Automobile stamping device with rotating feeding mechanism

Abstract

This invention discloses an automotive stamping device with a rotating feeding mechanism, relating to the field of stamping technology. It includes a stamping frame unit, comprising a frame body and a stamping processing unit rotatably mounted on the side of the frame body. A reciprocating lifting source is activated, causing the processing cavity and a pre-pressing strip at the bottom of the processing cavity to move downwards. This allows the pre-pressing strip to contact the sheet metal first, pre-pressing the sheet metal at the center of the outer side of the concave cavity to form a strip groove. If the number of concave cavities exceeds the number of pre-pressing strips, the processing cavity can be rotated to allow the pre-pressing strips to press. This facilitates subsequent stamping of the sheet metal by the concave cavity, ensuring that the stamping stress of the stamping die on the sheet metal is partially concentrated inside the strip groove. This prevents excessive stress concentration in the stamping area (groove area) of the concave cavity due to stamping die pressure, reducing the possibility of groove contour deformation.

Description

Technical Field

[0001] This invention relates to the field of stamping technology, and in particular to an automotive stamping device with a rotary feeding mechanism. Background Technology

[0002] In the automobile manufacturing process, stamping technology is widely used in the production of gears for various automotive parts. Gears formed by stamping can improve work efficiency, especially in the stamping of thin plate gears, where stamping can effectively control precision and efficiently complete gear production.

[0003] Chinese patent CN202320681333.X discloses a gear stamping die, including an upper die and a lower die for forming a gear by mutual cooperation. The lower die includes a first combined die and a second combined die that can be separated from each other. A base is provided at the bottom of the lower die, and a movable seat is movably connected to the top of the base and below the lower die. After the gear is stamped, an electric telescopic rod drives the movable seat and the lower die to separate from below the upper die. Under the guidance of a guide rod, the lower die separates into the first combined die and the second combined die and moves in a direction away from each other. At this time, the gear can be quickly removed from the lower die from a position outside the upper die without pushing it from below the lower die. The bottom of the lower die has no opening, which improves the accuracy of gear stamping and the safety of gear removal.

[0004] The aforementioned patents and prior art have the following problems:

[0005] In existing gear stamping processes, molds are used to form the sheet metal inside the mold. However, when stamping the tooth groove, especially thin sheet metal, stress accumulation can easily occur in the tooth groove, causing stress deformation at the stamping location. This results in poor gear forming quality. Furthermore, after stamping, all surfaces of the gear need to be finished. Existing grinding heads are inserted vertically into the tooth groove for grinding, which can lead to improper contact with the gear and slight deformation. Moreover, a single grinding head cannot quickly grind and finish all surfaces of the gear, resulting in low processing efficiency. Summary of the Invention

[0030] The back plate, mounting base plate, mounting top plate, and grinding strips together form a receiving chamber. The mounting base plate and mounting top plate are both mounted with staggered plates on their surfaces inside the receiving chamber. Several moving grooves are provided on the sides of the staggered plates. Movable shafts are slidably arranged inside the moving grooves. The portion of the movable shaft passing through the connecting plate is rotatably connected to the processing grinding roller. A trigger plate is fixedly connected to the opposite surface of the connecting plate and the staggered plates. A spring support is elastically arranged between the bottom of the trigger plate and the staggered plates. A control plug is movably arranged on the inner side of the trigger plate.

[0031] The beneficial effects of this invention are:

[0032] 1. By continuously hammering the tooth groove of the stamping gear with a punching component, the residual stress after pre-stamping guided by the pressure bar is further eliminated. During this process, the punching component is inserted flat into the tooth groove, making the tooth groove less prone to deformation. The grinding roller retracts into the interior of the punching component, minimizing interference with its insertion. After the punching component is inserted into the tooth groove, its up-and-down movement is controlled, causing the mounting base plate and mounting top plate to move up and down within the tooth groove in conjunction with the grinding bar column. This longitudinally grinds the tooth groove surface. As the punching component retracts outward, the insert block synchronously presses the grinding roller protruding, bringing it into contact with the tooth groove surface. During the retraction of the punching component, the grinding roller laterally rolls on the tooth groove surface, and the grinding waste is unidirectionally... The grinding wheel is pulled out, thus fully polishing the surface of the tooth groove. Through the rotating processing chamber, the retracting grinding bar polishes the teeth of the stamped gear. As the grinding bar rotates with the processing chamber, it drives the trigger plate to move, causing the connecting ring plate and protrusion to continuously polish the upper and lower surfaces of the stamped gear. This ensures that all surfaces of the gear are polished in conjunction after the stress is relieved during stamping, improving work efficiency. After the gear is polished, the gear and residual material can be removed manually, or the gear and residual material that have fallen to the bottom of the frame can be clamped out step by step by the moving clamping of the extrusion clamping plate through the rotating clamping of the storage frame and transferred to the surface of the storage plate for subsequent processing.

