[0037] The embodiments of the present application are described in detail below, which are implemented on the premise of the technical solutions of the present application, and detailed implementation manners and specific operation processes are given, but the protection scope of the present application is not limited to the following embodiments. In the description of the present application, the words similar to "front", "back", "left", "right" and the like indicating the orientation or position relationship are only for the convenience of describing the present application and simplifying the description, and cannot be understood as indicating or implying that the devices or elements indicated must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0038] The embodiments disclose a chip punching die with a jacking function, as shown in the drawings, which comprises an upper die 1 and a lower die 2. It should be noted that the following structural directions are described after the upper and lower dies are closed, as shown in the drawings. Figures 1-16 Figure 1 Figure 6 The punch 104 is fixed on the upper die 1, and the concave die is fixed on the lower die 2. In use, the upper and lower dies 2 are respectively installed on the upper slide block and the table surface of the stamping equipment. Then the upper die 1 is lowered by the stamping equipment, so that the punch 104 on the upper die 1 is lowered and closed with the concave die of the lower die 2. The chip sheet is punched by the cooperation of the punch 104 and the concave die knife edge, so as to obtain the finished product.

[0039] ​​In actual work, after the punching, the punch 104 will punch the punched chip product into the inside of the die knife. In general, the punched product will be discharged through the blanking hole of the die, but due to the thinness of the chip material, when the punched product is discharged through the blanking hole, after the punch 104 punches the punched product on the material sheet, the punched product will move downward with the punch 104 inside the die knife. In this process, due to the thinness of the material, in order to make the cross section of the punched product more standard and the burr smaller, the gap between the punch 104 and the knife will be small, so that the punched product will be closely attached to the inner wall of the die knife after the punching is completed, so that when the punch 104 presses the punched product downward inside the knife, the end face of the punched product will be rubbed with the inner wall of the die knife, which will cause the edge of the punched product to be raised, and during the punching, the depth of the punch 104 inside the die knife is limited, and the deeper the punch 104 descends inside the knife, the longer the wear length of the punch 104 and the knife will be, so the depth of the punch 104 inside the die knife will be shallow. In general, the depth of the punch 104 inside the die is related to the thickness of the material, and only needs to be adjusted to the thickness of the material after the punching is completed, and in order to facilitate subsequent maintenance, the knife can be treated by grinding the die after wear, and the length of the die knife is generally set to have a length, so that when the lower discharge hole is discharged, a plurality of punched products will be stuck inside the die knife, and then with each punching, the punched products will be extruded through the blanking hole by the extrusion of the punched material sheet, and the punched material sheet 8 will not be supported from below, so that the deformation caused by the friction between the punched material sheet 8 and the inner wall of the knife will be increased.

[0040] In order to reduce the deformation of the punched material sheet 8 during discharge, as shown in Figure 1 and Figure 2 , a lifting mechanism 3 is arranged at the lower die 2, which lifts the punched material sheet 8 after each punching is completed, so that the punched material sheet 8 is discharged from above the knife, and the lifting mechanism 3 can support the punched material sheet 8 from below and press the punched material sheet 8 with the punch 104, so as to avoid deformation of the punched material sheet 8 when it moves upward inside the knife;

[0041] Specifically, as shown in Figures 1-4 , the lower die 2 includes a lower die seat 201, a lower pad 202 and a die seat 203, wherein the lower pad 202 is fixedly arranged above the lower die seat 201 by screws, and the die seat 203 is fixedly arranged above the lower pad 202 by screws. It should be noted that the lower die seat 201, the lower pad 202 and the die seat 203 can be positioned by pins, and the lower die seat 201 is also provided with a pressing plate slot 4, through which the lower die 2 can be fixed on the stamping equipment by a pressing plate.

