Figure 2 and Figure 3 As shown, when the first swing arm 2 and the second swing arm 3 are opened in place, the first support rod 4 supports the hydraulic flanging machine to prevent abnormal phenomena such as aging of the hydraulic press equipment, poor sealing, oil leakage, sliding, or joint breakage and mold falling. The second support rod 5 supports the mold to prevent the mold from being pressed down.

[0032] The support and protection device of this embodiment, the fixed frame 1 can be fixed on a wall, etc., when it is necessary to support the hydraulic flanging machine and the mold, the first swing arm 2 is rotated and the second swing arm 3 is rotated, so that the first support rod 4 is moved to a position capable of supporting the hydraulic flanging machine, and the second support rod 5 is moved to a position supporting the mold. With this arrangement, there is no need for manual placement of the support rods, thereby reducing safety hazards.

[0033] As an alternative embodiment, see Figure 1-Figure 3As shown, the supporting and protecting device further comprises a first rotating cylinder 6, which is fixed on the fixing frame 1 and drivingly connected to the first swing arm 2, so as to drive the first swing arm 2 to rotate in a horizontal plane.

[0034] The first rotary cylinder 6 can drive the first swing arm 2 to open or close automatically without manual pushing or manually placing the support rod against the bottom of the hydraulic flanging machine, thereby reducing labor intensity and potential safety hazards.

[0035] As an optional embodiment, the supporting and protecting device further comprises a second rotating cylinder 7, which is fixed on the first supporting rod 4 and is drivingly connected to the second swing arm 3 for driving the first swing arm 2 to rotate in a horizontal plane.

[0036] The second rotary cylinder 7 can drive the second swing arm 3 to open or close automatically without manual pushing or manually pressing the support rod against the lower part of the mold, thereby reducing labor intensity and potential safety hazards.

A locking hole 9 is arranged on the second swing arm 3. When the first swing arm 2 and the second swing arm 3 are closed, the locking portion 13 can be inserted into the locking hole 9.

[0038] See also Figure 1 As shown, when there is no need to support the hydraulic flanging machine and the mold, that is, when the first swing arm 2 and the second swing arm 3 are closed, the locking portion 13 is inserted into the locking hole 9 of the second swing arm 3, so that the support and protection device remains in a closed state, which is convenient for storage, reduces space occupancy, and prevents the first swing arm 2 and the second swing arm 3 from being opened by mistake.

[0039] As an alternative embodiment, see Figure 1-Figure 3 As shown, a telescopic cylinder 8 is provided on the fixed frame 1 , the telescopic cylinder 8 is vertically arranged, and the locking portion 13 is fixed to the telescopic end of the telescopic cylinder 8 .

[0040] When the first swing arm 2 and the second swing arm 3 are closed, the locking portion 13 is inserted into the locking hole 9 of the second swing arm 3 under the drive of the telescopic cylinder 8, so that the support protection device remains in a closed state, without manual locking, thereby reducing labor intensity.

[0041] As an alternative embodiment, see Figure 1 As shown, the second swing arm 3 includes an upper swing arm and a lower swing arm, the upper swing arm and the lower swing arm are respectively connected to the upper and lower parts of the second support rod 5, one end of the upper swing arm is connected to the driving end of the second rotary cylinder 7, one end of the lower swing arm is rotatably connected to the first support rod 4, and the lock hole 9 is located on the lower swing arm.

The controller is electrically connected to the closing sensing switch 10 and the telescopic cylinder 8, and is used to control the telescopic cylinder 8 to extend when the second swing arm 3 is closed in place.

[0044] When the second swing arm 3 is closed, the first swing arm 2 is also in a closed state (otherwise the second swing arm 3 cannot be closed), and the closing sensing switch 10 transmits a signal to the controller, and the controller controls the telescopic cylinder 8 to extend. The locking part 13 is inserted into the locking hole 9 of the second swing arm 3 under the drive of the telescopic cylinder 8, so that the supporting protection device remains in a closed state, without manual locking, thereby reducing labor intensity.

[0045] As an alternative embodiment, see Figure 1-Figure 3 As shown, an opening sensing switch 11 is provided on the fixing frame 1, and the opening sensing switch is used to detect whether the first swing arm 2 is fully opened. The controller is electrically connected to the opening sensing switch and the second rotating cylinder 7, and is used to control the second rotating cylinder 7 to stop moving when the second swing arm 3 is fully opened.

[0046] See also Figure 2 and Figure 3 As shown, when the second swing arm 3 is fully opened, the first swing arm 2 is also fully opened (otherwise the second swing arm 3 cannot be fully opened), the sensing switch 11 is turned on to transmit the signal to the controller, and the controller controls the second rotary cylinder 7 and the first rotary cylinder 6 to stop moving, and the first support rod 4 and the second support rod 5 correspond to support the liquid flanging machine and the mold.

[0047] As an alternative embodiment, see Figure 1-Figure 3 As shown, the top end of the second support rod 5 is provided with an elastic buffer portion, which can play a buffering effect and prevent the mold from being damaged by collision.

[0048] See also Figure 1-Figure 3 As shown, the elastic buffer portion includes a buffer spring 12 .

[0049] The support and protection device of this embodiment is installed outside the working area of ​​the hydraulic flanging machine of the car door production line. When the first swing arm 2 and the second swing arm 3 are opened, the first support rod 4 and the second support rod 5 reach the hydraulic flanging machine and the car door flanging mold, and the support and protection device is used to support the hydraulic flanging machine and the car door flanging mold in a diagonal manner. Before work, when the employee enters the in-line working mode through the hydraulic flanging machine control console, the support and protection device automatically opens and swings out to the set position to achieve automatic protection measures.
