Description

Technical Field

[0001] The invention relates to the field of steam turbine valve outer mold casting, in particular to a wooden outer mold processing center for steam turbine valve casting. Background Art

[0002] The casting of turbine valves mainly adopts the traditional sand box casting method. The upper mold sand mold and the lower mold sand mold are formed by the outer mold. When the upper mold and the lower mold are closed, the upper mold sand mold and the lower mold sand mold are closed to form a cavity. The molten metal enters the cavity from the preset flow channel on the upper mold sand mold. After cooling, the valve casting can be obtained. In order to save costs and facilitate manufacturing, the outer mold currently used is made of wood, and the outer mold of the required shape is obtained by cutting in a machining center for use.

[0003] The Chinese invention patent with the announcement number CN112809437B discloses a three-axis CNC machining center for metal processing, which discloses that: by setting a placement box, a fan and an air outlet pipe, since the bottom of the air outlet pipe is at the same level as the top of the metal part, when the fan is running, the air flow will be discharged through the air outlet pipe, and when the placement box is in a tilted state, the debris on the top of the metal part will slide off, thereby ensuring that the top of the metal part is relatively clean after processing, eliminating the cleaning work of the operator. This solution has the following defects: 1. Clean the debris on the workpiece by tilting the workpiece and coordinating the airflow. To ensure that the debris is sufficiently cleaned, the airflow velocity cannot be too slow, and the airflow will diffuse when discharged from the air outlet pipe, which will inevitably blow most of the small debris out of the placement box, resulting in poor debris collection effect; 2. Only one air outlet pipe is provided for each placement box, and the airflow cannot completely cover the placement box, and the debris in the placement box cannot be cleaned in all directions, resulting in poor cleaning effect.

[0020] In the following, in conjunction with the accompanying drawings, the wooden outer mold processing center for casting turbine valves provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0021] Embodiment 1: like Figures 1 to 10As shown, the embodiment of the present application provides a wooden outer mold processing center for turbine valve casting, including a base 100, a pair of side plates 200, a Y-axis moving beam 300, an X-axis moving frame 400, a Z-axis moving frame 500, a spindle 600, a tool 700 and a debris collection device, the debris collection device includes a collection tank 1, which is arranged in the middle of the base 100, extending along the Y direction, and a split cover plate 2 is provided on the top; a pair of inner grooves 3 are arranged on both sides of the collection tank 1, and a plurality of notches 4 are provided on the top; a pair of chip pushing mechanisms 5 are respectively arranged in each inner groove 3, and can extend through the corresponding notches 4 and push the chips on the top surface of the base 100 into the inner groove 3; the chip pushing mechanism 5 includes a plurality of lifting shells 51, which can be lifted and installed by a lifting unit 6 A side groove 52 is provided in the groove 3 and the corresponding groove opening 4 toward the top of the side wall of the collecting groove 1; a plurality of material pushing shells 53 are floatingly installed in the corresponding side grooves 52 through a plurality of elastic members 7; a plurality of reset devices 8 are used to cooperate with the lifting unit 6 to control each material withdrawal shell, and retract into the side groove 52 before the corresponding lifting shell 51 descends; the material pushing shell 53 includes an outer shell 531, which can be slidably installed in the inner cavity of the lifting shell 51 and the side groove 52, and the inner end is open; an inner shell 532, which can be slidably installed in the outer shell 531, and the inner and outer ends are open; a plurality of damping members 9 are respectively arranged between the outer shell 531 and the inner wall of the lifting shell 51, and between the inner shell 532 and the outer shell 531, and the elastic member 7 is installed between the inner wall of the outer end of the inner shell 532 and the inner cavity of the lifting shell 51.

[0022] Furthermore, the damping member 9 includes a limiting groove 91, which is arranged on the top surface of the inner cavity of the lifting shell 51 or the outer wall of the inner shell 532; a limiting bolt 92 is installed on the top of the inner shell 532 or the outer shell 531 through a screw hole, one end of which extends into the limiting groove 91 and is tightly pressed against the bottom surface of the limiting groove 91 for frictional sliding.

