Abstract

A safety device for a punching machine comprises a lower die, an upper die, a template, die carriers, infrared transmitting or receiving devices, blanking chambers, an infrared light curtain, a working platform and a feeding passage, wherein the upper die is mounted on a punch pin of a punching device; the lower die is fixedly placed on the template through the die carriers; the lower die corresponds to the upper die up and down; the template is fixedly placed on the working platform; the two strip-shaped platy die carriers are oppositely placed on two sides of the upper die and the lower die in a clamping way, and the upper edges of the die carriers are higher than the working surface of the lower die; two ends of a passage formed between the two die carriers are respectively a feed opening and a discharge opening; the working areas of the upper die and the lower die lean to the discharge opening end, and the at least three pairs of infrared transmitting or receiving devices are correspondingly and respectively arranged on the die carriers on two sides which are close to the feed opening end, so as to form the infrared light curtain point to point; and the height of the infrared transmitting or receiving devices can be adjusted up and down, so as to ensure that the height of the feeding passage adapts to the situation that the punching sheet material can be placed flatly to enter the working area, and the infrared transmitting or receiving devices are connected to a driving power supply device and a flywheel brake device of the punching machine.

Description

A kind of safety device of punch press
Technical field
[0001] the utility model 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 due to operator's operate miss in production is very general, a lot of lathe manufacturer uses safety coefficient in order to increase product, actuation means to lathe improves, these improve is to control with the circuit of lathe by electro-optical system or infrared facility to be connected mostly, in order to can in time cut off the electricity supply when operate miss, the minimizing accident occurs.But often after 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 utility model 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 arranged 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 workbench (8), it is characterized in that: described mould bases (4) is two block length bar shaped tabular components, and relative clamping is placed in the both sides of patrix (2) and counterdie (1), and the upper limb of mould bases (4) exceeds the working face of counterdie (1), between two mould bases (4), formed passage two ends are respectively charging aperture and discharging opening, and make the working region (10) of upper and lower mould be partial to discharging opening one end, upper corresponding at least three pairs of infrared emittings or the receiving system (5) of arranging respectively of mould bases (4) near 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 utility model is simple in structure, easy for installation, safe and practical, even existing punch press is reequiped also saves very large cost, 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, return to normal production.
Description of drawings
Referring to accompanying drawing, Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model top view;
Fig. 3 is the utility model circuit diagram.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, specific features of the present utility model 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 arranged 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 workbench (8), the relative clamping of two mould bases (4) is placed in the both sides of patrix (2) and counterdie (1), and exceed the working face of counterdie (1), between two mould bases (4), formed passage two ends are respectively charging aperture and discharging opening, and make the working region (10) of upper and lower mould be partial to discharging opening one end, upper corresponding at least three pairs of infrared emittings or the receiving system (5) of arranging respectively of mould bases (4) near charging aperture one end both sides, regulating distance between the working face that infrared emitting or receiving system (5) make the infrared ray curtain (7) of formation and counterdie (1) is suitable for the punching press plate and enters and get final product.During operation, the punching press plate is 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 flywheel brake moment under the effect of relay separates, thereby returns to normal production.
