Description

Technical Field

[0001] The utility model belongs to the field of pipe casting, and in particular relates to a two-in-one pipe casting device that can be used for pipe drawing and spraying. Background Art

[0002] The pipe casting mechanism sometimes needs to spray the inner wall of the pipe mold before casting, and the pipe cast in the pipe mold needs to be removed after the casting is completed. In the existing technology, the spraying of the inner wall of the pipe mold and the extraction of the cast pipe are both performed by workers holding related equipment, which is time-consuming, labor-intensive and inconvenient to operate. Utility Model Content

[0003] The purpose of the utility model is to solve the problems in the prior art, thereby providing a two-in-one pipe pulling and spraying equipment. Through this equipment, not only can the pipe casting mechanism be polished and sprayed, but the pipe fittings cast in the pipe casting mechanism can also be pulled out, which saves time and effort and is easy to operate.

[0004] The purpose of the utility model is achieved as follows: a two-in-one pipe pulling and spraying casting equipment comprises a pipe pulling mechanism, a feeding mechanism is provided on the right side of the pipe pulling mechanism, a frame is provided on the left side of the pipe pulling mechanism, an I-beam is provided on the frame, the left and right ends of the I-beam are connected to the frame for up and down sliding connection, a lifting and switching mechanism is connected between the I-beam and the frame, a movable frame A is connected to the upper flange of the I-beam for left and right sliding connection, a spraying mechanism is connected to the movable frame A, a movable frame B is connected to the lower flange of the I-beam for left and right sliding connection, the movable frame B is connected to the pipe pulling mechanism, a pipe feeding mechanism is provided below the pipe pulling mechanism on the frame, and the pipe feeding mechanism is connected to the frame for left and right sliding connection.

[0005] Furthermore, the lifting and switching mechanism includes a vertical adjustment screw connected to the I-beam through a thread, and both ends of the vertical adjustment screw are rotatably connected to the frame. By rotating the vertical adjustment screw, the I-beam is driven to move upward or downward to switch the spraying mechanism / tube extraction mechanism on the work station.

[0006] Furthermore, the tube pulling mechanism includes a mounting seat fixedly connected to the movable frame B, a positioning rod is connected to the center of the mounting seat for sliding left and right, and a positioning plate is fixedly connected to the right end of the positioning rod. No less than three support rods are arranged around the positioning rod, and the support rods are evenly distributed around the positioning rod. The left end of the support rod is hinged on the mounting seat, and a torsion spring is connected at the hinge point between the support rod and the mounting seat. The left end of the positioning rod is connected to the piston rod of the hydraulic rod, and the pressure cylinder of the hydraulic rod is fixedly connected to the mounting seat. The hydraulic rod drives the positioning rod and the positioning plate to move left and right. The distance between the movable end of the support rod and the positioning rod can be adjusted by the support of the positioning plate and the coordinated reset of the torsion spring, and then the distance between the support rod and the inner wall of the pipe fitting can be adjusted to achieve the fixing and unlocking of the tube pulling mechanism and the pipe fitting as needed, thereby facilitating the tube pulling operation.

[0007] Furthermore, the positioning plate is a truncated cone structure with an outer end diameter larger than an inner end diameter, and the maximum diameter of the positioning plate is larger than the aperture of the inscribed circle between the struts, and the minimum diameter of the positioning plate is smaller than the aperture of the inscribed circle between the struts. When the hydraulic rod pushes the positioning plate to move to the rightmost end, the left end of the positioning plate is located in the central area of ​​the strut. When the positioning plate moves to the left, there is no need to position the relative position of the positioning plate and the strut to prevent the movable end of the suspended strut from hindering the movement of the positioning plate. During the movement of the positioning plate, its obliquely arranged side surface can drive the movable end of the strut to gradually rotate in the direction away from the positioning rod.

[0008] Furthermore, a friction sleeve is fixedly connected to the outer surface of the support rod near the right end, which can increase the friction between the tube pulling mechanism and the inner wall of the pipe fitting, preventing the tube pulling mechanism from moving relative to the pipe fitting due to insufficient friction during the process of moving the pipe fitting together.

