Abstract
The invention discloses a processing process of a screw for an ATM (Automatic Teller Machine). The processing process comprises the following steps: 1) drawing threads; 2) driving a head; 3) twisting screw teeth; 4) performing heat treatment; 5) performing surface treatment; and 6) performing inspection selection. The anti-theft screw produced by the processing process is good in quality, good in anti-theft property, less in damage possibility and long in service life.
Description
Technical field
The present invention relates to connection fastener areas, be specifically related to a kind of processing technology of ATM anti-theft screw.
Background technology
Such as the ATM agent of traditional communal facility needs to connect fastening parts multidigit hex(agonal)screw, this structure is owing to adopting hexagon bolt nut, very convenient when mounting and dismounting, important effect has all been played in every field, but owing to adopting hexagon bolt or nut, install, extracting tool is also very common, adaptability is extremely strong.But this convenience just, bring great unsafe factor also to above-mentioned facility, easily allow some lawless persons commit theft to ATM, cause economic loss.In addition, existing screw is due to the inappropriate operation in production process, and easily cause screw to damage, service life is short.
Summary of the invention
The object of the present invention is to provide that a kind of quality is good, anti-theft is good, be not easy to damage, the processing technology of the ATM anti-theft screw of long service life.
Technical scheme of the present invention is, a kind of processing technology of ATM anti-theft screw, comprises the steps:
1) line is taken out: the raw material bought are carried out annealing in process, put into stove and heat, slow heating is after 2-3 hour, be warming up to 400 DEG C, 750 DEG C are warming up in 3-4 hour afterwards, after insulation a period of time, stop heating, to come out of the stove after slow cooling air cooling, be placed on afterwards in hydrochloric acid solution and carry out pickling, take out after a period of time and wash, put into oxalic acid afterwards and carry out pickling again, take out after a period of time and put into warm water and wash, put into phosphoric acid afterwards again and carry out pickling, take out after a period of time and wash, finally with lubricator lubricate on surface, by wire drawing machine, raw material are evacuated to required wire diameter afterwards,
2) take the lead: by the raw material placing screws heading machine of processing being processed into the blank of screw, be processed into anti-dismounting structure at screw head, i.e. anti-theft screw semi-finished product;
3) threading: semi-finished product anti-theft screw is formed required screw thread through the system of rolling over or tapping;
4) heat treatment: advanced pretreatment, is heated to 850 DEG C in atmosphere by semi-finished product anti-theft screw and quenches, afterwards again 450 DEG C carry out high tempering, be cooled to normal temperature afterwards;
5) surface treatment: complete in the coating bath being about the zinc solution of 5500 DEG C by semi-finished product anti-theft screw parts submergence temperature, makes the iron-zinc alloy on semi-finished product anti-theft screw parts surface gradually become passivation zinc in product external surfaces;
6) inspection is selected: store delivery after the anti-theft screw that product appearance, size are all qualified is selected taking-up.
In a preferred embodiment of the present invention, described in take out be cooled to 500 DEG C in line step after to come out of the stove air cooling.
In a preferred embodiment of the present invention, described in take out hydrochloric acid in line step content be 35%.
Of the present invention is a kind of processing technology of ATM anti-theft screw, and the anti-theft screw quality that the present invention produces is good, anti-theft is good, be not easy to damage, long service life.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Of the present invention is a kind of processing technology of ATM anti-theft screw, comprises the steps:
