Electric I-beam bending machine, hydraulic I-beam cold bending machine, CNC I-beam cold bending machine, I-beam cold bending machine, I-beam arch bending machine, I-beam bending machine, I-beam bending machine, I-beam bending machine. Tdbs250 numerical control I-beam cold bending machine] application scope: the cold bending machine is mainly used for arched winding, variable diameter and fixed angle bending of I-beam, miner's steel, U-shaped steel, C-shaped steel, angle steel, channel steel, track, square steel, steel pipe, etc. By using digital encoder programming, the positioning of hydraulic control system is accurate, and the bending section steel is formed automatically at one time, with high efficiency and convenient operation. It is widely used in the construction of tunnels, subways, hydropower stations, underground caverns and other industries. It is an ideal equipment for manufacturing steel arch frame. Working principle of tdbc250 numerical control I-beam cold bending machine: (1) when working, push the required cold bending section steel between the two active rollers by the portal bracket of the auxiliary system, and start the hydraulic system to make the hydraulic cylinder push the dovetail groove and cold-formed roller cold-formed steel. When the required radian is reached, close the hydraulic system and start the mechanical transmission system, Make the driving roller rotate and drive by frictionThe section steel moves forward smoothly and slowly, thus realizing continuous cold bending operation. (2) At the end of cold bending, close the mechanical transmission system and start the hydraulic system to retract the hydraulic cylinder. The cold-formed steel can be placed on the portal bracket of the auxiliary system. This kind of cold bending operation ensures the strength of material, improves the quality of supporting steel arch frame, greatly improves the work efficiency, and the operation is simple and clear. Compared with the press, the cold bending machine has good working performance. 5 necessary factors and 2 notes for selection of numerical control I-beam cold bending machine (1) diameter of three top rollers: thin, easy to slip due to small contact surface; easy to deform when bending non-standard steel. (2) Cylinder diameter and stroke: the diameter and stroke determine the pressure and the adjustable bending radius. (3) The thickness of the steel plate of the platform and the quality of the framework determine whether the large steel is deformed or not. (4) The power of the motor and the quality of the reducer. (5) Manufacturer's production scale and service. Notice 1: type, model and material of the steel to be bent; note 2: bending radius: to find out whether the bending radius conforms to the cold bending coefficient of steel. Each kind of steel has its own cold bending coefficient. If it exceeds the cold bending coefficient, the steel will deform, the internal structure of steel will change, and the quality of steel will also be reduced. Tdbc250 CNC I-beam cold bending machine maintenance and maintenance 1. After the new machine runs for 50 hours, check and lock the bolts to see if they are loose. 2Change hydraulic oil after 100 hours of operation (about 15 days) of new machine; 3. Change reducer oil after 200 hours of operation of new machine; 4. Change hydraulic oil and reducer oil once a year; 5. Add grease to pressure shaft every shift tdbc250 after-sales service of I-beam cold bending machine: 1 According to the construction feedback of major construction sites, the quality of our cold bending machine is better than that of other businesses in the market in terms of steel plate thickness, roll diameter, cylinder stroke, including motor and reducer selection. At the same time, we continue to absorb the feedback from users at the construction sites across the country and constantly improve our products. It can be said that our products are in the hearts of customers after purchasing You are welcome to consult and understand. You will not be disappointed. Tunnel special steel mesh welding machine and numerical control tunnel steel mesh multi-point welding machine are the key scientific research projects of Yancheng Haibin stone Da Bangcheng Technology Co., Ltd. adopting synchronous control technology, the separate control welding and welding time are controlled by digital programming system, and the input panel is touch screen or key, so the operation is more intelligent and reasonable, and has one-time pressing and welding in batches The welding power is electric, using step motor hopper, brake motor driving car let off, step motor driving trolley pulling net. Both warp and weft wires are straightened and cut by straightening machine, vertical wires are placed manually, and horizontal wires are automatically dropped. The welding machine can weld 8 points at a time, the minimum distance between two points is 50 mm, and the diameter of weldable reinforcement is 6 ~ 8Welding requirements, is the construction department prefabricated reinforced concrete wall panel welding steel special equipment. The performance characteristics of the welding machine for the reinforcement mesh of the tunnel support net: 1. Each group of transformers is controlled by a separate microcomputer, which is pressurized once and welded many times, making the welding more reliable, more stable, faster and more intelligent. 2. This equipment adopts the mechanical resistance welding method, the welding pressure is uniform, the welding spot is firm and stable. 3. The welding electrode head is made of high quality chromium zirconium copper material, with long service life and low production cost. 4. The latest NC welding can meet the requirements of high speed continuous welding of 5mm-8mm steel wire, and there is no phenomenon of open welding and missing welding. 5. The whole operation only needs 2-3 people, which greatly reduces the labor cost. 6. PLC programming control, humanized operation interface, easy to operate and master. 7. The mesh size is adjusted by numerical control, and all welding parameters and production data are set conveniently and quickly. Technical parameters of tunnel reinforcing mesh sheet welding machine: mesh length: 1.2m × 2m or 1.2m × 3m or 1.5m × 3M welding wire diameter: 4-8mm welding aperture: 100 * 100 mm number of warp wires (welding points): 6 or 8 or 10 power supply: 380V, 50 Hz welding speed: 35 (row / min) overall weight: 2200kg special specifications are customized according to customer requirements!
