Description

Technical Field

[0001] This utility model relates to the field of electric furnace ingot processing technology, and specifically to an electric furnace ingot processing device. Background Technology

[0002] With the continuous advancement of industrial technology, the working conditions for forgings are becoming increasingly demanding, and the working speed is constantly increasing, which places higher requirements on the precision of forgings. In order to improve production efficiency, reduce material consumption, cut product costs, and thus enhance product quality and market competitiveness, electric furnace ingots are receiving increasing attention from enterprises.

[0003] However, during the production of electric arc furnace ingots, problems such as improper design of the insulation riser, excessively high casting temperature, and excessively fast casting speed often lead to poor feeding effects, resulting in shrinkage cavities. Shrinkage cavities mainly appear at the center of the riser end of the electric arc furnace ingot, which severely damages the internal quality and mechanical properties of the ingot. If left untreated, the shrinkage cavity defect will continue to expand and extend into the interior of the ingot during subsequent continuous forging production, causing a significant reduction in yield and seriously affecting the compliance of later products with acceptable delivery dimensions.

[0004] To address this issue, existing technologies employ a method of extruding the riser from the electric furnace ingot and then drawing it out. This concentrates shrinkage defects in the extruded riser portion, which is then removed, thus improving the internal quality of the ingot and the subsequent yield. However, during the drawing process, if the deformation amount during each drawing is not properly controlled, the extruded riser portion can easily move into the interior of the ingot. Even after removing this riser portion, a significant number of shrinkage defects will remain inside the ingot, affecting product quality. Utility Model Content

[0005] To address the technical problem in existing technologies where, after extruding the riser of an electric furnace ingot, the deformation amount during each elongation cannot be properly controlled, and the extruded riser portion easily moves into the interior of the ingot, leaving numerous shrinkage cavities inside even after the riser is removed, thus affecting product quality, this invention provides an electric furnace ingot processing device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An electric furnace ingot processing device includes a riser extrusion mechanism and a chopping mechanism. The riser extrusion mechanism includes an upper flat anvil, with an upsetting disc connected to the bottom of the upper flat anvil. A disc is located below the upsetting disc, and an extrusion hole is opened in the center of the disc. The extrusion hole penetrates the disc along the axial direction of the disc, and the upper surface of the disc is concave towards the center. The chopping mechanism includes a clamp and a chopping knife. One side of the clamp has a clamping opening for holding the electric furnace ingot. The top of the clamp is connected to a hydraulic rod, which is vertically arranged. The chopping knife is located on the side of the clamp with the clamping opening. The chopping knife includes a knife holder, with a knife groove on the top of the knife holder. A knife body is installed in the knife groove, and the length of the knife body is greater than the diameter of the extrusion hole.

[0008] Using the above structural design, after the electric furnace ingot is upset by the riser extrusion mechanism, the riser portion is extruded. Then, the extruded riser portion is cut off by the chopping mechanism, discarding the smaller portion and preserving the larger portion, thus improving the internal quality of the electric furnace ingot and the subsequent yield. This also prevents the extruded portion from moving into the interior of the electric furnace ingot during the later drawing process. The upper surface of the disc of the riser extrusion mechanism is concave towards the center, which helps guide the riser portion to move towards the extrusion hole and facilitates the chopping mechanism in cutting off the extruded riser portion without damaging the surface of the remaining electric furnace ingot, reducing the difficulty of chopping.

[0009] As a preferred implementation of an electric furnace ingot processing device, the outer circumferential surface of the disc is connected to two oppositely arranged lifting lugs.

[0010] The above structural design facilitates the lifting and installation of the disc, and makes it easier to adjust and fix its position in the processing device, thus improving the convenience and operability of the device.

[0011] As a preferred implementation of an electric furnace ingot processing device, the side of the fixture opposite to the clamping opening is connected to a sliding sleeve, the sliding sleeve is slidably sleeved on the outside of the sliding rod, and the sliding rod is vertically set.

[0012] With the above structural design, the side of the fixture opposite to the clamping opening is connected to the slide rod through a sliding sleeve. The sliding sleeve can slide outside the slide rod, making the vertical movement of the fixture more stable and accurate. This ensures the positional accuracy of the electric furnace ingot during clamping and chopping, which is beneficial to improving processing quality.

[0013] As a preferred implementation of an electric furnace ingot processing device, the fixture includes a clamping block one, the top of which is connected to a hydraulic rod, and the bottom of the clamping block one is connected to a vertically arranged baffle. A clamping block two is provided below the baffle. The bottom of the baffle has a threaded hole one, and the clamping block two has a threaded hole two. The threaded hole one and the threaded hole two are coaxial and vertically arranged. The threaded hole two penetrates the clamping block two. A bolt is threadedly connected to both the threaded hole one and the threaded hole two. The head of the bolt is located at the bottom of the clamping block two.

[0014] By adopting the above structural scheme, the height of clamping block two can be changed by tightening the bolts, thereby changing the distance between clamping block one and clamping block two. This makes it easier to adjust the clamping range of the fixture according to electric furnace ingots of different sizes, thus improving the versatility and adaptability of the fixture.