[0023] Furthermore, the elastic member 7 includes a vertical plate 71 , which is fixed to the bottom of the inner cavity of the lifting shell 51 and the upper end extends into the inner cavity of the inner shell 532 ; a thrust spring 72 , which is arranged between the inner wall of the outer end of the outer shell 531 and the vertical plate 71 .

[0024] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the wooden outer mold for casting the turbine valve is placed on the base 100, and the spindle 600 equipped with the tool 700 is driven by the Y-axis moving beam 300, the X-axis moving frame 400, and the Z-axis moving frame 500 to perform three-axis movement, and the surface of the wooden outer mold is processed to remove materials. After the processing is completed, the wooden outer mold is moved out of the base 100, so that a pair of opening and closing cover plates are flipped downward to an inclined state, and then the lifting unit 6 controls each lifting shell 51 to rise from the outside to the inside in sequence. When the outer lifting shell 51 rises to the bottom surface of the corresponding side groove 52 and is flush with the base 100, under the action of the corresponding thrust springs 72, the inner shell 532 and the outer shell 531 of the pushing shell 53 extend out of the side groove 52, and the inner shell 532 extends out of the outer shell 531 at the same time. The bottom end of each limiting bolt 92 rubs against the bottom surface of the corresponding limiting groove 91 to produce damping. Ensure that the extension and retraction process of the inner shell 532 and the outer shell 531 is slow to avoid dust, until the outer end of the inner shell 532 passes through the top surface of the adjacent inner lifting shell 51. As the lifting unit 6 continues to move, the inner shell 532 and the outer shell 531 are controlled to retract into the side groove 52 through the corresponding reset device 8, and each thrust spring 72 is compressed short, and then the adjacent inner lifting shell 51 rises and the outer lifting shell 51 falls. Repeating the above process can push the debris on the top surface of the bottom plate into the collecting groove 1, and then close the split cover plate 2, and the top surface of the split cover plate 2 is flush with the top surface of the base 100, completing the cleaning and collection of the debris on the top surface of the base 100. When it is necessary to clean the debris in the collecting groove 1, flip a pair of opening and closing cover plates downward to open the collecting groove 1, and the worker can suck out the debris in the collecting groove 1 through a vacuum cleaner. The split cover plate 2 is divided into left and right parts, and each part is controlled to rise and fall by a corresponding cylinder.

[0025] Embodiment 2: like Figures 5 to 9 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the lifting unit 6 includes an active sliding block 61, which is driven by a cylinder and slidably installed in the inner groove 3, and a top is provided with a number of notches 62 corresponding to the notches 4; a plurality of transmission grooves 63 are respectively arranged on the side walls of each lifting shell 51, and each has a trapezoidal recessed section 64; a plurality of telescopic transmission blocks 65 are respectively arranged on the side walls of each notch 62, and slidably cooperate with the corresponding transmission grooves 63.

[0026] Preferably, an air sliding section 66 is formed between the front end of the transmission groove 63 and the front end of the trapezoidal recessed section 64, and the lengths of the air sliding sections 66 on adjacent lifting shells 51 are different. Between adjacent lifting shells 51, the length of the air sliding section 66 on the lifting shell 51 away from the collecting groove 1 is greater than the length of the air sliding section 66 on the lifting shell 51 close to the collecting groove 1.

[0027] Furthermore, the telescopic transmission block 65 includes an installation cavity 651, which is arranged in the active sliding block 61 and connected to the missing groove 62 through the sliding hole 652; a telescopic shaft 653, which is slidably installed in the missing groove 62, is made of magnetic conductive material, and the inner end extends into the installation cavity 651, and a floating spring 654 is arranged between the opposite end surface of the installation cavity 651; an electromagnetic coil 655, which is arranged in the installation cavity 651 and surrounds the outer side of the telescopic shaft 653.

