Description

Technical field

The invention relates to an ultra high speed moving telescope cover that completely covers an industrial machine and with the Be Movement of the movement device of the main spindle, the head of the industry strap, foot, pad, stand, piston, cylin ders, the ATC coating, etc. of the industrial machine slides.

State of the art

If previously metal materials such. B. cut by means of a cutting machine the splinters and splashes formed (hereinafter split ter) in the neighboring moving parts, such as the spindle heads etc., and led to disturbances of the smooth sliding movement and / or to Ab use of the movement device of the industrial machine, which consequently leads to egg deterioration in the performance of the industrial machine.

Especially when cutting metallic material through an Ult High speed machine tool is used for the purpose of removal from splinters and / or to cool heated material tel sprayed onto the workpiece on the machine tool, so that a sol ches coolant, if used in quantities, in the neighboring be moving parts, such as the spindle head of the industrial machine, and there Rust causes the In movement device to slide industrial machine deteriorates, which leads to a reduction in performance ability of the industrial machine.

As a countermeasure to these problems, the industrial machine, which an exposed moving device such as a spindle head, etc. usually has at least one coating over the machine and / or protected over its parts, these covers usually Bellows are made of fabric or vinyl material, but they are Materials problematic in terms of physical strength. Instead of These materials are used in some special industrial machines today NEN telescopic covers used, which alternately in one direction  slide and from stacked thin metallic part covers consist of stacking over the other covers in order slide.

The conventional telescopic cover, as shown in Fig. 1, z. B. more than one partial covers made of metal plates 2 a-e of square shape, which are stacked over the other partial cover, and is constructed such that each partial cover plate 2 a-e slides in the right and left directions, with a thin sheet 3 , made of a rubber material in one part, at the end of each partial cover 2 a-e are provided where the plate end touches the other plates 2 a-e. The Ma materials of the sheet 3 consist of felt, vinyl, etc. and rubber.

Furthermore, the telescopic cover 1 , as shown in FIG. 2, covers an industrial machine 5 , one end of the partial cover 2 a being fastened to the movement device 4 of the industrial machine 5 , and likewise to the other end of the partial cover 2 e to the fastening device 6 the industrial machine 5 is fastened, each partial cover 2-e alternately sliding in the right and left directions with the right and left movement of the movement device 4 of the industrial machine 5 .

Accordingly, the partial covers 2 a-e of the telescopic cover 1 together with a left movement of the movement device of the industrial machine 5 to the left, and the sheet 3 made of rubber slides to the left so that fragments and / or coolant are discharged. At closing, the partial covers 2 a-e of the telescopic cover 1 contract with the rightward movement of the movement device of the industrial machine 5 , and the sheet 3 made of rubber slides to the right, so that fragments and / or coolant are discharged, thereby causing penetration of these fragments and / or the coolant in the interior of Bewegungsvor direction 4 of the industrial machine 5 is prevented by splitting the partial cover plates 2 a-e.

Likewise, the above-mentioned telescopic covers (partial covers) usually made of steel plates (SF41 and / or PSG etc.), however they are in view of the heavy load on the telescopic covers problematic, the heavy load having increased frictional resistance  causes various problems related to sliding properties, durability, abrasion, abrasion resistance, phy sical strength, desired lightweight, etc. leads.

Likewise, the above telescopic cover is usually made of stainless steel Steel plates (SUS301H, SUS304H, SUS63, SUS631 etc.) manufactured. all However, these materials are widely used in relation to higher ones Cost, corrosion resistance, heat treatments of hardening and annealing hens etc. problematic.

Likewise, in the above-mentioned telescopic cover 1, the partial covers 2 a-e are independent of one another, in each case parts for themselves and not connected to one another. Therefore, the partial cover 2 b z. B. seen mechanically before that it is mainly moved by the partial cover 2 a. In this case, the respective partial covers 2 a-e do not slide simultaneously and with the same movement distances, but each partial cover 2 a-e moves unevenly from the easily movable cover, with some other covers remaining unmoved at first. As a result, the entire telescopic cover 1 does not slide smoothly and is also uncomfortable or uncomfortable to use due to the lack of a linear movement, the formation of disturbing noise, frequent failure, etc.

