DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0028] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a trimming machine 1000 provided in an embodiment of the present application, Figure 2 yes Figure 1 The structure diagram of the trimming die 500 in the trimming machine 1000 is shown. For the convenience of description, the length direction of the trimming die 500 is defined as the X-axis direction, the width direction of the trimming die 500 is defined as the Y-axis direction, and the height direction of the trimming die 500 is defined as the Z-axis direction.
[0029] In this embodiment, the trimming machine 1000 (not shown) can be used to trim the bright aluminum decorative strips of the vehicle waiting for trimming (not shown). Exemplarily, the trimming parts can be sheet metal stamping parts. The trimming machine 1000 can include a support frame 400, a pusher 300 and a trimming die 500. Among them, the pusher 300 is installed on the support frame 400 and can move relative to the support frame 400 along the height direction of the trimming machine 1000 (Z-axis direction shown in the figure). The trimming die 500 is arranged inside the support frame 400 and is connected to the pusher 300.
[0030] In this embodiment, the trimming mold 500 includes a first trimming module 100 and a second trimming module 200. Along the height direction of the trimming mold 500 (Z-axis direction as shown in the figure), the first trimming module 100 and the second trimming module 200 are arranged relatively. Specifically, the first trimming module 100 is installed inside the support frame 400 and is located at the bottom of the pusher 300. Along the height direction of the trimming machine 1000 (Z-axis direction as shown in the figure), the first trimming module 100 and the pusher 300 are spaced and arranged relatively. The second trimming module 200 is fixedly installed on the side of the pusher 300 facing the first trimming module 100, and can be moved relative to the first trimming module 100 along the height direction of the trimming machine 1000 (Z-axis direction as shown in the figure) under the drive of the pusher 300.
[0031] It should be noted that the directional words such as "top" and "bottom" involved in this application are referenced to the attached Figure 1 The description of the orientation shown, with the positive direction of the Z-axis as the "top" and the negative direction of the Z-axis as the "bottom", does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0032] Please refer to Figure 3 and Figure 4 , Figure 3 yes Figure 2 The schematic structural diagram of the first trimming module 100 in the trimming mold 500 is shown. Figure 4 yes Figure 3 A schematic structural diagram of the first base 110 in the first trimming module 100 is shown.
[0033] The first trimming module 100 includes a first base 110, a support member 120, a first stop member 130, a plurality of waste knives 140, a discharging member 150, a plurality of first limiting posts 160, a plurality of first positioning members 170, a plurality of pads 180 and a plurality of limiting blocks. Among them, the support member 120, the first stop member 130, a plurality of waste knives 140, the discharging member 150, a plurality of first limiting posts 160, a plurality of first positioning members 170 and a plurality of pads 180 are all installed on the first base 110. Specifically, the support member 120, the first stop member 130, a plurality of waste knives 140, the discharging member 150, a plurality of first limiting posts 160, a plurality of first positioning members 170 and a plurality of limiting blocks are all arranged on the side of the first base 110 facing the second trimming module 200, and the plurality of pads 180 are all arranged on the side of the first base 110 away from the second trimming module 200.
[0034] In this embodiment, the first base 110 includes a first surface 114 and a second surface 115. Along the thickness direction of the first base 110 (Z-axis direction in the figure), the first surface 114 and the second surface 115 are arranged opposite to each other. The first base 110 also includes a first mold base 10 and a first fixed plate 20. The first fixed plate 20 is fixedly installed on the surface of the first mold base 10 facing the second trimming mold set 200. Among them, the first fixed plate 20 includes a first end surface 21 and a second end surface 22. Along the length direction of the first fixed plate 20 (X-axis direction in the figure), the first end surface 21 and the second end surface 22 are arranged opposite to each other.
[0035] The first base 110 is also provided with a discharge hole 111 and a discharge trough 112. The discharge hole 111 penetrates the first surface 114 and the second surface 115 of the first base 110 along the thickness direction (Z-axis direction in the figure) of the first base 110. The discharge hole 111 includes a plurality of sub-discharge holes 1111. The plurality of sub-discharge holes 1111 are arranged at intervals from each other.
