Description

Automotive interior spare cut-out press convenient to change drift

Technical Field

The utility model relates to a cut-out press technical field especially relates to an automotive interior spare cut-out press convenient to change drift.

Background

The punching process is a metal processing method, which is based on the plastic deformation of metal, and utilizes a die and punching equipment to apply pressure to a plate so as to enable the plate to generate plastic deformation or separation, thereby obtaining a part with certain shape, size and performance; the punching forming process plays an important role in the manufacturing process of the automobile body, and particularly, large covering parts of the automobile body are mostly complicated in shape, large in structural size, and high in surface quality requirement because of the fact that some covering parts are also curved surfaces, so that the parts can not be manufactured by other processing methods by using the punching processing method; almost all of a cab, a front sheet metal part, a cargo compartment plate of a heavy-duty truck, various car body covering parts of a car, various frameworks of a passenger car and the like are manufactured by a punching processing method, so that in the processing process, a punching die for automobile interior parts is widely applied by people; the prior punching die punches the interior part by controlling a punch through a hydraulic device;

according to the design, the dies can only be integrally replaced when worn or damaged in the using process of the dies, the dies are high in manufacturing cost, the integral replacement is very inconvenient, and once damaged, the cost generated during replacement is very high, unnecessary economic loss is caused, the labor cost and the equipment cost are increased;

through retrieval, the punch replacing structure of the punching die machine disclosed by the application number CN201920286812.5 avoids the loosening phenomenon through the design of the thread structure between the upper base pillar and the punch, and further limits the position and the rolling of the punch through the action of the fixing device consisting of the inserted link and the spring, and in the process of replacing the punch, the punch is withdrawn along the gap of the internal thread structure by rotating the punch, so that the replacing operation is very convenient, and the problems that the punch can only be integrally replaced when the die is worn or damaged in the using process of the die, is very inconvenient, and once the punch is damaged, the cost generated in the replacing process is very high, and unnecessary economic loss is caused are effectively solved;

with respect to the above patents, the following drawbacks remain: in the patent, though can realize the change of drift through setting up fixing device and helicitic texture, when the drift that treats the change needs to be installed, at first twist the drift to the foundation column through helicitic texture soon, it is effective spacing to realize foundation column and drift through fixing device, the installation of drift is fixed to have been realized, however, the in-process of change, need twist the screw thread repeatedly, this operation process is not only loaded down with trivial details, consuming time power, it is long when having prolonged the change of drift, the change progress has been dragged slowly, make it be not convenient for change, change inefficiency, and the phenomenon of wearing and tearing appears in the screw thread easily, cause foundation column and drift installation unstability, make the drift can take place to rock in the punching press process, the steadiness of drift installation has been reduced, and then make the quality of punching a hole of interior trim part cause certain influence, the probability that the wastrel appears has been increased.
