[0001] This utility model belongs to the field of parts processing technology and relates to a processing mold for a U-shaped bracket. Background Technology

[0002] With the booming development of the aerospace industry, the demand for U-shaped support components is becoming increasingly urgent. The delivery requirements for these components are extremely stringent, involving not only delivery quality but also clear and pressing constraints on production cycles. However, the processing methods currently commonly used in the industry are insufficient to meet these requirements.

[0003] For U-shaped bracket parts, current processing methods typically involve bending with a bending machine, requiring two forming processes. This repeated disassembly and reassembly of the part hinders production efficiency. Secondly, the subsequent disassembly and reassembly for bending necessitates re-establishing the assembly reference point. Deviations in this reference point can lead to inconsistent product quality. Furthermore, due to the special materials used in aero-engine bracket parts, ordinary bending machines easily scratch and damage the surface, affecting product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a processing mold for U-shaped brackets to solve the technical problems of low production efficiency and unstable product quality of U-shaped bracket parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a processing mold for a U-shaped bracket, including a pressure block and a lower mold assembly. The lower mold assembly has a concave mold groove, the pressure block is directly opposite the concave mold groove, and the width of the concave mold groove is greater than the width of the pressure block.

[0007] The lower mold assembly is also provided with two bearing rods, which are arranged in parallel and respectively located on the top of the two side walls of the concave mold groove. The circumferential cross-section of the bearing rod is tangent to the side wall plane of the concave mold groove.

[0008] Furthermore, the width of the concave mold groove is equal to the outer width of the U-shaped bracket;

[0009] The width of the pressure block is equal to the inner width of the U-shaped bracket, and the height of the pressure block is greater than the depth of the U-shaped groove of the U-shaped bracket.

[0010] Furthermore, the pressure block and the lower mold assembly are connected by a linear guide component.

[0011] Furthermore, the linear guide component includes a plurality of guide holes formed on the pressure block and a plurality of guide posts disposed in the concave mold groove, wherein the plurality of guide posts are adapted to be embedded in the plurality of guide holes.

[0012] Furthermore, the pressure block is provided with an adapter plate, and the adapter plate has several adapter holes.

[0013] Furthermore, the linear guide component includes a plurality of guide holes formed on the adapter plate and a plurality of guide posts provided on the lower mold assembly, wherein the plurality of guide posts are adapted to be embedded in the plurality of guide holes.

[0014] Furthermore, an ejector is movably mounted on the lower mold assembly, and one end of the ejector can be inserted into the concave mold groove.

[0015] Furthermore, the end face of the ejector can fit against the bottom surface of the U-shaped bracket, and the width of the end face of the ejector along the length of the concave mold groove is greater than the width of the U-shaped bracket along the length of the concave mold groove.

[0016] Furthermore, an elastic reset component is provided between the ejector and the lower mold assembly. The elastic reset component is used to eject the ejector from the concave mold groove when it is squeezed by the U-shaped bracket, and to eject the U-shaped bracket from the concave mold groove when the pressure block exits the concave mold groove.

[0017] Furthermore, the lower mold assembly is provided with a base, the ejector is movably mounted on the base, and the ejector is provided with a connecting part.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model uses a pressure block to apply pressure to parts. The lower mold assembly, as the basic support structure of the entire processing mold, provides a stable platform for part forming. The concave mold groove is the key area for forming the U-shaped bracket part. The width of the concave mold groove is greater than the width of the pressure block, allowing the part material to have a certain amount of room to move within the concave mold groove when the pressure block moves downward to bend and form the part. This facilitates the material to fill the concave mold groove evenly under pressure, thereby ensuring the accurate shape and dimensional stability of the formed U-shaped bracket. During the part processing, when the pressure block applies pressure to the part to bend it, the bearing rod plays a guiding and assisting role in the forming process. The part material comes into contact with the bearing rod during bending. The design of the bearing rod's circumferential cross-section being tangent to the side wall plane of the concave mold groove allows the part material to bend smoothly along the circumferential surface of the bearing rod during bending, reducing the friction between the material and the mold, reducing damage caused by friction, improving the quality of part forming, and also improving processing efficiency and shortening the production cycle. Compared to the traditional method of forming the U-shaped bracket in two stages using a bending machine, this invention can complete the forming process of the U-shaped bracket in one go, greatly shortening the production cycle. At the same time, due to the rational design and coordination of the various components of the mold, the parts are subjected to uniform stress during the forming process, reducing quality instability caused by the special properties of the material, improving the product qualification rate and delivery quality, and better meeting the stringent requirements of the aerospace industry for the delivery of U-shaped bracket parts.