[0042] The upper part of the inner part of the die holder 203 is provided with a die punching hole 5, and in order to improve the punching efficiency, the die holder 203 is provided with a plurality of die punching holes 5, in this embodiment, eight, and the eight die punching holes 5 are divided into two columns, so that in the punching work, a plurality of punching products can be obtained in one punching movement;

[0043] Because the die holder 203 is provided with a plurality of die punching holes 5, in order to facilitate the later maintenance, when the die punching hole 5 cutting edge is worn, the worn die punching hole 5 can be repaired, the die punching hole 5 is provided as an insert, specifically, the upper part of the inner part of the die holder 203 is provided with a mounting groove 7, the mounting groove 7 penetrates the upper end face of the die holder 203, the inner part of the mounting groove 7 is slidably connected with the die insert 6, and the outer wall of the die insert 6 is attached to the inner wall of the mounting groove 7, and the die punching hole 5 is provided in the inner part of the die insert 6 and penetrates the upper and lower end faces of the die insert 6, in addition, it should be noted that the die insert 6 can be detachably fixed in the inner part of the mounting groove 7, and the upper end face of the die insert 6 and the upper end face of the die holder 203 are in the same horizontal plane;

[0044] The lifting mechanism 3 is arranged below the die insert 6, in other words, the lifting mechanism 3 is arranged below each die insert 6, specifically, the lifting mechanism 3 comprises a moving groove 301, a connecting groove 302, a movable sliding block 303, a material lifting block 304 and an elastic element 305, wherein the moving groove 301 is arranged in the inside of the lower pad 202 and penetrates the upper end surface of the lower pad 202, the connecting groove 302 is arranged in the inside of the die seat 203 below, the connecting groove 302 and the die punching hole 5 are in communication with each other and are on the same vertical axis, the moving groove 301, the connecting groove 302 and the die punching hole 5 are on the same vertical axis and are in communication with each other, in addition, the length and width dimensions of the moving groove 301 are greater than those of the connecting groove 302, the movable sliding block 303 is longitudinally and slidingly inserted into the inside of the moving groove 301, because the size of the moving groove 301 is greater than that of the connecting groove 302, therefore, the movable sliding block 303 can only longitudinally slide in the moving groove 301, the material lifting block 304 is fixedly arranged on the upper end surface of the movable sliding block 303, the top end of the material lifting block 304 slidingly extends to the inside of the die punching hole 5 through the connecting groove 302, the outer wall of the material lifting block 304 is in abutment and sliding fit with the inner wall of the die punching hole 5, and the upper end surface of the material lifting block 304 is arranged to be higher than the upper end surface of the die seat 203, it should be noted that when the upper end surface of the movable sliding block 303 is in abutment with the lower end surface of the die seat 203, the upper end surface of the material lifting block 304 is higher than the upper end surface of the die seat 203, in order to make the material lifting block 304 have upward lifting force, the elastic element 305 is arranged below the movable sliding block 303, the bottom end of the elastic element 305 is in contact with the bottom wall of the moving groove 301, so that the movable sliding block 303 has upward lifting force through the elastic element 305, the material lifting block 304 can be moved upward through the elastic element 305, the material lifting block 304 moves upward to upwardly lift the punched product for discharging, and the elastic element 305 can be a spring;

[0045] In addition, a plurality of positioning pins 9 are arranged above the die seat 203, the positioning pins 9 are used for positioning the material sheet, facilitating the placement of the material sheet;

[0046] Therefore, through the setting of the jacking mechanism 3, in the actual punching movement, the material sheet is placed on the die holder 203, and then the upper die 1 is lowered, the upper die 1 is lowered, the punch 104 is lowered, the punch 104 is combined with the die hole 5 to punch the material sheet, and the punched finished material sheet 8 is pressed into the die hole by the punch 104, at this time, the material ejector 304 is also pressed down by the punch 104, and the finished material sheet 8 is located between the material ejector 304 and the punch 104 and is pressed tightly by the material ejector 304 and the punch 104, thereby avoiding deformation of the material sheet, and then the punch 104 is raised, and the elastic member 305 acts on the material ejector 304 to lift the material ejector 304, the material ejector 304 lifts the finished material sheet 8, and the finished material sheet 8 is ejected from the die hole, and when the finished material sheet 8 is raised, the punch 104 is raised, the material ejector 304 is raised by the elastic member 305 to lift the finished material sheet 8, and the finished material sheet 8 is pressed tightly between the punch 104 and the material ejector 304, so that when the end surface of the finished material sheet 8 is rubbed, it can be pressed tightly on the whole surface, thereby avoiding bending and deformation of the finished material sheet 8 due to friction with the inner wall of the die hole when it is raised, thereby reducing the deformation of the finished material sheet 8 when it is ejected;

