Description

Technical Field

[0001] This application relates to the field of metal smelting technology, and in particular to a purification device. Background Technology

[0002] Currently, during the production of high-temperature alloy bars, shrinkage cavities are generated inside the bars. Depending on the needs of smelting, processing, or transportation, the longer bars are cut into several shorter bars of equal length. During the cutting process, impurities such as chip fragments, metal sand from the chips, and metal impurities on the surface of the bars can easily get mixed into the shrinkage cavities at the cutting point. These impurities can seriously affect the purity of the high-temperature alloy bars during remelting, thereby reducing key performance indicators such as the high-temperature performance and corrosion resistance of the alloy.

[0003] The traditional cleaning method involves placing the cut bar stock on an operating table, where the operator uses compressed air to target the shrinkage cavity and blows away the impurities inside the shrinkage cavity using the air pressure of the compressed air.

[0004] However, some bar stock has fine and deep shrinkage cavities, which cannot be effectively cleaned by compressed air. In fact, it may blow impurities to the deepest part of the shrinkage cavity, making them difficult to remove. These problems urgently need to be solved. Summary of the Invention

[0033] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0034] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0035] During the production of high-temperature alloy bars, shrinkage cavities can form inside the bars due to metal solidification shrinkage and other reasons. When long bars are cut into shorter sections, the end faces of the shrinkage cavities are exposed, making it easy for impurities (such as chips, sand particles, surface oxides, etc.) to be introduced during the cutting process. These impurities remain inside the shrinkage cavities and are difficult to remove.

[0036] Traditional methods use compressed air to purge, but because the shrinkage cavities are long and irregular in shape, the airflow cannot effectively penetrate to the bottom. This not only results in poor cleaning but may also "push" impurities deeper into the shrinkage cavities, affecting the purity of the material in subsequent remelting processes and thus reducing the alloy's key properties such as high-temperature strength and corrosion resistance.

[0037] like Figure 1-3 As shown, this disclosure proposes a purification device for purifying bar stock, comprising: a support frame 10 and an assembly assembly 20, wherein the assembly assembly 20 is slidably connected to the support frame 10, the assembly assembly 20 is capable of reciprocating along a first direction a, and the assembly assembly 20 includes a plurality of receiving units, which are spaced apart, and the receiving units are used to assemble bar stock along the first direction.

[0038] Understandably, the support frame 10, as the basic structure of the entire device, can be used to support other components. The support frame 10 can be fixed to the bearing surface, such as a workbench or the ground. The fixing method can be bolt fixing, welding fixing, etc., so that it has strong stability and can resist vibration. The material can be high-strength steel or stainless steel.

[0039] The assembly component 20 and the support frame 10 can be connected by guide columns, linear guides or ball screws, and can reciprocate up and down along a first direction, which can be a vertical direction perpendicular to the bearing surface.

[0040] Multiple receiving units are arranged at intervals on the assembly component 20. The arrangement can be horizontal, and the spacing between the receiving units can be reasonably set according to the diameter of the bar stock. This allows for the formation of more receiving units on the assembly component 20 for assembling the bar stock along the first direction. For example, the bar stock can be placed vertically in the receiving unit with the shrinkage end face facing down or towards the bearing surface. The axial direction of the bar stock is consistent with the first direction of movement of the assembly component 20, so that during the reciprocating motion of the assembly component 20 with the bar stock along the first direction, impurities in the shrinkage cavity at the end of the bar stock can be vibrated out by inertia.

[0041] During the working process, when the assembly component 20 drives the bar stock to move up and down reciprocally, due to the effects of gravity and acceleration, the impurities inside the bar stock's shrinkage cavity will try to maintain their original static or moving state due to inertia.

[0042] For impurities located within the cavity, the reciprocating motion of the assembly 20 in the first direction produces an oscillating effect that helps to loosen and eventually remove the impurities from the cavity, making it suitable for irregularly shaped, long, deep cavities that are difficult to clean with compressed air or other conventional methods.

[0043] In some embodiments, the receiving unit includes an assembly hole 211 for inserting a bar stock; the assembly assembly 20 includes a limiting member 21, the assembly hole 211 is disposed on the limiting member 21, and the axial direction of the assembly hole 211 is consistent with the first direction.

