Description

Technical Field

[0001] The present invention relates to the technical field of alloy materials, and in particular, to an extrusion preparation device for a babbitt alloy composite material and a preparation method thereof. Background Art

[0002] The requirements for babbitt alloy bearing materials in terms of high service temperature, low starting friction force, and low friction coefficient are increasing day by day. Introducing reinforcing fibers into babbitt alloy is an ideal solution. However, there are problems such as large density difference, non-wetting at the interface, and difficult metallurgical compatibility between babbitt alloy and reinforcing fibers, making it impossible to prepare a composite material of babbitt alloy and reinforcing fibers with good performance by the traditional melting-casting method. This has caused the research on babbitt alloy and reinforcing fiber composite materials to stagnate to a certain extent.

[0003] At present, there are some powder metallurgy methods and thermal spraying methods to mix reinforcing fibers relatively uniformly into metal materials, but these methods can only prepare small workpieces and cannot prepare large workpieces. And babbitt alloy bearings are basically applied in medium and large-sized bearing equipment, resulting in the difficulty of applying these current processes. Moreover, these processes require professional equipment, resulting in large investment, complex processes, and long cycles. There is still a long way to go before industrial application. Therefore, an extrusion preparation device and a preparation method for babbitt alloy composite materials are proposed to solve the problems. Summary of the Invention

[0004] The first object of the present invention is to provide an extrusion preparation device for babbitt alloy composite materials;

[0007] In the related art, there are problems such as a large density difference, non-wetting at the interface, and difficult metallurgical compatibility between babbit alloy and reinforcing fibers, which make it impossible to prepare a composite material of babbit alloy and reinforcing fibers with good performance by the traditional melting-casting method. Using powder metallurgy and thermal spraying methods can only prepare small workpieces and cannot prepare large workpieces. And babbit alloy bearings are basically used in medium and large-sized bearing equipment, resulting in the difficulty of applying these current processes. Moreover, these processes require professional equipment, leading to large investment, complex processes, and long cycles. The present invention provides an extrusion preparation device for babbit alloy composite materials, adding a mixture of babbit alloy and reinforcing fibers to a containing device, and stamping and mixing the mixture through a stamping device. The first punch and the second punch alternately stamp and mix the babbit alloy and the reinforcing fibers, causing the babbit alloy and the reinforcing fibers to continuously move relative to each other, and finally achieving a state where the reinforcing fibers are evenly distributed in the babbit alloy.

[0014] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The detachable design of the first mold and the second mold facilitates taking out the processed composite material from the receiving inner cavity; after the composite material is stamped and mixed, the first mold and the second mold are disassembled to separate the composite material from the receiving device; due to continuous stamping of the composite material, the composite material is welded to the extrusion mold under high pressure. Adopting such a design can avoid this situation and make the discharging easier.

By using the reciprocating and alternating movement of the second punch and the first punch, the babbit alloy and the reinforcing fibers continuously move relative to each other, and finally reach a state where the reinforcing fibers are evenly distributed in the babbit alloy.

[0029] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the method of layered and spaced stacking of the babbitt alloy plate and the reinforcing fibers is adopted, so that the reinforcing fibers have a relatively uniform initial value in the babbitt alloy, thereby reducing the number of stamping processes, thereby greatly improving the processing efficiency, and also making the distribution of the reinforcing fibers in the composite material more uniform.

[0030] In one embodiment of the present invention, S300 specifically includes:

Detailed implementation manners

[0050] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0051] Next, refer to Figure 1-6 Describe the technical solutions of some embodiments of the present invention.

[0052]

First Embodiment

[0053] As Figure 1 shown, the embodiment of the present invention provides an extrusion preparation device 10 for a babbit alloy composite material, including: an accommodating device 100, the accommodating device 100 includes a heating device 130 and has an accommodating inner cavity 110, the accommodating inner cavity 110 is used to accommodate babbit alloy and reinforcing fibers, and the heating device 130 is used to apply heat to the accommodating inner cavity 110 to heat the babbit alloy and the reinforcing fibers; a stamping device 200, the stamping device 200 includes a first punch 210 and a second punch 220, and the first punch 210 and the second punch 220 are used to reciprocate alternately in the accommodating inner cavity 110 to stamp the mixed babbit alloy and reinforcing fibers.