[0047] Specifically, as shown in Figure 1 、 Figure 5 、 Figure 6 and Figure 7 , the upper die 1 comprises an upper die holder 101, an upper backing plate 102, a fixed plate 103 and a punch 104, wherein the upper die holder 101 is used to connect with the upper slide block of the stamping equipment, the upper backing plate 102 is fixedly connected below the upper die holder 101 by screws, the fixed plate 103 is fixed below the upper backing plate 102 by screws, and the punch 104 is installed on the fixed plate 103. More specifically, the fixed plate 103 is provided with a punch hole for inserting the punch 104, the punch 104 is slidingly inserted into the punch hole, and the outer wall of the punch 104 is tightly fitted with the punch hole. The top of the punch 104 is provided with a hanging table, which limits the punch 104 on the fixed plate 103. The upper backing plate 102 is used to support the punch 104. It should be noted that the upper backing plate 102 is quenched to make the hardness of the upper backing plate 102 support the punch 104, avoiding the upper backing plate 102 from being concave. In addition, the punch 104 is matched with the die hole 5 on the lower die 2 for punching, and correspondingly, the number of the punch 104 is the same as the number of the die hole 5.

[0048] Therefore, when punching, the upper die 1 is lowered by the stamping equipment, and the punch 104 on the upper die 1 is lowered and inserted into the die hole 5, thereby combining with the die to punch the material sheet on the die holder 203;

[0049] In addition, in order to press the material sheet when the upper die 1 moves down, and after the punching is completed, the waste material can be stripped from the punch 104, an outer stripping plate 10 is arranged below the fixed plate 103, and a through hole 11 matched with the punch 104 is formed in the outer stripping plate 10, and the punch 104 is slidingly inserted into the through hole 11, so that the outer stripping plate 10 can slide longitudinally on the outer wall of the punch 104, and a stripping spring 12 is arranged between the outer stripping plate 10 and the fixed plate 103, and the outer stripping plate 10 is installed below the fixed plate 103 by means of an equal height screw, and the lower end surface of the outer stripping plate 10 is below the lower end surface of the punch 104, so that when the upper die 1 moves down for blanking, the outer stripping plate 10 will first contact the material sheet on the die holder 203 and press the material sheet, and then as the upper die 1 continuously moves down, the fixed plate 103 continuously moves down and compresses the stripping spring 12, and the punch 104 will extend through the through hole 11 of the outer stripping plate 10 for blanking, and then the upper die 1 moves up, and the outer stripping plate 10 rebounds through the stripping spring 12 to strip the waste material sheet;

[0050] It should be noted that the fixed plate 103 is also provided with a guide column 13, and the die holder 203 is provided with a corresponding guide hole 14, which guides the movement of the upper die 1 when it moves down, and the lower end surface of the outer stripping plate 10 is provided with a clearance hole 15 for avoiding the positioning pin 9;

[0051] Through the above arrangement, the finished material sheet 8 can be discharged from above the die holder 203, and when the finished material sheet 8 is discharged from above, the finished material sheet 8 and the waste material sheet will be located above the die holder 203, and the worker needs to take out the waste material sheet with a tool, and then take out the finished material sheet 8, and since the waste material sheet and the finished material sheet 8 are located above the die holder 203, and the finished material sheet 8 is small in size, when the waste material sheet is taken out, the finished material sheet 8 will be clamped on the hole of the waste material sheet and be lifted, which makes it difficult to take out the material, and taking out the waste material sheet will cause the finished material sheet 8 to be shifted, which makes it difficult to ensure the position of the finished material sheet after each punching, and since one punching will have multiple finished material sheets, it is not convenient to take out the finished material sheet one by one;

