Description

Technical field

[0001] The present utility model relates to the technical field of solder coatings, in particular a device for producing a wear-resistant structured coating by soldering. State of the art

[0002] Currently, metallic wear-resistant composite coatings are products specifically designed for large-area wear applications. In this process, a coating of a specific thickness and high hardness is applied to the surface of a base material using a welding process to improve its wear resistance.

[0003] Soldering is a process for creating wear-resistant layers. There are two methods for producing wear-resistant coatings by soldering: The first method creates a continuous, full-surface wear-resistant coating area on the workpiece, but this method results in material waste. The second method involves first creating wear-resistant blocks, which are then bonded to the workpiece surface. Although this method can save material, the efficiency of the soldering process is extremely low. Furthermore, large-area coatings can easily lead to high frictional resistance on the work surface.Therefore, there is currently an urgent need for the development of a novel, efficient soldering process for the production of wear-resistant coatings that both reduces the waste of wear-resistant material and ensures that the produced coating is not only wear-resistant but also reduces frictional resistance on the work surface, among other things.

[0005] The present application provides a method for producing a wear-resistant structured coating by soldering, which serves to form a coating with a structure of convex and concave surfaces on a workpiece. The method for producing the wear-resistant structured coating by soldering comprises the following steps: Preheating areas of the workpiece that correspond to the convex surfaces in the intended coating; Applying a paste-like solder to the preheated areas of the workpiece; Shaping the paste-like solder on the workpiece using a mold; Heating the areas of the workpiece fitted with the mold; cooling and removal of the mold.

[0006] The above-mentioned technical solution further provides that the preheating of the areas of the workpiece corresponding to the convex surfaces in the intended coating is carried out by means of infrared heating.

[0007] In one of the above-mentioned technical solutions, it is further provided that during the application of the paste-like solder to the preheated areas of the workpiece, the ratio of binder metal to wear-resistant particles in the paste-like solder is adjusted so that the wetting angle is increased when the paste-like solder flows on the workpiece surface and a rounded transition of the coating is achieved.

[0008] In one of the aforementioned technical solutions, it is further provided that the heating of the areas of the workpiece equipped with the mold is carried out by means of electromagnetic induction heating.

[0009] The present application further provides a device for producing a wear-resistant structured coating by soldering, comprising: a box body, a shielding plate element and an infrared heating element arranged inside the box body, wherein the infrared heating element is arranged above the shielding plate element along the vertical direction of the box body and a receiving space for placing a workpiece is formed below the shielding plate element; wherein a transparent part and an opaque part are formed on the shielding plate element.

[0010] In the above-mentioned technical solution, it is further provided that the device for producing the wear-resistant structured coating by soldering includes a preheating storage box which is arranged in the receiving space of the box body, with several mounting positions on the box body for the preheating storage box being provided along the vertical direction of the box body.

[0011] In one of the aforementioned technical solutions, it is further provided that several openings are formed on a side part of the box body, arranged successively along the vertical direction of the box body, the openings serving for mounting the preheating storage box; wherein an auxiliary mounting plate element is arranged on each of the two opposite side parts of each opening, and the auxiliary mounting plate element is designed with a mounting through-opening; wherein a support component is arranged inside the box body below each of the openings; wherein the preheating storage box comprises a support plate element and a first closure plate element arranged on the support plate element; wherein a part of the support plate element passes through an opening in the box body and extends into the interior of the box body, and the first closure plate element covers the opening.

[0012] In one of the above-mentioned technical solutions, it is further provided that the remaining openings of the box body are each provided with a second closure plate element, which is successively guided through the through-openings of the auxiliary mounting plate elements on both sides of the corresponding opening; wherein the preheating storage box also includes a positioning plate element which is arranged on the side of the support plate element facing away from the first closure plate element; wherein the support plate element is a square plate element, wherein the positioning plate element has an L-shaped structure and the two parts of the positioning plate element are each arranged flush with the two corresponding adjacent sides of the support plate element.

[0013] In one of the above-mentioned technical solutions, it is further provided that the number of positioning plate elements is two, wherein the two positioning plate elements are spaced apart along the longitudinal direction of the support plate element; wherein the positioning angles formed by the two positioning plate elements themselves are arranged diagonally to each other.

[0014] In one of the above-mentioned technical solutions, it is further provided that the shielding plate element and the box body form a detachable connection structure by being plugged in.

