[0001] The invention relates to the technical field of motor housing processing, and in particular to a stamping device for motor housing processing. Background Art

[0002] The motor housing is an important part of the motor, and its quality and craftsmanship are directly related to the performance and service life of the motor. The stamping production process is an efficient and precise manufacturing method that can quickly and accurately produce steel sheet parts with complex shapes, so it is often used in the manufacturing process of motor housings.

[0003] The patent document with the announcement number CN117718385B discloses a device and a stamping method for processing and stamping of motor end covers, including a mounting plate, a gantry fixed on the top of the mounting plate, a hydraulic cylinder fixed on the top of the gantry, a stamping assembly fixed on the bottom of the hydraulic cylinder by bolts, and a sliding assembly fixedly connected to the top of the gantry; the stamping assembly includes a stamping part, the stamping part includes a mounting cylinder, a conical stamping die is fixed on the bottom of the mounting cylinder, two symmetrical guide ways are fixed on the inner wall of the mounting cylinder, and two symmetrical rectangular connecting holes are opened through the outer wall of the mounting cylinder, and side plates are fixed on the two inner side walls of the two rectangular connecting holes; the sliding assembly includes a positioning part, a first adjusting part slidably matched on the positioning part, a second adjusting part slidably matched on the positioning part, and a pusher slidably matched on the positioning part. The device performs a ejection operation by embedding the motor end cover inside the conical stamping die to remove the stamped motor end cover.

[0004] However, the following problems still exist in this solution. As a complex stamping part, the motor housing needs to be punched during stamping to make mounting holes, heat dissipation holes, etc. When punching holes in the existing motor housing, it is necessary to replace the special punching die after the stamping is completed. Replacing the punching die will affect the punching efficiency, and the motor housing needs to be readjusted and positioned, and the punching accuracy cannot be guaranteed. In addition, when punching holes, due to the uneven force on the motor housing, the motor housing will be deformed near the punching hole during the punching process, and even the punching hole position will be offset, affecting the subsequent assembly or use of the motor housing. Summary of the invention

[0005] The present invention provides a stamping device for processing a motor housing, aiming to solve the problem in the related art that replacement of a punching die affects the punching efficiency and easily causes deformation of a motor cover during punching.

[0006] The stamping equipment for processing the motor housing of the present invention comprises an upper die and a lower die which are assembled on a machine base from top to bottom. The lower die is assembled on the machine base in a horizontal rotation manner. A plurality of stamping grooves are opened circumferentially on the lower die. The rotation of the lower die drives the stamping grooves to rotate to a horizontal loading position and a vertical upward stamping position respectively. A loading assembly for pushing the shell to the loading position is arranged in the machine base; A slide groove is provided on the side wall of the punching groove, a sleeve is axially slidable in the slide groove, an adsorption component connected with the sleeve is provided in the lower die, and a punching component is provided on the upper die; The adsorption component adsorbs the shell at the upper material position onto the lower mold through the sleeve. The sleeve adsorbs the shell and rotates with the lower mold to the stamping position. During stamping, the sleeve moves with the deformation of the shell to be flush with the side wall of the slide groove. After stamping, the punching component punches the position on the shell corresponding to the sleeve.

[0007] The effect is that when loading, the loading component pushes the shell to be processed to the loading position, and then the sleeve adsorbs and fixes the shell on the lower mold under the action of the adsorption component, and then the lower mold rotates to drive the shell to the stamping position, and the upper mold moves to the lower mold to stamp the shell. During stamping, the sleeve maintains an adsorption state on the shell, reducing the phenomenon of shell displacement during stamping and improving the stamping accuracy. At the same time, after the stamping is completed, the stamping surface of the upper mold remains stationary in the stamping groove, and the punching component in the upper mold punches the shell. The shell is clamped by the upper and lower molds during punching, so that the shell can be supported during punching, reducing the phenomenon of shell deformation during punching, and improving the processing accuracy and efficiency of the shell.

[0008] Preferably, a mounting groove is provided in the upper mold, and a through hole connected to the mounting groove is provided on the stamping surface of the upper mold. The punching assembly includes: a push piece 1 assembled in the mounting groove, a punching rod slidably assembled in the through hole, the output end of the push piece 1 cooperates with the punching rod, and the punching rod is flush with the stamping surface during stamping. The push piece 1 drives the punching rod to move into the sleeve to punch the shell.

