Description

Technical Field

[0001] The utility model relates to the technical field of the drag ingot of an electron beam melting furnace, in particular to a drag ingot device for an electron beam melting furnace. Background Art

[0002] An electron beam melting furnace is a device that uses metallurgical processes and purification processes to carry out metal casting. During the casting process, in order to accelerate the melting speed in the furnace to accelerate the casting process, the operation of dragging the ingot is required. The traditional operation of dragging the ingot requires manual operation or manual intervention, with low efficiency. The semi-automatic operation of dragging the ingot will also affect the back-and-forth dragging and generate a large amount of heat, affecting the normal use of the dragged ingot.

[0003] The existing electron beam melting furnace drag ingot device cannot effectively cool down the process of dragging the ingot, and it is easy to be affected by high temperature and affect the normal use. For example, the electron beam melting furnace drag ingot device disclosed in the publication number CN209178449U includes a support frame and a fixed frame. The fixed frames are respectively located at both ends of the support frame. A support frame is provided at the bottom end of the fixed frame. A number of connecting rods are symmetrically arranged on the surface of the support frame. A buffer mechanism is provided at the top end of the connecting rod. The buffer mechanism includes a buffer block, a moving column and a fixed column. A connecting beam is connected between the support frame and the fixed frame. An inclined plate is arranged in an inclined shape between the fixed frames. Fixing rods are symmetrically arranged at the top end of the fixed frame. A dragging mechanism is arranged outside the fixing rods. A ingot placing mechanism is arranged at the bottom end of the dragging mechanism; the dragging mechanism slides along the length direction outside the fixing rods. As the ingot placing box slides, the sliding column vertically moves downward and the second spring is in a contracted state. When the ingot placing box contacts the buffer block, under the elastic action of the third spring, the ingot placing box stops slowly, which is convenient for dragging the melted metal ingot. However, this solution cannot solve the problem of cooling itself during the back-and-forth dragging process. When dragging relatively heavy metals back and forth, high heat will be generated, which will affect the device itself and thus affect the normal use of the device.

[0004] Therefore, it is very necessary to invent an electron beam melting furnace drag ingot device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electron beam melting furnace drag ingot device to solve the problem that high heat is easily generated by friction during the process of dragging the ingot in the electron beam melting furnace, which affects the use.

[0006] To achieve the above object, the present utility model provides the following technical solution: An electronic beam melting furnace ingot dragging device, comprising an ingot, a metal chain, the front end of the device, a base, the middle end of the device and the rear end of the device. The ingot is placed inside the main body of the electronic beam melting furnace. A metal chain is fixedly connected to the ingot, and the metal chain extends into the front end of the device. A base is installed on the front end of the device. The front end of the device is threadedly connected to the middle end of the device, and the middle end of the device is threadedly connected to the rear end of the device. A cylinder is arranged inside the rear end of the device, and the cylinder drives a push rod. The push rod passes through the central part of the fan blade and is threaded.

[0007] Preferably, a coolant inlet is arranged on the middle end of the device. The coolant inlet is communicated with an external coolant container, and a drainage rod is arranged inside the middle end of the device.

[0008] Preferably, the drainage rod is made of resin material, and the drainage rod is arranged at the center of the hollow pipe, and the bottom does not contact the metal chain and the push rod.

[0009] Preferably, a ventilation opening is provided on the rear end of the device.

[0010] Preferably, the extending end of the push rod passing through the fan blade is fixedly connected to the metal chain.

[0011] Preferably, the ingot is made of metal material, and the ingot is spherical. The ingot contacts the bottom of the main body of the electronic beam melting furnace, and the volume of the ingot is one-fifteenth of the volume of the main body of the electronic beam melting furnace.

[0012] Preferably, the end of the front end of the device is directly above the edge of the main body of the electronic beam melting furnace, and the main body of the electronic beam melting furnace is filled with metal solution.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0014] 1. The present utility model drives the cylinder to drag the ingot back and forth. During the process of dragging and moving back and forth inside the main body of the electronic beam melting furnace, the impurities inside the main body of the electronic beam melting furnace are quickly processed and dissolved, accelerating the processing efficiency inside the main body of the electronic beam melting furnace;

[0015] 2. The present utility model accelerates the processing efficiency inside the main body of the electronic beam melting furnace by the back-and-forth movement of the ingot. At the same time, during the process of driving and pushing, the rotation of the fan blade is driven to dissipate heat from the hollow part inside the device, and the surface of the push rod is quickly cooled by using the external coolant and the drainage rod, so that the temperature inside the device will not be too high.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the drawings.

