Description

The present invention relates to devices for automatically folding hooks, which can be used for this purpose in a number of cases, especially in the manufacture of electric incandescent lamps, which, on the one hand, increases productivity, reduces the cost of production, and on the other hand, improves product quality.

The essence of the proposed device can be understood from consideration of the attached drawing, in which FIG. 1, 2 and 3 depict a general view of the device in three projections and FIG. 4 and 5 are electrodes before bending and after bending.

Block 1 has a bottom 2, which in one way or another is attached to the workplace. A cover 9 is placed on the block 1. At the front of the block there is a support stand 23, which to some extent plays the role of a guide when the lamp base is inserted into the device, in which the hooks must be bent. Under the lid 9 there is a platform on which the RO operating time moves the parts described below.

In the front part, under the cover 9, there are three holes 16 and 17 for inserting the leg. Middle screwdriver (68)

Section 16 is inserted into glass bead, and in the extreme 17-wire electrodes, at the ends of which this device must hooks are bent. On the opposite side of the pad there is a device for bending hooks consisting of several parts 5, 6, 7, 8, 10, 11, 12, 13. On the bottom 2 a slider 3 is fixed, which can move in one horizontal direction, and the stroke it is limited by two stop screws 4 and 22, which can be screwed to the desired depth in block 1. Screw 4, having a thread at the end, passes through the slider 3.

A mandrel consisting of parts 14, 14, 19, 20 rests on the lower part of the slider 3, which can move vertically when its projection 20 hits the step of the slider -3. The protrusion 20 is pressed to the bottom of the slide 3 by means of a cylindrical coil spring 18. The plate 19 serves to guide the movement of the parts 18, 20. At the top of the described part there is a mandrel 14 with stops 14 used to form the hook.

On the slider 3 are attached two levers 5, which can rotate (as around

axes) around the screws 7 screwed into the slider 3. These levers are terminated by cams for crimping hooks on the electrodes shown in FIG. 2 dotted line. On the other hand, levers 5 st chuta spring 6.

To limit the movement of the levers, screws 8, tightening the wedge 10, screwed into the screws, are screwed into them.

Two levers 11c are fastened to the block 1 with screws 12 with cams so that these levers can rotate around screws 12, as about an axis. Cams of levers 11 tighten the stop screws to limit and adjust the travel of these levers. Both levers are covered and folded by a retaining spring 13 until they come into contact with the wedge 10. The ends of the levers are shown in the drawing by a dotted line, the end parts having two projections and on the side near one of them is a trough.

One protrusion presses the end of the bent electrode to the mandrel 14, protruding up above the platform at a certain position of the slide 3, and the other bends the electrode, and the stop pin 15 enters the depression.

The operation of the device is as follows. Shtabik and the electrodes of Kok shown in FIG. 4. In this case, the slider 3 is in the extreme right position, resting against the stop screw. At this time, the ends of the feet electrodes reach the pins 15, while the mandrel 14 is lowered down by the spring 18, flush with the platform on which the lid 9 is located.

Further, the slider 3 with all the parts attached to it moves to the left.

When the protrusion 20 jumps onto the step of the slider 3, the mandrel 14 protrudes over the platform and to it one of the end protrusions of the levers 11 presses the hinge of the bending electrode, and the other bends at an angle of 90 °.

Upon further advancement of the slider 3 to the left, the cams located at the ends of the levers 5 complete the bending of the electrodes to the required shape. The extension of the levers 11 is produced by a wedge 10.

After this operation, the slider 3 moves back (to the right). In this case, the cams of the levers 5 descend from the bent hooks, the mandrel 14 is lowered to the level of the platform, and the leg is pulled out of the device. The ready leg with the curved ends of the electrodes takes the form shown in FIG. five.

The device may be set in motion in one way or another, for example, with a foot pedal.

The subject matter of the invention.

A device for bending hooks on a wire, for example, on electrodes of electric lamps, characterized by the use of a pad 1 provided with a mandrel 14 movable up and down with stops 14 cooperating with spring-loaded levers 11 and 5, the first of which are attached to the block 1 and are under the influence of the wedge 10 located on the slider 3, and the second attached to the slider 3.
