Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a material stripping core elastic force regulating mechanism, and also to a blanking, punching and inverted composite die applying the material stripping core elastic force regulating mechanism. Background Art

[0002] In the existing inverted composite mold, the punching waste can easily leak out of the hole of the press table. The workpiece is pushed into the material belt through the upper mold, and then the workpiece is brought out by the material belt. This operation method is convenient and safe, and can ensure high productivity. However, when stamping and producing composite materials such as silencers, since these materials are generally composed of nitrile rubber, steel plates, cold adhesive, release paper, etc., during the stamping process, the cold adhesive will slowly enter the gap between the concave mold plate and the stripping core. The glue has a strong viscosity, which makes it impossible for the workpiece to be ejected smoothly in the concave mold. The traditional solution is to replace the high-strength spring, but this method is cumbersome and costly.

[0003] Based on the above problems existing in the prior art, designing a spring force adjustment mechanism for a material stripping core that is simple to operate and convenient for adjusting the spring force of the material stripping core becomes a problem to be solved by the present application. Utility Model Content

[0004] One aspect of the utility model is to provide a material-removing core elastic force adjustment mechanism, which solves the problem of increased spring force demand caused by glue penetration during the production process through a simple adjustment method, thereby improving production efficiency and reducing production costs.

[0005] In order to solve the above technical problems, the present application provides a material-removing core elastic force adjustment mechanism, comprising:

[0006] A fixed plate, with inclined mounting surfaces provided at both ends;

[0007] The elastic material-removing mechanism is arranged at both ends of the fixed plate; it includes an elastic component and a mounting component for mounting the elastic component;

[0008] The elastic component is used to provide the required elastic force during the material withdrawal process and assist the material withdrawal core to complete the material withdrawal action;

[0009] The wedge-shaped slider mechanism is located between the fixed plate and the elastic material stripping mechanism and is movably mounted on the inclined mounting surfaces at both ends of the fixed plate. The elastic force of the elastic material stripping mechanism can be adjusted by sliding up and down along the mounting surfaces.

[0010] By adopting the above technical solution, the wedge-shaped slider assembly cooperates with the inclined mounting surfaces set at both ends of the fixed plate, realizing the adaptive adjustment of the elastic force of the elastic assembly in the elastic material-removing mechanism, which can meet more types of material-removing needs and realize efficient material-removing. With the above design, the elastic force adjustment flexibility of the elastic assembly is stronger, the adjustment range is wider, and the adjustment is more convenient.

[0011] In addition to the above-mentioned technical features, this application also makes improvements in the following aspects:

[0012] In some embodiments, the wedge-shaped slider mechanism includes a wedge-shaped slider and a slider adjustment mechanism, wherein the slider adjustment mechanism includes a screw rod and an adjustment nut, and the slider adjustment mechanism is used to adjust the movement position of the wedge-shaped slider.

[0013] By adopting the above technical solution, the slider adjustment mechanism allows the operator to easily and accurately control and adjust the moving position of the wedge-shaped slider, thereby changing the elastic force of the elastic component. The above design simplifies the elastic force adjustment process, is convenient to operate, and reduces the time and labor cost required for adjustment.

[0014] In some embodiments, the wedge-shaped slider is in the shape of a right triangle, with two right-angled surfaces and an inclined surface, one of the right-angled surfaces is provided with a longitudinal long hole, and the other right-angled surface is provided with a transverse through hole, through which the screw of the slider adjustment mechanism passes, one end of the screw is threadedly connected to the threaded hole provided on the fixing plate, and the other end is threadedly connected to the adjusting nut. The position of the wedge-shaped slider relative to the inclined mounting surface can be changed by adjusting the adjusting nut.