[0033] 2. Start the reciprocating lifting source, which drives the processing chamber and the pre-pressing strip at the bottom of the processing chamber to move downwards. This causes the pre-pressing strip to contact the sheet metal first, and the sheet metal at the middle position of the outer side of the concave cavity is pre-pressed by the pre-pressing strip to form a strip groove. The stamping waste enters the bottom of the discharge port through the slot. If the number of concave cavities is greater than the number of pre-pressing strips, the processing chamber can be rotated to make the pre-pressing strips press. This makes it easier for the concave cavities to press the sheet metal later. The stamping stress of the concave cavity of the stamping die will be partially concentrated in the inside of the strip groove. This prevents the stamping area of ​​the concave cavity, i.e. the tooth groove area, from being excessively concentrated in the stamping position of the concave cavity and the sheet metal due to the stamping die, thus reducing the deformation of the tooth groove contour.

[0034] Third, when the control block is inserted into the tooth groove, the tooth groove wall of the stamping gear will squeeze the processing roller and the movable shaft to retract into the receiving chamber along the moving groove. This prevents the processing roller on the side wall of the stamped part from excessively contacting the tooth groove wall when the stamped part is inserted into the tooth groove. Therefore, the contact between the stamped part and the tooth groove wall gradually approaches, and the force distribution is more uniform. This is different from the existing grinding head that is inserted vertically into the tooth groove, which is prone to uneven tooth grooves with excessive local force on one side, resulting in the risk of indentation or damage to the edge of the tooth groove.

[0035] Fourth, the external rotation drive source rotates, causing different second protruding sections and second recessed sections to contact the first moving member. When the first moving member moves along the second protruding section to the inside of the second recessed section, the concavity of the second recessed section will cause the first moving member to pull the first movable rod and the punching member outward under the elastic recovery of the first elastic member. Thus, through the rotation of the external rotation drive source, the second protruding section and the second recessed section cause the punching member to reciprocate along the vertical plate, causing the punching bar at the front end of the punching member to continuously hammer the bottom of the tooth groove, causing the bottom of the tooth groove to be continuously impacted and hardened, and improving the stress distribution at this position. At the same time, the small burrs at the bottom of the tooth groove are also smoothed out under the impact of the punching bar, thereby improving the gear quality.

[0036] 5. The shapes of the mounting base plate and mounting top plate combined with the grinding strip are aligned with the shape of the tooth groove after being inserted into it. Then, after the grinding strip has finished hammering the tooth groove, the second protruding section pushes the punching part and the grinding strip at its front end into the tooth groove. At this time, the processing roller is squeezed into the interior of the mounting base plate, and the reciprocating lifting source controls the up and down movement of the processing chamber, so that the grinding strip, the mounting base plate and the mounting top plate continuously grind the surface of the tooth groove, so that the surface of the tooth groove is ground vertically.

[0037] 6. Make the inner and outer rotation drive sources rotate at the same speed, so that the first protruding section moves to the first recessed section and the second protruding section moves to the second recessed section, so that the punching part and the control block retract outward synchronously. During the retraction of the punching part, the control block is always in contact with the trigger plate, so as to squeeze the processing grinding roller protruding into the inside of the receiving chamber, so that when the punching part retracts, it drives the processing grinding roller to grind the tooth groove wall laterally.

[0038] 7. The main rotation source is started, which drives the driven component to rotate through the main drive component. The driven component drives the reciprocating lifting source and the processing chamber at its bottom to rotate. As the punching component rotates and moves to the next tooth groove, the grinding bar at the front end of the punching component contacts the tooth surface of the stamping gear. Combined with the rotation of the processing chamber, the grinding bar polishes the tooth surface of the stamping gear.

