Description

Technical Field

[0001] The utility model relates to the technical field of semi-solid slurry stirring devices, and specifically relates to a stirring device for preparing semi-solid slurry. Background Technique

[0002] Semi-solid slurry is a special form of metal material, and its characteristic is that only 10% - 50% of the metal in its composition is in a liquid state, and the rest is in a solid state. This special form makes the semi-solid slurry present a laminar flow pattern when flowing, and during the pressure casting process, the castings have less gas entrapment, complete filling, and the casting structure is dense.

[0003] Semi-solid slurry materials have many advantages during the casting process. For example, they can greatly reduce the tendency to form shrinkage cavities. There are no shrinkage porosity and shrinkage cavities inside the castings, the structure is dense, and the airtightness is good. At the same time, the semi-solid billets have less solidification shrinkage and smooth filling, can process complex parts, and extend the service life of the parts. In addition, due to the viscosity and rheology of semi-solid slurry, reinforcing materials such as fibers and second-phase particles can be added to prepare composite materials.

[0004] The patent with the publication number CN212822571U discloses a semi-solid slurry stirring device, which specifically discloses the technical solution of "a semi-solid slurry stirring device, including a frame, a first power system, a barrel rotation and vibration device, a barrel Y-direction vibration device, a stirring rotation device, a second power system, a double worm and gear mechanism, a barrel, and a stirring rod", and realizes the technical effect of "a semi-solid slurry stirring device of the utility model, the stirring and vibration device can make the stirring rod perform a reciprocating motion in the Y direction while stirring, thereby generating an axial shear force; when the stirring rotation and vibration device stirs in the slurry, it generates a reciprocating motion in the X direction, forming a radial shear force: the barrel rotation and vibration device can drive the barrel to rotate and generate reciprocating motions in the X and Y directions at the same time, making the slurry rotate and vibrate as a whole. Under the combined action of these three devices and the organic combination of the local and the whole, the slurry is stirred more thoroughly, improving the efficiency and quality of preparing semi-solid slurry of metals and alloys".

[0005] However, the semi-solid slurry stirring operation of this patent is carried out in a barrel container like the conventional technology. However, when transferring from the barrel container to the mold after stirring, the problem of loss of semi-solid slurry during the transfer to the mold cannot be overcome. Therefore, more semi-solid slurry needs to be prepared in advance, which will cause more waste when manufacturing semi-solid molds in batches, and there is room for improvement. Summary of the Invention

[0006] The purpose of the utility model is to provide a stirring device for preparing semi-solid slurry to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A stirring device for preparing semi-solid slurry, comprising a stirring tube sleeve, a stirring tube, an adsorbing member and a connecting body. One end of the stirring tube sleeve is fixedly connected with a tube sleeve ring. The stirring tube is embedded inside the stirring tube sleeve, and one end of the stirring tube is fixedly connected with a telescopic fork head. One end of the telescopic fork head passes through the tube sleeve ring and the adsorbing member and extends to the outside of the adsorbing member. The connecting body includes a connecting ring, a connecting rod and a fixing ring. The fixing ring is sleeved on the outer periphery of the stirring tube sleeve. The connecting ring is fixedly connected with the fixing ring through the connecting rod. The end of the stirring tube away from the telescopic fork head is fixedly connected with a stirring disc, and the stirring disc is rotatably connected with the connecting ring.

[0008] Compared with the prior art, the beneficial effects of the present utility model are:

[0009] As a further scheme of the present utility model: A stirring device for preparing semi-solid slurry, the adsorbing member includes an adsorption head, a loop and a soft rod. One end of the soft rod is fixedly connected with the loop, and the other end is fixedly connected with the adsorption head. The loop is sleeved on the outside of the tube sleeve ring and is movably connected with the tube sleeve ring through a screw. The connection state between the loop and the tube sleeve ring can be adjusted through the screw, and the adjustment is convenient. The stirring tube sleeve can be stabilized and restrained through the adsorbing member, avoiding the problem that the telescopic fork head comes out of the gate of the semi-solid mold when the stirring tube drives the stirring tube sleeve to swing during rotation.

[0010] As a further scheme of the present utility model: A stirring device for preparing semi-solid slurry, the stirring disc is embedded inside the connecting ring. Baffles are arranged at both ends of the stirring disc and are movably connected with the connecting ring. By arranging baffles at both ends of the stirring disc, it can prevent the stirring disc from falling off the connecting ring during rotation and maintain the stability of the rotation of the stirring disc.

