Basic production process of the hottest rolling be

The basic production process of rolling bearings

due to the different types, structural types, tolerance levels, technical requirements, materials and batches of rolling bearings, the basic production process is not completely the same

I. processing process of main parts of various bearings:

1. Processing process of ferrule: the processing of inner ring and outer ring of bearing varies according to different raw materials or blank forms, among which the processes before turning can be divided into the following three kinds, The whole processing process is: bar or tube material (some bars need to be forged, annealed and normalized) -- turning -- heat treatment -- grinding -- fine grinding or polishing -- final inspection of parts -- rust prevention -- warehousing---- (to be assembled and matched)

2. The processing of steel balls also varies according to the state of raw materials. The processes before cutting or polishing can be divided into the following three kinds, and the processes before heat treatment can be divided into the following two kinds. The whole processing process is: cold punching of rods or wires (some rods need to be punched with rings and annealed after cold punching to make traditional exquisite health products are bottles, cans and cans) -- cutting, rough grinding Soft grinding or smooth ball - heat treatment - hard grinding - fine grinding - fine grinding or grinding - final inspection grouping - rust prevention, packaging - warehousing (to be assembled and equipped)

3. the processing process of rollers varies according to the different raw materials. The processes before heat treatment can be divided into the following two kinds. The whole processing process is: rod car processing or wire rod cold heading, string ring belt and soft grinding - heat treatment - string soft points - rough grinding outer diameter - rough grinding end face - final grinding end face - fine grinding outer diameter - final grinding outer diameter - final inspection grouping - rust prevention Packaging ---- warehousing (to be assembled and matched)

4. Processing process of cage. The processing process of cage can be divided into two categories according to the design structure and raw materials:

(1) sheet metal → shearing → blanking → stamping forming → shaping and finishing → pickling or shot peening or cross polishing → final inspection → rust prevention, packaging → warehousing (to be assembled and matched)

(2) processing process of solid cage: processing of solid cage, It varies according to the raw materials or rough damage. Before turning, it can be divided into the following four blank types. The whole processing process is: bar stock, pipe stock, forgings, castings - turning inner diameter, outer diameter, end face, chamfering - Drilling (or broaching, boring) - Pickling - Final inspection - rust prevention, packaging - warehousing (to be matched)

II. Assembly process of rolling bearing:

rolling bearing parts such as inner ring, outer ring, rolling element and cage, etc. after passing the inspection, enter the assembly workshop for assembly. The process is as follows:

demagnetization and cleaning of parts → grouping and selection of inner and outer rolling (groove) dimensions → sleeve closing → check clearance → riveting cage → final inspection → demagnetization and cleaning → rust prevention, packaging of vulnerable parts 4: accessories → entering the finished product warehouse (packing and shipping)
