Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a fire cover forming mould, a fire cover processing method and a fire cover. Background Art

[0002] As an important part of the stove, the fire cover is often used in conjunction with the fire distributor. There are multiple fire holes on the fire cover. Through the fire holes of different sizes on the fire cover, the size of the flame can be determined accordingly, thereby controlling the cooking speed and temperature of the food to achieve the ideal cooking effect.

[0003] However, currently, holes need to be punched in sequence on the fire cover to form the fire holes, which results in low processing efficiency of the fire cover. In addition, in order to ensure the regularity of the hole pattern of the fire holes, the fire holes can only be arranged on the side wall of the fire cover, which greatly affects the flame direction and heating efficiency of the fire cover. Summary of the invention

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a fire cover forming mold is provided, and the technical solution is as follows.

[0005] The fire cover forming mold includes a lower mold and an upper mold used to cover the lower mold. The upper mold has a lower surface facing the lower mold, and the lower surface is recessed in a direction away from the lower mold to form a die cavity. The lower mold has an upper surface facing the upper mold, and a protrusion protrudes from the upper surface. The protrusion has an inclined surface formed on one end away from the upper surface. When the upper mold moves along a first direction toward a direction close to the lower mold, the protrusion cooperates with the die cavity to form a die structure to apply a force to the fire cover to be formed.

[0006] In this way, a die structure can be formed by the mutual cooperation between the die cavity of the upper die and the raised portion of the lower die, and the fire cover to be formed can be formed by the die structure. And through the inclined surface of the raised portion, the fire outlet of the fire cover can be located on the outer edge of the arc of the fire cover. Therefore, when processing the fire cover, the hole can be punched first and then formed, and during the forming process, the position of the fire outlet can be ensured to be closer to the part to be heated, which greatly improves the processing efficiency and heating efficiency of the fire cover.

[0007] Exemplarily, the raised portion has a side wall surface connected to the inclined surface and connected to the upper surface, the side wall surface is perpendicular to the upper surface, and the inclined surface is inclined from the side wall surface in a direction away from the upper surface and toward the direction where the central area of ​​the raised portion is located. In this way, the raised portion can have a barrel-shaped side wall surface and an inclined surface connected to the side wall surface. By using the raised portion of the above shape, the fire cover after extrusion molding can have an arc-shaped area for setting the fire hole, and can also have a fixed area perpendicular to the upper surface. In this way, the fire cover can be firmly connected to the fire distributor and other components of the stove, effectively improving the practicality and reliability of the fire cover.

[0008] For example, a first positioning hole is provided on the upper mold, and a second positioning hole is provided on the lower mold. When the upper mold is covered with the lower mold, the center line of the first positioning hole and the center line of the second positioning hole meet the colinear condition. In this way, through the mutual cooperation between the first positioning hole and the second positioning hole, the accuracy of the positioning of the fire cover forming mold can be effectively improved, thereby improving the processing efficiency and yield rate of the fire cover.

[0009] According to another aspect of the present invention, a method for processing a fire cover is also provided, comprising the steps of: determining an outer edge position and a fire position on a metal plate; punching a hole perpendicular to the direction of the metal plate at the fire position to form a vertical hole; cutting the metal plate along the outer edge position to obtain a prefabricated plate body; and using a fire cover forming mold as described above to extrude the prefabricated plate body to form a fire cover; wherein, in the step of extruding the fire cover, the vertical hole on the prefabricated plate body is made to correspond to the inclined surface, so that the vertical hole is converted into a fire hole with an inclined angle through the inclined surface. In this way, the processing of the fire hole and the cutting of the prefabricated plate body can be completed quickly and efficiently. Using the fire cover forming mold, the prefabricated plate body to be formed can be processed into a fire cover, and the fire hole can be located in the direction corresponding to the inclined surface. As a result, the processing efficiency of the fire cover, as well as the heating efficiency and practicality of the fire cover are greatly improved.

