Detailed Description

The present invention will be described in detail below with reference to the embodiments shown in the drawings, but it should be understood that the embodiments are not limited to the present invention, and functional, method, or structural equivalents and alternatives according to the embodiments are within the scope of protection of the present invention by those skilled in the art.

Referring to fig. 1-9, in one embodiment of a computer case stamping apparatus 100 of the present invention, the computer case stamping apparatus 100 may be used for stamping a workpiece 50, and the stamped workpiece 50 may be assembled to form a computer case.

The computer case press apparatus 100 includes a press mechanism 10 and a material transfer mechanism 20 that transfers a workpiece 50, and the press mechanism 10 includes a table 12 and a press machine 11 that presses the workpiece 50 on the table 12. The worktable 12 is internally provided with a material fixing mechanism 13, and the material fixing mechanism 13 comprises a fixing component 131 and a driving component 132 for driving the fixing component 131 to prop against or loosen the workpiece 50. The fixed assembly 131 includes a fixed rod 1311, a movable rod 1312, and a fixed segment 1313. The fixing section 1313 and the workpiece 50 form the abutting surface 130 by longitudinally moving downwards the driving assembly 132, so that the workpiece 50 is abutted against the workbench 12 to fix the workpiece 50, the position of the workpiece 50 is kept fixed when the punching machine 11 punches the workpiece 50, the stability of the workpiece 50 is improved, the punching machine 11 can accurately punch the workpiece 50, the punched workpiece 50 can be assembled into a computer shell (not shown), and the problem that the punching machine 11 cannot accurately punch the workpiece 50 due to the position deviation of the workpiece 50 when the punching machine 11 punches the workpiece 50 is avoided.

Specifically, the material fixing mechanism 13 includes a fixing component 131, and a driving component 132 for driving the fixing component 131 to abut against or loosen the workpiece 50; the fixed assembly 131 includes a fixed rod 1311 formed opposite to each other and slidably connected to the driving assembly 132, a movable rod 1312 hingedly connected to the fixed rod 1311 through a hinge 1314, and a fixed section 1313 formed at an end of the movable rod 1312 remote from the fixed rod 1311; the fixed segment 1313 forms an abutment surface 130 with the workpiece 50 to abut the workpiece 50 against the table 12. The fixing section 1313 forms an abutting surface 130 with the workpiece 50 to fix the workpiece 50 on the workbench 12, so that when the punch 11 punches the workpiece 50, the position of the workpiece 50 is not shifted, and accurate punching of the workpiece 50 by the punch 11 is realized.

It should be noted that the hinge portion 1314 can movably adjust the fixed lever 1311 and the movable lever 1312 to rotate along the hinge portion 1314, thereby achieving the holding and releasing of the workpiece 50. The first moving member 1322 and the second moving member 1323 drive the fixed rod 1311 to slide along the end surface of the first moving member 1322 or back to each other, so as to drive the movable rod 1312 to rotate, thereby realizing the supporting and releasing of the fixed segment 1313 on the workpiece 50. The chassis 121 is used for supporting the workpiece 50 on the table 12, and the chassis 121 can further define the position of the workpiece 50, so as to achieve accurate stamping of the workpiece 50 by the stamping machine 11. The guide rod 111 drives the punching plate 112 to move longitudinally, so that the punching machine 11 punches the workpiece 50 located on the chassis 121. The transfer mechanism 20 is responsible for transferring the workpiece 50 between the press mechanisms 10. The extracting mechanism 40 is capable of sucking the workpiece 50 from the extracting frame 30 and transferring the workpiece 50 to the punching mechanism 10 or sucking the workpiece 50 from the punching mechanism 10 and transferring the workpiece 50 to the extracting frame 30 while completing the cleaning work of the workpiece 50.

