Abstract
The invention discloses a method for manufacturing mechanical drive chain wheel by forging technology, which comprises the following steps: baiting, skinning, coating, heating, upsetting and extruding, annealing, ball blasting, parkerising, saponifying, gear shape cold finishing and finishing. In the method, the warm extrusion technology is adopted to carry out metal volume distribution, thus notonly overcoming waste of raw materials in the prior art, reducing manufacturing costs but also shortening production period and having stable manufacturing technique.
Description
Technical field
The present invention relates to the production method of mechanical drive chain wheel, especially relate to a kind of method with FMT manufacturing machine drive sprocket.
Background technology
In the prior art, mechanical drive chain wheel or gear are made of the central part and the gear teeth, the needs design can be installed according to operating mode in the central part two sides, large-scale transmission device requires drive sprocket or gear to have higher intensity and precision, mechanical drive chain wheel generally adopts machine-tooled method production, machine-tooled method manufacturing machine drive sprocket, gear have gear teeth advantage of high precision, but its production cycle is long, manufacturing cost is high.
Summary of the invention
The invention provides a kind of method with FMT manufacturing machine drive sprocket.
The present invention is achieved by the following technical solution:
The production method of mechanical drive chain wheel may further comprise the steps:
(1) blanking;
(2) peeling base scale removal;
(3) equadag coating anti-oxidation decarburizing;
(4) heating-temperature is controlled at 850-950 ℃;
(5) jumping-up extruding-the jumping-up extruding forms the sprocket wheel blank in the mold cavity of sealing, described sprocket wheel blank is made of the centre of sprocket portion and the gear teeth, described central part center is provided with axis hole, the side of described central part is provided with polygon step and cylindrical step, jumping-up extrusion modling centre of sprocket portion side cylindrical step in the mold cavity of sealing at first during the extruding of described jumping-up, one side cylindrical step is hollow step, forms inner chamber; Then the sealing mold cavity in the jumping-up extrusion modling centre of sprocket portion side polygon step and the gear teeth;
(6) anneal-be warming up to 760-780 ℃, be incubated 5 hours, the air cooling of coming out of the stove after being chilled to 450-500 ℃ with stove;
(7) ball blast, phosphatization, saponification;
(8) cold-finish wheel tooth outline-utilize die finish makes the wheel tooth outline reach the product drawing requirement;
(9) fine finishining makes drive sprocket reach the product drawing requirement.
The present invention utilizes the metal flow forming principle, adopt the jumping-up extruding of warm extrusion technology elder generation, in the mold cavity of sealing, form centre of sprocket portion and gear teeth blank, utilize die finish cold-finish wheel tooth outline again, make the wheel tooth outline reach the product drawing requirement, at last the central part and the gear teeth are done local fine finishining, make drive sprocket reach the product drawing requirement.
The invention has the beneficial effects as follows: the present invention is on the basis that guarantees drive sprocket gear teeth intensity and precision, according to the metal flow shaping characteristic, adopt the warm extrusion technology reasonably to carry out metal volume distribution, both overcome the phenomenon of prior art waste of raw materials, reduced manufacturing cost, shortened the production cycle simultaneously, and stable processing technique.
