Modified structure of welding pipe squeezing roller seat

Abstract

The invention belongs to the field of machining of steel pipes, and particularly relates to a modified structure of a welding pipe squeezing roller seat. The modified structure of the welding pipe squeezing roller seat comprises a pressing wheel base plate, a screw rod arranged on the pressing wheel base plate, a sliding block which is arranged on the screw rod in a sleeved mode and driven by the screw rod, a squeezing mechanism arranged on the sliding block, and limiting guide wall plates which are arranged on the pressing wheel base plate and located at two sides of the sliding block. The sliding block comprises a connecting section located at the upper portion and a guide transmission section located at the lower portion, wherein the parts, located at two sides of the connecting section, of the top of the guide transmission section are limiting shoulders, a pressing plate is arranged at the top of each limiting guide wall plate, a correcting strip is arranged between one limiting shoulder and one pressing plate, and a plurality of correcting components which abut against each correcting strip to correct the sliding block indirectly is arranged at the outer side of each correcting strip. The correcting strips are arranged on the convex shoulders of the sliding block to timely correct the sliding block when the sliding block deviates, the rounding degree of steel pipes is guaranteed, the sliding block can be corrected by simple bolt regulation from the outer side and is corrected conveniently, and equipment is not damaged easily.

Description

technical field [0001] The invention belongs to the field of steel pipe processing, and in particular relates to an improved structure of a welded pipe extrusion roller seat. Background technique [0002] The processing method of making a steel pipe from a steel plate, that is, a welded pipe, is to gradually bend the steel plate into a circle through an extrusion device. Extrusion forming, the extrusion mechanism is connected with the screw rod through the slider, and the slider is set in the guide groove composed of the bottom plate and two wall plates. During the processing, due to the small gap between the slider and the wall plate, after long-term operation, The slider is twisted or deflected, and is constantly rubbing against the wall plate. Both the slider and the wall plate will be damaged to a certain extent, resulting in insufficient roundness of the extruded steel pipe, and the screw rod will be twisted when the slider deflects, and The frictional force between th...

[0002] The processing method of making a steel pipe from a steel plate, that is, a welded pipe, is to gradually bend the steel plate into a circle through an extrusion device. Extrusion forming, the extrusion mechanism is connected with the screw rod through the slider, and the slider is set in the guide groove composed of the bottom plate and two wall plates. During the processing, due to the small gap between the slider and the wall plate, after long-term operation, The slider is twisted or deflected, and is constantly rubbing against the wall plate. Both the slider and the wall plate will be damaged to a certain extent, resulting in insufficient roundness of the extruded steel pipe, and the screw rod will be twisted when the slider deflects, and The friction between the slider and the wall board is also increased, and it needs to be disassembled as a whole for correction or replacement of parts. The whole set of equipment is easy to be damaged, and maintenance is troublesome, which increases production costs and reduces work efficiency.
