[0001] The invention relates to the field of pouring, in particular to a double-line pouring system. Background Art

[0002] At present, casting technology is widely used in the production of blanks of metal parts. With the advancement of industrialization, assembly line casting technology has been continuously promoted and applied, and the pouring process is completed by pouring molten metal into neatly arranged sand boxes. At present, the assembly line pouring equipment is usually only able to pour a row of neatly arranged sand boxes, and the molding station usually sends the sand boxes to the pouring station one by one according to a fixed production rhythm. When the pouring station is performing the pouring operation, the sand boxes arranged on the pouring station are not easy to move, which easily leads to the need for the molding station to pause during the pouring to wait for the completion of the pouring operation, which will have a certain impact on production efficiency. Summary of the invention

[0003] In order to improve the efficiency of casting and forming of metal workpieces, the present application provides a double-line casting system.

[0004] The double-line pouring equipment provided in this application adopts the following technical solution:

[0005] A double-line pouring system comprises a molding line and a bidirectional pouring device, wherein a sand box track is arranged on both sides of the bidirectional pouring device, and the molding line is connected to the sand box track; the bidirectional pouring device comprises a mobile platform and a pouring mechanism arranged on the mobile platform, and the pouring mechanism (3) comprises a base, a rotating seat, and a tilting support frame; the base is rotatably connected to the rotating seat, the rotating seat is connected to a rotating drive mechanism for driving it to rotate, and the tilting support frame is used to place a casting ladle and is hinged to the rotating seat.

[0006] By adopting the above technical solution, the molding line completes the preparation work before pouring the sand box, and then sends it to the sand box track for pouring. Two rows of neatly arranged sand boxes are set on both sides of the mobile platform equipped with the pouring mechanism. Through the movement of the mobile platform, the sand boxes in one row are poured one by one; after the pouring is completed, the rotating seat can be rotated 180°, and then the other row of sand boxes can be poured. The double-line pouring equipment pours the sand boxes on one side one by one, while the sand boxes on the other side cooperate with the molding line to receive the sand boxes pushed by the molding line according to the beat, and so on alternately. In this way, the overall molding line can always process the sand boxes according to its own beat, which is not affected by the pouring process and has high pouring efficiency.

[0007] The present application is further configured that the molding line includes a molding station and a molding track, and the side of the molding track exiting the box is connected to the end of the sand box track entering the box, and the side of the molding track entering the box is connected to the end of the sand box track exiting the box.

[0008] By adopting the above technical solution, the sand box between the molding line and the pouring station is circulated to achieve the recycling and reuse of materials.

[0009] The present application is further configured such that the mobile platform is provided with a switching track perpendicular to the sand box track, the pouring mechanism is arranged on the switching track, and can move along the switching track.

[0010] By adopting the above technical solution, the setting of the switching track is used to adjust the position of the pouring mechanism after the rotating seat rotates 180°, so that the pouring mechanism can be better aligned with the gate of the sand box.

[0011] The present application is further configured as follows: the mobile platform is also provided with a support platform, both ends of the support platform extend toward the sand box track, and the support platform is located above the sand box; the support platform is provided with an operating room track, the operating room track is vertically arranged to the sand box track and extends to above the sand box, the operating room is installed on the operating room track and can move along the operating room track.

[0012] By adopting the above technical solution, the operating room can move along the operating room track and can move to the top of the corresponding sand box. That is, when the pouring mechanism pours the sand box on one side, the operating room also moves to that side, so that the operator can clearly judge the position of the gate, which is convenient for the operator to better adjust the position of the pouring mechanism, thereby better pouring the sand box.

[0013] The present application is further configured such that the rotating seat is provided with a bag changing track, a bag changing platform is provided at one end of the pouring track, the bag changing platform is provided with a docking track, and the docking track matches the bag changing track; a bag changing trolley is provided on the docking track.

[0014] By adopting the above technical solution, when the ladle on the pouring mechanism is about to be used up, the ladle filled with molten metal is placed on the ladle changing trolley through the lifting device, and the pouring machine is controlled to move to one side of the ladle changing platform so that the ladle changing track and the docking track are aligned with each other, and the tilting support frame continues to move downward so that the counterweight wheel contacts the upper surface of the rotating seat until the locking assembly is disengaged from the fixed rod. The lifting device moves the empty ladle away, and the full ladle is immediately pushed into the tilting support frame. The ladle changing process is fast and convenient, and the pouring efficiency is improved.

