Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and specifically to a bending machine for hardware parts. Background Technology

[0002] A bending machine is a machine capable of bending thin plates. Its main structure includes a support frame, a worktable, and a clamping plate. The worktable is placed on the support frame and consists of a base and a pressure plate. The base is connected to the clamping plate via a hinge. The base comprises a housing, a coil, and a cover plate. The coil is placed in a recess within the housing, and the top of the recess is covered by the cover plate. During operation, the coil is energized by a wire, generating an attractive force on the pressure plate, thus clamping the thin plate between the pressure plate and the base. Because electromagnetic clamping is used, the pressure plate can be made to meet various workpiece requirements, and workpieces with side walls can be processed. Operation is also very simple.

[0003] When bending hardware parts, the parts are usually placed in the bending die, and the electric hydraulic rod drives the bending head to press down and bend the parts. However, the sizes of hardware parts are often different, and different widths usually need to be bent. Since the bending die and the support plate are usually bolted together, it is inconvenient to adjust the size between the bending dies. Therefore, we propose a bending machine for hardware parts to facilitate the adjustment of the size between the bending dies, thus making it convenient to bend hardware parts to different widths. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a bending machine for hardware parts.

[0005] The technical solution adopted by this utility model to solve its technical problem is a bending machine for hardware parts, including a machine box and a support plate. An adjustment mechanism is installed on the wall of the support plate. The adjustment mechanism is composed of a slider A, a groove frame, a slide groove, a slider B, a threaded rod, and a semi-circular plate. A slide groove is opened on the wall of the support plate. Slider A and slider B are slidably connected to the inner wall of the slide groove. A threaded rod is threadedly connected to the wall of the support plate. Threaded holes are opened on the wall of slider A and slider B, and the direction of the threaded grooves in the threaded holes is opposite. The threaded rod is threadedly connected to the threaded groove. A groove frame is welded to the top of slider A and the top of slider B. A semi-circular plate for placing hardware parts is rotatably connected to the groove of the groove frame. A fixing frame is installed on the wall of the support plate by bolts.

[0006] By adopting the above technical solution, when bending different widths, an adjustment mechanism is installed on the wall of the bearing plate. The adjustment mechanism is composed of slider A, groove frame, slide groove, slider B, threaded rod and semi-circular plate. After the operator rotates the threaded rod according to the width of the hardware, threaded holes are opened on the wall of slider A and slider B, and the threaded grooves in the threaded holes are in opposite directions. The threaded rod is threadedly connected to the threaded groove. Thus, after rotating the threaded rod, slider A and slider B move towards each other in the slide groove. Since groove frames are welded to the top of slider A and slider B, the distance between the groove frames can be adjusted. After the operator places the hardware in the groove frame, the semi-circular plate is rotatably connected to the groove of the groove frame. When the bending head is pressed down, the hardware drives the semi-circular plate to rotate, thereby achieving the bending of the hardware and adjusting the bending width.

[0007] Specifically, it also includes a connecting mechanism, which is installed on the wall of the fixed frame.

[0008] By adopting the above technical solution, the connecting mechanism facilitates the connection of bending heads of different sizes.

[0009] Specifically, the connecting mechanism is composed of an electro-hydraulic rod, a concave plate, a bending head, a lead screw, a connecting plate, and a connecting hole. The top of the fixing frame is bolted with an electro-hydraulic rod, and the output end of the electro-hydraulic rod is fitted with a concave plate. A set of symmetrical lead screws are threaded onto the wall of the concave plate, and one end of each set of lead screws is connected to a connecting plate via a bearing. A connecting hole is provided on the wall of the connecting plate, and the wall of the connecting hole is bolted to the outer wall of the bending head.

[0010] By adopting the above technical solution, when connecting bending heads of different sizes, a connecting mechanism is installed on the wall of the fixed frame. The connecting mechanism consists of an electric hydraulic rod, a concave plate, a bending head, a lead screw, a connecting plate, and a connecting hole. After the operator rotates the lead screw on the concave plate, the lead screw pushes the connecting plate to move. After adjusting the distance between the connecting plates, the connecting hole is opened on the wall of the connecting plate, so the wall of the bending head is inserted between the connecting plates. The external bolt passes through the connecting hole and connects with the wall of the bending head, thereby fixing the bending head. This facilitates the connection of bending heads of different sizes. The electric hydraulic rod is controlled by the controller, causing the electric hydraulic rod to move the concave plate downward, so that the bending head bends the hardware below.

[0011] Specifically, a support plate is installed on the top of the chassis.

[0012] By adopting the above technical solution, the groove frame can be easily supported by the bearing plate.

[0013] Specifically, a controller for controlling the electro-hydraulic lever is installed at the door of the chassis.

[0014] By adopting the above technical solution, the electro-hydraulic rod can be easily controlled through the controller.

[0015] The beneficial effects of this utility model are:

[0016] (1) The bending machine for hardware parts described in this utility model can be used to bend different widths. Since the support plate is equipped with an adjustment mechanism, the adjustment mechanism is composed of slider A, groove frame, slide groove, slider B, threaded rod and semi-circular plate. After the operator rotates the threaded rod according to the width of the hardware part, threaded holes are opened on the block wall of slider A and the block wall of slider B, and the direction of the thread groove in the threaded hole is opposite. The threaded rod is threadedly connected to the thread groove. Thus, after rotating the threaded rod, slider A and slider B move towards each other in the slide groove. Since groove frames are welded to the top of slider A and the top of slider B, the distance between the groove frames can be adjusted. After the operator places the hardware part in the groove frame, the semi-circular plate is rotatably connected to the groove of the groove frame. Thus, when the bending head is pressed down, the hardware part drives the semi-circular plate to rotate, thereby realizing the bending of the hardware part and adjusting the bending width.