[0039] 8. As the grinding bar rotates with the processing chamber, its protruding part from the stamping gear will drive the corresponding protruding trigger plate of the stamping gear's teeth to move accordingly. This causes the grinding bar to squeeze and drive the trigger plate to move to the middle of the next adjacent tooth after it passes over the teeth of the stamping gear. This allows the grinding bar to drive the trigger plate to rotate, which in turn causes the protruding block and connecting ring plate at the bottom of the trigger plate to rotate around the intermediate pressure plate. This allows the connecting ring plate and the protruding block, preferably positioned opposite the stamping gear, to grind the upper and lower surfaces of the stamping gear's grooves and teeth, thereby further improving the surface treatment effect of the gear.

The two protective plates 20423 protect and restrict the connection between the positioning block 20421 and the trigger plate 20422, preventing the positioning block 20421 and the trigger plate 20422 from being excessively offset when the trigger plate 20422 is pushed by the grinding bar 2024, thereby affecting the connection stability of the positioning block 20421 and the trigger plate 20422.

A mounting base plate 2022 is fixedly connected to the bottom surface of the back plate 2021, and a mounting top plate 2023 is fixedly connected to the top surface of the back plate 2021. Both the mounting base plate 2022 and the mounting top plate 2023 have polished surfaces on their sides.

The surface of the grinding strip 2024 is provided with a polished surface.

[0083] The back plate 2021, mounting base plate 2022, mounting top plate 2023, and grinding strip 2024 together form a receiving chamber 2025. The mounting base plate 2022 and mounting top plate 2023 are symmetrical about the center of the receiving chamber 2025. The surfaces of the mounting base plate 2022 and mounting top plate 2023 inside the receiving chamber 2025 are each equipped with staggered plates 206. The sides of the staggered plates 206 are provided with several moving grooves 2061. The mounting base plate 2022 and mounting top plate 2023 are each provided with moving grooves 2061 on the surface of the receiving chamber 2025. An internal sliding movable shaft 2071 is provided.

A control insert 205 is movably provided on the inner side of the trigger plate 2073. A grinding surface is provided on the surface of the connecting ring plate 2041 and the protrusion 2042 opposite to the plate. The grinding surface has the same surface structure as the file.

[0084] It should be noted that the bottom clamp lifting source 10122, the rotating clamp source 10231, the reciprocating lifting source 10321, the top clamp lifting source 1033, and the stamping drive source 1034 are preferably cylinders or hydraulic cylinders, and are controlled by a unified PLC and encoder and powered by an external power supply. The loading and turning source 102, the main rotation source 103, the inner rotation drive source 2011, and the outer rotation drive source 2012 are preferably servo motors, and are controlled by a unified PLC and encoder and powered by an external power supply.

[0085] Operation process:

[0086] like Figure 1-2 As shown, by placing the sheet material to be processed into the storage frame 1023 on top of the storage plate 1011, the rotating clamp source 10231 is activated, causing the rotating clamp source 10231 to push the extrusion plate 10232 into contact with the sheet material, thereby fixing the sheet material between the storage frame 1023 and the extrusion plate 10232.

[0087] Restart the loading and turning source 102, which drives the turning shaft 1022 to rotate via the linkage 1021. The turning shaft 1022 then drives the storage frame 1023 to turn, thus turning the storage frame 1023 between the bottom template 1015 and the stamping die 208. This completes the rotational loading of the sheet metal, reducing the movement of the worker's arm between the dies and improving the safety of the stamping process. It should be noted that after the storage frame 1023 turns, the bottom template 1015 is located at the bottom of the sheet metal. At this time, the rotating clamp source 10231 controls the clamping plate 10232 to retract briefly, so that the sheet metal falls on top of the bottom template 1015. Then, the rotating clamp source 10231 is restarted to clamp again.

[0088] like Figure 2 and Figure 4 as well as Figure 15 As shown, the reciprocating lifting source 10321 is restarted, causing the reciprocating lifting source 10321 to move the processing chamber 201 and the pre-pressing strip 2013 at the bottom of the processing chamber 201 downwards. This causes the pre-pressing strip 2013 to contact the plate first, so that the plate at the position corresponding to the middle of the outer side of the concave cavity 2082 is pre-pressed by the pre-pressing strip 2013 to form a strip groove. The stamping waste enters the bottom of the discharge port 1012 through the slot 10151. If the number of concave cavities 2082 is greater than the number of pre-pressing strips 20321, the process is complete. The number 013 allows the rotating processing cavity 201 to press the first pressing strip 2013, which facilitates the subsequent pressing of the plate by the inner cavity 2082. When the inner cavity 2082 of the stamping die 208 presses the plate, the pressing stress of the inner cavity 2082 of the stamping die 208 on the plate will be partially concentrated in the inside of the strip groove. This prevents the stamping area of ​​the inner cavity 2082, i.e. the tooth groove area, from being excessively concentrated in the stamping position of the inner cavity 2082 and the plate due to the stamping of the stamping die 208, thus reducing the deformation of the tooth groove contour.

