Abstract
The utility model discloses an eccentric crank shaft for a punching machine. The eccentric crank shaft comprises an eccentric section and support shafts arranged on the two sides of the eccentric section, wherein the eccentric section comprises three eccentric shafts and connecting blocks arranged on the two sides of each eccentric shaft, and an axial line of the eccentric shaft is parallel to an axial line of each support shaft. The eccentric crank shaft is connected with a sliding block through three connecting rods, and therefore the strength of the block is enhanced, and deformation in the punching process is not easy to occur.
Description
Technical field
The utility model relates to a kind of punch press, is specifically related to the eccentric crankshaft that a kind of punch press is used.
Background technique
The eccentric crankshaft that existing punch press is used comprises 1 eccentric shaft, be arranged on the contiguous block of these eccentric shaft both sides, and the supporting axle that is separately positioned on the contiguous block outside, this eccentric shaft is connected with slide block on the punch press by connecting rod, this structure only adopts a connecting rod to be connected with slide block, so that the intensity of slide block a little less than, easily be out of shape during punching press.
The model utility content
The technical problem that (one) will solve
It is strong that the technical problems to be solved in the utility model provides a kind of intensity of slide block that makes, the eccentric crankshaft that the punch press that is difficult for deforming is used.
(2) technological scheme
For solving the problems of the technologies described above, the eccentric crankshaft that the utility model provides a kind of punch press to use, the supporting axle that it comprises eccentric segment and is arranged on the eccentric segment both sides, eccentric segment comprises 3 eccentric shafts and is arranged on the contiguous block of every eccentric shaft both sides, and the axis of eccentric shaft is parallel with the axis of supporting axle and do not overlap.
Wherein, the equal one in the both sides of every eccentric shaft is provided with step, and the diameter of step is greater than the diameter of this eccentric shaft.
(3) beneficial effect
Compared with prior art, the utility model will be connected with slide block by 3 connecting rods, make the intensity enhancing of slide block, be difficult for deforming in stamping process.
Description of drawings
Fig. 1 is the structural representation of the eccentric crankshaft used of the utility model punch press.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but can not be used for limiting scope of the present utility model.
As shown in Figure 1, the eccentric crankshaft that this punch press is used comprises eccentric segment and is arranged on the supporting axle 2 of eccentric segment both sides, this eccentric segment comprises 3 eccentric shafts 11 and is arranged on the contiguous block 12 of every eccentric shaft 11 both sides, and the axis of eccentric shaft 11 is parallel with the axis of supporting axle 2 and do not overlap.
The equal one in the both sides of every eccentric shaft 11 is provided with step 111, and the diameter of step is greater than the diameter of this eccentric shaft 11, this step 111 be provided for spacing to connecting rod.
The utility model will be connected with slide block by 3 connecting rods, make the intensity enhancing of slide block, be difficult for deforming in stamping process.
It below only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
