Technical field

The invention belongs to roll cutting equipment technical field, and in particular to a kind of novel wheel belt alloy production line slab ingot gear Roller shear.

Background technique

Centre slitting installation is one of the key equipment of aluminum alloy continuous casting production line, and function is will to come from rolling code device Flat aluminium bar cut, flow into next process.Therefore the service life of roller shear, durable tolerance directly influence whether alloy production line Stable operation.The axis of roller shear up and down of existing roller shear is connect and is supported with rack by copper sheathing, and copper sheathing is mainly by self-lubricating, in height It is very easy to abrasion under warm environment, aluminium embryo is caused to be cut constantly, just needs within usual 2 months or so to shut down adjusting scissors size or more Recopper set, shutting down replacement needs 4 hours, impacts to continuous production；Meanwhile the transmission gear of gear-box is using straight-tooth Wheel is prone to wear under high temperature and high speed operating, noise is caused to increase, and can also generate long stub in shearing, influence aluminium bar stacking etc. Subsequent handling.

Therefore, a kind of not easy to wear, stable drive is researched and developed, equipment life extends, and the novel wheel belt for reducing shutdown is closed Golden production line slab ingot gear roller shear is the key that solve the above problems.

Summary of the invention

The purpose of the present invention is to provide a kind of novel wheel belt stable, high-efficient, failure rate is low, maintenance cost is low Alloy production line slab ingot gear roller shear.

The present invention is implemented as follows: including box body, roller shear axis is provided in box body, roller shear axis includes being arranged in parallel Upper roller shear axis and lower roller shear axis, lower roller shear axis connect with driving motor, and the scissors disk matched, scissors are provided on roller shear axis Blade is symmetrically arranged on disk, the roller shear axis is connect by bearing with box body, and the upper roller shear axis and lower roller shear axis pass through Isometrical cylindrical helical gear drive connection.

Beneficial effects of the present invention:

1, using needle bearing, by sliding Variable roll, friction reduces the friction between roller shear axis and box body, reduces abrasion, It greatly reduces maintenance and changes piece number；

2, using helical gears, transmission is more steady, and shock and vibration, noise are also smaller, improves the stationarity of transmission, Transmitting coinsidence is bigger than the registration of spur gear simultaneously, and carrying and shearing force improve；

3, using circulation fuel feeding cooling and lubricating system, box body inner bearing and transmission parts are lubricated and are cooled down, is reduced Abrasion, reduces failure, increases the service life；

Therefore, the present invention has the characteristics that stable, high-efficient, failure rate is low, maintenance cost is low.
