Abstract

A bearing body holder is made up of phenolic resin glass fibre, or SMC, BMC and DMC etc. composite materials through hot die pressing. Its advantages include high weight, high mechanical strength, uniform and accurate size, high surface finish quality and brightness, and low cost.

Description

Bearing holder and manufacture method thereof

The present invention relates to a kind of bearing holder that is used for bearing industry.The invention still further relates to the manufacture method of this bearing holder.

Metallic material such as present bearing holder multiselect steel plate copper, aluminium and cast iron are as the manufacturing raw material, but nonferrous materials costs an arm and a leg, and makes bearing holder processing technology complexity and manufacture cost height.In addition, inapplicable by the bearing holder Heavy Weight that metallic material is made in many occasions, limited its using scope.

Also has a kind of retainer that adopts phenolic resin class cloth pipe manufacturer on the market, the material price height of machine shaping, and through complicated mechanical processing technology comparatively such as cut-out, car, brill, decrease in yield involves great expense, and need leave the material surplus and process when machining, the material consumption is big, in machining,, destroyed the fibrous structure of inner original phenolic resin class stringing, reduced mechanical property owing to need the processing of various cutting formings.

The purpose of this invention is to provide a kind of not only in light weightly, and cost is low, the bearing holder that mechanical strength is high; For this reason, the present invention also provides a kind of method of making this retainer.

For achieving the above object, technological scheme of the present invention is that bearing holder adopts phenolic resin glass fibre or composite materials such as SMC, BMC, DMC.Adopt the manufacture method of hot press molding time processing moulding to process simultaneously.

After adopting technique scheme, the material of bearing holder is phenolic resin glass fibre or composite materials such as SMC, BMC, DMC, and these material weight are light, the intensity height.This material adopts the hot press molding time processing to be shaped to bearing holder, has eliminated the deficiency of machining process, no waste of material, and materials are economized, and processing technology is simplified greatly, has guaranteed the mechanical strength of bearing holder.Simultaneously, also guaranteed the morpheme of bearing holder, the conformity of size, the precision height, and make appearance degree of finish, the photometric brightness height of retainer, reduced cost of production, and yield rate is stable.

The present invention is further detailed explanation below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of bearing holder of the present invention;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the structural representation of the mould of the present invention's use.

Detailed process of the present invention is as follows:

One, technical specifications

Material: composite materials such as phenolic resin glass fibre or SMC, BMC, DMC

Briquetting pressure (Mpa): 80～100

Mold temperature (℃): 160 ± 5

Relative density: 1.75～1.95

Martin heat resistance (℃): 〉=200

Flexural strength (Mpa): 〉=180

Tensile strength (Mpa): 〉=158

Impact strength (kJ/m ²): 〉=80

Two, the manufacture method of bearing holder

1, hot pressing

2, molded

A, forming equipment: mould and hydraulic press

As shown in Figure 3, this mould by the middle cover 3 of fixedlying connected with soffit formwork 5 for the upper die plate 10 of one with last punch 11, plug 9, spring 2, locking cover 4, push rod 7, lower punch 8 and with push rod be that the supporting plate 6 of one is formed, lower punch 8 is between the column 5-1 of middle cover 3 and base plate 5, and push rod 7 is threaded with lower punch 8.

B, forming method:

In middle cover 3 addings suitable for reading, upper die plate 10 and last punch 11 are bearing holder 1 with composite material compression moulding downwards under the hydraulic press effect with composite materials such as phenolic resin glass fibre or SMC, BMC, DMC; Upper die plate 10 and last punch 11 when moving up, hydraulic press are pulled out, locking cover 4 moves down, plug 9 outwards ejects under the effect of spring 2, upwards release bearing holder 1 under the effect that supporting plate 6, push rod 7, lower punch 8 are taken blame for others under hydraulic press, bearing holder 1 is in middle cover 3 taking-ups suitable for reading; Supporting plate 6, push rod 7, lower punch 8 return to as Fig. 3 the position under the drive of hydraulic press, will lock cover 4 simultaneously and move up, and plug 9 is pushed locking, and then reinforced, the processing of second bearing holder 1 of beginning.

Claims

1, a kind of bearing holder is characterized in that: described retainer adopts phenolic resin glass fibre or composite materials such as SMC, BMC, DMC to make.

2, a kind of method of making the described bearing holder of claim 1 is characterized in that: this method is a hot press molding time processing moulding manufacture method.
