Technical Field

[0001] The invention relates to the technical field of stamping equipment, in particular to a metal stamping die which is chip-proof and can be ejected. Background Art

[0002] Hardware: Traditional hardware products, also known as "small hardware". Refers to five metals: gold, silver, copper, iron, and tin. Hardware in modern society is more extensive, such as hardware tools, hardware parts, daily hardware, construction hardware, and security products. When processing hardware materials, stamping dies are often required. Stamping dies are a special process equipment used to process materials into parts during cold stamping. They are called cold stamping dies, also called cold stamping dies. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] At present, the transmission metal stamping die will be affected by the stamping vibration during stamping, which makes the movable die run not smoothly, resulting in the mold closing between the movable die and the fixed die not smooth enough, and affects the overall stamping quality of the product, which is not convenient for subsequent use. Summary of the invention

[0004] To achieve the above purpose, the present invention is implemented by the following technical scheme: a metal stamping die with anti-chip ejection, comprising:

[0005] A frame, wherein a support column is fixedly installed at the side of the outer side of the frame, and a connecting plate is fixedly installed on the top of the support column;

[0006] A movable die mechanism, which is used to adjust the position of the punching tool and punch the metal blank, and is installed in the middle of the bottom of the connecting plate;

[0007] The movable mold mechanism comprises a cylinder and an upper mold plate, wherein the cylinder is installed in the middle of the top of the connecting plate, the telescopic end of the cylinder extends to the bottom of the connecting plate, the top of the upper mold plate is fixedly installed with the telescopic end of the cylinder, punches are installed at positions corresponding to the bottom of the upper mold plate, a reinforcing rod is fixedly installed at the side of the outer side of the upper mold plate and close to the support column, an end of the reinforcing rod away from the upper mold plate is slidably installed with the outer cylindrical surface of the support column through a sliding sleeve, a bending pressing piece is fixedly installed at the side of the top of the upper mold plate, and a roller is rotatably installed at the bottom end of the bending pressing piece, and the contraction and extension of the telescopic end of the cylinder can drive the upper mold plate to move up and down, so that the punch will move up and down with the upper mold plate, so that the height of the punch can be adjusted, which is helpful for stamping the hardware blank;

[0008] A fixed die mechanism, which is used to support the metal blank and perform pressure punching, and is installed in the middle of the top of the frame;

[0009] In which, the fixed mold mechanism includes a lower module and a wedge block, the lower module is installed in the middle of the top of the frame, the wedge block is slidably installed with the top of the frame and close to the position of the lower module, a mold cavity is opened in the middle of the top of the lower module, and mold holes are opened at corresponding positions at the bottom of the inner cavity of the mold cavity, and a right-angle rod is slidably installed at the bottom of the inner cavity of the mold cavity and close to the position of the wedge block, and the bottom end of the right-angle rod is fixedly installed between the bottom end of the right-angle rod and the bottom of the wedge block, and a magnetic disk is fixedly installed on the top of the right-angle rod, and a return spring is fixedly installed on the bottom of the magnetic disk and the top of the frame and close to the position of the right-angle rod. By using the support of the right-angle rod, the hardware sheet blank is placed on the top of the magnetic disk, and the magnetic force of the magnetic disk can be used to magnetically attract the hardware sheet blank, and combined with the top of the magnetic disk being lower than the top of the lower module, the hardware sheet blank can be placed inside the mold cavity, so that the hardware sheet blank can be initially limited, and it is not easy to be skewed.

[0010] Preferably, there are four reinforcing rods, and the four reinforcing rods are evenly installed on the sides of the outer side of the upper template and close to the support columns. There are two bending pressing pieces, and the two bending pressing pieces are symmetrically installed along the upper template. As the upper template moves, the reinforcing rods can be driven by the upper template to move together, and under the guidance of the support columns, the reinforcing rods can provide sliding support for the upper template, so that the upper template is supported when moving, and the upper template can drive the punch to move smoothly as a whole without shaking.

[0011] Preferably, the punch is installed vertically, and the die hole is opened directly below the punch.

[0012] Preferably, there are two wedge blocks, and the two wedge blocks are symmetrically installed along the lower module, and there are two mold holes, and the two mold holes are symmetrically installed along the wedge blocks.

[0013] As the upper template drives the punch to move downward, the bottom end of the punch contacts the top of the metal sheet blank to be processed. The punch continues to move downward, and the position of the punch corresponds to the position of the die hole, so the metal sheet blank can be punched out. When the punch moves downward, the punched chips continue to move downward along the die hole, making it less likely for chips to jump out, effectively preventing chip jumping.

