SU1368086A1 - Arrangement for feeding and removing blanks from the press working zone - Google Patents

Description

The invention relates to the mechanization of metal forming processes and can be used to feed blanks into the working area of a press.

The purpose of the invention is the expansion of technological capabilities by combining the operations of delivery and removal of blanks.

Figure 1 shows the proposed device, a General view; figure 2 is the same, top view; on fig.Z - section aa in figure 2; figure 4 - section bb in figure 1; figure 5 - section bb In figure 1.

The device for supplying and removing workpieces from the working area of the press of finished parts consists of a housing 2 installed on the base 1, equipped with a side receiving window 3 and a tray 4 equipped with an external alarm sensor 5 connected to the magazine bin 6, while continuing the channel of the feeder tray parallel, replaceable side rails 7 are attached.

The guides 8, a slider 9, fitted with a removable gate 10 connected to the actuator 11, are attached to the housing from below.

Parallel to the guide above the side interchangeable guides 7 of the feed tray, Z-guides 12 are movably mounted, the non-working ends of which are provided with longitudinal apertures 13, hinged fingers 14 with the slide body, and the working hinge windows of the rack, made in the form of a continuation of the feed channel channel, and provided with measuring copying rulers 15 attached from the inside, in contact with the guide windows of the stand, the lower Z-shaped grippers 16 of the guides are located at the front of the stand and are interconnected in the spring 17 tension.

Parallel guides 1B with figured holes 19, the non-working ends of which are hingedly connected to the slide, and the workers are mounted through lengthwise lines, are additionally installed parallel to the Z-shaped guide.

the holes on the pin 20 located in the pillars of the rack are equipped with axles 21 hinged to them, sliding cam stops made in the form of eccentrics 22 mounted inside the gripper cases, which are equipped with interchangeable prisms 23 for clamping and moving the blanks 24.

The device works as follows.

The blanks 24 are received from magazi-i at 6 and along the tray 4 are sent to the receiving window 3, pass through the sensor 5

external signaling, interacting with the press drive, and then entering the feed stand channel formed by the interchangeable guides 7 and the guide 8 on which they lie. After that automatically

the actuator 11 is turned on (or by the stroke of the press drive shaft), the slider 9 with the bolt 10 is moved together with the parallel Z-shaped guides 12

with grippers 16 in the feed direction. In this case, the workpiece 24 is moved simultaneously with the gate 10 to the prisms 23 by the grip 16, which force the spring 17 to clamp the bite 24 and carry

it to the working position of the stamp, and from that moment on the joint movement of the additional parallel guides 18 in the windows of the housing 2 of the rack, due to

the articulation of the longitudinal bore 13 with a finger, the cams-lugs 22 swiveling in the housings of the grippers 16 and overlapping the magazine tray formed

parallel guides 12, and thus dumping or moving the previous billet to another position.

If it is necessary to change the device to other sizes of workpieces, fingers are moved or replaced, copying measuring lines 15, interchangeable guides, eccentrics 22, prisms 23, adjusting the gate 10 and

sensor 5 external alarm.

The level of the device relative to the working plane is regulated on the base 1 by a wedge 25 or linings.
