Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an adjustable mold. Background Technology

[0002] Bending dies are tools used by bending machines to shape and process sheet metal. These tools are composed of various parts, and different dies are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being formed. They are used to make the blank into a part with a specific shape and size under the pressure of the bending machine.

[0003] In the existing technology, bending dies can usually only process sheet metal into objects of a fixed shape during the processing of sheet metal. When it is necessary to process it into different shapes, the die needs to be replaced. Since the replacement takes a long time and requires constant debugging, the practicality of the die is reduced. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses an adjustable mold, including a mounting plate, the top of which is provided with an automatic bending mechanism;

[0006] The automatic bending mechanism includes a transmission rod that passes through and is rotatably connected to the middle of the mounting plate. A turntable is fixedly connected to the top of the transmission rod. A connecting plate is fixedly connected to the middle of the right outer wall of the turntable. A bending block is fixedly connected to the left side of the middle of the top wall of the connecting plate. A gear is fixedly connected to the bottom of the transmission rod. An L-shaped plate is fixedly connected to the left rear side of the top wall of the mounting plate. A fixing plate is fixedly connected to the front top of the L-shaped plate. A fixing block is fixedly connected to the middle of the top wall of the fixing plate. A bending mold is provided on the front side of the fixing block. Multiple sets of arc-shaped screws are threadedly connected to the front side of the turntable inside the mounting plate.

[0007] As a preferred embodiment of this utility model, an insert block is fixedly connected to the middle of the bottom wall of the bending mold, and an insertion hole is provided in the middle of the insert block.

[0008] As a preferred embodiment of this utility model, the insert block is slidably connected to the inside of the slot, and the slot is located on the front side of the middle of the top wall of the fixed plate.

[0009] As a preferred embodiment of this utility model, a through hole is provided in the middle of the front wall of the slot, and a plug rod is slidably connected through the inner side of the through hole, with the plug rod and the plug hole being fitted with a clearance.

[0013] The beneficial effects of this utility model are:

[0014] 1.

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1-4 As shown, this utility model provides an adjustable mold, including a mounting plate 1, with an automatic bending mechanism 2 provided on the top of the mounting plate 1;

[0024] The automatic bending mechanism 2 includes a transmission rod 3, which connects the fixed gear 4 and the turntable 5. The transmission rod 3 passes through and is rotatably connected to the middle of the mounting plate 1. The turntable 5 is fixedly connected to the top of the transmission rod 3. A connecting plate 6 is fixedly connected to the middle of the right outer wall of the turntable 5. The rotation of the transmission rod 3 can cause the turntable 5 and its outer connecting plate 6 to rotate. A bending block 7 is fixedly connected to the left side of the middle of the top wall of the connecting plate 6. The gear 4 is fixedly connected to the bottom end of the transmission rod 3. An L-shaped plate 8 is fixedly connected to the left rear end of the top wall of the mounting plate 1. A fixing plate 9 is fixedly connected to the front end of the top of the L-shaped plate 8. The L-shaped plate 8 connects and fixes the mounting plate 1 and the fixing plate 9. A fixing block 10 is fixedly connected to the middle of the top wall of the fixing plate 9. A bending mold 16 is provided on the front side of the fixing block 10. Multiple sets of arc-shaped screws 20 are threadedly connected to the front side of the turntable 5 inside the mounting plate 1. The rotation of the screws 20 will cause them to move up and down inside the mounting plate 1.

[0025] The bending die 16 has a fixedly connected insert block 14 in the middle of its bottom wall. The insert block 14 has an insertion hole 15 in the middle. Inserting the insert rod 13 into the insertion hole 15 can fix the insert block 14.

[0026] The insert 14 is slidably connected to the inside of the slot 11, which is located on the front side of the middle of the top wall of the fixing plate 9. The insert 14 is fixed inside the slot 11 to install and fix the bending mold 16.

[0027] The slot 11 has a through hole 12 in the middle of the front wall. A rod 13 is slidably connected through the inside of the through hole 12. The rod 13 is fitted with the insertion hole 15 with a clearance. After the rod 13 passes through the through hole 12, it is inserted into the insertion hole 15 inside the insertion block 14, which can fix the insertion block 14 inside the slot 11, thereby fixing the bending mold 16 to the top of the fixing plate 9.

[0028] Among them, a mounting block 17 is fixedly connected to the right side of the bottom wall of the mounting plate 1, and a cylinder 18 is fixedly connected to the middle of the rear wall of the mounting block 17. The operation of the cylinder 18 can move the toothed plate 19 back and forth. The cylinder 18 is the power component of the automatic bending mechanism 2.

[0029] Among them, the output end of the cylinder 18 is fixedly connected to the toothed plate 19, which meshes with the gear 4. During the movement of the toothed plate 19, the gear 4 can rotate, and the rotation of the gear 4 can bend the workpiece.

[0030] Among them, support rods 21 are fixedly connected to the four corners of the bottom of the mounting plate 1, and the gear 4 is located between the four sets of support rods 21. The support rods 21 can install and fix the mounting plate 1 and its top components.

[0031] Working principle: When the mold needs to be replaced, the insert rod 13 is pulled out from the inside of the through hole 12, and the insert rod 13 is separated from the insert hole 15. Then the insert block 14 is pulled out from the inside of the slot 11 to quickly replace the bending mold 16. After that, the workpiece is placed between the bending mold 16 and the fixed block 10 and the cylinder 18 is started. During the operation of the cylinder 18, the output end extends and retracts, causing the toothed plate 19 to move back and forth. The movement of the toothed plate 19 causes the gear 4 to rotate back and forth, which in turn drives the turntable 5 to rotate back and forth through the transmission rod 3, continuously repeating the bending steps. During the bending process, the screw 20 is rotated at different positions, so that the screw 20 moves upward inside the mounting plate 1 during the rotation. This can block the connecting plate 6 fixed to it during the rotation of the turntable 5, thereby controlling the rotation angle of the turntable 5 and adjusting the bending angle of the bending mold 16.
