Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of for with tooling annealing spool, belong to metal wire processing field. BACKGROUND

[0002] Metal wire is prepared by drawing method, in addition to heat drawing process, it is often necessary to carry out intermediate annealing and finished product annealing. Its purpose is to eliminate the work hardening caused by the previous drawing process, reduce the strength, restore plasticity, so as to facilitate subsequent drawing process or customer use;For titanium wire product, finished product annealing also has the purpose of dehydrogenation.

[0003] The most common annealing method is to coil the wire into a roll and then anneal it in the furnace. Currently, the industry's common practice is to bend the wire into a circle using a reel or other take-up mechanism during the drawing process, and then collect it into a loose coil. Alternatively, a detachable spool can be used, and the wire is wound into a disc circle on the spool during drawing. After being tied and fixed, the disc circle is removed from the detachable spool, resulting in a hollow disc circle with a tight arrangement or close to a tight arrangement. Whether the loose coil and hollow disc circle obtained by either method is securely tied, deformation may occur during annealing. Deformation of the loose coil or hollow disc circle includes local collapse caused by material softening at high temperature, sliding between the upper and lower layers due to the failure of the tie caused by the reduction of height at high temperature, and changes in the diameter and shape of the disc circle. Regardless of the type of deformation, the annealed loose coil or disc circle may affect the subsequent drawing process. Deformed loose coils are difficult to automatically unwind and often require manual intervention. After annealing, the hollow disc circle removed from the detachable spool is difficult to reassemble into the detachable spool for unwinding due to deformation.

[0004] Metal wire, especially titanium wire and other metals with poor plasticity, requires multiple annealing during the drawing process. Tying before annealing and unwinding or reassembling on the spool after annealing is extremely labor-intensive. Currently, wire drawing processing has a high degree of automation in the drawing and annealing processes, but the take-up and unwinding processes have become a bottleneck that restricts further improvement in automation, resulting in low overall efficiency and high labor costs. In addition, for wire annealing, especially finished product annealing, heat treatment deformation causes local "dead bends" in the disc wire, making it difficult to straighten.

[0005] From the perspective of improving wire drawing efficiency and preventing wire deformation, using a spool for take-up and unwinding is very beneficial. The most convenient way is to anneal the wire with a spool in the furnace. However, the commonly used spools are difficult to use for furnace annealing due to their poor heat resistance, which causes the spool to deform after being placed in the furnace. A D800 spool weighs more than 100 kg, absorbs more heat, significantly increases the energy consumption of heat treatment, and has a large heat capacity, limiting the heating rate of heat treatment. SUMMARY

[0006] The technical problem to be solved by this utility model is that the existing H-beam wheels have a large mass and absorb a lot of heat, which increases the energy consumption of heat treatment and limits the heating rate of heat treatment.

[0007] The technical solution adopted by this utility model to solve its technical problem is: an I-beam wheel for annealing with tooling, including an outer cylinder and an inner support body. The outer cylinder is provided with an outer cylinder top plate and an outer cylinder bottom plate at both ends, and the inner support body is provided with a support top plate and a support bottom plate at both ends, so that the projection of the outer cylinder and the inner support body is an I-beam structure. The middle part of the inner support body is inserted into the outer cylinder, and the support top plate is detachably connected to the outer cylinder top plate, and the support bottom plate is detachably connected to the outer cylinder bottom plate.

[0008] The inner support body in the above structure includes several support rods. Each support rod has a threaded connection at both ends and is threaded to the top support plate and the bottom support plate, respectively.

[0009] Furthermore, the support rods in the above structure are arranged in a two-layer circular structure, with the outer layer consisting of 6 to 18 support rods and the inner layer consisting of 6 to 12 support rods.

[0010] Furthermore, the above structure also includes a reinforcing plate, which has the same cross-section as the middle section of the outer cylinder, and is provided with several through holes at intervals. The support rod passes through the through holes and is connected and fixed to the reinforcing plate.

[0011] Furthermore, the reinforcing plates described in the above structure consist of 1 to 3 pieces.

[0012] In the above structure, the taper value inside the outer cylinder is 1:300 to 1:50, and the smaller end of the inner diameter of the outer cylinder is close to the bottom plate of the outer cylinder.

[0013] Furthermore, the outer cylinder material described in the above structure is heat-resistant steel or high-temperature alloy.

[0014] In the above structure, the outer cylinder top plate and supporting top plate, and the outer cylinder bottom plate and supporting bottom plate are all connected by bolts.

