Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a punching sheet centering device. Background Art

[0002] Metal sheets are flat sheets formed by pouring metal and pressing it after cooling. Metal sheets are stamped into workpieces of different shapes for use. Stamping is a forming method that uses a press and a die to apply external force to sheets, strips, pipes, and profiles to cause plastic deformation or separation, thereby obtaining workpieces (stampings) of the desired shape and size.

[0003] At present, the multi-station stamping line uses feeding equipment and stamping machines in combination. For metal sheets, the sheets are usually placed on a conveyor belt and transported to the stamping machine to complete the stamping of the sheets. Since the angle and position of the sheets on the conveyor belt are usually not uniform, in order to facilitate the subsequent clamps to accurately grasp the sheets, the function of the sheet centering device of the multi-station stamping line is to center the sheets on the feeding belt conveyor, so that the three-coordinate clamp can accurately grasp the sheets, thereby ensuring that the sheets are accurately transferred to the first-sequence mold.

[0004] The X-axis direction is set as the logistics direction of the material on the conveyor belt. In the prior art, the centering device for adjusting the position of the material in the Y-axis direction is usually provided with two independently controlled degrees of freedom in the Z direction and the Y direction. In the centering process, in order to ensure the centering quality, the actions are usually completed in the Z-axis and Y-axis directions in sequence, and then the Y-axis and Z-axis are reset in sequence after the actions are completed. The movement time of the centering device is too long, which reduces the centering rate of the material in the Y-axis direction. Utility Model Content

[0005] The utility model aims at the problems in the prior art and provides a punching sheet centering device for a punching line, thereby solving the problems in the prior art.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A device for centering a stamping sheet comprises a fixed base, a mounting frame is arranged on the base, a hinge shaft is arranged on the mounting frame, a centering piece is hinged on the hinge shaft, the upper end of the centering piece is a centering end for abutting against a sheet, a first hinge hole and a second hinge hole are arranged on the lower end of the centering piece, the first hinge hole is hinged to the hinge shaft, and the centering device also comprises a lifting mechanism, one end of the lifting mechanism is hinged on the mounting frame, the other end of the lifting mechanism is hinged to the second hinge hole, and the lifting end can be lifted and lowered on one side of the hinge shaft. Through the centering piece and the lifting mechanism, when the sheet needs to be abutted and centered, the lifting mechanism rises, so that the centering piece rotates with the hinge shaft as the axis, and the upper end of the centering piece moves in the Y-axis direction and the Z-axis direction, so as to realize rapid abutment and centering of the sheet, and improve the centering rate of the sheet in the Y-axis direction.

[0008] Preferably, the lifting mechanism includes a cylinder whose lower end is hinged on the mounting frame, and an ear seat is connected to the upper end of the cylinder, and the ear seat is hinged to the second hinge hole through the first pin. The provided cylinder can quickly complete the rising and falling actions of the lifting mechanism, that is, can quickly realize the centering action of the sheet, further improving the centering rate of the sheet in the Y-axis direction.

[0009] Preferably, a bent plate is fixedly provided at the fixed end of the cylinder, and both ends of the bent plate are fixed to the mounting frame through a second pin shaft, and a first wear-resistant plate cooperating with the second pin shaft is provided on the outer end surface of the mounting frame. By providing the bent plate and the first wear-resistant plate, the cylinder will swing with the action during the operation of the lifting mechanism, and the first wear-resistant plate provided at this time can prolong the wear time between the lifting mechanism and the mounting frame, thereby increasing the service life of the equipment.

[0010] Preferably, the mounting frame is slidably arranged on the base, the base is provided with a guide rail, and the mounting frame is provided with a locking mechanism, one end of which can clamp the guide rail. Through the provided guide rail and locking mechanism, during the centering process of the sheets of different sizes, the clamping mechanism can be released, and then the position of the mounting frame can be appropriately adjusted to adapt to the centering action of the sheets of new sizes.

