DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 3 , a metal chain component processing and forming equipment in this embodiment includes a box body 1, the front and rear sides of the box body 1 are both open, a hydraulic push rod 2 is fixed on the inner top wall of the box body 1, and an infusion tube is fixedly connected to the right side of the hydraulic push rod 2, and an end of the infusion tube away from the hydraulic push rod 2 is fixedly connected to a hydraulic pump, and a switching mechanism 3 capable of switching between punching and blanking is provided at the bottom of the hydraulic push rod 2, a base 7 is fixed on the inner bottom wall of the box body 1, and the base 7 is used to provide a stable support force for the collecting component 4, and a collecting component 4 capable of separately collecting the punching waste and the blanking material is provided on the left side of the switching mechanism 3, and one end of the collecting component 4 extends into the base 7, and a plurality of stabilizing components 5 for improving the stability of the collecting component 4 are provided on the inner top wall of the box body 1, and the bottoms of the plurality of stabilizing components 5 are fixed to the collecting component 4, and a cleaning component 6 for blowing and flushing the waste is provided on the inner bottom wall of the box body 1 and located on the left side of the base 7, and the top of the cleaning component 6 is fixed to the collecting component 4.

[0023] In addition, the switching mechanism 3 includes a protective shell 301 fixed to the bottom of the hydraulic push rod 2, the protective shell 301 is used to protect the servo motor 302 and other parts, and can provide stable support for the servo motor 302 and other parts. The inner top wall of the protective shell 301 is fixed with the servo motor 302, and the output end of the servo motor 302 is fixed with an active rod 303. The bottom of the active rod 303 is rotatably connected to the inner bottom wall of the protective shell 301 through a bearing. The outer surface of the active rod 303 is fixed with a driving gear 304, and the left and right sides of the driving gear 304 are meshed with driven gears 305. The driving gear 304 drives the two driven gears 305 to rotate at the same time, thereby prompting the two punching knives 307 to rotate at the same time. The bottom of each driven gear 305 is fixed with a connecting ring 306, and the bottom of each connecting ring 306 is connected by a shaft. The bearing is rotatably connected to the inner bottom wall of the protective shell 301, and the bearing can improve the stability of the connecting ring 306, thereby indirectly providing good stability for the driven gear 305. A punching knife 308 is fixed to the bottom of the protective shell 301, and the inner side of each driven gear 305 is movably connected with a punching knife 307 that sequentially penetrates the bottom wall of the protective shell 301 and the punching knife 308. The outer surfaces of the two punching knives 307 are threadedly connected to the punching knife 308. Since the punching knife 308 is fixed to the inner bottom wall of the protective shell 301, when the punching knife 307 rotates, it can achieve the effect of rotation and rising under the action of the threaded connection. The inner bottom wall of the protective shell 301 and located directly above the left punching knife 307 are rotatably connected with a rotating rod 309 through a bearing. The rotating rod 309 extends into the left punching knife 307 and meshes with the left punching knife 307.

[0024] It should be further explained that two transmission blocks are fixed on the inner side of each driven gear 305, and two transmission grooves are provided on the outer surface of the left punching knife 307. The vertical length of the transmission groove is greater than the vertical length of the transmission block, so that the transmission block and the transmission groove cooperate to ensure that the rotational force is carried out smoothly. At the same time, when the punching knife 307 moves upward, the rotational force of the driven gear 305 can still be continuously transmitted to the punching knife 307. The two transmission blocks extend into the two transmission grooves respectively and are movably connected with the transmission grooves. A meshing groove is provided on the top of the left punching knife 307, and a plurality of internal teeth are fixed in each meshing groove. A plurality of external teeth are fixed on the outer surface of the rotating rod 309, and the plurality of external teeth are meshed with the plurality of internal teeth. Since the length of the rotating rod 309 is constant and the height of the punching knife 307 on the left can be adjusted up and down, the meshing connection between the internal teeth and the external teeth is always maintained through the setting of the meshing groove. The meshing effect of the plurality of external teeth and the plurality of internal teeth is similar to the cooperation effect of the transmission block and the transmission groove, and both can ensure the stable transmission of torque during the up and down movement of the punching knife 307.

