Description

Metal workpiece marking printing device

The present invention provides a metal workpiece marking printing device that is associated with a device for printing on metal.

According to the diversification of technology development and demand, the construction method is not limited to the traditional mud brick building. The steel construction system with rapid construction and sufficient building strength can be seen everywhere. The main material of the steel construction is through the steel. As the main building core, after the general steel is cut to the required size, it must be identifiable on the surface of the steel, so that it can be assembled correctly according to the design drawing in the assembly process; Some of the above methods are marked by paint or ink directly on the surface of the steel. However, in general, the steel needs to be galvanized and rust-proof before assembly, that is, the steel must be degreased, pickled, detergent and hot. The immersion galvanizing process can ensure the corrosion resistance of the steel. The marking made of paint or ink will cause a large amount of wear after a series of rust-proof treatments, and the marking will become inconspicuous or inaccurate, which may result in assembly. The judgment at the time of construction is wrong, which affects the subsequent construction; in addition, some operators make the mark on the surface of the steel by etching. , And the depth of the label made by etching is too light, so in the course of the rust-proofing treatment, dip coating step of coating will make filled into the recess etching produced in the same manner and cause marked obvious pins The lack of clarity; and once the depth of the etching is to be changed, the construction time will be greatly increased, resulting in a substantial increase in production costs; even, in order to strengthen the surface strength of the steel, a sandblasting process will be carried out, which is disclosed by ink or etching. The method of making the mark will be more blurred and difficult to identify after sand blasting. In addition, in addition to the way of marking with ink or etching, there are also ways for the manufacturer to emboss by pushing the rotatable dial. The label is generated, and the main label is to generate the plural label by driving the spindle displacement, rotation and embossing of the single dial. When the number of labels is large, the dial must be rotated to the desired type before each imprint. Once the embossing is performed, the dial must be rotated again to change the typeface. The efficiency of labeling is extremely low, and the overall structural strength needs to be strengthened. In view of this, the inventors have devoted themselves to researching and further conceiving, and after many trials and developments, they finally invented. A metal workpiece marking printing device is produced.

The invention provides a metal workpiece marking printing device, the main purpose of which is to improve the loss of the marking of the conventional metal workpiece due to post-processing and loss or blurring.

To achieve the foregoing objective, the present invention provides a metal workpiece marking printing device, comprising: a device holder having a plurality of device seat slide rails, each of the device seat slide rails extending along a first direction; a sliding seat for a plurality of sliding seats The slider can be slidably sleeved on each of the device seat rails, so that the slider can be displaced in the first direction, and the vertical first direction is defined as the second direction; a printing roller group including the complex digital disk and a support a mandrel extending in the second direction and penetrating the dials and pivotally disposed on the carriage, and each of the dials a plurality of printing portions are disposed on the periphery, each of the printing portions is a convex type; a driving unit includes a servo motor corresponding to the number of the dials to respectively drive the respective dials; an imprinting unit including a driving source and a push The driving source is fixedly disposed on the device seat, and the driving source is coupled to drive the pushing member to be displaced in a first direction, and the pushing member faces each of the dials.

The invention wears a digital disk through a printing roller set with a single supporting mandrel, and each of the dials is driven by a driving source to change the required printing words, and the effect of changing the typeface is high and convenient to use, and the printing unit is The way in which the pressure is pushed against the dial to create a recessed mark can produce a mark that is not easy to be erased, improving the accuracy and convenience of subsequent construction.
