Description

I

The invention relates to the cold working of metals by pressure and can be used to feed sheet material into the working area of a press.

A device is known for supplying a strip material to a working area of a press, containing a base with horizontal guides, along which the feed carriage (table) moves, carrying a rack, which engages with a gear mounted on a drive shaft. The drive shaft is mounted at the base, and at one of its ends of the ratchet assembly is driven from the movable part of the press in this case from the drive shaft of the press via a crank mechanism lj.

It is also known to have a device for feeding pollen material into a working zone of a press, comprising a base with horizontal guides along which the feed carriage moves.

driven by the movable part of the press. The feed carriage is made in the form of a plate, in which a groove is made dp the passage of the working HIT tool 2 J.

In known devices does not provide the possibility of lifting the material (strip) above the working area of the press.

The aim of the invention is to improve the performance of the stamping process by allowing the strip to be raised above the working area of the press.

The goal is achieved by those.

Claims (2)

15 that the device for feeding the strip material into the working area of the press, containing a feeding carriage driven from the movable part of the press through the converting mech machine for Z20 fixed on the base of the winding carrier 1 "and executed in the form of a plate with a groove for the passage of the working tool, is equipped locked on the carriage and positioned in the groove C1o «(it is geometric with respect to the feed axis plate springs with grooves to accommodate the material, and pop-up yen in the form of sliders interacting with the torp of the material on the carriage with the possibility of adjusting the movement parallel to the material feed direction. The transforming mechanism is made in the form of gear racks, gears, which engage with them and connected to the mobile part of the press through the bog coupling, fixed in the carriage. device, general view; on Lig.2 - section AA on. FIG. Ia fig.Z-section BB in Fig.2 in Fig.4 - view B in Fig .; on 4Н1Г.5 - section Г-Г on ФНЕГ.2. The device for feeding the strip material into the working area of the press comprises a frame 1 with horizontal guides 2, along which the feed carriage 3 moves. On the flow carriage 3, there are fixed (or made in one piece) gear racks 4 and a shock absorber made in the form of T-different plate springs, one end of each of which is fixed to (the carriage 3, and the other has a groove 6 for the passage of the sheet 7. The carriage 3 is made in the form of a U-shaped plate, and the plate springs 5 are located along the side iCTOpoH of the feed carriage 3 . the carriage 3 is fixed to it by stops 8 with the possibility of adjusting movement in a direction parallel to the direction of movement of the feeding carriage 3. The stops 8 are fixed on the bottom of the carriage 3 by screws 9 located in the grooves filled in the stops 8. On the directions 2 the brackets are fixed 10 and 11, in which, with the aid of sub-machines 12, a shaft 13f is attached, which holds the jaws 14 and enters 8 into engagement with the gears of the rack 4. At the ends of the shaft 13 there is an idle overtaking clutch 5, on the body 16 (holder) of which the lever 17 (crank) is fixed and sharii on it but has one end fixed {rod 18 (rod), the other end of which is pivotally mounted on the slider 19, 20. A press ying podaizh her carriage 3 oolyve length 1 | sheet 7 on l / j, which 84 provides for the cutting of parts from sheet 7, the engagement of gears 14 with toothed rails 4. Between the supporting surface O of the feed carriage 3 and the supporting surface b of the stops 8 the sheet 7 is clamped. The housing 18 of the friction overrunning clutch 15 by means of the rollers 21 are connected with an asterisk 22 fixed on the shaft 13. The device for feeding the strip material into the working area of the press works as follows. Sheet 7 is passed through the grooves 6 of the leaf springs 5 and the abutment 8 is pressed against the supply carriage 3. The stops 3 4 are being screwed 9. With the slide J9 moving up, the slide 19 through the pull J8 and the lever 17 actuates the housing 16 of the friction free-wheeling coupling 15, which, through the rollers 21 and the sprocket 22, rotates the shaft 13. The shaft 13 through the gears 14 and the gear racks 4 moves the feed carriage 3 with the sheet 7 along the guide 2 to the right (to the working zone of the press 20) by the feeding step. During the course of the slide 19 down, it goes through t 18 and the lever 17 turns the body 16 in the opposite direction. In this case, the rollers 21 do not transmit the motion of the sprockets 22. The shaft 13, and hence the feed carriage 3, are fixed. When W: 1, the parts (or blanks) of sheet 7 are moved downward, bending the leaf spring 5. With the slide 19 moving up, the leaf spring 5 ARE Straightened and lift sheet 7 up. Then the cycle repeats. Claim 1. Device for supplying strip material to the working area of the press, comprising a carriage driven by a movable part of the press through {feudoobrazuyu mechanism for fixing on the base of the guides, carrier and made in Step 1 pins with a groove for the passage of the working tool. distinguished by the fact that in order to increase the punching process by increasing the ability to raise the polo over the working area of the press, oijto CHateeHp mounted on the carriage and spaced in the groove symmetrically from the axis of the feed plate plates of the | clamps are made in the form of sliders, interacting with the end of the material and fixed on the carriage with the possibility of an adjustment movement parallel to the direction of the material feed. 2. The device according to claim 1, characterized in that the transforming mechanism is made in the form of toothed racks, sheherens, which enter into engagement with them and connected with the movable part of the press through the overrunning clutch.
