Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casting processing, in particular to a rotary casting forming equipment and method for casting processing. BACKGROUND

[0002] Casting forming is to pour molten metal, concrete, etc. into a mold for casting of metal parts or forming of cement boards and concrete buildings. However, manual operation is mostly used in the casting forming process, and there is a lack of automatic equipment.

[0003] As disclosed in patent No. CN108655382A, a large amount of liquid in a molten state to be cast is loaded into a containing assembly. The liquid in the containing assembly is stirred and mixed by driving assembly and linkage assembly. Then, a plurality of forming assemblies are successively conveyed to the containing assembly below the conveying table. The liquid in a molten state is poured into each forming assembly in the containing assembly. After the forming assembly cools down, the product is formed and taken out, and the casting operation is completed.

[0004] However, the above patent does not consider the amount of liquid in a molten state in the containing assembly, which cannot accurately control the quality of the liquid in a molten state discharged each time, and easily leads to an increase in the rejection rate of castings formed by casting.

[0005] Therefore, we propose a rotary casting forming equipment and method for casting processing. SUMMARY

[0006] The present application aims to provide a rotary casting forming equipment and method for casting processing to solve the problems in the background art.

[0008] The top of the placing table two is movably connected with a rotating plate, the top of the rotating plate is symmetrically fixed with a placing rack through bolts, the placing rack is movably connected with a ladle, the outer wall of the ladle on one side is installed with a transmission gear, the outer wall of the placing rack and located at the bottom of the transmission gear is fixedly connected with a transmission shell one, the transmission shell one is slidably connected with a toothed plate, one side of the toothed plate is meshingly connected with the transmission gear, and the transmission shell one and located on one side of the toothed plate is slidably connected with a stop block.

[0009] Further, the top of the rotating plate is fixed with a transmission shell two through bolts, the transmission shell two is rotationally connected with a pressing rod, one end of the pressing rod penetrates the transmission shell two and the placing rack and abuts against the bottom of the stopper in the transmission shell one.

[0010] Further, the transmission shell two is slidingly connected with a clamping column on the pressing rod, one end of the clamping column penetrates the transmission shell two and extends to the bottom of the placing rack, the outer wall of one side of the placing rack is fixed with an electric push rod through bolts, the inner wall of the placing rack is slidingly connected with a limiting plate, and one side of the limiting plate is connected with the side of the electric push rod.

[0011] Further, the top of the placing table one is slidingly connected with a jacking mechanism, the jacking mechanism comprises a sleeve, an arc-shaped clamping plate and a threaded jacking rod, the top of the placing table one is slidingly connected with the arc-shaped clamping plate, the bottom of the arc-shaped clamping plate is fixedly connected with the sleeve, the bottom of the sleeve is threadedly connected with the threaded jacking rod, and the top of the arc-shaped clamping plate is provided with a channel.

[0012] Further, the bottom of the placing table one is fixed with a motor through bolts, the bottom of the placing table one is fixed with a transmission box through bolts, one side of the transmission box is movably connected with a transmission shaft, the gear in the transmission box is meshedly connected with the gear at the end of the transmission shaft, the end pulley of the motor drives the gear in the transmission box to rotate, and the outer wall of the transmission shaft is fixedly sleeved with a reel.

[0013] Further, the rotating center shaft of the rotating disc one penetrates the top of the placing table one and is fixed with a rotating disc two through bolts, the rotating disc two is uniformly fixed with limiting columns through bolts, and the limiting columns at the bottom of the rotating disc two are clamped with the reel.

[0014] Further, the outer wall of the transmission shaft is fixedly sleeved with a cam, the bottom of the placing table one is rotationally connected with a rocker through a bearing, one side of the rocker abuts against the outer wall of the cam, and the other side of the rocker abuts against the bottom of the threaded jacking rod.

[0015] The rotary casting method for casting processing specifically comprises:

[0016] Single pouring volume adjustment: By uniformly installing multiple sets of casting molds onto turntable one, the threaded top rod located at the bottom of the sleeve is rotated to assist in the rotation. The height of the top head of the threaded top rod is adjusted. As the motor rotates, the cam on the transmission shaft rotates and begins to squeeze one side of the rocker arm. The rocker arm rotates and lifts up to contact the threaded top rod, pushing the sleeve and arc-shaped clamping plate connected to the threaded top rod to rise. This continuously pushes the clamping pin and one end of the pressure rod in the transmission housing two to lift up. The pressure rod connects to the moving stop block in the transmission housing one. While squeezing the toothed plate to slide, it pushes the entire ladle connected to the transmission teeth to rotate, continuously pouring high-temperature molten metal into the casting mold. The ladle pouring time is calculated, and the total amount of molten metal poured into the casting mold is obtained. The height of the top head of the threaded top rod is controlled according to the method of more lifting and less lowering.

