Embodiment

[0025] Such as Figure 1-2 As shown, the present invention is used for a PVC pipe flaring device, including a fixed table 1, a PVC pipe heating and flaring device 2 arranged on the fixed table 1, and a PVC pipe flaring mold device 3 arranged at the front end of the fixed table 1 , because the inner diameter of the heating jacket 10 cannot be separated from the outer diameter of the PVC pipe 8 too far, and the flaring of the PVC pipe 8 cannot be taken out from the rear end, by designing the heating part of the PVC pipe mouth and the part of the flaring mold into a separate structure, it is convenient for the expansion of the PVC pipe Take it out after the mouth, which improves the flaring efficiency; the fixed table 1 is provided with a dovetail chute 4; the PVC pipe heating and flaring device 2 includes a dovetail moving block 5, a moving clamping frame 6, a PVC pipe heating device 7, and a dovetail moving block 5 The dovetail chute 4 set on the fixed table 1 slides inside, an...

Abstract

The invention discloses a device for expanding the opening of a PVC tube. The device comprises a fixing table, a PVC tube heating opening expanding device and a PVC tube opening expansion mold device, wherein the PVC tube opening expanding device is arranged on the fixing table; the PVC tube opening expansion mold device is arranged at the front end of the fixing table; a dovetail chute is formed in the fixing table; the PVC tube heating opening expanding device comprises a dovetail moving block, a moving clamping rack and a PVC tube heating device; the dovetail moving block is arranged inside the dovetail chute in the fixing table to slide therein; the moving clamping rack is movably arranged on the dovetail moving block to clamp and fix the PVC tube; the PVC tube heating device is arranged at the front end part of the dovetail moving block; the PVC tube heating device comprises a heating guide block, a heating sleeve and an opening expansion external mold; a heating guide hole is formed in the heating guide block; the heating sleeve is movably arranged at the front end part of the heating guide hole; the opening expansion external mold is arranged at the outer end in front of the heating guide hole; and the internal heating diameter of the heating sleeve is 2-3mm greater than the external diameter of the heated tube. By adopting the device, the heating efficiency can be improved, and the electric energy can be saved.

Description

technical field [0001] The invention relates to the field of PVC pipe processing, in particular to a flaring device for PVC pipes. Background technique [0002] Pipes are facilities used for water supply and drainage in people's daily life. The length of pipes is limited during production. In order to meet the requirements of long-distance water transportation, it is necessary to connect multiple sections of pipes. For PVC or HDPE pipes, socket joints are generally used. Therefore, it is necessary to have different radii at both ends of the pipe. Since this type of pipe is tubular with the same overall radius after preliminary molding, it is necessary to further process one end of the pipe by flaring. Existing PVC pipe flaring and reprocessing are all manually operated step by step. Since the process of heating and softening the pipe is all done manually, and the heating time is also manually controlled by the workers, it is difficult to control the heating time and the qual...
