Description

Technical Field

[0001] This utility model relates to the technical field of high-precision sheet metal stamping positioning devices, and in particular to a high-precision sheet metal stamping positioning device. Background Technology

[0002] Sheet metal parts can be transformed from flat materials into various complex three-dimensional shapes through stamping. For example, many of the outer shell components of a car body are formed by stamping metal sheets to create streamlined body contours, including doors, hoods, and trunk lids. These shapes would be difficult to achieve with such precision and complexity using other processing methods.

[0003] A well-designed stamping shape can enhance the structural strength of sheet metal parts. For example, in some load-bearing sheet metal parts, stamping out reinforcing ribs can significantly improve the bending and compressive strength of the parts without increasing the material thickness. For instance, in the side panels of a machine housing, stamped reinforcing ribs can effectively prevent deformation of the side panels under external forces.

[0004] Currently, the methods used to achieve stamping positioning of sheet metal parts include: (1) setting positioning pins on the mold, and positioning is achieved by cooperating with the positioning pins through the external holes of the sheet metal parts or the pre-machined process holes. For example, when processing sheet metal parts with mounting holes, the positioning pins on the mold are inserted into these mounting holes, which can accurately determine the position of the sheet metal parts in the mold. This positioning method has high accuracy and is suitable for stamping processing with strict positional accuracy requirements; (2) using the edge contour of the sheet metal parts to fit and position the positioning edge of the mold. For example, for rectangular sheet metal parts with regular shapes, the mold has corresponding right-angled edges to position the edges of the sheet metal parts, ensuring that the sheet metal parts will not shift during the stamping process. This method is simple and direct and is more suitable for some sheet metal parts with less complex shapes and less stringent dimensional accuracy requirements.

[0005] However, the existing positioning devices have low support stability for stamping dies, and cannot effectively guarantee the stability and reliability of stamping processes during long-term stamping operations. Utility Model Content

[0006] In view of this, the technical problem to be solved by this utility model is: how to provide a high-precision sheet metal stamping positioning device to improve the support stability of the stamping positioning device.

[0007] To achieve the above objectives, this utility model proposes a high-precision sheet metal stamping positioning device, which includes a base, a positioning seat, a stamping seat, a stud, a compression spring, a positioning nut, a sleeve, an adjusting screw, and a support plate.

[0008] The stud is connected to both sides of the base and is arranged vertically. The positioning nut is connected to the stud and the positioning seat is sleeved on the stud and supported by the positioning nut. The position of the positioning seat in the height direction of the stud is adjusted by the connection position of the positioning nut on the stud.

[0009] The compression spring and the stamping seat are respectively sleeved on the stud. The stamping seat is located above the positioning seat, and the compression spring is located between the stamping seat and the positioning seat, supporting the stamping seat.

[0010] The sleeve is connected to the base by fasteners. The sleeve is located in the middle of the base. The inside of the sleeve is hollow. The adjusting screw is threaded to the hollow part of the sleeve. The adjusting screw is threaded to the support plate at the end facing the positioning seat. The top surface of the support plate is flat and fits against the bottom surface of the positioning seat.

[0011] Furthermore, the adjusting screw is threadedly connected to the sleeve to adjust the connection position of the adjusting screw with the sleeve in the height direction.

[0012] Furthermore, a screw cap is provided in the middle of the support plate, and the end of the adjusting screw is connected to the screw cap. The support plate is made of rubber.

[0013] Furthermore, the top surface of the positioning nut and the top surface of the support plate are located on the same horizontal plane and together support the bottom surface of the positioning seat.

[0014] Compared with related technologies, the high-precision sheet metal stamping positioning device proposed in this utility model has the following advantages: the top surface of the support plate is flat and fits closely to the bottom surface of the positioning seat, which increases the contact area. When supporting the positioning seat, it can more evenly distribute the pressure on the positioning seat, preventing excessive local pressure from causing the positioning seat to tilt or shake, effectively improving the support stability of the positioning seat. The positioning nut can adjust the position of the positioning seat in the height direction of the stud, and cooperates with the support plate to position the positioning seat from both the top and bottom directions. The positioning nut determines the height position of the positioning seat, while the support plate provides stable planar support at the bottom. The combined effect of the two makes the position of the positioning seat more accurate and stable in the vertical direction. Therefore, even if subjected to pressure and vibration from the stamping seat during the stamping process, the positioning seat can maintain a stable position, ensuring the accuracy of high-precision sheet metal stamping positioning.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Please see Figure 1-2 As shown, this utility model proposes a high-precision sheet metal stamping positioning device, which includes a base 11, a positioning seat 12, a stamping seat 13, a stud 14, a compression spring 15, a positioning nut 16, a sleeve 21, an adjusting screw 22, and a support plate 23.