Furthermore, the rubber sheet 3 attached to the conventional telescopic cover 1 is so thick (3 to 10 mm) that the gaps between the individual cover plates tend to widen (10 to 20 mm). Dement speaking there are inevitable weak points, so that splinters and / or coolant get inside, both the shape of each cover plate 2 a-e and the telescopic cover 1 is larger and heavier and the sheet 3 is rubbed off so easily that a poorer sliding movement and lower durability, etc. is caused.

Likewise, the sheet 3 made of rubber, with which the above-mentioned conventional telescopic cover 1 is provided, is part of a flat bolt plate, the entire bottom surface of the sheet 3 being slid in contact with the entire surface of the partial covers 2 ae men will. However, it is due to the abrasive conditions and / or the worn blade 3 and the uneven surfaces of the respective Teilabde ckungen 2 a-e difficult to keep the entire bottom surface of the sheet 3 with the GESAM th surface of the partial covers 2 a-e in contact.

The bottom surface of the sheet 3 tends to stand with the surface of the individual partial covers 2 a-e, forming point contacts in partial contact, so that these point contacts lead to problems by forming gaps in the contact surface with the sheet 3 , whereby these gaps splinters and coolant get inside, which leads to a weak point while reducing the sealing and through-running properties. In particular in the case of the production of the individual partial covers 2 a-e in a round or oval shape and the attachment of the sheet 3 to a curved edge, point contact is brought about, which easily leads to a reduction in the sealing and flow properties.

Further, the sheet 3 is usually a-e mounted on the individual partial covers 2 a-e of the above-mentioned conventional telescopic cover 1 only at the edge of the respective partial covers. 2 Therefore, wide gaps are formed there at the points of the left and right edges and the rear edges of each partial cover 2 a-e, where no sheet 3 is attached and the penetration of splinters and coolant through these gaps is unavoidable.

In addition, the movement device of the covers is provided for the Main spindle, spindle head, foot, support, column, piston, cylinder, ATC cover, etc., in the previous industrial machines represents that it is not just one way back and forth, right and left, up and down moves, but also in two intersecting Because of how back and forth as well as left and right, left and right as well as up and off, etc., which moves the conventional covering materials, which are used for unidirectional movement when in use the movement in these crossed directions are matical.

Detailed description of the invention

In the following, for example, an industrial machine will be described which is provided with the ultra high speed moving telescope cover of the present invention. As shown in Fig. 3, the telescopic covers 1 are constructed from the metal foil partial covers (hereinafter called partial covers) 2 a-e, the partial covers 2 a-e of the telescopic cover 1 sliding approximately at the same surface level in the direction from left to right.

A change in the stacking order of the individual partial covers 2 a-e of the telescopic cover depending on the discharge direction of the splinters and / or the coolant and the direction of movement of the industrial machine is of course possible. For example, the partial cover 1 a can be placed at the lowest point, and the partial cover 2 a-e can be stacked over it.

Each telescopic cover 1 consists of several parts of the partial covers 2 ae, which are made of a metallic foil made of stainless steel with multiple layers and high strength and are made of a mixture of ferritic phase, martensitic phase and finely mixed texture with 17% Cr Include -2% Ni as main parts, which are 0.5-3 mm thick and stacked in a rectangular shape so that they are capable of sliding stacking and the physical strength and the frictional resistance were improved when using the telescopic covers.

As shapes of the partial covers 2 a-e of the telescopic covers 1 , in addition to the rectangular shape, square shapes, round shapes, oval shapes, lid shapes, roof shapes, box shapes etc. can be used. The number of partial covers can range from 3-30 parts, and the width is 5-100 cm and the length is 13-50 cm acceptable dimensions.