[0014] Preferably, the right-angle rod passes through the lower module and the frame, the right-angle rod passes through the center of the return spring, and the top of the magnetic disk is lower than the top of the lower module.

[0015] Preferably, a limiting mechanism is installed at the side of the top of the frame and close to the wedge block, and the limiting mechanism includes a linear slide groove and a right-angle slider, the linear slide groove is opened on the outside of the frame and close to the top, the right-angle slider is slidably installed between the linear slide groove and the top of the frame, a cylindrical connecting rod is fixedly installed on the outside of the right-angle slider and close to the top, a cylinder is rotatably installed in the middle of the outside of the cylindrical connecting rod, the cylinder is installed close to the wedge block, and a compression tooth is fixedly installed on the outer circumferential surface of the cylindrical connecting rod and close to the cylinder, and the outside of the compression tooth and close to the wedge A bent top pressure block is fixedly installed at the position of the block, and an elastic sheet is fixedly installed between the outer side of the right-angle slider and the inner wall of the linear slide groove. The roller is used to contact the pressure tooth so that the pressure tooth is subjected to the rolling pressure of the roller. Then, under the support of the cylindrical connecting rod and the sliding of the right-angle slider, the cylinder moves toward the inclined surface close to the wedge block, so that the wedge block is subjected to the downward rolling pressure of the cylinder. Under the sliding connection of the right-angle rod, the magnetic disk and the metal sheet blank to be processed move downward together, and the return spring is compressed, so that the bottom of the metal sheet blank to be processed can be fitted with the bottom of the mold cavity, making the placement more stable.

[0016] Preferably, there are four right-angle sliders, and the four right-angle sliders are evenly installed at the corners of the top of the frame, and the elastic sheet is arc-shaped.

[0017] When the stamping is completed, the telescopic end of the cylinder is tightly contracted to drive the upper template to move upward, so that the bending and pressing parts move upward together, the roller is separated from the pressed teeth, and under the elastic force of the elastic sheet, the right-angle slider drives the cylindrical connecting rod to move in the opposite direction, thereby separating the cylinder from the wedge block, and the rolling force on the wedge block disappears. Under the elastic force of the reset spring, the right-angle rod drives the magnetic disk to move upward, lifting the hardware sheet in the die cavity, and the hardware sheet can be ejected, which is convenient for taking out the hardware sheet after punching and cutting.

[0018] Preferably, the pressure-bearing teeth are installed obliquely, there are two bent top pressure blocks, and the two bent top pressure blocks are installed symmetrically along the cylinder.

[0019] When the cylinder rolls the wedge block, under the connection of the cylindrical connecting rod, the pressure teeth and the bending top pressure block move together to a position close to the metal sheet blank. By utilizing the symmetrical bending top pressure blocks on both sides to move toward each other, the end faces of the bending top pressure blocks can fit with the edges of the metal sheet blank, thereby clamping and fixing the metal sheet blank. The metal sheet blank is not easily offset, which helps to accurately stamp.

[0020] Preferably, a chip removal assembly is installed at the bottom of the frame and near the right-angle rod, and the chip removal assembly includes a U-shaped notch and a connecting pin, the opening of the U-shaped notch opens downward, and the U-shaped notch is opened at the side of the outer side of the frame, the connecting pin is rotatably installed on the inner side surface of the U-shaped notch and close to the bottom position of the frame, and the connecting pin is fixedly installed with a material receiving trough plate at one end away from the inner side surface of the U-shaped notch, and the material receiving trough plate is installed directly below the right-angle rod, and an arc tension spring is fixedly installed between the side of the top of the material receiving trough plate and the bottom of the frame. As the right-angle rod moves downward, the material receiving trough plate can be pressed downward through the bottom of the right-angle rod, and under the rotating connection of the connecting pin, the material receiving trough plate can be rotated counterclockwise to adjust the angle, and the arc tension spring is stretched, so that the material receiving trough plate can be in a horizontal state, so as to receive the debris punched out from the bottom end of the die hole, and it is not easy for the debris to fall randomly.

[0021] Preferably, the material receiving trough plate is installed at an angle, and there are two arc-shaped tension springs, and the two arc-shaped tension springs are installed symmetrically along the central axis in the middle of the material receiving trough plate. As the punching is completed, the right-angle rod moves upward, the pressing force on the material receiving trough plate disappears, and under the elastic tension of the arc-shaped tension spring, the material receiving trough plate rotates clockwise to reset, so that the material receiving trough plate is in a tilted state, and the debris in the material receiving trough plate can be poured out, and the debris can be discharged in time to avoid debris accumulation.

