Description

The wheel rim automatic punch machine structure of improvement

Technical field

The utility model is a kind of wheel rim automatic punch machine structure of improvement, refer in particular to the wheel rim that is applicable to various different pitch-rows and size, and it is that punching post with corresponding wheel rim hole count carries out the punching action synchronously, thereby the accurate quality-improving of punching, its mould finishes in the punching of punching post and can locate motionlessly when retreating again, thereby can not cause the clamping situation.

Background technology

Present traditional wheel rim automatic punch machine, as Fig. 6-shown in Figure 8, it mainly is that a disc substrate 102 is set on the pedestal 101 of a hollow circular tube shape, these substrate 102 central authorities are provided with a chip-removal hole 103, the one strip fixed strip 104 by chip-removal hole 103 centers of circle is set on the chip-removal hole 103, fixed strip 104 central authorities set firmly a fixed leg 105 vertically upward with respect to substrate 101 home positions, set firmly the positioning disk 106 of tool particular circle footpath size on the fixed leg 105, on the substrate 102 array fixing threaded hole 107 is set radially in addition, and on the fixing threaded hole 107 of particular group, set firmly a railroad shoe 108, but the slide 109 that a relative orbit seat 108 slides is set on the railroad shoe 108, set firmly an oil pressure punching seat 110 on the slide 109, the end face of oil pressure punching seat 110 is arranged with and forms a Qian shape opening 111, in addition being provided with one in oil pressure punching seat 110 towards an end of substrate 102 peripheries runs through oil pressure punching seat 110 and wears axis hole 112 to opening 111, and form in oil pressure punching seat 110 and to be installed with oil compression rod 114 on the relative external end edge of wearing axis hole 112 and to run through the oil hydraulic cylinder 113 of wearing axis hole 112 and slightly stretching into opening 111, and this oil hydraulic cylinder 113 with wear axis hole 112 and be interconnected, and be provided with a punching die 115 in oil compression rod 114 free ends of oil hydraulic cylinder 113, be provided with one with to wear axis hole 112 coaxial relative and run through the ccontaining open-work 116 of oil pressure punching seat 110 in the in addition end of oil pressure punching seat 110 again towards substrate 102 centers of circle, be arranged with punching sleeve pipe 117 in ccontaining open-work 116 towards an end of opening, be provided with one simultaneously with ccontaining open-work 116 and wear axis hole 112 coaxial relative chip removal open-works 118 in punching sleeve pipe 117, moreover in oil pressure punching seat 110 be provided with that an end is fixed on the oil pressure punching seat 110 and in addition end towards the spring 119 in substrate 102 centers of circle, and on the spring 119 of each oil pressure punching seat 110, collude the centring ring 120 of establishing the specific size of a tool jointly, on oil hydraulic cylinder 113, be connected with one in addition and go into oil pipe 121, and on oil pressure punching seat 110, be connected with one and penetrate into the oil return pipe 122 of axis hole 112, and respectively go into oil pipe 121 and oil return pipe 122 is connected to oil pressure group Pu 123.Its major defect is:

One, after punching finishes, when oil compression rod 114 retreats,, and there is not any resistance power because of 110 of oil pressure punching seats are subjected to spring 119 unidirectional drawing gravitations, so oil compression rod 114 retreats and easily causes the clamping situation, and make wheel rim 124 distortion or split by seam crossing;

Two, its each oil hydraulic cylinder 113 responsivenesses differ, so the punching sleeve pipe 117 that is sheathed on the oil pressure punching seat 110 relatively can't be simultaneously against wheel rim 124, thereby easily causes the skew of wheel rim 124 central points, and each pitch-row of wheel rim 124 are differed;

Three, during the wheel rim 124 of its desire processing different size, need change suitable positioning disk 106 thereupon, thereby cause the inconvenience in the use, and need to prepare many group positioning disks 106 and cause and take up room and cost increases.

The inventor is because the disappearance of above-mentioned traditional wheel rim automatic punch machine, satisfies with for many years experience and designed, and through inquiring into and study sampling test in many ways, and repeatedly revises improvement, creates the technical solution of the utility model.