[0020] The width of the concave mold groove of this utility model is equal to the outer width of the U-shaped bracket, ensuring that the outer wall of the U-shaped bracket fits in close contact with the inner wall of the concave mold groove. The width of the pressure block is equal to the inner width of the U-shaped bracket, ensuring that the outer wall of the pressure block fits in close contact with the inner wall of the U-shaped bracket, thus guaranteeing the accurate shape and stable dimensions of the U-shaped bracket.

[0021] The height of the pressure block of this invention is greater than the depth of the U-shaped groove of the U-shaped bracket, which facilitates the pressure application and removal of the pressure block and prevents interference between the component that applies power to the pressure block and the U-shaped bracket.

[0022] The pressure block and the lower mold assembly of this utility model are connected by a linear guide component to ensure that the pressure block applies pressure in a linear direction and to ensure the stability of the pressure application process.

[0023] The pressure block of this utility model is provided with an adapter plate, and the adapter plate has several adapter holes, which facilitates the connection of the pressure block to an external power source through the adapter plate, which is conducive to the automation of the device.

[0024] The present invention provides an elastic reset component between the ejector and the lower mold assembly. The use of the elastic reset component facilitates the quick removal of the U-shaped bracket from the concave mold groove, which is conducive to automation and improves processing efficiency.

[0025] This utility model's top-loading device is equipped with an adapter. The adapter is used to connect the top-loading device to an external power source, which is beneficial for the automation of the top-loading device's operation. Attached Figure Description

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0034] It should be noted that the terms "first," "second," etc., in the specification and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings:

[0036] Example 1:

[0037] See Figure 1 This utility model discloses a processing mold for a U-shaped bracket, including a pressure block 102 and a lower mold assembly 2. The pressure block 102 is a key component in the processing mold that directly applies pressure to the part. The lower mold assembly serves as the basic support structure of the entire processing mold, providing a stable platform for part forming.

[0038] The lower mold assembly 2 has a concave mold groove 201, and the pressure block 102 is directly opposite the concave mold groove 201. The width D1 of the concave mold groove is greater than the width D2 of the pressure block. The concave mold groove 201 is a key area for forming the U-shaped bracket part. The shape and size of the concave mold groove 201 determine the final shape of the U-shaped bracket. The fact that the width D1 of the concave mold groove is greater than the width D2 of the pressure block allows the part material to have a certain amount of room to move within the concave mold groove 201 when the pressure block 102 moves downward to bend and form the part. This facilitates the material to fill the concave mold groove 201 evenly under pressure, thereby ensuring that the U-shaped bracket 4 has an accurate shape and stable dimensions after forming.

[0039] The lower mold assembly 2 is also equipped with two bearing rods 203. The two bearing rods 203 are arranged in parallel and respectively located on the top of the two side walls of the concave mold groove 201. The circumferential cross-section of the bearing rod 203 is tangent to the side wall plane of the concave mold groove 201. During part processing, when the pressure block applies pressure to the part to bend it, the bearing rods play a guiding and assisting role in forming. The part material comes into contact with the bearing rods during bending. The design of the bearing rod's circumferential cross-section being tangent to the side wall plane of the concave mold groove allows the part material to bend smoothly along the circumferential surface of the bearing rod during bending, reducing the friction between the material and the mold, reducing damage to the material caused by friction, helping to improve the quality of part forming, and also improving processing efficiency and shortening the production cycle.

[0040] Compared to the traditional method of forming the U-shaped bracket 4 in two stages using a bending machine, this invention can complete the forming process of the U-shaped bracket 4 in one go, greatly shortening the production cycle. At the same time, due to the reasonable design and coordination of the various components of the mold, the parts are subjected to uniform stress during the forming process, reducing quality instability caused by the special properties of the material, improving the product qualification rate and delivery quality, and better meeting the stringent requirements of the aerospace industry for the delivery of U-shaped bracket 4 type parts.

[0041] Based on the above structure, the specific method of using this utility model is as follows:

[0042] See Figure 4 Place the bracket to be processed above the concave mold groove 201 of the lower mold group, ensuring that the bracket to be processed is centered;

[0043] The pressure block 102 is slowly moved downwards to press down the support to be processed.

[0044] As the pressure block 102 continues to press down, the support to be processed begins to gradually bend along the shape of the concave mold groove 201. At this time, the bearing rod 203 plays a guiding and assisting role in forming, and the support to be processed will bend smoothly along the circumferential surface of the bearing rod 203.

