Automatic adjusted 90-degree angle bending forming mechanism

Abstract

The invention disposed an automobile adjusted 90-degree angle bending forming mechanism. The automobile adjusted 90-degree angle bending forming mechanism comprises a fixed base plate. A right lower die fixed block is fixed to the right portion of the top surface of the fixed base plate. A slant wall face is formed on the top surface of the left end of the right lower die fixed block. A lower dieadjusting block is located on the left end of the right lower die fixed block. The bottom surface of the lower die adjusting block is a bevel, and the bevel is pressed on the slant wall face. The topsurface of the lower die adjusting block is an upper slant wall face. A left vertical plate is fixed to the top surface of the left portion of the fixed base plate. An upper supporting plate is fixedto the top surface of the left vertical plate. A hold-down cylinder is fixed to the top surface of the upper supporting plate. The right side of the bottom end of a punch pin is provided with an arc-shaped chamfered part. The arc-shaped chamfered part is pressed on the upper slant wall face. The punch pin is movably connected so that the automobile adjusted 90-degree angle bending forming mechanism can be used for machining plates to be bent with different similar thicknesses and can ensure the bending effect.

Description

Technical field: [0001] The invention relates to the technical field of electronic hardware manufacturing, and more specifically relates to a 90° angle bending forming mechanism with automatic adjustment. Background technique: [0002] When the existing metal plate is stamped and bent at 90 degrees, the distance between the punch and the fixed block of the lower die needs to be equal to the thickness of the bent plate, so as to ensure that the surface of the bent part will not be worn or damaged. Deformation, etc., however, it can only adapt to this type of stamping plate. When the thickness of some stamping plates is 0.1mm or even 0.2mm greater than the specified stamping plate, the surface of the stamping plate will be damaged and deformed, affecting the finished product. At this time, only Replacement of punches and other structures, and punches need to be replaced every time stamping plates with different thicknesses are used, which is troublesome to install and disassem...

[0002] When the existing metal plate is stamped and bent at 90 degrees, the distance between the punch and the fixed block of the lower die needs to be equal to the thickness of the bent plate, so as to ensure that the surface of the bent part will not be worn or damaged. Deformation, etc., however, it can only adapt to this type of stamping plate. When the thickness of some stamping plates is 0.1mm or even 0.2mm greater than the specified stamping plate, the surface of the stamping plate will be damaged and deformed, affecting the finished product. At this time, only Replacing punches and other structures, and punches need to be replaced every time stamping plates with different thicknesses are used, which is troublesome to install and disassemble, which greatly reduces production efficiency
