Description

Technical Field

[0001] This utility model belongs to the field of bending mold technology, specifically relating to a bending and forming mold. Background Technology

[0002] In the field of industrial manufacturing, especially in bending processing, bending forming dies play a crucial role. For example, the existing patent with publication number CN115608821B discloses "a contouring arc forming die, which includes a bending upper die and a bending lower die, with an upper die head provided at the bottom of the bending upper die, and a bending cavity corresponding to the upper die head on the bending lower die, and also includes a lower die base, an elastic component and a corner-rubbing punch, with the corner-rubbing punch fixed on the lower die base". It can be seen that the application describes a common bending forming die, which is mainly composed of a bending die head and a bending die base. The bending die head is installed on the drive device of the bending machine, and can be lowered to bend the sheet metal placed on the bending die base.

[0003] In the existing technology of bending and forming molds, the lower end of the bending die head is prone to wear after repeated processing. Since the easily worn lower end of the bending die head of the existing bending and forming mold cannot be replaced separately, the entire bending die head must be disassembled and replaced, resulting in unnecessary waste of resources and increased maintenance costs. Therefore, this utility model aims to improve and optimize the existing bending and forming mold. Utility Model Content

[0024] Example

[0025] Please see Figures 1 to 4 This is an embodiment of the present utility model, which provides a technical solution: a bending arc forming mold, comprising...

[0026] Curved mold base 1;

[0027] And a detachable bending die assembly disposed above the curved die base 1, including an upper die base 21, a mounting base 23 welded and fixed to the top of the upper die base 21, a detachable curved die head 22 installed at the bottom of the upper die base 21, a connecting insert plate 221 welded and fixed to the top surface of the detachable curved die head 22, and a connecting slot 211 opened on the bottom surface of the upper die base 21 for the connecting insert plate 221 to be inserted into, and the connecting insert plate 221 is inserted into the connecting slot 211;

[0028] And two rectangular inserts 4, the surface of the connecting plate 221 is provided with two through holes 222 for the rectangular inserts 4 to pass through, and the two sides of the upper mold base 21 are provided with two side insertion holes 212 for the rectangular inserts 4 to be inserted, and the side insertion holes 212 communicate with the connecting slot 211. The rectangular inserts 4 pass through the connecting plate 221 through the through holes 222, and the two ends of the rectangular inserts 4 are respectively in the two side insertion holes 212, so that the connecting plate 221 and the upper mold base 21 can be connected by the rectangular inserts 4.

[0029] The system includes a limiting mechanism, comprising two cylindrical rotating seats 32 rotatably mounted on both sides of the mounting base 23, and a limiting baffle 31 welded and fixed to the side of the cylindrical rotating seats 32. The bottom end of the limiting baffle 31 extends to the side of the upper mold base 21, covering the two side insertion holes 212, which can effectively block and limit the rectangular insert 4, ensuring the connection stability between the detachable arc mold head 22 and the upper mold base 21. When the detachable arc mold head 22 needs to be disassembled in the future, the limiting baffle 31 can be rotated and removed to pull out the rectangular insert 4 and quickly separate the detachable arc mold head 22 from the upper mold base 21, thereby realizing the individual replacement of the detachable arc mold head 22.

[0030] In this embodiment, preferably, a cylindrical shaft block 36 is rotatably provided inside the mounting base 23, and the two ends of the cylindrical shaft block 36 pass through to both sides of the mounting base 23 and are fixed to the two cylindrical rotating seats 32, so that the cylindrical shaft block 36 can rotate smoothly on the side of the mounting base 23, and the two cylindrical rotating seats 32 and the limiting baffle 31 can rotate together.

[0031] In this embodiment, preferably, the position of the through hole 222 corresponds to the position of the side insertion hole 212, so that the rectangular insertion rod 4 can pass through smoothly.

[0032] In this embodiment, preferably, the limiting mechanism further includes an inner sliding groove 38 opened inside the cylindrical rotating seat 32, an inner sliding seat 310 slidably disposed in the inner sliding groove 38, a limiting rod 34 welded and fixed to the bottom of the inner sliding seat 310, and a limiting slot 37 opened on the top surface of the upper mold base 21 and corresponding to the limiting rod 34. The bottom end of the limiting rod 34 penetrates to the bottom of the cylindrical rotating seat 32 and is inserted into the limiting slot 37. It can stably limit the cylindrical rotating seat 32 and the limiting baffle 31 during daily use, ensuring the blocking stability of the limiting baffle 31 on the rectangular insert 4, thereby ensuring the assembly stability between the detachable arc-shaped mold head 22 and the upper mold base 21.

[0033] In this embodiment, preferably, a spring 39 is also provided in the inner slide groove 38 relative to the top of the inner slide block 310. Under the push of the spring 39, the bottom end of the daily use stability limiting lever 34 can be stably inserted into the limiting slot 37 and will not move out on its own.

[0034] In this embodiment, preferably, a connecting rod 35 is fixed to the top of the inner slide 310, and the top end of the connecting rod 35 extends through to the top of the cylindrical rotating seat 32. A movable L-shaped movable plate 33 is provided on one side surface of the limiting baffle 31. The top end of the L-shaped movable plate 33 bends inward and extends to the top of the cylindrical rotating seat 32, and the top end of the connecting rod 35 is fixed together with the top end of the L-shaped movable plate 33. This allows the operator to push the L-shaped movable plate 33 upward, causing the connecting rod 35 to move the inner slide 310 and the limiting rod 34 upward, causing the spring 39 to be gradually compressed until the bottom end of the limiting rod 34 moves out of the limiting slot 37. At this point, the cylindrical rotating seat 32 and the limiting baffle 31 are no longer limited, and the limiting baffle 31 can be rotated away from the side of the upper mold base 21 to realize the rectangular insert rod. After the removal of 4, once the replacement of the detachable arc-shaped mold head 22 is completed, the connecting plate 221 at the top of the detachable arc-shaped mold head 22 can be inserted into the connecting slot 211. Then, the two rectangular inserts 4 pass through the two through holes 222 through the side insertion holes 212 respectively, so that the two ends of the rectangular inserts 4 can be in the side insertion holes 212 on both sides of the upper mold base 21, thus completing the insertion of the connecting plate 221 and the upper mold base 21. At this time, the L-shaped movable plate 33 is lifted up, and the limiting baffle 31 is rotated back to the side of the upper mold base 21 to block the side insertion holes 212 again. Then, the L-shaped movable plate 33 is released, and under the push of the spring 39, the inner slide 310 moves down with the limiting rod 34 to reset, so that the bottom end of the limiting rod 34 is inserted into the limiting slot 37, thus limiting the cylindrical rotating seat 32 and the limiting baffle 31 again.

[0035] In this embodiment, preferably, a rectangular dial is provided on the bottom side of the L-shaped movable plate 33, which facilitates the subsequent operation of the L-shaped movable plate 33 by the operator.

[0036] In this embodiment, preferably, the surface of the mounting substrate 23 is provided with a plurality of reserved mounting holes for connecting the mounting substrate 23 to the drive end on the bending machine.

[0037] In summary, when performing bending processing, first connect the mounting base 23 to the drive end of the bending machine, then place the plate to be bent on top of the bending die 1, and start the bending machine, so that the upper die 21 and the detachable arc-shaped die head 22 move down, causing the detachable arc-shaped die head 22 to press the plate into the arc-shaped notch at the top of the bending die 1, thus performing bending processing on the plate.

[0038] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
