Detailed Description

The present invention will be further described with reference to specific embodiments for the purpose of facilitating an understanding of technical means, characteristics of creation, objectives and functions realized by the present invention, but the following embodiments are only preferred embodiments of the present invention, and are not intended to be exhaustive. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents and the like used in the following examples are commercially available unless otherwise specified.

Example (b):

as shown in fig. 1-3, a pneumatic limiting mechanism of a stamping die comprises a die base 1 and a pressing plate 2, wherein a pressing groove opening 3 is formed in the die base 1, a limiting mechanism 4 is arranged in the die base 1 in a penetrating manner, the limiting mechanism 4 comprises an air pipe 42 arranged in the die base 1 in a penetrating manner, an input end of the air pipe 42 is communicated with an air pump 41, an output end of the air pipe 42 is communicated with a sliding seat 43, the sliding seat 43 is welded on the top surface of the die base 1 in a mirror image manner, and the inner wall of the sliding seat 43 is connected with a limiting slide block 44 in a sliding manner;

the working principle is as follows: the staff at first places the punching press material level that needs directly over indent mouth 3 that the inside of die holder 1 was seted up, as shown in fig. 3, drive the inside air pump 41 of stop gear 4 afterwards, make inside the air pipe 42 that air pump 41 inputs its output intercommunication with high-pressure draught, because air pipe 42 output intercommunication slide 43, make the inside a large amount of high-pressure draught of dashing into of slide 43, finally promote the spacing slider 44 outwards slip rather than inner wall sliding connection, as shown in fig. 2, mirror image distribution will need punching press material to carry out spacing centre gripping fixed until spacing slider 44, the effectual impact force of having avoided the production of current device is easily with material skew primary importance, be favorable to carrying out spacing fixed with device punching press material, the accurate nature of device punching press has been improved.

As shown in fig. 2 and 4, fixing parts 5 are welded around the top surface of the die holder 1, each fixing part 5 includes a support rod 51 welded with the die holder 1, a threaded rod 52 is welded at the top end of the support rod 51, a sleeve rod 53 is connected to one end of the threaded rod 52 far away from the support rod 51 through threads, and through holes 6 are formed inside the periphery of the press plate 2; specifically, the method comprises the following steps: the diameter of the through hole 6 is larger than that of the threaded rod 52, and the threaded rod 52 can penetrate through the through hole 6; the staff is at first with loop bar 53 screw upwards rotatory break away from threaded rod 52, penetrate threaded rod 52 with clamp plate 2 through-hole 6 that inside all seted up all around afterwards to make clamp plate 2 follow the removal and need the punching press material top surface until 2 bottom surfaces laminating of clamp plate, wear out 6 one ends of through-hole with loop bar 53 screw in threaded rod 52 again, effectually avoided current device can't fix mould seat 1 and clamp plate 2, be favorable to fixing the inside mould seat 1 of device and clamp plate 2, increased the practicality of device.