[0036] The discharge trough 112 is arranged on the side of the waste knife 140 away from the discharge hole 111. The opening of the discharge trough 112 is located on the surface of the first base 110 facing the second trimming module 200. That is, the opening of the discharge trough 112 is located on the first surface 114. Specifically, the discharge trough 112 is recessed from the first surface 114 to the second surface 115, and passes through the end surface of the first base 110 in the length direction. Among them, the bottom wall surface of the discharge trough 112 includes a first end 1121 close to the waste knife 140 and a second end 1122 arranged opposite to the first end 1121. The first end 1121 and the second end 1122 are both located on the side of the blade of the waste knife 140 close to the first base 110. Along the height direction of the trimming mold 500 (Z-axis direction in the figure), the distance between the second end 1122 and the blade of the waste knife 140 is greater than the distance between the first end 1121 and the blade of the waste knife 140. That is, the bottom wall of the discharge trough 112 is inclined.
[0037] It can be understood that some of the waste pieces obtained after the trimming process will fall into the discharge chute 112. By tilting the bottom wall of the discharge chute 112, the waste pieces falling into the discharge chute 112 can slide out of the trimming mold 500 smoothly, thereby making it easier for production personnel to collect and clean the waste pieces.
[0038] In this embodiment, there are two discharge slots 112. The two discharge slots 112 are respectively a first discharge slot 112a and a second discharge slot 112b. The first discharge slot 112a also passes through the first end surface 21 of the first fixing plate 20. The second discharge slot 112b also passes through the second end surface 22 of the first fixing plate 20.
[0039] Please continue reading Figure 3 The support member 120, the first stop member 130 and the plurality of waste cutters 140 are all mounted on the surface of the first base 110 facing the second trimming module 200. Specifically, the support member 120, the first stop member 130 and the plurality of waste cutters 140 are all mounted on the surface of the first fixed plate 20 away from the first die base 10. In this embodiment, the support member 120, the first stop member 130 and the plurality of waste cutters 140 and other components are mounted on the first fixed plate 20 by means of inlay. Under this arrangement, on the one hand, production materials can be saved and the installation space occupied by components such as the support member 120, the first stop member 130 and the multiple waste knives 140 can be reduced; on the other hand, production personnel can easily observe the structures of components such as the support member 120, the first stop member 130 and the multiple waste knives 140, and can promptly discover tooling problems of the first trimming module 100, which is convenient for production personnel to subsequently repair and replace components such as the support member 120, the first stop member 130 and the multiple waste knives 140, thereby helping to reduce the repair time of production personnel and improve their work efficiency.
[0040] Specifically, the support member 120 is mounted on the surface of the first fixed plate 20 away from the first mold base 10. The discharge hole 111 provided on the first base 110 is arranged around the outer periphery of the support member 120, and a plurality of sub-discharge holes 1111 are arranged at intervals around the outer periphery of the support member 120. The support member 120 has a support surface 121 away from the first base 110. The support surface 121 is used to support the workpiece to be trimmed.
[0041] In this embodiment, the plurality of limit blocks include a first limit block 191 and a second limit block 192. Along the width direction of the support member 120, the first limit block 191 and the second limit block 192 are respectively located on opposite sides of the support surface 121 of the support member 120. The first limit block 191 is mounted on the support member 120. The second limit block 192 is mounted on the first base 110 and is located on the side of the opening of the discharge hole 111 away from the support member 120. Exemplarily, there are a plurality of first limit blocks 191 and a plurality of second limit blocks 192 respectively. The plurality of first limit blocks 191 are arranged at intervals from each other, and the plurality of second limit blocks 192 are arranged at intervals from each other. When the piece to be trimmed is placed on the support member 120, the support surface 121 supports the piece to be trimmed, and the first limit block 191 and the second limit block 192 respectively abut against opposite sides of the piece to be trimmed to limit the piece to be trimmed, thereby preventing the position of the piece to be trimmed from being offset, thereby helping to improve the trimming accuracy of the trimming mold 500.
