[0040] like Figure 1 and Figure 2 As shown, a clamping device for metal stamping parts processing includes: a clamping assembly 100 and a bracket assembly 200, wherein the clamping assembly 100 is arranged on the bracket assembly 200, wherein:

[0041] like Figure 3 As shown, the clamping assembly 100 includes: a first connecting rod 101, a second connecting rod 102, a third connecting rod 103, a first connecting block 104, a second connecting block 105, a U-shaped first mounting plate 106, a cylinder 107 and two third connecting blocks 108, wherein:

[0042] The two ends of the first connecting rod 101 are respectively connected to the middle of the first connecting block 104 and the middle axis of the first mounting plate 106, the second connecting block 105 is arranged in the middle area of ​​the first mounting plate 106, the two ends of the second connecting rod 102 are respectively connected to the first connecting block 104 and the second connecting block 105, the third connecting rod 103 is arranged between the first connecting rod 101 and the second connecting rod 102, and the two ends of the third connecting rod 103 are respectively connected to the middle of the first connecting rod 101 and the second connecting block 105;

[0043] The cylinder 107 is arranged below the second connection block 105, the end of the movable rod of the cylinder 107 is connected to the second connection block 105, and two third connection blocks 108 are respectively arranged on the cylinder 107;

[0044] The first mounting plate 106 and the third connecting block 108 are respectively connected to the bracket assembly 200 .

[0045] In the embodiment of the utility model, the relevant staff prepares two clamping devices for processing metal stamping parts disclosed in the utility model according to the actual situation, and symmetrically places the two clamping devices for processing metal stamping parts on both sides of the mold to clamp the upper plate of the mold;

[0046] Specifically, first, the relevant staff installs the clamping device for metal stamping parts processing on the punch press, wherein the cylinder 107 is connected to the punch press through the third connecting block 108, and the first mounting plate 106 is fixedly installed on the punch press by bolts;

[0047] Next, the relevant staff will place the plate on the mold and align the positioning block on the mold so that the plate is laid flat in the appropriate position;

[0048] Then, the relevant staff starts the cylinder 107 to move the movable rod of the cylinder 107 upward.

[0049] The movable rod 107 drives the second connecting block 105 to move upward;

[0050] During this process, the second connecting block 105 moving upward will drive the second connecting rod 102 and the third connecting rod 103 to move upward, and the third connecting rod 103 moving upward will push the first connecting rod 101 to rotate around the axial connection between the second connecting rod 102 and the first mounting plate 106, and the second connecting rod 102 will also push the first connecting block 104 to rotate around the axial connection between the second connecting rod 102 and the first connecting rod 101 during the upward rising process;

[0051] Finally, the first connecting block 104 will tightly clamp the sheet on the mold, and the relevant staff can start the punch press to punch the sheet.

[0052] The clamping device for processing metal stamping parts disclosed in the utility model can stably clamp the stamping plate and has the advantages of being flexible and convenient to use.

[0053] In order to better explain the present invention, in one embodiment of the present invention, as shown in FIG. Figure 4 As shown, the support assembly 200 includes: a plurality of legs 201, a plurality of fixing beams 202 and a mounting beam 203, wherein:

[0054] The plurality of legs 201 are fixedly connected to each other via a fixing beam 202 , the mounting beam 203 and the first mounting plate 106 are respectively connected to the upper ends of the legs 201 , and the third connecting block 108 is connected to the legs 201 .

[0055] like Figure 5 As shown, the workbench assembly 300 is arranged on the support assembly 200, wherein,

[0056] The workbench assembly 300 includes: a second mounting plate 301, two bearing seats 302, two fourth connecting rods 303, two sliders 304, a threaded rod 305, a slide rail 306 and a hand wheel 307, wherein the two sides of the threaded rod 305 are respectively provided with thread lines with opposite spiral directions, wherein:

[0057] The two bearing seats 302 are respectively arranged on the second mounting plate 301;

[0058] The threaded rod 305 and the slider 304 are arranged parallel to each other, the two ends of the threaded rod 305 are respectively arranged on the two bearing seats 302, and the hand wheel 307 is arranged at the end of the threaded rod 305;

[0059] The two sliders 304 are respectively arranged on the slide rails 306 , and the threaded rods 305 respectively penetrate the two sliders 304 . The two ends of the fourth connecting rod 303 are respectively connected to the second mounting plate 301 and the slider 304 axis.

[0060] In the embodiment of the utility model, the bracket assembly 200 can be used to better install the clamping assembly 100 on the punch press;

[0061] The workbench assembly 300 can better enable the clamping assembly 100 to use plates of various thicknesses;

[0062] For example, when the thickness of the plate is relatively large, the relevant staff can turn the hand wheel 307 to drive the threaded rod 305 to rotate. The threaded rod 305 will drive the two sliders 304 to move away from each other during the rotation process. The two sliders 304 will drive the second mounting plate 301 to descend through the fourth connecting rod 303 during the process of moving away from each other. At this time, a large distance will be left between the second mounting plate 301 and the first connecting block 101.

[0063] When the thickness of the plate is small, the relevant staff can turn the hand wheel 307 and use 307 to drive the threaded rod 305 to rotate in the opposite direction to the above. During the rotation, the threaded rod 305 will drive the two sliders 304 to approach each other. During the process of approaching each other, the two sliders 304 will drive the second mounting plate 301 to rise through the fourth connecting rod 303. At this time, a small distance will be left between the second mounting plate 301 and the first connecting block 101.

[0064] In order to better explain the present invention, in one embodiment of the present invention, a fixing plate is disposed on a side of the first connecting block 104 away from the second connecting rod 102 , and the fixing plate is disposed directly above the first mounting plate 106 .

[0065] In addition, as a possibility, a side of the fixing plate close to the second mounting plate 301 and a side of the second mounting plate 301 close to the fixing plate are both provided with a rubber anti-slip layer.

[0066] Furthermore, the cross section of the first connection block 104 is arcuate.

[0067] In the embodiment of the utility model, the fixing plate and the second mounting plate 301, as well as the anti-slip layer on the fixing plate and the second mounting plate 301, are used to better fix the plate. At the same time, the first connecting block 104 with a bow-shaped cross-section can also make the first connecting block 104 have better structural strength, thereby further ensuring the effect of clamping the plate.

[0068] In summary, the clamping device for processing metal stamping parts disclosed in the utility model can stably clamp the stamping plate and has the advantages of being flexible and convenient to use.
