Description

Technical Field

[0001] This utility model relates to the field of silver forging, and in particular to a silver forging forming equipment. Background Technology

[0002] In traditional silver forging processes, there are several problems with billet size inspection and the forging process itself. For example, current methods often involve manual caliper measurement or visual inspection to check the size of silver billets. This method is not only inefficient, but manual operation is also prone to measurement errors, making it difficult to quickly and accurately obtain key data such as billet thickness before forging. Utility Model Content

[0003] The purpose of this invention is to provide a silver forging and forming device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A silver forging forming device includes a placement groove on a base, and a detection mechanism is provided on the placement groove.

[0006] In a preferred embodiment, the detection mechanism includes a grating sensor, and the placement slot is provided with a reserved port (measuring port), on which the grating sensor is connected.

[0007] Furthermore, if the grating sensor detects that the billet size exceeds the preset range, the system will issue an alarm to prompt the operator to make adjustments, ensuring the accuracy of the forging process.

[0008] Specifically, the grating sensor continuously monitors the change in billet thickness and feeds the data back to the control system, which adjusts the pressure and stroke of the hydraulic cylinder in real time to ensure forging accuracy.

[0009] Furthermore, the grating sensor is equipped with vacuum-insulated glass.

[0010] In a preferred embodiment, the placement groove is provided with a billet homogenization activation module, the billet homogenization activation module includes an electromagnetic coil, the placement groove is provided with a groove, an electric cylinder two is connected to the groove, and the output end of the electric cylinder two is driven by a piston rod to connect to the electromagnetic coil.

[0011] Furthermore, when an alternating current is passed through the electromagnetic coil, the resulting alternating magnetic field induces a current inside the silver billet, which, based on the Lorentz force, drives the metal inside the billet to generate a stirring motion.

[0012] Specifically, if silver is in a liquid or softened state at high temperature, a magnetic field with a lower frequency and a larger current can induce strong macroscopic convection, rapidly mix raw materials of different components, eliminate macroscopic segregation caused by density differences, and make the solute elements evenly distributed.

[0013] Furthermore, once the billet homogenization reaches the predetermined effect, the hydraulic cylinder on the top plate begins to operate. Its piston rod pushes the slider to slide downwards along the slide rail inside the base, causing the top block at the bottom to apply forging pressure to the silver billet for forging, ensuring that the billet deforms uniformly under pressure and is formed.

[0014] In a preferred embodiment, the billet homogenization activation module is arranged in a mirror-symmetric configuration.

[0015] In a preferred embodiment, a top plate is connected to the top of the base.

[0016] In a preferred embodiment, a hydraulic cylinder is connected to the top plate, and a slider is driven to the output end of the hydraulic cylinder via a piston rod.

[0017] Furthermore, the hydraulic cylinder on the top plate drives the slider and top block to a high position to avoid interfering with the loading of the billet.

[0018] In a preferred embodiment, the bottom of the slider is connected to a top block.

[0019] Furthermore, the surface of the top block undergoes a special hardening treatment to withstand high pressure and ensure the surface quality of the billet (the surface of the top block adopts a special hardening treatment process in the existing technology, such as carburizing and quenching, nitriding, laser cladding or thermal spraying of tungsten carbide coating, etc.).

[0020] In a preferred embodiment, the base is provided with a slide rail inside.

[0021] In a preferred embodiment, a slider is attached to and slides on the slide rail.

[0022] In a preferred embodiment, a side plate is connected to the base, and an electric cylinder is connected to the side plate.

[0023] In a preferred embodiment, the output end of the electric cylinder is connected to a placement groove via a piston rod.

[0024] Furthermore, the electric cylinder on the side plate is in its initial retracted state, ensuring that the placement slot is in a position that facilitates loading the billet.

[0025] Furthermore, the placement groove is made of high-temperature resistant and wear-resistant material, which can effectively prevent the billet from sticking to the groove body during high-temperature forging.