[0015] In comparison to the prior art, the advantageous effects of the present application are as follows: The present method for producing a wear-resistant structured coating by soldering allows a coating with a structure of convex and concave surfaces to be formed on the surface of a workpiece. Specifically, by locally heating the workpiece surface, the wear-resistant material adheres more easily to the locally heated areas. The resulting coating in the heated areas is thicker than in the unheated areas, meaning that a coating with a structure of convex and concave surfaces is formed on the workpiece surface. The convex surfaces serve as wear-resistant surfaces, and the concave surfaces as substrate protection surfaces. Unlike conventional wear-resistant coatings, this coating features not only wear-resistant surfaces but also substrate protection surfaces.The convex surfaces ensure wear resistance while simultaneously reducing the contact area with the contacting material, thereby reducing the frictional force.

Furthermore, the terms "first", "second", and "third" are used for descriptive purposes only and are not to be understood as indicating or implicitly suggesting any relative significance.

[0023] In the description of the present application, it should be noted that the terms "attach," "connect," and "connect" are to be understood in a broad sense unless expressly stated otherwise and limited; for example, it may be a fixed, detachable, or integrated connection; a mechanical or electrical connection; a direct connection or an indirect connection via an intermediate medium; or a connection within two components. The specific meaning of the aforementioned terms in the present application can be understood by a person skilled in the art according to the specific circumstances.

[0024] The following will refer to Fig. 1 to 7 describe a method and a device for producing a wear-resistant structured coating by soldering according to some embodiments of the present application. Example I

[0025] The embodiments of the present application provide a method for producing a wear-resistant structured coating by soldering, which serves to form a coating with a structure of convex and concave surfaces on a workpiece. The method for producing the wear-resistant structured coating by soldering comprises the following steps: Preheating areas of the workpiece that correspond to the convex surfaces in the intended coating; Applying a paste-like solder to the preheated areas of the workpiece; Shaping the paste-like solder on the workpiece using a mold; Heating the areas of the workpiece that are fitted with the mold; Cool and remove the mold.

[0026] It is evident that this method for producing a wear-resistant structured coating by soldering onto the surface of a workpiece can create a coating with a structure of convex and concave surfaces. Specifically, by locally heating the workpiece surface, the wear-resistant material adheres more easily to the heated areas. The resulting coating in the heated areas is thicker than in the unheated areas, meaning that a coating with a structure of convex and concave surfaces is formed on the workpiece surface. The convex surfaces serve as wear-resistant areas, and the concave surfaces as substrate protection surfaces. Unlike conventional wear-resistant coatings, this coating features not only wear-resistant surfaces but also substrate protection surfaces.The convex surfaces ensure wear resistance while simultaneously reducing the contact area with the contacting material, thereby reducing the frictional force.

[0027] Furthermore, it should be noted that if the aforementioned coating is used as a movable friction surface, the wear-resistant coating can be designed according to the direction of movement in order to save wear-resistant material while maintaining the same working surface area.

[0028] In this embodiment, the areas of the workpiece that correspond to the convex surfaces in the intended coating are as shown in Fig. 1 to Fig. Figure 5 shows that the workpiece is preheated by means of an infrared heater. In particular, the local preheating is carried out using an infrared heating tube in combination with a shielding plate element 3, as described in the second embodiment. This means that the areas of the workpiece where convex coating surfaces are to be formed are heated by the translucent parts of the shielding component, while the areas of the workpiece where concave coating surfaces are to be formed are not heated by the shielding parts. It is evident that local heating can be achieved with this heating method.

[0029] In this embodiment, preferably during the application of the paste-like solder to the preheated areas of the workpiece, the ratio of binder metal to wear-resistant particles in the paste-like solder is adjusted so that the wetting angle is increased when the paste-like solder flows on the workpiece surface.

[0030] The above description shows that during the application of the paste-like solder to the preheated areas of the workpiece, the proportion of binding particles in the paste can be adjusted at any time, depending on the size of the wetting angle after the paste has flowed, in order to maximize the wetting angle. This ultimately results in more wear-resistant material adhering to the areas of the workpiece where a coating with convex surfaces is to be formed. This also leads to the formation of a coating with a pronounced structure of convex and concave surfaces and contributes to the formation of a circular arc transition.

[0031] Furthermore, the proportion of the binding metal is preferably in the range of 65% to 95%, so that the proportion can be regulated within this range.

[0032] In this embodiment, the heating of the areas of the workpiece equipped with the mold is preferably carried out by means of electromagnetic induction heating.

[0033] The above description shows that electromagnetic induction heating has high efficiency, saves working time and allows for complete drying of the coating. Example II

[0034] As in Fig. 1 to Fig. As shown in Figure 7, the second embodiment of the present application further provides a device for producing a wear-resistant structured coating by soldering, which is used in the method for producing a wear-resistant structured coating by soldering as described in the first embodiment and thus has all the advantageous technical effects of this manufacturing method, without repeating the same technical features and advantageous effects.

