Abstract

The invention discloses a lead rail actuator for fusion welding of plastic pipes. The lead rail actuator solves the technical problem that the socket fusion welding quality of the plastic pipes cannot be ensured in the prior art. The lead rail actuator comprises a base and more than one sliding blocks. The lead rail actuator is characterized in that: the base comprises a bracket and a baffle plate, the bracket is provided with a horizontal part and a vertical part, two sides of the top and / or the back of the horizontal part of the bracket are provided with raised rails, and two sides of the bottom of the sliding block are provided with grooves matched with the shapes of the rails; and the upper end and / or the lower end of the baffle plate are provided with circular indentations with unequal diameters, the sliding block is provided with a semi-cylindrical groove horizontally penetrating the sliding block, the circle centers of the circular indentations in the baffle plate and the semi-cylindrical groove in the sliding block are on the same axis, the circular indentations and the semi-cylindrical groove have diameter difference, and the diameter difference is equal to the thickness of the welded pipes. The lead rail actuator can improve the fusion welding quality level of the pipes, and is convenient to use, simple in machining and low in cost.

Description

technical field

[0001] The invention relates to a rail guide, in particular to a rail guide for welding plastic pipes, and belongs to the technical field of plastic processing. Background technique

[0002] The heating and welding of plastic pipes is one of the commonly used technologies in the field of construction and decoration to melt and connect PP-R, PE, and PB-type fusible plastic pipes. When the pipes are heated and welded, the pipes and fittings are usually first heated on the fuser, and then the heated pipes and fittings are removed simultaneously, and the pipes and fittings are quickly inserted together. In this process, it is necessary not only to ensure the coaxiality of the pipe and fittings, but also to ensure that the insertion depth of the fittings meets the requirements: if the insertion is too shallow, the strength will be affected, and if the insertion is too deep, the fusion blockage will be "blocked" or "unsmooth"; the insertion will not be straight Af...
