Summary of the invention

When the two first sliders move close to each other, the first cutting edge and the third cutting edge will be squeezed toward the second cutting edge.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] The embodiment of the present application provides a Z-shaped cutting edge adjustment device, which can solve the problem that the existing cutting edge tools used in blanking die production are difficult to adjust and usually have a fixed angle shape, which is not easy to adapt to "Z" shapes of different shapes and angles.

[0034] See also Figure 1-4 As shown, the embodiment of the present application provides a Z-shaped cutting edge adjustment device, comprising:

[0035] The adjusting mechanism includes a mold base 1, two first sliders 2 slidably arranged on the mold base 1, a first cutting edge 31, a second cutting edge 32 and a third cutting edge 33 connected and linked to each other, and a driving mechanism for driving the first slider 2 to slide.

[0036] The first cutting edge 31 and the third cutting edge 33 are both slidably disposed on the first slider 2, the second cutting edge 32 is hinged between the first cutting edge 31 and the third cutting edge 33, and is rotatably connected to the mold base 1, and the first cutting edge 31, the second cutting edge 32 and the third cutting edge 33 can form a Z shape.

[0037] The first cutting edge 31 , the second cutting edge 32 and the third cutting edge 33 form a complete cutting edge, which needs to be transformed into a Z-shape with different angles to cut the mold during use.

[0038] The first sliding block 2 is driven by the driving mechanism so that the first cutting edge 31, the second cutting edge 32 and the third cutting edge 33 are mutually linked by force and can be adjusted to a Z shape with different angles.

[0039] When it is necessary to change the cutting edge of a different Z shape, the first slider 2 is driven by the driving mechanism to slide and change its position along the length direction of the mold base 1, and the first slider 2 drives the first cutting edge 31 and the third cutting edge 33 to move, so that the first cutting edge 31 and the third cutting edge 33 move on the first slider 2 along the width direction of the mold base 1. When the two first sliders 2 move close to each other, the first cutting edge 31 and the third cutting edge 33 are squeezed toward the second cutting edge 32. Because the second cutting edge 32 is rotatably connected to the mold base 1, the force applied by the first cutting edge 31 and the third cutting edge 33 to the second cutting edge 32 causes it to rotate on the mold base 1. At the same time, the rotation of the second cutting edge 32 drives the first cutting edge 31 and the third cutting edge 33 to move on the first slider 2 along the width direction of the mold base 1, and the first cutting edge 31 and the third cutting edge 33 are also affected by the second cutting edge 32 when they move synchronously with the first slider 2. The reaction force of the cutting edge 32 is squeezed and slid on the first slider 2, changing its position, and at the same time, it will also drive the second cutting edge 32 to rotate and adapt to and match the first cutting edge 31 and the third cutting edge 33. The first cutting edge 31, the second cutting edge 32 and the third cutting edge 33 are subjected to and transmitted to each other, thereby realizing the linkage between the first cutting edge 31, the second cutting edge 32 and the third cutting edge 33, that is, the first cutting edge 31 and the third cutting edge 33 at different positions can form a Z-shaped cutting edge with different Z-angles, different upper and lower widths, and different left and right lengths with the second cutting edge 32. The above-mentioned different Z-angles refer to the angles between the first cutting edge 31, the third cutting edge 33 and the second cutting edge 32, so that they can adapt to a variety of Z-shaped blanking dies, avoiding the need to constantly replace a variety of Z-shaped cutting edges to match blanking dies of corresponding shapes, resulting in reduced work efficiency and increased cutting edge costs.

[0040] In this embodiment, a first slide groove 11 is provided on the mold base 1 , the longitudinal section of the mold base 1 is U-shaped, the transverse section of the mold base 1 is H-shaped flipped 90° clockwise or counterclockwise, and the two first sliders 2 are both arranged in the first slide groove 11 .

[0041] Among them, there are two first slide grooves 11, and a stopper is arranged between the two first slide grooves 11. The stopper and the mold base 1 are integrated. The two first sliding blocks 2 are respectively located in the two first slide grooves 11, and the first sliding blocks 2 are in close contact with the inner wall of the first slide groove 11 while ensuring that they can slide, so that the first slide groove 11 has a guiding function to prevent the first sliding block 2 from being skewed when driven by the driving mechanism, resulting in an inability to move. Through the setting of the stopper, the height of the second cutting edge 32 can be easily adapted to the height of the first cutting edge 31 and the third cutting edge 33, and the screw 4 can also be easily installed.

[0042] In some optional embodiments, see Figure 1-4As shown, in the Z-shaped cutting edge adjustment device, a T-shaped second slide groove 22 is provided on the side of the first slider 2 away from the mold base 1, and a second slider 34 that can slide in the second slide groove 22 is provided on the first cutting edge 31 and the third cutting edge 33, and the second slider 34 is adapted to the shape of the second slide groove 22.

[0043] The first cutting edge 31 and the third cutting edge 33 are made to slide in the second slide groove 22 of the first slide block 2 by the second slide groove 22. The T-shaped second slide groove 22 is provided to guide the first cutting edge 31 and the second cutting edge 32 when sliding, so as to prevent the first cutting edge 31 and the third cutting edge 33 from shaking and tilting and changing the horizontal angle when sliding on the first slide block 2, and being unable to form a Z shape with the second cutting edge 32. The T-shaped second slide groove 22 and the second slide block 34 make the connection between the first cutting edge 31, the third cutting edge 33 and the first slide block 2 more secure and prevent them from falling off.

[0044] In some optional embodiments, see Figure 1 and Figure 4 As shown, in the Z-shaped cutting edge adjustment device, a rotating connection assembly is provided between the second cutting edge 32 and the die base 1 .

