Hand guarding device for open type press

Abstract

The invention provides a hand guarding device for an open type press. The hand guarding device comprises fixing bolts (1), a fixing plate (2), a screw (3), a transverse supporting plate (4), a glass baffle (5) and an adjusting nut (6). According to the principle of the hand guarding device, the glass baffle is additionally arranged between a die and an operator, the die is separated from the operator, the double hands of the operator cannot enter the region of the die, and a hand injury accident is avoided. The hand guarding device has the advantages that the position of the glass baffle can be adjusted according to the size of the press and the size and the height of the die, the hand guarding device has three-dimensional adjustability, is suitable for all dies of all open type presses, high in practicality, easy to popularize and convenient to maintain, has few faults, needs little ancillary work and has few constraints on the operator, the width of the baffle is larger than that of the die, the field of view is wide, and sight lines of the operator are not obstructed. The hand guarding device is simple in structure, reliable in performance and low in manufacturing cost, and no hole needs to be drilled in the press when the hand guarding device is installed.

Description

(1) Technical field [0001] The invention relates to a hand protection device for a press, in particular to a safety protection device suitable for an open press with simple structure, convenient operation, safety and reliability for protecting the hands of an operator, and belongs to the technical field of industrial production safety protection. (2) Background technology [0002] The open press is a kind of stamping equipment with a wide range of uses. It mainly uses steel plates as raw materials. It uses dies to punch some small-sized parts. It uses rigid clutches and band brakes. Stopping halfway, once the slider is started, it can no longer take risky operations. [0003] At present, most of the safety protection devices used for open presses fall into four categories: hand tools, mechanical devices, hands-combined devices, and photoelectric protection devices. They can only protect the operator when the control mechanism of the press and the clutch brake system are wor...

AI Technical Summary

Problems solved by technology

[0011] Since the open press cannot stop at the halfway position after starting, the photoelectric protection device can only guarantee that if the operator's hand reaches the mold area before the slider starts, the slider refuses to start, but if the operator's hand reaches the mold area before the slider starts, into the mold area

The photoelectric protection device will not be able to play a role. In addition, it is troublesome to debug and maintain the device, and the mold of the press is frequently disassembled, so it is difficult to popularize and use
