The double linkage mechanism of aforesaid crank press, wherein said rolling wheel support lower end is provided with lead, and described lead stretches in the pilot hole of roller support.
Because adopted above technical scheme, the stamping machine of the utility model band double linkage mechanism has following beneficial effect:
The utility model is simple in structure, use is easy to maintenance, because the bottom dead centre of cam and bent axle bottom dead centre can be realized the function of first flanging after-drawing not on same position; By changing cam outline radius of curvature, just can realize the technological requirement of different dwell times.As long as change the adjustment packing ring of different-thickness, just can adjust the diel closed height; Change the adjustment pad of different-thickness between jumper bar and the drift, just can adjust the distance that drift stretches out the slide block bottom surface, satisfy the requirement of various different stretch or Sheet Metal Forming Technology.The ad hoc cushion blocking of the utility model can play cushioning effect to descending jumper bar, and can reduce the descending noise of connecting rod.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises bent axle 1, connecting rod 2, jumper bar 3, drift 4, cam 5, roller 6, slide block 7, rolling wheel support 16, connecting rod 2 upper ends are hinged by connecting rod bearing shell 8 and maneton, slide block two side rails 71 flexibly connect with the track base 19 that is fixed on crank press fuselage 20 inboards, cam 5 is separately fixed at the maneton both sides by flat key, holding screw, and roller 6 leans with cam 5 downsides respectively.Rolling wheel support 16 is separately positioned on slide block 7 both sides, and cam 5 is hinged by roller pin 15 and rolling wheel support 16 upper ends.Fixedly connected with roller support 18 by brace 17 respectively in rolling wheel support 16 both sides, fixedly connected with slide block 7 upsides respectively by securing member in roller support 18 upper ends, rolling wheel support 16 lower ends put in the roller support 18, rolling wheel support 16 lower ends are provided with lead 161, and described lead 161 stretches in the pilot hole of roller support 18.Connecting rod 2 lower ends that are arranged on slide block 7 centres are hinged with the bearing of jumper bar 3 upper ends by link pin 9 and pair of bearings 10, jumper bar 3 middle parts are installed in the fairlead 13 at slide block 7 middle parts by the cushion blocking 11 and the pad 12 that resets, jumper bar 3 lower ends are threaded with fixed cover 14, nut 25 is connected with jumper bar 3 lower ends, is bearing in slide block 7 downsides by the pad 12 that resets.Drift 4 is positioned at jumper bar 3 downsides, and drift 4 lower ends pass the downside of fixed cover 14 lower ends and slide block 7.Be provided with the adjustment packing ring 21 that is used to regulate the diel closed height between rolling wheel support 16 and the roller support 18; Also be provided with the adjustment pad 22 that is used to regulate drift 4 basal surface positions between jumper bar 3 and the drift 4.
The cushion blocking 11 and the pad 12 that resets all adopt the elastomeric material that can be compressed distortion when bearing pressure, can play cushioning effect to descending jumper bar 3, and can reduce the descending noise of jumper bar 3.Adjust packing ring 21 different-thickness in order to adapt to, brace 17 upper ends are provided with a vertical long kidney-shaped hole 171.
When bent axle 1 rotates towards the bottom dead centre direction, the cam 5 of bent axle 1 both sides forwards bottom dead centre to prior to bent axle 1, by being positioned at the cam 5 of slide block 7 both sides, rolling wheel support 16, it is descending that roller support 18 promotes slide block 7, push down the sheet edge that is stretched by drawing die, because the cam 5 that forwards bottom dead centre to has the outer rim of one section iso-curvature radius, play pressurize effect to the sheet material that is stretched, bent axle 1 drivening rod 2, jumper bar 3 compression cushion blockings 11 promote drift 4 and continue to go downwards to bent axle 1 bottom dead centre, this moment, cam 5 still remained on bottom dead centre continuation flanging, and the downside that drift 4 stretches out slide block 7 promotes the stretching that drawing die is finished sheet material.In drawing process, slide block 7 is pushed down the sheet edge that is stretched all the time by drawing die, so the tensioning member edge can be not wrinkling, and sheet material can not pulled open.Bent axle 1 turns over when after bottom dead center up, and it is up that the nut 25 that is threaded with jumper bar 3 lower ends drives slide blocks 7 by the pad 12 that resets, and cushion blocking 11 restores to the original state, and finishes a working cycles.
In order to reduce slide block 7 impact when descending, be provided with a compensating cylinder 23 between fuselage 20 and slide block 7 as shown in Figure 2, compensating cylinder 23 tops are suspended on the fuselage 20, and compensating cylinder 23 telescopic piston rod heads are fixedlyed connected with slide block 7 upsides by contiguous block 26.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
