[0002] In the process of processing metal products, die-casting equipment is often required for die-casting, such as metal copper, zinc, aluminum and aluminum alloy products. Due to its technical characteristics and exhaust requirements, the existing die-casting processing technology will have relatively thick gates on the die-casting blanks (castings), surrounded by a certain number of slag bags, which must be removed before CNC machine processing.

[0003] Among the existing slag bag removal equipment, some are manually clamping and positioning the die castings, and then operating the cutting mechanism to cut, and some are manually clamping the die castings to the manipulator, and then the manipulator cooperates with the cutting mechanism to cut. Although the above cutting methods can be applied to all die castings, the disadvantage is that the degree of processing automation is low;

[0004] There is also a method of placing the casting on a conveying mechanism, adjusting the direction of the casting gate by adjusting the mechanism, and then using a holding mechanism to hold the casting to cut off the casting gate.

[0032] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] An automatic slag removal device for die castings includes a transmission mechanism 4 for transmitting castings 1. For the convenience of description, the transmission mechanism 4 is used as a reference, the direction from the head end to the tail end of the transmission mechanism 4 is set as the X-axis direction, the direction from the rear side to the front side of the transmission mechanism 4 is set as the Y-axis direction, and the direction from the bottom side to the top side of the transmission mechanism 4 is set as the Z-axis direction;

[0034] The casting 1 is sequentially transferred to the first orientation adjustment station, the second orientation adjustment station, and the cutting station through the transfer mechanism 4 .

[0035] A first casting 1 orientation adjustment mechanism for adjusting the casting 1 from the initial adjustment position to the first adjustment position is provided at the first orientation adjustment station. When the casting 1 is in the initial adjustment position, the large end of the casting 1 is in contact with the surface of the conveyor belt of the conveyor mechanism 4, and the small end of the casting 1 is facing upward, so that the casting 1 can be stably moved along with the conveyor mechanism 4. The gate 2 on the side of the casting 1 can be oriented to any position, and the casting 1 can be provided at any position in the Y-axis direction of the conveyor mechanism 4. When the casting 1 is in the first adjustment position, the large end of the casting 1 is in contact with the surface of the conveyor belt of the conveyor mechanism 4, and the small end of the casting 1 is facing upward. The casting 1 is located at the center of the Y-axis direction of the conveyor mechanism 4. The gate 2 on the side of the casting 1 is located in the left area or the right area of ​​the casting 1. The width range of the left area and the right area in the Y-axis direction of the conveyor mechanism 4 is within the narrow mouth width range.

[0036] A second casting orientation adjustment mechanism 39 for adjusting the casting 1 from the first adjustment position to the second adjustment position is provided at the second orientation adjustment station. When the casting 1 is in the second adjustment position, the large end of the casting 1 is in contact with the conveyor belt surface of the conveyor mechanism 4, and the small end of the casting 1 faces upward. The casting 1 is located at the edge of the conveyor mechanism 4 close to the cutting mechanism, and the gate 2 on the side of the casting 1 is located on the front side of the side wall of the casting 1 (the side where the cutting mechanism is installed).

[0037] A cutting auxiliary clamping mechanism 22 and a cutting mechanism are also provided at the cutting station. The cutting auxiliary clamping mechanism 22 and the cutting mechanism are installed at the rear side and the front side of the transmission mechanism 4 respectively.

[0038] A first sensor 5 is arranged between the first orientation adjustment station and the second orientation adjustment station. When the first sensor 5 detects the casting 1 coming out of the first orientation adjustment station, it will drive the second orientation adjustment station to further adjust the casting 1, and move synchronously with the casting 1 and the transmission mechanism 4 during the adjustment process; a second sensor 7 is arranged between the second orientation adjustment station and the cutting station. When the second sensor 7 detects the casting 1 coming out of the second orientation adjustment station, it will drive the cutting auxiliary clamping mechanism 22 to clamp the casting 1, and the clamping component of the cutting auxiliary clamping mechanism 22 clamps the casting 1 and moves synchronously with the transmission mechanism 4, and starts the cutting mechanism for cutting at the same time. The degree of automation is high. Only the casting 1 needs to be placed on the transmission mechanism 4, and the orientation of the casting 1 can be automatically adjusted through the first orientation adjustment station and the second orientation adjustment station; the cutting efficiency is high, the casting 1 completes the gate 2 orientation adjustment and cutting operations during the transmission process, and all processes can be completed without stopping the transmission mechanism 4, thereby improving the cutting efficiency.