[0017] Alternating feeding and rotary casting: The full ladle is fed into the placement frame using an external lifting device. The limiting plate abuts against the square block on the side of the ladle's rotating shaft. After the rotating plate rotates 180°, the ladle is moved to one side of the turntable. At the same time, the limiting plate disengages from the ladle's rotating shaft side. The motor drives the drive shaft to rotate. The reel on the drive shaft contacts the limiting post and drives the entire turntable two to rotate in 30° increments. The casting molds on turntable one begin to move to the gate side one by one. When the reel rotates but does not drive turntable two to rotate, the cam begins to press down the rocker arm, which finally drives the ladle on the placement frame side to rotate, draining the molten metal and realizing the casting.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, by setting a single drive component to drive the transmission shaft to rotate, multiple casting molds mounted on the turntable can be rotated at a fixed angle. At the same time, the cam rotation drive component is moved to finally realize the rotation of the ladle on the entire placement rack, thereby pouring a quantitative amount of high-temperature molten metal into the casting mold. No personnel contact is required throughout the process, and the casting efficiency is high.

[0020] 2. In this invention, by adjusting the threaded push rod on the bottom sleeve of the lifting mechanism, the placement height of the threaded push rod is controlled. In conjunction with the rotation of the cam, the arc-shaped clamping plate is lifted to different heights, which indirectly controls the downward pressure of the pressure rod in the transmission housing. Ultimately, the downward range of the stop block is controlled, which leads to a reduction in the rotation angle of the transmission teeth in contact with the toothed plate. This controls the quality of the molten metal discharged from the ladle in a single operation. Combined with the total storage volume in the ladle, this ensures that the subsequent casting mold can obtain a more uniform molten metal, avoiding casting deformation problems caused by uneven casting.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0031] Please refer to Figures 1-8 The application provides a technical solution:

[0032] Embodiment 1: Casting forming, also known as casting, is to inject prepared casting raw materials into a mold to solidify, so as to obtain a product similar to the mold cavity, such as Figure 1 and Figure 2As shown, the double-station operation platform of the placing table one 1 and the placing table two 13 is used to control the casting and mold changing by a single drive, and the control of the electronic components on the parts in the high temperature environment is reduced, and the casting work is completed by the mechanical linkage structure;

[0033] The top of the placing table one 1 is provided with the rotating disc one 7, which is matched with the rotating placement of the casting mold 8, and facilitates the subsequent one-by-one rotating casting. For the rotating control of the entire rotating disc one 7, such as Figure 5 As shown, the motor 2 rotates to drive the side belt disc of the transmission box 3 to rotate, and the transmission shaft 4 is rotated through the gear transmission.

[0034] For the assembly installation on the transmission shaft 4, the outer wall of the transmission shaft 4 fixedly connected with the reel 5 at the bottom of the rotating disc two 9. The reel 5 is designed in a special shape, rotates and contacts the limiting column 10 at the bottom of the rotating disc two 9, drives the single limiting column 10 to rotate at intervals, and uses the rotating interval time of the reel 5 to drive the limiting column 10 to rotate. The casting mold 8 is casted, and the casting mold 8 is switched after casting, so as to realize the rotation and alternation of the casting mold 8 and the casting work, and improve the overall casting efficiency.

[0035] The entire reel 5 and the limiting column 10 at the bottom of the rotating disc two 9 are correspondingly arranged, such as Figure 5 As shown, the entire rotating disc one 7 center shaft is connected with the rotating disc two 9, the rotating disc two 9 is provided with 12 limiting columns 10, the included angle between adjacent limiting columns 10 is controlled at 30°, and the rotating disc one 7 is also provided with 12 casting molds 8. Therefore, by changing the reel 5 and controlling the number of limiting columns 10, different sizes of casting molds 8 can be installed on the rotating disc one 7 to drive the casting mold 8 to rotate at different angle units.

[0036] The cam 6 is also sleeved and fixed on the transmission shaft 4, the cam 6 is rotatably connected with the rocker 11 at the bottom of the placing table one 1, and the placing table one 1 on the other side of the rocker 11 is slidably connected with the jacking mechanism 12, as shown: Figure 5 As shown:

[0037] The jacking mechanism 12 is provided with an arc-shaped clamping plate 122 at the top of the placing table one 1, and the arc-shaped clamping plate 122 is fixedly connected with a sleeve 121 at the bottom. The sleeve 121 is threadedly connected with a threaded jack 123 at the bottom, one end of the rocker 11 abuts the edge of the bottom of the threaded jack 123, and the bottom of the placing plate is also provided with a driving assembly. The threaded jack 123 is driven to rotate by driving the clamping plate to rotate, so that the combined length of the threaded jack 123 and the sleeve 121 is changed.

