Problems solved by technology

However, high-alloy steel itself has poor plasticity and is a difficult-to-deform material.
[0009] The market demand for high-alloy steel special-shaped microwires is huge, but the traditional cold-drawing process cannot process high-alloy strip-shaped raw materials that are difficult to deform

Embodiment 1

[0060] A production process for difficult-to-deform high-alloy high-precision profiled materials, including:

[0061] S1: Pressing rollers, at least two pressing rollers are used as a group, and the surfaces of the two pressing rollers are grooved, so that when the two pressing rollers fit together and roll relative to each other, a forming channel with a constant shape is formed at the groove;

[0062] S2: Cold rolling, according to the different cross-sectional shapes of the products, select at least three sets of pressure rollers to obtain at least three different rows of channels, provide a traction force for the strip raw materials, so that the strip raw materials pass through the row channels in turn, and the strip raw materials pass through in turn When the forming channel is formed, the two pressure rollers forming the forming channel rotate, and the strip-shaped raw materials are rolled during the rotation process, so that the strip-shaped raw materials are gradually p...

Embodiment 3

[0077] A kind of production line of embodiment 1 or embodiment 2 produces the production line of special-shaped microfilament, as shown in the figure, along the moving direction of raw material successively,

[0078] The unwinding rack 1 is set at one end of the workbench 2. It rewinds and stores the raw materials, and provides an output channel for the raw materials. When the traction force drives the raw materials to move along the production line, the unwinding rack 1 rotates passively, and at the same time unwinds and outputs the raw materials;

[0079] The cold rolling mechanism includes at least three rolling mills, and the rolling mills are all arranged on the workbench 2. The rolling mills include at least two pressure rollers 31 that are slewably supported on the rolling stand 32 and roll relative to each other. The two pressure rollers 31 are grooved so that the two pressure rollers When the rollers 31 rotate relative to each other, a forming channel 33 with a certain...

Abstract

The invention discloses a difficultly-deformed high-alloy high-precision abnormal sectional material production technology and an abnormal microwire production line, and relates to the technical fieldof production and processing of high-alloy abnormal microwires. The difficultly-deformed high-alloy high-precision abnormal sectional material production technology comprises the steps of rolling, wherein at least two compression rollers are used as one group, and slots are formed in the surfaces of the two compression rollers, so that when the two compression rollers are fit with each other androll relatively, a molded channel with an invariable shape is formed by the slots; cold rolling, wherein at least three compression roller groups are selected, so that at least three different moldedchannels are formed, traction is provided for a bar material, when the bar material passes through the molded channels in sequence, the two compression rollers forming each molded channel rotate, during the rotation process, the bar material is pressed and rolled, and thus the bar material is gradually molded by pressing and rolling, and a crude product is acquired; and cold drawing: forming the crude product into a finished product via a drawing mold under the effect of the traction.

Description

technical field [0001] The invention relates to the technical field of production and processing of high-alloy special-shaped microwires, in particular to a production process for difficult-to-deform high-alloy high-precision special-shaped materials and a production line for special-shaped microwires. Background technique [0002] Shaped microfilament is a material with broad application prospects. As shown in the figure, it usually refers to a strip-shaped material with a "shaped" cross-section. [0003] The cross-sectional size of special-shaped microfilaments usually does not exceed 0.5×5mm. In the prior art, the microfilaments are usually produced by a “cold drawing” process. [0004] The cold drawing process is: [0005] First, the strip-shaped raw material passes through the drawing die. The cross-section of the raw material is usually rectangular or circular. There is a forming hole in the middle of the drawing die. The cross-sectional shape of the forming hole is t...
