Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to sliders, and more particularly to blanks thereof, methods of manufacturing blanks and sliders, and systems using sliders.

Linear motion mechanical slides where precision linear motion is required, e.g. slider systems in printing equipment or machine tools, are known, but these are particularly prone to corrosion under their working environment, which reduces the accuracy of their operation. or affect the accuracy of operation of the machines controlling them, which often had to be replaced, which was uneconomical both in terms of replacement parts and lost machine time. Further, due to this tendency, there is a problem that this slider cannot be used in the food industry, which has strong hygiene requirements, or in the photographic industry, which requires high precision.

It is therefore an object of the invention to alleviate these drawbacks.

According to a first feature of the invention, a stainless steel blank for a slider with a bearing-interacting part is provided.

According to a second feature of the invention, there is provided a stainless steel blank for obtaining a slider having a body and a part that interacts with a bearing, the blank comprising hardenable stainless steel for forming said part and said body. The two steels are secured together to form a relatively non-hardenable stainless steel.

It may also have two parts, each consisting of a blank lateral edge.

The blank may consist of a curved substantially flat blank, and said portion may be a lateral edge thereof.

It may also have two parts, each consisting of a lateral edge of the blank.

The blank may consist of a toroidal or cylindrical blank, and said portion may be a radial flange extending around its outer circumference.

The flange may be oriented toward the center of the toroid or cylinder.

According to a third aspect of the invention, there is provided a stainless steel slider manufactured from a blank, said portion being hardened as described below, and at least a portion of the remaining portion being unhardened.

The portion may have a V-shaped taper.

The apex of the V-shape may be 90°.

The portion may have a hardness of 58 to 60 Rockwell C.

The remaining part, ie the body, may have means for fixing the slider to the back plate.X0 Said fixing means may be one or more through holes.

According to a fourth aspect of the invention, there is provided a method of manufacturing a stainless steel blank for a slider having bearing-interacting parts, one of which is hardenable and the other relatively non-hardenable. providing two stainless steel components, holding the two steels;
The adjacent edges are locally fused under vacuum, the fused metal is solidified, the blank is rough-finished to the required rough shape, and then the rough-finished blank is subjected to a quenching process under vacuum; provides a method of hardening only said portion.

The method may include removing the blank from a vacuum hardening furnace and then grinding the blank over substantially its entire surface area to provide a smooth finished slider.

According to a fifth aspect of the invention, there is provided a slider system comprising a stainless steel slider as described above or a stainless steel slider manufactured by the method as described above, and a plurality of bearings of a carriage, wherein the slider and the carriage move in relative reciprocating motion. The hair ring contacts the hardened edge or flange of the slider.

Embodiments of the present invention will be described below with reference to the drawings.

Referring to the drawings, the slider (1) is generally rectangular in shape, flat, and has opposing longitudinal edges or portions (2), with hardenability (2). The body, ie the remaining part (3), is made of relatively non-hardenable, ie soft, stainless steel. The entire slider (1) is precision ground and corrosion resistant. As shown in FIG. 2, the groove (2) is V-shaped, and in this embodiment the inclined surface (4) of the V is 90°. Precision grinding provides a parallelism of 0.013 mm per meter for the V-cut straightener (4), and also for straightness the slider (1) has a precision grinding of, for example, a stainless steel or aluminum back plate, i.e. the support plate (la). Similar tolerances can be obtained by precise attachment to the grinding surface. Suitable fastening means, such as screws or bolts, pass through the fastening means of the slider (1) in the form of through holes (6), by means of which the slider (1) is fixed to the support plate (la), and the through holes (6) can be easily formed by drilling the body (3). In this embodiment, four holes (6) are formed.

Edge (2) is made of stainless steel hardened to 580 well C. In this example,
Edge (2) stainless steel is 440C (AIS
I), which has a weight ratio of 0,

1.0Mn516~18Cr, 0.75Mo, 0.03
It has components of 0S, O, and Q40P. The soft stainless steel of the body, i.e. part (3), is of what is known as EN56A, which has a weight ratio of 0.12M.
axC, 1,0MaxSi, Mn1.00.1.0ON
i, 12-14Cr, 0.0458 and 0.04
It has 5P components.

The slider (1) shown in Figures 1 and 2 is used in a system (7) (Figure 3) in which four stainless steel angles (V) contact the bearing guide (8) and the slider ( The edge (2) of 1) passes through the figure 7 gap (9) of the contact hair ring, and the contact bearing consists of two bearing parts (10), (11), which when overlapped, pass through the figure 7 gap (9). ) is formed. The bearing (8) is sealed and lubricated for a high degree of protection.

The bearing (8) is supported by a concentric (12) or eccentric (13) stud, the eccentric stud (13) being mounted opposite the concentric stud (12) to adjust the free play of the system (7). We provide a simple and effective method to do so. Furthermore, when the outer circumference of the bearing part has a large diameter and a small diameter, the slider (
1) and the bearing (8) relative movement and interaction results in a constant wiping action.

The stainless steel slider (1) is manufactured from a blank, which itself is made of hardenable stainless steel for the edges (2) of the slider (1) and the slider (
Manufactured by using two strips of relatively non-hardenable stainless steel for the body of 1), i.e. the remaining part 3), and rough finishing their adjacent or contacting surfaces. .after that,
These surfaces are placed opposite each other and the steel is each clamped. The assembled steel is then placed in a vacuum chamber and an electron beam welding head is passed along the contact portion of the contact edge. The beam is l electron thick (1 electron thick) and 2
Adjacent edges of two pieces of steel are melted virtually instantly through their thickness, and the steel is effectively fused to provide a solidified monolithic composite structure. There is also very little heat dissipation, and the heat is quickly dissipated into a relatively large section of steel that does not receive the electron beam.

Therefore, no metal distortion occurs.

The composite structure is then removed from the vacuum chamber and roughened flat to form holes (6) and V-edges (4). The blank is then placed in a vacuum furnace and the edge (2
) is quenched. When a composite unit has inherent strength, no distortion occurs. When the edge (2) is hardened,
The blank is removed from the furnace, finished machined and precision ground throughout to form the slider (1). The slider can also be polished by this grinding, but additional polishing can also be applied if desired. The hardening process is applied only to the edges, i.e. the strips (2), and the hardened and polished edges do not corrode. The steel of the unhardened body, ie the remaining part (3), remains soft but does not corrode. Both stainless steels are of the martensitic variety.

The power required for the electron beam head is 6 kW and the blank can be 1200 mm long.

The invention described above can be modified. for example,
Only one edge (2) may be made of hardened stainless steel. Further, the slider (1) may not be straight, but may be curved, toroidal or cylindrical, and when the slider is toroidal or circular,
The part (2) to be hardened may be a flange. The blank may also be formed by using laser or plasma welding techniques.
