1, adopting compressed air is power, the small-sized plate shearing machine of QJ series be utilize compressed air for power specially at the small-sized plate shearing machine of thin plate (thickness is below 2.5mm).The parts of its pneumatic part all adopt the brakes accessory of automobile, and its security, persistence and reliability can be guaranteed, and blade is regular production product.

2, miniature pneumatic plate shearing machine lathe bed middle part indent is reserved the blanking space.Small-sized plate shearing machine has following characteristics: the model QJ-510 of QJ series * 600:510 is meant the length 510mm of scissors, 600 are meant that the Breadth Maximum of the iron sheet of cutting is 600mm, can extend as required or shorten in the production afterwards of this width, iron sheet can be cut out any length in the wide scope of 600mm, its mechanization degree is higher, and working (machining) efficiency is higher, one people can operate, simultaneously molding mass smooth, can not tear the limit open, and shear precision height, scale error is less; Particularly when cutting out size when big, labor strength obviously lowers; Cut out same specification sheet material quantity when big, can use scale, speed is faster.

3, along with the fierceness day by day of market competition, the prices of raw and semifnished materials go up, and product price can rise, and profit margin is little.Large-scale equipment investment is higher, energy resource consumption is big, cost is higher, manual press cut that labour intensity is big, at the bottom of the efficient, low precision, this miniature pneumatic plate shearing machine has been filled up large-scale plate shearing machine to manual blank of pressing between cutting, can make process reduce 1-2 people, can reduce expenses every year about 20,000 yuan like this, its economic benefit is more remarkable.
