Description

Technical Field

[0001] This utility model relates to the field of press technology, specifically to a flange press mold with an anti-deformation device. Background Technology

[0002] Presses are characterized by their wide range of applications and high production efficiency. They can be widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. They process metal parts by applying strong pressure to metal blanks to cause plastic deformation and fracture.

[0003] For example, the national authorized patent announcement number CN221087145U discloses a flange processing press, including a main body component. The main body component includes an operating table, with a vertical plate fixedly connected to the upper surface of the operating table. A vertical groove is vertically opened inside the vertical plate. A pushing component is provided on the upper part of the operating table, including a slider. The slider is installed inside the groove, and a first rack is fixedly connected to the rear side wall of the slider. A rotating shaft is horizontally rotatably connected inside the vertical plate. A first gear is fixedly connected to the rear end of the rotating shaft, and a first wheel is fixedly connected to the front end of the rotating shaft. A support is fixedly connected to the upper surface of the operating table. This utility model can push the processed flange directly under the forging head by the pushing plate when the forging head is raised after forging, avoiding the need for the operator to manually remove the flange, which may cause accidental pinching and injury, thus improving the safety performance of use.

[0004] However, the aforementioned flange processing press only supports the flange blank through a "support" and does not have a precise positioning device for the flange's annular structure. This makes it easy for the blank to slide or shift horizontally due to pressure impact during the forging process, resulting in the flange's center shift and edge asymmetry. This directly affects the sealing performance of subsequent assembly and also makes it difficult to ensure the perpendicularity between the forging head and the blank, which can easily cause local thickness deviations or warping of the flange. Utility Model Content

[0005] The purpose of this utility model is to provide a flange press mold with an anti-deformation device to solve the problems mentioned in the background art, such as horizontal sliding, center offset, edge asymmetry, and local thickness deviation and warping caused by insufficient forging verticality of the flange blank during the forging process due to the lack of precise positioning and rigid constraint, which in turn affects the subsequent assembly sealing performance and product quality stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flange press mold with an anti-deformation device includes: a mounting plate, a press fixedly mounted on the upper surface of the mounting plate, a connecting plate fixedly mounted on the lower surface of the output shaft of the press, a limiting ring fixedly mounted on the lower surface of the connecting plate, an upper mold in the limiting ring being a conical protrusion and perpendicular to the mold groove ring, the mold groove ring being embedded in the upper surface of the bearing column, and a stripping mechanism being slidably mounted on the inner central shaft portion of the mold groove ring.

[0008] Preferably, the upper surface of the mold groove ring is provided with four sets of material picking grooves, which can be inserted into the filling plate to form a complete ring.

[0009] Preferably, when the limiting ring drives the upper die to move down with the output shaft of the press and insert into the die groove ring, it will also be inserted into the limiting groove to support the outer periphery of the die groove ring. The limiting groove is embedded in the upper surface of the bearing column and located at the outer periphery of the die groove ring.

[0010] Preferably, the stripping mechanism includes a connecting column, which is slidably installed in a guide groove. The guide groove is opened in the bearing column and located at the center of the mold groove ring. Guide rail blocks are fixedly installed at both ends of the outer surface of the connecting column. The guide rail blocks are slidably installed in the guide rail groove, which is opened at both ends of the guide groove, so that the connecting column can slide into the guide groove through the guide rail blocks and be flush with the surface of the mold groove ring.

[0011] Preferably, the upper surface of the connecting column is an embedded conical shape and can fit into the upper mold of the limiting ring.

[0012] Preferably, a rectangular spring is fixedly connected to the lower surface of the connecting column, and the other end of the rectangular spring is fixedly connected to the guide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By using the rigid support of the limiting ring and the limiting groove, the filling plate to close the material feeding groove, and the conical surface of the conical upper mold and the connecting column to cooperate, it is possible to avoid the deformation of the mold groove ring under force and to use the "reverse deformation amount" to offset the rebound, ensuring the accuracy of the flange conical surface angle. At the same time, the unloading mechanism composed of the connecting column guided by the guide block and the rectangular spring realizes the stable support of the blank and the automatic ejection of the finished product, which greatly improves the processing accuracy and operating efficiency.

