Description

Technical Field

[0001] The utility model belongs to the technical field of smelting and spheroidizing treatment, and mainly relates to a simple material adding device. Background Art

[0002] Smelting spheroidization is a metal processing technology mainly used to improve the properties of metal materials, especially in cast iron production. The basic process of spheroidization is to melt the cast iron and add a spheroidizing agent. These spheroidizing agents react with sulfides and silicon oxides in the molten iron to form compounds such as magnesium sulfide or cerium sulfide. These compounds form cores in the molten iron, causing graphite to precipitate in the form of spheres instead of flakes or prisms.

[0003] During smelting and spheroidizing operations, magnesium blocks are usually used. The magnesium blocks are added to the magnesium block material box, and then the material box with magnesium blocks is added to the molten iron. However, when adding magnesium blocks to the magnesium gun material box, it is necessary to put the magnesium blocks on the tray, hold the tray with one hand, and insert the pin into the socket on the material box with the other hand to fix the tray, that is, fix the magnesium blocks. This operation is difficult, requires a lot of physical strength, and the efficiency of adding magnesium blocks is low. When pressure magnesium is added for continuous production, the magnesium adding gun is in a red-hot state, the working environment temperature is high, and the physical strength of the personnel is quickly consumed. Utility Model Content

[0004] The utility model provides a simple material adding device to solve the problem of high labor intensity when adding magnesium blocks in the prior art.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] A simple material adding device comprises a tray for placing magnesium blocks, a first driving member, a fixing mechanism and a mounting seat; the fixing mechanism is rotatably assembled on the mounting seat, a second driving member is provided on the mounting seat, and a transmission mechanism for driving the fixing mechanism to rotate is transmission-connected between the second driving member and the fixing mechanism; the first driving member is relatively fixed to the fixing mechanism, and a driving end of the second driving member is connected to the tray to drive the tray to rise and fall.

[0007] Beneficial effect: The first driving member pushes the tray with magnesium blocks into the material box, and it is no longer necessary to hold the tray manually. Instead, the tray can be fixed by inserting a pin into the fixing hole on the material box, thereby realizing semi-automatic addition of magnesium blocks, saving manpower, and improving work efficiency. However, considering the impact on other production activities, after the addition of magnesium blocks is completed, the second driving member drives the fixing mechanism and the first driving member to rotate to a position that does not hinder other production activities. The structure is simple, practical, flexible, and easy to operate.

[0008] Further, the fixing mechanism includes vertical plates on the left and right sides of the first driving member, a bottom plate fixedly connected to the lower ends of the vertical plates, a fixing plate detachably connected to the tops of the two vertical plates, and a central shaft connected at the connection position between the vertical plates and the bottom plate. The first driving member is placed on the bottom plate, the fixing plate is press-fitted on the first driving member, and the central shaft extends in the left-right direction and is rotationally assembled with the mounting seat.

[0009] Beneficial effects: The fixing plate is detachably press-fitted on the first driving member. When the first driving member is damaged, it can be disassembled and repaired.

[0010] Further, the mounting seat is provided with a rotation groove adapted to the central shaft, and the central shaft is rotationally assembled in the rotation groove; the transmission mechanism includes transmission gears coaxially fixed at both ends of the central shaft, and transmission racks slidably assembled on the mounting seat in the front-rear direction and meshing with the corresponding transmission gears. The second driving members correspond to the transmission racks one by one. The second driving members are linear driving members, and the driving ends are connected to the corresponding fixed transmission racks.

[0011] Beneficial effects: The central shaft is rotationally assembled in the rotation groove to ensure the stability of the fixing mechanism during rotation; the gear-rack transmission can achieve precise linear motion because the teeth on the rack are meshed with the teeth of the gear, and the moving distance of each tooth is fixed, thus ensuring the accuracy of the motion.

[0012] Further, the mounting seat is also provided with chutes corresponding to the transmission racks one by one, and the transmission racks are slidably assembled in the chutes.

[0013] Beneficial effects: The chutes provide a precise linear motion path for the racks, ensuring the linearity and stability of the motion. The cooperation between the racks and the chutes can also effectively maintain the motion accuracy because the chutes limit the lateral movement of the racks, reducing deviation and vibration.

[0014] Further, the mounting seat includes a seat body and limiting plates mounted on the seat body and symmetric about the first driving member on the left and right. A guiding rod extending in the left-right direction is also connected between the two vertical plates. The guiding rod is parallel to the central shaft. Arc-shaped limiting holes are respectively provided on the two limiting plates. The two ends of the guiding rod respectively pass through the two arc-shaped limiting holes and are slidably matched with the arc-shaped limiting holes.

[0015] Beneficial effects: The guiding rod slides in the arc-shaped limiting holes, further enhancing the stability of the fixing mechanism during rotation and ensuring the accuracy of the rotation direction.

