Description

Technical Field

[0001] The invention relates to the technical field of casting, and more particularly to a generator end cover casting machine. Background Art

[0002] In the casting process of the generator end cover, the casting machine is a key equipment, and its performance and safety are of vital importance. Traditional generator end cover casting machines usually use a piston to push the molten metal for feeding. However, in this feeding method, the molten metal often generates greater pressure and impact when it is squeezed by the piston. Since the feeding port design of the casting machine is often relatively open and lacks sufficient shielding and protection measures, this causes the molten metal to easily splash out from the feeding port when it is squeezed.

[0003] The splashing of molten metal will not only damage the equipment structure of the casting machine itself, such as corrosion and wear, reducing the service life of the equipment; more importantly, the splashing of high-temperature molten metal may also cause serious burns or even more serious injuries to the operators, posing a great threat to production safety. In order to solve the above problems, a generator end cover casting machine is proposed. Summary of the invention

DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0031] For examples, see Figure 1 - Fig.10 , a generator end cover casting machine, comprising a casting machine body 1, and a feeding mechanism 2 connected to a mold is provided on the casting machine body 1; The feeding mechanism 2 includes a feeding assembly 3 connected to the mold, a feeding hopper 4 arranged on the feeding assembly 3, and a covering sleeve 5 arranged on the feeding assembly 3; The feeding assembly 3 includes a molten metal feeding pipe 301 connected to the mold, a feeding port 302 opened at one end of the molten metal feeding pipe 301 away from the mold, and a driving member 6 arranged in the molten metal feeding pipe 301; The feed hopper 4 is disposed above the feeding port 302 and can move up and down. The covering sleeve 5 is movably sleeved on the outside of the molten metal feeding pipe 301, and the movably sleeved covering sleeve 5 is used to cover or open the feeding port 302. A movable clamping mechanism 7 is provided on the covering sleeve 5, and the movable clamping mechanism 7 is clamped with the driving member 6. A driving connecting rod 8 is provided on the circumferential side wall of the covering sleeve 5, and the covering sleeve 5 and the feeding hopper 4 are rotatably mounted on both ends of the driving connecting rod 8 respectively.

[0032] The casting machine body 1 is a horizontal cold chamber die casting machine, and the feeding mechanism 2 is connected to the generator end cover mold on the horizontal cold chamber die casting machine, so that after the mold is pressed and fitted, the feeding mechanism 2 transports the molten metal to the mold for cooling, thereby completing the casting.

[0033] Specifically, according to the molten metal volume required for the generator end cover casting, a certain amount of molten metal is taken by a quantitative spoon, and then the molten metal is poured into the feed hopper 4. At this time, the feed hopper 4 is plugged into the feeding port 302 of the molten metal feeding pipe 301, so that the molten metal enters the molten metal feeding pipe 301 through the feed hopper 4, and then the driving member 6 is started. The driving member 6 pushes the molten metal inside the molten metal feeding pipe 301 to move toward the mold, and drives the covering sleeve 5 to move in the metal through the movable clamping mechanism 7. When the covering sleeve 5 moves on the molten metal feeding pipe 301 and the covering sleeve 5 moves, the feeding hopper 4 is driven to move by the driving connecting rod 8, so that the feeding hopper 4 is separated from the feeding port 302. After the feeding hopper 4 is separated from the feeding port 302, the covering sleeve 5 is not blocked by the feeding hopper 4 and is pushed by the driving member 6 to shield the feeding port 302, thereby preventing the driving member 6 from squeezing and splashing the molten metal from the feeding port 302 due to the extrusion force when the driving member 6 moves in the molten metal feeding pipe 301, thereby causing personal injury.

[0034] A vertical plate 9 is welded on the circumferential side wall of the molten metal feeding pipe 301, and a strip groove 901 is opened on the vertical plate 9, and a slider 401 is slidably installed in the strip groove 901, and the slider 401 is in an I-shape; A connecting rod 402 is provided on the circumferential side wall of the feed hopper 4 , and the connecting rod 402 is welded to one end close to the vertical plate 9 and the slider 401 .

[0035] When the driving member 6 drives the covering sleeve 5 to move on the molten metal feeding pipe 301 through the movable clamping mechanism 7, the driving connecting rod 8 drives the feeding hopper 4 to move, and the feeding hopper 4 is restricted by the connecting rod 402 of the welding slider 401 and the strip groove 901 on the vertical plate 9, so that the feeding hopper 4 can only move up and down on the feeding port 302, so that when the molten metal is pushed and squeezed into the mold by the driving member 6 for forming, the feeding hopper 4 moves up and disengages from the feeding port 302, so that the covering sleeve 5 can move to block the feeding port 302, and when the driving member 6 is reset to cast the next generator end cover, the reset of the driving member 6 will drive the covering sleeve 5 to move and reset through the movable clamping mechanism 7, so that the feeding port 302 is opened, and the feeding hopper 4 is driven to move downward by the driving connecting rod 8, so that the lower end of the feeding hopper 4 can be inserted into the feeding port 302, so that when the subsequent molten metal is added to the feed hopper 4, the molten metal can enter the molten metal feeding pipe 301.

