Description

Technical Field

[0001] This utility model belongs to the technical field of manufacturing cone-top tooling, and specifically relates to a tooling for manufacturing cone-tops. Background Technology

[0002] Conical tops (conical caps) are a common type of end cap used in pressure vessels such as containers, tanks, and towers. They are cone-shaped structures formed by plastic deformation of a flat, circular steel plate. It is extremely difficult to directly handcraft a cone top with precise dimensions and a regular shape, especially for steel plates of a certain thickness.

[0003] Currently, when stamping cone tops, there is a lack of structure to effectively position the metal sheet, which cannot keep it centered with the mold. This results in the cone top being out of center, affecting the quality of the finished cone top. In addition, the stamped cone top is disassembled directly within the stamping working distance of the stamping equipment, which poses certain safety risks. Accidental start-up of the stamping equipment can cause injury to the workers handling the material. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tooling for manufacturing cone tops.

[0005] To achieve the above objectives, this utility model provides a tooling for manufacturing cone tops, including a processing table. A plurality of support columns are fixedly connected to the top surface of the processing table, a top plate is fixedly connected to the top of the support columns, a pressing structure is fixedly connected to the bottom surface of the top plate, a pick-up opening is provided on the side of the processing table, a through vertical opening is provided on the top surface of the pick-up opening, a shrinking structure is fixedly connected inside the pick-up opening, and a positioning component is fixedly connected to the surface of the vertical opening. The pressing structure includes a first hydraulic push rod fixedly connected to the bottom surface of the top plate and a concave mold fixedly connected to the bottom end of the first hydraulic push rod; The shrinking structure includes a second hydraulic push rod fixedly connected inside the retrieval port and a support plate fixedly connected to the top surface of the second hydraulic push rod. The support plate is slidably connected inside the vertical opening and its top surface is fixedly connected to a convex mold that fits with the concave mold. The positioning component includes a positioning sleeve fixedly connected to the surface of a vertical opening. The side of the positioning sleeve has several threaded holes, and a screw is threadedly connected to the inside of the threaded holes. One end of the screw is fitted with a bearing, and a positioning plate is fixedly connected to the side of the bearing.

[0006] In the above technical solution, the punch can move up and down inside the vertical opening by being driven by the second hydraulic push rod, and has a lower limit position so that the top surface of the punch is lower than the top surface of the processing table.

[0007] In the above technical solution, the positioning plates are further configured as multiple plates and distributed in a rectangular array around the punch, and each positioning plate can be moved horizontally independently by rotating the corresponding screw.

[0008] In the above technical solution, the size of the tray is further adapted to the size of the vertical opening to achieve a sliding fit.

[0009] In the above technical solution, the concave mold and the convex mold together constitute a cavity for forming the cone top.

[0010] In the above technical solution, the height of the picking opening is greater than the height of the cone top after molding.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model utilizes a positioning component and a horizontally movable positioning plate to center and clamp a metal sheet. Specifically, by rotating a screw threaded to the side of the positioning sleeve, the positioning plate, connected to a bearing at its end, moves synchronously, thereby coordinating adjustments from multiple directions to ensure that the sheet is precisely centered above the punch before stamping. When the die is pressed down for stamping, the sheet undergoes plastic deformation during the forming process, and its edges naturally detach from the initial constraint of the positioning plate. This ensures accurate positioning before forming and avoids interference from the positioning structure to the free deformation of the sheet, effectively solving the problem of cone apex eccentricity caused by initial misalignment and significantly improving the quality of the finished product. 2. This utility model, through its designed shrinkage structure, allows the punch and the formed workpiece to descend as a whole into the pick-up port of the processing table after stamping. This structure completely removes the workpiece from the upper stamping execution area, allowing operators to safely retrieve the part from the side without operating directly below the equipment. This fundamentally eliminates the safety risks that may be caused by accidental movement of the stamping equipment and greatly improves the safety of the operation process.

