Description

TECHNICAL FIELD

[0002] The shielding cover is a functional part for electromagnetic shielding, commonly used in the fields of electronics, communications, automobiles, etc., and its main function is to block electromagnetic signal interference through a closed or semi-closed structure of metal material to protect the internal components from working normally.

[0003] However, in the prior art, the uncontrolled feeding amount is manifested as excessive or insufficient material delivery, which directly leads to the deviation of the unfolded length of the stamping part from the design standard. If the feeding amount is excessive, the excess material will accumulate in the mold, causing the upper and lower molds to be stuck during forced stamping, and even causing structural damage to the mold such as mold plate cracking and guide column deformation. If the feeding amount is insufficient, the stretched part will be broken due to insufficient material extension limit, or the rebound angle of the bent part will be abnormal, and the processing deviation will cause the feature positions such as hole positions, bosses, and flanges to deviate from the design reference. For example, in the production of multi-station progressive dies, the deviation causes the internal cavity of the complex structure to be asymmetric, which seriously affects the assembly accuracy and functional matching of the parts with other components.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0017] Embodiment one: refer to Figures 1-7 As shown: a shielding cover automatic stamping forming all-in-one machine, including stamping machine body 1, cutting assembly 2 is installed on one side of stamping machine body 1, and forming assembly 5 is installed on the inner side of stamping machine body 1, and feeding mechanism 3 is installed on one side of stamping machine body 1; Feeding mechanism 3 includes bottom plate 31, two side plates 32 are fixedly connected to the top of bottom plate 31 in a symmetrical manner, two support plates 321 are fixedly connected to the top of side plate 32 in a symmetrical manner, a movable frame 36 is arranged between the two support plates 321, a limiting groove 362 is formed in the bottom of movable frame 36, a second limiting block 363 is slidably connected to the inner side of limiting groove 362, one end of second limiting block 363 is fixedly connected to the side wall of side plate 32, a rotating shaft 391 is rotatably connected to the top end of side plate 32, a deflection wheel 39 is fixedly connected to one end of rotating shaft 391, and the deflection wheel 39 is clamped with movable frame 36.

[0018] The top of bottom plate 31 is fixedly connected with a support frame 33, a sliding rod 34 is slidably connected to the inner side of one end of support frame 33, a first limiting block 341 is fixedly connected to the bottom end of sliding rod 34, and an arc-shaped pressing block 342 is fixedly connected to the bottom end of first limiting block 341.

[0019] In this embodiment, during the processing and production of the shielding cover, the workpiece is conveyed by the feeding mechanism 3. The main function of the feeding mechanism 3 is to accurately and stably feed the workpiece to the working position of the stamping machine body 1, so as to ensure the smooth progress of the stamping process. During the conveying process, first, the workpiece will be extruded by the arc-shaped pressing block 342. Ensure that the stamping machine body 1 can accurately position the workpiece during stamping, so as to avoid the situation that the workpiece slips or the stamping is unqualified due to inaccurate positioning.

[0020] In addition, during the conveying process of feeding mechanism 3. The rotation of rotating shaft 391 not only drives the deflection wheel 39 to rotate together, but also exerts a certain force on movable frame 36 during the rotation of deflection wheel 39, which pushes movable frame 36 to move along the guide rail. Not only limited to linear motion, the motion trajectory of movable frame 36 is also limited by limiting groove 362 and second limiting block 363, which ensures that movable frame 36 can move along the predetermined trajectory during the movement.

[0021] With the movement of movable frame 36, feeding tooth plate 361 also moves with it. Since the center of rotation of deflection wheel 39 is rotating shaft 391, during the movement of movable frame 36, not only will there be an up-and-down movement, but also will cause feeding tooth plate 361 to move horizontally. When feeding tooth plate 361 reaches the bottom of the workpiece, the contact between feeding tooth plate 361 and the workpiece will exert a force on the workpiece. This force will push the workpiece to move in the conveying direction, thereby realizing the accurate conveying of the workpiece.

