Description

Technical Field

[0001] This utility model relates to a scrap steel processing device, belonging to the technical field of mechanical devices in the metallurgical industry. Background Technology

[0002] Rock drill manufacturers typically lack steelmaking equipment, relying primarily on purchasing raw steel ingots. However, during the production of rock drills such as the 7655 and B87C models, the machining of forged cylinders generates a large amount of blanking rods and iron filings. Due to product shape characteristics, process limitations, and equipment constraints, these blanking rods and iron filings can only be sold at low prices as scrap steel, resulting in low material utilization. Therefore, it is essential to develop a scrap steel processing device capable of melting the blanking rods and iron filings generated during cylinder production into steel ingots for use as raw material, thereby saving on steel ingot procurement costs and shortening the production cycle. Utility Model Content

[0003] The purpose of this invention is to provide a scrap steel processing device that can melt the billets and iron filings generated during cylinder production into steel ingots for use as forging raw materials, thereby solving the problems existing in the background art.

[0004] The technical solution of this utility model is:

[0005] A scrap steel processing device includes guide columns, anvils, fixed crossbeams, movable upper crossbeams, movable lower crossbeams, clamping hydraulic cylinders, a furnace, a base, ceramic bending plates, graphite electrodes, ceramic sleeves, and lifting hydraulic cylinders. The furnace and base are fixedly connected as a single unit. The anvil is a single unit consisting of a pressure rod and a pressure plate, the size of which matches the size of the furnace. Several guide columns are mounted on the base, with fixed crossbeams, movable upper crossbeams, and movable lower crossbeams positioned between them. The movable upper and lower crossbeams are slidably connected to the guide columns. Two clamping hydraulic cylinders, cooperating with the pressure rods, are positioned between the movable upper and lower crossbeams. The lifting hydraulic cylinders are driven by the movable lower crossbeams. Several graphite electrodes are fixed to the bottom of the furnace via ceramic bending plates, and each graphite electrode is covered with a ceramic sleeve.

[0006] The cylinder bodies of the two clamping hydraulic cylinders are respectively fixed between the movable upper crossbeam and the movable lower crossbeam. The cylinder rods of the two clamping hydraulic cylinders are respectively connected to a clamping block, and the two clamping blocks cooperate with the pressure rod.

[0007] The surfaces of the two clamping blocks that contact the pressure rod are arc-shaped.

[0008] The ceramic bending plate is fixed to the bottom of the furnace by bolts, and a spring is provided between each graphite electrode and the ceramic bending plate.

[0009] The fixed crossbeam is located above the movable upper crossbeam and the movable lower crossbeam.

[0010] The inside of the furnace and under the pressure plate are both lined with high-temperature resistant materials.

[0011] Using this invention, the feed bar and iron filings are poured into the furnace. The graphite electrode is then connected to a high-voltage circuit. When the scrap steel comes into contact with the positive and negative electrodes of the graphite electrode, a current sufficient to melt the scrap steel is generated locally, causing the scrap steel temperature to rise rapidly. Once the melting point of steel is reached, the scrap steel begins to melt into molten steel. The movable upper and lower crossbeams, under the control of the lifting hydraulic cylinder, slowly move the anvil downwards to assist in the melting and heat preservation of the scrap steel, thereby improving the melting efficiency. When the scrap steel in the furnace has completely melted and formed a steel ingot, the graphite electrode is de-energized, the lifting hydraulic cylinder lifts the anvil, and after the steel ingot cools, it is lifted out by a suction cup.

[0012] The beneficial effects of this utility model are:

[0013] (1) It can melt the scrap rods and iron filings generated during the production of products such as rock drill cylinders into steel ingots, improve the utilization rate of scrap steel, save steel ingot procurement costs, and shorten the production cycle.

