Description

Technical Field

[0001] This utility model relates to the field of punch press technology, specifically a device for precisely adjusting the angle of a punch press mold. Background Technology

[0002] Punch presses are widely used machine tools in the sheet metal processing field. They primarily rely on various dies of different shapes and sizes to process sheet metal. On the same sheet metal, there are often holes of the same shape that need to be machined, distributed at different positions and angles. To complete the machining of these holes, the die placement angle must be adjusted one by one according to the requirements of the machining drawings. Traditional old-style punch presses require a significant amount of time to adjust these die angles, making it almost impossible to process complex parts on a single machine. Instead, according to the drawings, holes at different angles must be processed in different steps, each requiring a machine tool and a set of dies. Several machine tools must work together to complete the sheet metal processing according to the drawings.

[0003] The aforementioned processing flow requires a large number of machine tools and molds, which inevitably leads to high processing costs and time waste caused by the transfer between various processes;

[0004] Therefore, it is necessary to design a mechanism that allows the mold to automatically rotate at different angles. This mechanism can automatically rotate at different angles according to the requirements of the drawings, driven by a servo motor, to complete the processing of the same hole at different angles. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and provide a device for precise adjustment of die angle for punch presses.

[0006] The specific solution of this utility model is: a precise adjustment device for the mold angle of a punch press, including a base, a housing fixedly mounted on the base, a mold mounting seat mounted at the center of the housing, the mold mounting seat for mounting the mold, the lower end of the mold mounting seat being slidably connected to the base, the upper end of the mold mounting seat being slidably connected to the housing, a worm gear being fixedly mounted on the side wall of the mold mounting seat, a cavity corresponding to the worm gear being provided inside the housing, a worm being installed in the cavity, the worm matching the worm gear, both ends of the worm extending outward and rotatably connected to the housing, and one end of the worm being connected to a drive mechanism.

[0007] Furthermore, each end of the worm is equipped with a bearing seat, and a bearing is installed between the worm and the two bearing seats. The bearing seats are connected to the housing by bolts. The bearing seats are provided with bolt holes, and there is an adjustment gap between the bolt holes and the bolts. The housing is equipped with a set screw corresponding to each of the two bearing seats. The set screw is used to adjust the position of the bearing seat and thus adjust the gap between the worm and the worm wheel.

[0008] Furthermore, sealing rings are installed between the bearing housing and the housing and the worm gear, and sealing rings are installed between the base and the mold mounting base and between the housing and the mold mounting base. Each sealing ring forms a sealing area, and the worm wheel and the worm gear are located within the sealing area, which is filled with lubricating oil.

[0009] Furthermore, the upper end of the mold mounting base extends upward and is higher than the housing, and the side wall of the mold mounting base that is higher than the housing is provided with a mold mounting opening.

[0010] Furthermore, the outer ring of the worm gear is provided with transmission teeth, and the inner ring of the worm gear is provided with a keyway that mates with the mold mounting base. The inner ring and the mold mounting base are connected by a key.

[0019] See Figure 1-6This embodiment is a device for precisely adjusting the angle of a die for a punch press. It includes a base 1, a housing 2 fixedly mounted on the base 1, a die mounting seat 5 mounted at the center of the housing 2, the die mounting seat 5 for mounting a die 4, the lower end of the die mounting seat 5 being slidably connected to the base 1, and the upper end of the die mounting seat 5 being slidably connected to the housing 2. A worm gear 6 is fixedly mounted on the side wall of the die mounting seat 5. A cavity 21 is provided inside the housing 2 corresponding to the worm gear 6, and a worm 8 is installed in the cavity 21. The worm 8 matches the worm gear 6, and both ends of the worm 8 extend outward and are rotatably connected to the housing 2. One end of the worm 8 is connected to a servo motor, and the servo motor is signal-connected to the control system of the punch press. During operation, the control system sends a corresponding rotation angle signal to the servo motor according to the processing parameters. The servo motor precisely controls the number of rotations of the worm 8 according to the signal, thereby driving the worm gear 6, the die mounting seat 5, and the die 4 to rotate by a specified angle.

[0020] Furthermore, each end of the worm 8 is equipped with a bearing seat 3, and a bearing is installed between the worm 8 and the two bearing seats 3. The bearing seats 3 are connected to the housing 2 by bolts. The bearing seats 3 are provided with bolt holes, and there is an adjustment gap between the bolt holes and the bolts. The housing 2 is equipped with a fixing plate 10 corresponding to each of the two bearing seats 3. The fixing plate 10 is equipped with a set screw 9. One end of the set screw 9 abuts against the corresponding bearing seat 3. The set screw 9 is used to adjust the position of the bearing seat 3, thereby adjusting the gap between the worm 8 and the worm wheel 6, so that the worm wheel 6 and worm 8 mechanism can run smoothly and accurately, and ensure that the rotation angle accuracy of the mold 4 meets the requirements.

[0021] In this embodiment, the bolt hole size of the bearing housing 3 is larger than that of the locking bolt, so that the installation position of the bearing housing 3 has adjustable space. When adjusting the gap between the worm gear 6 and the worm 8, first loosen the locking bolt of the bearing housing 3, then adjust the set screw 9. By turning the set screw 9, the set screw 9 is moved axially, thereby pushing the bearing housing 3. After adjustment, tighten the locking bolt of the bearing housing 3 to fix the bearing housing 3.

[0022] Furthermore, a sealing ring 7 is installed between the bearing seat 3 and the housing 2 and the worm gear 8, and a sealing ring 7 is installed between the base 1 and the mold mounting seat 5 and between the housing 2 and the mold mounting seat 5. Each sealing ring 7 forms a sealing area, and the worm wheel 6 and the worm gear 8 are located within the sealing area. The sealing area is filled with lubricating oil to lubricate and cool down the moving friction parts.

[0023] Furthermore, the upper end of the mold mounting base 5 extends upward and is higher than the housing 2. The side wall of the mold mounting base 5 above the housing 2 is provided with a mold mounting opening 51, and the mold 4 is placed into the inner cavity of the mold mounting base 5 through the mold mounting opening 51.

[0024] Furthermore, the outer ring of the worm gear 6 is provided with transmission teeth, and the inner ring of the worm gear 6 is provided with a keyway that mates with the mold mounting base 5. The inner ring and the mold mounting base 5 are connected by a key.

[0025] The working principle of this utility model is as follows: Driven by a servo motor, the worm gear 6 and worm 8 are used to quickly rotate the mold mounting base 5 and the mold 4 to a specified angle, reducing vibration and offset during rotation, ensuring smooth rotation, extending the life of the equipment and the mold 4, greatly improving the utilization rate of the mold 4, saving the time for adjusting the angle of the mold 4, and improving work efficiency.
