Problems solved by technology

In the prior art, most of the workpiece transfer between processes and some of the processes are completed manually, and the dry and hot microclimate environment, noise, vibration and air polluted by smog, etc., workers are exposed to harmful environments and occupational hazards , causing serious damage to the body; and the existing automobile control arm forging production line is not high in automation, the labor intensity of the staff is high, the production efficiency is low, the yield is low, and the product quality is not high; most of the existing automobile control arm production lines are not Including heat treatment equipment, that is, the heat treatment process and the automobile control arm forging production line are intermittent and not connected to each other. After the product is forged and formed, it cannot be heat treated in time, and the product is easily damaged during the process of being transported from the production line area to the heat treatment area. The production cycle is long. And affect product quality; the common multi-dimensional linear arrangement of the production line, the layout is not reasonable enough, the connection of each working area is not smooth enough, and the space utilization rate is low
[0004] Although the forging process of some automobile control arms simplifies the processing procedure and improves the production efficiency, the quality of the products is uneven, and the heating process is mostly completed directly by an electric heating furnace. The entire furnace body is heated, and the heating speed is slow, resulting in waste of energy and The heating speed and heating uniformity of the blank are difficult to guarantee, prolonging the production cycle and reducing production efficiency. If the heating time is too short, the temperature of the blank will not meet the standard, the heating will be uneven, the product will have many internal defects, the stiffness and strength will not meet the standard, and the service life will be short. reduce product quality

Embodiment 1

[0088] This embodiment provides a kind of forging production line of automobile control arm, such as figure 1 with figure 2 As shown, the automobile control arm forging production line includes a billet making area, a die forging area and a heat treatment area arranged in sequence according to the production process, and the billet making area, the die forging area and the heat treatment area are arranged in an "S" shape , optimize the layout of the production line according to the production process, save floor space, improve space utilization, and there are multiple manipulators 10 for picking and delivering workpieces between each working area;

[0089] The billet making area includes a first heating furnace 1 and a roll forger 2, the first heating furnace 1 is used to heat the billet, and the billet is transported to the roll forger 2 by the manipulator 10, the The roll forging machine 2 is used for pre-forging and pressing the billet, and transporting the pre-forging an...

Embodiment 2

[0129] The structure of the automobile control arm forging production line provided in this embodiment is basically similar to that of the automobile control arm forging production line in Embodiment 1, except for the jet guide structure 83 . Such as Figure 10 with Figure 11 As shown, the jet flow guide structure 83 includes a jet flow plate 831, the jet flow plate 831 is connected to the inner wall of the furnace body 81, and the surface of the jet flow plate 831 is provided with a plurality of elongated jet flow grooves 833, The length direction of the jetting groove 833 is consistent with the conveying direction of the conveying mechanism 84 , a plurality of the jetting grooves 833 are arranged at intervals, and a plurality of the gas ejection ports 8321 are evenly distributed on the bottom of the jetting groove 833 . Adopting the structure of the jet flow groove 833 can effectively increase the amount of gas ejected, further increase the heating speed, and has a simple ...

Embodiment 3

[0132] The structure of the automobile control arm forging production line provided in this embodiment is basically similar to the structure of the automobile control arm forging production line in Embodiment 1, the difference is that the roll forging machine 2, the pre-forging press 5, the final forging Both the press 6 and the shaping punch 7 include an automatic heating system, that is, the above-mentioned equipment can automatically heat its mold when it is working. Preferably, the manipulator includes an automatic lubricating spray system. Before the manipulator grabs the workpiece and puts it into the mold in the next step, the automatic lubricating spray system automatically sprays lubricating spray into the mold, and then The captured workpiece is put into the mold for subsequent demoulding.

Abstract

The invention discloses an automobile control arm forging production line. The production line comprises a blank making area, a die forging area and a heat treatment area which are sequentially arranged according to a production technology. A plurality of mechanical arms used for conveying workpieces are arranged among the areas. The blank making area comprises a first heating furnace and a rollerforging machine. The die forging area comprises a second heating furnace and a die forging press machine set, the die forging press unit is used for forging forming of a blank obtained after secondary heating, and the workpieces are conveyed to the heat treatment area through the mechanical arms. The heat treatment area comprises a solution treatment furnace and a cooling device, the solution treatment furnace is used for carrying out solution treatment on the forged workpieces, the workpieces are conveyed to the cooling device through the mechanical arms, and a finished product bin is connected to a discharge port of the cooling device. The automobile control arm forging production line is reasonable in layout, high in automation degree and good in stability; the heat treatment area is additionally arranged, so that the production time is shortened, and the production efficiency is improved; and the heating process adopts jet flow heating, so that the heating speed and heating uniformity of the blank are improved, and the product quality is effectively improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment and automation, in particular to an automobile control arm forging production line and a forging forming process. Background technique [0002] The automobile control arm belongs to the connecting structure in the automobile chassis suspension system, and is a connecting piece used to connect the wheel hub and the sub-frame. As the guide and force transmission element of the automobile suspension system, the control arm transmits various forces acting on the wheels to the body, and at the same time ensures that the wheels move according to a certain trajectory. The control arm elastically connects the wheel and the vehicle body together through a ball joint or a bush respectively, so the control arm (including the bush and the ball joint connected thereto) should have sufficient rigidity, strength and service life. With the requirements of lightweight automobiles, iron con...
