Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a pouring machine with a double plug rod pouring mechanism. Background Art

[0002] In the casting process, a pouring machine is usually required to inject the molten metal into the mold for casting. In the pouring process, the plug rod mechanism is a very important component, which can control the flow rate and flow speed of the molten metal, thereby ensuring the quality and performance of the casting.

[0003] In the prior art, a Chinese patent with a patent publication number of CN106955995A discloses an adjustable plug rod mechanism control device, including a box, a pneumatic control box, an electric cylinder assembly, a cantilever assembly, a plug rod clamp assembly and a plug rod. The electric cylinder assembly is arranged in the box and passes through the top of the box upward. The fixed end of the cantilever assembly is connected to the top of the electric cylinder assembly and the movable end is connected to the plug rod clamp assembly. The plug rod is arranged on the plug rod clamp assembly. In addition, a lower bearing, an eccentric flange, an upper bearing and a pneumatic brake are arranged between the fixed end of the cantilever assembly and the electric cylinder assembly. The bottom surface of the eccentric flange is mounted on the top of the electric cylinder assembly through the lower bearing. The fixed end of the cantilever assembly is mounted on the eccentric flange through the upper bearing. The pneumatic brake is arranged on the top of the electric cylinder assembly and is used to clamp the cantilever assembly, so that the horizontal distance between the center of the upper bearing and the central axis of the plug rod is a fixed value, and the horizontal distance between the center of the lower bearing and the central axis of the plug rod is adjustable, that is, the horizontal position of the plug rod is adjustable. The adjustment process is as follows: Figure 1 As shown, the initial horizontal distance between the center of the upper bearing 73 and the central axis of the plug rod 6 is L1. When adjustment is required, the brake 74 first releases the cantilever assembly 4, and then controls the eccentric flange 72 and the upper bearing 73 to rotate around the central axis of the lower bearing 71, so that the upper bearing 73 revolves around the central axis of the lower bearing 71, and then controls the upper bearing 73 to rotate around the eccentric axis of the eccentric flange 72, so that the upper bearing 73 rotates around the eccentric axis of the eccentric flange 72, and finally the horizontal distance between the center of the upper bearing 73 and the central axis of the plug rod 6 becomes L2, so that the horizontal position of the plug rod 6 can be adjusted. When using the above-mentioned adjustable plug rod mechanism control device, by adjusting the horizontal position of the plug rod 6, the position error caused by the inaccurate installation of the ladle device can be compensated.

[0004] Although the above-mentioned prior art can meet the basic demand for adjusting the horizontal position of the plug rod, in the process of controlling the rotation of the upper bearing, it is still necessary to manually move the cantilever assembly to operate, which has the defect of being difficult to accurately adjust the horizontal position of the plug rod, and a single plug rod is used for casting, and the production efficiency is low. Utility Model Content

[0028] The following will be combined with the attached Figure 2 -Attached Figure 4 The utility model is further described with examples.

[0029] This embodiment discloses a pouring machine with a double plug rod pouring mechanism.

