Description

Technical Field

[0001] The invention relates to the technical field of casting equipment, and in particular to a double-side tilting pouring system and a pouring method. Background Art

[0002] Casting is the process of obtaining metal castings by certain methods. A pouring machine is used to pour molten iron into a sand mold. The molten iron is cooled in the sand mold to obtain a casting blank. Pouring machines can be roughly divided into two categories according to the way the molten iron flows out: bottom pouring machines and tilting pouring machines. A tilting pouring machine refers to a pouring machine that tilts the ladle or container for pouring.

[0003] During the casting operation on the production line, the sand molds formed by the sand mold molding machine are ejected one by one from the sand mold production outlet and pushed toward the pouring machine through the sand mold sliding channel. The existing tilting pouring machine is generally installed near the sand mold sliding channel so that when pouring, the ladle nozzle of the ladle is aligned with the sand box of the sand mold corresponding to the position of the sand mold sliding channel to carry out the pouring operation.

[0004] However, during the pouring process of the existing tilting pouring machine, since the position of the pouring port of the ladle does not coincide with the rotation center, the ladle needs to be continuously raised while tilting to compensate for the descent of the pouring port of the ladle and keep the ladle moving horizontally in the opposite direction, which makes the transmission structure complicated and automatic control difficult. In addition, due to its structural limitations, the existing tilting pouring machine can only rotate on one side, and it is necessary to ensure that the pouring port position of the sand box to be poured is fixed, that is, it is only suitable for pouring work under the condition that the equipment rotates to one side and the pouring port position is fixed, and the layout of the pouring line is strictly required, and the pouring efficiency is low. Summary of the invention

[0005] In order to solve the technical problems in the above-mentioned background technology that the existing pouring machine is affected by its structure and working principle, resulting in low pouring efficiency, complex transmission structure and difficult automatic control, the present invention provides a double-side tilting pouring system and pouring method.

[0006] The technical solution of the present invention is as follows:

[0007] The present invention provides a double-side tilting pouring system, comprising a guide rail truss, and further comprising:

[0008] The three-axis moving device is slidably arranged on the guide rail truss, and has the freedom of movement in three directions: X-axis, Y-axis and Z-axis;

[0009] The bracket assembly is fixedly mounted on the three-axis moving device and moves in space with the three-axis moving device. It contains a servo reduction motor. The output shaft of the servo reduction motor is fixedly connected with the bracket. The bracket is an I-shaped structure, and a hook is fixedly mounted at each of the four corners of the bracket.

[0010] The iron ladle has three first hanging points and one second hanging point fixedly arranged on both side walls. The three first hanging points on the same side are arranged according to the three corners of a right triangle. The first hanging points cooperate with the hooks to realize the quick connection between the hanger assembly and the iron ladle. The coordinated use of the three-axis moving device and the servo reduction motor enables the iron ladle to have four-axis movement, which can conveniently and quickly change the position of the iron ladle, meet the pouring work requirements when the three-dimensional position of the sand box pouring mouth is not fixed, and no fixed-point pouring is required. The overall structure is simple, flexible, easy to control, and effectively improves the work efficiency. At the same time, both sides of the iron ladle are provided with first hanging points that cooperate with the hanger assembly. With the use of the first conveyor roller, the sand box to be poured on the designated second conveyor roller can be poured as needed to realize double-sided tilting pouring, enriching the pouring line layout.

[0011] The first conveyor roller is used to convey the molten iron ladle and is located below the guide rail truss. The first conveyor roller is arranged along the width direction of the guide rail truss.

[0014] Preferably, the hook is a stepped columnar structure, and a stepped groove cooperating with the hook is provided at the bottom of the first hanging point, which can effectively ensure the connection stability between the ladle and the hook.

[0015] Preferably, the three-axis moving device includes a moving beam slidably arranged on the top of the guide rail truss, the moving beam extends along the width direction of the guide rail truss, and the moving beam moves along the length direction of the guide rail truss under the drive of the driving unit. It can drive the hanger assembly to move along the guide rail truss, and transmit and disperse force through the guide rail truss, thereby improving the load-bearing capacity and stability.

