Problems solved by technology

In addition, the ball 12 itself has no power to rotate itself, but is driven by the lathe spindle and the surface of the rolled piece to rotate passively. Therefore, the wear of the ball 12 is serious and uneven. In this way, the precision and smoothness of the rolled part cannot be accurate. control

Embodiment 1

[0032] Such as figure 2 As shown, the present embodiment carries out finishing rolling and strengthening the surface of the workpiece through the following device. The device includes: a housing 5 and a pressure head 1 with a spherical working part arranged in sequence therein, a transmission shaft 3, a double-row radial bearing 8, clutch 6 and motor 7.

[0033] The pressure head is fixed in the center hole of the transmission shaft 3 by the screw 2, and the transmission shaft 3 is supported and fixed by the double-row radial bearing 8, and the bearing 8 is fixed in the housing 5, and the housing 5 is installed in the metal processing equipment superior. Nut 4 is screwed on housing 5 left ends, and its degree of tightness can adjust bearing 8 positions. The transmission shaft 3 is connected with the clutch 6 connected with the electric motor 7 .

[0034] The above-mentioned device is then installed on metal processing equipment, such as a lathe adapted to the workpiece to ...

Embodiment 2

[0044] The chain rollers are finished and strengthened.

[0045] The roller part diagram of this embodiment is shown in Figure 6 . The material is 20 steel. After the roller is cold extruded and punched, it is installed on the main shaft of the instrument lathe and fixed with a clamp. Will figure 2 The rolling flattening unit shown is mounted on a lathe carriage. After the lathe is started, turn on the rolling and flattening device again, so that the pressure head gradually touches the cylindrical surface of the left end of the roller, close the clutch, and the rolling can be carried out. v=26m / min at h s = Under the condition of 85μM, the corresponding feeding amount S 0 shown in Figure 4 . In order to ensure the maximum microhardness value of the surface layer, the rolling feed is about S 0 =0.08mm / rpm, at this time the surface microhardness H μ is 5000, and the surface roughness of the workpiece is R a = 0.08 to 0.12 μm. The process of fine turning and grindin...

Abstract

The invention provides a surface strengthening treatment technology and a surface strengthening treatment device for actively and rotatablely rolling and planishing the head of a roll compactor aiming at the surfaces of the plastically-deformed parts, belonging to the technical field of the manufacture of machinery parts. The technology comprises the step of rotatablely planishing by a rotated compactor head by the means of offsetting the axis of a part to be machined, so that the surface of the ball head of the compactor head can be evenly worn; the rotation means that a motor drives a driving shaft with the compactor head to forcefully and rotatablely move, the flatly-rolled compactor head supplementarily rotates around the axis of the flatly-rolled compactor head to start the planishing and strengthening work; and the offset means that the center of the compactor head offsets relative to the axis of the rolling strengthening parts. Through the surface strengthening treatment technology and the surface strengthening treatment device, the optimized combination among the surface machining fineness value, the surface-layer microhardness value and the residual stress value of the first compression can be guaranteed, therefore the technology and the device are suitable for the final remedying and the surface strengthening of the parts. By adopting the device, the wearing of the compactor head is reduced; and therefore, the technology and the device can be reasonably used for industrial enterprises which manufacture the important parts.

Description

technical field [0001] The invention relates to a process and a device in the technical field of mechanical parts manufacturing, in particular to a surface strengthening treatment process and device for a rolling head active rotating rolling finish rolling on the surface of a plastically deformed part. Background technique [0002] In the machine manufacturing industry, the failure of mechanical parts is mostly due to the inability of the material surface to withstand the harsh service conditions. The reasons for its failure can be roughly summarized as strength, wear and corrosion failure, and most of them occur on the surface or near the surface of the part. Therefore, improving the surface properties of materials plays a vital role in prolonging the service life of mechanical parts and realizing the potential of materials. As an independent subject, the surface strengthening technology that emerged as a result has developed rapidly and has become a new focus of the devel...