[0035] In this exemplary embodiment, the device for producing a wear-resistant structured coating by soldering preferably comprises, as shown in Fig. 1 to Fig. Figure 5 shows a box body 1, a shielding plate element 3, and an infrared heating element 2, which are arranged inside the box body 1, wherein along the vertical direction of the box body 1 the infrared heating element 2 is arranged above the shielding plate element 3, and below the shielding plate element 3 a receiving space for placing a workpiece is formed; wherein a light-transmitting part and an opaque part are formed on the shielding plate element 3.

[0036] The above description shows that the present device for producing a wear-resistant structured coating by soldering allows for local preheating of the workpiece surface. Specifically, the workpiece is placed in the receiving chamber of the box body 1, and the infrared heating element 2 is activated. The infrared rays emitted by the infrared heating element 2 pass through the transparent part of the shielding plate element 3 and irradiate a predetermined area on the workpiece to preheat it. The workpiece is then removed, and a paste-like solder is applied to the preheated areas. This is followed by shaping using a mold, after which the molded areas of the workpiece are heated. In particular, the workpiece with the mold can be placed in a soldering furnace for induction heating.Finally, the product is cooled and the mold is removed.

[0037] It is evident that the present device allows for local heating of the workpiece surface, enabling the wear-resistant material to adhere more easily to the locally heated areas. The resulting coating in the heated areas is thicker than in the unheated areas, meaning that a coating with a structure of concave and convex surfaces is formed on the workpiece surface.

[0038] The convex surfaces serve as wear-resistant areas, while the concave surfaces act as substrate protection surfaces. Unlike conventional wear-resistant coatings, this coating features not only wear-resistant surfaces but also substrate protection surfaces. The convex surfaces ensure wear resistance while simultaneously reducing the contact area with the material, thus reducing friction.

[0039] Furthermore, the infrared heating element 2 is preferably an infrared radiation lamp according to the prior art, comprising a lampshade and several infrared heating tubes arranged in the lampshade.

[0040] In this exemplary embodiment, the device for producing a wear-resistant structured coating by soldering preferably comprises, as shown in Fig. 1 to Fig. Figure 5 shows a preheating storage box 4, which is arranged in the receiving space of the box body 1, wherein several mounting positions are provided on the box body 1 for the preheating storage box 4 along the vertical direction of the box body 1.

[0041] The structure described above shows that the advantage of the multiple mounting positions of the preheating storage box 4 along the vertical direction of the box body 1 is that the distance between the workpiece located in the preheating storage box 4 and the infrared heating element 2 positioned above it can be adjusted as needed. This allows the degree of preheating to be controlled and thus the thickness of the convex and concave areas of the coating to be regulated.

[0042] Furthermore, preferably, as in Fig. 1, Fig. 2 and Fig. Figure 5 shows that several openings 13 are formed on a side part of the box body 1, namely on a first side part, wherein the several openings 13 are arranged successively along the vertical direction of the box body 1. The openings 13 serve for mounting the preheating storage box 4, wherein these openings 13 are preferably designed as rectangular openings 13.

[0043] An auxiliary mounting plate element 6 is arranged on each of the two opposite side parts of each of the openings 13, and the auxiliary mounting plate element 6 is designed with a mounting through-opening 61. Preferably, this auxiliary mounting plate element 6 can extend along the vertical direction of the box body 1.

[0044] The preheating storage box 4 comprises a support plate element 41 and a first closure plate element 42 arranged on the support plate element 41, wherein a portion of the support plate element 41 extends through an opening 13 in the box body 1 and into the interior of the box body 1, and the first closure plate element 42 covers the opening 13. It is evident that the support plate element 41 serves to hold the workpiece, while the first closure plate element 42 serves to close this opening 13 in order to prevent the escape of infrared radiation, thereby improving the preheating effect.

[0045] Furthermore, a flanged edge is formed on the perimeter of the support plate element 41 located outside the box body 1. This flange facilitates gripping by an operator, thereby simplifying the pushing and pulling of the preheating storage box 4 and thus simplifying the installation of the preheating storage box 4 into or removal from the box body 1. The first closure plate element 42 is preferably a square plate element.

[0046] To ensure the stability of the mounting of the preheating storage box 4 on the box body 1, a support component, such as a support beam 14, can be arranged below each of the openings 13 inside the box body 1. The support beam 14 can support the preheating storage box 4; that is, when the preheating storage box 4 is inserted into the box body 1, it is located directly above the support beam 14. Of course, the structure of the support component is not limited to the support beam 14, but can also be designed as a support plate or another type of support structure.