[0054] In the related art, there are problems such as a large density difference, non-wetting at the interface, and difficult metallurgical compatibility between babbit alloy and reinforcing fibers, which make it impossible to prepare a composite material of babbit alloy and reinforcing fibers with good performance by the traditional melting-casting method. Using powder metallurgy and thermal spraying methods can only prepare small workpieces and cannot prepare large workpieces. And babbit alloy bearings are basically used in medium and large-sized bearing equipment, resulting in the difficulty of applying these current processes. Moreover, these processes require professional equipment, leading to large investment, complex processes, and long cycles. The present invention provides an extrusion preparation device 10 for babbit alloy composite materials. A mixture of babbit alloy and reinforcing fibers is added to the accommodating device 100, and the mixture is stamped and mixed by a stamping device 200. The first punch 210 and the second punch 220 alternately stamp and mix the babbit alloy and the reinforcing fibers, causing the babbit alloy and the reinforcing fibers to continuously move relative to each other, and finally achieving a state where the reinforcing fibers are evenly distributed in the babbit alloy. The resulting composite material of babbit alloy and reinforcing fibers has uniform distribution of reinforcing fibers, high density of the composite material, and excellent comprehensive performance.

[0055] In this embodiment, the accommodating device 100 further includes: an extrusion die 120, the extrusion die 120 surrounding and defining an accommodating inner cavity 110; a fixed seat 140, the fixed seat 140 sleeved outside the extrusion die 120; wherein, the inner wall of the heating device 130 is attached to the outer wall of the extrusion die 120; the inner wall of the fixed seat 140 cooperates with the outer wall of the extrusion die 120 and is used to fix the extrusion die 120.

[0056] Specifically, the fixed seat 140 is sleeved outside the extrusion die 120, playing a role in fixing and fastening the extrusion device, preventing the extrusion die 120 from shaking during the stamping process, thereby reducing the quality of the processed composite material; the heating device 130 is arranged outside the extrusion die 120. During the stamping process, the composite material in the extrusion die 120 is heated, improving the plasticity of the babbit alloy, reducing the deformation resistance, making it easy to flow and form, and obtaining a good forged microstructure. At the same time, arranging the heating device 130 around and attached to the extrusion die 120 can make the composite material uniformly heated, making the internal structure of the processed composite material more uniform and stable, while reducing the heating time and improving the processing efficiency.

[0057] For example, the fixed seat 140 is provided with a locking mechanism to facilitate the disassembly and assembly of the extrusion device.

[0058] In this embodiment, the extrusion die 120 includes: a first die 121, the first die 121 including a first inner cavity 121a; a second die 122, the second die 122 including a second inner cavity 122a; wherein, the first die 121 and the second die 122 are symmetrically arranged, and the first inner cavity 121a and the second inner cavity 122a together form at least part of the accommodating inner cavity 110.

[0059] Specifically, the first inner cavity 121a and the second inner cavity 122a together form at least part of the accommodating cavity 110 for containing the mixture of babbitt alloy and reinforcing fibers. At the same time, the extrusion die 120 is set in two parts, which is beneficial to the transportation of the device and reduces the occupied space.

[0060] For example, the bottom of the extrusion die 120 is set to an inner round bottom structure, so that when the surrounding composite material is extruded, it directly flows to the middle, and when the composite material in the middle part is extruded, it flows to the surrounding, further promoting the mixing of babbitt alloy and reinforcing fibers, and making the distribution of reinforcing fibers in the composite material more uniform.

[0061] In this embodiment, the first die 121 and the second die 122 are detachably arranged.

[0062] Specifically, the detachable design of the first die 121 and the second die 122 facilitates the removal of the processed composite material from the accommodating cavity 110; when the stamping and mixing of the composite material are completed, the first die 121 and the second die 122 are disassembled to separate the composite material from the accommodating device 100; due to the continuous stamping of the composite material, the composite material is welded to the extrusion die 120 under high pressure. Adopting such a design can avoid this situation and make the discharging easier.

[0063] For example, the contact surfaces of the first die 121 and the second die 122 should fit each other and should be flat and smooth to prevent the composite material from entering the gap between the first die 121 and the second die 122.

[0064] For another example, a layer of sealing material should be provided between the first die 121 and the second die 122, which can also prevent the composite material from entering the gap between the first die 121 and the second die 122.

[0065] In this embodiment, the second punch 220 includes: a cavity 221 that penetrates the internal space of the second punch 220; wherein, at least part of the first punch 210 is formed into a columnar structure, and during at least part of the alternating reciprocating movement of the first punch 210 and the second punch 220, the outer wall of the columnar structure of the first punch 210 fits with the inner wall of the cavity 221 of the second punch 220.