[0015] By adopting the above technical solution: longitudinal long holes and transverse through holes are respectively provided between the two right-angled surfaces and the inclined surface of the wedge-shaped slider, and the position of the wedge-shaped slider relative to the inclined mounting surface can be conveniently adjusted by using a screw rod and an adjusting nut. This design makes the adjustment of the spring force more flexible and convenient. In addition, the design of the adjusting nut makes it simple to adjust the position of the wedge-shaped slider. The operator only needs to rotate the adjusting nut to adjust the position of the wedge-shaped slider, which makes the adjustment more convenient.

[0016] In some embodiments, the elastic components are arranged in multiple groups and distributed at both ends of the fixing plate.

[0017] By adopting the above technical solution: the provision of multiple groups of elastic components means that a greater elastic force can be provided during the material withdrawal process, thereby more effectively assisting the material withdrawal core to complete the material withdrawal action.

[0018] In some embodiments, the elastic component is sleeved on the mounting component, and one end of the mounting component passes through a long hole provided on the upper part of the wedge-shaped slider and is fixed on the fixing plate.

[0019] By adopting the above technical solution, the effective transmission of elastic force is ensured. When the material stripping core performs the material stripping action, the elastic component can evenly transmit the elastic force to the wedge-shaped slider through the mounting component, thereby achieving a smooth and reliable material stripping process. Among them, the design of the long hole provides a range of motion for the movement of the wedge-shaped slider, and the elastic force adjustment range is larger, and the applicability is stronger.

[0020] In some embodiments, a gasket is provided at the contact position between the elastic component and the wedge-shaped slider, and the gasket is an annular gasket, and the gasket is sleeved on the mounting component.

[0021] By adopting the above technical solution, the gasket is located between the elastic component and the wedge-shaped slider, which plays a buffering role, reduces the direct contact and friction between the two, and reduces wear. At the same time, it also protects the elastic component from direct impact by the wedge-shaped slider, avoids damage to the elastic component due to excessive force, and prolongs the service life of the elastic component and the wedge-shaped slider.

[0022] In some embodiments, the elastic component includes four groups of coil springs, which are arranged in pairs and symmetrically mounted at both ends of the fixing plate.

[0023] By adopting the above technical solution, four sets of spiral springs are installed symmetrically to ensure that the elastic force is evenly distributed at both ends of the fixed plate. The above design helps to maintain the stability of the material removal core during the material removal process and prevent material removal deviation or jamming caused by uneven elastic force.

[0024] In some embodiments, the four groups of coil springs are all rectangular coil springs.

[0025] By adopting the above technical solution, the cross section of the rectangular coil spring is rectangular, and compared with the spring with a circular cross section, it has higher stiffness and greater load-bearing capacity under the same space conditions. During the material removal process, the rectangular coil spring can provide a more stable support force, ensuring the stability and reliability of the material removal process.

[0026] In some embodiments, the mounting assembly includes four groups of equal-height sleeves, which are symmetrically distributed in groups of two on wedge-shaped sliders arranged at both ends of the fixed plate, and each group of equal-height sleeves is correspondingly installed with a group of coil springs.

[0027] By adopting the above technical solution, the symmetrical distribution of the four groups of equal height sleeves can ensure the stability and balance of the coil springs during the material removal process, which is convenient for rapid material removal. In addition, each group of equal height sleeves is installed with a group of coil springs. This one-to-one correspondence ensures the effective transmission and precise control of the elastic force. When the wedge-shaped slider moves, the coil springs can evenly apply or release the elastic force through the guidance of the equal height sleeves, thereby realizing the smooth material removal of the material removal core.

[0028] Another aspect of the utility model is to provide a blanking, punching and inverted composite die, which is provided with the above-mentioned material-removing core elastic force adjustment mechanism.

[0029] By adopting the above technical solution, the blanking, punching and flipping composite die introduces a core-retracting elastic force adjustment mechanism, which functionally optimizes the performance of the die, reduces die sticking and sticking phenomena, reduces the maintenance cost of the die, and extends the service life of the die.

