Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is further described. Following examplesOnly for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
A manufacture method for excavator bucket teeth, comprises the following steps:
Step 1: due to from steel rolling mill's hot rolling bar out, and sectional area excursion is 4% left and right, and actual is irregular, the weight of only controlling its blank by cut lengths is inadequate, the blank that often obtained is the overweight or mistake of qualityGently, affect the forging of subsequent product, in order to ensure that product quality specifications is consistent, is placed in bar on automatic weighing device and claimsMeasure, and calculate quality and the volume of per unit length.
Step 2: bar heating, whole bar after weighing sent in heating furnace and carry out heating place by rod feederReason, comes out of the stove after being heated to 1200 DEG C-1300 DEG C, and the mode of heating of bar has three kinds: 1, intermediate frequency furnace heating; 2, natural gas addsHeat, 3, gas generator heating, in heating cost, intermediate frequency furnace is the highest, and natural gas is moderate, and gas generator is minimum, due to coal gasProducer is seriously polluted, therefore in the present embodiment, adopts heated by natural gas mode, adopts stepped heating in addition in the present embodimentStove heats.
Step 3: according to customer requirement and different heating furnaces, optionally carry out the step of descale, this stepSuddenly be by manipulator, the bar of coming out of the stove in heating furnace to be sent in descale machine oxide skin is removed.
Step 4: in order to enhance productivity and to ensure product quality, by the bar quilt under forging temperature after heatingSend into and in hot shears, carry out shearing blanking, and according to the quality of the per unit length calculating and volume automatically adjust shear longDegree, ensures that the small powder weight after shearing is even.
Step 5: forging molding, comprise blocking and finish forge, particularly, by manipulator, small powder is sent in Preform DieCarry out blocking processing, by manipulator, small powder after treatment blocking is sent into and in finish forge mould, carried out finish forge moulding.
Step 6: product appearance detects, and detects the half-finished geometric shape after finish forge, thereby sentence by laser detecting apparatusBe broken into the abrasion condition of mould, thereby can remind in time staff to change or keep in repair mould.
Step 7: polishing cleaning, by sander, half-finished overlap is removed, concrete, manipulator is delivered to workpieceOn alloy sander, polish, complete after polishing, manipulator is put into semi-finished product on the external mold that punching plays trade mark and is waited for punchingMachine work, adopts the mode of punching to play trade mark, and trade mark is difficult for erasing, without carrying out OEM, effective;
Step 8, quenches, and by through after polishing cleaning and leave the semi-finished product that forge preheating and send in automatic meshbeltfurnace, in stove, establishesHave 5 temperature controlled region, can meet the requirement of quenching technical, hardening heat is set to 890 DEG C, is incubated after 2 hours, drops into and is equipped with immediatelyThe quenching tank of quenching medium, asuforging has the following advantages: 1, asuforging can be before maintenance plasticity and toughnessPut, obviously improve intensity and hardness, forged harding is actual is the quench hot that has added deformation, therefore may obtain with high temperature and quenchThe tissue that fire is wanted to die, can all obtain dislocation plate martensite and eliminate twin crystal martensite; 2, save the energy, forged harding can be economized except largeThe heating energy source of part; 3, simplified supply and demand, reduced workpiece turnover, therefore can shorten the production cycle and solve man-hour; 4, improveWork situation, after forged harding hot-forging forming, drop into hardening media quench, forging heat is all taken away by hardening media, noDistribute again in workshop, therefore can reduce the impact of heat radiation on workshop and staff.
Step 9, tempering, workpiece enters automatic meshbeltfurnace, through samming, insulation, then drops in quenching tank and quenches, and is quenchingThe bottom of fire groove has been installed an automatic cat ladder workpiece has been risen to certain altitude automatic fall-back on the conveyer belt of tempering furnace, fromMoving sending in tempering furnace carried out tempering, and temperature is 200 DEG C-230 DEG C, is incubated the air cooling of coming out of the stove after 3 hours;
Step 10: detect packaging, it specifically comprises quality testing, surface finish, surface lacquer, packaging warehouse-in.
Beneficial effect of the present invention is: process automatic weighing processing before bar heating, calculating per unit length barQuality and volume, when hot shears is sheared then, can ensure that the quality of every small powder is even;
Bar, after heating, directly carries out hot shearing under forging temperature, cooling without carrying out, and saves time, and improves and producesEfficiency;
At residual forging heat temperature, quench, rationally utilize the waste heat forging, reduce energy waste, saved production cost;
By the detection of product appearance being judged to the degree of wear of mould, can remind in time work in process of productionPersonnel change or maintenance mould, thereby have ensured the quality of product.
The forging apparatus adopting in the present embodiment comprises working plate, on described working plate, is provided with groove, described recessedGroove can agree with die sleeve 1, and die sleeve 1 comprises the two parts that can be separated from each other, and two-part die sleeve 1 is close to a moulding separatelyMould 5, the interior slip of described shaping mould 5 is provided with guiding module 2, and the groove of shaping mould 5 belows is as molding space, described guiding module 2Inserted in described shaping mould 5 by hydraulic oil cylinder driving.
The embodiment of optimizing in the present embodiment is that described working plate below is provided with jack-up structure, described jack-up knotStructure comprises and ejects die sleeve oil cylinder 3, and it arranges upward, and the adapter sleeve that ejects die sleeve oil cylinder 3 is connected and is ejected with described die sleeve 1Described groove, two-part die sleeve 1 connects a radially demoulding oil jar 4 that can pull open towards avris separately.
The embodiment of optimizing in the present embodiment is, described working plate below comprises chute, and described chute is as passageThe working plate outside of leading, the workpiece after freely falling body separates is derived by chute
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the artSay, not departing under the prerequisite of the technology of the present invention principle, can also make some improvements and modifications, these improvements and modifications also shouldBe considered as protection scope of the present invention.
