Description

1 The invention relates to mechanical engineering, in particular to safety devices for presses. A device for removing the operator’s hands from the working area of the press and its fence is known, comprising a housing articulated with the press cover and a protective screen in the form of two shields, at least one of which is made adjacent to the axes, secured in the housing l However, the known device does not have good enough safety conditions. The purpose of the invention is to improve the safety conditions. This goal is achieved by the fact that in the device for removal of the operator's hands from the working area of the press and its fencing, comprising a housing coupled to the press casing and a protective screen in the form of two-shield, at least one of which is driven; can be rotated on the axes fixed in the body articulated with the casing, another of the said guards — also the driven body is placed between the press bed and the casing, and the axes in the body are perpendicular to the front of the press. FIG. 1 schematically shows the proposed device, a general view; in fig. 2 shows a section A -A in FIG. 1. The device contains a protective screen in the form of two flaps 1 and 2 mounted on axes 3 and k fixed in the housing 5. articulated with the casing 6. The elastic elements are fixed on the flaps 1 and 2 The flaps drive T and 2 are designed as a power cylinder. 8 and trapezoidal cable 9, connected to the piston rod 10 of the power cylinder 8. On the flaps 1 and 2, the fingers 11 are secured in the grooves 12, made in the trapezoidal t 9; The housing 5 is installed between the press bed (not shown) and a casing 6. The axes 3 and are mounted in the housing 5 perpendicular to the front of the press, and the flaps 1 and 2 are installed with the possibility of rotation in a plane parallel to the front of the press. A spring 13 is installed between the stockpile of the 10.force cylinder 8. Spacers 14 and 15 are fixed to the housing 5 and the trapezoidal rod 9, for guiding and cleaning the flaps 1 and 2 as they move. On the piston rod 10, fasten: flax flag 16, and on the case from a 1-cylinder 8 cylinder - limit switch. The device operates as follows. In the initial position, the cavity 18 of the power cylinder 8 is connected to the atmosphere, the piston rod 10 under the action of the spring 13 is in the upper position, and the flaps 1 and 2 are raised. When the operator is commanded to turn on the press, the compressed air is fed into the cavity 18 of the power cylinder 8, while the piston rod 10 is lowered down, compresses the spring 13 and deploys the flaps 1 and 2 around the axes 3 and A through trapezoidal traction 9 10, corresponding to the rotation of the flaps 1 and 2 at an angle of 90 °, the flag 16 acts on the switch 17, which gives the command to turn on the press clutch (not shown). If the operator’s hand is in the working area, then the flaps 1 and 2, in contact with it through the elastic elements 7, move it left or right from the working area of the press to the left or right. If there is a foreign object in the working area whose resistance the flaps 1 and .2 cannot overcome, then the piston-piston 10 is not allowed to go to its lowest position, and the switch 17 does not turn off, therefore, the press clutch does not turn on. When the slider performs one stroke, a command is given to shut off the press, the cavity 18 of the power cylinder 8 is connected to the atmosphere, and the spring 13 returns the flaps 1 and 2 to their original position. . The technical and economic effect of the implementation of the invention is provided by improving the safety conditions when working on the press in comparison with the prototype.
