Description
Technical field
The present invention relates to a kind of guide shoe of combing head of the combing cover plate that is used for carding machine, this guide shoe can in axial direction be pulled to described cover plate head and get on, guide shoe comprises at least one slipper, this slipper can be set between cover plate head and the carding machine bend, and is included in the slidingsurface that cooperates with the carding machine bend towards a side of described bend.The invention still further relates to the method for a kind of cover plate head, combing cover plate and a kind of production combing cover plate.
Background technology
Cover plate with interchangeable guide shoe is known in US 4,300,266.Cover plate has the standing part that is used for axially promoting guide shoe in its outer end.Be provided with recessed surface on the standing part of cover plate, this recessed surface is positioned at a side that can be transported on the carding machine bend, and this recessed surface is along the bottom surface of described guide shoe and go.The two ends adjacency of sidewall and this bottom surface, their height is corresponding with the height of standing part, is provided with intilted part at the upper end of this sidewall, and this sloping portion surrounds the directed forward or directed backward top edge of cover plate.In some exemplary embodiment, described guide shoe comprises additional brake or clamping device, and described brake or clamping device will stop guide shoe any slip in the axial direction.
Described guide shoe is made up of stamping parts, and this stamping parts is by making through the phosphor bronze of quenching and tempering.The stamping parts of this relative thin obtains its described just now shape by suitable bending.In this case, from above-mentioned bottom surface to sidewall and the crossover position from the sidewall to top need bending, this bottom surface itself must be through by bending to obtain concave.
Substantially, carrying out each bending step like this makes the free cross section between the each several part be less than the cross section of standing part on the cover plate.Therefore, for guide shoe being pushed on the cover plate, be necessary that crooked this top part makes its bottom surface away from guide shoe.In this case, because each several part has identical materials thickness, all parts of guide shoe all are out of shape, and the crushed element that clearly limits just is not set.
On the standing part that can be pushed to cover plate, the brake component that can select on the guide shoe to be provided with also must be pressed out each other separately according to their design.
If top part and selectable brake portion are released again after pushing open, guide shoe is fixed in the axial direction by elastic force.In this case, the elastic part that limits is not set clearly but guide shoe is done the as a whole distortion that stands.
By US 4,300,266 known guide shoes have many shortcomings.Therefore, because a plurality of parts must be bent to away from each other, it on the cover board is very difficult obviously guide shoe being installed.In this case, guide shoe always has by the risk of plastic deformation, and the result becomes guide shoe can not use.Since a large amount of wedge angle and edges, the risk that the assembler is come to harm.
And, because its radius on above-mentioned bottom surface is significantly less than the concave surface bended of the typical radius of carding machine bend, disclosed guide shoe only is supported on the bend of carding machine at its directed forward lower limb and directed backward lower limb, this only produces two linear slide surfaces, and this will cause sliding capability difference and high wearing and tearing.
In addition, shown in the guide shoe, the combing part of combing cover plate is that card clothing can not be guaranteed with respect to the correct location of drum cylinder.Be subjected to the influence of relatively large manufacturing tolerance with the guide shoe of punching press and bending method production, this sweep can not be in all sides all near the surface of the standing part of combing cover plate.Yet, under the effect of the power that in the carding machine running, is produced, the standing part of carding machine cover plate and the gap between the guide shoe cause the strain of guide shoe, because in continuous running, for example when being positioned over the combing cover plate on the carding machine bend, these power are variable, thus the distance between the cylinder of the combing part of combing cover plate and carding machine change constantly, this then cause incomplete combing result.The elasticity of whole elastic bend part branch necessity has been aggravated this problem.
And especially disadvantageously, effectively slidingsurface just in time is arranged on the crossover position of above-mentioned bottom surface to sidewall, promptly in the knee.On the part of this bending, can not produce slidingsurface with required precision.Thereby the side of the outside sensing of curved edge has concave usually on its longitudinal direction, this means two of the known guide shoe slidingsurfaces that extend at axial direction each all in their center from carding machine bend projection.In other words, in many cases, guide shoe only is positioned on the carding machine bend on its four lower angles.
This situation frequently appears at when directed forward slidingsurface and when the slidingsurface of orientation is not exactly parallel the setting backward.If in these cases, the combing cover plate is directed at carding machine bend top, and strain will take place guide shoe, the result, and the distance of combing cover plate and its position with respect to drum cylinder just can not determined by enough accurate.Especially, the combing cover plate may appear around its longitudinal axis distortion.Generally speaking, current needed carding quality can not be by by US 4,300,266 known guide shoes and obtaining.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of guide shoe and be used to receive the cover plate head of guide shoe according to the present invention, thereby avoided the known defective of prior art.Another object of the present invention provides the method for a kind of combing cover plate and a kind of production combing cover plate and avoids described defective.
Above-mentioned purpose is to realize by the guide shoe with corresponding independent claims feature, cover plate head, combing cover plate and method.
