Abstract
The utility model relates to a special-shaped terrace die structure. The special-shaped terrace die structure comprises a terrace die and a pin shaft installed in a center hole of the terrace die, wherein a spring is installed at the left end of the pin shaft; a thread is arranged at the right end of the pin shaft; a threaded sleeve is screwed into the center hole of the terrace die; the pin shaft penetrates through the threaded sleeve and extends out of the terrace die; a thread is arranged at the tail of the pin shaft; the tail of the pin shaft is locked through two locking nuts; a fixing ring is connected to the front end of the pin shaft in a sleeved mode; the fixing ring and the pin shaft are connected through a thread pair; a plurality of through holes are formed in the outer surface of the pin shaft. The terrace die structure can uncover punching waste materials, the pressure of the spring is adjusted according to requirements, and the fixing ring can adjust the pressure of the spring and can also play a role in guiding the pin shaft at the same time.
Description
Technical field
The utility model relates to mould applications, relates in particular to a kind of special-shaped punch structure.
Background technology
Cold punching technology is a kind of cutting highly efficient in productivity, few or without the advanced processing method of cutting, in economy and technical elements, all has advantages of a lot.It is easy and simple to handle, is convenient to realize mechanization and automation, is suitable for the production of part more in enormous quantities, and its goods generally do not need to do further machining, and dimensional accuracy and interchangeability are also all relatively good.So it occupies very consequence in the industry such as aviation, automobile, tractor, electrical equipment and electrical, precision instrumentation.In the middle of punching production, diel, as the concrete executing means of Sheet Metal Forming Technology, enjoys attention naturally, and in fact, the design level of punching die structure and the accuracy of manufacture are the keys that guarantees stamped part quality.Under some special punching press operating mode, need to use the punch structure of some polymorphic structures, be convenient to take off from punched scrap.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of special-shaped punch structure.
The utility model is to be achieved through the following technical solutions:
A kind of special-shaped punch structure, comprise punch, be arranged on the bearing pin in punch centre bore, on the left end of described bearing pin, spring is housed, right-hand member is threaded, and in the centre bore of punch, screws in and has thread bush, and described bearing pin is through thread bush and stretch out punch, afterbody at bearing pin is provided with screw thread, and with the locking of two locking nuts, at the front end sleeve of bearing pin, being connected to retainer ring, the outer surface of described bearing pin also offers several through holes.
As optimal technical scheme of the present utility model, described retainer ring adopts screw thread pair to be connected with bearing pin.
As optimal technical scheme of the present utility model, the quantity of described thread bush is two.
As optimal technical scheme of the present utility model, the coefficient of elasticity of described spring is 100Nm.
Compared with prior art, the beneficial effects of the utility model are: the punch structure that the utility model provides can be taken off from punched scrap, the pressure of spring regulates as required, and the pressure-acting that retainer ring can regulating spring can play the guiding role to bearing pin again simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-punch; 2-bearing pin; 3-spring; 4-thread bush; 5-locking nut; 6-retainer ring; 7-through hole.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of special-shaped punch structure, comprises punch 1, is arranged on the bearing pin 2 in punch 1 centre bore, and spring 3 is housed on the left end of described bearing pin 2, and the coefficient of elasticity of described spring 3 is 100Nm.Right-hand member is threaded, and screws in that to have thread bush 4, the quantity of described thread bush 4 be two in the centre bore of punch 1.Described bearing pin 2 is through thread bush 4 and stretch out punch 1, afterbody at bearing pin 2 is provided with screw thread, and with two locking nuts 5 locking, at the front end sleeve of bearing pin 2, is connected to retainer ring 6, described retainer ring 6 adopts screw thread pair to be connected with bearing pin 2, and the outer surface of described bearing pin 2 also offers several through holes 7.
The punch structure that the utility model provides can be taken off from punched scrap, through-hole structure is made by the central authorities of punch 1, the right end portion of through hole is threaded, screwed in two thread bush 4, be adjusted to behind suitable position, bearing pin has been passed to spring, again together from left to right through thread bush 4, the pressure of spring regulates as required, and the pressure-acting that retainer ring 6 can regulating spring 3 can play the guiding role to bearing pin 2 again simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