[0044] Understandably, the receiving unit includes one or more assembly holes 211, into which the bar stock is vertically inserted for positioning; the assembly hole 211 and the bar stock are clearance fit, allowing the bar stock to slide up and down inside; the axial direction of the assembly hole 211 is consistent with the first direction (i.e., the vertical direction), and the positioning and support of the bar stock are achieved through the assembly hole 211; the bar stock is allowed to move freely in the vertical direction within the assembly hole 211, and multiple receiving units can be arranged side by side on the assembly assembly 20 to achieve synchronous processing of multiple bars stock.

[0045] The limiting member 21 is disposed in the assembly component 20, and the assembly hole 211 is disposed on the limiting member 21. The limiting member 21 can be one or more plate-shaped structures with holes. When the limiting member 21 is a plate-shaped structure with holes, it can be divided into an upper plate and a lower plate along the first direction, and they are arranged at corresponding intervals. The bar is inserted into the upper plate and the lower plate along the first direction at the same time, which can further improve the limiting and guiding effect of the bar.

[0046] The limiting component 21 can provide guidance and limit for the bar stock, ensuring that the bar stock remains vertical during movement and preventing the bar stock from tilting or jamming during vibration. If there are two limiting plates, an upper and lower one can be provided to form a stable "guide rail" structure, which can improve the stability of the bar stock movement.

[0047] In some embodiments, the receiving unit further includes an assembly groove 221; the assembly assembly 20 further includes a first frame 22, the first frame 22 is connected to the limiting member 21, the assembly groove 221 is located inside the first frame 22, and the assembly groove 221 communicates with the assembly hole 211.

[0048] The first frame 22 has a hollow part 222 on the side away from the limiting member 21, and the hollow part 222 is connected to the assembly groove 221.

[0049] Understandably, to further enhance the device's impurity removal capability, guiding stability, and operational convenience, an assembly groove 221 is formed on the lower side of the limiting member 21 using the first frame 22. The end of the bar stock with the shrinkage cavity is placed in the assembly groove 221. A perforated portion 222 is provided on the side of the assembly groove 221 away from the limiting member 21, i.e., a perforated portion 222 is provided at the bottom of the groove. The perforated portion 222 can be a grid or a screen, serving to allow only impurities in the shrinkage cavity to be discharged, while preventing the bar stock from falling. The grid type can be composed of intersecting metal or plastic strips with gaps slightly smaller than the diameter of the bar stock. The screen type can have a fine mesh structure, allowing only impurity particles to pass through.

[0050] The limiting member 21 is located at the top and has multiple assembly holes 211 for inserting the bar stock and providing vertical guidance. The first frame 22 is connected below the limiting member 21 to form a downwardly extending cavity. The assembly groove 221 is formed in the first frame 22 to accommodate the shrinkage end of the bar stock. The hollow part 222 is located at the bottom of the assembly groove 221 (i.e., the bottom of the groove) for the discharge of impurities and to prevent the bar stock from falling.

[0051] In some embodiments, the assembly component 20 further includes a second frame 23, wherein the first frame 22 is disposed on the second frame 23;

[0052] The support frame 10 includes a frame body 11 and guide members 12. The guide members 12 are disposed on the frame body 11 along a first direction, and multiple guide members 12 are spaced apart and correspondingly disposed on the periphery of the support frame 10.

[0053] The second frame 23 is slidably mounted on the guide member 12 so that the assembly assembly 20 can reciprocate along the length direction of the guide member 12.

[0054] Understandably, the second frame 23, as the main load-bearing structure of the entire assembly 20, is slidably mounted on the guide member 12 of the support frame 10, and the first frame 22 can be set on the second frame 23.

[0055] The support frame 10 is the basic structure of the entire device, providing guidance and load-bearing functions. It includes the frame body 11 and guide members 12. The frame body 11 is typically a rectangular frame, with a stable structure that can be floor-mounted or integrated into the production line. The guide members 12 are arranged on the frame body 11 along a first direction (vertical direction), with multiple guide members 12 spaced apart around the periphery of the support frame 10 (e.g., at the four corners or both sides). The guide members 12 can be linear guides, linear bearings, or a combination of optical shafts and sliders. The guide members 12 slide against the second frame 23, allowing them to move precisely back and forth along the first direction, ensuring the stability and verticality of the assembly component 20 during movement. It should be noted that a limiting block is provided at the end of the guide member 12 to prevent the assembly component 20 from coming off during movement. The limiting block can be a metal fixing block with an outer contour much larger than the outer contour of the guide member 12, fixed by welding, or it can be a nut, tightened onto the end of the guide member 12 through a threaded structure to prevent the assembly component 20 from coming off.

