Description

Technical Field

[0001] This application relates to the field of sheet metal processing, and particularly to a continuous bending device for sheet metal processing. Background Art

[0002] Sheet metal processing refers to a series of processing techniques using sheet metal materials (such as steel plates, aluminum plates, etc.) to manufacture various metal parts or products. Sheet metal processing mainly involves processes such as cutting, forming, and connecting metal sheets. Bending is one of the sheet metal processing methods, using a bending machine to bend metal sheets to form the required angles and shapes.

[0003] When the bending equipment performs continuous bending on multiple sheet metal parts, it is necessary to adjust each sheet metal part to the bending position of the bending equipment one by one. When the number of sheet metal parts to be processed is large, repeatedly adjusting the position of the sheet metal parts is time-consuming and laborious, increasing the labor intensity during operation by people. Moreover, there may be a certain positional deviation when people adjust the position of the sheet metal parts, thereby affecting the overall processing efficiency of the sheet metal parts.

[0004] Regarding the above related technologies, the inventor believes that there are defects in the inconvenient equal-spacing feeding of multiple sheet metal parts during continuous bending. Therefore, a continuous bending device for sheet metal processing is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the problem of inconvenient equal-spacing feeding of multiple sheet metal parts during continuous bending, this application provides a continuous bending device for sheet metal processing.

[0006] A continuous bending device for sheet metal processing provided by this application adopts the following technical solutions:

[0007] A continuous bending device for sheet metal processing includes a bending equipment. A conveyor belt is movably installed inside the bending equipment. One end of the conveyor belt drives a rotating shaft to extend outside the bending equipment and is installed with a stepping motor. A fixed frame is fixedly installed on the upper surface of the bending equipment. One side of the top end of the fixed frame is installed with an electric telescopic rod. One side output end of the electric telescopic rod is installed with a connecting piece. The upper surface of the fixed frame is symmetrically and throughly provided with sliding grooves. The bottom end of the connecting piece passes through the sliding grooves and is fixedly installed with a fixing plate. The bottom end of the fixing plate is symmetrically welded with limiting plates. One side of the outer surface of the fixed frame is fixedly installed with a support plate. Guide rods are obliquely and symmetrically movably installed inside the support plate. A support roller is rotatably installed on the upper surface of the guide rods. The bottom end of the guide rods is placed below the support plate and welded with a fixed dial. A bending mechanism is further provided on one side of the bending equipment for processing the sheet metal parts conveyed on the conveyor belt.

[0008] Preferably, the bending mechanism includes a bending table, which is fixedly installed at the edge near the conveyor belt inside the bending equipment. A hydraulic cylinder is arranged above the bending table on the upper surface of the bending equipment, and a bending head is installed at the output end of the lower bottom surface of the hydraulic cylinder.

[0009] Preferably, the bottom end of the limiting plate is of an inclined surface structure, and the inclined surfaces at the bottom ends of the two limiting plates are symmetrically arranged left and right.

[0010] Preferably, a support seat is fixedly installed on the upper surface of the guide rod, the support roller is rotatably installed inside the support seat, and the outer surface of the support roller is mutually attached to the inclined surface of the lower bottom surface of the limiting plate.

[0011] Preferably, spline holes are obliquely symmetrically formed on the upper surface of the support plate. A spline shaft is arranged in the middle on one side of the outer surface of the guide rod. The spline shaft on one side of the outer surface of the guide rod is located inside the spline hole, and the guide rod and the spline hole are mutually engaged.

[0012] Preferably, a first magnetic block is fixedly installed near the support seat at the top end of the guide rod, and a second magnetic block is fixedly installed at the opening of the spline hole on the upper surface of the support plate. The first magnetic block and the second magnetic block repel each other.

