Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe production, in particular to a stainless steel pipe continuous cutting device. Background Art

[0002] Stainless steel is a special alloy mainly composed of iron, carbon and at least 10.5% chromium. Chromium reacts with oxygen to form a protective passivation layer, which makes stainless steel have excellent corrosion resistance. In addition, stainless steel has good processability and beautiful appearance, so it is widely used in many fields. Stainless steel pipes can be cut in many ways, including mechanical cutting, laser cutting and water jet cutting. Each cutting method has its own characteristics and applicable scenarios. Mechanical cutting is a common cutting method and is suitable for stainless steel pipes of various sizes. This method is usually cut with tools such as saws or lathes. When using a saw for cutting, you need to pay attention to the selection of the saw and the sawing speed. Generally speaking, the more saws there are, the higher the cutting accuracy, but the cutting speed will be relatively slow. At the same time, the sawing force also needs to be moderate, and excessive force may cause deformation or damage;

[0003] At present, the prior art CN 218694321 U discloses a continuous cutting device for stainless steel bar production and processing, including a base, a cutting machine frame is installed at one end of the top of the base, and a first electric push rod is installed at the top of the cutting machine frame, and an electric cutting knife is installed at the output end of the first electric push rod. The utility model starts the third electric push rod to drive the material block to move outward to separate it from the positioning seat after the current cutting is completed. At this time, the stainless steel bar body after cutting falls into the material trough, and realizes a multi-stage deceleration function under the mutual cooperation of the first buffer plate, the second buffer plate, the first deceleration protrusion and the second deceleration protrusion to slow down its falling speed and avoid collision damage to the stainless steel bar body during the rolling process. The stainless steel bar body after unloading falls into the material receiving box for collection, so as to reduce the time and labor of manual picking, improve work efficiency, and facilitate the implementation of the device connection cutting operation.

[0004] The above prior art also has the following problems:

[0005] Thin-walled steel pipes are easily deformed by free-fall impacts. The free-fall collision will cause the ends and body of the steel pipe to deform. In addition, the steel pipes that fall into the collection box are arranged in a chaotic manner, making them inconvenient to take and organize, and there are also safety hazards in the working environment.

[0006] The cutting length is uneven. The essence of steel pipe feeding is that the radial force and friction of the clamping block do work on the steel pipe, causing the steel pipe to move in the axial direction. However, due to the influence of the friction coefficient and the dead weight of the steel pipe, the steel pipe and the feed will slide relative to each other during feeding, and the positioning function of the threaded rod and the threaded sleeve under the feeding seat will lose its function. The feeding length of the steel pipe cannot ensure consistency and accuracy.