[0052] Therefore, as shown in FIG. 8, a finished material sheet stripping plate 10a is arranged below the die holder 203, and a through hole 11a matched with the punch 104 is formed in the finished material sheet stripping plate 10a, and the punch 104 is slidingly inserted into the through hole 11a, so that the finished material sheet stripping plate 10a can slide longitudinally on the outer wall of the punch 104, and a stripping spring 12a is arranged between the finished material sheet stripping plate 10a and the die holder 203, and the finished material sheet stripping plate 10a is installed below the die holder 203 by means of an equal height screw, and the lower end surface of the finished material sheet stripping plate 10a is below the lower end surface of the punch 104, so that when the upper die 1 moves down for blanking, the finished material sheet stripping plate 10a will first contact the material sheet on the die holder 203 and press the material sheet, and then as the upper die 1 continuously moves down, the die holder 203 continuously moves down and compresses the stripping spring 12a, and the punch 104 will extend through the through hole 11a of the finished material sheet stripping plate 10a for blanking, and then the upper die 1 moves up, and the finished material sheet stripping plate 10a rebounds through the stripping spring 12a to strip the waste material sheet; Figure 1 、 Figure 6 、 Figure 7 and Figure 8As shown, the upper die 1 is provided with a separation mechanism 16. After the punching is completed, when the upper die 1 is moved upward for resetting, the separation mechanism 16 can suck the waste piece and move it above and away from the concave die seat 203, so that the waste piece is separated from the finished piece 8. It should be noted that, in order to avoid that the waste piece moves upward and brings the finished piece 8, the upward movement of the waste piece is arranged to be before the finished piece 8 is moved by the concave die punch 5 to the upper end face of the concave die seat 203, so that when the finished piece 8 is moved upward by the concave die punch 5 to the upper end face of the concave die seat 203, the waste piece has been moved above the concave die seat 203 by the separation mechanism 16, so as to avoid mutual interference. At the same time, the upper die 1 is also provided with a waste containing assembly 18, so that when the waste piece moves to the upper position, when the upper die 1 reaches the upper limit, the waste piece falls into the waste containing assembly 18, so that after each punching is completed, the waste piece is taken away with the upward movement of the upper die 1 and automatically falls into the waste containing assembly 18, and the worker only needs to take out the finished piece 8;

[0053] Specifically, the separation mechanism 16 includes a suction assembly 161 and a positioning assembly 162. The suction assembly 161 is used to suck the waste piece on the outer stripping plate 10 after the punching is completed. The positioning assembly 162 is used to position the height of the outer stripping plate 10 when the outer stripping plate 10 is moved upward and compressed by the concave die seat 203 outside the punch 104 during the punching. When the punch 104 enters the concave die punch 5 and completes the punching, the outer stripping plate 10 can be positioned in height by the positioning assembly 162, so that the outer stripping plate 10 is extended out of the through hole 11 of the outer stripping plate 10 at the knife edge end of the punch 104 after the punching is completed, and the knife edge of the punch 104 is below the lower end face of the outer stripping plate 10. The height position of the outer stripping plate 10 can be positioned by the positioning assembly 162, so that when the upper die 1 is raised and reset, the waste piece can be above the knife edge of the punch 104 and be sucked by the suction assembly 161. The upward movement of the upper die 1 directly drives the waste piece to move upward, so that the waste piece is separated from the concave die seat 203 before the finished piece 8 returns to above the concave die seat 203, thereby avoiding that the waste piece brings the finished piece 8;

[0054] The suction assembly 161 is provided in plurality, and the plurality of suction assemblies 161 are uniformly distributed between the outer stripping plate 10 and the fixed plate 103, so that the waste piece can be sucked by the plurality of suction assemblies 161;