[0039] An automatic slag removal device for a die casting 1, comprising a transmission mechanism 4 for transmitting the casting 1;

[0040] Furthermore, the transmission mechanism 4 needs to provide sufficient support force for the transmission of the casting 1 to prevent the casting 1 from shifting during the transmission process. Therefore, a chain conveyor belt can be used. The chain belt of the chain conveyor belt is made of metal plates, has a solid structure, strong bearing capacity, and smooth operation. It is suitable for the transportation of heavy castings 1, mechanical parts and other items. When the casting 1 adjusts its direction and position on the chain belt, since the chain belt is made of metal plates, on the one hand, the direction and position adjustment of the casting 1 is more stable, and on the other hand, it can also reduce the friction between the casting 1 and the chain belt, making it more convenient and smooth for the casting 1 to adjust its direction and position.

[0041] In order to facilitate the removal of waste chips, leakage holes for waste chips to fall can be opened on the chain belt. The casting 1 is generally an irregular structure, so a base can be set at the bottom of the casting 1. On the one hand, the casting 1 can be placed stably on the chain belt, and on the other hand, the casting 1 can be smoothly moved and adjusted on the chain belt with leakage holes through the base.

[0042] A first orientation adjustment station, a second orientation adjustment station and a cutting station are arranged in sequence along the transmission direction of the transmission mechanism 4. The first orientation adjustment station is provided with a first casting 1 orientation adjustment mechanism for adjusting the casting 1 to a first adjustment position. The first casting 1 orientation adjustment mechanism is formed with an eight-shaped passage opening for the casting 1 to pass through, so that the casting 1 moves to the middle of the transmission mechanism 4 and the gate 2 is located on the inlet or outlet side of the casting 1 toward the eight-shaped passage opening.

[0043] Furthermore, a first orientation adjustment station is arranged at the left end of the transmission mechanism 4, and a first casting 1 orientation adjustment mechanism is arranged at the first orientation adjustment station, and the first casting 1 orientation adjustment mechanism is composed of two wedge blocks 3 arranged opposite to each other, and the long right-angled sides of the wedge blocks 3 are fitted and fixed with the limit plates on the rear and front sides of the transmission mechanism 4, and the inclined sides of the wedge blocks 3 face the central axis of the transmission mechanism 4, and an eight-shaped passage opening for the casting 1 to pass through is formed between the two inclined sides, and the left end of the eight-shaped passage opening is a wide opening and the right end is a narrow opening, and the width of the narrow opening is adapted to the diameter of the casting 1, and the height of the wedge block 3 is higher than the position of the gate 2 of the casting 1. Therefore, when the casting 1 in the initial adjustment position passes through the eight-shaped passage opening, the casting 1 will be gathered from any position to the middle position of the Y-axis direction of the transmission mechanism 4, and when the gate 2 of the casting 1 is located on the left side of the side wall of the casting 1 When the casting 1 is on the front or rear side of the side wall of the casting 1, it does not contact with the wedge blocks 3 on the front and rear sides of the transmission mechanism 4. When the gate 2 of the casting 1 is located on the front or rear side of the side wall of the casting 1, it interacts with the wedge blocks 3 on the front and rear sides of the transmission mechanism 4, so that when the casting 1 moves along the transmission mechanism, the gate 2 located on the front or rear side of the side wall of the casting 1 gradually moves toward the left and right sides of the side wall of the casting 1 along the inclined edge of the wedge blocks 3. Finally, the casting 1 after passing through the figure eight through port will move from any position in the Y-axis direction of the transmission mechanism 4 to the middle position in the Y-axis direction of the transmission mechanism 4, and the gate 2 of the casting 1 will also change from the original any position on the side wall of the casting 1 to the left or right side of the side wall of the casting 1, that is, the first adjustment position. The casting 1 automatically completes the first adjustment when it passes between the two wedge blocks 3, and no other operations are required.

