Description

Technical Field

[0001] The invention relates to the technical field of precision forming of aluminum alloy plates, and in particular to a stamping forming device for an aluminum vertical cover plate. Background Art

[0002] The vertical cover plate is often installed on the side of the rail vehicle close to the door. Stamping is an indispensable forming process for the production of aluminum vertical cover plates. The stamped aluminum material needs to be clamped during stamping. However, in actual production, the clamping may be unstable, resulting in the vertical cover plate after stamping not meeting the standards. In addition, in order to facilitate the installation of the vertical cover plate, it is necessary to punch mounting holes for bolt insertion at the four corners of the vertical cover plate afterwards, which is a bit inconvenient.

[0003] Chinese patent announcement CN209502671U discloses an aluminum vertical cover plate forming tooling, including a base and a press cylinder, two support plates are symmetrically fixedly installed on the upper surface of the base, and the ends of the two support plates away from the base are fixedly connected to the mounting plates, and the bottom surfaces of the two mounting plates are fixedly installed with telescopic cylinders, and the output ends of the two telescopic cylinders are commonly fixedly connected with a first mounting frame, and a second mounting frame is arranged directly below the first mounting frame, and the left and right ends of the second mounting frame are respectively fixedly connected to the side walls of the two support plates, and the four corners of the bottom surface of the first mounting frame are installed with mounting tubes, and the four corners of the second mounting frame are provided with four through holes matching the four mounting tubes.

[0004] Although the above scheme combines stamping and punching, the existing vertical cover plate is a bent structure. The above scheme first punches the vertical cover plate, and then punches the plate after punching, resulting in deformation of the mounting holes near the bend during the stamping process, causing the mounting holes of the vertical cover plate to have low precision after forming, which in turn leads to the subsequent inability to correctly install the vertical cover plate. In this way, during the stamping process of the plate, it is necessary to ensure that the plate is completely limited in four directions, but the above scheme does not provide a limiting mechanism for limiting the plate, and during the punching operation, since there is no mechanism for limiting the plate, after the punching is completed, the metal burrs remaining at the end of the punching device will push the plate when it is separated from the plate, causing the position of the plate to shift, thus causing the mounting holes to shift after stamping, which in turn leads to the inability to use it normally. If the plate is stamped in advance and then punched, the accuracy of the punching position can be guaranteed. However, the prior art also adopts a processing method of stamping first and then punching. First, the plate is stamped into shape, and then the formed plate is removed and placed in the punching equipment for positioning and punching. In this way, it takes a lot of time to transport the stamped plate and position it before punching, which affects the output of the vertical cover plate.

[0005] If the same equipment is used for the process of stamping first and then punching, the equipment still retains the upper mold and the lower mold, but the punching device needs to be set on the lower mold. This is because the vertical cover plate after stamping has a bent structure, and the upper mold does not have enough space to set the punching device. If the punching device is set on the lower mold, the waste after punching will be stuck in the lower mold and cannot be discharged by itself. Summary of the invention

[0006] In view of the above problems, a stamping and forming equipment for aluminum vertical cover plates is provided. By adopting the method of stamping first and then punching in the same equipment, the upper mold and the lower mold are always in a closed state when the vertical cover plate is punched, thereby avoiding secondary positioning of the vertical cover plate before punching. Compared with the processing method of punching first and then stamping, only one positioning is required for stamping first and then punching, thereby improving the punching efficiency. At the same time, the punching sleeve is arranged on the lower mold, and the first stop position and the second stop position are set for the punching sleeve, so that after the stamping of the vertical cover plate is completed, the punching sleeve moves from the second stop position to the first stop position to complete the punching of the vertical cover plate, and then the punching sleeve moves from the second stop position to the first stop position, so that the waste after punching is moved to the bottom of the lower mold together with the punching sleeve and discharged, thereby overcoming the problem that the waste cannot be discharged when the punching equipment is directly set on the lower mold.

