Description

Technical Field

[0001] This invention relates to the field of aluminum processing technology, specifically to an automatic conveying and sorting device for heavy-duty hydraulic shear heads, which is particularly suitable for the automatic conveying and sorting of material heads cut by heavy-duty hydraulic shears according to alloy grades during the hot rolling production of aluminum ingots. Background Technology

[0002] The production of aluminum alloy sheets and strips typically uses aluminum ingots (aluminum plates or flat ingots) as raw materials. During the casting process, aluminum ingots often exhibit casting defects on their surface and at both ends, such as porosity, segregation, oxide scale, cracks, chilled hardening layers, and gate burrs. After high-temperature rolling, these defects can extend into the interior of the sheet or strip, causing quality problems such as peeling, delamination, and even breakage in the finished product.

[0003] In the reciprocating multi-pass reversible hot rolling process of aluminum ingots, a "crocodile mouth" (open-mouth delamination and cracking) phenomenon gradually forms and worsens at the ingot's head and tail, which is the most typical inherent defect in the rough rolling process. To address this, heavy-duty hydraulic shears are typically installed on the production line to cut off and remove the waste sections at the head and tail of the rolled ingot, thereby reducing the defect rate in subsequent rolling processes. However, the existing methods for collecting, transferring, and sorting the waste sections cut off by heavy-duty hydraulic shears present the following problems: 1. Traditional material bins are bulky and require overhead cranes for transport. Tilting the material bins is also difficult and inconvenient.

[0004] 2. After the material heads are poured out of the hopper, they need to be manually sorted and stacked according to the alloy grade, and then transported to the designated storage area by forklift. The whole process involves multiple manual steps and is inefficient.

[0005] 3. The material box needs to be hoisted every 15-20 minutes, which occupies the overhead crane resources for a long time during the production process and seriously affects other operations of the overhead crane.

[0006] 4. To complete the waste disposal work, it is necessary to have a fixed number of crane operators, stackers and forklift operators, which results in high labor costs. In addition, manual sorting is prone to mixing of aluminum ingots of different series.

[0007] 5. Aluminum scrap is mostly made of metal materials, and the edges and corners are sharp after being cut and shaped. There is a significant safety hazard for workers who directly handle it.

[0008] Therefore, the aluminum processing industry urgently needs a device that can automatically convey material heads and automatically sort them according to alloy grades to solve the above problems. Summary of the Invention

[0009] In view of the technical problems of existing technologies, such as reliance on manual labor, low efficiency, occupation of overhead crane resources, and safety hazards in the handling of heavy-duty hydraulic shear heads, this invention provides an automatic conveying and sorting device for heavy-duty hydraulic shear heads, which aims to realize the automated collection, conveying and sorting of material heads according to alloy grade, reduce manual intervention and improve production efficiency.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: An automatic conveying and sorting device for heavy-duty hydraulic shear heads is installed on a rolling production line. A chute is set up near the heavy-duty hydraulic shear on the rolling production line, and a trench is set up on the side of the rolling production line. A movable transfer trolley is set up in the trench, and multiple distribution boxes are set up on the ground. The transfer trolley has a transfer box, a lifting mechanism and a tilting mechanism, which are used to receive the head falling into the chute, and then lift the head and pour it into the distribution box.

[0011] Further improvement of the technical solution: A pushing mechanism is set on the heavy-duty hydraulic shear, which is used to push the material head cut off by the heavy-duty hydraulic shear into the chute.

[0012] Further improvement to the technical solution: The pushing mechanism consists of a pushing cylinder and multiple connecting rods.

[0013] Further improve the technical solution: a guide rail is installed in the trench, and the transfer trolley is driven by a motor and can move on the guide rail.

[0014] Further improvement of the technical solution: The transfer box is hinged to the top of the lifting mechanism, and the flipping mechanism is a flipping cylinder that drives the transfer box to flip to the side of the distribution box.

[0015] Further improve the technical solution: The lifting mechanism consists of a lifting cylinder and a folding frame, and the lifting cylinder is used to drive the folding frame to lift.

[0016] Further improvements to the technical solution include a control system that, based on the material of the material head, controls the transfer trolley to pour the material head into the designated distribution box.

[0017] Further improvement of the technical solution: The control system is connected to the MES system of the rolling production line to obtain the grade information of the currently rolled ingot.

[0018] After implementing the above technical solution, compared with the prior art, the present invention can produce the following beneficial effects: 1. Reasonable layout and high space utilization: The present invention sets the chute on the side of the production line, sets the transfer trolley in the trench, and sets the material distribution box above the ground, making full use of the three-dimensional space on the side of the production line, without affecting the process flow of the rolling production line, and has little impact on the existing production line when it is modified.

[0019] 2. High degree of automation: By receiving the material head through chutes, automatically moving and tilting the transfer trolley, and automatically sorting according to alloy grade by the control system, the entire process from material head collection to sorting is automated. There is no need for manual direct contact with high temperature and sharp material head, thus eliminating safety hazards.

[0020] 3. Free up overhead crane resources: The transfer trolley moves on its own in the trench, eliminating the need for overhead crane hoisting, which completely solves the problem of material boxes occupying the overhead crane for a long time in the traditional solution, allowing the overhead crane to focus on other production operations.

