Technical Field

[0001] The present application relates to the technical field of mechanical processing, and in particular to a high-efficiency strip metal pressing mechanism. Background Art

[0002] Columnar ingots of metal can be formed into strips of metal after being pressed. When the columnar metal ingots leave the factory, protruding terminals are usually reserved at their ends to facilitate downstream manufacturers to grab or smelt them through electricity during processing.

[0003] In the prior art, a cylindrical metal ingot is generally pushed into a pressing chamber for pressing by using an oil cylinder. Each metal ingot requires a single loading, that is, after the previous metal ingot is pressed, an operator is required to carry the metal ingot for loading operations.

[0004] For example, in the Chinese utility model patent application document with publication number CN218395498U, a strip metal pressing mechanism is disclosed. After the first hydraulic cylinder returns after pushing the material, the operator still needs to manually load the metal ingot into the feeding pipe. The loading time is long, the waiting time in the pressing room is long, and the overall pressing efficiency is not high. Summary of the invention

In this way, after the previous metal ingot is completed pressed, the subsequent metal ingot can quickly enter the feed pipe for feeding, and there is no need for the operator to load the ingots one by one while waiting in the pressing chamber, thereby reducing the labor intensity of the operator and the waiting time of the pressing chamber when it is idle, and significantly improving the overall pressing efficiency.

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] The embodiment of the present application provides a high-efficiency strip metal pressing mechanism, comprising a pressing chamber 10 for pressing a metal ingot into a metal strip, a feeding pipe 20 for feeding materials into the pressing chamber 10, and a waiting bin 30 for temporarily storing the metal ingot;

[0029] The feed pipe 20 is hollow inside and open at both ends. The central axis of the feed pipe 20 is parallel to the central axis of the feed port of the pressing chamber 10. One end of the feed pipe 20 is a discharge end, and the discharge end of the feed pipe 20 is located at the feed port of the pressing chamber 10. A feed port 21 for feeding metal ingots is provided on the side of the feed pipe 20. The cross-sectional shape of the feed port 21 is arc-shaped. A feed cylinder 40 is provided at one end of the feed pipe 20 away from the discharge end. The telescopic head of the feed cylinder 40 extends into the inner side of one end of the feed pipe 20 away from the pressing chamber 10. The cylinder body of the feed cylinder 40 and the feed pipe 20 are both fixed relative to the pressing chamber 10.

[0030] The waiting bin 30 is arranged on one side of the feed pipe 20, and the discharge port of the waiting bin 30 is connected to the feed port 21 on the side of the feed pipe 20. Two parallel guide rails 31 are fixedly connected to the bottom of the waiting bin 30, and a plurality of rotating shafts 32 are rotatably connected to the bottom of the guide rails 31. The central axes of the plurality of rotating shafts 32 are perpendicular to the central axis of the guide rails 31, and the two ends of the rotating shafts 32 are respectively located on both sides of the guide rails 31. A cross dial 33 is fixedly connected to both ends of the rotating shaft 32, and at least one of the four forks of the cross dial 33 is always at the top of the guide rail 31. A driving device 34 for driving the rotating shaft 32 to rotate is installed at one end of the rotating shaft 32.

[0031] The following is a further introduction based on specific usage scenarios.

[0032] When in use, the operator first places several metal ingots to be processed on the guide rail 31 of the waiting bin 30, with the central axes of the metal ingots perpendicular to the central axis of the guide rail 31. The metal ingots close to the feed pipe 20 slide toward the feed pipe 20 under the extrusion of subsequent metal ingots until they touch the cross dial 33 installed on the rotating shaft 32 away from the feed pipe 20.

[0033] When feeding is required, the plurality of rotating shafts 32 rotate under the drive of the driving device 34, and the two cross dials 33 installed on the same rotating shaft 32 rotate accordingly, and the shift fork on the cross dial 33 pushes the metal ingot to move in the direction close to the feeding pipe 20, and the metal ingot closest to the feeding pipe 20 falls into the feeding pipe 20 under the push of the cross dial 33, and then the operator opens the feeding cylinder 40, and the feeding cylinder 40 extends the telescopic head, so that the telescopic head pushes the metal ingot to move in the feeding pipe 20 in the direction of the pressing chamber 10, until the end of the metal ingot away from the feeding cylinder 40 is engaged by the pressing roller pair in the pressing chamber 10;

[0034] After the previous metal ingot is bitten by the pressing chamber 10, the operator can move the telescopic head of the feed cylinder 40 away from the pressing chamber 10, so that the feed port 21 of the feed pipe 20 is completely exposed. At this time, the operator turns on the drive device 34 again, so that the subsequent metal ingots fall from the feed port 21 into the feed pipe 20 driven by the cross dial 33 to complete the loading.

[0035] It can be found that in the embodiment of the present application, after the previous metal ingot is bitten by the pressing chamber 10, the subsequent metal ingot can quickly enter the feed pipe 20 to wait for feeding, and there is no need for the operator to load the ingots one by one while the pressing chamber 10 is waiting, thereby reducing the labor intensity of the operator and the waiting time of the pressing chamber 10 hanging unloaded, and significantly improving the overall pressing efficiency.