[0007] In order to solve the problems of the prior art, the present invention provides an aluminum vertical cover plate stamping and forming equipment, comprising an upper mold and a lower mold arranged from top to bottom in a vertical direction; a receiving groove corresponding to the mounting hole on the vertical cover plate is obliquely arranged on the bottom of the upper mold, and a punching sleeve is penetrated and arranged along the extension direction of the receiving groove on the lower mold, and the punching sleeve is slidably matched with the lower mold, and the punching sleeve has a first stop position and a second stop position when moving. When the punching sleeve is located at the first stop position, the punching sleeve passes through the lower mold and punches the vertical cover plate, and the punched waste is pushed into the receiving groove by the upper end of the punching sleeve. At this time, the punching sleeve is slidably matched with the receiving groove. When the punching sleeve is located at the second stop position, the upper end of the punching sleeve is located below the lower mold, and there is a gap between the punching sleeve and the lower part of the lower mold, and the waste is discharged through the gap.

[0008] Preferably, a suction cup is movably arranged inside the punching sleeve along the extension direction of the punching sleeve, with the opening end of the suction cup facing the upper end of the punching sleeve, and the suction cup absorbs the waste material under punching.

[0009] Preferably, an inflation bin is fixedly provided at the lower end of the punching sleeve, a pushing plate is slidably provided in the inflation bin along the extension direction of the punching sleeve, the suction cup moves synchronously with the pushing plate, an inflation cavity is formed between the side of the pushing plate away from the punching sleeve and the inflation bin, and a first air pump is provided on one side of the inflation cavity.

[0010] Preferably, a switch valve connected to the suction cup is provided on the side of the push plate away from the suction cup, and the switch valve is opened only when the punching sleeve is in the second stop position. Before the punching sleeve moves from the second stop position to the first stop position, the switch valve is closed.

[0011] Preferably, a ventilation groove interconnected with the accommodating groove is provided in the upper mold, and a second air pump is provided on the ventilation groove for blowing air into the ventilation groove when the punching sleeve leaves the first stop position.

[0012] Preferably, a platform for supporting the lower mold is arranged around the lower mold, and a conveying groove is arranged on the upper part of the platform, and the width of the conveying groove is the same as the length of the vertical cover plate in the width direction of the platform.

[0013] Preferably, a limiting unit is also provided on the platform for limiting the length of the opposing cover plate in the length direction of the platform. The limiting unit includes two groups of limiting rods symmetrically arranged about the lower mold. The two groups of limiting rods rotate toward each other when limiting the opposing cover plate, and the straight-line distance between the two rotation centers of the two groups of limiting rods is the same as the length of the standing cover plate in the length direction of the platform.

[0014] Preferably, a placement seat hinged to the limiting rod is provided on the platform, and a driving unit for driving the limiting rod to rotate is provided at one end of the limiting rod facing the lower mold.

[0015] Preferably, a weight is provided at one end of the limiting rod away from the lower mold.

[0016] Preferably, two groups of rollers are symmetrically arranged on the platform with respect to the lower mold, and the axes of the rollers are parallel to the width direction of the platform.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adopts a method of stamping first and then punching in the same equipment, so that when the vertical cover plate is punched, the upper mold and the lower mold are always in a closed state, avoiding secondary positioning of the vertical cover plate before punching. Compared with the processing method of punching first and then stamping, only one positioning is required for punching after stamping, thereby improving the punching efficiency. At the same time, the punching sleeve is arranged on the lower mold, and the first stop position and the second stop position are set for the punching sleeve, so that after the punching of the vertical cover plate is completed, the punching sleeve moves from the second stop position to the first stop position to complete the punching of the vertical cover plate, and then the punching sleeve moves from the second stop position to the first stop position, so that the waste after punching moves to the bottom of the lower mold together with the punching sleeve and is discharged, thereby overcoming the problem that the waste cannot be discharged when the punching equipment is directly arranged on the lower mold, avoiding the deformation of the mounting hole during the punching and stamping process, and improving the position accuracy of the mounting hole on the vertical cover plate.

[0018] 2. By setting a suction cup in the punching sleeve, the suction cup can absorb the waste material to be punched before the punching sleeve punches the opposing cover plate. Then, when the punching sleeve is reset from the first stop position, the waste material is absorbed by the suction cup. When the waste material passes through the mounting hole of the vertical cover plate, it will not be stuck and unable to be discharged due to the burrs between the waste material and the mounting hole. At the same time, a venting groove and a second air pump are set in the upper mold, so that when the punching sleeve slides into the receiving groove, the second air pump extracts the air in the venting groove. Since the venting groove and the receiving groove are interconnected, it is ensured that the punching sleeve can slide smoothly into the receiving groove. When the punching sleeve leaves the first stop position and resets to the second stop position, the second air pump inflates the venting groove, thereby avoiding high pressure and negative pressure in the receiving groove and avoiding damage to the upper mold due to air pressure changes.

