Description

But fast moving's piercing depth

Technical Field

The specification belongs to the technical field of dies, and particularly relates to punching equipment capable of moving rapidly.

Background

In the prior art, the standard fixing seat is directly and fixedly connected with the die cavity on the upper die holder through the fixing pin. The existing fixing seat is a standard component which can be purchased directly. And the standard component fixing bases purchased directly are triangular prisms. And when the standard component is installed, the die cavities matched with the standard component fixing seats are triangular prisms.

When the upper die holder is directly matched with the standard part fixing seat through the die cavity, the die has the advantages of small appearance, no occupied space and good positioning precision. The disadvantage of this type of construction is that it is inconvenient for the fitter to maintain the direct and quick displacement. In the die debugging stage, some round punches often need to be capable of being directly and rapidly shifted, and when the integral machining matching precision of the die is not up to the requirement, the round punches also need to be directly and rapidly shifted. If the displacement is required, the positioning pin needs to be moved, that is, the large die carrier needs to be repaired, and each displacement needs to be carried out with great resources, cost and time.

In view of the above problems, no effective solution has been proposed at present.

Detailed Description

In order to make the technical solutions in the present specification better understood by those skilled in the art, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only some embodiments of the present specification, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "middle", "lower", "inner", "outer", "front", "rear", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or component to be referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. The terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art. Hereinafter, an embodiment of the present utility model will be described in terms of its overall structure.

Referring to fig. 1, an embodiment of the present application provides a rapidly movable punching apparatus, including:

the upper die holder 100, the upper die holder 100 comprises a die cavity 110, the die cavity 110 is square, and the die cavity 110 comprises a cavity bottom 111 and a cavity wall 112;

the fixing assembly 200, the fixing assembly 200 includes a base plate 210, a spacer 220 and a fixing base 230, the base plate 210 has a first side wall 211 and a second side wall 212 opposite to each other, the first side wall 211 is fixedly connected with the cavity bottom 111 of the cavity 110, the second side wall 212 is fixedly connected with one side of the fixing base 230, and a plurality of spacers 220 are fixedly arranged between the base plate 210 and the cavity wall 112;

the round punch 300, the round punch 300 is fixedly installed at the other side of the fixing base 230.

Referring to fig. 1, 2 and 3, the round punch 300 is fixedly disposed on a fixing base 230 in the fixing assembly 200, the fixing base 230 is disposed on a base plate 210, and the base plate 210 is disposed on a cavity 110 of the upper die holder 100. Specifically, the round punch 300 has a working end for punching and the like and a mounting end fixed in the fixing base 230. The sidewall of the fixing base 230 is mounted on the second sidewall 212 of the pad 210, and preferably, the fixing base 230 is fixedly connected with the pad 210 by a positioning pin. The positioning pins are arranged to enable the connection between the fixing base 230 and the second side wall 212 of the base plate 210 to be more tight. More preferably, as shown in fig. 3, two locating pins are provided adjacent to and at a distance from the two side boundaries of the second side wall 212. The two locating pins are arranged in this way, so that the fixing seat 230 is more tightly connected with the base plate 210, and the shearing force of the locating pins to the fixing seat 230 and the base plate 210 is more uniform, so that the service life of the equipment is greatly prolonged.

The cavity 110 is provided in a square shape. A gap exists between the cavity wall 112 of the square cavity 110 and the backing plate 210. In this gap are mounted shims 220, preferably a plurality of shims 220 are symmetrically disposed between backing plate 210 and chamber wall 112. In a general embodiment, the position of the shim plate 210 is further fixed by filling four shims 220 into the gap existing between the cavity wall 112 of the cavity 110 and the shim plate 210, mainly preventing the shim plate 210 from moving in a horizontal position.

It is understood that in the prior art, the upper die holder 100 is mostly directly fixedly connected to the fixing base 230. In operation by those skilled in the art, the cavity 110 of the upper die holder 100 is configured to mate with the shape of the triangular prism of the anchor block 230. In the inspection process, the round punch 300 needs to be moved to adjust its position. If the round punch 300 is displaced, the positioning pin needs to be removed, and the die carrier also needs to be repaired. This is extremely inconvenient for the worker to perform debugging and inspection, and increases the cost of the apparatus in performing processing.

