Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is also to be understood that the terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used in the specification of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in this specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items and includes such combinations.

Referring to fig. 1 and 2, a first embodiment of the present invention discloses a continuous progressive blanking die 1 with freely switchable punches, including a bearing plate 11, a pulling assembly 12, a pulling plate 13, a top block 14 and a punch 15, wherein the pulling assembly 12 and the pulling plate 13 are disposed on the bearing plate 11, the pulling assembly 12 is connected to the pulling plate 13, the pulling assembly 12 drives the pulling plate 13 to slide, the pulling plate 13 is provided with a groove 131, one end of the top block 14 is connected to the punch 15, the other end of the top block is provided with a protrusion 141, and the protrusion 141 is disposed in the groove 131.

It can be understood that the pulling assembly 12 drives the pulling plate 13 to move so as to adjust the relative position of the groove 131 and the protrusion 141, specifically, when the bearing plate 11 is separated from the lower die in the die, the punch 15 slides downward due to gravity, so that the groove 131 is separated from the protrusion 141, at this time, the pulling plate 13 is driven to continue to move (as shown in a direction in fig. 2), so that the groove 131 is misaligned with the protrusion 141, when the punching operation is performed, the bearing plate 11 moves downward, when the punch 15 contacts the material to be formed, since the groove 131 is misaligned with the protrusion 141, at this time, the protrusion 141 abuts against the surface of the pulling plate 13 (as shown in the abutting state in fig. 2), so that the ejector block 14 is limited, and the punch 15 cannot be retracted to complete the punching operation. On the contrary, if the pulling plate 13 moves to align the protrusion 141 and the groove 131 in the vertical direction, when the punch 15 moves downward to contact the material to be formed, the protrusion 141 is recovered into the groove 131 due to the receiving function of the groove 131, and the punch 15 may continue to contract in length, that is, the punch 15 cannot complete the punching operation at present, and the switch of the punch 15 is completed.

It can be understood, through setting up arm-tie 13, and set up recess 131 on arm-tie 13, and set up kicking block 14 in drift 15 one end, set up protruding 141 and recess 131 cooperation on kicking block 14, the flexible stroke of control drift 15 of the effect of accomodating through recess 131, with the user state of freely switching drift 15, make on same mould, adopt simple sliding construction to accomplish and carry out the punching press to the product of different styles, need not die sinking again or the new mould of dismouting, the work efficiency is improved, the human cost is reduced. Meanwhile, the inner punch 15 of the die is independently switched, so that various die combinations can be obtained in a complex die, complex form switching can be realized, and the stamping requirement of products of various styles can be met. Further, due to the simple structure of the switching punch 15, the structure has a low failure rate, and the maintenance and the repair of a user are facilitated.

It is understood that the carrier plate 11 further includes a sliding hole 111, the top block 14 and the punch 15 are disposed in the sliding hole 111, and the top block 14 and the punch 15 slide in the sliding hole 111 to define the moving direction of the top block 14 and the punch 15.

Specifically, when the protrusion 141 abuts against the side surface of the pulling plate 13 (i.e. the protrusion 141 abuts against the area outside the groove 131), the punch 15 is exposed out of the sliding hole 111 for performing the punching operation, and when the protrusion 141 is disposed in the groove 131, the punch 15 is disposed in the sliding hole 111.

With reference to fig. 1, the pulling assembly 12 includes an air cylinder 121 and a pulling plate hook 122, the air cylinder 121 pulls the pulling plate hook 122 to move, the pulling plate hook 122 is connected to the pulling plate 13, the pulling plate hook 122 drives the pulling plate 13 to move horizontally, and the air cylinder 121 is used for providing sliding power to the pulling plate 13.

Optionally, as an embodiment, the edge of the protrusion 141 is provided with a chamfer or a fillet structure, and correspondingly, the edge of the groove 131 is also provided with a chamfer or a fillet structure, so that the protrusion 141 and the groove 131 can be separated from each other or can be accommodated in contact with each other based on the guiding function of the chamfer or the fillet structure when in contact.

through setting up the arm-tie to set up the recess on the arm-tie, and set up the kicking block in drift one end, set up arch and recess cooperation on the kicking block, through the stroke of the nimble control drift of the effect of accomodating of recess, with the user state of freely switching the drift, make on same mould, adopt simple sliding construction to accomplish and carry out the punching press to the product of different styles, need not die sinking again or the new mould of dismouting, improved work efficiency, reduced the human cost. Meanwhile, through independent switching of the inner punch of the die, the method can be applied to complex dies to obtain various die combinations, can realize complex form switching, and meets the requirement of stamping of products of various styles. Further, due to the fact that the structure of the switching punch is simple, the structure has a low failure rate, and overhauling and maintenance of a user are facilitated.

While the utility model has been described with reference to specific embodiments, the utility model is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the utility model. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
