Description

A kind of production technology of braking system part

Technical field

The invention belongs to auto parts technical field, more particularly, to a kind of production technology of braking system part.

Background technology

Anti-lock braking system, the braking function of the existing ordinary brake systems of ABS, and energy would generally be installed on Hyundai Motor Prevent wheel locked, make automobile remain to turn under on-position, ensure the brake direction steady of automobile, prevent to break away And sideslip, it is most advanced, brake apparatus that braking effect is optimal on current automobile.In order to lift its effect, pack alloy class Valve body receives substantial amounts of application in it.Need to set four axis holes on the valve body, therefore valve body is after die cast, it is also necessary to Four axis holes are processed successively, the time of consuming is longer, work efficiency underground.

The content of the invention

The present invention is in order to overcome the deficiencies of the prior art and provide a kind of production work of the high braking system part of work efficiency Skill.

To achieve these goals, the present invention uses following technical scheme：A kind of production technology of braking system part, bag Include following steps：

(1) raw material melt：Choose density and be more than 2.4g/cm³Aluminium block, melt in melting furnace to molten condition and be made Molten aluminum；Nitrogen is squeezed into molten aluminum by rotary getter afterwards, removes the gas in molten aluminum；

(2) die casting：Obtained molten aluminum in step (1) is injected into part mould, die casting is carried out by pressure casting machine Shaping, is made workpiece blank；Before die casting first releasing agent is coated on punch and mould；

(3) handle cutting is expected：The material handle of workpiece blank is cut off by cutting equipment；

(4) ball blast：The burr on workpiece blank surface is removed by file, afterwards using the stainless steel pellet of a diameter of 3mm Shot Blasting is carried out to workpiece blank, the ball blast time is 4-7min；

(5) rat holing：The inclined hole in left side is first drilled out on workpiece blank by inclined hole drilling equipment, adjusts workpiece hair afterwards Base position, then by inclined hole drilling equipment drilled out on workpiece blank right side inclined hole；

(6) Four-axis milling：Four using integrated Four-axis milling equipment to the workpiece blank after step (5) processing Axis hole carries out milling, cutting thread, drilling, polishing, the multinomial processing of deburring, and workpiece is made；

(7) it is passivated：Workpiece surface after step (6) processing is passivated；

(8) examine：Burr detection is carried out to the workpiece after step (7) is processed and surface passivation detects, after qualification to obtain the final product To finished workpart.

Workpiece is processed automatically by equipment in the present invention, die casting, ball blast, deburring, drilling and Four-axis milling Equipment is used, realizes the automation of whole production process, so that high degree improves work efficiency, is reduced artificial Input, reduces production cost；And in process, can be by integrated Four-axis milling equipment directly to four axis holes of workpiece Processing is carried out at the same time, original 1/4 has been tapered to so as to process and take, the time for shortening step occupancy of high degree, Improve work efficiency；And since four axis holes are without separate machined again, so that processing the equipment of axis hole can also be reduced, no Processing cost is reduced by only, also reduces occupancy of the equipment for the place of production that works.

Further, the burr is detected as manually observing workpiece surface, threaded hole, whether has burr in inclined hole, if It is jagged, burr is removed by serration file；Ensure that outer surface, axis hole of workpiece etc. jagged will not exist, prevent Workpiece causes scratch after using to ABS system to other parts.

Further, the surface passivation is detected as carrying out workpiece using salt spray test the detection of 72h；Ensure workpiece table Face has good anti-corrosion effect, and service life is longer.

Further, the releasing agent by lubricant and mould release with 1:The ratio of 90-120 is mixed to get；Lubricity is good, Effectively prevent workpiece from being adhered to punch or mould, workpiece stripping operation after die cast is more easy.

Further, the integrated Four-axis milling equipment includes fixture fixed station, for driving fixture to fixed station The actuator and processing knife group of rotation, after the position of workpiece blank is fixed by fixture fixed station, using processing knife Group is automatically processed workpiece blank；After workpiece is fixed by fixture fixed station, by processing knife group to workpiece Automation processing is carried out, easy to operate, work efficiency is high；Pass through the rotation of fixture fixed station, you can by the not coaxial of workpiece Hole is rotated to the position for the group processing of processing knife, so as to can be achieved to add four axis holes of workpiece by the operation of an equipment Work, the processing that shortens of high degree take, and reduce manufacturing procedure.

Further, the drive that the processing knife group is rotated including the turntable above fixture fixed station, driving disc Moving part and interval are arranged on 21 cutter heads on turntable；By the rotation of turntable, drive the cutter head on diverse location to rotate and be placed in work The position of part contact, is processed workpiece；Most of function of 21 cutter heads is different, is rotated by turntable, is realized not Same cutter head is processed workpiece, so as to can just be directly realized by a variety of processing to workpiece, processing effect by an equipment Rate obtains the raising of high degree；And cutter head is replaced by way of turntable rotation, replacement speed is fast, further increases workpiece The speed of processing, improves work efficiency.

In conclusion the present invention has the following advantages：Automation mechanized operation, work efficiency is high, and production cost is low；The four of workpiece A axis hole is carried out at the same time processing, and the taking when shortening processing of high degree, further improves work efficiency.
