Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a plate conveying device on a shearing machine. Background Technology

[0002] A cross-cutting machine is a piece of equipment used to cut sheet metal. It is commonly used in the transformer manufacturing industry to cross-cut silicon steel sheets.

[0003] In existing cross-cutting machines, the transfer process of sheet metal is mostly done manually. That is, the sheet metal needs to be pushed to the cutting station manually at the feeding end of the cross-cutting machine head. After cutting, the finished sheet metal is then taken out and stacked manually. This feeding and discharging method is not only labor-intensive, but also difficult to control the feeding and discharging rhythm, which affects the processing efficiency. At the same time, manual operation may also cause scratches and bumps on the surface of the sheet metal, reducing the finished product qualification rate. Therefore, it needs to be improved.

[0028] like Figures 1-4As shown, a sheet metal conveying device on a cross-cutting machine includes a cross-cutting machine table 11, a cross-cutting head 12 is provided on the cross-cutting machine table 11, and a sheet metal export mechanism and a sheet metal import mechanism are respectively provided on the left and right sides of the cross-cutting machine table 11. The sheet metal imported into the cross-cutting head 12 by the sheet metal import mechanism is processed by the cross-cutting head 12 and then exported to the left by the sheet metal export mechanism.

[0029] Specifically, such as Figure 3 As shown, the plate-introducing mechanism includes two first guide plates 21 distributed front to back, and the first guide plates 21 are provided with first guide grooves for accommodating and guiding the plates on their sides that are close to each other.

[0030] like Figure 2 and Figure 4 As shown, the plate ejection mechanism includes two second guide plates 31 distributed front to back and a drive box 32. Two drive rollers 33 distributed vertically are rotatably connected inside the drive box 32, and a first motor 34 is mounted on the drive box 32 to drive the two drive rollers 33 to rotate in opposite directions. The gap between the two drive rollers 33 is adapted to the thickness of the plate. One end of the second guide plate 31 is provided with an extension plate 35 extending into the drive box 32 and close to the gap between the drive rollers 33. The extension plate 35 and the second guide plate 31 are provided with a second guide groove.

[0031] The plate will move to the left between the two first guide plates 21 and along the first guide groove until it enters the cross-cutting head 12. The plate that has been cross-cut in the cross-cutting head 12 will be clamped between the drive rollers 33 and driven by the drive rollers 33 to continue moving to the left, so that the plate can be discharged through the second guide groove in the second guide plate 31.

[0032] In the above embodiment, the two drive rollers 33 can be connected by a gear set, and the output shaft of the first motor 34 is directly connected to one of the drive rollers 33, so that the two drive rollers can rotate in opposite directions.

[0033] Furthermore, in the above embodiments, the sheet metal needs to be manually fed when entering the first guide groove. To achieve an automated feeding process, such as... Figure 3 As shown, the plate feeding mechanism also includes a feeding drive assembly, which includes two mounting plates 25 distributed front to back and fixed on the cross-cutting machine table 11. Two driven wheels 26 and one driving wheel are rotatably connected between the two mounting plates 25. The driven wheels 26 and the driving wheel are connected together by a feeding belt 27. A third motor 28 for driving the driving wheel to rotate is provided on the mounting plate 25.

[0034] The feeding belt 27 is tensioned into an inverted triangular shape and is positioned between the two first guide plates 21. The upper edge of the feeding belt 27 is higher than the mounting plate 25 and higher than the lower edge of the first guide groove.

[0035] With the above settings, when the third motor 28 is powered on, it can drive the drive wheel to rotate and cooperate with the driven wheel 26 to drive the feeding belt 27 to move. During this process, the feeding belt 27 can drive the plate installed in the first guide groove to move to the left through friction and enter the cross-cutting head 12.

[0036] In a third embodiment of the board conveying device on the cross-cutting machine, in order to enable the board inlet mechanism and the board outlet mechanism to adapt to boards with different front and rear widths and increase the applicability of the board conveying device on the cross-cutting machine, the board inlet mechanism further includes a slide block 22 fixed on the cross-cutting machine table 11, and two slide plates 23 are slidably connected on the slide block 22, and the two first guide plates 21 are respectively fixed on the two slide plates 23;

[0037] The front and rear ends of the slide block 22 are also provided with bosses, and a first threaded shaft is rotatably connected between the two bosses. A second motor 24 for driving the first threaded shaft to rotate is mounted on the bosses. The first threaded shaft is machined with two threads with opposite directions and respectively connected to the two slide blocks 23.

[0038] like Figure 4 As shown, the plate ejection mechanism also includes two vertical plates 36 fixed on the shearing machine table 11 and distributed front to back. A slide rod 37 and a second threaded shaft are connected between the two vertical plates 36. Two slide tables 38 are slidably connected on the slide rod 37. Two second guide plates 31 are respectively fixed on the two slide tables 38. Two threads with opposite directions are machined on the second threaded shaft and are respectively connected to the two slide tables 38. A fourth motor 39 for driving the second threaded shaft to rotate is also installed on the vertical plate 36.

[0039] With the above settings, the operator can control the rotation of the first threaded shaft through the second motor 24, control the two slide plates 23 to move towards each other, and adjust the distance between the two first guide plates 21. This distance determines the front and rear width of the board that is adapted to the board conveying device on the shearing machine.

[0040] Similarly, the operator can control the rotation of the second threaded shaft through the fourth motor 39, control the two slides 38 to move towards each other, and adjust the distance between the two second guide plates 31 to adjust the front and rear width of the adapted plate.

[0041] In addition, in this embodiment, the first threaded shaft also passes through the mounting plate 25 and is rotatably connected to the mounting plate 25 to increase the structural strength of the plate introduction mechanism. Two slide rods 37 are provided and are connected to the slide table 38.

[0042] To facilitate material loading and unloading, the right edges of the lower sides of the first guide groove and the second guide groove are chamfered to form a compensating slope, so that the plates can be inserted into the first guide plate 21 in the plate inlet mechanism and the second guide plate 31 in the plate outlet mechanism.

[0043] Furthermore, during the process of the staff moving the plate to enter the first guide plate 21, the left end of the plate will inevitably droop due to gravity. In order to prevent the drooping left end of the plate from pressing the feed belt 27 into deformation and then hitting the mounting plate 25, a groove 40 is provided in the upper side of the mounting plate 25. The left and right positions of the groove 40 correspond to the right edge of the first guide plate 21, ensuring that the plate will not contact the mounting plate 25 when it is close to the first guide plate 21.

[0044] It should be noted that the heights of the first guide plate 21 and the second guide plate 31 must be adapted to the height of the processing platform inside the shear head 12 in order to achieve stable feeding and discharging of the material into the shear head 12.

[0045] The structure of the shear head 12 is a conventional solution in the prior art, and the blades inside can move up and down to cut the plate.

[0046] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0047] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