[0026] Specifically, the measurement port reserved on the placement slot precisely aligns with the grating sensor. The grating sensor emits a parallel beam of light, and when the silver billet blocks the beam, causing a signal change, it can quickly and accurately measure the initial thickness, width, and other dimensional data of the billet. The detection data is transmitted in real time to the external control system of the equipment, serving as the basis for subsequent adjustments to forging parameters.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] 1. This utility model uses a grating sensor to perform real-time size detection on the billet, which can quickly and accurately obtain data such as the initial thickness and width of the billet and transmit the information to the external control system in real time. This mechanism can automatically adjust the forging parameters, such as the hydraulic cylinder pressure and the working mode of the electromagnetic coil, based on the detection results, so as to realize the precision and intelligence of the forging process, improve the product size accuracy, and significantly reduce the scrap rate.

[0029] 2. The billet homogenization excitation module of this utility model, which is set up with mirror symmetry, generates an alternating magnetic field through an electromagnetic coil and drives metal stirring by electromagnetic induction and Lorentz force. It can effectively eliminate macroscopic and microscopic segregation of silver billet. Whether it is promoting rapid mixing of components in the melting stage or refining grains and removing inclusions in the forging stage, it can improve the density and uniformity of the material, and fundamentally improve the internal quality and mechanical properties of silver products.

[0042] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0043] See Figure 1-5 The silver forging equipment provided in this embodiment includes a placement groove 5 on a base 1, and a detection mechanism is provided on the placement groove 5.

[0044] The detection mechanism includes a grating sensor 13. The placement slot 5 is provided with a reserved measuring port, and the grating sensor 13 is connected to the reserved measuring port.

[0045] In this specific embodiment, before forging begins, the operator first places the silver billet into the placement slot 5 on the base 1. The electric cylinder 7 can adjust the position of the placement slot 5 according to the instructions of the external control system for easy loading and unloading.

[0046] Furthermore, the electric cylinder 7 on the side plate 6 is in its initial retracted state, ensuring that the placement slot 5 is in a position that facilitates loading the billet.

[0047] Furthermore, the hydraulic cylinder 3 on the top plate 2 drives the slider 4 and the top block 9 to a high position to avoid interference with the loading of the billet.

[0048] Furthermore, the placement groove 5 is made of high-temperature resistant and wear-resistant material, which can effectively prevent the billet from sticking to the groove body during high-temperature forging.

[0049] Specifically, the measurement port reserved on the placement slot 5 is precisely aligned with the grating sensor 13. The grating sensor 13 emits a parallel light beam, and when the silver billet blocks the light beam, causing a signal change, it can quickly and accurately measure the initial thickness, width, and other dimensional data of the billet. The detection data is transmitted in real time to the external control system of the equipment as the basis for subsequent forging parameter adjustments.

[0050] Furthermore, the grating sensor 13 is equipped with vacuum-insulated glass.

[0051] Furthermore, if the billet size is detected to be outside the preset range, the system will issue an alarm to prompt the operator to make adjustments to ensure the accuracy of the forging process.

[0052] The placement groove 5 is equipped with a billet homogenization activation module, which includes an electromagnetic coil 12. The placement groove 5 has a groove 10, and an electric cylinder 11 is connected to the groove 10. The output end of the electric cylinder 11 is driven by a piston rod to connect to the electromagnetic coil 12.

[0053] In this embodiment, the billet homogenization activation module is set up in a mirror-symmetric manner.

[0054] In this specific embodiment, after the billet loading and dimensional detection are completed, the electric cylinder 11 is activated, and its piston rod pushes the electromagnetic coil 12 along the slide rail in the groove 10 toward the silver billet. Since the billet homogenization excitation module adopts a mirror-symmetrical arrangement, the electromagnetic coils 12 on both sides can simultaneously apply electromagnetic force to the billet from different directions.

[0055] Furthermore, when an alternating current is applied to the electromagnetic coil 12, the resulting alternating magnetic field induces a current inside the silver billet, which, based on the Lorentz force, drives the metal inside the billet to generate a stirring motion.

