Description

[0002] In the processing and manufacturing of valves, some welded valve bodies are made by welding metal pipes to other parts. The pipe part is efficiently cut and cut by a metal circular saw machine. The structure of the metal circular saw machine mainly includes an internal saw blade cutting component, a clamp and a feeding system. For thinner raw materials, in order to pursue efficiency, sometimes two metal pipes can be processed at one time. However, this type of metal circular saw machine is prone to certain shortcomings when used: first, the clamp of the existing circular saw machine mainly includes a horizontally set clamp block and a vertically set clamp block. When fixing the two metal pipes, the two metal pipes must have the same diameter. When the metal pipes have different diameters, they cannot be fixed, and the applicability is poor. Secondly, when cutting, metal debris remains inside the metal pipe, which falls with the metal pipe during cutting, making it difficult to collect and process the metal debris in a unified manner. The metal debris will fall to various locations during the transportation process of the metal pipe, polluting the environment. Summary of the Invention

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a cutting device and a cutting method for valve body raw materials.

[0032] Example 1: Please refer to Figure 1-Figure 3 A cutting device comprises a cutting table 1 and a cutting assembly 2 installed in a bed, a positioning plate 3 is fixed on the cutting table 1, a lateral positioning mechanism 4 is provided on one side of the positioning plate 3, a vertical positioning mechanism 5 is installed above the cutting table 1, and a discharge ramp 6 is fixed at the front end of the cutting table 1, and the discharge ramp 6 is used to transport the workpiece;

[0033] The lateral positioning mechanism 4 includes a lateral clamping block 41 capable of laterally moving, and the vertical positioning mechanism 5 includes two vertical clamping blocks 50 capable of laterally and vertically moving. Both the lateral positioning mechanism 4 and the lateral positioning mechanism 4 are used to fix the workpiece;

[0034] A vibration assembly 7 is provided at the bottom end of the discharge ramp 6, and the vibration assembly 7 is used to clean the debris on the surface and inside of the workpiece. A rotatable bottom plate 8 is provided on the surface of the discharge ramp 6, and the bottom plate 8 is used to discharge the workpiece;

[0035] Before processing, the vertical positioning mechanism 5 and the lateral positioning mechanism 4 are in operation. When the lateral positioning mechanism 4 is in operation, the lateral clamping block 41 is forced to move toward the workpiece. When the vertical positioning mechanism 5 is in operation, the two vertical clamping blocks 50 are forced to move toward the workpiece to fix the workpiece. After processing, the workpiece slides to the bottom end along the discharge ramp 6, and the vibration component 7 is in operation to vibrate the workpiece to cause debris inside and on the surface of the workpiece to fall off. When the debris is cleaned, the bottom plate 8 rotates to discharge the workpiece from the discharge ramp 6.

[0036] Among them, the cylinder and motor in this device are controlled by the PLC system. The cutting component 2 is composed of a saw blade that can move obliquely and is controlled by a servo system. Similar to the existing technology, the workpiece is two metal pipes. The metal pipes are pushed and loaded through the loading system of the bed, so that the ends of the metal pipes are moved to the cutting station on the cutting table 1. When the cutting component 2 is running, the cutting saw blade moves obliquely and contacts the metal pipe to achieve cutting;

[0037] When in use, the two metal pipes are pushed to one side of the positioning plate 3, and then the vertical positioning mechanism 5 and the horizontal positioning mechanism are started. When the vertical positioning mechanism 5 is in operation, the two vertical clamping blocks 50 are first driven to move vertically and horizontally, and then the initial positions of the two vertical clamping blocks 50 are adjusted to adapt to metal pipes of different diameters. Then, the two adjusted vertical clamping blocks 50 are driven downward to press the tops of the two metal pipes. At the same time, when the horizontal positioning mechanism is in operation, the lateral clamping blocks 41 are driven to move and approach the metal pipes, and the positioning plate 3 is tightened. Clamp the two sides of the two metal pipes together to fix the two metal pipes, then start the cutting assembly 2 to cut the metal pipes. After cutting, the two formed pipe fittings are pushed and slide obliquely along the discharge ramp 6, and are blocked by the vibration assembly 7. At this time, the two pipe fittings are both on the bottom plate 8. Start the vibration assembly 7 to make the oblique pipe fittings vibrate at the bottom end of the discharge ramp 6, shaking off the debris inside and on the surface of the pipe fittings, and then the bottom plate 8 on the discharge ramp 6 swings, and the pipe fittings fall down, realizing unloading;

[0038] By setting up a lateral positioning mechanism 4 and a vertical positioning mechanism 5, the two vertical clamping blocks 50 on the vertical positioning mechanism 5 can adjust the initial position according to the diameter of the metal pipe, and then can adapt to the highest point of the top of the metal pipe when clamping, thereby ensuring stability during clamping, which is conducive to cutting two pipes of different diameters at the same time and improving efficiency. In addition, through the vibration component 7 and the movable bottom plate 8, the internal debris of the pipe is shaken off after being cut before unloading, avoiding the debris falling to other places in the workshop when the pipe is transported, which is conducive to the unified collection of debris and is more environmentally friendly.