[0022] The present invention provides a metal stamping die that is anti-chipping and can be ejected. It has the following beneficial effects:

[0023] 1. For this anti-chip-jumping and ejectable metal stamping die, the staff turns on the cylinder to work. The contraction and extension of the telescopic end of the cylinder can drive the upper template to move up and down, so that the punch will move up and down with the upper template, and the height of the punch can be adjusted, which is helpful for stamping the metal blank.

[0024] Second, the anti-chip-jumping and ejectable metal stamping die can make the reinforcing rod be driven by the upper template to move with the movement of the upper template, and under the guidance of the support column, the reinforcing rod can provide sliding support for the upper template, so that the upper template is supported when moving, and the upper template can drive the punch to move smoothly as a whole without shaking.

[0025] 3. The anti-chip-jumping and ejectable metal stamping die uses the support of the right-angle rod to place the metal sheet blank on the top of the magnetic disk, and the magnetic force of the magnetic disk can be used to magnetically attract the metal sheet blank. In addition, since the top of the magnetic disk is lower than the top of the lower module, the metal sheet blank can be placed inside the mold cavity, and the metal sheet blank can be initially limited, which makes it less likely to be skewed.

[0026] Fourth, the anti-chip jumping and ejectable metal stamping die, as the upper template drives the punch to move downward, makes the bottom end of the punch contact with the top of the metal sheet blank to be processed, and uses the punch to move downward continuously, and the position of the punch corresponds to the position of the die hole, so that the metal sheet blank can be punched out. When the punch moves downward, the punched debris continues to move downward along the die hole, and chip jumping is not easy to occur, so chip jumping is effectively prevented.

[0027] 5. The anti-chip-jumping and ejectable metal stamping die uses a roller to apply rolling pressure to the pressed teeth. Under the support of the cylindrical connecting rod and by sliding the right-angle slider, the cylinder moves toward the inclined surface close to the wedge block, so that the wedge block is subjected to the downward rolling pressure of the cylinder. Under the sliding connection of the right-angle rod, the magnetic disk and the metal sheet blank to be processed move downward together, and the return spring is compressed, so that the bottom of the metal sheet blank to be processed can be fitted with the bottom of the mold cavity, making the placement more stable.

[0028] 6. The anti-chip-jumping and ejectable metal stamping die utilizes the cylinder telescopic end to contract tightly, which can drive the upper die plate to move upward, so that the bending pressing part moves upward together, the roller is separated from the pressed tooth, and under the elastic force of the elastic sheet, the right-angle slider drives the cylindrical connecting rod to move in the opposite direction, thereby separating the cylinder from the wedge block, and the rolling force on the wedge block disappears. Under the elastic force of the reset spring, the right-angle rod drives the magnetic disk to move upward, lifting the metal sheet in the die cavity, and the metal sheet can be ejected, which is convenient for taking out the metal sheet that has been punched and cut.

[0029] 7. The anti-chip-jumping and ejectable metal stamping die, when the cylinder rolls the wedge-shaped block, the pressure-bearing teeth and the bending top pressure block move together to a position close to the metal sheet blank, and the symmetrical bending top pressure blocks on both sides move toward each other, so that the end faces of the bending top pressure blocks can fit with the edges of the metal sheet blank, thereby clamping and fixing the metal sheet blank, and the metal sheet blank is not easy to deviate, which is conducive to accurate stamping.

[0030] 8. The anti-chip-jumping and ejectable metal stamping die can press the receiving trough plate downward through the bottom of the right-angle rod, and under the rotating connection of the connecting pin, the receiving trough plate is rotated counterclockwise to adjust the angle, and the arc-shaped tension spring is stretched, so that the receiving trough plate can be in a horizontal state, and the debris punched out from the bottom of the die hole can be received, and the debris is not likely to fall randomly.

[0031] 9. The anti-chip-jumping and ejectable hardware stamping die, as the punching is completed, the right-angle rod moves upward, the pressing force on the material receiving trough plate disappears, and under the elastic tension of the arc-shaped tension spring, the material receiving trough plate rotates clockwise to reset, so that the material receiving trough plate is in an inclined state, and the debris in the material receiving trough plate can be poured out, and the chips can be removed in time to avoid debris accumulation.

