Detailed description of the invention
Embodiment one:
The present embodiment is a kind of rolled thread thread rolling machine, as shown in Figure 1, 2.The present embodiment comprises: comprising: be arranged on the rolled thread wheels 1 on lathe bed 3 and one piece of screw plate 4 be arranged on lathe bed, described rolled thread wheels and described screw plate do relative motion.
The present embodiment changes one of traditional thread rolling machine piece of screw plate into rolled thread wheels, forms plane and rolls the screw thread process mode combined with rolling compaction.In thread rolling rolled thread process, the parallel motion of screw plate and cylindrical die roll periphery, forms screw plate and rolls motion the relative of cylindrical die roll outer round surface, workpiece 2 is between the two rolled out screw thread.Because rolled thread needs the support of at least three points, could by work-piece constraint in processing stations, so the rolled thread wheels described in the present embodiment are by two cylindrical die rolls (as shown in Figure 1), or a cylindrical die roll adds a support plate composition.Wherein, described support plate can change small-sized roller into, to reduce the frictional force to workpiece.Be arranged on a pair cylindrical die roll on lathe bed side by side, described cylindrical die roll and one piece of screw plate be arranged on lathe bed do relative motion, described two form triangle space between cylindrical die roll and screw plate, and as the position that dotted line in Fig. 2 represents, described triangle space is processing stations.
Rolled thread and thread rolling combine by the present embodiment, be triangle distributions by screw plate and two cylindrical die rolls, as shown in Figure 2, two cylindrical die rolls or a cylindrical die roll installation parallel with the rotating shaft of support plate, and the plane of screw plate is parallel with the axle of two cylindrical die rolls, but not in a plane.Screw plate and two cylindrical die rolls are in tangent situation, but can not be tangent, because tangent, are equivalent to create interference between the two, therefore, will have certain gap between screw plate and cylindrical die roll.This tangent and discontiguous situation between screw plate and two cylindrical die rolls (or support plate), make to form a triangle space between two cylindrical die rolls (or support plate) and screw plate, this triangle is two waists is the triangle of circular arc.These leg-of-mutton two circular arc waists are cylindrical die rolls, and base is then screw plate.Workpiece is just clipped in this leg-of-mutton space, as shown in Figure 1.
The present embodiment can be reequip on the basis of traditional thread rolling machine, and the position by former movable screw plate is replaced by rolled thread wheels.Therefore, the rolled thread thread rolling machine described in the present embodiment also has a series of setting such as lathe bed, dynamical system, feeding device that screw-rolling machine or thread rolling machine have, to carry out normal screw thread process.
Namely described screw plate can vertically be installed, and also can level install, and the entirety depending on whole lathe requires and specifically arranges.Corresponding rolled thread wheels can vertically be installed in (with regard to the direction of cylindrical die roll gyroaxis), also can level install.
For forming the relative motion between screw plate and rolled thread wheels, screw plate and cylindrical die roll have two kinds of mounting means at least: one is fixed by screw plate, and rolled thread wheels move back and forth; Another kind is fixed by rolled thread wheels, and screw plate moves back and forth.Namely or by screw plate be fixed on lathe bed, and rolled thread wheels be arranged on a slip blade, or on the contrary.These two kinds of modes respectively have pluses and minuses, can select as required.
No matter be screw plate motion, or the motion of rolled thread wheels, its motion all can use crank and rocker mechanism to drive slip blade, forms the relative motion of rolled thread wheels and screw plate.Also rack-and-pinion can be used to drive or adopt hydraulic system to drive slip blade.
No matter rolled thread wheels are fixing or slide, the formation of rolled thread wheels also has multiple choices:
Rolled thread wheels can the additional support plate of choice for use cylindrical die roll, and cylindrical die roll, support plate and screw plate form a leg-of-mutton space, are processed by work-piece constraint in this leg-of-mutton space.
All right choice for use two cylindrical die rolls of cylindrical die roll, these two cylindrical die rolls are same with screw plate can form a leg-of-mutton space, and constraint workpiece is processed.Support plate can select the support plate identical with traditional screw-rolling machine, also can be used in the support plate of the strong point (line) with rolling element, to reduce the friction of support plate to workpiece.
Two cylindrical die rolls can select the cylindrical die roll of two different-diameters, form a large cylindrical die roll, a little cylindrical die roll, or the cylindrical die roll that two diameters are identical.Owing to being subject to the impact of cylindrical die roll cylindrical curvature, the diameter range of choice of the workpiece that the cylindrical die roll that two diameters are identical can be processed is limited, and therefore, the cylindrical die roll using two diameters different can process the workpiece of how middle different-diameter.
Because cylindrical die roll needs power in rolled thread process, rack-and-pinion transmission can be carried out to cylindrical die roll.No matter whether rolled thread wheels move, can to pass on Gong cylindrical die roll with tooth bar.As rolled thread wheels are arranged on slip blade, just can tooth bar be fixed on lathe bed, rotate with rack drives cylindrical die roll.If rolled thread wheels are fixedly mounted on lathe bed, just can tooth bar be arranged on slip blade, cylindrical die roll can be driven equally to rotate.
When the cylindrical die roll that use two diameters are identical, the identical gear of two diameters can be set respectively on two cylindrical die rolls, and use a tooth bar that two cylindrical die rolls can be driven to rotate.If use the cylindrical die roll that two diameters are different, then the gear of different-diameter is set respectively on two cylindrical die rolls, uses the gear of tooth bar difference transmission two different-diameters of two different tooth pitches simultaneously.Also rack-driving cylindrical die roll can be used, then by another cylindrical die roll of gear drive.

Screw plate described in the present embodiment is fixing, and rolled thread wheels are then move back and forth, and is formed and rolls motion with the thread rolling of screw plate.Therefore, rolled thread wheels are arranged on slip blade, move back and forth, and are equivalent to the slip screw plate of traditional thread rolling machine.The motion of slip blade can drive with crank and rocker mechanism, also can be produced by hydraulic system or motor driven gear tooth bar.
While slip blade motion, cylindrical die roll also will rotate, to produce the effect of roll extrusion.Cylindrical die roll can transmit the rotation into cylindrical die roll by the motion of slip blade, the Special servo motor that also cylindrical die roll can be driven to rotate by installation on slip blade or stepper motor, so that synchronous with screw plate.Slip blade is moved back and forth the rotary motion being converted to cylindrical die roll, the transmission of rack-and-pinion can be used, i.e. stationary rack on lathe bed, cylindrical die roll is arranged and tooth bar meshed gears, namely when slip blade moves, the rotation being converted to cylindrical die roll will can be moved back and forth.
When rolled thread wheels have the cylindrical die roll of two different sizes, just need the gear of corresponding two different-diameters of tooth bar of two different moduluses.And when the diameter of two cylindrical die rolls is onesize, then can use a tooth bar, the gear that corresponding two moduluses are identical with diameter.
