Description

Technical Field

[0001] The utility model relates to the technical field of pouring machines, in particular to a metal pouring machine. Background Art

[0002] The pouring machine is a device used to complete the casting pouring in the workshop. It can improve the success rate of castings, reduce the waste of molten iron and the occurrence of burns. With the increasing output of castings and the increasing requirements for casting quality, foundries have begun to pay attention to one of the weak links in casting production, molten iron pouring. Most foundries in my country rely on manual operation of ladles to complete molten iron pouring. Not only are the working conditions poor, the labor intensity is high, but the safety is also poor. With the widespread use of efficient molding equipment, the production rhythm is getting faster and faster, and manual operation is very tense. The production capacity of the molding line is often constrained due to problems in the pouring link, and the scrap rate of castings remains high, the waste of molten iron is serious, and the burns of pouring workers occur from time to time. To change this situation, mechanized and automated pouring machines must be used. In the process of using traditional pouring machines, due to the high temperature of molten iron and slow heat dissipation, it does not pay much attention to the insulation of molten iron, but it still needs to be insulated to a certain extent to prevent it from cooling. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a metal pouring machine.

[0004] According to the technical solution provided in the embodiment of the present application, the metal pouring machine includes a pouring tank body, the upper end face of the pouring tank body is fixedly connected to the electric rotating connector through a bearing, the electric heating tube arranged in the pouring tank body is electrically connected to the electric rotating connector, the electric heating tube is slidably connected to the annular slide rail on the top end face of the pouring tank body through a connecting tube, and under the action of the electric rotating connector, the electric heating tube stirs the liquid in the pouring tank body while dissipating heat.

[0005] Furthermore, the electric heating tube is a U-shaped tube or a serpentine tube, which facilitates the flow of multiple liquids in the pouring tank.

[0006] Furthermore, a pouring trough is provided at the upper end of the pouring tank body to facilitate the outflow of liquid in the pouring tank body.

[0007] Furthermore, one end face of the casting tank body is connected to the U-shaped support frame through an angle adjustment component, and the other end face is connected to the U-shaped support frame through a rotating shaft. The lower end face of the casting tank body is fixedly connected to the U-shaped support frame through a stabilizing spring to realize the rotation of the casting tank body relative to the U-shaped support frame.

[0008] Furthermore, the angle adjustment assembly includes an auxiliary gear, a transmission gear and a transmission motor. The auxiliary gear is meshed with the transmission gear. The transmission motor is connected to the transmission gear through a motor shaft. The angle adjustment assembly is fixedly connected to one end face of the casting tank body through a connecting column, so that the connection between the casting tank body and the angle adjustment assembly is more stable.

[0009] Furthermore, a heat-insulating shell is provided on the outer end surface of the pouring tank body to reduce the loss of liquid temperature in the pouring tank body.

[0010] Furthermore, the electric heating tube is connected to the temperature control device via an electric rotating connector to prevent the electric heating tube from being continuously heated and affecting the life of the electric heating tube.

[0011] To sum up, the beneficial effects of the present application are as follows: the device of the present application arranges an electric heating tube inside the casting machine through an electric rotating connector. The electric heating tube can heat and keep warm to prevent the molten iron from cooling down, and at the same time, it can stir the liquid in the casting machine. At the same time, since the temperature of the electric heating tube can reach the melting temperature of the molten iron, it is difficult for the molten iron to solidify on the stirring electric heating tube, thereby reducing losses.

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Metal pouring machines, such as Figure 1 , Figure 2 and Figure 4 As shown, the pouring tank body 1 is connected to the U-shaped support frame 7 with the opening upward through the angle adjustment component 6 and the rotating shaft 8. One end face of the angle adjustment component 6 is fixedly connected to the pouring tank body 1 through the connecting column 10, and the other end face is fixedly connected to the U-shaped support frame 7. The lower end face of the pouring tank body 1 is fixedly connected to the bottom face of the U-shaped support frame 7 through a plurality of stabilizing springs 9.

[0022] like Figure 3 As shown, an electric rotary connector 2 is fixedly provided at the middle part of the upper end surface of the casting tank body 1 through a bearing, and the lower end surface of the electric rotary connector 2 is electrically connected to an electric heating tube 3, which is a U-shaped tube or a serpentine tube and is placed in the casting tank body 1. The upper end surface of the electric heating tube 3 is slidably connected to an annular slide rail 5 fixed on the top end surface of the casting tank body 1 through a connecting tube 4, and there are at least two connecting tubes 4. A casting trough 11 is provided on the right end surface of the casting tank body 1, and the casting trough 11 is fixedly passed through the heat-insulating shell sleeved on the outer end surface of the casting tank body 1;

[0023] like Figure 4 and Figure 5 As shown, the angle adjustment assembly 6 includes an auxiliary gear 61, a transmission gear 62 and a transmission motor 63. The auxiliary gear 61 is meshed with the transmission gear 62. The transmission motor 63 is connected to the transmission gear 62 through a motor shaft. The transmission motor 63 is fixed on the vertical plate of the U-shaped support frame 7. The auxiliary gear 61 and the transmission gear 62 are both rotatably fixed on the vertical plate of the U-shaped support frame 7.

[0024] When in use, since the electric heating tube 3 is connected to the temperature control device through the electric rotating connector 2, the heating temperature of the electric heating tube 3 can be set during the heating process;

[0025] After the electric rotary connector 2 is started, the electric heating tube 3 is heated and rotates in the casting tank body 1. Figure 3 It is shown as a vertical tube, so the electric heating tube 3 can stir the liquid in the casting tank body 1 while rotating, that is, the electric heating tube 3 can heat up or even keep the liquid in the casting tank body 1 while stirring the liquid.

[0026] The pouring tank body 1 is supported by multiple stabilizing springs 9, and is more firmly connected to the U-shaped support frame 7;

[0027] When pouring is required, the transmission motor 63 on the angle adjustment component 6 is started to drive the transmission gear 62 to rotate. Since the transmission gear 62 is meshed with the auxiliary gear 61, the auxiliary gear 62 also rotates accordingly. At the same time, since the auxiliary gear 62 is fixedly connected to the pouring tank body 1 through a plurality of connecting columns 10, when the auxiliary gear 62 rotates, the other end face of the pouring tank body 1 is rotatably connected to the U-shaped support frame 7 through the rotating shaft 8, which will drive the rotation of the pouring tank body 1, that is, the tilting angle of the pouring tank body 1 is realized. At this time, the liquid in the pouring tank body 1 can flow out of the pouring trough 11 to complete the pouring.

[0028] The electric heating tube 3 can be replaced with a high temperature resistant stirring device, and an arc heating device with a nozzle facing downward is arranged above the electric heating tube 3 to achieve efficient heating and heat preservation in the casting tank body 1.