[0056] Specifically, the core components of the electromagnetic stirring device are the electromagnetic coil and the external control system. When an alternating current is passed through the electromagnetic coil, a periodically changing alternating magnetic field is generated around the silver billet. According to the law of electromagnetic induction, an induced electromotive force is generated inside the silver (as a conductor) in the alternating magnetic field, which in turn generates an induced current (eddy current). At this time, the induced current interacts with the magnetic field, generating an electromagnetic force inside the silver according to the Lorentz force law. Since the direction and magnitude of the electromagnetic force change with the alternating magnetic field, it drives the metal inside the silver, which is in a liquid or high-temperature plastic state, to produce a stirring motion, thus achieving dynamic stirring of the molten metal or high-temperature billet.

[0057] Furthermore, by adjusting the frequency, intensity, and waveform of the current supplied to the electromagnetic coil through an external control system, the characteristics of the alternating magnetic field can be precisely controlled. Lower current frequencies generate stronger electromagnetic forces, suitable for promoting macroscopic flow of metals; higher current frequencies can induce more intense microscopic stirring. For example, in the early stages of silver smelting and forging, a low-frequency, high-current method is used to quickly mix raw materials of different compositions; during the forging stage, a high-frequency, low-current method is used to refine the microstructure and eliminate localized compositional inhomogeneities.

[0058] Specifically, if silver is in a liquid or softened state at high temperature, a magnetic field with a lower frequency and a larger current can induce strong macroscopic convection, rapidly mix raw materials of different components, eliminate macroscopic segregation caused by density differences, and make the solute elements evenly distributed.

[0059] In a specific embodiment of this invention, as the billet gradually takes shape, the current frequency and intensity of the electromagnetic coil 12 can be adjusted by an external control system to switch to a high-frequency, low-current mode, thereby initiating micro-stirring, refining the grain structure, avoiding dendrite segregation, and simultaneously helping the tiny pores and inclusions inside the billet to be discharged or compacted under the dual action of stirring and forging pressure, thus improving the material density.

[0060] Furthermore, once the billet homogenization reaches the predetermined effect, the hydraulic cylinder 3 on the top plate 2 begins to operate. Its piston rod pushes the slider 4 to slide downward along the slide rail 8 inside the base 1, which in turn drives the top block 9 at the bottom to apply forging pressure to the silver billet for forging, ensuring that the billet deforms uniformly under pressure and is formed.

[0061] Furthermore, the surface of the top block 9 undergoes a special hardening treatment to withstand high pressure and ensure the surface quality of the billet (the surface of the top block 9 adopts a special hardening treatment process in the existing technology, such as carburizing and quenching, nitriding, laser cladding or thermal spraying of tungsten carbide coating, etc.).

[0062] Specifically, the grating sensor 13 continuously monitors the change in billet thickness and feeds the data back to the control system, which adjusts the pressure and stroke of the hydraulic cylinder 3 in real time to ensure forging accuracy.

[0063] The top of the base 1 is connected to the top plate 2.

[0064] A hydraulic cylinder 3 is connected to the top plate 2, and the output end of the hydraulic cylinder 3 is driven by a piston rod to connect to a slider 4.

[0065] The bottom of slider 4 is connected to top block 9.

[0066] The base 1 has a slide rail 8 inside.

[0067] A slider 4 slides on the slide rail 8.

[0068] A side plate 6 is connected to the base 1, and an electric cylinder 7 is connected to the side plate 6.

[0069] The output end of the electric cylinder 7 is connected to the placement groove 5 via a piston rod.

[0070] In this specific embodiment, after forging is completed, the hydraulic cylinder 3 drives the top block 9 to rise and reset, and the electric cylinder 7 moves the placement slot 5 to the unloading position, allowing the operator to safely remove the formed silver product. The electric cylinders 11 on both sides drive the electromagnetic coils 12 back to their initial positions, preparing for the next forging.

[0071] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0072] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
