DETAILED DESCRIPTION

[0020] Reference Figures 1 to 5 The embodiments of the utility model are further described.

[0021] A protective device for a hydraulic press comprises a workbench 1, a hydraulic press body 2, a protective device and a locking member 7. The hydraulic press body 2 is placed on the workbench 1, the protective device is movably connected to the workbench 1, and the locking member 7 is placed on the protective device.

[0022] The protective device includes a first baffle plate 31, a second baffle plate 32, a handle 33, a buffer block 34, a first sealing strip 35 and a second sealing strip 36. The workbench 1 is provided with a first arc groove 4 and a second arc groove 5 which are connected to each other. The first arc groove 4 and the second arc groove 5 are respectively fixed with the first sealing strip 35 and the second sealing strip 36. The first sealing strip 35 and the second sealing strip 36 are both provided with an opening 6. The first baffle plate 31 and the second baffle plate 32 respectively pass through the openings 6 on the first sealing strip 35 and the second sealing strip 36 and extend into the first arc groove 4 and the second arc groove 5 to slide. The handle 33 is respectively fixed on the first baffle plate 31 and the second baffle plate 32. Two buffer blocks 34 are provided and are respectively fixed on the first baffle plate 31 and the second baffle plate 32. The first baffle plate 31 and the second baffle plate 32 are respectively embedded with an observation window 14.

[0023] By grasping the handle 33, the first baffle plate 31 and the second baffle plate 32 are respectively slid in the first arc groove 4 and the second arc groove 5 until the first baffle plate 31 and the second baffle plate 32 collide with each other, and then the first baffle plate 31 and the second baffle plate 32 are blocked in front of the staff, so that the debris splashed out when the hydraulic press processes the workpiece is blocked by the first baffle plate 31 and the second baffle plate 32, so as to avoid the waste chips on the surface of the workpiece splashing on the surrounding staff when the workpiece is worked, causing harm to the staff.

[0024] At the same time, by providing a buffer pad, the first baffle plate 31 and the second baffle plate 32 are moved by the handle 33, and then the first baffle plate 31 and the second baffle plate 32 drive the buffer pad to move until the buffer pads on the first baffle plate 31 and the second baffle plate 32 respectively contact the inner walls of the first arc groove 4 and the second arc groove 5, thereby achieving a buffering effect.

[0025] At the same time, by providing the first sealing strip 35 and the second sealing strip 36, it is difficult for debris generated by the hydraulic press body 2 during operation to enter the first arc groove 4 and the second arc groove 5.

[0026] At the same time, by providing the observation window 14, the hydraulic working process of the hydraulic press body 2 on the workpiece can be observed.

[0027] The inner walls of the first arc groove 4 and the second arc groove 5 are both provided with a slide groove 12, and both sides of the first baffle plate 31 and the second baffle plate 32 are provided with a slider 13, and the slider 13 is placed in the slide groove 12 to slide;

[0028] By providing a slider 13, when the first baffle 31 and the second baffle 32 slide in the first arc groove 4 and the second arc groove 5 respectively, the first baffle 31 and the second baffle 32 drive the slider 13 on the first baffle 31 and the second baffle 32 to move in the slide groove 12, thereby playing a guiding role, so that the first baffle 31 and the second baffle 32 can slide more stably in the first arc groove 4 and the second arc groove 5.

[0029] The locking member 7 includes a first limiting block 71, a second limiting block 72 and a bolt 73. The first limiting block 71 is fixed to the first baffle 31, and the second limiting block 72 is fixed to the second baffle 32. The first limiting block 71 is provided with a threaded hole 8, and the second limiting block 72 is provided with a connecting hole 9. The bolt 73 passes through the connecting hole 9 and is threadedly connected to the threaded hole 8.

[0030] When the first baffle 31 and the second baffle 32 come into conflict with each other, the bolt 73 is rotated so that the bolt 73 passes through the connecting hole 9 and is threadedly connected to the threaded hole 8, thereby fixing the first baffle 31 and the second baffle 32, thereby preventing the debris splashed out by the hydraulic press body 2 when working on the workpiece from flowing out through the gap at the connection between the first baffle 31 and the second baffle 32, thereby causing harm to the staff.

[0031] A first magnetic strip 10 is formed on the first baffle plate 31, and a second magnet corresponding to the first magnetic strip 10 is embedded in the second baffle plate 32, so that the first magnetic strip 10 and the second magnetic strip 11 are attracted to each other;

[0032] The first magnetic strip 10 and the second magnetic strip 11 are attracted to each other, thereby further strengthening the fixation between the first baffle plate 31 and the second baffle plate 32 .

[0033] Working principle: first, place the workpiece to be processed on the workbench 1, and then pull the handle 33 on the first baffle 31 and the second baffle 32, so that the handle 33 drives the first baffle 31 and the second baffle 32 to slide in the first arc groove 4 and the second arc groove 5 respectively, until the first baffle 31 and the second baffle 32 conflict with each other and the first magnetic strip 10 and the second magnetic strip 11 are adsorbed on each other, and then the bolt 73 is passed through the connecting hole 9 on the second limit block 72 and threadedly connected with the threaded hole 8 on the first limit block 71, thereby fixing the first baffle 31 and the second baffle 32, and finally starting the hydraulic press body 2 to process the workpiece on the workbench 1, and observing the processing status of the workpiece through the observation window 14.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
