Description

A billet piercing machine and piercing method for titanium tube production

Technical Field

The invention relates to the technical field of titanium tube perforation, and more particularly to a blank perforator and a perforation method thereof for titanium tube production.

Background Art

Titanium tubes are light in weight, high in strength and have excellent mechanical properties. They are widely used in heat exchange equipment, such as shell-and-tube heat exchangers, coil heat exchangers, serpentine heat exchangers, condensers, evaporators and transmission pipelines. Many nuclear power industries use titanium tubes as standard tubes for their units.

At present, the production of titanium tubes can be roughly divided into two processes: titanium tube suturing process and hot rolling perforation process. Among them, the titanium tube produced by the hot rolling perforation process is made of a whole piece of metal billet, with no traces of seams on the surface and a hollow cross-section. It is widely used in pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water and certain solid materials; titanium tubes need to be hot rolled during the production process, and the most important step in the hot rolling process is perforation.

In the prior art, the specific steps of the hot-rolled perforation process of titanium tubes are as follows: first, a solid round steel billet is heated and softened, and then sent to an automatic brake tube machine. The softened steel is continuously rotated and advanced through the equipment, and a cavity is gradually formed inside the tube wall under the action of the rollers and the pointed conical head, thereby realizing the hot-rolled perforation process of titanium tubes.

However, the existing push rod is overall long, and one end is fixed when rotating, while the other end rotates and extrude the softened steel billet through the mandrel. During the contact and extrusion process with the continuously rotating and advancing steel billet, the softened steel billet will generate centrifugal force due to the rotation of the push rod, causing the steel billet to produce a large degree of circumferential shaking around the outer wall of the push rod, thereby reducing the accuracy of the titanium tube perforation, thereby reducing the efficiency of the titanium tube perforation, and further reducing the quality of titanium tube production.

At the same time, after the existing head end penetrates the terminal end of the billet, it will be directly pulled out from the inside of the billet, and will not continue to extrude and expand the inner diameter of the terminal end of the billet, which will cause the inner wall of the terminal end of the billet to be different from the inner wall diameter of the initial end, thereby affecting the production quality of the titanium tube; if the piercing time is long, the inner wall diameter of the initial end of the billet will become larger and larger due to the centrifugal force, while the terminal end will have a larger and larger difference from the inner wall diameter of the initial end due to the lack of continued extrusion and hole expansion, which is more detrimental to the production quality of the titanium tube; for this reason, a billet piercing machine and a piercing method for titanium tube production are proposed to improve the existing problems.

A billet perforation method for titanium tube production, using the billet perforation machine for titanium tube production as described above, comprises the following steps:

S1. After the softened steel billet is clamped and fixed by the clamping member, on the one hand, the conveying motor is started, and its output end drives the conveying shaft to rotate, so that the conveying block moves linearly, and drives the conveying plate and the vertical plate to move synchronously, so that the steel billet gradually approaches the shaping chamber; on the other hand, the driving motor is started, and its output end drives the driving shaft to rotate, so that the driving block moves linearly, and drives the driving plate and the perforating shaft to move synchronously, so that the perforating shaft gradually approaches the shaping chamber;

S2. When the steel billet is hot rolled, on the one hand, the rotary cylinder is started, and its rotating end drives the rotary insert, the clamping piece and the steel billet to rotate, so that the steel billet rotates while approaching the shaping chamber; in this process, the shaping motor is started, and its output end drives the shaping die to rotate, so that while the steel billet itself rotates, the outer wall of the steel billet can be shaped by the rotating extrusion of the shaping die;

S3. On the other hand, the perforating motor is started, and its output end drives the small transmission wheel to rotate, and the large transmission wheel rotates synchronously through the transmission belt, and drives the fixed sleeve and the perforating shaft to rotate, so that the perforating shaft also rotates while approaching the shaping chamber, and gradually squeezes the inner wall of the billet to form a cavity through the tapered end of the perforating shaft;

S4. When the perforating shaft approaches the billet, its tapered end will pass through the center hole of the anti-sway component; during the hot rolling of the billet, the hot-rolled billet will gradually approach the anti-sway component, and then the anti-sway component will start to clamp the outer wall of the billet; then the electric slider will start, driving the slider and the anti-sway component to slide along the distribution direction of the slide rail, so that the anti-sway component will slide synchronously with the direction of the billet displacement, fixing the billet on a horizontal line;

S5. After the tapered end of the piercing shaft penetrates the steel billet, the driving motor will continue to push the driving block to make a linear motion, so that the piercing shaft continues to rotate and move forward. Then, the adaptive part starts. On the one hand, it stretches the inner wall of the terminal end of the steel billet and clamps the inner wall of the terminal end of the steel billet; on the other hand, it can drive the inner wall of the terminal end of the steel billet to make a circular motion along the outer wall of the piercing shaft, so that the inner wall of the terminal end of the steel billet has the same diameter as the inner wall of the initial end.

In summary, the present application includes at least one of the following beneficial technical effects:

(1) The corresponding rotating rod is driven to rotate by the anti-sway motor. Since the gear rings can mesh and transmit, the two rotating rods will drive the corresponding anti-sway plates to approach each other, clamp the outer wall of the billet, and make the billet rotate and displace horizontally, thus avoiding the problem that the softened billet generates centrifugal force due to the rotation of the perforation shaft, causing the billet to produce a large circumferential swing around the outer wall of the perforation shaft, thereby ensuring the accuracy of titanium tube perforation, improving the efficiency of titanium tube perforation, and further improving the production quality of titanium tube.