[0009] The effect is that after the upper die punches the shell, the push piece drives the punching rod to move, and punches the position on the shell corresponding to the sleeve.

[0010] Preferably, a placement groove connected to the slide groove is provided in the lower mold, and the adsorption component includes: a receiving block movably assembled in the placement groove, a negative pressure tube installed in the receiving block, the sleeve is connected to the receiving block, and an intermediate groove connected to the negative pressure tube is provided on the receiving block. The negative pressure tube is connected to the sleeve through the intermediate groove so that the sleeve is in a negative pressure state.

[0011] The effect is that the negative pressure tube is connected to the vacuum pump, so that the negative pressure tube is in a negative pressure state, and the sleeve is also in a negative pressure state through the middle groove, so as to adsorb and fix the shell.

[0012] Preferably, four stamping grooves are provided. When the stamping groove rotates to the bottom of the lower mold, it is in the stripping position. The stripping position corresponds to the stamping position up and down. The sleeve is slidably assembled on the receiving block toward the adjacent sleeve. The sliding directions of the two adjacent sleeves are perpendicular to each other. When stamping the shell, the sleeve at the stamping position drives the sleeve at the stripping position to move synchronously through the receiving block. When the sleeve at the stamping position moves to be flush with the stamping groove, the sleeve at the stripping position moves into the stamping groove to eject the shell in the stripping position from the stamping groove.

[0013] The effect is that when the upper mold moves to punch the shell in the stamping position, the shell is deformed under pressure and drives the sleeve in the stamping position to move. The movement of the sleeve drives the receiving block to move downward. When the receiving block moves downward, it drives the sleeve in the stripping position to move into the stamping groove, and ejects the shell that has been stamped in the stripping position, completing the stripping operation of the stripping position while stamping.

[0014] Preferably, a negative pressure hole connected to the middle groove is opened on the negative pressure tube, and the side surface of the negative pressure tube abuts against the inner wall of the middle groove. When the sleeve rotates to the loading position and the punching position, it is connected to the inside of the negative pressure tube through the negative pressure hole.

[0015] The effect is that the negative pressure tube puts only the sleeve at the loading position and the punching position in a negative pressure state through the negative pressure hole, so as to adsorb the shell during loading and fix the shell during punching, thereby reducing the phenomenon of shell displacement during punching.

[0016] Preferably, a limit frame is provided on the machine base, a limit groove is provided on the limit frame, a limit block is slidably assembled up and down in the limit groove, a clearance hole is coaxially provided on the lower mold, a connecting rod is provided on the negative pressure tube, the connecting rod passes through the receiving block and the clearance hole in sequence and is fixedly connected to the limit block, and the connecting rod is spaced apart from the inner wall of the clearance hole.

[0017] The effect is that the limit block slides in the limit groove, so that the receiving block can only slide up and down when it is rotated to any position. At the same time, when the receiving block rotates with the lower mold, the negative pressure tube does not rotate, so that the sleeves in the loading position and the stamping position are always in a negative pressure state. After the stamping is completed, the sleeve is disconnected from the negative pressure tube so that the shell after stamping can be taken out later.

[0018] Preferably, a stopper and an elastic member are provided on the side wall of the sleeve. The stopper is slidably arranged along a sliding direction perpendicular to the sliding direction of the sleeve. A stopper groove is provided on the inner wall of the slide groove. The elastic member is connected to the stopper to drive the stopper to move toward the slide groove. After the sleeve pushes out the shell at the stripping position, the stopper moves to the stopper groove and engages with the stopper groove.

[0019] The effect is that after stripping, the sleeve drives the stopper to move to the stop groove, and the stopper moves into the stop groove and engages with the stop groove under the action of the elastic member 1, thereby fixing the sleeve and reducing the sliding deviation of the sleeve.

[0020] Preferably, an assembly groove is opened in the machine base, and the loading component includes a push piece 2, an elastic piece 2 and a push plate. The output end of the push piece 2 is arranged in the direction of the loading position, and the push plate is slidably arranged in the assembly groove. The elastic piece 2 is connected to the push plate and is used to drive the shell to move to the output end of the push piece 2 through the push plate. The push piece 2 is used to push the shell at the push plate to the loading position.

