Description

Technical Field

[0001] The invention relates to the field of casting equipment, in particular to lead alloy ingot casting and processing equipment. Background Art

[0002] Lead alloy ingot casting is the process of heating the lead alloy raw material to liquid state, then casting it into a mold, allowing it to cool and solidify into an ingot. The process generally includes preparing raw materials, smelting, casting, cooling, demolding, etc. When casting aluminum alloy raw materials, a chain is usually used to drive the mold to rotate in a cycle, and then the molten lead alloy raw material is automatically distributed to each mold through a diversion structure.

[0003] The existing diversion structure usually consists of a circular storage cavity and a power source. A plurality of discharge ports are opened on the side of the circular storage cavity along its circumference. When distributing the aluminum alloy raw materials, the power source drives the circular storage cavity to rotate, so that the rotation speed of the discharge port of the circular storage cavity is consistent with the movement speed of the mold, so that the aluminum alloy raw materials inside the circular storage cavity flow evenly through the discharge port to the inside of each mold.

[0004] Since the position of the circular storage cavity remains unchanged, the aluminum alloy raw material is always fed to a fixed position on the mold, and then the interior of the mold is filled with the fluidity of the aluminum alloy raw material itself. However, the aluminum alloy raw material begins to cool when it comes into contact with the mold with a lower temperature, which reduces the fluidity of the aluminum alloy raw material, making it impossible for the aluminum alloy raw material to be evenly distributed inside the mold, thereby affecting the strength of the aluminum alloy ingot. In addition, since the circular storage cavity drives the discharge port thereon to move with the mold by rotation, the height distance between the discharge port and the mold is always changing, resulting in inconsistent contact time between the aluminum alloy raw material flowing out of the circular storage cavity and the mold, further affecting the uniformity of the distribution of the aluminum alloy raw material inside the mold.

Detailed implementation manners

[0035] The embodiments of the present invention will be described in detail below. The described embodiments are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those not specified in the embodiments in terms of specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0036] Refer to Figure 1 and Figure 2 , a lead alloy ingot casting and processing device, including a U-shaped frame 1, a liquid distribution mechanism 2 for evenly distributing aluminum alloy raw materials into each mold is arranged on the U-shaped frame 1, an L-shaped plate 11 is fixedly installed in the middle at the rear side of the U-shaped frame 1, and an anti-blocking mechanism 3 for cleaning the liquid distribution mechanism 2 is arranged on the L-shaped plate 11.

[0037] When it is necessary to cast aluminum alloy raw materials on the mold, first start the liquid distribution mechanism 2 to move at the same speed as the mold. Then, the operator guides the aluminum alloy raw materials into the interior of the liquid distribution mechanism 2. Subsequently, the liquid distribution mechanism 2 starts to evenly distribute the aluminum alloy raw materials inside it and cast them into the mold. At the same time, the anti-blocking mechanism 3 cleans the liquid distribution mechanism 2 in real time to prevent the aluminum alloy raw materials from cooling and solidifying on the liquid distribution mechanism 2, ensuring the discharge amount of the liquid distribution mechanism 2.

[0038] It should be noted that the molds in this embodiment are fixedly installed on the conveyor chain in the prior art. By rotating the conveyor chain, a plurality of molds thereon are driven to move synchronously in a cycle, so that the molds pass through the lower part of the liquid distribution mechanism 2 in turn, thereby enabling the liquid distribution mechanism 2 to distribute the aluminum alloy raw materials into the molds.

[0039] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The liquid dispensing mechanism 2 includes a rotating shaft 21 rotatably arranged on the right side of the left vertical section of the shaped frame 1, and a material storage barrel 22 is fixedly installed on the right side of the rotating shaft 21. The material storage barrel 22 is located on the lower middle side of the horizontal section of the shaped frame 1. The material storage barrel 22 is a hollow structure, and through grooves 221 are opened on the material storage barrel 22 at equal intervals along its circumference. The through grooves 221 connect the inside of the material storage barrel 22 with the outside. A shielding plate 23 is slidably arranged on the through groove 221 along the left and right directions, and a discharge pipe 24 is inserted through the middle part of the shielding plate 23 along the radial sliding direction of the material storage barrel 22. An executive motor 4 is fixedly installed on the left upper part of the horizontal section of the shaped frame 1, and the executive motor 4 is connected to the rotating shaft 21 through a belt.

