[0020] See also Figure 1-7 The present invention provides a technical solution: a high-speed punching machine processing and conveying device based on a hydraulic servo system and a working method thereof, comprising a feeding chamber 1 and a punching machine body 7, The feed chamber 1 is arranged adjacent to the punch body 7; A storage cavity 4 is provided in the feeding chamber 1, and a plurality of sheet material bodies 6 to be loaded are arranged vertically in the storage cavity 4. A feeding port 2 is provided on the upper side of the feeding chamber 1, and the storage cavity 4 is provided in the feeding port 2; A movable feeding tray 3 is arranged in the feeding chamber 1, an opening is arranged at one end of the storage cavity 4, and a material taking mechanism is arranged at the open end. The material taking mechanism includes a plurality of electric suction cups 101, and the electric suction cups 101 are used to absorb and take out a single sheet body 6 from the storage cavity 4 and place it on the feeding tray 3; A discharge port 5 is provided at one end of the feeding chamber 1 close to the punch body 7, and a pair of transmission rollers 501 are provided inside the discharge port 5. The feeding tray 3 feeds the sheet body 6 into the pair of transmission rollers 501, and the transmission rollers 501 are used to transmit the sheet body 6 to the punch body 7 for stamping and forming.

[0021] First, a batch of stacked sheet bodies 6 are manually placed directly in the storage chamber 4 of the feed port 2. An open end is set at one end of the storage chamber 4 to facilitate the screening and loading of the sheet bodies 6. Then, the electric suction cup 101 is driven by the material taking mechanism to adsorb the vertical sheet body 6 and take it out of the storage chamber 4 to complete the screening work. During the screening process, no friction will be generated between the sheet bodies 6, thereby avoiding surface scratches between the sheets caused by friction, and further ensuring the surface quality. The screened sheet material body 6 is placed on the feed tray 3, and the feed tray 3 moves with the sheet material body 6 and feeds it into a pair of transmission rollers 501; a pair of transmission rollers 501 clamps the sheet material body 6 and transmits it into the punch press body 7, thereby completing the automatic screening and loading work, and no manual loading is required. This is suitable for batch stamping production work, which greatly improves work efficiency.

[0022] The material storage chamber 4 includes a supporting vertical plate 401, and the two ends of the supporting vertical plate 401 are fixedly connected with a concave plate 402. The middle side of the concave plate 402 is hingedly connected to a limit block 403, and a torsion spring is arranged at the hinge of the limit block 403.

A storage groove is provided on the middle side of the support vertical plate 401 , and the storage groove is matched with the push plate 405 .

[0023] Preferably, limit blocks 403 are provided on both sides of the opening end, and the limit blocks 403 can rotate outward and reset under the action of the torsion spring, so as to limit the several sheet material bodies 6 in the storage chamber 4. When it is necessary to take out the material, the electric suction cup 101 absorbs the sheet material body 6 and takes it out, and the sheet material body 6 pushes the limit blocks 403 to open outward until the sheet material body 6 is completely out of the storage chamber 4, and then under the reset action of the torsion spring, the limit blocks 403 reset and restrict the subsequent sheet material bodies 6 again; In order to further improve the stability of the electric suction cup 101 when taking materials, and prevent the sheet material body 6 in the storage chamber 4 from tipping over after being reduced, a push plate 405 is provided, and a spring member can be preferably provided to push the push plate 405, so that the push plate 405 always pushes the sheet material body 6 toward the opening end, and under the restriction of the limit block 403, a plurality of sheet material bodies 6 are kept in a vertical state, and the push plate 405 also further supports the sheet material body 6, thereby improving the stability of the electric suction cup 101 in sucking; When the staff needs to put the sheet body 6, the push plate 405 is retracted into the receiving groove to avoid interference.

