Description

Technical Field

[0001] The utility model relates to the technical field of bending machine molds, in particular to a disassembly-free multi-angle bending machine mold. Background Art

[0002] The non-disassembly multi-angle bending machine mold is a specific mold used in metal bending processing equipment. It has the characteristics of one-time installation and no disassembly, and the mold can be adjusted at multiple angles according to the actual bending processing requirements. Compared with traditional bending machine molds, this type of mold is convenient to directly adjust the angle position of the mold according to the actual processing requirements during production, and the corresponding bending groove can be replaced.

[0003] In actual use, the existing non-disassembly multi-angle bending machine mold is usually more convenient to adjust the lateral position. However, when the mold needs to be flanging adjusted, it is usually necessary to completely retract the lower limit adjustment structure on both sides of the mold, and then use manpower or additional auxiliary equipment to flanging the mold, which affects the actual mold adjustment efficiency. Therefore, those skilled in the art provide a non-disassembly multi-angle bending machine mold to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a disassembly-free multi-angle bending machine mold to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disassembly-free multi-angle bending machine mold, comprising a bending machine body, an assembly base plate, a bending mold, a mounting frame and a connecting shaft, the working end face of the bending machine body is fixedly connected to the assembly base plate, the bending mold is arranged on the upper end face of the assembly base plate, a pair of synchronous motors are fixedly connected to the upper ends of the mounting frames, the output ends of the pair of synchronous motors on both sides rotate through the upper ends of the mounting frames and are fixedly connected to threaded screws, the middle positions of the end faces of both sides of the bending mold are fixedly connected to connecting shafts, the ends of the pair of connecting shafts away from the bending mold are rotatably connected to threaded sleeves, the pair of threaded screws on both sides are threadedly matched with a pair of threaded sleeves, the outer end face of the threaded sleeve on one side is fixedly connected to a stepper motor, the output end of the stepper motor rotates through the threaded sleeve and is fixedly connected to the connecting shaft.

[0006] Furthermore, a control panel is fixedly connected to the center of the front end of the assembly base. The control panel is electrically connected to the multiple synchronous motors and the stepper motors. This structural design allows the operator to issue commands through the control panel to control the synchronous operation of the multiple synchronous motors and also to control the stepper motors to perform step-by-step output.

[0007] Furthermore, the stepper motor is set to work once with an angle of 90 degrees. This structural design allows the stepper motor to output once to control the bending die to rotate to the first edge when it is working. This design facilitates the rapid and accurate control of the bending die for flanging adjustment.

[0008] Furthermore, the bending die is provided with multiple bending grooves on its front and rear sides and upper and lower end surfaces, each of which has a different model. This design allows the bending die to be provided with a variety of different models of bending grooves, effectively expanding the processing range of the bending die itself and meeting various bending processing requirements.

[0009] Furthermore, the upper end surface of the assembly base plate is fixedly connected to a fixing plate at the front and rear sides and near the four corners. Hydraulic ejectors are fixedly connected to the middle positions of the outer end surfaces of multiple fixing plates. Each of the multiple hydraulic ejectors is electrically connected to the control panel. The fixing plate provided on the assembly base plate facilitates the installation and assembly of the hydraulic ejectors. The installation of the hydraulic ejectors and their electrical connection to the control panel facilitate the control of the hydraulic ejectors through the control panel to perform ejection operations.

[0010] Furthermore, the output ends of the plurality of hydraulic ejectors extend through the fixed plate and are fixedly connected to limit baffles, which are mutually limited and cooperate with the bending die. This structural design allows the bending die to be adjusted in the longitudinal direction through the synchronous ejection and retraction of the hydraulic ejectors. After the adjustment is completed, the bending die can be effectively stabilized during bending operations.

[0011] Furthermore, limit rails are provided at the middle positions of the end surfaces of both sides of the assembly base, and limit sliders are fixedly connected to the lower end surfaces of the frame bodies of the pair of mounting frames. The pair of limit sliders and the pair of limit rails slide in mutual limited sliding engagement. This design ensures that the bending mold's lifting and lowering adjustment structure can maintain stable positional movement while simultaneously adjusting its longitudinal position while adjusting its planar longitudinal position.

