Heat-insulating barrel cover cutting-assisting device

Abstract

The invention discloses a heat-insulating barrel cover cutting-assistant device. The heat-insulating barrel cover cutting-assistant device comprises a fixed round base, a compass ruler and a pluralityof compacted magnetic blocks, wherein the fixed round base consists of a hollow cylindrical wall, a cross-shaped support frame and a cross-shaped support base; a round-shaped support base is arrangedat the lower end of the hollow cylindrical wall; the cross-shaped support frame is arranged in the hollow cylindrical wall; the cross-shaped support base is fixedly arranged above the cross-shaped support frame; a plurality of compacted magnetic blocks can be adsorbed on the peripheries of the cross-shaped support base; the compass ruler consists of an axis column and a movable rod; a transversecylindrical straight slot and a longitudinal threaded hole are formed in the axis column; the movable rod passes through the transverse cylindrical straight slot; a screw is arranged in the threaded hole; the bottom of the axis column is provided with a round-shaped base; a groove is formed on the lower-end surface of the round-shaped base; a conical emboss is formed in the groove; a ring-shaped base is arranged at the front end of the movable rod. The heat-insulating barrel cover cutting-assisting device is used for cutting a heat-insulating barrel hole, stainless steel can be flattened better, the compass ruler is provided, so that a complete circle can be cut by an oxygen welding cutting machine for cutting on the stainless steel, the whole operation is more rapid and convenient.

Description

technical field [0001] The invention relates to the field of cutting auxiliary devices, in particular to an auxiliary device for cutting a thermal insulation bucket cover. Background technique [0002] For the existing heat preservation barrel lid, in the prior art, the mark of the mouth of the barrel is drawn on the circular stainless steel, and then manually cut along the mark with an oxygen welding cutting machine, the cut is often uneven or even incomplete The round shape is very unfavorable to the later installation, so now we need one that can fix the stainless steel and cut out the round mouth quickly and completely. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an auxiliary device for cutting the heat preservation barrel lid, so as to solve the above-mentioned multiple defects caused by the prior art. [0004] In order to achieve the above object, the present invention provides the following technical ...