[0056] In some embodiments, the drive component 30 is disposed on the support frame 10 and connected to the assembly component 20. The drive component 30 is used to drive the assembly component 20 to reciprocate along a first direction.

[0057] Understandably, the drive assembly 30 provides a power source to enable the assembly assembly 20 to reciprocate up and down along the guide 12, thereby achieving inertial vibration to remove impurities from the shrinkage cavity of the bar stock. The drive assembly 30 may include a servo motor, stepper motor, vibration motor, cylinder, or hydraulic cylinder, etc. The drive end of the drive assembly 30 may be connected to the first frame 22 or the second frame 23.

[0058] Working process: The bar stock is vertically inserted into the assembly hole 211 of the limiting member 21, and the reduced end enters the assembly groove 221 in the first frame 22;

[0059] The drive assembly 30 drives the first frame 22 or the second frame 23 to move up and down along the guide member 12. Under the action of inertia, the bar stock generates displacement relative to the first frame 22, which generates vibration. Impurities fall out from the shrinkage cavity and fall into the assembly groove 221. They are discharged through the bottom hollow part 222 (such as a screen / grid). After the bar stock is cleaned, it can be unloaded manually or automatically. If there is also a shrinkage cavity at the other end of the bar stock, the bar stock can be turned manually or automatically and the above steps can be repeated.

[0060] In some embodiments, the system further includes an elastic member 40, which is sleeved on the outside of the guide member 12. The elastic member 40 has a first end and a second end that are disposed opposite to each other. The first end abuts against the frame body 11 and the second end abuts against the second frame 23.

[0061] The drive assembly 30 includes a vibration motor, which is disposed on the second frame 23 and corresponds to the limiting member 21.

[0062] Understandably, the elastic element 40 is located on the outside of the guide 12 to provide a buffering effect, reduce the impact force of the assembly 20 during its up-and-down reciprocating motion, protect the equipment from excessive wear, and provide a certain damping effect when stopping or changing direction to prevent violent vibration. The elastic element 40 can be a spring, a rubber pad, or other elastic material.

[0063] The vibration motor is located at the lower end of the second frame 23 and corresponds to the position of the limiting member 21, that is, the projection of the vibration motor and the limiting member 21 along the first direction coincides.

[0064] The vibratory motor provides a vibration source for the bar stock, which further loosens impurities in the shrinkage cavity through high-frequency vibration; combined with the assembly component 20 moving up and down in the first direction, it enhances the effect of inertial cleaning; the vibration frequency and amplitude can be adjusted to adapt to different specifications and types of bar stock.

[0065] During the reciprocating motion, the bar stock is subjected to gravity and acceleration. Impurities in the shrinkage cavity gradually loosen and detach due to inertia. The high-frequency vibration generated by the vibrating motor further disturbs the inside of the shrinkage cavity, accelerating the shedding of impurities. The impurities fall into the assembly groove 221 and are discharged through the bottom hollow part 222. The elastic element 40 can play a buffering role during the movement, reduce the impact force, keep the equipment running smoothly, and prevent the support frame 10 from shaking excessively.

[0066] The vibration motor is electrically connected to the frequency converter via a cable. The frequency of the vibration motor is adjusted by rotating the frequency converter, and the effectiveness of the vibration is ensured by the change in frequency.

[0067] In some embodiments, a guide sleeve 231 is provided on the side of the second frame 23 facing the elastic member 40, and the opening of the guide sleeve 231 extends toward the first end to cover the outer periphery of the elastic member 40.

[0068] Understandably, in order to further improve the stability, guiding accuracy and service life of the device during movement, a guide sleeve 231 is provided on the side of the second frame 23 facing the elastic element 40 to guide and limit the elastic element 40.

[0069] Among them, the guide sleeve 231 can be a hollow cylindrical structure with its opening extending towards the frame body 11, wrapping around the outer periphery of the elastic element 40 and limiting it, which can prevent the elastic element 40 from deflecting during compression or extension, thereby improving the guiding accuracy and ensuring that the elastic element 40 is always subjected to force along the axial direction.

[0070] In some embodiments, the first frame 22 is provided with a sidewall 223 surrounding the circumferential direction; the limiting member 21 includes a leg 212, one end of which is fixedly disposed with the limiting member 21, and the other end extends toward the assembly groove 221.

[0071] The side wall 223 is provided with a first adjustment limiting part 50, and the support leg 212 is provided with a second adjustment limiting part 60 corresponding to the first adjustment limiting part 50. The distance between the assembly hole 211 and the assembly groove 221 is adjusted by adjusting the relative position of the first adjustment limiting part 50 and the second adjustment limiting part 60.