[0042] The first embodiment, as Figure 1-Figure 5 As shown, the present invention provides a technical solution: a metal stamping die that can prevent chip jumping and can be ejected, comprising:

[0043] A frame 1, a support column 2 is fixedly installed on the side of the outer side of the frame 1, and a connecting plate 3 is fixedly installed on the top of the support column 2;

[0044] A movable die mechanism 4, which is used to adjust the position of the punching tool and punch the metal blank, and is installed in the middle of the bottom of the connecting plate 3;

[0045] The movable mold mechanism 4 includes a cylinder 41 and an upper mold plate 42. The cylinder 41 is installed in the middle of the top of the connecting plate 3. The telescopic end of the cylinder 41 extends to the bottom of the connecting plate 3. The top of the upper mold plate 42 is fixedly installed with the telescopic end of the cylinder 41. Punches 43 are installed at the corresponding positions of the bottom of the upper mold plate 42. A reinforcing rod 44 is fixedly installed at the side of the outer side of the upper mold plate 42 and close to the support column 2. The end of the reinforcing rod 44 away from the upper mold plate 42 is slidably installed with the outer cylindrical surface of the support column 2 through a sliding sleeve. A bending pressing piece 45 is fixedly installed at the side of the top of the upper mold plate 42. A roller 46 is rollingly installed at the bottom end of the bending pressing piece 45. The staff turns on the cylinder 41 to work. The contraction and extension of the telescopic end of the cylinder 41 can drive the upper mold plate 42 to move upward and downward, so that the punch 43 will move up and down with the upper mold plate 42, so that the height of the punch 43 can be adjusted.

[0046] There are four reinforcing rods 44 , and the four reinforcing rods 44 are evenly installed at the sides of the outer side of the upper template 42 and close to the support column 2 . There are two bending pressing pieces 45 , and the two bending pressing pieces 45 are symmetrically installed along the upper template 42 .

[0047] As the upper template 42 moves, the reinforcing rod 44 can be driven by the upper template 42 to move together, and under the guidance of the support column 2, the reinforcing rod 44 can provide sliding support for the upper template 42, so that the upper template 42 is supported when moving, and the upper template 42 can drive the punch 43 to move smoothly as a whole.

[0048] The punch 43 is installed vertically, and the die hole 54 is opened directly below the punch 43 .

[0049] A fixed die mechanism 5, which is used to support the metal blank and perform pressure punching, and is installed in the middle of the top of the frame 1;

[0050] The fixed mold mechanism 5 includes a lower mold block 51 and a wedge block 52. The lower mold block 51 is installed in the middle of the top of the frame 1. The wedge block 52 is slidably installed at the top of the frame 1 and close to the lower mold block 51. A mold cavity 53 is opened in the middle of the top of the lower mold block 51. The corresponding positions of the bottom of the inner cavity of the mold cavity 53 are opened with mold holes 54. A right-angle rod 55 is slidably installed at the bottom of the inner cavity of the mold cavity 53 and close to the position of the wedge block 52. The bottom end of the right-angle rod 55 is fixedly installed between the bottom of the wedge block 52. A magnetic disk 56 is fixedly installed on the top of the rod 55, and a return spring 57 is fixedly installed on the bottom of the magnetic disk 56 and the top of the frame 1 and close to the right-angle rod 55. With the support of the right-angle rod 55, the hardware sheet blank is placed on the top of the magnetic disk 56, and the magnetic force of the magnetic disk 56 can be used to magnetically attract the hardware sheet blank. In addition, since the top of the magnetic disk 56 is lower than the top of the lower module 51, the hardware sheet blank can be placed inside the mold cavity 53, and the hardware sheet blank can be preliminarily limited.

[0051] There are two wedge blocks 52 , and the two wedge blocks 52 are symmetrically installed along the lower die block 51 . There are two die holes 54 , and the two die holes 54 are symmetrically installed along the wedge blocks 52 .

[0052] As the upper template 42 drives the punch 43 to move downward, the bottom end of the punch 43 contacts the top of the metal sheet blank to be processed. The punch 43 continues to move downward, and the position of the punch 43 corresponds to the position of the die hole 54, so the metal sheet blank can be punched. When the punch 43 moves downward, the punched chips continue to move downward along the die hole 54, and chip jumping is less likely to occur.

[0053] The right-angle rod 55 passes through the lower module 51 and the frame 1 . The right-angle rod 55 passes through the center of the return spring 57 . The top of the magnetic disk 56 is lower than the top of the lower module 51 .

