The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1, the utility model is applied on the machine for shrinking, and the workbench of this machine for shrinking is provided with draw mechanism and clamping device.Clamping device is positioned on the base plate 1; Comprise clamping cylinder 2, be used for upper clamp formwork 3 and lower clamp formwork 4 pipe fitting clamping to be processed; Vertically be provided with four symmetrically arranged in twos guide upright posts 5 on the base plate 1; The top of guide upright post 5 is fixed with clamping seat upper plate 6; Above-mentioned clamping cylinder 2 is fixed on the clamping seat upper plate 6, also is equipped with sliding clamp 7 on the guide upright post 5 between clamping seat upper plate 6 and the base plate 1, and sliding clamp 7 is equipped with a clamping seat 8 with base plate 1 side in opposite directions; Upper clamp formwork 3 is fixedly installed on respectively on the clamping seat 8 of sliding clamp 7 and base plate 1 with lower clamp formwork 4, and the piston rod outer end of clamping cylinder 2 is passed clamping seat upper plate 6 backs and is connected with sliding clamp 7 and also can drives clamping seat upper plate 6 and move up and down along guide upright post 5.
Draw mechanism comprises master cylinder 9, draw die holder 10, is used for fixing the upper slide rest 11 of draw die holder 10 and drives the saddle 12 that upper slide rest 11 related draw die holders 10 are pressed to the pipe fitting port; Pipe-reduction mold is installed on the draw die holder 10; The front portion of saddle 12 is connected with upper slide rest 11 through a dovetail slide rail; This slide rail is perpendicular to the direction of feed of saddle 12, and the rear portion of saddle 12 is connected with the piston rod of master cylinder 9, by the feeding and the rollback of master cylinder 9 control saddles 12.During this enforcement is upright; There are two draw die holders 10 in every group of draw mechanism; Therefore need a die change oil cylinder 13 to carry out the replacing of draw die holder 10; Die change oil cylinder 13 is installed on the sidewall of saddle 12, and its piston rod is connected with upper slide rest 11, can drive upper slide rest 11 related draw die holders 10 and move back and forth along above-mentioned slide rail.
