Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing equipment, in particular to a rod casting machine. Background Art

[0002] Before the aluminum profile is formed in the extruder, the aluminum liquid needs to be formed into an aluminum rod in the rod casting machine. The existing rod casting device is to place the forming mold, cooling mechanism and fixed bracket in the well, and liquid is provided in the well. During the rod casting process, the liquid discharge mechanism injects aluminum liquid into the forming mold, and the cooling mechanism cools the aluminum liquid to form a solid aluminum rod. The solid aluminum rod is located on the fixed bracket. At this time, the fixed bracket sinks to empty the forming mold to continue to form a fixed aluminum rod. Such a cycle can form a formed aluminum rod. However, the solid aluminum rod is located on the fixed bracket, and the fixed bracket is pulled by a steel wire rope. When the solid aluminum rod is formed to a certain length, the fixed bracket will swing in the well, making the surface of the formed aluminum rod not smooth enough, and its central axis is not in a straight line. When this aluminum rod is extruded in the extruder, it is easy to get stuck in the extruder and damage the extruder. Based on this, it is necessary to propose a new type of rod casting machine to solve the above problems.

[0003] The present invention provides a rod casting machine, wherein a limiting device is provided between a shaft and a fixed bracket, so that the fixed bracket can only descend vertically and will not shake on a plane, thereby ensuring that the surface of the formed aluminum rod is smooth and that its central axis is in a straight line, thereby preventing damage to the extruder. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a rod casting machine, in which a limiting device is provided between the shaft and the fixed bracket, so that the fixed bracket can only descend vertically and will not shake on the plane, thereby ensuring that the surface of the formed aluminum rod is smooth and its central axis is in a straight line to prevent damage to the extruder.

The limiting rail is distributed along the entire length of the well. The limiting block matches the limiting rail in shape, size, position and number. The limiting rail extends into the limiting block to prevent the fixed bracket from shifting in position inside the well.

[0007] Preferably, the shaft is in the shape of a square column, and a limit rail installation position is respectively provided on the four side walls;

[0008] The fixing bracket is in a square shape and is parallel to the forming mold.

[0009] Preferably, the fixed bracket is provided with a lifting mechanism installation position and a limit block installation position;

[0012] Preferably, the molding die comprises at least one molding hole;

[0013] The area of ​​the forming mold is smaller than or equal to the area of ​​the fixing bracket.

[0014] Preferably, the cooling mechanism comprises a container for containing a cooling liquid and a nozzle connected to the container, wherein the nozzle is located around the forming mold, and the cooling liquid is sprayed onto the forming mold through the nozzle.

[0015] Preferably, the lifting mechanism comprises a fixing fixture, a steel wire rope connected to the fixing fixture, and a driving structure connected to the steel wire rope, and the fixing fixture is fixed to the lifting mechanism installation position on the fixing bracket.

[0018] Preferably, the limiting block comprises a first limiting block and a second limiting block arranged opposite to the first limiting block, and the first limiting block and the second limiting block are respectively located on two sides of the limiting track.

[0019] Preferably, the limiting track is in an I-shaped structure, and a protruding guide rail is provided on its end surface;

[0020] The limiting rail and the limiting block are made of H13 steel.

[0021] The implementation of the present invention has the following beneficial effects:

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0028] like Figure 1-2 As shown, an embodiment of the present invention provides a rod casting machine, comprising a shaft 1, a fixed bracket 2 located inside the shaft 1, a forming mold 3 located above the fixed bracket 2, a liquid discharge mechanism (not shown in the figure) connected to the forming mold 3, a cooling mechanism 4 connected to the forming mold 3, a lifting mechanism 5 connected to the fixed bracket 2, and a limiting mechanism 6 located between the shaft 1 and the fixed bracket 2;

[0029] The limiting mechanism 6 includes a limiting rail 61 located on the inner wall of the shaft 1 and a limiting block 62 located on the side wall of the fixed bracket 2. The limiting rail 61 is distributed in the entire length direction of the shaft 1 and is in an I-shaped structure. The two end faces of the limiting rail of the I-shaped structure are provided with protruding guide rails. The limiting block 62 matches the shape, size, position and number of the limiting rail 61. The protruding guide rail of the limiting rail 61 extends into the inside of the limiting block 62 to prevent the fixed bracket 2 from shifting in the position inside the shaft 1.

