The hot pressing mould has the functions of heating, pressure resistance, heat insulation and heat preservation to realize the automatic control of the temperature by the arrangement of a heating element, heat preserving material, heat insulating material and a cooling water system. The aligning and tempering device has the characteristics of simple production work procedure, convenient operation, energy saving, high producing efficiency, etc. The tempering effect and the aligning effect are obvious. The present invention is the ideal device for aligning and tempering the basal body of a large-size round saw blade and a metal flat board, and has wide popularizing and using value.
Description
The present invention relates to a kind of tempering heat treatment device of hardware, particularly be suitable for the hand alignment and tempering device for large saw-disc.
Large saw-disc must could use through Overheating Treatment before welding diamond joint piece.The saw bit matrix material therefor is 65Mn, the saw blade diameter 1600mm of general frequent use, and the thick 8mm of blank, big like this thin-wall part under the effect of internal stress and thermal stresses, certainly leads to bigger distortion during quenching.At present, the prior art of solution large saw-disc matrix distortion mainly contains: the saw bit matrix of quenching after strain is stacked together, after bolted, be placed in large-scale salt made from earth containing a comparatively high percentage of sodium chloride tempering stove or the air tempering furnace, slowly heat up tempering time 6～7 days, hammering shaping again after the taking-up; What have takes shaping-quenching-tempering-shaping-corase grind-finishing, and a saw bit matrix needs shaping 3-4 time from the blanking to work in-process; When having plenty of quenching, in the temperature of saw bit matrix during also at 300～200 ℃, be placed on and press on the press, carry out tempering-shaping-corase grind-finishing again, these methods all exist complex procedures, and the tempering shaping workload is big, and energy waste is also bigger, in heat-processed repeatedly, also want some clamp materials of loss.In addition, a kind of pressure with oil spout oil bath Quenching press of CN1068286-A patent disclosure quenched, and then the saw bit matrix after tens quenchings stacked is placed in the tempering stove, with screw block by lever to saw bit matrix press tempering.This method also is difficult to avoid saw bit matrix to produce distortion under the internal stress effect.Therefore, the heat treatment deformation of saw bit matrix is unresolved always a great problem.
The object of the invention is to solve the problem of large saw-disc matrix heat treatment deformation, and provides a kind of height of large saw-disc matrix smoothing to put energy-conservation tempering heat treatment device.
Key problem in technology of the present invention is to utilize four-column hydraulic press and tempering heat tracing to add pressing mold (abbreviation hot-die) formation tempering unit, under certain tempering temperature, both ends of the surface perpendicular to saw bit matrix are applied enough big power, and the realization saw bit matrix is once smoothed., can adjust as pressurizing device with four-column hydraulic press, can guarantee again that closing precision can satisfy to saw of the technical requirements of this matrix form and position tolerance to the size of the power that applies and the time that keep-ups pressure.Hot-die is the tempering equipment of heated parts, and hot-die promptly has heating function, and withstand voltage function is arranged again, and for this reason, the hot-die of this device adopts the refractory alloy cast iron materials to make.Hot-die is the upper and lower mould structure, and last hot-die and following hot-die are made of hot-plate, heat insulation back up pad, cooling plate and thermal insulation layer respectively, are separately fixed at heat-resisting bolt on the upper moving beam and worktable of hydropress.Hot-die also is provided with temperature-control heat couple near the middle part of heated parts under last hot-die reaches, and the realization temperature is controlled automatically.
With reference to the accompanying drawings the present invention is done further narration below.Fig. 1 is the structural representation of this device.The main composition parts are: four-column hydraulic press [1], upper moving beam [2], cooling plate [4], water-cooled tube [3], heat insulation back up pad [12], [13], hot-plate [9], asbestos plate [6], fire resistant heat preserving cotton [5], porcelain tube [7], heating unit [8], worktable [10], heat-resisting bolt [11], thermal insulation layer [14], asbestos mat [15], workpiece [16], temperature-control heat couple [17], water inlet sebific duct [18], water inlet manifold [19] etc.
Device of the present invention is made of four-column hydraulic press and hot-die, hot-die is the upper and lower mould structure, last hot-die and following hot-die are separately fixed on hydropress upper moving beam [2] and the worktable [10] by heat-resisting bolt [11], last hot-die and following hot-die are made of hot-plate [9], heat insulation back up pad [12], [13] and cooling plate [4] respectively, hot-plate evenly is provided with aperture in [9], porcelain tube [7] and heating unit [8] are installed, be provided with in the cooling plate [4] with hot-plate [9] on the corresponding water-cooled tube of aperture [3].Between hot-plate [9] and heat insulation back up pad [13], between heat insulation back up pad [12], [13], be equipped with asbestos plate [6] between heat insulation back up pad [12] and the cooling plate [4].Adopt vesicular structure in heat insulation back up pad [12], [13], fire resistant heat preserving cotton [5] is housed in its hole.Last hot-die and following hot-die thermal insulation layer [14] all is set all around, the bottom of last hot-die thermal insulation layer bonding with the asbestos mat [15] of heated parts stack pile.Water-cooled tube [3] that cooling plate on the hot-die [4] is provided with and outer water inlet sebific duct [18] and water inlet manifold [19] the formation recirculating cooling water system of hydropress.Going up the heating unit [8] that is provided with at hot-plate [9] links to each other with the temperature control cabinet.The middle part that contacts with heated parts [16] at last hot-die, following hot-die is provided with temperature-control heat couple, controls automatically by temperature controller realization temperature.
When the tempering of large saw-disc matrix, the workpiece [16] that quenches is placed on down on the hot-die, the primer fluid press, it is descending that hydraulic machine piston promotes upper moving beam [2], and the last hot-die that is fixed on the upper moving beam is descending together.Contact with workpiece [16] until hot-plate [9].Heated parts is incubated (400～500 ℃) 30～60 minutes under 150～300T pressure.Then, the primer fluid press will be gone up hot-die and mention, and take out workpiece [16].The large saw-disc matrix of tempered hot-pressing processing is smoothed, and its workpiece hardness satisfies the requirement of JC340-92 technological standard fully.
Alignment and tempering device for large saw-disc of the present invention, it is simple to have production process, easy to operate, characteristics such as save energy and production efficiency height, it is much that the saw bit matrix deflection that no matter quenches has, and can both reach tempering and smoothing simultaneously, and effect is very remarkable.This device is large saw-disc matrix and metal plate smoothing tempered new type ideal equipment, has popularizing value widely.