[0072] Understandably, an adjustable limiting structure was designed to accommodate bars of different lengths.

[0073] The side wall 223 of the first frame 22 can be a ring or rectangular frame structure, which can improve the overall structural strength. As the basis for setting the first adjustment limit part 50, the first adjustment limit part 50 is set on the side wall 223 and can be in the form of threaded hole, slide groove, slot or limit block, etc., to cooperate with the second adjustment limit part 60 on the limit member 21 to realize height / position adjustment.

[0074] The limiting member 21 can have multiple legs 212, such as three or four. One end of the leg 212 is fixedly connected to the limiting member 21, and the other end extends toward the assembly groove 221. The leg 212 is used to support the limiting member 21 and is connected to the first frame 22. The second adjusting limiting part 60 is provided on the leg 212 and is correspondingly provided to the first adjusting limiting part 50 on the side wall 223. It can be a limiting pin, adjusting bolt, buckle, etc. By adjusting their relative positions, the distance between the limiting member 21 and the assembly groove 221 can be changed.

[0075] During the adjustment process, the connection structure between the limiting member 21 and the first frame 22 is loosened; the relative positions of the first adjusting limiting part 50 and the second adjusting limiting part 60 are adjusted; for example, the limiting pin is inserted into different threaded holes, or the position of the limiting block in the slide is adjusted; after the connection is fixed, the height of the limiting member 21 relative to the assembly groove 221 can be changed.

[0076] Adjust the distance between the assembly hole 211 and the assembly groove 221 to accommodate bars of different lengths; after adjustment, retighten all components to ensure structural stability.

[0077] In some embodiments, the first adjusting limiting portion 50 has an elongated hole along a first direction, and the second adjusting limiting portion 60 has a circular hole; or...

[0078] The first adjusting limit part 50 consists of a plurality of longitudinally arranged circular holes, and the second adjusting limit part 60 consists of a circular hole; or,

[0079] The first adjustment limiting part 50 is a circular hole, and the second adjustment limiting part 60 is a plurality of circular holes arranged longitudinally;

[0080] In this configuration, fasteners pass through the first adjustment limiting part 50 and the second adjustment limiting part 60, thereby fixing the limiting member 21 relative to the first frame 22.

[0081] Understandably, one possible solution is that the first adjusting limit part 50 is located on the side wall 223 and is an elongated hole extending vertically; the second adjusting limit part 60 is located on the support leg 212 and is a round hole with a fixed position; during adjustment, the fastener is inserted into the round hole and can slide within the elongated hole, thereby achieving continuous height adjustment of the limiting part 21; after adjustment, tightening the fastener will fix it, achieving continuous adjustability, flexible positioning, easy processing and installation, and a small number of fasteners, resulting in a simple structure.

[0082] Another design involves a first adjusting limit part 50 consisting of multiple longitudinally distributed circular holes located on the side wall 223; and a second adjusting limit part 60 consisting of a single circular hole located on the support leg 212. During adjustment, a suitable circular hole is selected for connection according to the required height; and fasteners are used to pass through the two circular holes to complete the fixation. This design offers accurate positioning, high structural rigidity, and good long-term stability.

[0083] Another option is that the first adjustment limiting part 50 is a fixed circular hole, which is set on the side wall 223; the second adjustment limiting part 60 is a plurality of longitudinally arranged circular holes, which are set on the support leg 212; the support leg 212 can be connected to different circular hole positions as needed; after adjusting the height, it is fixed by fasteners.

[0084] Among them, the outrigger 212 is a variable part, which is easy to replace or quickly adjust; the round hole on the fixed side wall 223 can reduce the impact on the main structure and is also suitable for segmented adjustment scenarios.

[0085] In some embodiments, the assembly further includes a dust collection tray 70, which is spaced apart from the assembly component 20 and corresponds to the cutout portion 222.

[0086] Understandably, the dust collection tray 70 is positioned below the assembly component 20; corresponding to the perforated portion 222 (such as a screen or grid); and maintaining a certain distance from the assembly component 20 to avoid interference during movement. The dust collection tray 70 can be a flat, recessed, or tray structure with guide edges, used to receive impurities discharged from the perforated portion 222; preventing impurities from scattering outside the equipment and maintaining a clean working environment. It should be noted that in the above embodiments, the descriptions of each embodiment have different focuses; for parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