[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1-4 The tooling for making a cone top shown includes a processing table 1, a number of support columns 2 fixedly connected to the top surface of the processing table 1, a top plate 3 fixedly connected to the top of the support columns 2, a pressing structure 4 fixedly connected to the bottom surface of the top plate 3, a pick-up opening on the side of the processing table 1, a through vertical opening on the top surface of the pick-up opening, a shrinking structure 5 fixedly connected inside the pick-up opening, and a positioning component 6 fixedly connected to the surface of the vertical opening. The pressing structure 4 includes a first hydraulic push rod 41 fixedly connected to the bottom surface of the top plate 3 and a concave mold 42 fixedly connected to the bottom end of the first hydraulic push rod 41; The shrinking structure 5 includes a second hydraulic push rod 51 fixedly connected inside the take-up port and a support plate 52 fixedly connected to the top surface of the second hydraulic push rod 51. The support plate 52 is slidably connected inside the vertical opening and its top surface is fixedly connected to a punch 53 that fits with the concave die 42. During operation, when safely removing parts, after the concave die 42 returns to its original position, the second hydraulic push rod 51 inside the pick-up port retracts, causing the support plate 52 to move downwards along the vertical opening. This causes the convex die 53 and the forming cone top, which are fixed on the support plate 52, to descend synchronously into the internal space of the pick-up port. During this process, the workpiece is completely removed from the stroke range of the concave die 42, and the operator can safely remove the part from the pick-up port on the side of the processing table 1, effectively avoiding the risks caused by unexpected actions of the stamping equipment.

[0016] Furthermore, the positioning component 6 includes a positioning sleeve 61 fixedly connected to the surface of the vertical opening. The side of the positioning sleeve 61 is provided with several threaded holes. The threaded holes are threadedly connected to a screw 62. One end of the screw 62 is sleeved with a bearing 63. The side of the bearing 63 is fixedly connected to a positioning plate 64. During operation, when positioning the sheet metal, the operator first places the sheet metal on the top surface of the punch 53, and then rotates the screws 62 in each direction of the positioning sleeve 61 in sequence. The screws 62 push the positioning plate 64 to move horizontally and centripetally through the end bearing 63, clamping the sheet metal from multiple directions simultaneously so that it is precisely centered on the center of the punch 53. When the first hydraulic push rod 41 drives the die 42 to press down, the sheet metal undergoes plastic deformation and extends into the die cavity. Its outer edge then breaks away from the initial constraint of the positioning plate 64, thereby completing the non-interference stamping forming while ensuring the initial positioning accuracy.

[0017] Furthermore, the concave mold 42 and the convex mold 53 together constitute a cavity for forming the cone top. During operation, the concave mold 42 moves downward under the drive of the hydraulic push rod, forming a closed cavity together with the convex mold 53 fixed on the support plate 52. The metal sheet to be processed is squeezed and plastically deformed within this cavity, precisely filling the cavity space to form a cone top. This embodiment ensures the uniformity of material flow and dimensional accuracy during the cone top forming process through the precise fit between the concave mold 42 and the convex mold 53, effectively avoiding defects such as bulges and wrinkles, and significantly improving the shape accuracy and surface quality of the cone top product.

[0018] Furthermore, the height of the retrieval opening is greater than the height of the cone apex after molding; During operation, when performing the part-retrieving operation, the shrinking structure 5 drives the punch 53 and the forming cone to descend into the retrieval port. Since the height of the retrieval port is designed to be greater than the vertical height of the forming cone, the cone-shaped workpiece can be completely accommodated within this space. This implementation provides the necessary operating space for side-mounted part retrieval, ensuring that the formed workpiece can smoothly leave the working area, avoiding collision damage between the workpiece and the edge of the processing table 1 during the retrieval process, while reducing the difficulty of operation and improving part-retrieving efficiency and work safety.

[0019] Working principle: At the start of operation, the operator places a circular metal sheet horizontally on the top surface of the punch 53, and then screws 62 around the positioning sleeve 61 in sequence. The screws 62 smoothly push the positioning plate 64 towards the center through the end bearing 63, simultaneously contacting the edge of the sheet from multiple directions and applying uniform pressure, achieving precise centering and reliable clamping of the sheet on the upper surface of the punch 53. When the stamping program starts, the first hydraulic push rod 41 fixed to the top plate 3 drives the concave die 42 to move downward. After the concave die 42 contacts the sheet, it continues to apply pressure, causing the sheet to gradually undergo plastic deformation between the concave inner surface of the concave die 42 and the convex outer surface of the punch 53. During the deformation process, the edge of the sheet metal naturally detaches from the constraint of the positioning plate 64 and eventually fits completely into the mold cavity to form a standard cone top. After the forming is completed, the first hydraulic push rod 41 drives the concave mold 42 to rise back to the initial position. Then, the second hydraulic push rod 51 in the take-up port begins to retract, driving the support plate 52 to descend smoothly along the inner side of the vertical opening. This causes the convex mold 53 fixed on the support plate 52 and the formed cone top to move down synchronously into the processing table 1. When the top surface of the convex mold 53 drops below the working plane of the processing table 1, the entire cone top workpiece is completely inside the protective space of the take-up port. The operator can then safely and conveniently remove the finished workpiece from the take-up port on the side of the processing table 1.

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 the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