[0011] As a further scheme of the present utility model: A stirring device for preparing semi-solid slurry, three groups of telescopic fork heads are annularly arrayed with the axis as the base. The telescopic fork head is entirely made of spring steel and has good elasticity. It can be retracted before entering the gate of the semi-solid mold and will open after entering, increasing the contact area with the semi-solid mold slurry, thereby effectively enhancing the stirring effect of the device.

[0012] As a further scheme of the present utility model: A stirring device for preparing semi-solid slurry, one end of the adsorption head is fixedly connected with a suction cup and a magnetic sticker. The suction cup and the magnetic sticker are both annularly arrayed on one side of the adsorption head and are arranged alternately. The magnetic sticker realizes the positioning effect, and the suction cup realizes the adsorption effect, which can avoid the problem that the front end shakes during the rotation of the stirring device, resulting in the separation of the telescopic fork head from the gate.

[0013] As a further solution of the present utility model: A stirring device for preparing semi-solid slurry, one side of the stirring disk is fixedly connected with a handle, and anti-slip patterns are arranged on the outer periphery of the handle. The handle facilitates the stirring tube to drive the telescopic fork head to rotate and stir in the semi-solid mold.

[0014] To sum up, the main beneficial effects of the present utility model are as follows:

[0015] 1. Since the telescopic fork head extends to the outside of the suction accessory after passing through the tube sleeve ring and the suction accessory, and the stirring disk is rotatably connected with the connecting ring, when in use, after inserting the telescopic fork head into the semi-solid mold through the gate, rotating the stirring disk can make the stirring tube drive the telescopic fork head to rotate and stir in the semi-solid mold;

[0016] 2. Since the telescopic fork head is made of spring steel and has a fork-shaped structure, it will open after penetrating into the semi-solid mold to enhance the stirring effect of the device. And the telescopic fork heads are distributed in three groups in an annular array based on the axis and the whole telescopic fork head is made of spring steel. Therefore, the telescopic fork head has good elasticity. It can be retracted before entering the gate of the semi-solid mold and will open after entering, increasing the contact area with the semi-solid mold slurry, thereby effectively enhancing the stirring effect of the device.

[0017] 3. The connection state between the sleeve and the tube sleeve ring can be adjusted by the screw. When stirring operation of the semi-solid mold is required, the device can be positioned and adsorbed through the suction accessory and the tube sleeve ring. Specifically, the screw and the sleeve control the position of the suction accessory on the tube sleeve ring to make the adsorption head fit the semi-solid mold. The outer part of the semi-solid mold is adsorbed through the suction cup and the magnetic sticker on one side of the adsorption head, and then the telescopic fork head is inserted into the semi-solid mold. During the process, the suction accessory can stabilize and restrain the stirring tube sleeve, avoiding the problem that the telescopic fork head disengages from the gate of the semi-solid mold due to the swinging of the stirring tube sleeve driven by the rotation of the stirring tube.

The following will describe the embodiments according to the overall structure of the present invention.

[0026] In an embodiment of the present utility model, a stirring device for preparing semi-solid slurry includes a stirring tube sleeve 1, a stirring tube 2, an adsorbing member 3, and a connecting body 4. One end of the stirring tube sleeve 1 is fixedly connected with a tube sleeve ring 5. The stirring tube 2 is embedded inside the stirring tube sleeve 1, and one end of the stirring tube 2 is fixedly connected with a telescopic fork head 21. One end of the telescopic fork head 21 passes through the tube sleeve ring 5 and the adsorbing member 3 and extends to the outside of the adsorbing member 3. There are three groups of the telescopic fork heads 21 distributed in a circumferential array with the axis as the base, and the telescopic fork heads 21 are entirely made of spring steel. The connecting body 4 includes a connecting ring 41, a connecting rod 42, and a fixing ring 43. The fixing ring 43 is sleeved on the outer periphery of the stirring tube sleeve 1, and the connecting ring 41 is fixedly connected with the fixing ring 43 through the connecting rod 42. One end of the stirring tube 2 away from the telescopic fork head 21 is fixedly connected with a stirring disc 22. The stirring disc 22 is rotatably connected with the connecting ring 41. The stirring disc 22 is embedded inside the connecting ring 41. Both ends of the stirring disc 22 are provided with baffles and are movably connected with the connecting ring 41. One side of the stirring disc 22 is fixedly connected with a handle 23, and anti-slip patterns are provided on the outer periphery of the handle 23.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , since the telescopic fork head 21 passes through the tube sleeve ring 5 and the adsorbing member 3 and extends to the outside of the adsorbing member 3, and the stirring disc 22 is rotatably connected with the connecting ring 41, when in use, after inserting the telescopic fork head 21 into the semi-solid mold through the gate, rotating the stirring disc 22 can make the stirring tube 2 drive the telescopic fork head 21 to rotate and stir in the semi-solid mold. Since the telescopic fork head 21 is made of spring steel and has a fork-shaped structure, it will open after penetrating into the semi-solid mold and enhance the stirring effect of the device. Moreover, there are three groups of the telescopic fork heads 21 distributed in a circumferential array with the axis as the base and the telescopic fork heads 21 are entirely made of spring steel. Therefore, the telescopic fork head 21 has good elasticity. It can be converged and inserted before entering the gate of the semi-solid mold, and will open and increase the contact area with the semi-solid mold slurry after entering, so as to effectively enhance the stirring effect of the device. And because one side of the stirring disc 22 is fixedly connected with a handle 23, when in use, a worker can hold the connecting rod 42 with one hand and hold the handle 23 with the other hand to rotate, so that the stirring tube sleeve 1 does not rotate while the stirring tube 2 rotates. Then, driving the telescopic fork head 21 to rotate by the rotation of the stirring tube 2 can accelerate the stirring operation of the semi-solid mold.

