Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a steel plate punching die convenient for accurate positioning comprises an upper die base 1, a mounting plate 2, a positioning column 3, a fixing plate 4, a through groove 5, a punch 6, a positioning groove 7, a damping pad 8, a damping spring 9, a lower die base 10, a base 11, a placing plate 12, a pressing plate 13, an elastic spring 14, a containing groove 15, a baffle 16 and a fixing hole 17, wherein the mounting plate 2 is fixed at the bottom of the upper die base 1, the positioning column 3 is arranged at the bottom of the mounting plate 2, the fixing plate 4 is arranged on the inner side of the mounting plate 2, the through groove 5 is formed in the fixing plate 4, the punch 6 is arranged right below the upper die base 1, the bottom of the positioning column 3 is connected with the lower die base 10 through the positioning groove 7, the damping pad 8 and the damping spring 9 are arranged in the positioning groove 7, the base 11 is arranged at the bottom of the lower die base 10, the placing plate 12 is arranged right above the lower die, the pressing plate 13 is connected with the inner wall of the placing plate 12 through an elastic spring 14, a containing groove 15 is formed in the placing plate 12, a baffle plate 16 is installed at the top of the containing groove 15, and a fixing hole 17 is formed in the middle of the baffle plate 16;

the positioning columns 3 and the mounting plates 2 are of an integrated structure, 2 groups of the mounting plates 2 and the positioning columns 3 are arranged, and 2

positioning columns

3 and 2 mounting plates 2 in each group are arranged, so that the connection between the upper die base 1 and the lower die base 10 can be more accurate, and the normal operation of punching a steel plate is ensured;

the bottom of the fixed plate 4 and the bottom of the punch 6 are positioned on the same straight line, and the depth of the through groove 5 in the fixed plate 4 is greater than half of the height of the pressing plate 13, so that when the punch 6 punches the steel plate, the pressing plate 13 can enter the through groove 5 in the fixed plate 4, and the work of the punch 6 is not affected;

the damping pad 8 and the positioning groove 7 are connected in a bonding mode, and the size of the positioning groove 7 is matched with that of the positioning column 3, so that the vibration force of the whole mold can be effectively reduced when the mold is positioned, and the stability of the mold in use is further ensured;

the number of the pressing plates 13 is two, 2 pressing plates 13 form a telescopic structure in the placing plate 12 through elastic springs 14, the bottom of each pressing plate 13 is in sliding connection with the inner wall of the placing plate 12, the front side of the steel plate can be limited, and the steel plate is effectively prevented from shifting;

baffle 16 and the connected mode of placing board 12 are the block connection, and the diameter of the inside fixed orifices 17 of baffle 16 is greater than the diameter of drift 6, and the waste material that produces when being convenient for make the steel sheet punch falls into from fixed orifices 17 and accomodates groove 15, easily the later stage is to the concentrated clearance of waste material.

The working principle is as follows: when the steel plate punching die convenient for accurate positioning is used, as shown in fig. 1 and 3, firstly, a worker places a base 11 and a lower die holder 10 at corresponding positions, then pulls pressing plates 13 at two sides outwards simultaneously, so that the bottoms of the pressing plates 13 slide along the inner walls of a placing plate 12, an elastic spring 14 is extruded, the distance between the 2 pressing plates 13 is increased, then a steel plate to be punched is placed between the 2 pressing plates 13, the pressing plates 13 are loosened, the pressing plates 13 return under the reset action of the elastic spring 14, the front side of the steel plate is limited, the phenomenon of displacement of the steel plate is prevented, then the worker descends the upper die holder 1, so that a mounting plate 2, a positioning column 3, a fixing plate 4 and a punch 6 at the bottom of the upper die holder 1 descend simultaneously, and because the lowest end of the positioning column 3 is lower than the lowest end of the punch 6, the positioning column 3 can enter a positioning groove 7, the damping cushion 8 and the damping spring 9 are arranged inside the positioning groove 7, so that when the positioning column 3 descends, the vibration force to the lower die holder 10 can be relieved through the damping cushion 8 and the damping spring 9, and meanwhile, the connection between the upper die holder 1 and the lower die holder 10 can be ensured to be faster and more accurate;

as shown in fig. 4, since the through groove 5 is formed inside the fixing plate 4, and the bottom of the fixing plate 4 and the bottom of the punch 6 are aligned, when the punch 6 contacts the steel plate, the pressing plate 13 enters the through groove 5, therefore, the processing of the steel plate is not influenced, as shown in figure 2, because the baffle 16 is internally provided with a fixing hole 17, and the central axis of the fixing hole 17 and the central axis of the punch 6 are on the same straight line, so when punching a steel plate, the positioning of the punch 6 can be more accurately performed, and the scraps generated during the punching can fall from the fixing hole 17 into the receiving groove 15, the waste materials are collected in a centralized way, thereby not only reducing the influence on the surrounding working environment, but also bringing convenience for cleaning the later-stage workers, improving the practicability of the die, the above is the operation of the whole device, and the details not described in the present specification are the prior art known to those skilled in the art.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