[0009] Furthermore, the feeding mechanism includes a feeding trolley, which moves left and right along the trolley track A. A material box is installed on the feeding trolley. The top of the material box is rotatably connected to the feeding trolley on the side close to the casting pipe mechanism. The material box is connected to a rotary drive mechanism, and then the rotary drive mechanism drives the material box to flip over so that the molten iron in the material box is fed into the casting pipe mechanism through the feeding port.

[0010] Furthermore, the cast pipe feeding mechanism includes a feeding trolley, which moves left and right along the trolley track B. The feeding trolley is provided with a plurality of lifting mechanisms along its length direction, and the lifting mechanisms can provide support for the pipe fittings.

[0011] Furthermore, the lifting mechanism includes a vertical lifting frame and a horizontal support shaft connected to the top of the vertical lifting frame. A proximity switch is provided on the left side of the lifting mechanism on the feeding trolley. When the pipe pulling mechanism drives the pipe to pass over a proximity switch, the horizontal support shaft corresponding to its right side moves upward under the push of the vertical lifting frame to provide support for the pipe passing over it.

[0012] Furthermore, two frustum-shaped support rollers are symmetrically arranged on the horizontal support axis, and the large diameter ends of the two support rollers are located at the end positions of the horizontal support axis. The support rollers at both ends of the horizontal support axis can limit the pipe fittings on the horizontal support axis to prevent the pipe fittings from rolling along the axial direction of the horizontal support axis.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model is equipped with a two-in-one mechanism of spraying and polishing at the discharge port of the pipe casting mechanism. The spraying mechanism and the pipe pulling mechanism are connected with a vertical switching mechanism. The mechanism staying at the working position can be switched through the vertical switching mechanism. Through this mechanism, not only the pipe casting mechanism can be sprayed, but also the pipe fittings cast in the pipe casting mechanism can be pulled out, which saves time and effort and is easy to operate.

[0015] 2. The utility model is provided with a casting pipe feeding mechanism below the pipe pulling mechanism, through which the pipe fittings taken out from the casting pipe mechanism can be automatically fed into the corresponding material frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment of the present invention, Figure 1 As shown, a two-in-one pipe pulling and spraying casting equipment includes a pipe casting mechanism 1, a feeding mechanism 2 is provided on the right side of the pipe casting mechanism 1, a frame 2 is provided on the left side of the pipe casting mechanism 1, an I-beam crossbeam 17 is provided on the frame 2, the left and right ends of the I-beam crossbeam 17 are connected to the frame 2 for up and down sliding, a lifting and switching mechanism is connected between the I-beam crossbeam 17 and the frame 2, a movable frame A3 is connected to the upper flange of the I-beam 17 for left and right sliding, the movable frame A3 is connected to the spraying mechanism 5, the lower flange of the I-beam 17 is connected to the movable frame B4 for left and right sliding, the movable frame B4 is connected to the pipe pulling mechanism 6, a pipe feeding mechanism is provided below the pipe pulling mechanism 6 on the frame 2, and the pipe feeding mechanism is connected to the frame 2 for left and right sliding.

[0028] In one embodiment of the present invention, Figure 1 As shown, the lifting and switching mechanism includes a vertical adjustment screw 16 connected to the I-beam 17 by a thread, and both ends of the vertical adjustment screw 16 are rotatably connected to the frame 2. By rotating the vertical adjustment screw 16, the I-beam 17 is driven to move upward or downward to switch the spraying mechanism 5 / tube pulling mechanism 6 on the work station.

[0029] In one embodiment of the present invention, the movable frame A3 and the movable frame B4 are respectively connected to linear motors, which drive the movable frame A3, the movable frame B4, the spraying mechanism 5 and the tube pulling mechanism 6 to move left and right.