[0042] A plurality of waste cutters 140 are arranged at intervals around the outer circumference of the support member 120. Specifically, the plurality of waste cutters 140 are all located on the side of the support member 120 away from the plurality of first limit blocks 191. Each waste cutter 140 is located between two adjacent sub-discharging holes 1111.
[0043] In addition, the scrap knife 140 includes a guide surface 141. The guide surface 141 is located on the side of the blade of the scrap knife 140 facing the discharge chute 112. The guide surface 141 includes a first side 1411 close to the blade of the scrap knife 140 and a second side 1412 arranged opposite to the first side 1411. Along the height direction of the trimming mold 500 (Z-axis direction in the figure), the distance between the second side 1412 and the blade of the scrap knife 140 is greater than the distance between the first side 1411 and the blade of the scrap knife 140. That is, the guide surface 141 of the scrap knife 140 is arranged to be inclined toward the discharge chute 112.
[0044] It is understandable that the waste cutter 140 is used to segment the waste pieces generated after trimming the trimming pieces, so that the waste pieces can fall from the discharge hole 111 into the waste box provided at the bottom of the trimming die 500, so that the trimming die 500 can discharge the waste downward. At the same time, by providing a guide surface 141 on the waste cutter 140 and making the guide surface 141 inclined, the waste pieces can slide smoothly into the discharge trough 112 along the guide surface 141 after segmentation, and slide out of the trimming die 500 from the discharge trough 112, so as to help production personnel collect and clean up the waste pieces.
[0045] The first stopper 130 is located at the side of the opening of the discharge hole 111 away from the support member 120. Exemplarily, there are multiple first stoppers 130. Multiple first stoppers 130 are arranged at intervals from each other. When the second trimming module 200 contacts the first trimming module 100, the first stopper 130 can prevent the second trimming module 200 from generating lateral force, avoiding lateral load on the second trimming module 200, thereby helping to improve the stability of the trimming die 500 during the trimming process and avoiding the occurrence of knife gnawing.
[0046] In this embodiment, the discharge piece 150 is installed on the first mold base 10 of the first base 110 and is located on the side of the discharge slot 112 away from the waste knife 140. Exemplarily, the discharge piece 150 is fixed to the first mold base 10 by screwing. The discharge piece 150 can be made of 45# stainless steel material or P20 stainless steel material, and the embodiments of the present application do not impose any restrictions on this.
[0047] In this embodiment, the discharge member 150 is provided with a guide groove 151. The guide groove 151 is connected with the discharge groove 112. Specifically, the guide groove 151 has a guide outlet 1511 away from the discharge groove 112, and the guide outlet 1511 extends relative to the outer peripheral surface of the first base 110. Under this arrangement, it is convenient for the waste parts to slide from the discharge groove 112 into the guide groove 151, and slide out of the trimming mold from the guide outlet 1511 of the guide groove 151, so that the production personnel can collect and clean the waste parts.
[0048] In this embodiment, there are two discharge members 150. The two discharge members 150 are respectively a first discharge member 150a and a second discharge member 150b. Along the length direction of the trimming die 500 (the X-axis direction in the figure), the first discharge member 150a and the second discharge member 150b are respectively arranged on opposite sides of the first fixed plate 20 of the first base 110. Among them, the guide groove 151 of the first discharge member 150a is connected to the first discharge groove 112a. The guide groove 151 of the second discharge member 150b is connected to the second discharge groove 112b.
[0049] It can be understood that the waste pieces generated after the trimming process of the trimming pieces are segmented by multiple waste knives 140, and multiple waste segments are obtained. Among them, a part of the waste segments directly falls into the waste box at the bottom of the trimming mold 500 through the discharge hole 111, and a part of the waste segments falls into the first discharge trough 112a, and slides into the guide trough 151 of the first discharge piece 150a through the first discharge trough 112a, and then slides out of the first trimming module 100 through the guide trough 151 of the first discharge piece 150a. Another part of the waste segments falls into the second discharge trough 112b, and slides into the guide trough 151 of the second discharge piece 150b through the second discharge trough 112b, and then slides out of the first trimming module 100 through the guide trough 151 of the second discharge piece 150b. Finally, the waste segments sliding out through the guide groove 151 of the first discharging member 150a and the guide groove 151 of the second discharging member 150b can enter the waste bin through the conveyor belt, thereby completing the collection and cleaning of the waste pieces generated by the pieces to be trimmed.
