Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting equipment technology, and in particular to a manual quantitative pouring ladle and casting equipment. Background Technology
[0002] Currently in the casting field, due to the special nature of the process and / or the structure of the equipment and tooling, some castings cannot be automatically poured by robots and still require manual pouring by scooping molten metal from crucibles or ladles using a ladle.
[0003] When workers manually scoop molten metal, the weight or volume of the molten metal scooped each time can only be estimated based on experience, resulting in inaccurate scooping amounts. If too much molten metal is scooped, the remaining molten metal can only be poured into the ingot mold, resulting in material waste. Although it can be remelted, it still consumes a certain amount of energy. If too little molten metal is scooped, a second pouring is required, which prolongs the product pouring time, not only reducing work efficiency but also making the product prone to quality problems.
[0004] Therefore, the above problems urgently need to be solved. Utility Model Content
[0005] The purpose of this invention is to provide a manual quantitative pouring ladle and casting equipment, so that workers can scoop out molten metal in a quantitative manner, thereby reducing the waste of materials and energy, improving the efficiency of manual pouring, and improving the quality of products.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A manual quantitative pouring ladle includes a ladle body with a gate. The inner wall of the ladle body is provided with scale lines. The length direction of the scale lines is perpendicular to the depth direction of the ladle body. The scale lines protrude from or are recessed into the inner wall of the ladle body. The scale lines are offset from the gate.
[0008] Preferably, the scale line is located on the inner wall of the ladle body, opposite to the gate.
[0009] Preferably, multiple scale lines are provided along the depth direction of the ladle body.
[0010] Preferably, the ladle body is shaped like a frustum or a cylinder, and the central angle corresponding to the length of the scale line along the circumference of the ladle body is greater than or equal to 30°.
[0011] Preferably, the central angle corresponding to the length of the scale line is 45°.
[0012] Preferably, a scale strip is welded to the inner wall of the ladle body so that the scale lines are formed on the inner wall of the ladle body; or,
[0013] The inner wall of the ladle body is provided with a scale groove so that the scale line is formed on the inner wall of the ladle body.
[0014] Preferably, the inner wall of the ladle body is provided with scale markings corresponding to the scale lines.
[0015] Preferably, the inner wall of the ladle body is welded with lettering so that the scale markings are formed on the inner wall of the ladle body; or,
[0016] The font is engraved on the inner wall of the ladle body so that the scale markings are formed on the inner wall of the ladle body.
[0017] Preferably, a handle is connected to the ladle body.
[0018] Casting equipment, including furnaces and manual quantitative pouring ladles.
[0019] The beneficial effects of this utility model are:
[0020] This invention relates to a manual quantitative pouring ladle. By setting scale lines that protrude from or are recessed into the inner wall of the ladle body, the physical shape of the inner wall of the ladle body is altered. This changes the way light is reflected and scattered on the inner wall of the ladle body, improving the visibility of the scale lines. In other words, the scale lines are easier for the eye to spot. Each time the worker scoops molten metal, they can refer to the scale lines to accurately control the weight or volume of the molten metal, thereby reducing material and energy waste, improving the efficiency of manual pouring, and enhancing product quality.
[0021] In addition, because the scale lines are set off from the gate, the path of the molten metal flowing out of the ladle body is offset from the scale lines. This not only reduces the flow resistance of the molten metal, but also prevents the turbulence or eddies caused by the protruding scale lines, as well as the air bubbles mixed into the molten metal at the recessed scale lines, which helps to improve the quality of the casting.

[0030] The following reference Figures 1 to 2 The present invention describes the manual quantitative pouring ladle and casting equipment provided by this utility model.
[0031] The casting equipment includes a furnace and a manual metering ladle. The furnace can be any type of existing furnace that melts solid metal raw materials into liquid metal. Workers can then use a manual metering ladle to scoop up the molten metal and perform the pouring operation.
[0032] Existing manual quantitative pouring ladles cannot accurately measure the amount of molten metal, often resulting in too much or too little molten metal. Too much leads to waste of materials and energy, while too little requires extending the pouring time and affecting efficiency. To enable workers to accurately measure the amount of molten metal, this embodiment also provides a manual quantitative pouring ladle. The specific structure of this manual quantitative pouring ladle is described below.
[0033] Reference Figure 1 and Figure 2 The artificial quantitative pouring ladle includes a pouring ladle body 1, which has a pouring gate 11. The inner wall of the pouring ladle body 1 is provided with a scale line 2. The length direction of the scale line 2 is perpendicular to the depth direction of the pouring ladle body 1, and the scale line 2 protrudes from the inner wall of the pouring ladle body 1.
