Abstract

The invention relates to a digital-control cold-extrusion reducing and thread forming machine, belonging to the field of novel special thread machinery. The invention has the main technology that theforming machine is provided with a special hydraulic reducing mechanism and a special three-shaft output planet gear transformation ratio device; the power of a hydraulic station drives the special hydraulic reducing mechanism to act; one end of a workpiece is drawn down to a required dimension in one way; the power of an electromotor is transmitted by a belt and a stepless speed-change hard gearsurface reducer to drive the three-shaft output planet gear transformation ratio device and then is transferred to a rolled thread wheel by a universal joint so that the rolled thread wheel can extrude rolled threads around the external diameter of the rolled thread and automatically rotates, and the workpiece is made into a thread under the working condition that the workpiece is fixed and does not rotate. The invention has the advantages that reducing and rolled extrusion are completed at one time, an ultra-long workpiece and a workpiece with one heterogenic end can be conveniently processed; the complete machine realizes digital control and automatic station alternation, thereby increasing the efficiency by more than 3 times. The invention has single-person operation, time and labour saving, safety, reliability, novel design, reasonable structure, convenient maintenance and wide use.

Description

Digital-control cold extrusion reducing and thread forming machine

One. technical field:

The invention belongs to new exclusive screw thread mechanical field.

Two. background technology:

Along with the sustained and rapid development of Chinese national economy, all trades and professions are fields such as mine, tunnel, subway, skyscraper especially, and double thread moulding special-purpose machinery has proposed more and more higher requirement.Traditional thread chasing machine and die head threading machine all require cutting tool to do axially-movable, long processing time, and efficient is low; And all being workpiece and cylindrical die roll, together rotates by existing screw-rolling machine, thereby do not process the special-shaped workpiece of super long workpiece and an end, as mine anchor pole, tunnel anchor pole, subway anchor pole, foundation bolt etc., produce very dangerous, labor strength is big, working condition is poor, has to adopt the method spreading of welding under many situations, and intensity does not satisfy requirement; And undergauge and rolled thread are finished respectively by two equipment, and its efficient is had a greatly reduced quality.

Three. summary of the invention:

Purpose of the present invention be exactly the special-shaped screw thread of design a kind of processing super long easily and an end, workpiece fixedly cylindrical die roll by the helical pitch calibration, once finish undergauge and rolled thread, digital-control cold extrusion reducing and thread forming machine safely and efficiently.

The technical scheme that technical solution problem of the present invention is adopted is: dedicated hydraulic undergauge mechanism and special-purpose three output planetary gear no-load voltage ratio devices are installed on the make-up machine, the undergauge and the rolled thread of workpiece are once finished, the power drive dedicated hydraulic undergauge mechanism action of Hydraulic Station, with the unidirectional undergauge of workpiece one end to requiring size, fall into the rolled thread hydraulic tongs through jacking displacement frame conversion station and clamp, change the rolled thread operation over to; Drive special-purpose three output planetary gear no-load voltage ratio devices by the driving gear that is installed on reducer output shaft, pass to cylindrical die roll around extruding rolled thread of workpiece external diameter and initiatively rotation by universal joint again, under the operating mode that workpiece maintains static, make screw thread; Switch board and computer touch screen is installed on the frame, and complete machine adopts digital control and automatic conversion station.The invention has the beneficial effects as follows: both overcome traditional cutted thread and mantle fiber long processing time, inefficient drawback, this has become the rolled thread technology that existing screw-rolling machine workpiece must together rotate with cylindrical die roll again, the workpiece such as the anchor pole of a processing super long and an end abnormal shape easily, foundation bolt etc., and undergauge and rolled thread extruding is once finished, complete machine is realized digital control and automatic conversion station, efficient is improved more than three times, the one man operation, time saving and energy saving, safe and reliable, novel in design, rational in infrastructure, keep in repair easy, of many uses.

Five. the specific embodiment:

Describe details of the present invention and working condition in detail in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4.Dedicated hydraulic undergauge mechanism and special-purpose three output planetary gear no-load voltage ratio devices are installed on the make-up machine, and the undergauge and the rolled thread of workpiece (10) are once finished; The power drive dedicated hydraulic undergauge mechanism action of Hydraulic Station (14) to requiring size, falls into the unidirectional undergauge of workpiece (10) one ends rolled thread hydraulic tongs (11) through jacking displacement frame (13) conversion station and clamps, and changes the rolled thread operation over to; The power footpath driving pulley (2) of motor (1), V-belt (3), driven pulley (4) are delivered to infinite variable speed hard flank of tooth decelerator (5), drive special-purpose three output planetary gear no-load voltage ratio devices by the driving gear (6) that is installed on decelerator (5) output shaft, pass to cylindrical die roll (9) by universal joint (8) again, around extruding rolled thread of workpiece (10) external diameter and active autobiography, under the operating mode that workpiece (10) maintains static, make screw thread; Switch board (15) and computer touch screen (37) is housed on the frame (12), and complete machine adopts digital control and automatic conversion station.In special-purpose three output planetary gear no-load voltage ratio devices, driven gear (7) couples together into a disc with door (24) with SOC.HD. cap screw (30), its center fixed gear shaft (29), gear shaft (29) is supported on the bearing I I (27) that is set in disc and bearing I II (31) goes up and with an axle usefulness collar I (32), clamp nut (33) and bearing gland (28) are made axial restraint, the gear shaft that maintains static (29) and uniform three planetary gears (25) engagement, planetary gear (25) is supported on the roller bearing (35), the bearing I (26) that is set in disc that is supported on roller bearing (35) goes up and with bearing collar (34), axle is made axial restraint with collar II (36), do 360 ° of runnings continuously along gear shaft (29) in the time of planetary gear (25) rotation, drive universal joint (8) rotation hinged, drive cylindrical die roll (9) workpiece (10) is carried out extrusion process with roller bearing (35).In the dedicated hydraulic undergauge mechanism, the fore-stock (17) that couples together by guide shaft (16), medium-height trestle (19) and after-poppet (21) are supported on the frame (12), locking hydraulic cylinder (18) is supported on the fore-stock (17), undergauge hydraulic cylinder (20) is supported on the medium-height trestle (19), clamp (22) is cemented on the after-poppet (21), after workpiece (10) is clamped by undergauge hydraulic tongs (23) and clamp (22), the power of Hydraulic Station (14) moves after driving the piston rod of locking hydraulic cylinder (18) earlier, drive undergauge hydraulic cylinder (20) action again, the one section undergauge that workpiece (10) one ends is needed rolled thread is to the size identical with the core diameter of thread.The present invention had both overcome traditional cutted thread and mantle fiber long processing time, inefficient drawback, changed the rolled thread technology that existing screw-rolling machine workpiece must together rotate with cylindrical die roll again, workpiece such as anchor pole, the foundation bolt etc. of a processing super long and an end abnormal shape easily, and undergauge and rolled thread are once finished, complete machine is realized digital control and automatic conversion station, efficient is improved more than three times, one man operation, time saving and energy saving, safe and reliable, novel in design, mechanism rationally, keep in repair easy, of many uses.
