Problems solved by technology

However, defects such as slag inclusions, pores, shrinkage cavities, and shrinkage porosity often occur in the preparation process of palletizing robot arms at present, so that the internal structure of the prepared palletizing robot arm is not high in density, hardness is not enough, and the load capacity is not high. Easy to be worn out, short service life

Abstract

The invention discloses a high-load wear resistant stacking machine arm and a preparation method. The high-load wear resistant stacking machine arm consists of the following components in percentage by weight: 3.0-4.5% of C, 12-25% of Cr, 0.6-0.9% of Si, 0.4-1.3% of Mo, 0.4-1.4% of Mn, 0.2-0.8% of Ni, 0.01-0.06% of V, 0.02-0.08% of S, 0.01-0.06% of P, and 0.01-0.06% of Zn. The preparation method comprises the following steps: firstly, waste steel and pig iron are molten and pre-deoxidized; then, ferrochromium, ferromanganese and ferrosilicon are added to obtain molten iron; silicon is added to perform final deoxidation and slagging; and after the molten iron is molded through pouring, the heat treatment and the surface treatment are performed. The stacking machine arm is excellent in high-load capacity and hardness, is simple and effective in preparation method, and is suitable for large-scale industrial popularization.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a high-load wear-resistant palletizing machine arm product and a preparation method. Background technique [0002] Palletizer, it is a device that automatically stacks bags, cartons or other packaging materials conveyed by the conveyor into stacks according to the working method required by the customer's process, and transports the stacked materials. At present, there are more automatic palletizers on the market. It is a high-tech product integrating machinery and electricity. The medium and low-level palletizers can meet the production needs of medium and low output. According to the required grouping method and number of layers, the palletizing of various products such as bags, rubber blocks, boxes, etc. can be completed. The optimized design makes the stacking shape compact and neat. Automatic palletizers are divided into two types according to the level of intelligence: robot...
