Problems solved by technology

[0003] However, the use of forging to obtain part blanks has a long production process, and a series of molds need to be made according to the process flow (each process requires molds), and the quality requirements of the molds are very high.
Therefore, this method is not suitable for small batch production, cannot produce shearing tools with complex structures, and cannot meet the production requirements of some special shearing tools

Abstract

The invention discloses a technology for producing a tool part blank for cutting a thin-wall steel plate by virtue of a casting method. The technology for producing the tool part blank for cutting thethin-wall steel plate by virtue of the casting method comprises the following steps: alloy smelting, shell roasting, pouring, shell vibration, lifting-blasting, cutting, annealing, grinding, machining, and carbon restoration and hardening-tempering, wherein the used alloy comprises the following substance components in percentage: 0.35%-0.45% of C, 0.30%-0.45% of Si, 0.1%-0.4% of Mn, 1.0%-1.8% ofCr, 0.1%-0.4% of Mo, 1.0%-2.5% of W, not greater than 0.3% of V, less than 0.03% of impurity elements, and the balance Fe. According to the technology for producing the tool part blank for cutting the thin-wall steel plate by virtue of the casting method, the components of the adopted casting alloy are easy to control, and a casting die is simple to produce, and capable of producing special platecutting tools with complex shapes, and meeting small-batch and diversified market needs; and the part blank of a cutting tool is produced through the casting method, the part blank can be produced only by producing one die, and the production efficiency for the blank is greatly increased, so that the problem that the blank produced by a forging method is unsuitable for producing the special platecutting tools with complex structure, is solved.

Description

technical field [0001] The invention relates to the technical field of spare parts casting, in particular to a technology for producing blanks of tool parts for shearing thin-walled steel plates by a casting method. Background technique [0002] Thin-walled steel plates with a thickness of less than 1mm are commonly used in industry and residential life. This type of steel plate must be cut to a certain size and shape before it can be made into the desired product. Therefore, tools suitable for cutting thin-walled steel plates must be available. Tool parts for shearing thin-walled steel plates usually use tool steel profiles. First, the profiles are forged to obtain blank forgings, and then the blank forgings are processed and heat treated to obtain final parts. Commonly used scissors are made in this way. [0003] However, using the forging method to obtain the part blank has a long production process, and a series of molds need to be made according to the process flow (ea...
