DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-Figure 4 As shown, a pipe bending device for PE pipe processing, a driven gear 8 and a driving gear 12 are meshed, the driven gear 8 and the transmission chain 7 are meshed, the first screw rod 3 and the driven gear 8 are threadedly connected, the first screw rod 3 and the anti-dropout cap 11 are welded, the second screw rod 16 and the third fixing frame 18 are threadedly connected, the diameter of the anti-dropout cap 11 is larger than the diameter of the first screw rod 3, and the anti-dropout cap 11 is used to prevent the first screw 3 from falling out of the driven gear 8.
[0023] like Figure 1-Figure 4As shown, the spacing between the four groups of second limit frames 20 is the same, and the center of the circle of the first limit frame 9 is coaxial with the center point of the spacing between the second limit frames 20. The rotating handle 17 is welded to the second screw 16 to facilitate the user to rotate the second screw 16. The bending head 19 can be made of fine steel or stainless steel. The anti-slip silicone pad 10 is used to prevent the PE pipe from shaking when bending, affecting the bending effect.
[0024] It should be noted that the utility model is a pipe bending device for PE pipe processing. When in use, the user adjusts the height of the heating rod 15 according to the size of the PE pipe, so that the heating rod 15 can be close to the surface of the PE pipe, and the second screw 16 is driven to rotate by turning the rotating handle 17, so that the connecting frame 4 changes its height. The balance rod 14 is used to maintain the balance of the connecting frame 4, and then the PE pipe is placed between the upper and lower groups of first limit frames 9. At most three groups of PE pipes can be placed, so that the front end of the PE pipe is inserted into the gap between the second limit frames 20 and is located on the left side of the pipe bending head 19. At the same time, the heating rod 15 heats and softens the outer wall of the PE pipe.
[0025] The motor 13 drives the driving gear 12 to rotate, the driving gear 12 drives a group of driven gears 8 to rotate, the driven gear 8 drives the transmission chain 7 to transmit the other two groups of driven gears 8, so that the three groups of driven gears 8 drive the first screw 3 to rotate, thereby driving the three groups of first limiting frames 9 to move up and down until the anti-slip silicone pad 10 on the outer wall of the first limiting frame 9 is close to the surface of the PE pipe. At this time, after the outer wall of the PE pipe is heated and softened, the cylinder 5 drives the bending head 19 to extend to the left, so that the three groups of PE pipe ports are bent at the same time, the cylinder 5 drives the bending head 19 to retract, and the motor 13 drives the first limiting frame 9 to rise, and the user takes down the PE pipe to complete the PE pipe bending operation.
