DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Example

[0023] like Figure 1-2 As shown, a plastic protective tube shaping device proposed by the utility model comprises a workbench 1, a base plate 2 is fixedly installed at the bottom of the workbench 1, a through hole 21 is opened at the top of the workbench 1, a cylinder 3 is fixedly installed on the top of the base plate 2 and is located directly below the through hole 21, a first mold 18, a second mold 19 and a third mold 20 with different diameters are fixedly installed on the telescopic rod of the cylinder 3, the three molds are cylindrical, and the same annular grooves are opened on the cylindrical curved surface, the cross-section of the annular groove is semicircular, and the diameter of the annular groove is the same as that of the processed plastic protective tube, and also comprises an L-shaped support seat 10 fixedly installed on the top of the workbench 1, a motor 11 is fixedly installed on the top of the L-shaped support seat 10, the output end of the motor 11 is rotatably connected to a rotating rod 12, and the outer wall of the rotating rod 12 is fixedly connected to a bending component that can be adjusted in position, after the plastic protective tube is clamped, the cylinder 3 is started, and the three molds fixedly installed on the telescopic rod are adjusted up and down, and the molds needed are adjusted to be flush with the top of the workbench 1, so as to realize the convenience of mold replacement, reduce the labor of workers, and improve work efficiency.

[0024] like Figure 1-2 As shown, a pushing mechanism is fixedly installed on one side of the workbench 1, and the pushing mechanism includes a fixed plate 4 fixedly installed on one side of the workbench 1, a motor 5 is fixedly installed on one side of the fixed plate 4, a slide groove 7 is opened on the top of the fixed plate 4, a screw rod 22 is rotatably installed inside the slide groove 7, the output end of the motor 5 is rotatably connected with the screw rod 22, a slider 6 is slidably installed on the inner wall of the slide groove 7, the screw rod 22 is threadedly connected with the slider 6, the plastic protective tube is placed on the inner side of the slider 6 on the fixed plate 4, the motor 5 is started, the screw rod 22 rotates at the same time, the slider 6 is displaced on the fixed plate 4, and the plastic protective tube is pushed onto the workbench 1, so that the plastic protective tube does not need to be pushed into the device for bending and shaping manually.

[0025] like Figure 1-4As shown, a clamping assembly located on one side of the pushing mechanism is fixedly installed on the top of the workbench 1, and the clamping assembly includes two electric telescopic rods 8 fixedly installed on the top of the workbench 1. The piston rod of the electric telescopic rod 8 is fixedly installed with a clamping block 9 that slides on the top of the workbench. Semicircular grooves are provided on the opposite sides of the two clamping blocks 9. Rubber pads are fixedly installed on the inner walls of the semicircular grooves provided on the clamping blocks 9. The setting of the rubber pads will not cause scratches on the surface of the plastic protective tube during the pushing and bending processes. The inner diameter of the semicircular groove is larger than the outer diameter of the processed plastic protective tube, so that the clamping will not be too tight, which will affect the pushing of the plastic protective tube by the pushing mechanism. The electric telescopic rod 8 is started to push the two clamping blocks 9 to move inward. When the two clamping blocks 9 are in contact, a circular channel is formed to clamp the plastic protective tube pushed by the pushing mechanism to prevent the plastic protective tube from shaking during bending and shaping.

[0026] like Figure 1-2 As shown, the bending assembly includes a mounting block 13 fixedly mounted on the rotating rod 12, and the mounting block 13 is located directly above the first mold 18. An electric telescopic rod 2 14 is fixedly connected to the curved surface of the mounting block 13.

The rotating wheel 17 contacts the mold to form a channel identical to the outer diameter of the plastic protective tube. After the plastic protective tube passes through the channel, the clamping assembly clamps the plastic protective tube, and the motor 2 11 is started, thereby driving the rotating rod 12 and the bending assembly fixedly mounted on the rotating rod 12 to rotate, and the rotating wheel 17 rotates along the outer diameter of the mold used to achieve bending and shaping of the plastic protective tube.

[0027] Working principle: The cylinder 3 is started to adjust the three molds fixed on the telescopic rod up and down, and the mold to be used is adjusted to be flush with the top of the workbench 1 to achieve the convenience of mold replacement, and then the heated plastic protective tube is placed on the inner side of the slider 6 on the fixed plate 4, the motor 5 is started, the screw rod 22 rotates at the same time, and the slider 6 moves on the fixed plate 4 to push the plastic protective tube onto the workbench 1, so that there is no need to manually push the plastic protective tube into the device for bending and shaping. The electric telescopic rod 8 is started to push the two clamping blocks 9 to move inward. When the two clamping blocks 9 are in contact A circular channel is formed to clamp the plastic protective tube pushed by the pushing mechanism to prevent the plastic protective tube from shaking during bending and shaping, and the plastic protective tube will not be clamped too tightly to affect the use of the pushing mechanism. After the plastic protective tube is clamped, the motor 11 is started to drive the rotating rod 12 to rotate, and then the electric telescopic rod 14 is adjusted to make the bending component wheel 17 always fit the outer wall of the mold.
