Abstract
The invention provides a safety device of a punching machine. The safety device comprises a lower die, an upper die, a template, die carriers, infrared transmitting or receiving devices, a blanking chamber, an infrared light curtain, a workbench and a feed channel; the upper die is arranged on a punch of a stamping device; the lower die is fixedly arranged on the template through the die carriers; the upper die corresponds to the lower die vertically; the template is fixedly arranged on the workbench; two long strip shaped plate die carriers are oppositely clamped at two sides of the upper die and the lower die; and the upper edges of the die carriers are higher than the work surface of the lower die; two ends of a channel formed between the two die carriers are respectively a feed port and a discharge port; the work areas of the upper and lower dies are biased towards one end of the discharge port; the die carriers close to two sides of one end of the feed port are respectively provided with at least three pairs of infrared transmitting or receiving devices, so as to form the infrared light curtain point by point; the height of each infrared transmitting or receiving device can be adjusted vertically, so that the height of the feed channel can be enabled to be suitable for flatly putting stamping sheet material into the work areas; and the infrared transmitting or receiving devices are connected with a punching machine driving power supply device and a flywheel brake device.
Description
Technical field
The present invention relates to a kind of safety device of punch press.
Background technology
Punch press is a kind of at the comparatively general tool of production of processing industry use, because most of punch press is equipped with the major diameter flywheel, so that larger inertia and the impulsive force of generation enhanced productivity, also can generate huge stamping press even therefore driving force is very little.Also bring very large potential safety hazard to the operator thus, the phenomenon that damages owing to operator's operate miss in the production is very general, a lot of lathe manufacturers use safety coefficient in order to increase product, actuation means to lathe improves, these improve is to be connected with the circuit control of lathe by electro-optical system or infrared facility mostly, in order to can in time cut off the electricity supply when operate miss, the minimizing accident occurs.But often behind dump, huge flywheel still keeps the inertia that necessarily turns round, and causes drift not brake moment, so still there is certain potential safety hazard.
Summary of the invention
The present invention is exactly the safety device that discloses a kind of punch press for addressing the above problem, and comprising: counterdie (1), patrix (2), template (3), mould bases (4), infrared emitting or receiving system (5), material feeding chamber (6), infrared ray curtain (7), workbench (8), feeding-passage (9); Patrix (2) is installed on the drift of decompressor, and counterdie (1) is installed with on template (3) through mould bases (4), and makes counterdie (1) corresponding up and down with patrix (2), and template (3) is fixedly arranged on the workbench (8); It is characterized in that: described mould bases (4) is two block length bar shaped tabular components, and relative clamping places the both sides of patrix (2) and counterdie (1), and the upper limb of mould bases (4) exceeds the working face of counterdie (1), formed passage two ends are respectively charging aperture and discharging opening between two mould bases (4), and make the working region (10) of upper and lower mould be partial to discharging opening one end, near upper respectively corresponding at least three pairs of infrared emittings or the receiving system (5) of arranging of the mould bases (4) of charging aperture one end both sides, so that point-to-point formation infrared ray curtain (7), infrared emitting or receiving system (5) but the height up-down adjustment, guarantee that distance between the working face of the lower limb of infrared ray curtain (7) and counterdie (1) is that the height of feeding-passage (9) is suitable for the punching press plate and keeps flat and enter the working region and get final product; Infrared emitting or receiving system (5) be through low-tension supply power supply, and infrared emitting or receiving system (5) are connected to through relay that punch press drives electric supply installation and the flywheel brake gear gets final product.
This invention is simple in structure, easy for installation, safe and practical, even existing punch press is reequiped the also very large cost of saving, and because the operator is in charging aperture one end always, and keep certain distance with mold work zone, increased safety coefficient, in case it is that the positions such as health or hand enter the working region that mistake appears in operation, surely can block or block the infrared ray curtain, electric power system is namely cut off the electricity supply rapidly, stop power supply, and the flywheel brake system also can be braked moment, avoid the injury to operating personnel, in case it is normal that the infrared ray curtain recovers, several lighting restarted electric power system at once, returns to normal production.
Description of drawings
Referring to accompanying drawing, Fig. 1 is structural representation of the present invention;
Fig. 2 is top view of the present invention;
Fig. 3 is circuit diagram of the present invention.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, specific features of the present invention is described further.
Referring to Fig. 1～Fig. 3, a kind of safety device of punch press comprises: counterdie (1), patrix (2), template (3), mould bases (4), infrared emitting or receiving system (5), material feeding chamber (6), infrared ray curtain (7), workbench (8), feeding-passage (9) and working region (10); Patrix (2) is installed on the drift of decompressor, counterdie (1) is installed with on template (3) through mould bases (4), and make counterdie (1) corresponding up and down with patrix (2), template (3) is fixedly arranged on the workbench (8), the relative clamping of two mould bases (4) places the both sides of patrix (2) and counterdie (1), and exceed the working face of counterdie (1), formed passage two ends are respectively charging aperture and discharging opening between two mould bases (4), and make the working region (10) of upper and lower mould be partial to discharging opening one end, near upper respectively corresponding at least three pairs of infrared emittings or the receiving system (5) of arranging of the mould bases (4) of charging aperture one end both sides, regulate distance between the working face that infrared emitting or receiving system (5) make the infrared ray curtain (7) of formation and counterdie (1) and be suitable for the punching press plate and enter and get final product.During operation the punching press plate kept flat from charging aperture (9) and be advanced to the working region, finished product or pin material are namely sent from material feeding chamber (6) or discharging opening, in case operator's hand or other position push the working region because of carelessness or near the working region, infrared ray curtain (7) must be blocked or block in hand or other position, safety device cuts off the driving power of punch press at once, and fall the flywheel brake, and stop drift to fall, avoid accident to occur.When the infrared ray curtain recovers normal, the punch press driving power restores electricity at once, and the flywheel brake separated in effect lower moment of relay, thereby returned to normal production.
