Safety protection device of four-column plane cutting machine

Abstract

The utility model discloses a safety protection device of a four-column plane cutting machine. The safety protection device comprises a cutting machine body and a safety protection assembly. According to the safety protection device of the four-column plane cutting machine, when the working plate on the cutting machine body moves inwards along the sliding rails to conduct cutting operation, the toothed plate at the outer end of the right sliding base on one side of the working plate can drive the gear and the lead screw to rotate in the inwards-moving process, and therefore the working plate can rotate through the rotating lead screw; the protective plates in the sliding grooves in the two sides of the front end of the cutting machine body are driven to move downwards so that the protective plates in the sliding grooves can move downwards to the upper end of the working plate after the working plate moves to the rearmost end, and therefore the situation that a worker moves the hand into the cutting machine body and forgets to withdraw the working plate when moving the working plate, and dangerous accidents are caused is avoided. And when the worker forgets to retract the arm after moving the working plate, the rubber plate at the bottom of the protection plate flexibly presses the arm of the worker, and then the arm of the worker is prevented from being injured.

It is to be explained that the embodiment of the utility model and the feature in the embodiment can be combined mutually in the case of not conflicting.

[0025] Some embodiments of the utility model provide a kind of safety guard of four-column planar cutting machine described below in conjunction with the drawings.

[0026] Embodiment one:

[0027] In conjunction with Figures 1-5 The utility model provides a kind of safety guard of four-column planar cutting machine, including: cutting machine body 100, safety guard component 200;Cutting machine body 100 includes the upper pressing plate 101 of its top installation;Safety guard component 200 includes the slide rail 201 of both sides fixed installation on cutting machine body 100, the left slide seat 202 and right slide seat 203 of respectively movable installation on both sides slide rail 201, the work plate 204 of left slide seat 202 and right slide seat 203 top fixed installation, the toothed plate 205 of right slide seat 203 outer side fixed installation, the gear 206 of toothed plate 205 outer side meshing installation, the lead screw 207 of gear 206 middle fixed installation, the protective plate 208 of lead screw 207 outer end movable installation, protective plate 208 lower part is also fixedly installed with rubber plate 209, protective plate 208 top side is also fixedly installed with lead screw sliding block 210, and lead screw sliding block 210 is installed in the outer end of lead screw 207, cutting machine body 100 front end both sides are also evenly provided with the sliding slot 211, and protective plate 208 movable installation is in the sliding slot 211, lead screw 207 top is also fixedly installed with the stop block 212, one side in protective plate 208 is also through the installation hole 213 being provided with, and lead screw 207 is in installation hole 213, lead screw 207 bottom is also movablely installed with the fixed seat 214, and the fixed seat 214 bottom is fixed on cutting machine body 100.

[0028] Specifically, the four-column planar cutting machine is also commonly known as a hydraulic precision four-column cutting machine, which is a cutting equipment widely used in industrial production; when the workbench 204 on the cutting machine body 100 moves inward along the slide rail 201 to perform cutting operation, the tooth plate 205 at the outer end of the right slide seat 203 on one side of the workbench 204 can drive the gear 206 and the lead screw 207 on the outer side to rotate during inward movement, so that the rotating lead screw 207 drives the protective plate 208 in the slide groove 211 on both sides of the front end of the cutting machine body 100 to move downward, so that after the workbench 204 moves inward to the last end, the protective plate 208 in the slide groove 211 moves downward to the upper end of the workbench 204, thereby avoiding the danger caused by the staff moving the workbench 204 and forgetting to retract the hand into the cutting machine body 100, thereby effectively and significantly protecting the staff, and when the staff moves the workbench 204 and forgets to retract the arm, the downward protective plate 208 can also flexibly press the staff's arm through the rubber plate 209 at the bottom of the protective plate 208, thereby avoiding injury to the staff's arm in the process of forgetting to retract the arm, the long-stroke lead screw 207 arranged at the upper end of the gear 206 can also make the protective plate 208 on the lead screw 207 lift to a certain height after the workbench 204 is pulled back in a short distance, thereby avoiding the protective plate 208 with a short lifting stroke from blocking the cutting object at the upper end of the workbench 204 when the workbench 204 is pulled back, the lead screw block 210 mounted on one side of the protective plate 208 is mainly used for lifting and adjusting the protective plate 208 through the forward and reverse rotation of the lead screw 207, the slide groove 211 on both sides of the front end of the cutting machine body 100 can bind the movement of the protective plate 208, the stop block 212 at the top of the lead screw 207 is mainly used to prevent the lead screw block 210 from being separated from the lead screw 207, and the fixing seat 214 mounted at the bottom of the lead screw 207 is mainly used to ensure the stability of the rotation of the gear 206 and the lead screw 207.

[0029] The working principle and use process of the utility model are as follows:

[0030] When the staff performs cutting operation by pushing the workbench 204 inward along the slide rail 201, the tooth plate 205 at the outer end of the right slide seat 203 on one side of the workbench 204 will drive the gear 206 and the lead screw 207 on the outer side to rotate in the opposite direction during inward movement, and after the lead screw 207 rotates in the opposite direction, the lead screw block 210 at the upper end of the lead screw 207 will drive the protective plate 208 to move downward along the lead screw 207 in the slide groove 211 on both sides, so that the protective plate 208 moves downward to the upper part outside the workbench 204 along with the movement of the workbench 204 to the tail end of the slide rail 201, thereby blocking the gap between the front end of the cutting machine body 100 and the upper pressing plate 101 to avoid the problem that the staff's arm is continuously in the gap between the front end of the cutting machine body 100 and the upper pressing plate 101 when pushing the workbench 204 inward, and is injured after the cutting machine body 100 is started.

[0031] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
