Abstract
The utility model discloses a punch press with a hand protection device. the punch press comprises a punch and a work table which is arranged below the punch and used for a workpiece to be placed on, a check block is arranged on one side of the work table and driven by a cylinder, the cylinder is connected with a control device, the work table is provided with a photoelectric sensor which is used for detecting the hands of operation staff, and the photoelectric sensor is connected with the control device. When the punch is pressed down, if the photoelectric sensor detects the hands of the operation staff are still placed between the punch and the work table, signals are given out to the control device, the control device controls the cylinder to push the check block to enter the position between the punch and work table, so that the punch is blocked by the check block and can not continue to go downwards, and therefore the hands of the operation staff are prevented from being damaged.
Description
Technical field
The utility model relates to a kind of punch press.
Background technology
Punch press is processed by the workpiece that is pressed under the drift on the workbench, generally need the workman below drift, to carry out the placement of workpiece and the adjusting of the location of workpiece, this mode is as easy as rolling off a log to appear at drift when descending, and operating personnel's hand also at the drift downside, causes industrial accident.Therefore have at punch press optoelectronic switch is set, control the stop switch of drift by optoelectronic switch and since drift when descending speed be exceedingly fast, so inertia is very large.Therefore only depend on the stop switch of closing punch press to be difficult to the effect that reaches desirable.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of punch press with hand guard device, can protect operating personnel to the punch press misoperation time, and protection operating personnel's hand is not subject to the injury of drift.
The utility model is achieved through the following technical solutions: a kind of punch press with hand guard device, comprise drift and the workbench that is used for place work piece that below described drift, arranges, side at described workbench is provided with block, described block is by an air cylinder driven, described cylinder with is connected control device and connects, be provided with photoelectric sensor for detection of operating personnel's hand at described workbench, described photoelectric sensor be connected control device and connect, when drift presses down, if the hand that photoelectric sensor detects operating personnel is still between drift and work top the time, then send signal to control device, the promotion block enters between drift below and the workbench control device control cylinder so that cylinder is exerted oneself, so that drift blocked by block, can't continue descendingly, therefore guaranteed that operating personnel's hand does not come to harm.
In the technique scheme, the thickness of described block is between 10cm ~ 15cm.
The utlity model has following beneficial effect: when drift presses down, if the descending operating personnel's of being of drift hand still be positioned at drift below, then the promotion block enters between drift below and the workbench control device control cylinder so that cylinder is exerted oneself, so that drift is blocked by block, therefore can't continue descendingly, guarantee that operating personnel's hand is not subject to the injury of drift.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1, a kind of punch press with hand guard device, the workbench 2 that is used for place work piece that comprises drift 1 and below described drift 1, arrange, side at described workbench 2 is provided with block 3, and described block 3 slides and is arranged on the slide rail 4 that described workbench 2 one sides arrange.
In described block 3 one sides cylinder 5 is set, the piston rod that described block 3 is connected with cylinder connects, driving block 3 by cylinder 5 slides at slide rail 4, described cylinder 5 with is connected control device and connects, be provided with photoelectric sensor 6 for detection of operating personnel's hand at described workbench 2, described photoelectric sensor 6 be connected control device and connect, and described photoelectric sensor 6 is connected with the stop switch of drift.If that operating personnel's hand still below drift and between the workbench time, photoelectric sensor 6 sends a signal to the stop switch of control drift and the control device of control cylinder simultaneously when drift is descending.So that stop switch control drift stops is descending, and the control device control cylinder enters position between drift and the workbench so that cylinder promotes block, prevented that further drift from continuing descending problem under the effect of inertia.
Further, the thickness of described block 3 is between 10cm ~ 20cm, even lean drift so that drift can't continue descending if the thickness of block 3 produces block easily less than 10cm, the danger that operating personnel's hand still is pressed onto by drift, block thickness is greater than 20cm, appear at easily drift because inertia descending the time, block can not in time enter between drift and the workbench, so that drift directly overwhelms the problem of operating personnel's hand.
Claims (2)
1. punch press with hand guard device, comprise drift (1) and the workbench (2) that is used for place work piece that arranges in described drift (1) below, it is characterized in that: the side at described workbench (2) is provided with block (3), described block (3) drives by a cylinder (5), described cylinder (5) with is connected control device and connects, be provided with photoelectric sensor (6) for detection of operating personnel's hand at described workbench (2), described photoelectric sensor (6) be connected control device and connect.
2. a kind of punch press with hand guard device as claimed in claim 1, it is characterized in that: the thickness of described block (3) is between 10cm ~ 15cm.