[0017] (2) The bending machine for hardware parts described in this utility model, when connecting bending heads of different sizes, has a connecting mechanism installed on the wall of the fixed frame. The connecting mechanism is composed of an electric hydraulic rod, a concave plate, a bending head, a lead screw, a connecting plate, and a connecting hole. After the operator rotates the lead screw on the concave plate, the lead screw pushes the connecting plate to move. After adjusting the distance between the connecting plates, the connecting hole is opened on the wall of the connecting plate, so that the wall of the bending head is inserted between the connecting plates. The external bolt passes through the connecting hole and connects with the wall of the bending head to fix the bending head, thereby facilitating the connection of bending heads of different sizes. The electric hydraulic rod is controlled by the controller, so that the electric hydraulic rod drives the concave plate to move down, thereby bending the hardware parts below.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses a bending machine for hardware parts, comprising a housing 1 and a bearing plate 2.

The adjusting mechanism 3 is composed of a slider A301, a groove frame 302, a slide groove 303, a slider B304, a threaded rod 305, and a semi-circular plate 306. A slide groove 303 is formed on the wall of the bearing plate 2. Sliding slider A301 and sliding slider B304 are slidably connected to the inner wall of the slide groove 303. 4. A threaded rod 305 is threadedly connected to the wall of the bearing plate 2. Threaded holes are provided on the wall of slider A301 and slider B304, and the threaded grooves in the threaded holes are in opposite directions. The threaded rod 305 is threadedly connected to the threaded groove. A grooved frame 302 is welded to the top of slider A301 and slider B304. A semi-circular plate 306 for placing hardware is rotatably connected to the groove of the grooved frame 302. A fixing frame 5 is installed on the wall of the bearing plate 2 by bolts.

[0026] In use, when bending to different widths, an adjustment mechanism 3 is installed on the wall of the bearing plate 2. The adjustment mechanism 3 is composed of a slider A301, a groove frame 302, a slide groove 303, a slider B304, a threaded rod 305, and a semi-circular plate 306. The operator rotates the threaded rod 305 according to the width of the hardware. Since both slider A301 and slider B304 have threaded holes on their walls, and the threaded grooves in the threaded holes are in opposite directions, the threaded rod 305 is threadedly connected to the threaded grooves, thus rotating the threaded rod. After the lever 305 is in place, sliders A301 and B304 move towards each other within the groove 303. Since both sliders A301 and B304 have grooved brackets 302 welded to their tops, the spacing between the grooved brackets 302 can be adjusted. When the hardware is placed in the grooved bracket 302, a semi-circular plate 306 is rotatably connected to the groove of the grooved bracket 302. When the bending head 603 is pressed down, the hardware drives the semi-circular plate 306 to rotate, thereby bending the hardware and adjusting the bending width.

[0027] like Figure 1 As shown, it also includes a connecting mechanism 6, which is installed on the wall of the fixed frame 5.

[0028] In use, the connecting mechanism 6 facilitates the connection of bending heads 603 of different sizes.

[0029] like Figure 1 and Figure 2 As shown, the connecting mechanism 6 is composed of an electric hydraulic rod 601, a concave plate 602, a bending head 603, a lead screw 604, a connecting plate 605, and a connecting hole 606. The electric hydraulic rod 601 is bolted to the top of the fixing frame 5. The output end of the electric hydraulic rod 601 is fitted with the concave plate 602.

The connecting mechanism 6 is composed of an electric hydraulic rod 601, a concave plate 602, a bending head 603, a lead screw 604, a connecting plate 605, and a connecting hole 606. After the operator rotates the lead screw 604 at the concave plate 602, the lead screw 604 pushes the connecting plate 605 to move. After adjusting the distance between the connecting plates 605, the wall of the connecting plate 605... A connecting hole 606 is provided, so that the plate wall of the bending head 603 is inserted into the connecting plate 605. The external bolt passes through the connecting hole 606 and connects with the plate wall of the bending head 603 to fix the bending head 603. This makes it convenient to connect bending heads 603 of different sizes. The controller 4 controls the electric hydraulic rod 601, so that the electric hydraulic rod 601 drives the concave plate 602 to move down, so that the bending head 603 bends the hardware below.

After the operator rotates the threaded rod 305 according to the width of the hardware, threaded holes are opened on the wall of slider A301 and the wall of slider B304, and the threaded grooves in the threaded holes are in opposite directions. The threaded rod 305 and the threaded rod are adjusted accordingly. The grooved thread connection allows the sliders A301 and B304 to move towards each other within the groove 303 after the threaded rod 305 is rotated.

After the operator rotates the lead screw 604 at the concave plate 602, the lead screw 604 pushes the connecting plate 605 to move. After adjusting the distance between the connecting plates 605, the connection... A connecting hole 606 is provided on the plate wall of plate 605, so that the plate wall of bending head 603 can be inserted into the connecting plate 605. The external bolt passes through the connecting hole 606 and connects with the plate wall of bending head 603 to fix bending head 603, thereby facilitating the connection of bending heads 603 of different sizes. The controller 4 controls the electric hydraulic rod 601, so that the electric hydraulic rod 601 drives the concave plate 602 to move down, thereby bending the hardware below the bending head 603.
