Technical Field

[0001] This invention relates to the field of metal case stamping technology, specifically to a metal case stamping and forming equipment for smartwatches. Background Technology

[0002] With the development of science and technology, various wearable devices have emerged, gaining popularity due to their portability and multifunctionality, especially smartwatches. The metal casing of a smartwatch is typically made by stamping a metal disc; its production efficiency and forming quality directly affect the manufacturing cost and appearance of the smartwatch.

[0003] Existing metal watch case stamping equipment is mostly single-station or semi-automated, requiring manual loading, unloading, and transfer during production. This is not only labor-intensive and inefficient, but also fails to meet the demands of large-scale continuous production. Furthermore, the stamped metal watch case surface often has burrs, which existing equipment typically lacks integrated burr removal functionality, requiring separate post-processing and increasing both the number of steps and equipment investment. Therefore, a new metal watch case stamping and forming equipment for smartwatches is needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a metal case stamping and forming equipment for smartwatches, which solves the problems of manual loading, unloading, part removal, and transfer operations required in the production process of existing metal case stamping equipment, as well as the presence of burrs on the surface of the stamped metal case.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A stamping and forming equipment for metal watch cases of smartwatches, comprising: The frame has multiple guide rings fixedly connected to its top side. A turntable is rotatably connected to the inner circumference of the guide rings. Multiple mold arc disks are rotatably connected to the outer circumference of the top side of the turntable. A hydraulic punch for stamping is provided at the top of the turntable. The hydraulic punch is connected to the frame through a gantry. The stamping die head installed at the drive end of the hydraulic punch and the mold groove of the mold arc disk form the cavity of the stamping die. A guide groove is provided on the top side of the guide ring, which slides against the guide protrusion at one end of the mold arc disk to deflect one of the mold arc disks after it is displaced to the unloading area. The housing is fixedly connected to one side of the turntable, and a positioning seat is fixedly connected to one end. The positioning seat coincides with the mold groove of one of the mold arc disks. An ejection assembly is provided on the bottom side of the positioning seat to eject the stamped metal watch case from the mold groove.

A deflection frame is connected to the top side pivot of the horizontal sliding frame via a torsion spring. A gripping head is fixedly connected to one end of the deflection frame. A gripping assembly for gripping the metal watch case is installed at the bottom end of the gripping head. The gripping assembly is connected to a three-way cylinder. The gripping assembly is controlled by negative pressure suction. After the horizontal sliding frame moves to the designated position, it is triggered by a trigger assembly to release the material. An eccentric rotating wheel is rotatably connected to one side of the housing and is used to drive the burr removal assembly on the top side to remove burrs from the outer surface of the metal case gripped by the die arc plate after stamping. The machine includes two power shafts, each with a drive assembly at one end for controlling the rotation output of both shafts. One power shaft is connected to a rotating shaft via two meshing bevel gears. The bottom side of the turntable is connected to the rotating shaft via two meshing bevel gears. The rotating shaft is rotatably connected to the bottom end of the frame. The other power shaft is connected to a double-sided incomplete gear via two meshing bevel gears. An output rod assembly is installed on one side of the double-sided incomplete gear. The output rod assembly drives the rotation of the guide roller, the displacement of the horizontal sliding frame, and the rotation of the eccentric wheel, respectively. The discharge frame, which is multiple and connected to the frame via a gantry, has a discharge component installed at its bottom for feeding unpressed metal raw materials into the mold slot of an idle mold arc plate on the bottom side. The discharge component is triggered by the displacement of one of the offset mold arc plates through a contact trigger frame.

[0006] Preferably, the ejector assembly includes a guide sleeve rotatably connected to the bottom side of the positioning seat. An ejector head is sleeved inside the guide sleeve. The bottom side of the ejector head and the inner wall of the guide sleeve slide against the guide protrusion at the bottom end of the outer wall of the ejector head through a guide groove with a closed path, so that the top end of the ejector head lifts the stamped metal case. The guide sleeve is connected to the guide roller through a gear with teeth meshing on its outer wall.