[0016] Preferably, the bottom of the movable crossbeam is fixedly connected to a hanger, the bottom of the hanger is fixedly provided with a first slide rail and is equipped with a movable drive unit, the first slide rail is parallel to the movable crossbeam, the movable drive unit is fixedly connected to a lifting mechanism, and the lifting mechanism is fixedly connected to the movable crossbeam through the hanger. The setting of the hanger and the first slide rail at its bottom and the movable drive unit improves the supporting strength and supporting stability of the lifting mechanism, while ensuring the ability of the lifting mechanism to move laterally, thereby expanding the working range and flexibility of the hanger assembly.

[0018] Preferably, a flow-following inoculation system is slidably provided on the movable crossbeam, and the flow-following inoculation system includes a filling mechanism and a two-axis driving mechanism. The filling mechanism is connected to the two-axis driving mechanism and can move synchronously with the hanger assembly to achieve synchronous addition of the inoculant during pouring when the three-dimensional position of the sand box gate is not fixed.

[0019] Preferably, two first conveying rollers are provided, and the two first conveying rollers are arranged in sequence along the width direction of the guide rail truss. The two first conveying rollers are connected by a third conveying roller, which is used to convey the molten iron ladle to the front of the hanger assembly, so as to facilitate the connection between the hanger assembly and the molten iron ladle.

[0020] Preferably, the two second conveyor rollers are relatively distributed on both sides of the center line of the guide rail truss in the length direction, and there is space between the two second conveyor rollers to allow the hanger assembly and the ladle to pass as a whole, so as to meet the working requirements of bilateral tilt casting and optimize the layout of the casting line.

[0021] The present invention provides a casting method, which is as follows:

[0022] According to the position of the second conveyor roller where the sand box to be poured is located, the first conveyor roller on the same side is started to convey the molten iron ladle to the front of the initial position hanger assembly;

[0023] The three-axis moving device controls the hook to move horizontally from the side of the ladle to the bottom of the corresponding first hanging point, and then lifts the ladle by lifting the hanging bracket assembly;

[0024] The moving crossbeam moves toward the direction close to the sand box to be poured, and moves the lifted molten iron ladle between the two second conveyor rollers and to one side of the sand box to be poured. The flow-following inoculation system moves synchronously with the moving crossbeam, and the servo reduction motor is started, driving the molten iron ladle to tilt and pour through the hanging bracket, and the inoculant is added synchronously during the pouring process.

[0025] It can be seen from the above technical solutions that the advantages of the present invention are:

[0026] 1. Through the cooperation of the first hanging point and the hook, the quick connection between the hanger assembly and the ladle is realized. The coordinated use of the three-axis moving device and the servo reduction motor enables the ladle to have four-axis movement, which can easily and quickly change the position of the ladle, meet the pouring work requirements when the three-dimensional position of the sand box gate is not fixed, and no fixed-point pouring is required.

[0042] Example 1

[0043] In a typical embodiment of the present invention, Figure 1-Figure 9As shown, a double-side tilting pouring system is proposed, including: a guide rail truss 2, a first conveyor roller 9 and a second conveyor roller 10, wherein two first conveyor rollers 9 and two second conveyor rollers 10 are provided, wherein the two first conveyor rollers 9 are located below the guide rail truss 2, and the two first conveyor rollers 9 are sequentially arranged along the width direction of the guide rail truss 2, and the two first conveyor rollers 9 are arranged in a straight line as a whole, and the two first conveyor rollers 9 convey relative to each other, and the adjacent ends of the two first conveyor rollers 9 are located on both sides of the center line of the guide rail truss 2 in the length direction, and the two first conveyor rollers 9 are connected by a third conveyor roller 11, and the third conveyor roller 11 is located in front of the initial position hanger assembly 4, and is used to transport the molten iron ladle 9 to the front of the hanger assembly 4;

[0044] The two second conveyor rollers 10 are also located below the guide rail truss 2, and the two second conveyor rollers 10 are arranged along the length direction of the guide rail truss 2. The two second conveyor rollers 10 are relatively distributed on both sides of the center line of the length direction of the guide rail truss 2. The two second conveyor rollers 10 have the same conveying direction and are used for conveying the sand box 1 to be poured.

[0045] The second conveyor rollers 10 are perpendicular to the first conveyor rollers 9 , and there is a space between the two second conveyor rollers 10 for allowing the rack assembly 4 and the iron ladle 3 to pass through as a whole.

[0046] like Figure 1-Figure 3 As shown, a movable crossbeam 5 is slidably provided on the guide rail truss 2, and the movable crossbeam 5 is slidably connected to the top of the guide rail truss 2. The movable crossbeam 5 extends along the width direction of the guide rail truss 2, and the movable crossbeam 5 can move along the length direction of the guide rail truss 2 driven by the driving unit.

