Description

Technical Field

[0001] The utility model relates to the technical field of metal sheet processing, in particular to a feeding device for metal sheets of a punching press provided with a deviation rectifying and guiding structure. Background Technique

[0002] A punching press, also known as a stamping press, mainly performs stamping processing on metal sheets so as to form workpieces with required shapes and states. During the use of an automatic punching press, a feeding mechanism is required to cooperate to convey the sheets. However, due to differences in the specifications of some sheets, the sheets are offset and misaligned during conveyance, affecting subsequent stamping processing.

[0003] The utility model with the publication number of CN221342709U discloses a deviation rectifying device for a steel sheet feeder. The deviation situation of the conveying mechanism is monitored in real time through a ranging module. If the conveying mechanism deviates, the ranging module sends the deviation amount to the translation module, and the translation module controls the conveying mechanism to move a corresponding distance to align the steel coil sheet.

[0004] However, the following problems still exist in the actual use of the above-mentioned feeding deviation rectifying mechanism for sheet processing: Although the deviation rectifying and conveying of the sheets are achieved through the deviation rectifying mechanism and the conveying mechanism, such conveying mechanisms cover a large area and require a long length for conveying the sheets. At the same time, a relatively precise recognition mechanism is adopted, and manual data adjustment is required when recognizing sheets of different specifications, which is not conducive to integrated use, and the sheet storage efficiency is not high.

[0005] Therefore, we propose a feeding device for metal sheets of a punching press provided with a deviation rectifying and guiding structure to solve the problems raised above. Content of the Utility Model

At the same time, a relatively precise recognition mechanism is adopted, and manual data adjustment is required when recognizing sheets of different specifications, which is not conducive to integrated use, and the sheet storage efficiency is not high.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A feeding device for metal sheets of a punching press provided with a deviation rectifying and guiding structure includes a feeding box body and a storage cavity opened inside the feeding box body.

[0008] It further includes: A deviation rectifying mechanism is arranged inside the feeding box body, and the deviation rectifying mechanism includes a deviation rectifying contact plate which is slidably arranged on the left and right sides inside the feeding box body.

[0014] Preferably, the adjusting mechanism includes a guiding sleeve, and the guiding sleeve is fixedly installed below the front of the feeding box body, and the inside of the guiding sleeve is threadedly connected to the upper end of the lifting threaded rod, and by rotating the lifting threaded rod, the height limiting slide plate is driven to lift, so as to adjust the height of the discharge chute opening.

[0015] Preferably, the feeding mechanism includes a driving motor, and the driving motor is fixedly installed at the rear of the bottom surface of the feeding box body, and the driving motor is fixedly connected to the rear end of the reciprocating threaded rod, and the outer wall of the reciprocating threaded rod is threadedly connected with a guiding slider, and a one-way limiting post is fixedly arranged at the rear of the top surface of the guiding slider.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows: the punching metal sheet feeding device provided with a deviation correction guide structure performs interference correction for sheets of different specifications through the deviation correction mechanism inside the feeding box to prevent deviation during storage, and at the same time, the adjustment mechanism cooperates with the feeding mechanism to push the bottom sheet to the outside, and the subsequent stamping process is carried out after the sheet is transported out of the feeding box.

[0018] 1. The plate is placed in the feeding box, and then the rotating bidirectional threaded rod drives the threaded sleeve and the correcting bracket to move, and the correcting bracket drives the correcting plates on the left and right sides of the feeding box to move in the opposite direction, thereby changing the distance between the correcting plates on both sides, and realizing regular positioning of the plate, avoiding misalignment of the plate during storage and affecting subsequent conveying and processing.

[0019] 2. Rotate the lifting threaded rod above the height limiting slide to make it threadedly connected with the guide sleeve.

The lifting rod of the height limiting slide changes the range of the discharge slot so that the bottom end height of the height limiting slide is higher than the height of the lowest plate and lower than the top height of the second to last plate, so that the lowest plate can be transported to the outside during the subsequent feeding process.

[0020] 3. The reciprocating threaded rod drives the guide slider and the feeding resistance rod to move. During the backward movement, the feeding resistance rod rotates by resisting the lowest plate. When the feeding resistance rod moves forward, it resets and flips, and the top end resists the rear end of the lowest plate. The feeding resistance rod is limited by a one-way limiting column to drive the lowest plate to move forward and be transported out of the feeding box for subsequent stamping processing.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0029] Please refer to Figures 1 - 6 , the present invention provides the following technical solutions:

[0030] Embodiment 1: In order to solve the problems existing in the actual use of metal sheets of different specifications, therefore, in this embodiment, through the following technical solutions, a punching metal sheet feeding device with a deviation correction and guiding structure includes a feeding box body 1 and a stock storage cavity 2 opened inside the feeding box body 1; a deviation correction mechanism is arranged inside the feeding box body 1, and the deviation correction mechanism includes a deviation correction contact plate 3, and the deviation correction contact plate 3 is slidably arranged on the left and right sides inside the feeding box body 1.

[0031] The deviation correction mechanism includes a bidirectional threaded rod 6, and the bidirectional threaded rod 6 is rotatably arranged below the rear part of the feeding box body 1 through a bearing, and the outer walls of the left and right sides of the bidirectional threaded rod 6 are both threadedly connected with threaded sleeves 7, and the outer walls of the left and right threaded sleeves 7 are both fixedly connected to the rear end of the deviation correction support 8; the upper ends of the deviation correction contact plates 3 included in the deviation correction mechanism are both distributed in an outwardly inclined structure, and the bottom ends of the left and right deviation correction contact plates 3 are both in sliding contact with the bottom surface of the feeding box body 1, and the outer walls of the left and right deviation correction contact plates 3 are both fixedly connected to the inner ends of the deviation correction support 8.