[0019] 3. By setting two sets of limit rods symmetrical about the lower mold on the platform, the limit rods rotate towards each other when limiting the opposing cover plate, thereby completing the automatic limiting of the opposing cover plate before stamping. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figure 1-Figure 5 and Fig.12 : A stamping and forming equipment for an aluminum vertical cover plate, comprising an upper mold 1 and a lower mold 2 arranged from top to bottom in a vertical direction; a receiving groove 11 corresponding to the mounting hole on the vertical cover plate 5 is obliquely arranged at the bottom of the upper mold 1, and a punching sleeve 21 is penetrated and arranged on the lower mold 2 along the extension direction of the receiving groove 11, and the punching sleeve 21 is slidably matched with the lower mold 2, and the punching sleeve 21 has a first stop position and a second stop position when moving. When the punching sleeve 21 is located at the first stop position, the punching sleeve 21 passes through the lower mold 2 and punches the vertical cover plate 5, and the punched waste is pushed into the receiving groove 11 by the upper end of the punching sleeve 21. At this time, the punching sleeve 21 is slidably matched with the receiving groove 11, and when the punching sleeve 21 is located at the second stop position, the upper end of the punching sleeve 21 is located below the lower mold 2, and there is a gap between the punching sleeve 21 and the lower part of the lower mold 2, and the waste is discharged through the gap.

[0035] In the traditional forming process of the vertical cover plate 5, the stamping process uses a stamping device, and the punching process uses a punching device, so the two devices need to be processed separately. In order to improve work efficiency, the stamping process is combined with the punching process. The two processes are completed by one device. There are the following difficulties: First, the punching part of the traditional punching device is mostly set vertically downward. After combining the stamping and punching, the punching device needs to be set in the upper mold 1 of the stamping device. Since the vertical cover plate 5 is a bent structure and the mounting holes are located on the two end faces of the vertical cover plate 5, the upper mold 1 cannot provide enough space for placing the punching device. If the punching device is directly set in the lower mold 2, the waste after punching cannot be discharged.

[0036] In order to avoid the above situation, a punching sleeve 21 for punching the counter cover plate 5 is provided on the lower mold 2, and a first stop position and a second stop position are provided on the punching sleeve 21, so that the waste material can be discharged from the bottom of the lower mold 2 after the punching sleeve 21 completes punching the counter cover plate 5. The specific structure and working process of the molding equipment are as follows: The bottom of the upper mold 1 is a V-shaped structure protruding downward, and a V-shaped groove is provided on the upper part of the lower mold 2. When the upper mold 1 and the lower mold 2 are closed, a V-shaped mold cavity is formed. A hydraulic press is provided on the upper part of the upper mold 1, and the hydraulic press is used to drive the upper mold 1 to rise and fall. The V-shaped mold cavity is used to accommodate the vertical cover plate 5 when the stamping is completed. The vertical cover plate 5 when the stamping is completed is composed of two end faces with an angle, and the angle between the two end faces is the same as the bending angle of the vertical cover plate 5 when it is finally formed. Two groups of receiving grooves 11 corresponding to the two end faces are respectively provided at the bottom of the upper mold 1, and the extension direction of each group of receiving grooves 11 is perpendicular to the end face corresponding to the receiving groove 11, and the receiving groove 11 is in an inclined state. Two groups of punching sleeves 21 corresponding to the two groups of receiving grooves 11 are provided on the lower mold 2, and the punching sleeves 21 pass through the lower mold 2 along the extension direction of the corresponding group of receiving grooves 11 and slide with the lower mold 2. A hydraulic push rod 22 for driving the punching sleeve 21 to move is provided below the punching sleeve 21.