[0028] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the cylinder controls the active slider 82 to move toward the end of the transmission groove 63 away from the empty sliding section 66. Correspondingly, each slot 62 and each telescopic shaft 653 (iron) also moves synchronously. The outermost pair of telescopic shafts 653 first enters the corresponding trapezoidal recessed section 64, and slides from the inclined section of the trapezoidal recessed section 64 close to the empty sliding section 66 to the bottom of the trapezoidal recessed section 64. In this process, the outermost lifting shell 51 is pushed up until the pair of telescopic shafts 653 slide to the straight bottom end of the trapezoidal recessed section 64. Then, the pair of telescopic shafts 653 slide from one end of the straight bottom of the trapezoidal recessed section 64 close to the empty sliding section 66 to the other end for a distance, so that the push shell 53 can be fully extended, and then the pair of telescopic sliding transmission blocks cooperate with the corresponding reset device 8 to drive the reset device 8 to control the push shell 53 to retract into the side groove 52. During this process, the height of the lifting shell 51 does not change until the telescopic sliding block moves to the end of the straight bottom of the trapezoidal recessed section 64 away from the empty sliding section 66. At this time, the push shell 53 is completely retracted into the side groove 52, and the telescopic sliding block enters the trapezoidal recessed section 64. The recessed section 64 slides in the inclined section away from the air sliding section 66 toward the section of the transmission groove 63 away from the air sliding section 66. In this process, the corresponding lifting shell 51 is driven to descend. At the same time, the adjacent inner pair of telescopic sliding blocks enter the inclined section of the corresponding trapezoidal recessed section 64 close to the corresponding air sliding section 66, and the adjacent inner lifting shell 51 rises. When the adjacent outer lifting shell 51 descends to the bottom end and contacts the bottom surface of the missing groove 62, the corresponding pair of telescopic shafts 653 also enter the other section of the corresponding transmission groove 63 away from the air sliding section 66. At this time, the outermost lifting shell 51 will not It rises again until all the telescopic shafts 653 enter the other section of the corresponding transmission groove 63 away from the empty sliding section 66, each electromagnetic coil 655 is energized to make each telescopic shaft 653 disengage from the corresponding transmission groove 63, and each floating spring 654 is compressed and shortened. Then the cylinder controls the active slider 82 to move toward the empty sliding section 66 until the end face of the active slider 82 away from the cylinder contacts the end of the inner groove 3 close to the empty sliding section 66, and the cylinder stops moving, each electromagnetic coil 655 is de-energized, and each floating spring 654 pushes the corresponding telescopic shaft 653 into the corresponding empty sliding section 66.

[0029] Embodiment 3: like Fig.10As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the reset device 8 includes a partition 81, which is fixedly arranged between the side wall of the vertical plate 71 away from the collecting tank 1 and the adjacent side wall of the lifting shell 51; a slider 82, which is slidably installed between the bottom surface of the partition 81, the bottom surface of the inner cavity of the lifting shell 51, the side surface of the inner cavity of the lifting shell 51, and the side wall of the vertical plate 71 away from the collecting tank 1; a connecting groove 83, which is arranged on the side wall of the slider 82, corresponding to the trapezoidal recessed section 64; a cable 84, one end of which is fixedly connected to the inner wall of the front end of the outer shell 531, and the other end passes through the vertical plate 71 and is fixedly connected to the end face of the slider 82 away from the trapezoidal recessed section 64 through a fixed pulley set 85; a push piece 10, which is used to lock the slider 82 and push the telescopic transmission block 65 out of the connecting groove 83 when the slider 82 slides to the end of the bottom of the trapezoidal recessed section 64 away from the empty sliding section 66.

[0030] Furthermore, the push member 10 includes a telescopic slide hole 101, which is arranged at the center of the connecting groove 83; a recessed groove 102, which is arranged on the back of the slider 82 and connected to the telescopic slide hole 101; a push slide hole 103, which is arranged on the vertical plate 71 and corresponds to the recessed groove 102; a push block 104, which is installed in the recessed groove 102 and the push slide hole 103 through a reset spring 105, and one end of which can be extended into the telescopic slide hole 101; a push rod 106, which is slidably installed in the telescopic slide hole 101, and the end face of one end is inclined toward the trapezoidal recessed section 64 and can be extended into the recessed groove 102, and a push spring 107 is provided between the other end and the side wall of the lifting shell 51.