[0028] As another embodiment of the present utility model: The adsorbing member 3 includes an adsorption head 31, a ring 32, and a flexible rod 33. The flexible rod 33 is made of rubber. One end of the flexible rod 33 is fixedly connected with the ring 32, and the other end is fixedly connected with the adsorption head 31. The ring 32 is sleeved on the outside of the tube sleeve ring 5 and is movably connected with the tube sleeve ring 5 through a screw 36.

[0029] Please refer to Figure 2 and Figure 5 As shown in Figure 2 and Figure 5 , the connection state between the snare 32 and the sleeve ring 5 can be adjusted by the screw 36. When the stirring operation of the semi-solid mold is required, the device can be positioned and adsorbed through the adsorbing part 3 and the sleeve ring 5. Specifically, the screw 36 and the snare 32 control the position of the adsorbing part 3 on the sleeve ring 5 and make the adsorption head 31 fit the semi-solid mold. The external part of the semi-solid mold is adsorbed through the suction cup 34 and the magnetic sticker 35 on one side of the adsorption head 31, and then the telescopic fork head 21 is inserted into the semi-solid mold. During this process, the adsorbing part 3 can stabilize and restrain the stirring sleeve 1, avoiding the problem that the telescopic fork head 21 disengages from the gate of the semi-solid mold due to the swinging of the stirring sleeve 1 driven by the rotation of the stirring tube 2.

[0030] Since the flexible rod 33 is made of rubber, the flexible rod 33 can be used for the extended connection between the snare 32 and the adsorption head 31, and avoid the problem of damage to the adsorbing part 3 caused by the folding of one end of the stirring sleeve 1.

[0031] As another embodiment of the present utility model: the stirring disc 22 is embedded inside the connecting ring 41, and baffles are arranged at both ends of the stirring disc 22 and are movably connected with the connecting ring 41.

[0032] Please refer to Figure 1 and Figure 2 As shown in Figure 1 and Figure 2 , by arranging baffles at both ends of the stirring disc 22, it can prevent the stirring disc 22 from detaching from the connecting ring 41 when rotating and maintain the stability of the rotation of the stirring disc 22.

[0033] As another embodiment of the present utility model: three groups of telescopic fork heads 21 are distributed in a circumferential array with the axis as the base, and the telescopic fork heads 21 are entirely made of spring steel.

[0034] Please refer to Figure 3 As shown in Figure 3 , since three groups of telescopic fork heads 21 are distributed in a circumferential array with the axis as the base and the telescopic fork heads 21 are entirely made of spring steel, the telescopic fork heads 21 have good elasticity. Before entering the gate of the semi-solid mold, they can be retracted and enter, and after entering, they will open and increase the contact area with the semi-solid mold slurry, thereby effectively enhancing the stirring effect of the device.

[0035] As another embodiment of the present utility model: one end of the adsorption head 31 is fixedly connected with a suction cup 34 and a magnetic sticker 35, and the suction cup 34 and the magnetic sticker 35 are both distributed in a circumferential array on one side of the adsorption head 31 and are arranged alternately.

[0036] Please refer to Figure 5, since both the suction cups 34 and the magnetic tiles 35 are arranged in a circular array on one side of the suction head 31 and are arranged alternately, the suction cups 34 and the magnetic tiles 35 are actually evenly distributed with an angular difference of 60°. When the suction head 31 contacts the semi-solid mold, the suction head 31 can be quickly connected to the semi-solid mold by the adsorption of the magnetic tiles 35. Then, by pressing the suction head 31, the suction cups 34 can discharge air and achieve a firm adsorption between the suction head 31 and the semi-solid mold, which can avoid the problem that the front end shakes when the stirring device rotates, resulting in the separation of the telescopic fork head 21 from the gate.

