Special tool for replacing numerical control punching die

Technical Field

The utility model belongs to the mechanical engineering field especially relates to a specialized tool for changing numerical control punching die.

Background

The numerical control punching machine is mainly used for finishing the machining of holes in the longitudinal beam for production equipment for producing the longitudinal beam of the heavy truck frame. In the process of long-term production operation, because the clearance between the lower die holder and the female die of the die is very small, the outer edge end of the female die is flush with the outer edge end of the die holder, and a processing person can not take the next hand when replacing the quick-wear part (female die) for a plurality of times. The current method is as follows: the concave die is replaced in a squeezing and smashing mode by combining the crowbar, the inner hexagonal wrench and the sharp corner of the leftover material, time and labor are wasted during replacement every time, and potential safety hazards exist. Particularly, when the inner side female die is taken out, the outer side female die is taken out by a crow bar, and then the inner side female die is pried out by the same method. The method is very inconvenient, wastes time and labor, causes low production efficiency and increases processing time. Therefore, a special tool for replacing the numerical control punching concave die is urgently needed, so that the replacement of the numerical control punching concave die is conveniently and effectively completed by workers, and the production efficiency is improved.

SUMMERY OF THE UTILITY MODEL

The utility model provides a specialized tool for changing numerical control punching die, dismouting method is simple, can make things convenient for the staff to accomplish the change that numerical control punched the die to its work efficiency has been promoted.

In order to solve the problems in the background art, the utility model discloses a realize through following technical scheme:

a special tool for replacing a numerical control punching and concave die comprises a screw, a nut, a spring, an inclination baffle, a tension cover plate, a support column and a pin shaft;

one end of the screw rod is connected with the inclination baffle through the pin shaft, the other end of the screw rod penetrates through the tension cover plate, a nut is arranged at one end, extending out of the tension cover plate, of the screw rod, the spring is sleeved on the screw rod and located between the inclination baffle and the tension cover plate, and the support columns are arranged on two sides, located on the bolts, of the tension cover plate.

As a further explanation of the utility model: the top of the screw rod is provided with a chute.

As a further explanation of the utility model: and two flat surfaces are arranged on one half thread of the screw rod.

As a further explanation of the utility model: the two ends of the bolt are respectively positioned in the centers of the inclination baffle and the tension cover plate.

Compared with the prior art, the utility model discloses following profitable technological effect has:

1. by applying the tool in a production field, the average time for replacing the female die by adopting an invasive front method is about 30 minutes actually, and the average time for replacing the female die by adopting the special tool is about 6 minutes; the precision of the inner hole of the lower die holder is not damaged, and the tooling has strong universality. The time saved by replacing the female die every 1 time can be saved by producing 2 longitudinal beams, the production efficiency of the tool is greatly improved, and workers are assisted to quickly and effectively complete the work of replacing the numerical control punching and female die.

2. The chute at the top of the screw can ensure that the inclination baffle has certain degree of freedom during working.

3. Two flat surfaces are arranged on a half thread of the screw rod, so that the tool is matched with the long round hole in the cover plate when in use, the screw rod does not rotate and only can rise when the nut is fastened, the upper plane of the cover plate is a stress surface, and the female die can be separated from the lower die holder after the nut rotates.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the product of the present invention is used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
