Embodiment 1

[0024] Example 1: Select 16# manganese steel ingot as the raw material, put the raw material into the heating furnace, use the intermediate frequency sensor to raise the temperature of the raw material to 1200°C, then pull out both ends of the heated raw material and put it into the preforming mold Inside, when the temperature of the raw material is 1120°C, it is upset to obtain the preformed forging 1, and the structure of the preformed forging 1 is as follows figure 1 and figure 2 As shown, the height of the preformed forging 1 is 136 mm, the radius is 135.9 mm, and the radius of the fillet 2 of the preformed forging is larger. When the temperature of the preformed forging 1 is 1050°C, put the preformed forging 1 into the final forming die, forge and upset, and obtain the final forming forging 3, the structure of the final forming forging 3 is as follows image 3 and Figure 4 As shown, the periphery is a ring of flash 4, the middle is a continuous skin 6, and the radius ...

Embodiment 2

[0029] Example 2: Select 16# manganese steel ingot as raw material, put the raw material into a heating furnace, use medium frequency induction heating to raise the temperature of the raw material to 1170°C, then pull out both ends of the heated raw material and put it into the preforming mold Inside, when the raw material temperature is 1090°C, it is upset to obtain a preformed forging, the structure of the preformed forging is the same as in Example 1, the height of the preformed forging is 114 mm, the diameter is 120.4 mm, and the rounded corners of the preformed forging are Larger radius. When the temperature of the preformed forging is 1000°C, put the preformed forging into the final forming die, forge and upset, and obtain the final forging. The structure of the final forging is the same as that of Example 1, and the final forging is round The radius of the corner 5 is smaller than the radius of the fillet 2 of the preform forging. When the temperature of the final form...

Abstract

The invention relates to a forging technology of a cylinder lifting lug of an automobile, in particular to a technology for forging a lifting lug of a lift cylinder of an automobile. The technology comprises the following steps of: heating a raw material and drawing out the two ends of the raw material; putting the drawn raw material in a performing mould and upsetting to obtain a preformed forging of the cylinder lifting lug; continuing to upset the preformed forging in a final forming mould to obtain the finally formed forging of the cylinder lifting lug; removing burrs and overbark of the finally formed forging to obtain a cylinder lifting lug blank; normalizing the cylinder lifting lug blank and turning machining to obtain the finished product of the cylinder lifting lug. By the forging technology provided by the invention, the defects, such as large energy consumption, low material utilization rate, low production efficiency and the like in the prior art, can be overcome, and the finished cylinder lifting lug product has the advantages of good mechanical property and high safety.

Description

technical field [0001] The invention relates to a forging process for lifting lugs of automobile oil cylinders, in particular to a process for forging lifting lugs of lifting oil cylinders for automobiles. Background technique [0002] The hydraulic cylinder of the car is an extremely important part of the car. During the operation of the car, the hydraulic cylinder is not allowed to appear any disconnection, looseness and deformation. It has high requirements for durability, reliability and pressure resistance. Therefore, the hydraulic cylinder The process requirements for lifting lugs are also more stringent. At present, there are three main types of lifting lugs for oil cylinders on the market. The first type is castings. The material has a cast structure, coarse grains, poor performance of parts, and does not meet the safety and practicability of the product. It is rarely used today. The second type is split forgings, which are welded from parts. The process is complex,...