[0055] More specifically, as shown in FIG. 6, the separation mechanism 16 includes a suction assembly 161 and a positioning assembly 162. The suction assembly 161 is used to suck the waste piece on the outer stripping plate 10 after the punching is completed. The positioning assembly 162 is used to position the height of the outer stripping plate 10 when the outer stripping plate 10 is moved upward and compressed by the concave die seat 203 outside the punch 104 during the punching. When the punch 104 enters the concave die punch 5 and completes the punching, the outer stripping plate 10 can be positioned in height by the positioning assembly 162, so that the outer stripping plate 10 is extended out of the through hole 11 of the outer stripping plate 10 at the knife edge end of the punch 104 after the punching is completed, and the knife edge of the punch 104 is below the lower end face of the outer stripping plate 10. The height position of the outer stripping plate 10 can be positioned by the positioning assembly 162, so that when the upper die 1 is raised and reset, the waste piece can be above the knife edge of the punch 104 and be sucked by the suction assembly 161. The upward movement of the upper die 1 directly drives the waste piece to move upward, so that the waste piece is separated from the concave die seat 203 before the finished piece 8 returns to above the concave die seat 203, thereby avoiding that the waste piece brings the finished piece 8; Figures 6-10As shown, the adsorption assembly 161 includes a fixed block 611, a piston cylinder 612, an air pipe 613, an air hole 614, a movable groove 615, a moving block 616 and a fixed rod 617, the fixed block 611 is fixedly arranged at the lower end surface of the fixed plate 103, and the lower side of the fixed block 611 is fixedly arranged with the piston cylinder 612, the piston cylinder 612 is composed of a cylinder body 6121 and an internal piston disc 6122, the piston disc 6122 is longitudinally and slidingly arranged in the internal cylinder body 6121, and the outer wall of the outer circle of the piston disc 6122 is attached to the inner wall of the cylinder body 6121, and the lower side of the cylinder body 6121 is communicated with the air pipe 613, and correspondingly, the air hole 614 is arranged at the corresponding position of the outer stripping plate 10 and the air pipe 613, and the air hole 614 penetrates the upper and lower end surfaces of the outer stripping plate 10, the air hole 614 and the air pipe 613 are on the same vertical axis, and the air pipe 613 is communicated with the air hole 614, therefore, by moving the piston disc 6122 up and down in the internal cylinder body 6121, the air pipe 613 can be used for inhaling and exhaling, when the piston disc 6122 moves up, the air hole 614 will generate suction to suck the waste sheet, and the upper end surface of the piston disc 6122 is fixedly connected with a suction rod 6123, the internal fixed block 611 is provided with a movable groove 615, and the movable groove 615 penetrates the front and rear end surfaces of the fixed block 611, and the top end of the suction rod 6123 penetrates the top wall of the cylinder body 6121 and the bottom wall of the movable groove 615 and extends into the internal movable groove 615, it should be noted that the suction rod 6123 and the top wall of the cylinder body 6121 and the bottom wall of the movable groove 615 are all in sliding fit, the internal movable groove 615 is longitudinally and slidingly arranged with a moving block 616, one end of the suction rod 6123 located in the internal movable groove 615 is fixedly connected with the bottom wall of the moving block 616, the front and rear ends of the moving block 616 extend to the front and rear ends of the fixed block 611 respectively, the front and rear ends of the moving block 616 are fixedly arranged with fixed rods 617 respectively, and the bottom end of the fixed rod 617 is fixedly connected with the outer stripping plate 10, in addition, since the fixed block 611 and the piston cylinder 612 are connected with the fixed plate 103, in order to avoid the influence of the air pipe 613 on the up and down movement of the outer stripping plate 10, the air pipe 613 is arranged as an extension pipe;

[0056] It should be noted that the position of the air hole 614 is within the range of the sheet, so that after the outer stripping plate 10 moves down and the die holder 203 presses the sheet tightly, the sheet can cover the air hole 614, in addition, the air hole 614 is staggered with the die punching hole 5;

