Description

Technical Field

[0001] This utility model relates to the field of pre-coated steel plate technology, and in particular to a mechanically embossed pre-coated steel plate for refrigerators. Background Technology

[0002] Pre-coated steel sheet is a type of steel sheet with one or more layers of organic coating pre-coated on its surface. It is usually made of cold-rolled steel sheet or hot-dip galvanized sheet as the base material, and is a metal material that is coated with organic coating after surface treatment. The manufacturing process of this material includes steps such as cold rolling or hot-dip galvanizing, surface pretreatment, coating and baking. Among them, surface pretreatment is particularly critical, including cleaning, scratching, passivation, etc., to ensure the adhesion and corrosion resistance of the coating.

[0003] Mechanically embossed pre-coated steel sheets for refrigerators are a specially designed metal material widely used in the manufacture of refrigerator shells and other home appliance components. Through mechanical embossing and pre-coating of a protective layer on the surface, these steel sheets possess a variety of superior properties, meeting the home appliance industry's requirements for aesthetics, durability, and functionality.

[0004] A type of mechanically embossed pre-coated steel sheet used in refrigerators has the following drawbacks:

[0005] 1) Existing pre-coated steel plates can only deform within a limited space during embossing, which makes it very easy for local material accumulation or insufficient material to occur. However, this will lead to uneven material flow during the embossing process, increasing the difficulty of forming and making it difficult to achieve the expected shape and depth of embossing. Especially for complex embossing shapes, it may not be possible to form a complete and clear shape. At the same time, due to the poor material flow, greater pressure and longer time are required to complete the embossing, which will reduce the production efficiency of embossing and increase the production cost. Utility Model Content

[0006] This invention proposes a honeycomb micro-elastic enhanced embossing component. The honeycomb pores provide additional space for material flow in the steel plate during the embossing process. When the mold applies pressure to the steel plate, the material can flow into the pores, thereby avoiding excessive accumulation or insufficient material in local areas. This results in a more uniform material distribution at the embossing point, which is conducive to forming complete and clear embossing. Furthermore, the micro-spring structure can be finely adjusted according to the pressure changes during the embossing process, thus effectively solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a mechanically embossed pre-coated steel plate for refrigerators, comprising a honeycomb micro-elasticity enhanced embossing component and a main steel plate, wherein the honeycomb micro-elasticity enhanced embossing component is installed on one side of the outer wall of the main steel plate;

[0008] The honeycomb micro-elasticity enhanced embossing component includes a middle steel plate, the interior of which is provided with a set of honeycomb-shaped pores. These pores provide material flow space during the embossing process. A set of micro-springs is fixedly connected to the outer wall of the middle steel plate. These micro-springs are used to adjust the pressure distribution through their own elastic deformation.

[0009] Preferably, the outer wall of the middle steel plate is elastically connected to four connecting springs, and one end of the outer wall of each of the four connecting springs is elastically connected to a supporting steel plate.

[0010] Preferably, the outer wall of the main steel plate is connected to a set of micro springs.

[0011] Preferably, a set of reinforcing ribs are fixedly connected to the outer wall of the supporting steel plate.

[0012] Preferably, the reinforcing ribs are distributed in multiple strips to improve the structural strength of the steel plate.

[0013] Preferably, a set of reinforcing ribs has a reinforcing steel plate fixedly connected to its outer surface.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, a honeycomb micro-elastic enhanced embossing component is provided. The honeycomb pores provide additional space for material flow in the steel plate during the embossing process. When the mold applies pressure to the steel plate, the material can flow into the pores, thereby avoiding excessive accumulation or insufficient material in local areas. This makes the material distribution at the embossing point more uniform, which is conducive to forming complete and clear embossing. Furthermore, the micro-spring structure can be finely adjusted according to the pressure changes during the embossing process. During embossing, the pressure of the mold on the steel plate is not completely uniform. The micro-spring can be compressed in areas of higher pressure and extended in areas of lower pressure, thereby making the pressure on the surface of the steel plate more uniform, improving the accuracy and consistency of the embossing, and thus ensuring that the dimensional parameters such as the depth and width of the embossing are more stable.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, according to Figures 1-4 As shown, this utility model provides a technical solution: a mechanically embossed pre-coated steel plate for refrigerators, including a honeycomb micro-elasticity enhanced embossing component 2 and a main steel plate 1, wherein the honeycomb micro-elasticity enhanced embossing component 2 is installed on one side of the outer wall of the main steel plate 1;

[0025] The honeycomb micro-elasticity enhanced embossing component 2 includes a middle steel plate 201. The middle steel plate 201 has a set of honeycomb-shaped pores 202 inside. The set of honeycomb-shaped pores 202 provides material flow space during the embossing process. A set of micro springs 203 are fixedly connected to the outer wall of the middle steel plate 201. The set of micro springs 203 is used to adjust the pressure distribution through its own elastic deformation.

