Abstract
The utility model discloses a safety protection device for a punch press, wherein a metal block is arranged between an upper die and a lower die, the metal block is connected with a telescopic device, and the telescopic device is arranged on the punch press; and the telescopic device comprises an air cylinder, a metal block, an electromagnetic valve, an air intake valve, an air inlet pipe and an air outlet pipe. As the metal block is arranged between the upper die and the lower die, wounding accidents caused by out of control of the punch press, a slider unexpected dropping of a sliding block or out of order of a photoelectricity protection device and the like can be prevented, so as to effectively prevent operators of the punch press from being hurt. With the adoption of an air cylinder telescopic device arranged at the rear part of the metal block, the metal block can be taken back when the punch press is in work, and the metal block stretches out when the punch press is not in work, thereby ensuring the normal operation of the punch press and the safety of the operators.
Description
Technical field
The utility model relates to punch press, relates in particular to a kind of punching machine safety device.
Background technology
At present, known punch press structure is to be made of patrix, upper bolster, counterdie, die shoe, sword wall, cutting edge gradient, air cushion, the briquetting of tossing about, guide pin bushing, guide plate, guide pillar, pilot pin, guide plate die.In national product, Sheet Metal Forming Technology is because more traditional machining has the economical with materials and the energy, the efficient height can make these advantages of product that machining is beyond one's reach to not high the reaching by various moulds application of operator's specification requirement, thereby its purposes more and more widely.But because punch press all is manually-operated, and not high to operator's specification requirement, staff is easy to stretch into the deathtrap; In case and under the situation that punch press is out of control, the unexpected whereabouts of slide block or photoelectric protector are malfunctioning, the action of continuous cutting will appear in punch press, this moment, operator's hand will be hurt by punch press.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of peace punching machine safety device, and the punch press work that makes is safer.
For solving the problems of the technologies described above, a kind of punching machine safety device of the utility model comprises metal derby and retractor device,
Described metal derby is arranged on punch press up and down between the punch die;
Described metal derby is connected with retractor device;
Described retractor device is connected with punch press.
Described metal derby is cylindrical iron block.
Retractor device comprises cylinder, magnetic valve, intake valve, air inlet pipe and an escape pipe;
Described metal derby is installed in the described cylinder;
One end of air inlet pipe is connected on the magnetic valve, and the other end is connected on the intake valve, and described intake valve is connected with cylinder;
Described escape pipe is connected with magnetic valve.
Therefore a kind of punching machine safety device of the utility model has following beneficial effect:
Be provided with metal derby up and down between the punch die, can prevent that punch press from because of punch press that reason causes hurts sb.'s feelings incident such as out of control, the unexpected whereabouts of slide block or photoelectric protector be malfunctioning, can avoid operating punch machine person injured effectively.
The cylinder retractor device at metal derby rear portion can make metal derby regain when punch press is worked, and stretches out when not working, and has both guaranteed the punch press operate as normal, has guaranteed staff's safety again.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
The structural representation of a kind of punching machine safety device that Fig. 1 provides for the utility model embodiment 1;
The structural representation of a kind of punching machine safety device cylinder that Fig. 2 provides for the utility model embodiment 1.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Embodiment 1:
A kind of punching machine safety device of the utility model; be provided with a cylinder 1 up and down between punch die; be provided with a cylindrical iron block 2 in the cylinder 1; cylinder 1 rear portion is connected with an intake valve 3; intake valve 3 is connected with an end of air inlet pipe 4; the other end is connected with magnetic valve 5, and magnetic valve 5 is connected with escape pipe 6.Behind punch press 7 power connections, after punch die installs, be in the situation of often opening, open intake valve 3, simultaneously power switch is opened, allow magnetic valve 5 be in working condition, allow cylinder 1 round iron piece 2 rest punch die lower bolster 8, and cylinder round iron piece 2 is transferred and punch die lower bolster 8 2-3MM of being separated by, when operator's both hands are pressed the punch press starting switch, this moment, punch press was started working
Patrix 9, the counterdie 8 of its punch die will close up, just can die-cut product, and safety guard---cylinder 1 will drive cylinder round iron piece 2 retractions simultaneously, and gas is run out of from cylinder by magnetic valve 5 and escape pipe 6, guarantees punch press 7 operate as normal.When punch press 7 is finished die-cut product; lower bolster will be opened automatically on its punch die; meanwhile; safety guard---cylinder 1 will be sent cylinder round iron piece 2 into punch die; gas enters cylinder by magnetic valve 5 and intake valve 3, and cylinder round iron piece 2 can adjust according to actual conditions with the distance of bolster.After the bolster of general punch die is opened; the operator just stretches out one's hand and gets product in the progressive die; if this moment, the punch press action was out of control; under the malfunctioning situation of photoelectric protector; the action of continuous cutting will appear in punch press, and operator's hand will be dangerous so, but safety guard has been arranged--and cylinder round iron piece 2 can be stuck between the upper and lower plates of punch die; just stay the space of next safety, definitely guarantee the safety of operator's hand.When punch press breaks down, earlier the punch press motor is switched to counter-rotating, and punch die is opened fully, again safety device round iron piece 2 is withdrawn in the mode of manual operation magnetic valve 5, and the security device source of the gas, treat that the machine maintenance personnel get rid of the continuous cutting fault, opening safety means continues operation again.
Therefore a kind of punching machine safety device of the utility model has following beneficial effect:
Be provided with metal derby up and down between the punch die, can prevent that punch press from because of punch press that reason causes hurts sb.'s feelings incident such as out of control, the unexpected whereabouts of slide block or photoelectric protector be malfunctioning, can avoid operating punch machine person injured effectively.
The cylinder retractor device at metal derby rear portion can make metal derby regain when punch press is worked, and stretches out when not working, and has both guaranteed the punch press operate as normal, has guaranteed staff's safety again.
The circular metal piece has guaranteed that cylinder is capable of expansion and contraction.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
