Description

Technical Field

[0001] The invention relates to a pipeline welding machine and a use method thereof. Background Art

[0002] The pipe welding machine is used for hot-melt butt welding of plastic pipes. It is an existing mature machine with similar structures. It includes a double-sided electric heating component and two horizontal slide rails. Each horizontal slide rail is provided with a pipe clamping component. The pipes to be welded are clamped by the pipe clamping components on both sides, and then the two pipe end faces are heated by the electric heating component at the same time. Then the electric heating component is withdrawn and the two pipes are pressed and welded along the slide rail. For the structure, please refer to Chinese patent CN96246010.9 or Chinese patent CN201310698773.7. The problem of the prior art is that the two pipes to be welded have the same specifications and sizes, but because they come from different manufacturers, or even from different batches of the same manufacturer, the formula and component content of the two pipes are slightly different. This slight difference will cause the melting points of the two pipes to be different. The traditional pipe welding machine is double-sided and the heating temperature cannot be controlled separately on both sides. This causes the pipes on both sides of the electric heating component to have different melting states at the same time. Welding at this time will result in poor welding effect. Summary of the invention

[0004] The second technical problem to be solved by the present invention is to provide a method for using the above-mentioned pipeline welding machine. The method has simple steps and is easy to use. The welding surfaces of the two pipelines to be welded can reach a consistent molten state under the same heating time, and the welding effect is good.

[0005] In order to solve the first technical problem mentioned above, the present invention provides a pipeline welding machine, including a vertically arranged electric heating component, a driving arm connected to the electric heating component and driving the electric heating component to move, horizontal slide rails running left and right are relatively provided on the left and right sides of the electric heating component, each horizontal slide rail is provided with a pipe clamping component, each pipe clamping assembly is driven by a motor to slide left and right on the corresponding slide rail, the electric heating component, the driving arm, and the motor are all connected to a power supply through a corresponding controller, the electric heating component includes two substrates arranged relatively to the left and right and with normal directions running left and right, a connecting piece is provided between the inner sides of the two substrates along the left and right directions, the driving arm is connected to the connecting piece, the left and right outer sides of the two substrates are embedded with electric heating plates, and the two electric heating plates are respectively connected to the power supply through a temperature control controller.

[0006] In order to solve the above second technical problem, the present invention provides a method for using the above pipeline welding machine, comprising the following steps:

[0007] (1) Using corresponding pipe clamping assemblies, fix two pipes to be welded on two slide rails respectively, and make one end of each pipe to be welded abut against the electric heating plate on the corresponding side of the electric heating assembly;

[0008] (2) According to the melting point characteristics of the two pipes to be welded, the heating temperatures of the two electric heating plates are set by the temperature controller respectively, so that the welding surfaces of the two pipes to be welded reach a consistent melting state under the same heating time;

[0009] (3) After reaching the molten state, the electric heating component is lifted by the driving arm, and then the two pipe clamping components are controlled to drive the corresponding pipes to move toward each other to complete the welding.

[0010] Advantages of the present invention: The electric heating assembly of the pipe welding machine provided by the present invention has independent temperature control on both sides, and can flexibly adjust the specific temperature of the electric heating plates on both sides according to the melting point of the pipe actually involved in welding.