[0025] In this embodiment, by controlling the punching knife 307 to move up and down, the space in the box body 1 can be further saved. At the same time, the power of the rotation of the punching knife 307 will be transmitted to the collecting component 4 to achieve the classification of the punching waste and the blanking parts.

[0026] Please refer again Figure 1 and Figures 4 to 7 In order to facilitate subsequent sorting, the collecting assembly 4 in this embodiment includes a connecting plate 401 fixed to the left side of the protective shell 301. The connecting plate 401 can not only provide support for the movable fixed pulley 402, but also transmit the power for the hydraulic push rod 2 to move up and down. A movable fixed pulley 402 is fixed at the bottom of the connecting plate 401 and away from the protective shell 301. A stable fixed pulley 403 is fixed to the inner left wall of the box body 1 and directly below the movable fixed pulley 402. The movable fixed pulley 402, the stable fixed pulley 403 and the winding fixed pulley 404 are all fixed by a stable seat. The stable seat and the pulley are in a rotational connection relationship. A connecting portion 406 is provided on the base 7. A collecting portion 407 is provided on the right side of the connecting portion 406 and located in the base 7. A winding fixed pulley 404 is fixed on the left side, and a torsion spring is provided inside the winding fixed pulley 404. When the pull rope 405 loses external force, the pull rope 405 will be wound around the winding fixed pulley 404 under the action of the torsion spring. The pull rope 405 wound on the winding fixed pulley 404 plays a buffering role. The outer surface of the winding fixed pulley 404 is wound with the pull rope 405, and the pull rope 405 passes around the stable fixed pulley 403 and the movable fixed pulley 402 in turn. The stable fixed pulley 403 and the movable fixed pulley 402 can change the direction of the pull rope 405, which is convenient for the pull rope 405 to pull the connecting part 406 and the collecting part 407. A winding drum is fixed on the outer surface of the rotating rod 309, and the side of the pull rope 405 away from the winding fixed pulley 404 passes through the protective shell 301 and is fixed to the outer surface of the winding drum.

The height of the movable hole is greater than the sum of the heights of the connecting seat 4065 and the punching die 4068. Three hydraulic chambers are opened in sequence from left to right in the connecting seat 4065. A hydraulic piston 4066 is movably connected to each hydraulic chamber. When hydraulic oil is injected into the hydraulic chamber, the hydraulic piston 4066 can be pushed to move the hydraulic piston 4066 upward, thereby driving the punching die 4068 to move upward. A connecting rod 4067 that passes through the top wall of the hydraulic chamber is fixed on the top of each hydraulic piston 4066. A punching die 4068 is fixed on the top of the three connecting rods 4067 and above the connecting seat 4065. A connecting pipe 4069 is fixedly connected to the output end of the liquid pump 4063.

[0028] In addition, the input end of the liquid pump 4063 is fixedly connected to the liquid tank 4062, and the connecting pipe 4069 extends from the side away from the liquid tank 4062 to the leftmost hydraulic cavity. A plurality of oil passages are provided in the connecting seat 4065, and the oil passages can allow the hydraulic oil to pass smoothly to ensure that the pressures in the three hydraulic cavities remain consistent. Every two hydraulic cavities are connected through the oil passages.

[0029] In addition, two punching channels are provided on the connecting seat 4065, and a feeding hole is provided at the bottom of the forming mold 4064.