[0022] Since the movement of the feeding tooth plate 361 is precisely controlled, it can effectively control the distance of each workpiece movement. This precise movement control not only ensures the accuracy of each feeding and avoids errors, but also effectively reduces material waste. The high accuracy in each feeding process can avoid the extension of production cycle or the decline of product quality caused by inaccurate feeding. In addition, precise feeding also makes the subsequent stamping and processing process more smooth, ultimately improving production efficiency and workpiece qualification rate.

[0023] Efficient and accurate workpiece conveying is achieved. Not only the stability and accuracy of the production process are guaranteed, but also the waste in production is greatly reduced, and the overall production efficiency is improved.

[0024] Embodiment two: Figures 2-5 As shown, a spring 35 is arranged between the support frame 33 and the first limiting block 341, the spring 35 is sleeved on the outer surface of the sliding rod 34, and the top of the movable frame 36 is fixedly connected with the feeding tooth plate 361. A driving motor 4 is installed on one side of the top of the bottom plate 31, and the output end of the driving motor 4 is fixedly connected with a rotating rod 37. The rotating rod 37 penetrates through the two side plates 32 respectively, and the rotating rod 37 is rotatably connected with the side plates 32. The outer surfaces of both ends of the rotating rod 37 are fixedly connected with a belt synchronous assembly 38, and one end of the belt synchronous assembly 38 is fixedly connected with the outer surface of the rotating shaft 391.

[0025] In this embodiment, during the entire processing process, the operation of the driving motor 4 provides a power source, so that the rotating rod 37 can rotate. When the rotating rod 37 starts to rotate, its rotating action will be effectively transmitted to the two belt synchronous assemblies 38. The synchronous rotation of these belt synchronous assemblies 38 makes the rotating shaft 391 also rotate. The rotating shaft 391 can realize effective feeding of the workpiece through the shaft body activity.

[0026] In the process of positioning the workpiece, the spring 35 is used to push the first limiting block 341 to move downward. The elastic effect of the spring 35 ensures that the pressure during positioning is uniform, avoiding excessive impact on the workpiece. When the first limiting block 341 moves downward, it will directly drive the arc-shaped pressing block 342 to generate a certain extrusion force on the workpiece. The arc-shaped pressing block 342 has good adaptability and can be adjusted according to the shape and requirements of the workpiece to ensure accurate positioning of the workpiece and not affected by external forces.

[0027] In addition, the sliding connection between the sliding rod 34 and the support frame 33 is designed. The sliding rod 34 allows the arc-shaped pressing block 342 and the first limiting block 341 to have certain movement space in the up-down direction. Not only ensures that the workpiece will not be too constrained when positioning, but also ensures that when the workpiece needs to move forward or backward, it will not interfere with the feeding process. The arc-shaped pressing block 342 and the first limiting block 341 can maintain a relatively independent motion state, effectively avoiding the influence on the workpiece during feeding, thereby improving the working efficiency and precision of the entire system.

[0028] In summary, the cooperative action of the driving motor 4, the rotating rod 37, the belt synchronous assembly 38, the rotating shaft 391, and the spring 35, the first limiting block 341 and other components makes the feeding and positioning in the entire processing process more accurate and efficient. Ensure the stable operation of the equipment under high load, and minimize errors to improve the overall performance of the production line.

[0029] Embodiment three: according to Figure 6 As shown in the figure, the cutting assembly 2 includes a fixed plate 21, which is fixedly connected with the side wall of the punch machine body 1, and two air cylinders 22 are symmetrically installed on the top of the fixed plate 21, and the output end of the air cylinder 22 is fixedly connected with a cutting knife 23. The forming assembly 5 includes a mold 52, both sides of which are provided with a base 51, and the base 51 is installed on the inner side of the punch machine body 1, and the base 51 is clamped with two positioning blocks 53 on one side. The positioning block 53 is provided with a positioning hole 55 on the surface, and a screw rod 54 is inserted into the inner side of the positioning hole 55, and the bottom end of the screw rod 54 is threadedly connected with the punch machine body 1.

[0030] In this embodiment, after the stamping forming process, the downward movement of the cutting knife 23 can be accurately controlled by the driving of the air cylinder 22. The cutting knife 23 can effectively cut the workpiece during the pressing process, and can quickly remove the excess waste, improve the production efficiency, and ensure the accuracy of the product.

