Description
Technical field
The utility model relates to a kind of blade leading truck with casting die cast blade leading truck and is cast as pattern, belongs to the molded field of making of casting.
Background technology
Existing serial blade leading truck product is the vitals of adjustable spiral blade, plays guiding and gearing.The intensity and the plasticity of having relatively high expectations at aspect of performance, but also require to possess good low-temperature flexibility.Its preparation method: constitute and the mechanical performance requirement according to the product material chemical composition, this product often needs just can reach requirement through the forging molding production technology.The concrete production process of forging is: steel scrap raw material _ ingot casting _ forging molding _ part blank _ machined _ final products.Its weak point: the utilization rate of pressing the product blank material that the process of forging molding produces is very low, and the allowance of blank is big, and the process-cycle is long, and production cost is higher.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of blade leading truck and be cast as pattern with casting die cast blade leading truck.
Design: in order to realize above-mentioned purpose of design.The application changes the blade leading truck into blade leading truck foundry goods by forging under the prerequisite that satisfies the original performance of product fully, its production process changes steel scrap raw material _ casting _ part blank _ machined _ final products into.1, technological difficulties analysis: change casting into by forging molding, under same chemical composition and heat-treat condition, the mechanical property of foundry goods is lower than the forging, and particularly plasticity and toughness are more obvious.Because the original blank of forging is an ingot casting, through forging deformation and eliminated thick cast sturcture after the crystallization again, formed tiny recrystallized structure.Simultaneously because in the forging deformation process, eliminated defective such as the shrinkage cavity in the ingot casting, pore and improved the density of metal.And being segregated in the Forge Heating process in the ingot casting, because the diffusion of constituent element also has minimizing.Therefore the higher comprehensive mechanical performance of the easier acquisition of forging molding process by contrast.And this product wall thickness is thicker relatively, and in the casting solidification process, cooling velocity is lower, and very easily formative tissue dendritic arm spacing is excessive, and continuous tissue is poor, causes and organizes crystal grain thick.2, casting process scheme and measure: change casting into by forging molding, basic problem is exactly to solve the problem that comprehensive mechanical performance that casting brings descends, and the comprehensive mechanical performance of material depends primarily on the grain size of organizing of metal.Therefore to improve the comprehensive mechanical performance of steel-casting, just must make solidifying of foundry goods more help crystal grain thinning.According to the design feature and the performance requirement of paddle leading truck, the characteristics of bond material mainly design the production technology scheme of this foundry goods from two aspects of optimization that change thermal center distribution quickening casting solidification, material component.⑴ analyze casting manufacturability from the design feature of this foundry goods, temperature field characteristic distributions according to foundry goods, wherein square passes through the relative centrostigma of core position thermal center mutually with diameter shaft, it also is the highest temperature zone in the temperature field, this zone since the thermal center (-tre) in central core, the rising head root is on rectangle plane, and the feeding passage is not smooth, easily forms loose casting flaw.Therefore one side makes the thermal center (-tre) depart from the foundry goods body by setting up subsidy in technological design.⑵ because the size and the degree of supercooling of crystal grain have confidential relation, and degree of supercooling is big more, the crystal grain that obtains is thin more on the other hand.For the cooling velocity faster that obtains, set up the external chill Quench at local heat energy-saving position with from rising head heavy wall place far away.In order further to strengthen heat radiation, increase chill effect, adopting the Quench ability with the direct contact surface of molten steel surface is the chromite sand of 4 times of common silica sands, makes how much thermal centers reduce about 15%.The district sets up outlet pipe endways simultaneously, has both helped the eliminating of gas in the die cavity, and the part heat that gas discharge is simultaneously taken away provides help also for the heat radiation of die cavity.
Technical scheme: the blade leading truck is cast as pattern, it comprises blade leading truck shape casting mould, the foundry goods body is departed from thermal center (-tre) in the described blade leading truck shape casting mould, and is provided with the external chill Quench at the local heat energy-saving position of blade leading truck shape casting mould with from rising head heavy wall place far away.
The utility model is compared with the background skill, and the one, cause type to simplify production process by the forging molding rehandling, saved raw material, reduced production cost; The 2nd, by the peripheral hardware iron chill shock chilling, inside is optimized material component and adds microalloy element, thereby reaches the purpose of strengthening crystal grain thinning; The 4th, according to the blade leading truck foundry goods of the casting process scheme production that designs, product blank weight only is half of forging blank weight, and various raw-material costs also only be forging the cost of raw material 40%, one of luminescent material cost can reduce 60% at least, not only significantly reduced the process-cycle, and reduced production cost, improved production efficiency.