[0030] It should be further explained that an opening is provided on the top of the base 7, and the feed hole corresponds to and is connected to the upper and lower positions of the opening. A collecting hole is provided on the base 7 and passes through the base 7. The U-shaped frame 4061 extends into the collecting hole. The collecting portion 407 includes a collecting trolley 4071 fixed to the right side of the U-shaped frame 4061. Four rollers are fixed to the bottom of the collecting trolley 4071, and the rollers can help the collecting trolley 4071 to move more easily. A switch door is hinged on the front of the collecting trolley 4071 through a hinge. The bottom of the collecting trolley 4071 is movably connected to the bottom wall of the collecting hole. A limiting groove is provided on the base 7 and is located below the collecting hole and is connected to the collecting hole. Two mounting holes are provided in the bottom wall of the box body 1 and are located below the limiting groove. The groove is used to provide space and support for the limit electric push rod 4073. A limit rod 4072 extending into the limit groove is fixed at the bottom of the collection cart 4071. The limit electric push rods 4073 are fixed in the two installation grooves. A shift rod that penetrates the bottom wall of the limit groove and extends into the limit groove is fixed on the top of each limit electric push rod 4073. When the shift rod is raised, the limit rod 4072 can be blocked. When the shift rod moves downward, the limit rod 4072 loses its blocking effect and can move freely. Connecting balls are fixed on the right side of the collection cart 4071 and the right wall inside the box body 1. The outer surfaces of the two connecting balls are sleeved with stabilizing springs. The stabilizing springs are mainly used to provide pulling force to assist the collection cart 4071 to return to its position.

[0031] In addition, each stabilizing component 5 includes a stabilizing rod 501 fixed to the inner top wall of the box body 1, and multiple moving rods 503 are fixed to the top of the connecting plate 401. The stabilizing rod 501 can limit the freedom of the moving rod 503 to ensure that the moving rod 503 can only move up and down. At the same time, the stabilizing rod 501 can also support the side of the connecting spring 502 to ensure that the connecting spring 502 can smoothly release its elastic potential energy. The connecting spring 502 is in a compressed state. The multiple moving rods 503 extend into the multiple stabilizing rods 501 respectively and are movably connected to the stabilizing rods 501. A connecting spring 502 is abutted between the top of each moving rod 503 and the inner top wall of the stabilizing rod 501.

[0032] Furthermore, the cleaning component 6 includes a collecting seat 601 fixed to the inner bottom wall of the box body 1, the collecting seat 601 is located behind the pull rope 405, an air inlet is opened on the right side wall of the collecting seat 601, a first-level one-way valve 604 is fixed on the inner side of the collecting seat 601 and below the air inlet, and a second-level one-way valve 605 is fixed on the inner side of the air inlet. When the compression rod 603 moves downward, the first-level one-way valve 604 opens and the second-level one-way valve 605 closes, and the gas is compressed below the first-level one-way valve 604. When the compression rod 603 moves upward, the first-level one-way valve 604 closes and the second-level one-way valve 605 opens, and the outside air smoothly enters below the pneumatic piston 602. A compression rod 603 extending into the collecting seat 601 is fixed to the bottom of the connecting plate 401, and a pneumatic piston 602 is fixed to the bottom of the compression rod 603. A pressure relief valve 606 is fixedly connected to the right side of the collecting seat 601. The pressure relief valve 6 06 is fixedly connected to the right side with a stabilizing tube 607. When the air pressure in the collecting seat 601 reaches the threshold set by the pressure relief valve 606, the pressure relief valve 606 opens, and the pressurized gas will enter the collecting vehicle 4071, causing the punching waste to be concentrated in the front area. The inner side of the stabilizing tube 607 is movably connected with a moving tube 608. The side of the moving tube 608 away from the stabilizing tube 607 passes through the inner rear wall of the collecting vehicle 4071. A partition is fixed to the inner bottom wall of the collecting vehicle 4071 and located on the right side of the moving tube 608. A forward-inclined oblique block is fixed to the inner bottom wall of the collecting vehicle 4071. The oblique block is located on the left side of the partition and below the moving tube 608. The oblique block is arranged to be low in front and high in the back, so that when the moving tube 608 jets forward, the debris can be blown and accumulated at the low point at the front end of the inner cavity of the collecting vehicle 4071, thereby facilitating the opening and closing door on the front side of the collecting vehicle 4071 to clean up the debris.

[0033] In this embodiment, one end of the movable tube 608 away from the stabilizing tube 607 is parallel to the inclined surface of the inclined block, and a plurality of sealing rings are fixed to the outer surface of the movable tube 608. The plurality of sealing rings are all located inside the stabilizing tube 607, and the sealing rings are used to improve air tightness.

