Abstract
A push-pull open-close thread rolling wheel type screw thread roll machine working head, the outer shape of the front and back slide seat disk taking on circular disc shaped the is fixedly connected through a connecting sleeve, at least three slotted holes distributed on the circumference are respectively equipped in the radial direction, a rectangular concave groove is equipped on the inner side of the slotted hole and mutually matched with a rectangular convex shoulder on the outer side of the sliding seat. The position of the thread rolling wheel can be fixed by the sliding seat, a convex plate or an inclined plane is equipped on the top section of the sliding seat, the geometrical shape of the cross section opposite to the geometrical cross section of the concave groove or the inclined plane in a half sliding bush, the axle direction moves the half sliding bush, when the convex plate or the inclined plane on the top section of the sliding seat enters into the concave groove in the half sliding bush or closely leans on the inclined plane under the function of the spring force, the thread rolling wheel spreads out and completely detaches from workpiece, the thread rolling wheel is not restrained by the workpiece screw thread, thereby the workpiece can be rapidly exited, to make the production efficiency to improve. Because the thread rolling wheel does not touch with the workpiece, when exiting the workpiece, thereby the service life of the thread rolling wheel can be improved. In reverse, when the sliding seat is pressed down, the thread rolling wheel collects and enters into a rolling.
Description
One, technical field
The utility model relates to the wheeled screw-thread rolling machine working head of a kind of push-and-pull folding rolled thread, and it belongs to the machining equipment technical field.
Two, background technology
Squeezing thread is to make metal generation plastic deformation and form screw thread with the method for pushing, it is one of method of ELEMENTARY INTRODUCTION TO NON, the method of rolling machining screw can improve intensity, case hardness and the wearability of screw thread, and has the utilization rate of higher production efficiency and material.Obtained on the screw thread of anchor pole afterbody in reinforcing steel bar machinery connecting thread in construction and the mining tunnel supporting using widely.The cylindrical die roll of the thread rolling process equipment that present work piece is fixing does not mostly possess the function of folding, generally machining the back at thread rolling relies on the counter-rotating of motor to make cylindrical die roll withdraw from workpiece along the screw thread that processes, this method that withdraws from workpiece has following weak point: 1, post-set time long, production efficiency is low.When 2, withdrawing from cylindrical die roll there are to a certain degree wearing and tearing.3, the reduction in service life that makes motor and electrical equipment is switched in the frequent rotating of motor.
Three, summary of the invention
For solving the problem that the fixing thread rolling equipment cylindrical die roll of existing work piece can not folding, the utility model provides a kind of push-and-pull folding rolled thread wheeled screw-thread rolling machine working head.This working head can be after thread rolling machines, and cylindrical die roll radially opens along workpiece (main shaft), makes cylindrical die roll break away from workpiece fully, and cylindrical die roll is not subjected to the constraint of institute's workpiece processing thread, can withdraw from workpiece rapidly.
