As the utility model discloses an optimal setting, the through-hole inner wall is fixed with the rubber circle.
As the utility model discloses an optimal setting, clamp plate and protective sleeve contact surface are provided with rubber buffer pad.
As the utility model discloses an it sets up to prefer, be provided with the cushion rubber circle on the terminal surface of protective sleeve open end.
The utility model discloses possess following beneficial effect:
the utility model discloses simple structure, reasonable in design, when the operation, a protective sleeve section of thick bamboo can drop in advance in the piston rod, and the staff has time to react, takes the hand out from the workstation, and simultaneously from because misoperation, when leading to the work piece to be pressed and explode, a protective sleeve section of thick bamboo also can prevent effectively that broken work piece from collapsing out and causing the injured condition of personnel to take place.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a protective hydraulic machine comprises a C-shaped frame 1, wherein a working platform 2 and a workpiece placing table 3 are arranged on the C-shaped frame 1, the workpiece placing table 3 is mounted at the upper end of the working platform 2, a hydraulic cylinder 4 is arranged at the top of the C-shaped frame 1, a piston rod 5 of the hydraulic cylinder 4 vertically faces the workpiece placing table 3, and a pressing plate 6 is fixedly connected to the tail end of the piston rod 5; still include the protection sleeve 7, protection sleeve 7 opening is down, and its up end middle part is provided with the through-hole, protection sleeve 7 is located through the through-hole cover on the piston rod 5, clamp plate 6 is located in protection sleeve 7, just 6 diameters of clamp plate are greater than the through-hole diameter, protection sleeve 7 diameters are greater than 2 diameters of operation platform.
As the preferred setting of the embodiment of the utility model, further, the through-hole inner wall is fixed with rubber circle 8.
As the preferred setting of the embodiment of the utility model, further, clamp plate 6 and protective sleeve 7 contact surface are provided with rubber cushion pad 9.
As the preferred setting of the embodiment of the utility model, further, be provided with the cushion rubber circle 10 on the terminal surface of the open end of the protection sleeve 7.
The working principle is as follows: in this embodiment, the protecting sleeve 7 is sleeved on the piston rod 5, due to the action of gravity, the protecting sleeve 7 can fall down to abut against the pressing plate 6, the piston rod 5 drives the pressing plate 6 to move down in the operation process of the hydraulic cylinder 4, due to the action of gravity, the protecting sleeve 7 synchronously moves down, and after the opening end of the protecting sleeve 7 abuts against the C-shaped frame, the piston rod 5 further drives the pressing plate 6 to move down to perform processing operation; after the workpiece is finished, the piston rod 5 moves upwards to drive the pressing plate 6, the protecting sleeve 7 is further driven to move upwards, and the protecting sleeve 7 moves upwards to have a certain distance with the operation platform 2 so as to be convenient for loading and unloading. The rubber ring 8 reduces friction between the piston rod 5 and the protective sleeve 7, and the buffer rubber pads 9 and the buffer rubber rings 10 reduce impact force between the protective sleeve 7 and the pressing plate 6 and between the protective sleeve and the C-shaped frame 1, so that shaking and noise caused by impact are reduced.
When the workpiece is pressed and exploded due to improper operation, the protective sleeve 7 can effectively prevent the broken workpiece from being burst out to cause injury to people. Meanwhile, when the automatic drawing machine runs, the protective sleeve 7 can descend in advance of the piston rod 5, so that a worker has time to react and draw out hands from the workbench.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "disposed," "connected," "fixed," "screwed" and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.
Furthermore, those skilled in the art will appreciate that while some embodiments described herein include some features included in other embodiments, rather than other features, combinations of features of different embodiments are meant to be within the scope of the invention and form different embodiments. For example, in the claims above, any of the claimed embodiments may be used in any combination.
