A profile cutting device

Abstract

The invention provides a section bar cut-off device, and belongs to the technical field of machining. The section bar cut-off device comprises a cut-off mechanism and a guide mechanism. A guide plate of the guide mechanism is installed on a bearing frame through locking screws. Section bar guide holes are formed in the guide plate. Guide grooves corresponding to the section bar guide holes in the guide plate are formed in a machine frame. A tool rest rod of the cut-off mechanism is arranged on slide guide sleeves in a slidable manner. A cut-off tool is installed at the lower end of the tool rest rod. Tool guide frames are arranged on the two sides of the cut-off tool. One end of a lever is hinged to a lever supporting lug. A U-shaped groove is formed in the middle end of the lever. A pin shaft is arranged on the tool rest rod and inserted in the U-shaped groove in the middle end of the lever. One end of a drive cylinder is hinged to a cylinder support, and the other end of the drive cylinder penetrates an anti-collision groove of a fixed support and is hinged to the other end of the lever. By means of the section bar cut-off device, section bars can be rapidly cut off, the surfaces of the section bars which are cut off are smooth, and the section bar cut-off device is suitable for the section bars of various shapes and types, reasonable in structure and high in applicability.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a profile cutting device. Background technique [0002] Section bar is an object with a certain geometric shape made of iron or steel and materials with certain strength and toughness (such as plastic, aluminum, glass fiber, etc.) through rolling, extrusion, casting and other processes. I-beams, channel steels, and angle steels are widely used in industrial buildings and metal structures, such as factories, bridges, ships, agricultural machinery and vehicle manufacturing, transmission towers, and transportation machinery. They are often used together. Flat steel is mainly used for bridges, house frames, fences, power transmission, ships, vehicles, etc. Round steel and square steel are used for various mechanical parts, agricultural machinery accessories, tools, etc. Profiles generally need to be cut to a certain length before use to adapt to subsequent processing ...

AI Technical Summary

Problems solved by technology

The above two methods are complex in structure, time-consuming and laborious to operate, and the poor fixing effect of the profile during the cutting process causes large vibration of the profile, which will cause uneven cutting surface and many burrs, which will affect the use of the profile, and these profile cutting devices are often only applicable Applicable to one type of profile, or only applicable to one size of profile, poor applicability
