Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot die casting transfer technology, specifically a transfer device for aluminum ingot die casting. Background Technology

[0002] In the aluminum ingot die casting process, transfer is a key link connecting various production stages. Some aluminum ingots need to undergo pretreatment before die casting, such as removing surface oil and oxide scale or cutting them into small pieces. After pretreatment, they need to be transferred to the feeding area of ​​the smelting furnace. The conveying capacity of the transfer device for aluminum ingots has a certain impact on the processing efficiency.

[0003] For example, patent CN220949842U discloses an aluminum ingot transfer fixture, including an aluminum ingot loading platform with omnidirectional support wheels arranged in a rectangular array at the bottom. Symmetrically arranged rectangular grooves are constructed on the end edges of the loading platform, and side blocking components for assisting loading are rotatably installed between these grooves. Adjustment components for adjusting the angle of the side blocking components are installed between the sidewalls of the side blocking components and the bottom surface of the loading platform. Parallel protective components are installed on the surface of the loading platform. This transfer fixture can assist in lifting aluminum ingots onto a transfer platform and forms a barrier on the edge of the loading platform, providing protection during the transfer and transportation of aluminum ingots. To improve the safety of aluminum ingot transfer, stacking is usually used to transfer aluminum ingots. The overall inertial force of the stacked aluminum ingots increases. When the transfer equipment starts, brakes or turns, the aluminum ingots will be subjected to the inertial force of movement. The top aluminum ingot is prone to tipping over and sliding due to the shift of the center of gravity. Some existing production lines use binding to limit the stacked aluminum ingots, but manual winding and knotting are required, which is time-consuming and labor-intensive. If the limit components around the transfer equipment are set too high, the four directions will be restricted, which is not conducive to the stacking of aluminum ingots on the transfer device with the assistance of hoisting or robotic arms, and is difficult to be used in automated production lines.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing transfer device for aluminum ingot die casting. Utility Model Content

[0005] The purpose of this utility model is to provide a transfer device for aluminum ingot die casting, in order to solve the problem mentioned in the background art that some production lines use a binding method to limit the stacking of aluminum ingots, but this requires manual winding and knotting, which is time-consuming and labor-intensive. Furthermore, if the transfer equipment is equipped with excessively high limiting components around it, the four directions are restricted, which is not conducive to the stacking of aluminum ingots on the transfer device with the assistance of hoisting or robotic arms, making it difficult to apply to automated production lines.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transfer device for aluminum ingot die casting, comprising a transfer frame for transporting aluminum ingot workpieces. Two sets of main rotating shafts are symmetrically mounted on the bottom of the transfer frame about an axis, and a main limiting frame is fixedly mounted on each main rotating shaft. Two sets of auxiliary rotating shafts are also symmetrically mounted on the bottom of the transfer frame about an axis, and auxiliary limiting frames are fixedly mounted on each auxiliary rotating shaft. The auxiliary limiting frames are perpendicular to the main limiting frames, and the height of the main limiting frames is higher than the height of the auxiliary limiting frames. The main and auxiliary limiting frames are provided with reinforcement mechanisms that apply pressure to the top of the aluminum ingot workpieces stacked on the transfer frame.

[0007] Preferably, the reinforcement mechanism includes an electric telescopic rod fixedly installed on the main limiting frame, with the output end of the electric telescopic rod being movably connected to the main limiting frame; the secondary limiting frame has a through hole corresponding to the output end of the electric telescopic rod.

[0008] Preferably, a lifting frame is longitudinally slidably connected to the secondary limiting frame, and a pressure plate is fixedly installed at the bottom of the lifting frame, with the pressure plate positioned below the output end of the electric telescopic rod; a limiting spring is elastically connected between the lifting frame and the secondary limiting frame.

[0009] Preferably, both the main limiting frame and the secondary limiting frame have an embedded groove on the side near the aluminum ingot workpiece, and a clamping component is provided in the embedded groove to apply pressure to the surrounding area of ​​the aluminum ingot workpiece stacked on the transfer vehicle frame.

[0010] Preferably, the clamping assembly includes a pressure rod that is vertically slidably connected to the main limiting frame and the secondary limiting frame. A fixing plate is fixedly sleeved on the outside of the pressure rod, and a positioning spring is elastically connected between the fixing plate and the main limiting frame and the secondary limiting frame. The pressure rod is naturally fitted into the inner groove.

[0011] Preferably, a column is fixedly installed on the upper end face of the pressure rod, and a main pull rope is fixedly connected to the column in the main limiting frame. The other end of the main pull rope is fixedly connected to the output end of the electric telescopic rod.

