Problems solved by technology

[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

Example Embodiment

[0027] Example one:

[0028] An improved structure for a welded pipe squeeze roller base, comprising a pressure wheel base plate 1, a screw rod 2 arranged on the pressure wheel base plate 1, a sliding block 3 sleeved on the screw rod 2 and driven by the screw rod 2, and The extrusion mechanism on the slider 3 and the limit guide wall plates 4 on the base plate 1 of the pressing wheel and located on both sides of the slider. The slider 3 includes a connecting section 31 at the upper part and a guide transmission section 32 at the lower part, The top of the guide transmission section 32 is located on both sides of the connecting section 31 as limit shoulders 33. The top of the limit guide wall plate 4 is provided with a pressure plate 41. A correction strip 5 is provided between the limit shoulder 33 and the pressure plate 41. A number of correcting components 51 pressed against the correcting strip 5 to indirectly correct the slider 3.

[0029] The bottom surface of the correcting ...

Example Embodiment

[0031] Embodiment two:

[0032] The difference from the above embodiment is that the included angle between the correcting surface and the horizontal plane is 30 degrees, and two bolts are provided along the correcting groove.

Example Embodiment

[0033] Embodiment three:

[0034] The difference from the foregoing embodiment is that the angle between the correcting surface and the horizontal plane is 60 degrees, and 5 bolts are arranged along the correcting groove.

[0035] The number of bolts can be selected according to the length and size of the slider.

[0036] When the slider is twisted or deflected in the horizontal or gravitational direction, adjust the correcting component at the corresponding position, namely the bolt, so that the correcting bar applies more force to the twisted part of the slider or reduces the applied force, and the slider Correction does not require disassembly or replacement of components, and can be corrected from time to time, which not only ensures the normal sliding of the slider but also ensures that the slider does not deflect, thereby ensuring the high roundness of the steel pipe extruded by the extrusion mechanism.

[0037] By setting a correction strip on the limit shoulder of the slider, ...

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...