[0050] Please continue reading Figure 3 The plurality of feet 180 are all located on the side of the first mold base 10 of the first base 110 away from the first fixed plate 20, and are spaced apart from each other. The feet 180 can be used to increase the overall height of the first trimming module 100. The plurality of first limiting posts 160 and the plurality of first positioning members 170 are all located on the side of the first mold base 10 facing the second trimming module 200, and are all arranged around the outer circumference of the first fixed plate 20. The plurality of first limiting posts 160 and the plurality of first positioning members 170 are spaced apart from each other.
[0051] Please refer to Figures 5 to 7 , Figure 5 yes Figure 2 The schematic structural diagram of the second trimming module 200 in the trimming mold 500 is shown. Figure 6 yes Figure 5 The partial structural diagram of the second trimming module 200 is shown in FIG. Figure 7 yes Figure 5 The second trimming module 200 is shown as a schematic structural diagram after being cut along AA. Here, “cut along AA” means cutting along the plane where the AA line is located, and similar descriptions in the following text can be understood in the same way.
[0052] The second trimming module 200 includes a second base 210, a press plate 220, a cutter 230, a second stop 240, an inner guide column 250, a fastener 260, an elastic member 270, a plurality of second limit columns 280, and a plurality of second positioning members 290. The press plate 220, the cutter 230, the second stop 240, the elastic member 270, the plurality of second limit columns 280, and the plurality of second positioning members 290 are all installed on the side of the second base 210 facing the first trimming module 100. The inner guide column 250 is installed on the second base 210 and the press plate 220. The fastener 260 is installed on the press plate 220 and the second base 210, and is spaced apart from the inner guide column 250.
[0053] Please also read Figure 8 , Figure 8 yes Figure 5 The second trimming module 200 is a partial structural schematic diagram after being cut along line BB.
[0054] In this embodiment, the second base 210 further includes a second mold base 50 and a second fixed plate 60. The second mold base 50 is connected to the pusher 300. The second fixed plate 60 is installed on the side of the second mold base 50 away from the pusher 300. That is, the second fixed plate 60 is installed on the side of the second mold base 50 facing the first trimming module 100. The second base 210 is also provided with a second assembly hole 211 and a second mounting hole 212. The openings of the second assembly hole 211 and the second mounting hole 212 are both located on the surface of the second fixed plate 60 of the second base 210 facing the first trimming module 100. The second assembly hole 211 penetrates the second mold base 50 and the second fixed plate 60 of the second base 210 along the thickness direction of the second base 210, and is spaced apart from the second mounting hole 212. Exemplarily, there are a plurality of second assembly holes 211, and the plurality of second assembly holes 211 are spaced apart. The second mounting hole 212 is recessed from the surface of the second fixing plate 60 toward the first trimming module 100 toward the second die base 50. Exemplarily, there are a plurality of second mounting holes 212, and the plurality of second mounting holes 212 are spaced apart from each other.
[0055] The blank holder 220 is mounted on the surface of the second fixing plate 60 away from the second die base 50. Along the height direction of the trimming die 500 (Z-axis direction in the figure), the blank holder 220 is arranged opposite to the support member 120 of the first trimming die set 100. The blank holder 220 can be used in conjunction with the support member 120 of the first trimming die set 100 to hold down the trimming piece to prevent the trimming piece from running away during the trimming process, thereby helping to ensure the accuracy of trimming.
[0056] In this embodiment, the pressing plate 220 is provided with a first assembly hole 221 and a first mounting hole 222, and the first assembly hole 221 and the first mounting hole 222 penetrate the pressing plate 220 along the thickness direction of the pressing plate 220, and are spaced apart from each other. Among them, the first assembly hole 221 is connected to the second assembly hole 211. Exemplarily, there are multiple first assembly holes 221. Multiple first assembly holes 221 are spaced apart from each other. Each first assembly hole 221 is connected to a second assembly hole 211. The first mounting hole 222 is connected to the second mounting hole 212. Exemplarily, there are multiple second mounting holes 212. Multiple second mounting holes 212 are spaced apart from each other. Each first mounting hole 222 is connected to a second mounting hole 212.
