[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0036] Reference Figure 1-8 A sheet metal clamping device for a sheet metal bending machine includes a bottom plate 1, a height plate 2 fixed on one side above the bottom plate 1, and a horizontal top plate 3 fixed on the inner side above the height plate 2.

[0037] Among them, the height plate 2 and the horizontal top plate 3 are a right-angle structure arranged in one piece; the two cooperate with the bottom plate 1 to form a C-shaped opening structure.

[0038] Preferably, Figure 5 As shown, the lower end of the height plate 2 is provided with a bent edge that fits with the bottom plate 1 ; thereby increasing the connection surface with the bottom plate 1 , and the connection strength between the two is higher and more reliable.

[0039] A plurality of telescopic mechanisms 4 are arranged above the horizontal top plate 3 , and the output ends of the telescopic mechanisms 4 are connected to holding plates 5 ; the holding plates 5 are driven to move by the telescopic mechanisms 4 , thereby clamping the workpiece.

[0040] Preferably, the telescopic mechanism 4 adopts a hydraulic cylinder with sufficient pressure output.

[0041] Furthermore, a rubber anti-skid plate 6 is provided above the bottom plate 1 to reduce the rigid contact and damage between the workpiece and the bottom plate 1 .

[0042] It is understandable that the workpiece needs to be placed above the base plate 1 before clamping; at this time, rigid contact and damage may occur; as for the bottom of the pressure plate 5, it slowly descends and presses on the workpiece; relatively speaking, no special design is required to prevent rigid contact; of course, a rubber anti-slip plate 6 can also be set below the pressure plate 5.

[0043] In some embodiments, 7-shaped reinforcement ribs 7 are provided on the outer sides of the height plate 2 and the horizontal top plate 3 .

[0044] like Figure 2 , 5 As shown; by setting up multiple 7-shaped reinforcing ribs 7, the strength and deformation resistance of the horizontal top plate 3 can be significantly improved, the whole is more reliable, and can bear greater pressure.

[0045] In some embodiments, a reinforcement strip 8 is disposed above the holding plate 5 .

[0046] Specifically, the reinforcing strip 8 includes a plurality of closed elliptical strips 81 and a long horizontal strip 82 connecting the plurality of elliptical strips 81 ; and further includes short vertical strips 83 crisscrossing the long horizontal strips 82 .

[0047] like Figure 7 , 8 As shown, the strength and overall deformation resistance of the holding plate 5 are improved by the structural arrangement of the reinforcing strip 8 .

[0048] Furthermore, a circular ring 84 is disposed at the center of the elliptical strip 81 ; radial strips 85 connected to the elliptical strip 81 are disposed outside the circular ring 84 , which further strengthens the elliptical strip 81 .

[0049] Correspondingly, the output end of the telescopic mechanism 4 is clamped and fixed in the ring 84 .

[0050] In some embodiments, a plurality of rows of through-going limiting holes 9 are correspondingly provided on the horizontal top plate 3 and the holding plate 5 ; correspondingly, limiting pins 10 are inserted into the limiting holes 9 .

[0051] It should be noted that the clamping depths for different workpieces are different; conventionally, the distance that the workpiece enters below the holding plate 5 is controlled by relying on the operator's experience or other auxiliary components.

[0052] In the above embodiment, the depth of entry of the workpiece is limited by the preset limiting hole 9 in combination with the slidably arranged limiting pin 10 ; meanwhile, the setting of the limiting pin 10 does not affect the normal operation of the holding plate 5 .

[0053] As in Figure 1 The limit pin 10 is inserted into the limit hole 9 in the frontmost row.

[0054] In addition, for workpieces of different widths, limiting pins 10 can be inserted into the two longitudinal rows of limiting holes 9 to limit the positions of both ends, making the operation more convenient.

[0055] Preferably, a large head 11 is provided at the top of the limiting pin 10, thereby increasing the weight of the top, causing it to fall under the action of gravity and not easily move upward.

[0056] Furthermore, a groove 61 corresponding to the limiting hole 9 is formed on the rubber anti-slip plate 6, which makes it easier for the limiting pin 10 to be in place.

[0057] When the utility model is used, the limiting pin 10 is pre-inserted according to the entry depth and width of the workpiece to limit the workpiece; after the workpiece is placed in place, the holding plate 5 is driven downward by the telescopic mechanism 4 to clamp the workpiece.

[0058] In the utility model, the bottom plate 1, the height plate 2 and the horizontal top plate 3 cooperate to form a C-shaped opening structure; the overall structure is simple and has reliable strength; 7-shaped reinforcing ribs are arranged on the outside to significantly improve the strength and deformation resistance of the horizontal top plate 3, making the whole more reliable and capable of bearing greater pressure; reinforcing strips 8 are arranged on the holding plate 5, and the strength and overall deformation resistance of the holding plate 5 are improved through the structural arrangement of the reinforcing strips 8; a rubber anti-skid plate 6 is arranged on the bottom plate 1 to reduce the rigid contact and damage between the workpiece and the bottom plate 1; a plurality of rows of through-limiting holes 9 are arranged to limit the position of workpieces of different widths and entry depths, making the operation more convenient.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
