Description
Technical field
This method belongs to chain processing technique field, processes work more particularly, to a kind of tow chain for chain production
Skill.
Background technique
Chain is generally the chain link or annulation of metal, multi-purpose to make machine driving, traction；For the chain of obstacle traffic aisle
Shape object (such as in street, at river or harbor entrance), the mechanically chain of transmission.
A kind of chain and chain-plate material surface processing life is disclosed in the open file that presently disclosed number is CN203664377U
Producing line, the production line can make strip obtain clean and tidy surface effect；The waste hydrochloric acid contaminated soil of Pickling Descaling generation is prevented
And pollution of the acid mist to air, environment is protected, production cost is reduced.
But the device can not carry out effective bead to ring chain, between each other can when ring chain is tight
There is certain contact, and this contact surface is difficult to be hit by steel ball to arrive, and causes to be unable to get bead on the contact surface of chain,
So that the intensity between the contact surface of chain is lower, and influence the quality of production of chain.
Method content
This method for overcome the deficiencies in the prior art, provides a kind of pair of chain bead comprehensively and efficiently raw for chain
The tow chain processing technology of production.
To achieve the goals above, this method uses following technical scheme: a kind of tow chain processing for chain production
Technique, comprising the following steps: a. heat treatment: chain is placed in Equipment for Heating Processing, uses various assist mediums at high temperature,
It is heat-treated；B. it quenches: after chain is heated to certain temperature in Equipment for Heating Processing, held for some time, then according to wanting
Ask cooling in different media；C. it is tempered: being added by quenched chain in Equipment for Heating Processing with certain temperature
Heat, and it is cooling after held for some time；D. black: using macromolecule organic polymer principle, returned using in heat treatment process
Fiery waste heat film forming blacks；E. it shot-peening: by the shot spraying of shot blasting equipment certain diameter in piece surface, is formed uniform small
Pit；
Wherein, the shot blasting equipment includes work box, the cover board being flexibly connected with work box, multiple branch set on work box bottom
It is support foot, the first conveying roller for conveyor chain, the second conveying roller, third conveying roller and the 4th conveying roller, multiple for chain
The shot-peening module of bead, for controlling the first mobile connector of chain and the second connector, being respectively arranged on the first company
The first connection buckle and the second connection buckle on fitting and the second connector and for separating and collecting shot-peening when, fall to work box bottom
The scrap in portion and the collection device of steel ball, the shot-peening module are staggeredly defeated set on the first conveying roller, the second conveying roller, third respectively
Send the side of roller and the 4th conveying roller, the two sides of the work box be respectively provided with the first permanent opening passed through for chain and
The bottom of second permanent opening, first permanent opening and the second permanent opening is respectively equipped with rotatable roller；To chain
Before item carries out shot-peening, cover board is first opened, pulls the first connector, the first connector is passed through into the first permanent opening, first connects
Fitting successively passes through the first conveying roller, the second conveying roller, the gap between third conveying roller and the 4th conveying roller and shot-peening module,
First connector is finally pierced by from the second permanent opening, and then one end of chain is fixed on the first connection buckle, by chain
The other end be fixed on the second connection buckle, control the second connector winding get up, chain with the winding of the second connector and
Winding；Cover board is closed, the first connector is then controlled and starts to wind, when the first connector is wound, chain is will drive and starts to move；
When by the first conveying roller, the shot-peening module of the first conveying roller side starts, and carries out bead to the side of chain；By
When two conveying rollers, the shot-peening module of the second conveying roller side starts, and carries out bead to the side of chain；It is conveyed by third
When roller, the shot-peening module of third conveying roller side starts, and carries out bead to the side of chain;When by four conveying rollers,
The shot-peening module of 4th conveying roller side carries out bead to the other side of chain, when will to leave first defeated for the end of chain
When roller being sent to be moved at the second conveying roller, shot-peening module from service on the first conveying roller side, until whole chains remove
First permanent opening；Then chain is removed, the both ends of next chain to be peened are separately fixed at the first connection buckle and
On two connection buckles, the winding of the first connector is then controlled, chain is wound with the winding of the first connector, then controls second
Connector winding, to continue to carry out bead to chain；The clast generated when shot-peening and the steel ball fallen are by collecting dress
It sets and is handled；By the setting of above structure, so that chain can pass through the first conveying roller, the second conveying in work box
Torsion conveying between roller, third conveying roller and the 4th conveying roller, realizes the effect being separated from each other between the contact surface of chain, from
And shot blasting equipment is allowed more fully to carry out bead to chain, effectively raise the bead effect to chain
Fruit, at the same can be to chain shot-peening when the clast that generates be collected, avoid accumulation of the clast in work box and human body made
At injury.
