Background

Cold heading machines are stamping machines used in mechanical manufacturing to shape a material into a desired shape (typically "steps") without any change to the material (mainly softening or hardening). One end of the crankshaft is provided with a pair of bevel gears, the driven bevel gear shaft of the crankshaft is provided with a cam device, and the roller shaft of the driven roller of the cam device is vertically provided with a scissors sliding block. The invention overcomes the defects of the prior art, has small running friction coefficient and impact force among all parts of the feeding and cutting mechanism, ensures that the equipment runs stably, effectively reduces running noise, greatly improves the product quality and the production rate, and is often used for processing and manufacturing fasteners and connecting pieces (such as bolts, nuts, screws, rivets and the like).

The cold heading machine usually runs continuously and at a high speed in the machining process, and the cold heading machine is usually formed by adopting a mold, so that the abrasion of the mold is continuous, in order to ensure that the quality of a product is stable in a certain range, a certain number of screws need to be machined, and then a new mold needs to be replaced, but the abrasion condition of the mold can be calculated according to the deviation condition of the screws and the design size after the machined screws are measured and observed in the traditional cold heading machine production, but a certain number of defective screws are usually produced at the moment; in order to avoid the defective screws being treated as waste products, enterprises generally sell the defective screws to some less-demanding application places after screening and grading the defective screws, but the prices of the defective screws are very low, so that the defective screws are undoubtedly lost to the enterprises.

In addition, the cold heading machine needs to be inspected and maintained after being started for a long enough time, but the existing cold heading machine is usually inspected and maintained after the problem of wire outgoing in the production process, so that the small problem is usually expanded to the big problem.

In addition, the most direct phenomenon of the cold heading machine after the wire is exhausted or the cold heading machine breaks down is that the screw cannot be output from the outlet of the cold heading machine or the screw output speed is reduced, and the problems are difficult to find in time in the conventional production process of the cold heading machine due to the fact that one person has multiple machines, so that the die or the machine is damaged.
