Description

Technical Field

[0001] The invention relates to the technical field of iron casting machines, in particular to an automatic iron knocking mechanism applied to iron casting machines. Background Art

[0002] The iron casting machine is a device that continuously casts iron blocks with molten iron. It is equipped with a circulating chain belt with multiple iron molds and chain plates, which runs around the star-shaped large gears at the upper and lower ends. The upper star-shaped large gear is the driving wheel, driven by the motor, and the lower star-shaped large gear is the driven wheel. Its bearing position can be moved back and forth to adjust the tightness of the chain belt. The working process of the iron casting machine is to let the molten iron in the buffer bag filled with molten iron flow into the cast iron machine mold through the molten iron flow trough. The cast iron machine mold filled with molten iron moves upward at a uniform speed under the drive of the chain belt; during the transportation process, the water spray device sprays cooling water on the crusted iron blocks to accelerate the cooling of the iron blocks; the iron blocks fall off at the head star wheel, and are transported to the finished product workshop for sorting and packaging by the chute into the transport vehicle.

[0003] During the demoulding process of the cast iron machine, due to many factors, there is always a part of the iron block on the casting mold of the cast iron machine that cannot be demoulded normally, resulting in the casting mold sticking to the cast iron block, which reduces the quality of the cast iron block. In order to ensure the smooth demoulding of the iron block, an iron stripping device is usually set on the cast iron machine to assist in demoulding; or slurry is continuously sprayed into the mold of the cast iron machine when the cast iron machine is running. However, although the demoulding efficiency can be improved by the above method, some iron blocks are still not easy to fall off, and the solution is to knock them off manually. In order to achieve the goal of "people-oriented, safe production", all molds need to be demoulded. In view of this, the present invention is designed to provide an automatic iron-making device to improve the demoulding efficiency of the cast iron machine, and on the other hand, it also solves the unsafe factors of personnel. Summary of the invention

[0004] The object of the present invention is to provide an automatic iron knocking mechanism for an iron casting machine, so as to solve the problem in the above background technology that the molds which are not easy to fall off are still knocked off manually.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic iron-beating mechanism applied to an iron casting machine, comprising a load-bearing frame installed at the head of the iron casting machine and a welding frame for installing the automatic iron-beating mechanism, a welding frame is arranged above the load-bearing frame, and a wheel hub is arranged and installed on the upper end of the load-bearing frame, and the wheel hub is installed on the inner ring of the star wheel, and the support frame with the wheel hub facing outward is fixedly connected to the inner wall of the star wheel, a fixed shaft is installed above the welding frame, and the fixed shaft passes through one end surface of the force arm and the load-bearing arm respectively, and a knocking hammer is installed at the end of the load-bearing arm;

[0006] A roller is installed at the outer end of the star wheel, and the roller is engaged and connected with the sprocket of the cast iron machine;

[0007] A toggle wheel is arranged in the axial direction of the star wheel, and the toggle wheel sleeve is installed on the outer side of the hub, the outermost point of the outer side of the toggle wheel coincides with the outermost point of the star wheel, and the overlapping part is penetrated by the shaft of the roller.

[0008] With the above design, the welding frame is directly installed on top of the original load-bearing frame through welding technology, which is convenient for modification and use, and the toggle wheel is symmetrically arranged on the outside of the star wheel, which is convenient for modification. When the star wheel drives the cast iron machine sprocket to transmit, the toggle wheel located on the outside also drives the automatic iron knocking mechanism to rotate.

[0009] Preferably, the upper end of the load-bearing frame is arranged as a frame of an inclined structure, and the inclined frame structure is rotatably connected to the wheel hub through a steel frame, and the inclined frame structure is arranged tangentially to the outer side of the wheel hub through the steel frame.

[0010] With the above design, the inclined structure provides strong support for the wheel hub, keeping the rotating wheel hub stable at all times.

[0011] Preferably, the outer ring of the toggle wheel is arranged with sickle-shaped groove patterns at equal intervals, and the grooves are slidably connected with the end of the force arm, and the toggle wheel is composed of two arc-shaped components.

[0012] With the above design, when the toggle wheel rotates with the star wheel, the texture of the outer ring of the toggle wheel causes the force arm to rotate, thereby the force arm drives the load-bearing arm to rotate, making it easier to swing the load-bearing arm and complete the storage of gravitational potential energy.

