Abstract
The present invention relates to a pipeline thread rolling and processing method and a rolling machine. The rolling machine makes the processed pipeline horizontally clamped in a clamping pipe mechanism driven by an electric machine; before being processed, the rolling machine is provided with a thread rolling mechanism which is internally provided with a roller; the pipeline rotates and enters the thread rolling mechanism; the pipeline and the shaft center are arranged in the middle of three rolling wheels which are arranged according to a center angle of 120 DEG, and the pipeline is rolled and made to be a thread shape. The piping thread rolling machine is composed of a machine seat, an electric motor on the machine seat, a speed reducer, a guide column positioning mechanism and a workpiece clamping mechanism, wherein one side on the machine seat is provided with sliding frames which are arranged on two guide columns of the guide column positioning mechanism, and the sliding frames are provided with the thread rolling mechanism which is internally provided with rolling wheels. Compared with the prior art, the present invention has the characteristics of reasonable structure, smooth threads after being processed and shaped, high precision, good sealing performance, hard leakage, small processing power, etc., and the present invention is favorable for increasing efficiency.
Description
Technical field
What the present invention relates to is a kind of pipeline to be carried out rolling processing with the method for making pipeline thread and the equipment of using this method, belongs to pipe machine processing method and equipment.
Background technology
In the prior art, the method for cutting forming is adopted in the processing of the screw thread of pipeline mostly, and the equipment of using this method has conventional die head threading machine etc.The structure of this die head threading machine is generally by support, motor, decelerator, copying cutting head, guide pillar detent mechanism, compositions such as workpiece clamping mechanism, feed mechanism.The screw thread that the die head threading machine that this mechanism forms cuts out pipeline, because of the material fiber that is cut working position is cut off, original cross section reduces, cause the tensile strength of the nipple of this pipeline to be significantly less than the tensile strength of connected pipe, while it is bad to cut the sealing property of pipeline thread when pipeline connects that processes, often need to seal, increased use cost, be subjected to certain restriction in the use with other auxiliary material.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of method to produce pipeline thread, make it keep the pipeline thread rolling processing method and the rolling mill of original mechanical strength and result of use with roll forming.Pipeline thread rolling processing method of the present invention is: in the flat clamp mechanism that is sandwiched in by driven by motor of processed pipeline, the thread rolling mechanism of dress rolling wheel in processing the place ahead is mounted with, the pipeline rotation also enters in the middle of three rolling wheels of the interior concentric of screw-thread rolling machine structure by 120 degree central angles layouts, is rolled and makes screw-like.
Described rolling wheel is the bar shape that has tapering, be carved with concentric ring recess on it, the axle center of rolling wheel is arranging that with pipeline feeding axle center parallel direction they differ from 1/3rd spiral shell squares in axial front and back position order of placement, and the spiral shell square on the rolling wheel equals to want the spiral shell square of process pipeline.
The described bar shape rolling wheel that has tapering, its tapering is identical with the tapering of the requirements for pipes that will process.
Pipeline thread rolling mill of the present invention, it is by support, motor on the support, reductor, the guide pillar detent mechanism, workpiece clamping mechanism is formed, a side on support, the balladeur train that is installed on two guide pillars of guide pillar detent mechanism is arranged, the thread rolling mechanism of dress rolling wheel in this balladeur train is provided with.
Described thread rolling mechanism includes a plane spiral shell dish, and the turning rolls of rolling wheel respectively is equipped with at least two the inners that this plane spiral shell dish is provided with radial location.
There are three the inners of adjustable square that the turning rolls of rolling wheel respectively is housed by 120 degree central angle radial arrangement on the spiral shell dish of described plane.
Roller shaft is housed in the described turning rolls, is set with the adjustment packing ring of rolling wheel and wheel both sides on the axle, and is shaped on concentric ring recess on the rolling wheel.
The present invention compared with prior art because it changes the machining of pipeline thread into rolling machine-shaping, thereby has rational in infrastructure, screw thread after the machine-shaping is smooth, and precision height, good airproof performance are difficult for leaking, working power reduces, and characteristics such as helps raising the efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: pipeline thread rolling mill of the present invention is to improve to form on the basis of original die head threading machine, as shown in the figure.It is by support 1, the motor on the support, and reductor, the guide pillar detent mechanism, workpiece clamping mechanism is formed, and a side on support 1 has the balladeur train 3 that is installed on two guide pillars 2 of guide pillar detent mechanism, adorns the thread rolling mechanism of rolling wheel 4 in this balladeur train 3 is provided with.Described thread rolling mechanism includes a plane spiral shell dish 5, and it is fixed on the balladeur train 3.There are three the inners of adjustable square that the turning rolls 6 of rolling wheel 4 respectively is housed by 120 degree central angle radial arrangement on the plane spiral shell dish 5; This plane spiral shell dish 5 can be controlled the radially turnover of three turning rolls 6, to adapt to the pipe that varies in size.The inner of described turning rolls 6 is set with the adjustment packing ring 8 of rolling wheel 4 and wheel both sides by a roller shaft 7 on axle, this adjustment packing ring 8 makes three rolling wheels 4 that are sleeved on the roller shaft 7 differ from 1/3rd spiral shell squares in axial front and back position order of placement; Described rolling wheel 4 is a bar shape, it can require to make the column rolling wheel that has certain taper according to the tapering of processed pipeline, be shaped on concentric ring recess on the rolling wheel, its slot pitch equals to want the pitch of process pipeline, the shape of groove is equal to the profile of tooth of wanting process pipeline, when processed pipeline 9 rotates, drive three rolling wheels 4 and rotate and on pipeline, shut out needed thread form.
The pipeline thread rolling method that the present invention adopts in fact is: in the flat clamp mechanism that is sandwiched in by driven by motor of processed pipeline, the thread rolling mechanism of dress rolling wheel in processing the place ahead is mounted with, the pipeline rotation also enters in the middle of three rolling wheels of the interior concentric of screw-thread rolling machine structure by 120 degree central angles layouts, is rolled and makes screw-like.
Described rolling wheel is the cylinder that has tapering, be carved with concentric ring recess on it, the axle center of rolling wheel is arranging that with pipeline feeding axle center parallel direction they differ from 1/3rd spiral shell squares in axial front and back position order of placement, and the spiral shell square on the rolling wheel equals to want the spiral shell square of process pipeline.
The described bar shape rolling wheel that has tapering, its tapering is identical with the tapering of the requirements for pipes that will process.
