Self Aligning Turning Rolls

Self aligned turning rolls are mainly composed of: base, driving rollers (aka driver), idle rollers (aka idler), driving mechanism, and control system, which is ready to use once delivered, with no installation required. Self aligned turning rolls adopt the friction mechanisms between the roller and the workpiece to lead rotation. The distance between rollers can adapt automatically based on different workpiece diameters, which is different from the mechanism of adjustable turning rolls.

Application

Description

The driver and idler frames are made of steel plate structure brackets; main accessories like bearing shafts are made of high-quality steel. They are all quenched and tempered before being processed. Such assembled Self aligned turning rolls can realize the strong rigidity, good performance and high loading capacity.

 

Each of driver and idler unit has four wheels on the set of Self aligned turning rolls, and four wheels on the driver rotate synchronously. The roller adopts an integral roller structure. PU covered wheels are made of high-quality polyurethane, which has high load-bearing capacity and wearing resistance. Such design avoids aging and degumming, with advantages of high performance and low replacing and maintenance costs.

Swing arm on the Self aligned turning rolls automatically adapts to the requirements of different diameter workpieces. The rotating shaft of the clamp frame on the Self aligned turning rolls assembly has strong rigidity. When the workpiece is placed on the Self aligned turning rolls, the gap between the rotating shaft and the shaft hole can ensure that the clamp frame opens at a suitable angle to adapt the diameter request of workpieces. An oil groove is designed and made on the rotary shaft, which can be filled with grease frequently to ensure good lubrication.

The self aligned turning rolls is widely used for assembly and welding of heavy cylindrical workpieces such as pipelines, pressure vessels, industry boilers, autocalves, and transport tanks, etc. Industry boilers are used to produce hot water or steams, which is made by welding thick steel plates. Autoclaves are commonly used for the sterilization of glass and metal containers, generally in the food industry, with high hermetic standard in production. So assisted by welding manipulator, self aligned turning rolls can be used to weld the inner and outer longitudinal seams or the inner and outer circumferential seams of the tanks to ensure meeting hermetic condition and standards of food industry.

Application Field

  • Petrochemical Industry

  • Environmental Protection

  • Steel Structure

  • Power Tower

  • The petrochemical industry plays a crucial role in enhancing the growth and economy of the world. Additionally, petroleum products produced in offshore and onshore exploration, refining, and oil production have also increased, resulting in increasingly complex waste production. This industry is a vital source of inorganic toxic and organic materials. 

    For the run of the industries present worldwide the top-quality equipment is mandatory. Several types of machinery producing industries are present worldwide but choosing the right one is a little confusing. Don't worry; we are here for your help. Giving the right solutions and shipments to your industry is our duty.

    Here are 3 must haves of welding automations for the fabrication process in the petrochemical industry:

    1) Conventional welding rotators

    2) fit up welding rotators

    3) welding manipulator.

  • Wind towers have saved 30% of nonrenewable energy while producing electricity. Today, there are hundreds of wind farms and sea areas are having thousands of wind towers. They hold the generator or dynamo blades, which are tones of weight. These wind power infrastructures are standing strong due to the use of welding rotators, welding manipulator, and welding positioners to be a tank assembly line. Experts in technology and engineering make them.

  • Steel structure has become an indispensable material type used in modern construction industry. Due to the feature of environmental friendly, it has been widely used in construction, such as steel structure factory building, ordinary steel construction building, boiler, pressure vessel, shipbuilding, electric power, petrochemical, petroleum engineering machinery, bridge construction, metallurgical machinery industry, wind power and power tower etc. The bird's Nest building in Beijing, China, is a classic masterpiece of steel structure architecture.

    The h-beam steel production line made by Fengwei Machinery is a highly automated steel structure production line which composes of CNC flame cutting machine, h beam assembly machine, h beam welding machine, and h beam straightening machine. It greatly reduces labor intensity and production costs, improves production efficiency.

     

  • The application of automatic welding and cutting equipment in the manufacturing process of steel tube tower can thoroughly optimize and upgrade the original production process. The traditional production mode adopts the operation of lifting semi-finished products, which requires a special person to be responsible for the lifting and operation of semi-finished products. It has high requirements on the environment and working space, which not only requires a lot of manpower and material input, but also has high labor intensity with low production efficiency. Different from the traditional production mode, the automatic cutting equipment integrates online monitoring, automatic upload and offload raw materials and other automatic functions, can reduce the workload of workers and work intensity, thus greatly improving the production efficiency. The production lines of cutting, pairing and welding can cover each area of the workshop, which can be operated as a whole or independently in each area.
