Description

Technical Field

[0001] This utility model relates to the field of round steel preparation technology, specifically to a device for preparing impact-resistant special alloy round steel. Background Technology

[0002] The impact-resistant special alloy round steel preparation device is a specialized industrial equipment. Its core function is to process special alloy raw materials (such as alloy billets containing impact-resistant elements such as chromium, nickel, and molybdenum) into round steel profiles with high toughness and impact resistance through processes such as melting, forging, rolling, and heat treatment.

[0003] For example, the patent application "CN120791546A" discloses a manufacturing apparatus and method for ultra-thin-walled seamless steel pipes. This apparatus uses a centering clamping component to coaxially clamp irregularly shaped ultra-thin-walled seamless steel pipes of different diameters and with one end thicker than the other with a grinding mechanism. The grinding assembly's support sleeve, support rod, and other components work together to drive the grinding block to adapt to changes in the inner wall diameter, meeting diverse grinding needs. Traditional impact-resistant special alloy round steel preparation devices employ a self-pressurized extrusion die design. The material relies on its own pressure to propel it. The extruded round steel is subject to gravity, resulting in radial sagging and axial bending deformation. This deformation is particularly pronounced when preparing large-diameter or ultra-long round steel, directly leading to out-of-tolerance dimensional accuracy and insufficient surface flatness, severely affecting the product's mechanical properties and reliability. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional impact-resistant special alloy round steel preparation devices rely on extrusion molds for self-pressurized discharge, and the round steel is prone to sagging and deformation at the discharge port due to gravity. Therefore, an impact-resistant special alloy round steel preparation device is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design an impact-resistant special alloy round steel preparation device, including a base and a box. The box is fixedly connected to the upper right side of the base. A feed port is opened on the upper right side of the box. The left end of the box is fixedly connected to a material gathering tube. The left end of the material gathering tube is fixedly connected to a cylinder. The base and the inner wall of the block are both connected by bolt threads. The outer wall of the block is provided with a mold disassembly structure.

[0006] This setting block is mounted on the base using bolts.

[0007] Preferably, the mold disassembly structure includes a mold, the upper end of the block is fixedly connected to the mold, the inner wall of the mold is machined with a round tube, the upper and lower sides of the right end of the mold are fixedly connected with straight plates, the outer wall of the straight plate is slidably connected to a groove, and the inner wall of the cylinder is provided with a groove.

[0008] This feature facilitates mold replacement, as different molds produce round tubes of different diameters, thus accommodating round steel bars of various diameters.

[0009] Preferably, the right end of the housing is threadedly connected to the second servo motor via bolts, and the output shaft of the second servo motor is fixedly connected to the screw rod.

[0010] In this configuration, the second servo motor is mounted on the housing using bolts.

[0011] Preferably, the left end of the mold is provided with an anti-sagging structure.

[0012] Preferably, the anti-sagging structure includes a first vertical plate and a second vertical plate. Multiple first vertical plates are fixedly connected to the lower left side of the mold. The inner wall of the first vertical plate is rotatably connected to the first roller through a sealed bearing. The outer wall of the first vertical plate is threadedly connected to the first servo motor through bolts. The output shaft of the first servo motor is fixedly connected to the first roller on the right side. Multiple second vertical plates are fixedly connected to the upper left side of the mold. The inner wall of the second vertical plate is rotatably connected to the second roller through a sealed bearing.

[0013] This setting prevents the round steel bars from sagging during discharge.

[0014] Preferably, the outer wall of the spiral rod is rotatably connected to the housing via a sealed bearing.

[0015] This setting allows the screw rod to rotate within the housing via a sealed bearing.

[0016] The present invention proposes an impact-resistant special alloy round steel preparation device, the advantages of which are as follows: through the cooperation of the anti-sagging structure and the mold, the output shaft of the first servo motor drives the first round roller on the right to rotate. Due to the friction generated by the contact between the first round roller and the round steel, combined with the adhesion between the round steel and the second round roller, the first round roller and the second round roller rotate synchronously, forming a stable conveying power system. At this time, the distance between the first round roller and the second round roller is preset to a size that matches the diameter of the round tube, providing precise radial limit for the round steel. After the round steel prototype is discharged from the left end of the round tube, it immediately enters the clamping area between the first round roller and the second round roller supported by the first vertical plate and the second vertical plate. The first round roller below offsets the weight of the round steel itself through the upward supporting force, effectively avoiding radial sagging and axial bending deformation of the round steel due to gravity after discharge.

The outer wall of the block 6 is provided with a mold disassembly structure 5. The right end of the housing 2 is threadedly connected to the second servo motor 8 by bolts. The second servo motor 8 is mounted on the housing 2 by bolts. The second servo motor 8 is externally powered by a power supply (not marked in the figure) and is equipped with control buttons and a circuit system for starting and stopping the second servo motor 8. The output shaft of the second servo motor 8 is fixedly connected to the screw rod 9. The rotation of the output shaft of the second servo motor 8 drives the screw rod 9 to rotate. The left end of the mold 503 is provided with an anti-sagging structure 7. The outer wall of the screw rod 9 is rotatably connected to the housing 2 through a sealed bearing. The screw rod 9 rotates inside the housing 2 through the sealed bearing.