[0054] The second embodiment, as Figure 1-Figure 7 As shown, based on the first embodiment:

[0055] A limiting mechanism 6 is installed at the side of the top of the frame 1 and close to the wedge block 52. The limiting mechanism 6 includes a linear slide 61 and a right-angle slider 62. The linear slide 61 is opened on the outside of the frame 1 and close to the top. The right-angle slider 62 is slidably installed between the linear slide 61 and the top of the frame 1. A cylindrical connecting rod 63 is fixedly installed on the outside of the right-angle slider 62 and close to the top. A cylinder 64 is rollingly installed in the middle of the outside of the cylindrical connecting rod 63. The cylinder 64 is installed near the wedge block 52. A pressure tooth 65 is fixedly installed on the outer circumferential surface of the cylindrical connecting rod 63 and close to the cylinder 64. A bent top pressure block 66 is fixedly installed on the outside of the pressure tooth 65 and close to the wedge block 52. The right-angle slider An elastic sheet 67 is fixedly installed between the outer side of 62 and the inner wall of the linear slide groove 61. When the upper template 42 moves downward, it can drive the bending pressing piece 45 to move downward, and utilize the roller 46 to contact the pressure-bearing tooth 65, so that the pressure-bearing tooth 65 is subjected to the rolling force of the roller 46. Then, under the support of the cylindrical connecting rod 63 and by utilizing the sliding of the right-angle slider 62, the cylinder 64 moves toward the inclined surface close to the wedge block 52, so that the wedge block 52 is subjected to the downward rolling force of the cylinder 64, and under the sliding connection of the right-angle rod 55, the magnetic disk 56 and the metal sheet blank to be processed move downward together, and the return spring 57 is compressed, so that the bottom of the metal sheet blank to be processed can be fitted with the bottom of the mold cavity 53, making the placement more stable.

[0056] There are four right-angle sliders 62 , and the four right-angle sliders 62 are evenly installed at the corners of the top of the frame 1 , and the elastic sheet 67 is arc-shaped.

[0057] When the stamping is completed, the telescopic end of the cylinder 41 is tightly contracted to drive the upper template 42 to move upward, so that the bending pressing piece 45 moves upward together, the roller 46 is separated from the pressure tooth 65, and under the elastic force of the elastic sheet 67, the right-angle slider 62 drives the cylindrical connecting rod 63 to move in the opposite direction, so that the cylinder 64 is separated from the wedge block 52, and the rolling force on the wedge block 52 disappears. Under the elastic force of the reset spring 57, the right-angle rod 55 drives the magnetic disk 56 to move upward, and the metal sheet in the mold cavity 53 is lifted up, so that the metal sheet can be ejected.

[0058] The pressure-bearing tooth 65 is installed at an angle, and there are two bent top pressure blocks 66, and the two bent top pressure blocks 66 are installed symmetrically along the cylinder 64. When the cylinder 64 rolls the wedge block 52, under the connection of the cylindrical connecting rod 63, the pressure-bearing tooth 65 and the bent top pressure block 66 move together to a position close to the metal sheet blank. By utilizing the symmetrical bent top pressure blocks 66 on both sides to move toward each other, the end faces of the bent top pressure blocks 66 can be fitted with the edges of the metal sheet blank, thereby clamping and fixing the metal sheet blank.

[0059] The third embodiment, as Figure 1-Figure 8As shown, based on the first and second embodiments:

[0060] A chip removal assembly 7 is installed at the bottom of the frame 1 and near the right-angle rod 55. The chip removal assembly 7 includes a U-shaped notch 71 and a connecting pin 72. The opening of the U-shaped notch 71 is downward, and the U-shaped notch 71 is opened at the side of the outer side of the frame 1. The connecting pin 72 is rotatably installed on the inner side of the U-shaped notch 71 and near the bottom of the frame 1. A material receiving trough plate 73 is fixedly installed at one end of the connecting pin 72 away from the inner side of the U-shaped notch 71. The material receiving trough plate 73 is installed on the right-angle rod 5 5, an arc-shaped tension spring 74 is fixedly installed between the side of the top of the material receiving trough plate 73 and the bottom of the frame 1. As the right-angle rod 55 moves downward, the material receiving trough plate 73 can be pressed downward through the bottom of the right-angle rod 55, and under the rotation connection of the connecting pin 72, the material receiving trough plate 73 is rotated counterclockwise to adjust the angle, and the arc-shaped tension spring 74 is stretched, so that the material receiving trough plate 73 can be in a horizontal state to receive the debris punched out from the bottom end of the die hole 54.

