Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1 - Figure 5 An adjustable punching die for a bending machine includes a main body box 1. A groove 101 is formed inside the main body box 1. A first hydraulic cylinder 2 is fixedly installed on the top of the groove 101. A connecting block 5 is provided at the top of the first hydraulic cylinder 2. A first adjusting mechanism 6 is fixedly installed at the bottom of the connecting block 5. Wherein:

[0024] A workbench 7 is fixedly installed at the bottom end of the groove 101, and a second adjustment mechanism 9 is provided at the upper end of the workbench 7;

[0025] The first adjustment mechanism 6 includes a guide rail 61 fixedly installed at the bottom of the connecting block 5. A first slider 62 is symmetrically installed on the outer side of the guide rail 61. A guide rod 63 is provided on one side of the first slider 62.

An upper mold 66 is fixedly installed at the bottom of the first slider 62.

[0026] Furthermore, a fixed plate 8 is slidably mounted on the workbench 7. The upper end of the fixed plate 8 is provided with a sliding groove 81. The second adjustment mechanism 9 includes a drive motor 91 fixedly mounted on one side of the fixed plate 8. The output end of the drive motor 91 is fixedly connected to a bidirectional threaded rod 92. A second slider 93 is threadedly connected to the outer side of the bidirectional threaded rod 92. A lower mold 94 is fixedly connected to one side of the second slider 93. The lower mold 94 is slidably mounted inside the sliding groove 81. The bidirectional threaded rod 92 can drive two sets of second sliders 93 to move relative to each other, thereby adjusting the distance between the lower molds 94.

[0027] Furthermore, the second slider 93 is symmetrically arranged outside the bidirectional threaded rod 92, the lower mold 94 is symmetrically arranged inside the slide groove 81, the connecting plate 64 is L-shaped, and the side of the first slider 62 away from the connecting plate 64 is slidably mounted on the outside of the guide rod 63. The connecting plate 64 is L-shaped to facilitate the cylinder push rod 65 to push the connecting plate 64, thereby pushing the first slider 62 to slide and driving the upper mold 66 to slide, thereby adjusting the distance between the upper molds 66 to cope with punching processing of different spacings. The guide rod 63 plays a guiding role for the first slider 62 and can make the first slider 62 slide more smoothly.

[0028] Furthermore, the working end of the first hydraulic cylinder 2 is fixedly connected to multiple sets of clamping blocks 3, and the bottom end of the clamping block 3 is fixedly installed with an mounting plate 4. A second hydraulic cylinder 42 is fixedly installed on one side of the mounting plate 4. The working end of the second hydraulic cylinder 42 passes through the mounting plate 4, and a bending component 43 is fixedly connected to the working end of the second hydraulic cylinder 42. The second hydraulic cylinder 42 is used to push the bending component 43 to bend the heat sink plate of the chassis after punching.

[0029] Furthermore, the upper end of the fixed plate 8 is provided with evenly distributed spring telescopic rods 82, the connecting block 5 is fixedly installed at the bottom end of the mounting plate 4, and the bottom end of the mounting plate 4 is provided with evenly distributed sleeves 41. The sleeves 41 are positioned corresponding to the spring telescopic rods 82, and the sleeves 41 cooperate with the spring telescopic rods 82 to reduce vibration when the first hydraulic cylinder 2 is working.

[0030] Furthermore, the bending member 43 is configured as a 3 / 4 cylinder, the internal working angle of the bending member 43 is configured as an arc, and one side corner of the fixing plate 8 is configured with an arc that cooperates with the bending member 43. The bending member 43 cooperates with the fixing plate 8 to bend the sheet material.

[0031] Furthermore, the second adjustment mechanism 9 is disposed inside the fixed plate 8. A material collection box 10 is slidably installed on the side of the fixed plate 8 away from the second adjustment mechanism 9. A control panel 11 is fixedly installed on one side of the main body box 1. The material collection box 10 is used to collect waste materials generated during punching, and the control panel 11 is used to adjust the distance between molds and control the operation of the machine.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In use, the operator first sets the parameters on the control panel 11 according to the required punching spacing on the heat sink of the chassis. Then, the operator places the required sheet material on the upper end of the fixed plate 8. Next, the first hydraulic cylinder 2 is started, which drives multiple sets of clamping blocks 3 to move longitudinally. The upper mold 66 is moved longitudinally through the mounting plate 4 and the connecting block 5. Then, the lower mold 94 set on the fixed plate 8 punches the sheet material. The sleeve 41 and the spring telescopic rod 82 are used for shock absorption. After the punching is completed, the waste material generated by punching falls into the collection box 10 through the lower mold 94 for waste collection. Then, the sheet material is moved for subsequent punching processing.

[0034] Furthermore, after the punching process is completed, the workers transport the sheet metal to the bending area for bending. By activating the second hydraulic cylinder 42, the working end of the second hydraulic cylinder 42 pushes the bending part 43 to move longitudinally, and the sheet metal is bent by cooperating with the corner of one side of the fixed plate 8. The arc set at the corner of the working surface of the bending part 43 cooperates with the arc set at the corner of one side of the fixed plate 8 to perform a 90-degree bend on the sheet metal. After one side is processed, the workers rotate the sheet metal to bend the other sides.

[0035] Furthermore, when other models of chassis heat sinks need to be processed, the operator sets the corresponding parameters on the control panel 11, then starts the cylinder push rod 65. The working end of the cylinder push rod 65 then pushes the connecting plate 64 to move, thereby causing the first slider 62 to slide on the guide rail 61 and slide with the guide rod 63, which in turn moves the upper mold 66. When the upper mold 66 reaches the designated position, the cylinder push rod 65 stops extending and retracting. At the same time, the drive motor 91 is started to drive the bidirectional threaded rod 92 to rotate, which in turn moves the second slider 93. Then, the second slider 93 drives the lower mold 94 to slide inside the groove 81 opened on the fixed plate 8. After the lower mold 94 is adjusted to the designated distance, the drive motor is turned off, and the operator can then perform punching and bending processing on the subsequent chassis heat sinks.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