[0030] Specifically, the limiting rail and the limiting block of the limiting mechanism are both made of H13 steel. Since H13 steel has high mechanical properties and good wear resistance and corrosion resistance, in order to alleviate the rigid friction between the limiting rail and the limiting block, rubber is also provided on the contact surface between the limiting block and the limiting rail, which is convenient for alleviating the friction between the limiting block and the limiting rail and improving the service life of the rod casting machine.

[0031] The shaft 1 is used to accommodate the fixed bracket 2, the forming mold 3 and the formed aluminum rod. Since the longer the length of the aluminum rod is formed, the heavier it is, in order to reduce the traction force of the lifting mechanism 5 on the fixed bracket 2, the shaft 1 is filled with liquid, so that the aluminum rod and the fixed bracket 2 can reduce the traction force of the lifting mechanism 5 due to the buoyancy of the liquid; on the other hand, the liquid inside the shaft 1 can also quickly cool down the formed aluminum rod to prevent the temperature of the aluminum rod removed from the fixed bracket 2 from being too high, which will cause inconvenience to production and operation.

[0032] The shape of the shaft 1 is cylindrical or square columnar. In the present embodiment, the shaft 1 is square columnar. A limiting rail installation position is respectively provided on the four side walls of the shaft 1 for installing the limiting rail 61 to realize the limiting of the fixing bracket 2.

[0033] The fixed bracket 2 is located inside the well 1 and is used to hold the solid aluminum rod to ensure that the aluminum rod can be continuously formed to form a complete aluminum rod. The shape of the fixed bracket 2 matches the shape of the well 1, and its specific shape is a square, and it is parallel to the forming mold 3.

[0034] In order to realize the lifting and limiting of the fixed bracket 2, a lifting mechanism installation position and a limit block installation position are provided on the fixed bracket 2, wherein the lifting mechanism installation position is located at the four corners of the fixed bracket 2 to ensure that the fixed bracket 2 can rise or fall smoothly under the traction force of the lifting mechanism 5; the limit block installation position is located on the side wall of the fixed bracket 2, which is arranged opposite to the limit track installation position to realize the limiting of the fixed bracket 2.

[0035] The forming mold 3 is used to contain aluminum liquid, so that the aluminum liquid is quickly cooled inside the forming mold 3 to form a solid aluminum rod, and it includes at least one forming hole 31. The shape and size of the forming hole 31 are selected according to the shape and size of the aluminum rod to be formed. The forming mold 3 is located directly above the fixed bracket 2, and its area is less than or equal to the area of ​​the fixed bracket 2, ensuring that all aluminum rods formed by the forming mold 3 are supported by the fixed bracket 2, further ensuring that the aluminum rod forming can be completed smoothly.

[0036] The liquid discharge mechanism is connected to the forming mold 3, and injects aluminum liquid into the forming hole 31. The specific parameters such as the aluminum liquid injection speed and composition are selected according to the actual requirements of the aluminum rod. This technical feature is a conventional technical feature in this field and will not be repeated here.

[0037] The cooling mechanism 4 is connected to the forming mold 3 and is used to cool the forming mold 3 and the aluminum liquid therein, so that the aluminum liquid inside the forming mold 3 can be quickly cooled to form a solid aluminum rod. Specifically, the cooling mechanism 4 is a spray cooling mechanism, which includes a container for containing coolant and a nozzle connected to the container, the nozzle is located around the forming mold, and the coolant is sprayed on the forming mold through the nozzle, so that the aluminum liquid inside the forming hole can be quickly cooled to form a solid aluminum rod.

[0038] The lifting mechanism 5 is connected to the fixed bracket 2 and is used to realize the lifting and lowering of the fixed bracket 2. It includes a fixing clamp 51, a steel wire rope 52 connected to the fixing clamp 51, and a driving structure 53 connected to the steel wire rope 52. The fixing clamp 51 is fixed to the lifting mechanism installation position on the fixed bracket 2 to realize the connection between the lifting mechanism 5 and the fixed bracket 2. The steel wire rope 52 connects the fixing clamp 51 and the driving structure 53. During operation, the driving structure 53 moves to drive the steel wire rope 52 to tighten and relax. The fixing clamp 51 follows the steel wire rope 52 to rise or fall, thereby realizing the lifting and lowering movement of the fixed bracket 2.