[0010] Exemplarily, after the prefabricated plate is extruded and formed by the fire cover forming die, the method further comprises the steps of: punching a hole at the center of the fire cover to form a middle hole; and pressing edges on the sides of the middle hole to form the inner wall of the fire cover. In this way, the inner wall can be conveniently formed, and based on the setting of the inner wall, an air cavity can be effectively formed, which enhances the combustion efficiency and improves the overall structural strength and stability of the fire cover.

[0011] Exemplarily, after punching the fire outlet position, the method further comprises the step of: performing correction treatment on the fire outlet hole and the prefabricated plate body. In this way, performing correction treatment on the fire outlet hole and the prefabricated plate body can reduce damage to the fire cover, extend the service life of the fire cover, and effectively improve the quality of the fire cover.

[0012] Exemplarily, before the prefabricated plate is extruded by the fire cover forming die, the method further includes the step of: sandblasting the prefabricated plate. In this way, the sandblasting can be used to clean and remove dirt, oxides or scratches on the surface of the prefabricated plate, and the outer surface of the fire cover can also be polished, thereby further improving the quality of the outer surface of the fire cover and enhancing the corrosion resistance of the fire cover.

[0013] Exemplarily, after the prefabricated board is extruded by the fire cover forming mold, the method further includes: cleaning and treating the surface of the prefabricated board after extrusion. In this way, by cleaning and treating the surface of the prefabricated board after extrusion, the quality of the appearance of the fire cover can be effectively improved, and the service life and market competitiveness can be enhanced.

[0014] According to another aspect of the present invention, a fire cover is also provided, and the fire cover is made by the fire cover processing method as described above. The fire cover of the present invention is made by the fire cover processing method as described above, and since the fire cover processing method as described above has the beneficial effects as described above, the fire cover made by the fire cover processing method as described above must also have the beneficial effects as described above.

[0015] Exemplarily, the fire cover has a top wall, a peripheral side wall and an inclined wall, the inclined wall is connected between the top wall and the peripheral side wall, and the fire outlet is located on the inclined wall. In this way, the position of the fire outlet can be closer to the part to be heated, so that the flame ejected from the fire outlet can directly act on the part to be heated, effectively improving the heating efficiency of the fire cover and reducing fuel consumption.

[0016] Exemplarily, the fire cover is made of stainless steel material. Since the stainless steel material has strong stability and corrosion resistance, the practicality and durability of the fire cover are effectively improved.

[0017] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented according to the contents of the specification.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present invention more obvious, the exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the protection scope of the present invention.

[0029] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0030] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0031] In one embodiment of the present invention, a fire cover forming mold 1 is provided, and the fire cover forming mold 1 can be used for processing and manufacturing a fire cover. The fire cover forming mold 1 of an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Combined with reference Figure 1 and Figure 2 The fire cover forming mold 1 includes a lower mold 12 and an upper mold 11 for covering the lower mold 12. The upper mold 11 has a lower surface 111 facing the lower mold 12, and a die cavity 112 is formed on the lower surface 111 in a direction away from the lower mold 12. The lower mold 12 has an upper surface 121 facing the upper mold 11, and a protrusion 122 protrudes from the upper surface 121. The protrusion 122 is formed with an inclined surface 1221 on one end away from the upper surface 121, and when the upper mold 11 moves along the first direction toward the lower mold 12, the protrusion 122 cooperates with the die cavity 112 to form a die structure to apply a force to the fire cover to be formed.

[0033] The fire cover forming mold 1 can be used to process and manufacture a fire cover, which has fire outlet holes 41 arranged along a ring. The fire cover can heat food more evenly, prevent the flame from directly contacting the food, and effectively avoid the situation where the food is partially overheated and burnt. In addition, the size and temperature of the flame can be controlled by replacing the fire cover with fire outlet holes 41 of different aperture sizes to meet different cooking needs.

