Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of metal stamping, specifically relating to a riveting mold for oven burners. Background Technology
[0002] The oven grill burner is one of the core functional components of an oven. (See also:) Figure 1 The oven includes the shell (301) of the oven burner, the hole (302) for the oven burner, and the support (303) for the oven burner. The assembly of the oven burner requires the completion of two core processes: the docking of the shell and the assembly of the shell and the support. These two processes are generally achieved through riveting to ensure the structural stability during use.
[0003] In the existing technology, the riveting process of oven grill bars generally adopts the traditional riveting mold structure of one mold and one core. This type of mold is designed so that a single mold corresponds to only one set of riveting processes, that is, only two parts can be riveted and fixed at a time. Therefore, when using the above-mentioned riveting mold structure, at least two independent riveting molds need to be configured: one set for riveting and forming the shell, and the other set for riveting and fixing the assembled shell and the bracket.
[0004] The problem is that, with the riveting die structure described above, if both sets of dies work simultaneously, at least two stamping machines and at least two operators are required, increasing the company's energy and labor costs. If the two sets of dies work separately, after one process is completed, the operator needs to change the riveting die for the other process. During the die change process, the stamping equipment needs to be paused for a certain period of time, reducing the utilization rate of the stamping equipment and extending the product production time, resulting in poor product production efficiency and difficulty in meeting the needs of large-scale mass production. In addition, the design, manufacturing, and subsequent maintenance of the two sets of riveting dies all require additional costs, increasing the company's design and maintenance costs.
[0005] Therefore, further improvements are needed. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0031] See Figure 2-10 The riveting mold for the oven grill includes an upper mold assembly 1 and a lower mold assembly 2 arranged vertically. In this embodiment, the upper mold assembly 1 includes an upper template 101, a first upper mold and a second upper mold disposed on the upper template 101, and the lower mold assembly 2 includes a lower template 201, a first lower mold and a second lower mold disposed on the lower template 201. Specifically: The first upper mold includes a first upper riveting recess 102, a first upper riveting protrusion 103, and a first stripper plate 104. The first upper mold has a first upper forming plate 107 and a second upper forming plate 108. The first upper forming plate 107 is hollow and fixed to the bottom surface of the upper template 101. The second upper forming plate 108 is fixed to the bottom surface of the upper template 101 and located within the hollow portion of the first upper forming plate 107. The first upper riveting recess 102 is composed of the first upper forming plate 107 and the second upper forming plate 108. The first upper riveting protrusion 103 is columnar and installed on the upper template 101, extending downwards out of the first stripper plate 104. Preferably, there are two protrusions arranged in a left-right direction. The first unloading plate 104 is movably disposed in the hollow part of the first upper forming plate 107 along the height direction and is located in the gap between the first upper forming plate 107 and the second upper forming plate 108. The first lower mold includes a first lower riveting protrusion 202 corresponding to the first upper riveting recess 102 and a first lower riveting recess 203 corresponding to the first upper riveting protrusion 103. The first lower mold is provided with a first lower forming plate 205, which is fixedly mounted on the top surface of the lower template 201. The first lower riveting protrusion 202 is integrally formed on the top surface of the first lower forming plate 205, and the first lower riveting recess 203 is integrally formed on the top surface of the first lower riveting protrusion 202. The second upper mold includes a second upper riveting protrusion 105 and a second unloading plate 106. The second upper mold is provided with a second upper pressure plate 117, which is hollow and fixed to the bottom surface of the upper template 101. The second upper riveting protrusion 105 is columnar and installed on the upper template 101 and extends downward to the second unloading plate 106. The number of the two protrusions is preferably two and they are arranged at intervals in the left and right directions. The second unloading plate 106 is movably disposed in the hollow part of the second upper pressure plate 117 along the height direction. The second lower mold includes a second lower riveting recess 204 corresponding to the second upper riveting protrusion 105. The second