Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, and in particular to a hardware stamping and bending die. Background Technology

[0002] In the hardware processing industry, stamping and bending are the core processes for manufacturing hardware structural parts. Hardware stamping and bending dies, as key equipment, are widely used in the production of parts in the fields of home appliances, automobiles, and machinery.

[0003] However, existing metal stamping and bending dies still have the following shortcomings: 1. The placement structure of existing metal stamping and bending dies is a fixed design, which cannot flexibly adjust the placement spacing according to the size of the metal parts. Different dies need to be replaced for different specifications of metal parts, which not only increases equipment costs but also prolongs production preparation time; 2. Existing metal stamping and bending dies can only achieve lifting and lowering movements in one direction, making it difficult to adjust the horizontal position to align with the bending point of the metal parts. Moreover, during the pressing process, uneven force can easily cause the pressure plate to tilt, resulting in deviations in the bending angle of the metal parts and affecting the product qualification rate. Therefore, we have introduced a new metal stamping and bending die. Utility Model Content

[0004] The main purpose of this utility model is to provide a metal stamping and bending die that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A metal stamping and bending die includes a first L-shaped support plate and a second L-shaped support plate. A plurality of first and second L-shaped support plates are provided.

A control device is inserted into the right side of the upper part of the top plate. A pressing device is inserted into the upper part of the control device. A first connecting plate is fixedly connected to the upper right side of the plurality of first L-shaped support plates. A second connecting plate is fixedly connected to the upper left side of the plurality of second L-shaped support plates.

[0007] Preferably, the control device includes a servo motor and a guide plate. The output end of the servo motor is fixedly mounted with a driving bevel gear, and the outer surface of the driving bevel gear is meshed with a driven bevel gear. The left end of the driven bevel gear is fixedly connected with a threaded screw, and the outer surface of the threaded screw is threaded with a transmission assembly. Two guide plates are provided, and each of the two guide plates has a through guide groove at its front end. The lower end of the servo motor is fixedly connected to the upper end of the top plate, and the output end of the servo motor passes through the upper end of the top plate and extends to the lower end of the top plate. The upper ends of both guide plates are fixedly connected to the lower end of the top plate.

[0008] By adopting the above technical solution: the servo motor drives the threaded screw to rotate through the active bevel gear and the driven bevel gear, which can drive the transmission component to move to adjust the position of the pressing device and adapt to the bending requirements of different hardware parts.

[0009] Preferably, the pressing device includes a hydraulic cylinder, a pressure plate is fixedly installed at the output end of the hydraulic cylinder, a balance guide rod is fixedly connected at each of the four corners of the upper end of the pressure plate, and an anti-detachment block is fixedly connected to the upper end of each of the four balance guide rods.

[0010] By adopting the above technical solution, the hydraulic cylinder provides stable pressure to the pressure plate, ensuring that the bending force of the hardware is sufficient and uniform.

[0011] Preferably, the bending assembly includes a fixed base, a first placement seat is fixedly connected to the upper left part of the fixed base, an adjustment groove is opened in the middle of the front end of the fixed base, a plurality of first limiting screw holes are opened in the upper part of the front end of the fixed base, an adjustment component is movably sleeved in the adjustment groove, and the lower end of the fixed base is fixedly connected to the upper end of the base plate.

[0012] Preferably, the adjustment assembly includes a U-shaped adjustment plate and a limiting screw. A second placement seat is fixedly connected to the upper end of the U-shaped adjustment plate, and a second limiting screw hole with internal and external penetration is opened at the front end of the U-shaped adjustment plate.

[0013] Preferably, the lower part of the U-shaped adjusting plate is movably sleeved in the adjusting groove, and the outer surface of the limiting screw is threadedly connected to the inner wall of the second limiting screw hole and extends into the corresponding first limiting screw hole.

[0014] By adopting the above technical solution: the U-shaped adjustment plate and the adjustment groove cooperate to achieve flexible movement, and the limit screw is connected and fixed to the U-shaped adjustment plate through the screw hole. The operation is simple and the fixation is firm, avoiding the displacement of the adjustment component when the hardware is bent.

[0015] Preferably, the transmission assembly includes a transmission plate, with T-shaped guide blocks fixedly connected to both the front and rear ends of the transmission plate. The front upper part of the transmission plate has four through guide holes, and the inner wall of the transmission plate is threadedly connected to the outer surface of the threaded lead screw.

[0016] By adopting the above technical solution: the transmission plate is threadedly connected to the threaded screw, and can move horizontally as the threaded screw rotates, providing an installation carrier for the pressing device; the T-shaped guide block is adapted to the guide groove to ensure smooth movement of the transmission plate; and the guide hole provides movement space for the balance guide rod.

[0017] Preferably, the right end of the driven bevel gear is movably connected to the left end of the second connecting plate via a rotating shaft, and the left end of the threaded screw is movably connected to the right end of the first connecting plate via a rotating shaft.

[0018] By adopting the above technical solution, the first connecting plate and the second connecting plate provide support for the threaded screw and the driven bevel gear through the rotating shaft, reducing the shaking when the two rotate, ensuring transmission stability, and improving the overall structural rigidity of the device.

[0019] Preferably, portions of the two T-shaped guide blocks that are close to each other are respectively movably fitted into corresponding guide grooves.

[0020] By adopting the above technical solution: the cooperation between the T-shaped guide block and the guide groove restricts the transmission plate to move only along the direction of the guide groove, avoids the transmission plate from rotating or deviating, and ensures that the horizontal position of the pressing device is accurately adjusted.

[0021] Preferably, the lower end of the hydraulic cylinder is fixedly connected to the upper end of the transmission plate, and the output end of the hydraulic cylinder passes through the upper end of the transmission plate and extends to the lower end of the transmission plate.

[0022] The four balance guide rods are respectively movably sleeved in the corresponding guide holes.

[0023] By adopting the above technical solution: the balance guide rod cooperates with the guide hole to limit the movement direction of the pressure plate, ensuring that the pressure plate always presses down smoothly and reducing the bending error of the hardware parts.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In this utility model, the adaptability of the mold is improved by the adjustable bending component. When using it, first slide the U-shaped adjustment plate in the adjustment groove of the fixed seat according to the size of the hardware parts, adjust the distance between the second placement seat and the first placement seat, and then use the limiting screw to pass through the second limiting screw hole and screw into the corresponding first limiting screw hole to fix it. Different specifications of hardware parts can be adapted without changing the mold, reducing equipment costs and shortening production preparation time.

[0026] 2. In this utility model, the bending accuracy is improved by the cooperation of the control device and the pressing device. When in use, the servo motor is started, and the threaded screw is driven to rotate through the active bevel gear and the driven bevel gear. The transmission component slides along the guide groove through the T-shaped guide block to adjust the horizontal position of the hydraulic cylinder. After the hydraulic cylinder is started, the balance guide rod slides along the guide hole to ensure that the pressure plate is pressed down smoothly. The anti-detachment block prevents the balance guide rod from detaching, effectively reducing the bending angle deviation and improving the pass rate of hardware processing.
