Die head of extrusion die capable of embossing on adjacent surfaces of section bar

Abstract

The invention relates to a die head of an extrusion die capable of embossing on adjacent surfaces of a section bar. A first embossing device and a second embossing device are arranged on a forming plate, embossing rollers of the two embossing devices are arranged on the same connection surface of the forming plate, a protruding part which passes through the end portion of an adjacent end of the second embossing roller and extends to the end portion of the adjacent end of the first embossing roller is arranged on a fixing support at the adjacent end of the first embossing roller, a fixing support at the adjacent end of the second embossing roller is arranged on the other side of the protruding part, and a through hole which is used for leading a pivot at the adjacent end of the second embossing roller to pass through and is in a long strip shape in the direction perpendicular to the second embossing surface is arranged on the lateral wall of the protruding part. Due to the fact that the two embossing rollers are arranged on the same connection surface of the forming plate, the die head of the extrusion die is compact in structure, cannot add the thickness of the forming plate, can ensure normal and stable production of the section bar and does not increase the difficulty in traction operation of the section bar.

Description

technical field [0001] The present invention relates to an extrusion die head capable of embossing adjacent surfaces of a profile. Background technique [0002] The single surface embossing device for profiles has a structure as disclosed in the patent document CN200974329Y. The embossing roller and the pivot fixing brackets at both ends are fixed in the installation groove at the outlet end of the forming plate of the extrusion die head, and the forming plate is provided with Adjusting device for adjusting the vertical displacement of the fixed support relative to the embossing surface. Due to the special structural requirements of some profiles, such as figure 1 As shown, the two adjacent surfaces 11, 12 of the profile 1 need to be embossed as visible surfaces. If the original method is used, it is impossible to simply stack two embossing devices on the same plane, and they will interfere with each other when they are installed; Intersecting, in order to avoid mutual in...

AI Technical Summary

Problems solved by technology

If the original method is used, it is impossible to simply stack the two embossing devices on the same plane, and they will interfere with each other when they are installed; Intersecting, in order to avoid mutual interference on the intersecting surfaces of the two embossing rollers, the two embossing devices are arranged alternately in two layers in different spaces. The disadvantage is that the distance between the die head and the setting die is enlarged, which will cause The profile production is unstable, easy to deform, and the depth of the surface pattern cannot be effectively controlled
