Abstract
The invention relates to a grinding knife of a vertical leather edge grinding machine. The grinding knife is in a cylindrical body, the upper end of the grinding knife is a knife handle (10), the lower end of the grinding knife is a knife head (20), grinding materials (30) are spread on the surface of the lower end surface of the knife head (20), and the lower end surface of the knife head (20) is in a concave shape with the sunk center. The inner concave grinding knife is adopted, the problem of poor grinding quality in the prior art is solved, because the contact area of the grinding knife and leather materials is reduced, the friction force in the grinding process is reduced, the grinding quality is greatly improved, and the requirements of customers can be completely met.
Description
Technical field
The present invention relates to grinding tool, the sharpening particularly for the vertical edge polisher of cladding designs.
Background technology
Current cladding edging is all also adopt horizontal grinding tool to carry out grinding, this mould needs manually to hold cladding, the dangerous property of this method for grinding is larger, edging low precision and the problem such as to waste time and energy, the present inventor is on the basis of conventional art, devise vertical edge polisher, not only increase efficiency, also improve security and edging precision, but, obstacle is encountered in the process that development is whetted a knife, common tack is whetted a knife, because it is larger with cladding contact area, in grinding process, easily make cladding be out of shape, the edge ground is irregular, grinding depth is also difficult to reach requirement.
Summary of the invention
The invention provides a kind of sharpening of indent, adopt the method for end face indent, solve the technical problem of grinding quality difference in prior art.
The present invention is for solve the problems of the technologies described above and this sharpening that provides is cylindrical body, and its upper end is handle of a knife, and lower end is cutter head, and the surface, lower surface of described cutter head is laid with abrasive material, spill recessed centered by the lower surface of described cutter head.
Further improvement of the present invention is: described sharpening is stepped cylindrical, and the external diameter of cutter head end is greater than the external diameter of shank end.
Of the present invention improvement further is again: the lower surface of described cutter head is arc hole, truncated cone hole or conical hole, and the lower surface of described cutter head is provided with the flat surface grinding band of annular along cylindrical, described tool bit part outer round surface is also laid with abrasive material.
The present invention adopts above-mentioned inner concave shape to whet a knife, and solves the problem of grinding quality difference in prior art, and because sharpening and cladding contact area reduce, the frictional force in grinding process is reduced, and grinding quality is improved largely, and can meet the requirement of client completely.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic that inner concave shape of the present invention is whetted a knife.Fig. 2 is the appearance schematic diagram that inner concave shape of the present invention is whetted a knife.
Detailed description of the invention
In conjunction with above-mentioned accompanying drawing, specific embodiments of the invention are described.
From in Fig. 1 and Fig. 2, the sharpening of this vertical leather edge grinding machine is cylindrical body, and its upper end is handle of a knife 10, and lower end is cutter head 20, and the surface, lower surface of described cutter head 20 is laid with abrasive material 30, spill 22 recessed centered by the lower surface of described cutter head 20.The grinding end face of whetting a knife in the present invention adopts the shape of indent, in grinding process, reduce and whet a knife and the contact area of cladding, also avoid tack sharpening centre linear velocity too small and the problem such as cladding that is that cause is wrinkling simultaneously, can grinding quality be improved, ensure the neat of edging edge.
From in Fig. 1 and Fig. 2, described sharpening is stepped cylindrical, and the external diameter of described cutter head 20 end is greater than the external diameter of handle of a knife 10 end.Design this step in the present invention, be mainly convenient to the clamping of sharpening fixture, meanwhile, can also as positioning table use, prevent holder too close to tool bit part.
The lower surface of described cutter head 20 is arc hole (as shown in FIG.), truncated cone hole or conical hole, and the lower surface of described cutter head 20 is provided with the flat surface grinding band 21 of annular along cylindrical, described cutter head 20 part outer round surface is also laid with abrasive material 30.The quality problems that annular grinding strip mainly considers grinding are set in the present invention, if concave edge is too close to the cylindrical of cutter head, inevitable at edge formation wedge angle, undue reduction grinding area, inadequate and the irregular problem of grinding face of grinding force may be brought, therefore, the grinding strip that a plane is set is needed.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
