Auto Taper Standing Seam Machine

Introduction

The cold rolling mill is composed of working mechanism and transmission mechanism.

Cold rolling mill

The working mechanism is composed of stand, roll, roll bearing, roll adjustment mechanism, guide device, roll seat and so on.

(2) The transmission mechanism is composed of gear frame, reducer, roll, coupling shaft, coupling joint, etc.

Introduction of rolling mill:

The gantry type horizontal double active rolling mill consists of two active rolling mills. The installation mode and structure of the two rolling mills are the same. The main drive part adopts the structure form of "motor reducer universal shaft rolling mill". Two rolling mills are horizontal mills. Rollers are installed horizontally. Rollers are installed in gantry archways. Roll rings are sleeved on the main shaft of the roll. Nuts are fixed. Bearing seats are assembled at both ends of the main shaft of the roll. They are installed in the middle of the gantry. Bearing seats and gantry archway frames are installed together. Rollers are fixed horizontally in the middle of the gantry, and the upper and lower rolls are fixed horizontally. The installation method is the same. A reducing mill is to flatten the raw material, extrude the double ribbed steel bar with crescent teeth through two forming mills, and adjust the rolling piece by twisting guide to realize a 90 degree twist of elliptical rolled piece into two rolling mills, rolling the finished steel bar.

Main features:

According to the practical application results of roller press in cement industry, the following main characteristics are summarized: (1) Increasing output: installing roller press in grinding system, its high-pressure load is transferred to the grinded material layer through the diameter of twin rollers, most of the energy is used for the mutual extrusion of materials, and the sound energy produced by material friction. Thermal energy can be transformed into deformation energy of material to make it deform, tear and crush. The potential capacity of grinding equipment can be brought into full play. The output can be increased by 50-100%, the total energy consumption can be reduced by 20-30%, and the production efficiency of the whole system can be improved. (2) Reducing power consumption: grinding materials with roller press. After rolling, not only the particle size of the material decreases greatly, but also the Bond work index decreases significantly, which greatly improves the grinding condition of the subsequent mill and reduces the unit power consumption of the whole grinding system. The total power consumption of the grinding system can be significantly reduced. Compared with the traditional grinding method, it can save 25-50% energy, and has considerable annual energy-saving benefits. (3) Save investment: Compared with pipe mill with the same production capacity, roller mill has simple structure, small volume, light weight, small occupancy of workshop space, which can save investment in civil engineering, and also facilitate the transformation of the original grinding system. In addition, the operation and maintenance of the roller press are very simple. (4) Good working environment: materials in the extrusion roll cover are continuously and steadily extruded and crushed, harmful dust is not easy to diffuse, at the same time, because there is almost no impact, the noise of roller press is much less than that of tube mill. (5) Easy to develop: The traditional tube mill is restricted by processing, transportation, heat treatment and other conditions, and the large-scale tube mill is greatly restricted. The grinding system of roll matching press solves this kind of problem well. Making the grinding system develop to large scale becomes a reality.
