Embodiment 1

[0044] A grinding and cutting method for making a cutter disc provided in an embodiment of the present invention includes the following steps:

[0045] In step S1 : controlling the hoisting device to hoist the columnar disk on the working turntable, and fixing the columnar disk on the working turntable by a fixture.

[0046] In the specific implementation process, the hoisting device is a separate device, the hoisting device can fix the columnar disc, and then the columnar disc is hoisted on the working turntable by moving and lifting, and fixed by the tooling fixture, wherein the tooling fixture can be a screw , nuts, and the structure for clamping the outer wall of the columnar disc or the inner wall of the through hole to fix the columnar disc, which will not be described in detail here.

[0047] In step S2: controlling the movement of the transverse feeding group, so that the edge position of the columnar disk is moved below the vertical scraper.

[0048] In the specific ...

Embodiment 2

[0074] Based on Example 1, such as image 3 As shown, the embodiment of the present application provides a schematic diagram of an application scenario of a grinding and cutting method for making a cutter disc. Such as image 3 It can be seen that the height difference between the highest position and the lowest position of the arc surface of the disk is 7mm, the maximum lateral distance of the arc surface of the disk is 14mm, and the distance between the outermost edge of the arc surface and the outer edge of the disk is 3mm . The height difference between the highest position and the lowest position of the arc-shaped surface of the disk, the maximum lateral distance of the arc-shaped surface of the disk, and the distance between the outermost edge of the arc-shaped surface and the outer edge of the disk are just an exemplary illustration. , in the actual grinding and cutting operation process, the size of the disc is subject to the actual situation, and will not be elabora...

Embodiment 3

[0082] In the specific implementation process, when cutting through the first embodiment, if each preset infeed distance is too large, resulting in an arc-shaped surface after grinding, the arc surface between each first infeed fixed distance There may be a certain protruding table between them, see Figure 4 Schematic diagram of the scene shown. In order to process the structure to form a smooth arc-shaped surface, the embodiment of the present application also provides an implementation mode, based on the first embodiment, combined with Figure 5 As shown, the grinding and cutting method provided by the embodiment of the present application also includes the following steps:

[0083] Step S1-Step S7 can be referred to the embodiment of a pair of grinding and cutting methods in the embodiment, which will not be elaborated here, and the embodiment of the present application only elaborates the following implementation steps in detail.

[0084] In step S8: when the vertical s...

Abstract

The invention is suitable for the technical field of metal disc abrasion cutting, and provides an abrasion cutting method for manufacturing cutter discs. A columnar disc is driven to transversely movethrough a transverse feeding set, a vertical scraper is driven to cut the columnar disc through a first vertical feeding set, and the columnar disc is driven to rotate through a working turntable, sothat the disc is cut under rotation of the vertical scraper and the disc; the transverse feeding set is controlled to drive the columnar disc to transversely move by a preset distance, and the vertical scraper is controlled to cut the rotated disc under a certain cutter feeding depth; the cutter feeding depth at this time is larger than the cutter feeding depth for the first time; and the operation is repeated, the feeding depth of the vertical scraper is gradually increased from the outer edge to inner edge surface of the columnar disc, so that an arc surface is gradually formed from the outer edge to the inner edge of the disc, a disc with the arc surface is formed, and the working efficiency of cutter preparation is improved.

Description

technical field [0001] The invention belongs to the technical field of metal disc grinding and cutting, and in particular relates to a grinding and cutting method for making a cutter disc. Background technique [0002] In the process of making specific knives, it is often necessary to cut a whole piece of steel into a disc-shaped steel, then punch a hole in the middle of the disc-shaped steel, and then grind and cut it into a certain arc along the outer edge to the center of the disc-shaped steel surface , and punch and cut holes in the curved disc-shaped steel to form a knife. [0003] In the existing technology, such as figure 1 Shown is the disk for making cutters, the through holes coaxial with the center of the disk are punched between the disks by a punching machine, and an arc surface is formed from the edge of the disk to the center of the disk. In order to achieve the production of discs in the prior art, because the weight of the disc is relatively heavy, reachin...
