Description

Technical Field

[0001] The utility model relates to the technical field of automated processing, in particular to a three-in-one punching machine. Background Art

[0002] The three-in-one feeder is an automated device that integrates the three functions of unwinding, leveling and feeding, and is used for automated stamping processing. It has a high degree of automation and adaptability, can handle a variety of metal coils, and meet the stamping needs of different industries.

[0003] Specifically, the three-in-one feeder for punching machines improves the degree of automation, adapts to various production needs, saves labor costs, and significantly improves production efficiency. Usually only one person is needed to complete operations such as loading, feeding, guiding, debugging and mold testing, which greatly shortens the operation time. Moreover, the three-in-one feeder for punching machines integrates the three functions of uncoiling, leveling and feeding into one, which greatly reduces the floor space. Its floor space is about 50% of that of the traditional split stamping production line, which greatly saves the floor space of automated production.

[0004] In actual use, the sheet is punched by the punch press after being fed. The punch press stops unwinding and feeding the sheet when punching the sheet, and continues unwinding and feeding after punching. Therefore, the unwinding and feeding of the sheet are carried out intermittently, but in this process, the vibration generated by the punch press during punching will be transmitted to the subsequent sheet at the punching position, which can easily cause the sheet to shift or bend excessively to cause deformation; at the same time, in the process of conveying the sheet after unwinding, in order to prevent the feeding direction from deviating from the position of the mold on the punch press, the sheet needs to be corrected during transportation, but the existing correction mechanism needs manual adjustment when facing sheets of different widths, and is not convenient to use. In addition, the position of the correction mechanism is difficult to control. If it is too far away from the sheet, the correction effect is not ideal. If it is too close to the sheet, it is easy to cause the edge of the sheet to tilt. Utility Model Content

[0044] The correction device 5 is attached to both sides of the sheet 3, wherein

[0045] After the protection mechanism 4 is driven, the material sheet 3 is clamped to locally shape the material sheet 3;

[0046] The protection mechanism 4 is suitable for absorbing and isolating the vibration force when the punch body 1 is punching;

[0047] The correcting device 5 is suitable for correcting the sheet 3 according to the established conveying route. The protective mechanism 4 can clamp the sheet 3 at a position close to the punching area when the punch body 1 punches the sheet 3, so as to use the clamping force to relatively shape the subsequent part of the sheet 3 to prevent the sheet 3 from shifting or deforming. At the same time, it can absorb the vibration force generated during punching, thereby effectively blocking the transmission of vibration on the sheet 3 and further protecting the sheet 3. The correcting device 5 can automatically adjust the correction range according to the actual width of the sheet 3 currently in use, and the correcting device 5 simultaneously and synchronously approaches the sheet 3 from both sides of the sheet 3 until it reaches the appropriate correction position. There is no need for manual adjustment one by one, which greatly improves the actual convenience of use and effectively improves efficiency. When the correcting device 5 is in the optimal correction position, it can still provide the sheet 3 with corresponding lateral displacement space within the allowable movement range of the sheet 3, and has a certain flexibility, so as to ensure the stability of the sheet 3 while ensuring the correction effect, so as to prevent the edge of the sheet 3 from being damaged.

[0048] Optionally, the correction device 5 includes a long strip plate 51 installed on the three-in-one feeder 2 and below the material sheet 3, two groups of through grooves 52 provided on the long strip plate 51, two groups of sliding members 53 slidably installed on the long strip plate 51 through the two groups of through grooves 52, and the two groups of sliding members 53 are respectively located at two ends of the long strip plate 51, two groove plates 54 mirror-mounted on the two groups of sliding members 53, and the open ends of the two groove plates 54 are both facing the material sheet 3, abutments 55 respectively located in the two groove plates 54, two connected plates 56 respectively installed at the bottom of the two groups of sliding members 53, a positioning member 57 installed on the three-in-one feeder 2, an electric cylinder 58 installed on the positioning member 57 and below the two connected plates 56, and two cables 59 with one end connected to the two connected plates 56 and the other end connected to the output shaft of the electric cylinder 58;

[0049] The two abutment pieces 55 are respectively attached to two sides of the material piece 3;

[0050] The electric cylinder 58 is centrally located between the two connected plates 56. Under normal circumstances, the two abutments 55 are respectively attached to the left and right sides of the sheet 3, and the two groups of sliding members 53 are restricted and will not slide in the two groups of through grooves 52 when the electric cylinder 58 is not driven. Therefore, the two abutments 55 are fixed in the current position to continue to play a corrective role on the sheet 3. When the width of the sheet 3 used becomes smaller, the electric cylinder 58 is driven to retract its output shaft to pull down the two cables 59, so that the two cables 59 respectively pull the two groups of sliding members 53 toward the sheet 3 in the middle position through the two connected plates 56 at the same time and synchronously until it is found under real-time observation that the abutments 55 in the two groove plates 54 are attached to the left and right sides of the sheet 3, and then the driving of the electric cylinder 58 is stopped, thereby quickly re-completing the adjustment of the correction position of the sheet 3 after the width is reduced, ensuring that the feeding direction does not deviate from the mold position on the punch body 1, and at the same time, there is no need for manual adjustment one by one, which greatly improves the actual convenience of use and can effectively improve efficiency.