[0034] The lower mold 12 and the upper mold 11 of the fire cover forming mold 1 are arranged correspondingly. The lower surface 111 of the upper mold 11 has an inwardly recessed die cavity 112, and the lower mold 12 is provided with a protrusion 122 adapted to the die cavity 112. Through the mutual engagement between the upper mold 11 and the lower mold 12, a die structure can be formed between the die cavity 112 and the protrusion 122.

[0035] The shape of the fire cover to be formed can be plate-shaped. The fire cover to be formed is set in the die structure, and through the extrusion of the die structure, the fire cover to be formed can be deformed by force and the forming of the fire cover can be completed.

[0036] The first direction can be represented as the direction in which the upper mold 11 approaches the lower mold 12. Figure 1 , the lower mold 12 is arranged in the horizontal direction, and the upper mold 11 moves toward the lower mold 12 in the vertical direction. Thus, the first direction can be expressed as the direction of the Z axis in the Cartesian coordinate system, such as Figure 3 As shown, when the upper surface 121 is a plane, the first direction may be perpendicular to the upper surface 121 .

[0037] The inclined surface 1221 is arranged on one end of the raised portion 122 away from the upper surface 121. When a force is applied to the fire cover to be formed through the fire cover forming mold 1, the outer edge 2 of the processed fire cover can be made arc-shaped, and the fire hole 41 can be located on the arc-shaped outer edge 2, thereby, the position of the fire hole 41 can be closer to the food to be heated.

[0038] In the above embodiment, a die structure can be formed by the mutual cooperation between the die cavity 112 of the upper die 11 and the raised portion 122 of the lower die 12, and the fire cover to be formed is extruded by the die structure to complete the forming of the fire cover. And through the inclined surface 1221 of the raised portion 122, the fire outlet 41 of the fire cover can be located on the arc-shaped outer edge 2 of the fire cover, so that when processing the fire cover, the hole can be punched first and then formed, and during the forming process, it is ensured that the position of the fire outlet 41 is closer to the part to be heated, which greatly improves the processing efficiency and heating efficiency of the fire cover.

[0039] In some embodiments, see Figure 3 The protrusion 122 has a side wall surface 1222 connected to the inclined surface 1221 and connected to the upper surface 121, the side wall surface 1222 is perpendicular to the upper surface 121, and the inclined surface 1221 is inclined from the side wall surface 1222 in a direction away from the upper surface 121 and toward the center area of ​​the protrusion 122.

[0040] In the above embodiment, the raised portion 122 can have a barrel-shaped side wall surface 1222 and an inclined surface 1221 connected to the side wall surface 1222. By utilizing the raised portion 122 of the above shape, the fire cover after extrusion can have an arc-shaped area for setting the fire hole 41, and can also have a fixed area perpendicular to the upper surface 121. In this way, the fire cover can be firmly connected to the fire divider and other components of the stove, effectively improving the practicality and reliability of the fire cover.

[0041] In some embodiments, in conjunction with Figure 1 and Figure 2 A first positioning hole 113 is provided on the upper mold 11, and a second positioning hole 123 is provided on the lower mold 12. When the upper mold 11 covers the lower mold 12, the center line of the first positioning hole 113 and the center line of the second positioning hole 123 meet the colinear condition.

[0042] The first positioning hole 113 and the second positioning hole 123 can be through holes respectively. When the upper mold 11 and the lower mold 12 are buckled together, the center line of the first positioning hole 113 and the center line of the second positioning hole 123 overlap and are located in a straight line, thereby ensuring the accuracy of the position of the upper mold 11 and the lower mold 12 when they are buckled together.

[0043] Optionally, there may be plural first positioning holes 113 and plural second positioning holes 123 , respectively. Thus, when the plural first positioning holes 113 and the plural second positioning holes 123 corresponding thereto satisfy the co-linear condition, the positioning accuracy of the fire cover forming mold 1 can be further determined.

