Description

Technical Field

[0001] This utility model relates to the field of cold press technology, specifically to a feeding device for a metal sheet cold press. Background Technology

[0002] Cold presses are important equipment in the processing of metal sheets. During the feeding process, the feeding effect of the feeding device is particularly important for the cold pressing effect of the metal sheet cold press. A search revealed that patent CN209812619U discloses an automatic feeding device for a door panel cold press. In operation, a door panel is placed on the feeding conveyor belt through the door panel loading port. The conveyor belt transports the door panel to the door panel feeding side of the cold press. Before the door panel enters the cold pressing table, it moves towards the table under the action of the feeding conveyor belt, first pushing open the second push plate, and then entering the cold pressing table. The second push plate returns to a horizontal position with the first push plate under the force of a torsion spring. At this time, by activating the cylinder, the cylinder's extension rod extends, pushing the first push plate along the slide groove and in the same direction as the extension rod. The second push plate also moves along the same direction as the first push plate. Under the action of the first pusher, the first pusher moves in the same direction as the telescopic rod. Under the pushing force of the second pusher, the door panel is further pushed away from the feeding conveyor belt. When the target position is reached, the telescopic rod of the cylinder is retracted by the control system, and the first pusher moves towards the feeding conveyor belt. This further drives the second pusher to move towards the feeding conveyor belt. In this way, if the friction between the cold-pressed plate and the conveyor belt is insufficient to push the two second pushers apart, the feeding jam may easily occur. At the same time, the two second pushers react on the cold-pressed plate for centering and limiting. Due to the friction between the conveyor belt and the plate, the feeding may tilt. Therefore, a feeding device for a cold press of metal plates is designed that is easy to flexibly center and limit, has low friction on the metal plate during the centering and limiting process, and has high feeding stability.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, this utility model provides a feeding device for a cold press of metal sheets, which has the following advantages:

[0014] This feeding device for a cold press of metal sheets facilitates the smooth transport of metal sheets during the feeding process via a guide rail. A traction mechanism pulls the metal sheets along the guide rail, while a limiting and correcting mechanism provides pre-traction correction. At least two sets of guide wheels on each side, along with limiting ring grooves, limit the metal sheet as it passes the first guide wheel, and correct it as it passes the second guide wheel. This ensures the metal sheet travels parallel to the guide rail. The guide wheels, the limiting ring grooves on both sides, and the guide rail minimize friction on the metal sheet during centering and limiting, further ensuring feeding stability. This feeding device for a cold press of metal sheets allows for flexible centering and limiting with minimal friction on the metal sheet and high feeding stability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1-5 A feeding device for a cold press of metal sheets includes a guide rail. Above the guide rail, along the guiding direction, a limit correction mechanism and a traction mechanism are arranged in sequence. The limit correction mechanism includes two symmetrically arranged side baffle assemblies. Each side baffle assembly includes a connecting plate 4 and at least two sets of guide wheels 6 arranged at the bottom of the connecting plate 4 and distributed in sequence along the guiding direction. Limiting annular grooves 7 are provided on both sides of the guide wheels 6. The guide wheels 6 are rotatably connected to the bottom of the connecting plate 4 through a rotating seat 5. The device also includes an adjustment assembly that drives the two side baffle assemblies to feed towards the center.

[0024] Specifically, the guide track includes a guide frame 1, on which multiple guide rollers 2 are rotatably connected to the guide frame 1 at intervals. The arrangement of multiple guide rollers 2 facilitates smoother material conveying of metal sheets on the multiple guide rollers 2.

[0025] Specifically, the adjustment assembly includes an adjustment track 3 fixedly mounted above the guide frame 1 via two support legs 20. A bidirectional screw 8 is rotatably connected to the adjustment track 3 via an adjustment motor 10. The two sides of the bidirectional screw 8 are symmetrically threaded with adjustment sliders 9 that slide and guide the adjustment track 3. The tops of the two connecting plates 4 are fixedly connected to the bottoms of the adjustment sliders 9. When the adjustment motor 10 is started, its output shaft rotates clockwise or counterclockwise, which drives the bidirectional screw 8 to rotate clockwise or counterclockwise. This drives the two adjustment sliders 9 to move towards the center or to the sides, thereby driving the two sets of side stop assemblies on both sides to move towards the center or to the sides, thus facilitating the limit correction of metal plates of different widths.

[0026] Specifically, the traction mechanism includes a traction motor 13 fixedly mounted on the bottom of the guide frame 1 via a lower bracket 12. Two adjacent sets of guide rollers 2 away from the limit and alignment mechanism have traction ring grooves in their middle sections. A drive roller 14 is fixedly mounted on the output shaft of the traction motor 13. The drive roller 14 is connected to the two traction ring grooves via a transmission assembly 15. The bottom surface of the lower bracket 12 is flush with the bottom surface of the support leg 20. Starting the traction motor 13 causes the drive roller 14 to rotate. Through the transmission assembly 15, two of the guide rollers 2 rotate, thus traction is applied to the metal sheet passing through these two guide rollers 2. The flush alignment of the bottom surface of the lower bracket 12 with the bottom surface of the support leg 20 provides overall support and increases overall stability. Furthermore, the transmission assembly 15 can be a sprocket and chain or belt and pulley transmission, and the top of the transmission assembly 15 is lower than the top of the guide roller 2.

[0027] Specifically, it also includes a roller pressing assembly above two traction ring grooves. The roller pressing assembly includes a lifting drive cylinder 16 vertically fixed on the guide frame 1 via an upper hanger 11. A lifting plate 17 is fixedly installed on the bottom output shaft of the lifting drive cylinder 16. Multiple pressure rollers 18 are horizontally spaced at the bottom end of the lifting plate 17 and are parallel to the guide rollers 2. The lifting drive cylinder 16 can easily drive the lifting plate 17 and multiple pressure rollers 18 to move up and down as a whole. When moving downward, the multiple pressure rollers 18 can press the metal plate passing through the guide ring groove from the top. In addition, the setting of the pressure rollers 18 can also facilitate the top limit with the traction of the traction mechanism, thereby improving the stability of traction.

[0028] Specifically, a guide rod 19 is fixedly installed on the lifting plate 17, which slides vertically with the upper hanger 11. The lifting stability of the lifting plate 17 is improved by setting the guide rod 19.

[0029] In use, the metal sheet is placed on the guide rail from the side of the limiting and straightening mechanism, and then pushed towards the side of the limiting and straightening mechanism. When it passes the first guide wheel 6, the side blocking components on both sides are moved towards the middle by the adjustment mechanism, so that the guide wheels 6 on both sides center and limit the metal sheet. Then, it passes the second guide wheel 6 to ensure the straightening of the metal sheet. Then, when it passes the traction mechanism side, it is pulled and fed by the traction mechanism.