[0044] The second direction adjustment station is provided with a sliding seat with adjustable X, Y and Z axis positions, on which a rotating shaft 42 driven to rotate by a motor and a second rotating rod 70 are installed, and a first rotating rod 66 and an elastic holding member 46 are installed at the lower part of the rotating shaft 42. The first rotating rod 66 and the second rotating rod 70 have the same spacing with the rotating shaft 42. During the rotation of the first rotating rod 66, the gate 2 is driven to rotate synchronously until it is clamped between the first rotating rod 66 and the second rotating rod 70. When the gate 2 is clamped between the first rotating rod 66 and the second rotating rod 70, it faces the cutting station side.

[0045] The first rotating rod 66 and the second rotating rod 70 are provided with a first gear 51 and a second gear 58 at the top. When the gate 2 is clamped between the first rotating rod 66 and the second rotating rod 70, the first gear 51 is meshed with the second gear 58. When the second rotating rod 70 is driven to rotate by the motor, the first rotating rod 66 and the second rotating rod 70 rotate in opposite directions to simultaneously apply an outward force to the gate 2 until the first rotating rod 66 and the second rotating rod 70 are in contact with the side wall of the casting 1.

[0046] A first mounting rod 49 is fixed on the rotating shaft 42, and one side of the first mounting rod 49 is connected to the first limiting sleeve 50 through an elastic telescopic rod 53. A first rotating rod 66 is rotatably installed in the first limiting sleeve 50 so that the first gear 51 and the second gear 58 are in elastic contact when they are engaged. The first rotating rod 66 and the second rotating rod 70 apply elastic force to the gate 2.

[0047] Furthermore, the second orientation adjustment station is located behind the first orientation adjustment station, and is used to perform a second adjustment on the casting 1 after the first adjustment, including a multi-axis sliding frame, on which a second casting orientation adjustment mechanism 39 with adjustable X, Y, and Z axis positions is disposed, the second casting orientation adjustment mechanism 39 includes a seventh slide 38, on which an orientation adjustment assembly 52 is disposed, the orientation adjustment assembly 52 includes a mounting plate 43 fixedly connected to the seventh slide 38, on which an eighth drive motor 40 and a ninth drive motor 41 are mounted, and the output shaft of the eighth drive motor 40 passes through the mounting plate 43 and is connected to a rotating shaft The rotating shaft 42 is provided with a fixed sleeve 44, a rotating disk 45 and an elastic holding piece 46 at the end thereof, the rotating disk 45 and the elastic holding piece 46 are rotatably connected with the rotating shaft 42, a first mounting rod 49 is mounted on the fixed sleeve 44, a first limiting sleeve 50 is mounted on the first mounting rod 49, a first rotating rod 66 is rotatably mounted in the first limiting sleeve 50, a first gear 51 is mounted on the top of the first rotating rod 66, the output shaft of the ninth driving motor 41 passes through the mounting plate 43 and is connected with the second rotating rod 70, a wear-resistant sleeve 57 is also sleeved on the upper end of the second rotating rod 70, and the top of the wear-resistant sleeve 57 is fixedly connected with the mounting plate 43 Then, the second gear 58 and the second limiting sleeve 59 are installed on the second rotating rod 70, and the second limiting sleeve 59 is sleeved on the second rotating rod 70. The second limiting sleeve 59 is fixedly connected to the second mounting rod 60, and the second mounting rod 60 is fixedly connected to the rotating disk 45. When operating, the seventh slide 38 is firstly moved synchronously with the casting 1 and located directly above the casting 1 through the multi-axis sliding frame, and then the height of the seventh slide 38 is adjusted through the multi-axis sliding frame so that the elastic holding member 46 is pressed onto the casting 1, so that the casting 1 is stably pressed on the chain plate belt. At this time, the first rotating rod 66 and the second rotating rod 70 are in the same horizontal plane. , the second rotating rod 70 is located at the first preset position, and the first rotating rod 66 is located at the second preset position. When the output shaft of the eighth drive motor 40 rotates to drive the rotating shaft 42 and the first rotating rod 66 to rotate, the elastic holding member 46 rotates relative to the rotating shaft 42, and the elastic holding member 46 and the casting 1 remain relatively stationary. The first rotating rod 66 rotates from the second preset position to the third preset position with the rotating shaft 42. During the rotation, the first rotating rod 66 contacts the gate 2 and drives the casting 1 to rotate, so that the casting 1 changes from the first adjustment position to the second adjustment position, and the gate 2 is clamped between the first rotating rod 66 and the second rotating rod 70.

