Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, specifically to a composite processing equipment for sheet metal sheet metal processing, which involves sheet metal stamping and flanging. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets (usually less than 6mm), including shearing, punching / cutting / compound cutting, bending, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. Due to their thinness, sheet metal sheets are also called flexible metal sheets. The processing of flexible metal sheets generally includes multiple processes such as stamping and flanging. Existing machine tools can complete multiple processes such as stamping and flanging in one go. These machine tools are also called composite machine tools. Because the mutual attraction force is large when flexible metal sheets are stacked, they often need to be separated and sorted. The most widely used sorting method in the current technology is magnetic reverse sorting equipment.

[0003] After being magnetically sorted, flexible metal sheets are typically fed using suction cups. However, the time required for the suction cups to travel back and forth is relatively long, which increases the overall processing time of the sheet. Therefore, this method does not meet the current requirements. To address this, we propose a sheet metal flexible processing equipment that combines sheet metal stamping and flanging. Summary of the Invention

[0004] The purpose of this invention is to provide a sheet metal flexible processing equipment for sheet metal stamping and flanging composite processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sheet metal flexible processing equipment for sheet metal stamping and flanging composite processing, comprising:

[0006] The magnetic sorting module includes multiple magnetic sorters that are movable and adjustable and connected to a power source. The magnetic sorters are used to magnetically sort stacked flexible metal sheets, so that adjacent flexible metal sheets are separated from each other.

[0007] The feeding auxiliary mechanism includes two symmetrically positioned and adjustable movable plates. The bottom of the movable plates is equipped with a rotatable auxiliary screw conveyor rod. The auxiliary screw conveyor rod is used to spirally convey the plates that have been magnetically sorted upwards, so as to realize the continuous separation and conveying of the plates.

[0008] Stamping and flanging machine tool, used for stamping and flanging processes on flexible metal sheets;

[0009] Roller conveyor, which includes a frame, a power structure and two rows of conveying rollers, uses the two rows of conveying rollers to convey a flexible metal plate lifted by an auxiliary spiral conveying rod toward a stamping and flanging machine.

[0010] The belt conveyor transports the flexible metal sheet, which has been moved and conveyed by the roller conveyor, into the stamping and flanging machine.

[0011] Preferably, the feeding auxiliary mechanism further includes two support frames symmetrically distributed and fixed to the magnetic sorting module, two guide support rods fixed between the two support frames, a movable plate slidably mounted on the outside of the guide support rods, and an auxiliary motor fixed on the top of the movable plate.

[0012] Preferably, the output shaft of the auxiliary motor extends through the top of the moving plate into the interior of the moving plate, the top end of the auxiliary spiral conveying rod extends through the bottom end of the moving plate into the interior of the moving plate, a drive sprocket is fixed to the outside of the output shaft of the auxiliary motor, a driven sprocket is fixed to the outside of the top end of the auxiliary spiral conveying rod, and a drive sprocket is provided on the outside of the driven sprocket and the chain.

[0013] Preferably, one end of the movable plate is fixed with a fixed frame, a laser positioner is fixed on the inner side of the bottom end of the fixed frame, and a positioning nameplate is embedded on the outer surface of the bottom end of the auxiliary spiral conveying rod near the fixed frame.

[0014] Preferably, an adjustable electric telescopic rod is fixed to the inner side of the support frame, the movable end of the adjustable electric telescopic rod is fixed to the moving plate, and a feeding electric telescopic rod is fixed to the surface of the two moving plates facing each other. A feeding plate is fixed to the piston rod end of the feeding electric telescopic rod, and the feeding plate is in an inclined state.

[0015] Preferably, the magnetic sorting module further includes a base, the surface of which is provided with a rectangular groove, a vertical hydraulic rod is fixed inside the rectangular groove, and a lifting plate is fixed on the top of the hydraulic rod.

[0016] Preferably, a vertical plate is fixed to the upper surface of the lifting plate, and a first longitudinal electric telescopic rod is fixed to the outer side of the vertical plate. The movable end of the first longitudinal electric telescopic rod is fixed to one of the magnetic separators.

[0017] Preferably, the surface of the base is further fixed with a second longitudinal electric telescopic rod and two transverse electric telescopic rods. The axis of the second longitudinal electric telescopic rod coincides with the axis of the first longitudinal electric telescopic rod, and the axes of the second longitudinal electric telescopic rod and the first longitudinal electric telescopic rod are perpendicular to the axis of the transverse electric telescopic rods.

[0018] Preferably, the remaining three magnetic separators are fixed to the movable ends of the second longitudinal electric telescopic rod and the two transverse electric telescopic rods, respectively. The second longitudinal electric telescopic rod and the first longitudinal electric telescopic rod are symmetrically positioned on the top projection plane of the base, and the two transverse electric telescopic rods are symmetrically positioned on the top projection plane of the base. Furthermore, the initial length of the movable end of the second longitudinal electric telescopic rod and the subsequent moving speed of the movable end are consistent when the first longitudinal electric telescopic rod is started, and the initial length of the movable end of the two transverse electric telescopic rods and the subsequent moving speed of the movable end are consistent when the two transverse electric telescopic rods are started.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention places the propeller blades at the bottom of the auxiliary spiral conveyor rod between two adjacent and suspended flexible metal sheets, and uses an auxiliary motor to drive the auxiliary spiral conveyor rod to rotate at a uniform speed in the same direction. This continuously lifts the flexible metal sheets after magnetic sorting, and the lifted flexible metal sheets are transferred to other positions by a roller conveyor and a belt conveyor. This achieves continuous and uninterrupted feeding, which saves a lot of time compared to traditional suction cup feeding, thereby improving the overall processing efficiency of flexible metal sheets.