[0057] In the present embodiment, the fasteners 260 are used to connect the press plate 220 and the second fixed plate 60. Specifically, the fasteners 260 are provided in the first mounting hole 222 and the second mounting hole 212, and are fixed to the second fixed plate 60 of the second base 210. Exemplarily, the fasteners 260 are unloading bolts. Among them, the fasteners 260 are MISUMI / Punch standard parts. In the present embodiment, there are multiple fasteners 260. Each fastener 260 is provided in a second mounting hole 212 and a first mounting hole 222, and is fixedly connected to the second fixed plate 60, so that the press plate is connected to the second fixed plate 60.
[0058] In this embodiment, the elastic member 270 is embedded in the side of the second fixing plate 60 of the second base 210 facing the pressing plate 220. Among them, one end of the elastic member 270 facing away from the second base 210 is exposed relative to the surface of the second fixing plate 60 of the second base 210 facing the pressing plate 220. When the second trimming module 200 is molded with the first trimming module 100, the elastic member 270 abuts against the pressing plate 220 to provide a force to press the trimming member with the pressing plate 220 of the second trimming module 200. Exemplarily, there are multiple elastic members 270, and the multiple elastic members 270 are arranged at intervals. Exemplarily, the multiple elastic members 270 are all nitrogen springs. Among them, the multiple elastic members 270 are all MISUMI / Punch standard parts.
[0059] It is understandable that when the second trimming module 200 is molded with the first trimming module 100, the pressing plate 220 abuts against the part to be trimmed. At this time, the pressing plate 220 will move relative to the second fixed plate 60 of the second base 210 along the height direction of the trimming mold 500 (Z-axis direction in the figure) and move toward the direction of the second fixed plate 60. In this process, the pressing plate 220 will squeeze the elastic member 270. After being squeezed, the elastic member 270 will be deformed and generate elastic force, and the reaction force of the elastic force will act on the pressing plate 220, so as to provide the pressing plate 220 with a force to press the part to be trimmed. In addition, by providing a plurality of elastic members 270 arranged at intervals, the force of the elastic members 270 on the pressing plate 220 can be evenly distributed, so that the pressing plate 220 is balanced in force, which helps the pressing plate 220 to press the trimming member and prevent the part to be trimmed from running.
[0060] In this embodiment, the inner guide pillar 250 is inserted into the first assembly hole 221 and the second assembly hole 211, and is fixed to the second base 210 and the pressing plate 220. Exemplarily, there are multiple inner guide pillars 250. Multiple inner guide pillars 250 are arranged at intervals from each other. Exemplarily, multiple inner guide pillars 250 are all MISUMI / Punch standard parts. Specifically, each inner guide pillar 250 is inserted into a first assembly hole 221 and a second assembly hole 211, and is fixed to the second base 210 and the pressing plate 220. The inner guide pillar 250 can guide and support the components in the second trimming module 200, ensure that the second trimming module 200 moves smoothly and accurately, prevent the second trimming module 200 from deviating from the established motion track, and ensure that the second trimming module 200 has good reliability in use.
[0061] Please continue reading Figure 6 . The cutting blade 230 is connected to the pressing plate 220 and is arranged around the outer peripheral side of the pressing plate 220. Along the height direction of the trimming mold 500, the cutting blade 230 is arranged opposite to the discharge hole 111. The cutting blade 230 is used to perform trimming processing on the trimming piece to be trimmed, so as to cut off the scraps on the outer peripheral side of the trimming piece to be trimmed. The cutting blade 230 is provided with a plurality of avoidance notches 231. The openings of the plurality of avoidance notches 231 are all located on the surface of the second fixed plate 60 of the cutting blade 230 away from the second substrate. The plurality of avoidance notches 231 are all recessed from the surface of the cutting blade 230 away from the second fixed plate 60 toward the direction of the second fixed plate 60, and penetrate the surface of the cutting blade 230 in the thickness direction. The plurality of avoidance notches 231 are arranged at intervals from each other. When the second trimming module 200 and the first trimming module 100 are combined, each avoidance gap 231 avoids a waste knife 140 to avoid the cutting blade 230 and the waste knife 140 from wearing due to interference, thereby facilitating extending the service life of the trimming mold 500 .