Referring to fig. 1, the computer case stamping apparatus 100 includes a stamping mechanism 10 and a material transferring mechanism 20, wherein the stamping mechanism 10 is responsible for precisely stamping a workpiece 50, and the material transferring mechanism 20 is used for transferring the workpiece 50 from the stamping mechanism 10a to another stamping mechanism 10b. The computer case stamping apparatus 100 may include a plurality of stamping mechanisms 10 to achieve accurate stamping of different locations of the workpiece 50. The press mechanism 10 includes a table 12, a press 11 for pressing a workpiece 50 on the table 12, and the press 11 and the table 12 are connected by a boom 14. The press 11 includes a hydraulic cylinder 113, a guide rod 111, and a press plate 112, the hydraulic cylinder 113 being capable of driving the guide rod 111 to move longitudinally (i.e., in the direction a or the direction B), the end of the guide rod 111 facing the table 12 forming the press plate 112. The longitudinal downward movement (i.e., movement in direction B) of the guide bar 111 drives the pressing plate 112 to move longitudinally downward (i.e., movement in direction B), thereby effecting pressing of the workpiece 50 on the table 12. In the present embodiment, the hydraulic cylinder 113 drives the guide rod 111 to move longitudinally, and the guide rod 111 may be moved longitudinally by other driving means, so long as the guide rod 111 can move longitudinally and the pressing plate 112 can press the workpiece 50.

Referring to fig. 2, the table 12 includes a material fixing mechanism 13 and a chassis 121 formed on a surface of the table 12. The material fixing mechanism 13 can press the workpiece 50 in the chassis 121 against the chassis 121, thereby improving the stability of the workpiece 50 and avoiding the position deviation of the workpiece 50 when the punch 11 punches the workpiece 50. The chassis 121 can support the workpiece 50 on the workbench 12, and the chassis 121 has a limiting function, so that the workpiece 50 can be ensured to face the stamping disc 112, meanwhile, the chassis 121 provides a positioning function for the material moving mechanism 20, the material taking mechanism 40 sucks the workpiece 50 from the chassis 121, so that the material moving mechanism 20 can accurately suck the workpiece 50 in the chassis 121 by the material taking mechanism 40. The shape of the chassis 121 is not particularly limited in this embodiment, as long as the workpiece 50 can be accommodated in the chassis 121 and the fixing section 1313 can form the abutment surface 130 with the workpiece 50, and the shape of the chassis 121 can be adaptively adjusted according to the shape of the workpiece 50. The hinge 1314 is circumferentially fixed about the chassis 121 such that the movable rod 1312 and the fixed segment 1313, which are connected by the hinge 1314, provide for the abutment of the workpiece 50 within the chassis 121. Moreover, the hinge portion 1314 is circumferentially fixed around the chassis 121, so that the fixing segments 1313 are also circumferentially distributed along the chassis 121, and the fixing segments 1313 circumferentially abut against the workpiece 50 in the chassis 121, thereby further improving the stability of the workpiece 50 and avoiding the position of the workpiece 50 from being deviated. The movable rod 1312 and the fixed segment 1313 each extend toward the chassis 121, so that the movable rod 1312 and the fixed segment 1313 can be secured to rotate along the hinge 1314, such that the fixed segment 1313 forms an abutment surface 130 with the workpiece 50. The chassis 121, the movable rod 1312 and the fixed section 1313 together enclose an accommodating space 1310 for accommodating the workpiece 50, so as to accommodate the workpiece 50 in the accommodating space 1310, thereby facilitating the fixed section 1313 to abut against the workpiece 50.

Referring to fig. 3 to 6, the material fixing mechanism 13 can further fix the workpiece 50 on the chassis 121, so as to improve the stability of the workpiece 50, so as to avoid the problem that the punch 11 cannot accurately punch the workpiece 50 due to the position deviation of the workpiece 50 in the process of punching the workpiece 50 by the punch 11. The material fixing mechanism 13 includes a fixing component 131 and a driving component 132 for driving the fixing component 131 to abut against or loosen the workpiece 50. The fixing component 131 and the workpiece 50 form an abutting surface 130 to abut the workpiece 50 on the chassis 121, so that the workpiece 50 is prevented from being shifted in position in the stamping process, and the workpiece 50 is precisely stamped by the stamping disc 112.

