Description

Technical Field

[0001] The utility model belongs to the technical field of tin material forming and processing, in particular to a rotary tin material pouring mechanism. Background Art

[0002] In the prior art, tin wire is typically produced by stretching. This involves first casting molten tin into bars or blocks, then stretching these larger diameter bars or blocks through a wire drawing machine into tin wire of varying specifications. Currently, molten tin is scooped into a cup and poured into the mold cavity. This requires workers to move frequently to scoop and pour the molten tin, resulting in low casting efficiency. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a rotary tin material pouring mechanism which has high operating efficiency and is convenient for controlling the flow rate of tin liquid.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a rotary tin material pouring mechanism, including an insulation pouring box, a movable pouring box, an operating rod, a rotating shaft, a column, a base and a tension spring, the column is fixedly mounted on the base, the insulation pouring box is rotatably mounted on the column, the operating rod is fixedly mounted on the outer end of the movable pouring box, the top surface and the right side surface of the movable pouring box have openings, the rotating shaft is fixedly mounted on the front and rear sides of the outer wall of the insulation pouring box, a shaft sleeve is provided on the inner wall of the movable pouring box, the movable pouring box is rotatably mounted on the rotating shaft through the shaft sleeve, a feeding channel is provided on the bottom surface of the left end of the insulation pouring box, a pouring channel is provided on the bottom surface of the left end of the movable pouring box, a blocking block for sealing the bottom opening of the feeding channel is provided on the bottom wall of the movable pouring box, the bottom surface of the feeding channel is set as an inclined structure, and the upper and lower ends of the tension spring are respectively fixedly connected to the outer walls of the insulation pouring box and the movable pouring box.

[0005] Preferably, the limit angle of the movable pouring box's counterclockwise rotation from a horizontal state is 5°-10°.

[0006] Preferably, a non-slip rubber sleeve is fixedly mounted on the outer end of the operating rod.

[0007] Preferably, the base is provided with through holes in a circular array.

[0008] Compared with the prior art, the benefits of the present invention are: this mechanism can load a large amount of molten tin into the insulation pouring box at one time for standby use, and then rotate the combination of the rotating insulation pouring box and the movable pouring box to the position directly above each mold cavity for pouring operation, which has the advantages of convenient operation and high pouring efficiency. When the combination of the insulation pouring box and the movable pouring box is rotated again, the movable pouring box is reset under the action of the tension spring, and the blocking block blocks the feed channel or reduces its flow rate, thereby avoiding excessive overflow of the molten tin in the movable pouring box due to excessive flow in the feed channel when it rotates to the next station.

[0013] The present invention is described in detail below in conjunction with specific embodiments:

[0014] like Figures 1 to 3 The rotary tin material pouring mechanism shown in the figure includes an insulation pouring box 1, a movable pouring box 2, an operating rod 3, a rotating shaft 4, a column 5, a base 6 and a tension spring 7. The column 5 is fixedly mounted on the base 6, and the insulation pouring box 1 is rotatably mounted on the column 5. The operating rod 3 is fixedly mounted on the outer end of the movable pouring box 2. The top and right side surfaces of the movable pouring box 2 have openings. The rotating shaft 4 is fixedly mounted on the front and rear sides of the outer wall of the insulation pouring box 1. A shaft sleeve is provided on the inner wall of the movable pouring box 2. The movable pouring box 2 is rotatably mounted on the rotating shaft 4 through the shaft sleeve. A feeding channel 11 is provided on the bottom surface of the left end of the insulation pouring box 1, and a pouring channel 21 is provided on the bottom surface of the left end of the movable pouring box 2. A blocking block 22 for blocking the bottom opening of the feeding channel 11 is provided on the bottom wall of the movable pouring box 2. The bottom surface of the feeding channel 11 is set as an inclined structure. The upper and lower ends of the tension spring 7 are respectively fixedly connected to the outer walls of the insulation pouring box 1 and the movable pouring box 2.

[0015] The limit angle of the movable pouring box 2 in counterclockwise rotation from the horizontal state is 6°, which prevents the movable pouring box 2 from rotating counterclockwise too much and causing the tin liquid to overflow. The counterclockwise rotation limit is achieved by the bottom of the opening on the right side of the movable pouring box 2 contacting the insulation pouring box 1.

[0016] The outer end of the operating rod 3 is fixedly sleeved with an anti-skid rubber sleeve 31, which can play the role of anti-skid and heat insulation.

[0017] The base 6 is provided with through holes in a circular array so that the base 6 can be fixed on the floor of a production workshop or a workbench by passing bolts through the through holes.

[0018] The mold table for forming tin material is provided with an arc-shaped structure in a coaxial position with the column 5. First, the high-temperature tin liquid is stored in the heat-insulating pouring box 1. Under the action of the tension of the tension spring 7, the movable pouring box 2 rotates clockwise around the rotating shaft 4 until the blocking block 22 contacts the bottom surface of the feeding channel 11 to block it. The operator controls the heat-insulating pouring box 1 and the movable pouring box 2 to rotate around the column 5 through the operating lever 3. When the pouring channel 21 of the movable pouring box 2 is located just above the mold cavity of the mold table, the rotation of the combination of the heat-insulating pouring box 1 and the movable pouring box 2 is stopped. The operator presses down the operating lever 3 to make the movable pouring box 2 overcome the tension of the tension spring 7 and rotate downward counterclockwise around the rotating shaft 4. The blocking block 22 releases the blocking effect of the feeding channel 11, and the tin liquid flows out of the feeding channel 11. The liquid flows from the channel 11 to the movable pouring box 2, and then is poured into the mold cavity of the mold table through the pouring channel 21. When the pouring of a mold cavity is completed, the operator lifts the operating lever 3 to make the movable pouring box 2 rotate clockwise and reset under the action of the tension of the tension spring 7. The blocking block 22 contacts the bottom surface of the feed channel 11 to block it. Even if the blocking block 22 cannot completely block the feed channel 11, it can reduce its flow rate. In this way, the diameter of the feed channel 11 can be set to a large diameter of 3-5 cm to prevent the tin liquid from cooling and blocking the feed channel 11, and to prevent the tin liquid from flowing quickly into the movable pouring box 2 and overflowing. The combination of the heat-insulating pouring box 1 and the movable pouring box 2 is rotated again to the position directly above the next mold cavity for pouring.
