Detailed Description
The invention will now be further described with reference to the accompanying drawings and specific examples, which are not intended to limit the invention.
The invention provides a contour forming blade for processing stainless steel products, which is arranged on a cutter handle 1 as shown in figures 1 to 5, wherein a plurality of cutter grooves are concentrically arranged at the end part of the cutter handle 1, a square blade body 2 is arranged in each cutter groove, four sides of the blade body 2 are respectively provided with a first cutting edge 3, two sides of the first cutting edge 3 are respectively provided with a second cutting edge 4, the first cutting edge 3 is connected with two adjacent second cutting edges 4 to form a concave shape, a contour forming blade can replace two hard alloy cutters to finish a molding surface allowance removing process, a certain production cost is saved, in addition, the first cutting edge 3 and the adjacent second cutting edges 4 form an obtuse angle, and the included angle has the value range ofNamely, the value range of A marked in figures 2 and 3 is [1 DEG, 2 DEG ], the point of the right-angle contour of the blade in the process of machining is the outermost point, the rest of the straight line part does not cut the workpiece, but sliding friction occurs between the straight line part and the workpiece, so that the blade has abnormal friction and wear.
The first cutting edge 3 and the adjacent second cutting edge 4 are connected through a fillet with the radius of 0.2mm, the fillet is firstly contacted with a workpiece and is positioned at a processing boundary, the abrasion is serious, and the quality influence on a processed product is serious, so that the R0.2 arc position and the boundary abrasion serious region, namely the front cutter surface of the first cutting edge 3 forms a negative front angle with the horizontal direction, the value range of the negative front angle is [ -10 degrees and-15 degrees ] ], namely the value range of B in figure 4 is [ -10 degrees and-15 degrees ] ], a protective cutting edge is formed, the boundary abrasion in the processing process of the blade body 2 is solved, and the product size and appearance consistency are ensured.
The front edge of the blade body 2 is also provided with a cutting groove 5 for chip removal, the cutting groove 5 is smoothly connected with the front cutter surface of the second cutting edge 4, the radius value range of the cutting groove 5 is [0.8mm,1.2mm ], the influence of the excessive cutting groove on the integral strength of the blade body 2 is avoided, and the integral structural rigidity of the blade body 2 is ensured.
Because the existing profile forming blade is difficult to realize orderly indexing and checking work in the indexing process by operators when the existing profile forming blade is put into use on a production line, the part of a group of used blades is too frequently used and has reached the service life, so that a group of blades cannot realize stable processing, and the blades are often required to be replaced in advance, different identifiers 6 are respectively arranged at the top corners of the blade bodies 2, as shown by reference numeral A, B, C, D in figure 2, and when in processing, the cutting edges on the blade bodies 2 are used in turn according to the set sequence, such as ABCD, so that the profile forming blade is convenient for installers to review, the service life of the blade is further prolonged, and the maintenance and replacement cost of the blade is reduced.
The foregoing describes preferred embodiments of the present invention; it is to be understood that the invention is not limited to the specific embodiments described above, wherein devices and structures not described in detail are to be understood as being implemented in a manner common in the art; any person skilled in the art will make many possible variations and modifications, or adaptations to equivalent embodiments without departing from the technical solution of the present invention, which do not affect the essential content of the present invention; therefore, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention still fall within the scope of the technical solution of the present invention.