[0010] Preferably, the cleaning component includes an offset area and a plush pad. The sliding opening of the offset area is connected to a rolling protrusion at the other end of the deflection frame. The arc-shaped sliding part on the inner wall of the offset area is provided with multiple abutting protrusions. After the other end of the deflection frame abuts against the arc-shaped sliding part, it swings due to the force of the torsion spring at the rotating shaft, causing the bottom end of the broken metal case to contact the plush pad and remove the burrs. A guide frame is fixedly connected to the bottom side of the plush pad. The guide frame slides horizontally with the other side of the case, and the bottom end of the guide frame slides against the guide protrusion on the outer periphery of the eccentric wheel. The guide frame slides horizontally at the top of the frame, and a material discharge port for unloading is provided on one side of the guide frame.

[0011] Preferably, the drive assembly includes a guide wheel rotatably connected to one end of the frame. One side of the guide wheel is driven by a motor. The guide wheel is connected to a transmission wheel through a forward guide groove and a reverse guide groove on its outer wall. A gear ring is rotatably connected to one end of the transmission wheel and the outer wall of the power shaft. The gear ring has ratchet teeth on its inner circumference, and the inner circumference of the ratchet teeth abuts against a pawl. The orientation of the two pawls is opposite to the orientation of the two ratchet teeth. The pawls are rotatably connected to the power shaft through a torsion spring.

[0013] Preferably, the discharge assembly includes a sliding sleeve slidably connected to the bottom side of the discharge frame. One end of the sliding sleeve is connected to a pusher fork via a connecting rod. The pusher fork slides horizontally at the discharge port at the bottom of the discharge frame. The other end of the sliding sleeve is connected to one end of a trigger frame via a connecting rod. The trigger frame is slidably connected to the bottom side of the discharge frame via a spring. The other end of the trigger frame abuts against one of the mold arc plates.

[0014] Preferably, the inside of the discharge frame is connected to a retaining plate by a spring to push and deliver the stacked materials to the discharge point.

