Description

Technical Field

[0002] During the operation of the vehicle, in order to cushion the impact of severe road conditions on the wheels and reduce the strong vibrations caused by the impact, a wheel spring body is usually provided on the wheel. The wheel spring body is composed of a plurality of equal-length formed steel plates in a ring shape and is formed through preheating stamping, quenching, surface treatment and other processes.

[0003] However, the existing wheel spring body processing equipment has a simple structure and a single function. The entire forming process of the wheel spring body needs to be completed by multiple independent devices. For example, the product needs to be completed through multiple independent processes such as cutting, heating and annealing, stamping, quenching, tempering, shot peening, and assembly. The processing process requires the cooperation of multiple experienced operators, and the operation is difficult. Since the entire processing process is manually operated, it is very dangerous. Moreover, the operator needs to repeatedly heat and flip the wheel spring body during the stamping and forming process, which has low processing efficiency and unstable quality of the finished wheel spring body. After the steel plate is heated and annealed, the thickness of the surface decarburization layer increases and the fatigue strength decreases. The steel plate forming is completed manually, which has high labor intensity, low efficiency, and unstable product quality.

[0038] The heat treatment equipment in this embodiment is a quenching box 1, on which a loading group (not shown), a feeding assembly, a tank body, a quenching system 4 and a discharging assembly 5 are provided. The molding system 3 is arranged on the upper part of the quenching box 1, and the molding module 33 is arranged in the tank body.

[0039] like Figure 3 As shown, a forming lifting assembly 31 for changing the vertical displacement of the wheel spring body is provided on the upper part of the forming system 3 , and the axial displacement of the forming lifting assembly 31 is controlled by the PLC control system 6 .

[0040] There are two groups of forming and lifting components 3, and the two groups of forming and lifting components 3 are respectively arranged on both sides of the forming module 301. The two groups of forming and lifting components move synchronously to cooperate in completing the lifting or lowering action of the spring body. The forming system 3 includes a forming frame 36 arranged on the upper part of the quenching box. The bottom of the forming frame 36 is fixed to the ground by anchor screws. The forming frame 36 and the quenching box 1 are separate structures. A crossbeam 34 is arranged on the forming frame 36, and the two forming and lifting components are respectively fixedly connected to the crossbeam 34 of the forming frame 36.

[0041] In other embodiments, the number of lifting components may be other than the number of lifting components, such as four lifting components evenly distributed on the upper portion of the molding die. The present invention does not impose any limitation on the specific number.

[0042] like Figure 3 As shown, a forming heating induction load component 32 for heating the wheel spring body is also fixedly disposed in the forming system 3 , and the forming heating induction load component 32 is disposed between the forming system 3 and the forming lifting component 31 .

[0043] When it is necessary to heat the wheel spring body after forming, the wheel spring body is lifted to the top of the forming heating induction load assembly 32 through the forming lifting assembly 3, and the PLC control system 6, hydraulic system 7 and induction heating control system 8 are started to position and automatically heat the wheel spring body. When heated to the preset temperature, the wheel spring body is quickly lifted to the forming module 33 for forming. After forming, the wheel spring body is lowered to the feeding assembly 2 through the forming lifting assembly 3, and the lifting assembly 3 is returned to its position. The feeding assembly 2 moves the formed wheel spring body to the quenching system for quenching treatment, or other heat treatment methods required by the process for subsequent processing. The induction heating control system 8 is provided with an insulated gate transistor (IGBT) module, which has a fast heating speed. The temperature of the wheel spring body can be heated to the preset temperature in a short time, shortening the heating time and improving the economic benefits.

[0051] The inner forming module 304 is engaged with the inclined surface of the central forming tightening mechanism 305. When the central forming tightening mechanism 305 contracts, the inner forming module 304 is radially dispersed and positioned in an annular manner. First, four cylinders extend to support the wheel spring body, and the pressure on the wheel spring body reaches pressure N1. The other cylinders extend synchronously to reach pressure N1. The 12 cylinders are pressurized to N2 synchronously and maintained for a certain time T.

The conveying device 52 moves slowly to allow the wheel spring body to cool naturally. After the wheel spring body cools naturally, it is automatically transported to the receiving area.

After the lifting component 31 returns to its position, the mobile platform 2 moves the formed wheel spring body to the quenching system 4 at the end for quenching treatment.

[0060] Step three, the mobile platform 2 transfers the formed wheel spring body to the medium frequency quenching system 4, the quenching lifting component 41 of the medium frequency quenching system 4 lifts the wheel spring body to the quenching heating induction load component 43, and the wheel spring body is automatically heated by the PLC electronic control system 6, the hydraulic system 7 and the induction heating control system 8. After being heated to the preset temperature t, it is quickly lowered to the quenching liquid in the quenching box 1 for quenching. After the quenching is completed, the quenching lifting component 41 lifts the wheel spring body to the discharge component 5.

[0061] Step 4: The discharging assembly 5 includes a discharging bracket 51 and a feeding device 52 installed on the discharging bracket 51. The wheel spring body after quenching is transported to the receiving area through the discharging conveying device 52. The conveying device 52 moves slowly to allow the residual heat of the wheel spring body to cool naturally, and the wheel spring body is automatically transported to the receiving area after it cools naturally.