The above-mentioned width and length of the partial covers 2 a-e can each be different. For example, the partial cover 2 a of the cover 1 may be 5 cm longer than the partial cover 2 b, the partial cover 2 b may in turn be 5 cm longer than the partial cover 2 c. Furthermore, the cover part 2c may be 5 cm longer than d, the partial coverage. 2 So each cover length can be different.

The sliding parts at the edges of the partial covers 2 a-e are metal foil sheets 3 provided such that they slide by pressing the sliding surfaces on the other part covers.

As materials of the sheet 3 , steel or stainless steel with a carbon content of 0.03-0.1% and a chromium content of 10-20% (hereinafter referred to as stainless steel with a low carbon content and high chromium content) is used, these materials Present products from the latest developments with outstanding properties with regard to high strength (tensile strength 1200-2000 N / mm ² ) and are sold with the product names according to the NISSIN steels SUS631, NSSHT1770, NSSHT1960 and NSSHT2000.

Stainless steels with a low carbon content and high chromium content have a high hardness (wear resistance) as well as special properties with a low reduction in strength during welding. Therefore, these materials are used as compact, lightweight and highly reliable sheets 3 with the thickness of 0.01-0.03 mm.

As shown in Fig. 3, the blades 3 made of low carbon and high chromium stainless steel can be on the sliding parts of the partial covers 2 ad with a width of 0.5-3 cm, a corresponding length each partial cover, a thickness of 0.01-0.3 mm and a rectangular shape. As shown in Fig. 4, a plurality of sheets 3 with a rectangular shape and 0.5-3 cm wide, 1-5 cm long and 0.01-0.3 mm thick can also be on the entire surface of the sliding part of each partial cover be attached at a distance of 1-5 mm.

When several sheets 3 are attached, the number of sheets to be attached normally ranges from 2-8 pieces per 10 cm (on a partial cover), although this depends on the size of the partial covers 2 .

Further, in the Tele skopabdeckung 1, the linearity and lubricity of the telescopic cover 1 are improved by the attachment of the pantograph. 7 The fastening device of the pantograph 7 is, as shown in Fig. 7, for fastening the connecting nipple 9 of different lengths and is used in such a way, on the carrier board or the carrier plate or the support plate 10 , fixed to the lower side of the partial coverings 2 ad the telescopic cover 1 and in the cross points adjacent to the connecting nipple 11 of the connecting bolt 8 of the pantograph 7 to rotate. At the location of the carrier board 10 , a connection support or other fastening device can be provided.

Further, as shown in Fig. 6, between the two sets of the telescopic cover 1, the moving device 4 of the main spindle head, etc., of the industrial machine is fixed so that it is capable of sliding. The telescopic cover 1 , provided with metal foil sheets 3 and the Pantogra phen 7 , is attached to the holder 14 of the U-shape section at both edges of the manner that it is capable of sliding.

The operation of the telescopic cover 1 of the present invention will be explained with the help of FIG. 6 as follows. Together with the BEWE account the movement device 4 moves to the left after it has been slidingly to move below: While the partial covers 2 of the telescopic cover 1 to move a-e under contraction downward slide part covers 2 a-e of the other telescopic cover 1 by pulling downward. Subsequently, while the partial covers 2 a-e of the lateral telescopic panel 1 under contraction slide to the left, the slide coverings Teilab 2 a-e of the other lateral telescopic cover 1 by pulling to the left, and that approximately in the same flat plane.

Applies equally along the movement of the main spindle head 4 to the left: currency of the telescopic cover 1 rend the partial covers 2 a-e under contraction after sliding to the left, slide part covers 2 a-e of the other Teleskopab cover 1 by pulling to the left. Analog during sliding motion of the device 4 to the right: while the part of the cover 2 a-e of the cover 1 under Teleskopab off by sliding the right slide part covers 2 a-e of the other telescopic cover 1 under contraction to the right.

