Description

Technical Field

[0001] The utility model relates to the field of stamping equipment, in particular to a guiding mechanism for conveying stamping blanks. Background Art

[0002] During the stamping and blanking process, the blank needs to be transported to enable the subsequent punching process. In actual production, the same stamping and blanking die needs to be used for blanks of different roll widths. Due to the different roll widths of the blanks, the width of the guide mechanism used to feed the die needs to be adjusted accordingly to ensure that the adjusted guide mechanism can adapt to the new roll width of the blank, thereby ensuring that the blank can be smoothly transported to the next punching and blanking station.

[0003] In the existing conveying process, the guide mechanism mainly realizes the conveyance of the blank through the middle roller bracket and the universal roller. Among them, the middle roller bracket is arranged downstream of the universal roller along the conveying direction of the stamped blank. The blank is conveyed to the punching processing area after being conveyed by the universal roller and the middle roller bracket. Although the existing structure is equipped with corresponding sliding tables on both sides of the middle roller bracket, and the rollers on the top of the sliding tables can provide auxiliary support for the side parts of both sides of the blank, the spacing between the sliding tables needs to be manually adjusted when encountering blanks of different roll widths. Not only can the adjustment accuracy not be guaranteed, but the manual adjustment is also time-consuming and reduces production efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a guide mechanism for conveying stamping blanks which can accurately adjust the distance between the sliding tables on both sides of the middle roller bracket, thereby improving production efficiency.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a guiding mechanism for conveying stamping blanks, including a middle roller bracket and a universal roller, the middle roller bracket is arranged downstream of the universal roller along the conveying direction of the stamping blank; including two sliding platforms, the two sliding platforms are respectively arranged on the left and right sides of the middle roller bracket, and rollers are arranged on the top of the sliding platform, including a screw pair, the two sliding platforms are connected by a screw pair, the sliding platform and the screw pair are threaded together, the spiral rotation direction of the part of the screw pair located on the left side of the middle roller bracket is the forward rotation direction, and the spiral rotation direction of the part of the screw pair located on the right side of the middle roller bracket is the reverse rotation direction; including a screw pair driving mechanism, the screw pair driving mechanism drives the screw pair to rotate forward or reverse.

[0006] Furthermore, the screw pair driving mechanism includes a rotating adjustment handwheel, which is fixedly connected to one end of the screw pair, and the rotating shaft of the rotating adjustment handwheel is coaxially arranged with the axis of the screw pair.

[0007] Furthermore, the screw pair driving mechanism includes a scale reference platform, which is arranged along the extension direction of the screw pair and is fixedly arranged on the lower die base.

[0008] Furthermore, the screw pair driving mechanism includes a servo drive motor, which is arranged at the other end of the screw pair, and the output shaft of the servo drive motor is coaxially arranged with the axis of the screw pair.

[0009] Furthermore, it includes a main grating and a scanning head, the scanning head is fixedly arranged on the sliding table, the main grating is fixedly arranged on the scale mounting seat of the lower mold base, and the scanning head is electrically connected to the servo drive motor.

[0010] Furthermore, it includes a sliding guide rail seat and a sliding guide rail bar. The bottom of the sliding platform is fixedly set on the sliding guide rail seat. The sliding guide rail seat includes a bottom groove. The bottom groove can be slidably set on the sliding guide rail bar. The extension direction of the sliding guide rail is parallel to the extension direction of the screw rod pair.

[0011] Furthermore, the distances between the two sliding platforms and the middle roller bracket are consistent.

[0012] The beneficial effect of the present invention is that, in actual use, when it is necessary to adjust the distance between the two sliding tables to adapt to the new roll width of the blank, that is, the new width of the blank, it is only necessary to drive the screw pair to rotate through the screw pair driving mechanism. For example, when the screw pair driving mechanism drives the screw pair to rotate forward, the distance between the two sliding tables is reduced; when the screw pair driving mechanism drives the screw pair to reverse, the distance between the two sliding tables is expanded. By adjusting the distance between the two sliding tables by rotating the screw pair, the accuracy of the adjustment can be significantly improved, and at the same time, the efficiency of the adjustment is greatly increased. The present invention is particularly suitable for use in the process of conveying stamping blanks. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 、 Figure 2 and Figure 3 The figure shows an embodiment of a guide mechanism for conveying stamping blanks. In actual use, the blank 7 is first placed above the universal roller 8. A plurality of universal rollers 8 are arranged at intervals along a straight line parallel to the screw pair 10. The arrangement direction of the universal rollers 8 is also consistent with the rolling width direction of the blank 7, that is, the width direction. The universal roller 8 first conveys the blank 7 toward the middle roller bracket 15. For the blank 7 conveyed to the middle roller bracket 15, since the spacing between the sliding tables 4 has been set, the sliding tables 4 arranged on the left and right sides of the middle roller bracket 15 can just support the side edges of the blank 7 through their respective rollers 5, thereby constructing a support structure formed by the middle roller bracket 15 and the two rollers 5 to ensure that the blank 7 continues to be conveyed forward smoothly. The bottom of the sliding platform 4 is fixedly set on the sliding guide rail seat 3. The sliding guide rail seat 3 includes a bottom groove. The bottom groove can be slidably set on the sliding guide rail 2. The extension direction of the sliding guide rail 2 is parallel to the extension direction of the screw pair 10.