[0030] Reference Figure 2 The pouring machine includes a bottom plate 11, a supporting structure 15 and a plug rod structure. A support platform 12 is provided on the top of the bottom plate 11. A placement slot 13 is provided on the top of the support platform 12. The supporting structure 15 is movably arranged on the bottom plate 11 through a lifting cylinder, or is used on a robotic arm. A mold 14 is placed on the top of the supporting structure 15. The mold 14 is movably engaged in the placement slot 13. The plug rod structure is provided with two groups, which are respectively located on both sides of the mold 14. The plug rod structures are connected to the top of the support platform 12. Figure 3 and Figure 4, the plug rod mechanism includes a box body 1, a control box 2, an electric cylinder assembly, a cantilever assembly 4, a plug rod clamp assembly 5 and a plug rod 6. Among them, both control boxes 2 are connected to the top of the support platform 12, the control box 2 is arranged outside the box body 1, the electric cylinder assembly is arranged in the box body 1 and penetrates the top of the box body 1 upward, and a lifting plate 3 is arranged at the upper end of the electric cylinder assembly, and the electric cylinder assembly controls the lifting plate 3 to lift and lower. The cantilever assembly 4 includes a fixed end and a movable end, the fixed end of the cantilever assembly 4 is connected to the lifting plate 3 on the top of the electric cylinder assembly and the movable end is connected to the plug rod clamp assembly 5, the plug rod 6 is arranged on the plug rod clamp assembly 5, and the outlet end of the plug rod 6 extends to the inside of the mold 14, wherein the casting method adopts a double plug rod and a double control system, which can speed up the casting speed, improve production efficiency, and can control the corresponding plug rod 6 individually to adapt to the subtle differences in different working conditions during the double casting process. A lower bearing 71, an eccentric flange 72, an upper bearing 73 and a brake 74 are arranged between the fixed end of the cantilever assembly 4 and the lifting plate 3 of the electric cylinder assembly. The bottom surface of the eccentric flange 72 is installed on the top of the electric cylinder assembly through the lower bearing 71, and the fixed end of the cantilever assembly 4 is installed on the eccentric flange 72 through the upper bearing 73, so that the horizontal distance between the center of the upper bearing 73 and the central axis of the plug rod 6 is a fixed value, and the horizontal distance between the center of the lower bearing 71 and the central axis of the plug rod 6 is adjustable, that is, the horizontal position of the plug rod 6 is adjustable.

[0031] The eccentric flange 72 is provided with a worm 81, and the upper bearing 73 is provided with a worm wheel 82. The worm 81 is meshed with the worm wheel 82, so that when the worm 81 rotates, the worm wheel 82 is driven to rotate, thereby driving the upper bearing 73 to rotate around the eccentric axis of the eccentric flange 72, and finally driving the cantilever assembly 4 to rotate. Through this arrangement, on the one hand, the worm 81 can act as a handle, which is convenient for the staff to control the rotation of the eccentric flange 72 around the central axis of the lower bearing 71. On the other hand, after the rotation of the eccentric flange 72 is completed, the upper bearing 73 can be directly controlled to rotate by rotating the worm 81, so as to achieve the effect of conveniently controlling the rotation of the upper bearing 73. Compared with the prior art that uses the method of manually bending the cantilever assembly 4 to operate the rotation of the upper bearing 73, the utility model can achieve precise control of the rotation of the upper bearing 73 through the cooperation of the worm wheel 82 and the worm 81, thereby achieving precise control of the rotation of the cantilever assembly 4, and finally achieving the effect of accurately adjusting the horizontal position of the plug rod 6.

[0032] In order to realize the installation of the worm 81 on the eccentric flange 72, a first mounting frame 91 is provided on one side of the circumference of the eccentric flange 72. The first mounting frame 91 is concave, and the two ends of the worm 81 are respectively rotatably connected to the two ends of the first mounting frame 91. In addition, in order to facilitate the staff to use the worm 81 to control the rotation of the eccentric flange 72 and the upper bearing 73, a screw block 811 is provided at the end of the worm 81. When the worm 81 acts as a handle, the staff can hold the screw block 811 to rotate the eccentric flange 72. When the worm 81 is required to drive the worm wheel 82 to rotate so as to rotate the upper bearing 73, the staff can screw the screw block 811 at the end of the worm 81. Further, the screw blocks 811 are provided at both ends of the worm 81, so that the staff can conveniently operate on both sides of the worm 81. In addition, the screw block 811 is also provided with anti-skid patterns to improve the anti-skid effect of the screw block 811 and facilitate the staff to operate.

