Abstract
The invention relates to a cylinder and punch connection structure of a pneumatic press, which is characterized in that the diameter of the top end of a cylinder piston rod is less than that of the back end of the cylinder piston rod, and the top end of the piston rod is provided with an external thread; a connecting plate is a flat metal block; the connecting plate is provided with two bolt mounting holes and a guide hole as well as fixed to the top ends of support plates at the two sides of the punch through two bolts which penetrate through the bolt mounting holes; the guide hole extends out of the two sides of the support plates; the top end of the cylinder piston rod penetrates through the guide hole; and the external thread at the top end of the piston rod is matched with a nut. In the invention, the diameter of the top end of the piston rod is reduced to form a thin and long part which is matched with the guide hole; when the stroke of the punch exceeds downwards, because the connecting plate is thinner, the connecting plate can deform to buffer, so that the punch or the cylinder can not be damaged; and when the stroke of the punch exceeds upwards, because the top end of the piston rod is thin, the top end of the piston rod can slide up and down in the guide hole, thereby ensuring safe operation of the punch and the cylinder.
Description
Technical field
The present invention relates to a kind of punch press, the cylinder and the syndeton between drift that specifically relate on a kind of Pneumatic press are improved, and belong to the punch press technical field.
Background technology
In machining or other field, punch press is a very important production equipment.Pneumatic press mainly drives the drift lifting by the motion of cylinder, then impacts downwards, completes the processing of parts.At present being connected by contiguous block between the cylinder of punch press and drift realizes, as shown in Figure 1, Fig. 1 is the cylinder of punch press of the prior art and the syndeton sketch of drift to structure.Cylinder is positioned at the both sides of drift 2 upper ends, the top of cylinder piston rod 1 is provided with I-shaped connector, contiguous block 3 is fixed on the upper end of the gripper shoe 4 of drift 2 both sides, be milled with T-slot on contiguous block 3, the opening upwards of T-slot, the I-shaped connector on the top of cylinder piston rod 1 inserts in the T-slot of contiguous block 3.By the stretching motion of cylinder piston rod 1, drive contiguous block 3 and upwards lifting of drift 2, drift impacts downwards, thereby completes the punching press action.
Current this syndeton, when for a certain reason, when the position that drift 2 moves downward exceeds the stroke of cylinder piston rod 1, can cause cylinder piston rod 1 to break or cause contiguous block 3 to give birth to and pull out from drift 2, cause the syndeton of drift upside to damage, thereby drift can't be repaired; When the position that drift moves upward exceeds the stroke of cylinder piston rod 1, drift can, by cylinder jack-up, also can cause the damage of cylinder.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of new cylinder and the syndeton between drift, while preventing position limit that drift moves up and down, drift or cylinder are caused to damage.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of cylinder of Pneumatic press and drift syndeton, is characterized in that the diameter on the top of cylinder piston rod is less than the diameter of rear end, is provided with external screw thread on the top of piston rod; Connecting plate is the flat metal derby, be provided with two bolt mounting holes and a pilot hole on connecting plate, connecting plate is by two tops through the gripper shoe that is bolted to the drift both sides of bolt mounting holes, pilot hole stretches out the both sides of gripper shoe, the top of cylinder piston rod is through pilot hole, attaching nut on the external screw thread on piston rod top.
The cylinder of aforesaid Pneumatic press and drift syndeton, is characterized in that the side that described connecting plate is provided with bolt mounting holes is rectangle, is provided with a side of pilot hole for semicircle.
The invention has the beneficial effects as follows: the present invention, by the reduced on the top of piston rod, forms an elongated portion, with pilot hole, coordinates, when punch stroke exceeds, because connecting plate is thinner, only can make connecting plate deform downwards, cushioned, can not be caused the damage of drift or cylinder; When punch stroke upwards exceeds, because the top of piston rod is thinner, can in pilot hole, slide up and down, thereby guarantee the safe handling of drift and cylinder.
The accompanying drawing explanation
Fig. 1 is the cylinder of punch press of the prior art and the syndeton sketch of drift;
Fig. 2 is the cylinder of the Pneumatic press in the present invention and the syndeton sketch of drift;
Fig. 3 is the top view of the connecting plate in Fig. 2.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is done to specific description and description.
Fig. 2 is the cylinder of the Pneumatic press in the present invention and the syndeton sketch of drift; Fig. 3 is the top view of the connecting plate in Fig. 2.
As shown in the figure, the cylinder of Pneumatic press of the present invention and drift syndeton, be arranged to the diameter on the top of the piston rod of cylinder 5 to be less than the diameter of rear end, on the top of piston rod 5, is provided with external screw thread.Connecting plate 6 is the flat metal derby, be provided with two bolt mounting holes 9 and a pilot hole 8 on connecting plate 6, connecting plate 6 is by two tops through the gripper shoe 4 that is bolted to drift 2 both sides of bolt mounting holes 9, pilot hole 8 stretches out the both sides of gripper shoe 4, the top of piston rod 5 is through pilot hole 8, and on the external screw thread on piston rod 5 tops, attaching nut 7.
For ease of distortion and the installation of connecting plate 6, the side that connecting plate 6 is provided with bolt mounting holes 9 is rectangle, is provided with a side of pilot hole 8 for semicircle.
The present invention, by the reduced on the top of piston rod 5, forms an elongated portion, with pilot hole 8, coordinates, and can in pilot hole 8, slide up and down.When drift 2 strokes exceed downwards, because connecting plate 6 is thinner, only can make connecting plate 6 deform, cushioned, can not cause the damage of drift 2 or cylinder.
When drift 2 strokes upwards exceed, because the top of piston rod 5 is thinner, can in pilot hole 8, slide up and down, thereby guarantee the safe handling of drift 2 and cylinder, reduced maintenance and cost of upkeep.
Above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