[0015] The outer cylinder described in the above structure is a circular hollow cylinder with a wall thickness of 5-20mm; the bottom plate and top plate of the outer cylinder are both hollow rings, and the thickness of the bottom plate of the outer cylinder is 5-30mm, and the thickness of the top plate of the outer cylinder is 5-20mm.

[0016] In the above structure, the wall thickness of the supporting base plate is 5-20mm, the diameter of the supporting rod is 5-20mm, the thickness of the supporting top plate is 10-30mm, and the thickness of the reinforcing plate is 20-40mm.

[0017] The beneficial effects of this invention are as follows: This structure can be used for both annealing with tooled I-beams and wire drawing. Using this structure enables annealing with tooling, reducing the time spent on pre-annealing bundling and post-annealing reinstallation of the I-beams, reducing the difficulty of wire feeding, significantly improving the automation rate of wire production, reducing manual labor, and increasing production efficiency. Furthermore, it reduces wire deformation during heat treatment and lowers the difficulty of the straightening process. Simultaneously, this structure employs a two-layer structure of an outer cylinder and an inner support. During heat treatment, the inner support can be removed, leaving the outer cylinder and metal wire for furnace heat treatment, reducing structural weight and effectively avoiding the disadvantages of a complete heat-resistant steel I-beam, such as high weight, high annealing energy consumption, and high cost.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 5As shown, this utility model discloses an I-beam wheel for annealing with tooling, comprising an outer cylinder 2 and an inner support 4. The outer cylinder 2 has an outer top plate 22 and an outer bottom plate 21 at both ends, and the inner support 4 has a supporting top plate 1 and a supporting bottom plate 43 at both ends, forming an I-beam structure. The inner support 4 is inserted into the outer cylinder 2 at its center, and the supporting top plate 1 is detachably connected to the outer top plate 22, and the supporting bottom plate 43 is detachably connected to the outer bottom plate 21. Those skilled in the art will understand that this structure employs a two-layer nested design, specifically including an outer cylinder 2 and an inner support 4, with the inner support 4 inserted into the outer cylinder 2 at its center, so that the center of the inner support 4 is close to the inner wall of the outer cylinder 2 at its center. The supporting top plate 1 is detachably connected to the outer top plate 22, and the supporting bottom plate 43 is detachably connected to the outer bottom plate 21. The outer cylinder bottom plate 21 and outer cylinder top plate 22 can be integrally cast with the outer cylinder body 2, or they can be manufactured separately and then welded together to ensure structural strength. When used for wire drawing, the inner support body 4 is fitted into the outer cylinder body 2. The support top plate 1 and support bottom plate 43 of the inner support body 4 are detachably connected and fixed to the outer cylinder top plate 22 and outer cylinder bottom plate 21 of the outer cylinder body 2, combining the inner support body 4 and the outer cylinder body 2 into a complete H-beam wheel, increasing the overall structural strength. At this time, the inner support body 4 is used to strengthen the outer H-beam wheel, avoiding the deformation or even damage of the H-beam wheel due to insufficient rigidity during wire drawing and the load of the hundreds of kilograms of wire wrapped around it and the drawing force. Before annealing in the furnace, the I-beam can be erected, the inner support top plate 1 and the outer cylinder top plate 22 can be separated and removed, and the inner support body 4 and the support bottom plate 43 can be removed. The outer I-beam, composed of the outer cylinder 2, the outer cylinder bottom plate 21, and the outer cylinder top plate 22, is then fed into the furnace along with the metal wire wound on the outer cylinder 2 for heat treatment. Since the I-beam is in an upright state during annealing, the weight of the wire itself has no force on the cylinder; the weight of the wire acts on the outer cylinder bottom plate 21, reducing the weight of the I-beam, reducing the heat capacity of the I-beam, reducing the energy consumption of the annealing process, and allowing for a higher heat treatment heating rate.

[0026] Preferably, the inner support body 4 in the above structure includes a plurality of support rods 41. Each support rod 41 has threaded connection portions 411 at both ends, and both ends of the support rod 41 are threadedly connected to the top support plate 1 and the bottom support plate 43, respectively. Those skilled in the art will understand that, more preferably, the inner support body 4 includes a plurality of support rods 41 arranged in a circular shape, with both ends of the support rods 41 connected to the top support plate 1 and the bottom support plate 43, and more preferably, both ends of the support rods 41 have threaded connection portions 411, allowing the ends of the support rods 41 to be threadedly connected to the top support plate 1 and the bottom support plate 43, respectively.

