Description

technical field [0001] The invention belongs to the technical field of combined tooling for processing cylinders, and in particular relates to a large-diameter, ultra-long rotary variable-diameter cylinder, a special tooling used for machining outer circles and end faces. Background technique [0002] The mixing equipment is one of the main equipments of the sintering plant, which is installed between the batching equipment and the sintering machine to provide the sintering machine with uniformly mixed raw materials suitable for sintering. The cylinder mixer is mainly composed of cylinder device, transmission device, supporting wheel, retaining wheel device, sprinkler device, head and tail chute and bracket, etc. The working process is: the belt conveyor directly or through the feeding funnel continuously inputs the mixed material In the cylinder, with the rotation of the cylinder, the mixture in the cylinder is continuously brought to a certain height, then thrown down and ...

AI Technical Summary

Problems solved by technology

[0007] With the large-scale development of the mixer, the specifications of the cylinder gradually increase. Now the cylinder is welded by two cylinder joints, and the specification of the cylinder increases to: Ф (2000-3000) mm × (5000-8000) mm, which is To ensure that the cutting force generated during the processing of the cylinder flange and the end face causes the tolerance of the cylinder deformation to be out of tolerance, the processing technology design scheme adopted: truck + front top plate + rear top plate; the front and rear top plates are based on equipment and Cylinder processing requires self-designed jigs. This kind of processing technology and jig guarantee realizes the processing of the end face and outer circle of the cylinder, but due to the increase in the size of the cylinder and the increase in its own weight, the cylinder is affected by the machine tool during the outer circle processing. Due to the influence of the spindle speed and the cutting force of the tool, the deformation of the cylinder may occur from time to time. At the same time, due to the poor processing stability, jumping occurs during processing, which affects the matching accuracy and the overall assembly and transmission stability of the cylinder.

[0008] In recent years, with the heavy-duty, large-scale and international needs of metallurgical equipment, the specifications of the existing mixers have undergone tremendous changes, and the demand has reached: Ф (3600-6500) mm × (8000-20000) mm, and the cylinder is mostly composed of ( 3-5) It is assembled and welded by several cylinder sections, and the weight reaches 10t. The existing equipment with a weight of eight meters and a truck can not meet the processing needs of the cylinder.

However, only 20-meter CNC floor lathes can be used. In order to ensure high-quality and high-efficiency production, there is a need for a variable-diameter cylinder processing combination tooling that can be used with 20-meter CNC floor lathes.