[0034] It can be understood that when the servo motor 302 is running, the two limit electric push rods 4073 retract at the same time, and when the servo motor 302 stops, the two limit electric push rods 4073 are pushed up at the same time. The equipment has high stamping efficiency and subsequent sorting is also convenient.

[0035] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0036] The working principle of the above embodiment is: (1) When in use, first convey the steel sheet to the device, start the hydraulic push rod 2, and then drive the switching mechanism 3 to move downward. At this time, the steel sheet is punched by two punching knives 307, and the punched waste will directly fall into the left chamber of the collection vehicle 4071. When the hydraulic push rod 2 returns to its original position, the servo motor 302 is started. The power of the servo motor 302 is output to the two driven gears 305 through the driving gear 304, thereby driving the punching knife 307 inside the driven gear 305 to rotate. Due to the threaded connection between the punching knife 307 and the blanking knife 308, the punching knife 307 will rotate and move upward at this time, and the servo motor 302 will rotate and move upward. When the motor 302 is started, the two limit electric push rods 4073 will shrink inward at the same time. As the punching knife 307 rotates with the rotating rod 309, the winding drum will continuously reel in the pull rope 405, and the pulling force will be transmitted to the collection vehicle 4071, leading the collection vehicle 4071 to move to the left. When the limit rod 4072 moves to the leftmost side, the servo motor 302 stops. At this time, the two limit electric push rods 4073 are pushed upward at the same time to limit the limit rod 4072. At this time, the right chamber of the collection vehicle 4071 is opened opposite to the top of the base 7, so as to facilitate the collection of the subsequent stamped outer chain plates.

[0037] (2) When the pull rope 405 is continuously stretched but the pull rope 405 wound on the winding fixed pulley 404 is not completely pulled out, the position of the collecting portion 407 remains relatively unchanged, and the liquid pump 4063 continuously pumps the hydraulic oil in the connecting seat 4065 into the liquid tank 4062. At this time, the three hydraulic pistons 4066 will move the three connecting rods 4067 downward until the punching die 4068 fits with the top of the connecting seat 4065. When the pull rope 405 wound on the winding fixed pulley 404 is completely pulled out, Continue to reel in the pull rope 405, and the collecting part 407 and the connecting part 406 will move to the left together until the collecting vehicle 4071 moves to the leftmost side, and turn off the servo motor 302. At this time, the rightmost side of the connecting seat 4065 also moves into the moving hole, so that the connecting seat 4065 is no longer located under the steel sheet, thereby not hindering the collection of the steel sheet after stamping. After the adjustment is completed, start the hydraulic push rod 2, and under the action of the punching knife 308, the formed parts will fall smoothly into the collecting vehicle 4071.

[0038] (3) After the punching is completed, the servo motor 302 is started in the reverse direction. At the same time, the two limit electric push rods 4073 will retract inward at the same time. As the pull rope 405 is continuously released, the collection vehicle 4071 will move to the right under the action of the stabilizing spring. When the collection vehicle 4071 moves to the far right, the connecting part 406 also returns to its original position. At this time, the liquid pump 4063 is started. The liquid pump 4063 draws the hydraulic oil in the liquid tank 4062 into the connecting seat 4065. The three hydraulic pistons 4066 drive the connecting rod 4067 to move upward, causing the punching die 4068 to press against the bottom of the steel plate. Then, the steel plate is driven to move through the subsequent device, and punching can be performed again.

[0039] (4) Each time the hydraulic push rod 2 is pressed down, the connecting plate 401 is pressed down. The downward pressure causes the compression rod 603 to drive the pneumatic piston 602 to move downward. The gas enters the lower part of the primary check valve 604 through the primary check valve 604. When the compression rod 603 moves upward, it drives the pneumatic piston 602 to move upward. The external gas enters the collecting seat 601 through the secondary check valve 605. Through the reciprocating action, a large amount of gas is pushed to the lower part of the primary check valve 604. When the pressure reaches the threshold of the pressure relief valve 606, the pressure relief valve 606 will open to flush the punching waste, causing the waste to be gathered together. Finally, by opening the switch door on the front of the collection vehicle 4071, the accumulated waste can be cleaned up. Cleaning is convenient and fast.
