Embodiment 1

[0046] Such as figure 1 , figure 2 and image 3As shown, the texturizing knife of this embodiment is mainly composed of the handle 1 and the cutting part. The handle 1 and the cutting part are integrated, which eliminates the defects such as the decrease in hardness of the blade and the generation of cracks caused by welding. The outside of the handle 1 is in the shape of a cuboid. The cutting part is arranged at one end of the handle 1 and is located on the upper side of the end. In the cutting part, the planar rake face 2 intersects with the main flank face 4 which is an arc surface. The arc-shaped main cutting toughness 3 is formed, and the angle range of the arc angle γ of the main cutting toughness 3 is 90°~180°. The setting of the arc angle γ makes the main cutting toughness 3 when texturing the rubber roller, Grinding with the rubber roller during the operation of the lathe without damaging the surface of the rubber roller, changing the original turning purpose of th...

Embodiment 2

[0062] In this embodiment, the materials of the textured knife and the orange-peel rubber roller used are the same as in Example 1, and four orange-peel rubber rollers with a specification of Φ250×1500mm are also produced, the difference is that:

[0063] In this embodiment, in the orange-peel-shaped rubber roller production step, in the rubber roller wear debris: take the diameter of the rubber roller as a benchmark, control the lathe speed to 330 rpm and the cutting speed to 1.1mm / rev, and the amount of feed at this time is the same as that of the rubber roller The density of the orange peel is inversely proportional, and the cutting amount is controlled to 0.22mm to produce an orange peel rubber roller with uniform density.

[0064] The relevant test record data of 4 pieces of orange peel rubber rollers are as follows in Table 3:

[0065] table 3

[0066]

[0067] As can be seen from the above table 3, adopting the material of the texturing knife and the orange peel rub...

Embodiment 3

[0069] Such as figure 2 , image 3 , Figure 4 As shown, on the basis of Embodiment 1, the texturizing knife of this embodiment also includes a secondary cutting toughness 5 and a secondary flank 6, wherein the secondary flank 6 is a smooth plane connected to the Between the two ends of the main flank 4 and the handle 1; the intersection of the rake face 2 and the auxiliary flank forms a secondary cutting toughness 5, which is straight and connected to the two ends of the main cutting toughness 3 and the Between the handle 1, after the main cutting toughness 3 of the texturing knife is worn, the main cutting toughness 3 can be reground along the secondary cutting toughness 5, so that the service life of the texturing knife can be extended.

[0070] Next, use the above-mentioned texturing knife to make four pieces of orange-peel-shaped rubber rollers with a specification of Φ840×1600mm. The specific production process is as follows:

[0071] (1) Preparation of sizing materi...

Abstract

The invention discloses a roughening knife and a method for manufacturing an orange-peel-shaped rubber roller, and belongs to the field of turning of rubber rollers. The roughening knife comprises a knife handle and a cutting part. The cutting part is located at one end of the knife handle and comprises a front knife face, a main cutting blade and a main rear knife face. The included angle betweenthe front knife face and the horizontal plane where the knife handle is located is alpha. An intersecting line between the front knife face and the main rear knife face is the main cutting blade, andthe main cutting blade is in an arc shape. The main rear knife face is an arc face. The included angle between the main rear knife face and the horizontal plane where the knife handle is located is beta. By adoption of the roughening knife, orange-peel-shaped rubber rollers with different concave-convex degrees or different densities can be manufactured without damaging the surfaces of the rubberrollers.

Description

technical field [0001] The invention belongs to the field of rubber roller lathe processing, and in particular relates to a texturing knife and a method for making orange-peel-shaped rubber rollers. Background technique [0002] With the rapid development of steel and other industries, the requirements for the use of rubber rollers are diversified. In the past, rubber rollers were processed into smooth surfaces, with a roughness below 12.5, and rubber rollers with grooves can no longer meet the needs of steel and other industries. In the current iron and steel industry, the speed of the rubber roller is relatively high, generally 500-800mm / min. At this speed, the relative slip between the rubber roller and the thin steel plate is prone to occur, the rubber roller is not running smoothly, and the thin steel plate will also fluctuate. Therefore, it is necessary to texturize the surface of the rubber roller into evenly distributed concave-convex shape, that is, orange peel shap...