[0033] In the prior art, since the brake 74 is fixedly arranged on the top of the electric cylinder assembly, the brake 74 fixes the position of the cantilever assembly 4 after adjustment by clamping it. Therefore, the brake 74 can only be used to clamp the eccentric flange 72 and the upper bearing 73 after they have completed rotation in sequence. This causes the upper bearing 73 to still have the possibility of orbiting around the central axis of the lower bearing 71 when rotating around the eccentric axis of the eccentric flange 72, and ultimately causes the plug rod 6 to fail to adjust to the expected position. In addition, since the brake 74 in the prior art is fixed on the top of the electric cylinder assembly, the brake 74 is on the rotation path of the cantilever assembly 4, so that the brake 74 will limit the rotation range of the cantilever assembly 4. To this end, the utility model further makes the following improvements.

[0034] The brake 74 is mounted on the eccentric flange 72 and rotates synchronously with the rotation of the eccentric flange 72. A fixing ring 31 is mounted on the lifting plate 3 at the top of the electric cylinder assembly. The axis of the fixing ring 31 is colinear with the axis of the lower bearing 71. The rotation path of the brake 74 coincides with the fixing ring 31. The brake 74 is used to hold the fixing ring 31. Through the above arrangement, after the rotation of the eccentric flange 72 is completed, the fixing ring 31 can be directly held by the brake 74 to fix the position of the eccentric flange. Only then can the upper bearing 73 be rotated by the worm 81 and the worm wheel 82, and then the upper bearing 73 is locked by the self-locking effect between the worm 81 and the worm wheel 82. In this process, since the eccentric flange 72 is fixed first and then the upper bearing 73 is rotated, there is no possibility that the upper bearing 73 will still revolve around the central axis of the lower bearing 71 while rotating around the eccentric axis of the eccentric flange 72, ensuring that the plug rod 6 can be adjusted to the expected position. Furthermore, since the brake 74 rotates with the eccentric flange 72, the brake 74 is no longer on the rotation path of the cantilever assembly 4, so that the brake 74 no longer limits the rotation range of the cantilever assembly 4, so that the cantilever assembly 4 can rotate at will. It should be noted that the brake 74 can be a manual brake 74, an electric brake 74, or a pneumatic brake 74, as long as the brake 74 effect can be achieved. In addition, in order to realize the installation of the brake 74 on the eccentric flange 72, a second mounting frame 92 is provided on one side of the circumference of the eccentric flange 72, and the second mounting frame 92 is L-shaped, and the brake 74 is fixedly arranged on the second mounting frame 92.

[0035] In order to install the fixing ring 31 on the lifting plate 3 , four mounting blocks 32 are provided inside the fixing ring 31 , and the four mounting blocks 32 are respectively fixed on the lifting plate 3 , so as to facilitate replacement or maintenance of the fixing ring 31 .

[0036] The first mounting frame 91 and the second mounting frame 92 are arranged on the outer side of the circumference of the eccentric flange 72 away from each other, ensuring that the worm 81 and the brake 74 have sufficient operating space, and the first mounting frame 91 and the second mounting frame 92 are detachably mounted on the eccentric flange 72 by screws, so that the worm 81 and the brake 74 can be easily removed for replacement or maintenance. Further, the matching position of the worm 81 and the worm wheel 82 is at the tangent position of the upper bearing 73 and the eccentric flange 72, so that the size of the worm 81 and the worm wheel 82 does not need to be too large.

[0037] In order to further improve the self-locking effect of the worm 81 and the worm wheel 82 on the upper bearing 73, rotation dampers 911 are provided at both ends of the first mounting frame 91. The two ends of the worm 81 are rotatably connected to the two ends of the first mounting frame 91 through the two rotation dampers 911. By providing the rotation dampers 911, the worm 81 is prevented from self-rotating easily without operation, so as to improve the self-locking effect of the worm 81 and the worm wheel 82 on the upper bearing 73. In other embodiments, the friction of the rotation of the worm 81 can also be improved by means of gaskets, etc., to achieve the same effect.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
