Problems solved by technology

The thickness of the knife blank formed by stamping and shearing of stainless steel plate is consistent. During the surface grinding process, it can be mechanized with a water mill for a rough grinding and a fine grinding. The efficiency is high, and large-scale batch production can be realized, but it is not wear-resistant. short life
The forged stainless steel knife blank has a more uniform carbide structure, finer grains, finer distribution, high hardness, good toughness, better wear resistance and impact resistance, and is deeply loved by consumers. , but the processing process is complicated, time-consuming and labor-intensive, and the cost is high
At the same time, the above two processing methods all have the defects of serious waste of materials and low utilization rate of raw materials.

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0022] A final forming process of a kitchen knife blank, comprising the following steps:

[0023] Step 1, making the pouring mold; combining figure 1 , figure 2 As shown, the pouring mold consists of a steel upper mold 1 and a steel lower mold 2. The lower surface of the steel upper mold 1 is a plane, the steel upper mold 1 is provided with an upper mold cooling water channel 1c, the steel upper mold 1 is provided with an upper mold water inlet pipe 1a and an upper mold outlet pipe 1b, and the upper mold enters The water pipe 1a, the upper mold cooling water channel 1c and the upper mold outlet pipe 1b are connected in sequence to cool down the steel upper mold 1 and facilitate rapid cooling of the molten steel in the pouring mold. The upper surface of the steel lower mold 2 is provided with a cavity 2c that matches the contour of the kitchen knife blank,...

Abstract

The invention discloses a final forming technique of a kitchen knife blank. The final forming technique of the kitchen knife blank comprises the following steps: manufacturing a casting mould which consists of an upper steel mould and a lower steel mould; filling cooling water to the casting mould; heating steel materials to molten steel; casting; and moving the upper steel mould downwards to be buckled with the lower steel mould under the action of a hydraulic drive system or a pneumatic drive system, cooling and the like. The formed kitchen knife blank has a smooth surface, is free from any pore, attractive in appearance and high in knife blank quality; the knife blank materials have stable compositions and are wear resistant and long in service life; no raw material wastes during forming, the material utilization ratio reaches 100%, and the manufacturing cost is saved; and the technique is simple in procedure, easy to implement, and small in labor intensity of workers, and the manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the field of cutting tool processing technology, and in particular relates to a final forming technology of a kitchen knife blank. Background technique [0002] There are usually two traditional methods of processing kitchen knife blanks: one is stamping and shearing of stainless steel plates, and the other is stainless steel knife blanks formed by forging. The thickness of the knife blank formed by stamping and shearing of stainless steel plate is consistent. During the surface grinding process, a water mill can be mechanized for a rough grinding and a fine grinding. The efficiency is high, and large-scale batch production can be realized, but it is not wear-resistant. Short life. The forged stainless steel knife blank has more uniform carbide structure, finer grains, finer distribution, high hardness, good toughness, better wear resistance and impact resistance, and is deeply loved by consumers. , but the processing process...