[0037] The punching sleeve 21 has a first stop position and a second stop position when it moves under the drive of the hydraulic push rod 22. The vertical cover plate 5 is first punched and then punched, that is, the plate used to press the vertical cover plate 5 is placed on the lower mold 2. A limiting unit 4 is arranged around the lower mold 2. The limiting unit 4 limits the plate. The specific structure of the limiting unit 4 will be expanded below and will not be described here. Then the upper mold 1 descends to punch the plate on the lower mold 2, so that the plate between the upper mold 1 and the lower mold 2 is punched and formed. At this time, the punching sleeve 21 is located at the second stop position, and the upper end of the punching sleeve 21 is located below the lower mold 2. At this time, the extension direction of the punching sleeve 21 coincides with the extension direction of the receiving groove 11. After the upper mold 1 and the lower mold 2 punch the plate and maintain the pressure to the rated time, the punching sleeve 21 moves from the second stop position to the first stop position under the action of the hydraulic push rod 22. During the movement, the upper part of the punching sleeve 21 first passes through the lower mold 2 from the bottom of the lower mold 2, and then punches the vertical cover plate on the lower mold 2. The end face of the plate 5 is extruded and punched. After the vertical cover plate 5 is punched, the vertical cover plate 5 drives the punched waste to continue to rise, and the vertical cover plate 5 drives the waste to slide into the accommodating groove 11. After the punching sleeve 21 reaches the second stop position, it is immediately reset, that is, the punching sleeve 21 moves from the second stop position to the first stop position. In the process of resetting the punching sleeve 21, the waste located at the upper end of the punching sleeve 21 moves synchronously with the punching sleeve 21. When the punching sleeve 21 moves to the second stop position, the punching sleeve 21 is located below the lower mold 2. At this time, there is a gap between the upper end of the punching sleeve 21 and the lower part of the lower mold 2, and the waste located at the upper end of the punching sleeve 21 is discharged from the gap.

[0038] Since the upper mold 1 and the lower mold 2 are always in a closed state when the punching sleeve 21 punches the opposing cover plate 5, secondary positioning of the opposing cover plate 5 before punching is avoided. Compared with the processing method of punching first and then stamping, only one positioning is required for stamping first and then punching, which improves the punching efficiency. At the same time, the punching sleeve 21 is arranged on the lower mold 2, and a first stop position and a second stop position are set for the punching sleeve 21, so that the punching sleeve 21 moves from the second stop position to the first stop position after the punching of the standing cover plate 5 is completed to complete the punching of the standing cover plate 5, and then the punching sleeve 21 moves from the second stop position to the first stop position, so that the waste material after punching is moved to the bottom of the lower mold 2 together with the punching sleeve 21 and discharged, thereby overcoming the problem that the waste material cannot be discharged when the punching equipment is directly arranged on the lower mold 2.

[0039] Reference Figure 4 A suction cup 211 is arranged inside the punching sleeve 21 and is movable along the extension direction of the punching sleeve 21. The opening end of the suction cup 21 faces the upper end of the punching sleeve 21, and the suction cup 211 absorbs the waste material under punching.

[0040] The suction by the suction cup 211 prevents the punched waste from being stuck during the discharge process with the punching sleeve 21 , and ensures that the waste can be smoothly moved to the second stop position with the punching sleeve 21 for discharge.

[0041] Reference Figure 5 An air filling chamber 213 is fixedly provided at the lower end of the punching sleeve 21, and a pushing plate 212 is slidably provided on the air filling chamber 213 along the extension direction of the punching sleeve 21. The suction cup 211 moves synchronously with the pushing plate 212, and an air filling chamber is formed between the side of the pushing plate 212 away from the punching sleeve 21 and the air filling chamber 213, and a first air pump 214 is provided on one side of the air filling chamber.

[0042] Reference Figure 5 and Figure 7 : A switch valve 215 connected to the suction cup 211 is arranged on the side of the pushing plate 212 away from the suction cup 211. The switch valve 215 is opened only when the punching sleeve 21 is in the second stop position. Before the punching sleeve 21 moves from the second stop position to the first stop position, the switch valve 215 is closed.