[0015] Working principle: During operation, three of the mold arc plates on the top side of the turntable serve as the loading area, stamping area, and unloading area, respectively, and work synchronously. The stamping area uses a hydraulic punch to press the metal disc material inside the mold groove of the bottom mold arc plate. The cavity formed by the stamping die and the mold groove squeezes the metal disc, causing it to deform and thus forming the required smart watch metal case. After the hydraulic punch leaves the mold arc plate, the metal case remains in the original mold groove. When the mold arc disk located in the unloading area is rotated by the turntable, it is offset by the guide groove on the guide ring, causing the mold groove on it to coincide with the positioning seat on the housing. Subsequently, the forward guide groove on the guide wheel driven by the motor meshes with the transmission wheel, causing the transmission wheel to rotate forward. The forward-rotating transmission wheel meshes with two gear rings through the connected gears, and the two gear rings rotate in the same direction. Since the ratchet teeth of the two gear rings are opposite to the corresponding pawls, when one of the gear rings rotates, the ratchet teeth bite the pawl, causing the pawl to rotate forward and be limited. The rotating gear causes the power shaft to rotate. When the other gear ring rotates, it abuts against the pawl through the ratchet teeth. The pawl then lies in the empty area, causing the gear ring to spin freely on the power shaft, thus preventing the power shaft from rotating. At this time, the rotating power shaft drives the double-sided incomplete gear to rotate through two meshing bevel gears. The rotating double-sided incomplete gear continues to drive the rotating rod one to rotate and preferentially meshes with the gear on the rotating rod two. After rotating the rotating rod two at a certain angle, it spins freely and meshes with the gear on the reciprocating screw again, causing the reciprocating screw to rotate several times. First, the rotating rod 2, driven by the transmission, rotates through two meshing bevel gears at its end, which in turn drive the guide rollers to rotate. The rotating guide rollers, in turn, drive the guide sleeve to rotate through the teeth of the gears on the outer wall of the guide sleeve, causing the guide sleeve to be lifted by the ejector head through the guide groove. This ejects the stamped metal case from the mold groove of the mold arc plate and raises the metal case to the bottom of the gripper head, so that it fits against the bottom of the gripper head. At the same time, the rotating guide rollers, driven by the guide groove, complete the downward work of the suction piston head, causing the suction piston head to draw pressure inside the cylinder. This causes the gas to be drawn out of the telescopic piston cylinder through one of the input ends of the three-way cylinder, the connecting pipe, and the branch pipe, creating a negative pressure inside the telescopic piston cylinder. This causes the telescopic piston cylinder to shorten, pulling down the guide plate fixed at the top, which then abuts against the guide groove of the clamping head. This causes multiple clamping heads to move outwards and abut against the inner wall of the concave surface of the metal case, achieving abutment and clamping. Subsequently, the reciprocating screw, driven by the rotation of the transmission, displaces the horizontal sliding frame, causing the horizontal sliding frame to move the structure including the deflection frame and the gripper head. The end of the deflection frame moves along the offset area and, upon reaching the arc-shaped part, abuts against the protrusion on it. After deflecting along the arc-shaped part, the deflection frame deflects several times along the protrusion and immediately returns to its original position under the action of the torsion spring, causing it to produce a reciprocating swinging motion. At this time, the gripper head at the end of the deflection frame is located on the top side of the plush pad. The metal casing at the bottom of the gripper head will contact the plush pad, causing the burrs generated by the stamping deformation on the ground to contact the dense fibers on the surface of the plush pad. During the friction between the burrs and the fiber clusters, the burrs are carried away by the fiber clusters. The rotating rod will synchronously drive the eccentric rotating wheel through two meshing bevel gears to rotate, causing the eccentric rotating wheel to drive the guide frame to move back and forth through the guide protrusion, so that it cooperates with the swinging gripper head to improve the friction effect. When the horizontal sliding frame moves at the offset area of ​​the deflection frame, the abutting part on the horizontal sliding frame will pass the abutting head. At this time, the metal case has not been deburred, and the abutting part on the horizontal sliding frame will abut against the abutting head, causing the abutting head to deflect through the arc-shaped part on one side, causing it to retract downward into the interior of the one-way guide head. After the horizontal sliding frame passes this point, it will be reset by the spring. When the metal case, which has been deburred by the horizontal sliding frame, is reset, the abutting part of the horizontal sliding frame will abut against the side of the abutting head without the arc-shaped part. At this time, the abutting head will rotate on the rotating base, causing the guide protrusion at its bottom to pull... The traction frame is displaced and pulls the valve core connected by the steel wire rope, thereby causing the valve core to disengage from the vent of the valve tube. This allows the negative pressure generated inside the cylinder and the three-way cylinder to be replenished with gas through the vent, restoring the internal air pressure to normal. The telescopic piston cylinder connected to the connecting pipe and the branch pipe will compensate, causing the tension generated by the negative pressure to loosen. At this time, under the action of the arc-shaped part of the offset area, the end of the deflection frame connected to the gripper head is displaced to the top side of the discharge port. At this time, the metal casing will fall into the discharge port for material discharge. The above structure will be reset in the subsequent process through the elastic structure. When the above material feeding is completed, the rotating rod 2 will be engaged and rotated again, causing the guide roller and guide sleeve to rotate again, and driving the suction piston head and ejector head to reset. When the suction piston head resets, because air re-enters, the air pressure inside the suction piston head is greater than the previous air pressure. At this time, the one-way valve diaphragm on the top side of the suction piston head will be pushed open, allowing the excess air to be discharged from here. One of the mold arc disks, whose guide groove on the guide ring has shifted, will contact the trigger frame and move. This causes the trigger frame to move through the connecting rod and pull the sliding sleeve to move. The sliding sleeve then pushes the push fork to move through the connecting rod. The moved push fork will push the metal disc material on one side of it to fall from the bottom outlet of the discharge frame. The metal disc will fall into the mold groove of the idle mold arc disk. After the mold arc disk that contacted the trigger frame moves away from the contact area, the push fork will reset. The new metal disc in the discharge frame will fall to one side of the push fork and wait to be dropped. When the reverse guide groove on the guide wheel meshes with the transmission wheel, the transmission wheel reverses and continues to mesh with the gear ring through the connected gear. The gear ring that previously drove the auxiliary power shaft to rotate idles, and another gear ring drives the power shaft to rotate. This power shaft rotates through two sets of meshing bevel gears and a rotating shaft drive turntable, causing it to change the position of the top mold arc plate, repeating the above-mentioned stamping, loading and unloading work.

