Forging process of small ring gear

Auto rear axle driven gear automation (small and medium ring parts) forging production line automation multi station presses, rolling ring machine automation connection car rear axle of the forging production field has been continuous development, many state-owned enterprises to technological innovation demand is relatively strong, private enterprises due to funding bottlenecks and orders of the continuation and other reasons, but also in the automatic production line. Co into the forging plant has visited Qijiang gear, radius of rotation, star horse car, Zibo gear, Sisivi bearing, bearing and other related enterprises, field research and technical communication, the use of foreign relatively mature automation program, for the domestic production of the product demand, provides the corresponding automation connection plan. Here is a simple, and hope that the parties to improve the guidance of experts. With the increase in the volume of truck sales and demand of small and medium ring parts, forging production of driven gear to keep up with the needs of customers. With the rapid development of the automobile industry, the automobile driven gear is the main product of the demand of the ring forming. At this stage, the automobile driven gear is more than the forging blank, but the gear is shaped ring, so there are many problems in the forging process, such as multiple forging, multiple heating, cutting allowance and so on. Due to the large amount of turning process, the waste of raw materials, the utilization ratio of the material and the cost of the enterprise, so the decline of the ring is an important way to reduce the cost of the ring. In the domestic ring molding focuses on two different forming process: A is ring rolling machine rolling expansion molding, ring rolling machine also known as reaming machine, ring rolling machine, ring a special forming method of; also useful hammer forging (trestle) forming. Compared with the rolling process and die forging process, improve material utilization rate of 2%~5%. In order to improve the utilization rate of raw materials, reduce the production cost and improve the competitiveness of the ring forging process. I communicate with each user unit and the calculation of the cost of ring forging, for all of us. Ring rolling process and hammer forging process comparison of rolling ring process than the process of die forging hammer and to save material, analysis from the design point of view, except the technology side skin part than small hammer forging process, the flying edge part of all save, as compared truck after the bridge basin gear forgings with two kinds of process, with ring rolling process to save 23% than die forging process of the material. Ring rolling process than die forging process, energy, if the use of 10t hammer forming the back of a truck bridge basin gear, the spring energy consumption is about 1100 yuan per ton, and the use of rolling ring forming process, the energy consumption is about 500 yuan (can save more than half. Ring rolling process with vertical and horizontal reaming machine ring rolling machine comparison small ring equipment purchase table (600mm * 50mm * 50mm ring for example) the purchase of equipment 2 Taiwan, 1 more coal hammer Taiwan, reclaimer 1, vertical reaming machine 1; three station press 1, 1 sets of electric furnace 2, robot, horizontal ring rolling machine 1; investment of approximately 100 million million 700 5 year depreciation 20 million / year 140 / million annual operating cost of 400 yuan / ton (artificial) 100 yuan / ton (Automation) / power coal consumption 400 yuan / ton to 400 yuan / ton weight (about 55.6kg 5-7mm 45.6kg (2-4mm) unilateral unilateral) product consuming fire before weight 55.6 * 1.03=57.3kg 45.6 * 1.01=46kg * 30 hours per month /6 day 200 tons 500 tons of PU material price of approximately 7.3 yuan /kg, 7.3 yuan /kg product quality difference of metallographic analysis of high price competitiveness of the weak and strong to sum up, I think the company's investment Capital equipment, expand production, the use of automated programs, will optimize the enterprise capacity, reduce the dependence on the mechanic, quality stability is also the same. At the same time, also hope that all aspects of expert guidance communication. Zhangqiu Weidong Forging Factory