The fixed assembly 131 includes a fixed rod 1311 formed opposite to and slidably connected to the driving assembly 132, a movable rod 1312 hingedly connected to the fixed rod 1311 through a hinge 1314, and a fixed section 1313 formed at an end of the movable rod 1312 remote from the fixed rod 1311. The fixing rod 1311 is used for connecting the fixing component 131 and the driving component 132, and further drives the fixing component 131 to support and release the workpiece 50 through the driving component 132. The free end of the fixed rod 1311 is slidably connected to the end surface of the first moving member 1322 away from the driving member 1321, and the second moving member 1323 is always kept in a fitting state with the fixed rod 1311 during the longitudinal movement. When the driving member 1321 moves longitudinally, the driving member 1321 drives the second moving member 1323 to move longitudinally, and since the end portion of the fixed rod 1311 away from the free end is fixed around the chassis 121 by the hinge portion 1314, the free end of the fixed rod 1311 slides along the end surface of the first moving rod away from the driving member 1321, and the sliding of the free end of the fixed rod 1311 drives the movable rod 1312 hinged to the fixed rod 1311 to rotate along the axis P of the hinge portion 1314a or the axis Q of the hinge portion 1314b, so as to achieve the supporting and releasing of the fixed segment 1313 on the workpiece 50.

As will be appreciated by those skilled in the art, since the fixed lever 1311 is disposed opposite to each other, the hinge portion 1314 connected to the fixed lever 1311, the movable lever 1312 and the fixed section 1313 are disposed opposite to each other, so that the axis P of the hinge portion 1314a connected to the movable lever 1312a and the axis Q of the hinge portion 1314b connected to the movable lever 1312b are parallel, and the movable lever 1312a rotates along the axis P of the hinge portion 1314a, and the movable lever 1312b rotates along the axis Q of the hinge portion 1314 b.

It should be noted that, the sliding of the free end of the fixed rod 1311 toward the end surface of the first moving member 1322 away from the driving member 1321 according to the present embodiment means that the free end of the fixed rod 1311a slides along the direction G, and the free end of the fixed rod 1311b slides along the direction H, that is, the acute included angle (i.e., the included angle α) formed by the fixed rod 1311 and the end surface of the first moving member 1322 away from the driving member 1321 decreases with the sliding of the free end of the fixed rod 1311 toward each other; the sliding of the free end of the fixed rod 1311 away from the driving member 1321 along the end surface of the first moving member 1322 refers to the sliding of the free end of the fixed rod 1311a along the direction H, and the sliding of the free end of the fixed rod 1311b along the direction G, that is, the acute included angle (i.e., included angle α) formed by the fixed rod 1311 and the end surface of the first moving member 1322 away from the driving member 1321 increases with the sliding of the free end of the fixed rod 1311 away from the driving member 1321.

The movable rod 1312 is used for controlling the holding and releasing of the fixed segment 1313 against the workpiece 50. When the free end of the movable lever slides along the end surface of the first movable lever away from the driving member 1321, the movable lever 1312 rotates about the axis P (or the axis Q) on which the hinge 1314 is located. When the movable rod 1312a drives the fixed segment 1313a to rotate in the direction C and the movable rod 1312b drives the fixed segment 1313b to rotate in the direction D, the fixed segment 1313a and the fixed segment 1313b do not form the abutting surface 130 with the workpiece 50, i.e. the fixed segment 1313 loosens the workpiece 50, and at this time, the material moving mechanism 20 can adsorb the workpiece 50 and move the workpiece 50 through the first adsorption assembly 21. When the movable rod 1312a drives the fixed segment 1313a to rotate in the direction E and the movable rod 1312b drives the fixed segment 1313b to rotate in the direction F, the fixed segment 1313a and the fixed segment 1313b form a holding surface 130 with the workpiece 50, that is, the fixed segment 1313 holds the workpiece 50 against the chassis 121, and at this time, the punching machine 11 can precisely punch the workpiece 50. Preferably, the movable bar 1312 forms a turn 1315, and the turn 1315 can increase the volume of the receiving space 1310, thus accommodating workpieces 50 of different sizes or different shapes. At the same time, the turning portion 1315 can enlarge the abutting surface 130 of the fixing section 1313 and the workpiece 50, thereby improving the stability of the workpiece 50 and avoiding the workpiece 50 from being displaced during the stamping process.

The fixed section 1313 is used to control the holding and releasing of the workpiece 50. When the fixing section 1313 and the workpiece 50 form the abutting surface 130, the workpiece 50 can be abutted on the chassis 121 and the position of the workpiece is not deviated in the stamping process; when the fixed segment 1313 does not form the abutment surface 130 with the workpiece 50, the workpiece 50 is in a relaxed state, and the position of the workpiece 50 may be moved.