[0016] This invention provides a stamping and forming equipment for metal watch cases of smartwatches. It has the following beneficial effects: 1. This invention forms a multi-station synchronous operation mode of feeding, stamping and unloading. Each station operates independently and continuously, which greatly improves production efficiency. At the same time, with the help of automatic unloading and gripping components, the entire process from raw material input to finished product output is automated, reducing manual intervention and labor intensity. It is suitable for continuous stamping and forming production of large batches of metal watch cases for smartwatches.

[0017] 2. This invention shortens the pull-down guide plate by telescopic piston cylinder, so that multiple clamping heads move outward synchronously and abut against the inner wall of the concave surface of the metal case, forming a multi-point abutment clamping, which effectively adapts to the arc-shaped concave structure of the case, grips firmly and does not easily damage the surface of the finished product, and realizes automatic feeding and smooth and accurate unloading.

[0018] 3. In the unloading area, the eccentric rotating wheel drives the guide frame to move back and forth, which drives the burr removal component to remove burrs from the outer surface of the metal casing gripped by the mold arc plate after stamping. The deburring process is integrated into the stamping equipment, eliminating the need for a separate cleaning device. This realizes the integrated operation of stamping, cleaning and collection, saving equipment floor space and production steps. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: This invention provides a metal case stamping and forming equipment for smartwatches, comprising: Please see the appendix Figure 1 - Appendix Figure 3 The machine frame 1 has multiple guide rings 2 fixedly connected to its top side. A turntable 3 is rotatably connected to the inner circumference of the guide rings 2. Multiple die arc disks 6 are rotatably connected to the outer circumference of the top side of the turntable 3. A hydraulic punch 4 for stamping is mounted at the top of the turntable 3. The hydraulic punch 4 is connected to the machine frame 1 via a gantry frame. The stamping die head installed at the drive end of the hydraulic punch 4 and the die groove of the die arc disk 6 constitute the cavity of the stamping die. Please refer to the appendix. Figure 4 The top side of the guide ring 2 is provided with a guide groove, which slides against the guide protrusion at one end of the mold arc disk 6 so that one of the mold arc disks 6 will deflect after being moved to the unloading area. Specifically, all areas related to stamping in this equipment have undergone strength treatment to withstand the pressure during stamping, preventing component deformation and ensuring the quality of subsequent stamping. The stamping die and mold arc plate 6 installed on the drive end of the hydraulic punch 4 can be disassembled and replaced to facilitate the stamping of metal watch cases of different specifications. During operation, three mold arc plates 6 on the top side of the turntable 3 serve as the loading area, stamping area, and unloading area, respectively, and work synchronously. In the stamping area, the hydraulic punch 4 stamps the metal disc raw material inside the mold groove of the bottom mold arc plate 6. The cavity formed by the stamping die and the mold groove compresses the metal disc, causing it to deform and thus forming the required metal watch case. After the hydraulic punch 4 disengages from the mold arc plate 6, the metal case remains in the original mold groove.