[0062] The cutting blade 230 further includes a plurality of sub-cutters 232. Exemplarily, the plurality of sub-cutters 232 are sequentially arranged around the outer peripheral side of the pressing plate 220. During the trimming process, the plurality of sub-cutters 232 simultaneously punch the edge-cutting piece to be trimmed, so as to completely cut off the edge scraps on the outer peripheral side of the edge-cutting piece to be trimmed.
[0063] The second stopper 240 is arranged on the side of the cutting blade 230 away from the pressing plate 220, and abuts against the cutting blade 230. The surface of the cutting blade 230 away from the second base 210 is protruded relative to the surface of the second stopper 240 away from the second base 210, so as to avoid the second stopper 240 affecting the cutting of the trimming piece by the cutting blade 230, thereby ensuring the reliability of the use of the cutting blade 230. Exemplarily, there are multiple second stoppers 240. Multiple second stoppers 240 are arranged at intervals. In addition, when the second trimming module 200 is molded with the first trimming module 100, the outer peripheral surface of the cutting blade 230 is also abutted against the inner peripheral surface of the first stopper 130.
[0064] It can be understood that, during the trimming process, the first stop member 130 and the second stop member 240 can prevent the multiple sub-cutters 232 in the cutting member 230 from generating lateral force, and prevent the multiple sub-cutters 232 of the cutting member 230 from being laterally unloaded, thereby avoiding the trimming mold 500 from being bitten during the trimming process, and ensuring that the edge of the product obtained after the trimming part is trimmed is smooth and beautiful.
[0065] The plurality of second limiting posts 280 and the plurality of second positioning members 290 are all located on the side of the second die base 50 facing the first trimming die set 100, and are all arranged at intervals around the outer peripheral side of the second fixing plate 60. Among them, along the height direction of the trimming die 500, the plurality of second limiting posts 280 are arranged one by one corresponding to the plurality of first limiting posts 160. It can be understood that during the trimming process, when the second trimming die set 200 is molded with the first trimming die set 100, each second limiting post 280 contacts and abuts against a first limiting post 160 to control the downward movement of the second trimming die set 200, so as to prevent the second trimming die set 200 from moving down too much and causing damage to the workpiece or the die.
[0066] In this embodiment, a plurality of second positioning members 290 are arranged in one-to-one correspondence with a plurality of first positioning members 170. Exemplarily, the plurality of second positioning members 290 are all outer guide sleeves. It is understandable that during the trimming process, when the second trimming module 200 is molded with the first trimming module 100, each second positioning member 290 is in contact with and abuts against a first positioning member 170 to play a positioning and guiding role, so that the second trimming module 200 can be aligned with the first trimming module 100, ensuring that the trimming mold 500 has a high trimming accuracy for the sheet metal. In some other embodiments, the plurality of second positioning members 290 can also be outer guide pillars.
[0067] In this embodiment, before the trimming die 500 is used to trim the trimming piece, the second trimming die set 200 is spaced apart from the first trimming die set 100 along the height direction of the trimming die 500 (Z-axis direction in the figure). At this time, the trimming piece to be trimmed can be placed on the support surface 121 of the support member 120 in the first trimming die set 100 by a manipulator, and the trimming piece to be trimmed can be limited by the first limit block 191 and the second limit block 192 to ensure that the placement position of the trimming piece to be trimmed is accurate. Subsequently, the production personnel start the pusher 300. Driven by the pusher 300, the second trimming die set 200 moves relative to the support frame 400 of the trimming machine 1000 along the height direction of the trimming die 500, toward the direction close to the first trimming die set 100. When the pressing plate 220 has not yet contacted the trimming piece to be trimmed, the pressing plate 220 is clamped on the skirt of the fastener 260, and the pressing plate 220 and the elastic member 270 do not interact with each other. As the second trimming module 200 continues to move toward the first trimming module 100 , the pressing plate 220 abuts against the workpiece to be trimmed. At this time, the pressing plate 220 cooperates with the support member 120 to press the workpiece to be trimmed against the support surface 121 of the support member 120 .