[0013] Preferably, the surface of the load-bearing arm is provided with a slide rail with an arc-shaped structure and a positioning hole.

[0014] Preferably, the knocking hammer comprises a knocking rod for transmission and a gravity hammer for hammering and knocking down the mold, wherein the knocking rod is fixedly connected to the fixing rod through a steel spring installed on one side, and a second positioning hole is opened on the surface of the fixing rod;

[0015] A gravity hammer is fixedly mounted on the outer wall of the end of the knocking rod away from the steel spring, and the gravity hammer is mounted toward the star wheel.

[0016] Preferably, two positioning holes 2 are arranged on the surface of the fixing rod, and the positioning hole 2 facing outward is connected to the slide rail through a mounting piece, while the positioning hole 2 facing the steel spring is connected to the positioning hole 1 through a mounting piece.

[0017] With the above design, the hammer is affected by the gravity potential energy of the load-bearing arm, and the hammer performs free fall motion, and finally completes the falling hammer. When the gravity hammer hits the mold, the gravity hammer rebounds under force, and the arc-shaped slide rail plays a role in unloading, preventing the rebound force from being entirely borne by the fixed rod. Similarly, the steel spring plays a role in unloading, and the steel spring makes the vibration effect of the knocking rod stronger and the knocking effect better.

[0018] Preferably, a transmission component is also installed on the outside of the fixed shaft, the transmission component is configured as a symmetrical frame structure, and a fixed wheel is installed inside the transmission component, and the shafts on both sides of the fixed wheel are installed in the inner wall of the transmission component.

[0019] With the above design, the transmission component is also affected by the load-bearing arm, and the transmission component falls on the surface of the mold, achieving pre-tapping and a good tapping effect.

[0020] Preferably, a screw hole is provided inside the fixing wheel, and the axis of the screw hole is perpendicular to the axis of the fixing wheel. At the same time, a screw rod is inserted through the screw hole, and the other end of the screw rod is installed through the inside of the mounting seat.

[0021] Preferably, a screw hole for the screw rod to pass through is also provided inside the mounting seat, and the axis of the mounting seat is perpendicular to the axis of the screw hole inside the mounting seat. The mounting seat is installed on the outside of the force arm, and the mounting seat and the force arm are installed through a fixing piece.

[0022] By adopting the above technology, the position of the nut on the surface of the screw is adjusted, and the position of the fixed wheel is adjusted, thereby changing the distance between the transmission component and the force arm, thereby changing the landing point of the transmission component.

[0023] Compared with the prior art, the invention has the following beneficial effects: the automatic iron knocking mechanism applied to the cast iron machine:

[0024] 1. The overall erection of the knocking structure is installed above the welding frame, which is convenient for modification on the cast iron machine. The toggle wheel is installed on the outside of the star wheel. When the star wheel rotates, it can drive the toggle wheel to rotate at the same speed. The circumferential track on the outer wall of the toggle wheel drives the power arm to rotate, thereby completing the knocking action of the knocking hammer and realizing the knocking of the mold. The whole process does not require manual operation, and the knocking effect can be achieved by using the transmission system of the cast iron machine itself. The modification process is simple;

[0025] 2. The force arm is fixedly connected with the transmission component and the percussion hammer at the same time, so the force arm drives the transmission component and the percussion hammer to knock the mold driven on the outer side of the star wheel at the same time. The transmission component is located in front of the percussion hammer, so the transmission component falls on the outer side of the mold to knock first, which has a pre-tapping effect, so as to improve the knocking success rate of the percussion hammer;

[0026] 3. The percussion hammer includes a gravity hammer and a steel spring. The steel spring has a good buffering effect, which makes the vibration effect of the gravity hammer better, and reduces the recoil force of the percussion transmitted to the load-bearing arm, thereby improving the stability of the load-bearing arm.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-10 The present invention provides a technical solution: an automatic iron-beating mechanism applied to a cast iron machine, wherein a welding frame 2 is arranged above a load-bearing frame 1, and a wheel hub 3 is mounted on the upper end of the load-bearing frame 1, the upper end of the load-bearing frame 1 is arranged as a frame of an inclined structure, and the inclined frame structure is rotatably connected to the wheel hub 3 through a steel frame, and at the same time, the inclined frame structure is tangent to the outer side of the wheel hub 3 through the steel frame. First, the welding frame 2 is installed on the load-bearing frame 1 of the cast iron machine head. When the wheel hub 3 is driven by a driving member for installation, the wheel hub 3 drives the star wheel 4 to rotate, and then the star wheel 4 drives the toggle wheel 15 to rotate, and the toggle wheel 15 makes the entire striking mechanism move.