[0019] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-2 As shown, a flange press mold with an anti-deformation device includes: a mounting plate 101, a press 1 fixedly mounted on the upper surface of the mounting plate 101, a connecting plate 102 fixedly mounted on the lower surface of the output shaft of the press 1, a limiting ring 107 fixedly mounted on the lower surface of the connecting plate 102, an upper mold in the limiting ring 107 being a conical protrusion and perpendicular to the mold groove ring 105, the mold groove ring 105 being embedded in the upper surface of the bearing column 103, and a stripping mechanism 2 being slidably mounted on the inner central shaft of the mold groove ring 105.

[0021] The upper surface of the mold groove ring 105 is provided with four sets of material picking grooves 106. The material picking grooves 106 can be inserted into the filling plate 109 to form a complete ring. When the limiting ring 107 drives the upper mold to move down with the output shaft of the press 1 and inserts into the mold groove ring 105, it will also be inserted into the limiting groove 104 to support the periphery of the mold groove ring 105. The limiting groove 104 is embedded in the upper surface of the bearing column 103 and is located at the periphery of the mold groove ring 105.

[0022] Through the design of press 1, connecting plate 102, bearing column 103, limiting groove 104, die groove ring 105, material receiving groove 106, limiting ring 107, filling plate 109, and unloading mechanism 2, when pressing the flange, the flange blank is placed in the die groove ring 105, and then the press 1 is started to drive the connecting plate 102 and limiting ring 107 to move down synchronously through the output shaft. During the downward movement, the limiting ring 107 and the filling plate 109 will successively insert into the limiting groove on the bearing column 103. The slot 104 and the take-up slot 106 respectively form rigid support for the outer periphery of the die groove ring 105 and fill the take-up slot 106 to form a complete ring. The limiting ring 107 supports the die groove ring 105 to prevent deformation of the die groove ring 105 due to force during forging. Subsequently, as the press 1 drives the limiting ring 107 to continue to move downward, the conical upper die in the limiting ring 107 can be gradually pressed into the flange blank in the die groove ring 105, and the flange blank can then push the protruding stripping mechanism 2. The material is pressed into the guide groove 110 until it is flush with the surface of the die ring 105. As the press 1 continues to apply pressure, the contact area between the upper die conical structure and the blank gradually increases, allowing the pressure to be evenly transmitted to all parts of the blank. Under the pressure of the conical upper die, the blank gradually conforms to the cavity shape formed by the die ring 105 and the stripping mechanism 2, undergoing plastic deformation. This conical application effectively counteracts the springback effect after the flange is processed by the "reverse deformation amount" generated by the flange. After the forging is completed, the pressure is released, and the material springs back due to elastic recovery. At this time, the preset "reverse deformation amount" is exactly offset by the springback, so that the conical angle of the flange accurately meets the design standard. After the forging is completed, the output shaft of the press 1 drives the upper die and the limiting ring 107 to reset upward. The stripping mechanism 2 can then reset upward under its own elasticity, thereby automatically pushing the formed flange out of the die ring 105 to a certain height. Then, the formed flange can be easily removed from the die ring 105 through the material removal groove 106.

[0023] like Figure 3 As shown, the stripping mechanism 2 includes a connecting column 201, which is slidably installed in the guide groove 110. The guide groove 110 is opened in the bearing column 103 and is located at the center of the mold groove ring 105. Guide rail blocks 203 are fixedly installed at both ends of the outer surface of the connecting column 201. The guide rail blocks 203 are slidably installed in the guide rail groove 108, which is opened at both ends of the guide groove 110. This allows the connecting column 201 to slide into the guide groove 110 through the guide rail blocks 203 and be flush with the surface of the mold groove ring 105.

[0024] The upper surface of the connecting post 201 is an embedded conical shape that fits into the upper mold of the limiting ring 107. A rectangular spring 202 is fixedly connected to the lower surface of the connecting post 201, and the other end of the rectangular spring 202 is fixedly connected to the guide groove 110.

