DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] As Figures 1-4The utility model provides a technical scheme: a kind of electric screw press protection device, including rack 1, control box 2, grating 3, lower mould 4, switch box 5, upper mould 6, threaded sleeve 7, sliding block 8, slide rail 9, angle iron 10, proximity switch 11, servo motor 12, belt pulley 13, threaded rod 14, belt 15, fixed screw 16, emergency stop button 17, start button 18, base 19, rack 1 bottom is fixedly installed with lower mould 4, and lower mould 4 top is fixedly installed with angle iron 10, and angle iron 10 side is fixedly installed with proximity switch 11, and rack 1 front side and rear side are fixedly installed with grating 3, and rack 1 front side's left and right sides are fixedly installed with switch box 5.

[0021] Further, the inside both sides of rack 1 are fixedly installed with slide rail 9, and the outside of slide rail 9 is slidably connected with sliding block 8, and the outside of sliding block 8 is fixedly installed with upper mould 6.

[0022] Specifically, the structure of sliding block 8 and slide rail 9 can keep upper mould 6 moving up and down in vertical direction, reducing the error during forging.

[0023] Further, the right side of rack 1 is provided with control box 2, and the front side of control box 2 is provided with emergency stop button 17.

[0024] Specifically, when an emergency occurs, the operator can quickly press the emergency stop button 17, which will make the device stop running immediately, thereby ensuring the safety of the operator.