[0036] A solution cavity 303 and a guide cavity 304 are provided inside the molten metal feeding pipe 301; The driving member 6 includes an electric cylinder 601 fixedly mounted on the casting machine body 1, a telescopic rod 602 disposed on the electric cylinder 601, and a piston 603 disposed at one end of the telescopic rod 602 away from the electric cylinder 601; The piston 603 and the solution chamber 303 are movably matched, and the telescopic rod 602 and the guide chamber 304 are movably matched.

[0037] The movable clamping mechanism 7 and the telescopic rod 602 are matched and clamped. When the electric cylinder 601 drives the telescopic rod 602 to retract, the movable clamping mechanism 7 drives the covering sleeve 5 to move and open the feeding port 302, and at the same time drives the piston 603 to move to the end of the solution cavity 303 close to the guide cavity 304, wherein the inner diameter of the solution cavity 303 is larger than the inner diameter of the guide cavity 304. Therefore, when the piston 603 moves to fit the guide cavity 304, the piston 603 stops and cannot move further, and the intersection position of the guide cavity 304 and the solution cavity 303 is located on the side of the feeding port 302 away from the mold. , and the feed port 302 is opened at the position of the solution cavity 303, so when the piston 603 moves to the junction of the guide cavity 304 and the solution cavity 303, a liquid storage area is formed, and when the piston 603 moves to the junction of the guide cavity 304 and the solution cavity 303, the feed hopper 4 just moves down and inserts into the feed port 302, so that the metal liquid enters the liquid storage area in the solution cavity 303 through the feed hopper 4, so that the subsequent electric cylinder 601 drives the telescopic rod 602 to extend, pushing the piston 603 to move, so that the metal liquid in the liquid storage area enters the mold for cooling and molding.

[0038] A limiting frame 501 is provided on the outer circumferential wall of the covering sleeve 5; The movable clamping mechanism 7 includes an L-shaped driving rod 701 movably arranged on the limiting frame 501, a retaining ring 702 arranged on the L-shaped driving rod 701, and a reset assembly 10 and a separation wedge block 703 arranged on the L-shaped driving rod 701; The separation wedge block 703 is disposed at the bending portion of the L-shaped driving rod 701 , and the separation wedge block 703 and one end of the molten metal feeding pipe 301 are driven by abutment.

[0039] A positioning groove 604 and a sliding groove 605 are provided on the circumferential side wall of the telescopic rod 602, and the positioning groove 604 and the sliding groove 605 are connected and arranged in an L shape; The positioning groove 604 is matched and plugged with one end of the L-shaped driving rod 701 , and the sliding groove 605 is slidably matched with one end of the L-shaped driving rod 701 .

[0040] Two retaining rings 702 are provided on the L-shaped driving rod 701, and the retaining rings 702 are respectively arranged on both sides of the limiting frame 501, so that when the telescopic rod 602 moves to drive the L-shaped driving rod 701 to move, the retaining ring 702 can drive the covering sleeve 5 to move, wherein the L-shaped driving rod 701 is made to fit the outer wall of the covering sleeve 5 under the action of the reset component 10, and one end of the L-shaped driving rod 701 is inserted into the positioning groove 604, wherein the depth of the positioning groove 604 is greater than the depth of the sliding groove 605, so at this time, when the telescopic rod 602 moves, it can drive the covering sleeve 5 to move through the L-shaped driving rod 701, and when the L-shaped driving rod 701 moves with the telescopic rod 602 When the separating wedge block 703 at the bending part contacts one end of the molten metal feeding tube 301, the L-shaped driving rod 701 is driven by the wedge surface to move away from the covering sleeve 5, so that one end of the L-shaped driving rod 701 inserted in the positioning groove 604 is disengaged and enters the sliding groove 605 as the telescopic rod 602 continues to move. At this time, the continued movement of the telescopic rod 602 will push the piston 603 to push the molten metal into the mold for cooling and forming. The covering sleeve 5 cannot move with the L-shaped driving rod 701 because the locating groove 604 of the telescopic rod 602 is disengaged from the covering sleeve 5, that is, the molten metal is blocked at the feeding port 302 to prevent the molten metal from being splashed due to the push of the piston 603.

