Embodiment 1

[0036] combine figure 1 , a kind of processing method of edge cutting scissors seat of the present embodiment, its process is:

[0037] Step 1, forging and processing the blank, after forging with three piers and three pulls, forming a rectangular body, and then annealing;

[0038] The specific forging process is as follows: heating the blank to 1090°C for the first pier thickening and elongation forging, the forging ratio is 1.6, which is the height ratio after one pier thickening and elongation processing; then the blank Heating to 890°C, carry out the second thickening and elongating forging, the forging ratio is 1.5; after the second forging, heat the workpiece to 870°C, carry out the third forging thickening, elongating forging, the forging ratio is 1.3; After the third forging, the workpiece is basically forged.

[0039] Step 2. Turning is carried out on a lathe, and its two end faces and four sides are respectively processed to form a rectangular body blank with a squ...

Embodiment 2

[0045] A kind of processing method of scraping edge scissors seat of the present embodiment, its process is:

[0046] Step 1, the forging processing blank is processed by forging with three piers and three pulls to form a rectangular blank, and then annealed;

[0047] The specific forging process is as follows: heating the blank to 1080°C for the first pier thickening and elongation forging, the forging ratio is 1.6, which is the height ratio after one pier thickening and elongation processing; then the blank Heating to 880°C, carry out the second thickening and elongating forging, the forging ratio is 1.5; after the second forging, heat the workpiece to 870°C, carry out the third forging thickening, elongating forging, the forging ratio is 1.3; After the third forging, the workpiece is basically forged.

[0048] Step 2. Turning is carried out on a lathe, and its two end faces and four sides are respectively processed to form a rectangular body 101 with a square cross section, ...

Abstract

The invention discloses a scrape chopper holder processing method and belongs to the field of cutter holder processing. The scrape chopper holder processing method comprises the following steps of step 1, forging and processing a blank, and then performing annealing treatment; step 2, performing turning with a lathe to form a rectangular body blank with the cross section being square, performing positioning by taking the side surface of a rectangular body as a reference, and processing a center hole; and step 3, determining a reference axis with the processed center hole, and processing cuttergrooves on the four side surfaces respectively; step 4, performing quenching and tempering treatment on the processed rectangular body, and then sequentially finishing the center hole and the cuttergrooves; step 5, performing finish milling on the cutter grooves, positioning point plane holes on the two end surfaces of the rectangular body blank, and then performing drilling processing; and step6, by taking a center shaft as a reference, processing an outer circular surface, and then performing grinding processing. According to the scrape chopper holder processing method provided by the invention, by adopting the rectangular body blank to perform processing, the center and the positioning reference are easily defined, and an ordinary lathe can be directly utilized to perform processing,so that the processing difficulty is lowered, and higher processing accuracy is reached.

Description

technical field [0001] The invention relates to the technical field of knife holders, and more specifically, relates to a method for processing edge cutting scissor holders. Background technique [0002] The chipping shear is the core equipment of the medium and heavy plate rolling production line, and it can replace the rolling double side shear in the medium and heavy plate production line. For medium and heavy plate production lines of small and medium iron and steel enterprises, the use of chipping shears can bring considerable economic benefits to the enterprise. The chipping shear is located behind the disc shear in the medium and heavy plate production line. Its function is to continuously chop the strip steel scrap edge cut by the disc shear, so that the scrap edge can be transported away from the operation line, which is beneficial to the collection and recycling of the scrap edge. [0003] When the scraper is used, a pair of knives cooperate with each other to ach...
