Description
One, technical field
Engineering machinery
Two, background technique
Currently, during building construction, before pouring concrete, fixed shear wall, the overall length screw rod of beam column template；Extinguishing pipe
The sunpender in road and finishing furred ceiling, scene is all outsourcing, live cannot be processed.It due to elongated, preferably damages, cannot repair,
Waste is big, and the low deformation of screw thread silk head intensity keeps nut difficult to install.
In the future, assembled architecture house needs a large amount of various non-standard high-strength screw rods.Using cold extruding technique, existing
The field processing non-standard high-strength screw rod of various specifications, is the needs of construction industry development, meanwhile, material is saved, cost is reduced, subtracts
Little waste.
On the basis of " the asynchronous screw-rolling machine design principle " of my invention:
1, thread technology is processed using cold extrusion, improves screw strength.
2, cylindrical die roll is fixed in same structure body, reduces equipment moving system, increases equipment integral rigidity and work
Make reliability.Structure is simple, low cost, convenient to install and maintain, is suitble to site operation.
3, it is to be incremented by curved line that some, which is radius of a circle, on cylindrical die roll circumference, and cylindrical die roll turns around, while band is started building
Part is turn-taked, and workpiece screw thread squeezes to be formed, and revolving speed is slow, safe operation.
4, cylindrical die roll lead angle can be different from workpiece to be machined lead angle, and screw pitch is completely the same, replacement rolling
The non-standard high-strength screw rod of two or more specifications can be processed in silk wheel and Support bracket, a screw-rolling machine, and reducing building-site makes
Use number of devices.
Three, inventive principle content
1, in screw thread squeezing tank driving shaft and driven shaft through sliding bearing loop same extruding cabinet, driving shaft and from
Without movement close to each other between moving axis, driving shaft and the synchronized rotating Vortex of driven shaft are only made by actuating unit.(figure
1)
2, driving shaft and driven shaft one end dress have a mistake between two gears there are two the identical gear of technical parameter
Cross gear.
3, there are two the identical cylindrical die rolls of technical parameter for driving shaft and driven shaft other end dress, adjust two rolled thread
The screw thread peak of wheel, which is staggered, is displaced just half pitch, then adjusts Support bracket height, centering is through qualified workpiece to be machined
Material is squeezed (cutting), while guaranteeing the quality of workpiece to be machined.
4, cylindrical die roll screw pitch and workpiece to be machined screw pitch are completely the same.
Cylindrical die roll lead angle can be completely the same with workpiece to be machined lead angle, can also be inconsistent.When complete one
When cause, workpiece to be machined is without axial movement；When there is inconsistency, workpiece to be machined has axial movement.
5, have on cylindrical die roll circumference: feeding part；Crimping section；Correction portion；Exit part.It (feeding part and exits
Part is formed together recess portion)
It is placed on the recess supports bracket between two cylindrical die rolls adjusted through qualified workpiece to be machined material in the middle,
Cylindrical die roll need to only rotate a circle, and under the squeezing action of two cylindrical die rolls, workpiece to be machined metal material be made to generate plastic deformation,
It is automatically exited from after forming screw thread.
6, cylindrical die roll, which need to only rotate a circle, can process screw thread, and revolving speed is very slow, be typically chosen 6~10 turns of (roots per minute
Torque value design needed for being plastically deformed is generated according to the screw thread length and specification of workpiece to be machined).
Revolving speed is greatly reduced on the general screw-rolling machine of workpiece to be machined rotating ratio, is overcome because revolving speed is too fast, and elongate threaded screw is held
Easily get rid of curved defect, construction safety.
Carry on the back the asynchronous screw-rolling machine design major parameter citing of shovel:
1, workpiece to be machined and cylindrical die roll member and main geometric and two cylindrical die roll centers away from
Note: two cylindrical die roll centers away from in=cylindrical die roll through passing through -0.3 in+workpiece, to guarantee that workpiece to be machined (is cut in extruding
Cut) screw thread when do not held out.
2, the asynchronous cylindrical die roll circumference geometry branch (Fig. 2) of shovel is carried on the back
(1) recess portion circumference is less than the cylindrical die roll core diameter of thread (being made of together feeding part with part is exited)；
(2) squeeze (cutting) part (circumferential section radius is the cumulative curved line of radius)；
(3) correction portion (circumferential section is cylindrical die roll major diameter of thread).
Four, Detailed description of the invention
Fig. 1: 1, active cylindrical die roll, 2, Support bracket, 3 squeeze cabinet, 4, driving gear, 5, transition gear, 6, engagement
Device one, 7, connector two, 8, Double cycloid gear reductor, 9, cushion block one, 10, cushion block two, 11, connecting plate, 12, motor.
Fig. 1 schematic illustration: Fig. 1 is the back asynchronous screw-rolling machine assembling figure of shovel
Fig. 2: (1) recess portion part circumference is that arc-shaped (2) squeeze (cutting) part (3) correction portion
Note: 1, the arc-shaped radius of the recess portion part≤cylindrical die roll core diameter of thread/2；
2 ,/2 are passed through in half warp of I-I section arc=cylindrical die roll screw thread；
3, I-I → II-II → III-III section arc half is cumulative half warp；
4., the arc-shaped radius of III-III → IV-IV section=cylindrical die roll Major Diam/2.
Fig. 2 is the back asynchronous screw-rolling machine design schematic diagram of shovel (abstract of description attached drawing)
Figure of abstract 2 illustrates:
1, it is passed through outside two cylindrical die rolls correction part arc length >=π x workpiece to be machined screw forming；Two cylindrical die roll recess portion parts
Arc length guarantees workpiece charging and exits.
2, two cylindrical die roll centers away from in=cylindrical die roll screw thread through passing through -0.3 in+workpiece screw thread, to guarantee workpiece in compacting spiral shell
It is not extruded and holds out when line.
3, the screw thread peak for adjusting two cylindrical die rolls, which is staggered, is displaced just half pitch.
4, Support bracket height is adjusted, guarantees workpiece to be machined quality.
5, workpiece to be machined profile outer diameter must assure that in workpiece to be machined pitch diameter of thread error range.
Five, specific embodiment
To guarantee two cylindrical die roll screw thread geometric dimension errors and error in geometrical form is completely the same and workpiece to be machined screw thread
Quality:
1, two cylindrical die roll screw threads simultaneous processing must shape on same lathe.
2, after being heat-treated, the cumulative circular arc shaped portion of two cylindrical die roll outer circles simultaneous processing on same numerically control grinder.
3, two cylindrical die roll recess portions simultaneous processing on same lathe, after heat treatment on same grinding machine simultaneous processing.
4, the other technical parameters of two cylindrical die rolls, material and processing method are the same as common cylindrical die roll.
5, two cylindrical die rolls, Support bracket, squeeze cabinet, driving gear, and transition gear should meet design requirement.
6, Support bracket material and hardness are consistent with two cylindrical die rolls；Height should indicate workpiece to be machined specification after adjusting,
It numbers consistent with cylindrical die roll.
7, actuating unit and motor should be generated according to the screw thread of compacting is plastically deformed required torque capacity selection.
It is recommended that: Double cycloid gear reductor is selected, small in size, light-weight, low noise, structure is simple, convenient to install and maintain.Pay attention to
Explanation of ordering goods is read, overload protection arrangement should be installed.
8, coolant liquid or lubricating oil, ne-leakage should be able to be stored in squeezing tank body.
