The hot-melt welding machine
14 Sep 2018
The hot-melt welding machine adopts a plate-type structure and uses an electric heating method. The whole machine is in the form of a frame. It consists of three plates: upper template, lower template and hot template. It is equipped with hot mold, upper and lower plastic cold molds, and the action mode is pneumatic control. It is mainly used for welding of plastic parts such as household appliances, car lights and car dissolvers. According to different plastic parts, the heating power and mold size can be set to realize welding of various plastic workpieces, which is easy to operate and convenient to use. product description The device adopts a plate-type structure, and the heat of the heating plate is transferred to the welding surface of the upper and lower plastic heating members by an electric heating method. The surface is melted, and then the heating plate is quickly withdrawn. After heating the upper and lower heating members, the molten surface is fused, solidified and integra...

Manual hot melt butt welder The manual hot-melt butt welder consists of a frame, a milling cutter, a heating plate, and a hydraulic control box, as shown in the following figure. The performance and characteristics of this series of welders are: 1 Suitable for hot melt butt joint of PE, PP and other plastic pipes; 2 The whole machine is composed of hydraulic station, electrical box, frame, heating device and milling device; 3 split structure, all parts are light and easy to move, the clamp is separated from the operating platform, easy to operate under the ditch; 4 The docking pressure is provided by the hydraulic power source, and the cutting pressure is provided by the three-phase power source, so that the whole machine is reliable in operation and stable in operation; 5 fixture adopts double ferrule superimposed structure, the pipe docking precision is high, and it is easy to adjust the wrong amount; 6Adopting the electromagnetic reversing valve to control the advance and retreat of...
Take out the milling cutter

(3) Take out the milling cutter, close the ends of the two tubes and check the alignment of the two ends. The displacement of the two ends of the pipe should not exceed 10% of the thickness of the pipe or the larger of 1mm. The pipe straightness and the tightness can be corrected to some extent. When the pipe is closed, there is no obvious gap between the two ends of the pipe. The maximum width cannot exceed: 0.3mm (DN< 225mm), 0.5mm (225mm<DN<400mm) or 1.0mm (DN>400mm). If the above requirements are not met, they should be milled again until the above requirements are met. (4) Measure the drag force (the frictional resistance of the moving fixture), this pressure should be superimposed on the process parameter pressure to get the actual use pressure. Also check if the heater plate temperature has reached the set value. (5) After the temperature of the heating plate reaches the set value, put it into the frame and apply the specified pressure until the minimum curl on both ...
welding Welding shall be carried out in accordance
13 Aug 2018
welding Welding shall be carried out in accordance with the parameters of the welding process card. When necessary, it should be appropriately adjusted according to changes in weather, ambient temperature, etc. The main steps are as follows. (1) Clean the dirt on both ends with a clean cloth. Place the tubing in the rack slips so that the length of the ends is equivalent (should be as short as possible, usually 25 to 30 mm, if the milling and heating requirements are met). If necessary, the outside of the pipe rack is lifted with the support so that the pipe axis is at the same height as the centerline of the frame and then fastened with the slips. See below. (2) Insert the milling cutter, first turn on the power switch of the milling cutter, then slowly close the welded ends of the two pipes, and apply appropriate pressure until there are continuous chips at both ends, remove the pressure, wait a moment, then exit the activity. Rack, turn off the power to the milling cutter. The chip ...
Use of hot melt butt welder
06 Aug 2018
Use of hot melt butt welder 1, welding preparation The preparation for welding is mainly to check whether the condition of the welding machine meets the working requirements. For example, check whether the fasteners in various parts of the machine are loose or loose; check whether the electrical connection of the whole machine is correct and reliable; check whether the hydraulic oil in the hydraulic tank is sufficient; confirm that the power supply matches the requirements of the machine; whether the heating plate meets the requirements (Whether the coating is damaged); trial operation of milling cutters and oil pump switches, etc. Then insert the slips with the same pipe specifications into the rack; set the temperature of the heating plate to the welding temperature (the welding temperature of the polyethylene pipe is 200~230 °C), and wipe the heating plate with soft paper or cloth alcohol before heating. Surface, but be careful not to scratch the PTFE release layer. https://www.chbu...
