Abstract
The utility model relates to a threaded pipe rolling mill, in particular to a thread rolling device arranged on bed surface of a machine tool. The threads rolling device is a round-shaped frame; three idler wheel frames whose radial positions are adjustable are radially and evenly laid out on the circumference of the round-shaped frame; idler wheels whose angle is adjustable are arranged on the idler wheel frame, wherein one idler wheel has two supporting wheels. The utility model has the advantages of adjustable threaded pipe rolling diameter and thread pitch. While rolling the threads utilizing the utility model, the shortcomings usually generated during the course of working piece extruding can be avoided, with nice product finish.
Description
The utility model belongs to the screwed pipe processing machine, particularly a kind of screwed pipe rolling press.
Screwed pipe has the raising heat transfer coefficient at present, increases the characteristics such as consumption of heat exchange area and minimizing steel, more and more is widely used in the boiler manufacturing.At present, how the processing of screwed pipe is made by a kind of special equipment roll extrusion.Generally by actuating unit, rolling screw-threads device (rolling wheel, bogie wheel) and leading screw walking mechanism, compositions such as lathe bed.During the machining screw pipe, workpiece to be machined one end is clamped on the drive chuck of actuating unit, and the other end passes the rolling screw-threads device, starts actuating unit, do the length feed motion by leading screw walking mechanism drive actuating unit and workpiece to be machined, until being rolled into whole reaches.Screwed pipe roll extrusion diameter and roll extrusion pitch can not regulated at will.Its long processing time.
The purpose of this utility model provides a kind of screwed pipe rolling press, overcomes the shortcoming and defect of prior art.
The purpose of this utility model is achieved in that
A kind of screwed pipe rolling press, it is characterized by: be mounted in the rolling screw-threads device on the lathe bed surface, the rolling screw-threads device is a circular frame, the circumference radial equipartition of circular frame is installed three turning rolls of adjustable pitch diameter to the position, the roller of adjustable-angle is installed on the turning rolls, and one of them roller has two bogie wheels.
The circumference radial equipartition guide rail of circular frame is installed three turning rolls of adjustable pitch diameter to the position feeding on it, turning rolls has the roller of axis hole adjustable-angle of mounting strap axle bed and rotating shaft on it, and one of them roller has two bogie wheels.
The utility model has the advantages that:
1) length feed motion is the workpiece rotation and forces roller to roll relatively by frictional force, makes rolling wheel drive the rolling supporting plate, moves as length feed along bed ways.
2) three rollers of rolling screw-threads device (screw thread pressure head) circumference radial equipartition, three rollers can be adjusted screwed pipe roll extrusion diameter by screw mechanism (leading screw).
3) three rollers of rolling screw-threads device (screw thread pressure head) circumference radial equipartition, three rollers rotate a lead angle in the same way relative to workpiece, can adjust screwed pipe roll extrusion pitch.
4) during this device rolling screw-threads, the defective that has easily produced when having avoided workpiece to be extruded, the finished surface quality is good.
Below in conjunction with description of drawings embodiment:
Fig. 1 is a screwed pipe rolling press structural representation
Fig. 2 is a screwed pipe rolling press profile
Fig. 3 is a screwed pipe rolling press roller profile
Fig. 4 is a screwed pipe rolling press roller sectional side view
A kind of screwed pipe rolling press, be mounted in the rolling screw-threads device on the lathe bed surface, the rolling screw-threads device is a circular frame 1, the circumference radial equipartition of circular frame is installed three turning rolls 2,3,4 of adjustable pitch diameter to the position, the roller 5 of adjustable-angle is installed on the turning rolls, and one of them roller has two bogie wheels 6,7.
The circumference radial equipartition guide rail 8 of circular frame is installed three turning rolls of adjustable pitch diameter to the position feeding on it, turning rolls has the roller of axis hole 9 adjustable-angle of mounting strap axle bed 10 and rotating shaft 11 on it, and one of them roller has two bogie wheels.
Structure and operation principle
This screwed pipe rolling press reaches unit head by motor, reductor through driving member (gear or sprocket wheel), and scroll chuck is housed on the unit head, drives workpiece and rotates; The workpiece other end passes rolling screw-threads device (screw thread pressure head), three rollers of rolling screw-threads device circumference radial equipartition, two bogie wheels of one of them rolling wheel, length feed motion and radially the feed campaign realize by rolling wheel.
Before the work, three rollers are by screw mechanism (leading screw), make its radially near and draw close workpiece, three rollers rotate a lead angle in the same way relative to workpiece simultaneously, rotation direction is consistent with the hand of spiral of workpiece, subsequently rolling wheel radially feed put in place.During work, workpiece rotates and forces roller to roll relatively by frictional force, and under the effect of axial force, makes rolling wheel drive the rolling supporting plate, moves as length feed along bed ways.In motion process, the annular convex shoulder on the rolling wheel contacts with workpiece, and workpiece is extruded, and produces distortion, thereby forms screw thread.
Claims (2)
1, a kind of screwed pipe rolling press, it is characterized by: be mounted in the rolling screw-threads device on the lathe bed surface, the rolling screw-threads device is a circular frame, the circumference radial equipartition of circular frame is installed three turning rolls of adjustable pitch diameter to the position, the roller of adjustable-angle is installed on the turning rolls, and one of them roller has two bogie wheels.
2, screwed pipe rolling press according to claim 1, it is characterized by: the circumference radial equipartition guide rail of circular frame, three turning rolls of adjustable pitch diameter to the position feeding are installed on it, turning rolls has the roller of axis hole adjustable-angle of mounting strap axle bed and rotating shaft on it, and one of them roller has two bogie wheels.