[0039] Example 2: See Figure 3 , different from the above embodiment, the lateral positioning mechanism 4 also includes a hollow seat 42 fixed on the cutting table 1, one end of the hollow seat 42 faces the positioning plate 3, and the other end of the hollow seat 42 is fixed with a first cylinder 43, the output end of the first cylinder 43 extends to the interior of the hollow seat 42 and is fixed with a movable block 44, the movable block 44 is slidably connected to the inner wall of the hollow seat 42, and the movable block 44 is fixedly connected to the lateral clamping block 41 close to the positioning plate 3.

[0040] The lateral clamping block 41 is fixed to the movable block 44 by screws and can be disassembled and replaced as needed. When in use, the first cylinder 43 is started. When the first cylinder 43 extends, it pushes the movable block 44 to slide. When the movable block 44 slides, it drives the lateral clamping block 41 to move. The lateral clamping block 41 moves toward the positioning plate 3 to contact and clamp the pipe fitting.

[0041] By providing the lateral positioning mechanism 4 and utilizing the extension and contraction of the first cylinder 43 to control the movement of the lateral clamping block 41 , it is convenient to clamp the pipe and make the pipe more stable during the cutting process.

[0042] Example 3, see Figure 3 and Figure 4 , different from the above embodiment, the vertical positioning mechanism 5 includes a column 51 fixed on the hollow seat 42, a crossbeam 52 is fixed on the top of the column 51, a second cylinder 53 is fixed on the crossbeam 52, the output end of the second cylinder 53 is vertically downward and is fixed with a mounting plate 54, a plurality of guide rods 55 are fixed on the top of the mounting plate 54, the guide rods 55 are vertically arranged and movably connected to the crossbeam 52, a transverse guide rail 56 is fixed at the bottom of the mounting plate 54, two sets of symmetrically distributed drive assemblies 57 are installed on the transverse guide rail 56, and the two sets of drive assemblies 57 are used to drive the two vertical clamping blocks 50 to move vertically and transversely respectively, and the drive assembly 57 includes a transverse electric motor fixed at the end of the transverse guide rail 56. Machine 571, the output end of the horizontal motor 571 is fixed with a horizontal screw 572, the end of the horizontal screw 572 is movably mounted on the horizontal guide rail 56 through an upper bearing seat 573, the horizontal screw 572 is threadedly connected with a nut seat 574, the nut seat 574 is slidably connected to the horizontal guide rail 56, the bottom of the nut seat 574 is fixed with a frame 575, a vertical motor 576 is fixed in the frame 575, the output shaft of the vertical motor 576 is fixed with a vertical screw 577, the top of the vertical clamp 50 is provided with a screw hole, the vertical screw 577 is threadedly connected to the screw hole, the top of the vertical clamp 50 is fixed with two symmetrically distributed guide rails 501, the guide rails 501 are vertically slidably connected to the side walls of the frame 575.

[0043] Among them, the two vertical clamping blocks 50 are just located above the cutting station. During the initial processing, the diameter information of the two metal pipes is input to the equipment, and the horizontal motor 571 and the vertical motor 576 are started. When the horizontal motor 571 is running, it drives the horizontal screw 572 to rotate. When the horizontal screw 572 rotates, it drives the nut seat 574 to slide horizontally along the guide rail, thereby driving the bottom frame 575, the vertical motor 576, the vertical screw 577 and the vertical clamping block 50 to move, thereby adjusting the horizontal position of the vertical clamping block 50. When the vertical motor 576 is running, When the second cylinder 53 is started, the second cylinder 53 extends and drives the mounting plate 54 and the guide rod 55 to move vertically downward. When the mounting plate 54 moves downward, the two vertical clamping blocks 50 installed at the bottom are driven downward, and finally contact the two metal pipes respectively, pressing the two metal pipes tightly and fixing them.

[0044] By setting up a vertical positioning mechanism 5 and using two adjustable vertical clamps 50, the position of the vertical clamp 50 can be pre-adjusted before clamping the metal pipe so that it can adapt to metal pipes of different diameters, and then moved down to press the metal pipe, so that two metal pipes can be fixed at the same time.

[0045] Example 4, see Figure 3 , which is different from the above embodiment, a first avoidance groove is provided on the lateral clamping block 41 , and a second avoidance groove is provided on the vertical clamping block 50 .

[0046] The first avoidance groove and the second avoidance groove are both matched with the position of the saw blade on the cutting assembly 2, so as to avoid the moving saw blade and avoid interfering with the cutting work of the saw blade.

[0047] Example 5, see Figure 5 , different from the above embodiment, the discharge ramp 6 includes an inclined plate 61 and baffles 62 fixed on the edges of both sides of the inclined plate 61, an adjustment plate 63 is provided between the two baffles 62, and an adjusting screw 64 is fixed on the adjusting plate 63, and the adjusting screw 64 passes through the baffle 62 and is fixed to the baffle 62 by a nut 65.