[0057] Therefore, through the above setting, when the upper die 1 moves downward for punching, the outer stripping plate 10 first contacts the concave die seat 203 and presses the material piece, and then the fixing plate 103 continuously moves downward with the upper die 1, while the outer stripping plate 10 stops moving downward. The downward movement of the fixing plate 103 makes the punch 104 blade protrude downward through the through hole 11 of the outer stripping plate 10, and the punch 104 blade enters the inside of the concave die hole 5 to punch the material piece. At this time, since the fixing block 611 and the piston cylinder 612 are connected with the fixing plate 103, and the moving block 616 is connected with the outer stripping plate 10 through the fixing rod 617, when the fixing plate 103 moves downward, the fixing block 611 and the piston cylinder 612 move downward, while the moving block 616 and the fixing rod 617 remain stationary. Since the pull rod 6123 is connected with the moving block 616, when the piston cylinder 612 moves downward, the piston cylinder 612 moves downward outside the piston disc 6122, in other words, the piston disc 6122 moves upward inside the piston cylinder 612, so that the air pipe 613 inhales air, the air pipe 613 is communicated with the air hole 614, so that the air hole 614 inhales air, thereby sucking the waste material piece through the air hole 614;

[0058] As Figures 6-13As shown, the positioning assembly 162 comprises a positioning hole 621, a positioning plug 622, a through slot 623, an inner baffle 624, a connecting plate 625, a sliding rod 626, a reset spring 627 and an outer baffle 628. The positioning hole 621 is formed in the inner part of the moving block 616, and penetrates through the two side end faces of the moving block 616. The through slot 623 is formed in the outer wall of the movable slot 615, and penetrates through the side end face of the fixed block 611 and the inner wall of the movable slot 615. The positioning plug 622 is slidably connected in the through slot 623, and the size of the positioning plug 622 is configured to be matched with the positioning hole 621. It should be noted that the positioning plug 622 is located above the moving block 616, and one end of the positioning plug 622 extends into the movable slot 615. The end face of the positioning plug 622 located in the movable slot 615 is beveled, and the angle of the bevel is configured so that when the moving block 616 moves upward, the positioning plug 622 can be pressed and moved towards the inside of the through slot 623 through the contact between the moving block 616 and the bevel of one end of the positioning plug 622. The other end of the positioning plug 622 is fixedly provided with the inner baffle 624, and the inner baffle 624 is located on one side of the fixed block 611. The inner baffle 624 positions the positioning plug 622. The inner baffle 624 is further provided with the connecting plate 625, and the connecting plate 625 is fixedly connected with the fixed block 611 through a support plate. The inner baffle 624 is further fixedly provided with the sliding rod 626, and the other end of the sliding rod 626 slidably extends to one side of the connecting plate 625. The outer baffle 628 is fixedly arranged at one end of the sliding rod 626 located on one side of the connecting plate 625, and the outer baffle 628 positions the sliding rod 626. The outer wall of the sliding rod 626 is further sleeved with the reset spring 627, and the reset spring 627 is located between the connecting plate 625 and the inner baffle 624. The reset spring 627 rebounds the inner baffle 624 towards the movable slot 615, so that one end of the positioning plug 622 is located in the movable slot 615.

[0059] With the above arrangement, when the fixed plate 103 moves down, the fixed block 611 moves down outside the moving block 616. Through the arrangement of the inclined surface of one end of the positioning plug block 622, when the inclined surface of the positioning plug block 622 contacts the outer wall of the moving block 616, the positioning plug block 622 can be moved towards the inside of the through groove 623. When the positioning plug block 622 moves to align with the positioning hole 621, the positioning plug block 622 is inserted into the inside of the positioning hole 621 through the action of the reset spring 627. The height of the outer stripping plate 10 is limited through the cooperation of the positioning plug block 622 and the positioning hole 621. After punching, the cutting edge end of the punch 104 extends out of the through hole 11 of the outer stripping plate 10. When the cutting edge of the punch 104 is below the lower end surface of the outer stripping plate 10 and the punch 104 is still located in the die hole 5, the height position of the outer stripping plate 10 can be positioned. When the upper die 1 rises and resets, the waste sheet can be located above the cutting edge of the punch 104 and be adsorbed by the air hole 614. The upper die 1 moves up to move the waste sheet up. Before the finished sheet 8 returns to above the die holder 203, the waste sheet is separated from the die holder 203, thereby avoiding that the waste sheet lifts the finished sheet 8;

