Abstract
The utility model discloses a press roll of a sheet metal flattening machine, which comprises a roll body with a cavity, wherein a left-handed shaft and a right-handed shaft are arranged on the left and the right end of the roll body; small holes communicated with the cavity are formed in the side wall of the middle part of the roll body; a passage communicated with the cavity is arranged on the left-handed shaft; and a carburization rigidification layer is arranged on the surface of the roll body, with the depth of 1.1-1.2mm. The press roll has the advantages of wear resistance, long service life, and good flattening effect, and is smooth and indentation-free after being rectified.
Description
Technical field
The utility model relates to a kind of steel plate levelling means, specifically is a kind of sheet metal evener pressure roller.
Background technology
Evener is to be specifically designed to irregular sheet metal, by the extruding of top and bottom rolls with certain thickness band or sheet material, thereby reach the equipment of smooth effect, evener production line: for the cutting to length behind the leveling metallic plate, the production line corollary equipment that belongs to metallurgical equipment, in the prior art, steel plate is in the process of leveling, the steel plate bending can occur by pressure, and the surface of steel plate flatness is damaged easily.Determine the leveling efficient of pressure roller machine the service life of pressure roller.
The utility model content
It is a kind of wear-resistant that the utility model provides, and the life-span is long, flattens effective, antirust, as to correct the smooth smooth-going no impression in back sheet metal evener pressure roller.
The utility model technical solution problem provides following scheme:
A kind of sheet metal evener pressure roller, comprise roll body, it is characterized in that: the two ends, the left and right sides of described roll body are provided with left and right rotating shaft, the inside of described roll body has cavity, and the sidewall at the middle part of roll body is provided with the aperture with cavity UNICOM, described left rotary shaft is provided with passage and is communicated with cavity, and the surface of described roll body is provided with the comentation hardening layer, and described case depth is 1.1-1.2mm.
Described roll body adopts vacuum hardening technology, and hardness is HRC52-HRC54.
The utility model is raw material with the superior alloy steel, and hardened-depth reaches 1.2mm, has stronger wearability; Difference of hardness is less than HRC3, stop the cracking in the use, fallen phenomenons such as piece, eccentric wear, improved the service life of ring mould greatly, in light weight, revolution inertia is little, wear-resistant, life-span is long, in the process of carrying out the steel plate leveling, the surface quality of steel plate is easy to guarantee, can the surface of steel plate crushing not be ruined by pressure roller like this.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of sheet metal evener pressure roller, comprise roll body 1, the two ends, the left and right sides of described roll body 1 are provided with left and right rotating shaft 2,3, and the inside of described roll body 1 has cavity 4, and the sidewall at the middle part of roll body 1 is provided with the aperture 5 with cavity UNICOM, described left rotary shaft 2 is provided with passage 6 and is communicated with cavity, and the surface of described roll body 1 is provided with comentation hardening layer 7, and described hardened layer 7 degree of depth are 1.1-1.2mm, described roll body 1 adopts vacuum hardening technology, and hardness is HRC52-HRC54.
Claims (2)
1. sheet metal evener pressure roller, comprise roll body, it is characterized in that: the two ends, the left and right sides of described roll body are provided with left and right rotating shaft, the inside of described roll body has cavity, and the sidewall at the middle part of roll body is provided with the aperture with cavity UNICOM, described left rotary shaft is provided with passage and is communicated with cavity, and the surface of described roll body is provided with the comentation hardening layer, and described case depth is 1.1-1.2mm.
