[specific embodiment]
Mainly reaching specific embodiment below in conjunction with the accompanying drawings further describes in detail THREAD ROLLING DIES.
Rolling the tooth machine is the special mechanical equipment of producing the excircle screw thread.The operation principle of rolling the tooth machine is, uses two screwed THREAD ROLLING DIESs to push workpiece to be processed, makes the outer round surface generation plastic deformation of workpiece, forms screw thread.
The THREAD ROLLING DIES 100 of Fig. 1, an embodiment shown in Figure 2, promptly be used for rolling tooth machine excircle to machined part carries out roll extrusion so that to be processed produce plastic deformation, to be processed excircle forms and the opposite shape of THREAD ROLLING DIES 100 tooth forms.THREAD ROLLING DIES 100 comprises the gear wheel portion 110 of column and is located at the column alignment portion 120 at column gear wheel portion 110 two ends.Other preferred embodiment in, alignment portion 120 can also be only in end settings of gear wheel portion 110, guarantee that the termination rolls the axiality of tooth product and circle and beat etc. and to meet the product quality requirement.
Preferably, the design that is formed in one of the gear wheel portion of present embodiment 110 and alignment portion 120, thus the machine-shaping of whole THREAD ROLLING DIES 100 is easier.
THREAD ROLLING DIES 100 offers along axis direction and is used for and rolls the affixed installing hole 130 of respective fixation device on the tooth machine, and further offers keyway 140 at the hole wall of installing hole 130 along the axis direction of THREAD ROLLING DIES 100.THREAD ROLLING DIES 100 in the present embodiment is provided with a square keyway 140, in other embodiments, for guaranteeing that THREAD ROLLING DIES 100 each several parts are stressed evenly in rolling the tooth process, can also be symmetrical arranged a plurality of square keyways 140.
The gear wheel portion 110 of present embodiment THREAD ROLLING DIES 100 is the roll threading structure, and in addition, gear wheel portion 110 can also be other tooth form structure, specifically states embodiment as follows.
