[0027] To describe in detail the structure of the pipe clamp bending device of this utility model, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0028] Figure 1A schematic structure of a pipe clamp bending device according to an embodiment of the present invention is shown.
[0029] like Figure 1 As shown, the pipe clamp bending device of this utility model includes a base 1, a fixing part disposed on the base 1, and a rotating part disposed at a distance from the fixing part. One end of the workpiece to be bent (the original material forming the pipe clamp) is fixed in the fixing part, and the other end is rotated under the drive of the rotating part, thereby realizing the bending of the workpiece at any angle. The rotating part includes a rotating shaft fixed on the base 1, a handle 4 that limits the rotation on the rotating shaft, and a limiting part disposed on the handle 4. The fixing part includes a limiting slot 10 corresponding to the position of the rotating part. One end of the workpiece to be bent passes through the gap between the limiting part and the rotating shaft and is fixed in the limiting slot 10. Then, the handle 4 is rotated, and the other end of the workpiece to be bent is driven to rotate through the limiting part and the rotating part on the handle 4. By adjusting the position of the workpiece, the above operation is repeatedly performed to form a pipe clamp structure with a preset bending angle.
[0030] Specifically, the fixing part includes a positioning plate 9 provided on the base 1, a limiting groove 10 provided on the positioning plate 9, and a locking bolt 11 adapted to the limiting groove 10. A bolt hole can be provided on the limiting groove 10, and the locking bolt 11 is inserted into the bolt hole to lock the position of one end of the workpiece to be bent. The locking bolt 11 can be used to clamp or release one end of the workpiece.
[0031] Furthermore, the rotating shaft fixed to the base 1 includes a fixed shaft 5 vertically fixed to the base 1 and a limiting nut 3 sleeved on the fixed shaft 5. The end of the handle 4 can be sleeved on the fixed shaft 5 and rotated, and is limited by the limiting nut 3. The fixed shaft 5 can be made using bolts available on the construction site, i.e., one end of the bolt can be welded to the base 1 to fix the end 2 of the fixed shaft, and the other end is a shaft structure around which the handle 4 can rotate.
[0032] In the pipe clamp bending device of this utility model, the limiting part is set on the handle 4 and can rotate with the handle 4. It includes a screw 6 that penetrates the handle 4, a rolling bearing 7 sleeved on the screw 6, and a locking nut 8. The rolling bearing 7 is fixed on the screw 6 by the locking nut 8. The rolling bearing 7 is set here so that when bending the workpiece, the workpiece and the limiting part can roll contact, avoiding rigid contact friction between the workpiece and the screw 6.
[0033] It should be noted that, due to the large distance between the limiting groove 10 and the rolling bearing 7, the bending angle of the workpiece will be large when one end of the workpiece is fixedly bent through the limiting groove 10. Therefore, a slotted structure can be set at the upper end of the fixed shaft 5. One end of the workpiece to be bent can be pre-inserted into the slot, and then the other end of the workpiece to be bent can be rotated by the handle 4 to pre-bend one end of the workpiece to be bent. At this time, the bending requirements of small size or small angle can be met. Then, on this basis, the limiting groove 10 can be used to achieve further bending operations.
[0034] It is known that the distance between the rolling bearing 7 and the fixed shaft 5 is not less than the cross-sectional dimension of the workpiece to be bent, ensuring that the workpiece can pass smoothly between the fixed shaft 5 and the limiting part. One or more rolling bearings 7 can be set, and the specific setting can be flexibly made according to the size of the workpiece.
[0035] To improve the flexibility of the device and make it adaptable to bending operations of workpieces with different angles and sizes, several regularly distributed adjustment holes can be set on the handle 4. The screw 6 can be limited within any adjustment hole, thereby adjusting the distance between the screw 6 and the fixed shaft 5 through the adjustment holes. It can be applied to the production of pipe clamps with different sizes and bending curvature requirements.
[0036] In one specific embodiment of this utility model, the distance between the positioning plate 9 and the rotating shaft is 20mm-40mm, preferably 30mm, which can meet the manufacturing requirements of most pipe clamps.
[0037] In addition, in order to quantify the bending angle of the workpiece, so that the operator can grasp the bending angle and ensure the consistency between the pipe clamps, an arc-shaped angle scale can be set on the base 1. According to the angle scale, the user can easily understand the starting position of the handle 4 and the stopping position of the bending, so as to ensure the accuracy and consistency of the bending angle.
[0038] As a specific example Figures 2 to 5 The structural changes of flat steel as the workpiece to be bent are shown in different bending processes.
[0039] like Figure 2 As shown, first, the pipe clamp needs to be bent to the required dimensions, and then flat steel is cut according to these dimensions as the workpiece to be bent. Then, one end of the flat steel is passed through the slot at the end of the fixed shaft 5, and the handle 4 is rotated to bend one end of the flat steel at a 90-degree angle through the cooperation of the rolling bearing 7. Figure 3 As shown.
[0040] Similarly, take one end of the flat steel after bending it, insert the other end into the slot at the end of the fixed shaft 5, and turn the handle 90 degrees to bend the other end of the flat steel at a 90-degree angle as well. Figure 4 As shown.
[0041] Then, loosen the locking bolt 11, and insert the flat steel with both ends bent through the fixed shaft 5 and the screw 66 into the limiting slot 10 and the locking bolt 11. Then, rotate the handle 4 180 degrees to form the shape shown. Figure 5 The U-shaped pipe clamp structure shown can be used in this process to cut a small section of the pipe that needs to be clamped and put it on the outside of the fixed shaft 5 to protect the fixed shaft 5.
[0042] It is understood that the pipe clamp bending tool of this utility model can be used in the manufacture of pipe clamps with various structures such as U-shaped pipe clamps, C-shaped pipe clamps and hook-pin pipe clamps.
[0043] According to the above-mentioned pipe clamp bending device of this utility model, the workpiece can be pre-bent at a small angle or small size by the slot of the fixed shaft and the handle. Then, the workpiece to be bent is fixed in the limiting slot after passing through the gap between the limiting part and the rotating shaft. By rotating the handle, the other end of the workpiece to be bent is rotated to complete the bending of a large size or large angle. It is not only simple in structure and easy to operate, but also reusable and can meet the needs of pipe clamp manufacturing of various types and angles.
[0044] The pipe clamp bending device according to the present invention has been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the pipe clamp bending device proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