[0021] 2. This invention uses a laser positioner to monitor the position of the positioning nameplate, thereby achieving the initial positioning of the auxiliary screw conveyor rod. This ensures that the initial positions of the auxiliary screw conveyor rods under the two moving plates are the same, and that all auxiliary screw conveyor rods move in a consistent manner under the drive of the two auxiliary motors with the same power and speed, thus preventing the lifted flexible metal plate from tilting.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] like Figure 1 As shown, the sheet metal flexible processing equipment for sheet metal stamping and flanging composite processing includes:

[0031] The magnetic sorting module 3 includes multiple magnetic sorters 304 whose positions are adjustable and connected to a power source. The magnetic sorters 304 are used to magnetically sort the stacked flexible metal sheets, so that the adjacent flexible metal sheets are separated from each other.

[0032] The feeding auxiliary mechanism 4 includes two symmetrically positioned and adjustable movable plates 404. The bottom of the movable plates 404 is provided with a rotatable auxiliary spiral conveying rod 406. The auxiliary spiral conveying rod 406 is used to spirally convey the plates that have been magnetically sorted upwards, so as to realize the continuous separation and conveying of the plates.

[0033] Stamping and flanging machine tool 1 is used to perform stamping and flanging processes on flexible metal sheets.

[0034] Roller conveyor 5 includes a frame, a power structure and two rows of conveying rollers. The rollers are used to convey the flexible metal plate, which has been lifted by the auxiliary spiral conveying rod 406, toward the stamping and flanging machine tool 1.

[0035] Belt conveyor 2 transports the flexible metal plate, which has been conveyed by roller conveyor 5, into the stamping and flanging machine tool 1.

[0036] like Figure 2 , Figures 4 to 6As shown, the feeding auxiliary mechanism 4 also includes two symmetrically distributed support frames 401 fixed to the magnetic sorting module 3. Two guide support rods 403 are fixed between the two support frames 401. The moving plate 404 is slidably installed on the outside of the guide support rods 403. An auxiliary motor 405 is fixed on the top of the moving plate 404. The output shaft of the auxiliary motor 405 extends through the top of the moving plate 404 and into the interior of the moving plate 404. The top end of the auxiliary screw conveyor 406 extends through the bottom end of the moving plate 404 and into the interior of the moving plate 404. A drive sprocket 409 is fixed on the outside of the output shaft of the auxiliary motor 405. A driven sprocket 410 is fixed on the outside of the top end of the auxiliary screw conveyor 406. The drive sprocket 409 is provided on the outside of the driven sprocket 410 and the chain 411.

[0037] The output of the auxiliary motor 405 is transmitted through the drive sprocket 409, driven sprocket 410 and chain 411, so that multiple auxiliary screw conveyor rods 406 rotate simultaneously and in the same direction, thereby achieving uniform and stable lifting motion of the flexible metal sheet.

[0038] A fixed frame 407 is fixed to one end of the movable plate 404. A laser positioner 408 is fixed to the inner side of the bottom end of the fixed frame 407. A positioning nameplate 414 is embedded on the outer surface of the bottom end of the auxiliary spiral conveying rod 406 near the fixed frame 407. The laser positioner 408 monitors the position of the positioning nameplate 414 to achieve the initial positioning of the auxiliary spiral conveying rod 406. This ensures that the initial positions of the auxiliary spiral conveying rods 406 under the two movable plates 404 are the same, and that the movements of all auxiliary spiral conveying rods 406 are consistent under the drive of the two auxiliary motors 405 with the same power and speed.

[0039] An adjustable electric telescopic rod 402 is fixed to the inner side of the support frame 401. The movable end of the adjustable electric telescopic rod 402 is fixed to the moving plate 404. Feeding electric telescopic rods 412 are fixed to the surfaces of the two moving plates 404 facing each other. A feeding plate 413 is fixed to the piston rod end of the feeding electric telescopic rod 412. The feeding plate 413 is in an inclined state. The feeding electric telescopic rod 412 controls the reciprocating movement of the feeding plate 413, pushing the flexible metal sheet raised to the highest point toward the roller conveyor 5. This allows the flexible metal sheet to be received by the roller conveyor 5 and transported to the belt conveyor 2, thereby changing the movement state of the flexible metal sheet.