[0040] When it is necessary to cast the aluminum alloy raw material on the mold, the execution motor 4 is started to drive the rotating shaft 21 to rotate, the rotating shaft 21 drives the storage barrel 22 to rotate synchronously, and the storage barrel 22 drives the discharge pipe 24 to rotate synchronously through the shielding plate 23, so that the speed at which the discharge pipe 24 rotates around the storage barrel 22 is equal to the moving speed of the mold.

[0041] Continue reading Figure 1 , Figure 2 , Figure 3 and Figure 4 A feeding hopper 5 is fixedly installed on the upper right side of the right vertical section of the U-shaped frame 1, and an L-shaped guide tube 51 is fixedly installed on the lower part of the feeding hopper 5. The horizontal section of the L-shaped guide tube 51 is rotated and inserted into the center position of the storage barrel 22.

[0042] When the storage barrel 22 starts to rotate, the operator guides the aluminum alloy raw material into the feeding hopper 5, so that the aluminum alloy raw material flows through the feeding hopper 5 and the L-shaped conduit 51 and is temporarily stored in the storage barrel 22, and the liquid level of the aluminum alloy raw material inside the storage barrel 22 is maintained at a fixed height.

[0043] See also Figure 3 , Figure 4 and Figure 5 The part of the L-shaped conduit 51 located inside the material storage barrel 22 is fixedly installed with an arc-shaped baffle 511 arranged symmetrically front and back through a support plate. The outer side surface of the arc-shaped baffle 511 fits on the inner side surface of the material storage barrel 22, and the end of the discharge pipe 24 located inside the material storage barrel 22 has an arc-shaped structure that can fit tightly on the outer side surface of the arc-shaped baffle 511.

[0044] When the material storage barrel 22 drives the discharge pipe 24 to start rotating, the discharge pipe 24 located at the lower part of the material storage barrel 22 rotates from front to back until the ends of the discharge pipes 24 located inside the material storage barrel 22 on the front and rear sides of the material storage barrel 22 are attached to the outer surface of the arc baffle 511, so that the arc baffle 511 blocks the end of the discharge pipe 24 located inside the material storage barrel 22, thereby preventing the aluminum alloy raw material inside the material storage barrel 22 from splashing into the interior of the end of the discharge pipe 24 located inside the material storage barrel 22 when the end of the discharge pipe 24 located outside the material storage barrel 22 is not aligned with the mold, causing the aluminum alloy raw material to flow out along the discharge pipe 24 to the outside of the mold, resulting in waste of aluminum alloy raw material.

[0045] When the discharge pipe 24 rotates to the lower part of the front arc baffle 511, one end of the discharge pipe 24 located inside the storage barrel 22 is immersed in the aluminum alloy raw material inside the storage barrel 22, so that the aluminum alloy raw material inside the storage barrel 22 flows out to the outside of the storage barrel 22 through the discharge pipe 24 under the action of gravity. At this time, one end of the discharge pipe 24 located outside the storage barrel 22 corresponds to the left part of the upper side of the mold, so that the aluminum alloy raw material flows from the left part of the upper side of the mold to its interior.

[0046] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 The liquid dispensing mechanism 2 also includes a push plate assembly 25 that pushes the shielding plate 23 rotated to the lower part of the storage barrel 22 to the right at a uniform speed. The push plate assembly 25 includes a follower rod 251 fixedly installed on the left outer side of the shielding plate 23. A fixed tube 252 is fixedly installed on the right side of the vertical section of the left part of the shaped frame 1. A guide rail groove 253 is opened on the inner side of the fixed tube 252. The follower rod 251 extends into the guide rail groove 253 and moves along its trajectory.

