Description

Technical Field

[0001] This utility model relates to the field of hardware stamping machine technology, specifically a hardware stamping machine for preventing workpiece displacement. Background Technology

[0002] Metal stamping machines are a technology for processing metal sheets into specific shapes. They play an important role in the manufacturing of lighting accessories. Metal stamping machines can punch and die-cast metal sheets for lighting accessories, and stamp and die-cast the metal sheets into specified shapes and sizes to meet the subsequent installation requirements of light bulbs. However, existing metal stamping machines still have certain defects in use.

[0003] In existing technology, metal stamping machines use punches of specific shapes to punch holes in metal sheets. The size of the holes can be selected according to the actual situation by choosing different sizes of stamping seats and stamping heads for stamping and die casting operations. During the continuous stamping process, the metal sheet of the lamp needs to be continuously pushed by personnel. When personnel push the metal sheet, the position of the metal sheet will be greatly offset, resulting in deviation of the punching position, which will affect the subsequent installation of the bulb. Utility Model Content

[0004] The purpose of this utility model is to provide a metal stamping machine that prevents workpiece displacement, so as to solve the problem mentioned in the background art that the current metal stamping machines on the market are not easy to limit and guide the workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal stamping machine for preventing workpiece displacement, comprising: a stamping machine body, a stamping seat, a controller, a hydraulic push rod, and a stamping head. The stamping seat is mounted on the surface of the stamping machine body. The controller is mounted on the front of the stamping machine body. A hydraulic push rod is mounted on the top of the stamping machine body. A stamping head is mounted on the bottom end of the hydraulic push rod. An mounting block is mounted on the surface of the stamping machine body near the stamping seat. A guide rod is connected to the top of the mounting block. A double-acting screw is connected to the inside of the mounting block via a bearing. A moving plate is threaded to the outer side of the double-acting screw. A U-shaped seat is connected to one side of the two moving plates facing each other. A threaded column is threaded to the inside of the U-shaped seat. A limit block is connected to the bottom of the threaded column. A connecting rod is welded to the inner side of the U-shaped seat. A rotating column is rotatably connected to the outer side of the connecting rod.

[0006] Preferably, two sets of mounting blocks are arranged symmetrically about the center of the stamping seat.

[0007] Preferably, the movable plate and the guide rod form a sliding structure.

[0008] Preferably, a fixed seat is connected to the outer side of the main body of the stamping machine, a connecting shaft is connected inside the fixed seat, and a support plate is rotatably connected to the outer side of the connecting shaft.

[0009] Preferably, a support frame is connected to the surface of the support plate, a rotating shaft is connected to the bottom of the support plate, and a support rod is rotatably connected to the outside of the rotating shaft.

[0010] Preferably, an L-shaped connecting block is welded to the end of the support rod, and a fixing block is welded to the outer side of the main body of the stamping machine near the L-shaped connecting block.

[0011] Preferably, the fixing block and the L-shaped connecting block are both connected by a pin.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the bidirectional lead screw rotates, it can drive two sets of moving plates to slide closer to each other. When the two sets of moving plates move towards each other, they can slide through the guide rod. When the moving plates move, they can drive the U-shaped seat to move. The end of the pin can pass through the fixing block and the L-shaped connecting block. At this time, the pin can limit the L-shaped connecting block, thereby fixing the support plate and the support frame. The support frame can assist in supporting the tail end of the metal plate workpiece, so that the personnel do not need to lift the tail end of the metal plate workpiece for a long time, thereby reducing the labor of the personnel.

[0013] 1. Metal stamping machines are commonly used in the processing of metal sheets for lighting fixtures. Using specified molds, metal stamping machines can perform die-casting on metal materials. By utilizing the specific shape of the mold and the pressure of the stamping machine, the metal material undergoes plastic deformation to obtain the required shape and size. However, when personnel push the metal sheet, significant positional shifts can occur, leading to deviations in the punching position of the workpiece, affecting the subsequent installation and use of the bulb. When the bidirectional lead screw rotates, it can drive two sets of moving plates to slide closer together. When the two sets of moving plates move towards each other, they can slide through the guide rod. Furthermore, the movement of the moving plates can drive the U-shaped seats to move. When the inner sides of all four sets of U-shaped seats have moved to the outer sides of the metal sheet, the two sides of the metal sheet are located inside the four sets of U-shaped seats. When the surface of the rotating column inside the U-shaped seat is... When the distance to the outer side of the metal plate is small, the rotation of the double-acting screw can be stopped. When the threaded column rotates, it can drive the limiting block to rotate and move closer to the metal plate workpiece. When the limiting block moves to a certain distance from the top surface of the metal plate workpiece, the rotation of the threaded column can be stopped. When the personnel push the metal plate workpiece, the metal plate workpiece can be limited by the four sets of rotating columns. At the same time, when the side of the metal plate workpiece contacts the rotating column, it can drive the rotating column to rotate through the connecting rod, so that the rotating column can provide auxiliary guidance for the metal plate workpiece. The limiting block can prevent the workpiece from tilting during the movement. Through the above methods, the metal plate workpiece is less likely to have a large positional deviation during the movement of the personnel pushing the metal plate workpiece, thereby improving the accuracy of the punching position of the metal plate workpiece.

