Mark engraving device

Abstract

The invention provides a mark engraving device. A movable upper cover is arranged above a character head slot at one side of a base and is connected to one side face of the base through a hinge in a hinging manner, the other side face of the base is provided with a shaft seat which is connected to a flat lower end of a movable screw through a connecting shaft, the upper end of the movable screw is matched with a nut, the side face of the nut is welded with a right-angled rotating rod, the other end, opposite to the hinge hinged end, of the movable upper cover extends out of the character head slot, the end part of the end, extending out of the character head slot, of the movable upper cover is in a forked shape, and a groove in the middle of the forked-shape part is matched with the upper end of the movable screw. According to the mark engraving device, the connection manner of the original upper cover is changed into hinge connection, in such a way, fonts can be frequently replaced, and the detaching time is largely saved. Bolt and nut connection is adopted at the right side, and through screwing up a spanner on the nut, the upper cover can be tightly pressed, so that the phenomenon of font fuzz caused by looseness of character heads during marking can be avoided. The mark engraving device belongs to a mechanism suitable for engraving permanent marks after an end part of which the material diameter is greater than 30mm is forged to be flat.

Description

technical field [0001] The invention belongs to a marking and engraving device for mechanical products, in particular to a marking and engraving device. technical background [0002] With the improvement of the quality of spring products in the railway market, the traceability of spring products is particularly important. In particular, in-road products need to pass the CRCC certification to engrave the serial number on the spring end ring of the passenger car so that the spring can be traced when quality problems occur. Therefore, each OEM requires the manufacturer to permanently mark the serial number of the spring. Due to the previous identification Only engraving the manufacturer and the year, month and month of production can be solved by changing the prefix once a month. However, due to the increase in the engraving of the serial number, since the serial number of each spring is not unique, workers need to manually tap the spring end ring in the hot state for engraving...

AI Technical Summary

Problems solved by technology

In particular, in-road products need to pass the CRCC certification to engrave the serial number on the spring end ring of the passenger car so that the spring can be traced when quality problems occur. Therefore, each OEM requires the manufacturer to permanently mark the serial number of the spring. Due to the previous identification Only engraving the manufacturer and the year, month and month of production can be solved by changing the prefix once a month. However, due to the increase in the engraving of the serial number, since the serial number of each spring is not unique, workers need to manually tap the spring end ring in the hot state for engraving. Printing the serial number causes the serial number to be engraved irregularly, and the fonts are overlapped and reversed, which is very easy to cause human error and increase the labor load and risk factor. Therefore, this improvement is necessary.
