Abstract
The present invention relates to metallurgical mining machine, gold mining machinery particularly, in machined steel-rubber compound sieve plate process, adopt metal post pendulum alive hole to go into mould, vulcanize composite molding at regular hour, temperature, pressure condition, steel-rubber compound sieve plate that this new method is made next time, has the pull-off strength height, advantages such as body is light, wear-resisting, percentage of plugged hole is low, energy-conservation can improve 2～3 times of work efficiency simultaneously, and the method is applicable to the various metallurgical mines of processing steel-rubber compound sieve plate.
Description
The present invention relates to metallurgical mining machine, particularly gold mining machinery.
The cylinder sieve plate is the critical piece of gold dredger drum sieve, continues to use metal foil for many years always and makes.Because the wearing no resistance of steel plate, noise is big, body weight, and the installation and maintenance difficulty, shortcomings such as energy consumption height, and the method for using steel plate and rubber two-layer compound instead is made the cylinder sieve plate.Promptly make outer skeleton with steel plate, rubber is made the inner liner abrasive resistant layer.Usually the rubber of earlier steel plate being holed presses the hole afterwards to hole cold bonding moulding.Could make camber base plate fixed leg form multiple angles to sticking because steel plate and rubber all need to bend to camber, cause steel plate not thread down, therefore give and cause very big difficulty gluing.And with the bonding compound cylinder sieve plate percentage of plugged hole height of this kind method, pull-off strength is low and influenced service life.
The objective of the invention is to: a kind of wear-resisting, pull-off strength is high, body is light, noise is little steel-rubber composite pillar of screen plate one-step moulding method is provided.
This method step is: the natural rubber of plasticating; Close refining with butadiene rubber; Compounding ingredient is handled in processing; Cooperate with compounding ingredient; Mixing; The slice moulding; The cutting steel plate; Boring; Curved arc; Rust cleaning; Coating adhesive; Post alive is put with the location, hole in steel plate boring back, the lay film above the post of living; Go into mould; The press cure moulding; The demoulding; Cleaning.
Said post alive is the cylinder that metal material is made.
The present invention has wear-resisting, the pull-off strength height, and percentage of plugged hole is low, changes to be welded as connecing, and installation and maintenance are easy, cut down the consumption of energy, and can improve advantages such as 2～3 times of working (machining) efficiencies.
Accompanying drawing 1 is that the master of sieve plate process of the present invention looks generalized section;
Accompanying drawing 2 is front views of post alive among the present invention;
Accompanying drawing 3 is vertical views of post alive among the present invention;
Accompanying drawing 4 is to use the present invention to process the schematic top plan view of finished product sieve plate.
Most preferred embodiment:
1, sheet rubber preparation:
Natural rubber 70% closes refining evenly with 30% butadiene rubber after plasticating in 15～20 minutes, survey plasticity and should reach 0.30 ± 0.02(p) this moment.Compounding ingredient has Sulfur, accelerant C
2, altax, zinc oxide, stearic acid, antioxidant D FC-34, antioxidant 4010, paraffin wax, ancient Malong, intermediate super abrasion furnace black, vaseline, turpentine oil.Wherein Sulfur 1.2, accelerant CZ 0.6%, altax 0.3%, zinc oxide 5%, stearic acid 2%, antioxidant D PC-34 1.5%, antioxidant 4010 0.5%, paraffin wax 1%, ancient Malong 2%, intermediate super abrasion furnace black 45%, vaseline 3%, turpentine oil 4%.Drying is pulverized the back and is cooperated, and adopts the sulfur vulcanization system to make rubber vulcanization produce polysulfide bond, to obtain high resiliency, adds intermediate super abrasion furnace black again and cooperates as reinforcing agent, and mixing even slice is stand-by on rubber mixing machine.
2, steel plate preparation:
Press rotary strainer plate (9) required specification cutting steel plate (1); By required sieve aperture (8) diameter and density boring; Steel plate (1) is bent to required camber, derusting by sandblasting.
3, composite molding:
Go into counterdie (6), smoothen adhesive (3) JQ-1 in steel plate (1) inboard; In sieve aperture (8), put post alive (4), go up lay film (2), go into middle mould (7), patrix (5) at the post (4) of living.Add temperature to 130 ℃～150 ℃.Plus-pressure is to every square centimeter more than 15 kilograms, press every millimeter thickness of film (2) about 10 minutes computing time a sulfidization molding.
Afterwards, the demoulding, cleaning check, warehouse-in.
The post alive (4) that uses can be made into cylinder with various metals, and its height, diameter need to decide on sieve plate (9), can reclaim with the post of finishing alive (4) again and use repeatedly.
Claims (2)
1, a kind of steel-rubber composite pillar of screen plate once moulding method, it comprises the natural rubber of plasticating; Close refining with butadiene rubber; Compounding ingredient is handled in processing; Cooperate with compounding ingredient; Mixing; The slice moulding; The cutting steel plate; Boring; Curved arc; Rust cleaning; Coating adhesive; It is characterized in that: post alive is put with the location, hole in steel plate boring back; Top lay film; Go into mould; The press cure moulding; The demoulding; Cleaning.
2, the method for claim 1 is characterized in that: said post alive is the cylinder that metal material is made.