[0021] The effect is that the second elastic member drives the shell to move to the second push member through the push plate, the second push member drives the shell to move to the loading position, and then the sleeve absorbs the shell for subsequent loading.

[0022] Preferably, the upper mold is rotatably arranged on the machine base, and an intermediate sleeve is coaxially arranged in the placement groove, the intermediate sleeve is fixedly connected to the machine base, and multiple stamping surfaces are circumferentially arranged on the upper mold, and a punching rod is arranged on each stamping surface. Push piece 1 is arranged in the intermediate sleeve, and when the punching rod is rotated to face the lower mold, it corresponds to the output end of push piece 1. A reset piece is arranged in the through hole, and the reset piece is connected to the punching rod to drive the punching end of the punching rod to be flush with the stamping surface.

[0023] The effect is that different stamping surfaces can be replaced according to different stamping needs. When the upper mold rotates, the different stamping surfaces are driven to rotate to correspond to the lower mold. At the same time, the corresponding punching rods are moved to correspond to the output end of the push piece 1, so that the push piece 1 drives the corresponding punching rods to move and punch the shell.

[0024] Preferably, a locking hole is formed on the middle sleeve, and the output end of the push piece one passes through the locking hole and abuts against the punching rod. The output end of the push piece one is provided with a locking groove that is engaged with the end of the punching rod. When the punching rod rotates to a position of the push piece, the reset piece drives the punching rod to engage with the locking groove, which is used to limit the upper mold.

[0025] The effect is that after the upper mold is rotated and adjusted, the output end of the push piece 1 passes through the clamping hole, and the punching rod is engaged with the output end of the push piece 1 under the action of the reset piece, thereby realizing the positioning of the upper mold and reducing the phenomenon of the upper mold rotating when punching the shell.

[0026] Beneficial effects: The present invention fixes the shell by keeping the sleeve adsorbed on the shell during stamping, thereby reducing the phenomenon of shell deviation during stamping. At the same time, after the stamping is completed, the upper mold is stationary, and the shell is clamped between the upper mold and the lower mold. Then, the push piece drives the punching rod to punch the shell. The shell is clamped by the upper mold and the lower mold, thereby reducing the phenomenon of deformation of other positions of the shell during punching, thereby improving the stamping and punching accuracy.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 9As shown, the stamping equipment for processing the motor housing of the present invention comprises a machine base 1, a stamping assembly, a feeding assembly 2, an adsorption assembly 3, and a punching assembly 4. The stamping assembly comprises an upper die 5 and a lower die 6 which are assembled on the machine base 1 from top to bottom. The lower die 6 is arranged below the upper die 5, and the upper die 5 is assembled on the machine base 1 by sliding up and down. The feeding assembly 2 is used to push the housing to be processed to the lower die 6, the adsorption assembly 3 is arranged on the lower die 6, the adsorption assembly 3 adsorbs the housing on the lower die 6, and then the housing is stamped and formed by the upper die 5, and then the punching assembly 4 performs a punching operation on the formed housing.

[0039] Reference Figure 2 and Figure 3 The lower mold 6 is horizontally rotated and assembled on the machine base 1, that is, the rotation axis of the lower mold 6 is arranged in the horizontal direction, and a driving member 11 is arranged on the machine base 1. The driving member 11 is arranged as a motor, and the output shaft of the motor is coaxially connected with the lower mold 6 to drive the lower mold 6 to rotate. A plurality of punching grooves 61 are opened circumferentially on the lower mold 6, and the feeding assembly 2 is arranged on one side of the lower mold 6. As the lower mold 6 rotates, the punching grooves 61 are driven to rotate to the specified position.

[0040] Reference Figure 3 Specifically, when the lower mold 6 drives the stamping groove 61 to rotate to a horizontal position and corresponds to the loading component 2, the stamping groove 61 is in the loading position 01; the lower mold 6 continues to rotate to drive the stamping groove 61 to rotate vertically upward, that is, when the stamping groove 61 rotates to correspond to the upper mold 5, the stamping groove 61 is in the stamping position 02; when the lower mold 6 drives the stamping groove 61 to rotate to the bottom, the stamping groove 61 is in the unloading position 03.