[0060] When the upper die 1 returns to the upper limit position, the waste sheet is removed, as shown in Figure 7 、 Figure 14 and Figure 15 , the unlocking assembly 17 is further arranged. After the upper die 1 returns to the upper limit position and the finished sheet 8 moves to above the die holder 203, the positioning plug block 622 is separated from the positioning hole 621, so that the outer stripping plate 10 can move down to push the waste sheet down for removal under the action of the stripping spring 12.

[0061] Specifically, the unlocking assembly 17 includes a connecting rope 171, a connecting ring 172 and a guide wheel 173. One side of each outer baffle 628 is fixedly connected with the connecting rope 171, and the other end of the connecting rope 171 is connected with the connecting ring 172. The connecting ring 172 is detachably connected with the die holder 203, which can be detachably connected by threads or the like. In addition, a guide wheel strip is fixedly arranged on the side of the fixed plate 103. The bottom end of the guide wheel strip is provided with the guide wheel 173. The connecting rope 171 can be guided downward from one side between the outer stripping plate 10 and the fixed plate 103 through the guide wheel 173. It should be noted that the length of the connecting rope 171 is configured to be taut when the upper die 1 returns to the upper limit position. The taut connecting rope 171 pulls the outer baffle 628 outward, so that the positioning plug block 622 is separated from the positioning hole 621.

[0062] Therefore, after each punching operation, when the upper die 1 returns to its upper limit, the positioning block 622 is pulled by the connecting rope 171, causing the positioning block 622 to separate from the positioning hole 621. Without the positioning block 622 and the positioning hole 621 for insertion and limiting, the outer stripping plate 10 is moved down by the stripping spring 12 to strip the waste sheet. After the outer stripping plate 10 moves down, the moving block 616 moves back to below the positioning block 622. When the upper die 1 moves down to continue punching, the connecting rope 171 loosens, and the reset spring 627 rebounds the positioning block 622, so that one end of the positioning block 622 is located inside the movable groove 615.

[0063] In order to collect the waste material after stripping and prevent it from falling back onto the die holder 203, such as Figure 1 As shown, the waste collection assembly 18 is configured to include a foot 181, a slide 182, a collection frame 183, and an electric push rod 184. The foot 181 is located behind the die base 203 and is fixed to the upper part of the lower die base 201 by screws. The slide 182 is fixedly located above the foot 181. The collection frame 183 is slidably arranged above the slide 182, and the collection frame 183 is higher than the die base 203 in height. The collection frame 183 is located above the rear end of the die base 203. An electric push rod 184 is provided at the rear end of the holding frame 183, and the electric push rod 184 is fixedly installed on the slide 182. The telescopic shaft of the electric push rod 184 is fixedly connected to the outer wall of the holding frame 183, and the extension direction of the electric push rod 184 is towards the die seat 203. Thus, the holding frame 183 can be pushed towards the die seat 203 by the electric push rod 184, so that the holding frame 183 can be moved between the die seat 203 and the upper mold 1 for holding the stripped waste sheet;

[0064] The activation of the electric actuator 184 is controlled by sensor 20, specifically, as follows: Figure 1 and Figure 16As shown, the side of the upper die holder 101 is fixedly provided with a mounting plate 19, and the sensor 20 is mounted above the mounting plate 19. The sensor 20 is arranged as a proximity sensor 20. The lower die holder 201 is fixedly provided with a support plate 21 at a corresponding position. The support plate 21 is fixedly provided with a horizontal plate 22 above. The horizontal plate 22 is above the mounting plate 19. The horizontal plate 22 is provided with an induction plate 23 below. The induction plate 23 is longitudinally movably arranged below the horizontal plate 22 through a slide shaft 24. The induction plate 23 is also above the mounting plate 19 and the sensor 20. In addition, it should be noted that the induction plate 23, the horizontal plate 22 and the mounting plate 19 are all on the same vertical axis. The sensor 20 is electrically connected with the electric push rod 184. When the upper die 1 is reset and moves upward, the sensor 20 contacts the induction plate 23 after the upper die holder 101 moves upward. The electric push rod 184 is started to move the holding frame 183 toward the concave die holder 203 to hold the waste pieces. By arranging the induction plate 23, the sensor 20 contacts the induction plate 23 before the upper die holder 101 returns to the upper limit. The holding frame 183 is moved between the concave die holder 203 and the outer stripping plate 10 before the waste pieces are stripped. Then the upper die holder 101 continues to move upward. The induction plate 23 can continue to move upward through the slide shaft, so as to avoid affecting the resetting of the upper die 1.

