Description

Technical Field

[0001] This utility model relates to an automatic aluminum liquid transfer and supply device, used in a low-pressure casting production system to transfer aluminum liquid to a holding furnace, and belongs to the technical field of casting machines. Background Technology

[0002] The aluminum liquid transfer system is a device used in the casting production line to transfer aluminum liquid holding furnaces. After the aluminum liquid is melted and prepared in the melting furnace, it is automatically discharged into the prepared transfer holding furnace. The transfer holding furnace is placed on the aluminum liquid transfer trolley. After the aluminum liquid is added, the holding furnace is transported to the heating station by the aluminum liquid transfer trolley.

[0003] Traditional aluminum liquid transfer systems can only perform furnace changing operations by manually operating trolleys. Each trolley can only complete the interactive operation of one grade of aluminum liquid holding furnace. This operation method cannot meet the factory's simultaneous production needs of multiple aluminum liquid grades, and it cannot automatically transfer and replace holding furnaces between heating stations, transfer trolleys, and casting machines, resulting in low production efficiency of the casting line.

[0004] Therefore, this utility model is proposed. Utility Model Content

[0005] To address the aforementioned technical problems in the prior art, the purpose of this utility model is to provide a large-capacity automatic aluminum liquid transfer and supply device. The transfer trolley is equipped with two holding furnace placement stations and has a push-pull mechanism, which can automatically transfer and replace the holding furnaces between the heating station, the transfer trolley, and the casting machine, thereby improving the production efficiency of the casting line.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] An automatic transfer and supply device for large-capacity molten aluminum includes a transfer trolley with a drive mechanism. The drive mechanism drives the transfer trolley to reciprocate on two parallel tracks. The transfer trolley has two workstations, each equipped with a holding furnace slide rail and a push-pull mechanism. The push-pull mechanism moves the holding furnace on the holding furnace slide rail. The drive mechanism includes a drive motor connected to a drive shaft. The two ends of the drive shaft are respectively equipped with an active positioning slot wheel mechanism and an active smooth wheel mechanism. The push-pull mechanism includes a lead screw mounted on the transfer trolley. The lead screw is driven by a lead screw motor and has a base. The base has a push rod, and the end of the push rod has a holding furnace connector connected to a hook on the holding furnace.

[0008] The active positioning slot wheel mechanism includes a mounting base, in which a positioning slot wheel is provided. The drive shaft passes through the mounting base, and the positioning slot wheel is connected to the end of the drive shaft and rotates under the drive of the drive shaft.

[0009] The positioning groove wheel includes a body, and cams are provided on both sides of the body. A groove is formed between the cams and the body, and the track is located in the groove.

[0010] The end of the push rod is connected to the base body by a pin. The push rod rotates relative to the base body with the pin as the fulcrum, and a handle is provided on the push rod.

[0011] A positioning mechanism is provided between the two workstations of the transfer trolley. The positioning mechanism includes a slide rail and a locking position on the transfer trolley. A positioning body is slidably connected to the slide rail. A positioning motor is connected to the positioning body. The output shaft of the positioning motor passes through the positioning body and is connected to the transfer trolley. The output shaft is a telescopic shaft. The positioning body slides along the slide rail under the drive of the positioning motor and finally falls into the locking position to achieve positioning.

[0012] The positioning body has sliding bars on both sides, and the sliding bars slide along the slide rail.

[0013] The positioning mechanism is provided with driven wheel assemblies on both sides, and the driven wheel assemblies include a driven optical wheel mechanism and a driven positioning slot wheel mechanism.

[0014] The transfer trolley is equipped with scrapers at all four corners.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model's large-capacity automatic aluminum liquid transfer and supply device can place the transfer and holding furnace on a transfer trolley. After the aluminum liquid is added, the transfer trolley transports the holding furnace to the heating station. The transfer trolley is equipped with two holding furnace placement stations, which can meet the transfer and handling operations of a 3T aluminum liquid holding furnace.

