top, the sliding component 902 switches from the upward guide groove 1102 to the bottom end of the downward guide groove 1101. Since the depth of the bottom end of the downward guide groove 1101 is greater than the depth of the bottom end of the upward guide groove 1102, the elastic support element 9023 can change from a compressed state to its original state and push the telescopic shaft 9022 out of the interior of the fixed cylinder 9021, so that one end of the telescopic shaft 9022 contacts the inner bottom wall of the bottom end of the downward guide groove 1101.

[0094] Step 4: During the resetting process of the stamping device, the stamping strip 10 can be conveyed in a progressive manner through the conveying structure 204 (the conveying method can be referred to the working principle of the first step, and will not be described in detail again); so that the unstamped area on the stamping strip 10 is conveyed to the bottom of the rotary stamping structure 6 to prepare for the next stamping.

[0095] If the stamping device is used to continuously stamp the stamping strip 10, the working principle of the stamping device is to repeatedly operate from the second step to the fourth step (the working principle of the second step to the fourth step has been described above and will not be repeated in detail), thereby enabling the batch production of irregular valve plates and improving the production efficiency of irregular valve plates.