[0015] The present application is further configured such that a bracket and a support roller are provided at the lower portion of the tilting support frame, there are two brackets, the support roller is located between the two brackets, the support roller is rotatably mounted on the tilting support frame, and a locking assembly for locking the ladle fixing rod is provided at the tail of the bracket.

[0016] By adopting the above technical solution, the support roller is used to support the front end of the ladle, and the bracket supports the rear end of the ladle, and the tilting support frame and the ladle are fixed to each other through the locking component; when the ladle is installed, since the support roller can roll, the front end of the ladle can be easily pushed onto the support roller during the process of pushing the ladle into the rotary tilting pouring mechanism. Similarly, when the empty ladle is replaced from the rotary tilting pouring mechanism, the front end of the ladle can be easily detached from the tilting support frame.

[0017] The present application is further configured such that the locking assembly includes a slot arranged at the tail of the bracket and a hook hinged to the tail of the bracket, wherein the hook is located at the position of the slot, and the hook is connected to a counterweight wheel, and the counterweight wheel can be driven by gravity to hook the hook onto the fixing rod of the ladle.

[0018] By adopting the above technical solution, when installing the ladle, the front end of the ladle is pushed to the supporting roller, and the fixing rod set at the rear end of the ladle is inserted into the slot. When the tilting support frame is not lifted, the counterweight wheel contacts the rotating seat, thereby driving the buckle to flip toward the side of the slot, so that the hook and the fixing rod are separated from each other. When the tilting support frame flips, the counterweight wheel gradually disengages from the tilting support frame, driving the hook to gradually rotate until it hooks the fixing rod, thereby locking the fixing rod. The locking and unlocking are automatically completed as the tilting support frame flips, and no manual operation is required.

[0019] The present application is further configured such that two support arms are provided on the upper part of the rotating seat, the tilting support frame is hinged to the upper ends of the two support arms and rotates around the upper ends of the support arms, and the rotation axis of the tilting support frame and the support arms is close to the position of the ladle outlet nozzle.

[0020] By adopting the above technical solution, two support arms are arranged on the upper part of the rotating seat, the tilting support frame is hinged to the upper ends of the two support arms and rotates around the upper ends of the support arms, and the rotation axis of the tilting support frame and the support arms is close to the position of the ladle outlet nozzle.

[0021] The present application is further configured such that the tilt support frame is provided with two U-shaped grooves, the openings of the U-shaped grooves face the support arm, and when the tilt support frame is lowered, the U-shaped grooves can be buckled onto the support arm; a storage groove is provided on the side of the support arm facing the tilt support frame, and a tilt drive structure for driving the tilt support frame to rotate is installed in the storage groove.

[0022] By adopting the above technical solution, the driving structure is installed in the space enclosed by the U-shaped groove and the storage groove, which can provide good protection for the driving structure and prevent molten metal, dust, etc. from affecting the driving structure.

[0023] The present application is further configured such that the power elements for the pouring mechanism to move along the pouring track, the pouring mechanism to move along the switching track, and the operating room to move along the operating room track are all driven by motors.

[0024] By adopting the above technical solution and using the motor as the driving element, the operator can accurately control the precise movement of the corresponding mechanism and reduce the control difficulty. At the same time, the motor can use a servo motor to improve the automation level of the overall equipment.

[0025] To sum up, the present application has the following advantages: when one row of sand boxes is poured after another row of sand boxes is poured, the row of sand boxes that has been poured first can stay on the sand box track for a period of time and then be evacuated, so that the molten metal in the sand boxes can be properly cooled and hardened. In this way, the quality of metal forming will not be affected by the external force when the sand boxes move, thereby improving product quality; at the same time, the bag changing speed is fast, the pouring mechanism can realize uninterrupted pouring, and realize circular production through the molding line.

[0037] Embodiment 1:

[0038] Reference Figure 1 A double-line pouring system includes a molding line 2 and a bidirectional pouring device; the bidirectional pouring device includes a pouring track 1 and a mobile platform 11 arranged on the pouring track 1, the mobile platform 11 can move along the pouring track 1, and the sand box track 16 has two groups respectively located on both sides of the mobile platform 11, which are used to arrange the sand boxes 5 neatly; the bidirectional pouring device can pour molten metal into the sand boxes 5 neatly arranged on both sides.