[0020] See attached document Figure 1-4The mold disassembly structure 5 includes a mold 503. The upper end of a block 6 is fixedly connected to the mold 503, and the block 6 plays a role in fixing the mold 503. The inner wall of the mold 503 is machined with a round tube 504. Different models of round tubes 504 correspond to various sizes of round steel. The upper and lower sides of the right end of the mold 503 are fixedly connected with straight plates 502, and the mold 503 plays a role in fixing the straight plates 502. The outer wall of the straight plate 502 is slidably connected to the groove 501, and the straight plate 502 slides in the groove 501. The inner wall of the cylinder 4 is provided with a groove 501. First, the equipment is pre-assembled and the mold is adapted. According to the target diameter of the round steel to be processed, a mold 503 with a corresponding size round tube 504 processed on the inner wall is selected. The straight plate 502, which is fixedly connected to the upper and lower sides of the right end of the mold 503, is aligned with the groove 501 opened on the inner wall of the cylinder 4 and inserted. After ensuring that the straight plate 502 and the groove 501 slide and fit in place, the straight plate 502 and the cylinder 4 are locked and fixed with bolts to complete the sealed connection between the mold 503 and the cylinder 4. Then, the block 6 is installed in the preset position of the base 1 with bolts. The fixed connection between the block 6 and the mold 503 is used to achieve stable support of the mold 503.

[0021] See attached document Figure 1 , Figure 2 and Figure 5 The anti-sagging structure 7 includes a first vertical plate 701 and a second vertical plate 704. Multiple first vertical plates 701 are fixedly connected to the lower left side of the mold 503. The mold 503 fixes the multiple first vertical plates 701. The inner wall of the first vertical plate 701 is rotatably connected to the first roller 702 through a sealed bearing. The first roller 702 rotates inside the first vertical plate 701 through the sealed bearing. The outer wall of the first vertical plate 701 is threadedly connected to the first servo motor 703 through bolts. The first servo motor 703 is installed on the first vertical plate 701 through bolts, which facilitates subsequent disassembly and maintenance. The first servo motor 703 is externally powered by a power source (not shown in the figure) and is equipped with control buttons and a circuit system for starting and stopping the first servo motor 703. The output shaft of the first servo motor 703 is fixedly connected to the first circular roller 702 on the right side. The rotation of the output shaft of the first servo motor 703 drives the first circular roller 702 on the right side to rotate. Multiple second vertical plates 704 are fixedly connected to the upper left side of the mold 503. The mold 503 fixes the second vertical plates 704. The inner wall of the second vertical plate 704 is rotatably connected to the second circular roller 705 through a sealed bearing. The second circular roller 705 rotates inside the second vertical plate 704 through the sealed bearing. The output shaft of the first servo motor 703 drives the first circular roller 702 on the right side to rotate. Due to the friction generated by the contact between the first circular roller 702 and the round steel, combined with the contact between the round steel and the second circular roller 705, the first circular roller 702 and the second circular roller 705 are driven to rotate synchronously, forming a stable conveying power system. At this time, the distance between the first circular roller 702 and the second circular roller 705 has been preset to a size that matches the diameter of the circular tube 504, providing precise radial limit for the round steel.

[0022] Working principle: When using the equipment for preparing impact-resistant special alloy round steel: First, the equipment is pre-assembled and the mold is adapted. According to the target diameter of the round steel to be processed, a mold 503 with a corresponding size round tube 504 processed on the inner wall is selected. The straight plate 502, which is fixedly connected to the upper and lower sides of the right end of the mold 503, is aligned with the groove 501 opened on the inner wall of the cylinder 4 and inserted. After ensuring that the straight plate 502 and the groove 501 slide and fit in place, the straight plate 502 and the cylinder 4 are locked and fixed with bolts to complete the sealed connection between the mold 503 and the cylinder 4. Then, the block 6 is installed in the preset position of the base 1 with bolts. The fixed connection between the block 6 and the mold 503 is used to achieve stable support of the mold 503.

[0023] When the external power supply of the second servo motor 8 and the first servo motor 703 is connected, the second servo motor 8 and the first servo motor 703 are turned on simultaneously. The output shaft of the second servo motor 8 drives the screw rod 9 to rotate stably inside the housing 2 through the sealed bearing. The rotation speed of the screw rod 9 can be precisely controlled by the servo system. The output shaft of the first servo motor 703 drives the first circular roller 702 on the right side to rotate. Due to the friction generated by the contact between the first circular roller 702 and the round steel, combined with the contact between the round steel and the second circular roller 705, the first circular roller 702 and the second circular roller 705 are driven to rotate synchronously, forming a stable conveying power system. At this time, the distance between the first circular roller 702 and the second circular roller 705 has been preset to a size that matches the diameter of the circular tube 504, providing precise radial limit for the round steel.

[0024] During the material forming and conveying process, the molten impact-resistant special alloy raw material is poured into the box 2 through the feed port 10. The rotating screw rod 9 pushes the molten raw material to the left through the screw blades, generating a stable thrust during the process. The raw material is uniformly conveyed to the material collection pipe 3 for temporary storage and collection, ensuring a continuous and stable supply of materials. Under the continuous thrust of the screw rod 9, the molten raw material in the material collection pipe 3 enters the circular tube 504 on the inner wall of the mold 503. With the help of the cavity constraint of the circular tube 504, the initial shaping is completed, forming a round steel prototype that meets the diameter requirements.

[0025] After the round steel prototype exits from the left end of the round tube 504, it immediately enters the clamping area between the first round roller 702 and the second round roller 705, which are supported by the first vertical plate 701 and the second vertical plate 704. The lower first round roller 702 counteracts the weight of the round steel by providing upward support, effectively preventing the round steel from radially sagging and axially bending after exiting the material. The upper second round roller 702, together with the lower first round roller 702, forms a bidirectional limit, further ensuring the flatness and dimensional accuracy of the round steel surface. Under the rotational driving force of the first round roller 702, the formed round steel is smoothly conveyed to the left and directly enters the next process, thus completing the workflow of the impact-resistant special alloy round steel preparation device.