[0016] Further, two support legs corresponding to the vertical plates one by one for supporting the fixing mechanism are provided on the front side of the seat body, and the support legs are fixedly connected to both the seat body and the second driving member.

[0017] Beneficial effects: When the fixing mechanism rotates to the state where the vertical plate is horizontal, the vertical plate fits against the support leg. At this time, with the guide rod as the support point, the support leg plays a supporting role for the fixing mechanism, preventing the weight at the front end of the fixing mechanism relative to the guide rod from tilting up the rear end of the fixing mechanism.

[0018] Further, both the first driving member and the second driving member are hydraulic cylinders.

[0019] Beneficial effects: The hydraulic system can provide greater force than electrical or pneumatic systems, which is beneficial for applying a greater force to the transmission gear to ensure the stable rotation of the fixing mechanism. The hydraulic system can precisely control the displacement and speed of the hydraulic cylinder by adjusting the flow rate and pressure, thereby achieving precise motion control. Moreover, due to its hydrodynamic characteristics, the hydraulic system can provide a very smooth and stable motion, and can maintain the stable rotation of the fixing mechanism when rotating the fixing mechanism.

[0020] Further, the arc-shaped limiting hole is a quarter-circular hole.

[0021] Beneficial effects: The arc-shaped limiting hole is a quarter-circular hole. When the fixing mechanism rotates to the state where the vertical plate fits against the support leg, the guide rod simultaneously reaches the other end of the arc-shaped limiting hole, ensuring the accuracy of the rotation angle of the fixing mechanism.

The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction without any limiting meaning. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0029] Embodiment 1 of a simple material adding device provided by the present invention:

[0030] As Figure 1 shown, a simple material adding device includes a first driving member, a second driving member, a mounting base, a fixing mechanism, and a tray 5 that can move up and down.

[0031] As Figure 1 shown, the first driving member is a first hydraulic cylinder 8. The cylinder body of the first hydraulic cylinder 8 is located on the mounting base. A sleeve 3 is connected to the lower end of the tray 5. The first hydraulic cylinder 8 is self-equipped with a first piston rod 6. Corresponding sockets are provided on the sleeve 3 and the first piston rod 6. The two are fixed by inserting a pin into the socket, and the two can be disassembled by pulling out the pin, thereby realizing the detachable assembly of the sleeve 3 and the first piston rod 6. The material box 1 is suspended in the air. The material box 1 is provided with a downward opening. The planar size of the tray 5 is the same as the size of the downward opening of the material box 1, and the position of the material box 1 is consistent with the position of the tray 5 in the vertical direction.

[0032] As Figure 1 and Figure 2 shown, the fixing mechanism includes a fixing plate 4, vertical plates 9 symmetrically arranged on the left and right sides of the first hydraulic cylinder 8, and a bottom plate 10 fixedly connected to the lower ends of the vertical plates 9. The fixing plate 4 presses on the upper ends of the two vertical plates 9 and the cylinder body of the first hydraulic cylinder 8 and is connected to the two vertical plates 9 by fastening bolts 7. The first hydraulic cylinder 8 is placed on the bottom plate 10, and the relative fixation with the bottom plate 10 is achieved by relying on the pressing force of the fixing plate 4. By adjusting the fastening bolts 7, the fixing plate 4 presses the cylinder body of the first hydraulic cylinder 8 to ensure that when the first piston rod 6 moves, the cylinder body of the first hydraulic cylinder 8 remains stable and does not shift.

[0033] As Figure 1 and Figure 2As shown in the figure, the mounting base includes a limiting plate 12 and a base body 14. The base body 14 is provided with sliding grooves 23 arranged in parallel at intervals from left to right, and the sliding grooves 23 extend in the front-rear direction. The bottom plate 10 is located on the base body 14, and the axis of the first piston rod 6 is located on the symmetry center line of the left and right ends of the base body 14. The base body 14 is provided with a rotating groove extending in the left-right direction. A central shaft 13 is rotatably arranged in the rotating groove. The central shaft 13 is rotationally assembled with the rotating groove, and the central shaft 13 is fixedly connected to both vertical plates and the bottom plate, so that the vertical plates and the bottom plate can rotate together with the central shaft. Two transmission gears 17 are coaxially and fixedly connected to both ends of the central shaft 13. A guide rod 11 is fixedly connected to the front side of the two vertical plates 9 and near the upper ports of the vertical plates 9. The guide rod 11 is parallel to the central shaft 13.

