Description

Technical field:

[0002] The invention belongs to the technical field of water tanks, and in particular relates to a water tank assembly plate and a production process thereof. Background technology:

[0004] Water tanks are widely used in life, production, fire protection and other fields, among which stainless steel water tanks are a more commonly used type of water tank. Existing stainless steel water tanks are assembled from several stainless steel plates, which are connected by bolts or fixed by welding. When the stainless steel plates are connected by bolts, the adjacent stainless steel plates are sealed by rubber strips. This structure is prone to reduced waterproof effect after long-term use, causing leakage. At the same time, the paint on the surface of the stainless steel plate is easily scratched when the bolts are tightened, making the stainless steel plate prone to rust. When the stainless steel plate is fixed by welding, professional welders are required to perform welding operations using welding equipment during on-site welding, and the welding accuracy requirements are high. Not only is the operation cumbersome, the installation cost is high, but also the subsequent maintenance is inconvenient. Summary of the invention:

[0006] The present invention makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a water tank assembly plate and a production process thereof, which is not only easy to install and maintain but also has a good sealing effect.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a water tank assembly plate, comprising an assembly plate body with folded edges on all four edges, a covering layer is provided on the outer side of the assembly plate body, and the surrounding edges of the covering layer are provided with covering edges corresponding to the folded edge positions of the surrounding edges of the assembly plate body, the covering edges wrap the folded edges corresponding to the positions, a sealing layer is provided on the outer side of the covering edges, and a plurality of connecting holes are provided between the sealing layer, the covering edges and the folded edges.

[0010] Furthermore, the outer side surface of the covering edge is provided with a groove penetrating along the length direction thereof, the sealing layer is of the same length as the groove, and one end of the sealing layer is embedded in the groove.

[0011] Furthermore, the coating layer is made of plastic material, and the coating layer is high-pressure injection-molded on the assembly board body.

[0012] Furthermore, the sealing layer is made of silicone material, and the sealing layer and the covering edge are compositely molded.

[0013] Furthermore, the folded edge is perpendicular to the assembly board body.

[0014] Furthermore, a plurality of connection holes are spaced apart and distributed along the length direction of the folded edge, and positioning pin holes are respectively provided at both ends of the sealing layer, the covering edge and the folded edge.

[0015] Furthermore, the assembly plate body is made of metal and is rectangular in shape, and the shape of the coating layer is adapted to the shape of the assembly plate body.

[0016] Another technical solution adopted by the present invention is: a production process of a water tank assembly plate, comprising the following steps:

[0017] Step S1: The assembly board body is punched and formed, and folded edges are formed on the four edges of the assembly board body;

[0034] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] like Figures 1 to 7 As shown, a water tank assembly plate of the present invention comprises a rectangular assembly plate body 1 with folded edges 2 arranged on the four edges, a coating layer 3 of plastic material arranged on the outside of the assembly plate body 1, a coating edge 4 corresponding to the position of the folded edges 2 on the four edges of the assembly plate body 1 arranged on the four edges of the coating layer 3, the coating edge 4 enveloping the folded edges 2 at the corresponding positions, a sealing layer 5 of silicone material arranged on the outside of the coating edge 4, and a plurality of connection holes 6 arranged between the sealing layer 5, the coating edge 4 and the folded edges 2. The assembly plate body, the coating layer of plastic material and the sealing layer of silicone material are formed into a whole, and when adjacent assembly plates are spliced, the sealing layers are in contact with each other so that the gap has a good sealing effect, which not only realizes the water sealing of the water tank, but also has good assembly accuracy, and at the same time, the assembly plate can be fastened and fixed by bolts passing through the connection holes, which is convenient for assembly and later maintenance.

[0037] In this embodiment, in order to achieve a good covering effect on the folded edge, the covering edge 4 is in a U-shape with its opening facing the assembly board body 1, the folded edge 2 is located inside the covering edge 4, and the inner and outer side walls of the folded edge 2 are respectively in contact with the two inner side surfaces of the covering edge 4. The covering edge of the plastic material completely covers the folded edge of the assembly board body, which not only provides a good protection effect on the folded edge to prevent the paint on the surface of the folded edge from being worn away when tightening the bolts, thereby causing the folded edge to rust, but also improves the tightness of the connection between the covering layer and the assembly board body, ensuring that the two are formed into an integrated structure.

[0038] In this embodiment, in order to further improve the covering effect, the inner side edge of the covering edge 4 is vertically provided with a pressing edge 7 at one end close to the assembly board body 1, and the pressing edge 7 is in contact with the inner side surface of the assembly board body 1 to completely cover the folded edge 2.

