Abstract
The invention discloses a multifunctional terrace die which comprises a terrace die body. An elastic guide nail stretching out of the head of the terrace die body is arranged on the terrace die body, and air injection holes communicated with an external air compressing device through air channels are formed in the head. According to the designed terrace die, besides the basic blanking function, the elastic guide nail is added, and therefore during guide, the size precision of a strip is guaranteed, and a product cannot bounce up and down. The air injection holes in the terrace die are used for material return, waste can fall stably and does not move together with the terrace die, stability is improved, and the blanking quality and precision and safe reliability are guaranteed. In addition, blanking chips are made to fall off the die in time through high-pressure air, and the influence of the blanking chips on the quality of the strip is reduced.
Description
Technical field
The invention belongs to mould, it is specifically related to a kind of multi-functional punch.
Background technology
Owing to high-accuracy nuclear power and fuel beam thickness are thinner, material width is shorter, width is irregular descends bending more in shape, middle shaping form is complicated, length direction bending is more difficult, the ununiformity of material thickness just highlights, and causes unstable during mould punching product, affects the use properties of nuclear power nuclear fuel band. Therefore nuclear power nuclear fuel band mould manufactured and designed precision, planeness, internal diameter and cylindrical with axle degree and gouged spews have extremely high requirement.
China is not also very ripe in nuclear power band Making mold, and existing punch generally has stamping-out and correcting effect, but often has adhesion effect for the waste material after stamping-out, occurs to jump material phenomenon, affects stamping-out effect and the work-ing life of mould. The punch of some punch such as band top material, can prevent scrap rising, but it is lower to play correcting effect precision, in addition it is also necessary to installs top material pin, can not well process for waste material chip. So we are in order to obtain the higher band of precision, it is necessary to development function is more complete, and the punch that precision is higher realizes correcting, stamping-out, and the material returned carries out simultaneously. This is the big difficult problem of China's mold manufacturing industry one.
Summary of the invention
It is an object of the invention to the defect for prior art, it is provided that a kind of punching precision height, the multi-functional punch jumping material and band material can be prevented.
The technical scheme realizing the object of the invention employing is as follows:
Multi-functional punch provided by the invention, comprises punch body, and described punch body is provided with the elasticity correcting nail stretching out punch body head, and described head is provided with the gas orifice being compressed device and being connected by air flue and external air.
Described gas orifice is by the three of triangular arrangement.
Useful effect
The punch of inventive design, except basic stamping-out effect, has also added elasticity correcting nail, ensure that the dimensional precision of band when correcting, product can be made not beat up and down. Gas orifice on punch is used for the material returned, owing to gas orifice is in plane triangulation structure, can make waste material uniform force, steady fall, not move together with punch, enhanced stability, ensures stamping-out Mass accuracy and safe reliability. And high pressure gas make stamping-out chip drop from mould in time, reduce it to the impact of band quality. The present invention, by comprehensive on same punch for these three kinds effects, can ensure band quality.
The technical scheme of the present invention is described further below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the mould structure schematic diagram of application the present invention.
Fig. 2 is mold use view.
Fig. 3 is the structural representation of punch of the present invention.
Fig. 4 is the vertical view of punch of the present invention.
Embodiment
It is the mould of application the present invention shown in Fig. 1, it is made up of upper backing plate 1, punch retainer 2, discharging plate seat 3, punch 4, lower die holder 5, upper die holder 6, punch pressing plate 7, discharging plate 8, material strip 9 and die version 10. During assembling mould, with pressing plate 7, punch 4 is fixed on punch retainer 2, by intact for the assembling of other parts of mould. The multi-functional punch of the present invention is as shown in Figure 3, Figure 4, comprise punch body 406, described punch body 406 is provided with the elasticity correcting nail stretching out punch body 406 head, the spring 404 that elasticity correcting nail comprises correcting nail 401, the screw 403 that is located in threaded hole 402 and is located between screw 403 and correcting nail 401, the head of punch body 406 is provided with the gas orifice 407 being compressed device and being connected by air flue 405 and external air, and gas orifice 407 is by three of triangular arrangement.
As shown in Figure 1, punch 4 is before stamping-out, and correcting nail 401 enters material strip correcting nail prior to punch 4, and material strip 9 is implemented correcting, accurately location material strip 9. Due to various factors in stamping-out process, very strong magnetism is had between waste material and punch 4, for preventing waste material from lifting together with punch 4, leading to the air pressure into certain pressure intensity in gas groove 5, three pores present trilateral state, present a plane, when punch 4 moves to Fig. 2 position, under the effect of uniform air-flow surging force, rush material waste material and dropped to waste material groove by impact, owing to waste material is hit power evenly, reverse when preventing waste material from falling. Stamping-out process is carried out smoothly. After stamping-out terminates, mould returns to starting position.
Claims (2)
1. a multi-functional punch, comprises punch body, it is characterized in that described punch body is provided with the elasticity correcting nail stretching out punch body head, and described head is provided with the gas orifice being compressed device and being connected by air flue and external air.
2. multi-functional punch according to claim 1, is characterized in that described gas orifice is by the three of triangular arrangement.
