Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a conical head processing device that is easy to position. Background Technology

[0002] A conical head processing device is typically an industrial piece of equipment based on the principle of pressure forming. Its core function is to cold or hot press a circular metal sheet of a specific size into a mold under immense pressure, producing conical head products widely used in petrochemical, food and pharmaceutical, and pressure vessel industries. The basic structure of this device includes a power press system and a crucial upper and lower mold. The upper mold is mounted on the press slide, and its working surface is a specific conical convex surface. The lower mold is fixed to the equipment's worktable, and its working surface forms a conical concave surface that matches the upper mold. During operation, the operator first places the pre-cut circular steel sheet on the concave surface of the lower mold. Then, the press drives the upper mold downwards, closing it with the lower mold. The immense pressure forces the metal sheet to undergo plastic deformation within the mold cavity, ultimately conforming to the mold shape to form a conical head.

[0003] In existing technologies, the traditional method for positioning conical heads during processing relies heavily on the operator's personal experience and visual judgment. The position of the steel plate on the lower die is roughly adjusted by manually pushing or using simple levers, pry bars, or other tools. This method is not only inefficient and labor-intensive, but also makes it difficult to guarantee the repeatability of each placement. It is also very easy for human error to cause deviations between the center of the steel plate and the center of the die. These tiny misalignments will be amplified after subsequent high-pressure stamping, directly leading to defects such as uneven wall thickness and out-of-tolerance geometric shape, which seriously affects product quality and needs improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a conical head processing device that facilitates positioning. Through a purely mechanical linkage mechanism consisting of a positioning mechanism and a support mechanism, simple manual input is precisely converted into synchronous linear pushing action at multiple positioning points, achieving rapid, accurate, and reliable centering and positioning of the conical head steel plate, which greatly improves the accuracy and efficiency of subsequent stamping.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a conical head processing device for easy positioning, comprising a top support, an upper mold mounted on the top support, a lower mold provided below the upper mold, and the lower mold mounted on a bottom support; The bottom bracket includes a positioning mechanism mounted on a support mechanism. The positioning mechanism includes a connecting ring bolted to the support mechanism. The connecting ring is connected to a connecting shaft that overlaps with the axis of the connecting ring via a connecting rod. A rotating ring is rotatably connected to the connecting shaft. A lever is fixedly mounted at the bottom of the rotating ring. A transmission rod is rotatably connected to the outer edge of the rotating ring. A transmission rod is rotatably connected to the end of the transmission rod away from the rotating ring. The transmission rod is slidably inserted into a limiting rod. One end of the limiting rod is fixedly mounted on the connecting ring. The end of the transmission rod away from the transmission rod is slidably connected to a sliding groove. The sliding groove is formed on one end of a U-shaped rod. A stop rod is rotatably connected to the end of the U-shaped rod away from the sliding groove. The middle positions of the U-shaped rod and the stop rod are connected by a reset spring.

[0006] In a preferred embodiment, the support mechanism includes a leg structure, a threaded rod with a handle is threadedly connected to the top of the leg structure, a push plate is rotatably connected to one end of the threaded rod near the lower mold, a ruler rod is mounted on the push plate, the ruler rod is slidably inserted into the top of the leg structure, and an inner connecting frame is mounted on the leg structure and fixedly connected to the connecting ring.

[0007] In a preferred embodiment, the top support includes a mounting bracket, which is fixedly connected to the upper mold via a press assembly. The upper mold and the mounting bracket are also connected by a telescopic limiting connecting rod.

[0008] In a preferred embodiment, a pulley is provided on the end of the abutment rod away from the U-shaped rod, and when the U-shaped rod extends, the pulley is attached to the upper surface of the lower mold.

[0009] In a preferred embodiment, the end of the limiting rod away from the connecting ring is rotatably connected to the middle position of the U-shaped rod via the second connecting rod.

[0010] In a preferred embodiment, the angle between the U-shaped rod and the abutment is an obtuse angle.

[0011] In a preferred embodiment, the lower mold is mounted on a support structure on one side of the push plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes a purely mechanical linkage mechanism comprised of a positioning mechanism and a support mechanism to precisely transform simple manual input into synchronous linear pushing action at multiple positioning points. This achieves rapid, accurate, and reliable centering and positioning of the conical end cap steel plate, greatly improving the accuracy and efficiency of subsequent stamping. Furthermore, the self-locking characteristic of the threaded transmission ensures the firm fixation of the lower die position after adjustment, and the use of a ruler rod enables the quantification and visualization of the adjustment process, significantly improving the centering accuracy and adjustment efficiency of the lower die relative to the upper die.