[0030] In summary, the utility model has the following beneficial effects:

[0031] 1. This application realizes adaptive adjustment of the elastic force of the elastic component through the cooperation of the wedge-shaped slider mechanism and the inclined mounting surface of the fixed plate and the combined design of the slider adjustment mechanism, making the material withdrawal process more efficient.

[0032] 2. This application can adapt to different material return requirements and provide adaptive elastic force to assist the material return core in completing the material return action.

[0033] 3. The present application adopts a screw and an adjusting nut combination structure to directly adjust the elastic force of the elastic component, which simplifies the elastic force adjustment process, improves the convenience of operation, and reduces adjustment time and labor costs.

[0034] 4. This application applies the core-retracting elastic force adjustment mechanism to the blanking, punching and flip-chip composite mold, which optimizes the performance of the mold, reduces the occurrence of problems such as mold jamming and sticking during the production process, and improves production efficiency.

The present application can be implemented in other different forms and is not limited to the embodiments described herein.

[0043] 1. Explanation of Descriptive Terms in This Application

[0044] The embodiments provided in this application in conjunction with the technical solutions are intended to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art. It should be noted that unless otherwise specifically stated in this application, the relative arrangement of components described in these embodiments should be interpreted as merely exemplary, and not as a limitation to the technical solutions of this application.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly. These or other directional terms should not be understood as restrictive terms.

[0046] In the present application, when a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other device without an intermediate device, or may not be directly connected to the other device but have an intermediate device.

[0047] In addition, this application does not discuss in detail the technologies and equipment known to ordinary technicians in the relevant fields, but where appropriate, the technologies and equipment should be considered as part of the specification.

[0048] The application scenarios of the present application are mainly based on the flip-chip composite mold, and can also be applied to other scenarios according to its functions. Its application scenarios are not restricted or limited by the specific embodiments described in this application.

[0049] Second, when processing composite materials such as mufflers and other composite materials based on traditional inverted composite molds, it is often encountered that the cold adhesive in the material penetrates into the mold gap, making it difficult to eject the workpiece, and the existing ejection core spring force cannot be adjusted and is inconvenient to replace. This application specifically provides a technical solution to the above problems. The technical solution, working principle and technical effect of this application are described in detail below in conjunction with specific embodiments.

[0050] The utility model records a material-removing core elastic force regulating mechanism, which is used for regulating the spring force of the material-removing core.

[0051] like Figure 1 , Figure 2 As shown, this embodiment provides a stripping core elastic force adjustment mechanism, which includes a fixed plate 1, an elastic stripping mechanism and a wedge-shaped slider mechanism.

[0052] Both ends of the fixing plate 1 are provided with inclined mounting surfaces 11. The design of the inclined mounting surfaces at both ends of the fixing plate enables the wedge-shaped slider mechanism to slide stably thereon, thus ensuring the stability and reliability of the adjustment process.

[0053] The elastic material-removing mechanism is arranged at both ends of the fixed plate 1, and includes an elastic component 2 and a mounting component 3 for mounting the elastic component 2. The elastic component 2 is used to provide the required elastic force during the material-removing process, which helps to assist the material-removing core to quickly and accurately complete the material-removing action. The design of the elastic material-removing mechanism can improve the material-removing efficiency, reduce the jamming and delays in the material-removing process, and facilitate the realization of rapid material-removing.

[0054] The wedge-shaped slider mechanism is located between the fixed plate 1 and the elastic material stripping mechanism, and is movably mounted on the inclined mounting surfaces 11 at both ends of the fixed plate 1 .

[0055] The mechanism can adjust the elastic force of the elastic material stripping mechanism by sliding up and down along the mounting surface 11. This design enables the mechanism to adapt to different material stripping requirements, provide appropriate elastic force to assist the material stripping core to complete the material stripping action, thereby enhancing the flexibility and applicability of the mechanism.

[0056] The overall design of the mechanism is simple, which is convenient for daily maintenance and upkeep. The modular design of the elastic components and mounting components enables quick replacement or repair, which reduces downtime and improves the efficiency of equipment use.

