Servo-actuated die cutting scale apparatus for steel pipe

Abstract

The follow up blank sizing device for a steel tube comprises a symmetrical rolling support block under the upper working bench, parallel rolling bead guide track on the machine base, loop wheel plate on the spherical guide, mold base, rodless cylinder under the loop wheel plate, clamping mechanism at the sides of the mold base at both sides of the steel plate to be machined, broaching device on the top of the mold base, bottom of the support plate connecting to the cutting mechanism, guide post matching with the guide sleeve connecting symmetrically connected on the loop wheel plate face, on which installs symmetrical follow up oil cylinder, end of the sticking out bar of the follow up oil cylinder connecting to the bottom of the support plate respectively. It is reasonable in design, simple in structure, low in cost, small in land occupation and convenient.

Description

technical field [0001] The invention belongs to a steel pipe sizing device, and is particularly suitable for a steel pipe follow-up punching and sizing device for replacing traditional sawing by punching and cutting welded steel pipes. Background technique [0002] At present, there are mainly two types of sizing process tooling in the welded steel pipe industry, one of which is off-line sizing. Its sizing is not set on the production line, but is cut to length on a fixed saw machine outside the production line. , the other is online sizing, which is cut to sizing by flying saws, and their shortcomings are described below: [0003] 1. Slow speed and high cost. The main tool of the online fixed-length flying saw is the saw blade, and the cutting speed is limited by the linear speed and cutting capacity of the saw blade. Therefore, its efficiency has reached the extreme value; from the structural point of view, the first 1. The tool of the flying saw is the saw blade. In ord...

Problems solved by technology

[0003] 1. Slow speed and high cost

The main tool of the online fixed-length flying saw is the saw blade, and the cutting speed is limited by the linear speed and cutting capacity of the saw blade. Therefore, its efficiency has reached the extreme value; from the structural point of view, the first 1. The tool of the flying saw is the saw blade. In order to make the saw blade reach the required linear speed, it is necessary to design a very complicated reducer. expensive

Second, the walking part of the flying saw is completed by gears and racks, because the speed of the saw blade determines the stroke it needs, the slower the speed, the longer the stroke, so the rack of the flying saw is often made very fast long, which naturally increases the manufacturing cost

[0004] 2. Large area

The flying saw is a part of the production line. Because of the long stroke, the length of the entire production line is increased, and the floor space is naturally larger.

[0005] 3. Loud noise

The saw blade produces a lot of noise in the process of cutting metal, which not only affects the physical and mental health of construction workers, but also does not meet environmental protection requirements.