[0024] A support plate 102 is provided on one side of the electric suction cup 101, a fixed rod 103 is fixedly connected to the middle side of the support plate 102, a pair of extension columns 8 are fixedly connected to the lower ends of both ends of the feeding chamber 1, a swing rod 104 is hingedly connected to the inner side of the extension column 8, and both ends of the fixed rod 103 penetrate the upper end of the swing rod 104 and are rotatably connected thereto; An annular groove is provided on the inner side of the swing rod 104, in which a swivel is rotatably connected. A connecting rod 105 is fixedly connected to one end of the swivel, and a rotating rod 106 is rotatably connected to one end of the connecting rod 105. A pair of turntables 107 are fixedly connected at both ends of the rotating rod 106. The turntables 107 are rotatably connected to the inner side of the feeding chamber 1, and a connecting column 108 is fixedly connected between the turntables 107 on both sides. The turntable 107 on either side is driven to rotate by the motor assembly.

[0025] Preferably, when screening and feeding work is required, the motor assembly is used to drive the turntable 107 on either side to rotate, and the connecting column 108 is used to drive the turntables 107 on both sides to rotate synchronously. The rotating rod 106 is eccentrically arranged on the turntable 107. When the turntable 107 rotates, the connecting rod 105 is driven to swing. The connecting rod 105 is rotationally connected to the swing rod 104, and the lower end of the swing rod 104 is rotationally connected to the extension column 8. Then, the swing rod 104 is pushed by the connecting rod 105 to swing back and forth, thereby driving the upper fixed rod 103, the support plate 102 and the electric suction cup 101 to move. When the swing rod 104 and the support plate 102 are perpendicular to the horizontal line (such as Figure 2 As shown in the figure), the electric suction cup 101 can contact and adsorb the sheet material body 6, and then the swing rod 104 swings toward the feeding tray 3, which can drive the sheet material body 6 to move to the feeding tray 3, completing the screening and feeding, and in this process, the fixed rod 103 rotates adaptively to adjust the angle of the electric suction cup 101, thereby adsorbing the sheet material body 6 in the vertical state and putting down the sheet material body 6 in the horizontal state.

[0026] Both ends of the fixed rod 103 are fixedly connected with a connecting seat 109, one end of the connecting seat 109 is fixedly connected with a guide column 110, one end of the guide column 110 is slidably matched with a guide sleeve 111, one end of the guide sleeve 111 is fixedly connected with a limiting disk 112, the limiting disk 112 is rotatably connected to the side wall of the feeding chamber 1, the guide column 110 passes through the inner side of the limiting disk 112 and slidably matches with it, when the guide column 110 is parallel to the horizontal line, the electric suction cup 101 contacts and adsorbs the sheet body 6.

[0027] Preferably, when it is necessary to control the fixed rod 103 to rotate adaptively, a limit plate 112 is provided, the guide column 110 and the guide sleeve 111 are slidably matched, and the guide column 110 passes through the inner side of the limit plate 112 and is slidably matched therewith, so that the limit plate 112 limits the angle of the fixed rod 103 and the electric suction cup 101. When the swing rod 104 and the support plate 102 are both perpendicular to the horizontal line, the axis of the fixed rod 103 and the axis of the limit plate 112 are on the same horizontal line, and the guide column 110 and the guide sleeve 111 are parallel to the ground (such as Figure 2As shown), the electric suction cup 101 contacts and adsorbs the sheet body 6, and then, with the swing of the swing arm 104, the connecting seat 109 is displaced, the guide column 110 and the guide sleeve 111 slide against each other for guidance, and the limit plate 112 rotates accordingly to adapt, so that the angle of the electric suction cup 101 is gradually adjusted until the guide column 110 is perpendicular to the ground, so that the electric suction cup 101 and the sheet body 6 are in a horizontal state and on the upper side of the feeding tray 3, and the loading work can be completed. That is to say, through the setting of the limit plate 112, the angle of the electric suction cup 101 is limited, so that it can be adaptively rotated under the swinging action of the swing arm 104, so as to facilitate timely adjustment to the appropriate angle to absorb and put down the sheet body 6, without the need to use additional drive components or control programs for control, and has strong practicality.