[0026] The overall effect achieved by embodiment 1 is as follows: By pre-setting the above components, a complete honeycomb micro-elasticity enhanced embossing component 2 is formed. First, a set of honeycomb-shaped pores 202 are opened inside the middle layer steel plate 201. The set of honeycomb-shaped pores 202 provides material flow space during the embossing process. A set of micro-springs 203 are fixedly connected to the outer wall of the middle layer steel plate 201. The set of micro-springs 203 is used to adjust the pressure distribution through their own elastic deformation. The honeycomb-shaped pores 202 provide additional space for material flow in the steel plate during the embossing process. When the mold... When pressure is applied to the steel plate, the material can flow into the pores, thus avoiding excessive accumulation or insufficient material in local areas. This results in a more uniform material distribution at the embossing point, which is beneficial for forming complete and clear embossing. Furthermore, the micro-spring 203 structure can be finely adjusted according to the pressure changes during the embossing process. During embossing, the pressure of the mold on the steel plate is not completely uniform. The micro-spring 203 can compress in areas of higher pressure and extend in areas of lower pressure, thereby making the pressure on the surface of the steel plate more uniform, improving the accuracy and consistency of the embossing, and ensuring that the dimensional parameters such as the depth and width of the embossing are more stable.

[0027] Example 2, according to Figures 1-5 As shown, the outer wall of the middle steel plate 201 is elastically connected with four connecting springs 204, and one end of the outer wall of each of the four connecting springs 204 is elastically connected with a supporting steel plate 205. The outer wall of the main steel plate 1 is connected to a set of micro springs 203. The outer wall of the supporting steel plate 205 is fixedly connected with a set of reinforcing ribs 4. The reinforcing ribs 4 are distributed in multiple ways to improve the structural strength of the steel plate. The outer surface of each set of reinforcing ribs 4 is fixedly connected with a reinforcing steel plate 3.

[0028] The overall effect achieved by embodiment 2 is as follows: By pre-setting the above components, four connecting springs 204 are elastically connected to the outer wall of the middle steel plate 201. The springs have good elasticity and can absorb and dissipate energy through their own compression and extension when the steel plate is subjected to external impact. The connecting springs 204 at the four corners of the steel plate can effectively buffer the impact force from different directions, reduce the deformation and damage of the steel plate caused by vibration or collision, and improve the impact resistance of the steel plate. Furthermore, a set of reinforcing ribs 4 are fixedly connected to the outer wall of the supporting steel plate 205. The reinforcing ribs 4 are distributed in multiple ways to improve the structural strength of the steel plate. The reinforcing ribs 4 can increase the bending and torsional resistance of the steel plate, thereby improving the overall strength of the steel plate. When the steel plate is subjected to external force, the reinforcing ribs 4 can share some of the stress, delay the deformation and damage of the steel plate, and enable the steel plate to withstand greater loads.

[0029] The working principle of the entire equipment is as follows: During the installation stage, the components to be assembled are placed in a safe area to provide a safe assembly environment for subsequent assembly. First, the specific position of the main steel plate 1 is determined, and a set of honeycomb-shaped pores 202 are opened inside the middle steel plate 201. The set of honeycomb-shaped pores 202 provides material flow space during the embossing process. A set of micro springs 203 are fixedly connected to the outer wall of the middle steel plate 201, and the outer wall of the main steel plate 1 is connected to the set of micro springs 203. After the above components are installed, a complete honeycomb micro-elastic enhanced embossing component 2 is formed. Next, four connecting springs 204 are elastically connected to the outer wall of the middle steel plate 201, and a support steel plate 205 is elastically connected to one end of the outer wall of each of the four connecting springs 204. Then, a set of reinforcing ribs 4 are fixedly connected to the outer wall of the support steel plate 205, and a reinforcing steel plate 3 is fixedly connected to the outer surface of the set of reinforcing ribs 4.

[0030] The device operates as follows: After all components are assembled, check that each component is properly installed and secured, ensuring there are no loose parts. Once confirmed, place the steel plate to be embossed onto the feeding device of the embossing machine. The steel plate is accurately fed into the working area of ​​the embossing machine via a transmission mechanism. Start the embossing machine via an external power supply. The upper and lower pressure rollers drive the die to apply pressure to the steel plate. Under pressure, the pattern of the die is imprinted onto the surface of the steel plate, forming the corresponding embossing. During this process, a set of honeycomb pores 202 and a set of micro-springs 203 play a role. The honeycomb pores 202 provide additional space for material flow during the embossing process. When the die applies pressure to the steel plate, the material can flow into the pores, thus avoiding excessive or insufficient material accumulation in local areas, ensuring the material at the embossed area... The material distribution is more uniform, which is conducive to forming complete and clear embossing. Furthermore, the micro-spring 203 structure can be finely adjusted according to the pressure changes during the embossing process. During embossing, the pressure of the mold on the steel plate is not completely uniform. The micro-spring 203 can compress in areas with higher pressure and extend in areas with lower pressure, thereby making the pressure on the surface of the steel plate more uniform, improving the accuracy and consistency of the embossing, and ensuring that the dimensional parameters such as the depth and width of the embossing are more stable. In addition, due to the setting of the reinforcing ribs 4, multiple reinforcing ribs 4 are distributed to improve the structural strength of the steel plate. The reinforcing ribs 4 can increase the bending and torsional resistance of the steel plate, thereby improving the overall strength of the steel plate. When the steel plate is subjected to external forces, the reinforcing ribs 4 can share some of the stress, delay the deformation and failure of the steel plate, and enable the steel plate to withstand greater loads.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