[0043] The end of the hydraulic push rod 22 is fixedly connected to the air filling chamber 213, and an extension tube 216 is provided between the suction cup 211 and the push plate 212 along the extension direction of the punching sleeve 21, and the two ends of the extension tube 216 are respectively fixedly connected to the lower end of the suction cup 211 and the push plate 212. The first air pump 214 provided on one side of the air filling chamber can discharge the external air into the air filling chamber, and can also discharge the air in the air filling chamber. After the vertical cover plate 5 is stamped, the punching sleeve 21 starts to move from the second stop position to the first stop position under the action of the hydraulic push rod 22. At this time, the switch valve 215 is closed, and the first air pump 214 inflates the inflation chamber. The push plate 212 pushes the suction cup 211 through the extension tube 216, and the open end of the suction cup 211 extends from the upper end of the punching sleeve 21. Since the push plate 212 is provided with limit stops on both sides when moving along the extension direction of the punching sleeve 21, the push plate 212 pushes the suction cup 211 to extend from the upper end of the punching sleeve 21 for a certain distance and stops moving. The certain distance needs to be set according to actual usage. When the punching sleeve 21 moves toward the first stop position, the suction cup 211 first contacts the vertical cover plate 5, and the suction cup 211 is squeezed as the punching sleeve 21 moves. After the suction cup 21 is squeezed and deformed, the outer circumferential diameter of the open end of the suction cup 211 must be less than or equal to the inner ring diameter of the punching sleeve 21. The squeezed suction cup 211 has an adsorption effect on the vertical cover plate 5. When the punching sleeve 21 continues to move, the punching sleeve 21 punches holes on the vertical cover plate 5, and the punched waste is adsorbed by the suction cup 211. The punching sleeve 21 drives the punched waste to slide into the receiving groove 11 and starts to reset after reaching the first stop position. In the process of resetting to the second stop position, the suction cup 211 drives the waste to pass through the vertical cover plate 5 again. At this time, the mounting hole of the vertical cover plate 5 may hinder the punched waste. After the suction cup 211 is set to adsorb the waste, it can avoid the waste from being stuck when passing through the mounting hole of the vertical cover plate 5, thereby ensuring that the waste can be discharged smoothly. When the punching sleeve 21 moves to the second stop position, the switch valve 215 is opened, the first air pump 214 inflates the inflation cavity, the suction cup 211 is depressurized, and the waste material is separated from the suction cup 211 and discharged through the gap.

[0044] Reference Figure 8 A vent groove 12 is provided in the upper mold 1 and is interconnected with the accommodating groove 11. A second air pump 13 is provided on the vent groove 12 for blowing air into the vent groove 12 when the punching sleeve 21 leaves the first stop position.

[0045] If the vent groove 12 is not provided, after the punching sleeve 21 slides into the receiving groove 11, the inside of the receiving groove 11 loses communication with the outside, resulting in a high pressure in the receiving groove 11 when the punching sleeve 21 slides into the receiving groove 11, and a negative pressure phenomenon occurs in the receiving groove 11 when the punching sleeve 21 leaves the first stop position, which is easy to cause damage to the upper mold 1. After the vent groove 12 and the second air pump 13 are provided, when the punching sleeve 21 slides into the receiving groove 11, the second air pump 13 extracts the air in the vent groove 12. Since the vent groove 12 and the receiving groove 11 are connected to each other, it is ensured that the punching sleeve 21 can slide smoothly into the receiving groove 11. When the punching sleeve 21 leaves the first stop position and resets to the second stop position, the second air pump 13 inflates the vent groove 12, so that the high pressure and negative pressure in the receiving groove 11 can be avoided, and the upper mold 1 can be prevented from being damaged due to air pressure changes.

[0046] Reference Figure 6 and Figure 8 : A platform 3 for supporting the lower mold 2 is arranged around the lower mold 2, and a conveying groove 31 is arranged on the upper part of the platform 3. The width of the conveying groove 31 is the same as the length of the vertical cover plate 5 in the width direction of the platform 3.

[0047] Reference Figure 8 and Fig. 9 : A limiting unit 4 is also provided on the platform 3 for limiting the length of the opposing cover plate 5 in the length direction of the platform 3. The limiting unit 4 includes two groups of limiting rods 41 symmetrically arranged about the lower mold 2. The two groups of limiting rods 41 rotate toward each other when limiting the opposing cover plate 5, and the straight-line distance between the two rotation centers of the two groups of limiting rods 41 is the same as the length of the standing cover plate 5 in the length direction of the platform 3.

