Embodiment Construction
[0035] Example: such as Figure 1-2 As shown, the finished product of the integral passive disk has a total length of 67.7mm and a diameter of 54+0.3mm of the passive disk. The processing method of the integral passive disk specifically includes the following steps:
[0036] (1) blanking pre-heading billet: such as image 3 As shown, the round steel is blanked by a band sawing machine, and the round steel is cut into a blanking piece; the size of the blanking piece is φ20-0.2*88-0.4mm; the pre-heading blank is added to the high Frequency induction heating furnace with a heating temperature of 1000°C. The heated parts are pre-upset and formed by a 200T hydraulic press; The heading head is pressed down, and the material is divided to remove the scale generated during heating at the same time, and the blank is upset into a pre-upset blank with a boss on the upper end;
[0037] (2) pendulum rolling forming: such as Figure 4As shown, the pre-heading blank obtained in step (1) ...

Abstract
The invention discloses a processing method of an overall passive plate, which comprises the following steps: 1 blanking pre-upsetting adobe; 2 swinging and rolling for forming: processing the upset adobe obtained from step 1 for annealing, surface phosphatization and lubrication once in order respectively, then putting the pre-upsetting adobe in a swinging and rolling machine for swinging and rolling to form a cold pendulum grind member that has a plate-shaped upper end; 3 flange molding: processing the cold pendulum grind member obtained from step 1 for annealing, phosphatization and lubrication secondly in order, then performing flange molding; and 4 carburizing, galvanizing and circular grinding: processing the flange member obtained from step 3 for machining, gear squeezing, carburizing and heat treatment, galvanizing and circular grinding in order to form an overall passive plate workpiece. An overall passive plate is obtained through the technology; the workpiece intensity is improved; material and manpower are saved at the same time; labor and time are saved; and equipment occupy is saved.
Description
technical field [0001] The invention belongs to the technical field of precision forging, and in particular relates to a processing method of an integral passive disc. Background technique [0002] At present, most of the passive disks on the market are separated, and the connecting sleeve and the disk body are connected by welding. There are also a few parts that are integral, but those that are integral are all cut from large pieces of material. [0003] Because there are always defects in welding, and the coaxiality of the two products is not good. In the process of use, there will be breakage, and the machine shakes badly when it is working. At present, there are also a small number of passive disks on the market that are integral, but these integral passive disks are formed by cutting and processing large pieces of material, which wastes a lot of materials and occupies a relatively high amount of equipment. [0004] Therefore, it is necessary to develop a processing ...