In the present embodiment, the fixing section 1313 is rectangular in the top view direction, and the fixing section 1313 may be circular, trapezoidal, or other shape in the top view direction, and the shape of the fixing section 1313 in the top view direction is not particularly limited in the present embodiment, as long as the shape that forms the abutting surface 130 with the workpiece 50 and does not affect the pressing of the workpiece 50 by the pressing machine 11 can be satisfied. Because the fixed bars 1311 are disposed opposite to each other, and the number of the fixed bars 1311 matches the number of the movable bars 1312 and the number of the fixed segments 1313, the fixed segments 1313 are disposed opposite to each other, and the holding surfaces 130 formed by the fixed segments 1313 and the workpiece 50 are disposed opposite to each other, so that the force generated by the fixed segments 1313 on the workpiece 50 when the fixed segments 1313 hold the workpiece 50 on the chassis 121 is symmetrical, thereby improving the stability of the workpiece 50. Preferably, the fixing section 1313 may be formed in plurality along the chassis 121 in opposite directions, thereby increasing the area of the abutting surface 130 of the fixing section 1313 and the chassis 121 and further improving the stability of the workpiece 50.

The driving component 132 is used for driving the fixing component 131 to rotate so as to realize the supporting and releasing of the workpiece 50. The driving unit 132 includes a driving member 1321 for driving the driving unit 132 to move longitudinally, a first moving member 1322 fixedly connected to the driving member 1321, a second moving member 1323 for maintaining a contact state with the fixed rod 1311, and a connecting member 1324 for connecting the first moving member 1322 and the second moving member 1323. The driving member 1321 (e.g., a cylinder) longitudinally moves the first moving member 1322 and the second moving member 1323 by driving the free end of the fixed rod 1311 to slide along the end surface of the first moving member 1322 away from the driving member 1321, so that the movable rod 1312 and the fixed segment 1313 rotate along the hinge 1314, thereby achieving the holding and releasing of the workpiece 50. The first moving member 1322 is fixedly connected to the driving member 1321, so that the first moving member 1322 is driven to move longitudinally by the longitudinal movement of the driving member 1321. The second movable member 1323 is always attached to the fixed rod 1311 during the longitudinal movement, so that the fixed rod 1311 and the first movable member 1322 can be kept in sliding connection, and separation of the fixed rod 1311 and the first movable member 1322 during the longitudinal movement of the first movable member 1322 is avoided, and meanwhile, the second movable member 1323 can fix the fixed rod 1311, so that the free end of the fixed rod 1311 slides along the end surface of the first movable member 1322 away from the driving member 1321 and cannot be separated from the first movable member 1322. When the driving member 1321 is stationary, the second moving member 1323 can connect the fixed rod 1311 with the first moving member 1322 and cannot slide, so that the problem that the fixed segment 1313 cannot support the workpiece 50 due to the rotation of the movable rod 1312 and the fixed segment 1313 caused by the sliding of the fixed rod 1311 is avoided.

When the driving member 1321 moves longitudinally upward (i.e., moves upward in the direction a), the driving member 1321 drives the first moving member 1322 to move longitudinally upward, and thus the second moving member 1323 connected to the first moving member 1322 via the connecting member 1324 moves longitudinally upward, at this time, the free end of the fixed lever 1311 slides along the end face of the first moving member 1322 away from the driving member 1321, so that the movable lever 1312a and the fixed segment 1313a rotate in the direction C with the axis P of the hinge portion 1314a, and the movable lever 1312b and the fixed segment 1313b rotate in the direction D with the axis Q of the hinge portion 1314b, whereby the fixed segment 1313 loosens the workpiece 50; when the driving member 1321 moves longitudinally downward (i.e., moves in the direction B), the driving member 1321 drives the first moving member 1322 to move longitudinally downward, and thus the second moving member 1323 connected to the first moving member 1322 via the connecting member 1324 moves longitudinally downward, at this time, the free end of the fixed rod 1311 slides away from the end surface of the driving member 1321 along the first moving member 1322, so that the movable rod 1312a and the fixed segment 1313a rotate in the direction E along the axis P where the hinge portion 1314a is located, and then the movable rod 1312B and the fixed segment 1313B rotate in the direction F along the axis Q where the hinge portion 1314B is located, whereby the fixed segment 1313 holds the workpiece 50 against the chassis 121.

