How to use the hot melt butt welder

01 Nov 2019

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 detached 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 tool input; whether the heating plate meets the requirements (Whether the coating is damaged); trial operation of milling cutters and oil pump switches, etc. Then put the kava with the same pipe specifications into the rack; set the heating plate temperature to the welding temperature (the welding temperature of the polyethylene pipe channel 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. 2, welding W...

Welding positioner use and technical requirements

26 Oct 2019

The positioner is a special welding aid that is suitable for the welding displacement of the rotary work to obtain the ideal machining position and welding speed. It can be used together with the operating machine and welding machine to form an automatic welding center, and can also be used for workpiece displacement during manual work. The table rotates with stepless speed regulation of the frequency converter, and the speed regulation precision is high. The remote control box can realize the remote operation of the worktable, and can also be connected with the operation machine and the welding machine control system to realize the linkage operation. The welding positioner is a universal and efficient welding equipment for ring seam welding. It can be equipped with a welding machine such as a argon arc welding machine (filled or unfilled), a gas metal arc welding machine (C02/MAG/MIG welding machine), a plasma welding machine, etc., and can be combined with other machines to form an a...

Wear plate surfacing machine working principle

19 Oct 2019

The wear-resistant composite steel plate is processed by uniformly welding a layer of wear-resistant alloy on the surface of the ordinary titanium steel plate with a special high-hardness arc self-shielding welding wire for the wear plate. Its material: Q235 + wear plate alloy. Surfacing and wear-resistant composite steel is a common material in industrial and mining. It is a new type of alloy lining wear-resistant material, which has been widely used in industrial production. Its surfacing and wear-resistant composite steel plate has high wear resistance, good impact resistance, good corrosion resistance and high price performance. It is a kind of surfacing equipment because of its characteristics and long service life. The working principle is that the workpiece is placed on the workpiece carrier, and the welding arm equipped with the arc welding head is horizontally and vertically moved on the gantry, so that the welding tip on the head is aligned with the weld, and then the gantry ...

Welding roller frame working principle and installation precautions

12 Oct 2019

The welding roller frame drives the rotation of the cylindrical (or conical) weldment by the friction between the weldment and the active roller. Mainly used on some large machines in heavy industry. So today we focus on what needs to be paid attention to when installing the welding roller frame! 1. Before welding the roller frame When using, the roller should be in full contact with the workpiece. It is strictly forbidden to contact the weld or the sharp part. At the same time, when the workpiece is hoisted, it is strictly prohibited to hit the roller to prevent the roller or other parts from being damaged. If the equipment is not fixed, the strong impact may cause the whole Machine subversion. 2, when the welding roller frame starts Adjust the welding roller frame from low speed to high speed at the start, when changing the steering, the motor can be switched after the motor is stopped, otherwise the motor will be burnt. During operation, it is strictly forbidden to separate the man ...

Welding roller frame maintenance and cleaning

09 Oct 2019

Everyone knows how the welding roller frame works. The welding roller frame drives the rotation of the cylindrical (or conical) welding element by the friction between the welding element and the driving roller. Let us take a look at the maintenance work of the welding roller frame today. Maintenance procedure 1. Check and remove the obstacles on the machine before welding, and need to be used and kept by special personnel. Do not touch the oil and fire type of the roller frame. The oil filling holes are often oiled. 2, rolling bearing: through the oil cup on the bearing cover for lubrication, it is recommended to use sodium grease. 3. Transmission gear: For the first time, it is necessary to remove the active gear guard and apply a proper amount of grease on the gear. It is recommended to use sodium grease. During use, the grease can be filled through the oil hole on the gear cover, and foreign matter is strictly prohibited from falling into the gear. 4. Cycloidal pinwheel reducer: Pl...

Single head welding machine

30 Sep 2019

The composition and configuration of the single-head roll welding machine is a machine tool gantry type, which mainly includes gantry, horizontal welding machine, automatic submerged arc welding system, electrical control system and safety protection device. (a) gantry The gantry frame is composed of a column, a beam, a beam moving trolley, and a welding head adjusting carriage. Features: The column is made of two rectangular steel tubes welded and machined. The advantage is that the weight is light, the rigidity is good, the appearance is beautiful, and the column is fixed on the back side of the bed of the horizontal welding machine. (2) Horizontal welding machine The horizontal welding machine consists of a drive head frame, a machine base, a bracket, and a tailstock device. The driving head frame is mounted on the machine base (see the main view at the mounting position). The mounting surface on the base and the mounting surface of the head frame are finished, which ensures the pos...
