Embodiment Construction

[0010] With reference to accompanying drawing, the present invention comprises a stand and two jacks 5, and stand is made of base plate 1, top plate 3 and two columns 2 that are connected between the base plate and the top plate, on the base plate, between two columns, a The first right angle steel 4, the corner of the first right angle steel is downward, the angle steel edge and the bottom plate form an included angle of 45°, two support plates 6 are arranged symmetrically on the lower part of the top plate, and the center connecting line of the two support plates is located at Directly above the angle line of the first right-angle steel, two jacks are symmetrically fixed on a bar-shaped steel plate 8 equal to the length of the first right-angle steel. The center distance between the two jacks is equal to the center distance between the two support plates. The lower part of the strip-shaped steel plate is fixed with a second right-angle steel 7, and the end edges of the two ri...

Abstract

The invention relates to a steel thin-wall rectangular air duct machining tool which comprises a rack and two jacks. The steel thin-wall rectangular air duct machining tool is characterized in that the rack is composed of a bottom plate, a top plate and two stand columns connected between the bottom plate and the top plate, a first right-angled steel angle is fixed at the portion, between the stand columns, of the bottom plate, the angle part of the first right-angled steel angle faces downwards, the steel angle edge and the bottom plate form a 45-degree included angle, two supporting plates are arranged at the lower portion of the top plate, the two jacks are fixed to a strip-shaped steel plate, a second right-angled steel angle is fixedly arranged at the lower portion of the strip-shaped steel plate, the ends of the two right-angled edges of the second right-angled steel angle are connected with the strip-shaped steel plate at the same time, and the angle part of the second right-angled steel angle faces downwards and can be horizontally placed in the first right-angled steel angle. The steel thin-wall rectangular air duct machining tool has the advantages of being simple in structure, easy and convenient to manufacture, convenient to operate, and capable of completing rectangular air duct right-angle machining on site, not being limited by environment, achieving on-site manufacturing of a steel thin-wall rectangular air duct and decreasing 75% of welding amount of the rectangular air duct.

Description

technical field [0001] The invention relates to a steel thin-wall rectangular air duct processing tool, which belongs to the field of mechanical tooling. Background technique [0002] At present, with people's high standard requirements for living environment and working environment. Some underground parking lots and large industrial plants must adopt central air-conditioning, and the air ducts are generally rectangular air ducts of glass fiber reinforced plastics and thin-walled steel plates. Its good sealing performance affects the construction speed of the air duct, and after factory processing, the air duct is volatile during transportation. Contents of the invention [0003] The purpose of the present invention is to provide a steel thin-wall rectangular air duct processing tool that can quickly and conveniently manufacture steel thin-wall rectangular air ducts on site. [0004] The purpose of the present invention is achieved in the following manner: [0005] The ...