[0057] Specifically, the wedge-shaped slider mechanism includes a wedge-shaped slider 4 and a slider adjustment mechanism, wherein the slider adjustment mechanism includes a screw rod 5 and an adjustment nut 6.

[0058] The slider adjustment mechanism can accurately adjust the moving position of the wedge-shaped slider 4. This precision adjustment can meet the elastic force setting under different process requirements and ensure the stability and accuracy during the material withdrawal process.

[0059] During operation, when the elastic force needs to be adjusted, the operator can easily adjust the position of the wedge-shaped slider through the slider adjustment mechanism, thereby changing the elastic force of the elastic material removal mechanism. Specifically, a handle, gear or other components can be used for driving, so that the operator can easily and accurately control and adjust the moving position of the wedge-shaped slider.

[0060] Based on the above slider adjustment mechanism setting, the wedge-shaped slider mechanism can adapt to more types of material return requirements. Whether in different materials, different processes or different production environments, the ideal elastic effect can be achieved by adjusting the position of the wedge-shaped slider.

[0061] In the actual working process, when it is necessary to change products or adjust processes, the elastic force can be quickly adjusted through the slider adjustment mechanism to adapt to the new production process requirements. This design simplifies the adjustment process, improves the convenience of operation, and reduces the time and labor costs required for adjustment.

[0062] In addition, the reasonable elastic force setting of the slider adjustment mechanism can also reduce the impact and vibration during the material return process, thereby protecting the equipment and improving product quality.

[0063] As a preference, Figure 3 , Figure 4 As shown, in this embodiment, the wedge-shaped slider 4 is in the shape of a right triangle, with two right-angled surfaces and an inclined surface. A longitudinal long hole 41 is provided on one right-angled surface, and a transverse through hole 42 is provided on the other right-angled surface. The screw 5 of the slider adjustment mechanism passes through the transverse through hole, one end of the screw 5 is threadedly connected to the threaded hole provided on the fixing plate 1, and the other end is threadedly connected to the adjusting nut 6. By adjusting the adjusting nut 6, the position of the wedge-shaped slider 4 relative to the inclined mounting surface 11 can be changed.

[0064] The wedge-shaped slider adopts a right-angled triangle shape design, which enables the wedge-shaped slider to adapt to the inclined installation surface, and its structural characteristics also make it easy to connect with other components. This design increases the versatility and applicability of the slider.

[0065] A longitudinal long hole and a transverse through hole are respectively provided between the two right-angled surfaces and the inclined surface of the wedge-shaped slider. With the use of a screw and an adjusting nut, the position of the wedge-shaped slider relative to the inclined mounting surface can be easily adjusted. This design makes the adjustment of the spring force more flexible and convenient. When the adjusting nut is tightened inward, the wedge-shaped slider is squeezed. Under the action of the adjusting nut, the wedge-shaped slider moves upward to squeeze the elastic component, and the spring force increases. Conversely, the adjusting nut is adjusted in the opposite direction, the wedge-shaped slider moves downward, and the spring force decreases.

[0066] In addition, the design of the adjusting nut makes it easy to adjust the position of the wedge-shaped slider. The operator only needs to rotate the adjusting nut to adjust the position of the wedge-shaped slider, which makes the adjustment more convenient.

[0067] The elastic components 2 are arranged in multiple groups and distributed at both ends of the fixing plate 1 .

[0068] In this embodiment, as a preference, the elastic component 2 includes four groups of coil springs, which are arranged in pairs and symmetrically mounted at both ends of the fixing plate 1. The four groups of coil springs are all rectangular coil springs to provide higher stiffness and greater load-bearing capacity.

[0069] Symmetrical installation of four sets of coil springs can ensure that the elastic force is evenly distributed at both ends of the fixed plate, while reducing the mechanical wear between the stripping core and the fixed plate.