[0015] As a preferred implementation of an electric furnace ingot processing device, the tool holder has through slots on both sides in the width direction of the tool body. The tops of the two through slots penetrate the top of the tool holder, and both through slots are connected to the tool groove. The length of the two through slots is less than the length of the tool body, and the electric furnace ingot facing the tool holder can enter the through slot from top to bottom.

[0016] By adopting the above structural scheme, the groove can prevent interference between the tool holder and the descending electric furnace ingot, so that the tool body does not need to be set on the edge of the tool holder, thus improving the uniformity of the force on the tool holder.

[0017] As a preferred implementation of an electric furnace ingot processing device, two through slots are symmetrically arranged about the cutter slot.

[0018] With the above structural design, the tool groove is located in the middle of the tool holder, that is, the tool body is installed in the middle position of the tool holder, which makes the force on the tool holder more even.

[0019] As a preferred implementation of an electric furnace ingot processing device, the tool holder is connected to a linear transmission mechanism, and the transmission direction of the linear transmission mechanism is set horizontally and perpendicular to the length direction of the tool body.

[0020] The above-mentioned structural design facilitates accurate cutting of risers at different locations, improves the automation level and processing efficiency of the equipment, and can adapt to electric furnace ingots and risers of different sizes.

[0021] As a preferred implementation of an electric furnace ingot processing device, the linear transmission mechanism includes a guide rail, on which a slider is slidably mounted. The slider is connected to an electric push rod, and the length direction of the guide rail and the extension / retraction direction of the electric push rod are both perpendicular to the length direction of the cutter body.

[0022] With the above structural design, the guide rail ensures the linearity and stability of the slider movement, while the electric push rod provides precise power control, making the movement of the tool holder more accurate and reliable.

[0023] The beneficial effects of this utility model include:

[0024] The electric furnace ingot is placed on a disc with the riser aligned with the extrusion orifice. The upper anvil drives the upsetting disc downwards, upsetting the ingot. The riser is extruded from the extrusion orifice, forming the extruded section. Then, a cutting mechanism cuts off the extruded section, discarding smaller sections and preserving larger ones, improving the internal quality of the ingot and increasing the yield rate. This prevents shrinkage defects in the extruded section from moving into the ingot during later drawing processes. The upper surface of the disc in the riser extrusion mechanism is concave towards the center, which helps guide the riser towards the extrusion orifice and facilitates the cutting mechanism in cutting the extruded riser without damaging the surface of the remaining ingot.

[0037] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Reference Figure 1-6 This embodiment proposes an electric furnace ingot processing device, including a riser extrusion mechanism 1 and a cutting mechanism 2. The riser extrusion mechanism 1 includes an upper flat anvil 11, with an upsetting disc 12 connected to the bottom of the upper flat anvil 11. A disc 13 is provided below the upsetting disc 12, and an extrusion hole 14 is opened in the center of the disc 13. The extrusion hole 14 penetrates the disc 13 along the axial direction of the disc 13. The upper surface of the disc 13 is concave inward towards the center, and two oppositely arranged lifting lugs 15 are connected to the outer peripheral surface of the disc 13. Figure 1 and Figure 3 The dashed line in the middle represents a horizontal line.

[0039] The upper anvil 11 is a tool used in the forging process. It is generally rectangular in shape and is driven by the power system of the forging equipment, such as an air hammer, friction press, or hydraulic press, moving downwards at a certain speed and force. When the electric furnace ingot 4 is placed on the disc 13 with the riser aligned with the extrusion hole 14, the upper anvil 11 drives the upsetting disc 12 downwards, upsetting the electric furnace ingot 4. The riser is extruded from the extrusion hole 14, forming the extrusion section 41.

[0040] The chopping mechanism 2 includes a clamp 21 and a chopping knife 22. The clamp 21 has a clamping opening 211 on one side for clamping the electric furnace ingot 4. The top of the clamp 21 is connected to a hydraulic rod 212, which is vertically arranged. The side of the clamp 21 opposite to the clamping opening 211 is connected to a sliding sleeve 213. The sliding sleeve 213 is slidably sleeved on the outside of a sliding rod 214, which is vertically arranged. The chopping knife 22 is located on the side of the clamp 21 with the clamping opening 211. The chopping knife 22 includes a knife holder 221. The top of the knife holder 221 has a knife groove 222, and a knife body 223 is installed in the knife groove 222. When the clamp 21 holds the upsetting electric furnace ingot 4, the side of the electric furnace ingot 4 with the extrusion part 41 extends out from the clamping port 211. The side of the cutter body 223 close to the clamp 21 is flush with the side of the electric furnace ingot 4 with the extrusion part 41. When the hydraulic rod 212 drives the clamp 21 to press down, the root of the connection between the extrusion part 41 and the electric furnace ingot 4 abuts against the top of the cutter body 223. When the hydraulic rod 212 drives the clamp 21 to continue to press down, the cutter body 223 can cut off the extrusion part 41.