[0034] As Figure 1 and Figure 2 shown in the figure, there are two limiting plates 12. The two limiting plates 12 are symmetrically arranged on the base body 14 about the first hydraulic cylinder 8 from left to right. The limiting plates 12 are provided with arc-shaped limiting holes 16 centered on the axis of the central shaft 13. Both ends of the guide rod 11 are respectively inserted into the two arc-shaped limiting holes 16 and can slide along the arc-shaped limiting holes 16. The arc-shaped limiting holes 16 are quarter-circular holes, which can enable the guide rod 11 to slide from the upper end of the arc-shaped limiting hole 16 to the lower end of the arc-shaped limiting hole 16. The base body 14 is provided with a support groove 15 adapted to the guide rod 11. The support groove 15 is parallel to the axis of the rotating groove in the horizontal direction. When the guide rod 11 rotates to the lower end of the arc-shaped limiting hole 16, the guide rod 11 can enter the support groove 15. The central shaft 13, the guide rod 11, the vertical plates 9, the bottom plate 10, the first hydraulic cylinder 8 and the fixing plate 4 form an integral body to rotate as a whole when the central shaft 13 rotates in the rotating groove.

[0035] As Figure 2 shown in the figure, the sliding grooves 23 are located inside the corresponding limiting plates 12. A transmission rack 22 slidably engaged with the sliding grooves 23 is arranged in each sliding groove 23. The transmission rack 22 is engaged with the corresponding transmission gear 17 on the same side. The transmission rack 22 slides in the sliding groove 23 to drive the transmission gear 17 to rotate, so as to realize the rotation of the above-mentioned integral body.

[0036] As Figure 1 and Figure 2As shown in the figure, the front side of the seat body 14 is fixedly connected with a support frame 18 corresponding to the driving rack 22 one by one in the front and back directions. The second driving member is a second hydraulic cylinder 20. The second hydraulic cylinder 20 is fixedly connected to the corresponding support frame 18. The second hydraulic cylinder 20 is equipped with a second piston rod 21 by itself. The second piston rod 21 is fixedly connected to the front end of the driving rack 22. The axis of the second piston rod 21 is perpendicular to the axis of the central shaft 13 in the horizontal direction. A locking plate 24 is further provided on the mounting seat outside the limiting plate 12. The locking plate 24 is provided with corresponding locking holes 25. The entire mounting seat is fixed to the ground by inserting a locking bolt into the locking hole 25 and then into the locking hole on the ground. Two support legs 19 for supporting the fixing mechanism are fixedly connected to the front side of the seat body 14. The two support legs 19 respectively correspond to the corresponding vertical plates 9 one by one, and the two support legs 19 are respectively fixedly connected to the support frame 18 at the corresponding ends. When the guide rod 11 rotates to the lower end of the arc-shaped limiting hole 16, the vertical plate 9 fits onto the seat body 14. At this time, the guide rod 11 is the main support point, the vertical plate 9 fits on the upper surface of the corresponding support leg 19, and the support leg 19 plays a further supporting role for the above-mentioned whole, preventing the weight of the front end of the above-mentioned whole located at the front end of the guide rod 11 from lifting the rear end of the above-mentioned whole.

[0037] As Figure 1 shown, the first hydraulic cylinder 8 and the second hydraulic cylinder 20 are respectively connected with a first switch and a second switch. The start and stop of the first hydraulic cylinder 8 and the second hydraulic cylinder 20 are controlled by controlling the first switch and the second switch.

[0038] The working process of the present utility model is as follows:

[0039] The cylinder body of the first hydraulic cylinder 8 is fastened to the bottom plate 10 by adjusting the fastening bolts 7 on the fixing plate 4 and the vertical plate 9. The fixing plate 4 presses on the upper end of the cylinder body of the first hydraulic cylinder 8 to complete the fixing of the first hydraulic cylinder 8. The pin is inserted into the socket on the sleeve 3 and the first piston rod 6 to fix the first piston rod 6 and the tray 5. The magnesium block 2 is placed on the tray 5. The first switch is turned on, and the first piston rod 6 drives the tray 5 to move in the direction of the material box 1. When the tray 5 moves into the material box 1, the prepared pin is manually inserted into the corresponding sockets on the material box 1 and the tray 5 to fix the tray 5. The pin on the sleeve 3 is pulled out, the first piston rod 6 moves down to the lowest point, and then the second switch is turned on. The second piston rod 21 pushes the driving rack 22 to move, the driving rack 22 drives the corresponding driving gear 17 to rotate, and the above-mentioned whole rotates. When the guide rod 11 rotates to the lower end of the arc-shaped limiting hole 16, the second switch is turned off.

[0040] The first piston rod 6 pushes the tray 5 with the magnesium blocks 2 into the material box 1. There is no need for manual support of the tray 5 anymore. Only need to manually insert a bolt into the socket on the material box 1 to fix the tray 5, realizing the semi-automatic addition of the magnesium blocks 2, saving manpower and improving work efficiency. When the addition of the magnesium blocks 2 is completed, since there are other production mechanisms moving between the material box 1 and the limit plate 12, the above-mentioned whole is rotated to the position at the lower end of the arc-shaped limit hole 16. At this time, the vertical plate 9 and the first hydraulic cylinder 8 do not hinder the movement of other production mechanisms, ensuring the normal operation of other production mechanisms.
