Embodiment Construction
[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0053] Such as Figure 1 to Figure 23 As shown, the manufacture method of the machine barrel wear-resistant sleeve of the present embodiment has the following steps:
[0054] 2. Material selection, select a metal plate 1 with a thickness of 8-12mm, and cut it into a set size;
[0055] 2. Heating, place the metal plate 1 cut into the specified size at a temperature of 1000-1100°C and heat it for 6-7 hours;
[0056] 3. Processing into semi-finished products, the metal plate 1 heated to 1000-1100°C is taken out of the heating furnace and placed in a mold to be molded into a semi-finished wear-resistant sleeve. After the semi-finished wear-resistant sleeve is taken out and cooled, the wear-resistant The pull bar 22 to prevent deformation is welded at the notch 21 of the sleeve;
[0057] Four, quenching, heating and quenching the wear-resistant ...

Abstract
A method for manufacturing a wear-resistant sleeve of a machine barrel, comprising the following steps: selecting a metal plate with a thickness of 8-12 mm, and cutting it into a set specification size; Warm for 6-7 hours; Take out the metal plate heated to 1000-1100°C from the heating furnace and place it in the mold to mold the semi-finished wear-resistant sleeve. After taking out the semi-finished wear-resistant sleeve and cooling it, put it on the wear-resistant sleeve Weld the upper tie bar at the gap; heat and quench the wear-resistant sleeve semi-finished product welded with the tie bar to the set hardness; process the quenched wear-resistant sleeve semi-finished product into the size requirement that the outer diameter closely matches the inner wall of the corresponding machine barrel; After the outer diameter is shaped, the semi-finished wear-resistant sleeve is cut off with a tool to form a finished wear-resistant sleeve with a "C"-shaped projection on the end surface. The advantage is that the wear-resistant sleeve is formed at one time, which saves materials, reduces the production cost of the wear-resistant sleeve, reduces processing difficulty, and reduces processing time.
Description
technical field [0001] The invention relates to a machine barrel manufacturing technology, in particular to a manufacturing method of a machine barrel wear-resistant sleeve. Background technique [0002] An existing Chinese invention patent application with the application number CN201610263853.3 titled "Ceramic-Aluminum Alloy Composite Barrel Bushing and Its Manufacturing Method" discloses a method for manufacturing an alloy composite barrel bushing, which is characterized in that it uses ceramic The advantages and characteristics of materials and metal materials are combined reasonably. The working surface of the bushing is made of ceramic material, which is used to bear the harsh working conditions of corrosion resistance and wear resistance; the outer layer of the bushing is made of aluminum alloy material, which plays the role of reducing impact and protecting the ceramic lining. The purpose of the present invention is to prolong the service life of the high-cost acces...