[0039] The molding line 2 includes a molding track and various molding stations arranged along the molding track, which are used to complete the molding work and process the sand box. After the processing is completed, the sand box 5 to be poured is transported to the sand box track 16; in this embodiment, one end of the molding track exiting the box is connected to the end of the sand box track 16 entering the box, and the other end of the molding track is connected to the end of the sand box track 16 exiting the box, so that the sand box 5 can circulate between the molding track and the sand box track 16.

[0040] like Figure 2 , 3 As shown, the mobile platform 11 is provided with a pouring mechanism 3 and an operating room 13. A lighting lamp 131 is provided on the side of the operating room 13 facing the pouring mechanism 3. The mobile platform 11 is provided with a switching track 111 perpendicular to the pouring track 1. The pouring mechanism 3 is arranged on the switching track 111 and can move along the switching track 111, so that the pouring mechanism 3 can move close to one of the two rows of sand boxes 5.

[0041] Reference Figure 4 , 5As shown, the pouring mechanism 3 includes a base 31, a rotating base 32, and a tilting support frame 33; the base 31 cooperates with the switching track 111, and the base 31 and the rotating base 32 are rotatably connected. The rotation axis between the base 31 and the rotating base 32 is vertically arranged, so that the rotating base 32 can rotate around the vertical axis on the base 31. The rotating base 32 can be driven by a servo motor or hydraulically, which will not be expanded in this embodiment. Two support arms 321 are arranged on the upper part of the rotating base 32, and a connecting rod 322 is fixed between the two support arms 321, and the connecting rod 322 is close to the upper part of the support arm 321. The tilting support frame 33 is hinged to the upper end of the two support arms 321, so that the tilting support frame 33 can rotate around the upper end of the support arm 321. The tilting support frame 33 is used to fix the ladle 4. When the tilting support frame 33 rotates around the upper end of the support arm 321, the molten metal in the ladle 4 can be poured out. The ladle 4 is barrel-shaped, and the rotation axis of the tilting support frame 33 and the support arm 321 is located outside the barrel of the ladle 4, and the rotation axis of the tilting support frame 33 and the support arm 321 is located at the position of the liquid outlet nozzle 41 of the ladle 4, so that the liquid outlet nozzle 41 on the ladle 4 can be closer to the gate of the sand box 5, making the landing point of the molten metal more controllable.

[0042] U-shaped grooves 335 are provided on both sides of the tilt support frame 33, and the openings of the U-shaped grooves 335 face the support arm 321. When the tilt support frame 33 is lowered, the U-shaped grooves 335 can be buckled into the support arm 321 to cover the support arm 321; a storage groove 323 is provided on the side of the support arm 321 facing the tilt support frame 33, and a tilt cylinder 35 is installed in the storage groove 323. One end of the tilt cylinder 35 is hinged to the rotating seat 32, and the other end is hinged to the tilt support frame 33. The tilt support frame 33 can be driven to rotate by the extension and retraction of the cylinder 35. Since the cylinder 35 is in the space enclosed by the storage groove 323 and the U-shaped groove 335, the cylinder 35 can be well protected.

[0043] Two brackets 332 are provided at the lower part of the tilting support frame 33 for carrying the ladle 4. A slot 333 is provided at the tail of the bracket 332, and a fixing rod 42 is provided at the position of the ladle 4 corresponding to the slot 333; a hook 334 is hinged at the tail of the bracket 332, and the hook 334 is connected to a counterweight wheel 336. When the tilting support frame 33 rotates, the counterweight wheel 336 leaves the rotating seat 32, and drives the hook 334 to rotate and hook the fixing rod 42 under the action of gravity, thereby locking the ladle 4 and the tilting support frame 33.

[0044] As shown in the figure, a ladle changing track 324 is provided on the rotating seat 32, and the ladle changing track 324 is located between the two brackets 332. The ladle changing track 324 is used in conjunction with the ladle changing trolley 15, so that the ladle changing trolley 15 carries the ladle 4, sends the ladle 4 to the position of the bracket 332, and makes the fixing rod 42 on the ladle 4 enter into the card slot 333, so that the ladle 4 can be quickly sent to the tilting support frame 33.

