[0005] For the problems existing in the prior art, the centrifugal casting blanking tooling provided by the utility model can easily pull out the material rod from the centrifugal casting equipment, and the stroke of the tooling is small, reducing the floor area of the workshop.

[0010] One ends of the two second connecting rods are respectively hinged to one ends of the two first connecting rods, the other ends of the second connecting rods are provided with semi-cylinders, the arc surfaces of the semi-cylinders are provided with patterns, the arc surfaces of the semi-cylinders on the two second connecting rods are far away from each other, and the telescopic movement of the telescopic rod can drive the semi-cylinders at the ends of the two second connecting rods to approach or move away from each other through the two first connecting rods.

[0011] Preferably, the telescopic driving device is an oil cylinder.

[0012] Preferably, the texture on the arc surface of the semi-cylinder is configured as a thread.

[0013] Preferably, the second connecting rod is configured as a Z-shaped rod, one end of which is provided with a semi-cylinder, and one end of two Z-shaped rods provided with the semi-cylinders are close to each other and hinged to the second radial hinge shaft;

[0014] The other ends of the two Z-shaped rods are away from each other and are hinged to the ends of the first connecting rods respectively.

[0015] Preferably, the diameter of the semi-cylinder is smaller than the inner hole diameter of the material rod.

[0025] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 4As shown in the figure, a feeding tool for centrifugal casting includes a connecting seat 1. A through hole 9 is provided at the center of the connecting seat 1. A movable telescopic rod 8 is provided in the through hole 9. One end of the telescopic rod 8 is provided with a telescopic driving device, and the telescopic driving device is fixed on the connecting seat 1 at one end of the through hole 9. The telescopic driving device is preferably set as an oil cylinder.

[0027] In the utility model, the other end of the telescopic rod 8 is provided with a first radial hinge shaft 7. Two first connecting rods 6 are hinged on the first radial hinge shaft 7. Two fixing rods 2 are provided at both ends of the radial hinge shaft. The two fixing rods 2 are fixedly connected to the connecting seat 1. A second radial hinge shaft 4 is provided between the ends of the two fixing rods 2 away from the connecting seat 1. Two second connecting rods 3 are hinged on the second radial hinge shaft 4.

[0028] One end of each of the two second connecting rods 3 is respectively hinged to one end of the two first connecting rods 6. The other end of the second connecting rod 3 is provided with a semi-cylindrical body 5. Threads are provided on the arc surface of the semi-cylindrical body 5. The threads are preferably set as screw threads. The arc surfaces of the semi-cylindrical bodies 5 on the two second connecting rods 3 are away from each other. The telescopic movement of the telescopic rod 8 can drive the semi-cylinders 5 at the ends of the two second connecting rods 3 to approach or move away from each other through the two first connecting rods 6.

[0029] In the utility model, two semi-cylinders 5 with threads are used to open and support the inner wall of the material rod, and then the material rod is pulled out from the centrifugal casting equipment. Compared with the traditional method, the telescopic stroke of the telescopic rod 8 is reduced, and the floor area of the workshop is correspondingly reduced.

[0030] Specifically, the second connecting rod 3 is set as a Z-shaped rod. One end of the Z-shaped rod is provided with a semi-cylindrical body 5. One ends of the two Z-shaped rods provided with the semi-cylindrical bodies 5 are close to each other and are hinged to the second radial hinge shaft 4. The other ends of the two Z-shaped rods are away from each other and are respectively hinged to the ends of the first connecting rod 6. The other end of the first connecting rod 6 is hinged to the first radial hinge shaft 7. The transmission between the second connecting rod 3 and the second radial hinge shaft 4 is similar to a lever structure, which can ensure the opening force of the two semi-cylinders 5.

[0031] In the utility model, the diameter of the semi-cylindrical body 5 is smaller than the inner diameter of the material rod, so as to ensure that when the two semi-cylindrical bodies 5 are in contact, they can extend into the inner hole of the material rod, and when the two semi-cylinders 5 with threads are opened, it needs to be larger than the inner diameter of the material rod.

[0032] Specifically, when the ends of the semi-cylindrical bodies 5 away from the second connecting rod 3 are in contact with each other, the semi-cylindrical bodies 5 on the two second connecting rods 3 can be spliced into a complete cylinder, so as to ensure that they can extend into the inner hole of the material rod. There is a gap between one ends of the two Z-shaped rods provided with the semi-cylindrical bodies 5, so as to ensure that there is a certain movement space when the two semi-cylindrical bodies 5 are opened.

[0033] Before pulling the material of the present utility model, it is necessary to first drive the telescopic rod 8 to extend through the telescopic driving device. At this time, the telescopic rod 8 can drive the semi-cylinders 5 at the ends of the two second connecting rods 3 to approach each other through the two first connecting rods 6, and the overall movement of the connecting seat 1 drives the two semi-cylinders 5 to extend into the inner hole of the material rod;

[0034] Then the telescopic driving device drives the telescopic rod 8 to retract. At this time, the telescopic rod 8 can drive the semi-cylinders 5 at the ends of the two second connecting rods 3 to move away from each other through the two first connecting rods 6, and the two semi-cylinders 5 open to support the inner wall of the material rod. Finally, the connecting seat 1 retreats to pull the material rod out of the centrifugal casting equipment.

[0035] It should be understood that the use of these embodiments is only for illustrating the present utility model and is not intended to limit the protection scope of the present utility model. In addition, it should also be understood that after reading the technical content of the present utility model, those skilled in the art can make various changes, modifications and / or variations to the present utility model, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