[0045] In this embodiment, the rotating connection assembly includes a screw 4 disposed on the mold base 1 and a rotating bushing 5 sleeved on an end of the screw 4 away from the mold base 1 .

[0046] In this embodiment, a countersunk hole 321 is formed at the bottom of the second cutting edge 32 , and one end of the screw 4 having the rotating bushing 5 extends into the countersunk hole 321 and is connected.

[0047] By fixing a screw 4 on the die base 1 between the two first sliders 2, a countersunk hole 321 is opened in the direction of the second cutting edge 32 toward the die base 1, and a rotating bushing 5 is rotatably connected in the countersunk hole 321, so that the second cutting edge 32 is pressed down and installed on the screw 4 by the rotating bushing 5, and the rotating bushing 5 and the screw 4 are fixedly connected, the second cutting edge 32 can be rotated on the screw 4 to change the angle.

[0048] In some optional embodiments, see Figure 1-4 As shown, in the Z-shaped cutting edge adjustment device, the driving mechanism includes a motor 12 respectively arranged on both sides of the die base 1 and two threaded rods 13 respectively arranged in the two first sliding blocks 2.

[0049] In this embodiment, a threaded hole 21 is formed on one side of the first sliding block 2 , one end of the threaded rod 13 extends into the threaded hole 21 and is threadedly connected, and the other end of the threaded rod 13 is drivingly connected to the output shaft of the motor 12 .

[0050] In this embodiment, the mold base 1 is arranged on a platform, which is an existing platform for adjusting the horizontal position to change the horizontal position of the cutting edge. No further description is given in this embodiment. The motor 12 is arranged on this platform and is located on both sides of the mold base 1 to cooperate with the two first sliders 2 respectively. The two first sliders 2 are provided with threaded holes 21 on the side facing the motor 12. The threaded holes 21 are threadedly connected with threaded rods 13 or screws. The threaded rod 13 extends out of the threaded hole 21 at one end facing the motor 12 and is transmission-connected with the output shaft of the motor 12, so that the two motors 12 can respectively control the two first sliders 2 to move them to different positions, so that the first cutting edge 31 and the third cutting edge 33 move to different relative positions, forming different Z-shaped cutting edges.

[0051] In some optional embodiments, see Figure 1 and Figure 5 In the Z-shaped blade edge adjustment device, the driving mechanism includes a motor 12 arranged on one side of the mold base 1 and a threaded rod 13 passing through the two first sliders 2.

[0052] In this embodiment, one end of the threaded rod 13 is drivingly connected to the output shaft of the motor 12 , and the threaded rod 13 is provided with two sections of threads that enable the two first sliding blocks 2 to move relative to each other.

[0053] A threaded rod 13 passes through the two first sliders 2, and the threaded rod 13 is provided with two sections of threads, and the rotation directions of the two sections of threads are opposite, so that when the motor 12 drives the threaded rod 13 to rotate, the two first sliders 2 move relative to each other and move closer and further away from each other, so that the first cutting edge 31 and the third cutting edge 33 change positions synchronously to achieve different Z-shaped cutting edges.

[0054] Working principle and process of this application:

[0055] When it is necessary to change the cutting edges of different Z shapes, the motor 12 drives the threaded rod 13 to rotate, and the threaded rod 13 drives the first slider 2 to slide and change its position along the length direction of the mold base 1. The first slider 2 drives the first cutting edge 31 and the third cutting edge 33 to move, so that the first cutting edge 31 and the third cutting edge 33 move on the first slider 2 along the width direction of the mold base 1. When the two first sliders 2 move close to each other, the first cutting edge 31 and the third cutting edge 33 will be squeezed toward the second cutting edge 32. Because the second cutting edge 32 is rotatably connected to the mold base 1, the force applied by the first cutting edge 31 and the third cutting edge 33 to the second cutting edge 32 causes it to rotate on the mold base 1. At the same time, the rotation of the second cutting edge 32 will drive the first cutting edge 31 and the third cutting edge 33 to move on the first slider 2 along the width direction of the mold base 1, and the first cutting edge 31 and the third cutting edge 33 will also be subjected to the reaction force of the second cutting edge 32 when moving synchronously with the first slider 2, and will be squeezed and slid on the first slider 2 to change their position.

[0056] At the same time, the second cutting edge 32 will also be driven to rotate and adapt to and match the first cutting edge 31 and the third cutting edge 33. The first cutting edge 31, the second cutting edge 32 and the third cutting edge 33 are subjected to and transmitted to each other, thereby realizing the linkage among the first cutting edge 31, the second cutting edge 32 and the third cutting edge 33. The first cutting edge 31 and the third cutting edge 33 at different positions can form a Z-shaped cutting edge with different Z-angles, different upper and lower widths, and different left and right lengths with the second cutting edge 32. The above-mentioned different Z-angles refer to the angles between the first cutting edge 31, the third cutting edge 33 and the second cutting edge 32, so that they can adapt to a variety of Z-shaped blanking dies, avoiding the need to constantly replace a variety of Z-shaped cutting edges to match blanking dies of corresponding shapes, resulting in reduced work efficiency and increased cutting edge costs.

[0057] By fixing a screw 4 on the die base 1 between the two first sliders 2, a countersunk hole 321 is opened in the direction of the second cutting edge 32 toward the die base 1, and a rotating bushing 5 is rotatably connected in the countersunk hole 321, so that the second cutting edge 32 is pressed down and installed on the screw 4 by the rotating bushing 5, and the rotating bushing 5 and the screw 4 are fixedly connected, the second cutting edge 32 can be rotated on the screw 4 to change the angle.
