Automotive decorative strip hot melt riveting point welding machine
Automotive decorative strip hot melt riveting spot welding machine by electric heating method to transfer heat from the heating plate to the hot riveting head, the hot riveting head heats the riveting column, makes it melt, and then blows up the cooling curing, forming the rivethead, fixing the product. The whole machine is in the form of a frame, which is composed of two large plates of the upper mold (hot rivet head) and the lower mold, and the action mode is pneumatic control. Mainly suitable for household appliances, lamps, automotive dissolvers and other plastic parts welding. According to the size of different plastic parts, the heating power and mold size can be set to achieve a variety of plastic workpiece welding, simple operation and easy to use. The upper mold is composed of a heating plate, a hot rivet head and a blow pipe, which is heated by an electric heat pipe and cooled and cured by the blow pipe.
Performance of automotive decorative strip welding machine:
- With good work efficiency, each action mechanism can be moved at the same time or separately;
- The welding of this machine has the characteristics of high strength and good performance;
- Automatic control technology is adopted to make welding operation easy and simple;
- All moving parts are made of linear bearings, cylinders and guide shafts to make the movement smooth and precise.
- no pollution, no waste, low noise, more environmentally friendly work.
Equipment technology and working principle: hot melt welding of thermoplastic materials, is the use of hot plate plastic welding machine using the principle of electric melting, accurate control of temperature changes, and equipped with perfect mechanical devices to achieve perfect welding. It has excellent results for workpieces with large workpiece areas, complex and high welding requirements.
Frame: steel, casting and bolt and welded connection structure.
Mold: the use of positioning structure, installation and commissioning is convenient, fast, accurate positioning, composed of several hot plates composed of hot molds. Both types of plastic parts can be used.
Motion control: PLC automatic control; Servo system.
Introduction to welding procedures:
The whole machine action system controls the welding body to the desired position— the cold mold automatic feeding —- the internal action of the welding body begins— completes the first plastic parts welding —– and the welding body is brought into the next welding position by the whole machine action system—- the next welding cycle.
Operation process: First, the large plastic parts are manually put into the lower cooling mold on the machine table, and fixed well, and the two kinds of upper plastic parts (small hooks) are neatly arranged into the two feeding slots on the machine table, which can be discharged in batches; Then start the device and the device will automatically complete the welding of all the dots. Finally, the welded workpiece is removed from the machine table by hand and then the next cycle is carried out.