[0043] The initial state of the hammer 8 is as follows: Figure 3 As shown, when the toggle wheel 15 rotates, the sickle-shaped outer ring on the outside rotates. Since the end of the force arm 6 is stuck inside the toggle wheel 15, the toggle wheel 15 rotates clockwise to drive the force arm 6 to rotate, and the force arm 6 rotates counterclockwise about the center of the fixed shaft 5, that is, the load-bearing arm 7 and the transmission member 9 rotate counterclockwise with the force arm 6, the load-bearing arm 7 drives the percussion hammer 8 to rise, and the percussion hammer 8 drives the gravity hammer 84 to rise;

[0044] Until the roller 14 passes over the lower end of the lever arm 6, the hammer 8 is struck as Figure 4 As shown, the gravity hammer 84 is at the top of the motion trajectory. Under the action of the gravity of the hammer 8, the hammer 8 drives the slide rail 71 to fall naturally, and the hammer 8 falls on the mold outside the sprocket of the cast iron machine.

[0045] When the transmission component 9 also rotates with the fixed shaft 5, when it falls, the transmission component 9 will first fall on the mold outside the cast iron machine sprocket, and the long shaft installed in the center of the transmission component 9 falls, which has a knocking effect on the mold. As the star wheel 4 rotates clockwise, the mold that has been knocked in advance is knocked again by the knocking hammer 8, thereby improving the knocking effect.

[0046] The hub 3 is installed on the inner ring of the star wheel 4, and the support frame of the hub 3 facing outward is fixedly connected to the inner wall of the star wheel 4. A fixed shaft 5 is installed above the welding frame 2, and the fixed shaft 5 passes through the surface of one end of the force arm 6 and the load-bearing arm 7 respectively. A percussion hammer 8 is installed at the end of the load-bearing arm 7. The surface of the load-bearing arm 7 is provided with an arc-shaped slide rail 71 and a positioning hole 72;

[0047] A roller 14 is installed at the outer end of the star wheel 4, and the roller 14 is engaged with the sprocket of the cast iron machine.

[0048] The star wheel 4 is provided with a toggle wheel 15 in the axial direction, and the toggle wheel 15 is sleeved and installed on the outside of the wheel hub 3. The outermost point of the outer side of the toggle wheel 15 coincides with the outermost point of the star wheel 4, and the overlapped part is penetrated and installed by the shaft of the roller 14. The outer ring of the toggle wheel 15 is evenly spaced to form sickle-shaped groove patterns, and the groove forms a sliding connection with the end of the lever arm 6. The toggle wheel 15 is composed of two arc components. When the automatic iron knocking mechanism is prefabricated, the arc components are installed and welded according to the design size. When installing, remove the gear bolts on any half of the star wheel 4 of the cast iron machine, install the transmission wheel, and after the first arc component is installed, install another one in the same way, so that the toggle wheel 15 is located directly below the lever arm 6.

[0049] The knocking hammer 8 includes a knocking rod 81 for transmission and a gravity hammer 84 for knocking down the mold, wherein the knocking rod 81 is fixedly connected to a fixing rod 83 through a steel spring 82 installed on one side, and a second positioning hole 85 is opened on the surface of the fixing rod 83;

[0050] A gravity hammer 84 is fixedly mounted on the outer wall of the end of the knock rod 81 away from the steel spring 82 , and the gravity hammer 84 is mounted toward the star wheel 4 .

[0051] In this embodiment, two striking hammers 8 are symmetrically arranged on the outer side of the fixed shaft 5, and the striking rods 81 of the two groups of striking hammers 8 are set with different lengths, which is convenient for striking the molds at different locations to achieve mold resonance.