[0011] Preferably, the locking mechanism includes a clamping plate fixed to the mounting frame, a first locking block is fixed to one side of the clamping plate, a second locking block is also provided on the other side of the clamping plate, and the locking mechanism also includes a locking handle and a screw, one end of the screw passes through the first locking block and is connected to the locking handle, and the other end is threadedly connected to the second locking block.

[0012] Preferably, a ruler is also provided on the base, and a pointer is also provided on the locking mechanism. Through the provided ruler and pointer, the size of the mounting seat adjustment can be calculated according to the length difference of the sheet in the Y-axis direction during the centering process of the sheets of different sizes. At this time, the provided ruler and pointer enable the staff to accurately complete the position change of the mounting frame with only one adjustment.

[0013] Preferably, the bracket is also provided with a right angle bracket, and a limit block capable of abutting against the mounting bracket is installed on the right angle bracket. The limit block can prevent the mounting bracket from being separated from the slide rail during the adjustment process.

[0014] Preferably, the stop block is made of polyurethane. By making the stop block of polyurethane, it can play a buffering role when the mounting frame collides with the stop block, thereby avoiding the reduction of the accuracy of the centering device caused by excessive impact force.

[0015] Preferably, the centering end includes a support plate and a centering block, and the centering block is detachably arranged on the support plate, and the centering block is used to abut against the sheet. By providing a detachable centering block, the centering block can be replaced separately after the centering device is worn out after long-term use, without the need to disassemble and replace the centering parts, thereby reducing the cost of equipment consumables and the maintenance time.

[0016] Preferably, the end face of one side of the centering block that contacts the material sheet is arranged in an arc shape. By arranging the end of the centering block that contacts the material sheet in an arc shape, the centering of the special-shaped material sheet can be achieved.

[0017] It can be seen from the above technical solutions that the advantages of the utility model are as follows: through the set centering piece and lifting mechanism, when the sheet needs to be abutted and centered, the lifting mechanism rises, so that the centering piece rotates with the hinge shaft as the axis, and the upper end of the centering piece moves in the Y-axis direction and the Z-axis direction, thereby realizing the rapid abutment and centering of the sheet, and improving the centering rate of the sheet in the Y-axis direction. Through the set cylinder, the rising and falling actions of the lifting mechanism can be completed quickly, that is, the centering action of the sheet can be realized quickly, and the centering rate of the sheet in the Y-axis direction can be further improved. Through the set bending plate and the first wear-resistant plate, the cylinder will swing with the action during the operation of the lifting mechanism. At this time, the set first wear-resistant plate can extend the wear time between the lifting mechanism and the mounting frame, and improve the service life of the equipment. Through the set guide rail and locking mechanism, during the centering process of sheets of different sizes, the clamping mechanism can be released, and then the position of the mounting frame can be appropriately adjusted to adapt to the centering action of the new size sheet. By means of the screw and the second locking block, when the clamping mechanism needs to be released or locked, it is only necessary to rotate the locking handle, and the locking handle drives the screw to rotate, and the screw makes the second locking block move away from or close to the first locking block to complete the release or locking of the clamping mechanism. By means of the provided scale and pointer, the size of the mounting seat adjustment can be calculated according to the length difference of the sheet in the Y-axis direction during the centering process for sheets of different sizes. At this time, the provided scale and pointer enable the staff to accurately complete the position change of the mounting frame by only adjusting once. By means of the provided limit block, the mounting frame will not be separated from the slide rail during the adjustment process. By making the limit block from polyurethane, it can play a buffering role when the mounting frame collides with the limit block, avoiding the reduction of the precision of the centering device caused by excessive impact force. By means of the provided detachable centering block, the centering block can be replaced separately after the centering device is worn out after long-term use, without the need to disassemble and replace the centering parts, thereby reducing the cost of equipment consumables and the maintenance time. By setting the end of the centering block abutting against the sheet to an arc, the centering of the special-shaped sheet can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS
