Technical Field

The invention relates to the field of pipe machining, in particular to a welding seam leveling machine.

Background

Stainless steel pipes, called welded pipes for short, are made of steel strips by welding after being curled and formed by a unit and a die. The stainless steel pipe needs to enter a welding seam processing procedure and a shaping procedure after being welded, the welding seam position is smooth through the welding seam processing procedure, and the stainless steel welded pipe is regular in structure through the shaping procedure.

At least two driving sources are needed for the welding seam leveling machine on the market at present to provide driving force for the welding seam leveling machine, the driving sources are generally driven by a hydraulic system or an oil cylinder, oil in the oil cylinder is easy to leak when the oil cylinder is used, and operators need to fill oil into the oil cylinder at intervals. When the hydraulic system is used, the problems of high power consumption, high failure rate, high use cost, complex operation and the like exist. Therefore, the use of multiple driving sources doubles the probability of the above problems, which greatly increases the failure rate of the equipment and the operation cost of the enterprise.

Disclosure of Invention

The invention aims to provide a welding seam leveling machine which is low in failure rate, so that the processing efficiency of equipment is greatly improved, and the operation cost of enterprises is reduced.

The technical purpose of the invention is realized by the following technical scheme: the utility model provides a welding seam evener, includes the frame, be equipped with the lower part guiding groove in the frame, it is provided with the transfer roller along horizontal direction reciprocating motion to slide in the guiding groove of lower part, be equipped with the upper portion guiding groove that is located lower part guiding groove top in the frame, it is provided with the compression roller to slide in the guiding groove of upper portion, form the passageway that supplies tubular product to pass through between compression roller and the transfer roller, be equipped with in the frame and drive the compression roller and move and make the compression roller be located the first actuating mechanism directly over the transfer roller all the time with the transfer roller, the motion stroke of compression roller is used for the extrusion stroke section of extrusion tubular product and with the trip section of breaking away of tubular product separation including the cooperation transfer roller, the compression roller circulates between extrusion stroke section and the trip section of breaking away.

Through adopting above-mentioned technical scheme, first actuating mechanism drive transfer roller moves in lower guiding groove, drive pinch roller moves in upper portion guiding groove to the compression roller that makes upper portion guiding groove internal motion is located directly over the transfer roller that moves in lower guiding groove all the time. Tubular product passes through the passageway and realizes transmitting on the transfer roller, and the transfer roller is along horizontal direction reciprocating motion under the guide of lower part guiding groove, when the compression roller was at extrusion stroke section internal motion, the compression roller cooperation transfer roller was extrudeed the atress and was driven the axial motion of compression roller and transfer roller along tubular product under the extrusion state in step under the drive of a actuating mechanism between the two to the tubular product welding seam of transmission, comes to extrude the flattening to the welding seam on the tubular product, accomplishes the processing to the tubular product welding seam.

After the leveling machine finishes processing the welding seam of the section of the pipe, the compression roller enters the disengagement stroke section from the extrusion stroke section, so that the compression roller does not contact the position of the processed pipe to provide space for normal transmission of the pipe, and the position of the compression roller is changed by matching with the driving of the first driving mechanism. After the position of the welded seam of the pipe processed at the section is transmitted through the leveling machine, the compression roller enters the extrusion stroke section from the separation stroke section under the driving of the first driving mechanism, and extrudes the welded seam to be processed at the next section of the pipe, so that the welded seam is leveled and processed in a reciprocating manner. This kind of setting mode combines ingenious transmission relation to realize two ascending direction movements of vertical and horizontal direction of compression roller through a drive mechanism, has reduced the use amount of driving source, has reduced the emergence of fault rate to promote the machining efficiency of equipment greatly, reduced the operation cost of enterprise.

Further setting the following steps: throw off the motion direction of stroke section along the compression roller and include consecutive first linkage segment, second in proper order and throw off section and third linkage segment, first linkage segment links to each other with the both ends of extrusion stroke section respectively with the third linkage segment, first linkage segment is thrown off section one side towards the second along vertical upward direction gradually and is the slope setting and be used for guiding the compression roller upward movement, the third linkage segment forms a guide section that is used for guiding the compression roller to get into the extrusion stroke section with the junction of extrusion stroke section.

Through adopting above-mentioned technical scheme, the compression roller that is located the extrusion stroke section gets into the second through first linkage segment and takes off the section, reduces the resistance to compression roller upward movement constitution through setting first linkage segment to the mode that the slope set up, makes the upward movement that the compression roller can be more smooth and easy under drive mechanism's drive. The compression roller that gets into the second and take off the section gets into the extrusion stroke section through third linkage segment and guide section, plays the guide effect through the direction of motion of guide section to the compression roller, makes the compression roller can be more smooth and easy gets into the extrusion stroke section to ensure the steady operation of compression roller.

Further setting the following steps: first actuating mechanism sets up the balladeur train in the frame including sliding, forms in the drive waist shape hole of balladeur train and drive balladeur train reciprocating motion's driving piece, the direction of motion of balladeur train and the direction of motion of transfer roller parallel, the vertical setting in drive waist shape hole, transfer roller and compression roller all be located drive waist shape downthehole and all sliding fit with it.

Through adopting above-mentioned technical scheme, driving piece drive balladeur train drives transfer roller and compression roller synchronous motion through drive waist shape hole, forms the drive power and the formation that supplies its motion space along vertical direction motion along its direction of motion to transfer roller and compression roller through drive waist shape hole to realize transfer roller and compression roller and move respectively in lower part guiding groove and upper portion guiding groove.