[0041] The pushing assembly pushes the shell to the loading position 01, the adsorption assembly 3 adsorbs the shell on the lower mold 6, the driving part 11 drives the lower mold 6 to rotate, drives the shell to rotate to the stamping position 02, and then the upper mold 5 and the punching assembly 4 stamp and punch the shell, and then the driving part 11 drives the lower mold 6 to continue to rotate, drives the processed shell to rotate to the stripping position 03, and performs the stripping operation to separate the shell from the stamping groove 61.

[0042] Reference Figure 3 and Figure 4 A slide groove 62 is opened on the side wall of the stamping groove 61, and the slide groove 62 is set in the direction of the axis of the lower mold 6. A sleeve 7 is axially slidably arranged in the slide groove 62. Multiple sleeves 7 are arranged corresponding to multiple stamping grooves 61. The sleeve 7 is connected to the adsorption component 3, and the adsorption component 3 adsorbs the shell through the sleeve 7.

[0043] At the loading position 01, the sleeve 7 absorbs the shell to drive the shell to rotate with the lower mold 6. During stamping, the sleeve 7 is driven to move as the shell is deformed. After the stamping is completed, the end of the sleeve 7 moves to be flush with the side wall of the stamping groove 61, that is, the sleeve 7 is in a retracted state at this time, and then the punching assembly 4 punches the position on the shell corresponding to the sleeve 7.

[0044] Reference Figure 3 and Figure 4 A placement groove 63 is provided in the lower mold 6, and the placement groove 63 is connected to the slide groove 62. The adsorption component 3 includes a receiving block 31 and a negative pressure pipe 32. The receiving block 31 is movably assembled in the placement groove 63. An intermediate groove 311 is provided in the receiving block 31. The negative pressure pipe 32 is arranged in the receiving block 31, and the negative pressure pipe 32 is connected to the intermediate groove 311. The negative pressure pipe 32 is connected to the vacuum pump, so that the inside of the negative pressure pipe 32 is in a negative pressure state. The sleeve 7 is connected to the receiving block 31, and the sleeve 7 is connected to the intermediate groove 311, that is, the negative pressure pipe 32 is connected to the sleeve 7 through the intermediate groove 311.

[0045] The negative pressure tube 32 makes the sleeve 7 in a negative pressure state through the middle groove 311 to adsorb the shell, so that the shell can rotate to the stamping position 02 with the lower mold 6. At the same time, during stamping, the shell is fixed to reduce the phenomenon of shell deviation.

[0046] Reference Figure 3 , Figure 4 , Figure 5 , four punching grooves 61 are provided, the sleeve 7 and the receiving block 31 are slidably matched, and the sleeve 7 slides in the direction toward the adjacent sleeve 7, that is, the sliding directions of the two adjacent sleeves 7 are perpendicular to each other. When the upper mold 5 punches the shell, it drives the sleeve 7 to move, and the movement of the sleeve 7 drives the receiving block 31 to move toward the stripping position 03. At the same time, the receiving block 31 drives the sleeve 7 in the stripping position 03 to move into the punching groove 61, and pushes out the shell in the stripping position 03, and removes the shell after punching. At the same time, when the receiving block 31 moves, the receiving block 31 moves relative to the sleeve 7 of the loading position 01, reducing the phenomenon that the sleeve 7 of the loading position 01 interferes with the movement of the receiving block 31.

[0047] Reference Figures 3 to 6, the side of the negative pressure tube 32 abuts against the inner wall of the middle groove 311, that is, when the negative pressure tube 32 rotates, the side of the negative pressure tube 32 maintains an abutting state with the inner wall of the middle groove 311. A negative pressure hole 321 is provided on the negative pressure tube 32, and the interior of the middle tube is connected to the middle groove 311 through the negative pressure hole 321, and the negative pressure hole 321 is respectively connected to the sleeves 7 in the loading position 01 and the punching position 02. When the lower mold 6 rotates, the negative pressure tube 32 is relatively stationary, so that when the lower mold 6 rotates, the negative pressure tube 32 is always connected to the sleeves 7 in the loading position 01 and the punching position 02, so that the sleeves 7 in the loading position 01 and the punching position 02 are in a negative pressure state, and the shell is adsorbed for loading and punching positioning. At the same time, the sleeve 7 in the stripping position 03 is released from the negative pressure state, so that the shell in the stripping position 03 can be moved out.

