Problems solved by technology

[0002] The existing universal joint outer ball cage generally needs to be processed and cut, and the cutting process is to flatten the mouth of the nut after the nut is installed, and the flat part is stuck in the groove to prevent the nut from retreating. , so that the process route becomes longer and the process cost is increased. On the other hand, the processing time is greatly increased, thereby reducing the processing efficiency; The spherical accuracy of the outer ball cage of the universal joint is relatively low, so its running accuracy is poor, which affects its service life and use effect. At the same time, the material has no self-lubricating performance, and it is easy to heat, soften and wear quickly under poor lubrication conditions. Failure, so it is necessary to improve the hardness, strength, lubricity and wear resistance of the material

Embodiment 2

[0045] A processing technology for an outer ball cage of a universal joint, comprising the following steps:

[0046] Step 1: Carry out bar blanking according to the external dimensions of the universal joint outer ball cage. The bar is made of Fe: 54% to 68%, Cr: 12% to 15%, Ni: 11% to 12%, and the balance impurities, prefabricated mixed matrix;

[0047] Step 2: The bar is drawn and hot forged by a forging die to produce a universal joint outer ball cage blank, while drawing and hot forging, adding C: 11.2% to 13.5%, Si: 1.4% to 1.8%, Mn: 0.1% to 0.5%, S: ≤0.015% powder; drawing and hot forging temperatures are controlled at 810°C to 830°C, and air-cooled to room temperature at the same time, so that the hardness reaches HRC55 and the tensile strength reaches 780MPa.

[0048] Step 3: Clamp the left end of the blank through the chuck, use a CNC lathe to rough the outer diameter and drill a hole at the center of the right end face of the external thread section 4;

Abstract

The invention relates to a universal joint outer ball cage and a machining process. The universal joint outer ball cage mainly comprises a bell jar section, a first transition section, a second transition section, an external thread section, a spline section and a cylindrical section, a center hole is formed in the center of the right side face of the external thread section, and six rectangular grooves are evenly distributed in the cylindrical surface in the circumferential direction. The material of the outer ball cage comprises the following components including 54%-60% of Fe, 12%-15% of Cr, 11%-12% of Ni, 11.2%-13.5% of C, 1.4%-1.8% of Si, 0.1%-0.5% of Mn, less than or equal to 0.015% of S and the balance impurities; a blank of the outer ball cage is prepared by adding C, Si, Mn and Spowder on a mixed matrix prefabricated by Fe, C and N during drawing and hot forging. The universal joint outer ball cage is simple in structure, large in hardness and high in strength and has self-lubricating performance and abrasion resistance, the machining precision of the spherical surface is greatly improved through a forming mill, the operation precision of the universal joint outer ball cage is improved, and the service life of the universal joint outer ball cage is greatly prolonged through the blank drawing forging forming technology and heat treatment.