[0051] Optionally, the correction device 5 further includes two sets of first springs 591, one end of which is respectively connected to the inner walls of the two groove plates 54;

[0052] The other ends of the two groups of the first springs 591 are respectively connected to the backs of the two abutments 55, so that when the two abutments 55 are attached to the left and right sides of the sheet 3 to correct it, if the same sheet 3 has a slight size change, or due to various circumstances, the sheet 3 causes a certain degree of left and right lateral movement, the sheet 3 can compress a group of first springs 591 on the corresponding side, so that the corresponding abutments 55 retreat to adapt to the changes of the sheet 3, thereby forming a flexible elastic area, which effectively prevents the edge of the sheet 3 from being damaged due to the two abutments 55 being too tight against the sheet 3, thereby ensuring high-quality and stable conveying of the sheet 3; the length and stretching stroke of the two groups of first springs 591, that is, the movable range of the two abutments 55 is controlled within the movable range of the sheet 3 relative to the mold on the punch body 1, ensuring that the sheet 3 is not damaged during the conveying process while preventing excessive deviations between the conveying direction of the sheet 3 and the mold on the punch body 1 to affect the stamping.

[0053] Optionally, the protection mechanism 4 includes a scissor lift 41 provided on the punch body 1, a base pad 42 installed on the top of the scissor lift 41, a reference platform 43 installed on the punch body 1, a swing cylinder 44 provided on the reference platform 43, a swing arm 45 installed on the output shaft of the swing cylinder 44, and a pressing member 46 connected to the swing arm 45;

[0054] The base pad strip 42 abuts against the bottom surface of the sheet 3 , and the base pad strip 42 is close to the punching area of ​​the punch body 1 ;

[0055] The pressing member 46 is in contact with the surface of the sheet 3 and corresponds to the base pad 42. Before the punching machine body 1 punches the sheet 3, the swing cylinder 44 is driven to swing the pressing member 46 downward through the swing arm 45 until the pressing member 46 is completely pressed against the surface of the sheet 3, thereby clamping the portion of the sheet 3 close to the current punching area together with the base pad 42 and the pressing member 46, and then using this clamping force to relatively shape the subsequent parts of the sheet 3, effectively preventing the sheet 3 from shifting or deforming. The scissor lift 41 is an existing vertical lifting device, which ensures that the base pad 42 can be adjusted accordingly according to the feeding height of the three-in-one feeder 2 through the scissor lift 41, so as to ensure that the base pad 42 can be against the bottom surface of the sheet 3 and cooperate with the pressing member 46 to clamp the sheet 3.

[0056] Optionally, the pressing member 46 includes an upper strip 461 connected to the swing arm 45, two connecting strips 462 respectively installed at two edges of the bottom of the upper strip 461, and a rubber plate 463 installed on the two connecting strips 462;

[0057] The rubber plate 463 is in contact with the surface of the sheet 3, and the high elasticity of rubber is used to make the rubber plate 463 have the property of absorbing vibration, thereby ensuring that after the protection mechanism 4 clamps the sheet 3, the rubber plate 463 can absorb the vibration force during stamping, thereby effectively blocking the transmission of vibration on the sheet 3, and further protecting the sheet 3 from deformation or displacement.

[0058] Optionally, the correction device 5 also includes a middle plate 592 centrally installed at the bottom of the long strip 51, two sets of second springs 593 with one end respectively connected to the front and back sides of the middle plate 592 and the other end respectively connected to the two connected plates 56, and two guide tubes 594 mirror-mounted on the two connected plates 56. When the width of the used sheet 3 increases, the electric cylinder 58 is driven in the reverse direction to extend its output shaft outward, thereby loosening the two cables 59. After losing the restriction of the two cables 59, the two compressed sets of second springs 593 automatically rebound according to the tightness of the two cables 59, thereby synchronously pushing the two sets of sliding members 53 outward through the two connected plates 56 until the two abutments 55 reach a position in contact with the two sides of the sheet 3 and then stop driving the electric cylinder 58, thereby ensuring that the correction range can be automatically adjusted according to the actual width of the currently used sheet 3.

[0059] The two guide tubes 594 are respectively sleeved on the two cables 59, and the two cables 59 are respectively attached to the inner walls of the two guide tubes 594. The two guide tubes 594 are used to change the extension direction of the two cables 59, and guide a part of the two cables 59 to extend along the direction of the two groups of through grooves 52, thereby prompting the two cables 59 to be connected to the electric cylinder 58 at a larger angle as a whole, ensuring that after the electric cylinder 58 is driven, the two cables 59 can smoothly pull the two groups of sliding members 53 laterally through the two groups of through grooves 52.

[0060] Optionally, the protection mechanism 4 further includes a suspension frame 47 mounted on the side of the upper slat 461, and a distance sensor 48 invertedly mounted on the suspension frame 47, the distance sensor 48 is electrically connected to the swing cylinder 44, and the distance sensor 48 senses the distance between the pressing member 46 and the sheet 3 in real time, ensuring that when the rubber plate 463 is pressed tightly against the sheet 3, the distance sensor 48 can capture and transmit this information to the swing cylinder 44 in time, and control it to stop in time, so as to prevent the sheet 3 from being clamped by excessive clamping force;

[0061] The two abutments 55 are made of cold-rolled steel, which has a very high surface smoothness, thereby greatly reducing wear when correcting the sheet 3 or preventing jamming, thereby ensuring smooth conveyance of the sheet 3 .

[0062] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
