Embodiment Construction

[0033] Such as Figure 5-Figure 7 Shown is a schematic diagram of the structure of the device for making thin-walled plough disc harrow blades provided by the present invention, in which, Figure 5 , Image 6 Shows the blank to be ground on the positioning disc, Figure 7 The blank to be ground is not shown.

[0034] by Figure 5-Figure 7 It can be seen that the equipment of the present invention includes: a grinding mechanism with a grinding wheel for grinding the to-be-ground arc gap of the thin-walled plough disc harrow blade blank to make it into a crescent-shaped cutting edge; and a positioning mechanism , With a positioning disc on one side of the grinding wheel for fixing the blank, with an arc hole used to coincide with the arc gap of the blank to be ground; wherein the blank is a thin-walled and stamped The blank disc harrow blade with the arc notch to be ground on the edge, preferably, the blank part is a thin-walled steel part formed by stamping; wherein, when the bla...

Abstract

The invention discloses a method for manufacturing a thin-wall plough disc harrow blade. The method comprises the following steps that a blank piece of the thin-wall plough disc harrow blade is fixedon a positioning disc with an arc-shaped hole, so that a to-be-ground arc-shaped notch of the blank piece is overlapped with the arc-shaped hole; a grinding wheel, located on one side of the positioning disc, of a grinding device is used for performing grinding treatment on the to-be-ground arc-shaped notch of the blank piece so that the to-be-ground arc-shaped notch can be ground into a crescentcutting edge; and the blank piece is the thin-wall disc harrow piece blank piece which is formed by stamping, and the edge of the disc harrow piece blank piece is provided with the to-be-ground arc-shaped notch. According to the method for manufacturing the thin-wall plough disc harrow blade, the manufacturing process is simple, convenient and rapid, the cutting edge of the machined disc harrow blade is sharp, the production efficiency is remarkably improved; and in addition, the invention further provides equipment used for the method.

Description

Technical field [0001] The invention relates to the technical field of farming plows, in particular to a method and equipment for manufacturing notched disc harrows of thin-wall farming plows. Background technique [0002] At present, the manufacturing and processing methods of the semi-circular cutting edges of the notched disc harrows of the agricultural plough parts are mainly boring and milling machines. Because the material thickness of the notched disc harrow is between 3-6 mm, it is a thin-walled part. The workpiece vibrates severely during boring and milling, and the tool feed cannot be too large; and because of its semi-circular cutting edge, it is broken. Continuous cutting-edge processing; resulting in lower processing speed. On the other hand, during the cutting process, the displacement of the workpiece caused by the cutting of the tool is relatively large, the reliability of the workpiece is required to be high, and it takes more time to install the workpiece. Sum...
