Problems solved by technology

The mold processing is complicated, the processing cycle is long, and the avoidance does not necessarily meet the design requirements, which brings great risks to product realization and quality control
Especially when pressing the slope, after the contact between the cage and the opening of the slope pressing die, the contour of the cage is deformed, and 100% of the contour exceeds the technical requirements and is scrapped

specific Embodiment approach 1

[0037] Such as Figure 1 to Figure 5 As shown, this specific embodiment provides a production device for stamping cage 4 of angular contact bearings, including a blanking stretching bottom cutting die, a punching and slope pressing die, a car edge device and a surface treatment device arranged in sequence along the feeding direction, The blanking stretching bottom cutting die is used for blanking, stretching and bottom cutting of the sheet metal, the punching and slope pressing die is used for punching and slope pressing of the sheet material, and the side device is used for the cage made of the sheet material 4 Carry out edge treatment, and the surface treatment device is used to carry out surface treatment on the cage 4; the blanking stretching bottom cutting die includes a mold base, a lower mold and an upper mold, and the lower mold is installed on the mold base, and the mold base adopts a structure of four guide columns 8. The upper mold is located above the lower mold an...

specific Embodiment approach 2

[0038] This specific embodiment provides a production method for angular contact bearing stamping cage 4, including the following steps:

[0039] Step 1: Use the blanking stretching bottom cutting die to perform blanking stretching bottom cutting on the pre-processed plate, and the blanking stretching bottom cutting action is all completed by the blanking stretching bottom cutting die; the original The three processes (cutting, stretching, and bottom cutting) are combined into one process, which can be completed on one mold, which improves precision, reduces manual operations, and greatly reduces labor costs and material costs.

[0040] Step 2: Use the punching and slope molding die to carry out the punching and slope molding, and the cage 4 is formed; the punching and slope pressing action is completed on one punch and slope pressure mold, the product consistency is obviously improved, and the mold structure is easy to assemble and disassemble, which has a relatively high perf...

Abstract

The invention provides a production method and a production device for an angular contact bearing stamping retainer, relates to the technical field of bearing manufacturing, and adopts the scheme that the production device comprises a blanking stretching bottom cutting die, a punching slope pressing die, an edge turning device and a surface treatment device which are sequentially arranged in the feeding direction; the production method mainly comprises the following steps: firstly, carrying out blanking, stretching and bottom cutting on a pre-processed plate by using the blanking, stretching and bottom cutting die, carrying out punching and slope pressing by using the punching and slope pressing die, forming the retainer, and then carrying out edge turning and surface treatment. The machining stability of the contact bearing retainer is improved, large-scale automatic production is achieved, economic benefits are created, meanwhile, labor cost, material cost and equipment cost are reduced, product competitiveness and profit are improved, and good application and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of bearing manufacturing, in particular to a production method and a production device for an angular contact bearing stamped cage. Background technique [0002] With the rapid development of science and technology, high-speed precision equipment is being developed and used more and more. Angular contact ball bearings are widely used in industrial pumps, industrial gearboxes, compressors, industrial motors and generators, trucks, trailers and Bus, metallurgy and other industries. However, the traditional angular contact bearing steel cage has complex processing technology, long processing cycle, complex mold processing, high manufacturing cost and unstable production quality. Therefore, its processing technology urgently needs to be optimized and innovated to improve the quality and stability of the cage to meet the company's development and market demand. [0003] The traditional processing route is: bla...
