Description
Technical field
The present invention relates to a kind of punching machine safety device.
Background technology
Existing punch press must impose power to the workbench of place work piece, and the operator will put and the position adjustment workpiece, does not therefore have the punch press of protector, and very easily the drift that is descended is at a high speed cut pressure and sustained a severe injury.In order to solve above-mentioned safety problem, people have been installed safety device additional on punch press, yet general safety device is the stop device that punch press is set, as stop switch, punch press switch by photo-electric control etc., but only control the punch press switch and often do not reach ideal effect and since punch press high speed inertia, also need have a bigger punch press brake apparatus just can reach the security protection effect.Someone has invented hand protector, as application number is 99243324, the applying date is on September 20th, 1999, denomination of invention is the patent application of a kind of punch press with hand protector, mainly constitute by switch, the poker device of controlling its work by switch, poker device is fixed in punch press workbench side, switch can be arranged on punch press pedal above, also can be arranged on punch press pedal below, the position of switch is to set like this, when the punch press pedal down moves but before also not touching the punch ram switch, switch is touched.This patent adopts the poker device that installs additional by switch control, can set the motion formula of punch press, equal in process, to have added the hand preface one, the follow procedure operation can be played certain protection, but cause the reduction of operating efficiency, and the operator controls bad coordination to the interlock between switch and the pedal, and the action that drift dashes poker device down at a high speed also has influence.
Summary of the invention
Purpose of the present invention provides a kind of simple in structure, the punch press hand guard device that can operate automatically by sensor, the safe operation reliability is high in order to solve above-mentioned deficiency exactly.
The present invention realizes above-mentioned purpose by following technical proposals:
The hand guard device of punch press of the present invention comprises and dials hand lever, is provided with tooth bar in the stationary part of punch press, dials hand lever and is arranged on the turning cylinder and is positioned at centre position, punch press motion portion outside portion, between tooth bar and the turning cylinder transmission device is set; It is characterized in that: described transmission device is connected with electromagnet, and described punch press workbench both sides are provided with photoelectric sensor, and punch press one side is provided with auxiliary reclay, is electrically connected with the electromagnetic switch of electromagnet.
Described transmission device is for being provided with travelling gear formation being provided with on the turning cylinder between gear, tooth bar and the turning cylinder gear; Described travelling gear is connected with electromagnet, is provided with a spring between electromagnet and the travelling gear; Described travelling gear is arranged on punch press motion portion's outboard rack and dials position between the hand lever, and is parallel with turning cylinder.
Described punch press also comprises floor push, and the one stroke switch is set on the connecting rod of floor push, and travel switch is connected between photoelectric sensor and the auxiliary reclay.
The invention has the advantages that:
Adopt photoelectric sensing to combine with mechanical linkage, mechanical ram and tooth bar move back and forth, intermediate drive gear at drift connects with electromagnet, during the electromagnet energising, travelling gear and running part from, when drift falls, in the drift dial that hand lever raises not can transmission, influence work with regard to can often not being subjected to dial the hand lever transmission when workman operates punch press, when drift glides, operating personnel's hand is also in the grinding tool scope, and photoelectric sensor can be with the dump of electromagnet, by spring with intermediate drive gear to pressing down, and with the interlock of tooth bar idler gear, make and dial hand lever, push hand aside the security protection effect of playing, effectively avoid accident to take place fast to setting aside; Photoelectric sensor is ceaselessly monitored in addition, and auxiliary reclay can be controlled photoelectric sensor work, can protect the service life of photoelectric sensor.