In this application, the shape of the cavity 110 is set to be the same direction as the pad 210 by adding the pad 210, and the first sidewall 211 of the pad 210 is fixedly connected with the cavity bottom 111 of the cavity 110. A clearance exists between the backing plate 210 and the cavity wall 112 of the cavity 110, and the gasket 220 is disposed in the clearance. Further, the first sidewall 211 of the pad 210 is tightly contacted and fixedly connected with the cavity bottom 111 of the cavity 110, and the first sidewall 211 of the pad 210 is tightly contacted with the cavity bottom 111 of the cavity 110 and the gasket 220. The dimensions of shim 220 may be adjusted as needed by those skilled in the art to adjust the position of round punch 300. Specifically, the pad 220 may be added, or the thickness of the pad 220 may be changed by polishing the pad, or both embodiments may be performed simultaneously. Such adjustment does not require disassembly of the alignment pins of the fixed holder 230 and does not damage the mold frame. Therefore, the structure can not only meet the requirements of the technicians in the field on the quick adjustment of the relative position of the round punch 300, but also avoid the damage caused by the disassembly of parts, and reduce the cost of the die debugging stage.

In summary, by adding the pad 210 and the spacer 220 and changing the shape of the cavity 110, a person skilled in the art can further change the relative position of the pad 210 by changing the setting of the spacer 220, and the change of the relative position of the pad 210 can change the relative position of the round punch 300, so as to realize the rapid movement of the round punch 300.

In the operation of those skilled in the art, it is preferable that the round punch 300 is provided with a stepped portion 310, the fixing base 230 is provided with a stepped hole 231, and the fixing of the round punch 300 is performed by the cooperation of the stepped portion 310 and the stepped hole 231. In another embodiment of the present application, the fixing base 230 is a standard. The standard fixing base 230 has three stepped holes 231 with opposite internal structures, and the three stepped holes 231 are disposed at three corners of the fixing base 230, as shown in fig. 6. The round punch 300 is provided with a working end and a mounting end in another embodiment of the present application, and in this embodiment, the step portion 310 is provided at the mounting end of the round punch 300. The fixing base 230 and the round punch 300 are fixed by the mutual limitation of the shapes of the parts, so that the connection between the parts is firmer. It should be noted that, one side of the fixing base 230 is fixedly connected to the second sidewall 212, so that one side of the step portion 310 of the round punch 300 contacts the second sidewall 212.

Preferably, the corners of the stepped portion 310 and the stepped hole 231 are chamfered. During the repeated punching of round punch 300, repeated forces and reaction forces are received. The step portion 310 and the stepped hole 231 after chamfering can effectively avoid the condition of stress concentration in repeated work, thereby prolonging the service life of the equipment.

Preferably, the depth of the cavity 110 is less than the distance the shim plate 210 extends toward the location of the circular punch. The arrangement is such that the die cavity 110 does not affect the installation of the fixing base 230 due to the upper die holder 100 while the relative position of the base plate 210 is being located. When the depth of the cavity 110 is greater than or equal to the distance that the backing plate 210 extends toward the direction where the round punch is located, a gap exists between the cavity wall 112 of the cavity 110 and the fixing base 230, and if the waste falls into the gap, the fixing base 230 is damaged, so that the installation of the round punch 300 is affected.

More preferably, as can be seen from fig. 1, in the actual sizing of the shim 220, the shim 220 extends toward the location of the round punch 300 by a length greater than the depth of the cavity 110 and less than or equal to the distance the shim plate 210 extends toward the location of the round punch 300. It will be appreciated that the distance extending toward the location of the round punch 300 is considered to be the height, i.e., the height of the shim 220 is greater than the depth of the cavity 110 and less than the height of the shim plate 210. Such a configuration allows the pad 220 to effectively fix the relative position of the pad 210, and at the same time, it is convenient for a person skilled in the art to replace the pad 220 without affecting the fixing of the pad 210 to the fixing base 230. Specifically, when the height of the spacer 220 is smaller than the depth of the cavity 110, the mounting and dismounting of the spacer 220 are very inconvenient, and when the height of the spacer 220 is larger than the height of the pad 210, the restriction of the pad 210 to the position of the fixing seat 230 is affected.

In the process of fixing the upper die holder 100 to the base plate 210 and the base plate 210 to the fixing base 230, nuts are typically used for fastening. The nut can be conveniently detached for maintenance when being firmly connected.

Although various specific embodiments are described in this application, the application is not limited to the details of the industry standard or examples, which are intended to indicate that the same, equivalent or similar embodiments or variations as described in the above examples may be achieved by the use of custom or modified embodiments. Examples of ways of data acquisition, processing, output, judgment, etc. using these modifications or variations are still within the scope of alternative embodiments of the present application.

Although the present application has been described by way of example, one of ordinary skill in the art will recognize that there are many variations and modifications to the present application without departing from the spirit of the present application, and it is intended that the appended embodiments include such variations and modifications without departing from the application.
