In the mechanical manufacturing and maintenance process, non-standard hexagon socket bolts or hexagon socket bolts that are not easy to purchase are often used. For this reason, we can design and manufacture a simple manual die and machine the hexagon socket bolts.
The middle guiding member is used for limiting the moving direction of the upper mold during operation, so that the upper mold can accurately rush into the reserved hole of the workpiece, thereby avoiding the upper mold being broken due to the non-perpendicularity of the upper and lower molds during the operation.
Considering that the manufacturing amount is not large, in order to reduce the production cost, the materials for the complete mold are all 45 steel, and the upper mold convex upper mold guide lower mold recess 1 and the lower mold concave gap generally leave 0.2~05mm, In order to avoid the damage of the upper mold, which may be caused by stress concentration, when the upper mold is manufactured, the hexagonal punch and the mold shank should have a rounded corner R transition. The hexagonal hole punched out in this way also facilitates the guiding of the hex wrench when inserted. The value of R is selected according to the specification of the bolt, generally between R0. 5~2mm. In order to ensure smooth stamping and avoid shearing, the end of the upper punch should be processed into the SR ball. After the upper die is finished, the punch part is quenched. The semi-finished part of the hardness bolt is firstly made according to the required hexagon socket bolt. According to the requirements of the drawings, the hexagonal bolts are machined to the inner hexagon socket.
The hole diameter d of the hexagonal bolt semi-finished product is made of hexagonal hex bolt. The head of the hexagonal bolt semi-finished head is heated and burned with a torch, put into the lower mold, and then the upper mold is inserted into the guide to hammer it. After that, the round bar is inserted from the lower die through the bottom hole end to punch the workpiece out. During the processing, the upper die should be cooled by water to avoid the hardness of the punch being annealed. ,simple. The production cost is low, and there is no need for stamping equipment. It is suitable for units with small production or no stamping equipment. (A) Finished parts (B) Semi-finished products (Zhang Min) (Continued from page 12) Shandong Agricultural Mechanization is moving forward in a down-to-earth manner In May of this year, when I was investigating cross-regional revenues in Henan, I encountered a machine that was not far from Shandong. The factory representative who went there to promote the wheat straw baler was also Shandong, introducing Shandong products with high quality and low price. Shandong agricultural machinery people in the province of agricultural machinery not only provide high-quality services for farmers in the province, but also serve the provinces with abundant agricultural machinery resources owned by the province. The world can be seen from a drop of water, which proves that Shandong's agricultural machinery is progressing in a solid way. After joining the WTO, the proximity advantage of the eastern coastal area of ​​the near-water platform will make labor-intensive agricultural products: vegetables, fruits, flowers and other key products of Shandong export, production and processing of facility agriculture, fruits, vegetables and flowers. Mechanical equipment will be a new bright spot for agricultural machinery in Shandong, and it has already and will continue to be at the forefront of the country. In the many adjustments of the agricultural machinery organization, Shandong is not shocked, flexible, retaining strength, entity, and real power. It is commendable to have the material foundation and organizational strength to be able to do practical things for the peasants.
Finally, we should once again thank Shandong Agricultural Machinery Department for its support for agricultural machinery policy and soft science research. When the former Rural Development Research Center of the State Council took the lead in drafting documents on agriculture and agricultural machinery, the deputy director Wu Shaowen and many others went to Shandong to investigate and hold seminars and draft research papers. Shandong agricultural machinery people made important contributions. The first national agricultural machinery technology economic symposium was held in Taian, Shandong Province in the late 1970s. The first provincial-level agricultural mechanization zoning in the country was completed in Shandong in the 1960s, and the results of past agricultural machinery soft science research. Accumulation, accumulation and accumulation, silently contributed to the national agricultural machinery technology economic research and policy research reserve. It is hoped that Shandong agricultural machinery in the 21st century will develop the soft science of agricultural machinery in Shandong and the whole country, democratize and scientificize the decision-making of agricultural machinery, and gradually achieve greater achievements for the mechanization of agriculture, and be diligent and intelligent but not rich enough. Chinese farmers do more real good things.
