Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example:

[0025] Reference Figures 1-5 This device is an integrated flattening and punching machine, comprising a worktable 1 and a support frame 2. The support frame 2 is fixed on the worktable 1. A lower module is provided on the worktable 1. The lower module includes a lower fixed plate 3 and a lower support plate 4. The lower fixed plate 3 is fixed on the worktable 1, and the lower support plate 4 is located above the lower fixed plate 3. A plurality of sliding rods 10 are fixed on the side of the lower fixed plate 3 facing the lower support plate 4. A plurality of sliding grooves 11 are opened on the side of the lower support plate 4 facing the lower fixed plate 3. One end of each sliding rod 10 slides through one of the sliding grooves 11. A plurality of first clearance grooves 12 are opened on the side of the lower support plate 4 facing the lower fixed plate 3. A first spring 13 is fixed in each of the first clearance grooves 12. One end of each first spring 13 extends out of the first clearance groove 12 and is fixedly connected to one side of the lower fixed plate 3. This arrangement can effectively provide a certain elastic space between the lower fixed plate 3 and the lower support plate 4 through the sliding rods 10 and the first springs 13, thereby improving the service life of the overall lower module.

[0026] like Figure 1 and Figure 2 As shown, the lower support plate 4 has a mounting groove 5, and a fixing mold 6 for placing sheet material is detachably installed in the mounting groove 5. A first punch 21 is provided on the lower support plate 4 and at the bottom of the mounting groove 5. A connecting hole 22 is provided on the fixing mold 6, and a connecting sleeve 23 is provided in the connecting hole 22. The connecting sleeve 23 is snapped into and passes through the first punch 21. By replacing different fixing molds 6, different sheets can be effectively placed and positioned. The design of the connecting sleeve 23 facilitates the positioning of the fixing mold 6 in the mounting groove 5. The figure shows the maximum size of the fixing mold 6.

[0027] like Figure 1 and Figure 4 As shown, the support frame 2 is equipped with an upper module, which includes an upper fixed plate 7 and an upper support plate 8. The upper fixed plate 7 is located on the support frame 2, and the upper support plate 8 is located below the upper fixed plate 7, with the upper support plate 8 corresponding vertically to the fixed mold 6. Several upper sliding rods 14 are fixedly mounted on the side of the upper fixed plate 7 facing the upper support plate 8. Several upper sliding grooves 15 are opened on the side of the upper support plate 8 facing the upper fixed plate 7. One end of each of the upper sliding rods 14 slides through one of the upper sliding grooves 15. Several second clearance grooves 16 are opened on the side of the upper support plate 8 facing the upper fixed plate 7. A second spring 17 is fixedly mounted in each of the second clearance grooves 16, and one end of each of the second springs 17 extends out of the second clearance groove 16 and is fixedly connected to one side of the upper fixed plate 7. The arrangement of the upper sliding rods 14, lower sliding rods 10, first springs 13, and second springs 17 further increases the elastic space and facilitates the demolding of the sheet after punching. Figure 1 and Figure 2 As shown, both the lower support plate 4 and the upper support plate 8 are equipped with electric heating plates 9. The electric heating plates 9 can effectively heat the sheet on the upper support plate 8 and the fixed mold 6 through heat conduction, which facilitates the improvement of the sheet flattening efficiency.

[0028] like Figure 1 and Figure 4 As shown, the support frame 2 is equipped with a lifting assembly for driving the upper module to move towards the fixed mold 6. The lifting assembly includes several lifting cylinders 18 and several connecting rods 19 with top caps. The lifting cylinders 18 are all mounted on the support frame 2, and the telescopic ends of the lifting cylinders 18 all face the worktable 1. The upper fixed plate 7 has several countersunk holes 20. The connecting rods 19 slide through the countersunk holes 20 and are threadedly connected to the telescopic ends of the lifting cylinders 18. This arrangement effectively allows the connecting rods 19 to pass through the countersunk holes 20, so that the top caps on the connecting rods 19 abut against the steps on the countersunk holes 20, and the upper fixed plate 7 is fixed by the threaded connection with the telescopic ends of the lifting cylinders 18.

[0029] like Figure 1 and Figure 2 As shown, the support frame 2 is equipped with a punching assembly for punching sheets. The punching assembly includes a punching cylinder 25 and a punch 26. The punching cylinder 25 is mounted on the support frame 2, with its telescopic end facing the worktable 1. The punch 26 is detachably mounted on the telescopic end of the punching cylinder 25. This mounting method is existing technology, and its structure will not be described in detail here. The punch 26 slides sequentially through the upper fixed plate 7 and the upper support plate 8 and extends into the first punch hole 21. This arrangement facilitates the punch 26 in punching the sheets, and the length of the punch 26 is greater than the overall width of the upper module.

[0030] like Figure 5 As shown, a discharge channel 24 is provided on the lower fixed plate 3, which corresponds vertically to and is connected to the first punch 21. The discharge channel 24 is an open design, with the openings gradually increasing in size towards the outside, which facilitates the discharge of waste material after punching. The lower fixed plate 3 is also provided with a ventilation slot that communicates with the discharge channel 24, allowing personnel to use an air gun to blow air into the discharge channel 24.

[0031] Working principle:

[0032] During installation, firstly, select a suitable fixed mold 6 according to the size of the sheet material. Then, attach the fixed mold 6 to the first punch 21 on the lower support plate 4 through the connecting sleeve 23. Finally, place the sheet material on the fixed mold 6. When flattening, the upper support plate 8 moves towards the fixed mold 6 by extending and retracting the lifting cylinder 18 until the sheet material is flattened. The sheet material is further heated by the electric heating plate 9 to better flatten and shape the sheet material. When punching, install the punch 26 required by the process on the extension end of the punching cylinder 25. Then, the punch 26 is driven by the punching cylinder 25 to pass through the upper fixed plate 7 and the upper support plate 8 in sequence, and punch the sheet material between the upper support plate 8 and the fixed mold 6.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