[0045] Reference Figure 6 , 7 The tilting support frame 33 is also provided with a support roller 331, which is used to support the bottom of the ladle 4 and cooperate with the bracket 332 to achieve stable support of the ladle 4 by the tilting support frame 33. Since the cooperation between the support roller 331 and the ladle 4 is rolling friction, it is relatively labor-saving to put a full ladle 4 into the tilting support frame 33 or replace an empty ladle 4 from the tilting support frame 33.

[0046] Reference Figure 1 In order to further improve the accuracy of the pouring process, a funnel 36 is provided on the rotating seat 32. The funnel 36 is fixed to the connecting rod 322 and is located below the liquid outlet nozzle 41 of the ladle 4. The lighting direction of the lighting lamp 131 in the operating room 13 is aligned with the lower part of the funnel 36. In the process of driving the ladle 4 to tilt, the position of the end of the liquid outlet nozzle 41 will change. Through the setting of the funnel 36, the molten metal is first poured into the funnel 36, and then poured into the pouring gate through the funnel 36. This can avoid the change of the position of the liquid outlet nozzle 41 causing the change of the falling point of the molten metal. In this way, when controlling the pouring mechanism 3, the operator only needs to control the angle of the rotating seat 32 and the distance between the mobile pouring mechanism 3 and the sand box 5, so that the lower part of the funnel 36 is aligned with the pouring gate, and the molten metal can be accurately poured into the pouring gate, reducing the difficulty of alignment.

[0047] Reference Figure 2 , 8 A bag-changing platform 14 is provided at one end of the pouring track 1, and a docking track 141 is provided on the bag-changing platform 14. A bag-changing trolley 15 is provided at the bag-changing platform 14, and the bag-changing trolley 15 can move along the docking track 141. The specifications of the docking track 141 and the bag-changing track 324 are the same. That is, when the mobile platform 11 moves toward the bag-changing platform 14 with the pouring mechanism 3, and the end of the bracket 332 faces the bag-changing platform 14, and the mobile platform 11 moves to the bag-changing platform 14 to the extreme position, the docking track 141 can be aligned with the bag-changing track 324, so that the bag-changing trolley 15 can move along the docking track 141 to the bag-changing track 324, and the ladle 4 is sent to the position where the bracket 332 is located, and the tilting support frame 33 is driven to lift the bracket 332, and the fixed card on the ladle 4 is inserted into the card slot 333. As the tilting support frame 33 continues to flip, the locking mechanism locks the ladle 4 and the tilting support frame 33 with each other.

[0048] Reference Figure 2 The mobile platform 11 is also provided with a support platform 12, both ends of which extend toward the sand box track 16. After the sand box 5 is moved to the sand box track 16, the support platform 12 is located above the sand box 5. The support platform 12 is provided with an operating room track 121, which is arranged vertically with the pouring track 1 and extends to the top of the sand box 5. The operating room 13 is installed on the operating room track 121 and can move along the operating room track 121. There is an operating table in the operating room 13, through which the mobile platform 11 can be controlled to move along the pouring track 1, the pouring mechanism 3 can move along the switching track 111, the operating room 13 can move along the operating room track 121, the rotating seat 32 can rotate relative to the base 31, and the tilting support frame 33 can be flipped. It should be noted that the power elements for the pouring mechanism 3 to move along the pouring track 1, the pouring mechanism 3 to move along the switching track 111, and the operating room 13 to move along the operating room track 121 are driven by a motor and are realized by the cooperation of gears and racks; for example, the driving structure between the mobile platform 11 and the pouring track 1, wherein the motor can be installed on the mobile platform 11, and a gear driven by the motor is installed on the mobile platform 11, and a rack is fixed in the middle of the pouring track 1, and the movement of the mobile platform 11 is realized by the cooperation of the gear and the rack.

