The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] This utility model embodiment provides a pneumatic bending machine for processing fixed cards, such as Figures 1-6 As shown, the pneumatic bending machine for processing fixed cards includes:

[0029] The base 100 is provided with a locking groove 101 and a sliding groove 102. The locking groove 101 and the sliding groove 102 are connected. The sliding groove 102 is provided with a first mold plate 310 and a second mold plate 320 for processing and fixing cards.

[0030] A pneumatic assembly 200 includes a pneumatic push rod 210 and a connecting plate 220 disposed on the pneumatic push rod 210. One side of the pneumatic push rod 210 is embedded in a locking groove 101. The connecting plate 220 is fixedly connected to a base 100, specifically as follows: The base 100 is provided with a first fixed end block group 110 and a second fixed end block group 120. The first fixed end block group 110 includes end blocks disposed on both sides of the locking groove 101. The connecting plate 220 is connected to the end blocks. The first fixed end block group 110 and the second fixed end block group 120 have the same structure. There are two sets of connecting plates 220, and different connecting plates 220 are respectively fixedly connected to the first fixed end block group 110 and the second fixed end block group 120 by bolts.

[0031] The first mold plate 310 is connected to the end of the pneumatic push rod 210, and the second mold plate 320 is assembled in the sliding groove 102. During the processing, the pneumatic push rod 210 pushes the first mold plate 310 closer to the second mold plate 320 which is in a stationary state.

[0032] In this embodiment, the pneumatic bending machine for processing fixed cards adopts a detachable split structure to effectively combine the pneumatic component 200 and the base 100. The equipment has a simple structure and is easy to disassemble and maintain. The first mold plate 310 and the second mold plate 320 are placed on the pneumatic component 200 and the base 100 respectively. The processing of fixed cards is completed by the relative movement between the first mold plate 310 and the second mold plate 320. The overall structure of the equipment is simple and easy to carry and transfer.

[0033] In a preferred embodiment of this invention, the end face of the sliding groove 102 away from the engaging groove 101 is provided with a limiting groove 103, and the second mold plate 320 is provided with a limiting slider that is adapted to the limiting groove 103. The second mold plate 320 is engaged in the limiting groove 103 by the limiting slider. The end of the pneumatic push rod 210 is also provided with a push plate 230, and the first mold plate 310 is connected to the push plate 230 by bolts.

[0034] In this embodiment, the first mold plate 310 and the second mold plate 320 are respectively designed with a detachable structure and connected to the pneumatic component 200 and the base 100, which facilitates the replacement of the first mold plate 310 and the second mold plate 320 during the processing; the opening direction of the sliding groove 102 is the same as the opening direction of the limiting groove 103, which facilitates the replacement operation.

[0035] In this application, the first mold plate 310 has an arc-shaped protrusion, and the second mold plate 320 has a groove that matches the protrusion. After the fixed steel sheet to be processed is inserted into the sliding groove 102, the first mold plate 310 will push the fixed steel sheet to move towards the second mold plate 320. The squeezing effect of the first mold plate 310 and the second mold plate 320 will cause the arc-shaped protrusion and the groove to form a specific crease on the fixed steel sheet. When it is necessary to construct a fixed steel sheet with other shapes and structures, the first mold plate 310 and the second mold plate 320 can be replaced accordingly. For example, the end faces of the first mold plate 310 and the second mold plate 320 can adopt a right-angled folded line structure, which can process the planar fixed card into a right-angled fixed card.

[0036] In this embodiment, the width of the first mold plate 310 is the same as the width of the sliding groove 102. During the movement of the pneumatic component 200, the sliding groove 102 will limit the first mold plate 310, and the movement direction of the first mold plate 310 is not easily deviated.

[0037] As a preferred embodiment of this invention, the structure of the pneumatic push rod 210 is a prior art device. The connecting plate 220 involved in this application is connected to the side wall of the pneumatic push rod 210 by welding. The push rod of the pneumatic push rod 210 extends into the sliding groove 102, and a push plate 230 is arranged at the end of the push rod part of the pneumatic push rod 210.

[0038] The locking groove 101 is provided with a wire harness slot at the end away from the sliding groove 102 to accommodate the passage of the pipeline. The pipeline extending from the pneumatic push rod 210 is accommodated through the wire harness slot and reaches the locking groove 101 to complete the docking with the pneumatic push rod 210.

[0039] In a further preferred embodiment of the present invention, the sidewall of the sliding groove 102 is also provided with a lateral extension opening, and a fixing card exceeding the width of the sliding groove 102 extends out of the sliding groove 102 from the lateral extension openings on both sides.

[0040] In this embodiment, when the workpiece size is larger than the width of the sliding groove 102, and for some processing requirements where high precision is not required, the fixing card can extend from the lateral extension openings on both sides of the sliding groove 102 and place one side close to the second mold plate 320. It should be noted that before processing, the distance between the first mold plate 310 and the second mold plate 320 needs to be pre-adjusted to ensure that the fixing card is subjected to a certain squeezing force from the first mold plate 310 and the second mold plate 320 when inserted between them, so as to avoid the fixing card from shaking or shifting. During the forming process, the squeezing force increases, and the fixing card will be less likely to slip off.

[0041] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art can still combine, add, delete, or otherwise adjust the features of the various embodiments of this utility model according to the circumstances without conflict or creative effort, thereby obtaining different technical solutions that do not fundamentally depart from the concept of this utility model.