[0014] (2) Since the chemical composition of the billet and iron filings is completely consistent with that of the raw steel ingot, the process of this device is simpler and the cost is lower than that of steelmaking equipment such as converters and electric furnaces when producing steel ingots. The maintenance cost is also low. Attached Figure Description

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

[0025] See attached document Figure 1-8 A scrap steel processing device includes guide columns 1, anvils 2, fixed crossbeams 3, movable upper crossbeams 4, movable lower crossbeams 5, clamping hydraulic cylinders 7, a furnace 8, a base 9, ceramic bending plates 11, graphite electrodes 13, ceramic sleeves 14, and lifting hydraulic cylinders 16. The furnace 8 and the base 9 are fixedly connected as a single structure. The anvil 2 is a single structure composed of a pressure rod 21 and a pressure plate 22, the size of which matches the size of the furnace 8. The base 9 is provided with several guide columns 1, and between the guide columns 1 are fixed crossbeams 3, movable upper crossbeams 4, and movable lower crossbeams 5. The movable upper crossbeams 4 and movable lower crossbeams 5 are slidably connected to the guide columns 1. Between the movable upper crossbeams 4 and movable lower crossbeams 5 are two clamping hydraulic cylinders 7 that cooperate with the pressure rods 21. The lifting hydraulic cylinders 16 are drivenly connected to the movable lower crossbeams 5. Several graphite electrodes 13 are fixed to the bottom of the furnace 8 by ceramic bending plates 11, and each graphite electrode 13 is provided with a ceramic sleeve 14.

[0026] In this embodiment, refer to the appendix Figure 1-8 There are four guide columns 1, the base 9 is rectangular, the furnace 8 and the base 9 are integrated into one structure, and the inner surface of the furnace 8 is inlaid with high temperature resistant material 10. The size of the inner cavity formed by the high temperature resistant material 10 depends on the steel plate specifications required for the stamping product.

[0027] The fixed crossbeam 3 is fixed on the four guide columns 1, and the fixed crossbeam 3 is located above the movable upper crossbeam 4 and the movable lower crossbeam 5.

[0028] The cylinder bodies of the two clamping hydraulic cylinders 7 are fixed between the movable upper crossbeam 4 and the movable lower crossbeam 5, respectively. The cylinder rods of the two clamping hydraulic cylinders 7 are connected to a clamping block 6 through a pin, and the two clamping blocks 6 can clamp the pressure rod 21.

[0029] The anvil 2 is an integral structure consisting of a pressure rod 21 and a pressure plate 22. The size of the pressure plate 22 is matched with the size of the furnace 8. A high-temperature resistant material 10 is provided under the pressure plate 22.

[0030] The ceramic bent plate 11 has mounting holes that correspond to the threaded holes on the base 9. Bolts 15 pass through the mounting holes on the ceramic bent plate 11 to connect the ceramic bent plate 11 to the base 9. The ceramic sleeve 14 is interference-fitted with the high-temperature resistant material 10 inside the furnace 8. The graphite electrode 13 is guided through the ceramic sleeve 14 and is clearance-fitted with the ceramic sleeve 14. One side of the spring 12 is mounted on the ceramic bent plate 11, and the other side is connected to the graphite electrode 13, serving to support the graphite electrode 13.

[0031] First, extend the lifting hydraulic cylinder 16 to its maximum position, raising components such as the movable upper crossbeam 4 and movable lower crossbeam 5 to their highest points. Then, the piston rods of the two clamping hydraulic cylinders 7 extend, clamping the pressure rod 21 of the anvil 2 via the two clamping blocks 6. Next, pour the same type of steel bar and iron filings into the furnace 8. Then, use the lifting hydraulic cylinder 16 to press the pressure plate 22 of the anvil 2 onto the scrap steel in the furnace 8. The graphite electrode 13 is then connected to high voltage. Once the scrap steel contacts the positive and negative electrodes of the graphite electrode... A localized current sufficient to melt the scrap steel is generated, causing the scrap steel temperature to rise rapidly. Once the steel's melting point is reached, the scrap steel begins to melt into molten steel. Under the control of the lifting hydraulic cylinder 16, the movable upper beam 4 and movable lower beam 5 slowly move the anvil 2 downwards to assist in the melting and heat preservation of the scrap steel, thereby improving melting efficiency. When the scrap steel in the furnace has completely melted and formed a steel ingot, the graphite electrode is de-energized, and the lifting hydraulic cylinder 16 lifts the anvil 2. After the steel ingot cools, it is lifted out by a suction cup.