Referring to fig. 7 and 8, the material moving mechanism 20 includes a first adsorption assembly 21, a first link 27, a second link 28, a third link 22, a fixed block 29, a translation block 26, a gear set 24, and a chute 25, and the gear set 24 includes a first gear 241 and a second gear 242. The first adsorption component 21 is formed at the end part of the third connecting rod 22 and is connected with the translation block 26 through the third connecting rod 22, a motor 23 and a first gear 241 are arranged at the top of the translation block 26, a second gear 242 meshed with the first gear 241 is formed on the side wall of the translation block 26 far away from the third connecting rod 22, the second gear 242 is fixedly connected with the first connecting rod 27, the second connecting rod 28 is rotationally connected with the first connecting rod 27, the end part of the second connecting rod 28, which is not connected with the first connecting rod 27, is connected with the fixed block 29, the sliding groove 25 penetrates through the inside of the translation block 26 and is parallel to the third connecting rod 22, and the translation block 26 can horizontally reciprocate along the sliding groove 25. The material moving mechanism 20 is fixed on the arm support 14 of the adjacent stamping mechanism 10 through the fixing block 29, so that the material moving mechanism 20 can move the workpiece 50 on the stamping mechanism 10 through the rotation of the gear set 24. The first suction unit 21 includes a first connection block 211 connected to the third connection rod 22, and first vacuum chucks 212 uniformly arranged on the first connection block 211, and the uniformly arranged first vacuum chucks 212 can achieve uniform suction of the first suction unit 21 to the workpiece 50, thereby more stably transferring the workpiece 50.

When the transfer mechanism 20 is required to transfer the workpiece 50, the motor 23 drives the first gear 241 to rotate, so as to drive the second gear 242 meshed with the first gear 241 to rotate, and since the fixed block 29 is fixed on the arm support 14, the end of the second connecting rod 28 connected with the fixed block 29 and the chute 25 remain in a fixed state, the second gear 242 rotates to rotate the first connecting rod 27 and the second connecting rod 28, so as to drive the translation block 26 connected with the first connecting rod 27 to move along the chute 25, and the translation block 26 moves along the chute 25 to drive the third connecting rod 22 connected with the translation block 26 to move, so as to drive the first vacuum chuck 212 connected with the third connecting rod 22 to move in a direction parallel to the chute 25 (i.e. move along a direction X), thereby transferring the workpiece 50 from the punching mechanism 10a to the punching mechanism 10b. When the workpiece 50 is punched in the punching mechanism 10a, the fixing section 1313 loosens the workpiece 50, the first suction member 21 on the stock transfer mechanism 20 sucks the workpiece 50, and the first link 27 and the second link 28 are driven by the motor 23, so that the workpiece 50 is transferred from the punching mechanism 10a to the punching mechanism 10b, and the next punching is completed in the punching mechanism 10b.

Referring to fig. 1 and 9, the computer case stamping apparatus 100 further includes a take-out rack 30, and a take-out mechanism 40 that sucks the workpiece 50 from the take-out rack 30 and transfers the workpiece 50 to the stamping mechanism 10 or sucks the workpiece 50 from the stamping mechanism 10 and transfers the workpiece 50 to the take-out rack 30. The material taking mechanism 40 includes a second adsorption assembly 44 for adsorbing the workpiece 50, a rotary table 41 for supporting the material moving mechanism 20 and axially rotating the material moving mechanism 20 (i.e., rotating along the axis O), a lifting frame 42 connected to the rotary table 41 and longitudinally moving the second adsorption assembly 44, and an electric guide rail 43 fixedly connected to the lifting frame 42 and controlling the second adsorption assembly 44 to extend in the horizontal direction. The second suction assembly 44 includes a second connection block 441 connected to the motor rail 43, and second vacuum chucks 442 and nozzles 443 uniformly distributed on the second connection block 441. The rotary table 41 is configured to drive the lifting frame 42 to rotate axially along the axis O (i.e., rotate along the axis O), and further drive the electric rail 43 and the second suction assembly 44 connected to the lifting frame 42 to rotate axially along the axis O (i.e., rotate along the axis O). The lifting frame 42 is used for driving the motor guide rail 43 and the second adsorption assembly 44 to longitudinally move. The electric rail 43 is used for driving the second adsorption assembly 44 to extend in the horizontal direction, so that the second adsorption assembly 44 can adsorb the workpiece 50 on the material taking frame 30 and the workpiece 50 on the stamping mechanism 10 under the cooperation of the rotary table 41, the lifting frame 42 and the electric rail 43. The second vacuum chuck 442 is configured to attract the workpiece 50, and the showerhead 443 is configured to eject an air flow to remove particles (e.g., dust, stamping waste, etc.) from the workpiece 50.