[0045] See Figure 5 When the pressure block 102 is pressed down to the predetermined position, so that the plate is completely formed into the U-shaped bracket 4, the pressure of the pressure block 102 is maintained for a period of time to ensure that the part is fully shaped and to reduce the rebound phenomenon.

[0046] In this embodiment of the present invention, the width D1 of the concave mold groove is equal to the outer width D3 of the U-shaped bracket, ensuring that the outer wall of the U-shaped bracket 4 fits against the inner wall of the concave mold groove 201, thus ensuring the accurate shape and stable dimensions of the U-shaped bracket 4.

[0047] The width D2 of the pressure block is equal to the inner width D4 of the U-shaped bracket, ensuring that the outer wall of the pressure block 102 fits against the inner wall of the U-shaped bracket 4, thus ensuring the accurate shape and stable dimensions of the U-shaped bracket 4.

[0048] The height of the pressure block 102 is greater than the depth H of the U-shaped groove of the U-shaped bracket, which facilitates the pressure application and removal of the pressure block 102 and prevents the component that applies power to the pressure block 102 from interfering with the U-shaped bracket 4.

[0049] In this embodiment of the present invention, the pressure block 102 is connected to the lower mold group 2 by a linear guide component, which is used to ensure that the pressure block 102 applies pressure in a linear direction and to ensure the stability of the pressure application process of the pressure block 102.

[0050] See Figure 2In this embodiment of the present invention, the linear guide component includes a plurality of guide holes 104 formed on the pressure block 102 and a plurality of guide posts 202 disposed in the concave mold groove 201, wherein the plurality of guide posts 202 are adapted to be embedded in the plurality of guide holes 104.

[0051] See Figure 1 and Figure 2 In this embodiment of the utility model, the pressure block 102 is provided with an adapter plate 101, and the adapter plate 101 is provided with a plurality of adapter holes 103, which facilitates the connection of the pressure block 102 to an external power source through the adapter plate 101, which is beneficial to the automation of the device.

[0052] See Figures 1 to 3 In this embodiment of the present invention, an ejector 3 is movably mounted on the lower mold assembly 2, and one end of the ejector 3 can be inserted into the concave mold groove 201. After the U-shaped bracket 4 is formed, the pressure block 102 is pushed out, and the ejector 3 extends into the concave mold groove 201 and pushes out the U-shaped bracket 4.

[0053] See Figure 5 and Figure 6 In this embodiment of the present invention, the end face of the ejector 3 can fit against the bottom surface of the U-shaped bracket 4, and the width of the end face of the ejector 3 along the length direction of the concave mold groove 201 is greater than the width of the U-shaped bracket 4 along the length direction of the concave mold groove 201. See [reference needed]. Figure 4 .

[0054] In this embodiment of the invention, an elastic reset component is provided between the ejector 3 and the lower mold assembly 2. The elastic reset component is used to eject the ejector 3 from the concave mold groove 201 when it is pressed by the U-shaped bracket 4, and to eject the U-shaped bracket 4 out of the concave mold groove 201 when the pressure block 102 exits the concave mold groove 201. The use of the elastic reset component facilitates the rapid removal of the U-shaped bracket 4 from the concave mold groove 201, promotes automation, and improves processing efficiency.

[0055] Example 2:

[0056] See Figure 1 This utility model discloses a processing mold for a U-shaped bracket. Unlike Embodiment 1, in this embodiment:

[0057] The linear guide component includes a plurality of guide holes 104 formed on the adapter plate 101 and a plurality of guide posts 202 provided on the lower mold assembly 2, wherein the plurality of guide posts 202 are adapted to be embedded in the plurality of guide holes 104.

[0058] The lower mold assembly 2 is provided with a base 204, and the ejector 3 is movably mounted on the base 204. The ejector 3 is provided with a connecting part. The connecting part is used to connect the ejector 3 to an external power source, which is conducive to the automation of the ejector 3's operation.

[0059] The method of using this utility model is as follows:

[0060] See Figure 4 Place the support to be processed on the top piece 3, so that the top end face of the top piece 3 contacts the bottom of the support to be processed, and adjust the placement position.

[0061] See Figure 5 Press down the upper mold assembly 1, and the concave mold groove 201 cooperates with the pressure block 102 of the upper mold assembly 1 to bend the bracket to be processed, so that the bracket to be processed is formed by two bends in one step.

[0062] See Figure 6 After the U-shaped bracket 4 is formed, it is ejected by the ejector 3.

[0063] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of this utility model.
