Improved accelerated roller

Abstract

The invention discloses an improved accelerated roller comprising a rolling and pressing ring on the outer side and a connecting ring on the inner side. The connecting ring is movably connected to a rotary shaft of a motor, the rolling and pressing ring is provided with a welding groove structure and sleeves a tungsten carbide roll ring structure, one side of the welding groove is provided with a baffling edge structure, the radius of the baffling edge structure is smaller than the rolling radius, namely 0.3 to 0.5mm, of the tungsten carbide roll ring, and the other side of the welding groove is provided with an isolating ring structure sleeving the tungsten carbide roll ring. The isolating ring structure and the baffling edge structure are arranged at two ends of the tungsten carbide roll ring, stable connection between the tungsten carbide roll ring and an accelerated roller body is guaranteed, the roll ring is prevented from desoldering in high temperature or just being impacted, by means of the isolating structure with small radius, wearing during rolling of the isolating ring structure is prevented, replacement operation of the roll ring is facilitated, and working intensity of workers is reduced.

Description

technical field [0001] The invention relates to the field of processing equipment for steel profiles, in particular to an improved accelerating roller table for assisting steel processing and transmission. Background technique [0002] Ordinary steel is often used in the process of processing and handling. Due to the material of the acceleration roller itself, after a long time of work, the two sides of the acceleration roller are severely worn. Therefore, the common practice is to Add a piece of tungsten carbide roller ring on the edge of the roller table (such as figure 2 As shown), it is welded on the roller table by brazing; when passing steel, the steel bar moves on the tungsten carbide roller ring, because tungsten carbide is relatively wear-resistant, which reduces the frequency of replacing the roller table due to wear and tear of the roller table; but due to the heat conduction of the steel itself , causing the temperature on the accelerating roller table to be to...

Problems solved by technology

[0002] During the processing and handling of ordinary steel, the acceleration roller table is often used. Due to the material of the acceleration roller table itself, after a long time of work, the acceleration roller table There is serious wear on both sides of the roller table, so the common practice is to add a piece of tungsten carbide roller ring (such as Figure 2), welded on the roller table by brazing; when passing steel, the steel bar moves on the tungsten carbide roller ring, because tungsten carbide is more wear-resistant, reducing The frequency of replacing the roller table due to wear and tear of the roller table is reduced; however, due to the heat conduction of the steel itself, the temperature on the accelerating roller table is too high. Desoldering; after desoldering, the steel bars running in the roller table may cause bent steel bars, which brings great troubles to the actual production of the enterprise