[0049] According to the production requirements, one row of the sand boxes 5 can be poured first, and then the other row of the sand boxes 5 can be poured. During the pouring process, the liquid outlet 41 is directed toward one row of the sand boxes 5 by the rotation of the rotating seat 32, and the metal liquid is aligned with the gate set on the sand box 5 by the movement of the base 31 along the switching track 111. The metal liquid is poured into each sand box 5 one by one by the movement of the mobile platform 11 along the pouring track 1. Since the operating room 13 can move along the operating room track 121, when pouring one row of the sand boxes 5, as the rotating seat 32 rotates, the operating room 13 can move along the operating room track 121, so that the operating room 13 moves to the top of the row of sand boxes 5 that needs to be poured, so that the gate position that needs to be poured is located in front of the operating room 13, and the operator can clearly judge the position between the metal liquid landing point and the gate through the observation window, and make adaptive adjustments to the pouring mechanism 3 to ensure that the metal liquid can be accurately poured into the gate.

[0050] When the ladle 4 on the pouring mechanism 3 is about to be used up, the ladle replacement process is as follows: the ladle 4 filled with molten metal is placed on the ladle replacement trolley 15 through the lifting device, and the mobile platform 11 is controlled to move to one side of the ladle replacement platform 14, so that the ladle replacement track 324 and the docking track 141 are aligned with each other, and the tilting support frame 33 is continuously lowered, so that the counterweight wheel 336 contacts the upper surface of the rotating seat 32 until the locking assembly is separated from the fixed rod 42, and the lifting device lifts away the empty ladle 4, and immediately pushes the full ladle 4 into the tilting support frame 33 through the ladle replacement trolley 15, and the ladle replacement process is fast and convenient. The above-mentioned lifting device can be a crane, a handling robot, etc.

[0051] The working principle of the present application is as follows: the operator enters the operating room 13 and controls the movement of each mechanism of the equipment through the control console in the operating room 13; since the pouring mechanism 3 can rotate, the pouring mechanism 3 can rotate 180° to realize pouring of the sand boxes 5 arranged on both sides of the pouring track 1. During pouring, according to the actual production needs, you can choose to pour one row of sand boxes 5 first, and then pour the other row; you can also pour one of the sand boxes 5 on one side first, and then pour one of the sand boxes 5 on the other side, alternately. The present application is explained by first pouring one row of sand boxes 5. First, the operating room 13 is moved to the upper part of the sand box 5 of the row to be poured, and at the same time, the liquid outlet nozzle 41 of the pouring mechanism 3 is controlled to rotate with the rotating seat 32 to the side where the pouring operation is required. The liquid outlet nozzle 41 is located in front of the operating room 13. The operator adjusts the pouring mechanism 3 according to the position of the funnel 36 and the gate quality inspection, so that the lower part of the funnel 36 is aligned with the gate, and then controls the tilting support frame 33 to flip, pours the molten metal into the funnel 36, and allows the molten metal to enter the gate through the funnel 36 to complete the pouring of one sand box 5; then the mobile platform 11 moves to align the lower part of the funnel 36 with the position of the next sand box 5 to be poured, and pours the next sand box 5 until the pouring of the entire row of sand boxes 5 is completed; after completion, the operating room 13 moves to the upper part of another row of sand boxes 5, and controls the pouring mechanism 3 to move to complete the pouring of the next row of sand boxes 5. During the pouring process, if the molten metal in the ladle 4 is poured out, the mobile platform 11 moves to one end of the pouring track 1, takes away the empty ladle 4, and replaces it with a ladle 4 filled with molten metal to continue pouring. The entire ladle replacement process is quick and convenient. Since the pouring mechanism 3 can realize double-line pouring, when the sand box 5 of one of the sand box tracks 16 is stationary and pouring is carried out, the other row of sand box tracks 16 is used to connect the molding line 2, and the molding line 2 can continuously send the sand box 5 to the sand box track 16 according to the beat; since the time used to pour a sand box 5 is shorter than the time used to mold a sand box 5, the alternation of the two sand box tracks 16 can enable the molding line 2 to continue to perform molding work regularly without pausing due to ladle replacement or other reasons of the pouring equipment, thereby improving production efficiency.

[0052] Embodiment 2:

[0053] Different from the first embodiment, the flask 5 flows unidirectionally from the molding line 2 to the flask track 16 , that is, the flask 5 is sent to the flask track 16 for pouring at the molding line 2 according to the beat, and is sent out from the flask track 16 after the pouring is completed.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
