Abstract
The utility model discloses a rolling structure of high pressure rolling crusher, which comprises a roll sleeve (1), blind holes (2) evenly distributed on the circumference of the external surface of the roll sleeve and cemented carbide pegs (3); the cemented carbide pegs (3) and blind holes (2) on the roll sleeve (1) are a clearance combining structure, and connected as a whole with connecting media. The utility model is of reasonable design, a simple structure and easy processing. As a connection of the cemented carbide pegs and blind holes on the surface of the roll sleeve is designed into a clearance combination, and the cemented carbide pegs and blind holes on the surface of the roll sleeve are connected as a whole with high strength adhesive, once the cemented carbide pegs are worn or fractured when used, the pegs can be removed through a method of local heating for replacement. Therefore service life of the roll sleeve is greatly prolonged, use cost is effectively reduced; in addition, repair time is shortened, and integral operating rate of equipment is improved. The utility model is applicable to industries of mine, metallurgy, building material, etc.
Description
Technical field
The utility model belongs to the broken machine technology of high pressure roller field, and what relate generally to is a kind of roller structure of high pressure rolls.Be applicable to industries uses such as mine, metallurgy, building materials.
Background technology
At present, the roller structure of domestic high pressure rolls (also being high-pressure roller mill, high pressure roll press) is to be press-fitted the hard alloy columnar nail on roller shell mostly, and promptly in roller shell Surface Machining column type blind hole, the post nail is shaped as column type, itself and blind hole are over-surplus fit structure, adopt press-fit approach to install.Because post nail phenomenon of rupture can often appear in the roller structure of this structure in actual applying working condition,, can cause whole roller shell actual effect in case the fracture of post nail just is difficult to change.Not only influence is produced, and can increase use cost.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of roller structure of high pressure rolls.Solve the replacing problem of post nail fracture, prolonged the service life of roller shell, reduced use cost.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: the hard alloy columnar nail is designed to matched in clearance with the roller shell surface being connected of blind hole, and described hard alloy columnar nail connects as one by medium with the blind hole on roller shell surface.
The utility model is reasonable in design, and is simple in structure, handling ease.Because it is designed to matched in clearance with the hard alloy columnar nail with the roller shell surface being connected of blind hole, and it connects as one in the future to adopt high strength bonding glue, like this, in case wearing and tearing of hard alloy columnar nail or fracture in use just can be taken out the post nail by the method for local heat and be changed.Thereby prolonged the service life of roller shell greatly, effectively reduced use cost, shortened the repair time, improved equipment overall operation rate.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, roller shell, 2, blind hole, 3, the hard alloy columnar nail.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the described pressure roller of present embodiment is the pressure roller of using on the high pressure rolls.This pressure roller is made of roller shell 1 and hard alloy columnar nail 3, is evenly equipped with blind hole 2 on the outer surface circumference of roller shell 1, and the blind hole 2 on described hard alloy columnar nail 3 and the roller shell 1 is the matched in clearance structure, and adopts the connection medium that it is connected as one.The agent of the described connection medium of present embodiment high strength bonding.During use,, can take out and change by the local heat method in case wearing and tearing or phenomenon of rupture appear in hard alloy columnar nail 3.
Claims (2)
1. the roller structure of a high pressure rolls, comprise blind hole (2) uniform on roller shell (1) and the outer surface circumference thereof and hard alloy columnar nail (3), it is characterized in that: the blind hole (2) on described hard alloy columnar nail (3) and the roller shell (1) is the matched in clearance structure, adopts the connection medium to connect as one.
2. the roller structure of high pressure rolls according to claim 1 is characterized in that: described connection medium is the high strength bonding agent.