[0041] The clamp 21 in this embodiment includes a clamping block 215. The top of the clamping block 215 is connected to the hydraulic rod 212. The bottom of the clamping block 215 is connected to a vertically arranged baffle 216. A clamping block 217 is provided below the baffle 216. The bottom of the baffle 216 has a threaded hole 218, and the clamping block 217 has a threaded hole 219. The threaded hole 218 and the threaded hole 219 are vertical and coaxial. The threaded hole 219 passes through the clamping block 217. A bolt 2110 is threadedly connected to both the threaded hole 218 and the threaded hole 219. The head of the bolt 2110 is located at the bottom of the clamping block 217. Erect the side of the electric furnace ingot 4 with the extrusion part 41 so that the extrusion part 41 extends out of the clamping port 211, and make the side of the electric furnace ingot 4 opposite to the extrusion part 41 abut against the baffle 216. Tighten the bolt 2110, and the second clamping block 217 will move upward, so that the first clamping block 215 and the second clamping block 217 clamp the electric furnace ingot 4. The sliding sleeve 213 and the sliding rod 214 play a guiding role.

[0042] The tool holder 221 has through slots 224 on both sides of the tool body 223 in the width direction. The tops of the two through slots 224 penetrate the top of the tool holder 221, and both through slots 224 are connected to the tool groove 222. The two through slots 224 are symmetrically arranged about the tool groove 222. The length of the two through slots 224 is less than the length of the tool body 223. The electric furnace ingot 4 facing the tool holder 221 can enter the through slot 224 from top to bottom. The length of the tool body 223 is greater than the dimension of the electric furnace ingot 4 in the same direction as the length of the tool body 223. Therefore, the tool body 223 can be positioned in the middle of the tool holder 221, making the force on the tool holder 221 more even.

[0043] The tool holder 221 is connected to the linear transmission mechanism 3, which is horizontally positioned and perpendicular to the length direction of the tool body 223. The linear transmission mechanism 3 includes a guide rail 31, on which a slider 32 slides. The slider 32 is connected to an electric push rod 33. The length direction of the guide rail 31 and the extension / retraction direction of the electric push rod 33 are both perpendicular to the length direction of the tool body 223. This allows adjustment of the position of the tool holder 221, ensuring that the side of the tool body 223 closest to the clamp 21 is more precisely flush with the side of the electric furnace ingot 4 with the extrusion section 41, making it suitable for electric furnace ingots 4 of different sizes.

[0044] Work process:

[0045] The electric furnace ingot 4 is placed on the disc 13, with the riser of the ingot 4 aligned with the extrusion hole 14 at the center of the disc 13. The upper anvil 11 is driven by the power system of the forging equipment, such as an air hammer, friction press, or hydraulic press. The upper anvil 11 moves downward at a certain speed and force, driving the upsetting disc 12 connected to the bottom to move downward, performing an upsetting operation on the electric furnace ingot 4. Because the upper surface of the disc 13 is concave towards the center, it helps guide the riser part to move towards the extrusion hole 14. Finally, the riser is extruded from the extrusion hole 14, forming the extrusion section 41.

[0046] Erect the side of the electric furnace ingot 4 with the extrusion part 41 so that the extrusion part 41 extends out of the clamping opening 211. Align the extrusion part 41 with the blade body 223 and make the side of the electric furnace ingot 4 opposite to the extrusion part 41 abut against the baffle 216. Tighten the bolt 2110 so that the second clamping block 217 moves upward, so that the first clamping block 215 and the second clamping block 217 clamp the electric furnace ingot 4. At the same time, the sliding sleeve 213 slides on the sliding rod 214 to play a guiding role.

[0047] After the electric furnace ingot 4 is clamped and fixed, the cutter holder 221 approaches the extrusion section 41 under the drive of the linear transmission mechanism 3 until the side of the cutter body 223 that is close to the clamp 21 is flush with the side of the electric furnace ingot 4 with the extrusion section 41. Then the hydraulic rod 212 is pressed down, so that the root of the connection between the extrusion section 41 and the electric furnace ingot 4 abuts against the top of the cutter body 223. The hydraulic rod 212 drives the clamp 21 to continue to press down, and the cutter body 223 can gradually cut off the extrusion section 41. The through groove 224 on the cutter holder 221 avoids interference between the cutter holder 221 and the descending electric furnace ingot 4.

[0048] After chopping, the clamp 21 is released and the chopped electric furnace ingot 4 is removed. By discarding the extrusion section 41 containing shrinkage defects, the internal quality of the electric furnace ingot 4 and the yield of the later stage are improved. At the same time, the shrinkage defects in the extrusion section 41 are prevented from moving into the electric furnace ingot 4 during the subsequent drawing process.

[0049] To further improve the yield rate in the later stages, after the electric furnace ingot 4 (with the extrusion section 41 discarded) is drawn and discarded, its two ends are slightly rounded before being transferred to the precision forging machine. This ensures a higher production length of the drawn ingot 4 on the precision forging machine, achieving shrinkage-free forging. This ensures the product's delivery dimensions with minimal material usage, optimizing costs and maximizing profits, allowing customers to obtain better products at lower prices.

[0050] This embodiment can be used to process electric furnace ingots made of materials such as carbon steel, alloy structural steel, hot work die steel, and high-speed steel.