[0044] Alternatively, one of the upper mold 11 and the lower mold 12 may be provided with a boss, and the other of the upper mold 11 and the lower mold 12 may be provided with a groove, and the positions of the upper mold 11 and the lower mold 12 may be accurately determined by the cooperation between the boss and the groove.

[0045] In the above embodiment, the first positioning hole 113 and the second positioning hole 123 cooperate with each other, so as to effectively improve the positioning accuracy of the fire cover forming mold 1, thereby improving the processing efficiency and yield rate of the fire cover.

[0046] In one embodiment of the present invention, a method for processing a fire cover is also provided. Figure 4 , including steps S101 to S104.

[0047] Step S101: Determine the position of the outer edge 2 and the ignition position on the metal plate 4.

[0048] The metal plate 4 can be represented as the raw material of the fire cover to be formed, and the ignition position can be represented as the position of the ignition hole 41. By determining the position of the outer edge 2 and the ignition position on the metal plate 4, the general outline of the fire cover to be formed and the position of the ignition hole 41 can be determined.

[0049] See also Figure 5 There are multiple fire holes 41, which are arranged in a ring shape on the metal plate 4 to form two fire outlet channels, and the two fire outlet channels are sequentially arranged, and one of the fire outlet channels is arranged near the outer edge 2 of the fire cover to be formed.

[0050] Step S102: punching a hole in a direction perpendicular to the metal plate 4 at the firing position to form a vertical hole.

[0051] Punching is a method of metal processing. By punching, a plurality of holes can be formed quickly and synchronously on the metal plate 4, and the size and position of the holes can be precisely controlled.

[0052] The vertical hole can be understood as the axis of the fire hole 41 formed after punching is perpendicular to the direction of the plane of the metal plate 4. By punching, a vertical hole can be formed on the metal plate 4 in the vertical direction, thereby completing the processing of the fire hole 41 quickly and efficiently, reducing the processing difficulty of the fire hole 41, and ensuring the quality of the fire hole 41.

[0053] Step S103: cutting the metal plate 4 along the outer edge 2 to obtain a prefabricated plate body.

[0054] Step S104: using the fire cover forming mold 1 as described above to extrude a fire cover on the prefabricated plate; wherein, in the step of extruding the fire cover, the vertical hole on the prefabricated plate is made to correspond to the inclined surface 1221, so that the vertical hole is converted into a fire hole 41 with an inclined angle through the inclined surface 1221.

[0055] By using the fire cover forming die 1, the cut prefabricated plate can be made into a fire cover through an extrusion process.

[0056] The fire hole 41 with an inclined angle can be understood as having an inclined angle between the axis of the fire hole 41 and the direction where the plane of the metal plate 4 is located, and the axis of the fire hole 41 is inclined toward the direction where the central area of ​​the protrusion 122 is located.

[0057] In the above-mentioned fire cover processing method embodiment, the processing of the fire outlet hole 41 and the cutting of the prefabricated plate body can be completed quickly and efficiently. The prefabricated plate body to be formed can be processed into a fire cover by using the fire cover forming mold 1, and the fire outlet hole 41 can be located in the direction corresponding to the inclined surface 1221. Therefore, the processing efficiency of the fire cover, as well as the heating efficiency and practicality of the fire cover are greatly improved.

[0058] In some embodiments, after the prefabricated plate is extruded by the fire cover forming mold 1, the method further includes the steps of: punching a hole in the center of the fire cover to form a middle hole 3; and pressing edges on the sides of the middle hole 3 to form an inner wall 5 of the fire cover.

[0059] Combined with reference Figure 6 and Figure 7 A hole is punched at the center of the upper surface 121 of the fire cover to form a middle hole 3. By applying a force on the side of the middle hole 3, the above-mentioned position is bent toward the plane where the metal plate 4 is located after being subjected to the force to form the inner circle wall 5 of the fire cover.