[0014] 2. During the use of a metal stamping machine, the tail end of some long metal sheet workpieces needs to be supported by personnel to prevent it from collapsing. Frequent lifting increases the workload for workers. When the support plate moves, it can rotate via a connecting shaft. When the support plate rotates, it can drive the support frame and rotating shaft to rotate and move. When the support plate rotates to its maximum angle, the support rod can be pushed towards the main body of the stamping machine. When the support rod moves, it can rotate via a rotating shaft. When the support rod rotates, it can drive the L-shaped connecting block to move. When the end of the L-shaped connecting block moves to the position below the fixed block, the pin can be inserted into the fixed block. The end of the pin can pass through the fixed block and the L-shaped connecting block. At this time, the pin can limit the L-shaped connecting block, thereby fixing the support plate and support frame. The support frame can assist in supporting the tail end of the metal sheet workpiece, so that personnel do not need to lift the tail end of the metal sheet workpiece for a long time, thus reducing the workload for workers.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 and Figure 2 It is understood that this utility model provides a technical solution: a metal stamping machine for preventing workpiece displacement, comprising: a stamping machine body 1, a stamping seat 2, a controller 3, a hydraulic push rod 4, and a stamping head 5. The stamping seat 2 is mounted on the surface of the stamping machine body 1. The controller 3 is mounted on the front of the stamping machine body 1. The hydraulic push rod 4 is mounted on the top of the stamping machine body 1. The stamping head 5 is mounted on the bottom end of the hydraulic push rod 4. An mounting block 6 is mounted on the surface of the stamping machine body 1 near the stamping seat 2. A guide rod 7 is connected to the top of the mounting block 6. The mounting block 6 is internally connected to a double-acting lead screw 8 via a bearing. The outer side of the double-acting lead screw 8 is threadedly connected to a movable plate 9. A U-shaped seat 10 is connected to one side of the two movable plates 9 facing each other. A threaded column 11 is threadedly connected to the inside of the U-shaped seat 10. A limit block 12 is connected to the bottom of the threaded column 11. A connecting rod 13 is welded to the inner side of the U-shaped seat 10. A rotating column 14 is rotatably connected to the outer side of the connecting rod 13. The mounting block 6 is symmetrically arranged with two sets of movable plates 9 and guide rods 7 about the center of the stamping seat 2. The movable plates 9 and guide rods 7 form a sliding structure.

[0021] In practical implementation, metal stamping machines are commonly used in the processing of metal sheets for lighting fixtures. Metal stamping machines can perform die-casting on metal materials using specified molds. Utilizing the specific shape of the mold and the pressure of the stamping machine, the metal material undergoes plastic deformation to obtain the required shape and size. Because large positional shifts can easily occur when personnel push the metal sheet, the punching position of the workpiece may deviate, affecting the subsequent installation and use of the bulbs. The metal sheet can be placed in the center of the stamping base 2 first, and then the two sets of bidirectional lead screws 8 can be rotated forward. When the bidirectional lead screws 8 rotate, they can drive the two sets of moving plates 9 to slide closer together. When the two sets of moving plates 9 move towards each other, they can slide through the guide rod 7. Furthermore, the movement of the moving plates 9 can drive the U-shaped seat 10 to move. When the four sets of U-shaped... When the inner side of seat 10 moves to the outer side of the metal plate, the two sides of the metal plate are located inside the four sets of U-shaped seats 10. When the distance between the surface of the rotating column 14 inside the U-shaped seat 10 and the outer side of the metal plate is small, the rotation of the bidirectional lead screw 8 can be stopped. The rotating column 14 does not squeeze the metal plate, and the inner surface of the U-shaped seat 10 is flush with the top surface of the stamping seat 2. At this time, the four sets of rotating columns 14 can limit the metal plate workpiece. At the same time, the threaded column 11 can be rotated forward according to the thickness of the metal plate workpiece. When the threaded column 11 rotates, it can drive the limiting block 12 to rotate and move closer to the metal plate workpiece. When the limiting block 12 moves to a certain distance from the top surface of the metal plate workpiece, the rotation of the threaded column 11 can be stopped. The bottom of the limiting block 12 does not contact the top of the metal plate workpiece.

