Description

Technical Field

[0001] This utility model relates to a multi-channel lubrication and anti-tear mechanism and a magnesium alloy complex profile extrusion die. Background Technology

[0002] Magnesium alloys, with their excellent properties such as lightweight, high strength, good shock absorption, and recyclability, are increasingly widely used in aerospace, automotive manufacturing, and electronic equipment industries. Extrusion molding, as the core processing technology for magnesium alloy profiles, can efficiently produce profiles with complex cross-sections. However, in actual production, the support and lubrication issues during the profile extrusion stage have always been a key bottleneck restricting the improvement of product quality.

[0003] During the extrusion process of magnesium alloy profiles, the newly formed profiles have high temperatures and weak structural stability, requiring precise positioning and stable support from a support mechanism to prevent bending and deformation due to their own weight or extrusion traction. However, existing support mechanisms mostly adopt a fixed structural design, and the position of the support points cannot be flexibly adjusted, making it difficult to adapt to magnesium alloy extruded profiles with different cross-sectional specifications and sizes. For profiles with complex cross-sections or variable dimensions, the fixed support points are prone to uneven contact and support imbalance, resulting in large deviations in the shape accuracy of the profiles after extrusion, increasing the difficulty of subsequent correction. In view of this, this utility model proposes a multi-channel lubrication and anti-tear mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-channel lubrication and anti-tear mechanism and a magnesium alloy complex profile extrusion die to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-channel lubrication and anti-tear mechanism includes two sets of support rings, and multiple sets of connecting plates are provided between the two sets of support rings. The support ring is provided with multiple sets of connecting grooves, which are arranged in a circular array around the axis of the support ring. Each connecting groove is provided with a mounting threaded hole, and an adjustment component is provided in the mounting threaded hole. The adjustment component is provided with a lubricating ball, and the adjustment component cooperates with the mounting threaded hole to adjust the position of the lubricating ball within the support ring for support and lubrication.

[0006] As an improvement to the above technical solution, the connecting plate includes two sets of connecting parts, and a positioning part is provided between the two sets of connecting parts; The connecting part is positioned to match the connecting groove, and a connecting hole is provided on the connecting part, which matches the mounting threaded hole.

[0007] As an improvement to the above technical solution, a positioning connection slot is provided on the positioning part, and the positioning connection slot is located at the center of the positioning part.

[0008] As an improvement to the above technical solution, the adjustment component includes an adjustment screw, which is threadedly engaged with a mounting threaded hole; The lubricating ball is rolled at the end of the adjusting screw.

[0009] As an improvement to the above technical solution, a clamping nut is provided on the outer wall of the adjusting screw. The clamping nut is threadedly engaged with the adjusting screw, so that the clamping nut contacts the connecting part and presses the connecting plate into the connecting groove.

[0010] As an improvement to the above technical solution, the adjusting screw is provided with a lubrication cavity, and the lubrication cavity is provided with lubricating fluid; The adjusting screw is provided with an integrally formed hexagonal block, the hexagonal block has a liquid inlet hole, and a sealing plug is provided in the liquid inlet hole.

[0011] As an improvement to the above technical solution, the adjusting screw is provided with a liquid outlet hole, which is matched with the position of the lubricating ball, so that the lubricating fluid flows from the lubrication cavity to the surface of the lubricating ball.