[0027] Preferably, in the above structure, the support rods 41 form a two-layer circular structure, with the outer layer consisting of 6 to 18 support rods 41 and the inner layer consisting of 6 to 12 support rods 41. Those skilled in the art will understand that this structure is further preferably configured with a specific arrangement of the number and shape of the support rods 41, forming a two-layer circular structure, with the outer layer consisting of 6 to 18 support rods 41 and the inner layer consisting of 6 to 12 support rods 41, to ensure the structural strength of the inner support body 4.

[0028] Preferably, the above structure also includes a reinforcing plate 42. The reinforcing plate 42 has the same shape as the inner diameter of the middle part of the outer cylinder 2, and several through holes are provided on the reinforcing plate 42 at intervals. The support rod 41 passes through the through holes and is connected and fixed to the reinforcing plate 42. Those skilled in the art will understand that, in order to ensure the structural strength of the support rod 41, the reinforcing plate 42 is preferably circular with a thickness of 20-40mm, and its diameter should ensure that it fits snugly against the inner wall of the outer cylinder 2 after installation. Holes are made on the reinforcing plate 42, and the diameter of the holes matches the number and diameter of the support rods 41. The inner and outer rings of support rods 41 are respectively installed in the holes of the inner and outer rings of the reinforcing plate 42 and fixed by welding. The assembled inner support 4 should be sized to ensure that, after being inserted into the outer cylinder 2, its reinforcing plate 42 and outer support rods 41 fit snugly against the inner wall of the outer cylinder 2.

Those skilled in the art will understand that, since the I-beam is in a vertical state during annealing, the weight of the wire does not exert any force on the cylinder, but rather on the bottom plate 21 of the outer cylinder. Therefore, in order to maintain the structural strength of the outer cylinder 2, this structure preferably has a taper value inside the outer cylinder 2 of 1:300 to 1:50, and the smaller end of the inner diameter of the outer cylinder 2 is close to the bottom plate 21 of the outer cylinder.

[0031] Preferably, the outer cylinder 2 in the above structure is made of heat-resistant steel or a high-temperature alloy. Those skilled in the art will understand that, since the outer cylinder 2 is heat-treated in the furnace along with the metal wire, to prevent deformation under the pressure of the wire at high temperatures, the outer cylinder 2 is preferably made of heat-resistant steel or a high-temperature alloy. The inner support 4 is mainly used to reinforce the outer cylinder 2; to reduce costs, it is actually preferred that all components of the inner support 4 be made of carbon steel.

[0033] Preferably, in the above structure, the outer cylinder 2 is a circular hollow cylinder with a wall thickness of 5-20 mm; the outer cylinder bottom plate 21 and the outer cylinder top plate 22 are both hollow rings, and the thickness of the outer cylinder bottom plate 21 is 5-30 mm, and the thickness of the outer cylinder top plate 22 is 5-20 mm. Those skilled in the art will understand that this structure preferably uses a thinner outer cylinder and outer cylinder top plate 22, and hollows out the outer cylinder 2, outer cylinder top plate 22, and outer cylinder bottom plate 21, which will reduce the weight of the I-beam wheel, reduce the heat capacity of the I-beam wheel, reduce energy consumption in the annealing process, and allow for a higher heat treatment heating rate.

It includes 12 outer support rods 41 and 6 inner support rods 41, each with a diameter of 20mm and threaded ends. The support rods 41 are threaded to the base plate 43. It includes two reinforcing plates 42; each reinforcing plate 42 is circular and 30mm thick, with a diameter sufficient to ensure it fits snugly against the inner wall of the outer cylinder 2 after installation. Holes are drilled in the reinforcing plates 42, with the diameter matching the number and diameter of the support rods 41. The inner and outer rings of support rods 41 are installed in the holes of the inner and outer rings of the reinforcing plates 42, respectively, and fixed by welding. The assembled inner support body 4 should be sized to ensure that, after insertion into the outer cylinder 2, its reinforcing plates 42 and outer support rods 41 fit snugly against the inner wall of the outer cylinder 2. All components of the inner support body 4 are made of Q235 carbon steel.

[0041] The supporting top plate 1 is a circular ring with a thickness of 20mm. The supporting top plate 1 has an opening located at the same position as the reinforcing plate 42, and is threadedly connected to the supporting rod 41.