[0041] The reset assembly 10 includes a clamping block 1001 disposed on the L-shaped driving rod 701 , and an annular elastic piece 1002 penetrating the clamping block 1001 and sleeved on the outside of the covering sleeve 5 .

[0042] The arrangement of the clamping block 1001 can prevent the annular spring sheet 1002 from moving left and right, and finally break away from the tension on the L-shaped driving rod 701 .

[0043] Specifically, two groups of L-shaped driving rods 701 are provided, which are respectively located at the upper and lower ends of the circumferential side wall of the covering sleeve 5. The clamping block 1001 is C-shaped and welded together with the L-shaped driving rod 701. The annular spring piece 1002 is sleeved on the outside of the two groups of L-shaped driving rods 701, and the position of the clamping block 1001 is located on the circumferential outer wall of the covering sleeve 5, so the annular spring piece 1002 is also sleeved on the outside of the covering sleeve 5, and the annular spring piece 1002 sleeved on the covering sleeve 5 and the two groups of L-shaped driving rods 701 is circular. When the covering sleeve 5 moves to drive the L-shaped driving rod 701 to contact the end of the molten metal feeding pipe 301, the L-shaped driving rod 701 pushes the annular spring piece 1002, so that the annular spring piece 1002 is deformed into an elliptical shape.

[0044] The telescopic rod 602 and the piston 603 are movably connected, and an active cavity 606 and a through hole 607 are formed at one end of the telescopic rod 602 close to the piston 603 .

[0045] The end of the piston 603 close to the telescopic rod 602 is provided with a plug rod 608, and the end of the plug rod 608 away from the piston 603 is provided with an anti-dropping block 609; The anti-dropping block 609 is located inside the movable cavity 606, and the plug-in rod 608 and the through hole 607 are movably plugged.

[0046] The inner diameter of the movable cavity 606 is larger than the inner diameter of the through hole 607, and the inner diameter of the anti-slip block 609 is smaller than the inner diameter of the movable cavity 606, which is larger than the inner diameter of the through hole 607. Therefore, when the telescopic rod 602 moves toward the piston 603 and the anti-slip block 609 moves in the movable cavity 606, the piston 603 will not be pushed to move with the initial movement of the telescopic rod 602 due to the airflow seal.

[0047] Specifically, the piston 603 and the telescopic rod 602 are movably connected, so that when the telescopic rod 602 initially moves, only the L-shaped driving rod 701 pushes the covering sleeve 5 to move, and the feed hopper 4 moves up, and then the covering sleeve 5 blocks the feeding port 302, which does not push the piston 603. Therefore, during the movement of the feed hopper 4 moving up and the covering sleeve 5 moving the feeding port 302, no metal liquid splashing occurs. When the covering sleeve 5 moves to the feeding port 302, the covering sleeve 5 is moved to the feeding port 302. When shielding is achieved, one end of the telescopic rod 602 moves to fit the piston 603, and at this time, the separation wedge block 703 on the L-shaped driving rod 701 conflicts with the end of the molten metal feeding tube 301, so that one end of the L-shaped driving rod 701 is disengaged from the positioning groove 604, and the telescopic rod 602 continues to move, thereby pushing the piston 603 to move, thereby squeezing the molten metal in the liquid storage area into the mold. During the extrusion process, since the feeding port 302 is covered by the sleeve 5, the molten metal will not splash.

[0048] A positioning ring 305 is provided on the molten metal feeding pipe 301 , and an air hole 306 is opened in the guide cavity 304 area on the molten metal feeding pipe 301 .

[0049] A slot 610 is formed on the piston 603; A deformation block 307 is disposed on the inner wall of the solution chamber 303 , and the deformation block 307 is engaged with the slot 610 .

[0050] When the piston 603 is in contact with the junction of the solution chamber 303 and the guide chamber 304, the groove 610 on its surface is engaged with the deformation block 307 on the inner wall of the solution chamber 303. When the telescopic rod 602 moves toward the piston 603, the piston 603 is engaged with the groove 610 and the deformation block 307, thereby avoiding the movement of the piston 603 by the internal airflow when the telescopic rod 602 is pushed. When the telescopic rod 602 is in contact with the piston 603, as the telescopic rod 602 continues to push, the piston 603 releases the engagement between the groove 610 and the deformation block 307 under the thrust of the electric cylinder 601, so that the piston 603 moves with the telescopic rod 602, thereby pushing the internal molten metal into the mold for cooling and molding, thereby completing the casting of the generator end cover.

[0051] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, welding is preferred for all fixed connections. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