[0047] In this embodiment, the main body of the guide rail truss 2 is a truss structure, a guide rail is fixedly provided on the top of the truss structure along its length direction, the movable crossbeam 5 is slidably connected to the guide rail, and the movable crossbeam 5 moves under the drive of the driving unit.

[0048] The bottom of the movable crossbeam 5 is fixedly connected with a hanger, the bottom of the hanger is fixedly provided with a first slide rail and is equipped with a movable drive unit, the first slide rail extends along the width direction of the guide rail truss 2, that is, the first slide rail is parallel to the movable crossbeam 5, the movable drive unit cooperates with the first slide rail, the lifting mechanism 6 is fixedly connected with the movable drive unit, the lifting mechanism 6 includes a column and a lifting drive unit, the column is vertically arranged, the lower end of the column is fixedly connected with the movable drive unit, the column is fixedly provided with a second slide rail, the lifting drive unit cooperates with the second slide rail on the column, and the bracket assembly 4 is fixedly installed on the lifting drive unit.

[0049] The moving crossbeam 5, the lifting mechanism 6, the hanger, the first slide rail on the hanger, and the mobile drive unit cooperate together to form a three-axis moving device (i.e., X, Y, and Z axes) to drive the hanger assembly 4 and control the movement of the hanger assembly 4 along the length, width, and vertical directions of the guide rail truss 2.

[0050] It can be understood that the drive unit, mobile drive unit and lifting drive unit in this embodiment are motor-driven screw substructures, and may be other structures in other embodiments. The specific structure can be determined according to actual needs, and no excessive restrictions are made here.

[0051] The lifting mechanism 6 is fixedly connected to the moving crossbeam 5 through the hanger. The setting of the hanger and the first slide rail at its bottom and the mobile drive unit improves the supporting strength and supporting stability of the lifting mechanism 6, while ensuring the ability of the lifting mechanism 6 to move laterally, thereby expanding the working range and flexibility of the hanger assembly 4.

[0052] like Figure 8 As shown, the bracket assembly 4 includes a servo reduction motor 41 and a bracket 42. The servo reduction motor 41 is fixedly connected to the lifting drive unit on the lifting mechanism 6, and can move vertically along the column under the drive of the lifting drive unit. The bracket 42 is fixedly connected to the output shaft of the servo reduction motor 41 through a reducer, a coupling and other structures, and the bracket 42 can rotate around the axis under the drive of the servo reduction motor 41.

[0053] like Fig. 9 As shown, the hanger 42 is an I-shaped structure with four corners, each of which is fixed with a hook 43, which is used to be connected with the ladle 3, and the center position of the hanger 42 is fixedly connected to the output shaft of the servo reduction motor 41.

[0054] like Figure 5-Figure 7 As shown, three first hanging points 31 and one second hanging point 32 are fixedly provided on both sides of the ladle 3, and the three first hanging points 31 on the same side are arranged according to the three corners of a right triangle. Specifically, among the three first hanging points 31 on the same side, two first hanging points 31 are close to the bottom of the ladle 3, and the other first hanging point 31 is close to the pouring port of the ladle 3; the second hanging point 32 is fixedly set at the center position of the side wall of the ladle 3.

[0055] The hook 43 is a stepped columnar structure, and the end of the hook 43 has the largest diameter. Specifically, the hook 43 includes a first column and a second column. The first body is horizontally fixed on the bracket 42. The diameter of the second column is larger than that of the first column. The second column is fixed at the end of the first column to play a limiting role. Correspondingly, a stepped groove is provided at the bottom of the first hanging point 31. The shape and size of the stepped groove match the hook 43, and the hook 43 can be snapped into the stepped groove.

[0056] The first hanging point 31 and the second hanging point 32 on both sides of the molten iron ladle 3 are arranged relatively and the positions correspond one to one. The first hanging point 31 is used to cooperate with the hanging bracket assembly 4 to realize the tipping of the molten iron ladle 3; the second hanging point 32 is used to cooperate with the lifting device to lift the molten iron ladle 3 to the first conveyor roller 9 or remove the molten iron ladle 3 from the first conveyor roller 9 through the lifting device.