[0048] Reference Figure 5 and Figure 6 A limit frame 8 is provided on the machine base 1, a limit groove 81 is provided on the limit frame 8, a limit block 82 is provided in the limit groove 81 for sliding up and down, a clearance hole 64 is opened on the lower mold 6, and a connecting rod 322 is provided on the negative pressure tube 32. The connecting rod 322 passes through the receiving block 31 and the clearance hole 64 in turn and is connected to the limit block 82. The connecting rod 322 is fixedly connected to the limit block 82, and the connecting rod 322 is spaced apart from the inner wall of the clearance hole 64.

[0049] When the lower mold 6 rotates, the negative pressure tube 32 is kept stationary relative to the lower mold 6 by the stop block 82 and the connecting rod 322, that is, when the lower mold 6 rotates, the negative pressure tube 32 is stationary. In addition, during stamping, the negative pressure tube 32 can move with the receiving block 31, and the stop block 82 slides in the stop groove 81, reducing the phenomenon that the negative pressure tube 32 interferes with the movement of the receiving block 31. In addition, the connecting rod 322 is spaced apart from the inner wall of the clearance hole 64, so that when the lower mold 6 rotates, the connecting rod 322 moves in the clearance hole 64, and when the connecting rod 322 and the lower mold 6 are not coaxial, the lower mold 6 can still rotate to a different position of the punching groove 61, reducing the phenomenon that the clearance hole 64 interferes with the rotation of the lower mold 6.

[0050] Reference Figure 6 The connecting rod 322 is set to a hollow structure, and the connecting rod 322 is connected to the inside of the negative pressure tube 32. The negative pressure tube 32 is connected to the air pump through the connecting rod 322, so that the negative pressure tube 32 is in a negative pressure state.

[0051] Reference Figure 3 and Figure 4A stopper 71 and an elastic member 72 are provided on the side wall of the sleeve 7. The stopper 71 slides on the sleeve 7, and its sliding direction is perpendicular to the sliding direction of the sleeve 7. The elastic member 72 is provided as a spring. The elastic member 72 is connected to the stopper 71 and the sleeve 7 respectively, and the elastic member 72 is used to drive the stopper 71 to slide in a direction away from the sleeve 7. A stopper groove 621 matching with the stopper 71 is provided on the inner wall of the slide groove 62.

[0052] When the sleeve 7 moves to eject the shell in the unloading position 03, it drives the stop block 71 to move synchronously. After the shell is separated from the stamping groove 61, the stop block 71 moves to the stop groove 621, and the stop block 71 is engaged with the stop groove 621 under the action of the elastic member 72 to fix the sleeve 7. At this time, the end of the sleeve 7 is flush with the surface of the lower mold 6 to reduce the sliding deviation of the sleeve 7 when the lower mold 6 rotates. At the same time, when it rotates to the loading position 01, the sleeve 7 can adsorb the shell.

[0053] Since during stamping, the sliding directions of the sleeves 7 at the stamping position 02 and the stripping position 03 are the same, that is, the movement of the two relative sleeves 7 is the same, in this embodiment, only a stopper 71 and a spring 72 are provided on two adjacent sleeves 7 to achieve the limitation of the sleeve 7.

[0054] Reference Figure 4 In addition, one end of the stopper 71 inserted into the stopper groove 621 is semicircular, so that when the sleeve 7 moves, the stopper 71 can be separated from the stopper groove 621 under the action of its semicircular end.

[0055] Reference Figure 7 and Figure 8 The upper mold 5 is provided with a mounting groove 51, and a through hole 52 is provided on the stamping surface 53 of the upper mold 5, and the through hole 52 is connected with the mounting groove 51.

[0056] Reference Figure 7 and Figure 8 When the upper die 5 moves to punch the shell, the end of the punching rod 42 is flush with the punching surface 53. After punching, the upper die 5 stops moving, and the push piece 41 drives the punching rod 42 to move into the sleeve 7, and punches the shell at the same time. When punching, the shell is clamped between the upper die 5 and the lower die 6, which reduces the deformation of other positions on the shell during punching and improves the punching accuracy.

