Abstract
The utility model provides a quick stamping cylinder with an embedded guide rotation-proof device. The cylinder comprises a cylinder bottom, a cylinder assembly and a small cylinder arranged in the front, wherein a piston rod is arranged in a cylinder, a guide sleeve of which the edge is matched with the cylinder is sleeved at the front end of the piston rod, the piston rod and the guide sleeve are fixedly connected to achieve the sliding guide of the piston rod in a stamping process, a mandrel is embedded in the piston rod, an end cover which is fixedly connected to the piston rod is arranged at the rear end of the mandrel in a fit mode, a connecting hole and a key slot are arranged in the front of the mandrel, a clamping key is arranged in the key slot, and the clamping key is fixed to the mandrel through a screw and the connecting hole. By the aid of the structure, the force is exerted on the stamping cylinder stably, the abrasion is uniform and the installation is quick and convenient.
Description
Technical field
The utility model relates to the punching equipment technical field, is specifically related to a kind of quick punching cylinder of built-in guiding anti-rotation device.
Background technique
cylinder structure in the most employing of existing quick punching cylinder cylinder, its structural type is: the built-in cylinder oilhole of punching cylinder piston rod is connected with quick hydraulic fluid port, reduce because built-in cylinder intracavity section is long-pending, under the constant condition of hydraulic system power, under sectional area reduces to realize that the punching cylinder piston rod is fast, built-in cylinder guide sleeve of while coordinates with built-in mandrel realizes leading role, cylinder bottom partially fluid-filled mouth with on put fuel tank and be connected, realize quick topping up, but during the Hydraulic Cylinder operation, piston rod easily produces rotation in descending process, cause the workpiece size precision of processing inadequate, processing effect is undesirable, affect the quality of product.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of quick punching cylinder of built-in guiding anti-rotation device, makes punching cylinder stressed more steady in stamping process, wear and tear more even, and convenience quick for installation.
for achieving the above object, the technical solution adopted in the utility model is: a kind of quick punching cylinder of built-in guiding anti-rotation device, comprise cylinder bottom, cylinder assembly and fore little cylinder is set, be provided with piston rod in cylinder barrel, the piston rod front end sleeve is equipped with the guide sleeve that outer rim coordinates with cylinder barrel, piston rod and guide sleeve are fastenedly connected the slide-and-guide of realizing piston rod in stamping process, piston rod is built-in with mandrel, core back-end's cooperation is provided with the end cap that is fixedly connected with piston rod, described mandrel front portion is provided with attachment hole and keyway, the built-in card key of keyway, card key is fixed on mandrel by screw and attachment hole.
As preferably, described card key adopts flat key, and its kayser anti-rotation is effective.
As preferably, described card key is 25～30mm along the length of mandrel axial direction, can avoid again the stuck of mandrel and piston rod in stamping process when satisfying anti-rotating function.
The beneficial effects of the utility model are according to the narration of such scheme as can be known: the quick punching cylinder of this built-in guiding anti-rotation device, mandrel front portion at traditional punching cylinder is provided with attachment hole and keyway, the built-in card key of keyway, card key is fixed on mandrel by screw and attachment hole, make punching cylinder stressed more steady in stamping process, wear and tear more even, can prevent that effectively in stamping process, piston rod rotates, its rotation prevention structure is simple, convenience quick for installation.