[0013] In summary, the present application includes the following beneficial technical effects:

[0014] By placing the sheet metal part on the upper surface of the conveyor belt and transporting it to the bending table, the connecting piece moves along the sliding groove to drive the limiting plate to move, so that the inclined surface at the bottom end of the limiting plate drives the guide rod to slide relatively up and down inside the support plate. The downward-moving fixed dial blocks the sheet metal part transported on the conveyor belt, and the upward-moving fixed dial cancels the limit of the sheet metal part and transports it to the lower part of the bending head for bending processing. Compared with the prior art, this solution has the effect of facilitating the continuous transportation and bending of multiple sheet metal parts at a certain interval, improving the interval adjustment effect during the continuous bending processing of multiple sheet metal parts, solving the problem that it is time-consuming and laborious for people to adjust the placement position of the sheet metal parts, and improving the continuous bending processing efficiency of multiple sheet metal parts.

Detailed implementation manners

[0019] The following further describes the present application in detail in conjunction with the attached Figures 1-3 drawings.

[0020] The embodiment of the present application discloses a continuous bending device for sheet metal processing. Refer to Figures 1-3 FIG. 1, a continuous bending device for sheet metal processing, includes a bending equipment 1. A conveyor belt 2 is movably installed inside the bending equipment 1. One end of the driving rotating shaft of the conveyor belt 2 extends outside the bending equipment 1 and is installed with a stepping motor 16. A fixing frame 6 is fixedly installed on the upper surface of the bending equipment 1. One side of the top end of the fixing frame 6 is installed with an electric telescopic rod 7. The output end on one side of the electric telescopic rod 7 is installed with a connecting piece 8. Symmetrically penetrating sliding grooves 9 are opened on the upper surface of the fixing frame 6. The bottom end of the connecting piece 8 passes through the sliding groove 9 and is fixedly installed with a fixing plate 10. The bottom end of the fixing plate 10 is symmetrically welded with limiting plates 11. The bottom end of the limiting plates 11 is of an inclined surface structure. The inclined surfaces at the bottom ends of the two limiting plates 11 are symmetrically arranged left and right. One side of the outer surface of the fixing frame 6 is fixedly installed with a supporting plate 12. Guiding rods 13 are symmetrically and obliquely movably installed inside the supporting plate 12. Supporting rollers 14 are rotatably installed on the upper surface of the guiding rods 13. The bottom ends of the guiding rods 13 are placed below the supporting plate 12 and welded with fixing shifting plates 15. A bending mechanism is further provided on one side of the bending equipment 1 for processing the sheet metal parts conveyed on the conveyor belt 2.

[0021] By placing multiple sheet metal parts on the upper surface of the conveyor belt 2 for transportation, the stepping motor 16 controls the conveyor belt 2 to perform stepping movements at a certain distance. The electric telescopic rod 7 is started to drive the connecting piece 8, the fixing plate 10 and the limiting plate 11 to move along the sliding groove 9. During the movement, the limiting plate 11 pushes the supporting roller 14 to move along the inclined surface at the bottom end of the limiting plate 11, the guide rod 13 slides up and down inside the supporting plate 12, while one fixed dial 15 slides down, the other fixed dial 15 rises. The single fixed dial 15 near the left side moves downward to block the sheet metal parts transported on the conveyor belt 2, and the fixed dial 15 near the right side is placed above the sheet metal parts. When the connecting piece 8 drives the limiting plate 11 to move in the reverse direction, the limiting plate 11 drives the fixed dial 15 on the right side to move downward, and the fixed dial 15 on the left side moves upward to reset. The fixed dial 15 on the right side moves and is inserted between two adjacent sheet metal parts, and the two fixed dials 15 cooperate with each other to cancel the limiting effect on a single sheet metal part, so that the single sheet metal part is transported at a certain interval along the upper surface of the conveyor belt 2, reflecting the positioning and adjustment effect of the fixed dial 15 on the sheet metal parts.

[0022] Refer to Figure 1 and Figure 2 , the bending mechanism includes a bending table 3, and the bending table 3 is fixedly installed at the edge near one side of the conveyor belt 2 inside the bending device 1. A hydraulic cylinder 4 is arranged above the upper surface of the bending device 1 near the bending table 3, and a bending head 5 is installed at the output end of the lower bottom surface of the hydraulic cylinder 4.