[0039] In this embodiment, the outer side surface of the covering edge 4 is provided with a groove 8 that penetrates along its length direction, and the groove is rectangular, that is, the grooves on the covering edge around the covering layer are connected and are in the shape of a rectangular ring; the sealing layer 5 is the same length as the groove 8, and one end of the sealing layer 5 is embedded in the groove 8, that is, the sealing layer around forms a rectangular ring structure, ensuring that when the assembly board is spliced ​​from any side of the four sides, under the locking force of the bolts passing through the connecting holes, the sealing layers of the two assembly boards are tightly fitted, so that the gap between adjacent assembly boards has a good sealing effect, thereby ensuring the water sealing of the water tank.

[0040] In this embodiment, the coating layer 3 can be made of PE material, and the coating layer 3 is high-pressure injection-molded on the assembly board body 1. It should be noted that the high-pressure injection molding technology is a prior art, and its principle will not be repeated here.

[0041] In this embodiment, the sealing layer 5 is made of food grade silicone, and the sealing layer 5 and the covering edge 4 are compositely molded of silicone. It should be noted that the silicone composite molding technology is a prior art, and its principle will not be repeated here.

[0042] In this embodiment, the folded edge 2 is perpendicular to the assembly board body 1 and is also a rectangular structure; the covering edge 4 is also perpendicular to the covering layer 3.

[0043] In this embodiment, a plurality of connection holes 6 are spaced apart along the length direction of the folded edge 2, and positioning pin holes 9 are respectively provided at both ends of the sealing layer 5, the covering edge 4 and the folded edge 2. When the two assembly boards are assembled, positioning pins are first inserted into the positioning pin holes 9 at both ends, and then bolts are passed through the connection holes 6 to achieve locking.

[0044] In this embodiment, the assembly board body 1 is made of metal, such as iron plate, stainless steel plate, etc., and the assembly board body 1 is formed by stamping; the shape of the coating layer 3 is adapted to the shape of the assembly board body 1 so as to have a good coating effect.

[0045] In this embodiment, the production process of the water tank assembly plate includes the following steps:

[0046] Step S1: a rectangular metal assembly plate body 1 is stamped on a stamping device, and folded edges 2 are formed on the edges of the assembly plate body 1, and the folded edges 2 are perpendicular to the assembly plate body 1;

[0047] Step S2: drilling a connection hole 6 and a positioning pin hole 9 on the folded edge 2 by means of a drilling device;

[0048] Step S3: placing the assembled body 1 after drilling in step S2 on the injection mold, and the injection mold high-pressure injection molding a covering layer 3 of plastic material on the outer side of the assembled board body 1, and the covering edge 4 around the covering layer 3 covers the folding edge 2, and the covering edge 4 has a hole position corresponding to the position of the connection hole and the positioning pin hole on the folding edge 2, and the outer side of the covering edge 4 has a groove 8, and the pressing edge 7 at one end of the covering edge 4 is pressed on the inner side of the assembled board body 1, so that the assembled board body 1 and the covering layer 3 form a whole;

[0049] Step S4: A sealing layer 5 made of silicone material is compositely molded in the groove 8 on the outer side of the coating edge 4. After molding, the sealing layer 5 also has hole positions corresponding to the connection holes 6 and the positioning pin holes 9 on the folded edge. The sealing layer 5 and the coating layer 3 form a whole, and finally the metal assembly board body 1, the plastic coating layer 3 and the silicone sealing layer 5 form a whole.

[0050] The advantages of the present invention are:

[0051] (1) The metal assembly board body, the plastic coating layer and the silicone sealing layer form a whole, which not only has good structural strength, but also the entire assembly board is not easy to shift when tightened with bolts, ensuring good assembly accuracy. This overcomes the problem that the sealing strip in traditional technology is easy to shift when tightened with bolts, resulting in unsatisfactory sealing effect;

[0052] (2) There is a sealing layer of silicone material on the sides of the assembly board. When the two assembly boards are locked by bolts, the sealing layers of the two assembly boards will fit tightly under the action of the bolt locking force, ensuring that the assembly gap has a good sealing effect and achieving good water sealing of the water tank. Compared with the traditional sealing method using rubber strips or welding, it has better sealing, longer service life, is not easy to damage, and is easy to maintain and replace;

[0053] (3) When assembling the assembly panels, there is no need for welding, only bolts need to be tightened. The assembly is simple and convenient, and requires low professional skills of workers. Ordinary workers can complete the assembly, which greatly reduces the installation cost, improves the assembly efficiency, and also facilitates later maintenance.

[0054] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integrated molding using a casting process) (except when it is obviously impossible to use an integrated molding process).

[0055] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the present invention include states or shapes that are approximate, similar, or close to them.

[0056] Any component provided by the present invention may be assembled from a plurality of separate components, or may be a separate component manufactured by an integral forming process.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
