Description

Technical Field

[0001] The utility model relates to the technical field of head processing, in particular to a spinning device for processing conical heads. Background Technique

[0002] The head is an essential and important component in pressure vessel equipment in many industries such as petrochemical, atomic energy, food, and pharmaceutical industries. A head refers to a component used to close the end of a container to isolate the internal and external media, also known as an end cover. The heads of cylindrical containers are generally rotating shells. According to the surface shape of the head, it can be divided into convex, conical, flat, and combined shapes. A convex head refers to a head with a convex outer surface, such as a hemispherical, elliptical, dish-shaped, and non-flanged spherical head, etc. The processing and forming methods of heads mainly include hammering, stamping, and spinning methods. Among them, the processing of the spinning method mainly uses a spinning machine to spin and form.

[0003] For example, the Chinese patent with the publication number CN217912371U discloses a high-strength conical head forming device, including a frame. A base is provided at the bottom end of the frame. An operating table is provided at the upper end of one side of the frame. An electrical box is provided at the lower end of the operating table. An upper connecting seat is provided at one side of the upper end of the frame. One end of the upper connecting seat is fixedly connected to the frame. An upper pressing device is provided on the connecting seat. A lower pressing device is provided on the frame at a position corresponding to the connecting seat. A spinning device is also provided on the frame. The spinning device includes an inner spinning device and an outer spinning device. The conical head is spun and formed by a spinning machine. The conical head is integrally formed through the inner and outer spinning devices, and the strength is relatively high.

[0004] This patent sets an upper pressing device and a lower pressing device. Both the upper and lower pressing devices can move up and down and left and right, and can clamp and fix heads of different sizes, effectively avoiding the shaking of the head and strengthening the stability of the head. However, only the pressing cylinder and the lower support seat are used to position the middle part of the head, and the contact area is limited, resulting in unstable fixation. The head will shake during the rotation process, which may cause the head to deform during the spinning process, thereby affecting the spinning effect. At the same time, during processing, the pressing cylinder drives the pressing block to move, so that the pressing block abuts against the inner wall of the head to fix the head. Since there are many different cone angles corresponding to different conical heads, different pressing blocks need to be prepared according to different cone angles, and the actual production volume and demand for some cone angles are relatively small, resulting in a relatively high cost investment.

A positioning assembly 2 for clamping and fixing the conical head 100 is provided on the frame 1. A pressing assembly 3 is arranged above the positioning assembly 2. The positioning assembly 2 and the pressing assembly 3 are slidable relative to the frame 1. A spinning assembly 4 is arranged on one side of the frame 1 where the positioning assembly 2 and the pressing assembly 3 are located.

[0029] As Figure 1 、 3 shown, in this embodiment, the positioning assembly 2 includes a rotating plate 21 and a rotation driving member 22. The rotation driving member 22 is slidably installed on the frame 1. The rotating plate 21 is fixedly installed at the output end of the rotation driving member 22. Specifically, a sliding groove 11 is formed on the frame 1. A slidable sliding plate 12 is arranged in the sliding groove 11. The rotation driving member 22 is fixedly installed on the sliding plate 12. A lead screw 13 is rotatably installed in the sliding groove 11. The sliding plate 12 is in threaded connection with the lead screw 13. A transmission motor 14 for driving the lead screw 13 to rotate is fixedly arranged on the frame 1. When the transmission motor 14 drives the lead screw 13 to rotate, the sliding plate 12 in threaded connection with the lead screw 13 moves in the sliding groove 11.

[0030] In this embodiment, the rotation driving member 22 can be a driving motor or a driving motor.

[0031] As Figure 1 、 3 shown, in this embodiment, in order to ensure the smoothness of the sliding of the sliding plate 12, sliding strips 15 are fixedly arranged on two opposite side walls of the sliding groove 11. Sliding grooves corresponding to the sliding strips 15 are formed on both sides of the sliding plate 12. When the lead screw 13 drives the sliding plate 12 to slide, the sliding plate 12 can slide on the sliding strips 15 through the sliding grooves on both sides, thereby ensuring the stability of the sliding of the sliding plate 12. At the same time, the sliding strips 15 and the sliding grooves are arranged to play a guiding role in the sliding of the sliding plate 12.

[0032] As Figure 1 、 2As shown in FIGS. 3 and 4, in this embodiment, the positioning assembly 2 further includes a lifting cylinder 23 and a positioning plate 24. The lifting cylinder 23 is fixedly installed on the rotating plate 21 of the rotating assembly, and the positioning plate 24 is fixedly installed on the output end of the lifting cylinder 23. A plurality of positioning bars 25 are rotatably installed on the positioning plate 24, and the positioning bars 25 are evenly distributed along the circumferential direction of the positioning plate 24.

An elastic gasket 29 is fixedly provided at the end of the contact bolt 28 on the side close to the positioning bar 25. By rotating the contact bolt 28, the elastic gasket 29 at the end of the contact bolt 28 abuts against the outer wall of the conical cone head, so that the conical cone head can be fixed, facilitating the spinning operation. The rotatable positioning bars 25 are provided on the positioning plate 24, so that regardless of the size of the cone head, the positioning bars 25 can always abut against the inner wall of the cone head, and thus are applicable to cone heads of different sizes.

The conical head is moved downward, and the positioning strip 25 rotates. The positioning strip 25 always fits against the inner wall of the conical head until the lower end of the conical head abuts against the support strip 26. The abutting bolt 28 is rotated so that the elastic gasket 29 at the end of the abutting bolt 28 abuts against the outer wall of the conical conical head, so that the conical head can be fixed on the support strip 26 and the positioning strip 25; the lifting cylinder 23 drives the positioning plate 24 to move up and down, so that the positioning plate 24 and the positioning strip 25 drive the conical head to move up and down to adjust the working position during spinning; the pressing cylinder 31 drives the pressing block 32 to move downward so that the pressing block 32 abuts against the positioning plate 24 to further fix the conical head; the driving motor 14 drives the lead screw 13 to rotate, so that the sliding plate 12 threadedly connected to the lead screw 13 moves, and then the conical head moves towards the spinning assembly 4 to reach the spinning position; the forming cylinder 43 and the spinning cylinder 44 drive the forming roller 41 and the spinning roller 42 to move respectively, so that the forming roller 41 and the spinning roller 42 are respectively abutted against the outer wall and the inner wall of the conical head; the rotating assembly drives the conical head to rotate. During the rotation of the conical head, the forming cylinder 43 and the spinning cylinder 44 drive the forming roller 41 and the spinning roller 42 to move continuously, so that the forming roller 41 and the spinning roller 42 are always abutted against the outer wall and the inner wall of the conical head, and the spinning of the conical head is completed.
