Description

Technical Field

[0001] The present invention relates to the technical field of guide casting, and particularly to a casting device and a casting method for a guide. Background Art

[0002] The guide is cast by the investment precision casting vacuum melting and pouring process. The production of the guide uses a vacuum induction melting furnace for melting and pouring. The vacuum induction melting furnace is a complete set of vacuum smelting equipment that uses the intermediate frequency induction heating principle to melt metals under vacuum conditions. It is suitable for scientific research and production departments to melt and cast nickel-based, iron-based, cobalt-based and their special steels, precision alloys, neodymium iron boron, reactive metals, superalloys, hydrogen storage materials, magnetic materials, etc. under vacuum or protective atmosphere.

[0003] In terms of the quality of castings, due to the poor temperature control accuracy of traditional casting equipment, especially during the shell baking and metal liquid melting processes, the temperature fluctuations result in uneven shell strength and easy segregation of the metal liquid composition. This not only causes the surface of the casting to be rough, with defects such as sand holes and air holes, but also greatly weakens the mechanical properties of the casting, making the guide prone to failures during actual use, seriously affecting the stability and service life of the equipment. In terms of production efficiency, the automation level of the existing technology is low. From the handling and positioning of the shell sand box to the pouring of the metal liquid, a large amount of manual operation is relied on. Manual operation is not only slow, but also easily affected by the proficiency and fatigue state of workers, resulting in poor continuity of the production process and a long overall production cycle, making it difficult to meet the requirements of large-scale and high-efficiency modern production. And the casting process mainly includes processes such as molding, shell baking, batching, vacuum melting, pouring, discharging, and sand cleaning and cutting. Summary of the Invention

[0016] Step 1: Place the mold for casting the guide in the transport vehicle, and the transport vehicle is sent into the trolley-type resistance furnace along the first slide rail. The transport vehicle is set to pass through the track of the first slide rail and exit from one side of the trolley-type resistance furnace. When exiting, the first drive motor drives the first rotating shaft to engage the first meshing gear with the tooth slot, causing the first sliding plate to slide in the guide slot, driving the first movable door to open through the connecting plate, and the transport vehicle will stop on one side of the mechanical gripper arm;

[0017] Step 2: The mechanical gripper arm grabs the heated raw material on the transport vehicle and places the heated raw material on the second sliding plate of the conveying mechanism on one side of the pouring box. The second drive motor drives the second rotating shaft to make the second sliding plate slide along the second slide rail, and transports the raw material to the entrance of the pouring box;

[0018] Step 3: Use an air pump to open the sealed door of the pouring box through the air rod and the connecting block. The first transmission shaft on one side of the synchronous motor drives the semi-circular gear to rotate. Through the second meshing gear and the second transmission shaft, the toothed plate moves, driving the slider to slide in the chute of the L-shaped plate to adjust the position of the placement plate. At the same time, the first telescopic rod drives the first clamping plate to clamp the mold at the entrance of the pouring box, and then the mold is placed on the lifting table. The second telescopic rod and the second support plate will clamp the mold. At this time, the air pump, the air rod and the connecting block will reset the sealed door. During this period, the first air extraction pump will extract the gas in the pouring box through the first air transport pipe, and the staff will seal the blanking chute with the sliding rod, the pulling plate, the connecting rod and the closing plate, so that the pouring box is in a vacuum state;

[0019] Step 4: Open the top cover of the vacuum induction melting furnace, start the first servo motor to drive the turret to adjust the position, start the second servo motor to drive the crucible to rotate through the pulley drive, turn on the vacuum induction melting furnace to melt the metal raw material, and the second air extraction pump extracts the vacuum of the vacuum induction melting furnace through the second air transport pipe. The staff operates the sliding rod, the pulling plate, the connecting rod and the closing plate in the reverse direction, so that the closing plate opens, so that both the pouring box and the vacuum induction melting furnace are in a vacuum state;

[0020] Step 5: Start the first servo motor, drive the turret to adjust the position through the second connecting column and the rotating rod; start the second servo motor, drive the crucible to rotate through the first rotating shaft, the pulley and the second rotating shaft, so that the melted liquid metal is poured into the mold in the pouring box, and wait for the liquid metal to cool and solidify in the mold;

[0021] Step 6: Use an air pump to open the sealed door of the pouring box through an air rod and a connecting block. The first transmission shaft on one side of the synchronous motor drives the semi-circular gear to rotate. Through the second meshing gear and the second transmission shaft, the toothed plate moves, driving the slider to slide in the chute of the L-shaped plate to adjust the position of the placement plate. At the same time, the first telescopic rod drives the first clamping plate to clamp the mold at the inlet of the pouring box. The first telescopic rod and the first clamping plate on the other side of the toothed plate will clamp the cooled mold. The first transmission shaft on one side of the synchronous motor drives the semi-circular gear to rotate. Through the second meshing gear and the second transmission shaft on one side of the mechanism, the toothed plate moves in the reverse direction, putting the mold near the conveying inlet onto the lifting table, and the cooled mold on the side away from the conveying mechanism will be sent out of the pouring box.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. With the base as the basic support, the first slide rail fixedly connected to its upper surface cooperates with the trolley-type resistance furnace, enabling the transport vehicle of the trolley-type resistance furnace to move along the track. At the same time, the lifting mechanism on the trolley-type resistance furnace can accurately control the opening and closing of the first movable door to achieve preheating treatment of the mold. The mechanical gripper arm in the material transfer component is erected between the trolley-type resistance furnace and the pouring box, undertaking the grasping and transfer work of the mold, raw materials, and liquid metal.

[0024] 2. Based on the mounting plate, the conveying mechanism drives the second rotating shaft by the second driving motor, and cooperates with the second slide rail to make the second sliding plate slide, accurately conveying the mold or raw materials to the inlet of the pouring box. Its sealed door realizes opening and closing under the coordinated action of an air pump, an air rod, and a connecting block, ensuring internal sealing. And the gas treatment mechanism maintains a stable gas environment in the pouring box and the vacuum induction melting furnace through the first air extraction pump, the first air conveying pipe, the clean gas box, the second air extraction pump, and the second air conveying pipe.

[0025] 3. Relying on the mounting table, the melting component fixes the vacuum induction melting furnace with the first connecting column. The first servo motor and the second servo motor respectively drive the turret and the crucible to achieve efficient melting of metal raw materials. Driven by the synchronous motor, the material grasping mechanism drives the toothed plate to move through the first transmission shaft, the semi-circular gear, the second transmission shaft, and the second meshing gear, and cooperates with the first telescopic rod and the first clamping plate to accurately adjust and clamp the mold. The hydraulic tank of the lifting mechanism provides power, and the hydraulic rod pushes the lifting table.