[0028] Guide bars 301 are fixedly connected to both ends of the feed tray 3, and guide grooves 302 are opened on both sides of the inner wall of the feeding chamber 1. The guide bars 301 slide in cooperation with the guide grooves 302. The length of the feed tray 3 is smaller than the length of the sheet body 6. One end of the sheet body 6 close to the discharge port 5 extends out of the outside of the feed tray 3. The upper end of the feed tray 3 is fixedly connected to a limiting frame 303.

[0029] Preferably, when the sheet body 6 falls on the feed tray 3, one end of the sheet body 6 close to the discharge port 5 extends out of the outside of the feed tray 3, so as to facilitate the transmission by the transmission roller 501, and a limiting frame 303 is provided to limit the other end of the sheet body 6, so as to facilitate the feed tray 3 to drive the sheet body 6 to move, and the guide bar 301 is guided along the guide groove 302 to further improve the stability of the feed tray 3.

[0030] An adaptation groove is provided at the middle side of both ends of the guide bar 301, and a driving lower rod 304 is hinged in the swinging groove. A driving upper rod 305 is provided at the upper end of the driving lower rod 304, and a plurality of guiding telescopic rods 306 are provided between the driving upper rod 305 and the driving lower rod 304. A fan gear 307 is fixedly connected to the upper end of the driving upper rod 305, and a gear part 308 is meshingly connected to the upper side of the fan gear 307. The gear part 308 is fixedly connected to the limit plate 112, and a swinging adaptation groove 113 is provided on the inner wall of the feeding chamber 1. The fan gear 307 and the gear part 308 are both rotatably connected in the swinging adaptation groove 113. When the guide column 110 is perpendicular to the ground and parallel to the driving lower rod 304, the electric suction cup 101 places the sheet body 6 into the feeding tray 3.

[0031] Preferably, when it is necessary to drive the feeding tray 3 to move, a sector gear 307 and a gear part 308 are provided, and the two mesh with each other. When the limit plate 112 rotates, the gear part 308 is synchronously driven to rotate, thereby driving the sector gear 307 to rotate, driving the lower driving upper rod 305 and the driving lower rod 304 to swing, and the guide telescopic rod 306 is telescopically adapted, thereby driving the feeding tray 3 to move, and the feeding work can be completed. Moreover, when the guide column 110 is perpendicular to the ground, the driving upper and lower rods are also perpendicular to the ground, and the feeding tray 3 is directly below the limit plate 112, and the electric suction cup 101 can put the sheet body 6 into the feeding tray. 3, then the electric suction cup 101 resets, and the limit plate 112 also rotates accordingly, thereby driving the feeding tray 3 to feed the sheet body 6 into the transmission roller 501, and then the electric suction cup 101 sucks the next sheet body 6, and when it moves to the feeding tray 3, it also synchronously drives the feeding tray 3 to move and reset, and receive the new sheet body 6. That is to say, during the movement of the electric suction cup 101 to pick up and discharge materials, the feeding tray 3 is synchronously controlled to feed and reset, so that when the electric suction cup 101 picks up materials, the feeding tray 3 feeds materials, and when the electric suction cup 101 discharges materials, the feeding tray 3 resets and receives them. The two have good synchronization, high degree of automation, and cost saving.

[0032] One end of any transmission roller 501 is fixedly connected to pulley 1 502, a transmission groove is opened on the outside of the feeding chamber 1, pulley 1 502 is rotatably connected in the transmission groove, one end of pulley 1 502 is connected to pulley 2 503, and pulley 2 503 is fixedly connected to the turntable 107.

[0033] Preferably, the turntable 107 drives the transmission roller 501 to rotate through the belt transmission mechanism, so that the two rotate synchronously. When the feeding tray 3 feeds the sheet body 6 into the transmission roller 501, the turntable 107 rotates, driving the electric suction cup 101 to reset, and at the same time drives the transmission roller 501 to rotate, thereby driving the current sheet body 6 to be transported to the punch body 7 to complete the loading work. That is to say, through the rotation of the turntable 107, the electric suction cup 101 is screened and loaded, and the transmission roller 501 is also driven to transport the sheet body 6, realizing the fully automatic screening and loading of the sheet body 6, which is highly practical.