[0089] like Figure 2-4 and Figure 8 as well as Figure 15 As shown, when the pre-pressing strip 2013 presses the sheet metal, it will drive the bottom stamping waste through the slot 10151 to the inside of the discharge port 1012. Then, the pre-pressing strip 2013 returns to the top of the frame 101, and the stamping drive source 1034 is started. The stamping drive source 1034 drives the connecting arm plate 10341 and the stamping die 208 to move down. The moving stamping die 208 stamps the sheet metal after the pre-pressing strip 2013 has processed it, so that the sheet metal forms a gear shape inside the stamping die 208, thereby completing the stamping of the gear.

[0090] It should be noted that the projection position of the pre-pressing strip 2013 is located in the middle of the outer side of the concave cavity 2082, so that the strip groove formed by the pre-pressing strip 2013 is located in the middle of the stamping area of ​​the concave cavity 2082, and the stress of the tooth groove part of the gear formed by the concave cavity 2082 during the stamping process is more symmetrically concentrated in the strip groove.

[0091] like Figure 1-3 and Figure 15 When the stamping die 208 stamps the sheet metal, the bottom clamping lifting source 10122 at the bottom of the frame 101 and the top clamping lifting source 1033 at the top of the frame 101 are activated, causing the intermediate pressure circular plate 203 at the top of the bottom clamping lifting source 10122 and the intermediate pressure circular plate 203 at the bottom of the top clamping lifting source 1033 to move closer to the gear formed by the sheet metal stamping (hereinafter, the gear formed by the sheet metal stamping is collectively referred to as the stamping gear), so that the upper and lower surfaces of the stamping gear are clamped by the intermediate pressure circular plate 203 and the processing ring 204. When the upper and lower surfaces of the gear are clamped by the two sets of intermediate pressure circular plates 203, After being clamped by the 03 and the processing ring 204, the two sets of intermediate pressure circular plates 203 and the processing ring 204 move upward, causing the stamping gear to disengage from the inside of the stamping die 208, thereby completing the demolding of the stamping gear. This reduces the obstruction of the stamping die 208 on the side surface of the stamping gear during the subsequent surface treatment of the stamping gear. In addition, the clamping of the stamping gear by the upper and lower intermediate pressure circular plates 203 and the processing ring 204 also reduces the accidental rotation of the gear during the demolding process, so that the surface treatment of the stamping gear can be more precise in the subsequent process.

[0092] like Figure 6 and Figure 15As shown, it should be noted that the outer contours of the intermediate pressure plate 203 and the processing ring 204 match the inner contours of the stamping die 208, thus facilitating the upward movement of the intermediate pressure plate 203 and the processing ring 204. This allows the bottom intermediate pressure plate 203 and the processing ring 204 to push the stamping gear out of the stamping die 208. The trigger bar 20422 on the outer side of the processing ring 204 is hinged to the surface of the protrusion 2042. Thus, when the processing ring 204 is raised, it will be squeezed downward and flipped to the bottom of the protrusion 2042 by the stamping die 208. Therefore, when the processing ring 204 is raised, the trigger bar 20422 will not form an obstruction or interference with the stamping die 208, thereby ensuring the smooth demolding of the stamping gear.

[0093] like Figure 4 and Figure 9-11 As shown, after the stamping gear completes demolding under the lifting of the upper and lower intermediate pressure circular plates 203, the processing cavity 201 moves down to the side of the stamping gear. At this time, the punching part 202 is directly opposite the outer side of the stamping gear tooth groove, and the punching part 202 does not contact the stamping gear. This causes the external rotation drive source 2012 to start, which drives the external transmission ring 20154 to rotate through the external rotation gear 20121. This causes the second protrusion section 20151 on the inner side of the external transmission ring 20154 to rotate, so that the initially located... The first moving member 20212 inside the second recessed section 20152, under the rotation of the outer transmission ring 20154, causes the second protruding section 20151 to contact the first moving member 20212, causing the second protruding section 20151 to protrude inward relative to the second recessed section 20152, pushing the first moving member 20212 to move inward, causing the first elastic member 20213 to be squeezed, thereby causing the first moving member 20212 to drive the first movable rod 20211 and the control insert 205 to be inserted into the tooth groove of the stamping gear;

