Design of hot plate mechanism for PE pipe automatic welding machine
Abstract:PE pipe automatic welding machine in the PE pipe welding use in the field has an irreplaceable role, therefore, for its structure design and optimization is also an important important research。 Hot plate mechanism in the whole device plays the role of heating pipe, which for PE pipe automatic welding machine hot plate mechanism is the most important mechanism of which the crank connecting rod mechanism, hydraulic cylinder push crank connecting rod mechanism, and ultimately drive the whole hot plate Carry up the movement。 The focus of this paper is to simulate the crank linkage with the matlab simulation program to obtain the optimal parameters to optimize the lifting action of the hot plate mechanism of PE pipe automatic welding machine。 After matlab simulation of the parameters and data window, proven, are in line with the requirements given, but also in line with the actual production needs, this article also made a new improvement to the body for the demand PE pipe automatic welding machine Enterprises to provide a new design。