[0019] The sliding platforms 4 are arranged on the left and right sides of the middle roller bracket 15 and are connected by a screw pair 10. Figure 1 As shown, the screw pair 10 passes through the through hole at the bottom of the middle roller bracket 15, and the middle roller bracket 15 is arranged in the middle position of the two sliding platforms 4. The spacing between the two sliding platforms 4 and the middle roller bracket 15 is consistent, so that it is convenient to adjust the two sliding platforms 4 synchronously with the middle roller bracket 15 as the adjustment reference, ensuring that no matter how much the spacing between the sliding platforms 4 is, the middle roller bracket 15 can provide support for the center position of the blank 7 to prevent the center position of the blank 7 from collapsing downward. Among them, the sliding platform 4 and the screw pair 10 are threadedly matched, so that by rotating the screw pair 10, the sliding platform 4 can be moved along the axis direction of the screw pair 10. In order to achieve that the sliding platforms 4 can move toward each other and get closer or move away from each other when the screw pair 10 rotates, it is necessary to ensure that the spiral rotation direction of the part of the screw pair 10 located on the left side of the middle roller bracket 15 is the positive rotation direction, and the spiral rotation direction of the part of the screw pair 10 located on the right side of the middle roller bracket 15 is the reverse rotation direction. By setting the two spiral rotation directions of the screw pair 10 to opposite directions, the movement directions of the two sliding tables 4 are opposite no matter how the screw pair 10 rotates, thereby reducing or increasing the distance between the two sliding tables 4.

[0020] As for the driving mode of the screw pair 10, the corresponding screw pair driving mechanism can be selected for driving, thereby allowing the screw pair 10 to realize forward or reverse rotation. As a preferred method of the screw pair driving mechanism, Figure 1 and Figure 3 As shown, the screw pair driving mechanism can choose to rotate the adjustment handwheel 6. The rotation adjustment handwheel 6 is fixedly connected to one end of the screw pair 10, and the rotation axis of the rotation adjustment handwheel 6 is coaxially arranged with the axis of the screw pair 10. By rotating the rotation adjustment handwheel 6, the screw pair 10 can be rotated along the rotation direction of the rotation adjustment handwheel 6, thereby adjusting the distance between the two sliding tables 4. Among them, when manually rotating the rotation adjustment handwheel 6, as a position reference for the movement of the sliding table 4, a scale reference table 9 can be optionally added. The scale reference table 9 is set along the extension direction of the screw pair 10, and the scale reference table 9 is fixedly set on the lower mold base 1. By observing the relative position between the sliding table 4 and the scale reference table 9, the displacement of the sliding table 4 can be judged, thereby realizing accurate position adjustment of the sliding table 4.

[0021] As another preferred method of the screw pair driving mechanism, the screw pair 10 can be driven forward or reversely by a servo drive motor 11, wherein the servo drive motor 11 is arranged at the other end of the screw pair 10, and the output shaft of the servo drive motor 11 is coaxial with the axis of the screw pair 10. Figure 1 and Figure 2 As shown, the rotary adjustment hand wheel 6 can be set at the left end of the screw pair 10, and the servo drive motor 11 can be set at the right end of the screw pair 10, so that manual adjustment and electric adjustment can be applied to the drive of the screw pair 10 at the same time. Similarly, during electric adjustment, in order to achieve accurate adjustment, it is also necessary to set a corresponding scale as a reference for the displacement. The following solution can be selected: including a main grating 13 and a scanning head 14, the scanning head 14 is fixedly set on the sliding table 4, the main grating 13 is fixedly set on the scale mounting seat 12 of the lower mold base 1, and the scanning head 14 is electrically connected to the servo drive motor 11. Figure 1 As shown, when relative displacement occurs between the main grating 13 and the scanning head 14, the scanning head 14 converts the read displacement into an electrical pulse signal and feeds it back to the servo system. The servo system controls the rotation direction and rotation time of the servo drive motor 11 according to the adjustment needs, thereby adjusting the two sliding tables 4 to the required spacing, thereby adapting to blanks 7 with different roll widths.