Slipper according to guide shoe of the present invention has the contact surface that is positioned at towards the first side of cover plate, this contact surface can be positioned on the respective support surface of cover plate head very close to each otherly, and this has just been avoided any play of combing cover plate perpendicular to the carding machine bend.In addition, because combing cover plate or cover plate head make the guide shoe hardening, the strain of the slidingsurface that the strain of guide shoe is particularly caused by the external force that acts on the guide shoe has just been avoided.
It is planar sliding surface that guide shoe preferably is designed to.Because the radius of carding machine bend is very big for the stretching, extension of slidingsurface on combing cover plate moving direction, the proportionate relationship of guide shoe that is obtained and carding machine bend and smooth guide shoe slide the proportionate relationship that obtained much at one being on the slidingsurface of planar design.Particularly, when slipper contacts with the carding machine bend, on this two articles, only there are slight distortion and stress to produce.Yet the ellipticity of calculating by hertz formula causes the real contact area between slipper and the carding machine bend relatively large.Thereby smooth slidingsurface causes improvement and combing cover plate the definite guiding on this slip bend of guide shoe in the slip behavior on the carding machine bend.
Yet, particularly preferably being, slidingsurface has concave curvature, and the radius of its bending radius and carding machine bend adapts.Described radius is identical in theory., if the ellipticity that produces has caused the actual contact face between slipper and carding machine bend, this contact-making surface extends on the main part of slipper, and some difference of this radius just can be allowed to.
The radius that is complementary has been avoided the strain of slipper greatly, and thereby has guaranteed the combing cover plate of carding machine and the constant distance between the cylinder.The combing cover plate has also obtained avoiding around the inclination of its longitudinal axis.Use conventional method, for example use cutting process, particularly by grinding, slidingsurface can be produced with high accuracy.
In principle, can use all known means to be fixed on the cover plate head, for example, can consider to use riveted joint or bonding according to guide shoe of the present invention.Yet, preferably guide shoe is detachably fixed on the cover plate head, for example, can consider to use to be threaded or clamping, this helps changing the guide shoe of damaging.
Yet, particularly preferably be elasticity and connect.For this purpose, guide shoe has and is used for contact surface is pressed in elastic part on the stayed surface.In this case, the grip portion of elastic part is designed to cooperate with the step of cover plate head, this has been avoided that guide shoe leaves the cover plate head any endwisely slip and, and guide shoe thereby can easily be mounted and dismounted perpendicular to the play of the slidingsurface between guide shoe and combing cover plate.
Preferably, this at least one elastic part in axial direction extends on the zone of slidingsurface at least, and this will cause guide shoe to be fixed on especially reliably on the cover plate head.
Elastic part preferably has hook-shaped cross section.Particularly advantageous in this case is barb shape, and its grip portion conforms to the intilted step of cover plate head, and this can be avoided the horizontal slip of grip portion.Elastic part particularly preferably is the shape with round hook, and the grip portion of round hook can engage with the tilt stage of cover plate head equally.In this case, the acquisition elastic force that the strain of the circular portion by hook can be favourable.Therefore the strain of other parts of the guide shoe particularly strain of slidingsurface can be avoided, and causes guide shoe especially firmly and reliably to be fixed on the cover plate head.
In addition, particularly advantageously be that at least one elastic part is by being pushed on the cover plate head and by pretension.Thereby elastic part is produced described elastic force by strain when being pushed on the cover plate head at guide shoe.For convenience guide shoe is pushed to the combing cover plate and gets on, guide shoe can have the sloping portion that is arranged on its upper end towards the combing cover plate (head end).Sloping portion for example also can be arranged on the elastic part, thereby makes things convenient for pretension.
At least one brake component preferably is set to be used at the fixing guide shoe of axial direction.This brake component is designed to cooperate with contrary brake component on the cover plate head, brake component can be a cam lobe (cam lobe) for example, this cam lobe is engaged on the contrary brake component as concave design, yet, it also is practicable cam lobe being set on the cover plate head and forming depression on guide shoe, and this pairing of brake component and contrary brake component has produced guide shoe firm especially cooperation on the cover plate head.
The bar of in axial direction arranging is set is used for preventing that any play with respect to the combing cover plate direction of motion also is favourable between guide shoe and cover plate head.This can abut against the side of elastic part, and helps the pretension of elastic part by size interference (oversize).Generally, this advantageously fixedly contributes for the no play (play-free) of guide shoe on the cover plate head.
Advantageously, guide shoe forms with a member.For example, it can accurately be designed to a foundry goods or one and mills product (milled part).
Guide shoe or at least slidingsurface advantageously be made of plastics.The application of plastics is to have benefited from its light weight, good machining property and favourable sliding capability.The slip additive by way of example, such as carbon or teflon (Teflon), can preferably be added on the slidingsurface, and this has guaranteed that guide shoe especially flat on the carding machine bend moves quietly, and makes that the wearing and tearing of carding machine bend and guide shoe are very little.
Slipper especially preferably has such thickness, and promptly slidingsurface can be by mach thickness.The thickness of slipper is drawn by the distance of slidingsurface to contact surface.Slidingsurface can especially accurately be made by machined.In this case, can be processed to have high accuracy with for example one or more machining steps as foundry goods or the blank that mills the product manufacturing.