[0012] A magnesium alloy complex profile extrusion die includes a multi-channel lubrication and anti-tear mechanism as described in any one of the above claims. The extrusion die is provided with a first die core and a second die core, and the first die core and the second die core are compatible with each other. The diameter of the support ring is the same as the diameter of the second mold core, and the support ring and the second mold core are coaxially arranged, so that the magnesium alloy extruded profile enters the support ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are: An integrated support frame consisting of two sets of support rings and multiple sets of connecting plates, along with multiple sets of connecting grooves and corresponding mounting threaded holes arranged in a ring array around the axis on the support rings, provides a stable installation reference for the adjustment components. The position of the lubricating balls within the support rings is adjustable through the cooperation of the adjustment components and the mounting threaded holes. This allows the multiple sets of lubricating balls to flexibly adjust their contact positions according to the cross-sectional specifications and dimensions of the magnesium alloy extruded profile, ensuring that all sets of lubricating balls are in reliable contact with the profile surface. This forms an all-round, multi-point support structure, effectively avoiding bending and deformation problems caused by support imbalance during the profile's discharge displacement process, and significantly improving the shape accuracy of the profile after discharge. Multiple sets of lubricating spheres distributed in a ring array, combined with the independent position adjustment function of each set of lubricating spheres, form a multi-channel lubrication path, so that the lubrication effect covers the entire outer peripheral surface of the magnesium alloy extruded profile, with no lubrication blind spots. During the profile discharge displacement, the lubricating spheres form a rolling contact with the profile surface. With the action of the multi-channel lubrication medium, the friction coefficient between the profile and the supporting components is greatly reduced, reducing friction loss. At the same time, it realizes immediate lubrication protection after the profile is discharged, fundamentally avoiding defects such as scratches and pulls caused by friction on the profile surface, and significantly improving the surface quality of the magnesium alloy extruded profile.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: like Figure 1-7As shown, this embodiment proposes a multi-channel lubrication and anti-tear mechanism, including two sets of support rings 40, and multiple sets of connecting plates 50 are provided between the two sets of support rings 40; The support ring 40 is provided with multiple sets of connecting grooves 41, which are arranged in a circular array around the axis of the support ring 40. Each connecting groove 41 is provided with a mounting threaded hole 42, and an adjustment component 30 is provided in the mounting threaded hole 42. A lubricating ball 60 is provided on the adjustment component 30. The adjustment component 30 cooperates with the mounting threaded hole 42, so that the lubricating ball 60 can be adjusted in position within the support ring 40 for support and lubrication.

[0018] In this embodiment, when lubricating and supporting the magnesium alloy extruded profile after it is discharged, two sets of support rings 40 are connected to multiple sets of connecting plates 50. The magnesium alloy extruded profile is first placed in the support rings 40. Then, the lubricating ball 60 is moved by the adjusting component 30 until the lubricating ball 60 contacts the surface of the magnesium alloy extruded profile. The position of the lubricating ball 60 is then repeatedly adjusted so that multiple sets of lubricating balls 60 contact the surface of the magnesium alloy extruded profile. During the displacement of the magnesium alloy extruded profile, the magnesium alloy extruded profile is supported and lubricated. Of course, the above steps can be repeated to form multi-channel lubrication. An integrated support frame consisting of two sets of support rings 40 and multiple sets of connecting plates 50, along with multiple sets of connecting grooves 41 arranged in a ring array around the axis and corresponding mounting threaded holes 42 on the support rings 40, provides a stable installation reference for the adjustment assembly 30. The position of the lubricating ball 60 within the support rings 40 is adjustable by the cooperation of the adjustment assembly 30 and the mounting threaded holes 42. This allows the multiple sets of lubricating balls 60 to flexibly adjust their contact positions according to the cross-sectional specifications and dimensions of the magnesium alloy extruded profile, ensuring that all sets of lubricating balls 60 are in reliable contact with the profile surface. This forms an all-round, multi-point support structure, effectively avoiding bending and deformation problems caused by support imbalance during the profile's discharge displacement, and significantly improving the shape accuracy of the profile after discharge. Multiple sets of lubricating spheres 60 distributed in a ring array, combined with the independent position adjustment function of each set of lubricating spheres 60, form a multi-channel lubrication path, so that the lubrication effect covers the entire outer peripheral surface of the magnesium alloy extruded profile, with no lubrication blind spots. During the profile discharge displacement process, the lubricating spheres 60 form a rolling contact with the profile surface. With the action of the multi-channel lubrication medium, the friction coefficient between the profile and the supporting components is greatly reduced, reducing friction loss. At the same time, it realizes immediate lubrication protection after the profile is discharged, fundamentally avoiding defects such as scratches and pulls on the profile surface caused by friction, and significantly improving the surface quality of the magnesium alloy extruded profile.

[0019] Specifically, the connecting plate 50 includes two sets of connecting parts 51, and a positioning part 53 is provided between the two sets of connecting parts 51; The connecting part 51 is matched with the connecting groove 41, and the connecting part 51 is provided with a connecting hole 52, which matches the mounting threaded hole 42.