[0022] See Figure 1 and Figure 2 As can be seen, when personnel push the metal plate workpiece, the four sets of rotating columns 14 can limit the metal plate workpiece. At the same time, when the side of the metal plate workpiece contacts the rotating column 14, it can drive the rotating column 14 to rotate through the connecting rod 13, so that the rotating column 14 can provide auxiliary guidance for the metal plate workpiece. The limiting block 12 can prevent the workpiece from tilting during the movement. In this way, the metal plate workpiece is less likely to have a large positional displacement when personnel push it to move, thereby improving the accuracy of the punching position of the metal plate workpiece.

[0023] See Figure 1 and Figure 3It can be seen that a fixed seat 15 is connected to the outside of the main body 1 of the stamping machine, a connecting shaft 16 is connected inside the fixed seat 15, a support plate 17 is rotatably connected to the outside of the connecting shaft 16, a support frame 18 is connected to the surface of the support plate 17, a rotating shaft 19 is connected to the bottom of the support plate 17, a support rod 20 is rotatably connected to the outside of the rotating shaft 19, an L-shaped connecting block 21 is welded to the end of the support rod 20, a fixed block 22 is welded to the outside of the main body 1 of the stamping machine near the L-shaped connecting block 21, and a pin 23 is inserted between the fixed block 22 and the L-shaped connecting block 21. The pin 23 is T-shaped.

[0024] In practical implementation, during the use of the metal stamping machine, the tail ends of some long metal sheet workpieces need to be supported by personnel to prevent them from collapsing. Frequent lifting by personnel increases labor costs. The support plate 17 can be pulled away from the main body 1 of the stamping machine. When the support plate 17 moves, it can rotate via the connecting shaft 16. The rotation of the support plate 17 drives the support frame 18 and the rotating shaft 19 to rotate and move. When the support plate 17 rotates to its maximum angle, it is perpendicular to the main body 1 of the stamping machine. Simultaneously, the top of the support frame 18... When the top of the stamping base 2 is at the same level as the top of the stamping base 2, the support rod 20 can be pushed towards the main body 1 of the stamping machine. When the support rod 20 moves, it can be rotated through the rotating shaft 19. When the support rod 20 rotates, it can drive the L-shaped connecting block 21 to move. When the end of the L-shaped connecting block 21 moves to the position below the fixed block 22, the pin 23 can be inserted into the fixed block 22. The end of the pin 23 can pass through the fixed block 22 and the L-shaped connecting block 21. At this time, the pin 23 can limit the L-shaped connecting block 21, thereby fixing the support plate 17 and the support frame 18.

[0025] See Figure 1 and Figure 3 It can be seen that the support frame 18 can help support the tail end of the metal plate workpiece, so that the personnel do not need to lift the tail end of the metal plate workpiece for a long time, thereby reducing the labor of the personnel.

[0026] In summary, when using this metal stamping machine to prevent workpiece displacement, the metal plate can be placed in the center of the stamping base 2 first, and then the two sets of bidirectional lead screws 8 can be rotated forward. When the bidirectional lead screws 8 rotate, they can drive the two sets of moving plates 9 to slide closer to each other. The four sets of rotating columns 14 can limit the metal plate workpiece. At the same time, when the side of the metal plate workpiece contacts the rotating column 14, it can drive the rotating column 14 to rotate through the connecting rod 13, so that the rotating column 14 can provide auxiliary guidance for the metal plate workpiece. The limiting block 12 can prevent the workpiece from tilting during movement. In this way, the metal plate workpiece is less likely to have a large positional displacement when the operator pushes it to move, thereby improving the accuracy of the punching position of the metal plate workpiece. The support frame 18 can assist in supporting the tail end of the metal plate workpiece, so that the operator does not need to lift the tail end of the metal plate workpiece for a long time, thereby reducing the labor of the operator. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