[0060] The inner wall 5 of the fire cover can increase the heat dissipation surface area of ​​the fire cover, promote the conduction and dissipation of heat, and can also be provided with a ring-shaped support structure in the fire cover to prevent the fire cover from deforming or deforming during use, thereby ensuring the shape and function of the fire cover. In addition, an air cavity can be formed in the fire cover through the inner wall 5, and the air cavity can promote the flow of air, making it easier for fuel to mix with air, effectively improving the combustion efficiency and reducing fuel consumption.

[0061] In the above embodiment, the inner ring wall 5 can be conveniently formed, and based on the setting of the inner ring wall 5, an air cavity can be effectively formed, thereby enhancing the combustion efficiency and improving the overall structural strength and stability of the fire cover.

[0062] In some embodiments, after punching holes at the ignition position, the method further includes the step of: performing correction treatment on the ignition hole 41 and the prefabricated plate body.

[0063] After the punching operation is completed, the quality of the fire hole 41 and the prefabricated plate can be checked and corrected to ensure that the edge of the fire hole 41 is clean and burr-free, and the prefabricated plate is flat. When the above problems occur, they can be corrected by a leveling machine or manual grinding.

[0064] In the above embodiment, the fire outlet hole 41 and the prefabricated plate are corrected to reduce damage to the fire cover, extend the service life of the fire cover, and effectively improve the quality of the fire cover.

[0065] In some embodiments, before the prefabricated panel is extruded and formed by the fire cover forming mold 1, the method further includes the step of: sandblasting the prefabricated panel.

[0066] In the above embodiment, sandblasting can be used to clean and remove dirt, oxides or scratches on the surface of the prefabricated board, and the outer surface of the fire cover can also be polished, thereby further improving the quality of the outer surface of the fire cover and enhancing the corrosion resistance of the fire cover.

[0067] In some embodiments, after the prefabricated board is extruded and formed by using the fire cover forming mold 1, the method further includes: cleaning and treating the surface of the prefabricated board after extrusion forming.

[0068] After the fire cover is formed by extruding the prefabricated plate body using the fire cover forming mold 1, the fire cover can be cleaned and subjected to necessary surface treatment to remove impurities such as oil stains and dust on the surface of the fire cover.

[0069] In the above embodiment, by cleaning and treating the surface of the prefabricated plate body after extrusion molding, the appearance quality of the fire cover can be effectively improved, and the service life and market competitiveness can be enhanced.

[0070] In one embodiment of the present invention, a fire cover is further provided. The fire cover is manufactured by the fire cover processing method as described above.

[0071] The fire cover of the present invention is manufactured using the fire cover processing method as described above. Since the fire cover processing method as described above has the beneficial effects as described above, the fire cover manufactured using the fire cover processing method as described above must also have the beneficial effects as described above.

[0072] In some embodiments, the fire cover has a top wall 6 , a peripheral side wall 7 and an inclined wall 8 , the inclined wall 8 is connected between the top wall 6 and the peripheral side wall 7 , and the fire outlet 41 is located on the inclined wall 8 .

[0073] In the above embodiment, the position of the fire hole 41 can be made closer to the part to be heated, so that the flame ejected from the fire hole 41 can directly act on the part to be heated, effectively improving the heating efficiency of the fire cover and reducing fuel consumption.

[0074] In some embodiments, the fire cover is made of a stainless steel material.

[0075] Stainless steel material can withstand high temperatures and the pressure caused by daily use, avoiding deformation or damage of the fire cover and effectively improving the structural strength of the fire cover.

[0076] Stainless steel is also highly resistant to corrosion, allowing the fire cover to maintain its appearance and performance when in a humid environment or in contact with food, making it less likely to rust or breed bacteria.

[0077] In the above embodiment, since the stainless steel material has strong stability and corrosion resistance, the practicality and durability of the fire cover are effectively improved.