Slidingsurface preferably has at least one rinse bath (cleaning groove).Rinse bath is used to hold impurity, for example is positioned at the sand grain on the carding machine bend, has so just avoided grit to be blocked between slidingsurface and the carding machine bend.If rinse bath is obliquely installed, dust granule just can be removed from the carding machine bend especially apace.Particularly, thus the life-span of having improved the carding machine bend.
Guide shoe is design by this way preferably, promptly connecting by being connected with the rigidity (positive) of cover plate head of promote forming or non-rigid (non-positive) is enough reliably, does not feasiblely need extra bonding for sustain the load that produces in operation process.Needed load capacity can be by being guaranteed the material of guide shoe and cover plate head and the suitable selection of shape, in this layout of spring and brake component particularly importantly.
In particularly advantageous another improvement project, guide shoe designs in such a manner, be it with the rigidity of cover plate head be enough reliable with nonrigid the connection, make that slidingsurface can be by machined, and will not separate from the cover plate head by guide shoe, perhaps can not occur by caused elasticity of the power that produces in the machining process or plastic deformation.If guide shoe is by suitably moulding, also can save extra bonding at this.By after being pushed to the cover plate head to the reprocessing of slidingsurface, just making slidingsurface especially accurately locate with respect to the combing part of combing cover plate becomes possibility.If slipper and thereby slidingsurface in the process that is pushed to the cover plate head by elasticity or plastic deformation, this unacceptable distortion can obtain by follow-up processing technology correcting.
And advantageously, the part of combing cover plate is being carried out in the machining process, the support section that will be used to locate the cover plate head be arranged on the corresponding cover plate head away from stayed surface towards a side.If the height of guide shoe above contact surface leaves surface-supported distance less than support section towards surface-supported boundary face, then is favourable.Support section thereby can be used in location combing cover plate, guide shoe is pushed into and is used for carrying out machined on the combing cover plate in laying the container of processing equipment.Thereby for example, it is feasible using support section in the machining process of the slidingsurface that newly is positioned over the guide shoe on the support section.If may be because after wearing and tearing be replaced, the combing part of the combing cover plate of new installation also can use this support section in the time will carrying out machined and for example polish.Because support section has the fixed position with respect to the installed part first of combing cover plate, so new installed part can especially accurately be located, thereby has accurate fixed position with respect to installed part first.
Guide shoe preferably has U-shaped cross-section, wherein, at least one slipper is arranged on the bottom of this U-shaped, so, the cover plate head preferably has rectangle or box-shaped cross section, after the promotion of guide shoe, between two shanks of the U-shaped of guide shoe, this has produced compact especially connection to this cross section between guide shoe and cover plate head at least in part.
Guide shoe can point to a side of the direction of motion and have slipper in its side of pointing to the direction opposite with the direction of motion at it, and this can be avoided the inclination around its longitudinal axis during crossing the slip of carding machine bend of combing cover plate.It itself is the plane that each slidingsurface is designed to.This slidingsurface can tilt toward each other, but because the relatively large radius of carding machine bend, this is unnecessary basically.
If guide shoe is made into U-shaped, described elastic part just advantageously is formed on two shanks of U-shaped.In this case, preferably, the grip portion that is formed on the elastic part on the shank inwardly points to, and all is bonded in each case on the preferred intilted described step of cover plate head, and this is connected with regard to having produced the firm especially of guide shoe and cover plate head reliably.
And, can be advantageously, each shank has parts of tooth in its upper end towards the combing cover plate, and this parts of tooth matches with the corresponding tooth-shape structure of cover plate head, has prevented the bending that each shank particularly outwards points to.This feature also helps guide shoe reliably in place on the cover plate head.
Cover plate head according to the present invention is configured in axial direction promote according to guide shoe of the present invention, and for this reason, the cover plate head has the shape corresponding to guide shoe.
Preferably, at least one stayed surface is set at towards a side of at least one slidingsurface of guide shoe.When the slidingsurface that is pushed into the guide shoe on the combing cover plate was carried out machined, the combing cover plate can be located exactly with respect to processing equipment.
If guide shoe has the U-shaped shape, it is particularly advantageous that the cover plate head has the box-shaped exterior section that is used to promote guide shoe.In this case, pointing on the side and a side of its moving direction, can be provided for engaging respectively the step of a grip portion of guide shoe in directed in opposite directions.
If this step is set in the core of exterior section,, will be particularly advantageous being used in abutting connection with between the stayed surface and reference planes of the contact surface of guide shoe.In this case, the cover plate head away from stayed surface towards the guide shoe do not shifted onto on it of a side cover, particularly advantageous is that the slidingsurface that has been pulled to top guide shoe will be carried out machined.In addition, in this case, the upside of cover plate head can be used to support the continuous conveyor of transportation cover plate head.
And advantageously, the cover plate head has a described stayed surface at an end that points to the direction of motion and at an end of directed in opposite directions, supports a contact surface of guide shoe respectively.
And the cover plate head can have the depression of the retaining part that is used to hold continuous conveyor, and this conveyer belt is used for the supporting cover wrench, and this just can guarantee the secure fixation of cover plate head on continuous conveyor.
