Abstract
The invention discloses a stand-alone continuous ring-making process of an engine gear ring blank, comprising the following steps: a, penetrating a barstock from a guide plate under action of feeding rollers; b, when the barstock is contacted with a groove at the front end of an upper ring diameter rod and a lower ring diameter rod, forming three friction points on the outlet of the guide plate, the upper ring diameter rod and the lower ring diameter rod respectively; forming a helix gear ring blank due to bending and deformation under action of limiting and guiding of the three friction points; and c, cutting the barstock off with coordination of a mandrel when the feeding mechanism stops feeding and the cutter mechanism starts to operate. By adopting the manufacturing process of the engine gear ring disclosed by the invention, processing precision of the gear ring is improved, raw material waste is reduced, manufacturing cost is saved, rate of finished products is greatly improved and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of manufacturing process of engine ring gear blank, specifically, relate to a kind of engine ring gear blank unit and make ring technology continuously.
Background technology
In the prior art, the ring gear blank is that the carbon steel bar by the square-section is rolled into single annular, through butt welding; Remove slag; Annealing forms, when curling owing to be to curl one by one, thereby in that all the other partly are big near two ends ratio of curvature partly with the bar of slightly being longer than the ring gear circumference; Through also relatively poor, so have to increase allowance to the circularity of postwelding.
Because ring gear is to make ring one by one, therefore, the precision of ring gear processing is difficult to guarantee that allowance is big, the waste raw material, and high to workman's technical merit requirement, working strength of workers is high, and equipment has high input, and production efficiency is low.
Summary of the invention
To above-mentioned deficiency of the prior art, it is a kind of simple in structure that the present invention provides, and improves the machining accuracy of ring gear, reduces waste of raw materials, and a kind of engine ring gear blank unit of enhancing productivity is made ring technology continuously.
A kind of engine ring gear blank unit is made ring technology continuously, comprises the steps:
A, under the effect of feeding roller, bar penetrates from guide plate;
B, when bar is run into the groove of upper and lower circle footpath bar front end, form 3 friction points in guide plate outlet and bar place, upper and lower circle footpath respectively, flexural deformation under the spacing and guide effect of these 3 friction points, formation helical form ring gear blank;
C, feed mechanism stop feeding, and cutter mechanism produces action, under the cooperation of mandrel, cut off bar.
Said upper and lower circle footpath bar can move in chute separately, through controlling the position of upper and lower circle footpath bar, just can control the size in turn footpath.
Saidly bend in the process of helical form ring gear blank at bar, bar touches the inclined-plane of pitch bar, and the pitch bar can move along the axis direction of helical form ring gear blank winding shaping, forms the pitch of helical form ring gear blank.
It is wide that said roller surface is provided with 10-15mm, the groove that 5mm is dark.
The beneficial effect of the relative prior art of the present invention:
Engine ring gear manufacturing process of the present invention, the machining accuracy of raising ring gear reduces waste of raw materials, practices thrift manufacturing cost, and yield rate increases substantially, and enhances productivity.

The specific embodiment
Followingly the present invention is carried out detailed explanation with reference to accompanying drawing and embodiment:
Engine ring gear blank unit of the present invention is made ring technology continuously, comprises the steps:
A, under the effect of feeding roller 1, bar 3 penetrates from guide plate 2;
B, run into when bar 3 go up circle footpath bar 5, down during the groove of circle footpath bar 4 front ends; Directly bar 5, following circle directly form 3 friction points in bar 4 places to reach circle in guide plate 2 outlets respectively; Flexural deformation under the spacing and guide effect of these 3 friction points forms helical form ring gear blank;
C, feed mechanism stop feeding, and cutting knife 7 produces action, under the cooperation of mandrel 6, cut off bar.
Said upward circle footpath bar 5, following circle directly bar 4 can move in chute separately, through controlling the directly position of bar 4 of circle footpath bar 5, following circle, just can control the size in turn footpath.
Saidly bend in the process of helical form ring gear blank at bar, bar touches the inclined-plane of pitch bar 8, and pitch bar 8 can move along the axis direction of helical form ring gear blank winding shaping, forms the pitch of helical form ring gear blank.
It is wide that said roller surface is provided with 10-15mm, the groove that 5mm is dark.
Engine ring gear manufacturing process of the present invention, ring gear blank production line are carried out five volume rings continuously, produce in batches because this line can adapt to many kinds, and changing variety production only needs the short time to accomplish.
The bar of square-section, its length are slightly more longer than five times of ring gear circumferences approximately, during the volume ring; Its bin from volume ring machine is sent to, and six roller surface of rotating synchronously all have 10-15mm wide, the groove that 5mm is dark; In order to bite rod feeding; Make it non-slip, when adjusting the driven pulley center, can roll out the ring base of different-diameter with respect to the driving wheel center.
Engine ring gear manufacturing process of the present invention, the machining accuracy of raising ring gear reduces waste of raw materials, a kind of engine ring gear manufacturing process of enhancing productivity.