While the telescopic covers 1 , as already mentioned above, slide along the movement of the movement device 4 with extension and contraction (contraction), the other telescope covers 1 also slide with extension and contraction approximately in the same flat plane. In such a case, the pantograph 7 also slides under extension and contraction for improving the lubricity and linearity of the two telescopic covers 1, and simultaneously carry the sheets 3, which are mounted on the telescopic cover 1, and the telescopic cover 1 splitter and / or cooling agents and the like and prevent intrusion.

The carbon content of 0.03 to 0.1% in the low carbon and high chromium stainless steel used for the blades 3 prevents the reduction in strength caused by welding the blades 3 directly on the partial covers 2 . While a carbon content below 0.03% can improve the welding properties, it also causes an undesirable reduction in the hardness of the blades 3 , while a higher carbon content of the stainless steel above 0.1% directly reduces the strength when welding the blades 3 on the partial covers 2 .

Furthermore, a chromium content of 10 to 20% of the low carbon and high chromium stainless steel results in higher hardness (wear resistance), while a lower carbon content below half 10% cannot give the blades 3 an acceptable hardness. Furthermore, a higher chromium content above 20% can improve the hardness, but it also has disadvantages in terms of elasticity.

Also, a thickness in the range of 0.01 to 0.3 mm of the low carbon and high chromium stainless steel sheet used for the metal foil sheets 3 leads to high strength (tensile strength), elasticity, etc. In addition, a Excess loading of the movement device and the sliding parts of the telescopic cover by reducing the contact area and the frictional resistance of the sliding parts of the telescopic cover 1 with the resulting reduction in the driving force required for the telescopic cover 1 , min.

If the thickness of the low carbon and high chromium stainless steel sheet is less than 0.01 mm, an acceptable hardness and physical strength required for the sheets 3 cannot be obtained. Likewise, the production of thinner sheets 3 below 0.01 mm in thickness means higher costs and inconveniences in production. In addition, if the thickness of the low carbon, high chromium stainless steel sheet is more than 0.3 mm, this leads to unacceptable disadvantages in the elasticity and weight of the sheets.

The edge of the metal foil sheet 3 is welded onto the sliding parts at the edge of the partial covers 2 and the overhang of the cover part (0.05 to 1 mm) is used as the sheet. The sheet 3 can be in any shape provided that it has a flat surface and the upper end of the sheet 3 protrudes from the partial cover 2 . Likewise, spot welding or laser welding are preferred as the welding method for fixing one end of the sheet 3 to the partial cover 2 , but other welding methods can also be used.

In order to fix the sheet 3 on the partial cover 2 , fastening methods other than welding, as already mentioned above, can be used. For example, the attachment by means of adhesive to the sliding surface of the partial cover 2 and the edge of the sheet 3 and also the attachment by means of adhesive and rivets is possible in order to prevent the penetration of coolant. In addition, such an attachment is easier.

With regard to the attachment of the metal foil sheet 3 on the sliding parts of the partial cover 2 , the accuracy is improved when the sheet is formed in an L-shape or in the form of a mountain, so that the sheet 3 is reinforced and becomes more pressure-resistant as well as sealing and Pass-through properties vis-à-vis liquids and / or contaminants are significantly improved.

Stainless steel can be used as the material of the pantograph 7 . To improve the physical strength of the pantograph 7 , however, high tensile multi-layered stainless steel with a mixed texture, consisting of a soft ferritic phase, hard martensitic phase and fine grain structure with the main part consisting of 17% Cr and 2% Ni, can be used.

As a material for the connection nipple 9 of the pantograph 7 , the steel cannot rust. However, the use of stainless steel with grain boundary nitriding treatment has the following features: The surface of the connector nipple 9 is hardened to have superior lubricity and high physical strength, which can bear the excess weight that can be carried on the connector nipple 9 of the connecting bolt 8 of the pantograph 7 , and is not loosened by surface destruction, while the interior of the nipple 9 maintains the elasticity, since it is not hardened in the middle, so that the nipple 9 neither bends nor breaks. The flexibility and slidability of the pantograph 7 are thus improved while maintaining the stable and uniform operation even during long-term use.

