Frame pressing machine with corner pressing assemblies

Abstract

The invention discloses a frame pressing machine with corner pressing assemblies. The frame pressing machine with the corner pressing assemblies comprises the four corner pressing assemblies. Each corner pressing assembly comprises a sliding frame, wherein the sliding frame comprises a sliding face, a fixed frame erected on the sliding frame and a corner supporting table arranged on the front portion of the fixed frame; the fixed frame is provided with a lever base pivoted to the middle of a lever; the tail portion of the lever is controlled by a corner pressing air cylinder; the tail portion of the corner pressing air cylinder is pivoted to an air cylinder base fixed to the sliding face; the head portion of the lever is pivoted to one end of a rocking block; a pressure block is pivoted to the other end of the rocking block. The corner pressing assemblies are provided with a series of pivot joint structures, so that the pressure blocks synchronously and horizontally move along with the splicing area of a long frame and a short frame in the frame installing process, and the problem that the pressure blocks rotate and the pressure blocks make point or line contact with the splicing area to cause indentation and other product surface problems is avoided.

Description

technical field [0001] The invention relates to the technical field of framing equipment, in particular to a frame pressing machine with a pressing angle assembly which prevents improper pressing angle from damaging the product surface. Background technique [0002] A frame pressing machine is a device that can be used to assemble glass and frames. The appearance of the assembly between the long frame and the short frame generally requires the splicing area to be as tight as possible. Therefore, after the long frame and the short frame are assembled in place, the local corners of the splicing area must be pressed and squeezed, which is usually done by pressing the corner components. , the principle of action is that the lever mechanism transfers the thrust of the pressure angle cylinder to the pressure of the briquetting block, and the briquetting block and the corner support table together limit the horizontal height of the splicing area. After the height positioning is com...

Problems solved by technology

The appearance of the assembly between the long frame and the short frame generally requires the splicing area to be as tight as possible. Therefore, after the long frame and the short frame are assembled in place, the local corners of the splicing area must be pressed and squeezed, which is usually done by pressing the corner components. , the principle of action is that the lever mechanism transfers the thrust of the pressure angle cylinder to the pressure of the briquetting block, and the briquetting block and the corner support table together limit the horizontal height of the splicing area. After the height positioning is completed, the splicing area will continue to move in a small range to achieve It really achieves a tight seam. However, the pressure block is limited by the lever connection and cannot move in parallel with the splicing area. If the pressure block rotates, its contact with the splicing area may become point contact or line contact, and the increased pressure will cause product surface crush