[0020] In this embodiment, the connection part 51 of the connecting plate 50 and the connection groove 41 of the support ring 40 are precisely matched, and the connection hole 52 of the connecting part 51 and the mounting thread hole 42 in the connection groove 41 are adapted to each other. This enables the connection plate 50 and the support ring 40 to be positioned and assembled quickly, avoiding problems such as hole offset and position misalignment during the assembly process. This significantly improves the assembly accuracy and efficiency, and reduces the impact of assembly errors on the overall performance of the mechanism.

[0021] Specifically, the positioning part 53 is provided with a positioning connection slot 54, which is located at the center of the positioning part 53.

[0022] In this embodiment, the positioning connection slot 54 facilitates the connection of the connecting plate 50 to the external environment via bolts, thereby facilitating the overall positioning process.

[0023] Specifically, the adjustment assembly 30 includes an adjustment screw 32, which is threadedly engaged with the mounting threaded hole 42; The lubricating ball 60 is rolled at the end of the adjusting screw 32.

[0024] In this embodiment, the adjusting screw 32 and the mounting threaded hole 42 adopt a threaded engagement structure. Utilizing the high precision characteristics of threaded transmission, the radial displacement of the lubricating ball 60 within the support ring 40 can be finely adjusted by rotating the adjusting screw 32. The extension amount of the lubricating ball 60 can be precisely controlled according to the cross-sectional dimensions and shape of the magnesium alloy extruded profile, ensuring that the lubricating balls 60 distributed in multiple annular arrays can form uniform and reliable contact with the profile surface. This avoids local support failure or lubrication loss caused by uneven contact, providing a structural basis for multi-channel uniform lubrication and stable support.

[0025] Specifically, the outer wall of the adjusting screw 32 is provided with a clamping nut 31, which is threadedly engaged with the adjusting screw 32, so that the clamping nut 31 contacts the connecting part 51 and presses the connecting plate 50 into the connecting groove 41.

[0026] In this embodiment, the clamping nut 31 and the adjusting screw 32 form a double locking structure through threaded engagement. After the adjusting screw 32 completes the position calibration of the lubricating ball 60, the clamping nut 31 is tightened to make it fit tightly with the connecting part 51 of the connecting plate 50, firmly pressing the connecting plate 50 into the connecting groove 41 of the support ring 40, so that the connecting plate 50 and the support ring 40 form an integrated rigid connection, effectively dispersing the radial load and axial impact force generated during the displacement of the magnesium alloy extruded profile, avoiding gaps, loosening or relative displacement at the connecting part 51, and significantly improving the structural bearing strength and long-term stability of the entire mechanism.

[0027] Specifically, the adjusting screw 32 is provided with a lubrication cavity 36, and the lubrication cavity 36 is provided with lubricating fluid; The adjusting screw 32 is provided with an integrally formed hexagonal block 33, the hexagonal block 33 has a liquid inlet hole 35, and a sealing plug 34 is provided in the liquid inlet hole 35.

[0028] In this embodiment, the built-in lubrication cavity 36 of the adjusting screw 32 can stably store a sufficient amount of lubricating fluid, providing a continuous source of lubricating medium for the lubricating ball 60, thus avoiding the problems of easy loss and discontinuous supply of lubricating fluid in traditional external lubrication methods.

[0029] Specifically, the adjusting screw 32 is provided with a liquid outlet hole 37, which is matched with the position of the lubricating ball 60, so that the lubricating fluid flows from the lubrication cavity 36 to the surface of the lubricating ball 60.

[0030] In this embodiment, the position matching design between the liquid outlet 37 and the lubricating ball 60 enables the directional delivery of lubricating fluid to the surface of the lubricating ball 60, ensuring uninterrupted lubrication during the displacement of the magnesium alloy extruded profile, and fundamentally guaranteeing the stability and durability of the anti-tear effect.

The extrusion die is provided with a first die core 10 and a second die core 20, which are compatible with each other. The diameter of the support ring 40 is the same as the diameter of the second mold core 20, and the support ring 40 and the second mold core 20 are coaxially arranged, so that the magnesium alloy extruded profile enters the support ring 40.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
