Abstract
The utility model discloses a chuck device for a roll formed thread-pipe. In the prior art, a thread-pipe is processed by means of cutting mostly, which wastes time, labors and materials. The utility model provides the novel chuck device composed of a circular chuck tyre. Three or more than three chuck claws are uniformly arranged on the chuck tyre, and a roller is fixed on each chuck claw by a small shaft. The dimension of the chuck claw is determined by the processed thread line, and the middle part of each roller is provided with a convex wheel blade. The processed workpiece is formed once in the mode of surface rolling through rollers, which saves time, labors and materials and provides the key equipment for the processing of the thread-pipe.
Description
The utility model relates to a kind of new chuck assembly of screwed pipe roll forming.
In prior art, the machined into screwed pipe mainly adopts the method for lathe tool cutting, to select for use than the poor dark 2 times of thick straight tube material of screwed pipe, through cutting into screwed pipe, process time-consuming like this and the expense material.
The novel purpose of this practicality provides a kind of aiming at and produces the matching used chuck assembly of screwed pipe, after installing this chuck assembly additional, this process equipment promptly can carry out the moulding of roll extrusion time processing to the straight tube material that meets the requirement of screw-type linear dimension, needn't on lathe, cut again, thereby the saving of labor, save time, the more important thing is material-saving.
" screw die " principle of using on the screwed pipe roll forming chuck assembly provided by the utility model, its operation principle and lathe is similar, and its difference is that just " screw die " is " sword is cut " to workpiece, and the pair of rollers workpiece of this device is " blunt cutting ".
Chuck assembly of the present utility model is made up of garden shape chuck tire, evenly arranging the Special disc pawl more than three and three on the chuck tire, on each dish pawl, fix a roller with little axle, the selected material of each roller all has certain intensity, the diameter of each roller is identical with thickness, and its size is decided with the requirement of the screw thread molded lines of processing.All there is a wheel sword that protrudes at the middle part of each roller, and the thickness of its projection is equal to the poor dark of the screw thread molded lines processed, and each diameter of taking turns garden, sword end arc does not wait, and increases successively, and its maximum equals the poor wide of institute's machining screw molded lines.
Each roller setting angle on the dish pawl is evenly arranged by the pitch of screw thread molded lines requirement, makes work piece by the angle of thread feeding of adjusting.
The chuck tire has the hole, garden to the general similar centre of chuck assembly, so that processing work is installed.Chuck assembly passes through the bracing or strutting arrangement of planker, bent plate composition on the guide rail of lathe bed, and it is mobile to guarantee that chuck assembly can come and go thereon.
When using the utility model machining screw pipe, workpiece one end of required processing is anchored on the spindle chuck of process equipment, the other end is by the hole, garden, chuck tire middle part of this chuck assembly, simultaneously according to the requirement of machining screw molded lines, the roller that processing is fit to, be installed on the dish pawl, and according to the screw-type linear dimension adjust and replacing dish pawl and on roller, selective pan pawl setting angle and select the change gear of spindle chuck rotation to count ratio.After the parameter adjustment, the processing of the roller on chuck assembly dish pawl extruding, start this processing unit (plant) then earlier, spindle chuck drives the processing work rotation, the roller of dish on the pawl promptly by the angle of thread of adjusting the moulding of straight tube rolling and processing, reach the requirement of required screwed pipe.
This screwed pipe roll forming chuck assembly that the utility model provides, through using proof: the screwed pipe of being produced adheres to specification fully, process simple and easy to do, the production efficiency height, reduced production cost, technical economic benefit is obvious, is a kind of reasonable roll forming device that the machining screw pipe is produced.

An embodiment of the present utility model is shown in accompanying drawing 1～6.The lathe of screwed pipe roll forming chuck assembly is housed, and as shown in Figure 1, new chuck assembly of the present utility model (6) is supported on the guide rail (8) of lathe bed (1) by planker (4), bent plate (5).One end of processed workpiece-straight steel pipe (9) is fastened on the chuck (3), and spindle chuck (3) is contained on the head of a bed (2), regulates its rotary speed by change gear number ratio.The structure of new chuck assembly (6) is shown in Fig. 2-6.On garden shape chuck tire (10), arrange three dish pawls (11) equably, go up with the fixing assembling of little axle (a 12) roller (13) at each dish pawl (11), the used steel of each roller (13) are all through Overheating Treatment, to increase its intensity, the diameter (D) and the thickness (H) of roller (13) are decided with the requirement of machining screw molded lines.There is a wheel sword (14) that protrudes at the middle part of each roller (13), the thickness (h) that the wheel sword (14) of each roller (13) protrudes is equal to the poor dark of institute's machining screw molded lines, each takes turns the garden arc dia (d) of sword (14) ledge, and each is unequal, increase successively, but maximum diameter is equal to the poor wide of screw thread molded lines, as process a pitch and be 35mm, poor dark be 2.5mm, poor wide during for the 5mm screwed pipe, its D=30mm, H=16mm, h=5mm are if the ledge diameter that adopts three rollers then to take turns sword (14) can be selected d for use
1=1.5mm, d
2=2mm, d
3=2.5mm, the setting angle of three rollers (13) on three dish pawls (11) can evenly be arranged by the pitch (35mm) of screwed pipe molded lines requirement, make work piece by the angle feeding of adjusting.In the centre of chuck tire (10) hole, garden (15) is arranged, so that the workpiece of processing is by wherein carrying out rolling and processing.Jackscrew (16) is arranged in order to fixing little axle (12) on the dish pawl, the end little (12) is equipped with grease cup (17), in order to the sliding surface of oily roller and little axle.
When adopting the utility model to carry out the machining screw pipe, at first according to the screw thread molded lines requirement of processing, select suitable roller (13), then workpiece-straight steel pipe (9) one ends are clamped on the spindle chuck (3), the other end of workpiece passes the hole, garden (15) at chuck tire (10) center, adjust the dish pawl (11) on the chuck tire (10), make roller (13) on dish pawl (11) by the pitch requirement of institute's machining screw molded lines, arrange different angles, and be squeezed on the straight steel pipe to be processed (9).After selecting suitable change gear number ratio at last, start lathe and drive processed straight steel pipe (9) rotation by spindle chuck (3).At this moment the roller (13) on the dish pawl (11) that chuck tire (10) is installed is promptly by the requirement of screw thread molded lines, roll extrusion steel pipe continuously, time processing moulding
Present embodiment rationally and has fast been finished the machining screw pipe since installation utilization is put into production, the requirement of a roll forming has been accomplished to save time, saving of labor, material-saving, and whole production improves many times of work efficiency, and has saved a large amount of steel.Produced significant technical economic benefit.Because operation of the present utility model has solved the technical difficulty of screwed pipe processing, the batch process for improving the thermal efficiency, saving the New-type boiler of steel provides crucial process equipment.
