Abstract
The invention discloses a metal mold for a hammer ring of a coal breaker, belonging to the design and manufacture of metal molds of casting industry and the technical field of metal smelting and casting; the metal mold comprises a mold body and a pair of handles; the handles are symmetrically inserted at two ends of the outer surface of the mold with respect to the axis of the mold body; the metal mold is characterized in that eight T-shaped slots are evenly distributed in the inner cavity of the mold body; inserts are embedded in the T-shaped slots; the upper ends of the inserts are configured into external T shapes, which are matched with the T-shaped slots on the mold body; the parts of the lower ends of the inserts protruding out of the T-shaped slots are wedge shapes, wherein the included angle of the wedge shape is 64.81 degrees, the vertex angle of the wedge shape is arc with the arc radius of 6mm; the centre of the T-shaped upper surfaces of the inserts are provided with a concave conical surface. The invention aims to prolong the service life of the mold and reduce the production cost, so as to mostly enhance the economic benefit of the industries.
Description
Technical field
The metal die that the invention belongs to casting industry manufactures and designs, and belongs to the metal smelt casting technology field.
Technical background
The hammer ring is for parts on the coal breaker of thermal power plant.The environment for use very severe of hammer ring, in use procedure, the rate of wear is than very fast, and the hammer number of rings amount that therefore annual thermal power plant consumes is very large, and its market demand is huge.Produce the foundry enterprise of hammer ring in order to satisfy the huge market demand, generally adopt metal die Foundry Production hammer ring.Adopt metal die production hammer ring production efficiency higher, production cost is lower, therefore can reduce largely the production cost of hammer ring.
At present, what foundry enterprise adopted is the monoblock type metal die, and mold materials is cast iron (HT200).In process of production, the pouring temperature of molten steel is 1450 ℃-1500 ℃, and metal die is worked under hot conditions for a long time, easily produce tired and material is become fragile, particularly arrisdefect is easily damaged at the circular arc place of mold cavity, and cast iron die can not Welding Repair, therefore causes whole mould to be scrapped.The monoblock type metal die is more difficult in the timesharing of processing and manufacturing wedge shape inner cavity, and processing cost is higher.Be 1 year the service life of general cast iron metal die, need again make new mould after metal die is scrapped, and this has just increased the cost of metal die, thereby production cost is increased, and reduces economic benefit.Therefore, improve the service life of metal die, reducing production costs is of great significance improving the Business Economic Benefit tool.
Summary of the invention
The metal die that the present invention be directed to hammer ring product and design, purpose are in order to extend its service life, to reduce production costs, thereby farthest improve the economic benefit of enterprise.
The present invention is by realizing in the following manner:
A kind of coal breaker hammer ring metal die, comprise mold and a pair of handle, described this axis to handle and mold is the outer surface two ends that symmetry axis is plugged on mold, it is characterized in that: the inner chamber of mold is 8 the T-shaped grooves that evenly distribute, inlay in T-shaped groove and insert, the upper end of inserting is outer T-shaped shape, match with the T-shaped groove on mold, the part that the lower end grows T-shaped groove of inserting is wedge shape, wedged gap is 64.81 °, the drift angle of wedge shape is circular arc type, and arc radius is 6mm, and the T-shaped upper surface centre bit of inserting is equipped with the conical surface of an indent.
Advantage of the present invention is: original monoblock type metal die is changed over mold and the interchangeable metal die of two parts split of inserting, the monoblock type metal die is designed to the problem that the interchangeable metal die wedge of split tool can solve inner chamber wedge-like portion processing difficulties.Namely the machining of wedge shape die cavity is become T-shaped inner chamber, T-shaped inner chamber mechanical processing technique is simple, and the wedge shape die cavity partly can change, and carries out Welding Repair or changes and can continue to use if any damaging it to be taken off.So just greatly reduce production cost, can effectively improve the economic benefit of enterprise.

The specific embodiment:
Embodiment 1:
A kind of coal breaker hammer ring metal die, comprise mold 2 and a pair of handle 1, described this axis to handle 1 one molds 2 is the outer surface two ends that symmetry axis is plugged on mold 2, it is characterized in that: the inner chamber of mold 3 is 8 the T-shaped grooves that evenly distribute, inlay in T-shaped groove and insert 3,3 upper ends of inserting are outer T-shaped shapes, match with the T-shaped groove on mold 2, the part that 3 lower ends grow T-shaped groove of inserting is wedge shape, wedged gap is 64.81 °, the drift angle of wedge shape is circular arc type, and arc radius is 6mm, and 3 the T-shaped upper surface centre bit inserted is equipped with the conical surface of an indent.
In mould use procedure of the present invention, the damage of inserting, can repair at any time or change, the conical surface on top inserted works the effect of fixing to clamp, and it is C:0.35-0.50Mn that the present invention can adopt the chemical composition percentage of heat resisting steel ZG40Cr9Si2 :≤0.70Si:2.00-3.00 Cr:8.00-9.00P :≤0.035S :≤0.030.Adopt cast iron materials to make metal pattern and have a lot of shortcomings, the electric machining poor performance of cast iron is particularly very difficult during processing profiled die cavity.And the welding performance extreme difference of cast iron, metal die has when damaging can not Welding Repair, can only scrap.So, adopt heat resisting steel to make metal die and can solve these difficult problems.The machining property of heat resisting steel, electric machining performance and welding performance are all relatively good, and this makes processing cavity become easier, and heat resisting steel can Welding Repair, reuse, and therefore can effectively extend the service life of metal die.
The economic benefit situation analysis
Originally the manufacturing cost of metal die is 2600 yuan/part, and be 1 year its service life.The manufacturing cost of metal die of the present invention is 6400 yuan/part, and be 10 years its service life.Improve front metal die expense as 26000 yuan/10 years take 10 years as computation of Period, the die cost after improvement is 6400 yuan/10 years, can save 19600 yuan/10 years covers of die cost, and can save 1960 yuan of/year covers of die cost every year in 10 years.
In sum, reduce metal die and production cost the service life of adopting the technology of the present invention can effectively improve metal die, be of great significance improving the Business Economic Benefit tool.