[0047] See also Figure 3 and Figure 7 The guide rail groove 253 is a closed-loop structure as a whole. The lower side of the guide rail groove 253 is a spiral section structure from the front left side to the rear right side, the right side of the guide rail groove 253 is an arc section structure from bottom to top, the upper side of the guide rail groove 253 is a spiral section structure from the rear right side to the front left side, and the left side of the guide rail groove 253 is an arc section structure from top to bottom.

[0048] See also Figure 2 , Figure 3 and Figure 8 In the process of the discharge pipe 24 moving from the left end of the through slot 221 to the right end of the through slot 221, the shielding plate 23 at the corresponding position changes from its right side surface being flush with the right side surface of the storage barrel 22 to its left side surface being flush with the left side surface of the storage barrel 22.

[0049] When the material storage barrel 22 drives the shielding plate 23 to rotate synchronously, the shielding plate 23 drives the follower rod 251 thereon to move along the guide groove 253 of the fixed tube 252, so that the guide groove 253 guides and controls the left and right position of the shielding plate 23 through the follower rod 251.

[0050] When the discharge pipe 24 rotates to the lower part of the arc-shaped baffle 511 on the front side, the shielding plate 23 connected thereto drives the follower rod 251 thereon to move to the spiral section structure on the lower side of the guide rail groove 253. Thereafter, the discharge pipe 24 and the shielding plate 23 rotate toward the rear side while the guide rail groove 253 pushes the follower rod 251 to the right side, so that the follower rod 251 drives the discharge pipe 24 to move to the right synchronously through the shielding plate 23, thereby causing the discharge pipe 24 to distribute the aluminum alloy raw material from left to right inside the mold, thereby increasing the uniformity of the aluminum alloy raw material inside the mold.

[0051] See also Figure 1 , Figure 2 , Figure 8 and Fig. 9 The liquid dispensing mechanism 2 also includes a distance-adjusting component 26 for controlling the length of the discharge pipe 24 that rotates to the lower part of the storage barrel 22 and extends to the outside of the storage barrel 22. The distance-adjusting component 26 includes two guide groove rings 261 that are fixedly installed at the lower part of the horizontal section of the shaped frame 1 and are arranged symmetrically on the left and right sides. A rectangular frame 262 corresponding to the shielding plate 23 is commonly provided between the two guide groove rings 261. The rectangular frame 262 cooperates with the notches of the guide groove rings 261 through the raised columns at its left and right ends. A square plate 263 is fixedly installed on the outer side of the end of the discharge pipe 24 away from the storage barrel 22. The square plate 263 is slidably connected to the rectangular frame 262 at the corresponding position along the left and right directions. The upper part of the guide groove ring 261 is an arc-shaped structure coaxial with the storage barrel 22, and the lower side of the guide groove ring 261 is a horizontal structure.

[0052] When the discharge pipe 24 starts to rotate, the discharge pipe 24 pushes the rectangular frame 262 at the corresponding position to move synchronously through the square plate 263 thereon, so that the rectangular frame 262 moves along the trajectory of the guide groove ring 261. When the discharge pipe 24 rotates to the lower part of the arc-shaped baffle 511 on the front side, the discharge pipe 24 drives the raised column of the rectangular frame 262 at the corresponding position to move to the front of the horizontal structure of the guide groove ring 261.

[0053] When the discharge pipe 24 starts to rotate from front to back, the discharge pipe 24 drives the rectangular frame 262 at the corresponding position to move horizontally backward along the horizontal structure of the guide groove ring 261, so that the rectangular frame 262 drives the end of the discharge pipe 24 away from the storage barrel 22 to move horizontally backward through the square plate 263. As a result, when the discharge pipe 24 casts the aluminum alloy raw material on the mold, the end of the discharge pipe 24 away from the storage barrel 22 always maintains the same height distance from the mold, thereby making the contact time between the aluminum alloy raw material and the mold consistent, further increasing the strength of the aluminum alloy ingot.

