[0002] In the metal processing industry, punch presses are an important piece of equipment that is widely used in the stamping process of various metal materials. The working principle of a punch press is to apply huge pressure to cause the metal material to undergo plastic deformation under the action of the die, thereby obtaining the desired shape and size.

[0003] Punching machine is a common metal processing equipment, widely used in the fields of mechanical parts manufacturing. It applies huge pressure to materials such as metal sheets to make them plastically deform, thereby realizing various processing technologies such as punching, blanking, bending, and stretching. In the manufacturing of mechanical parts, the high precision, high efficiency, and high stability of the punching machine are crucial to ensure the quality and production efficiency of the parts.

[0004] At present, when the existing mechanical parts manufacturing punch press is punching the metal sheet, the metal sheet is punched by a hydraulic press. In order to prevent the debris generated by the punching from splashing outward and causing harm to the workers, the manufacturing punch press uses a protective mechanism to block the debris during the punching process.

The staff places the sheet on top of the stabilizing assembly, presses the fitting clip according to the thickness of the sheet, so that the fitting clip fits on top of the sheet, and positions both sides of the sheet to prevent the sheet from warping up at both ends due to stamping, causing the sheet to bend and deform under force.

[0007] Preferably, the fitting clamp comprises a frame shell, an extrusion piece is fixedly installed between opposite surfaces of the frame shell, a pressing plate is fixedly installed on the outer surface of the extrusion piece, connecting blocks are fixedly installed on both sides of the outer surface of the pressing plate, and a cross plate is slidably installed between opposite surfaces of the frame shell away from the extrusion piece.

[0008] Preferably, a round rod is fixedly installed at the middle of the outer surface of the transverse plate, a fixing frame is fixedly installed on the outer surface of the round rod, and a curved pad is movably installed at the bottom of the fixing frame.

The staff pushes the pressing sheet to cause the pressing sheet to extrude the extrusion piece, so that the spring sheet and the bending rod are deformed by force, and the deformed pressing sheet drives the connecting block and the cross plate to slide and displace in the frame shell as the deformation occurs, so that the round rod connected to the surface of the cross plate is pulled, so that the arc pad is pulled to change the curvature, so that it fits on the surface of the material plate, so as to fit and limit the two sides of the material plate, and improve the stability of the material plate during stamping.

[0011] Preferably, the stabilizing assembly includes an operating plate, a support pad is fixedly installed on the top of the operating plate, two support pads are provided, and the two support pads are symmetrically arranged with the support pad as the center, and a positioning plate is fixedly installed on the top of the support pad, and a through groove is opened on the surface of the positioning plate. The staff starts the hydraulic press, so that the hydraulic press drives the stamping assembly downward to stamp the material plate, and the material plate is forced to squeeze the buffer, so that the buffer is deformed by the force, so as to buffer the force point at the bottom of the material plate, so as to prevent the material plate from being overstressed and affecting the stamping accuracy of the mechanical parts.

[0013] Preferably, the buffer comprises a bottom bar, and bent bars are fixedly mounted on both sides of the outer surface of the bottom bar, and the bent bars extend through the positioning plate to the top thereof, and a connecting block is fixedly mounted on the top of the bent bars. The material sheet is placed above the support plate, and when the material sheet is stamped, the bent pad is forced to be squeezed with the operating plate, and at this time, the segmented bent pad is forced to deform and extend outward, so as to avoid shaking of the material sheet during stamping, and to avoid deformation of the material sheet due to excessive force during stamping.

[0014] Preferably, a semicircular cover is fixedly installed on the top of the bottom rod, a round block is fixedly installed on the top of the semicircular cover, a bent pad is fixedly installed on the outer surface of the semicircular cover, and a connecting plate is fixedly installed on the outer surface of the bent pad.

[0015] Preferably, the round block is fixedly mounted inside the slot, the bottom rod is fixedly mounted on both sides of the bottom of the support plate, and the bent pad is squeezed and adapted to the support plate. When the operating panel is squeezed, the slot is squeezed downward by force, and at this time, the semicircular cover transmits the pressure to the connecting plate and the surface of the bent pad, so that the connecting plate, the bent pad and the support plate are squeezed. Since the bent pad is set to a rubber flexible material, it will deform and extend outward when squeezed, thereby driving the operating panel to slide down in the through slot, and multiple groups of bent pads can maintain the stability of the operating panel when it descends, and prevent the operating panel from tilting.