[0012] Preferably, an auxiliary pull rope is fixedly connected to the column in the auxiliary limiting frame, and the other end of the auxiliary pull rope is fixedly connected to the pressure plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the main limiting frame and the secondary limiting frame of the aluminum ingot die casting transfer device can be rotated and unfolded, or rotated and combined to cover the outside of the stacked aluminum ingots. The operation is quick and convenient, and it can be reused multiple times. Moreover, the main limiting frame and the secondary limiting frame after being rotated and unfolded can maintain sufficient loading and unloading space above the transfer vehicle frame, which is convenient to cooperate with mechanical hoisting equipment or robot to control the loading and unloading of aluminum ingots. It is suitable for automated production lines.

[0014] The main limit frame and the secondary limit frame are equipped with a reinforcement mechanism that applies pressure to the top of the stacked aluminum ingot workpieces on the transfer frame. After the limit frame and the secondary limit frame are controlled to rotate and the cover is set outside the stacked aluminum ingot, the electric telescopic rod is operated so that its output end passes through the through hole. The output end of the electric telescopic rod contacts the pressure plate and pushes the pressure plate to press tightly on the top of the stacked aluminum ingot, keeping the aluminum ingot stably stacked on the transfer frame.

[0015] The embedded groove is equipped with a clamping component that applies pressure to the four sides of the stacked aluminum ingots on the transfer frame. When the output end of the electric telescopic rod pushes the pressure plate down to clamp the aluminum ingot, the output end of the electric telescopic rod and the pressure plate respectively drive the main pull rope and the auxiliary pull rope to stretch and tighten. The main pull rope and the auxiliary pull rope drive the pressure rods in multiple directions to press the stacked aluminum ingots around, forming a "mechanical binding" state, which further stabilizes and limits the aluminum ingots on the transfer frame.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-4 This utility model provides the following technical solution: a transfer device for aluminum ingot die casting, including a transfer frame 1 for transporting aluminum ingot workpieces. The bottom of the transfer frame 1 is provided with brakeable rollers. Two sets of main rotating shafts 2 are symmetrically mounted on the bottom of the transfer frame 1 about an axis. A main limiting frame 3 is fixedly mounted on the main rotating shaft 2. Two sets of auxiliary rotating shafts 4 are also symmetrically mounted on the bottom of the transfer frame 1 about an axis. The installation position of the auxiliary rotating shafts 4 on the transfer frame 1 is higher than that of the main rotating shafts 2 on the transfer frame 1, and their rotation does not interfere with each other. A secondary limiting frame 5 is fixedly mounted on the secondary rotating shaft 4. The secondary limiting frame 5 is perpendicular to the main limiting frame 3, and the height of the main limiting frame 3 is higher than that of the secondary limiting frame 5. Both the main limiting frame 3 and the secondary limiting frame 5 are U-shaped structures and have the same thickness, which can simultaneously limit the four sides and the top of the aluminum ingot. The main limiting frame 3 and the secondary limiting frame 5 are provided with a reinforcing mechanism to apply pressure to the top of the aluminum ingot workpieces stacked on the transfer frame 1.

[0027] Please see Figures 2-7 The reinforcement mechanism includes an electric telescopic rod 6 fixedly installed on the main limiting frame 3. The output end of the electric telescopic rod 6 is movably connected to the main limiting frame 3. Two electric telescopic rods 6 are symmetrically arranged on the main limiting frame 3 along the axial direction. The secondary limiting frame 5 has a through hole 7 corresponding to the output end of the electric telescopic rod 6. The output end of the electric telescopic rod 6 moves outward and can pass through the through hole 7. A lifting frame 8 is longitudinally slidably connected to the secondary limiting frame 5. A pressure plate 9 is fixedly installed at the bottom of the lifting frame 8 and is located below the output end of the electric telescopic rod 6. A limit spring 10 is elastically connected between the lifting frame 8 and the secondary limiting frame 5. Under natural pressure, the pressure plate 9 adheres to the secondary limiting frame 5 under the elastic tension of the limit spring 10, maintaining the distance between it and the stacked aluminum ingots, which facilitates the control of the rotation and adjustment of the secondary limiting frame 5 on the transfer vehicle frame 1.

