Description

Technical Field

[0001] The invention relates to the technical field of rolling steel ball installation, and in particular to a rolling steel ball installation process method based on metal hot and cold deformation. Background Art

[0002] Rolling is a pressure finishing process that uses the cold plasticity of metal at room temperature and applies a certain amount of pressure to the workpiece surface using a rolling tool to cause the surface metal of the workpiece to flow plastically and fill into the original residual concave troughs, thereby reducing the surface roughness of the workpiece. Due to the plastic deformation of the rolled surface metal, the surface structure is cold hardened and the grains are refined, forming a dense fiber shape, and a residual stress layer is formed, the hardness and strength are improved, thereby improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a non-cutting plastic processing method.

[0003] At present, hardened steel balls need to be installed in rolling equipment. Since the steel balls are relatively small, the gap between the grooves where they need to be installed is also very small, and the installation accuracy requirements are also relatively high. There is currently no automatic steel ball installation device, and they are generally installed manually, which results in very high labor intensity, reduces assembly efficiency, and is very easy to miss.

[0037] A rolling steel ball installation process method based on metal hot and cold deformation, the hydraulic station 13, oil circuit 14, oil distribution valve 15, hydraulic cylinder 1, hydraulic cylinder bracket 2 belong to the power system, and the hydraulic cylinder 1 is fixed to the upper part of the tank bracket 5 through the hydraulic cylinder bracket 2. The air source 9, the air distribution valve 10, the air circuit 11, the circulating cooling tank 19, the cooling gas air inlet joint 18, and the cooling gas exhaust joint 21 belong to the circulating cooling system, the cooling gas air inlet joint 18 is arranged on the side wall of the circulating cooling tank 19 near the bottom 1 / 4 position, and the cooling gas exhaust joint 21 is arranged on the side wall of the circulating cooling tank 19 near the top 1 / 4 position; the inner wall of the circulating cooling tank 19 is arranged with a spiral cooling flow channel 19-4. The negative pressure fan 12, the air circuit 11, the rotary negative pressure suction device 4, and the negative pressure suction port joint 20 belong to the negative pressure suction system, and the rotary negative pressure suction device 4 is connected and fixed with the gland 19-2 on the top of the circulating cooling tank 19 by gland bolts 19-1.

[0038] A ball socket is arranged at the end of the push rod head 4-3 of the rotary negative pressure suction device 4. The size of the ball socket is consistent with the size of the rolled steel ball 4-6, and the center line of the ball socket is 1mm higher than the end face of the push rod head.

[0039] The steel ball inner screen ring 4-4 ​​is connected to the pinion 4-5 by three reinforcing ribs 4-7, the inner hole of the pinion and the push rod head are matched by (H8 / f7), and the bottom of the steel ball inner screen ring 4-4 ​​contacts the inner wall of the bottom vertebral body of the circulating cooling tank 19.

[0040] The distance between the inner wall of the steel ball outer sieve ring 19-6 and the outer wall of the steel ball inner sieve ring 4-4 ​​is the radius of the steel ball 4-6, and in this embodiment the distance is 5 mm; the lower plate rotating assembly 17 is arranged with at least 8 rolling head heating devices 17-1.

At this time, the rotating drive motor 7 drives the driving gear assembly 16 to perform low-speed rotational motion. The active pulley 16-3 drives the driven pulley 22-3 of the composite gear shaft 22 to rotate through the V-belt 6 under the drive gear 16-1. The pinion 22-1 coaxial with the driven pulley performs synchronous rotational motion.

When the ball-passing hole of the cylinder wall of the steel ball inner screen ring 4-4 ​​coincides with the ball-passing hole of the steel ball outer screen ring 19-6, the steel ball 4-6 enters the vertebral body at the bottom of the circulating cooling tank 19 through the two ball-passing holes, and the hydraulic cylinder 1 pushes the push rod head 4-3 of the rotating negative pressure suction device 4 to perform linear motion vertically downward.

[0044] Step ②: The rotating drive motor 7 drives the driving gear assembly 16 to rotate at a low speed. The driving gear assembly 16 drives the lower plate gear shaft 17-3 of the lower plate rotating assembly 17 to rotate through gear meshing, and the rolling head heating device 17-1 is turned to the bottom of the push rod head 4-3.

[0045] Step ③: The tool head is heated by the electric heating belt in the rolling head heating device 17-1 to complete thermal expansion treatment according to the expansion coefficient of the tool head material.

[0046] After the steps ①②③, the push rod head 4-3 pushes the steel ball 4-6 after the low temperature treatment into the tool head, and the installation of the steel ball 4-6 and the tool head is completed.

[0047] After completing steps ①②③, the lower plate rotating assembly 17 rotates the rolling head heating device 17-1 around the axis of the lower plate rotating assembly 17 to the next station after the gear meshing movement of the driving gear assembly 16, completing the automatic installation process of the steel ball and the rolling head.
