Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, an anti-mis-feeding device for a stamping progressive die comprises an automatic feeding machine 1 and a workbench 4, wherein the automatic feeding machine 1 abuts against one side of the workbench 4, a product material belt 2 is arranged on the automatic feeding machine 1, and a plurality of positioning holes 3 are vertically formed in the product material belt 2; a stamping die 5 is fixedly arranged on the workbench 4, the stamping die 5 is composed of a movable die and a fixed die, the movable die is positioned right above the fixed die, a product material belt 2 horizontally passes through the movable die and the fixed die without contacting, one side of the interior of the movable die, which is far away from the automatic feeder 1, is provided with a reset spring assembly 6, an ejector rod 7, a mis-feeding detection needle 8, a correction positioning needle 9, a connecting rod 10 and a point switch 11, the correction positioning needle 9 and the mis-feeding detection needle 8 are arranged side by side from left to right, the upper ends of the correction positioning needle and the mis-feeding detection needle 8 are inserted into the movable die, the lower ends of the correction positioning needle and the mis-feeding detection needle are vertically extended to the direction of the positioning hole 3 from the interior of the movable die, the mis-feeding detection needle 8 and the ejector rod 7 are movably arranged in the interior of the movable die, the mis-feeding detection needle 8, the ejector rod 7 and the, the other end of the pressing rod abuts against the inching switch 11, the inching switch 11 is electrically connected with a PLC 12, and the PLC 12 is also electrically connected with an opening and closing system of the stamping die 5.

Through the technical scheme, assuming that the feeding step pitch of the automatic feeding machine 1 is Xmm, when the feeding error is small (namely the actual feeding step pitch of the automatic feeding machine 1 is between X-0.3mm and X +0.3mm), the moving die of the stamping die 5 drives the mis-feeding detection needle 8 and the calibration positioning needle 9 to extrude into the positioning hole 3 of the product material belt 2, and the product material belt 2 is calibrated and positioned through the splicing matching between the mis-feeding detection needle 8 and the calibration positioning needle 9 and the positioning hole 3, so that the feeding step pitch of the product material belt 2 is closer to Xmm, and the feeding precision of the automatic feeding machine 1 is improved;

when the feeding error is large (that is, the actual feeding step distance of the automatic feeder 1 is smaller than X-0.3mm or larger than X +0.3mm), because the deviation between the axes of the misfeed detection needle 8 and the correction positioning needle 9 and the axes of the positioning holes 3 is too large, the stamping die 5 cannot drive the misfeed detection needle 8 and the correction positioning needle 9 to be inserted into the positioning holes 3, the ejector rod 7 is jacked upwards when the stroke of the misfeed detection needle 8 is blocked along with the downward pressing of the movable die, the ejector rod 7 compresses the return spring assembly 6, so that the return spring assembly 6 contracts, and during this period, along with the movement of the misfeed detection needle 8, the connecting rod 10 originally in the clamping groove 13 slides out of the clamping groove 13, the connecting rod 10 triggers the click switch 11 under the extrusion action of the side wall of the misfeed detection needle 8, the PLC controller 12 is used for closing the stamping die 5 after the click switch 11 is opened, so that the material belt is scraped or even collides with the product 2 before the correction positioning needle 9 and the misfeed detection needle 8 And the stamping die 5 is stopped in time, so that the product, the stamping die 5 and the correction positioning pin 9 are prevented from being damaged.

Further, as shown in fig. 1 and 3, the positioning holes 3 are uniformly arranged at equal intervals, and the distance between two adjacent positioning holes 3 is equal to the feeding step distance of the automatic feeding machine 1 and also equal to the distance between the mis-feeding detection needle 8 and the calibration positioning needle 9, so that the mis-feeding detection needle 8 and the calibration positioning needle 9 can be matched with the positioning holes 3 to position and calibrate the product material belt 2 in each feeding stroke.

Further, the outer diameter of the error feeding detection needle 8 is 0.3mm smaller than the outer diameter of the correction positioning needle 9, so that the error feeding error of the automatic feeding machine 1 is within the range of +/-0.3 mm, the error feeding detection needle 8 cannot be triggered to jack up, the stamping die 5 at the moment normally works, and the correction positioning needle 9 and the error feeding detection needle 8 can be smoothly inserted into the positioning hole 3 to correct the product material belt 2.

Further, mistake censorship needle 8 is than correcting the outside of pilot pin 9 to the movable mould and stretching out 10mm more, ensures that mistake censorship needle 8 can be preferentially inserted to locating hole 3 department, has played the effect to feeding error preliminary examination, early warning, and is stronger to the security and the protectiveness of equipment, "10 mm" that mention in the above-mentioned content is only as an example, and technical personnel in the field can change according to actual demand, still is in the utility model discloses an within the protection scope.

Further, as shown in fig. 3, the inner diameter of the positioning hole 3 is equal to the outer diameter of the calibration positioning pin 9, so that the calibration positioning pin 9 can be inserted into the positioning hole 3 exactly, and the calibration is more accurate.

Further, as shown in fig. 2, the inner wall of the clamping groove 13 is arc-shaped, and the end of the connecting rod 10, which is matched with the clamping groove 13, is also arc-shaped, so that the matching between the connecting rod 10 and the clamping groove 13 is smoother and smoother.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
