Abstract

A cold rolling production line for the inner and outer rings of a bearing comprises a high-speed pier forging machine, a cold rolling machine, bearing inner and outer ring lathes, a quenching furnace and bearing inner and outer ring grinding machines, wherein the high-speed pier forging machine is placed in a first workshop, the cold rolling machine and a plurality of bearing inner and outer ring lathes are placed in a second workshop, the quenching furnace is placed in a third workshop, and a plurality of bearing inner and outer ring grinding machines are placed in a fourth workshop, wherein rails are laid between the first workshop and the second workshop, the second workshop and the third workshop, and the third workshop and the fourth workshop, and conveying dollies run on the rails. The cold rolling production line substantially reduces waste of raw materials, lowers production cost, improves product quality, reduces lathing workload, and improves work environment through isolation.

Description

Bearing enclose cold roll production line

Technical field:

The utility model relates to Production of bearing technical field, more specifically to a kind of production line that adopts cold roll technology to carry out bearing enclose production.

Background technology:

General following production technology and equipment, 1 of adopting of existing bearing enclose production), use cutting machine to cut into block blank Steel Pipe For Bearing; 2), use lathe to machine block blank; 3), the blank after Vehicle Processing is quenched on glowing furnace; 4), on grinding machine, grind processing after get product.Its weak point is: the bearing steel foam amount of 1, using cutting technique to cut out is large, can cause a large amount of waste of raw materials like this.2, the bearing enclose blank by cutting is when machining, and the communication on bearing enclose must can moulding by lathe turning, has caused again raw-material turning to waste.

Utility model content:

The new U-shaped object of this practicality is exactly the deficiency for prior art, and provide a kind of bearing enclose cold roll production line, it greatly reduces raw-material waste, reduced production cost, improved product quality, reduce the workload of Vehicle Processing, by the mode of isolation, improved working environment simultaneously.

Adopt high speed pier to forge machine and directly bearing steel bar produced to bearing blank,

Technology solution of the present utility model is as follows:

Bearing enclose cold roll production line, comprise high speed pier forging machine, cold grinding, bearing enclose lathe, glowing furnace and bearing enclose grinding machine, high speed pier forging machine is placed in the first workshop, cold grinding and some bearing enclose lathes are placed in the second workshop simultaneously, glowing furnace is placed in separately the 3rd workshop, some bearing enclose grinding machines are placed in the 4th workshop, between the first workshop and the second workshop, between the second workshop and the 3rd workshop, be all equipped with track between the 3rd workshop and the 4th workshop, on track, walking has travelling bogie.

The beneficial effects of the utility model are:

1, it adopts high speed pier forging machine to use bearing steel bar directly to produce bearing enclose failed part, by cold grinding direct cold roll on bearing enclose, goes out raceway groove, greatly reduces raw-material waste, has reduced production cost, has improved product quality.

2, it has reduced the workload of Vehicle Processing, has improved working environment by the mode of isolation simultaneously.

Accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model.

The specific embodiment:

Embodiment: as shown in Figure 1, bearing enclose cold roll production line, comprise high speed pier forging machine 1, cold grinding 2, bearing enclose lathe 3, glowing furnace 4 and bearing enclose grinding machine 5, high speed pier is forged machine 1 and is placed in the first workshop 6, cold grinding 2 and some bearing enclose lathes 3 are placed in the second workshop 7 simultaneously, glowing furnace 4 is placed in separately the 3rd workshop 8, some bearing enclose grinding machines 5 are placed in the 4th workshop 9, between the first workshop 6 and the second workshop 7, between the second workshop 7 and the 3rd workshop 8, between the 3rd workshop 8 and the 4th workshop 9, be all equipped with track 10, on track 10, walking has travelling bogie 11.

Operation principle: it is forged on machine and cold grinding and add and produce without waste material man-hour at high speed pier, mode by cold roll processes communication on bearing enclose simultaneously, when Vehicle Processing, lathe just carries out processing seldom to bearing failed part, so saved raw material, the inner quality of bearing enclose simultaneously processing by cold roll mode is more closely knit, so product quality is better.

This production line is placed in a workshop by high speed pier forging machine, and glowing furnace is placed in separately to a workshop, and bearing grinder workshop is placed in to a workshop, can avoid the noise of equipment generation and influencing each other of high temperature, thereby improve working environment.