[0019] Stud 14 is connected to both sides of base 11. Stud 14 is set in a vertical direction. Positioning nut 16 is connected to stud 14. Positioning seat 12 is sleeved on stud 14 and supported on positioning nut 16. The position of positioning seat 12 in the height direction of stud 14 is adjusted by the connection position of positioning nut 16 on stud 14.

[0020] The compression spring 15 and the stamping seat 13 are respectively sleeved on the stud 14. The stamping seat 13 is located above the positioning seat 12, and the compression spring 15 is located between the stamping seat 13 and the positioning seat 12, supporting the stamping seat 13.

[0021] The sleeve 21 is connected to the base 11 by fasteners. The sleeve 21 is located in the middle of the base 11. The inside of the sleeve 21 is hollow. The adjusting screw 22 is connected to the hollow part of the sleeve 21 by threads. The adjusting screw 22 is connected to the sleeve 21 by threads to adjust the connection position of the adjusting screw 22 with the sleeve 21 in the height direction.

[0022] The adjusting screw 22 is threaded to the end of the positioning seat 12 and connected to the support plate 23. The top surface of the support plate 23 is flat and fits against the bottom surface of the positioning seat 12.

[0023] A screw cap is provided in the middle of the support plate 23, and the end of the adjusting screw 22 is connected to the screw cap. The support plate 23 is made of rubber.

[0024] The top surface of the positioning nut 16 and the top surface of the support plate 23 are on the same horizontal plane and together support the bottom surface of the positioning seat 12.

[0025] The top surface of the support plate 23 is flat and fits snugly against the bottom surface of the positioning seat 12. This close fit design increases the contact area. When supporting the positioning seat 12, it can distribute the pressure on the positioning seat 12 more evenly, preventing excessive local pressure from causing the positioning seat 12 to tilt or wobble, and effectively improving the support stability of the positioning seat 12.

[0026] The positioning nut 16 can adjust the position of the positioning seat 12 in the height direction of the stud 14, and cooperate with the support plate 23 to position the positioning seat 12 from both the top and bottom directions.

[0027] The top surface of the support plate 23 is flat and can fit tightly against the bottom surface of the positioning seat 12. During the operation of the entire device, the positioning seat 12 bears the pressure of the stamping seat 13. Through the large-area contact, the pressure is evenly distributed on the support plate 23, preventing the positioning seat 12 from tilting or shifting due to uneven force, and providing stable and reliable bottom support for the positioning seat 12.

[0028] The positioning nut 16 determines the height position of the positioning seat 12, while the support plate 23 provides stable planar support at the bottom. The two work together to make the positioning seat 12 more accurate and stable in the vertical direction. Thus, even if it is subjected to pressure and vibration from the stamping seat 13 during the stamping process, the positioning seat 12 can maintain a stable position, ensuring the accuracy of high-precision sheet metal stamping positioning.

[0029] The adjusting screw 22 is threadedly connected to the sleeve 21 and also threadedly connected to the support plate 23. By rotating the adjusting screw 22, the height of the support plate 23 can be precisely adjusted. This allows for fine-tuning of the position of the support plate 23 according to actual needs during installation or debugging, thereby ensuring the levelness of the positioning seat 12 and ensuring that the positioning seat 12 remains horizontal and stable during stamping, which is beneficial to improving the accuracy of sheet metal stamping positioning.

[0030] In conjunction with the positioning nut 16, the positioning seat 12 is limited from both the top and bottom directions. In the vertical direction, the positioning nut 16 determines the approximate position of the positioning seat 12, while the support plate 23, as the bottom support and fine-tuning component, works in synergy with the positioning nut 16 to make the vertical position of the positioning seat 12 more accurate and stable, thereby enhancing the anti-interference capability of the positioning seat 12 during the stamping process.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