[0023] Please see the appendix Figure 5 and attached Figure 6 The housing 7 is fixedly connected to one side of the turntable 3, and one end is fixedly connected to a positioning seat 8. The positioning seat 8 coincides with the mold groove of one of the mold arc disks 6. An ejection assembly is provided on the bottom side of the positioning seat 8 to eject the stamped metal housing from the mold groove. A guide roller 11 is provided on one side of the ejection assembly. The guide roller 11 drives the pneumatic assembly on the top side to perform a suction operation through the synchronous ejection assembly. A three-way cylinder 14 is installed on one side of the pneumatic assembly. The three-way cylinder 14 has two input ends. The ejection assembly includes a guide sleeve 10 rotatably connected to the bottom side of the positioning seat 8. An ejector head 9 is sleeved inside the guide sleeve 10. On the bottom side of 9, the inner wall of the guide sleeve 10 slides against the guide protrusion at the bottom of the outer wall of the ejector head 9 through the guide groove of the closed path, so that the top of the ejector head 9 lifts up the metal case to complete the stamping. The guide sleeve 10 is connected to the guide roller 11 through the gear meshing of the teeth on its outer wall. The suction assembly includes a cylinder 13. The bottom end of the cylinder 13 has a vertically sliding suction piston head 12. One end of the suction piston head 12 slides against the guide groove of the closed path on the outer wall of the guide roller 11 through the guide protrusion. The bottom end of the cylinder 13 is connected to the three-way cylinder 14. A vent is opened on the top side of the cylinder 13. A one-way valve diaphragm is provided at the opening of the vent. Specifically, when the die arc disk 6 located in the unloading area is rotated by the turntable 3, it is offset by the guide groove on the guide ring 2, so that the die groove on it coincides with the position of the positioning seat 8 on the housing 7. The rotating rod 25, which is driven by the transmission, rotates through two meshing bevel gears at its end to drive the guide rollers 11 to rotate. The rotating guide rollers 11 rotate synchronously through the gear meshing with the teeth of the guide sleeve 10 to drive the guide sleeve 10 to rotate, so that the guide sleeve 10 is lifted by the guide groove to drive the ejector head 9 to lift the stamped metal case out of the die groove of the die arc disk 6, and lift the metal case to the bottom of the gripper head 16 so that it fits against the bottom of the gripper head 16.

[0024] Please see the appendix Figure 5 Appendix Figure 7 and attached Figure 8 A horizontal sliding frame 20 slides horizontally on the top side of the housing 7. A deflection frame 21 is connected to the top side pivot of the horizontal sliding frame 20 via a torsion spring. A gripping head 16 is fixedly connected to one end of the deflection frame 21. A gripping component for gripping the metal case is installed at the bottom end of the gripping head 16. The gripping component is connected to the three-way cylinder 14. The gripping component is controlled by negative pressure suction. After the horizontal sliding frame 20 moves to the designated position, it is triggered by the trigger component to release the material. The gripping component includes a guide plate 18 located inside the mold arc plate 6. Multiple telescopic piston cylinders 19 are installed around the guide plate 18. The top side of the multiple telescopic piston cylinders 19 is connected to one of the input ends of the three-way cylinder 14 via a branch pipe and a connecting pipe 15. Multiple clamping heads 17 slide at the bottom end of the mold arc plate 6. The top end of the clamping head 17 slides against the inner circumferential sliding part of the guide plate 18 via a guide groove. Specifically, the rotating guide roller 11 completes the downward pull-down operation through the guide groove driven by the suction piston head 12, causing the suction piston head 12 to draw pressure inside the cylinder 13, so that the gas is drawn out from inside the telescopic piston cylinder 19 through one of the input ends of the three-way cylinder 14, the connecting pipe 15 and the branch pipe, so that the negative pressure is generated inside the telescopic piston cylinder 19, thereby shortening the telescopic piston cylinder 19, pulling down the guide plate 18 fixed at the top, and abutting against the guide groove of the clamping head 17, causing multiple clamping heads 17 to move outward and abut against the inner wall of the concave surface of the metal case, so as to achieve abutment and clamping.