[0052] Two second positioning holes 85 are provided on the surface of the fixing rod 83 , and the second positioning hole 85 facing outward is connected to the slide rail 71 through a mounting member, while the second positioning hole 85 facing the steel spring 82 is connected to the first positioning hole 72 through a mounting member.

[0053] When the fixed rod 83 is raised or lowered, Figure 5-6 As shown, the second positioning hole 85 on the right side of the surface of the fixed rod 83 is rotatably connected to the positioning hole 1 72 through a pin, and the second positioning hole 85 on the left side of the surface of the fixed rod 83 is also connected to the slide rail 71 through a pin. Therefore, when the fixed rod 83 and the load-bearing arm 7 rotate relative to each other, the second positioning hole 85 on the left side of the surface of the fixed rod 83 and the slide rail 71 are relatively offset, ensuring the stable rotation of the load-bearing arm 7 and the fixed rod 83.

[0054] And when the fixed rod 83 rotates in the air, the steel spring 82 drives the fixed rod 83 to rotate, so that the fixed rod 83 has a large rotation range. After that, after the gravity hammer 84 falls on the mold surface to knock, the steel spring 82 drives the gravity hammer 84 to rebound, so that the knocking effect is good, and the action path simulates the action of human knocking.

[0055] A transmission member 9 is also installed on the outside of the fixed shaft 5, and the transmission member 9 is set as a symmetrical frame structure, and a fixed wheel 11 is installed inside the transmission member 9, and the shafts on both sides of the fixed wheel 11 are installed in the inner wall of the transmission member 9. And the center of the fixed wheel 11 is penetrated by a long shaft, and the long shaft plays a role of falling and knocking.

[0056] A screw hole 13 is provided inside the fixing wheel 11 , and the axis of the screw hole 13 is perpendicular to the axis of the fixing wheel 11 . Meanwhile, a screw rod 10 is inserted through the screw hole 13 , and the other end of the screw rod 10 is installed through the inside of the mounting seat 12 .

[0057] The mounting seat 12 is also provided with a screw hole 13 for the screw rod 10 to pass through, and the axis of the mounting seat 12 is perpendicular to the axis of the screw hole 13 inside it. The mounting seat 12 is installed on the outside of the lever arm 6, and the mounting seat 12 and the lever arm 6 are installed by a fixing piece.

[0058] refer to Figure 7-8 The position of the fixed wheel 11 can be adjusted by turning the screw 10. When the fixed wheel 11 moves to the right, the fixed wheel 11 moves to the right on the outside of the screw 10, increasing the distance between the fixed wheel 11 and the lever arm 6, thereby changing the position where the transmission member 9 falls, so that the point where the transmission member 9 falls coincides with the gravity hammer 84.

[0059] Working principle: When using the automatic iron knocking mechanism applied to the cast iron machine, the knocking mechanism can be installed on the head of the cast iron machine by setting a welding frame 2 above the load-bearing frame 1. The driving motor of the head part of the cast iron machine is rotated, which can simultaneously drive the star wheel 4 and the toggle wheel 15 to rotate. The star wheel 4 drives the entire mold transmission cooling mechanism of the cast iron machine to rotate, and the toggle wheel 15 drives the knocking mechanism in this embodiment to rotate, and the knocking mechanism is divided into a knocking hammer 8 and a transmission component 9. The transmission component 9 performs the first knocking, and the knocking hammer 8 performs the second knocking, thereby improving the knocking efficiency.

[0060] In addition, in this implementation, reference Fig. 9 The fixed shaft 5 is fixedly installed above the welding frame 2, and the force arm 6 is rotatably installed on the surface of the fixed shaft 5, so that the force arm 6 can rotate outside the fixed shaft 5, and the fixed shaft 5 is rotatably connected with the load-bearing arm 7 and the transmission member 9, and the fixed wheel 11 is located on the outside of the star wheel 4. At the same time, a long shaft is installed at the center of the fixed wheel 11. The long shaft falls with the fixed wheel 11 and falls on the outside of the mold to achieve knocking.

[0061] The toggle wheel 15 is installed on both sides of the star wheel 4, and the knocking hammer 8 is installed on the side of the load-bearing arm 7, so that the knocking hammer 8 and the transmission component 9 just fall on the top of the star wheel 4 to accurately knock the transported mold.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