[0031] In the process of stamping forming, the punch machine body 1 plays an important role. Its structure design makes it possible to process different types and specifications of shielding covers by selecting the mold 52. The mold 52 is stably supported and limited by the two bases 51, which can effectively ensure the stability and positioning accuracy of the mold 52 during work. The constraint force between the bases 51 makes the mold 52 not displace or deform during the stamping process, thereby ensuring that each processing can reach the same high quality standard.

[0032] In addition, the screw rod 54 plays an important role in extruding and positioning the base 51 on the side wall. Not only can it fix the base 51 in the desired position, but also can further enhance the stability of the mold 52 by adjusting the length and angle of its threaded part. Through precise positioning, the screw rod 54 ensures the precise fit of the mold 52 and the base 51, thereby reducing errors during processing.

[0033] To further enhance the flexibility and convenience of the processing process, the design of the positioning block 53 and the positioning hole 55 provides great convenience for the replacement and maintenance of the mold 52. The screw rod 54 passes through the positioning hole 55 and is connected with the punch body 1, which can accurately fix the positioning block 53 and prevent any loosening during processing. At the same time, the structural design of the positioning block 53 makes the replacement of the mold 52 more efficient, and the operator only needs to simply disassemble the screw rod 54 to replace different types of molds 52 to adapt to different batches or different specifications of the shield cover production requirements.

[0034] The working principle and method of using the device: during the processing and production of the shield cover, the workpiece is conveyed by the feeding mechanism 3. During conveying, the arc-shaped pressing block 342 first extrudes the workpiece to provide positioning for the punching process of the punch body 1, preventing the workpiece from sliding.

[0035] The power transmission of the feeding mechanism 3 is realized through the rotating shaft 391. When the rotating shaft 391 rotates, it drives the deflection wheel 39 to rotate synchronously. During rotation, the deflection wheel 39 continuously applies force to the movable frame 36. Since the movable frame 36 is limited by the second limiting block 363, the movable frame 36 not only drives the feeding tooth plate 361 when moving, but also produces a composite motion of up and down and transverse. When the feeding tooth plate 361 contacts the bottom of the workpiece, the pushing force generated by this composite motion will push the workpiece forward. By controlling the rotation of the rotating shaft 391, the moving distance of the workpiece can be accurately adjusted to ensure the feeding accuracy and reduce material waste.

[0036] During processing, the driving motor 4 rotates the rotating rod 37, which transmits power to the two belt synchronous assemblies 38, thereby driving the rotating shaft 391 to rotate and starting the feeding process.

[0037] The workpiece positioning relies on the elasticity of the spring 35. The spring 35 pushes the first limiting block 341 downward, driving the arc-shaped pressing block 342 to extrude the workpiece. Since the sliding rod 34 and the support frame 33 are connected by sliding, the arc-shaped pressing block 342 and the first limiting block 341 can move up and down flexibly, without affecting the workpiece positioning or hindering the feeding process.

[0038] In the stamping process, the cylinder 22 moves downward by driving the cutting knife 23 to realize the cutting operation of the workpiece. Ensure the integrity of the shield cover forming, while removing the excess waste. Specifically, the cylinder 22 controls the pressure and speed of the driving device accurately, so that the cutting knife 23 cuts into the workpiece with appropriate force and speed, thereby avoiding deformation or damage of the workpiece due to excessive impact. The cutting edge of the cutting knife 23 is usually very sharp, which can effectively cut metal or other materials and complete the cutting task in a short time. In addition, the cylinder 22 can also adjust the pressure and moving speed according to the material properties and thickness of different workpieces, to ensure the stability and efficiency of the cutting process. Through such fine control, not only the required shield cover forming part can be obtained, but also the waste in the production process can be minimized, the production efficiency can be improved, and the material loss can be reduced.

[0039] In the processing link of the punch main body 1, different types of shield covers can be produced by replacing the mold 52. The mold 52 is limited by two bases 51, and the screw rod 54 extrudes the side wall of the base 51 to realize preliminary fixation. The screw rod 54 is connected with the punch main body 1 through the positioning hole 55, which not only can stabilize the positioning block 53, but also is convenient for disassembly, so that the mold 52 is more convenient to replace, meets the production needs of different batches of shield covers, and is also convenient for equipment maintenance.

[0040] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