[0025] Please see the appendix Figure 10 - Appendix Figure 12The triggering component includes a rotating seat 31 fixedly connected to the other side of the housing 7. One side of the rotating seat 31 is rotatably connected to a one-way guide head 32 via a torsion spring. The top of the one-way guide head 32 is vertically slidable with an abutment head 33 via a spring. The bottom of the one-way guide head 32 is fitted with a traction frame 34 via a guide protrusion. The traction frame 34 is horizontally slidable on the other side of the housing 7 via a spring. The other input end of the three-way cylinder 14 is connected to a valve pipe 29 via a pipe. The inside of the valve pipe 29 is slidable with a valve core 30 via a spring. The valve core 30 is connected to the side of the three-way cylinder 14 that is close to it via a steel wire rope. The outer wall of the valve pipe 29 is provided with a vent. The middle of the horizontal sliding frame 20 is provided with an abutment part that abuts against the abutment head 33. Specifically, when the horizontal sliding frame 20 moves the deflection frame 21 to the offset region 22, the abutting part on the horizontal sliding frame 20 will pass through the abutting head 33. At this time, the metal case has not been deburred, and the abutting part on the horizontal sliding frame 20 will abut against the abutting head 33, causing the abutting head 33 to deflect through the arc-shaped part on one side, causing it to retract downward into the interior of the one-way guide head 32. After the horizontal sliding frame 20 passes this point, it will be reset by the spring. When the metal case, which has completed the deburring process with the horizontal sliding frame 20, is reset, the abutting part of the horizontal sliding frame 20 will abut against the side of the abutting head 33 without the arc-shaped part. At this time, the abutting head 33 will rotate on the rotating base 31, causing the guide protrusion at its bottom end to... The mechanism starts to move the traction frame 34 and pull the valve core 30 connected by the wire rope, thereby causing the valve core 30 to disengage from the vent of the valve tube 29. This allows the negative pressure generated inside the cylinder 13 and the three-way cylinder 14 to be replenished with gas through the vent, restoring the internal air pressure to normal. The telescopic piston cylinder 19 connected to the branch pipe through the connecting pipe 15 will compensate, causing the tension generated by the negative pressure to loosen. At this time, under the action of the arc-shaped part of the offset area 22, the end of the deflection frame 21 connected to the gripping head 16 is moved to the top side of the discharge port 45. At this time, the metal casing will fall into the discharge port 45 for material discharge. The above structure will be reset in the subsequent process through the elastic structure. When the above material feeding is completed, the rotating rod 25 will be engaged and rotated again, causing the guide roller 11 and guide sleeve 10 to rotate again, and driving the suction piston head 12 and the ejector head 9 to reset. When the suction piston head 12 resets, because air is re-entered, the air pressure inside the suction piston head 12 is greater than the previous air pressure. At this time, the one-way valve diaphragm on the top side of the suction piston head 12 will be opened, allowing the excess air to be discharged from here. Please see the appendix Figure 8 and attached Figure 9An eccentric wheel 26 is rotatably connected to one side of the housing 7. It is used to drive the burr removal assembly on the top side to remove the burrs on the outer surface of the metal case gripped by the die arc plate 6 after stamping. The cleaning assembly includes an offset area 22 and a plush pad 28. The sliding opening of the offset area 22 is connected to the rolling protrusion at the other end of the deflection frame 21. The arc-shaped sliding part of the inner wall of the offset area 22 is provided with multiple abutting protrusions. After the other end of the deflection frame 21 abuts against the arc-shaped sliding part, it swings in conjunction with the force of the torsion spring at the rotating shaft to make the bottom end of the punched metal case contact the plush pad 28 and remove the burrs. A guide frame 27 is fixedly connected to the bottom side of the plush pad 28. The guide frame 27 slides horizontally with the other side of the housing 7, and the bottom end of the guide frame 27 slides against the guide protrusion on the outer periphery of the eccentric wheel 26. The guide frame 27 slides horizontally at the top of the frame 1. A material discharge port 45 for unloading is provided on one side of the guide frame 27. Specifically, the area on the top side of the discharge port 45 is a pre-designed unloading area where the metal watch case after burr removal will fall. The outlet at the bottom of the discharge port 45 can be equipped with a basket for collecting finished products or a conveyor belt to transport the metal watch case to the next production line. The reciprocating screw 23, driven by the rotation of the transmission, displaces the transmission horizontal sliding frame 20, causing the horizontal sliding frame 20 to drive the structure including the deflection frame 21 and the gripper head 16 to move. The end of the deflection frame 21 moves along the offset area 22, and after reaching the arc-shaped part, it abuts against the protrusion on the arc-shaped part, causing the deflection frame 21 to deflect several times along the protrusion after deflecting along the arc-shaped part, and then immediately reset under the action of the torsion spring, causing it to produce a reciprocating swinging motion. At this time, the gripper at the end of the deflection frame 21... The gripping head 16 is located on the top side of the plush pad 28. The metal casing at the bottom of the gripping head 16 will contact the plush pad 28, causing the burrs generated by the stamping deformation on the ground to come into contact with the dense fibers on the surface of the plush pad 28. During the friction between the burrs and the fiber clusters, the burrs will be carried away by the fiber clusters. The rotating rod 24 will synchronously drive the eccentric rotating wheel 26 through two meshing bevel gears to rotate. The eccentric rotating wheel 26 will drive the guide frame 27 to reciprocate through the guide protrusion, so that it can cooperate with the swinging gripping head 16 to improve the friction effect.