[0047] The remaining openings 13 of the box body 1 are each provided with a second closure plate element 5, wherein the second closure plate element 5 is successively guided through the through-openings of the auxiliary mounting plate elements 6 on both sides of the respective opening 13. It can be seen that the second closure plate element 5 and the auxiliary mounting plate elements 6 are connected to each other by insertion, which corresponds to a detachable connection structure. This allows the positions of the preheating storage box 4 and the second closure plate element 5 to be interchanged as desired, thereby allowing the position of the preheating storage box 4 to be adjusted. Preferably, the second closure plate element 5 is a square plate element, with one side of the second closure plate element 5 forming a boundary section by bending.When the second closure plate element 5 is inserted into the auxiliary mounting plate elements 6, the limiting section is positioned directly against one of the auxiliary mounting plate elements 6 and serves to limit the second closure plate element 5.

[0048] The structure described above shows that the preheating storage box 4 can be inserted into one of the openings 13 as required, while the remaining openings 13 are closed with the second closing plate element 5 to prevent the escape of infrared radiation and to improve the preheating effect.

[0049] Furthermore, the preheating storage box includes 4, as shown in Fig. 6 and Fig. Figure 7 shows, preferably two positioning plate elements. These two positioning plate elements are arranged at intervals along the longitudinal direction of the support plate element 41. For better differentiation, they are referred to as the first positioning plate element 43 and the second positioning plate element 44. The support plate element 41 is a square plate element. The first positioning plate element 43 is arranged close to the first closure plate element 42 and can form a unit with the first closure plate element 42;

[0050] The second positioning plate element 44 is arranged on the side of the support plate element 41 facing away from the first closure plate element 42. Both the first positioning plate element 43 and the second positioning plate element 44 have an L-shaped structure, and the two structural parts of the second positioning plate element 44 are flush with the two corresponding adjacent sides of the support plate element 41. The positioning angles formed by the first positioning plate element 43 and the second positioning plate element 44 themselves are arranged diagonally to each other.

[0051] It should be noted that a third, vertical positioning plate element 45 can also be arranged on the second positioning plate element 44, with the two forming a single unit. If the third positioning plate element 45 rests against the inner wall of a second side panel of the box body 1, this indicates that the preheating storage box 4 is properly installed.

[0052] The structure described above shows that by inserting two opposite corners of the workpiece into the positioning angles of the two positioning components, the workpiece is positioned. Furthermore, if the shielding plate element 3 rests against the inner wall of the second side panel of the box body 1, the positioning of the shielding plate element 3 is also achieved. In this way, by providing translucent and opaque parts at predetermined positions of the shielding plate element 3, the concave and convex positions of the coating on the workpiece can be controlled.

[0053] It should be noted that the number of positioning plate elements is not limited to the description above, but can also be just one; that is, the first positioning plate element 43 mentioned above can be removed and the second positioning plate element 44 retained to also achieve a positioning function. The advantage here is that the other side is unlimited and the workpiece length can be arbitrary.

[0054] Furthermore, the support plate element 41, the first closure plate element 42, and the positioning plate elements can preferably be connected to each other by welding. Of course, this is not limited to welding; they can also be connected to each other by bonding, screws, or similar structures.

[0055] In this embodiment, as in Fig. 4 shown, to ensure the stability of the box body 1, preferably a reinforcing hollow tube element is arranged in the box body 1, which is connected to the box body 1 and serves to increase the strength and stability of the box body 1.

[0056] In this embodiment, as described in Fig. 1 and Fig. 4 shown, the box body 1 preferably comprises a main box body 11 and a top cover 12, wherein the top cover 12 is rotatably connected to the main box body 11 so that the box body 1 can be opened or closed as required, which facilitates subsequent maintenance work and other operations.

[0057] The top cover 12 has a square, cap-like structure that is hollow inside and has an opening 13 on its underside. The infrared heating element 2 is arranged on the upper part of the top cover 12.

[0058] The shielding plate element 3 is inserted into the top cover 12. It can be seen that the shielding plate element 3 and the top cover 12 form a detachable connection structure, which allows the shielding component to be easily exchanged with different structures depending on the coating to be formed, thus ensuring greater practicality.

[0059] Finally, it should be noted that the above embodiments serve only to illustrate the technical solutions of the present application, not to limit them; although the present application is described in detail with reference to the above embodiments, the person skilled in the art should understand that it is still possible to modify the technical solutions recorded in the above embodiments or to make equivalent replacements for some or all of their technical features; and these modifications or replacements do not deviate from the scope of the corresponding technical solutions of the various embodiments of the present application.