[0057] After pouring is completed, the ladle needs to be lifted out by a special hanger (conventional configuration of ladle) through the second hanging point 32 to pour out the remaining molten iron that has not been poured. If the ladle is provided with four first hanging points 31, when the second hanging point 32 is used to pour out the remaining molten iron, the special hanger will interfere with the fourth first hanging point 31 and the molten iron cannot be poured. Therefore, four hanging points are set for the hanger, and three hanging points are set on both sides of the ladle. This is mainly to ensure that no matter which direction the ladle spout is facing, the three hanging points can be guaranteed to be in close contact, while at the same time ensuring that the ladle can smoothly pour out the remaining molten iron.

[0058] With the cooperation of the three-axis moving device, the hanger assembly 4 and the ladle 3, the ladle 3 has four-axis movement, which can easily and quickly change the position of the ladle 3, meeting the casting work requirements when the three-dimensional position of the sand box pouring mouth is not fixed. The overall structure is simple, flexible, and easy to control, which effectively improves the work efficiency. In addition, both sides of the ladle 3 are provided with hanging points that cooperate with the hanger assembly 4. With the use of the first conveyor roller 9, the sand boxes 1 to be poured on both sides of the hanger assembly 4 can be cast, enriching the casting line layout.

[0059] The pouring system further includes a control room 7 and a flow inoculation system 8, wherein the control room 7 is located below the guide rail truss 2 and on the side of the first conveyor roller 9 away from the second conveyor roller 10, and is used for controlling the pouring work.

[0060] There are two flow-inoculation systems 8, both of which are slidably arranged on the moving beam 5. The flow-inoculation system 8 includes a filling mechanism and a two-axis driving mechanism. The two-axis driving mechanism includes an X-axis driving unit and a Y-axis driving unit. The X-axis driving unit is slidably arranged on the moving beam 5. The X-axis driving unit is a lead screw substructure driven by a motor. The Y-axis driving unit is connected to the X-axis driving unit. The Y-axis driving unit is also a lead screw substructure driven by a motor. The filling mechanism is installed on the Y-axis driving unit. The flow-inoculation system 8 can move synchronously with the bracket assembly 4 to realize the synchronous addition of the inoculant during pouring when the three-dimensional position of the sand box gate is not fixed.

[0061] Example 2

[0062] In another typical embodiment of the present invention, a pouring method is proposed, which adopts the double-side tilting pouring system mentioned in Example 1, as follows:

[0063] A plurality of sand boxes are placed on the two second conveyor rollers 10 respectively by using a hoisting device, and at the same time, a ladle 3 is hoisted onto the two first conveyor rollers 9 respectively by using a hoisting device, so that the pouring ports of the ladle 3 on the two first conveyor rollers 9 face in opposite directions;

[0064] According to the position of the second conveyor roller 10 where the flask 1 to be poured is located, the first conveyor roller 9 on the same side as the second conveyor roller 10 is controlled to start, and the third conveyor roller 11 is started at the same time to convey the ladle 3 to the front of the initial position hanger assembly 4;

[0065] The mobile drive unit at the bottom of the hanger is actuated, so that the hanger assembly 4 is located at one side of the iron ladle 3, and then the moving crossbeam 5 is started and moves toward the direction close to the iron ladle 3, so that the hook 43 on the hanger 42 is located obliquely below the corresponding first hanging point 31, and the mobile drive unit is actuated again, so that the hook 43 is located directly below the corresponding first hanging point 31, that is, the hanger 42 is inserted from one side of the iron ladle 3, and finally the lifting mechanism 6 is started to lift the hanger assembly 4, and then lift the iron ladle 3;

[0066] The movable crossbeam 5 moves toward the direction close to the sand box 1 to be poured, so as to move the lifted molten iron ladle 3 between the two second conveying rollers 10 and to one side of the sand box 1 to be poured. At the same time, the flow inoculation system 8 moves synchronously with the hanger assembly 4, and the servo reduction motor 41 is started to drive the molten iron ladle 3 to tilt through the hanger 42 to carry out the pouring work. During the pouring process, the three-axis moving device can move as needed to meet the pouring requirements, and the inoculant is added synchronously during the pouring.

[0067] The tilting control of the ladle 3 is achieved by the cooperation of the three-axis moving device and the hanger assembly 4. The overall structure is simple, easy to operate, and more flexible. It can meet the casting needs of sand boxes at different positions, enrich the process layout of the casting line, and effectively improve the production efficiency of the casting line.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
