Description
Technical field:
The present invention relates to metallurgical flow control device fabrication manufacture field, particularly a kind of shaping, the Design of Heat Treatment Process sliding for slide gate mechanism carry out the method for processing and optimizing of knowing clearly.
Background technology:
Because slide gate mechanism slide rail existing environment for use temperature is higher, easily deform, old processing molding method can not meet the service condition of marketing users, and with regard to current processing status, material selects comparatively generality, popular, process is comparatively loaded down with trivial details, and Technology for Heating Processing effect is not good yet, result in production cost higher, utilization rate of equipment and installations is lower, the shortcoming that the onsite application life-span is lower.
Summary of the invention:
The object of the invention is to design a kind of processing molding method using the slide gate mechanism slide rail that material is simple, procedure of processing is simple, thermal effectiveness is good and cost is low.
Technical scheme of the present invention is, a kind of processing molding method of slide gate mechanism slide rail, is characterized in that: (1), by purchased raw material 4CrMoV1Si round steel, according to instructions for use, sawing becomes blank; (2) blank processed being put into chamber type electric resistance furnace heats to 750 DEG C, forging equipment pressure is arranged to 1000t, then take out round steel, with pneumatic hammer from one end to the other end, progressively forge, after round steel temperature is down to 600 DEG C, be reentered in chamber type electric resistance furnace and heat up, and then last process repeatedly, till square steel raw material being forged into 20mm × 30mm, guarantee that every limit is not less than the allowance of 2mm, wait for next step manufacturing procedure; (3) now the square steel blank forged is processed, first planer is utilized to process four limits, square steel blank is processed into the blank of 17mm × 27mm, and then according to its appearance and size of figure paper conversion, on slide rail, plane must retain the fine grinding surplus of 0.3mm ~ 0.5mm as requested, last according to drawing requirement position shape, blank has spudded in screwed hole; (4) blank after step (3) process being put into chamber type electric resistance furnace heats to 880 DEG C, workpiece come out of the stove after precooling be about 2-3 minute, treat workpiece corner angle blackout everywhere, outer surface is pale red, quench again, after process, hardness reaches HRC ≈ 42 ~ 45, completes processing, waits for next step manufacturing procedure; (5) workpiece after heat treatment is carried out to the inspection of appearance and size, deflection, heat treatment hardness, do not meet screening out of technological requirement, qualified workpiece enters next procedure; (6) according to processing technology requirement, carry out fine grinding to plane on workpiece, final size is guaranteed to meet drawing 16
+ 0.1mm requirement, placement after completing, waits for next step manufacturing procedure; (7) utilize demagnetizer, the slide rail after fine grinding is carried out demagnetization process; (8) utilize gas nitriding chemical treatments, the workpiece after step (7) processing is processed, completes rear surface hardness HRC ≈ 50 ~ 53; (9) polish to the burr of workpiece, the workpiece of having polished finally will be tested to the hardness after key dimension and nitriding, completes whole processing.
After present invention optimizes material, processing technology, Technology for Heating Processing, compare with existing track, life-span is beyond 3.5 times, slide rail is changed online by ladle, change under the line of whole realization, greatly reduce the labour intensity of operative employee, and fittings consumption cost, from processing technology, owing to have employed Forging Technology, from raw material, just reduce cost, in process, have employed numerical control device in addition more, not only increase production efficiency, a part of labour also saved, also reduces a part of cost.
Detailed description of the invention:
Describe embodiment in detail,
By the understanding to marketing users instructions for use, and the continuous test to multiple slide rail material, the material of slide gate mechanism slide rail is decided to be 4CrMoV1Si steel the most at last, is used for instead of 45# or 40Cr comparatively generally used at present.Because 4CrMoV1Si steel contains carbon and the vanadium of high level, wearability is good, and has good heat resistance, has good intensity, hardness and higher wearability when higher temperature, and after heat treatment, effect can be more obvious.
The application also by the optimization to processing and heat treatment process, ensure that the accuracy of slide rail dimensional accuracy, and reduces processing cost, and its service life of improving, main flow is as follows:
A blanking: utilize sawing machine, by purchased raw material 4CrMoV1Si round steel, according to drawing requirement, sawing becomes the blank of Ф 30 × 170mm specification;
B forges: the round steel of Ф 30 × 170mm is put into chamber type electric resistance furnace and heat to 750 DEG C, forging equipment pressure is arranged to 1000t, then take out round steel, with pneumatic hammer from one end to the other end, progressively forge, when after near 600 DEG C of round steel temperature, be reentered in chamber type electric resistance furnace and heat up, then in last process repeatedly, till square steel raw material being forged into 20mm × 30mm, guarantee that every limit is not less than the allowance of 2mm, wait for next step manufacturing procedure;
C roughing the: now 20mm × 30mm square steel blank forged is processed, first planer is utilized to process four limits, 20mm × 30mm square steel blank is processed into the blank of 17mm × 27mm, then CNC milling machine is being utilized, according to figure paper conversion appearance and size, but require that on slide rail, plane must retain the fine grinding surplus of 0.3mm ~ 0.5mm, finally according to drawing requirement position shape, with the screwed hole of upright drill processing M12 dark 9;
D heat treatment: the integral quenching mode that heat treatment mode is taked processes, putting into chamber type electric resistance furnace heats to 880 DEG C, workpiece come out of the stove after precooling be about 2-3 minute, treat workpiece corner angle blackout everywhere, outer surface is pale red, then quenches, and after process, hardness reaches HRC ≈ 42 ~ 45, separately put after all completing, wait for next step manufacturing procedure;
E intermediate survey: the inspection workpiece after heat treatment being carried out appearance and size, deflection, heat treatment hardness, does not meet screening out of technological requirement, and qualified workpiece enters next procedure;
F finished plane: utilize numerically control grinder, according to processing technology requirement, carries out fine grinding to plane on workpiece, and final size is guaranteed to meet drawing 16
+ 0.1mm requirement, separately puts after completing, and waits for next step manufacturing procedure;
G demagnetizes process: because of after all multistage manufacturing processes, workpiece can exist with certain magnetic, and this can have influence on the surface carburization effect of workpiece, so will utilize demagnetizer, the slide rail after plain grinding is carried out demagnetization process;
H surface carburization process: utilize gas nitriding chemical treatments, not bad to processing, the workpiece meeting drawing requirement is processed, and completes rear surface hardness HRC ≈ 50 ~ 53;
I removing surface and final inspection: after workpiece completes surface carburization process, need pincers worker to utilize shaping file, to the conscientious polishing of the burr of workpiece, guarantees workpiece presentation quality; The workpiece of having polished finally will be tested to the hardness after key dimension and nitriding, warehousing after passing.