[0031] Furthermore, the push member 10 also includes a through groove 108, which is arranged on the side wall of the vertical plate 71 facing away from the slider 82, and the lower end passes through the bottom of the lifting shell 51; a pair of baffles 109 are symmetrically fixed on both sides of the middle part of the peripheral wall of the push block 104; a pair of reset rods 110, the lower ends of which are fixed at the bottom of the inner groove 3, and the upper ends are inclined toward the baffles 109 and can extend into the through groove 108.

[0032] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the corresponding push shell 53 extends out of the side groove 52, each thrust spring 72 is in a relaxed state, and the corresponding slider 82 is located on the side of the bottom straight section of the corresponding trapezoidal recessed section 64 close to the empty sliding section 66. When the telescopic shaft 653 enters the bottom straight section of the trapezoidal recessed section 64 and slides away from the end of the empty sliding section 66, it enters the connecting groove 83, driving the slider 82 to slide together. At this time, the slider 82 pulls the push shell 53 into the corresponding side groove 52 through the cables 84, and the telescopic shaft 653 and the slider 82 continue to slide, cooperating with the inclined outer end surface of the push rod 106, pushing the push rod 106 to retract into the telescopic sliding hole 101, pushing The spring 107 is compressed and shortened, and the slider 82 retracts until each push shell 53 is completely retracted into the corresponding side groove 52. At this time, each push shell 53 has a certain gap with the outer surface of the lifting shell 51, and the slider 82 and the telescopic shaft 653 also move to the end of the straight section at the bottom of the trapezoidal recessed section 64 away from the empty sliding section 66. At this time, the push rod 106 corresponds to the recessed groove 102, and the push spring 107 releases its elastic potential energy to push the push rod 106 into the recessed groove 102, and pushes the other end of the push block 104 into the connecting groove 83, pushing the telescopic shaft 653 out of the connecting groove 83. At this time, the slider 82 is fixed, and then the telescopic shaft 653 can enter the inclined section of the trapezoidal recessed section 64 away from the empty sliding section 66, driving the corresponding The lifting shell 51 descends, and then the top of each reset rod 110 penetrates the through groove 108, and then contacts the side wall of a pair of baffles 109 toward the missing groove 62 and gradually pushes the pair of baffles 109 and the corresponding push rod 106 to move away from the groove 102, until the side groove 52 descends below the top surface of the base 100, and the side wall of the reset rod 110 contacts the side wall of a pair of baffles 109 toward the through groove 108. At this time, the push rod 106 is completely separated from the groove 102, the push spring 107 is compressed, and the reset spring 105 releases its elastic potential energy, pushing the push block 104, so that one end of the push block 104 is separated from the connecting groove 83, and the other end face contacts the side wall of the vertical plate 71. At this time, each thrust The spring 72 releases part of its elastic potential energy, pushing each push shell 53 to slide outward from the side groove 52 until the outer end face abuts against the side wall of the notch 4 or the missing groove 62, and the slider 82 is pulled toward the empty sliding section 66 by the cable 84 to slide until the recessed groove 102 is disengaged from the position corresponding to the push slide hole 103, and when the next lifting shell 51 rises to the bottom of the corresponding side groove 52 and is flush with the top surface of the base 100, the corresponding push shell 53 can be extended out of the lifting shell 51 under the push of the thrust spring 72. In this process, each reset rod 110 disengages from the through groove 108, and the push spring 107 releases its elastic potential energy, pushing one end of the inclined end face of the push rod 106 to extend until each baffle 109 is tightly pressed against the relative surface of the vertical plate 71.

[0033] The elastic force of the return spring 105 is smaller than that of the push spring 107 .
