を行うようにした装置に関する。[Detailed description of the invention] (Field of industrial application) The present invention is designed to perform the final step immediately after the completion of heading in the process of forming cup-shaped, other hollow or solid cylindrical products using a multi-stage former. The present invention relates to a device that is used to inspect and measure the amount of deviation of a cylindrical product and detect defective products.

できないという問題がある。(Prior Art and Problems) When a cup-shaped product is forged using a multi-stage former, if the position of the hollow hole is displaced with respect to the axis, local thickness deviation in the circumferential direction will occur, resulting in a defective product. Also, in the case of a solid cylindrical product having a head concentrically integrated with the tip of the shaft, the head may be deviated, resulting in a defective product. Such defective products are inspected and measured one by one after forging, but these operations are extremely troublesome. However, since the products to be pressed have a wide variety of shapes, sizes, types, etc., there is a problem in that a single inspection machine cannot perform a complete inspection.

The technical problem is to enable easy inspection and measurement of any type of product, such as a finished product or other hollow or solid cylindrical product.

In a home machine in which a cylindrical product 1 is forged by sequentially forging a metal material using a plurality of dies 3 arranged in a horizontal line and a punch 5 provided in front of each of the dies so as to move forward and backward relative to each other. In a detection device for cylindrical products, a gauge pin 11 made of a round bar body is attached to elastic rings 12, 1 so as to have a free movement distance in the circumferential direction in a punch case 10 which is the final forging process.
3, and the corresponding die side is provided with a product receiving part 21 consisting of a hollow recess for receiving the product 1 in the die case 20, and an annular part 22 projecting forward on the front periphery thereof. , a sensor 23 for detecting the amount of displacement of the gauge pin 11 is attached to the annular portion 22 in an axial direction.

させられる。Preferably, a plurality of the sensors 32 are provided at equal or unequal intervals around the circumference. Further, the gauge pin 11 can be held so as to be retractable against the bias of the spring 14. (Function) The cylindrical product 1 formed in the heading section is transferred to the transfer chuck 2.
When the product 1 is carried to the final position immediately before the die case 20 by the product 5, the ram 26 moves forward and the product 1 is pushed into the receiving portion 21 of the die case 20 by the gauge pin 11. At this time, if the thickness of the cylindrical part of the product 1 is uneven as shown in FIG. 3, the gauge pin 11 is pushed and displaced toward the thinner side depending on the degree of thickness unevenness, so Since the proximity position of the disk body 24 above and below or to the left and right of the sensor 23 changes, the amount of displacement thereof is detected. If this amount of displacement exceeds the allowable value, the command device immediately issues a command to the control device to stop the machine.

おける不良品発生を防ぐことができる。 Immediately after forging is completed by the forging section, and before taking the cylindrical product out of the machine, it is pushed directly into the receiving section on the die side with a gauge pin to inspect and measure the degree of uneven thickness, and the sensor detects defective products. The machine can then be stopped immediately to prevent future defective products.
