DETAILED DESCRIPTION
[0024] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further detailed in combination with the drawings and examples.
[0025] In one embodiment, as shown in Figures 1-4 A stamping progressive die misfeed detection device, including workbench 1, support base 2, length detection mechanism and offset detection mechanism;Support base 2 is fixedly installed at the bottom of workbench 1, the top of workbench 1 is fixedly installed automatic feeder 3, the top of workbench 1 is fixedly installed bed body 4, the right side of workbench 1 is fixedly installed conveyer belt support 5, the top of workbench 1 is installed with length detection mechanism for detecting the length of material conveying, the right side of workbench 1 and the outside of conveyer belt support 5 are installed with offset detection mechanism for detecting material arching or offset.
[0026] The device adopts automatic feeder 3 with intermittent conveying function, which can accurately send the materials to be stamped into the stamping progressive die according to the set interval, and provides the material input basis for misfeed detection. The inside of bed body 4 is fixedly installed with hydraulic cylinder for driving the downward pressure of upper die 7.
[0027] In one embodiment, as shown in Figure 2 And Figure 3 The length detection mechanism includes lower die 6 fixedly installed on the top of workbench 1, the inside of bed body 4 is connected with upper die 7 through hydraulic cylinder, telescopic column 8 is connected between lower die 6 and upper die 7, material belt 9 communicated with the output end of automatic feeder 3 is slidingly connected on the top of lower die 6, material body 10 is placed on the top of material belt 9, ratchet wheel and pawl mechanism for receiving conveying information is rotatably installed on the top of lower die 6.
[0028] The bed body 4 drives the upper die 7 to press down through a hydraulic cylinder, and the telescopic column 8 is internally provided with a hydraulic damper for buffering the stamping force of the upper die 7 and the lower die 6. Under the buffering action of the telescopic column 8, the lower die 6 and the upper die 7 are attached, so as to perform the stamping work on the material body 10 on the material belt 9.
[0029] The ratchet pawl mechanism comprises a ratchet 11 rotatably installed on the top of the lower die 6, a rotating support 12 fixedly installed on the top of the workbench 1, and a pawl 13 rotatably installed on the rotating support 12 and abutting against the external ratchet teeth of the ratchet 11. A trigger unit for providing a signal is fixedly installed on the rotating shaft of the pawl 13.
[0030] The trigger unit comprises a trigger lever 14 fixedly installed on the rotating shaft of the pawl 13, a trigger 15 fixedly installed on the top of the workbench 1 and matched with the trigger lever 14, and a push lever 16 fixedly installed on the outside of the material body 10 and matched with the ratchet 11.
[0031] A torsion spring is arranged at the rotating connection position of the rotating support 12 and the trigger lever 14. After the ratchet 11 pushes the pawl 13 to rotate each time, the pre-tightening force of the torsion spring is opposite to the rotating direction of the pawl 13, so as to ensure that the pawl 13 is reset after each action. The end of the trigger lever 14 is provided with a pressing protrusion matched with the trigger 15. With the movement of the material belt 9 conveying the material body 10, the pawl 13 moves a fixed pitch on the ratchet 11 each time the automatic feeder 3 pushes the material belt 9. While the pawl 13 rotates, the trigger lever 14 also rotates and presses the trigger 15 to trigger the signal. If the feeding length is insufficient, the pawl 13 cannot reach the predetermined tooth position, and the trigger 15 cannot be triggered. If the feeding length is too long or insufficient, the trigger lever cannot normally trigger the signal. After receiving the signal, the press machine controller controls the press machine to stop working, so as to prevent the mold from being damaged.
[0032] In one embodiment, as shown in Figure 4 the offset detection mechanism comprises a sliding support 17 fixedly installed on the right side of the workbench 1, the sliding support 17 is located outside the conveying belt support 5, a mounting support 18 is slidingly installed on the outside of the sliding support 17, and a detection unit for detecting the position of the material is fixedly installed on the top of the mounting support 18.

[0034] The proximity switch 20 is arranged at a position horizontally to the material body 10, and the mounting bracket 18 is provided with a bolt for fixing the position. The position of the proximity switch 20 can be adjusted by sliding the mounting bracket 18 on the outside of the sliding bracket 17 up and down. When the material body 10 carried by the material belt 9 approaches the proximity switch 20, the proximity switch 20 detects the position of the material body, and outputs an abnormal signal if there is a deviation, and the punch press is immediately stopped.
[0035] The above embodiment discloses a stamping progressive die misfeed detection device, wherein as the material belt 9 carries the material body 10 to move, the automatic feeder 3 pushes the material belt 9 once, and the pawl 13 moves a fixed pitch on the ratchet wheel 11. When the pawl 13 rotates, the trigger lever 14 also rotates and presses the trigger 15 to trigger a signal. If the feeding length is insufficient, the pawl 13 cannot reach the predetermined tooth position, and the trigger 15 is not triggered. When the feeding length is too long or insufficient, the trigger lever 15 cannot normally trigger the signal, and the press machine controller controls the press machine to stop working, so as to avoid damage to the die. The position of the proximity switch 20 can be adjusted by sliding the mounting bracket 18 on the outside of the sliding bracket 17 up and down. When the material body 10 carried by the material belt 9 approaches the proximity switch 20, the proximity switch 20 detects the position of the material body, and outputs an abnormal signal if there is a deviation, and the punch press is immediately stopped.

Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
