Embodiment 1

[0014] Embodiment 1: the preparation of plum blossom wrench

[0015] 1) Casting: Put 3.6% of titanium, 0.18% of chromium, 0.6% of aluminum and the rest of the copper into a vacuum furnace to melt at 1870°C, keep warm for 10 minutes and then cast in a vacuum state; After cooling, it is out of the furnace; after the casting is completely cooled, the sprue is cut and polished.

[0016] 2) Quenching: Put the cut gate and polished workpiece into a heat treatment furnace and heat it at 870°C for 10 minutes, then put it out of the furnace and quickly put it into a cooling liquid whose medium is clean water at room temperature for rapid cooling.

[0017] 3) Gold processing: The workpiece after quenching treatment is subjected to the following gold processing: broaching plum blossom hole----chamfering.

[0018] 4) Artificial aging treatment: Put the workpiece processed by the above gold into the heat treatment furnace and heat it at 440°C, keep it warm for 2 hours and 30 minutes, and ...

Embodiment 2

[0020] Embodiment 2: the preparation of chisel

[0021] 1) Casting: Put 3.8% of titanium, 0.2% of chromium, 0.8% of aluminum and the rest of the copper into a vacuum furnace to melt at 1890°C, keep warm for 12 minutes and then cast in a vacuum state; After cooling, it is out of the furnace; after the casting is completely cooled, the sprue is cut and polished.

[0022] 2) Quenching: Put the cut gate and polished workpiece into the heat treatment furnace, heat it at 900°C and keep it warm for 12 minutes, then put it out of the furnace and quickly put it into the cooling liquid whose medium is clear water at normal temperature to cool quickly, and the workpiece after quenching treatment After grinding, put the polished workpiece into the heat treatment furnace and heat it at 450°C, keep it warm for 2 hours and 40 minutes, and then cool it with the furnace; the completely cooled workpiece is polished to become the finished chisel. The main properties of the chisel at this time a...

Abstract

This invention relates to high performance explosion-proof titanium alloy tool, which alloy containing: titanium 3.5-4%, chromium 0.15-0.25%, aluminium 0.5-1% and the rest copper. The production steps are: (1)heating the raw materials at temperature of 1880+-20deg.C for 10+g2min, and then casting the alloy into semi-product at vacuum condition; (2), the semi-product, after cutting gate-stub and burnishing, putting into heat-treatment oven, being heated at temperature of 880+-20deg.C, and keeping at that temperature for 10+-2min, and then quick cooling by putting the same into ambient temperature water as coolant; (3), proceeding artificial aging by putting the product into heat treatment oven at temperature of 430+-20deg.C for 2-3Hrs, and then natural cooling in the oven.

Description

technical field [0001] The invention relates to a high-performance titanium alloy explosion-proof tool and a preparation method thereof. Background technique [0002] At present, domestic explosion-proof tools are mainly made of aluminum bronze or beryllium bronze. The explosion-proof tools made of aluminum bronze materials have low hardness and strength, among which the hardness is above HRC25, and the torque value reaches the B and D series (low series) stipulated in the relevant national explosion-proof tool standards QB / T2613.1-7-2003. The hardness and strength of explosion-proof tools made of beryllium bronze materials are higher than those of aluminum bronze materials, and their hardness and strength are higher. Among them, the hardness is above HRC35, and the torque value meets the relevant national standards for explosion-proof tools QB / T2613.1~7-2003. A and C series (high series). [0003] The disadvantage of aluminum bronze explosion-proof tools is its low perfor...
