Abstract

The utility model relates to a rubber spring for a resonance vibration feeding machine, belonging to a shock absorbing element on a feeding machine. More than four layers of quadrate rubber blocks are laminated together with spaced aluminous plates and an upper and a lower bottom plates which are provided with mounting holes, the relative positions among the rubber blocks are successively shifted by a certain distance from one end, the components are bonded together by conventional binding technology. The utility model has the advantages of powerful bearing capacity, good effect of shock absorption, long service life, simple structure, low cost, easy application, etc. The running trial of sampling machines demonstrates that the utility model can completely satisfy the requirements for being used on resonance vibration feeding machines.

Description

Combined rubber spring for resonance vibration feeding machine

The utility model belongs to a kind of damping spring of feeder, the combined-type rubber spring that particularly a kind of inertia resonance vibrating vibrating feeder is used.

At present, in the colliery, in some production process of industries such as metallurgy, the equipment that need raw material be sent to or provide by technological requirement, what it was more advanced is the inertia resonance vibrating vibrating feeder, yet because of its main vibration spring can not satisfy at thousand oscillation frequencys of per minute, amount of compression is being worked under the mal-condition of compression stretching distortion under 14mm and the heavy lift repeatedly, be not less than 5,000 hours operating needs service life and influence it and promote the use of, for satisfying the main vibration spring of above-mentioned job requirement, a lot of units once made a large amount of experimentaies work, but all do not obtain satisfied result, have when unload test, because of the too high rubber spring explosion that causes that heats up of compression stretching repeatedly; What also have comes off voluntarily because of bonding reason makes rubber block in process of the test, and analyzing its failure cause is that rubber is selected materials and the key problem in technology of technique for sticking does not solve.

The purpose of this utility model provides and a kind ofly can satisfy above-mentioned service conditions and require rationally, and bonding firm long service life is simple in structure, cost is low be suitable for the resonating combined-type rubber spring of feeder.

The purpose of this utility model realizes by the following technical solutions, be that to select import 1# natural rubber and homemade butadiene rubber for use be that the rubber of Main Ingredients and Appearance is raw material, square rubber block through machine-shaping, with the square rubber block more than four layers and at interval aluminium sheet and have the folded mutually conventional technique for sticking, bonding forming used of upper and lower bottom plate of mounting hole.

Described square rubber block is when folding bonding mutually, and its position is from left to right in turn to the distance that moves down 8mm.

Described square rubber block is two groups of combinations, also can be one group, one and Ban or many group combinations.

The utility model compared with prior art because selection is reasonable, bonds firmly, so there is load-carrying capacity strong, good damping effect, not explosion, advantages such as long service life, simultaneously simple in structure, cost is low, implements easily, and is on probation through exemplar installation operation, can satisfy the operating needs of resonance feeder fully.

Fig. 2 is a side-looking structural representation of the present utility model.

Fig. 3 is the side-looking structural representation of the embodiment of the utility model one and Ban combinations.

Fig. 4 is the side-looking structural representation of another embodiment of the utility model.

Fig. 5 is the side-looking structural representation that the utility model is organized combination more.

Enforcement of the present utility model is described in conjunction with the accompanying drawings, selecting import 1# natural rubber or import 1# natural rubber and homemade butadiene rubber for use is that the sizing material of Main Ingredients and Appearance adds an amount of sulphur more respectively, diphenylguanidine m, reinforcing agent (zinc oxide or semi-reinforcing hydrocarbon black), dibutyl ester soften flux and aging inhibitor (4010 or D) are pressed compounding rubber, the common process of back mixing is prepared the used rubber of square rubber block 3, with the square rubber block 3 of machine-shaping sulfuration, four layers of two group and aluminium sheets 2 at interval and have mounting hole on, lower shoe 1 is folded mutually with conventional bonding the forming of bonding process.Its square blob of viscose 3 also can be one group, one and Ban or the many groups of rubber springs that are combined into side by side, and relative position during bonding is from left to right in turn to the distance that moves down 8mm.

Claims

1, the combined-type rubber spring used of a kind of feeder that resonates is characterized in that the square rubber block 3 through machine-shaping, with the square rubber piece 3 more than four layers and aluminium sheet 2 at interval and have that the upper and lower steel plate base plate 1 of mounting hole is folded mutually to form through bonding.

2, rubber spring according to claim 1 is characterized in that: described square rubber block 3, when folding bonding mutually, its relative position is from left to right in turn to the distance that moves down 8mm.

3, rubber spring according to claim 1 is characterized in that: described square rubber block 3 is two groups of combinations, also can be one group, one and Ban, many group combinations.
