Technical Field

The invention relates to the field of machinery, in particular to a shot blasting wear-resistant roller way.

Background

The protection of the roller way in the shot blasting chamber is always the problem of the attention of shot blasting equipment manufacturers, most of the commonly used protection devices are provided with a set of protective sleeves made of wear-resistant materials outside the roller way at present, and thus the whole roller way is equivalent to wearing one layer of armor and adding one layer of protective sleeves. However, after a period of throwing, the sheath is often worn, and the sheath needs to be replaced, even the whole roller way needs to be replaced. The workload of replacing the roller way is very large, and the working environment of all shot blasting equipment is a very dirty environment, so that the replacement is not easy, the maintenance man-hour and the maintenance cost of equipment use manufacturers are increased, and the equipment shutdown loss of the equipment use manufacturers is increased.

Disclosure of Invention

In order to overcome the defect that the conventional shot blasting roller way protective device is easy to wear and needs to be replaced frequently, the invention provides the shot blasting wear-resistant roller way which is good in wear resistance and long in service life and greatly prolongs the replacement period.

The technical scheme of the invention is as follows: the shot blasting wear-resistant roller bed comprises two shaft heads which are bilaterally symmetrical, wherein baffles are fixed on the outer walls of the shaft heads, a plurality of side cross beams are connected between the left baffle and the right baffle, and shaft end baffles are fixed at the shaft ends of the inner sides of the shaft heads; the side cross beam penetrates through the shaft end baffle and the supporting plate.

A central cross beam is connected between the two shaft end baffles and penetrates through the supporting plate.

The diameter of the shaft end baffle is larger than that of the supporting plate.

The number of the side cross beams is more than 2.

The supporting plate, the side beams and the central beam are made of the same material and are one of Mn13, X120Mn12, 1.3401 and Mn15Cr 1.

The invention has the following beneficial effects: by adopting the scheme, the squirrel-cage type wear-resistant roller way is formed by the baffle, the shaft end baffle and the side beam, the structure is simple, the weight of the equipment is reduced, the wear is reduced, and meanwhile, the problem that steel shots are prevented from being pressed into workpieces due to the fact that the support rings are needed when heavy steel plates or heavy workpieces are thrown is solved. The invention of the squirrel-cage type wear-resistant roller way is a thorough revolution of the wear-resistant roller way, has long service life and improves the yield and efficiency of users.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1 to 3, the shot blasting wear-resistant roller bed comprises two shaft heads 1, wherein the two shaft heads 1 are bilaterally symmetrical and are connected with a driving mechanism. The outer wall of the shaft head 1 is fixedly provided with a baffle 2, the baffle 2 is sleeved on the shaft head 1, and a plurality of side beams 5 are connected between the left baffle 2 and the right baffle 2. Shaft end baffles 3 are fixed at the shaft ends at the inner sides of the two shaft ends 1, the shaft end baffles 3 are parallel to the baffles 2, and a central cross beam 6 is connected between the two shaft end baffles 3. The shot blasting wear-resistant roller way also comprises a plurality of supporting plates 4 parallel to the baffle 2, and the distance between the supporting plates 4 is determined according to the length of the roller way and the requirement of a thrown workpiece. The side beam 5 penetrates through the shaft end baffle 3 and the support plate 4, the side beam 5 is welded and fixed with the shaft end baffle 3 and the support plate 4, and the central beam 6 penetrates through the support plate 4 and is welded and fixed with the support plate 4. The diameter of the shaft end baffle 3 is larger than that of the support plate 4, the shaft end baffle is connected with the shot blasting chamber, and the two shaft end baffles 3 seal the shot blasting chamber to play a role in protection so as to protect the shaft head 1 from being thrown. The number of the side cross beams 5 is larger than 2, the diameter and the number of the bars are selected according to the working condition of practical application, and the bars are uniformly distributed on the working surface of the supporting plate 2 and are not limited to be on a concentric circle. The diameter of the central beam 6 is selected according to the mechanical design of the working condition of practical application, and the central beam 6 can be omitted under the working condition of particularly light load. The supporting plate 4, the side beams 5 and the central beam 6 are made of the same material and are one of Mn13, X120Mn12, 1.3401 and Mn15Cr 1.

The shot blasting wear-resistant roller way adopts wear-resistant steel to manufacture the squirrel-cage wear-resistant roller way, fundamentally changes the original roller way protection form, has simple structure, lightens the self weight of equipment, reduces wear, avoids steel shots from being pressed into workpieces, has long service life and prolongs the replacement period.