[0094] When the control block 205 is inserted into the tooth groove, the tooth groove wall of the stamping gear will squeeze the processing roller 207 and the movable shaft 2071 to retract into the receiving chamber 2025 along the moving groove 2061. This prevents the processing roller 207 on the side wall of the stamping part 202 from excessively contacting the tooth groove wall when the stamping part 202 is inserted into the tooth groove. Therefore, the contact between the stamping part 202 and the tooth groove wall is gradually closer, and the force distribution is more uniform. This is different from the existing grinding head that is inserted vertically into the tooth groove, which is prone to uneven tooth grooves with excessive local force on one side, resulting in the risk of indentation or damage to the edge of the tooth groove.

[0095] During the above process, the external rotation drive source 2012 rotates, causing the different second protruding segments 20151 and second recessed segments 20152 to contact the first moving member 20212. When the first moving member 20212 moves along the second protruding segment 20151 into the second recessed segment 20152, the recess of the second recessed segment 20152 causes the first moving member 20212 to pull the first movable rod 20211 and the punching member under the elastic recovery of the first elastic member 20213. 202 moves outward, and thus, through the second protruding section 20151 and the second recessed section 20152, with the rotation of the external rotation drive source 2012, the punching member 202 moves back and forth along the vertical plate 20131, causing the punching bar 2024 at the front end of the punching member 202 to continuously hammer the bottom of the tooth groove, so that the bottom of the tooth groove is continuously impacted and hardened, and the stress distribution at this position is improved. At the same time, the small burrs at the bottom of the tooth groove are also smoothed out under the impact of the punching bar 2024, thereby improving the gear quality.

[0096] It should be noted that the height of the grinding bar 2024 is greater than the height of the stamping gear, and the grinding bar 2024 is distributed symmetrically in the middle of the tooth groove.

[0097] Alternatively, the mounting base plate 2022 and mounting top plate 2023 can be combined with the grinding bar 2024 in a shape that matches the shape of the tooth groove after being inserted into it. Then, after the grinding bar 2024 has finished hammering the tooth groove, the second protruding section 20151 pushes the punching member 202 and the grinding bar 2024 at its front end into the tooth groove. At this time, the processing roller 207 is squeezed into the mounting base plate 2022, and the reciprocating lifting source 10321 controls the processing chamber 201 to move up and down, so that the grinding bar 2024, the mounting base plate 2022 and the mounting top plate 2023 continuously grind the surface of the tooth groove, so that the surface of the tooth groove is ground vertically.

[0098] It should be noted that when the punching part 202 is inserted into the tooth groove, the control block 205 does not contact the trigger plate 2073, that is, the second moving part 2052 is located on the surface of the first recessed section 20142, so that the second elastic part 2053 is in an uncompressed state, thereby facilitating the tooth groove wall extrusion processing roller 207 to retract into the receiving chamber 2025 along the moving groove 2061 with the movable shaft 2071.

[0099] like Figure 4 and Figure 9-14As shown, when the punch 202 is about to move outward from inside the tooth groove, the inner rotation drive source 2011 is activated, driving the inner rotation gear 20111 to rotate. The inner rotation gear 20111 drives the middle transmission ring 20143 to rotate, causing the first protruding section 20141 and the first recessed section 20142 on the inner side of the middle transmission ring 20143 to rotate along with the first recessed section 20142. The first recessed section 20142, which initially contacts the second moving member 2052, rotates along with the middle transmission ring 20143. The first protruding section 20141 gradually contacts the second moving member 2052, thereby pushing the second moving member 2052 and the second movable rod 2051 into the receiving chamber 2025. This causes the second movable rod 2051 to push the control plug 205 into the side of the trigger plate 2073, and the control plug 205 pushes the trigger plate 2073 and the processing grinding roller 207 outward, thereby bringing the processing grinding roller 207 into contact with the tooth groove surface.

[0100] At this time, the second moving part 2052 is located at the protrusion apex of the first protruding section 20141, and the first moving part 20212 is located at the protrusion apex of the second protruding section 20151. This causes the inner rotation drive source 2011 and the outer rotation drive source 2012 to rotate at the same speed, causing the first protruding section 20141 to move towards the first recessed section 20142 and the second protruding section 20151 to move towards the second recessed section 20152. As a result, the punching part 202 and the control insert 205 move outward synchronously. During the retraction of the punching part 202, the control insert 205 is always in contact with the trigger plate 2073, thereby squeezing the processing roller 207 out of the interior of the receiving chamber 2025. This causes the punching part 202 to drive the processing roller 207 to grind the tooth groove wall laterally when it retracts.