lower mold is provided with a second lower pressure plate 206, which is fixed to the top surface of the lower template 201. The second lower riveting recess 204 is integrally formed on the top surface of the second lower pressure plate 206. The second unloading plate 106 is movably disposed in the hollow part of the second upper pressure plate 117 along the height direction. When the upper mold assembly 1 and the lower mold assembly 2 are engaged, the first upper mold engages with the first lower mold, the inner edge of the first upper forming plate 107 engages with the outer edge of the first lower riveting protrusion 202 to rivet the outer edge of the oven burner shell 301, the outer edge of the second forming plate engages with the inner edge of the first lower riveting protrusion 202 to rivet the inner edge of the oven burner shell 301, and the first upper riveting protrusion 103 engages with the first lower riveting recess 203 to rivet the hole 302 of the oven burner. The structural design of the first upper forming plate 107 and the second upper forming plate 108 provides precise forming space for riveting the outer and inner edges of the oven burner shell 301. After the oven burner shell 301 is riveted, the first unloading plate 104 can smoothly push the oven burner shell 301 downwards and detach it from the forming area of the first upper mold, avoiding scratches or damage to the oven burner shell 301 caused by manual unloading. The deformation improves the unloading efficiency of the oven burner shell 301; the second upper mold cooperates with the second lower mold, and the second upper pressure plate 117 cooperates with the second lower pressure plate 206 to press the oven burner shell 301 tightly; the second upper riveting protrusion 105 cooperates with the second lower riveting recess 204 to rivet the oven burner support 303 onto the oven burner shell 301. The upper and lower corresponding structure of the second upper pressure plate 117 and the second lower pressure plate 206 can pre-press the oven burner shell 301 before riveting, avoiding accidental displacement of the oven burner shell 301 when riveting the oven burner support 303, ensuring the riveting quality of the oven burner; after the oven burner support 303 is riveted, the second unloading plate 106 can smoothly push the oven burner downwards and detach it from the forming area of the second upper mold, avoiding scratches or deformation of the oven burner caused by manual unloading, and improving the unloading efficiency of the oven burner.
[0032] By adopting the riveting mold of the above technical solution, only one set of riveting mold is needed to complete the riveting process of the oven grill. When the riveting mold is working, only one stamping equipment and one operator are needed, which reduces the occupation of stamping equipment and operators, and reduces the energy and labor costs of enterprises.
[0033] By adopting the riveting mold with the above technical solution, there is no need to change the riveting mold before the oven grill is completed, which reduces the time spent on mold changing, improves the utilization rate of stamping equipment and shortens the production time of products, improves the production efficiency of products, and can meet the needs of large-scale mass production to a certain extent.
[0034] By adopting the riveting mold with the above technical solution, only one set of riveting mold is needed to complete the riveting process of the oven grill. A single set of mold can reduce the additional costs of designing, manufacturing and subsequent maintenance of the riveting mold, thereby reducing the design and maintenance costs of enterprises.
[0035] Furthermore, the second lower mold also includes a support block 207, and the second upper mold also includes a clearance hole 109. Specifically, in this embodiment, the support blocks 207 are fixedly mounted on the top surface of the second lower pressure plate 206, and preferably two of them are arranged at intervals along the left and right direction of the second lower pressure plate 206. When the oven burner support 303 is riveted, the oven burner support 303 is placed on the top surface of the two support blocks 207. The two left and right spaced support blocks 207 can provide stable support for the oven burner support 303, ensuring that the oven burner support 303 is horizontal during riveting. The clearance hole 109 is integrally formed on the bottom surface of the second unloading plate 106 and corresponds to the support block 207. When the upper mold assembly 1 and the lower mold assembly 2 are engaged, the two support blocks 207 and the oven burner bracket 303 can be completely embedded in the clearance hole 109. When the riveting mold is working, the clearance hole 109 can accurately avoid the support block 207 and the oven burner bracket 303, avoiding interference and collision between the second unloading plate 106 and the support block 207 and the oven burner bracket 303, ensuring the operational safety and service life of the riveting mold, which can be understood by those skilled in the art.