[0017] This utility model also includes two sets of drive devices to prevent the grooved wheel or smooth wheel on one side from being suspended due to uneven track, which would prevent the transfer trolley from running. The grooved wheel cooperates with the track to enable the transfer trolley to run on the designated route. Through precise positioning of the groove, the transfer trolley runs accurately and smoothly. The positioning mechanism cooperates with the pin hole on the top surface to ensure that the transfer trolley does not shift or shake when the heat preservation furnace is pushed or pulled on it. The scraper can scrape off the garbage on the rail during the movement of the transfer trolley to prevent debris from entering the grooved wheel and causing the trolley to jam.

[0018] The transfer trolley in this invention is equipped with a push-pull mechanism, which can automatically transfer and replace the heat preservation furnace between the heating station, the transfer trolley, and the casting machine, thereby improving the production efficiency of the casting line.

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0028] like Figure 1-7As shown, the large-capacity automatic aluminum liquid transfer and supply device of this utility model includes a transfer trolley 1. The transfer trolley 1 is equipped with a drive mechanism 6, which drives the transfer trolley 1 to reciprocate on two parallel tracks 2. The drive mechanism 6 is located on the side of the push-pull mechanism 5. The layout of the drive mechanism 6 on the overall transfer trolley 1 ensures that the two drive mechanisms 6 are located at both ends of the transfer trolley 1, preventing the positioning groove wheel or the smooth wheel on one side from being suspended due to the track 2 not being level, thus preventing the transfer trolley 1 from running. The drive mechanism 6 includes a drive motor 61, which is a geared motor. The drive motor 61 is connected to a drive shaft 62. The two ends of the drive shaft 62 are respectively equipped with an active positioning groove wheel mechanism 63 and an active smooth wheel mechanism 64. The active positioning groove wheel mechanism 63 includes a mounting base 631, in which a positioning groove wheel is provided. The drive shaft 62 passes through the mounting base 631, and the positioning groove wheel is connected to the end of the drive shaft 62 and rotates under the drive of the drive shaft 62. The positioning slot wheel includes a body 632, with cams 633 on both sides of the body 632. A slot is formed between the cams 633 and the body 632, and the track 2 is located in the slot. Through the cooperation of the slot and the track 2, the transfer trolley 1 can run on a designated route. The precise positioning through the slot ensures that the transfer trolley 1 runs accurately, smoothly, and without slippage. In the active optical wheel mechanism 64, the rolling wheel does not have a slot, but the other structures are the same as the active positioning slot wheel mechanism 63.

[0029] The transfer trolley 1 is equipped with a mechanical anti-collision strip 11 and a safety scanner 10 on its side, and a laser rangefinder 13 is installed on the transfer trolley 1 to detect the position of the transfer trolley 1 in real time, ensuring that the transfer trolley 1 can accurately position itself to work at each workstation. The safety scanner 10 prevents the transfer trolley 1 from colliding with obstacles during operation, and together with the mechanical anti-collision strip 11, ensures the safe operation of the transfer trolley. The control process of the transfer trolley 1 is controlled by the control panel 12, and the power is distributed through the tubular sliding contact line. The voltage is stepped down by the transformer 9 to a safe voltage of 36V to ensure safe operation.

[0030] The transfer trolley in this invention features two workstations arranged in a frame configuration, capable of handling and transferring 3T aluminum liquid holding furnaces. The two workstations are identically arranged, each equipped with two holding furnace slide rails 4 and one push-pull mechanism 5, allowing simultaneous pushing and pulling of two holding furnaces with a capacity of 3000kg aluminum. The two holding furnace slide rails 4 are arranged parallel to each other, with the spacing between them adapted to the size of the holding furnace. The push-pull mechanism 5 is located between the two holding furnace slide rails 4, driving the holding furnace to move along the slide rails, ensuring stable and vibration-free switching operation of the holding furnaces.

