Description

Technical Field

[0001] The utility model relates to the technical field of stamping die positioning, in particular to an auxiliary positioning tooling structure for stamping dies. Background Technique

[0002] The auxiliary positioning tooling structure for stamping dies refers to a device or system used to assist in fixing and positioning workpieces in stamping dies. It can ensure that the workpieces maintain the correct position and posture during the stamping process, thereby avoiding deviation and deformation, and improving the processing accuracy and product quality.

[0003] For example, a positioning mechanism of a stamping part die with the publication number of CN201720354U specifically discloses including an upper die, upper die fastening bolts, a positioning plate, lower die fastening bolts, a lower die mounting base, a lower die flanging cutter block, an upper die pressure plate and an upper die flanging cutter block. A positioning floating driver is connected to the upper die through the upper die fastening bolts. A limit bolt and a guide sleeve are arranged on the lower die mounting base. The limit bolt is rigidly connected to a floating guide column, and a spring is arranged inside the floating guide column.

[0004] During the use of the existing auxiliary positioning tooling structure for stamping dies, the angle of the workpiece cannot be adjusted flexibly. Due to the inability to adjust the angle of the workpiece, there may be a deviation between the actual angle and the designed angle of the workpiece during the stamping process, which will further affect the overall dimensional accuracy and shape accuracy of the product. For stamping parts that require precise angle control, if the positioning tooling cannot adjust the angle flexibly, it may lead to inconsistent angle dimensions of products in the same batch, reducing the product quality. Therefore, we propose an auxiliary positioning tooling structure for stamping dies. Content of the Utility Model

The clamping plate is made of a magnet material, and an electromagnet is installed on the vertical plate.

[0007] A plurality of limiting grooves distributed in a circumferential array are fixedly installed on the annular seat. A plurality of support frames distributed in a circumferential array are fixedly installed on the top of the machine base.

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution for an auxiliary positioning tooling structure of a stamping die:

[0022] An auxiliary positioning tooling structure for a stamping die includes a machine base 1. Vertical columns 2 are fixedly installed at the four corners of the bottom of the machine base 1. A limit hole 3 is opened at the top of the machine base 1. An annular seat 4 is rotatably installed on the top of the machine base 1. A plurality of clamping assemblies are arranged on the annular seat 4 in a circumferential array. The clamping assembly includes a vertical plate 5. The vertical plate 5 is fixedly installed on the annular seat 4. A clamping plate 6 is arranged on one side of the vertical plate 5. Guide rods 7 are fixedly installed at both ends of the clamping plate 6. The guide rods 7 penetrate through the vertical plate 5. Springs 8 are sleeved on the guide rods 7. The two ends of the springs 8 are respectively fixedly connected to the clamping plate 6 and the vertical plate 5. The clamping plate 6 is made of a magnet material. An electromagnet 9 is installed on the vertical plate 5. A plurality of limit grooves 10 are fixedly installed on the annular seat 4 in a circumferential array. A plurality of support frames 11 are fixedly installed on the top of the machine base 1 in a circumferential array. Air cylinders 12 are fixedly installed on the support frames 11. The output ends of the air cylinders 12 are respectively inserted into the limit grooves 10. By placing the workpiece on the annular seat 4 and inserting the lower end of the workpiece into the limit hole 3, it can play a limiting role in the horizontal direction. Then, the elastic force of the spring 8 drives the clamping plate 6 to press against the outside of the workpiece, which can play a positioning role for the workpiece. By rotating the annular seat 4, the workpiece thereon can be driven to rotate synchronously, thereby adjusting the angle of the workpiece.

[0023] Among them, as Figure 3As shown, the inner side of the clamping plate 6 is set as an arc surface, and anti-slip patterns are provided on the inner side of the clamping plate 6. A lower bracket 13 is provided at the lower end of the machine base 1. The lower bracket 13 is fixedly connected to the column 2. An inner block 14 is provided at the upper end of the lower bracket 13. The upper end of the inner block 14 extends into the limit hole 3. An elastic member 15 is fixedly connected to the bottom of the inner block 14. The lower end of the elastic member 15 is fixedly connected to the lower bracket 13. Two spaced-apart stoppers 16 are fixedly installed in the limit hole 3. By placing the workpiece on the annular seat 4 and inserting the lower end of the workpiece into the limit hole 3, it can play a limiting role in the horizontal direction. When the lower end of the workpiece is inserted into the limit hole 3, the air pressure in the limit hole 3 increases and the inner block 14 moves downward, and the elastic member 15 contracts.

[0024] Among them, as Figure 3 and Figure 4 shown, a sealing annular cushion layer is provided in the limit hole 3. An electric push rod 17 is fixedly installed on the lower bracket 13. The upper end of the electric push rod 17 penetrates through the lower bracket 13. The output end of the electric push rod 17 is fixedly installed with a piston 18. The piston 18 penetrates through the inner block 14, and the upper end of the piston 18 extends into the limit hole 3.

[0025] The working principle of the present utility model is as follows: By placing the workpiece on the annular seat 4 and inserting the lower end of the workpiece into the limit hole 3, it can play a limiting role in the horizontal direction. Then, by the elastic force of the spring 8, the clamping plate 6 is driven to press against the outer side of the workpiece, which can play a positioning role for the workpiece. By rotating the annular seat 4, the workpiece thereon can be driven to rotate synchronously, thereby adjusting the angle of the workpiece. Then, by inserting the output ends of the air cylinders 12 into the limit grooves 10 respectively, the angle of the workpiece can be fixed. During the stamping process, if the angle of the workpiece needs to be adjusted, it can be directly adjusted through the tooling structure without stopping the machine to manually adjust the position of the workpiece or replace the tooling, thereby reducing the production interruption time. The adjustable positioning tooling makes the production process more flexible, can adapt to the processing of workpieces with different angle requirements, and improves the adaptability and flexibility of the production line.

[0026] After the lower end of the workpiece is inserted into the limit hole 3, the air pressure in the limit hole 3 increases and the inner block 14 moves downward, and the elastic member 15 contracts. Then, the piston 18 is driven to move downward by the electric push rod 17, and the air pressure in the limit hole 3 decreases, so that the air pressure in the limit hole 3 is in a negative pressure state. Through the air pressure effect, the workpiece is pressed on the annular seat 4, so that the workpiece does not shake up and down during the stamping process.

[0027] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, without special explanation and limitation, are implemented according to the conventional means in the art.