[0024] The present utility model provides an electron beam melting furnace ingot dragging device as shown in Figures 1 - 3 , which includes a metal ingot 2, a metal chain 3, a front end 4 of the device, a base 5, a middle part 6 of the device, and a rear end 7 of the device. The metal ingot 2 is placed in the electron beam melting furnace main body 1, the metal chain 3 is fixedly connected to the metal ingot 2, the metal chain 3 extends into the front end 4 of the device, the base 5 is installed on the front end 4 of the device, the front end 4 of the device is threadedly connected to the middle part 6 of the device, the middle part 6 of the device is threadedly connected to the rear end 7 of the device, a cylinder is arranged in the rear end 7 of the device, the cylinder drives the push rod 8, and the push rod 8 penetrates through the central part of the fan blade 9 and is threaded.

[0025] The entire device can use the cylinder and the push rod 8 to drag the metal ingot 2 back and forth in the electron beam melting furnace main body 1. At the same time, by driving the rotation of the fan blade 9, the surface of the push rod 8 can be cooled, and it will not cause the push rod 8 to be too hot to affect its use.

[0026] A coolant inlet 601 is arranged on the middle part 6 of the device. The coolant inlet 601 is communicated with an external coolant container. A drainage rod 602 is arranged in the middle part 6 of the device. The drainage rod 602 is made of resin material, and the drainage rod 602 is arranged at the center of the hollow pipe and does not contact the metal chain 3 and the push rod 8 at the bottom.

[0027] After the coolant inlet 601 is communicated with the external coolant, the drainage rod 602 can be used to quickly cool the surface of the continuously pushed push rod 8.

[0028] A ventilation opening 701 is opened on the rear end 7 of the device. The extending end of the push rod 8 passing through the fan blade 9 is fixedly connected to the metal chain 3.

[0029] The blowing of the fan blade 9 is used to cool the push rod 8 and the hollow part inside the whole device.

[0030] The metal ingot 2 is made of metal and is spherical. The metal ingot 2 is in contact with the bottom of the electron beam melting furnace body 1. The volume of the metal ingot 2 is one-fifteenth of the volume of the electron beam melting furnace body 1. The end of the front end 4 of the device is directly above the edge of the electron beam melting furnace body 1, and the electron beam melting furnace body 1 is filled with metal solution.

[0031] The moving area of the metal ingot 2 in the electron beam melting furnace body 1 is maximized, so as to quickly process the metal impurities in the electron beam melting furnace body 1 and accelerate the dissolution.

[0032] The working principle of the present utility model:

[0033] Refer to the attached Figures 1 - 3 When using the present utility model, when it is necessary to perform ingot supporting treatment on the metal liquid in the electron beam melting furnace body 1, the cylinder in the device rear end 7 can be started to push the push rod 8 back and forth, and the metal chain 3 is pulled back and forth, so that the metal ingot 2 moves back and forth in the electron beam melting furnace body 1, and the impurities in the electron beam melting furnace body 1 are accelerated to dissolve or are crushed during the process of being dragged by the metal ingot 2;

[0034] Refer to the attached Figures 3 - 5 When using the present utility model, since the push rod 8 needs a large amount of power to drag the metal chain 3, relatively large frictional heat will be generated at the connection part between the push rod 8 or the push rod 8 and the metal chain 3, and it is necessary to cool it. The push rod 8 can be cooled by using an externally connected coolant and a drainage rod 602;

[0035] It is also possible to drive the rotation of the fan blade 9 by the continuous pushing of the push rod 8 to blow air and cool the internal space of the middle part 6 of the device, so as to cool the surface of the push rod 8. The whole ingot supporting process will not cause the temperature of the push rod 8 to be too high and affect the ingot supporting effect.
