Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and specifically to a cutting device and a blanking method for valve body raw materials. Background Art

[0002] In the processing and manufacturing of valves, some welded valve bodies are made by welding metal pipes with other parts. The pipe part is efficiently cut and blanked by a metal circular sawing machine. The structure of the metal circular sawing machine mainly includes a saw blade cutting assembly, a fixture, and a feeding system inside. For thinner raw materials, in order to pursue efficiency, sometimes two metal pipes can be processed at one time. However, such metal circular sawing machines are prone to certain deficiencies when in use: First, the existing fixtures of the circular sawing machine mainly include a horizontally arranged clamping block and a vertically arranged clamping block. When fixing two metal pipes, it is required that the diameters of the two metal pipes are the same. When the diameters of the metal pipes are different, they cannot be fixed, and the applicability is poor. Secondly, during cutting, metal chips remain inside the metal pipe and fall with the metal pipe during blanking, resulting in difficulty in uniformly collecting and processing the metal chips, and they will fall at various positions during the transfer process of the metal pipe, polluting the environment. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a cutting device and a blanking method for valve body raw materials.

[0021] Embodiment 1: Please refer to Figures 1-3 , a cutting device, including a cutting table 1 and a cutting assembly 2 installed in the bed body. A positioning plate 3 is fixed on the cutting table 1. A lateral positioning mechanism 4 is arranged on one side of the positioning plate 3. A vertical positioning mechanism 5 is installed above the cutting table 1. A discharge ramp 6 is fixed at the front end of the cutting table 1, and the discharge ramp 6 is used for conveying workpieces; The lateral positioning mechanism 4 includes a laterally movable lateral clamping block 41, and the vertical positioning mechanism 5 includes two vertically and laterally movable vertical clamping blocks 50. Both the lateral positioning mechanism 4 and the lateral positioning mechanism 4 are used for fixing workpieces; The bottom end of the discharging ramp 6 is provided with a vibration assembly 7 for cleaning debris on and inside the surface of the workpiece. The surface of the discharging ramp 6 is provided with a rotatable bottom plate 8 for discharging the workpiece. Before processing, the vertical positioning mechanism 5 and the lateral positioning mechanism 4 operate. When the lateral positioning mechanism 4 operates, it forces the lateral clamping block 41 to move towards the workpiece. When the vertical positioning mechanism 5 operates, it forces the two vertical clamping blocks 50 to move towards the workpiece to fix the workpiece. After processing, the workpiece slides along the discharging ramp 6 to the bottom end, and the vibration assembly 7 operates to vibrate the workpiece, causing the debris inside and on the surface of the workpiece to fall off. After the debris is cleaned, the bottom plate 8 rotates to discharge the workpiece from the discharging ramp 6.

[0022] Among them, the cylinders and motors in this device are both controlled by the PLC system. The cutting assembly 2 is composed of a saw blade that can move obliquely and is controlled by a servo system. The same as the prior art, the workpiece is two metal pipes. The metal pipes are pushed and fed through the feeding system of the machine bed, so that the ends of the metal pipes move to the cutting station on the cutting table 1. When the cutting assembly 2 operates, the cutting saw blade moves obliquely and then contacts the metal pipe to achieve cutting. During 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 operates, it first drives the two vertical clamping blocks 50 to move vertically and horizontally, and then adjusts the initial positions of the two vertical clamping blocks 50 to adapt to metal pipes of different diameters. Then, it drives the adjusted two vertical clamping blocks 50 to move downward to press the tops of the two metal pipes. At the same time, when the horizontal positioning mechanism operates, it drives the lateral clamping block 41 to move and approach the metal pipe, and jointly clamps the two sides of the two metal pipes with the positioning plate 3 to fix the two metal pipes. Subsequently, the cutting assembly 2 is started to cut the metal pipes. After cutting, the two formed pipe fittings are pushed and slide obliquely along the discharging ramp 6 and are blocked by the vibration assembly 7. At this time, both pipe fittings are located on the bottom plate 8. The vibration assembly 7 is started to vibrate the obliquely placed pipe fittings at the bottom end of the discharging ramp 6, shake off the debris adhered inside and on the surface of the pipe fittings, and then the bottom plate 8 on the discharging ramp 6 swings, and the pipe fittings fall off to achieve discharging. By setting the lateral positioning mechanism 4 and the vertical positioning mechanism 5, the two vertical clamping blocks 50 on the vertical positioning mechanism 5 can adjust the initial positions according to the diameter of the metal pipe, and thus can adapt to the highest point at the top of the metal pipe during clamping, ensuring the stability during clamping, being beneficial to cutting two pipe fittings with different diameters simultaneously, and improving the efficiency. In addition, through the vibration assembly 7 and the movable bottom plate 8, the internal debris of the pipe fittings is shaken off first after being cut and then discharged, avoiding the debris falling on other positions in the workshop when the pipe fittings are transported, being beneficial to the unified collection of debris, and being more environmentally friendly.