[0039] It should be noted here that fixing clamps 51 are provided on the four corners of the fixing bracket 2, and the driving structure 53 drives the four fixing clamps 51 to rise or fall simultaneously through the wire rope 52, ensuring that the aluminum rod can rise or fall smoothly on the fixing bracket 2 to prevent damage to the aluminum rod.

[0040] like Figure 2 and 3As shown, the limiting mechanism 6 includes a limiting rail 61 located on the inner wall of the shaft 1 and a limiting block 62 located on the side wall of the fixed bracket 2. The limiting rail 61 is distributed in the entire length direction of the shaft 1 and is installed at the limiting rail installation position. The limiting rail 61 is parallel to the rising or falling line of the fixed bracket 2, ensuring that when the limiting rail 61 extends into the limiting block 62, the fixed bracket 2 can rise or fall smoothly.

[0041] The shape, size, position and number of the limit block 62 match those of the limit track 61, and include a first limit block 621 and a second limit block 622 arranged opposite to the first limit block 621, wherein the first limit block 621 and the second limit block 622 are respectively located on both sides of the limit track 61, that is, the first limit block 621 and the second limit block 622 hold the limit track 61, and when the fixed bracket 2 moves, the limit block 62 slides on the limit track 61, and prevents the position deviation and lateral displacement of the fixed bracket 2 without affecting the up and down movement of the fixed bracket 2, and ensures that the fixed bracket 2 moves linearly in the vertical direction, thereby avoiding the bending of the aluminum rod due to the position deviation and lateral displacement of the fixed bracket 2, thereby improving the quality of the aluminum rod and extending the service life of the extruder.

[0042] When the rod casting machine provided by the present invention is working, the discharge mechanism injects aluminum liquid into the forming hole of the forming mold 3, and the nozzle of the cooling mechanism 4 sprays cooling liquid onto the forming mold 3. The temperature of the aluminum liquid drops rapidly to form a solid aluminum rod. The lifting mechanism 5 drives the fixed bracket 2 to descend, and the solid aluminum rod follows the fixed bracket 2 to descend. After the solid aluminum rod leaves the forming hole 31, the discharge mechanism continues to inject aluminum liquid, and the cycle is repeated to complete the casting of the aluminum rod.

[0043] During the descent of the fixed bracket 2 pulled by the wire rope 52, the fixed bracket 2 will be offset in the plane due to the flow of liquid inside the well or the influence of other forces. As a result, the central axis of the already formed aluminum rod and the aluminum rod formed after the offset of the fixed bracket 2 are not in a straight line, resulting in an uneven surface of the aluminum rod, resulting in an unqualified aluminum rod. The present invention avoids the positional offset of the fixed bracket 2 through the limiting mechanism 6, and does not affect the rising or falling action of the fixed bracket 2, thereby ensuring that the surface of the produced aluminum rod is flat and the central axis is on the same straight line.

[0044] The implementation of the present invention has the following beneficial effects:

[0045] 1. The rod casting machine provided by the present invention prevents the position deviation and lateral displacement of the fixed bracket without affecting the up and down movement of the fixed bracket through the setting of the limiting mechanism, ensures the linear movement of the fixed bracket in the vertical direction, avoids the bending of the aluminum rod due to the position deviation and lateral displacement of the fixed bracket, thereby improving the quality of the aluminum rod and extending the service life of the extruder.

[0046] 2. In order to reduce the traction force of the lifting mechanism on the fixed bracket, the rod casting machine provided by the present invention is filled with liquid inside the well, so that the aluminum rod and the fixed bracket can reduce the traction force of the lifting mechanism due to the buoyancy of the liquid; on the other hand, the liquid inside the well can also quickly cool down the formed aluminum rod, preventing the aluminum rod removed from the fixed bracket from having too high a temperature, which causes inconvenience to production and operation.

[0047] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
