Metal spacer bender bending device

Abstract

The invention discloses a metal spacer bender bending device. The bending device comprises a turntable, a locking block, a rotary cylinder, a fixing block, guiding shafts, a pressure plate, a pressing air cylinder and a baseplate, wherein the fixing block is used to fix one end of the guiding shaft, the pressing air cylinder is fixed on the base of the pressing air cylinder, the guiding shaft is connected between the fixing block and the base of the pressing air cylinder, an arc groove is arranged on the turntable corresponding to the guiding shaft; another cantilever type guiding shaft is connected on the base of the pressing air cylinder, one end of the cantilever type guiding shaft is fixed on the base of the pressing air cylinder, the other end is close to the surface of the turntable, the position of the turntable corresponding to the cantilever type guiding shaft is complanate so that no groove is needed to be arranged on the turntable, and the pressing part of the turntable and the pressure plate are both smooth planes so as to avoid that the spacers deform when being pressed at the positions; and the widths of the metal spacing frames are ensured to be equal, the bending parts are smooth and flat, and the bending effect can reach the specified requirements and the use requirements.

Description

technical field [0001] The invention relates to the technical field of hollow glass auxiliary production equipment, in particular to a bending device of a semi-automatic metal spacer bending machine. Background technique [0002] In China, trough-aluminum insulating glass occupies the vast majority of the market, and the support frame for making trough-aluminum insulating glass is basically made by splicing four sections of aluminum strips or stainless steel strips, and the four corners are fixed by plastic corner inserts. The metal frame made by this method has shortcomings such as short service life and poor sealing performance. For this reason, someone invented a metal spacer bending machine, which can make various shapes of convex polygonal aluminum frames through continuous bending of a single metal spacer, which overcomes the shortcomings of spliced ​​metal frames, and many advantages make it an energy-saving hollow frame. Indispensable equipment in the glassmaking pr...

Problems solved by technology

Since there are two arc-shaped grooves corresponding to the two guide shafts on the turntable, it is very easy to press the spacer bar into the arc-shaped groove during the bending process of the metal spacer bar to cause deformation and bulge, which will affect the appearance of the metal frame at least , the bending width deviation exceeds 0.3mm, resulting in the inability to complete the gluing work in the next butyl rubber coating process due to the ultra-wide spacer frame, which can not meet the regulations and use requirements, resulting in waste of materials