[0036] Furthermore, the upper mold assembly 1 also includes an upper mold base 110, upper pads 111, and an upper support plate 112. Specifically, in this embodiment, the upper mold base 110 is fixedly mounted on the top surface of the upper template 101, the upper pads 111 are fixedly mounted on the top surface of the upper mold base 110, and the number of them is preferably three and arranged at intervals along the left and right direction. The upper support plate 112 is fixedly mounted on the top surface of the upper pads 111. The upper mold base 110 and the upper support plate 112 form an upper and lower clamping structure, which can enhance the deformation resistance of the upper mold assembly 1 to a certain extent and avoid the positional deviation of the riveting oven burner caused by the deformation of the upper mold assembly 1 under pressure. The structural arrangement of the upper pads 111 not only ensures the stable support of the upper support plate 112, but also reserves sufficient space for the installation of other mechanisms, optimizes the structure of the riveting mold, and makes the structure of the riveting mold more reasonable, which can be understood by those skilled in the art.
[0037] Furthermore, the upper mold assembly 1 also includes a reset mechanism, which is used to reset the first unloading plate 104 and the second unloading plate 106 downwards. Specifically, in this embodiment, the reset mechanism is disposed between the upper support plate 112 and the first unloading plate 104 and the second unloading plate 106. Preferably, there are two reset mechanisms, arranged at intervals along the left-right direction and respectively corresponding to the first unloading plate 104 and the second unloading plate 106. The reset mechanism includes a reset plate 113, a reset push rod 114, and a reset component 115. Preferably, there is one reset plate 113, which is movably disposed between the upper mold base 110 and the upper support plate 112 along the height direction. Preferably, there are several reset push rods 114. The reset components 115 are evenly distributed between the reset plate 113 and the unloading plate, and pass through the upper mold base 110 and the upper template 101. The reset components 115 are preferably nitrogen springs and are fixed on the bottom surface of the upper support plate 112. There are several of them, and they are evenly distributed between the reset plate 113 and the upper support plate 112. Through the above technical solution, the reset mechanism can realize the automatic reset of the first unloading plate 104 and the second unloading plate 106. The elastic force of the reset component 115 is transmitted to the unloading plate through the reset plate 113 and the reset push rod 114, ensuring that the unloading plate can automatically return to the initial position after each riveting without manual adjustment, saving labor costs and ensuring the continuous and stable operation of the riveting mold. This is understandable to those skilled in the art.
[0038] Furthermore, the lower mold assembly 2 also includes a lower mold base 208, lower pads 209, and a lower support plate 210. Specifically, in this embodiment, the lower mold base 208 is fixedly mounted on the bottom surface of the lower mold template 201, the lower pads 209 are fixedly mounted on the bottom surface of the lower mold base 208, and the number of them is preferably four and arranged at intervals along the left and right directions. The lower support plate 210 is fixedly mounted on the bottom surface of the lower pads 209, and the number of them is preferably two and respectively set on the lower pads 209 located on the left and right sides. Through the above technical solutions, the lower pads 209 and the lower support plate 210 cooperate to form a structure with multiple points of distributed support, which reduces the vibration amplitude of the lower mold assembly 2 when subjected to force and enhances the support stability of the lower mold assembly 2, which can be understood by those skilled in the art.
[0039] Furthermore, the riveting mold also includes a guide structure, which guides the upper mold assembly 1 to move relative to the lower mold assembly 2 along the height direction. Specifically, in this embodiment, the guide structure is disposed between the upper mold assembly 1 and the lower mold assembly 2. Preferably, there are four guide structures disposed at the four corners of the riveting mold. The guide structure includes a guide sleeve 211 and a guide post 116. The guide sleeve 211 is disposed on the lower mold base 208 of the lower mold assembly 2, and the guide post 116 is disposed on the upper mold base 110 of the upper mold assembly 1. When the upper mold assembly 1 moves up and down relative to the lower mold assembly 2, the guide post 116 extends into the guide sleeve 211 and slides back and forth along the length direction of the guide sleeve 211. Through the above technical solution, the sliding cooperation between the guide post 116 and the guide sleeve 211 reduces the positional error when the upper mold assembly 1 moves up and down, avoids riveting defects caused by misalignment between the upper mold assembly 1 and the lower mold assembly 2, and extends the service life of the riveting mold. This is understood by those skilled in the art.
[0040] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
