Detailed ways

The utility model is described in detail below in conjunction with specific embodiments.

Specifically, the pipe bender is composed of 21 parts and components. Among them, the pipe mold 1 is vertically inserted into the transmission box 5, and is movably matched with the bearing 17 inside, and is plugged into the small rotating shaft 7 outside the transmission box. Connect, and drive the pointer 8 on it to rotate, and the transmission box 5 is connected with the workbench 20 screws. The small rotating shaft 7 and the first scale plate 4 are for dynamic cooperation, and the first scale plate 4 below is screwed and installed with the workbench 20 . Rotate 360 degrees through the pipe mold 1 and drive the pointer to rotate. From the view in direction B, it can be seen that the tray 14 is rigidly connected with the transmission box 5, and an adjustment block 15 is installed on it, which only moves horizontally in the y direction. There are locking screws 21 under it, and the adjustment block 15 is equipped with a support frame 18 and a fine-tuning handwheel 13 , Adjust the front end of the bracket to be threaded and the rear end to be sliding to make X-direction horizontal movement. By adjusting the fine-tuning hand wheel 13, the guide wheel 12 is moved to the pipe 11, preventing the pipe from moving in the X direction, and the pipe fitting only slides in the Y direction. The guide wheel 12 is connected with the supporting frame 18 in a moving fit. The adjustment pin 9 is only used for pipe bending rotation angle positioning to ensure the bending space angle. The mandrel seat 16 is adjusted by a vertical thread to clamp the mandrel, and is rigidly fixed with the workbench 20 .

Wherein, the steps of the method of use are described as follows. First, the pipe mold 1 of the required specification is packed into the transmission box 5 and connected with the small shaft by plug-in. Insert the pipe 11 into the pipe mold 1 and the sliding clamping block 2, adjust the sliding clamping block 2 to move horizontally in the x and y directions, and after the adjustment is in place, rotate the clamping handle 3 to clamp the pipe. Then quickly move the adjustment block 15 on the tray mechanism along the Y direction to make it reach the bending point of the pipe, and the locking screw 21 is locked. Adjust the fine-tuning handwheel 13 on the tray 14 again, so that the guide wheel 12 clamps the pipe. Finally, turn the 10 wrench easily, and bend the degree according to the size of the pipe on the drawing, and the degree indicated by the pointer on the first dial 4 is enough. Unclamp the clamping handle 3, withdraw from the fine-tuning handwheel 13, and just can take out the formed pipe. The space angle of the bent pipe can be calculated by the second dial 6 through the diameter of the pipe die and the angle of the drawing to calculate H=tgα×D/2. Adjust scale H with adjustment pin 9 and get final product. Need to make a sample first. When bending thin-walled pipe fittings, mandrels or sand can be used for bending.

The pipe mold 1 and the guide wheel 12 of the equipment match the pipe specification, which is convenient for assembly and disassembly and reliable positioning. The lower part of the workbench 20 is equipped with rollers, which is easy to move and is suitable for on-site pipe configuration.

After use, it can bend steel pipes, copper pipes, stainless steel pipes with diameters below 3020-30 and thin-walled elliptical and square pipes. The bending curvature can reach twice the pipe diameter, and the ellipticity is controlled between 3% and 4%, which is very labor-saving. Easy to operate, small in size, high in efficiency and easy to move.
