Abstract

The present invention relates to a bearing manufacture equipment, particularly relates to a bearing capping machine. The capping machine includes a hydrostatic press, an air cylinder, an inner lane locater, an upper mould and a lower mould, wherein the upper mould connects with the screw rod of the hydrostatic press; the lower mould connects with the working table of the hydrostatic press; the inner lane locater locates above the lower mould in central position of the lower mould; the air cylinder locates below the lower mould and can pass the lower mould to contact with the inner lane locater and push-out the bearing work piece; the lower mould holds the outer lane of the bearing; the inner lane locater holds the inner lane of the bearing. The present invention characterized in that the shape and size of the intersecting surface of the upper and lower mould matches the outer lane of the bearing, and the upper and lower mould are provided with a T-shaped groove to adjust the central position of the upper and lower mould to align the upper and lower mould. By adopting above technical solution, the center locating of the upper and lower mould is accurate, operation is easy, hence capping speed and percent of pass are improved significantly.

Description

Bearing capper

Technical field

The present invention relates to the bearing manufacturing equipment, particularly a kind of bearing capper.

Background technique

Bearing needs to give bearing greasing, even fat in the reprocessing of making.For dustproof, generally need in the outer ring of both ends of the surface up and down at bearing of bearing, add a cover.

Existing crown capper generally all with the hydraulic system pressurization, cooperates suitable mould to realize sealing cover is pressed in the correct position of bearing.Existing mould generally is divided into mould up and down, but mould is because design is unreasonable about having now, and the mould location difficulty is easily located and forbidden up and down, causes the gland position unreasonable.And the matching die of the crown capper of 26 railway bearings does not also have at present.

Summary of the invention

The objective of the invention is to solve the gland problem of above-mentioned 26 railway bearings, provide a kind of and the bearing capper of the mould up and down of the easy adjusting location that 26 railway bearings are supporting.

Realize that the object of the invention technological scheme is: a kind of bearing capper, comprise hydraulic press, cylinder, the inner ring positioning work piece, upper die tooling and bed die, upper die tooling links to each other with the screw rod of hydraulic press, bed die links to each other with the table top of hydraulic press, the central authorities that the inner ring positioning work piece is positioned at bed die inside on the top, cylinder is positioned at the below of bed die, can pass bed die contacts with the inner ring positioning work piece to eject the bearing workpiece, bed die is held the outer ring of bearing, the inner ring positioning work piece is held the inner ring of bearing, it is characterized in that, on, the shape of cross section size of bed die cooperates with the outer ring of bearing, on, bed die is equipped with T type groove and is convenient to mould alignment up and down with the central position of mould about adjusting.

Further, be connected with nut between the screw rod of described upper die tooling and hydraulic press, described bed die is connected with screw with the hydraulic press table top.

Owing to adopted above-mentioned technical solution, solved the gland problem of 26 railway bearings fully, and because the mould up and down in this equipment has special locating slot, the centralized positioning of mould is accurate about making, easily operation, thus the speed and the up-to-standard rate of gland improved significantly.

Description of drawings

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

Fig. 2 is mould structure schematic representation about the bearing capper of the present invention.

Embodiment

The present invention is described in further detail below in conjunction with drawings and embodiments.

With reference to Fig. 1 and 2, a kind of bearing capper, comprise hydraulic press, cylinder 8, inner ring positioning work piece 6, upper die tooling 1 and bed die 5, upper die tooling 1 links to each other with the screw rod of hydraulic press 7, bed die 5 links to each other with the table top of hydraulic press, the central authorities that inner ring positioning work piece 6 is positioned at bed die 5 inside on the top, cylinder 8 is positioned at the below of bed die, can pass bed die 5 contacts with inner ring positioning work piece 6 to eject the bearing workpiece, bed die 5 is held the outer ring of bearing, inner ring positioning work piece 6 is held the inner ring of bearing, it is characterized in that, on, the shape of cross section size of bed die cooperates with the outer ring of bearing, on, bed die is equipped with T type groove 9 and is convenient to mould alignment up and down with the central position of mould about adjusting.

Be connected with nut between the screw rod of above-mentioned upper die tooling and hydraulic press, above-mentioned bed die is connected with screw with the hydraulic press table top.

Operating process:

With reference to figure 1, first sealing cover put into bed die, put bearing outer ring then, on this, put second sealing cover again.Sealing cover 4 is put into bed die 5, put into bearing 3 again, bearing outer ring is held by bed die 5.Bearing inner race is held by inner ring positioning work piece 6.Put sealing cover 2 above the bearing 3 again, enable switch, upper die tooling 1 position of exerting pressure downwards resets, and cylinder 8 actions eject whole work-piece.

Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technological schemes that are equal to also should belong to category of the present invention, should be limited by each claim.

Claims

1. bearing capper, comprise hydraulic press, cylinder, the inner ring positioning work piece, upper die tooling and bed die, upper die tooling links to each other with the screw rod of hydraulic press, bed die links to each other with the table top of hydraulic press, the central authorities that the inner ring positioning work piece is positioned at bed die inside on the top, cylinder is positioned at the below of bed die, can pass bed die contacts with the inner ring positioning work piece to eject the bearing workpiece, bed die is held the outer ring of bearing, the inner ring positioning work piece is held the inner ring of bearing, it is characterized in that, on, the shape of cross section size of bed die cooperates with the outer ring of bearing, on, bed die is equipped with T type groove and is convenient to mould alignment up and down with the central position of mould about adjusting.

2. bearing capper as claimed in claim 1 is characterized in that, is connected with nut between the screw rod of described upper die tooling and hydraulic press, and described bed die is connected with screw with the hydraulic press table top.
