Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a clamping device for an adjustable bending machine mold. Background Technology

[0002] Bending machines use dies to process metal sheets. Typically, the lower die engages with the bending machine surface via a slot. However, during bending, the lower die needs to be clamped to prevent slippage when the upper die presses against it. Existing clamps, due to their fixed structure, cannot adjust their clamping position. The length of the lower die varies depending on the length of the sheet metal. If the clamps cannot be adjusted, they cannot hold lower dies of different lengths, thus limiting the application range of the bending machine.

[0003] Existing bending machine die clamping devices often fail to meet diverse needs in practical use. On one hand, due to limitations in their structural design, it is difficult to achieve precise fit for bending dies of different sizes and specifications. This leads to difficulty in accurately aligning the die with the bending equipment during processing, severely impacting processing accuracy and potentially rendering some dies unusable due to incompatibility, significantly limiting the equipment's application range. On the other hand, existing clamping devices also present numerous inconveniences in terms of operation. Both fixing and disassembling the die often require multiple tools and a series of complex and cumbersome steps. This not only consumes significant time and labor costs, reducing work efficiency, but also places high demands on the operator's professional skills and proficiency, increasing the operational difficulty.

[0014] Compared with the prior art, this utility model provides an adjustable clamping device for bending machine dies, which has the following advantages:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] This utility model provides a technical solution: Example 1

[0027] Combination Figures 1 to 4 An adjustable bending machine die clamping device includes a worktable 3, a frame plate 4 fixedly connected to the top of the worktable 3, a bending device 5 fixedly connected to the top of the frame plate 4, a bending die 51 arranged below the bending device 5, the bending die 51 being arranged on the top of the worktable 3, a positioning mechanism 1 arranged on the rear side of the bending die 51, and a fixing mechanism 2 arranged on the front side of the bending die 51.

[0028] The positioning mechanism 1 includes a base assembly 11 and a positioning assembly 12. The base assembly 11 is located on the rear side of the bending die 51, and the positioning assembly 12 is located on the front side of the base assembly 11.

[0029] The base assembly 11 includes a fixed base 1101, which is fixedly connected to the inner rear side of the frame plate 4. A T-shaped retaining strip 1102 is fixedly connected to the front side of the fixed base 1101. The positioning assembly 12 includes a spacer 1201, which is slidably connected to the outer side of the T-shaped retaining strip 1102. The rear side of the spacer 1201 is in contact with the front side of the fixed base 1101. A second T-shaped retaining strip 1202 is fixedly connected to the front side of the spacer 1201. The second T-shaped retaining strip 1202 is exactly the same as the first T-shaped retaining strip 1102. A pad 1203 is slidably connected to the front side of the second T-shaped retaining strip 1202. The front side of the pad 1203 is in contact with the rear side of the bending mold 51.

[0030] Furthermore, while the spacer 1201 is slidably connected to the outside of the T-shaped clip 1102, the same spacer 1201 can also be slidably connected to the outside of the T-shaped clip 2 1202. According to the size of the bending die 51, the operator can adjust the position of the bending die 51 by splicing different numbers of spacers 1201 together, so that bending dies 51 of different lengths and widths can be aligned with the bending equipment 5 during use. This makes the device adaptable to bending dies 51 of different sizes, increasing the adaptability of the device. Moreover, the operator only needs to control the splicing of different numbers of spacers 1201 to complete the adjustment of the position of the bending die 51, which is simple to operate and convenient for the operator to use. Example 2

[0031] See Figure 1 , Figure 2 and Figure 5 Furthermore, based on Embodiment 1, the fixing mechanism 2 includes an adjustment component 21, a clamping component 22, and a limiting component 23. The adjustment component 21 is located on the front side of the worktable 3, the clamping component 22 is located on the rear side of the adjustment component 21, and the limiting component 23 is located on the left and right sides of the adjustment component 21.

[0032] Adjustment assembly 21 includes a fixing frame 2101, which is fixedly connected to the front side of the workbench 3. A fixing screw 2102 is fixedly connected to the top of the fixing frame 2101. A threaded rod 2103 is threadedly connected to the inner ring of the fixing screw 2102. A torsion ring 2104 is fixedly connected to the front side of the threaded rod 2103. Clamping assembly 22 includes a connecting rotating ring 2201, which is rotatably connected to the rear end of the threaded rod 2103. The rear side of the connecting rotating ring 2201 is fixedly connected to... A clamping plate 2202 is attached, with the rear side of the clamping plate 2202 fitting against the front side of the bending die 51. The limiting component 23 includes a limiting slide rod 2301, which is located on the left and right sides of the threaded rod 2103. The limiting slide rod 2301 is fixedly connected to the front side of the clamping plate 2202. A limiting piece 2302 is fixedly connected to the front side of the limiting slide rod 2301. A fixing plate 2303 is slidably connected to the outer ring of the limiting slide rod 2301, and the fixing plate 2303 is fixedly connected to the front side of the worktable 3.

[0033] Furthermore: After the bending die 51 is positioned, the operator only needs to rotate the torsion ring 2104 to control the clamping plate 2202 to move backward, so that the clamping plate 2202 and the pad strip 1203 cooperate to clamp and fix the bending die 51. The operator only needs to rotate the torsion ring 2104 forward and backward to control the clamping plate 2202 to move back and forth, which makes it easy for the operator to fix the bending die 51 and also easy for the operator to disassemble the bending die 51. The operation is simple and convenient for the operator to use.

[0034] In actual operation, when this device is in use and it is necessary to fix the bending die 51, the operator first places the bending die 51 on the top of the workbench 3, aligning the bending die 51 with the bending equipment 5. Then, the operator slides a spacer strip 1201 to the front of the T-shaped clip 1102, and then slides an appropriate number of spacers 1201 sequentially to the outside of the T-shaped clip 2 1202. Finally, the pad strip 1203 is slid to the outside of the T-shaped clip 2 1202, so that the bending die 51 is back against the front of the pad strip 1203. After this, the bending die 51 can be bent... Align the bending device 5, and then the operator rotates the torsion ring 2104. The rotation of the torsion ring 2104 controls the rotation of the threaded rod 2103. The threaded rod 2103 rotates and moves backward within the inner ring of the fixed screw cylinder 2102. The backward movement of the fixed screw cylinder 2102 drives the clamping plate 2202 to move backward through the connecting rotating ring 2201. The clamping plate 2202 moves backward and contacts the front side of the bending die 51, pushing the bending die 51 to move backward until the rear side of the bending die 51 is in contact with the front side of the pad strip 1203, and the torsion ring 2104 can no longer rotate. At this point, the fixing process of the bending die 51 is completed.