[0016] The present invention provides a punching machine for manufacturing mechanical parts with a protective mechanism. It has the following beneficial effects: 1. The mechanical parts manufacturing punching machine with a protective mechanism has a staff placing the mechanical parts material plate above the stabilizing support component and adjusting the position between the clamping component and the material plate to position and balance the two sides of the material plate. Then the staff starts the hydraulic press to drive the stamping component downward to stamp the material plate. When the stamping component stamps the material plate, the stabilizing support component is squeezed and depressed downward to buffer the pressure generated by the stamping component. The protective door arranged on the outside of the positioning frame protects the debris generated by the stamping to avoid the debris splashing and causing harm to the staff.

[0017] 2. The punch press for manufacturing mechanical parts with a protective mechanism has a staff placing the material plate on top of the stabilizing component. The staff presses the fitting clamp according to the thickness of the material plate so that the fitting clamp fits on top of the material plate and positions both sides of the material plate to prevent the material plate from warping up at both ends due to stamping, causing the material plate to bend and deform under force.

[0018] 3. The punch press for manufacturing mechanical parts with a protective mechanism, through the staff pushing the pressing plate, makes the pressing plate squeeze the extrusion part, so that the spring sheet and the bending rod are deformed by force, and at this time, the pressing plate that is pressed and displaced drives the connecting block and the cross plate to slide and displace in the frame shell as the deformation occurs, so that the round rod connected to the surface of the cross plate is pulled, so that the bending pad is pulled to change the curvature, so that it fits on the surface of the material plate, so as to fit and limit the two sides of the material plate, and improve the stability of the material plate during stamping.

[0019] 4. The punch press for manufacturing mechanical parts with a protective mechanism is started by a staff member, so that the hydraulic press drives the stamping assembly downward to stamp the material plate. The material plate is forced to squeeze the buffer part, causing the buffer part to deform under the force, so as to buffer the force point at the bottom of the material plate, thereby preventing the material plate from being subjected to excessive force and affecting the stamping accuracy of the mechanical parts.

[0020] 5. The punch press for manufacturing mechanical parts with a protective mechanism is placed above the support plate through the material plate. When the material plate is punched, the bending pad is forced to squeeze the operating plate. At this time, the segmented bending pad is forced to deform and extend outward to avoid shaking of the material plate during punching, so as to avoid deformation of the material plate due to excessive force during punching. When the operating plate is squeezed, the card slot is forced to squeeze downward. At this time, the semicircular cover transmits the pressure to the connecting plate and the surface of the bending pad, so that the connecting plate, the bending pad and the support plate are squeezed. Since the bending pad is set to a flexible rubber material, it will deform and extend outward when squeezed, thereby driving the operating plate to slide down in the through groove, and multiple groups of bending pads can maintain the stability of the operating plate when it descends, to avoid the operating plate from tilting.

The staff places the sheet on top of the stabilizing assembly 8, presses the fitting clip 72 according to the thickness of the sheet, so that the fitting clip 72 fits on the top of the sheet, and positions both sides of the sheet to prevent the sheet from warping upward at both ends due to stamping, causing the sheet to bend and deform under force.

[0026] The bonding clamp 72 includes a frame shell 724, an extrusion piece 728 is fixedly installed between the opposite surfaces of the frame shell 724, a pressing plate 722 is fixedly installed on the outer surface of the extrusion piece 728, connecting blocks 726 are fixedly installed on both sides of the outer surface of the pressing plate 722, and a horizontal plate 723 is slidably installed between the opposite surfaces of the frame shell 724 away from the extrusion piece 728.

[0027] A round rod 727 is fixedly installed at the middle of the outer surface of the horizontal plate 723 , a fixing frame 725 is fixedly installed on the outer surface of the round rod 727 , and a curved pad 721 is movably installed at the bottom of the fixing frame 725 .

[0029] A sliding roller 7283 is fixedly mounted on the surface of the middle plate 7282 , and a bent piece 7285 is fixedly mounted on the outer surface of the sliding roller 7283 . The bent piece 7285 is fixedly connected to the spring piece 7281 .

[0030] The third embodiment is based on the first and second embodiments. Figures 8 to 10 As shown, the stabilizing assembly 8 includes an operating plate 82, a support pad 87 is fixedly installed on the top of the operating plate 82, two support pads 87 are provided, and the two support pads 87 are symmetrically arranged with the support pad 87 as the center, and a positioning plate 83 is fixedly installed on the top of the support pad 87, and a through groove 85 is opened on the surface of the positioning plate 83. The staff starts the hydraulic press 1, so that the hydraulic press 1 drives the stamping assembly 2 downward to stamp the material plate, and the material plate is forced to squeeze the buffer 84, so that the buffer 84 is deformed by the force, so as to buffer the force point at the bottom of the material plate, and prevent the material plate from being overstressed and affecting the stamping accuracy of the mechanical parts.