[0034] As described above, since the scale line 2 protrudes from the inner wall of the ladle body 1, it changes the physical shape of the inner wall of the ladle body 1, altering the way light is reflected and scattered on the inner wall of the ladle body 1. This improves the visibility of the scale line 2, making it easier for the eye to spot, i.e., the scale line 2 is more prominent. This allows workers to easily refer to the scale line 2 to accurately control the weight of the molten metal each time they scoop it. It should be noted that in this embodiment, the scale line 2 is a scale indicating the volume of the molten metal, ultimately reducing material and energy waste, improving the efficiency of manual pouring, and enhancing product quality. In other embodiments, the scale line can also be a scale indicating the volume of the molten metal.
[0035] For example, in this embodiment, the ladle body 1 is shaped like a frustum, with its diameter gradually increasing from bottom to top. The top of the ladle body 1 has an opening, and the gate 11 is located at the top of the ladle body 1. In other embodiments, the ladle body 1 may also be shaped like a cylinder, a frustum, or a prism; the specific shape is not limited. The specific material of the ladle body 1 is selected according to the temperature of the molten metal, ensuring that the melting point of the material of the ladle body 1 is higher than the temperature of the molten metal.
[0036] Specifically, a graduated strip is welded to the inner wall of the ladle body 1, with a weld width of less than 1 mm. The graduated strip is arc-shaped, and its center coincides with the axis of the ladle body 1, allowing it to fit snugly against the inner wall of the ladle body 1, thus forming graduated lines 2. Fixing the graduated strip by welding makes it more secure, less prone to detaching from the ladle body 1, and does not affect the structural strength of the ladle body 1. The specific position of the graduated lines 2 can be determined by calculation based on the volume of the ladle body 1 and the density of the molten metal, or by experimentation.
[0037] In addition, multiple graduation lines 2 are provided along the depth direction of the ladle body 1. In this embodiment, three graduation lines are used as an example, which are 10kg, 8kg and 6kg graduation lines from top to bottom. This allows workers to accurately scoop different weights of molten metal, thereby improving the adaptability of manual quantitative ladle casting to meet the casting needs of products of different weights.
[0038] Optionally, in some other embodiments, a scale groove can be provided on the inner wall of the ladle body 1 to form a recessed scale line 2 on the inner wall of the ladle body 1.
[0039] Furthermore, the scale line 2 is offset from the gate 11, meaning the position of the scale line 2 is off-center from the position of the gate 11. Since the molten metal flows out through the gate 11 when the ladle body 1 pours out the molten metal, offsetting the scale line 2 from the gate 11 deviates from the flow path of the molten metal. This prevents the scale line 2 from interfering with the continuous flow of the molten metal, reducing flow resistance and minimizing the likelihood of turbulence or eddies, thereby improving casting efficiency and quality.
[0040] Preferably, in this embodiment, the scale line 2 is located on the inner wall of the ladle body 1 opposite to the gate 11. That is, the scale line 2 and the gate 11 are arranged radially along the ladle body 1, so that the scale line 2 is located on the inner wall of the ladle body 1 at the position furthest from the gate 11, which can further reduce interference with the molten metal. In addition, since the operator usually immerses the gate 11 in the molten metal when scooping it, setting the scale line 2 opposite to the gate 11 ensures that the scale line 2 is always above the liquid surface, making it convenient for the operator to refer to the scale line 2 when scooping the molten metal.
[0041] Furthermore, along the circumferential direction of the ladle body 1, the central angle corresponding to the length of the scale line 2 is θ, where θ is greater than or equal to 30°. This limits the minimum length of the scale line 2 to make it easy to observe. Preferably, in this embodiment, θ is 45°, which saves material while ensuring easy observation and also takes into account the convenience of production, i.e., facilitating the welding of the scale strip.
[0042] In addition, the inner wall of the ladle body 1 is provided with scale marks 3 corresponding to the scale lines 2, and one scale mark 3 is provided at one end of each scale line 2. Specifically, the inner wall of the ladle body 1 is engraved with numbers to form scale marks 3, that is, the scale marks 3 are formed by laser engraving, thereby improving the recognizability of the scale marks 3. In this embodiment, the distance H between the 10kg scale line 2 and the bottom of the ladle body 1 is 150mm, and the height of the numbers is greater than or equal to 3mm. In this embodiment, 3mm is used as an example to improve recognizability.
[0043] Optionally, in some other embodiments, the scale markings 3 may also be located above or below the scale lines 2, and one scale marking 3 may be provided at each end of each scale line 2, with no limitation on the specific position and number. Additionally, in some other embodiments, the scale markings 3 may be formed by welding numbers to the inner wall of the ladle body 1.
[0044] To facilitate pouring operations, a handle 4 is connected to the outer wall of the ladle body 1. The handle 4 is T-shaped and located in the middle between the gate 11 and the scale line 2. This allows workers to control the ladle body 1 using the handle 4. A reinforcing rib 41 is also connected between the handle 4 and the ladle body 1. The reinforcing rib 41 is triangular in shape, which can improve the connection strength between the handle 4 and the ladle body 1, thereby ensuring the stability of the handle 4 during operation.
