Abstract

The utility model relates to a risk-preventing device for an operating punch machine, comprising a rotating disk provided with a V-shaped notch and arranged at the shaft end of a main shaft, a base provided with a longitudinal slideway and arranged on a machine body, a horizontal sliding plate provided with a frame-shaped rod at front end and matched with the longitudinal slideway, a cross shaft provided with a crank shaft at shaft end and an impeller pushing the horizontal sliding plate to move forward at the upper part of the horizontal sliding plate, a retracting spring having one end tied to the base and the other end tied to the horizontal sliding plate and a rod system arranged between the rotating disk and a crank for changing the rotation of the rotating disk into the swing of the crank. The risk-preventing device for an operating punch machine having a completely mechanical structure can push a hand holding punching materials out of a lower die when the horizontal sliding plate moves forward in order to avoid accidents.

Description

The operating punch machine risk-preventing device

The utility model relates to a kind of operating punch machine risk-preventing device.

The industrial accident of operating punch machine is many, and this mainly is to hold towards the hand of material to lose in action due to the coordination with the pin of stepping on switch, particularly when work is relatively more tired, and the more difficult coordination of trick action, accident is also just more.

The purpose of this utility model provides a kind of mechanical operating punch machine risk-preventing device.

This operating punch machine risk-preventing device has the rotating disk that is installed in the punch press main-axis end and is provided with V-notch, be installed on the fuselage and be provided with the base of end slipway, join and front end is provided with the horizontal slide plate of shaped as frame rod member with the end slipway cunning, being arranged on the top of horizontal slide plate and axle head is equipped with and the impeller that promotes the horizontal slide plate reach is housed in the middle of the crank axle and is bearing in transverse axis on the fuselage, one end lies in the base other end and lies in the retracting spring of horizontal slide plate and be arranged on rotating disk and be converted to the leverage of the swing of crank with the rotation with rotating disk between the crank, and this leverage is provided with drive rod with the roller of the side face contact of rotating disk by being installed in punch press countershaft axle head and rod end, fuse and be connected with the tappet hinge with an end with drive rod with the tappet that drive rod forms angle, the other end is formed with the hinged connecting rod of crank.

Illustrate particular content of the present utility model below in conjunction with drawings and Examples.

Fig. 1: schematic diagram of mechanism of the present utility model;

Fig. 2: the structure chart of horizontal slide plate part;

Fig. 3: A-A cutaway view.

As shown in the figure, operating punch machine risk-preventing device described in the utility model has the rotating disk 3 that is installed in punch press main shaft 1 axle head and is provided with V-notch 2, be installed on the body 4 and be provided with the base 6 of end slipway 5, join and front end is provided with the horizontal slide plate 8 of shaped as frame rod member 7 with end slipway 5 is sliding, being arranged on the top of horizontal slide plate 8 and axle head is equipped with 9 centres of crank and the impeller 10 that promotes horizontal slide plate 8 reaches is housed and is bearing in transverse axis 11 on the body 4, one end lies in base 6 other ends and lies in the retracting spring 12 of horizontal slide plate 8 and be arranged on rotating disk 3 and be converted to the leverage of the swing of crank 8 with the rotation with rotating disk 3 between the crank 9, and this leverage is by being installed in the drive rod 15 that punch press countershaft 13 axle heads and rod end are provided with the roller 14 that the side face with rotating disk 3 keeps in touch, fuse and be connected with tappet 16 hinges with an end with drive rod 15 with the tappet 16 that drive rod 15 forms angles, the other end is formed with crank 9 hinged connecting rods 17.Described shaped as frame connects left bar that part 7 connects by rear end same level slide plate 8 with right bar and be arranged on left bar and form with right bar front end and with the preceding bar that left bar is connected with right bar; The position of horizontal slide plate 8 on fuselage 4 should make with the counterdie of the preceding bar in the shaped as frame rod member 7 of horizontal slide plate 8 reaches from punch press to be passed through, and after horizontal slide plate 8 reach strokes are finished, can make the drift that moves both vertically from by falling horizontal slide plate 8, the frame hole 18 that preceding bar, left bar and right bar surrounded again, change the position of base 6 on fuselage 4, just can determine the initial position of horizontal slide plate 8 on fuselage 4; The design of leverage will guarantee that horizontal slide plate 8 has enough reach strokes, and the length of tappet 16 and connecting rod 17 should be adjustable, and the length that several pans just can change tappet 16 and connecting rod 17 is set on tappet 16 and connecting rod 17.The simplest impeller 10 is push arms that same level slide plate 8 keeps in touch, and also can be mounted in the gear on the transverse axis 11, at this moment, the tooth bar with gears engaged should be set on the horizontal slide plate 8.

Above-mentioned operating punch machine risk-preventing device is frame for movement fully, when horizontal slide plate reach, and before drift falls as yet, places the shaped as frame rod member of horizontal slide plate front end promptly will hold towards the operator of material and releases outside the counterdie, has so just reached the purpose of avoiding the accident generation.
