Abstract
The invention relates to realization of production of a movable blade part for agricultural machinery by applying a fine blanking technology and a bulk forming technology, in particular to a process and a die for manufacturing the tooth form of a movable blade for agricultural machinery with a fine blanking and bulk forming method. The process comprises the following steps of: optimally designing the structure of a fine blanking die; determining the relation between a cutting edge clearance existing between a male die and a female die and the quality of a workpiece section, selecting process parameters of the tooth form of a bulk forming cutting edge, and the like, and belongs to the technical field of advanced metal processing and forming. By adopting a compound fine blanking, piercing and tooth form bulk forming process, the product performance is improved greatly, i.e., the intensity of a tooth form working part is enhanced, the service life is prolonged because the conventional machining is replaced, and metal fibers of a tooth form part are kept perfect and fine and are prevented from cutting off. The tooth crack phenomenon in the working period of the tooth form part of a product is reduced greatly, and sharp cutting is realized; meanwhile, blanking and piercing are completed at one time, so that the size accuracy of an assembly positioning hole is increased; the blade is arranged on a cutter holder, and is positioned accurately, uniformly and reliably; and the external dimensions of the blade are accurate, and have low roughness.
Description
Technical field:
The present invention relates to use the production of fine-edge blanking technology and bulk forming technology realization farm machinery cutting blade product; Be the technology that fine-edge blanking and bulk forming method are made agricultural machinery cutting blade profile of tooth; Comprise Optimal Structure Designing, punch-die cutting edge gap and the product cross section quality relation of fine-edge blanking mould, the selection of process parameters of bulk forming blade profile of tooth etc., belong to the metal advanced person and shape technical field.
Background technology:
Homemade blade of farm machine all is the process production of adopting machining, causes that the blade profile of tooth is whole, the metallic fiber structure is cut off, and intensity reduces, and shorten service life, and technological process is long, and production efficiency is low.In order to address the above problem, can adopt the fine-edge blanking technology to realize blanking and punching and profile of tooth volume die forming, not only improved production efficiency, shorten production procedure, and reduce the product cost.
Summary of the invention:
The present invention provides a kind of fine-edge blanking blanking and punching profile of tooth bulk forming combination process, has improved properties of product greatly, is mainly reflected in profile of tooth working portion intensity and improves; Increase service life; Reason is to replace traditional mechanical processing, and the parts of tooth metallic fiber is kept perfectly fine and closely woven, is not cut off.Product parts of tooth duration of work collapses the tooth phenomenon and significantly reduces, and cuts sharp; Simultaneously because blanking and punching is once accomplished, cause assembling and positioning hole dimension precision to improve, it is evenly reliable and the insert shape size is accurate that blade is installed on the knife bar accurate positioning, and roughness is also little.
Description of drawings:
Fig. 1 is a structure principle chart of the present invention.
The specific embodiment:
Art designs scheme of the present invention is following:
The farm machinery cutting blade is multiple tooth shape thin plate product, and material can be selected high-carbon steel for use, like the T9A cold-strip steel, for improving the processing technology of high-carbon steel material, can adopt and not have middle nodularization degeneration technique; Blade cutting edge (1) the bilateral symmetry some roads profiles of tooth (2) that distribute.Blade rear end is provided with installing hole (3), is used for the assembling of product.At first, in order to guarantee assembling and positioning hole dimension precision, adopt the fine-edge blanking blanking and punching once to accomplish, blade (4) installing and locating is accurately evenly reliable, and the insert shape size is accurate, and surface roughness is little.Then, the profile of tooth of blade cutting edge both sides adopts the bulk forming combination process, and the parts of tooth metallic fiber is kept perfectly fine and closely woven, is not cut off.Be mainly reflected in profile of tooth working portion intensity and improve, increase service life, and product parts of tooth duration of work collapses the tooth phenomenon and significantly reduces, and cuts sharply, can significantly improve properties of product.