[0025] Through the design of the connecting column 201, rectangular spring 202, and guide block 203, when the flange blank is placed in the die groove ring 105, the connecting column 201 is pushed upward by the elastic force of the rectangular spring 202, and the embedded conical surface of the upper surface precisely corresponds to the conical upper die in the limiting ring 107. After the forging starts, as the limiting ring 107 drives the conical upper die to move downward and press against the blank, the blank is forced downward to push the connecting column 201. At this time, the connecting column 201 slides down steadily along the guide groove 108 through the guide blocks 203 at both ends and compacts the rectangular spring 202 to shrink and store energy. During this process, the sliding cooperation between the guide block 203 and the guide groove 108 strictly limits the movement trajectory of the connecting column 201 to prevent it from deviating or tilting, ensuring that the upper surface of the connecting column 201 always maintains surface contact with the conical upper die, ensuring that the pressure is evenly transmitted from the center to the edge of the blank. At the same time, the connecting column 201 gradually... The blank retracts into the guide groove 110 and finally becomes flush with the surface of the die groove ring 105, forming a complete cavity together with the die groove ring 105. This allows the blank to fully conform to the cavity and complete plastic deformation. After forging, the press 1 can drive the upper die and the limiting ring 107 to return to their original position. The pressure is released, the rectangular spring 202 releases its stored energy, and pushes the connecting column 201 to slide upward along the guide rail groove 108 to return to its original position. Its top pushes the formed flange, pushing the flange out of the die groove ring 105 to a certain height, making it easy to remove it through the material removal groove 106 later. Throughout the process, the conical design of the connecting column 201 matches the conical surface of the upper die, which not only helps to achieve precise control of the "anti-deformation amount" to offset the rebound, but also ensures the stability of the movement through the guiding action of the guide rail block 203. The rectangular spring 202 provides stable elastic support and return power. The three work together to ensure the smoothness of the forging process and the convenience of demolding.

[0026] Based on the above technical solution, the working steps of this solution are summarized as follows: When pressing the flange, the flange blank is placed in the die groove ring 105, and then the press 1 is started to drive the connecting plate 102 and the limiting ring 107 to move down synchronously through the output shaft. During the downward movement, the limiting ring 107 and the filling plate 109 will be inserted into the limiting groove 104 and the material taking groove 106 on the bearing column 103 respectively, forming rigid support for the outer periphery of the die groove ring 105 and filling the material taking groove 106 to form a complete ring. The support of the die groove ring 105 by the limiting ring 107 can prevent the die groove ring 105 from deforming due to force during forging. Subsequently, as the press 1 drives the limiting ring 107 to continue to move down, the conical upper die in the limiting ring 107 can be gradually pressed into the flange blank in the die groove ring 105, and the blank can then be pushed downward by force to push the connecting column 201. At this time, the connecting column 201 is guided by the guide blocks 203 at both ends. The rectangular spring 202 contracts and stores energy as it slides steadily down the guide groove 108 and compresses the rectangular spring 202. At the same time, the connecting column 201 gradually retracts into the guide groove 110, eventually becoming flush with the surface of the mold groove ring 105, forming a complete cavity together with the mold groove ring 105. This allows the blank to fully conform to the cavity and complete plastic deformation. After forging, the press 1 can drive the upper mold and the limiting ring 107 to reset upwards. The pressure is released, the rectangular spring 202 releases its stored energy, and pushes the connecting column 201 to slide upwards and reset along the guide groove 108. Its top pushes the formed flange, pushing the flange out of the mold groove ring 105 to a certain height, making it easy to remove through the material removal groove 106 later. Throughout the process, the conical design of the connecting column 201 matches the conical surface of the upper mold, which helps to achieve precise control of the "anti-deformation amount" to offset the springback. After the pressure is released after forging, the preset "anti-deformation amount" is exactly offset by the springback, ultimately making the conical angle of the flange accurately meet the design standard.

[0027] In summary: By matching the conical surface design of the connecting column 201 with the conical surface of the upper die, it not only helps to achieve precise control of the "anti-deformation amount" to offset the rebound, but also, through the elastic support and reset power provided by the rectangular spring 202, the three work together to ensure the smoothness of the forging process and the convenience of demolding.