[0030] In one embodiment of the present invention, Figure 3As shown, the tube pulling mechanism 6 includes a mounting seat 18 fixedly connected to the mobile frame B4, a positioning rod 19 is connected to the center of the mounting seat 18 for sliding left and right, and a positioning plate 20 is fixedly connected to the right end of the positioning rod 19. No less than three support rods 21 are arranged around the positioning rod 19, and the support rods 21 are evenly distributed around the positioning rod 19. The left end of the support rod 21 is hinged to the mounting seat 18, and a torsion spring 22 is connected at the hinge point between the support rod 21 and the mounting seat 18. The left end of the positioning rod 19 is connected to the piston rod of the hydraulic rod 23. The pressure cylinder of the hydraulic rod 23 is fixedly connected to the mounting seat 18. The hydraulic rod 23 drives the positioning rod 19 and the positioning plate 20 to move to the left along the axial direction of the positioning rod 19 through the piston rod. Under the support of the positioning plate 20 , the movable end of the support rod 21 rotates in the direction away from the positioning rod 19, so that the movable end of the support rod 21 abuts against the inner surface of the pipe fitting, thereby realizing the fixation of the pipe fitting inside the casting mechanism by the pipe pulling mechanism 6, so that the pipe fitting can be pulled out of the casting mechanism through the movable frame B4, and the pulled-out pipe fitting is placed on the casting pipe feeding mechanism. Then the hydraulic cylinder 23 drives the positioning rod 19 and the positioning plate 20 to move to the right along the axial direction of the positioning rod 19 through the piston rod. After losing the supporting effect of the positioning plate 20, under the action of the torsion spring 22, the movable end of the support rod 21 rotates in the direction of the positioning rod 19, so that the movable end of the support rod 21 is away from the inner surface of the pipe fitting, releasing the fixation of the pipe pulling mechanism 6 and the pipe fitting, and finally the pipe pulling mechanism 6 is moved out of the pipe fitting through the movable frame B4, making it convenient for the casting pipe feeding mechanism to send the pipe fitting into the material frame.

[0031] In one embodiment of the present invention, Figure 3 As shown, the positioning disk 20 is a truncated cone structure with an outer end diameter larger than an inner end diameter, and the maximum diameter of the positioning disk 20 is larger than the aperture of the inscribed circle between the struts 21, and the minimum diameter of the positioning disk 21 is smaller than the aperture of the inscribed circle between the struts 21. When the hydraulic rod 23 pushes the positioning disk 20 to move to the rightmost end, the left end of the positioning disk 20 is located in the central area of ​​the strut 21. When the positioning disk 20 moves to the left, there is no need to position the relative position of the positioning disk 20 and the strut 21 to prevent the movable end of the suspended strut 21 from hindering the movement of the positioning disk 20. During the movement of the positioning disk 20, its obliquely arranged side surface can drive the movable end of the strut 21 to gradually rotate in the direction away from the positioning rod 19.

[0032] In one embodiment of the present invention, Figure 3 As shown, a friction sleeve 24 is fixedly connected to the outer surface of the support rod 21 near the right end. The friction sleeve 24 can increase the friction between the tube pulling mechanism 6 and the inner wall of the pipe fitting, thereby preventing the tube pulling mechanism 6 from moving relative to the pipe fitting due to insufficient friction when moving the pipe fitting together.

[0033] In one embodiment of the present invention, Figure 1 As shown, the feeding mechanism includes a feeding trolley 7, which moves left and right along the trolley track A8. A material box 9 is installed on the feeding trolley 7. The top of the material box 9 is close to the side of the casting pipe mechanism 1 and is rotatably connected to the feeding trolley 7. A rotary drive mechanism is connected to the material box, which drives the feeding trolley 7 to rotate and delivers the molten iron in the material box 9 to the casting pipe mechanism 1; a feeding trolley is provided on the right side of the feeding trolley 7, which moves back and forth along the vertical direction perpendicular to the trolley track A8. The feeding trolley can pour molten iron into the material boxes 9 of different feeding trolleys 7, so that the feeding trolleys 7 can dump molten iron into their respective casting pipe mechanisms 1 in a quantitative manner.