In addition, the use of laminates of 2 to 10 pieces of stainless spring steel sheets of 0.1 to 3 mm in thickness in the connecting bolts 8 of the pantograph 7 increases the properties of the connecting bolt 8 with respect to its elasticity, rigidity, physical strength and also improves the Flexibility, which gives the pantograph 7 increased elasticity.

When used accordingly for the pantograph 7 of the telescopic cover 1 , the connecting bolt 8 , made from the laminated stainless spring steel sheet, is flexible and mutually flexible in order to withstand the high load, and does not bend and does not break. In this way, the elasticity, slidability, linearity of the pantograph is increased and the stable and uniform long-term function is also improved.

With regard to the attachment of the pantograph 7 to the telescopic cover 1 , as shown in FIG. 7, the connecting nipple 15 of the pantograph 7 is fastened to the partial covers 2 a-d of the telescopic cover 1 and above it the sliding nipple 19 of the pantograph 7 into the slot guide 17th the slit plate 16 is inserted in this way, which is fastened on the partial covers 2 a-d of the telescopic cover 1 , so that sliding is possible.

As shown in Fig. 8, the connecting bolts 8 are attached to the Teilabdeckun gene 2 a-g of the telescopic cover 1 , and the sliding connection nipple 9 of the pantograph 7 are also attached so that they slide into the slot of the shock-absorbing material 20 in a ring shape, as in Fig. 8 shows ge are capable, so that the shocks can be dampened during the retraction of the pantograph.

If with respect to the attachment of the pantograph 7 to the right-angled partial covers 2 a-g, which have the same width but a different length, the telescopic cover the partial covers 2 ag are completely retracted, the greater the differences in length, the greater the distances obtained individual covers are. These distances can be used for attaching the carrier board or the carrier plate or support plate 10 for inserting the connecting nipple 9 .

However, if the partial covers 2 a-g are completely retracted for fastening the pantograph 7 to the partial covers 2 a g with the same width and length of the telescopic cover 1, there are no gaps due to the same lengths. Therefore, as shown in Fig. 8, the pantograph 7 is fixed by providing the recesses 18 in different lengths at the end of the partial covers 2 a-g in the slots of these recesses, whereby the ultra high-speed telescopic cover 1 can be manufactured in a compact form.

In addition, if the pantograph mounted in the telescopic cover 1 is provided in parallels of 2 or more rows at intervals of 10 to 50 cm, improvements in the slidability and linearity of these telescopic covers can be achieved.

In particular, if the connecting bolt 8 is made of a multi-layer construction of high-strength stainless steel and lamellar structure, the connecting bolts 8 become more flexible and stabilize the pantograph 7 against the high load, and the slidability and linearity of the pantograph 7 are increased in such a way that stable and uniform functioning can be maintained even over a long period of time.

Moreover, when a lubricant between the sides of the laminated Ver connecting pin 8 is sprayed, the lubricant passes through its Kapil larwirkung inwardly into the entire side surfaces of each Verbin dung bolt 8, wherein the lubricant is impregnated not only the individual pages of the connecting pins 8, but wherein the Lubricant is equally dispensed onto the individual connecting bolts 8 and the connecting nipples 9 through the lubricant running out on the sides of each connecting bolt 8 . As a result, the slidability and linearity of the pantograph 7 is significantly improved, a stable and uniform function of the pantograph 7 is achieved and no abrasion around the connecting bolt 8 and the connecting nipple 9 and no noise or other trouble causes.

If the pantograph 7 is also attached to the partial covers 2 a-d of the Teleskopab cover 1 , the load is loaded by sliding mainly on the partial covers 2 a and 2 d, which with the moving device 4 of the main spindle head etc. of the industrial machine 5 and with the fastening device 6 of the industrial machine 5 are connected. The partial cover 2 a and 2 d tend to bend, and in such a case, stiffening plates (not shown in the drawings) on both or on one of the moving device 4 of the spindle head etc. of the industrial machine 5 and the fastening device 6 of the industrial machine 5 attached. The pantograph 7 can then be attached to the stiffening plates.