(2) The outer wall of the steel billet is clamped and limited by the anti-sway parts; the electric slider drives the slide plate and the anti-sway parts to slide along the distribution direction of the slide rail, so that the anti-sway parts slide synchronously with the displacement direction of the steel billet, and the steel billet is fixed on a horizontal line, thereby avoiding the problem that the softened steel billet generates centrifugal force due to the rotation of the perforation shaft, causing the steel billet to generate a large circumferential shaking around the outer wall of the perforation shaft, thereby ensuring the accuracy of the titanium tube perforation, improving the efficiency of the titanium tube perforation, and further improving the production quality of the titanium tube.

(3) The adjusting motor drives the adjusting gear to rotate. Since the adjusting gear can mesh with the adjusting block for transmission, the adjusting bar can slide in the adjusting groove, so that the adjusting bar drives the extension bar, the horizontal bar and the adjusting roller to approach the outer wall of the billet and clamp the outer wall of the billet; then, the electric ring block is started to drive the corresponding rotating bar to slide in the circumferential direction in the ring groove, and drive the billet to make a circular motion around the outer wall of the perforating shaft, so that the inner wall diameter of the terminal end of the billet is the same as that of the initial end, avoiding the problem that the inner wall diameter of the initial end of the billet will become larger and larger due to the action of centrifugal force, while the inner wall diameter of the terminal end will become larger and larger due to the lack of continued extrusion and expansion, thereby improving the production quality of titanium tubes and further improving the production efficiency of titanium tubes.

On the other hand, the inner wall of the terminal end of the billet can be clamped, and the billet can be driven to make a circular motion around the outer wall of the perforation shaft 355, so that the inner wall diameter of the terminal end of the billet is the same as that of the initial end, thereby avoiding the problem that the inner wall diameter of the initial end of the billet becomes larger and larger due to the centrifugal force, while the inner wall diameter of the terminal end becomes larger and larger due to the lack of continuous extrusion and expansion, thereby improving the production quality of the titanium tube and further improving the production efficiency of the titanium tube.

The function of the punching unit 3 is, on the one hand, to adjust the position of the punching shaft 355 so that the punching shaft 355 is aligned with the extrusion space in the middle of the shaping die 231; on the other hand, the punching shaft 355 can be rotated while being displaced closer to the billet, so as to achieve the purpose of punching the billet.

Embodiment 3: Through the technical solutions of Embodiment 1 and Embodiment 2, although the problem that the inner wall diameter of the initial end of the billet becomes larger and larger due to the centrifugal force, and the inner wall diameter of the terminal end becomes larger and larger due to the lack of further extrusion and hole expansion, it still does not solve the problem that the softened billet generates centrifugal force due to the rotation of the push rod, causing the billet to have a large circumferential shaking around the outer wall of the push rod. Therefore, the following solution is proposed:

Referring to FIGS. 7-9 , further, both ends of the transmission roller 251 are connected to the top of the carrier frame 25 through bearing seats, and the transmission chains 253 are staggered; the side of the electric slider 272 away from the slide rail 271 can be connected to the bottom of the slide plate 273 .

Since the gear rings 283 can mesh and transmit, the two rotating rods 282 will drive the corresponding anti-sway plates 284 to approach each other, clamp the outer wall of the steel billet, and make the steel billet rotate and displace in the horizontal direction, thereby avoiding the problem that the softened steel billet generates centrifugal force due to the rotation of the perforation shaft 355, causing the steel billet to generate large circumferential shaking around the outer wall of the perforation shaft 355, thereby ensuring the accuracy of the titanium tube perforation, improving the efficiency of the titanium tube perforation, and then improving the production quality of the titanium tube.

During this process, the anti-sway plate 284 will drive the corresponding first turning bar 285 to rotate. Since the second turning bar 286, the third turning bar 287, the fourth turning bar 288 and the fifth turning bar 289 are all connected by connecting rods, the fifth turning bar 289 can drive the height limiting plate 29 to slide along the arc groove 2841 through the arc bar 291, so that the two height limiting plates 29 are close to each other, limiting the height of the steel billet, so that the shaking height of the steel billet cannot exceed the height limiting plate 29, thereby ensuring the stability of the steel billet.

On the other hand, the perforating motor (35) is started, and its output end drives the small transmission wheel (351) to rotate, and the large transmission wheel (352) rotates synchronously through the transmission belt (353), and drives the fixed sleeve (354) and the perforating shaft (355) to rotate, so that the perforating shaft (355) also rotates while approaching the shaping chamber (22), and the inner wall of the billet is gradually squeezed to form a cavity through the tapered end of the perforating shaft (355); S4, when the perforating shaft (355) approaches the steel billet, its tapered end will pass through the center hole of the anti-sway member (28); during the hot rolling of the steel billet, the hot-rolled steel billet will gradually approach the anti-sway member (28), and then the anti-sway member (28) will start to clamp and limit the outer wall of the steel billet; then the electric slider (272) will start to drive the slide plate (273) and the anti-sway member (28) to slide along the distribution direction of the slide rail (271), so that the anti-sway member (28) will slide synchronously with the direction of displacement of the steel billet, and the steel billet will be fixed on a horizontal line; S5. After the conical end of the perforating shaft (355) has penetrated the steel billet, the driving motor (32) will continue to push the driving block (322) to make a linear motion, so that the perforating shaft (355) continues to rotate and move forward. Then, the adaptive member (24) is started. On the one hand, the inner wall of the terminal end of the steel billet is stretched open and the inner wall of the terminal end of the steel billet is clamped; on the other hand, the inner wall of the terminal end of the steel billet is driven to make a circular motion along the outer wall of the perforating shaft (355), so that the inner wall of the terminal end of the steel billet has the same diameter as the inner wall of the initial end.
