Description

Road rudder {IMPACT MARKING MACHINE}

The present invention relates to a rod rudder, and more particularly, to a rod rudder for automatically marking a unique number, a production number, a company name and a logo on a rod-shaped product.

In general, the parts used in the mechanical field, automobile or aviation field, and various industrial sites use the rudder device for the effective management of the corresponding parts, as well as the unique serial number of the production date, the manufacturer, etc. Marking is indicated by the method.

Usually, two methods are used to engrav a specific pattern or letter on the surface of solid materials such as metal, stone, plastic and wood.

For example, the tip of the tool is reciprocated up and down, and is divided into a rudder method in which a desired shape is inscribed on the surface of the marking object, and a press-in method in which the end of the tool is pressed after inserting a certain depth of the marking object. do.

The difference in this method affects the feel or shape of the marked pattern, which is used according to the material, the type of the rudder tool, the type of the intaglio pattern, and other environments.

In particular, in the case of the rudder method, unlike the press-in method, working with the rudder angle by the compression of the spring is possible without the load on the product, and the constant rudder has the advantage of always obtaining a uniform quality of the desired depth.

In addition, the jig can be attached to increase the efficiency of the work, and according to the attachment of type and tools, the product's unique number and production number, the company name and logo can be used. That's the way.

However, since the conventional rudders are composed of a vertical structure in which the rudder tools are operated by operating the rudder tool from the top to the bottom, the rudder angle is difficult for long rod-shaped products.

In addition, the conventional rudders have a disadvantage in that workability and productivity fall due to the rudder work being performed depending on the manual operation of the worker, and there is a difficulty in ensuring uniform and constant rudder quality.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 are a perspective view, a front view and a plan view showing a rod rudder according to an embodiment of the present invention.

As shown in Figures 1 to 3, the rod rudder is made of a structure that can effectively perform the rudder operation suitable for long rod-shaped products using a horizontal rudder method.

To this end, the rod rudder includes a rudder body 10 as a means for installing components such as the marking actuator assembly 11, the product fixing jig 12, and the like.

The rudder body 10 includes a base plate 29 of an upper end, and the marking actuator assembly 11, the product fixing jig 12, and the like may be installed on the base plate 29.

For example, a marking actuator assembly 11 may be installed on the left side of the base plate 29, and a product fixing jig 12 may be installed on the opposite side of the base plate 29.

In addition, the rod rudder includes a marking actuator assembly 11 as a means for providing power for the rudder operation.

The marking actuator assembly 11 serves to provide power for the rudder angle operation of the type 14 by cylinder operation and spring force.

To this end, the marking actuator assembly 11 is installed on one side of the base plate 29 in the rudder body 10, and this marking actuator assembly 11 has a cylinder-side rack 38 to generate power. And a marking cylinder 17 for providing a compression force of the spring, a driving shaft 13 for providing a hitting force to the type 14 and the type holder 15, and the like.

For example, a pin (not shown) engaged between a ball (not shown) and a spring (not shown), a drive shaft side rack (not shown), a cylinder side rack 38 and a drive shaft side rack (not shown), and the like. Marking head 18 having a built-in is installed on the base plate 29, the marking cylinder 17 of the horizontal posture toward the rear is connected to the lower end of the marking head 18 is installed in this way at the top of the marking cylinder The drive shaft 13 which can be moved back and forth while being horizontally arranged parallel to the axis of 17 is provided through.

Accordingly, when the cylinder-side rack 38 is retracted according to the backward operation of the marking cylinder 17, pinions (not shown) and drive shaft-side racks (not shown) built in the marking head 18 are associated with this. During this operation, the spring (not shown) is compressed at this time, and the ball (not shown), which restrains the compression state of the spring (not shown), is pulled out and the spring (not shown) is instantaneously expanded, thereby driving the drive shaft 13 ) Also momentarily rapid forward movement, which results in a momentary impact on the type 14 working with the drive shaft 13, thus marking the product.

Here, the detailed configuration of the marking cylinder 17, the marking head 18, etc. belonging to the marking actuator assembly 11 and the specific operation mechanism (for example, the operation of impacting the type with the spring force for the steering angle) are common. Since the configuration and operation mechanism of a known actuator means such as an impact rudder commonly used in the rudder device are the same, the description thereof will be omitted.

In particular, the marking actuator assembly 11 provided in the present invention includes means for adjusting the marking depth for the product.

To this end, the pressure adjusting nut 19 and the pressure fixing nut 20 are sequentially coupled to the rear end of the drive shaft 13 installed horizontally on the marking head 18, and at this time, the pressure adjusting nut ( 19) and by adjusting the compression degree of the spring (not shown) through the operation of the pressure fixing nut 20, it is possible to adjust the steering force transmitted through the drive shaft (13).

For example, when the pressure adjusting nut 19 is rotated clockwise while being tightened (advanced) while the screw of the pressure fixing nut 20 is loosened, a spring (not shown) embedded in the marking head 18 is Since it becomes a relatively more compressed state, it is possible to deepen the degree of marking by increasing the angular force such that the elastic force applied to the drive shaft 13 can be increased by the increased spring force at this time.

On the contrary, when the pressure adjusting nut 19 is rotated counterclockwise in the state of loosening the screw of the pressure fixing nut 20 (backward), the spring (not shown) becomes a relatively less compressed state. By weakening the spring force, the elastic force exerted on the drive shaft 13 can be reduced such that the angle of attack can be reduced and the degree of marking can be made shallow.

Then, if the pressure fixing nut 20 is tightened again after the adjustment of the pressure adjusting nut 19, the adjusted state at this time can be set.

As such, since the marking depth can be adjusted by adjusting the punching force through the manipulation of the pressure adjusting nut 19 and the pressure fixing nut 20, a general metal product as well as a product having a thin thickness such as paper, eg For example, it is possible to mark various materials such as metal, plastic, wood, paper, general castings, and die casting products.

In addition, the rod rudder includes a product fixing jig 12 is installed on the rudder main body 10 as a means for holding the rod-shaped product 110 in a horizontal position.
