Description

one

The invention relates to the processing of metals by pressure and can be used in various machine building industries to control sheet blanks fed into the work area.

It is known for controlling and sorting the thickness of sheet blanks, equipped with a ball-tip probe connected through a lever system with an indicator connected by an angular lever with a slider of the executive body of the device. The downside of the known device is that it is difficult to control the number of blanks supplied. what is required is a constant base, against which the thickness of the sheet blanks is measured.

The closest set of features and the achieved effect to the proposed device is

to control the number of sheet blanks supplied to the working area, comprising a housing, a system of levers connected by a spring, and a limit switch electrically connected to the drive of the processing machine, in particular cal2.

The disadvantage of this device is that there is no possibility to control blanks that are incorrectly oriented relative to the level of transportation and of different thickness.

, 5 The purpose of the invention is the expansion of the technological capabilities of the device by providing the ability to control improperly oriented and different thickness blanks.

20 This goal is achieved by having a device for controlling the number of sheet blanks fed into the working area comprising a housing, a system of levers interconnected by a spring, and. a limit switch electrically connected to the drive of the processing machine, in particular a press, is provided with a plate mounted on the axis of the housing with the possibility of oscillating movement in a vertical plane and mounted on it a pressure plate on which one of the levers is placed, with a flat spring mounted on the pressure plate and an intermediate plate connected to the pressure plate through a flat spring, and the other lever is fixedly mounted on the plate. FIG. 1 shows the device, a general view; in fig. 2 - section A-L in FIG. 1; in fig. 3 view B in FIG. 2. The device contains a body 1 with a plate 3 mounted on axis 2 with lever A. A plate 3 fixed on it. In plate 3 on axis 5, pressure is fixed on plate 6 with lever 7, a flat spring 8, the free end of which abuts against the intermediate plate. 9 with a limit switch 10. The levers C and 7 are interconnected by a spring 11. Through the housing 1 and the plate 3, an adjustment screw 12 passes, resting against the intermediate plate 9 and serving to adjust the lever 7, the screw 13 passes through the housing 1 and rests into plate 3 and the lever and 4. The device operates as follows. The housing 1 is installed at the height of transporting the sheet blanks and then using an adjusting screw 13 rotates the plate 3 around the axis 2, thereby setting the lever k to the required transport height. The adjusting screw 12 sets the gap between the levers and 7 on the appropriate thickness of the sheet. When ripfci passes through the device of two sheet blanks, the lever 7 is deflected to the lower position and turns off the limit switch 10, which stops the drive of the machine. When the lever 7 is deflected to the lower position, the intermediate plate 9 does not lower, since the flat spring 8 constantly holds the end of the free end 8 in one and the same position. With the passage of the sheet blank, the lever tracks its surface, thereby ensuring, through the spring 11, setting the lever 7 to the actual transport height. When the sheet blank deviates from the required transport height, it rests against the lever, which slides over the surface of the blank, rises, and with the help of the spring 11 raises the lever 7 to the same height. The proposed device protects the working area from simultaneously feeding two sheet blanks and allows control improperly oriented and multi-layer blanks. Apparatus of the Invention A device for controlling the number of sheet blanks supplied to a work area comprising a housing, a system, levers connected by a spring, and a limit switch electrically connected to the drive of the processing machine, in particular a press, This is so that, in order to expand the technological capabilities of the device by allowing the control of improperly oriented and differently thick blanks, it is equipped with a plate installed in the housing on an axis with the possibility of oscillating The movement in a vertical plane and mounted on it is a pressure plate on which one of the levers is placed, a flat spring fixed on the pressure plate and an intermediate plate connected to the pressure plate through a flat spring, and the other lever fixedly mounted on the plate.