[0012] Compared with the existing technology, the utility model provides a disassembly-free multi-angle bending machine mold, which has the following beneficial effects:

[0013] The core design idea of ​​this non-disassembly multi-angle bending machine mold is that compared with traditional multi-angle bending molds that mostly use manual or additional auxiliary equipment to adjust the flange position of the bending mold, this equipment only requires the operator to control the electric lifting structure through the control panel to drive the mold to rise, and then control the stepper motor through the control panel to output the rated 90-degree rotation angle, drive the bending mold to rotate the rated 90-degree angle to complete the flanging adjustment. The overall structural design makes the equipment less efficient than traditional equipment that requires brute force or additional auxiliary equipment to adjust the flanging of the mold placed on the workbench. This equipment uses the electric lifting structure to lift the mold to a suspended state and then adjusts the rotation and flanging of the bending mold in the form of electric control, which greatly improves the efficiency of the mold flanging adjustment.

[0024] Furthermore, the stepper motor 14 is set to work once with an angle of 90 degrees. This structural design allows the stepper motor 14 to output once when working to control the bending die 12 to rotate to a single edge. This design facilitates the rapid and accurate control of the bending die 12 for flanging adjustment.

[0025] Furthermore, a plurality of bending grooves 13 are provided on the front and rear sides and the upper and lower end faces of the bending mold 12, and the models of the plurality of bending grooves 13 are different from each other; this design enables the bending mold 12 to be provided with a plurality of different models of bending grooves 133, so that the processing range of the bending mold 12 itself is effectively improved to meet various bending processing requirements. Example 2:

[0026] Based on the above embodiment 1, please refer to Figures 1 to 6 The upper end surface of the assembly base plate 10 is located on the front and rear sides and is fixedly connected to a fixed plate 8 near the four corners. The middle position of the outer end surface of multiple fixed plates 8 is fixedly connected to a hydraulic push rod 7, and multiple hydraulic push rods 7 are electrically connected to the control panel 11; the fixed plate 8 arranged on the assembly base plate 10 is convenient for installing and assembling the hydraulic push rod 7.

[0029] The working principle and use process of this utility model: When the device is actually used:

[0030] Operation 1: When the bending groove 13 that meets the processing requirements is located directly above the bending die 12 but not directly below the bending tool, the operator can issue a command through the control panel 11 to control the pair of hydraulic ejectors 7 located at the front and rear sides to work synchronously, and adjust the longitudinal position of the bending die 12 in the plane, so that the bending groove 13 that meets the processing requirements at the side of the bending die 12 directly above is adjusted to the position directly below the bending tool, and the adjustment is completed;

[0031] Operation 2: When the bending groove 13 that meets the processing requirements is located at the front and rear sides or the lower side of the bending mold 12, the operator issues a command through the control panel 11 to control the two pairs of synchronous motors 3 to work, provide power for the operation of the lifting structure of the bending mold 12, and adjust the bending mold 12 to rise. When the bending mold 12 is suspended in the air, the operator issues a command through the control panel 11 to control the synchronous motor 3 to stop working and lock it, and issues a command through the control panel 11 to control the stepping motor 14 to perform step output, and adjust the bending mold 12 to perform flanging adjustment until the side where the bending groove 13 that meets the processing requirements is located is directly above. At this time, the operator can issue a command through the control panel 11 to control the stepping motor 14 to stop working, and control the two pairs of synchronous motors 3 to reverse work, so that the bending mold 12 is lowered. When the lower side of the bending mold 12 contacts the upper end surface of the assembly base plate 10, the operator issues a command through the control panel 11 to control the synchronous motor 3 to stop working;

[0032] At this time, if the bending groove 13 that meets the processing requirements on the bending die 12 after flanging adjustment is not located directly below the bending tool, operation one is performed to adjust the bending groove 13 that meets the processing requirements to a position directly below the bending tool.
