Machining diameter of HTIll series machine is $1600-6300mm, and load bearing is 32-500 tons. Overall layout adopts structure of carriage bed separated form work- piece bed, X and Z axis of carriage adopt hydrostatic guide way to realize car- riage is without mechanical wear and stable moving. Wide bed guide way with strong rigidity is more suitable for heavy cutting and high precision machining.

Adopt design and manufacturing technology of oversized table, with maximum diameter of 12.5m and load capacity of 800t. The table adopts hydrostatic guide way in axial direction and double row cylindrical roller bearing in radial direction. Table precision can be much higher than standard after the technology adjustment. The hydraulic system of table is equipped with oil cooler to control the temperature rise of each part and obtain stable precision. Oil film, oil temperature, and flow detection technology to protect the long-term smooth operation of table.

The crossrail is optimized by finite element calculation, which has a large stiffness reserve. After multi-aging and reverse deformation processing, the long-term stability precision is obtained. Synchronous protection device is mounted on elevation mechanism with feature of safe and reliable.

Each shaft of railhead adopts hydrostatic guide way to realize all moving parts of the workpiece have high rigidity of oil film floating, with feature of almost no friction, high sensitivity, good vibration resistance and good precision retentivity. The forged steel quenched ram is equipped with double balanced oil cylinder, the motor load is homogeneous, which offset the bending moment of oil cylinder acting on ram and the deformation.

Advantages:

Feed Mechanism: With the grinding characteristics of centerless grinder, this machine adopts fixed arm design, which effectively solves the difficulty of processing long bars.

For long bars of the same diameter, the user does not need to adjust the position of the material stand at the same time as in conventional equipment, but only needs to command the feeding of the grinding wheel and adjusting wheel based on the CNC system.

When changing long bars of different diameters, the machine also solves the problem that traditional equipment needs to adjust the horizontal position of the material frame every time with a bracket. It only needs to adjust the height of the vertical direction of the material frame and bracket. Thanks to the numerical control system, the complexity of adjustment is greatly reduced, and the production efficiency is improved.

Guide wheel frame and grinding wheel frame: The spindle adopts front and rear double bearing design, and the front end of the wheel uses a cylindrical inner tapered roller bearing with efficient bearing and 3um radial runout accuracy, and the rear end of the spindle has 5um accuracy.

The front bearing of the main shaft is fixed on the front end cover, and the bearing bush with dynamic and static lubrication is used to improve the rigidity in the machining process, greatly reduce the error phenomenon, and ensure the long service life of the adjusting wheel. Clamp guide wheel bearing spindle and spindle taper (1:5) in the spindle, and the mounting scheme of the left screw nut.

Machine feature:

The bending machine works with hydraulic drive. According to the actual situation, the stroke of the slider can be adjusted by programming to adapt it to the processing of different plate thicknesses, while reducing noise and creating a comfortable working environment. At the same time, according to the sheet thickness and type, as well as the feeding speed and distance, and other factors, set the appropriate top dead center position in the program, minimize the slider stroke, and eliminate the slider stroke time by parameterization, thereby increasing the bending frequency.

• World-class CNC system, with AC digital servo motor, high speed and good reliability;
  
  
• The main pneumatic components, electrical components and hydraulic actuators are used by world famous brands to improve the performance of the machine tool;
  
  
• Monolithic beam structure increases rigidity and promotes precise positioning. When running at high speed, the performance and accuracy are stable.
  

This year, our company has successfully delivered a complete steel grating welding production line, the whole line includes: main welding machine, metal carrier strip feeding mechanism, twisted bonding bar feeding mechanism, servo pushing mechanism, pushing mechanism, rack lifting platform, roller assembly, hydraulic system, electrical control system, water cooling system, water pressure, device alarm, etc.

Advantages:

• Using manual feeding or automatic secondary feeding method, the button steel in the large hopper is automatically sent to the secondary hopper.
• Then the steel button is guided to the two blocks of the slider by a ratchet, and the square steel in the block is moved to the main machine for welding to the welding zone by moving the slider.Flat steel plate clamping and feeding mechanism: when the steel grate is welded, a new flat steel plate can be placed on this mechanism. The grate is welded, the new flat steel is sent to the electrode for a new round of welding, which can greatly reduce the idle speed of the machine. It takes time and labor to send flat steel to the main electrode for this process.
• Flat steel sheet storage rack: after the flat steel sheet is unloaded, the "flat steel sheet clamping and feeding mechanism" clamps the trolley to move the flat steel sheet forward, and press the roller assembly to reduce the friction of the steel grate against the frame.
