The operation process using the manual hydraulic bending apparatus is described below:
the process of descending and bending the piston is as follows: placing a plate 7 to be bent on a lower die 8, and turning a lifting switching handle 25 to the right to a descending position according to the direction indicated by an arrow in figure 3; then, the handle 11 is pressed down manually to enable the rotating shaft 13 to rotate, the rotating shaft 13 drives the shifting fork 14 to move, the plunger 15 is driven by the shifting fork 14 to move upwards to generate negative pressure, and hydraulic oil in the oil tank 17 is injected into a compression cavity P1 of the oil cylinder 1 through a hole passage T1 at the bottom of the guide shaft 18, the oil absorption one-way valve 26 and a compression hole passage P2 in sequence. The handle 11 is pulled upwards to move the plunger 15 downwards, so that hydraulic oil in a compression cavity P1 of the oil cylinder 1 is compressed, and the compressed hydraulic oil enters a rear cavity A2 of the oil cylinder 1 through a compression hole P2, an input port of the manual reversing valve 20, a port P of the manual reversing valve 20, a first oil injection one-way valve 27, an A1 port of the integrated valve plate 22 and a descending oil pipe 23 in sequence; the pilot port of the first pilot-controlled check valve 29 is subjected to oil pressure, the pilot port K1 of the pilot-controlled pilot two-position four-way reversing valve 19 is subjected to oil pressure, and oil in the front cavity B2 of the oil cylinder 1 sequentially flows into the oil tank 17 through the riser pipe 24, the port B1 of the integrated valve plate 22, the first pilot-controlled check valve 29, the port B of the pilot-controlled pilot two-position four-way reversing valve 19 and the port T of the pilot-controlled pilot two-position four-way reversing valve 19. The pressure of the compressed hydraulic oil in the rear cavity A2 of the oil cylinder 1 acts on a large area of the cavity A1 of the piston 2, so that the upper die 6 is driven to descend, and the extending force acts on the plate 7 to produce bending forming. If higher pressure is required, only the handle 11 needs to be pulled back and forth.
The lifting process of the piston after bending forming is as follows: firstly, the lifting switching handle 25 is pulled leftwards to the lifting position; the manual handle 11 is pressed down to drive the plunger 15 to move upwards through the shifting fork 14 to generate negative pressure, so that the hydraulic oil in the oil tank 17 is injected into the compression cavity P1 of the oil cylinder 1 through the oil suction one-way valve 26. The handle 11 is pulled upwards to drive the plunger 15 to move downwards through the shifting fork 14, so that the hydraulic oil in the compression cavity P1 of the oil cylinder 1 is compressed. Compressed hydraulic oil sequentially passes through a compression hole passage P2, an input port of the manual reversing valve 20 and the second oiling one-way valve 28 to enter a front cavity B2 of the oil cylinder 1, a pilot port of the second hydraulic control one-way valve 21 is subjected to oil pressure, a pilot port K2 of the hydraulic control pilot two-position four-way reversing valve 19 is subjected to oil pressure, and oil in a rear cavity A2 of the oil cylinder 1 sequentially passes through the descending oil pipe 23, an A1 port of the integrated valve plate 22, the second hydraulic control one-way valve 21, an a port of the hydraulic control pilot two-position four-way reversing valve 19 and a T port of the hydraulic control pilot two-position four-way reversing valve 19 to flow into. The pressure of the compressed hydraulic oil in the front cavity B2 acts on the circular area of the cavity B2 of the piston 2, so that the piston drives the upper die 6 to lift upwards, and then the bent and formed plate 7 is taken down. If higher pressure is required, only the handle 11 needs to be pulled back and forth.
In the standby state (the handle 11 is not moved), the hydraulic oil in the chambers a2 and B2 of the piston 2 is locked by the second pilot check valve 21 and the first pilot check valve 29, respectively, and the piston 2 is kept in the current locked state.
When the liquid level of the oil pointer 30 is seen to be at a low position, the oil filling screw plug 16 is firstly screwed off, hydraulic oil is filled into the oil tank 17, and the oil filling screw plug 16 is installed after the liquid level exceeds the high position of the oil pointer 30.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, as various modifications and variations will be apparent to those skilled in the art.