[0026] Please see the appendix Figure 13 - Appendix Figure 15There are two drive shafts 38. One end of each drive shaft 38 is equipped with a drive assembly to control the rotation output of both shafts. One drive shaft 38 is connected to a rotating shaft 40 via two meshing bevel gears. The bottom side of the turntable 3 is connected to the rotating shaft 40 via two meshing bevel gears. The rotating shaft 40 is rotatably connected to the bottom end of the frame 1. The other drive shaft 38 is connected to a double-sided incomplete gear 39 via two meshing bevel gears. An output rod assembly is installed on one side of the double-sided incomplete gear 39. The output rod assembly drives the rotation of the guide roller 11 and the position of the horizontal sliding frame 20, respectively. The rotation of the eccentric rotating wheel 26 is driven by a drive assembly including a guide wheel 35 rotatably connected to one end of the frame 1. One side of the guide wheel 35 is driven by a motor. The guide wheel 35 is driven by a transmission wheel 36 through a forward guide groove and a reverse guide groove on its outer wall. The transmission wheel 36 and a gear ring 37 are rotatably connected to the outer wall of one end of the power shaft 38. The inner circumference of the gear ring 37 is provided with ratchet teeth. The inner circumference of the ratchet teeth abuts against a pawl. The orientation of the two pawls is opposite to the orientation of the two ratchet teeth. The pawls are rotatably connected to the power shaft 38 through a torsion spring. The adjacent sides of the two housings 7 are connected to the transmission wheel 36 through meshing gears. Specifically, the forward and reverse guide grooves on the outer wall of the guide wheel 35 will respectively engage with the transmission wheel 36 to rotate forward and reverse. The forward and reverse guide grooves are arranged sequentially, that is, they are cyclically connected on the outer wall of the guide wheel 35. The path length of the forward and reverse guide grooves determines the rotation amplitude of the transmission wheel 36. The forward guide groove on the motor-driven guide wheel 35 engages with the transmission wheel 36, causing the transmission wheel 36 to rotate forward. The forward-rotating transmission wheel 36 engages with two gear rings 37 through the connected gears. The two gear rings 37 rotate in the same direction. Since the ratchet teeth and corresponding pawls of the two gear rings 37 are opposite in direction, when one gear ring 37 rotates, it bites the pawl through its ratchet teeth, causing the pawl to rotate forward. The pawl is limited and drives the power shaft 38 to rotate. When the other gear ring 37 rotates, it abuts the pawl through its ratchet teeth. The pawl lies on the empty area, causing the gear ring 37 to spin freely on the power shaft 38, thus preventing the power shaft 38 from rotating. At this time, the rotating power shaft 38 drives the double-sided incomplete gear 39 to rotate through two meshing bevel gears. The rotating double-sided incomplete gear 39 continuously drives the rotating rod 24 to rotate, and preferentially meshes with the gear on the rotating rod 25. After rotating the rotating rod 25 to rotate a certain angle, it spins freely and meshes with the gear on the reciprocating screw 23 again, causing the reciprocating screw 23 to rotate several times. When the reverse guide groove on the guide wheel 35 meshes with the transmission wheel 36, the transmission wheel 36 reverses and continues to mesh with the gear ring 37 through the connected gear. The gear ring 37 that previously drove the auxiliary power shaft 38 to rotate idles, and another gear ring 37 drives the power shaft 38 to rotate. This causes the power shaft 38 to rotate through two sets of meshing bevel gears and the rotating shaft 40 to drive the turntable 3 to rotate, causing the position of the top mold arc plate 6 to change, repeating the stamping, loading and unloading work.