[0054] When the discharge pipe 24 rotates to the lower part of the arc-shaped baffle 511 on the rear side, the discharge pipe 24 drives the raised column of the rectangular frame 262 at the corresponding position to move to the rear of the horizontal structure of the guide groove ring 261. At the same time, the shielding plate 23 drives the discharge pipe 24 to move to the right end of the through groove 221, and the shielding plate 23 drives the follower rod 251 thereon to move to the arc-shaped section structure on the right side of the guide groove 253.

[0055] Continue to rotate the discharge pipe 24 so that the end of the discharge pipe 24 located inside the storage barrel 22 moves out of the aluminum alloy raw material inside the storage barrel 22, and at the same time, the end of the discharge pipe 24 located inside the storage barrel 22 moves to the outer surface of the arc-shaped baffle 511 attached to the rear side, so that the arc-shaped baffle 511 blocks the discharge pipe 24 again.

[0056] At the same time, the shielding plate 23 drives the discharge pipe 24 to continue to rotate upward at the right side of the guide groove 253 , and the rectangular frame 262 drives the discharge pipe 24 to rotate along the circumferential direction of the storage barrel 22 along the arc-shaped structure of the guide groove ring 261 .

[0057] See also Figure 1 , Figure 2 , Fig.10 and Fig.11 The anti-blocking mechanism 3 includes an arc plate 31 fixedly installed on the front side of the vertical section of the L-shaped plate 11, the axis of the arc plate 31 coincides with the axis of the storage barrel 22, a moving block 32 is provided inside the arc plate 31 to slide along its arc track, a tension spring is provided between the moving block 32 and the lower part of the arc plate 31, an insertion column 33 is inserted inside the moving block 32, a spiral scraper 34 is fixedly installed in front of the insertion column 33, and the front part of the spiral scraper 34 is a conical structure.

[0058] See also Figure 2 , Fig.10 and Fig.11 A number one gear 35 is rotatably provided on the rear side of the moving block 32, an arc-shaped tooth segment 36 meshing with the number one gear 35 is fixedly installed on the left side of the rear of the arc plate 31, and the number one gear 35 is slidably connected with the insertion column 33. An L-shaped follower plate 37 is fixedly installed on the upper end of the moving block 32, and an electric push rod 38 is fixedly installed on the rear side of the follower plate 37. The telescopic section of the electric push rod 38 is rotatably connected with the insertion column 33. A support plate 39 is slidably provided on the upper part of the moving block 32 along a direction parallel to the axial direction of the insertion column 33, and a coil spring is provided between the support plate 39 and the moving block 32. A triangular block 391 is fixedly installed on the rear side of the upper part of the support plate 39, and a pushing block 392 for pushing the triangular block 391 backward is fixedly installed on the lower side of the top of the arc plate 31.

[0059] When the discharge pipe 24 rotates to the lower part of the arc-shaped baffle 511 on the rear side, the discharge pipe 24 contacts the lower side surface of the abutment plate 39, so that the discharge pipe 24 drives the moving block 32 to rotate upward along the trajectory of the arc plate 31 by pushing the abutment plate 39, and stretches the tension spring, so that the moving block 32 and the discharge pipe 24 move synchronously, and at this time the discharge pipe 24 is arranged coaxially with the insertion column 33.

[0060] Then, the telescopic section of the electric push rod 38 is extended to drive the insertion column 33 to move forward, and the insertion column 33 drives the spiral scraper 34 on its front side to be inserted into the interior of the discharge pipe 24, and the outer side of the spiral scraper 34 is attached to the inner side surface of the discharge pipe 24. The moving block 32 rotates upward and drives the No. 1 gear 35 to move synchronously, so that the No. 1 gear 35 rotates through the engagement with the arc-shaped tooth segment 36, so that the No. 1 gear 35 drives the spiral scraper 34 to rotate synchronously through the insertion column 33. The spiral scraper 34 scrapes the aluminum alloy raw material on the inner side surface of the discharge pipe 24 and pushes the aluminum alloy raw material toward the storage barrel 22.

