However, the machine can only hold the same type of font, and when producing different types of workpieces, the font must be replaced repeatedly, which is very troublesome and affects production efficiency.

Contents of the invention

Aiming at the existing deficiencies, the present invention provides a two-way die head of a printing machine, on which various types of character patterns are installed, which can be replaced in time when different types of workpieces are converted, and can be operated immediately without debugging. Affect continuous production and improve production efficiency.

In order to achieve the above technical goals, the technical solution adopted to solve the technical problems is: a two-way die head, including a bracket, a pillar, and a die head. The bracket is provided with a longitudinal seat plate. In the guide rail of the plate, the top of the pillar is connected to the screw, and the screw is connected to the hand wheel. The pillar is provided with a crossing shaft hole, and the side wall of the shaft hole is provided with an axial positioning groove. There are font controls at both ends of the die head. In the font control, there are adjusting screws symmetrically around the font control to adjust the flatness of the font. The transverse axis of the die head is connected in the shaft hole of the pillar. The positioning block of the die head is embedded in the positioning groove, and the locker fixes the die head. It is integrated with the pillar and the two axes of the die head and the pillar are parallel to realize the work of the unit font control. The die head is suspended above the rolling plate that distributes the workpiece, and the font of the font control corresponds to the rolling groove of the rolling plate.

The rolling plate is connected to a rotating shaft, and the rotating shaft is driven to rotate by a variable speed motor.

After adopting the above-mentioned structure, the support bracket of the pillar is fixed in the guide rail of the seat plate by means of the pressure plate and bolts, so that the pillar will not shift when adjusting the pressure distance of the font control, and keep the pillar in a vertical state to ensure that the plane of the font and the rolling plate The plane of the rolling groove is parallel, and the surface of the font and the workpiece are evenly pressed. Of course, the pillar can only be moved up and down by the handwheel during debugging, and the pillar is fixed during work. The font controls at both ends of the die head are equipped with different types of fonts. According to the production situation, the required font controls are replaced. The positioning block of the die head is embedded in the positioning groove, so that the die head and the pillar are fixed on the parallel axis. The font control of the head is also vertical to the plane of the rolling groove, so as to realize the operation of the unit font control. Adjusting screws are symmetrically arranged around the font control, which is convenient and labor-saving to adjust the flatness of the font.

The existing small-scale drill bit production enterprises, because of the fast production speed of the printing machine, one printing machine is equipped with multiple drill bit production lines. To replace different types of fonts, it takes a long time to change the molds and debug. The die head of this technology is bidirectional. The font controls at both ends of the die head are first equipped with various types of fonts that have been debugged. When converting products, select the corresponding fonts, which can be produced and converted immediately after being connected and fixed by the locker. The speed is fast, does not affect continuous production, and improves production efficiency.