[0031] Furthermore, the push-pull mechanism 5 of this utility model includes a lead screw 51 mounted on the transfer trolley 1. The lead screw 51 is driven by a lead screw motor (mounted on the back of the transfer trolley 1, not shown in the attached drawings). A seat 52 is provided on the lead screw 51, and a push rod 53 is provided on the seat 52. A heat preservation furnace connector 54 is provided at the end of the push rod 53. The heat preservation furnace connector 54 is connected to a hook on the heat preservation furnace (mounted on the side wall of the heat preservation furnace, not shown in the attached drawings). The end of the push rod 53 is connected to the seat 52 via a pin 56. The push rod 53 rotates relative to the seat 52 with the pin 56 as a fulcrum, and a handle 55 is provided on the push rod 53. The heat preservation furnace connector 54 is connected to the hook on the heat preservation furnace via the handle 55, thus pushing the heat preservation furnace upwards and outwards from the transfer trolley.

[0032] Furthermore, a positioning mechanism 3 is provided between the two workstations of this utility model. The positioning mechanism 3 includes a slide rail 31 and a locking position 32 mounted on the transfer trolley 1. A positioning body 33 is slidably connected to the slide rail 31, and sliding strips 36 are provided on both sides of the positioning body 33. The sliding strips 36 slide along the slide rail 31. A positioning motor 34 is connected to the positioning body 33. The output shaft 35 of the positioning motor 34 passes through the positioning body 33 and is connected to the transfer trolley 1. The output shaft 35 is a telescopic shaft. Driven by the positioning motor 34, the positioning body 33 slides along the slide rail 31 and finally falls into the locking position 32 to achieve positioning. This positioning mechanism 3 cooperates with the positioning holes on the equipment base, so that when the heat preservation furnace is pushed and pulled on the transfer trolley 1, it can automatically find the workstation and position itself, avoiding the problem of the transfer trolley 1 shaking without displacement.

[0033] Furthermore, to improve the stability of the transfer trolley 1 on the track 2, the positioning mechanism 3 in this invention is provided with driven wheel assemblies on both sides. The driven wheel assembly includes a driven optical wheel mechanism 7 and a driven positioning slot wheel mechanism 8. The structure of the driven optical wheel mechanism 7 is the same as that of the active optical wheel mechanism 64, and the structure of the driven positioning slot wheel mechanism 8 is the same as that of the active positioning slot wheel mechanism 63. When the active optical wheel mechanism 64 and the active positioning slot wheel mechanism 63 rotate, they drive the driven optical wheel mechanism 7 and the driven positioning slot wheel mechanism 8 to rotate, providing better power to the transfer trolley 1.

[0034] Furthermore, the transfer trolley 1 in this invention is equipped with scrapers 14 at each of its four corners. During the movement of the transfer trolley 1, scrapes off the garbage on the rails to prevent debris from entering the groove wheels and causing the transfer trolley 1 to jam.

[0035] In use, the push rod 53 is pulled upward by the handle 55 to connect the holding furnace connector 54 to the hook on the holding furnace. Then, the lead screw motor drives the lead screw 51 to rotate, causing the seat 52 to move on the lead screw 51, thereby moving the holding furnace into the holding furnace slide rail 4. After sliding on the holding furnace slide rail 4 to the desired position, the drive motor 61 drives the drive shaft 62 to rotate, causing the active optical wheel mechanism 64 and the active positioning slot wheel mechanism 63 to move on the track 2, thereby causing the driven optical wheel mechanism 7 and the driven positioning slot wheel mechanism 8 to move on the track 2. This realizes the movement of the transfer trolley 1 on the track 2, that is, it realizes the mutual transfer and replacement of the holding furnace between the heating station, the transfer trolley 1, and the casting machine, improving the production efficiency of the casting line.

[0036] The above embodiments are only used to explain the inventive concept of this utility model, and are not intended to limit the protection of this utility model. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