[0065] In addition, it should be noted that the position of the induction plate 23 is higher than the position of the holding frame 183. The electric push rod 184 can be controlled by the sensor 20 to move once. Then the electric push rod 184 is moved above the concave die holder 203 to hold the stripped waste pieces. Alternatively, the electric push rod 184 can be controlled by the sensor 20 to extend, and then be retracted by pressing the button by the worker.

[0066] Therefore, through the above arrangement, the waste pieces are separated from the finished pieces 8 after each punching is completed. The plurality of finished pieces 8 are individually located on the concave die holder 203. The plurality of finished pieces 8 are all located at the same position as the concave die punching 5. Therefore, a dedicated material taking clamp tool can be arranged to take out the plurality of finished pieces 8 at one time. The position deviation of the finished pieces 8 caused by the waste pieces can be avoided to affect the convenience of taking the material.

[0067] The principle of the present application is as follows: in actual work, the material sheet is placed on the concave die seat 203, then the upper die 1 moves down, the punch 104 moves down, the punch 104 is combined with the concave die hole 5 to punch the material sheet, and the finished product material sheet 8 is pressed into the hole by the punch 104, at this time, the material ejecting block 304 is also pressed down by the punch 104, the finished product material sheet 8 is located between the material ejecting block 304 and the punch 104 and is pressed tightly by the material ejecting block 304 and the punch 104, so as to avoid deformation of the material sheet, then the punch 104 moves up, and the elastic member 305 acts on the material ejecting block 304, the material ejecting block 304 ejects the finished product material sheet 8, and when the finished product material sheet 8 moves up, the punch 104 moves up at the same time, the material ejecting block 304 moves up the finished product material sheet 8 under the action of the elastic member 305, and the finished product material sheet 8 is pressed tightly between the punch 104 and the material ejecting block 304, so that when the end surface of the finished product material sheet 8 is rubbed, the whole surface can be pressed tightly, thereby avoiding the finished product material sheet 8 from being bent and deformed due to friction with the inner wall of the hole when moving up, so as to reduce the deformation of the finished product material sheet 8 when discharging, after the punching is completed, when the upper die 1 moves up and resets, the adsorption assembly 161 can adsorb the waste material sheet and move to above and away from the concave die seat 203, so as to separate the waste material sheet from the finished product material sheet 8, and in order to avoid the waste material sheet from taking the finished product material sheet 8 when moving up, the positioning assembly 162 is used to position the height of the outer stripping plate 10 when the punch 104 enters the concave die hole 5 and completes the punching, so that the outer stripping plate 10 extends out of the through hole 11 of the outer stripping plate 10 at the knife edge end of the punch 104, and the knife edge of the punch 104 is located below the lower end surface of the outer stripping plate 10, and the height position of the outer stripping plate 10 is positioned by the positioning assembly 162, so that when the upper die 1 moves up and resets, the waste material sheet can be located above the knife edge of the punch 104 and is adsorbed by the adsorption assembly 161, and the upper die 1 directly drives the waste material sheet to move up, so that the waste material sheet is separated from the concave die seat 203 before the finished product material sheet 8 moves to above the concave die seat 203, thereby avoiding the waste material sheet from taking the finished product material sheet 8.

[0068] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalents of the claims are intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
