Definitions
- the invention belongs to the construction of knives, suitable for the Cutting various solid, viscous and resistant fabrics, and can be used in the technique for cutting various synthetic materials, rubber, Plastics, adhesive bonds, etc., in the food industry for cutting frozen or solid products, in construction when cutting synthetic Parts or cover layers are used.
- the knife suitable for cutting the polymer materials that made a plate, a cutting edge, executed at least at one edge of the plate, the Teeth, executed on the cutting edge and its opposite surfaces with the opposite wide faces of the plate are connected, consists (1).
- the cutting edge is wavy, and the Wavy teeth are alternating transversely with respect to the longitudinal direction of the plate bent to each other.
- the increase is the effort, which one should add for cutting a resistant material, because the Teeth are saw-like bent in the transverse direction.
- the shape of the outer surface of Teeth do not allow to effectively cut solids because the wavy ones unsharpened form of teeth effective cutting into the solid substance limited.
- the cutting edge and the friction surfaces of the Hand tools usually lubricated with oil.
- oil In the above Constructions dissipates the oil during lubrication on the plate surface, flows from Teeth and from the cutting edge after a few longitudinal and transverse movements of the Knife blade off, whereby the effectiveness of the oil lubrication is lowered.
- the knife suitable for cutting frozen Products made from the plate, the cutting edge, running at least on one edge of the Plate, teeth, executed on the cutting edge and its opposite Surfaces are connected to the opposite wide faces of the plate, The teeth are filled with the gaps that are on the teeth the wide plate surface are (4).
- the teeth of this knife are as isosceles trapeze with the Straightness tip executed, and the gaps are with the cutting edge on the Basis of the trapezium for the formation of small points at the Straightness tip of the big tooth connected.
- this construction makes it possible to cut more firmly Fabrics, such as e.g. Frozen products, resulting in the effective loosening of the Substances and elimination of the hanging of particles of the substances to be cut off is reached at the cutting edge.
- the Teeth also transversely with respect to the longitudinal direction of the plate alternately to each other bent, whereby the force increases when cutting. Also reduced
- the speed of cutting increases and the effort required for cutting increases viscous substances, such as e.g.
- the cutting one Surface of this tooth is basically only pointed through Grooves between trapezoidal teeth and tapered cutting edge on the Basis of the trapezoid formed between the gaps. This will be the effective Use of the knife for cutting viscous substances impossible.
- Oil lubrication of the cutting edge will melt the oil on the plate surface because of the Areas that drain the oil from the grooves between the teeth and could hamper from the gaps are missing.
- the oil also gets out of the gaps that are free associated with the basis of the trapezium of the teeth to be processed on Draining fabric because the gaps directly with the straightness tip of the tooth are connected.
- the knife consisting of one Plate, a cutting edge, executed at least at one edge of the plate by the Forming the edge bevel of the wide plate surface, the teeth executed at the cutting edge with the formation of the tips for each tooth and their opposite surfaces with the opposite wide surfaces of Plate are connected (5).
- the tips of the teeth and the cutting edge from their forehead from the U-shaped interconnected grooves of the Plate edge formed and the side surfaces of the teeth are as U-shaped Recesses formed on the edge bevel of the wide plate surface.
- the tips of the teeth are different from the longitudinal axis of the plate removed, thereby gradually cutting the teeth into the depth of the processed substances is achieved.
- This technical solution improves the quality of the Cutting and closing the teeth in relation to each other in the Transverse direction of the plate.
- Limitations of this device are insufficiently high Speed of cutting different fabrics with different physical indices, relatively high cutting force, ineffective use of oil lubrication when cutting various substances, because the lubrication when cutting freely both on the plate, and on the processed substance drains off.
- the problem to be solved by the invention is the extension of the Assortment of fabrics to be worked on by cutting that are different from each other both in terms of strength, density, and viscosity differ without significant change in the speed of cutting and the effort required; in ensuring the effective use of lubrication and the effective removal of the products of cutting.
- the technical result achieved in the execution of the construction can be, increasing the speed of cutting, the reduction the effort of cutting, ensuring effective lubrication.
- the invention teaches a knife according to claim 1.
- the knife (FIGS. 1, 2) is formed from the plate 1.
- the cutting edge 2 is executed at least at one edge of the plate 1 by the formation of the edge bevel 3 of the wide surface 4 of the plate 1.
- the teeth 5 are made on the cutting edge 2 with the formation of the tips 6 for each tooth 5.
- the opposite surfaces of the teeth 5 are connected to the opposite wide surfaces 4 of the plate 1.
- the teeth 5 are provided with the gaps 7.
- the gaps 7 are located at the tips 6 of the teeth 5 on the distance l .
- the gaps 7 are located at the edge bevel 3 of the wide surface 4 of the plate. 1
- the gaps 7 are suitable for the effective lubrication, which is introduced into the surfaces of the teeth 5, which are connected to the wide surfaces 4 of the plate 1.
- the oil is effectively stopped on the chamfer 3 and on the surfaces of the teeth 5.
- the chamfer 3 serves as an additional obstacle to the flow of the lubricant on the wide surface 4 of the plate 1. Because the gaps 7 are at the tips 6 of the teeth 5 on the distance l , their cutting shape is not injured; the oil is introduced into the tip 6 of the tooth 5 in the sufficient amount and the main cutting edges of the teeth 5 are lubricated effectively.
