21700 Battery Can Punching Machine

21700 Battery Can Punching Machine（LTBT80）, 800 kn open two-point press is a new type of high-performance open fixed table press in the market. Its basic structure is developed on the basis of digesting and absorbing the latest technologies from Taiwan and Japan. It is an upgraded product developed for the structural adjustment of traditional pressure machines. Beautiful appearance, low noise, high reliability, obvious energy-saving effect, simple operation and convenient maintenance. The products are equipped with HMI color LCD touch screen, PLC programmable control device, hydraulic overload protection device, pneumatic balance device, pneumatic friction clutch brake, frequency conversion speed regulation technology and progressive thin oil lubrication device. The rigidity of this series of products is higher than the grade a requirements of the national standard, and the accuracy is manufactured according to the grade 1 accuracy of the Japanese standard, which is better than the national standard.

1: Mechanical part

The fuselage of this type of open two-point press adopts an integrated structure and is welded by Q235B steel plate. After welding, it can ensure the stiffness and strength of the fuselage after stress relief treatment and surface shot blasting treatment.

2: Guide rail

The 21700 Battery Can Punching Machine（LTBT80）guide rail adopts six sided rectangular guide rail with adjustable gap. The lower surface of the guide rail is equipped with oil collecting device to return the lubricating oil to the oil tank for recycling after filtration.

3: Transmission system

The 21700 Battery Can Punching Machine（LTBT80）transmission system adopts hyperbolic shaft transmission. The crankshaft is placed longitudinally and the fulcrum distance is short to ensure that the crankshaft has very good stiffness. A gear pair is arranged inside the transmission box, the gear shaft is made of alloy steel, the big gear is a welded gear, and the rim and hub are rolled by a ring roller at high temperature, and then subjected to corresponding heat treatment to ensure service life; The main gear and gear shaft are grinded by precision gear grinding machine to ensure stable transmission; The gear pair is enclosed in the oil pool, with low noise, compact structure and reasonable layout.

Pneumatic friction clutch brake is adopted, and the core parts such as internal bearing, friction plate and sealing ring are all famous brands. The flywheel has been tested for balance performance before assembly, and assembly can be carried out only after it is qualified to ensure stable transmission, flexible action and reliable performance.

All copper bearings and guide rails are made of copper alloy.

4: Slider

The 21700 Battery Can Punching Machine（LTBT80）sliding block adopts Q235B steel plate welded box structure with sufficient strength and stiffness to bear pressure. Conduct overall tempering treatment after welding to eliminate internal stress; The guide way adopts six sided rectangular guide rail, which has strong anti eccentric load capacity. An adjustable guide rail pressing plate is set on the machine body, and the clearance between the left and right guide rails is adjusted with push-pull bolts to ensure the retention of accuracy.

The die height of the slider is adjusted electrically. The die height can be adjusted only when the slider is at the upper or lower dead center. It adopts worm gear transmission, and the slider position measurement method adopts electronic and digital display. The reading accuracy is 0.01mm. It will stop automatically at the upper and lower limit positions. The ball head screw is nitrided and the ball bowl is copper coated, which has high wear resistance.

The sensitive hydraulic overload protection device is adopted to unload 10% of the rated tonnage, and the sliding block movement stops automatically. The protection stroke is more than 1.5 times of the nominal force stroke to ensure the safety of the machine tool and die. The overload pump is a complete set of imported brands, and the recovery time of overload protection is less than 60 seconds.