[0040] like Figure 3As shown, the magnetic sorting module 3 also includes a base 301. The surface of the base 301 is provided with a rectangular groove. A vertical hydraulic rod is fixed inside the rectangular groove. A lifting plate 302 is fixed to the top of the hydraulic rod. A vertical plate is fixed to the upper surface of the lifting plate 302. A first longitudinal electric telescopic rod 303 is fixed to the outside of the vertical plate. The movable end of the first longitudinal electric telescopic rod 303 is fixed to one of the magnetic sorters 304. The hydraulic rod is used to control the lifting plate 302 and the object above the lifting plate 302 to lift and lower, so that the surface of the base 301 forms an unobstructed area, which facilitates the flexible metal sheet to be sent to the surface of the base 301 for subsequent magnetic sorting.

[0041] A second longitudinal electric telescopic rod 306 and two transverse electric telescopic rods 305 are also fixed to the surface of the base 301. The axis of the second longitudinal electric telescopic rod 306 coincides with the axis of the first longitudinal electric telescopic rod 303, and the axes of the second longitudinal electric telescopic rod 306 and the first longitudinal electric telescopic rod 303 are perpendicular to the axes of the transverse electric telescopic rods 305. The remaining three magnetic separators 304 are fixed to the movable ends of the second longitudinal electric telescopic rod 306 and the two transverse electric telescopic rods 305, respectively. The second longitudinal electric telescopic rod 306 and the first longitudinal electric telescopic rod 303 are projected onto the base 301 from a top view. The two transverse electric telescopic rods 305 are symmetrically positioned on the top projection plane of the base 301. The initial length of the moving end of the second longitudinal electric telescopic rod 306 and the subsequent moving speed of the moving end are consistent when the first longitudinal electric telescopic rod 303 is started. The initial length of the moving end of the two transverse electric telescopic rods 305 and the subsequent moving speed of the moving end are consistent when the two transverse electric telescopic rods 305 are started. The four magnetic separators 304 are moved by the transverse electric telescopic rods 305, the second longitudinal electric telescopic rod 306 and the first longitudinal electric telescopic rod 303, so as to achieve positioning of the flexible metal plate from four sides.

[0042] When the stacked flexible metal sheets are stamped and flanged, the power supply of the whole device is turned on and started. The lifting plate 302 is driven by the hydraulic rod to descend, so that the first longitudinal electric telescopic rod 303 and the magnetic separator 304 enter the base 301. Then the stacked flexible metal sheets are placed on the surface of the base 301 from the position of the first longitudinal electric telescopic rod 303 after descent. After placement, the first longitudinal electric telescopic rod 303 is reset.

[0043] At this time, the first longitudinal electric telescopic rod 303, the second longitudinal electric telescopic rod 306, and the transverse electric telescopic rod 305 are activated and drive the magnetic separator 304 to approach the side of the flexible metal sheet until the four magnetic separators 304 contact the four sides of the flexible metal sheet respectively. Power is supplied to the magnetic separators 304. After being powered on, the magnetic separators 304 cause the flexible metal sheet to have additional magnetic poles. At this time, the two adjacent flexible metal sheets are separated from each other under the repulsive influence of the additional magnetic poles, and one or more of the upper flexible metal sheets are in a suspended state.

[0044] At this point, the electric telescopic rod 402 is activated and drives the moving plate 404 to slide on the outside of the guide support rod 403, causing the auxiliary spiral conveying rod 406 at the bottom of the moving plate 404 to move closer to the side of the flexible metal plate until the bottom of the spiral blades at the bottom of the auxiliary spiral conveying rod 406 enters between the two uppermost flexible metal plates. At this time, the laser positioner 408 monitors the position of the positioning nameplate 414. If the positioning nameplate 414 is aligned with the laser positioner 408, the auxiliary motor 405 is started directly. If the positioning nameplate 414 is misaligned with the laser positioner 408, the auxiliary motor 405 needs to be started slowly and the auxiliary spiral conveying rod 406 needs to be rotated slowly until the position of the positioning nameplate 414 is aligned with the laser positioner 408, thus correcting the initial position of the auxiliary spiral conveying rod 406. This ensures that the subsequent actions of all auxiliary spiral conveying rods 406 are consistent and prevents the lifted flexible metal plate from tilting.

[0045] Next, the two auxiliary motors 405 start simultaneously with the same power and output speed. The auxiliary motors 405 drive the chain 411 to rotate through the driven sprocket 410. The chain 411 drives all the auxiliary screw conveyors 406 to rotate simultaneously through the driven sprocket 410. The auxiliary screw conveyors 406 located on the flexible metal plate rotate in the opposite direction and lift the suspended flexible metal plate upwards in a spiral until the flexible metal plate moves to the highest point.

[0046] After the flexible metal sheet reaches its highest point, the two electric telescopic feeding rods 412 are activated simultaneously, driving the feeding plate 413 to approach the flexible metal sheet. The feeding plate 413 pushes the flexible metal sheet between the upper and lower rows of conveying pipes of the roller conveyor 5, so that the roller conveyor 5 transfers the raised flexible metal sheet to the surface of the belt conveyor 2. Finally, the belt conveyor 2 sends the transferred flexible metal sheet into the stamping and flanging machine 1. The stamping and flanging machine 1 performs stamping and flanging processes on the fed flexible metal sheet, shortening the feeding time of the flexible metal sheet and thus improving the overall processing efficiency of the flexible metal sheet.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
