Detailed Description
The structure and principles of such apparatus and method will be apparent to those skilled in the art from the following further description taken in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the cutting line in this embodiment is composed of a plurality of partial cutting lines, that is, the cutting line is individually processed into a plurality of partial cutting lines by using a dividing material, and then assembled to form an integral cutting line, the cutting line determines a shape according to a die-cut pattern, and is widened for post-processing, so that interchangeability and universality are achieved, and when a certain partial cutting line is damaged, only the partial cutting line needs to be replaced
That is, the entire knife line does not need to be replaced. And the width direction of the cutting edge at the top end of the cutting line and the sharp angle of the cutting line are formed by grinding, slow wire cutting or ultrasonic engraving and milling and grinding through a grinding machine, the machining residue at the sharp angle is less, the cleaning is thorough, and the smoothness of the cutting edge is high.
Referring to fig. 1-1, at the joint of one section of local knife line and the other section of local knife line, in order to ensure that the product die-cut has no seam, sharp corners are processed at the intersection points of the knife lines. Referring to fig. 1-2 and fig. 1-3, the connecting part of the partial knife line is shown under different conditions, and the shape of the connecting part can be adjusted according to actual needs.
Referring to fig. 2, 3, 4 and 5, the cutting-line-embedded circular-pressing hobbing tool comprises a base roll and a pressing block besides a cutting line, wherein the pressing block is directly attached to the cutting line and abuts against a mounting groove formed in the surface of the base roll, the cutting line is fixed in the mounting groove of the base roll through the pressing block, the pressing block is designed to be wedge-shaped, the pressing block is embedded into the base roll after the cutting line is placed in the base roll, the cutting line can be effectively pressed to be fixed on the base roll, the pressing block can be a section of integral pressing block matched with the integral cutting line, but preferably can be a section of local pressing block matched with the local cutting line, and each section of local cutting line is fixed respectively. Specifically, referring to fig. 8 and 9, the mounting groove on the surface of the base roll has two left and right side wall surfaces, one of which is a straight wall surface attached to one side wall surface of the blade line; the other side wall surface is an inclined surface which is matched with the pressing block and gradually expands from the bottom of the groove to the opening of the groove, and the wall surface of the pressing block matched with the mounting groove is gradually close to the knife line from top to bottom, so that a wedge-shaped structure is formed. Through the design, when the pressing block is gradually embedded into the mounting groove, the lateral clamping force can be provided for the cutter wire, so that the cutter wire is clamped and fastened in the groove. In combination with fig. 7, the prior art is to set up the straight flute of leading to long on the foundation roll, the mounted position of tool line relies on aluminium briquetting to guarantee, and aluminium briquetting needs to guarantee again with the groove limit position, multiple installation influences the precision easily, on the contrary, this embodiment is slotted along the tool line position, mounting groove one side is the vertical edge, a standard position location for the tool line, the opposite side has the inclination, a locking tool line for producing side thrust, rely on the precision of the vertical edge one side of the mounting groove of foundation roll to guarantee the location promptly, as long as the groove limit precision guarantees, the tool line leans on tight groove limit during installation tool line, the precision of tool line has just also been guaranteed.
Through this mode of inlaying the tool line, the straight wall face that at first relies on one side of mounting groove is as the benchmark of putting into of tool line, and then the reuse wedge-shaped briquetting compresses tightly the tool line, can accurately confirm the position of tool line on the base shaft, also can make closely laminating base shaft by the principle of wedge pressure boost, can install and debug the tool line height high-efficiently, improves the life of cutter.
Also, it is preferable that the bottom of the blade line be padded with a high hardness steel plate to prevent the blade line from denting on the base roll. In addition, the pressing block can be further provided with a connecting hole, a threaded hole is formed in the mounting groove corresponding to the connecting hole, the connecting hole and the threaded hole are used for being matched with a screw to achieve detachable connection between the pressing block and the mounting groove, and the connecting hole is preferably set to be a stepped hole, namely a counter bore.
Examples
As shown in fig. 10, firstly, for each segment of the partial knife line, the contour of the knife line is cut out by using a line cutting method; and then, a cutting edge of the superhard cutter line is made by using a grinding, wire-electrode cutting, electric spark or ultrasonic engraving and milling processing technology, then, a pressing block is cut by using a wire-electrode cutting or numerical control milling method, then, a countersunk hole is drilled, and a mounting groove which is matched with the shape of the cutter line is processed on the base roller.
And then, the local knife line and the local pressing block are placed into the mounting groove section by section, the local pressing block is connected with the mounting groove, and when the local pressing block is embedded into the mounting groove, a lateral clamping force can be applied to the local knife line in the mounting groove so as to fix the local knife line, so that the local knife line is fixed section by section and finally an integral knife line is formed on the surface of the base roller, and the assembly is completed.