[0068] After the trimming piece is pressed, the second trimming module 200 continues to move toward the direction close to the first trimming module 100. At this time, the cutting blade 230 punches the scraps on the outer peripheral side of the trimming piece to obtain the trimming piece and the whole circle of waste pieces. Then, the second trimming module 200 continues to move toward the direction close to the first trimming module 100 and presses down the whole circle of waste pieces. At this time, the whole circle of waste pieces abuts against the multiple waste knives 140. Under the interaction force between the cutting blade 230 and the multiple waste knives 140, the whole circle of waste pieces is cut into multiple waste segments. Then, the plurality of waste segments can be directly fed into the waste bin from the discharge hole 111, or can slide into the guide groove 151 of the discharge member 150 through the discharge slot 112, and then slide out of the trimming die 500 through the guide outlet 1511 of the guide groove 151, and then enter the waste bin through the conveyor belt, so that the trimming die 500 can discharge the waste from the side and bottom. In this process, the pressing plate 220 moves relative to the second fixed plate 60 along the height direction of the trimming die 500 (Z-axis direction in the figure) toward the second fixed plate 60. At this time, the pressing plate 220 squeezes the elastic member 270. The elastic member 270 deforms to generate an elastic force, and the reaction force of the elastic force acts on the pressing plate 220, thereby providing the pressing plate 220 with a force to press the trimming member. Since the second trimming module 200 is provided with a plurality of elastic members 270 arranged at intervals, when the reaction forces of the plurality of elastic forces act on the pressing plate 220, the pressing plate 220 can maintain force balance, so that the pressing plate 220 can evenly press the workpiece to be trimmed.
[0069] When the second limiting column 280 contacts and abuts against the first limiting column 160, the second trimming module 200 and the first trimming module 100 are molded together, and the trimming process is completed. At this time, the operator starts the push member 300 again, and the push member 300 drives the second trimming module 200 to move relative to the support frame 400 in a direction away from the first trimming module 100. During this process, the pressing plate 220 leaves the trimming piece. At this time, the production staff can smoothly take out the trimming piece by a robot or manually, so that the trimming piece and the waste can be directly separated, which helps to speed up the production rhythm and improve the work efficiency of the production staff.
[0070] In the trimming die 500 provided by the present application, by setting a discharge hole 111 on the first base 110 of the first trimming module 100, the waste pieces obtained after the trimming process of the trimming pieces can directly fall into the waste bin through the discharge hole 111, while the trimming pieces are still placed on the support 120, and there is no need for production personnel to manually separate the trimming pieces from the waste pieces, which helps to speed up the production rhythm, improve the work efficiency of production personnel, and ensure a high output rate of the factory. On this basis, by setting a discharge trough 112 on the first base 110, the waste pieces can slide out of the trimming die 500 from the discharge trough 112 after segmentation, and can be transported to the waste bin via a conveyor belt, and the trimming pieces and the waste pieces can also be automatically separated, which can further speed up the production rhythm and improve the work efficiency of production personnel.
[0071] At the same time, the trimming die 500 provided by the present application has fewer parts and a simple and stable structure. On the one hand, it can shorten the development and design cycle and reduce production costs. On the other hand, the parts in the trimming die 500 are mostly installed in an inlay manner, which is convenient for production personnel to disassemble and maintain the parts in the trimming die 500. In addition, the trimming die 500 can be compatible with automated production lines, using manipulators and conveyor belts to pick up and put down materials, which is convenient for picking up and putting down parts, and can lay a good foundation for the subsequent stamping automation structure design, thereby also helping to speed up the production cycle and improve production efficiency.