[0057] Reference Figure 1 and Figure 2The upper mold 5 is rotatably arranged on the machine base 1. The machine base 1 includes a mounting frame 13 that moves up and down. The upper mold 5 is rotatably installed on the mounting frame 13. A driving member 12 is arranged on the mounting frame 13. The output end of the driving member 12 is connected to the upper mold 5. The driving member 12 is set as a motor. The rotating shaft of the upper mold 5 is flush with the rotating shaft of the lower mold 6. A plurality of stamping surfaces 53 are circumferentially arranged on the upper mold 5. In addition, the plurality of stamping surfaces 53 can be set to different shapes according to processing requirements to meet different processing requirements for the shell.

[0058] Reference Figure 7 and Figure 8 , an intermediate sleeve 9 is coaxially arranged in the placement groove 63, and the intermediate sleeve 9 is fixedly connected to the mounting frame 13, that is, the intermediate sleeve 9 is fixedly connected to the mounting frame 13. The push piece 41 is arranged in the intermediate sleeve 9, and the push piece 41 is fixedly connected to the mounting frame 13, that is, when the upper mold 5 rotates, the push piece 41 and the intermediate sleeve 9 are both stationary. A punching rod 42 is arranged on each stamping surface 53, and a reset member 54 is arranged in the through hole 52. The reset member 54 is set as a spring, and the spring is connected to the punching rod 42. The reset member 54 is used to drive the end of the punching rod 42 to move flush with the stamping surface 53. When the stamping surface 53 is replaced, when the corresponding punching rod 42 rotates to correspond to the lower mold 6, corresponding to the output end of the push piece 41, the push piece 41 can drive the corresponding punching rod 42 to move to perform a punching operation on the shell.

[0059] Reference Figure 7 and Figure 8 A card hole 91 is formed on the middle sleeve 9, and the output end of the push piece 41 passes through the card hole 91 and cooperates with the punching rod 42. A card slot 411 is formed on the output end of the push piece 41, and the card slot 411 is buckled with the end of the punching rod 42.

[0060] When the punching rod 42 rotates to correspond to the push piece 41, the output end of the push piece 41 passes through the clamping hole 91 and moves to the outside of the intermediate sleeve 9. At the same time, the punching rod 42 is engaged with the clamping groove 411 under the action of the reset piece 54 to complete the positioning of the upper mold 5, reduce the phenomenon of self-rotation of the upper mold 5 during stamping, and improve the stability during stamping.

[0061] Reference Fig. 9, an assembly groove 14 is provided in the machine base 1, and the feeding assembly 2 includes a push piece 21, an elastic piece 22 and a push plate 23.

The sliding direction of the push plate 23 is perpendicular to the pushing direction of the output end of the push piece 21. A plurality of shells are placed on the side of the push plate 23 away from the elastic piece 22. The elastic piece 22 drives the shell to move to the push piece 21 through the push plate 23, and the output end of the push piece 21 pushes the shell to move to the feeding position 01, so that the sleeve 7 can adsorb the shell for feeding.

[0062] Reference Figure 2 and Fig. 9 A slot 65 is provided on the side of the lower mold 6. The slot 65 is arranged on the side of the lower mold 6 close to the pusher 21. When the pusher 21 pushes the shell to the material loading position 01, the lower mold 6 drives the shell of the material loading position 01 to rotate to the punching position 02. The pusher 21 pushes the new shell to be processed to the material loading position 01. At the same time, the output shaft of the pusher 21 is inserted into the slot 65 to fix the lower mold 6. The lower mold 6 is limited during punching to improve the stability of the lower mold 6.

[0063] The implementation principle of the present invention is as follows: the push piece 21 pushes the shell to move to the loading position 01, and then the negative pressure tube 32 adsorbs the shell through the sleeve 7 to fix the shell on the lower mold 6. The lower mold 6 rotates to drive the shell to rotate to the stamping position 02, and the upper mold 5 moves to stamp the shell. During stamping, the sleeve 7 and the shell maintain an adsorption state to reduce the shell offset phenomenon. After the stamping is completed, the push piece 41 drives the punching rod 42 to move to punch the shell. During punching, the upper mold 5 and the lower mold 6 clamp and maintain the clamping state of the shell to reduce the deformation of other positions of the shell during punching, thereby reducing the offset of the punching position and improving the punching accuracy and punching efficiency.

[0064] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