As shown in Fig. 9 and Fig. 10, connecting nipple 11 are provided at the crossing points of the connecting bolts 8 of the pantograph 7, so that a rotation is possible. The pantograph 7 is applied to the part covers 2 a- 2 d of the telescopic cover 1 fastened by the fastening nipple 9, wel surface at the contact points of the connecting pins 8 are attached, so that a rotation is possible. At this connection nipple 11 and nipple 9 of the pantograph 7 shock absorbing material in an annular shape 20 is with egg nem outer diameter slightly larger than the width of the Verbindungsbol zen 8, made of urethane, to the connection nipples 11 and to circuit nipples 9 of the pantograph 7 by the Ringunterlegscheibe 21 are brings and fastened by screws 22 so that a collision of the connec tion bolt 8 of the pantograph 7 is prevented and shocks are dampened, and breakage of the pantograph 7 , damage to the telescopic cover 1 and the formation of disturbing noises is prevented. As the material of the shock absorbing material in the form of a ring 20 , rubber, nitrile rubber, felt and all other materials can be used in addition to said urethane, as long as they have a shock absorbing effect. The outer diameter of the shock-absorbing material in the form of a ring 20 can be suitably applied to the width of the connecting bolt 8 of the pantograph 7 , and normally the diameter is approximately 1 to 5 mm larger than the width of the connecting bolt 8 . Furthermore, the thickness of the shock-absorbing material is approximately 0.5 to 3 mm.

As shown in Fig. 11, instead of using shock-absorbing material in a ring shape 20 made of urethane and inserted into the connec tion nipple 11 and connecting nipple 9 , a sliding control material in a ring shape 23 made of a magnet having an outer diameter of about the same Size as the width of the connecting bolt 8 of the Pantogra phen 7 can be inserted through a hole in the connecting nipple 11 and connecting nipple 9 and fastened by means of screws so that the sliding movement by the magnetic force of the sliding control material in ring shape 23 , made from a magnet, during the Contraction of the pantograph 7 is checked. In other words, the collision of Ver can connecting pin 8 by a slight increase in the sliding friction Verbin dung bolts 8 are prevented by means of magnetic force. The above-mentioned magnet such as ferrite and rare earth metals etc. are suitable as materials of the slide control materials 23 . The outer diameter of the Gleitkontrollmate rials in ring shape 23 may correspond to the width of the connecting bolt 8 of the Pantogra phen 7 or be slightly smaller. The thickness of the slip control material in ring shape 23 can be approximately 0.5 to 3.0 mm.

To attach the shock-absorbing material in the form of a ring 20 to the connec tion nipples 11 and connecting nipples 9 of the pantograph 7 can, as shown in FIG. 12, a sliding control material in the form of a ring 23 , produced by a magnet into the shock-absorbing material in the form of a ring 20 , made of urethane, with an outer diameter slightly larger than the width of the connecting pin 8 of the pantograph 7 , so that the impact of the collision between the connecting pins 8 is damped and / or such a collision is prevented when the connecting pins 8 are pulled together.

In addition, if the slidability of the telescopic cover 1 is not uniform, as shown in Fig. 13, the rollers 24 and the roller guide 25 can be attached to at least four corners, so that the slidability is improved.

As shown in Fig. 14, the slide control guide 26 is attached to a certain point of the partial cover 2 of the telescopic cover 1 by inserting it into the slide rail 27 , so that the slidability of the telescopic cover 1 is improved. For the slide control guide 26 , it is advisable to use NB Slideguide from Nippon Bearing Co., Ltd. to be used, these sliding guides made from the ball bearing or ball bearing flange, fastened in ring form (ball bearings fastened in a ring form). For example, the product numbers SEB, SEB-A, SEB-AY are considered suitable.