[0048] Before stamping the sheet of the opposing cover plate 5, there is no need to place the standing cover plate 5 completely above the lower mold 2, so as to ensure that the staff can maintain a certain distance from the working area of ​​the upper mold 1 and the lower mold 2. When in use, it is only necessary to push the sheet of the standing cover plate 5 between the two groups of limit rods 41, and then the two groups of limit rods 41 begin to rotate towards each other, and the two groups of limit rods 41 that rotate and tilt towards each other limit the sheet of the opposing cover plate 5. Since the straight-line distance between the two rotation center points of the two groups of limit rods 41 is the same as the length of the standing cover plate 5 in the length direction of the platform 3, the mutually inclined limit rods 41 guide the sheet of the opposing cover plate 5, so that the sheet of the standing cover plate 5 slides to the stamping position, thereby completing the limiting of the sheet of the opposing cover plate 5.

[0049] Reference Figure 9-11 : A placement seat 42 hinged to the limiting rod 41 is arranged on the platform 3, and a driving unit 43 for driving the limiting rod 41 to rotate is arranged at one end of the limiting rod 41 facing the lower mold 2.

[0050] The driving unit 43 includes a rotary driver 431, a traction rope 432 and a reel 433. The traction rope 432 is arranged on one end of the limiting rod 41 facing the lower mold 2. The traction rope 432 is wound around the reel 433. The reel 433 is located below the limiting rod 41. The rotary driver 431 is arranged at the end of the reel 433. The rotary driver 431 is preferably a servo motor. The rotary driver 431 reels or releases the traction rope 432 by driving the reel 433 to rotate, so that the limiting rod 41 can rotate.

[0051] Reference Fig. 9 A weight 44 is provided at one end of the limiting rod 41 away from the lower mold 2.

[0052] The weight 44 is used to assist the limit rod 41 in resetting after rotation. The limit rod 41 is in an initial state when it is in a horizontal state. The rotation angle of the limit rod 41 is less than 90 degrees, otherwise the weight 44 will not be able to successfully reset the limit rod 41.

[0053] Reference Figure 1 and Figure 8 : Two groups of rollers 32 are symmetrically arranged on the platform 3 about the lower mold 2, and the axes of the rollers 32 are parallel to the width direction of the platform 3.

[0054] When placing the plate of the vertical cover plate 5, the vertical cover plate 5 before stamping is pushed into the platform 3 from one end along the length direction of the platform 3. The roller 32 on the platform 3 can reduce the friction when the plate slides, and can also prevent the metal debris remaining on the platform 3 from scratching the surface of the plate.

[0055] Working principle: The punching sleeve 21 has a first stop position and a second stop position when it moves under the drive of the hydraulic push rod 22. The vertical cover plate 5 is punched first and then punched, that is, the plate used to press the vertical cover plate 5 is placed on the lower mold 2. A limiting unit 4 is arranged around the lower mold 2, and the limiting unit 4 limits the plate. Then the upper mold 1 descends to punch the plate on the lower mold 2, so that the plate between the upper mold 1 and the lower mold 2 is punched and formed. At this time, the punching sleeve 21 is located at the second stop position, and the upper end of the punching sleeve 21 is located below the lower mold 2. At this time, the extension direction of the punching sleeve 21 coincides with the extension direction of the receiving groove 11. After the upper mold 1 and the lower mold 2 punch the plate and maintain the pressure for the rated time, the punching sleeve 21 moves from the second stop position to the first stop position under the action of the hydraulic push rod 22. During the movement, the upper part of the punching sleeve 21 first passes through the lower mold 2 from the bottom of the lower mold 2, and then punches the vertical cover on the lower mold 2. The end face of the plate 5 is extruded and punched. After the vertical cover plate 5 is punched, the vertical cover plate 5 drives the punched waste to continue to rise, and the vertical cover plate 5 drives the waste to slide into the accommodating groove 11. After the punching sleeve 21 reaches the second stop position, it is immediately reset, that is, the punching sleeve 21 moves from the second stop position to the first stop position. In the process of resetting the punching sleeve 21, the waste located at the upper end of the punching sleeve 21 moves synchronously with the punching sleeve 21. When the punching sleeve 21 moves to the second stop position, the punching sleeve 21 is located below the lower mold 2. At this time, there is a gap between the upper end of the punching sleeve 21 and the lower part of the lower mold 2, and the waste located at the upper end of the punching sleeve 21 is discharged from the gap.

[0056] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
