Abstract

The invention discloses a belt wheel flangeless forging process of an electromagnetic clutch of an automotive air conditioner. The process comprises the steps of: (1) blanking; (2) heating; (3) descaling; (4) mold forging; (5) trimming and shaping; (6) heat treatment; (7) shot blasting; (8) rust preventing treatment; and (9) packaging. A mold consists of an upper module and a lower module, and the service life is more than 20000 pieces; and an upper mold core is arranged in the upper module, and the service life is averagely about 3500 pieces. The maximal depth of a coil groove can be 2.5 times of the width of the coil groove. The process has the following beneficial effects: the service life of the mold can be prolonged; the coil groove of a produced belt wheel is deep; the pattern draft is small; the material utilization rate is high; the manpower and material resource costs are reduced; the production efficiency is improved; and the market competitiveness is enhanced.

Description

Automobile air conditioner electromagnetic clutch belt pulley non-trimming Forging Technology
Technical field
The present invention relates to automobile air conditioner clutch, particularly one is automobile air conditioner electromagnetic clutch belt pulley non-trimming Forging Technology.
Background technology
Automobile air conditioner electromagnetic clutch is a power transmission between automobile engine and automobile air conditioner compressor, automobile air conditioner compressor is driven by electromagnetic clutch by automobile engine, the kind of automobile air conditioner clutch is a lot, conventional electromagnetic clutch comprises driving-disc, belt pulley, magnetic coil, belt pulley is connected with automobile engine by belt, current automobile air conditioner electromagnetic clutch belt pulley market is large, be characterized in: coil groove depth is narrow, middle convex tendon is thin, be unfavorable for shaping in forging process, produce with conventional wrought processes, coil groove depth equals groove width at most, and die life is low, stock utilization is generally between 75%-85%, utilization rate of equipment and installations is low, personnel are more, production cost is relatively high.
Summary of the invention
For solving the problem, the object of this invention is to provide one and can extend die life, the pulley coil groove depth manufactured, pattern draft is little, stock utilization is high, reduce manpower and materials cost, enhance productivity, the automobile air conditioner electromagnetic clutch belt pulley non-trimming Forging Technology of enhancing one's market competitiveness.
For achieving the above object, technical scheme of the present invention is:
Automobile air conditioner electromagnetic clutch belt pulley non-trimming Forging Technology, comprises the following steps,
(1) blanking: be the blank of given size by the blanking of 45Cr or 42CrMo steel body;
(2) heat: blank is sent to intermediate frequency furnace and heats, to hot forging temperature;
(3) descale: adopt jumping-up mode scale removal;
(4) die forging: be positioned over by the blank after descale on special forging equipment and utilize mould forging forming, forms coil groove and through hole;
(5) trimming, shaping: trimming, Shape correction are carried out to the forging after die forging;
(6) heat treatment: the forging after trimming, shaping is heat-treated;
(7) ball blast: utilize shot-blasting machine to carry out Shot Blasting to forging;
(8) antirust treatment;
(9) pack.
As preferably, described mould comprises upper module and lower module, reaches more than 20000 service life, establishes upper mold core in upper module, service life average out to about 3500.
As preferably, maximum 2.5 times of reaching coil well width of the degree of depth of described coil groove.
Compared with prior art, beneficial effect of the present invention: can extend die life, the pulley coil groove depth of manufacture, pattern draft is little, and stock utilization is high, reduces manpower and materials cost, enhances productivity, enhance one's market competitiveness.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Fig. 2 is the structural representation of belt pulley.
Wherein 1: pulley body; 2: coil groove; 3: through hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, 2, automobile air conditioner electromagnetic clutch belt pulley non-trimming Forging Technology, comprises the following steps,
(1) blanking: be the blank of given size by the blanking of 45Cr or 42CrMo steel body;
(2) heat: blank is sent to intermediate frequency furnace and heats, to hot forging temperature;
(3) descale: adopt jumping-up mode scale removal;
(4) die forging: be positioned over by the blank after descale on special forging equipment and utilize mould forging forming, forms coil groove and through hole;
(5) trimming, shaping: trimming, Shape correction are carried out to the forging after die forging;
(6) heat treatment: the forging after trimming, shaping is heat-treated;
(7) ball blast: utilize shot-blasting machine to carry out Shot Blasting to forging;
(8) antirust treatment;
(9) pack.
Described mould comprises upper module and lower module, reaches more than 20000 service life, establishes upper mold core in upper module, service life average out to about 3500.Maximum 2.5 times of reaching coil well width of the degree of depth of described coil groove.Maximum 2.5 times of reaching coil well width of coil groove depth, and die life is high, the service life of upper module and lower module reaches more than 20000, upper mold core average out in service life about 3500.Module is less than common process, it mainly decreases mould and meets strike, 99% of effective hitting power perform to product shaping in go, the feature of the belt pulley produced is: coil groove depth, and pattern draft is little, and stock utilization reaches 97.5%, equipment reduces to 4 by original 6, personnel reduce to present 4 by original 7, and class's output, by original 1500, brings up to 2600.Greatly reduce cost, improve production rate, enhance the market competitiveness.The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite of not de-the technology of the present invention principle; can also make some improvement and modification, these improvement and modification also should be considered as the protection domain invented.