[0070] The above design also helps to maintain the stability of the material removal core during the material removal process and prevent material removal deviation or jamming caused by uneven elastic force.

[0071] The symmetrical installation of four sets of coil springs can ensure uniform distribution of elastic force, so that the stripping core can complete the stripping action in a shorter time, thereby improving the stripping efficiency. At the same time, it can also resist external vibration and impact, ensuring that the stripping core can still maintain stable operation in a complex working environment.

[0072] In summary, the symmetrical installation of four sets of coil springs can achieve uniform distribution of elastic force, improve stripping efficiency, reduce mechanical wear, and enhance structural stability. These effects together provide guarantees for the performance and reliability of the stripping core elastic force adjustment mechanism.

[0073] As a preference, all four groups of coil springs are rectangular coil springs, which have higher stiffness and greater load-bearing capacity than coil springs with circular cross-sections under the same space conditions. During the material removal process, the rectangular coil spring can provide more stable support force and stronger restoring force, ensuring the accuracy and efficiency of the material removal action.

[0074] In addition, the rectangular coil spring is suitable for high-load occasions. In the stripping core elastic force adjustment mechanism, this spring can adapt to various complex working environments and further ensure the stability and reliability of the stripping process.

[0075] Preferably, the mounting assembly 3 includes four groups of equal-height sleeves, which are symmetrically distributed in groups of two on the wedge-shaped sliders 4 arranged at both ends of the fixing plate 1. Each group of equal-height sleeves is correspondingly installed with a group of spiral springs.

[0076] The mounting assembly uses four sets of symmetrically distributed equal-height sleeves to ensure the stability and balance of the spiral spring during the material removal process, facilitating rapid material removal.

[0077] In addition, each set of equal height sleeves is installed with a corresponding set of coil springs. This one-to-one correspondence ensures the effective transmission and precise control of the elastic force.

[0078] When the wedge-shaped slider moves, the spiral spring evenly applies or releases elastic force along the equal height sleeve, thereby realizing smooth material removal of the material removal core.

[0079] As an optimized design, the elastic component 2 is sleeved on the mounting component 3, and one end of the mounting component 3 passes through the long hole 41 provided on the upper part of the wedge-shaped slider 4 and is fixed on the fixed plate 1. When the stripping core performs the stripping action, the elastic component can evenly transfer the elastic force to the wedge-shaped slider through the mounting component, thereby realizing a smooth and reliable stripping process.

[0080] Among them, the design of the long hole provides a range for the movement of the wedge-shaped slider, the elastic force adjustment range is larger, and the applicability is stronger.

[0081] As a further optimization scheme, a gasket 7 is provided at the contact position between the elastic component 2 and the wedge-shaped slider 4. The gasket 7 is an annular gasket, which is sleeved on the mounting component 3 and located between the elastic component and the wedge-shaped slider, playing a buffering and protective role, which can reduce direct contact and friction between the two and reduce wear. At the same time, it also protects the elastic component from direct impact of the wedge-shaped slider, avoids damage to the elastic component due to excessive force, and prolongs the service life of the elastic component and the wedge-shaped slider.

[0082] This embodiment also provides a blanking, punching and flipping compound die, which is equipped with the above-mentioned material removal core elastic force adjustment mechanism. By introducing the material removal core elastic force adjustment mechanism, the blanking, punching and flipping compound die is optimized in function, the die sticking and sticking phenomenon are reduced, the maintenance cost of the die is reduced, and the service life of the die is extended.

[0083] In actual application, the operator can adjust the position of the wedge-shaped slider 4 by rotating the adjustment nut 6 according to the material withdrawal requirements, thereby changing the elastic force of the elastic component 2. This design makes the adjustment of the spring force more flexible and convenient, adapts to different material withdrawal requirements, and provides adaptive elastic force to assist the material withdrawal core to complete the material withdrawal action. At the same time, it simplifies the adjustment process of the elastic force, improves the convenience of operation, and reduces the adjustment time and labor cost.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0085] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