[0036] In the embodiment of the present application, the guide rail 31 plays the role of temporarily placing metal ingots and limiting the rolling direction of the metal ingots. The guide rail 31 can be regarded as a temporary shelf for the metal ingots in the waiting bin 30. The cross dial wheels 33 installed at both ends of the rotating shaft 32 play the role of blocking and driving the metal ingots. In the embodiment of the present application, there are two rotating shafts 32, and the two rotating shafts 32 are independent of each other. The two rotating shafts 32 divide the space on the guide rail 31 into a storage area, a waiting area and a feeding area. The storage area is an area sandwiched by one end of the guide rail 31 away from the feed pipe 20 and the rotating shaft 32 away from the feed pipe 20. The waiting area is an area sandwiched by the two rotating shafts 32. The feeding area is the rotating shaft 32 close to the feed pipe 20. The area on one side of the feed pipe near the shaft 32, during the actual feeding process, the metal ingots in the waiting area are first fed into the feeding area through the feed pipe, and as the rotating shaft 32 rotates, the metal ingots in the storage area near the edge of the waiting area will enter the waiting area to wait for feeding. This process only requires the operator to control the start and stop of the drive device 34. When the metal ingots in the storage area are sufficient, there is no need for the operator to manually load the materials. When the metal ingots in the storage area are exhausted, the metal ingots in the waiting area can be fed normally. During the feeding of the metal ingots in the waiting area, the operator can add metal ingots to the waiting bin 30, which does not occupy the waiting time of the pressing chamber 10, thereby improving the overall pressing efficiency.

[0037] The guide rail 31 in the waiting bin 30 can be tilted, and the height of the end of the guide rail 31 away from the feed port 21 of the feed pipe 20 is higher than the height of the end of the guide rail 31 close to the feed port 21 of the feed pipe 20. The end of the guide rail 31 close to the feed port 21 of the feed pipe 20 is bent downward to form a bending portion 37, and the bending portion 37 is located at the feed port 21 of the feed pipe 20, and the bending portion 37 is located in the feeding area. In this way, the metal ingots at the top of the guide rail 31 have a tendency to enter the feed pipe 20. Under the fluctuation of the cross dial 33, the metal ingots can quickly move toward the feed pipe 20 and enter the feed pipe 20, which reduces the labor intensity of the operator and the waiting time of the pressing chamber 10 hanging up without load, and improves the overall pressing efficiency.

[0038] The telescopic head of the feed cylinder 40 is an actuator that pushes the metal ingot to feed in the direction of the feed pipe. In the embodiment of the present application, a feed column 41 is fixedly connected to the end of the telescopic head of the feed cylinder 40. The feed column 41 is located in the feed pipe 20. The diameter of the feed column 41 is larger than the diameter of the telescopic head of the feed cylinder 40. An accommodating groove for accommodating the metal ingot terminal is provided at one end of the feed column 41 away from the telescopic head of the feed cylinder 40. After the metal ingot enters the feed pipe, the feed house moves in the direction of the metal ingot, and the accommodating groove wraps the terminal at the end of the metal ingot. In this way, the end face of the metal ingot with the terminal can be tightly attached to the end face of the feed house, thereby maintaining the stability of the metal ingot feeding process.

[0039] A buffer pad 22 is provided at the bottom of the inner cavity of the feeding tube, and the top of the buffer pad 22 is a curved surface. The axial length of the buffer pad 22 is greater than the axial length of the feeding port of the feeding tube. When the buffer pad 22 is not deformed, the top curved surface of the buffer pad 22 is coplanar with the curved surface of the inner wall of the feeding tube. The buffer pad 22 can be made of high-temperature resistant Teflon material. When the metal ingot falls into the feeding tube, the buffer pad 22 can buffer the impact load of the metal ingot.

[0040] The feeding port of the waiting bin 30 is arranged on the side of one end of the waiting bin 30 away from the feeding pipe 20. The feeding port of the waiting bin 30 is provided with a heating pipe 35. The heating pipe 35 can be made of insulating ceramic material. The heating pipe 35 is embedded with a heating coil 36. The internal space of the heating pipe 35 is connected with the internal space of the waiting bin 30. The height of the heating pipe 35 close to the end of the waiting bin 30 is higher than the height of the end of the heating pipe 35 away from the waiting bin 30. The inner circle diameter of the heating coil 36 is larger than the diameter of the metal ingot. In this way, the metal ingot entering the waiting bin needs to pass through the heating coil 36 first. 6. The heating coil 36 induces eddy current chaos inside the metal ingot to heat up the metal ingot, and the metal ingot enters the waiting bin 30 only after it is heated up. During the waiting time after the metal ingot enters the waiting bin 30, the internal temperature of the metal ingot is homogenized, ensuring that the internal temperature of the metal ingot is uniform when entering the pressing chamber 10. In this way, the operator can heat the metal ingot during the process of loading the metal ingot. The heating and temperature homogenization of the metal ingot does not occupy the waiting time of the pressing chamber 10, thereby improving the overall pressing efficiency. When in use, the heating coil 36 can be connected to the mains through a converter for use.

[0041] In some possible implementations of the embodiments of the present application, the pressing chamber 10 is installed on a reference plane, and the cylinder bases of the waiting bin 30, the feeding pipe 20, and the feeding cylinder 40 are all fixedly mounted on the reference plane by brackets, so that the positions of the cylinder bases of the waiting bin 30, the feeding pipe 20, and the feeding cylinder 40 in the working state remain relatively fixed with the position of the pressing chamber 10.

[0042] In some possible implementations of the embodiments of the present application, the driving device 34 can be a reduction motor, and the pressing chamber 10, the feeding cylinder 40 and the driving device 34 are all electrically driven. In actual use, the pressing chamber 10, the feeding cylinder 40 and the driving device 34 can obtain electrical energy by connecting to the mains.

[0043] In some possible implementations of the embodiments of the present application, the opening or closing of the pressing chamber 10, the feed cylinder 40 and the drive device 34 can be controlled one by one by the operator, or a controller can be provided to connect the pressing chamber 10, the feed cylinder 40 and the drive device 34 to the controller by signal, so that the pressing chamber 10, the feed cylinder 40 and the drive device 34 can be operated in coordination through the controller.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