[0034] In one embodiment of the present invention, Figure 1 As shown, the cast pipe feeding mechanism includes a feeding trolley 10, which moves left and right along the trolley track B11. The feeding trolley 10 is provided with a plurality of lifting mechanisms along its length direction, which can provide support for the pipes pulled out by the pipe pulling mechanism.

[0035] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the lifting mechanism includes a vertical lifting frame 13 and a horizontal support shaft 14 connected to the top of the vertical lifting frame 13. A proximity switch 12 is provided on the left side of the lifting mechanism on the feeding trolley 10. When the pipe pulling mechanism 6 drives the pipe to pass over a proximity switch 12, the corresponding horizontal support shaft 14 on its right side moves upward under the push of the vertical lifting frame 13 to provide support for the pipe passing over it.

[0036] In one embodiment of the present invention, Figure 2 As shown, two conical support rollers 15 are symmetrically arranged on the horizontal support shaft 14, and the large diameter ends of the two support rollers 15 are located at the end positions of the horizontal support shaft. The support rollers 15 at both ends of the horizontal support shaft 14 can limit the pipe fittings on the horizontal support shaft 14 to prevent the pipe fittings from rolling along the axial direction of the horizontal support shaft 14.

[0037] The workflow of this utility model is as follows:

[0038] 1. Press the reset button and all actions return to the origin;

[0039] 2. Press the spray start button, the spray mechanism 5 starts to move to the right along the axis of the tube mold. When it moves to the spraying position inside the tube mold, the spray valve opens, and returns after moving to the front limit position. After it returns to the spraying position inside the tube mold, the spray valve closes until the spray mechanism returns to the origin, and then automatically switches to the tube pulling position (secondary cooling is required during spraying, and the screen must show the spraying and watering time).

[0040] 3. Press the bag turning start button, the loading trolley 7 moves toward the pipe casting mechanism 1 to the specified position, and at the same time the centrifuge drives the pipe mold to increase to the specified speed, the loading trolley 7 turns the bag to dump the molten iron in the loading trolley 7 into the pipe mold of the pipe casting mechanism, and then the loading trolley 7 returns to its original position. (If the pipe mold speed does not turn or does not turn to the set low speed, the bag turning start cannot be pressed to prevent the molten iron from pouring into the pipe mold when the pipe mold is not turning. It is forced to move to the front limit, and the speed must reach the set high speed standard to turn the bag. If either of these two points is not met, the bag cannot be turned to prevent the molten iron from not pouring into the pipe mold and injuring people. The bag turning will not move if the spray rod does not reach the rear limit start).

[0041] 4. After the pipe mold stops rotating, remove the blocking disk and press the pipe pulling start button. If the pipe mold is not stopped, the pipe pulling start button will not work. The pipe pulling mechanism 6 moves toward the pipe casting mechanism 1. When the pipe pulling mechanism 6 moves to the specified position, the support rod 26 opens and drives the cast pipe back. When the support rod 21 passes over a certain lifting mechanism, the corresponding lifting mechanism rises, and then the support rod 21 closes. Then all the lifting mechanisms drive the cast pipe to descend, the pipe pulling mechanism returns to its original position, and switches to the spraying station. The left side of the lifting mechanism is respectively provided with A proximity switch 12 is provided to detect the position of the cast pipe; the feeding trolley 10 drives the lifting mechanism and the cast pipe above it to move to the left to the specified position and then stops, the unloading valve on the feeding trolley 10 is opened to lower the cast pipe into the material frame, and the feeding trolley 10 drives the lifting mechanism to return to the origin. The feeding trolley 10 cannot return to the origin without the lifting mechanism descending, to prevent the lifting mechanism from colliding with the pipe pulling mechanism 6; as long as the pipe pulling mechanism 6 moves forward, all lifting mechanisms must descend otherwise they are easily damaged, and the support rod 21 must also be closed.

[0042] The above is merely a preferred embodiment of the present invention and only specifically describes the technical principles of the present invention. These descriptions are intended only to explain the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be imagined by those skilled in the art without inventive effort, shall be included within the scope of protection of the present invention.
