Description
Technical field
The utility model relates to a kind of punch press safety installations, particularly a kind of safety lever of punch.
Background technique
Along with developing rapidly of China's industry, the use of punch press is more widespread, because the especially processing of multi-varieties and small-batch in course of working, great majority are manually-operable, punch press in use, often cause various industrial accidents because safety installations is not in place, and at present punch press with safety installations with the most use be photoelectric safety device, it is more that this safety installations is used in Pressespneumatic.And seldom use in mechanical press because this device is to be switched on or switched off clutch between control punch press drift bent axle and the drive wheel by photoelectric induction device and the electrical signal of break works, if the Security of punch press is to occur in the machinery of the clutch of control drift bent axle motion and break partly, photoelectric induction device is inoperative so.And clutch is higher with the mechanical failure incidence rate of the relative Pressespneumatic of break on the mechanical punch.And electrical equipment control is more weak, and the relative punch press of expense itself value that is modified to the photoelectric safety device generation is very big, and safe effect is bad, especially at the domestic machinery punch press.
Summary of the invention
In order to remedy above deficiency, the utility model provides a kind of safety lever of punch, and this safety lever of punch is simple in structure, and is easy for installation, uses reliably, can effectively avoid the generation of industrial accident.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of safety lever of punch, comprise lever, first rope, second rope and the pulley, to use direction to be benchmark, the first rope lower end is fixed positioned on the mold and punching head, fixedly connected with lever one end in the first rope upper end, lever is provided with a fulcrum, lever can rotate around this fulcrum, the lever the other end is connected with two second the other ends of restricting respectively, two second ropes are walked around two pulleys respectively and are turned to, second rope, one end is respectively equipped with lasso trick, and lasso trick can be placed on staff's the work finger, and pulley position is fixed.In use, the lasso trick of second rope is enclosed within on staff's the middle finger, when the drift of punch press upwards lifts, (below be as the criterion with this direction of observation) owing to take place clockwise greater than connecting first rope one end around support end with the second end weight that is connected of rope and rotate in lever, this moment, staff's hand can be with second rope will need product processed just to place the drift below to the motion of drift below, when drift moves downward will finish press work the time, the drift band first rope and is moved downward, lever one end is subjected to the pulling force of first rope and is rotated counterclockwise around fulcrum, thereby the second rope the other end is pulled upwardly, the hand that the end of restricting this moment second then will overlap the staff of lasso trick outwards is pulled out to the drift outside, thereby the hand that guarantees the staff can be by drift towards hindering.
As further improvement of the utility model, the lever and first end that be connected of rope to the distance of fulcrum less than the distance of the lever the other end to fulcrum, like this, drift has less action second rope just to have bigger action, can effectively guarantee drift sweep away before staff's hand gone out by second rope band.
As further improvement of the utility model, the lever the other end is provided with cross bar, and the cross bar both sides are connected with one second rope respectively.
As further improvement of the utility model, the cross bar two ends on the lever are symmetrical distribution.
As further improvement of the utility model, be provided with a fixing rod, pulley is rotatable to be fixedly arranged on the fixing rod the other end, and fixing rod one end is fixedly arranged on the outer side wall of punch press lower end.
As further improvement of the utility model, first rope is steel cable, because the pulling force of drift is bigger, uses steel cable safer, more reliable, long service life.
As further improvement of the utility model, second rope is for the rope made of hemp, and the rope made of hemp is soft tough, and is also durable when can not damage staff's finger.
As further improvement of the utility model, the fulcrum of lever is a supporting frame, and supporting frame one end is fixedly arranged on the punch press upside, and the supporting frame the other end and lever are articulated and connected.
Useful technique effect of the present utility model is: under the drift of punch press towards the time can drive lever and rotate counterclockwise around fulcrum, thereby driving the rope made of hemp slides around pulley, smoothly staff's hand is taken out of the drift outside, effectively avoided the generation of staff's industrial injury, and this mechanism can be installed on any punch press, need not any power and just can use, simple in structure, easy to operate, use reliable.
