The two sliding seats 4 move relative to each other, thereby driving the multiple flange plates 3 of the two movable supports 2 to move toward or away from each other, so that the tops of the multiple flange plates 3 of the two movable supports 2 are surrounded to form a V-shaped groove d aligned with the upper die of the bending machine, and the depth of the V-shaped groove d can be adjusted according to the thickness of the plate to be processed.

[0043] See also Figures 1 to 3As shown, as a preferred embodiment, the sliding seat 4 is formed with a mounting hole passage penetrating through opposite ends of the sliding seat 4. A plurality of slots f communicating with the mounting hole passage are formed in the top of the sliding seat 4, and the plurality of slots f are arranged at intervals along the length direction of the sliding seat 4. A plug plate 33 is formed at the bottom of the end of the plug-in portion 31 away from the flange plate 3, and a positioning through hole g is formed in the middle of the plug plate 33.

[0044] When installing the plug-in portions 31 of the plurality of flange plates 3 of the movable support 2 on the sliding seat 4, first, the plug plates 33 of the plug-in portions 31 of the plurality of flange plates 3 are respectively inserted into the plurality of slots f of the sliding seat 4. At this time, the positioning through hole g of the plug plate 33 is aligned with the mounting hole passage of the sliding seat 4; then the tension rod 6 is passed through the mounting hole passage and the positioning through holes g of the plurality of plug plates 33, and both ends of the tension rod 6 are locked, so that the plug-in portions 31 of the plurality of flange plates 3 of the movable support 2 are detachably installed on the sliding seat 4, realizing the locking of the plug-in portion 31 and the sliding seat 4.

[0045] As a preferred embodiment, a plurality of receiving grooves are formed in the top of the workbench 1, and a plurality of balls 11 are rotatably installed in the plurality of receiving grooves respectively. The balls 11 in the plurality of receiving grooves support the movable support 2, the flange plate 3 and the plug-in portion 31 of the flange plate 3. With the assistance of the balls 11, when adjusting the depth of the V-shaped groove d, the movable support 2, the flange plate 3 and the plug-in portion 31 of the flange plate 3 can reduce the frictional loss with the workbench 1 and can move more smoothly.

[0046] As a preferred embodiment, a roller 21 is rotatably installed on the top of the movable support 2, and the roller 21 is arranged along the length direction of the movable seat 2. By providing the roller 21, when bending the plate, the scratching damage to the bottom of the plate can be reduced.

[0047] For the lower die with adjustable shaping groove depth for the bending machine of the present utility model, by arranging the plurality of flange plates 3 of the two movable supports 2 in a staggered manner, and inserting the plug-in portion 31 of the flange plate 3 into the vertical through groove a of another movable support and extending out from the notch b at the bottom of another movable support, a V-shaped groove d is formed by enclosing between the tops of the plurality of flange plates 3 of the two movable seats 2. By detachably installing the extended plug-in portion 31 on the sliding seat 4, and driving the two sliding seats 4 to approach or depart from each other through the driving mechanism 5, the depth of the V-shaped groove d is adjusted, so as to meet the bending requirements of plates with different thicknesses.

[0048] The lower die with adjustable plastic shaping groove depth for a bending machine of the present utility model connects the insertion part of the flange plate 3 and the sliding seat 4 by inserting the insertion plate 33 at the bottom of the insertion part 31 into the slot f of the sliding seat 4 and locking the two with the tension screw 6. When the lower die needs to be cleaned and maintained (rusty bending plates will drop debris into the V-shaped groove d, and after long-term use, the lower die needs to be cleaned), the locking of the sliding seat 4 to the insertion part 31 is released by removing the tension screw 6, and then the flange plates 3 of the two movable supports 2 can be quickly separated and cleaned.

[0049] For the lower die with adjustable plastic shaping groove depth for a bending machine of the present utility model, the flange plates 3 of the two movable supports 2 (including the insertion part 31 of the flange plate 3) are matched through the limiting rib 32 and the slot e. On the one hand, it can make the relative displacement of the flange plates 3 of the two movable supports 2 more stable. On the other hand, the mutually matched limiting rib 32 and slot e can limit the vertical displacement of the flange plate 3, so that the lower die with adjustable plastic shaping groove depth for a bending machine of the present utility model has a more stable use state.