[0031] A buffer member 84 is fixedly installed inside the through groove 85 , and a support plate 81 is fixedly installed on the top of the buffer member 84 . Two support plates 81 are provided, and slots 86 are opened on both sides of the outer surfaces of the two support plates 81 . The support plates 81 are fixedly connected to the buffer member 84 via the slots 86 .

[0032] The buffer member 84 includes a bottom rod 844, and bent rods 842 are fixedly installed on both sides of the outer surface of the bottom rod 844. The bent rods 842 penetrate the positioning plate 83 and extend to the top thereof, and a connecting block 841 is fixedly installed on the top of the bent rod 842. The material sheet is placed above the support plate 81. When the material sheet is stamped, the bent pads 843 are forced to be squeezed with the operating plate 82. At this time, the segmented bent pads 843 are forced to deform and extend outward to prevent the material sheet from shaking during stamping, and to prevent the material sheet from being deformed due to excessive force during stamping.

[0033] A semicircular cover 845 is fixedly installed on the top of the bottom rod 844 , a round block 847 is fixedly installed on the top of the semicircular cover 845 , a bent pad 843 is fixedly installed on the outer surface of the semicircular cover 845 , and a connecting plate 846 is fixedly installed on the outer surface of the bent pad 843 .

When the operation panel 82 is squeezed, the slot 86 is forced to squeeze downward, and at this time, the semicircular cover 845 transmits the pressure to the surface of the connecting plate 846 and the bent pad 843, so that the connecting plate 846, the bent pad 843 and the support plate 81 are squeezed. Since the bent pad 843 is set to a rubber flexible material, it will deform and extend outward when squeezed, thereby driving the operation panel 82 to slide down in the through slot 85, and the multiple groups of bent pads 843 can maintain the stability of the operation panel 82 when it descends, and prevent the operation panel 82 from tilting.

[0035] When in use, the staff will place the mechanical accessory sheet above the stabilizing component 8 and adjust the position between the clamping component 7 and the sheet to position and balance the two sides of the sheet. Then the staff will start the hydraulic press 1, so that the hydraulic press 1 drives the stamping component 2 downward to stamp the sheet. When the stamping component 2 stamps the sheet, the stabilizing component 8 is squeezed and depressed downward to buffer the pressure generated by the stamping component 2. The protective door 3 arranged on the outside of the positioning frame 5 protects against the debris generated by the stamping to avoid the debris splashing and causing harm to the staff.

[0036] The staff places the material sheet on top of the stabilizing assembly 8, and presses the fitting clamp 72 according to the thickness of the material sheet so that the fitting clamp 72 fits on top of the material sheet, and positions both sides of the material sheet to prevent the material sheet from warping up at both ends due to stamping, causing the material sheet to bend and deform under force.

[0037] The staff pushes the pressing piece 722 so that the pressing piece 722 squeezes the extrusion piece 728, so that the spring piece 7281 and the bending rod 7284 are deformed by force. At this time, the pressing and displaced pressing piece 722 drives the connecting block 726 and the cross plate 723 to slide and displace in the frame shell 724 as they are deformed, so that the round rod 727 connected to the surface of the cross plate 723 is pulled, so that the bending pad 721 is pulled to change the curvature, so that it fits on the surface of the material plate, so as to fit and limit the two sides of the material plate, thereby improving the stability of the material plate during stamping.

[0038] The staff starts the hydraulic press 1, so that the hydraulic press 1 drives the stamping assembly 2 downward to stamp the material plate. The material plate is forced to squeeze the buffer 84, causing the buffer 84 to deform under the force to buffer the force point at the bottom of the material plate to prevent the material plate from being subjected to excessive force and affecting the stamping accuracy of the mechanical parts.

[0039] The material sheet is placed above the support plate 81. When the material sheet is stamped, the bending pad 843 is subjected to force and squeezed with the operating plate 82. At this time, the segmented bending pad 843 is deformed and extended outward to avoid shaking of the material sheet during stamping, so as to avoid deformation of the material sheet due to excessive force during stamping.

[0040] When the operating panel 82 is squeezed, the slot 86 is squeezed downward. At this time, the semicircular cover 845 transmits the pressure to the surface of the connecting plate 846 and the bending pad 843, so that the connecting plate 846, the bending pad 843 and the support plate 81 are squeezed. Since the bending pad 843 is set to a flexible rubber material, it will deform and extend outward when squeezed, thereby driving the operating panel 82 to slide down in the through slot 85, and multiple groups of bending pads 843 can maintain the stability of the operating panel 82 when it descends, and prevent the operating panel 82 from tilting.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
