Clamping mechanism and portable machining device for machining fire-fighting air duct on site

Abstract

The invention discloses a clamping mechanism and a portable machining device for machining a fire-fighting air duct on site. The portable machining device is relatively small in size and suitable forcarrying. In addition, mechanical operation is adopted, so that the efficiency can be greatly improved, and the machining quality can be guaranteed. The portable machining device comprises a machiningplatform and a knocking module, wherein the machining platform is used for clamping, supporting and rotating a fire-fighting air duct, so that hemming and flange mounting of the fire-fighting air duct are facilitated; and the knocking module is used for knocking a first hemming part and a second hemming part, needing hemming, of the fire-fighting air duct through a knocking hammer, so that hemming and flange mounting of the fire-fighting air duct are achieved. The portable machining device is simple in structure, small in size and very suitable for carrying, and the problem that no fire-fighting air duct equipment is machined on site at present is solved. In addition, semi-automation can be achieved in the whole process, and the machining efficiency is at least 5 times or above higher than the manual efficiency. Meanwhile, mechanical and standardized machining is achieved, the stability of product quality can be effectively guaranteed, and quality control is better facilitated.

Description

technical field [0001] The invention relates to the processing technology of fire-fighting air ducts, in particular to a portable processing device for on-site processing of fire-fighting air ducts. Background technique [0002] The current processing method of the fire smoke exhaust duct (referred to as the fire duct in this case) is roughly as follows: [0003] 1. Two bending plates 100 are used to buckle each other to form a prototype; [0004] 2. Beat the seam portion 110 of the bent plate 100 so that the seam portion 110 bends toward the clamping portion 120 to form a first curling portion 130, and the first curling portion 130 and the seam portion 110 clamp the clamping portion 120, So as to realize the sewing of the whole fire blower; [0005] 3. Connect the flange 200, then drill holes on the flange and the fire-fighting air duct, and then tighten the screws to realize the flange 200 and install the flange on the fire-fighting air duct. [0006] This method mainly...

AI Technical Summary

Problems solved by technology

[0007] 1. Most of the fire-fighting ducts are made on-site, and the seams are hand-beaten, which is extremely inefficient, and the quality varies, making quality control very difficult

[0008] 2. Although the inventor has mentioned in the previous application (application number 2020105454699) that the flange can be fixed by crimping the flange, but it still involves manual beating on the crimping, and the problem still comes back to manual operation. The quality is even more uneven

[0009] At present, the relevant sewing edge and processing equipment set by the inventor are too large to be transported to the site for processing, but many engineering quantities are small and require on-site measurement and installation. Related equipment is still required for on-site processing. Problem, the inventor has designed a portable processing device for on-site processing of fire blowers, which is relatively small in size and suitable for handling, and adopts mechanized operation, which can greatly improve efficiency and ensure processing quality