[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. Example

[0020] like Figures 1 to 3 As shown, this utility model provides a technical solution: a conical head processing device that is easy to position, including a top support 1, an upper mold 2 installed on the top support 1, a lower mold 4 provided below the upper mold 2, and the lower mold 4 installed on a bottom support 3; The top support 1 includes a mounting bracket 11, which is fixedly connected to the upper mold 2 via the press assembly 12. The upper mold 2 and the mounting bracket 11 are also connected by a telescopic limiting connecting rod 13. The bottom bracket 3 includes a positioning mechanism 32 mounted on the support mechanism 31.

[0021] In this embodiment, the mounting bracket 11 of the top bracket 1 provides a stable support frame for the entire system. The press assembly 12 is responsible for driving the upper die 2 to perform vertical stamping action to shape the sheet metal. The telescopic limiting connecting rod 13 connecting the upper die 2 and the mounting bracket 11 ensures the accuracy and stability of the movement trajectory of the upper die 2 under the drive of the press assembly 12, effectively preventing skewing or shaking. At the same time, the lower die 4 placed on the bottom bracket 3 works together with the upper die 2 to form a forming mold. Its position is fixed by the support mechanism 31 of the bottom bracket 3, and provides a basis for the operation of the subsequent positioning mechanism 32. Example

[0022] like Figure 3 , Figure 4 and Figure 5As shown, the support mechanism 31 includes a leg structure 311. A threaded rod 312 with a handle is threadedly connected to the top of the leg structure 311. A push plate 313 is rotatably connected to one end of the threaded rod 312 near the lower mold 4. The lower mold 4 is mounted on the leg structure 311 on one side of the push plate 313. A scale rod 314 is mounted on the push plate 313 and slidably inserted into the top of the leg structure 311. An inner connecting bracket 315 is mounted on the leg structure 311 and fixedly connected to the connecting ring 321. In this design, the operator converts the rotational motion into linear motion by rotating the threaded rod 312 with the handle, utilizing the threaded connection between the threaded rod 312 and the top of the leg structure 311, thereby pushing the rotating connection therewith. The push plate 313 moves horizontally. Since the lower mold 4 is mounted on the support structure 311 on one side of the push plate 313, the linear movement of the push plate 313 can directly push and adjust the horizontal position of the lower mold 4 on the support structure 311. At the same time, the scale rod 314 fixedly installed on the push plate 313 will move synchronously with the push plate 313. Since it is slidably inserted into the top of the support structure 311, its displacement relative to the support structure 311 can be displayed intuitively through the scale, providing a precise numerical basis for the position adjustment of the lower mold 4. The inner connecting frame 315 fixedly installed on the support structure 311 ensures a stable connection with the connecting ring 321, thereby providing a high-rigidity installation base for the entire positioning mechanism 32. Furthermore, the positioning mechanism 32 includes a connecting ring 321 bolted to the support mechanism 31. The connecting ring 321 is connected to a connecting shaft 323 that overlaps with the axis of the connecting ring 321 via a connecting rod 322. A rotating ring 324 is rotatably connected to the connecting shaft 323. A lever 325 is fixedly installed at the bottom of the rotating ring 324. A transmission rod 326 is rotatably connected to the outer edge of the rotating ring 324. A transmission rod 327 is rotatably connected to the end of the transmission rod 326 away from the rotating ring 324. The transmission rod 327 is slidably inserted into a limiting rod 328. One end of the limiting rod 328 is fixedly installed on the connecting ring. On 321, the end of transmission rod 2 327 away from transmission rod 1 326 is slidably connected in the groove 3210. The groove 3210 is formed on one end of the U-shaped rod 329. The end of the U-shaped rod 329 away from the groove 3210 is rotatably connected to a stop rod 3212. A pulley is provided on the end of the stop rod 3212 away from the U-shaped rod 329. When the U-shaped rod 329 extends, the pulley is in contact with the upper surface of the lower mold 4. The middle position of the U-shaped rod 329 and the stop rod 3212 is connected by a reset spring 3213. The included angle between the U-shaped rod 329 and the stop rod 3212 is an obtuse angle. In this design... The operator manually moves lever 325, causing the rotating ring 324, which is fixedly connected to lever 325, to rotate around connecting shaft 323. The rotational motion of the rotating ring 324 is converted into the horizontal displacement of transmission rod 326 through the rotational connection point on its outer edge. Transmission rod 326 then pushes transmission rod 327, which is rotatably connected to it. Since transmission rod 327 is slidably inserted into the limiting rod 328 fixed to connecting ring 321, its movement is constrained to extend along the straight line of limiting rod 328. When transmission rod 327 extends, its end slides in the groove 3210 of U-shaped rod 329. The motion is converted into a pushing force on one end of the U-shaped rod 329, causing the U-shaped rod 329 to perform lever motion with its rotational connection point with the connecting rod 3211 as the fulcrum, thereby causing its other end to extend outward and push the abutment rod 3212 and its pulley at the end to move towards the center of the lower mold 4. At this time, the obtuse angle structure formed between the U-shaped rod 329 and the abutment rod 3212 and the reset spring 3213 work together to ensure that the abutment rod 3212 can make the pulley fit tightly and press against the upper surface of the lower mold 4 at a stable and downward angle, thereby reliably pushing the steel plate placed on it towards and positioning it at the mold axis. Moreover, the end of the limiting rod 328 away from the connecting ring 321 is rotatably connected to the middle position of the U-shaped rod 329 through the second connecting rod 3211. In this design, the limiting rod 328 is fixedly connected to the second connecting rod 3211 through its end away from the connecting ring 321, while the other end of the second connecting rod 3211 is rotatably connected to the middle position of the U-shaped rod 329. This makes the second connecting rod 3211 and the limiting rod 328 together form a rigid constraint frame for the movement of the U-shaped rod 329, providing a stable and definite rotation fulcrum for the lever movement of the U-shaped rod 329. When the second transmission rod 327 slides in the groove 3210 and pushes the U-shaped rod 329, the U-shaped rod 329 is forced to perform a precise rotational movement with the rotation connection point as the center, rather than uncontrollable translation or swaying.