[0061] Then, the telescopic section of the electric push rod 38 is retracted to drive the insertion column 33 to return to its initial position backward. When the abutment plate 39 drives the triangular block 391 thereon to contact the pushing block 392, the pushing block 392 pushes the triangular block 391 backward, so that the triangular block 391 drives the abutment plate 39 to move backward until it no longer blocks the discharge pipe 24. Then the tension spring pulls the moving block 32 to return to its initial position through its own elastic force, and then the coil spring pushes the abutment plate 39 to return to its initial position.

[0062] When the discharge pipe 24 rotates to the upper part of the arc-shaped baffle 511 on the rear side, the aluminum alloy raw material scraped off by the spiral scraper 34 inside the discharge pipe 24 flows back to the inside of the storage barrel 22 under the action of gravity, further avoiding the waste of aluminum alloy raw material. At this time, the shielding plate 23 drives the follower rod 251 thereon to move to the spiral section structure on the upper side of the guide rail groove 253, so that the follower rod 251 moves along the spiral section structure on the upper side of the guide rail groove 253, and then the shielding plate 23 drives the discharge pipe 24 to move from the right side of the through groove 221 to its initial position on the left side.

[0063] The present invention also includes the following steps when performing split casting on aluminum alloy raw materials: the first step is to start the execution motor 4 to drive the storage barrel 22 to rotate, so that the speed at which the discharge pipe 24 rotates around the storage barrel 22 is equal to the moving speed of the mold.

[0064] In the second step, the operator guides the aluminum alloy raw material into the feeding hopper 5, so that the aluminum alloy raw material flows through the feeding hopper 5 and the L-shaped conduit 51 and is temporarily stored in the storage barrel 22, and the liquid level of the aluminum alloy raw material in the storage barrel 22 is maintained at a fixed height.

[0065] In the third step, when the discharge pipe 24 rotates to the lower part of the front arc-shaped baffle 511, the guide groove 253 pushes the follower rod 251 to the right, so that the follower rod 251 drives the discharge pipe 24 to move to the right synchronously through the shielding plate 23, so that the discharge pipe 24 distributes the aluminum alloy raw material from left to right inside the mold, thereby increasing the uniformity of the aluminum alloy raw material inside the mold.

[0066] In the fourth step, the discharge pipe 24 drives the rectangular frame 262 at the corresponding position to move backward horizontally along the horizontal structure of the guide groove ring 261, so that during casting, the end of the discharge pipe 24 away from the storage barrel 22 always maintains the same height distance from the mold, thereby making the contact time between the aluminum alloy raw material and the mold consistent, further increasing the strength of the aluminum alloy ingot.

[0067] In the fifth step, the discharge pipe 24 drives the moving block 32 to rotate synchronously through the abutment plate 39, and the telescopic section of the electric push rod 38 is extended to drive the spiral scraper 34 to be inserted into the interior of the discharge pipe 24, so that the spiral scraper 34 scrapes the aluminum alloy raw material on the inner side surface of the discharge pipe 24 and pushes the aluminum alloy raw material toward the storage barrel 22.

[0068] In the sixth step, the telescopic section of the electric push rod 38 is retracted to drive the insertion column 33 to return to the initial position backward, and the pushing block 392 pushes the triangular block 391 backward to drive the abutment plate 39 to no longer block the discharge pipe 24, and then the tension spring pulls the moving block 32 to return to the initial position through its own elastic force, and then the coil spring pushes the abutment plate 39 to return to the initial position.

[0069] In the seventh step, the discharge pipe 24 rotates to the upper part of the arc-shaped baffle 511 on the rear side, and the aluminum alloy raw material scraped off by the spiral scraper 34 inside the discharge pipe 24 flows back to the inside of the storage barrel 22 under the action of gravity, and then the follower rod 251 moves along the spiral section structure on the upper side of the guide groove 253, so that the shielding plate 23 drives the discharge pipe 24 to move from the right side of the through groove 221 to its initial position on the left side.
