Abstract
The present invention discloses a kind of production technology of change spur gear of elevator door, using Shooting Technique, metal wheel hub is first prepared, to metal wheel hub cleaning by degreasing, pre-blast processing, then special adhesive is sprayed on the glue spraying face of wheel hub, dry, preheating, polyurethane material is molded on metal wheel hub again and forms tyre bead, it is followed by aging, bearing and central shaft is added, change spur gear of elevator door is finally made；The adhesive is using polyurethane resin as base-material, plasticizer, diluent, filler, coupling agent, stabilizer, anti-wear agent and antioxidant is added, in addition β (3,4 7-oxa-bicyclo[4.1.0) ethyl trimethoxy silane, bis- (trimethylsilane) esters of maleic acid, isooctyl thioglycolate antimonic salt, 5 hydroxyl 1 (4 hydroxyl, 3 methoxyphenyl) 30 diketone, zinc chromate and magnesia are also added into；Wheel hub and polyurethane tyre bead in the change spur gear of elevator door have larger adhesion strength, in the environment of compression at 200 kilograms after operation 2000 hours, still can also normal use, greatly meet the needs of people's production and living.
Description
Technical field
The present invention relates to elevator technology field, more particularly to a kind of production technology of change spur gear of elevator door.
Background technology
Currently, increasing with skyscraper, the use of elevator is more and more extensive, and elevator door is guided, carried with change gear
Elevator door moves；Traditional change gear includes metal wheel hub and the bearing on the inside of wheel hub, there is a strata outside metal wheel hub
Urethane tyre bead, currently, the production technology for preparing polyurethane roller is mainly two kinds of Shooting Technique and pouring technology, wherein being molded work
Skill is because its required mechanical equipment is at low cost, and injection molding process is simple, and production efficiency height is more favored by producer；But traditional injection moulding work
The bonding force difference for the tyre bead and wheel hub that skill is prepared, cannot meet using needs, or even tyre bead abjection occurs and change gear is caused to damage
Bad phenomenon so that elevator is not normally functioning, and leverages the life of high-rise buildings.
Invention content
In view of the deficiencies of the prior art, the present invention intends to provide a kind of production technology of change spur gear of elevator door,
The tyre bead and wheel hub for the change gear that the production technology is prepared using Shooting Technique and the production technology have preferable cohesive force, energy
Meet normal use.
To achieve the above object, the present invention provides following technical solutions：A kind of production technology of change spur gear of elevator door, including
Following step：
Step 1：Prepare metal wheel hub, the material selection aluminium alloy or 45# steel of metal wheel hub；
Step 2：The glue spraying face of metal wheel hub is cleaned, then carries out pre-blast feather plucking with quartz sand or iron sand grain
Processing；
Step 3：Adhesive is sprayed on the glue spraying face of wheel hub, then wheel hub is placed in humidity and is less than 60%, temperature 10-
2-4 hours in 40 DEG C of environment, the wheel hub after being dried；
Step 4：Wheel hub in step 3 is put in the preheating carried out at a temperature of 120-150 DEG C 4-12 hours, then by wheel hub
It is put into injection mold, and keeps the Jiao Kou of injection mold corresponding with the glue spraying face of wheel hub；
Step 5：Liquid polyurethane material is injected in injection mold, polyurethane material is made to be flowed into tire in injection mold
Loop-shaped is simultaneously bonded on metal wheel hub；
Step 6：Wheel hub is put into 8-16 hours in 70-110 DEG C of baking oven and carries out maturation process；
Step 7：Bearing and central shaft are packed on the inside of wheel hub, change spur gear of elevator door finished product is obtained；
Described adhesive includes following parts by weight composition：
Polyurethane resin：75 parts；
Plasticizer：3 parts；
Diluent：5 parts；
Filler：3 parts；
Coupling agent：2 parts；
Anti-wear agent：1 part；
Stabilizer：1.2 part；
Antioxidant：1 part；
2 parts of β-(3,4- 7-oxa-bicyclo[4.1.0s) ethyl trimethoxy silane；
Bis- 2 parts of (trimethylsilane) esters of maleic acid；