[0061] The material receiving trough plate 73 is installed at an angle, and there are two arc-shaped tension springs 74, and the two arc-shaped tension springs 74 are installed symmetrically along the central axis in the middle of the material receiving trough plate 73. As the punching is completed, the right-angle rod 55 moves upward, the pressing force on the material receiving trough plate 73 disappears, and under the elastic tension of the arc-shaped tension spring 74, the material receiving trough plate 73 rotates clockwise to reset, so that the material receiving trough plate 73 is in a tilted state, and the debris in the material receiving trough plate 73 can be poured out.

[0062] When in use, first place the metal sheet blank on the top of the magnetic disk 56, and then the magnetic force of the magnetic disk 56 can be used to magnetically attract the metal sheet blank. In addition, since the top of the magnetic disk 56 is lower than the top of the lower module 51, the metal sheet blank can be placed inside the mold cavity 53, and the metal sheet blank can be initially limited.

[0063] The staff starts the cylinder 41 to work, and the extension of the telescopic end of the cylinder 41 can drive the upper template 42 to move downward, so that the punch 43 moves up and down with the upper template 42, and the height of the punch 43 can be adjusted;

[0064] As the upper template 42 moves, the reinforcing rod 44 can be driven by the upper template 42 to move together, and under the guidance of the support column 2, the reinforcing rod 44 can slide and support the upper template 42, so that the upper template 42 is supported when moving, and the upper template 42 can drive the punch 43 to move smoothly as a whole;

[0065] The roller 46 is in contact with the pressure-receiving tooth 65, so that the pressure-receiving tooth 65 is subjected to the rolling force of the roller 46. Then, under the support of the cylindrical connecting rod 63 and by the sliding of the right-angle slider 62, the cylinder 64 moves toward the inclined surface close to the wedge block 52, so that the wedge block 52 is subjected to the downward rolling force of the cylinder 64. Under the sliding connection of the right-angle rod 55, the magnetic disk 56 and the metal sheet blank to be processed move downward together, and the return spring 57 is compressed, so that the bottom of the metal sheet blank to be processed can be fitted with the bottom of the mold cavity 53, so that the placement is more stable.

[0066] At the same time, when the cylinder 64 rolls the wedge block 52, under the connection of the cylindrical connecting rod 63, the pressure teeth 65 and the bending top pressing block 66 move together to a position close to the metal sheet blank, and the bending top pressing blocks 66 on both sides move symmetrically toward each other, so that the end surface of the bending top pressing block 66 can fit with the edge of the metal sheet blank, thereby clamping and fixing the metal sheet blank;

[0067] As the right-angle rod 55 moves downward, the bottom of the right-angle rod 55 can press the material receiving groove plate 73 downward, and under the rotation connection of the connecting pin 72, the material receiving groove plate 73 is rotated counterclockwise to adjust the angle, and the arc-shaped tension spring 74 is stretched, so that the material receiving groove plate 73 is in a horizontal state;

[0068] As the upper mold plate 42 drives the punch 43 to move downward, the bottom end of the punch 43 contacts the top of the metal sheet blank to be processed. The punch 43 continues to move downward, and the position of the punch 43 corresponds to the position of the die hole 54, so that the metal sheet blank can be punched. When the punch 43 moves downward, the punched chips continue to move downward along the die hole 54, and the chip jumping is not easy to occur. At this time, the horizontal receiving groove plate 73 receives the chips.

[0069] When the stamping is completed, the telescopic end of the cylinder 41 is tightly contracted to drive the upper mold plate 42 to move upward, so that the bending pressing piece 45 moves upward together, and the roller 46 is separated from the pressure-bearing tooth 65. Under the elastic force of the elastic sheet 67, the right-angle slider 62 drives the cylindrical connecting rod 63 to move in the opposite direction, so that the cylinder 64 is separated from the wedge block 52, and the rolling force on the wedge block 52 disappears. Under the elastic force of the reset spring 57, the right-angle rod 55 drives the magnetic disk 56 to move upward, and the metal sheet in the mold cavity 53 is lifted up, so that the metal sheet can be ejected;

[0070] Moreover, as the punching is completed, the right-angle rod 55 moves upward, the pressing force on the material receiving trough plate 73 disappears, and under the elastic tension of the arc-shaped tension spring 74, the material receiving trough plate 73 rotates clockwise to reset, so that the material receiving trough plate 73 is in a tilted state, and the debris in the material receiving trough plate 73 can be poured out.