[0101] Of course, in order to make the retraction and forward positions of the insert 205 and the punching member 202 more consistent, the initial positions of the first protruding segment 20141 and the second protruding segment 20151 are the same and both are coplanar with the opposite surface of the punching member 202, and the initial positions of the second recessed segment 20152 and the first recessed segment 20142 are the same and both are coplanar with the opposite surface of the punching member 202.

[0102] After the punching component 202 and the processing roller 207 finish grinding the tooth groove, the punching component 202 retracts to the outside of the stamping gear. At this time, the second moving component 2052 is located inside the first recessed section 20142 and the first moving component 20212 is located inside the second recessed section 20152. At this time, the main rotation source 103 is started, so that the main rotation source 103 drives the driven component 1032 to rotate through the main transmission component 1031. The driven component 1032 drives the reciprocating lifting source 10321 and the processing cavity 201 at its bottom to rotate. As the punching component 202 rotates and moves to the next tooth groove with the processing cavity 201, the punching and grinding bar 2024 at the front end of the punching component 202 contacts the tooth surface of the stamping gear. Combined with the rotation of the processing cavity 201, the punching and grinding bar 2024 grinds the tooth surface of the stamping gear.

[0103] As the grinding bar 2024 rotates with the processing chamber 201, the portion protruding from the stamping gear drives the corresponding protruding trigger plate 20422 of the stamping gear's teeth to move accordingly. This causes the grinding bar 2024 to press and move the trigger plate 20422 to the middle of the next adjacent tooth after it passes over the teeth of the stamping gear. Consequently, the grinding bar 2024, by moving the trigger plate 20422, causes the protruding block 2042 at the bottom of the trigger plate 20422 and the connecting ring plate 2041 to rotate around the intermediate pressure plate 203. The connecting ring plate 2041 and the protrusion 2042 are preferably positioned opposite to the grinding surfaces of the stamping gear to grind the upper and lower surfaces of the tooth grooves and teeth of the stamping gear, thereby further improving the surface treatment effect of the gear. It should be noted that during rotation, the grinding bar 2024 will first push the trigger bar 20422 in contact with it past the tooth groove to be processed and transfer it to the middle of the next tooth. When it returns to the middle of the tooth groove to be processed, the inner cavity 2043 is always facing the tooth groove of the stamping gear, which facilitates the up and down movement of the stamping part 202 through the inner cavity 2043.

[0104] In summary, by continuously hammering the tooth groove of the stamping gear with the punching component 202, the residual stress after pre-stamping guided by the pre-pressing strip 2013 is further eliminated. During this process, the punching component 202 is inserted flat into the tooth groove, making the tooth groove less prone to deformation. Furthermore, the processing grinding roller 207 retracts into the interior of the punching component 202, minimizing interference with its insertion. After the punching component 202 is inserted into the tooth groove, its up-and-down movement is controlled, causing the mounting base plate 2022 and mounting top plate 2023, in conjunction with the grinding strip 2024, to move up and down inside the tooth groove, resulting in longitudinal grinding of the tooth groove surface. As the punching component 202 retracts outward, the insert block 205 simultaneously presses the processing grinding roller 207 outward, bringing it into contact with the tooth groove surface. During the retraction of the punching component 202, the processing grinding roller 207 is transversely rolled on the tooth groove surface, further enhancing the grinding effect. Waste material is carried out unidirectionally, thus fully polishing the surface of the tooth groove. Through the rotating processing chamber 201, the retracted grinding bar 2024 polishes the teeth of the stamped gear. As the grinding bar 2024 rotates with the processing chamber 201, it drives the trigger plate 20422 to move, causing the connecting ring plate 2041 and the protrusion 2042 to continuously polish the upper and lower surfaces of the stamped gear with the movement of the grinding bar 2024. This ensures that all surfaces of the gear are polished in conjunction after the stress is relieved during stamping, improving work efficiency. After the gear is polished, the gear and residual material can be removed manually, or the gear and residual material that have fallen to the bottom of the frame 101 can be clamped out step by step by the moving clamping of the extrusion clamping plate 10232 through the rotating clamping of the storage frame 1023, and transferred to the surface of the storage plate 1011 for subsequent processing.
