Embodiment 1

[0033] Reference figure 2 , One A rolling processing method of a cutter head includes the following steps: (1) Selecting the hot-rolled iron plate or hot-rolled wire blank as the blade material and the high-carbon steel blank as the blade material, and the hot-rolled iron plate or hot-rolled wire Grind the billet and the high-carbon steel billet, and weld the high-carbon steel billet and the hot-rolled iron plate or hot-rolled wire billet into a raw material billet;

[0034] (2) Heat the raw material blank to the set temperature;

[0035] (3) Take out the raw material blank heated to the set temperature and then perform forging, insert the high-carbon steel blank into the hot-rolled iron plate or hot-rolled wire blank to obtain a rough-machined blank;

[0036] (4) The processed blank is rolled and shaped to obtain a finished blank;

[0037] (5) According to the shape of the cutter head to be processed, the finished blank is cut to obtain the cutter head.

[0038] In the step (1),...

Embodiment 2

[0053] Reference figure 1 , A rolling equipment for implementing the rolling processing method of the cutter head, comprising a frame 1, a driving device 2, a gearbox 3, an upper rolling drum 4 and a lower rolling drum 5. The upper rolling The rolling drum 4 is sleeved on the upper rotating shaft, the lower rolling drum sleeve 5 is installed on the lower rotating shaft, the upper rotating shaft and the lower rotating shaft are rotatably installed on the frame 1, and the upper rolling drum 4 and the lower rolling Between the cylinders 5 is a processing gap for the blank to pass through. A positioning pallet 6 for placing the blank is provided beside the processing gap. The positioning pallet 6 is installed on the frame 1, and the driving device 2 is installed on the frame. On 1, the drive device 2 is connected to the input shaft of the gearbox 3, and the output shaft of the gearbox 3 is connected to the upper shaft or the lower shaft.

[0054] The upper shaft and the lower shaft a...

Abstract

The invention provides a method for rolling and processing tool bits. The method comprises the following steps: (1) selecting hot-rolled iron plate or hot-rolled wire blank as tool body material and high-carbon steel blank as tool edge material, polishing the hot-rolled iron plate or hot-rolled wire blank and the high-carbon steel blank and welding the high-carbon steel blank and the hot-rolled iron plate or hot-rolled wire blank into a raw material blank; (2) heating the raw material blank to a set temperature; (3) obtaining a rough processed blank by taking out and forging the raw material blank heated to the set temperature and inlaying the high-carbon steel blank into the hot-rolled iron plate or hot-rolled wire blank; (4) obtaining a fine processed blank by rolling and shaping the rough processed blank; and (5) obtaining a tool bit by cutting the fine processed blank according to the shape of a to-be-processed tool bit. The invention also provides rolling equipment for realizing the rolling-processing method. The invention provides the method for rolling and processing tool bits, and the rolling equipment thereof, which have the advantages of adopting machining, greatly improving product qualification ratio, reducing processing cost, improving working efficiency, protecting environment and saving energy.

Description

Technical field [0001] The invention relates to a processing method and processing equipment of a cutter head. Background technique [0002] In the prior art, various knife heads, including scissors heads, tailor shears, kitchen knife heads, woodworking knife heads, lawn mowers and other mechanical knife heads, and other knife heads; There are usually two processing methods. One is to use high-carbon steel as the raw material for direct production. After the raw material is polished, it is directly punched into the required shape, and then subsequent processing is carried out according to different tools. In actual use, all high-carbon Steel cutters have the following shortcomings: 1. The blade has poor toughness, easy to break, and has a short service life; 2. High cost; another method is to use hot-rolled iron plates, wire materials and high-carbon steel materials to make joints. Hot-rolled iron plates and wire materials, high-carbon steel materials are used at the blade. Hot-r...
