Adjustable rotation auxiliary roller device for cold bend forming machine

Abstract

The invention discloses an adjustable rotation auxiliary roller device for a cold bend forming machine. An axial key groove is formed in an upper shaft. A fixing sleeve is fixed to the upper shaft through a flat key matched with the key groove. A rotating seat is arranged on the fixing sleeve in a sleeving mode and is further limited through a stopping step arranged on one side of the fixing sleeve, and the other side of the rotating seat is flush with the axial end of the fixing sleeve and is further positioned through a compressing sleeve. The fixing sleeve is positioned and locked through alocating pin which penetrates through the stopping step and a rotating seat pin hole in the axial direction. A plurality of sets of unsymmetrical auxiliary roller arms are fixed to the outer side ofthe rotating seat in the circumferential direction through screws. Auxiliary rollers are fixed to the tail ends of the auxiliary roller arms through arc-shaped roller shafts. The positions, located onthe outer side of the fixing sleeve and the outer side of the compressing sleeve, of the upper shaft are sleeved with shaft sleeves used for adjusting the left and right position of the auxiliary roller device correspondingly. The outer side axial ends of the shaft sleeves are locked through gland nuts respectively. According to the adjustable rotation auxiliary roller device for the cold bend forming machine, the specification replacement time is short, operation is convenient, and the adjustable rotation auxiliary roller device can be suitable for quickly switching the auxiliary rollers ofdifferent bottom widths and different thickness specifications; and moreover, the structure rigidity is good and formation is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of forming devices in the cold-bending industry, and in particular relates to an adjustable rotating auxiliary roller device for a cold-bending forming machine. Background technique [0002] At present, there are two main structural forms of the auxiliary roll device used in the cold roll forming machine: one is auxiliary forming between passes, installed on the side plate or the side of the archway, when changing the plate type or adjusting the specification, Manual wire adjustment is required, and there is no benchmark, and the error is often large. For its structure, please refer to the attached figure 1 ; The other is the auxiliary roller device designed above the pass, which is installed between the upper and lower shafts. When changing the plate type or adjusting the specification, the lower shaft roller is used as the reference. The adjustment is relatively simple and the error is small. For its struc...