[0023] Embodiment 2: Refer to Figure 3, different from the above embodiments, the lateral positioning mechanism 4 further includes a hollow seat 42 fixed on the cutting table 1. One end of the hollow seat 42 faces the positioning plate 3, and a first cylinder 43 is fixed at the other end of the hollow seat 42. The output end of the first cylinder 43 extends into 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. One side of the movable block 44 close to the positioning plate 3 is fixedly connected to the lateral clamping block 41.

[0024] Among them, the lateral clamping block 41 is fixed to the movable block 44 by screws and can be disassembled and replaced according to requirements. During 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 towards the positioning plate 3, contacts and clamps the pipe fitting. By setting the lateral positioning mechanism 4, the movement of the lateral clamping block 41 is controlled by the telescopic movement of the first cylinder 43, which facilitates the clamping of the pipe fitting and makes the pipe fitting more stable during the cutting process.

[0025] Embodiment Three. Refer to Figure 3 and Figure 4 , different from the above embodiments, the vertical positioning mechanism 5 includes a column 51 fixed on the hollow seat 42. A cross beam 52 is fixed at the top of the column 51. A second cylinder 53 is fixed on the cross beam 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 are movably inserted into the cross beam 52. A transverse guide rail 56 is fixed at the bottom of the mounting plate 54. Two sets of symmetrically distributed driving components 57 are installed on the transverse guide rail 56. The two sets of driving components 57 are respectively used to drive the two vertical clamping blocks 50 to move vertically and horizontally. The driving component 57 includes a transverse motor 571 fixed at the end of the transverse guide rail 56. The output end of the transverse motor 571 is fixed with a transverse screw rod 572. The end of the transverse screw rod 572 is movably installed on the transverse guide rail 56 through an upper bearing seat 573. A nut seat 574 is threadedly connected to the transverse screw rod 572. The nut seat 574 is slidably connected to the transverse guide rail 56. The bottom of the nut seat 574 is fixed with a frame 575. A vertical motor 576 is fixed inside the frame 575. The output shaft of the vertical motor 576 is fixed with a vertical screw rod 577. A screw hole is provided at the top end of the vertical clamping block 50. The vertical screw rod 577 is threadedly connected to the screw hole. Two symmetrically distributed guide rails 501 are fixed at the top end of the vertical clamping block 50. The guide rails 501 are vertically slidably connected to the side wall of the frame 575.

[0026] Among them, the two vertical clamping blocks 50 are just located directly above the cutting station. When initially processing, the diameter information of two metal pipe fittings is input into the equipment, and the transverse motor 571 and the vertical motor 576 are started accordingly. When the transverse motor 571 operates, it drives the transverse screw rod 572 to rotate. When the transverse screw rod 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 rod 577, and the vertical clamping block 50 to move, so as to adjust the horizontal position of the vertical clamping block 50. When the vertical motor 576 operates, it drives the vertical screw rod 577 to rotate, and then drives the vertical clamping block 50 and the guide rail 501 to move vertically, so as to adjust the height of the vertical clamping block 50. Finally, the two vertical clamping blocks 50 can be adjusted to appropriate initial positions respectively, so that they can adapt to the tops of two juxtaposed metal pipes. After that, the second cylinder 53 is started. After the second cylinder 53 operates and extends, it drives the mounting plate 54 and the guide rod 55 to move vertically downward. When the mounting plate 54 moves downward, it drives the two vertical clamping blocks 50 mounted at the bottom to move downward, and finally contacts the two metal pipes respectively, pressing and fixing the two metal pipes. By setting the vertical positioning mechanism 5 and using the two adjustable vertical clamping blocks 50, the position of the vertical clamping block 50 can be pre-adjusted before clamping the metal pipe, so that it can adapt to metal pipes of different diameters, and then move downward and press the metal pipe, so that the two metal pipes can be fixed simultaneously.

[0027] Example 4, refer to Figure 3 , 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.

[0028] Among them, both the first avoidance groove and the second avoidance groove are matched with the position of the saw blade on the cutting assembly 2, so as to avoid the moving saw blade and prevent interference with the cutting work of the saw blade.

[0029] Example 5, refer to Figure 5 , different from the above embodiment, the discharge ramp 6 includes an inclined plate 61 and baffles 62 fixed on both side edges of the inclined plate 61. An adjusting plate 63 is provided between the two baffles 62. An adjusting screw rod 64 is fixed on the adjusting plate 63. The adjusting screw rod 64 penetrates through the baffle 62 and is fixed to the baffle 62 through a nut 65.

[0030] Among them, two nuts 65 are provided. Both nuts 65 are installed on the adjusting screw rod 64 and are located on both sides of the baffle 62. Rotating the two nuts 65 can control the position of the adjusting plate 63. In actual use, the gap between the adjusting plate 63 and one of the baffles 62 just adapts to the two metal pipes to be processed, so that the two metal pipes slide down along the inclined plate 61 after being cut, ensuring that the ends of the metal pipes are downward when sliding.

