Abstract
The invention discloses a drum brake production method through V-process casting. The drum brake production method adopts the process procedures of V-process, blending, loading, melting, pouring and cleaning. According to the drum brake production method, scrap steel is used as a raw material, and through the targeted adjustment and improvement of the process, the production cost is lower.
Description
Technical field
The present invention relates to a kind of V method casting Back-braking drum production method.
Background technology
The moulding of V method and V method (V--Process) are a kind of vacuum sealed molding casting methods, also known as vacuum moulding.Molding operation is complicated, and light casting moulding productivity ratio is not high.From moulding, mould assembly, cast until casting falling sand, all will keep negative pressure to casting mold, this brings certain difficulty to mechanization Production line.In addition, the percentage elongation of plastic sheeting and the restriction of formability, affect the expansion of this method range of application.
Drum brake is generally used for trailing wheel.Typical drum brake is primarily of parts compositions such as base plate, brake drum, brake-shoe, wheel cylinder (brake cylinder), return spring, alignment pins.Base plate is arranged on the fixed position of axletree, and it is fixed, and brake-shoe, wheel cylinder, return spring, alignment pin are housed above, bears rotary torsion during braking.Each drum has a pair brake-shoe, and brake-shoe has friction facing.Brake drum is then mounted on wheel hub, is the parts rotated with wheel, and it is made by the cast iron of certain deal, and shape is like garden drum type.When braking, wheelcylinder piston promotes brake-shoe compressing brake drum, and brake drum is subject to friction eceleration, forces wheel to stop operating.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of V method casting Back-braking drum production method.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of V method casting Back-braking drum production method, employing V method moulding--batching--charging--fusing--cast--technological process of cleaning.
Preferably, during described batching, adopt the pig iron: 75%, steel scrap: 15%, foundry return: 10%, is met the furnace charge of following chemical composition:
Percentage: C 3. 2 ~ 3.4%, Si 1.8 ~ 2.1%, Mn 0.70 ~ 0.9%, P < 0.15%, S < 0.12%, all the other are Fe.
V method casting Back-braking drum production method of the present invention, employing steel scrap is raw material, and by adjusting the specific aim of technique and changing near, production cost is lower.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
embodiment 1:
