Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically an auxiliary casting device for casting processing. Background Technology

[0002] The core of the casting process is to pour molten metal into a cavity shaped like a workpiece, and after it cools and solidifies, a blank of the workpiece is obtained.

[0003] Gravity casting is one of the most common casting methods in the manufacture of workpieces. It relies entirely on the gravity of the molten metal to fill the mold cavity: the molten iron is poured from the casting ladle into the casting gate, and the liquid naturally flows to fill the entire mold under the action of gravity. In actual operation, a casting ladle is required to transport molten steel to a designated location. Then, the casting ladle will pour the molten steel into the workpiece casting mold at the pouring speed and angle set according to the casting curve within a specified time. During this process, it is not possible to intuitively judge whether the pouring trajectory of the molten steel is aligned with the pouring gate of the workpiece casting mold. It requires the judgment of the operator's experience, which places high demands on the operator's work experience. Based on this, an auxiliary casting device for casting processing is provided.

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.

[0014] Please see Figures 1-3 In this embodiment of the present invention, an auxiliary casting device for casting processing includes a casting assembly 1 consisting of a hanger 101, a casting ladle 102, a flange connecting rod 103, a first reducer 104, and a first handwheel 105. The casting ladle 102 is distributed inside the hanger 101 and is rotatably connected to the hanger 101 via a rotating shaft. The flange connecting rod 103 is fixed to the top of the hanger 101 for connection with a casting robot. The first reducer 104 is installed on the outside of the hanger 101 and its output end is fixedly connected to a rotating shaft on one side of the casting ladle 102. The input end of the first reducer 104 is connected to the first handwheel 105. A flow guiding assembly 2 is provided at the bottom of both sides of the outer wall of the hanger 101. The flow guiding assembly 2 includes an adjustment unit and a receiving hopper 203 located in front of the casting ladle 102. The receiving hopper 203 is used to guide the molten steel poured out of the casting ladle 102. The adjustment unit is used to adjust the horizontal position of the receiving hopper 203 to adapt to the position of the casting port of the workpiece casting mold; The adjustment unit includes a fixed guide rail 201, a movable guide seat 202, a vertical flow guide port 204, an L-shaped connecting arm 205, a connecting guide rail 206, a toothed arm 207, a gear 208, a U-shaped base 209, a second reducer 210, and a second handwheel 211; Fixed guide rails 201 are symmetrically fixed to the bottom of both sides of the hanger 101, and movable guide seats 202 are slidably connected to the outside of fixed guide rails 201; The vertical guide port 204 is fixed to the bottom of the receiving hopper 203. The vertical guide port 204 is aligned with the casting port of the workpiece casting mold to provide guidance for the molten steel to be poured into the casting port. L-shaped connecting arms 205 are symmetrically fixed on both sides of receiving hopper 203. Connecting guide rail 206 is fixed on the side of the two L-shaped connecting arms 205 that are far apart from each other. Connecting guide rail 206 is inserted into the inside of movable guide seat 202 and connected and fixed to movable guide seat 202 by bolts. The horizontal position adjustment of the receiving hopper 203 is achieved by moving the guide seat 202 horizontally based on the fixed guide rail 201. The gear arm 207 is fixed to the top of a movable guide seat 202. The gear 208 is rotatably mounted on the inside of the U-shaped base 209 via a rotating shaft. The U-shaped base 209 is fixed to one side of the hanger 101 by welding. The second reducer 210 is installed on the side of the U-shaped base 209 away from the hanger 101. The output end of the second reducer 210 is fixedly connected to the rotating shaft of the gear 208. The input end of the second reducer 210 is connected to the second handwheel 211. The horizontal movement of the movable guide seat 202 is achieved by rotating the second handwheel 211.

[0015] In this embodiment, it should be noted that the flange connecting rod 103 is connected to the casting robot through the flange structure at its top. The casting robot is an industrial robot in the casting field, such as the BJY200 semi-automatic boom crane casting assist machine and the STJ hydraulic casting robot. It can smoothly and accurately transport the casting ladle containing molten metal to the casting port of the mold. Through the connection structure of the flange connecting rod 103, the overall horizontal state of the flow guiding component 2 can be ensured, that is, the vertical flow guide port 204 can maintain a stable vertical distribution state. The operating procedure for this casting component 1 is as follows: With the help of the casting robot, the overall position of the casting component 1 and the flow guiding component 2 can be moved. During this process, the alignment of the vertical flow guiding port 204 with the casting port of the workpiece casting mold can be observed directly. Compared with the traditional operation that relies on experience to judge the alignment of the molten steel casting curve trajectory with the casting port, the requirements for the work experience of the staff are low, and the alignment operation is more convenient and efficient. When the vertical guide port 204 is aligned with the casting port of the workpiece casting mold, the first handwheel 105 is manually turned. The first handwheel 105 drives the input shaft of the first reducer 104 to rotate. Through the internal parts of the first reducer 104, the output shaft of the first reducer 104 drives the casting ladle 102 to rotate, so that the molten steel inside the casting ladle 102 pours out in a curve and is received by the receiving hopper 203. Finally, the molten steel flows into the casting port of the workpiece casting mold through the vertical guide port 204, realizing the casting operation. Additionally, it should be noted that during the transfer process via the casting robot, the alignment of the vertical guide port 204 with the casting port of the workpiece casting mold can be achieved by adjusting the second handwheel 211. Specifically, by rotating the second handwheel 211, the second handwheel 211 drives the gear 208 to rotate through the transmission of the second reducer 210. The gear 208 pushes the gear arm 207 and one movable guide seat 202 to move horizontally, while the other movable guide seat 202 moves passively. This enables the overall horizontal movement of the receiving hopper 203, the vertical guide port 204, the L-shaped connecting arm 205, and the connecting guide rail 206. In this way, the casting ports of the workpiece casting mold at different distances from the casting ladle 102 can be matched. (It should be added that the top of the receiving hopper 203 has a flared structure. Within the adjustable stroke range of the receiving hopper 203, the top opening of the receiving hopper 203 can fully receive the molten steel.)

[0016] Please refer to this carefully. Figures 1-3 The second handwheel 211 and the first handwheel 105 are located on the same side of the hanger 101, and the second handwheel 211 and the first handwheel 105 are staggered.

[0017] In this embodiment, the second handwheel 211 and the first handwheel 105 are distributed on the same side, which facilitates the operation and adjustment by the staff. It should also be noted that the first reducer 104 and the second reducer 210 are worm gear reducers commonly found on the market.

[0018] Please refer to this carefully. Figures 1-3 The movable guide seat 202 has mounting holes at both ends of its side for bolts to pass through. The side of the connecting guide rail 206 is provided with a threaded hole for bolt thread connection.

[0019] In this embodiment: This structure enables a detachable connection between the connecting guide rail 206 and the movable guide seat 202, facilitating the installation and removal of the receiving hopper 203. In addition, the receiving hopper 203 can be selectively installed at both ends of the connecting guide rail 206 according to the orientation of the casting mold of the casting assembly 1.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