[0027] Please see the appendix Figure 8 Appendix Figure 13 and attached Figure 16 The output rod assembly includes a reciprocating lead screw 23, a first rotating rod 24, and a second rotating rod 25. The reciprocating lead screw 23, the first rotating rod 24, and the second rotating rod 25 are all rotatably connected inside the housing 7. The bottom end of the horizontal sliding frame 20 is sleeved on the outer wall of the reciprocating lead screw 23. The eccentric wheel 26 is connected to the first rotating rod 24 through two meshing bevel gears. The second rotating rod 25 is connected to the bottom side of the guide roller 11 through two meshing bevel gears. One end of the first rotating rod 24 is fixedly connected to one side of the double-sided incomplete gear 39. Both sides of the double-sided incomplete gear 39 are incomplete meshing structures, and they mesh intermittently with the gear on one end of the reciprocating lead screw 23 and the gear on one end of the second rotating rod 25. The specifications of the double-sided incomplete gear 39 are larger than the specifications of the two gears mentioned above, so it is a speed-increasing transmission. Please see the appendix Figure 1 - Appendix Figure 3There are multiple discharge frames 5, which are connected to the frame 1 via a gantry frame. A discharge assembly is installed at the bottom of each discharge frame 5 to feed unpressed metal raw materials into the mold slots of the idle mold arc disks 6 on the bottom side. The discharge assembly is triggered by the displacement of one of the offset mold arc disks 6 via a contact trigger frame 41. Please refer to the appendix. Figure 17 - Appendix Figure 19 The discharge assembly includes a sliding sleeve 42 slidably connected to the bottom side of the discharge frame 5. One end of the sliding sleeve 42 is connected to a push fork 43 via a connecting rod. The push fork 43 slides horizontally at the discharge port at the bottom of the discharge frame 5. The other end of the sliding sleeve 42 is connected to one end of a trigger frame 41 via a connecting rod. The trigger frame 41 is slidably connected to the bottom side of the discharge frame 5 via a spring. The other end of the trigger frame 41 abuts against one of the mold arc plates 6. The inside of the discharge frame 5 is connected to a clamping plate 44 via a spring to push and deliver the stacked materials to the discharge point. Specifically, one of the mold arc disks 6, which is displaced by the guide groove on the guide ring 2, will abut against the trigger frame 41 and move. This causes the trigger frame 41 to move through the connecting rod and pull the sliding sleeve 42 to move. The sliding sleeve 42 then pushes the push fork 43 to move through the connecting rod. The displaced push fork 43 will push the metal disc raw material on one side of it to fall from the bottom outlet of the discharge frame 5. The metal disc will fall into the mold groove of the idle mold arc disk 6. After the mold arc disk 6 that abuts against the trigger frame 41 leaves the contact area, the push fork 43 will reset. The new metal disc in the discharge frame 5 will fall to one side of the push fork 43 and wait to be dropped.
