[0020] The following will describe in detail some embodiments of the present utility model with reference to the drawings.

[0021] A pressure machine protection baffle according to the present utility model includes a protection plate frame and a transparent baffle. The protection plate frame includes a widened eaves plate 1 and a front baffle 7. See the attached Figure 1 , both the widened eaves plate 1 and the front baffle 7 are made of steel and are cut from steel plates. The widened eaves plate 1 is in the shape of a slender rectangular strip, and the front baffle 7 is in the shape of a wide rectangular strip. The widened eaves plate 1 is welded to the upper and lower ends of the front baffle 7. The front baffle 7 can be made of an integral steel plate, and a window 10 is cut out in the middle. In order to save steel, it is preferably that the front baffle 7 is composed of two pieces, which are respectively welded on both sides, and a window 10 is reserved in the middle. See the attached Figure 2 .

[0022] The transparent baffle includes a front clamping plate frame 11, a rear clamping plate 3, and a transparent clamping plate 12. See the attached Figure 2。The front clamping plate frame 11 and the rear clamping plate 3 are also made of steel. The front clamping plate frame 11 is cut from a steel plate and then bent by sheet metal into a square shape. The rear clamping plate 3 is formed by cutting a steel plate. The transparent clamping plate 12 is made of a transparent material, such as polycarbonate, polymethyl methacrylate, etc., and preferably plexiglass. After processing, the transparent clamping plate 12 is placed between the front clamping plate frame 11 and the rear clamping plate 3. Through holes are opened at the border positions of the three components, and the three are fixed together with the screw and nut set 2.

[0023] The transparent baffle is arranged on one side of the protective plate frame. The axial dimension of the transparent baffle is slightly longer than that of the window 10 and covers the window 10. The transparent baffle is fixed to the protective plate frame by welding. Slider assemblies are arranged at both ends of the transparent baffle. The slider assembly includes a T-shaped slider 4. The T-shaped slider 4 is arranged on the widened eaves plate 1. The T-shaped slider 4 is used to cooperate with the reserved T-shaped groove of the press slider. An oval hole 6 is arranged on the widened eaves plate 1. The T-shaped slider 4 can axially move within the range defined by the oval hole 6. The slider assembly further includes support square tubes 8 arranged on the left and right sides of the transparent baffle. Both ends of the support square tube 8 abut against the widened eaves plate 1. The T-shaped slider 4 is connected to one end of the support square tube 8. For details, please refer to the appendix Figure 1 , a long bolt 5 is arranged in the support square tube 8. One end of the long bolt 5 is connected to the T-shaped slider 4, and the other end extends out of the support square tube 8, extends out from the oval hole 6 on the widened eaves plate 1 on the adjacent side, and is connected with a nut 9 at the bottom. The support square tube 8 can play a certain supporting role, making the structure of the protective plate frame more stable. After loosening the nut 9, the slider assembly can be axially moved as a whole.

[0024] The working principle of the present utility model is as follows: After all parts are connected, the T-shaped slider 4 is placed into the reserved T-shaped groove of the press slider, and the nut at the bottom is tightened to lock the T-shaped slider 4 to the press slider. The work of the press is usually realized by the reciprocating up and down movement of the slider. When pressing down, it is for applying pressure to work, and when rising, it is for resetting. When pressing down, the protective baffle will descend with the slider, separating the processing area from the operator; after the slider rises, the protective baffle will rise synchronously, opening the processing area, and employees can load and unload materials normally without additional actions, greatly improving the processing efficiency.

[0025] The present utility model is simple to install. It only needs to install the T-shaped slider 4 into the reserved T-shaped groove of the press slider and then lock the nut 9 at the bottom to complete the fixation. The T-shaped groove spacings of different press sliders are different, and the overall position of the slider assembly can be adjusted for adaptation, improving the scope of application. The whole is made of steel structure, and the middle light-transmitting part selects plexiglass material, which has good impact resistance and wear resistance, and good mechanical properties. It is not only convenient for the operator to observe the operation of the press in real time, but also can play a good buffer and protection effect in the case of workpiece flying out or workpiece fragments flying out during the operation of the press. Ordinary steel can be selected, the processing technology is simple, and bolts, nuts, etc. are conventional accessories, and the overall manufacturing cost is low.

[0026] The basic principles and advantages of the present utility model have been described above. For those skilled in the art, the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, after reading this specification, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features therein. Without departing from the concept of the present utility model, any obvious replacement is within the protection scope of the present utility model.
