Abstract
The utility model relates to a safety device of punching machine for ordinary foot-switch typed punching machine, particularly a protecting means of personal safety for the operator whose one hand goes into the hazardous area of operating punching machine. The purpose is to design a safety device with the advantages of simple structure, low cost, easy control, convenient installation and convenient maintenance. The safety device of punching machine is shown in figure, the control mechanism which is composed of moving and combining dry reed switches is arranged on the worktable of punching machine where is convenient to operate by operator by the tunable magnetic support (8). The actuating device which is composed of linguiform sliding pin (13), locking pin (11) with magnet, etc. is arranged on the midway in where the connecting rod of the foot-switch moves backwards and forwards. The control mechanism, the actuating device and the controlled system (10) make the foot-switch in locking state often.
Description
The utility model relates to the punch press of common floor push type, the especially singlehanded personal safety protector that enters the punch press of hazardous area operation.
At use dynamic models such as blanking, punching, moulding in the punching production that fixed die moves, the packing into and take out of workpiece, the hand direct controls of most personnel selections still now.For preventing the generation of personal injury, labour department has made regulation, and this generic operation must adopt safety precautions.
Known technology, for example No. 9799/1983 disclosed a kind of safety device that moves with the gauge tap control jumper bar of linkage and associating of Japanese patent application.When operative employee one started the pedal of punch press, if be operative employee's hand or other barriers rather than workpiece between dynamic model and fixed die, the detector on the safety device will be found before jumper bar begins punching press, and stop clutch to drive jumper bar.Even remove between mould at release the pedal remote holder or other barriers, the blocking-up behavior will continue, and keeps jumper bar not fall, and jumper bar just can restart to impact after being returned to the normal position fully.Therefore, the jumper bar misoperation can not take place.Yet this safety device adopts the gauge tap control jumper bar motion of detector and associating, and structure is complicated, and difficulty is installed, and does not make us satisfied fully.
The purpose of this utility model provides a kind of simple in structure, and the punching machine safety device that sensitivity and reliability are high is installed easily.
The utility model is made up of operating mechanism, control system and executing agency's three parts.Small-sized movable closing dry reed switch is housed on the operating mechanism, can sensitivity opens and closes circuit fast, the pedestal of this mechanism is an adjustable magnet, operating mechanism can be placed on the workbench operator's convenience smoothly.Executing agency is made up of the parts of ligulate sliding pin on the floor push connecting rod and carry magnet lock pin, is contained in the way that the floor push connecting rod moves up and down with joining.Control system is according to the action of the direct controlling magnet lock pin of the signal of movable closing dry reed switch.For the coordination that makes the operator and safe and reliable, taked relative measures in the control system.Used the punch press of this covering device, floor push is in frequent locking states.Its safeguard protection principle is as follows: when the operator takes out workpiece with hand; put into to be processed; in the process that withdraws between mould; take advantage of a situation and touch the operating mechanism that rubs; control system is just commanded the action of magnet lock pin rapidly, and the ligulate sliding pin on the floor push connecting rod is discharged, and steps on pedal in the regular hour; jumper bar moves, and finishes the punching press stroke one time.If do not abide by the said procedure operation, the ligulate sliding pin on the floor push connecting rod is not released, and not only jumper bar can not move, and can send alarm signal.Simultaneously, surpass certain hour behind the operating mechanism that rubs, still do not step on pedal if hand touches, magnet lock pin self-return then, floor push returns to locking states again, and is safe and reliable to guarantee.
Fig. 1: the installation site schematic diagram of this device on punch press.
Fig. 2: operating mechanism structure diagram.
Fig. 3: executing agency's structure diagram.
Now detail is described a preferred example of the present utility model with reference to the accompanying drawings.
As shown in FIG., punch press (1) is a common punch press that has punching press cover half (2), dynamic model (3) and pedal (14) and this device.Magnet steel with cover (5) links with housing (7) by the coupling pin (6) of band back-moving spring (15), and can rotate around (6), tongue tube (16) is fixed on the housing (7) of packing into together on the phenolic laminated sheet (17), above-mentioned member is formed a movable closing dry reed switch, be contained on the adjustable magnetic support (8), constitute the operating mechanism of this device together.This mechanism is by adjustable magnetic support (8), can place on the punch press workbench operator's convenience smoothly, and lead (9) directly links to each other with control system (10), touches the magnet steel with cover (5) that rubs and just can sensitivity open and close circuit apace.Ligulate sliding pin (13) in the executing agency is contained on the floor push connecting rod, the lock pin of carry magnet (11) is fixed on the punch press (1) by screw (18) by stand (12), the two installation site is adopted and is joined work, lead (19) directly links to each other with control system (10), and floor push can be in frequent locking states.Both made mistake step on pedal (14), floor push also can not move, and the audible-visual annunciator (20) in the device can give the alarm immediately.Simultaneously, for making operator's coordination, in control system (10), adopting has delay circuit, and for misoperation does not take place the lock pin (11) that makes carry magnet, control system (10) is middle with interference protection measure is arranged.
This device is compared with known technology, and is simple in structure, and cost is low, the reliability height, and operation is easily grasped, and installation, maintenance is convenient, does not substantially affect production efficiency.
Claims (1)
- A kind ofly be used for common floor push type punch press; especially the singlehanded personal safety protector that enters the punch press of hazardous area operation; it is characterized in that magnet steel with cover (5) links to each other with the housing (7) of interior dress tongue tube by coupling pin (6); and be contained on the adjustable magnetic support (8); form operating mechanism, place on the workbench operator's convenience smoothly.Ligulate sliding pin (13) on the floor push connecting rod and the lock pin (11) etc. that is fixed on the carry magnet on the punch press (1) are formed executing agency, are installed in the way that the floor push connecting rod moves up and down.Operating mechanism, executing agency and control system (10) make floor push be in frequent locking states.
