Abstract
The invention provides an integral belt pulley spinning process, and relates to the field of belt pulley machining process. The steps of the process include adopting steel plates to feed; forming the middle shaft sleeve part by stretching and upsetting; after the middle shaft sleeve part is formed, stretching; then spinning, and obtaining a belt pulley prototype; positioning as the groove of the belt pulley, and turning the bore of the shaft sleeve. The process has the advantages that the product is integral, seams are eliminated; raw material is saved, and machining cost is reduced; the machining strength of products is improved, and rigidity is also improved; welding is omitted, stress produced by welding is eliminated, and mechanical properties are improved greatly.
Description
Technical field
The present invention relates to belt wheel processing technology field, be specifically related to the technique of integrated rotating pinch roller.
Background technology
Spin pulley is all to adopt steel plate to carry out blanking, stretching, mould pressing, again through welding together with axle sleeve, the welding stress causing while easily producing welding, or fatigue fracture, these belt wheels are applied in the parts of steering pump of automobile or other machine driving pump impeller, apply extensivelyr, can cause serious quality accident like this, these problems are to be difficult to be resolved always.
A few days ago, split type spin pulley is that the axle sleeve that belt wheel is connected with intermediate transmission is the easy generation shortcoming of separating:
While 1, welding, produce welding stress, easily produce fatigue fracture;
2, manufacturing procedure increases and wastes raw material;
3, whole strength ratio a little less than, easily produce distortion;
4, have weld seam, outward appearance is not very attractive in appearance;
5, the material of middle axle sleeve being there are certain requirements, must be mild steel.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing intensity to improve, the technique of the integrated rotating pinch roller that rigidity strengthens.
Technical problem to be solved by this invention realizes by the following technical solutions:
The technique of integrated rotating pinch roller, is characterized in that: its main technological steps is:
Step 1: adopt steel plate to carry out blanking;
Step 2: the stretched and upsetting formation by middle axle sleeve part;
Step 3: after middle axle sleeve is partially-formed, redraw band wheel body;
Step 4: then carry out spinning with spinning machine, obtain belt wheel blank;
Step 5: the belt wheel of moulding is sent into and carried out solution aging processing in heat-treatment furnace;
Step 6: the groove of belt wheel of take is location, turning inner hole of shaft sleeve;
Step 7: check;
Step 8: packing warehouse-in.
The length-to-diameter of described jumping-up part should be less than 2.5, and it is smooth and vertical with axis that blank end face is wanted, and forging firmly will be just.
Described spinning is stable is controlled at 410 ℃-460 ℃, and the spinning time is 3-4 minute.
Described heat treatment is mainly shrend, and the water time is 3-7 second.
The invention has the beneficial effects as follows:
1, product monoblock type, does not have weld seam;
2, save material, cut down finished cost;
3, the processing intensity of product has improved, and rigidity strengthens;
4, not welding, the stress that does not exist welding to produce, mechanical performance improves a lot.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
The technique of integrated rotating pinch roller, its main technological steps is:
Step 1: adopt steel plate to carry out blanking;
Step 2: the stretched and upsetting formation by middle axle sleeve part;
Step 3: after middle axle sleeve is partially-formed, redraw band wheel body;
Step 4: then carry out spinning with spinning machine, obtain belt wheel blank;
Step 5: the belt wheel of moulding is sent into and carried out solution aging processing in heat-treatment furnace;
Step 6: the groove of belt wheel of take is location, turning inner hole of shaft sleeve;
Step 7: check;
Step 8: packing warehouse-in.
The length-to-diameter of jumping-up part should be less than 2.5, and it is smooth and vertical with axis that blank end face is wanted, and forging firmly will be just.
Spinning is stable is controlled at 410 ℃-460 ℃, and the spinning time is 3-4 minute.
Heat treatment is mainly shrend, and the water time is 3-7 second.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