When the workpiece 50 needs to be punched, the second vacuum chuck 442 of the material taking mechanism 40 adsorbs the workpiece 50 on the material taking frame 30, and the workpiece 50 is transferred from the material taking frame 30 to the chassis 121 of the punching mechanism 10 through the cooperation of the rotary table 41, the lifting frame 42 and the electric guide rail 43. When the punched workpiece 50 needs to be transferred to the material taking frame 30, the second vacuum chuck 442 of the material taking mechanism 40 adsorbs the workpiece 50 on the punching mechanism 10, and the workpiece 50 is transferred from the punching mechanism 10 to the material taking frame 30 through the cooperation of the rotary table 41, the lifting frame 42 and the electric guide rail 43. Preferably, the material taking frame 30 is welded with a limiting plate 31, so that the workpiece 50 can be integrally arranged in the limiting plate 31, and the material taking mechanism 40 can accurately absorb the workpiece 50.

When the workpiece 50 in the material taking frame 30 needs to be punched, the material taking mechanism 40 makes the second adsorption assembly 44 extend towards the limiting plate 31 of the material taking frame 30 through the cooperation of the rotary table 41, the lifting frame 42 and the electric guide rail 43, and adsorbs the workpiece 50 in the limiting plate 31 of the material taking frame 30 through the second vacuum chuck 442. After the second vacuum chuck 442 of the extracting mechanism 40 adsorbs the workpiece 50, the rotary table 41, the lifting frame 42 and the electric guide rail 43 cooperate to transfer the workpiece 50 to the chassis 121 of the stamping mechanism 10. When the workpiece 50 is placed on the chassis 121 of the table 12, the driving member 1321 of the driving assembly 132 moves longitudinally downward, the driving member 1321 drives the first moving member 1322 to move longitudinally downward, and thus the second moving member 1323 connected to the first moving member 1322 through the connecting member 1324 moves longitudinally downward, at this time, the free end of the fixed rod 1311 slides away from the end surface of the driving member 1321 along the first moving member 1322, so as to drive the movable rod 1312a to rotate in the direction E along the axis P where the hinge portion 1314 is located, and the movable rod 1312b opposite to the movable rod 1312a rotates in the direction F along the axis Q where the hinge portion 1314b is located, thereby the fixed segment 1313 holds the workpiece 50 against the chassis 121. When the workpiece 50 is abutted against the chassis 121, the hydraulic cylinder 113 drives the guide rod 111 to longitudinally move downwards, and the guide rod 111 drives the punching plate 112 to longitudinally move downwards, so that the punching plate 112 punches the workpiece 50 positioned on the chassis 121. In the stamping process, the workpiece 50 is abutted against the chassis 121 by the fixing assembly 131, so that the workpiece 50 cannot shift in position, and the stamping machine 11 can precisely stamp the workpiece 50.

After the stamping is completed, the driving member 1321 moves longitudinally upward, and the driving member 1321 drives the first moving member 1322 to move longitudinally upward, so that the second moving member 1323 connected to the first moving member 1322 through the connecting member 1324 moves longitudinally upward, at this time, the free end of the fixed rod 1311 slides along the end surface of the first moving member 1322 away from the driving member 1321, so as to drive the movable rod 1312a to rotate along the direction C along the axis P where the hinge portion 1314a is located, and the movable rod 1312b opposite to the movable rod 1312a rotates along the direction D along the axis Q where the hinge portion 1314b is located, thereby releasing the workpiece 50 by the fixed segment 1313. The first suction unit 21 of the transfer mechanism 20 sucks the workpiece 50, and the first suction unit 21 is driven by the motor 23 to move along the chute 25 so as to transfer the workpiece 50 to the next press mechanism 10. After the workpiece 50 is punched, the material taking mechanism 40 extends the second adsorption assembly 44 towards the workpiece 50 on the chassis 121 through the cooperation of the rotary table 41, the lifting frame 42 and the electric guide rail 43, adsorbs the workpiece 50 on the chassis 121, and then transfers the workpiece 50 from the punching mechanism 10 to the material taking frame 30 through the cooperation of the rotary table 41, the lifting frame 42 and the electric guide rail 43.