[0066] Specifically, the combination of the first punch 210 and the second punch 220 can fully stamp and mix the materials at different positions in the accommodating cavity 110, making the distribution of reinforcing fibers in the babbitt alloy more uniform and improving the quality of the composite material.

[0067] For example, the side shapes of the first punch 210, the second punch 220, and the accommodating inner cavity 110 are all cylindrical. With such a design, there are no dead corners in the device, which can fully mix the babbit alloy and the reinforcing fibers, avoiding the phenomenon of accumulation of reinforcing fibers or babbit alloy in some parts of the composite material.

[0068] In this embodiment, the end of the first punch 210 protrudes towards the end close to the accommodating device 100; the end of the second punch 220 is recessed towards the end close to the accommodating device 100.

[0069] Specifically, through the extrusion of the first punch 210, the babbit alloy and the reinforcing fibers in the middle part move towards the periphery of the extrusion die 120, and then through the second punch 220, the babbit alloy and the reinforcing fibers around the extrusion die 120 move towards the center of the extrusion die 120. By using the reciprocating alternating movement of the second punch 220 and the first punch 210, the babbit alloy and the reinforcing fibers continuously undergo relative movement, and finally reach a state where the reinforcing fibers are evenly distributed in the babbit alloy.

[0070] For example, the end of the first punch 210 is a circular protrusion, and the end of the second punch 220 is a circular depression; the use of circular protrusions and depressions results in less resistance for the composite material during flow mixing, making the mixing easier.

[0071]

Second Embodiment

[0072] Furthermore, a preparation method for preparing a babbit alloy composite material using the device of the above embodiment includes the following steps:

[0073] S100: Prepare a mixture of babbit alloy and reinforcing fibers;

[0074] S200: Add the mixture to the accommodating device 100, turn on the heating device 130, and control the temperature of the accommodating inner cavity 110 of the accommodating device 100 to reach T °C;

[0075] S300: Control the first punch 210 and the second punch 220 of the stamping device 200 to reciprocate alternately in the accommodating inner cavity 110 to stamp and mix the mixture in the accommodating device 100.

[0076] Specifically, the present invention provides a stamping and mixing method, which enables the reinforcing fibers to be evenly distributed in the babbit alloy, and the obtained composite material has uniform distribution of reinforcing fibers, high density of the composite material, and excellent comprehensive performance.

[0077] In this embodiment, S100 specifically includes:

[0078] S110: Process the babbit alloy into a plate;

[0079] S120: Uniformly lay the reinforcing fibers on the plate body;

[0080] S130: Stack the plate body and the reinforcing fibers alternately in the order of one layer of plate body and one layer of reinforcing fibers to obtain a stacked body;

[0081] S140: Press the stacked body to obtain a mixture, the pressing pressure is 100 Mpa, and the pressure holding time is 5 min.

[0082] Specifically, by using the method of layered and spaced stacking of the babbit alloy plate body and the reinforcing fibers, the reinforcing fibers have a relatively uniform initial value in the babbit alloy, thereby reducing the number of stamping processes, greatly improving the processing efficiency, and making the distribution of the reinforcing fibers in the composite material more uniform.

[0083] In this embodiment, S300 specifically includes:

[0084] S310: Control the first punch 210 to extrude the mixture, and after extrusion, control the first punch 210 to return. The extrusion speed of the first punch 210 is 20 mm / min;

[0085] S320: Control the second punch 220 to extrude the mixture, and after extrusion, control the second punch 220 to return. The extrusion speed of the second punch 220 is 20 mm / min;

[0086] S330: Repeat S310 and S320, and the number of repetitions is 150 - 170 times.

[0087] Specifically, by using the reciprocating and alternating movement of the first punch 210 and the second punch 220, the babbit alloy and the reinforcing fibers continuously move relative to each other, and finally reach a state where the reinforcing fibers are uniformly distributed in the babbit alloy.

[0088] In this embodiment, T is 110 - 130 °C.

[0089] Specifically, the babbit alloy has good plasticity and fluidity within this temperature range, which is beneficial to the full mixing of the babbit alloy and the reinforcing fibers; at the same time, it also reduces the stamping difficulty, reduces the stamping power consumption, and saves costs.

[0090] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