[0023] By transporting a single sheet metal part to the upper surface of the bending table 3 for bending processing, and starting the hydraulic cylinder 4 to drive the bending head 5 to move up and down, the bending head 5 presses down on the sheet metal part at the top of the bending table 3 and performs bending processing on the sheet metal part, reflecting the continuous bending processing effect of the bending head 5 on multiple sheet metal parts.

[0024] Refer to Figure 2 and Figure 3 , a support seat is fixedly installed on the upper surface of the guide rod 13, the support roller 14 is rotatably installed inside the support seat, the outer surface of the support roller 14 is mutually attached to the inclined surface of the lower bottom surface of the limiting plate 11. Spline holes are symmetrically and obliquely opened on the upper surface of the support plate 12. A spline shaft is arranged in the middle on one side of the outer surface of the guide rod 13, and the spline shaft on one side of the outer surface of the guide rod 13 is located inside the spline hole. The guide rod 13 and the spline hole are mutually engaged. A first magnetic block 17 is fixedly installed near the support seat at the top of the guide rod 13, and a second magnetic block 18 is fixedly installed at the opening of the spline hole on the upper surface of the support plate 12. The first magnetic block 17 and the second magnetic block 18 repel each other.

[0025] By rotating the support roller 14 inside the support seat, the support roller 14 is stably moved along the bottom end of the limit plate 11, so that the vertically moving guide rod 13 pushes the spline shaft to move inside the spline hole, thereby keeping the guide rod 13 in a stable lifting effect. When the limit plate 11 pushes the guide rod 13 to move downward, the first magnetic block 17 and the second magnetic block 18 approach each other. When the limit plate 11 cancels the limit on the guide rod 13, the guide rod 13 moves upward under the mutual repulsion of the first magnetic block 17 and the second magnetic block 18, reflecting the effect of the first magnetic block 17 and the second magnetic block 18 controlling the reset movement of the guide rod 13.

[0026] The implementation principle of a continuous bending device for sheet metal processing in an embodiment of the present application is as follows: By placing multiple sheet metal parts on the upper surface of the conveyor belt 2 for conveying, starting the electric telescopic rod 7 drives the connecting piece 8 to move along the sliding groove 9, so that the connecting piece 8 drives the fixed plate 10 and the limit plate 11 to move. The inclined surface at the bottom end of the limit plate 11 in the movement abuts against the outer surface of the support roller 14, thereby pushing the support roller 14 to move along the inclined surface at the bottom end of the limit plate 11, so that the guide rod 13 slides up and down inside the support plate 12, keeping the two fixed dial plates 15 in a relative movement state, that is, while a single fixed dial plate 15 slides down, the other fixed dial plate 15 rises. The single fixed dial plate 15 close to the left side moves downward to block the sheet metal parts conveyed on the conveyor belt 2, and the fixed dial plate 15 close to the right side is placed above the sheet metal parts. When the connecting piece 8 drives the limit plate 11 to move in the reverse direction, the limit plate 11 drives the fixed dial plate 15 on the right side to move downward, and the fixed dial plate 15 on the left side moves upward to reset under the mutual repulsion of the first magnetic block 17 and the second magnetic block 18, so that the fixed dial plate 15 on the right side moves and is inserted between two adjacent sheet metal parts, and the two fixed dial plates 15 cooperate with each other to cancel the limiting effect on a single sheet metal part, and the single sheet metal part is conveyed to the upper surface of the bending table 3 for bending processing. Then start the hydraulic cylinder 4 to drive the bending head 5 to move up and down, so that the bending head 5 presses down on the sheet metal part at the top of the bending table 3 and bends the sheet metal part, so that the fixed dial plate 15 reciprocates up and down to convey multiple sheet metal parts at a fixed distance and continuously bend and process them; compared with the prior art, this solution has the effect of facilitating the continuous conveying and bending of multiple sheet metal parts at a certain interval, improving the interval adjustment effect during the continuous bending processing of multiple sheet metal parts, solving the problem that it is time-consuming and laborious for people to adjust the placement position of sheet metal parts, and improving the continuous bending processing efficiency of multiple sheet metal parts.
