How to use hot melt butt welding machine

24 Feb 2022

The use of hot melt butt welding machine: 1. Preparation for welding Welding preparation is mainly to check whether the condition of the welding machine meets the working requirements. For example, check whether the fasteners of various parts of the machine are loose or loose; check whether the electrical circuit 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 input requirements of the machine; whether the heating plate meets the requirements (Whether the coating is damaged); Trial operation of milling cutter and oil pump switch, etc. Then put 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 machine is 200~230℃), before heating, use soft paper or cloth dipped in alcohol to wipe the heating plate surface, but be careful not to scratch the PTFE...

Maintenance and maintenance of electrical system of automatic hot-melt welding machine

14 Feb 2022

Because the fully automatic heat fusion welding machine needs to work in a very harsh environment, and often uses different types of power generation equipment and power sources, and may work with other electronic equipment at the same time, the equipment is not immune to electrical failures. In the process of using the automatic hot-melt welding machine, the maintenance of the equipment should be done well. Electrical equipment maintenance The connection plugs and sockets between the heating plate and the control box, and the connection parts between the frame signal frame and the frame must be kept dry. Be sure to check your computer for damage to the touch panel and for loose or damaged switches. Troubleshooting methods: The common faults of automatic hot-melt electrical systems include component aging faults, unexpected faults and human faults. The highest aging failure rate is the hot plate and the milling cutter; the highest accidental failure rate is the rack; the highest artifi...

How to choose a qualified automatic hot melt welding machine

09 Feb 2022

1. Understand the strength of the company, whether it is independent research and development and production, whether there is technical strength guarantee, to provide guarantee for future equipment maintenance, equipment testing, calibration, system upgrade and whether to buy equipment accessories, so as to solve the user's worries. 2. Find out whether there is after-sales service and related service measures, whether there is a nearby service outlet or a quick solution without a nearby service outlet, and relevant emergency measures. 3. Whether the basic three elements of a qualified equipment "pressure, time, temperature" are accurate, the displayed value should match the actual output value, and whether it meets the requirements of the national standard. (The total welding pressure is equal to the drag pressure plus the theoretical welding pressure; the crimping time, heat absorption time, switching time, gradual rise time and cooling time must meet the requirements; the surface te...

What are the characteristics compared to punch hydraulic presses

27 Jan 2022

1. The hydraulic press is easy to obtain the maximum pressure Since the hydraulic press adopts hydraulic transmission and static pressure, the power equipment can be arranged separately, and multiple cylinders can work together, so a large tonnage hydraulic press can be manufactured. The crank press is limited by the strength of the crank connecting rod, so it should not be made very large. 2. The hydraulic press is easy to obtain a large working stroke Hydraulic presses can easily obtain a large working stroke and can exert full pressure at any position of the stroke. Its nominal pressure is stroke independent and can be stopped and returned anywhere in the stroke. In this way, it is very convenient for processes that require a long working stroke (such as deep drawing), as well as installation of molds, preloading, sub-loading or troubleshooting. 3. The hydraulic press is easy to get a large working space Because it does not have a huge mechanical transmission mechanism, and the work...

Measures that should be paid attention to to prevent the oil temperature from being too high in the hydraulic press

22 Jan 2022

1. Use hydraulic oil with a suitable viscosity. The viscosity recommended by the equipment manufacturer has been proved to be the best. Using Arino with high viscosity, especially in areas with relatively low ambient temperature, will cause an increase in flow friction and overheating. produce. ​​ 2. If there is a hose in the system, it should be clamped and positioned securely. Changing a hose too close to a hot spot can cause the hose to overheat, causing the fluid to pass through it to overheat, so avoid using a hose that's undersized and make sure the hose doesn't have sharp bends. , this will also increase the friction of the oil flow, resulting in an increase in the temperature of the oil ​​ 3. When the pump, hydraulic cylinder and other hydraulic components are worn out, they should be replaced in time. Because the worn components will cause an increase in leakage, the pump will output full flow for a long time, and the oil will cause a large pressure drop through the narrow lea...

Brief introduction to the installation of hydraulic press cooler

19 Jan 2022

1. The hydraulic press cooler is installed at the overflow port of the main overflow valve. The characteristics of this installation method are: the hot oil generated by the relief valve is directly or cooled, and it is not affected by the impact pressure of the system, the one-way valve plays a protective role, and the stop valve can directly return the hydraulic oil to the oil tank when it is started. 2. The cooling is installed on the main oil return road. The characteristics of this installation method are: the cooler is directly installed on the main oil return road, and the cooling speed is fast, but when the system circuit has an impact pressure, the cooler is required to withstand higher pressure. 3. Independent cooling circuit. The advantage of an independent cooling circuit is that; a separate hydraulic pump passes the hot working medium to the cooler, which is not affected by hydraulic shocks. Large equipment or hydraulic systems with serious heat generation are usually equi...