[0038] Since the rotation angle of the cam 6 on the transmission shaft 4 is fixed, the single-side lifting height of the rocker 11 is fixed, and the bottom height of the entire threaded ejector rod 123 is adjusted, so that the end of the rocker 11 contacts the threaded ejector rod 123 earlier, and the lifting height of the arc-shaped clamping plate 122 is also increased;

[0039] For the single lifting height adjustment of the entire arc-shaped clamping plate 122, as shown in Figure 3 and Figure 6 , a clamping column 20 is pulled down at the top of the transmission shell two 19 of the rotating plate 14, as shown in Figure 7 , the entire clamping column 20 is in sliding connection with the transmission shell two 19, and one end of the clamping column 20 in the transmission shell two 19 is in sliding connection with one end of the pressing rod 21. When the entire rotating plate 14 rotates to the placement table one 1 side, one end of the clamping column 20 at the bottom of the transmission shell two 19 is in connection with the groove on the arc-shaped clamping plate 122, causing the entire arc-shaped clamping plate 122 to rise and push the entire clamping column 20 to slide upward, and one end of the pressing rod 21 is lifted while the other end is lowered;

[0040] The transmission shell one 18 is fixedly connected to the side wall of the placement rack 15, the toothed plate 23 and the stopper 22 are in sliding connection in the transmission shell one 18, the toothed plate 23 is horizontally sliding, and the stopper 22 is vertically sliding. One end of the pressing rod 21 abuts against the bottom of the toothed plate 23, and when one end of the entire pressing rod 21 is lowered, the toothed plate 23 also slides downward synchronously, and during the sliding process, the toothed plate 23 on the other side is squeezed, as shown in Figure 8 ;

[0041] The toothed plate 23 slides to the right, as shown in Figure 6 , the transmission teeth 17 are welded and fixed on the side of the ladle 16 installed on the placement rack 15, and the transmission teeth 17 are located at two-thirds of the outer wall of the ladle 16. After the ladle 16 is clamped into the placement rack 15, the ladle 16 is not easy to overturn, and the installed transmission teeth 17 also abut against the toothed plate 23 in the transmission shell one 18. When the toothed plate 23 slides, the rotating transmission teeth 17 also drive the entire ladle 16 to rotate, and the metal liquid in the ladle 16 automatically flows downward;

[0042] Through mechanical structure linkage, the ladle 16 on the placement rack 15 is finally rotated, the discharging work is completed, and the safety of casting production is greatly improved.

[0043] In example 2, considering that the metal liquid in the single-side ladle 16 gradually decreases with the number of casting, if the rotation amplitude of the subsequent ladle 16 is not changed, it is easy to cause that the subsequent casting mold 8 cannot obtain sufficient metal liquid, resulting in that the subsequent casting cannot be formed. Therefore, it is necessary to control the rotation amplitude of the entire ladle 16;

[0044] As shown in Figure 5 ;As shown, the entire threaded push rod 123 is threadedly connected to the sleeve 121. Through the drive assembly installed at the bottom of the placement platform 1, the threaded push rod 123 is driven to rotate, changing the lowest position height of the entire threaded push rod 123. When the threaded push rod 123 moves upward, one end of the entire rocker arm 11 rises. At this time, the contact point between the end of the rocker arm 11 and the threaded push rod 123 changes, while the height of one end of the entire rocker arm 11 is constant. At this time, the lifting height of the entire lifting mechanism 12 is reduced.

[0045] As the arc-shaped clamping plate 122 rises and decreases in height, the clamping post 20 rises and pushes the pressure rod 21 to rotate less, the pressure rod 21 stretches the stop block 22 less, and the sliding distance of the toothed plate 23 decreases. This results in a synchronous decrease in the rotation of the ladle 16. This is suitable for casting a relatively full ladle 16, avoiding the problem of molten metal leakage caused by excessive rotation of the ladle 16. After the entire casting operation is completed, due to the gravity of the ladle 16 itself, the toothed plate 23 is driven to reset. The toothed plate 23 presses the stop block 22 to move upward, realizing the automatic reset of the pressure rod 21, clamping post 20 and lifting mechanism 12.

[0046] When there is less molten metal in the ladle 16, the lifting height of the entire lifting mechanism 12 needs to be adjusted. At this time, the drive component needs to drive the threaded top column to rotate in the opposite direction, increase the combined length of the threaded top column and sleeve 121, and the rocker arm 11 moves to realize the large-angle rotation of the entire ladle 16, so as to discharge the molten metal at the bottom of the ladle 16. Since the casting time and rotation amplitude of the ladle 16 are related to the rotation of the cam 6 on the transmission shaft 4;

[0047] When it is impossible to control a relatively uniform casting operation, the amount of castings cast each time is increased to achieve casting formation, but the subsequent grinding time is relatively increased. The multi-position casting mold 8 is rotated and cast by rotating the turntable 7. At the same time, the casting angle of the ladle 16 can be adjusted to achieve rapid and uniform forming of the castings. At the same time, it prevents the rotation of the ladle 16 during placement, which would cause the molten metal to be discharged and wasted. An electric push rod 24 is also installed on the side of the placement rack 15. The electric push rod 24 is connected to the limiting plate 25, which drives the limiting plate 25 to limit the square rotating shaft end on the side of the ladle 16, avoiding the movement of the rotating plate 14 and the leakage problem that occurs when the ladle 16 is placed.

[0048] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