[0023] In this embodiment, the lower mold 4 is precisely initially positioned by the support mechanism 31. The operator rotates the threaded rod 312 with a handle to make it move axially in the threaded pair with the support structure 311, thereby pushing the push plate 313, which is rotatably connected to it, to move forward in a straight line, and then pushing the lower mold 4 installed on its side to move on the support structure 311. At the same time, the scale rod 314 fixed to the push plate 313 moves with it and slides down the guide of the support structure 311. Its scale provides accurate displacement feedback, ensuring the initial centering accuracy. The inner connecting frame 315 fixed to the support structure 311 provides a stable base for the subsequent positioning mechanism 32. Furthermore, after the steel plate is placed, the positioning operation is initiated by manually moving the lever 325. The lever 325 drives the rotating ring 324 to rotate around the connecting shaft 323, converting the rotational motion into a thrust on the transmission rod 327 via the transmission rod 326. The transmission rod 327, constrained by the limiting rod 328 to linear motion, slides at its end in the groove 3210 of the U-shaped rod 329, converting this linear thrust into a thrust on one end of the U-shaped rod 329. This forces the U-shaped rod 329 to perform lever motion with the rotation fulcrum provided by the connecting rod 3211, causing its other end to extend outward and push the abutment rod 3212 and its end pulley to press against the upper surface of the lower mold 4. At this time, the obtuse angle structure between the U-shaped rod 329 and the abutment rod 3212, together with the reset spring 3213, ensures that the pulley presses the steel plate at a stable downward angle and reliably pushes it towards the mold axis. The rigid frame formed by the limiting rod 328 and the connecting rod 3211 completely restricts the motion freedom of the U-shaped rod 329, allowing it to perform precise fixed-axis rotation only.

[0024] Working principle: like Figures 1 to 5 As shown, during installation, the lower mold 4 is placed on the support structure 311, and then the position of the push plate 313 is adjusted by rotating the threaded rod 312 with a handle, and the adjustment is made by the scale of the ruler rod 314. The push plate 313 pushes the lower mold 4 to complete the position adjustment of the lower mold 4. In use, the steel plate for making the conical head is placed on the lower mold 4. Then, the lever 325 is moved, which drives the transmission rod 326 to move via the rotating ring 324. The transmission rod 326 then pushes the transmission rod 327 to extend. When the transmission rod 327 extends, the U-shaped rod 329 is limited by the connecting rod 3211, allowing the end of the transmission rod 327 away from the transmission rod 326 to slide within the groove 3210, thus driving the U-shaped rod 329. The lever movement causes the U-shaped rod 329 to drive the abutment rod 3212 to fit against the upper side of the lower mold 4, and pushes the steel plate of the conical head to the axis of the lower mold 4, so that the axis of the steel plate of the conical head overlaps with the axis of the lower mold 4. Then, the lever 325 is moved in the opposite direction to move the abutment rod 3212 away from the lower mold 4. The abutment rod 3212 is reset under the action of the reset spring 3213, thus completing the positioning adjustment of the steel plate of the conical head. Then, the steel plate of the conical head can be shaped.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
