When the used roll forming machine produces steel pipes, the pipe fittings move at a constant speed according to the set speed, and the saw car is stationary relative to the unit before the sawing process. When the steel pipe reaches the set length, the clamping device of the saw car clamps the steel pipe, and the drive mechanism drives the saw car to move with the steel pipe and perform the sawing process until the sawing operation is completed. When the sawing process of the flying saw is completed, the driving device drives the saw carriage to return to the initial position. The reciprocating motion of the saw car is realized by the relative movement of the rack at the bottom of the saw car and the gear fixedly installed on the machine bed system.

Status of insufficient lubrication

In the current gear and rack transmission system of the flying saw, the lubrication between the gear and the rack is mostly achieved by manual and regular application of grease. Manually applying grease on a regular basis is labor-intensive and time-consuming, and the working conditions of the flying saw are complicated, the humidity between the contact surfaces of the gear and the rack is high and the ash content is high, and the grease is difficult to adhere for a long time. The strip bears a large impact force. Once the grease falls off or is not applied in time, the gear and the rack are in direct contact with each other for dry friction, which will not only increase the movement resistance of the equipment, cause energy waste, and increase operating costs; Rack wear.

Frequent maintenance and replacement of gears and racks for used roll forming machine flying saws greatly increase production costs and reduce production efficiency. Before the technical improvement, the gears were replaced once every 2~3 months on average, and the racks were replaced once every 5~6 months; and each time the gears were replaced, 2~3 people worked for 2~3 hours, and it took 2~3 hours to replace the racks. 3 people work for 3~4 hours, and the replacement of the whole set of gears and racks requires 3~4 people to work for 5~6 hours. This does not include the usual repair costs and the production impact of downtime to replace parts. Therefore, solving the problem of poor lubrication of gears and racks is an urgent technical problem for steel pipe manufacturers to solve.

According to the problem of insufficient lubrication of the used roll forming machine flying saw to saw car, we will propose how to improve the lubrication mechanism. For everyone to answer the intractable problems of insufficient lubrication of the used roll forming machine flying saw to saw car.