- the distance l is selected constructively, and the teeth 5 are ground in one way or another according to the concrete shape resulting from the construction of the tooth 5.
- the longitudinal axis of the gap 7 is the length of the longitudinal axis of the Tooth 5 after.
- the angle of the V-shaped boundary 8 of the gap 7 is after the peak 6 of the tooth 5 directed. In this case, the whole surface of the tooth 5 becomes effective used; the area of the friction surface decreases during the work of the knife and the entire lubricated area increases.
- the gaps 7 are structurally U-shaped executed, whereby the method of their execution is simplified and the Lubrication in the gaps 7 during the longitudinal movements of the plate 1 during the Work of the knife is stopped.
- the tips 6 of the teeth 5 and the cutting edge 2 on the part of their forehead are from the U-shaped interconnected grooves 9 of the edge of the Plate 1 is formed, thereby the effectiveness of the cutting edge 2 is increased.
- the tips 6 of the teeth 5 and their side surface 10 in the shape of the U-shaped Recesses 11 formed on the edge bevel 3 of the wide surface. 4 are the plate 1, thereby the cutting side surfaces of the teeth. 5 be formed.
- the wide surfaces 4 of the plate 1 (Figs. 4, 5, 7, 8) are non-linear with the on the opposite and parallel axes in terms of Longitudinal axis of the plate 1 lying radius centers of the curvature executed.
- the Edge chamfer 3 of the wide surface 4 of the plate on which executed the gaps are formed by one of the odd surfaces of the plate 1.
- the cutting edge 2 and the teeth 5 are executed on two edges of the plate 1.
- Manufacturing are the teeth 5 of an edge of the plate 1 with respect to the teeth 5 of moved to the other edge of the plate 1.
- the longitudinal axis of the teeth 5 of an edge of Plate 1 is at the same distance between the longitudinal axes of the teeth 5 of the other edge of the plate. 1
- the bevel 3 to the Both sides of the wide surfaces 4 of the plate 1 for the purpose of forming the cutting edge. 2 (FIGS. 4, 5, 7, 8).
- the gaps 7 at the tips 6 of the teeth 5 on the edge bevels 3 of the two wide Surface 4 of the plate 1 (it is not shown on the Fig.)
- the knife When using the knife many advantages can be achieved, if the surfaces of the teeth 5 are formed only on one side of the plate 1.
- the knife may be part of the wide surface 4, which is free of teeth 5, can be sharpened effortlessly, without losing to have changed the shape of the teeth 5;
- the gaps 7 can be deep enough be formed, thereby improving the quality of lubrication, reduces the cost of the lubricant and increases the period of use the knife without relubrication;
- the gaps 7 together in one common recess can be connected (Fig. 10, 11), extending along the cutting edge located after.
- the limit of common recess will be in this case executed serpentine.
- the lubricant is in this case on the teeth. 5 stopped by the serpentine shape of the common recess.
- the floor The snake-like recess is made uneven to the kalkiumverseifte or liquid lubricants on the cutting edge 2 in addition to stop.
- the tips 6 of the teeth 5 and the side surfaces can by two oblique V-shaped recesses 14 are formed, which are located on the Edge bevel 3 of the wide surface 4 of the plate 1 zwichen the teeth. 5 located and narrowing in the direction of the longitudinal axis of the plate 1.
- the teeth 5 are in their cross-section U-shaped (Fig. 15) designed to thereby their longitudinal axis are orthogonal to the longitudinal axis of the plate 1; the teeth should be after the surface of the cutting edge 2 protrude and their side surfaces are in the Extending direction of the longitudinal axis of the plate 1 (Fig. 12).
- Figs. 15 cross-section U-shaped
- the wide surfaces 4 of the plate 1 can - as is the case in the case of separated gaps 7 (Fig. 3-8) is - curved with the on the opposite and parallel axes with respect to the longitudinal axis of the plate 1 lying radius centers of the curvature are executed (Fig. 13, 14).
- the called edge bevel 3 (at the common recess from the gaps 7 is formed) of the wide surface 4 of the plate 1 is by one of the curved Surfaces of the plate 1 formed.
- the cutting edge 2 and the teeth 5 can at two edges of the plate. 1 be executed (Fig. 12).
- the teeth 5 of an edge of the plate 1 are in terms of Teeth 5 of the other edge of the plate 1 is moved.
- the longitudinal axes of the teeth 5 an edge of the plate 1 are at the same distance between the longitudinal axes the teeth 5 of the other edge of the plate. 1
- the teeth become 5 with the gaps 7 with the e.g. Smeared margarine or diet oil.
- the Cutting method is the same as above.
- lubrication can not can be applied because, for example, when cutting, of the meat the juice Separately moistening a cutting edge 2 and teeth 5.
- the juice flows into the Gaps 7 or in the serpentine common recess through, damp the Bevel 3 and moist effective during the overflow between the Gaps 7 all working surfaces.
- the registered knife can be very cheap industrially for cutting various synthetic materials, polymer materials, rubber, plastics, various Adhesive bonds, e.g. in the chaining of the autoglass to the body, in the Food industry for cutting frozen or solid products, in construction for cutting synthetic parts or surface layers, in all technical Areas and in living conditions for cutting firmer, more resilient and viscous substances are needed.
