Detailed Embodiment
[0021] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.
[0022] To better understand the above technical solution, the exemplary embodiments of the present utility model will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present utility model and to fully convey the scope of the present utility model to those skilled in the art.
[0023] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the specification drawings and specific implementation manners.
[0024] Next, refer to Figure 1 - Figure 2 , and a detailed description will be given of the implementation of the bending tooling proposed according to the embodiments of the present utility model.
[0025] The bending tooling according to the embodiments of the present utility model includes: a bending assembly 1 and a positioning assembly 2.
[0026] Specifically, the bending assembly 1 has an upper die 11 and a lower die 12, and the upper die 11 and the lower die 12 are oppositely arranged to jointly construct a bending space for bending the workpiece 7; the positioning assembly 2 has a first limiting member 21 and an eccentric adjusting member 22. The first limiting member 21 is movably arranged on the lower die 12 to abut against one end of the workpiece 7 in the length direction, and the eccentric adjusting member 22 is rotatably arranged to rotatably abut against the first limiting member 21 to adjust the distance between the first limiting member 21 and the bending space.
[0027] That is to say, the upper die 11 and the lower die 12 are oppositely arranged, so that a bending space is formed between the upper die 11 and the lower die 12. The workpiece 7 to be bent is placed in the bending space, and the end of the workpiece 7 abuts against the first limiting member 21, so that the distance from the abutted end of the workpiece 7 to the bending space is fixed. By rotating the eccentric adjusting member 22, the first limiting member 21 is moved, so that the first limiting member 21 approaches or moves away from the bending space, and further the distance from the abutted end of the workpiece 7 to the bending space is changed, and then bending is performed at different positions in the length direction of the workpiece 7 in cooperation with the upper die 11 and the lower die 12.
[0028] Thus, the upper die 11 and the lower die 12 for bending the workpiece 7 jointly construct a bending space for bending the workpiece 7. Through the cooperation of the first limiting member 21 and the eccentric adjusting member 22 of the positioning assembly 2, the first limiting member 21 is variably limited in the length direction of the workpiece 7, so that the workpiece 7 can be bent at different positions. The bending tooling has a simple structure, can bend workpieces 7 of different specifications, and has strong versatility.
[0029] For the movement of the first limiting member 21, the lower die 12 defines a sliding groove 121, and the first limiting member 21 is connected to the sliding groove 121. Understandably, through the cooperation of the first limiting member 21 and the sliding groove 121, the movement of the first limiting member 21 becomes smoother and more stable, facilitating the parallel approach or separation of the first limiting member 21 from the bending space. Among them, the number of sliding grooves 121 can be two, the openings of the sliding grooves 121 face vertically upward, the first limiting member 21 can be integrally long strip-shaped, convex blocks cooperating with the sliding grooves 121 are provided at both ends of the first limiting member 21, and scales can be engraved on the lower die 12 to facilitate observing the moving distance of the first limiting member 21.
[0030] For the abutting and maintaining between the first limiting member 21 and the eccentric adjusting member 22, an elastic member 3 is connected to the first limiting member 21, and the elastic member 3 can keep the first limiting member 21 abutted against the eccentric adjusting member 22. Understandably, through the action of the elastic member 3, the first limiting member 21 can be kept in contact with the eccentric adjusting member 22 at all times, so that when the eccentric adjusting member 22 rotates, the first limiting member 21 remains abutted against the outer contour of the eccentric adjusting member 22 to adjust the distance between the first limiting member 21 and the bending space. Among them, the elastic member 3 can be a spring, and the spring can be arranged at one end of the sliding groove 121 close to the bending space.
[0031] For the eccentric adjusting member 22, a plurality of adjusting surfaces 221 that can rotate synchronously with the eccentric adjusting member 22 are provided on the eccentric adjusting member 22, and each adjusting surface 221 is adapted to abut against the first limiting member 21 to adjust the distance between the first limiting member 21 and the bending space. Understandably, through the arrangement of the plurality of adjusting surfaces 221, it is convenient to fit and abut against the first limiting member 21, so that the moving position of the first limiting member 21 is more accurate, and further the bending accuracy of the workpiece 7 is guaranteed. Among them, digital numbers corresponding to the respective adjusting surfaces 221 can be engraved on the eccentric adjusting member 22 to facilitate the operator to quickly adjust the first limiting member 21 to a preset limiting length to match the corresponding workpiece 7; in addition, positioning holes corresponding to the respective adjusting surfaces 221 can also be provided on the lower surface of the eccentric adjusting member 22, and a ball head set screw is arranged on the lower die 12. When an adjusting surface 221 rotates to fit against the first limiting member 21, the ball head set screw just fits into the positioning hole, thereby improving the operator's operation feel and at the same time keeping the adjusting surface 221 from rotating after adjustment.
[0032] For the rotation of the eccentric adjusting member 22, the eccentric adjusting member 22 further includes a handle 23, and the handle 23 is adapted to drive the plurality of adjusting surfaces 221 to rotate synchronously. Understandably, through the arrangement of the handle 23, it is convenient for the operator to manually apply force to rotate the eccentric adjusting member 22. Among them, the handle 23 can be vertically arranged on the upper surface of the eccentric adjusting member 22, or horizontally arranged on the outer peripheral surface of the eccentric adjusting member 22.
[0033] For the limit in the width direction of the workpiece 7, there are also several second limit members 4. The several second limit members 4 are arranged on the lower die 12 to construct several limit channels that can limit the width direction of the workpiece 7. It can be understood that through the several limit channels constructed by the several second limit members 4, it is convenient to limit the width direction of the workpiece 7, thereby ensuring the bending accuracy of the workpiece 7. At the same time, multiple limit channels are convenient for limiting workpieces 7 of different specifications and facilitate the quick switching between workpieces 7 of different specifications. Among them, the second limit members 4 are arranged on both sides of the bending opening of the lower die 12. The second limit members 4 can be positioning pins, and the number of limit channels can be three.
[0034] For the installation of the upper die 11, there is also a connecting head 5. The upper die 11 is detachably connected to the connecting head 5. It can be understood that through the setting of the connecting head 5, it is convenient to install the upper die 11 on the output end of the hydraulic press through the connecting head 5. At the same time, the upper die 11 is detachably connected to the connecting head 5, which is convenient for replacing the upper die 11, thereby facilitating the different bending shape requirements of the workpiece 7. Among them, the connecting head 5 can be integrally in a T shape, and the upper die 11 and the connecting head 5 can be connected by screws.
[0035] For the installation of the lower die 12, there is also a mounting plate 6. The upper die 11 is detachably connected to the mounting plate 6. It can be understood that through the setting of the mounting plate 6, it is convenient to install the lower die 12 on the workbench of the hydraulic press through the mounting plate 6. At the same time, the upper die 11 is detachably connected to the mounting plate 6, which is convenient for replacing the lower die 12, thereby facilitating the different bending shape requirements of the workpiece 7. Among them, the mounting plate 6 and the lower die 12 can be fixed by screws.