[0021] 4. Reduced labor costs: There is no need to permanently employ crane operators, stackers, and forklift operators. Only a small number of personnel are needed to monitor the operation of the equipment, which greatly reduces labor costs.

[0022] 5. Avoid mixing materials and increase the value of scrap: The control system automatically classifies and stores materials according to alloy grade, avoiding the mixing problems that are easy to occur during manual sorting, ensuring the purity of aluminum alloy scrap of different grades, which is conducive to the recycling of scrap and increases the economic value of scrap.

[0023] 6. Stable and reliable operation: The guide rail guides the trolley to move, the lifting mechanism adopts a mature folding frame structure, and the tilting mechanism is driven by a hydraulic cylinder. The operation of each mechanism is reliable and suitable for long-term stable operation in harsh rolling workshop environments such as high temperature and dust. Attached Figure Description

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0032] Reference Figure 1-6 The automatic material conveying and sorting device of the present invention is installed on the aluminum alloy rolling production line 1, and mainly consists of a heavy-duty hydraulic shear 2, a transfer trolley 5 and multiple material distribution boxes 6.

[0033] A heavy-duty hydraulic shear 2 is installed on the rolling production line 1, and a chute 3 is installed on the rolling production line 1 near the heavy-duty hydraulic shear 2. Multiple material distribution boxes 6 are installed on the ground, and each material distribution box 6 is used to hold the stubs of different aluminum alloy grades.

[0034] To ensure that the material head can smoothly enter the chute, a pushing mechanism 7 is installed on the heavy-duty hydraulic shear 2. The pushing mechanism 7 consists of a pushing cylinder and three connecting rods. When the pushing cylinder extends, the material head 9 can be pushed into the chute 3 through the movement of the connecting rods.

[0035] A trench is provided on the side of the rolling production line 1, perpendicular to the rolling production line 1. A guide rail 4 and a transfer trolley 5 are installed within the trench. The wheels of the transfer trolley 5 are driven by a motor and can move on the guide rail 4. The transfer trolley 5 has a transfer box 5.1, a lifting mechanism 5.2, and a tilting mechanism 5.3. The transfer trolley 5 is used to receive the material head 9 falling into the chute 3, then lifts the material head 9 and pours it into the designated distribution box 6.

[0036] Specifically, the transfer box 5.1 is hinged to the top of the lifting mechanism 5.2, and the tilting mechanism 5.3 is a tilting cylinder that drives the transfer box 5.1 to tilt towards the distribution box 6. The lifting mechanism 5.2 consists of a lifting cylinder and multiple sets of X-shaped folding frames, with the lifting cylinder driving the folding frames to rise and fall. During operation, the lifting mechanism 5.2 causes the transfer box 5.1 to rise and fall, and the tilting mechanism 5.3 causes the transfer box 5.1 to tilt.

[0037] To achieve automated conveying and sorting, this invention also includes a control system connected to the MES system of the rolling production line 1. This control system acquires the grade information of the currently rolled ingot and then controls the transfer trolley 5 to move the ingot head 9 into the designated distribution box 6. When an aluminum ingot 8 of a certain alloy grade enters the rolling production line 1, the MES system sends the alloy grade information of that ingot 8 to the control system. Based on this information, the control system determines the position of the distribution box 6 corresponding to that alloy grade and plans the travel path of the transfer trolley 5.

[0038] Work process: In the first step, aluminum ingot 8 is placed on the rolling production line 1. During the reciprocating multi-pass reversible hot rolling process, "alligator mouth" defects will form at the head and tail ends of aluminum ingot 8. When aluminum ingot 8 moves to the heavy-duty hydraulic shear 2, the heavy-duty hydraulic shear 2 cuts off the waste sections at the head and tail of aluminum ingot 8, forming the material head 9.

[0039] The second step involves the sheared material from the top of the aluminum ingot falling into chute 3 under its own weight, and then sliding down chute 3 into the transfer box 5.1 of the transfer trolley 5. Figure 1 As shown. The material head 9 cut off at the tail end of the aluminum ingot has a certain distance from the chute 3. It needs to be pushed into the chute 3 by the pushing mechanism 7, such as... Figure 6 As shown.

[0040] Thirdly, when the material head 9 in the transfer box 5.1 accumulates to a certain amount, the control system controls the transfer trolley 5 to move along the guide rail 4 to below the material distribution box 6 corresponding to the currently rolled alloy grade, such as... Figure 4 As shown.

[0041] Fourthly, the lifting cylinder drives the folding frame to unfold upwards, raising the transfer box 5.1 to a high position. Then, the tilting cylinder extends, driving the transfer box 5.1 to tilt towards the distribution box 6, emptying all the material heads 9 inside the transfer box 5.1 into the distribution box 6. Figure 5 As shown.

[0042] Fifth step, the tilting cylinder retracts, and the transfer box 5.1 returns to its original position; the lifting cylinder retracts, the folding frame closes, and the transfer box 5.1 descends to its low position; the transfer trolley 5 returns along the guide rail 4 to below the discharge end of the chute 3 to continue receiving the next batch of material.

[0043] This invention enables automated shearing, conveying, and sorting of aluminum ingot heads. Compared to traditional methods, this invention saves 2-3 workers, completely frees up overhead crane resources, avoids material mixing problems, and significantly improves the recycling value of waste materials, resulting in significant economic and social benefits.

[0044] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this invention should be included within the scope of protection of this invention.
