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...

Classification of surfacing equipment

21 Sep 2019

The surfacing equipment can be divided into a double-head (or multi-head) roll surfacing machine, a roll press automatic roll surfacing machine and a single-head roll submerged arc surfacing machine. The equipment configuration of the single-head roll submerged arc surfacing machine is as follows : Single head welding machine body, welding machine head and surfacing welding torch (including carriage), welding oscillating device, submerged arc welding power source, flux recovery system, welding cable assembly (including drag chain) and electrical control system. First, adapt to the workpiece and welding method 1. Workpiece situation: Wheel diameter: 800mm, maximum weight: 500kg Roller maximum diameter: 300mm, maximum length: 1500mm Maximum weight: 1000kg 2. Welding method: submerged arc surfacing 3. According to the requirements of the welding process, different welding processes such as spiral surfacing, step surfacing, swing surfacing and so on can be selected. Preset welding paramete...

Longitudinal seam welding machine in tower

16 Sep 2019

The longitudinal joint welding machine in the tower is mainly used for the automatic welding of the longitudinal joints in the pyramid communication tower and the longitudinal welding of the thin plate or thin-walled cylinder. The operation is simple, the welding work efficiency is high, the weld formation is fast, the workpiece quality is good and the appearance is beautiful. Generous, long-lasting and practical. The head of the longitudinal joint welding machine in the tower has a two-dimensional mechanical tracking mechanism, which can reduce the frequent adjustment of the head due to the error of the cylinder placement. The welding surface of the workpiece is flat, and the maximum gap of the butt weld is less than 1mm and in the workpiece. The surface is free of grease, work without dirt and severe rust. Before the workpiece is welded, the workpiece must be placed on the roller frame before welding. The inner longitudinal joint to be welded is welded to the workpiece before the wel...

The outer longitudinal joint welding machine for tower pole is mainly used for automatic welding of longitudinal joints in pyramid communication towers and longitudinal seam welding of thin plates or thin-walled cylinders. It is easy to operate, has high welding work efficiency, fast weld formation, good workpiece quality and beautiful appearance. Generous, long-lasting and practical. The head of the outer longitudinal joint welding machine of the tower has a two-dimensional mechanical tracking mechanism, which can reduce the frequent adjustment of the head due to the error of the cylinder placement. The welding surface of the workpiece is flat, and the maximum gap of the butt weld is less than 1mm and is in the workpiece. The surface is free of grease, work without dirt and severe rust. Before the workpiece is welded, the workpiece must be placed on the roller frame before welding. The inner longitudinal joint to be welded is welded to the workpiece before the welding at 6 o'clock, an...