[0034] One end of the push plate 405 is fixedly connected to a plurality of push rods 407, which penetrate through the supporting vertical plate 401 and slideably cooperate with it, one end of the push rod 407 is provided with a T-shaped plate 406, and the lower end of the T-shaped plate 406 is fixedly connected to a plurality of arc-shaped bars 408, the middle side of the connecting column 108 is fixedly connected to a fixing ring, and the outer side of the fixing ring is fixedly connected to a driving bar 114, and the driving bar 114 corresponds to the arc-shaped bar 408.

[0035] Preferably, when it is necessary to drive the push plate 405 to push and support the sheet body 6, the connecting column 108 is rotated to drive the driving bar 114 to rotate. When the driving bar 114 contacts the arc bar 408, the arc bar 408 and the T-plate 406 are pushed to move, and the push rod 407 and the push plate 405 can be pushed to move, so that several sheet bodies 6 are moved toward the open end and kept in a vertical state, thereby facilitating the electric suction cup 101 to contact and absorb the outer sheet body 6, thereby realizing the function of automatic pushing. The displacement of the push plate 405 and the displacement of the electric suction cup 101 are both driven by the rotation of the turntable 107. When the turntable 107 rotates one circle, the push plate 405 is driven to move a stroke, and the electric suction cup 101 also moves a stroke when picking up the material, so that the push plate 405 pushes the material while the electric suction cup 101 picks up the material, thereby just supporting the sheet body 6, maintaining the tightness of the electric suction cup 101 sucking and fitting, and improving the stability of picking up the material.

[0036] The push rod 407 passes through the T-shaped plate 406 and slides with it. The outer end of the push rod 407 is fixedly connected with an end cover. The outer side of the push rod 407 is sleeved with a spring member. The two ends of the spring member are respectively connected to the T-shaped plate 406 and the supporting vertical plate 401.

[0037] Preferably, in order to facilitate the staff to re-place the sheet material body 6 in the storage chamber 4, the pushing plate 405 needs to be retracted into the storage groove, and when the sheet material body 6 in the storage chamber 4 is gradually sucked and loaded, the overall thickness of the remaining sheet material body 6 in the storage chamber 4 becomes smaller and smaller. In order to prevent the pushing plate 405 from only being able to push a fixed number of sheet material bodies 6 of thickness, a friction force is set between the pushing rod 407 and the T-shaped plate 406. In the initial state, the pushing plate 405 is retracted into the storage groove, and the end cover is in contact with the T-shaped plate 406. The turntable 107 rotates, and the driving bar 114 pushes the T-shaped plate 406 to move. The friction force drives the pushing rod 407 and the pushing plate 405 to move, thereby pushing the sheet material body 6 to be arranged and aligned. When there are more sheet material bodies 6 in the storage chamber 4, the pushing rod 407 is used to push the sheet material body 6 to be retracted. After the material plate 405 pushes the sheet material body 6 for a certain distance, it stops moving, and the push rod 407 cannot move any further. At this time, the driving bar 114 is still pushing the T-shaped plate 406 to move. When the driving force is greater than the friction force, the T-shaped plate 406 will be displaced relative to the push rod 407 to adapt until the driving bar 114 rotates to a range out of the arc strip 408. Then, under the resetting action of the spring member, the push plate 405 can be retracted into the storage groove, and the end cover is in contact with the T-shaped plate 406, so that it is convenient for the staff to add materials during this period. Moreover, as the number of sheet material bodies 6 in the storage chamber 4 becomes smaller and smaller, the displacement distance of the T-shaped plate 406 relative to the push rod 407 becomes smaller and smaller, and the sheet material bodies 6 of different numbers in the storage chamber 4 can be arranged and aligned, with good adaptability.