[0031] Example 6, refer to Figure 6, different from the above embodiments, 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 installed 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 uniformly distributed blocking 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 on the side wall of the baffle 62. A first incomplete gear 707 and a short-diameter gear 708 are fixed on the output shaft of the starting motor 706. The first incomplete gear 707 is matched with the driven gear 705. An opening is provided near the bottom end of the surface of the inclined plate 61. The bottom plate 8 is located within the opening and a secondary shaft 715 is fixed at its edge. The secondary shaft 715 is movably installed at the bottom of the inclined plate 61 through a 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 at the end of the secondary shaft 715. A transmission shaft 712 is also rotatably connected on the baffle 62. A long-diameter gear 713 and a second incomplete gear 714 are fixed on the transmission shaft 712. The long-diameter gear 713 is meshed with the short-diameter gear 708. The second incomplete gear 714 is matched with the transmission gear 711.

[0032] Among them, the bottom plate 8 matches the opening size. In the initial state, the bottom plate 8 is flush with the inclined plate 61 in terms of angle. The stop lever 704 on the horizontal shaft 701 extends to the inner side of the bottom end of the discharge ramp 6, which has an obstructive effect on the sliding metal pipe. During use, the motor 706 is started to operate. The motor 706 drives the first incomplete gear 707 and the short-diameter gear 708 to rotate. During the rotation of the first incomplete gear 707, it contacts the driven gear 705, causing the driven gear 705 to rotate by a certain angle. When the driven gear 705 rotates, it drives the horizontal shaft 701 to rotate. When the horizontal shaft 701 rotates, it drives the stop lever 704 to swing. And when the horizontal shaft 701 rotates, it also forces the first torsion spring 703 to deform. After the first incomplete gear 707 disengages from the driven gear 705, the elastic force of the first torsion spring 703 drives the horizontal shaft 701 to rotate back to its original position, thereby causing the baffle 62 to return to its original position. Therefore, when the first incomplete gear 707 continuously drives the driven gear 705 to rotate intermittently, the stop lever 704 makes high-frequency reciprocating swings, having a vibration effect. When the bottom end of the metal pipe collides with the stop lever 704, the impact force and the vibration effect of the stop lever 704 cause the metal debris in the metal pipe to fall off. Since the metal pipe is in an inclined state at this time, the metal debris finally falls from the bottom end of the metal pipe, thus achieving the cleaning effect. In addition, when the short-diameter gear 708 rotates, it also drives the long-diameter gear 713 to rotate slowly. When the long-diameter gear 713 rotates, it drives the transmission shaft 712 and the second incomplete gear 714 to rotate. Similarly, when the second incomplete gear 714 rotates, it drives the transmission gear 711 to rotate intermittently. When the transmission gear 711 rotates intermittently, it drives the auxiliary shaft 715 to rotate intermittently and return to its original position under the action of the second torsion spring 710, thereby driving the bottom plate 8 to swing intermittently, and the swing frequency is lower than that of the stop lever 704. After the bottom plate 8 swings, the metal pipe inclines along the bottom plate 8 and falls from the gap, realizing the material discharging; By setting the vibration assembly 7, the starting motor 706 can be used to drive the stop lever 704 to swing at a high frequency, thereby playing a function of cleaning debris from the metal pipe during material discharging, which is beneficial 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 after the cleaning of the metal pipe is completed, the metal pipe is discharged, realizing the separate material discharging work of the metal pipe, so as to uniformly collect the metal pipes.

[0033] Embodiment Seven, refer to Figure 7 and Figure 8, different from the above embodiments, a detection component 9 is further provided on the surface of the vertical clamping block 50. 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. A servo motor 92 is fixed at the top of the vertical guide rail 91. A driving screw 93 is fixed on the output shaft of the servo motor 92. 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. The slider 94 is sleeved on the driving screw 93 and is threadedly connected to the driving screw 93. An assembly plate 95 extending downward is fixed on the slider 94. A third cylinder 96 is fixed on the assembly plate 95. An angle steel 97 is fixed on the output end of the third cylinder 96. A pressure sensor 98 is fixed on the angle steel 97. A vertically arranged probe 99 is fixed on the pressure sensor 98.

[0034] Among them, when the metal pipe is first processed, the vertical positioning mechanism 5 operates to drive the two vertical clamping blocks 50 to clamp the end of the metal pipe. Subsequently, the servo motor 92 is started. When the servo motor 92 operates, it drives the driving screw 93 to rotate, thereby driving the slider 94 to move downward along the vertical guide rail 91, driving the assembly plate 95 and the third cylinder 96 to move downward, so that the third cylinder 96 points to the inner cavity of the metal pipe. 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 metal pipe. Subsequently, the servo motor 92 is started again to control the probe 99 to move upward. When the probe 99 contacts the inner top wall of the metal pipe, the pressure sensor 98 measures a change in value, and the servo motor 92 stops operating. This method can measure the thickness of the metal pipe. Before the initial cutting operation, the thicknesses of two metal pipes are measured, and then the servo system on the cutting component 2 controls the moving speed of the saw blade when cutting the two metal pipes respectively. A faster saw blade traveling speed is adopted for the thinner metal pipe, which is beneficial to improving the cutting efficiency.

The scope of the present invention is defined by the appended claims and their equivalents.