[0048] Exemplarily, in the present application, the first preset position is when the gate 2 of the casting 1 faces the front side of the transmission mechanism 4, and the position that is closely fitted to the right side edge of the gate 2 is the first preset position; the second preset position is the range from the first preset position to the left boundary of the right area of ​​the casting 1, and the second preset position is adapted to the first preset position, so that when the first rotating rod 66 extends into the second preset position and the second rotating rod 70 extends into the first preset position, there will be no interference with the casting 1 and the gate 2 of the casting 1; the third preset position is when the gate 2 of the casting 1 faces the transmission mechanism 4. When the first rotating rod 66 is directly in front of the mechanism 4, the position that is closely fitted to the left side of the gate 2 is the third preset position, so that the first rotating rod 66 passes through the right area and the left area of ​​the casting 1 in sequence during the rotation of the rotating shaft 42, so that the gate 2 of the casting 1 will contact the first rotating rod 66 regardless of whether it is located in the right area or the left area of ​​the casting 1. After the first rotating rod 66 contacts the gate 2 of the casting 1, it will drive the casting 1 to rotate synchronously, and finally the gate 2 of the casting 1 is clamped between the first rotating rod 66 and the second rotating rod 70. At this time, the gate 2 faces the front side.

[0049] Then, the second rotating rod 70 is driven to rotate by the ninth driving motor 41, and the second rotating rod 70 will drive the first gear 51 to rotate through the second gear 58, and the first gear 51 will drive the first rotating rod 66 to rotate, and the rotation directions of the first rotating rod 66 and the second rotating rod 70 are opposite. For example, in the present application, since the cutting mechanism is arranged on the front side of the transmission mechanism 4, it is necessary to adjust the casting 1 gate 2 to face the front side, and the second rotating rod 70 is located on the right side of the casting 1 gate 2, and the first rotating rod 66 is located on the left side of the casting 1 gate 2. Therefore, the second rotating rod 70 is driven by the ninth motor to rotate counterclockwise and the first rotating rod 66 is driven clockwise, and the second rotating rod 70, The first rotating rod 66 applies a force to the gate 2 toward the front side, and the gate 2 is located in the middle of the casting 1. The top of the casting 1 is limited by the elastic holding member 46, and the bottom of the casting 1 is limited by the chain belt. Therefore, the casting 1 can be moved to the front side until the first rotating rod 66 and the second rotating rod 70 contact the side wall of the casting 1 and the gate 2 of the casting 1 at the same time. At this time, the first rotating rod 66 and the second rotating rod 70 stop rotating, and the seventh drive motor 28 drives the seventh slide 38 to move toward the front side of the transmission mechanism 4. The first rotating rod 66, the second rotating rod 70 and the elastic holding member 46 cooperate with the chain belt to clamp the casting 1 and move it toward the front side of the transmission mechanism 4 until the casting 1 reaches the second adjustment position.

[0050] An elastic holding member 46 capable of rotating and vertically sliding is installed at the lower end of the rotating shaft 42 , and a spring 63 is provided between the rotating shaft 42 and the elastic holding member 46 .

A limiting ring 62 is installed on the top of the piston chamber 65 so that the piston 61 can only move up and down in the piston chamber 65, and the piston cylinder 64 and the piston 61 can rotate relative to each other. When the elastic pressing member 46 is pressed on the upper part of the casting 1, the spring 63 is compressed, and the elastic force of the spring 63 is pressed on the casting 1 through the elastic pressing member 46. On the one hand, it can control the force applied to the casting 1, and on the other hand, it can improve stability.

[0052] Furthermore, a third mounting hole (not shown in the figure) is provided on the rotating shaft 42, and a first mounting hole 55 adapted to the third mounting hole is provided on the fixed sleeve 44.