[0028] After the aluminum ingots are pre-processed, they need to be stacked on the transfer frame 1 and transported to other processing equipment. The main limit frame 3 and the secondary limit frame 5 are controlled to rotate and unfold next to the transfer frame 1. The transfer frame 1 is in a relatively open state around its sides and top, which makes it convenient for hoisting machinery or robotic arms to move and stack the aluminum ingots on the transfer frame 1. The aluminum ingots are stacked layer by layer in a crisscross pattern to increase the friction between the upper and lower layers of aluminum ingots and prevent them from sliding easily relative to each other.

[0029] After stacking, first control the rotation of the secondary limiting frame 5 to cover the outside of the aluminum ingot, then control the rotation of the main limiting frame 3 to cover the outside of the aluminum ingot. The main limiting frame 3 is simultaneously covered outside the secondary limiting frame 5. The electric telescopic rod 6 is operated, and the output end of the electric telescopic rod 6 moves outward and approaches the secondary limiting frame 5. The output end of the electric telescopic rod 6 passes through the through hole 7 on the secondary limiting frame 5. With the combination of the output end of the electric telescopic rod 6 and the through hole 7, the rotation position of the main limiting frame 3 and the secondary limiting frame 5 can be quickly limited, so that the two together protect the aluminum ingot around the sides and top.

[0030] Continue to control the output end of the electric telescopic rod 6 to move outward, and its output end contacts and squeezes the pressure plate 9 below, pushing the pressure plate 9 to move downward. The pressure plate 9 moves down and presses against the stacked aluminum ingots, pressing and limiting the top of the stacked aluminum ingots, keeping the aluminum ingots stably stacked on the transfer frame 1, and preventing them from losing balance and tipping over during the transfer process due to inertia, thus maintaining the stability of the aluminum ingots during the transfer process.

[0031] Example 2: Please refer to Figures 4-6 Based on Embodiment 1, a clamping assembly 12 is also disclosed, the specific structure of which is as follows: an embedded groove 11 is provided on the side of the main limiting frame 3 and the secondary limiting frame 5 near the aluminum ingot workpiece, and a clamping assembly 12 is provided in the embedded groove 11 to apply pressure to the surrounding direction of the aluminum ingot workpiece stacked on the transfer frame 1.

[0032] Please see Figure 7 and Figure 8 The clamping assembly 12 includes a pressure rod 121 vertically slidably connected to the main limiting frame 3 and the secondary limiting frame 5. A fixing plate 122 is fixedly sleeved on the outside of the pressure rod 121. A positioning spring 123 is elastically connected between the fixing plate 122 and the main limiting frame 3 and the secondary limiting frame 5. In its natural state, the pressure rod 121 is fitted into the inner groove 11. A column 124 is fixedly installed on the upper end face of the pressure rod 121. A main pull rope 125 is fixedly connected to the column 124 in the main limiting frame 3. The other end of the main pull rope 125 is fixedly connected to the output end of the electric telescopic rod 6. A secondary pull rope 126 is fixedly connected to the column 124 in the secondary limiting frame 5. The other end of the secondary pull rope 126 is fixedly connected to the pressure plate 9.

[0033] During the process of the electric telescopic rod 6 pushing the pressure plate 9 downward, the electric telescopic rod 6 drives the main pull rope 125 to move synchronously through the through hole 7. The main pull rope 125 tightens under the tension, driving the pressure rod 121 on the main limit frame 3 to move closer to the stacked aluminum ingots. The pressure rod 121 drives the fixed plate 122 to move synchronously. The fixed plate 122 compresses the positioning spring 123 to adjust the moving position of the pressure rod 121. The pressure rod 121 on the main limit frame 3 presses against the left and right sides of the aluminum ingot, maintaining the stability of the aluminum ingot in this direction during transportation.

[0034] As the pressure plate 9 moves downward, it causes the auxiliary pull rope 126 to move and stretch. The tension of the auxiliary pull rope 126 causes the pressure rod 121 on the auxiliary limit frame 5 to move closer to the aluminum ingot. This causes the pressure rod 121 on the auxiliary limit frame 5 to move and press against the front and rear sides of the aluminum ingot, maintaining the stability of the aluminum ingot in this direction during transportation. The pressure rods 121 on the main limit frame 3 and the auxiliary limit frame 5 press and limit the aluminum ingot around its perimeter, fully maintaining the stability of the aluminum ingot stack on the transport frame 1 and preventing the aluminum ingot from losing balance due to inertia during transportation.

[0035] The main limiting frame 3 and the secondary limiting frame 5 are vertically positioned to protect the outside of the aluminum ingot, forming a "mechanical binding" protection that eliminates the need for manual binding and allows for repeated use, making operation very convenient.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