[0032] As Figures 1 - 3As shown, when it is necessary to adjust the range of the deviation rectifying mechanism inside the feeding box body 1 according to the specifications of the plate, first place the plate in the material storage cavity 2 opened inside the feeding box body 1, and then manually rotate the bidirectional threaded rod 6 arranged behind the feeding box body 1, so that it drives the guiding threaded sleeve 7 and the deviation rectifying support 8 threadedly connected to the outer walls on the left and right sides to move in the opposite direction. Then, the deviation rectifying support 8 drives the deviation rectifying contact plate 3 at its inner end to move on the left and right sides inside the feeding box body 1, so that the deviation rectifying contact plate 3 abuts against the left and right ends of the plate, thereby realizing the regular limiting of the plate and avoiding the dislocation of the plate during the feeding and storage process, which affects the subsequent conveying and processing.

[0033] Embodiment 2: In order to solve the problems existing in the actual use of plates with different specifications, therefore, in this embodiment, the following technical solutions are adopted. Among them, an adjusting mechanism is arranged below the front of the feeding box body 1, and the adjusting mechanism includes a discharge slot 4, and the discharge slot 4 is opened below the front of the feeding box body 1; the adjusting mechanism includes a height limiting slide plate 9, and the left and right sides of the front of the height limiting slide plate 9 are fixedly connected to the bottom ends of the guiding slide rods 10, and the top ends of the guiding slide rods 10 on the left and right sides are slidably connected to the front of the feeding box body 1, and the middle upper part of the front of the height limiting slide plate 9 is rotatably connected to the bottom end of the lifting threaded rod 11; the adjusting mechanism includes a guiding sleeve 12, and the guiding sleeve 12 is fixedly installed below the front of the feeding box body 1, and the inside of the guiding sleeve 12 is threadedly connected to the upper end of the lifting threaded rod 11, and by rotating the lifting threaded rod 11, the height limiting slide plate 9 is driven to lift, so as to adjust the height of the discharge slot 4.

[0034] As Figure 1 、 Figure 4 shown, when it is necessary to change the height of the adjusting mechanism according to the thickness of the plate, manually rotate the lifting threaded rod 11 arranged on the front of the feeding box body 1. Then, the guiding sleeve 12 threadedly connected to the lifting threaded rod 11 is fixedly installed on the front of the feeding box body 1, so that the lifting threaded rod 11 drives the height limiting slide plate 9 at its bottom end to be adjusted in the up and down direction. At the same time, the movement of the height limiting slide plate 9 is limited by the guiding slide rods 10 on the left and right sides, and the range of the discharge slot 4 is changed by the lifting rod of the height limiting slide plate 9, so that the bottom height of the height limiting slide plate 9 is higher than the height of the lowermost plate and lower than the top height of the second-lowermost plate, so as to be able to convey the lowermost plate outward during the subsequent feeding process.

[0035] Embodiment 3: To solve the problems existing in the actual use of plates of different specifications, the following technical solutions are adopted in this embodiment. Specifically, a feeding mechanism is provided at the bottom of the feeding box body 1, and the feeding mechanism includes a reciprocating threaded rod 5, and the reciprocating threaded rod 5 is rotatably arranged at the center position below the feeding box body 1 through a bearing; the feeding mechanism includes a driving motor 13, and the driving motor 13 is fixedly installed at the rear of the bottom surface of the feeding box body 1, and the driving motor 13 is fixedly connected to the rear end of the reciprocating threaded rod 5. Moreover, a guiding slider 14 is threadedly connected to the outer wall of the reciprocating threaded rod 5, and a one-way limiting post 16 is fixedly arranged at the rear of the top surface of the guiding slider 14.

[0036] The feeding mechanism includes a feeding contact rod 15, and the bottom end of the feeding contact rod 15 is rotatably arranged on the top surface of the guiding slider 14 through a torsion spring, and the top end of the feeding contact rod 15 is slidably arranged inside the feeding box body 1, and the feeding contact rod 15 realizes one-way rotation through the one-way limiting post 16 at the rear.

[0037] As Figures 5 - 6 shown, when it is necessary to convey the plate, the driving motor 13 installed at the rear of the feeding box body 1 works to drive the fixedly connected reciprocating threaded rod 5 to rotate below the feeding box body 1, and then drives the threadedly connected guiding slider 14 and the feeding contact rod 15 rotatably connected to the top surface to move back and forth;

[0038] When the guiding slider 14 drives the feeding contact rod 15 at the top to move backward towards the feeding box body 1, the top end of the feeding contact rod 15 contacts the lowest plate inside the feeding box body 1. Under the resistance of the lowest plate, the feeding contact rod 15 is driven to flip forward, and then moves to the rearmost position without being affected by the plate. When the feeding contact rod 15 at the rear does not contact the plate, it flips upward and resets. Then its top end contacts the rear end of the lowest plate, and the one-way limiting post 16 limits the feeding contact rod 15 to ensure that it will not flip backward. At the same time, when moving forward, it drives the lowest plate in contact to move forward, and after being conveyed out of the feeding box body 1, subsequent stamping processing is carried out.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
