Embodiment
[0018] As shown Figure 1 in the figure, a single-arm hydraulic press includes a base 1, and a pressure plate 2 and a power distribution driving part 3 which are located on the upper side of the base 1 and are machined to match each other. Among them, a processing stroke cavity 31 is formed between the pressure plate 2 and the power distribution driving part 3. During the driving operation of the power distribution driving part 3, the workpiece to be processed placed on the pressure plate 2 is completed by hydraulic processing of the power distribution driving part 3.
[0019] It should be mentioned that, in order to effectively prevent the safety risks caused by the close-range operation of the staff during the operation, such as the flying debris generated by the impact of the workpiece and the impact injury of the limbs, a protective net structure 5 is provided on one side of the outer periphery of the processing stroke cavity 31, and the power distribution driving part 3 is connected with a rocker arm. A moving control board 4 is connected to the rocker arm, and the moving control board 4 is used to control the operation of the power distribution driving part 3. Therefore, when the situation of flying debris occurs, effective shielding is achieved through the protective net structure 5, and the impact injury of the staff's limbs caused by the accidental entry of the staff's limbs into the processing stroke cavity 31 is effectively avoided.
[0020] As shown Figure 1 、 Figure 2 in the figure, the pressure plate 2 is a U-shaped long-axis pressing tooling plate. A long-axis pressing groove 21 is provided at the front end of the U-shaped long-axis pressing tooling plate, and the base 1 is provided with a matching leakage cavity 11 that matches the long-axis pressing groove 21 up and down, so that the combination of the U-shaped long-axis pressing tooling plate and the base 1 with the matching leakage cavity 11 is suitable for the hydraulic processing of the long axis.
[0021] Among them, in order to stably and conveniently control the moving control board 4 in the embodiment of the present application, the rocker arm includes a connecting seat 44 fixedly connected to the power distribution driving part 3. A short swing arm 43 is rotatably connected to the front and back of the connecting seat 44, and a long swing arm 42 is rotatably connected to the front and back of the end of the short swing arm 43 away from the connecting seat 44. The long swing arm 42 is fixedly connected with a connecting drooping arm 41, and the connecting drooping arm 41 is connected to the moving control board 4. It should be noted that a paired rotating elbow 422 rotatably connected to the short swing arm 43 front and back and a vertical connecting elbow 421 fixedly connected to the connecting drooping arm 41 are respectively provided at both ends of the long swing arm 42, and both the vertical connecting elbow 421 and the paired rotating elbow 422 are at a 90° bend angle. Correspondingly, the connecting seat 44 and the short swing arm 43 are rotatably connected through the paired rotating elbow 422. Among them, the upper side of the connecting seat 44 is rotatably connected to the paired rotating elbow 422 with both ends facing downwards, the axis of the connecting drooping arm 41 is vertically distributed, and the moving control board 4 is universally connected to the lower end of the connecting drooping arm 41. Therefore, when operating the moving control board 4, it is suitable to control the planar linear movement of the moving control board 4 at a set height position, and then the effective adjustment in the up, down, left and right directions of the orientation is realized through the universal connection structure.
[0022] To achieve the height adjustment of the mobile control panel 4, the connecting drooping arm 41 in the embodiments of the present application is a telescopic arm, so that the height of the mobile control panel 4 can be adjusted by adjusting the length through telescoping, to meet the needs of people with different heights.
[0023] As Figure 1 , Figure 2 , Figure 3 shown, the protective net structure 5 includes side partition nets 52 on both sides, a front partition net 51 above the front side, and a rear partition net 53 at the rear. A lock 521 for switching is provided at the front end of the side partition net 52, and a hinge 522 is provided at the rear end. The lower side of the front partition net 51 is hollowed out for feeding and discharging. At the same time, a heat dissipation rear plate 12 is provided at the rear side of the base 1 and the power distribution driving part 3. The side partition net 52 has the function of opening and closing for adjusting the power distribution driving part 3. In the embodiments of the present application, both ends of the front partition net 51 are connected with telescopic cylinders to realize the lifting movement of the front partition net 51 through the telescopic cylinders. In order to improve the movement stability of the front partition net 51, guiding and limiting tracks are provided on both sides of the front partition net 51. Embodiment
