Laser welding and combined molding device and method of well seat of large-size plastic inspection well

Abstract

The invention relates to a laser welding and combined molding device and method of a well seat of a large-size plastic inspection well. The laser welding and combined molding device comprises a base and a stand column, wherein the stand column is fixed at the left side of the upper end of the base; the upper end of the stand column is movably connected with a cantilever beam through a hoisting mechanism with a servo motor; the cantilever beam is connected with a movable device; the bottom end of the movable device is connected with a laser output controller; a semiconductor laser device is arranged at the left side of the base; the semiconductor laser device is connected with the laser output controller through an optical fiber; the middle of the upper end of the base is movably connectedwith a rotary worktable; the left side of the top end of the rotary worktable is fixedly connected with a positioning block; the well seat of the large-size plastic inspection well is mounted at the upper end of the rotary worktable at the right side of the positioning block. According to the laser welding and combined molding device provided by the invention, a modularized combined type single-side panel and well seat bottom plate connection structure is adopted, and laser transmission welding of the semiconductor laser device is adopted, so that the device is convenient and flexible to operate and the welding efficiency is high; the designing and manufacturing cost of an injection mold and the difficulty of an injection molding technology are reduced; miniaturization of the injection mold and injection molding equipment and flexible production of the well seat of the large-size plastic inspection well are realized.

Description

technical field [0001] The invention relates to the field of forming and processing of large plastic inspection wells, in particular to a laser welding combined forming device and method for well bases of large plastic inspection wells. Background technique [0002] In the construction of municipal water supply and drainage pipe network systems, the market demand for large plastic inspection wells with a diameter of 700mm to 1000mm is increasing. The commonly used material for large plastic inspection wells is PP plastic. Large plastic inspection wells are generally composed of well covers, well chambers and The well base is composed of the well base, in which the well base undertakes branch pipes and well chambers in different directions, and bears the side pressure of the surrounding soil and the impact pressure of road vehicles during the installation of the pipe network. Therefore, the well base must have strong compressive, tensile and For this reason, manufacturers usu...