[0037] As another embodiment of the present invention: One side of the stirring disc 22 is fixedly connected with a handle 23, and anti-slip lines are provided on the outer periphery of the handle 23.

[0038] Please refer to Figure 3 , since one side of the stirring disc 22 is fixedly connected with a handle 23, when in use, a staff member can hold the connecting rod 42 with one hand and hold the handle 23 with the other hand to rotate, so that the stirring tube sleeve 1 does not rotate while the stirring tube 2 rotates. Then, the rotation of the stirring tube 2 drives the telescopic fork head 21 to rotate, which can accelerate the stirring operation of the semi-solid mold.

[0039] The working principle of the present invention is: Since the telescopic fork head 21 passes through the tube sleeve ring 5 and the adsorbent 3 and extends to the outside of the adsorbent 3, and the stirring disc 22 is rotatably connected with the connecting ring 41, when in use, after the telescopic fork head 21 is inserted into the semi-solid mold through the gate, rotating the stirring disc 22 can make the stirring tube 2 drive the telescopic fork head 21 to rotate and stir in the semi-solid mold.

[0040] Since the telescopic fork head 21 is made of spring steel and is in a fork-shaped structure, it will open after penetrating into the semi-solid mold and enhance the stirring effect of the equipment. And the telescopic fork head 21 is arranged in three groups in a circular array based on the axis and the whole body of the telescopic fork head 21 is made of spring steel. Therefore, the telescopic fork head 21 has good elasticity. It can be retracted before entering the gate of the semi-solid mold and will open after entering, increasing the contact area with the slurry of the semi-solid mold, thereby effectively enhancing the stirring effect of the equipment.

[0041] Since one side of the stirring disc 22 is fixedly connected with a handle 23, when in use, a staff member can hold the connecting rod 42 with one hand and hold the handle 23 with the other hand to rotate, so that the stirring tube sleeve 1 does not rotate while the stirring tube 2 rotates. Then, the rotation of the stirring tube 2 drives the telescopic fork head 21 to rotate, which can accelerate the stirring operation of the semi-solid mold.

[0042] The connection state between the snare 32 and the tube collar 5 can be adjusted by the screw 36. When the stirring operation of the semi-solid mold is required, the device can be positioned and adsorbed through the adsorbent 3 and the tube collar 5. Specifically, the screw 36 and the snare 32 control the position of the adsorbent 3 on the tube collar 5 and make the suction head 31 fit the semi-solid mold. The outer part of the semi-solid mold is adsorbed through the suction cup 34 and the magnetic patch 35 on one side of the suction head 31, and then the telescopic fork head 21 is inserted into the semi-solid mold. During the process, the adsorbent 3 can stabilize and restrain the stirring tube sleeve 1, avoiding the problem that the telescopic fork head 21 disengages from the gate of the semi-solid mold when the stirring tube 2 rotates and drives the stirring tube sleeve 1 to swing.

[0043] Since the flexible rod 33 is made of rubber, the flexible rod 33 can be used for the extended connection between the snare 32 and the suction head 31, and avoid the problem that the adsorbent 3 is damaged due to the folding of one end of the stirring tube sleeve 1.

[0044] By arranging baffles at both ends of the stirring disk 22, it can prevent the stirring disk 22 from falling off the connecting ring 41 when rotating and maintain the stability of the rotation of the stirring disk 22.

[0045] Since the suction cups 34 and the magnetic patches 35 are both arranged in an annular array on one side of the suction head 31 and are arranged alternately, the suction cups 34 and the magnetic patches 35 are actually evenly divided at an angle difference of 60°. When the suction head 31 contacts the semi-solid mold, the suction head 31 can be quickly connected to the semi-solid mold through the adsorption of the magnetic patch 35, and then the suction head 31 is squeezed to discharge the air from the suction cups 34 and achieve the firm adsorption of the suction head 31 to the semi-solid mold, which can avoid the problem that the front end shakes when the stirring device rotates and the telescopic fork head 21 disengages from the gate.

[0046] Since a handle 23 is fixedly connected to one side of the stirring disk 22, during use, the operator can hold the connecting rod 42 with one hand and the handle 23 with the other hand to rotate, so that the stirring tube sleeve 1 does not rotate while the stirring tube 2 rotates. Then, the rotation of the stirring tube 2 drives the telescopic fork head 21 to rotate, which can accelerate the stirring operation of the semi-solid mold.

[0047] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