[0048] Among them, there are two nuts 65, both of which are installed on the adjusting screw 64 and located on both sides of the baffle 62. The position of the adjusting plate 63 can be controlled by rotating the two nuts 65. In actual use, the gap between the adjusting plate 63 and one of the baffles 62 is just suitable for the two metal pipes to be processed, so that the two metal pipes can slide along the inclined plate 61 after being cut, ensuring that the ends of the metal pipes face downward when sliding.

[0049] Example 6, see Figure 6 , different from the above embodiment, the vibration assembly 7 includes a horizontal shaft 701 located at the bottom end of the discharge ramp 6, the horizontal shaft 701 is movably mounted on the edge of the baffle 62 through two main bearing seats 702, a first torsion spring 703 is fixed at the connection between the horizontal shaft 701 and the main bearing seat 702, a plurality of evenly distributed baffle rods 704 are fixed on the horizontal shaft 701, a driven gear 705 is also fixed at the end of the horizontal shaft 701, a starting motor 706 is fixed to the side wall of the baffle 62, and a first incomplete gear 707 and a short-diameter gear 708 are fixed to the output shaft of the starting motor 706, the first incomplete gear 707 and the driven gear 705 are fixed to the output shaft of the starting motor 706. To match, an opening is provided on the surface of the inclined plate 61 near the bottom end, the bottom plate 8 is located in the opening and a secondary shaft 715 is fixed to the edge, the secondary shaft 715 is movably mounted on the bottom of the inclined plate 61 through the secondary bearing seat 709, a second torsion spring 710 is fixed at the connection between the secondary shaft 715 and the secondary bearing seat 709, a transmission gear 711 is fixed to the end of the secondary shaft 715, and a transmission shaft 712 is also rotatably connected to the baffle 62, a long-diameter gear 713 and a second incomplete gear 714 are fixed to the transmission shaft 712, the long-diameter gear 713 is meshed with the short-diameter gear 708, and the second incomplete gear 714 is matched with the transmission gear 711.

[0050] When the first incomplete gear 707 is disengaged from the driven gear 705, the elastic force of the first torsion spring 703 drives the horizontal shaft 701 to rotate and reset, thereby resetting the baffle 62. When the gear 711 rotates, the secondary shaft 715 rotates intermittently and resets under the action of the second torsion spring 710, thereby driving the bottom plate 8 to swing intermittently, and the swinging frequency is lower than the baffle 704. After the bottom plate 8 swings, the metal pipe tilts along the bottom plate 8 and falls from the gap to achieve material unloading.

[0051] By setting up the vibration component 7, the starting motor 706 can be used to drive the blocking rod 704 to swing at a high frequency, thereby cleaning the debris of the unloaded metal pipes, which is conducive to the unified treatment of debris and is more environmentally friendly. At the same time, the starting motor 706 can also drive the bottom plate 8 to swing at a low frequency, and the metal pipes will be discharged after the cleaning is completed, thereby realizing the separate unloading of the metal pipes so that the metal pipes can be collected in a unified manner.

[0052] Example 7, see Figure 7 and Figure 8, different from the above embodiment, the surface of the vertical clamping block 50 is further provided with a detection component 9, and the detection component 9 is used to detect the wall thickness of the workpiece. The detection component 9 includes a vertical guide rail 91 fixed on the vertical clamping block 50, and a servo motor 92 is fixed to the top of the vertical guide rail 91. The output shaft of the servo motor 92 is fixed with a driving screw 93, and the driving screw 93 is located in the vertical guide rail 91 and is rotatably connected to the vertical guide rail 91. A slider 94 is slidably connected to the vertical guide rail 91, and the slider 94 is sleeved on the driving screw 93 and threadedly connected to the driving screw 93. A downwardly extending assembly plate 95 is fixed on the slider 94, and a third cylinder 96 is fixed on the assembly plate 95. An angle steel 97 is fixed to the output end of the third cylinder 96, and a pressure sensor 98 is fixed on the angle steel 97. A vertically arranged probe 99 is fixed on the pressure sensor 98.

[0053] Among them, when the metal tube is processed for the first time, the vertical positioning mechanism 5 operates, driving the two vertical clamping blocks 50 to clamp the end of the metal tube, and then the servo motor 92 is started. When the servo motor 92 operates, it drives the drive screw 93 to rotate, and then drives the slider 94 to move down along the vertical guide rail 91, driving the assembly plate 95 and the third cylinder 96 to move down, so that the third cylinder 96 points to the inner cavity of the metal tube. At this time, the third cylinder 96 is started, and the third cylinder 96 extends to drive the angle steel 97, the pressure sensor 98 and the probe 99 to extend into the interior of the metal tube. Then, the servo motor 92 is started again to control the probe 99 to move upward. When the probe 99 contacts the top wall of the metal tube, the pressure sensor 98 detects the value change and the servo motor 92 stops operating. This method can measure the thickness of the metal tube. Before the initial cutting work, the thickness of the two metal tubes is measured, and then the servo system on the cutting assembly 2 controls the movement speed of the saw blade when cutting the two metal tubes respectively. A faster saw blade travel speed is used for thinner metal tubes, which is conducive to improving cutting efficiency.

[0054] Embodiment 8 is a method for cutting valve body raw materials. This method for cutting valve body raw materials uses a cutting device in the above embodiment.
