TECHNICAL FIELD

[0001] The utility model relates to a stamping equipment especially a lamp tube support forming line. BACKGROUND

[0002] When lamp tube supports are formed, the lamp tube supports need to be punched to facilitate connection with lamp holder plugs during overall assembly. At present, before punching the lamp tube supports, a whole continuous lamp tube support needs to be cut into pieces according to the required length by a cutting knife, and then sent to a punching device for punching. Since this cutting method is low in efficiency and causes great wear of the cutting knife. After technical improvement, the lamp tube supports can be cut by a punching cutter, which is high in efficiency and causes less wear of the punching cutter. However, the end position of the lamp tube support is deformed during the punching process. If the lamp tube support is directly sent to the punching device for processing, the deformation will be intensified, affecting the lamp tube forming quality. Therefore, there is an urgent need for an equipment with better processing and forming effect. SUMMARY

[0025] Referring to Figure 1 With Figure 2The lamp holder forming line comprises a conveying device, a feeding mechanism and a punching and shaping mechanism. The conveying device has a conveying surface extending in the front-rear direction. The feeding mechanism is located on the conveying upstream side of the conveying device. The feeding mechanism has a feeding frame 210 capable of moving downward to approach the conveying surface or moving upward to move away from the conveying surface. The punching and shaping mechanism comprises working units located on the left and right sides of the conveying device. The working unit comprises a first base 310, a first upper die 320 and a first lower die arranged in the first base 310. The first base 310 is movable in the direction of approaching or moving away from the conveying surface. Of course, the first base 310 is drivingly connected with a first translation drive. The first base 310 is driven by the first translation drive to move leftward or rightward. The first translation drive can have various structural forms, for example, a cylinder, an electric screw or a hydraulic cylinder. The side of the first upper die 320 opposite to the conveying surface is provided with a shaping die 321. The first lower die is provided with a shaping block 331 and a punching rod 332. The first upper die 320 and the first lower die can approach each other, so that the shaping block 331 abuts against the shaping die 321, and the punching rod 332 penetrates into the shaping block 331 and the shaping die 321 upward.

[0026] As known from the above, the lamp holder to be punched is sent to the conveying surface of the conveying device. The conveying surface moves to drive the lamp holder to the punching and shaping mechanism. At this time, the first bases 310 in the two working units on the left and right sides of the conveying surface approach the conveying surface respectively, so that the shaping dies 321 on the left and right sides of the lamp holder enter the two ends of the lamp holder respectively to position the lamp holder leftward and rightward. The first lower die approaches the first upper die 320, so that the shaping block 331 of the first lower die abuts against the lamp holder and presses the lamp holder toward the shaping die 321. The deformed part of the lamp holder due to punching is flattened. At the same time, the punching rod 332 in the first lower die also moves upward relative to the shaping block 331 and penetrates through the lamp holder to punch the lamp holder. Since the shaping block 331 presses the bottom side of the lamp holder against the bottom side of the shaping die 321, the phenomenon that the surface of the lamp holder is deformed due to pulling when the punching rod 332 punches the lamp holder is effectively prevented. The punching quality of the lamp holder is improved. After completion, the first upper die 320 and the first lower die are separated from each other, the punching rod 332 exits the shaping block 331 and the lamp holder, the first base 310 and the second base 610 move away from each other, so that the two ends of the lamp holder exit the shaping dies 321 respectively. At this time, the lamp holder falls on the conveying surface and is continuously conveyed to the next station by the conveying surface. In this way, when the lamp holder is punched, the end positions of the lamp holder can be flattened and shaped at the same time, and the pulling deformation of the positions near the punching in the punching process is reduced, so that the quality and efficiency of the punching of the lamp holder are improved.

[0042] Further, the feeding frame 210 is surrounded by a feeding groove facing upward. The lamp holder can be directly sent into the feeding groove from the previous station, and the feeding groove limits the lamp holder. When the feeding frame 210 moves downward to place the lamp holder on the conveying surface, the lamp holder is effectively prevented from falling, and the stability of feeding the lamp holder is improved.

[0043] In order to assist the lamp holder to be translated and sent to the feeding frame 210, in the embodiment, the utility model further includes a sending mechanism, the sending mechanism includes a sending translation drive 710 and a sending gripper 720, the sending translation drive 710 is drivingly connected with the sending gripper 720, the sending translation drive 710 can drive the sending gripper 720 to move left and right to approach or move away from the feeding frame 210, and the sending translation drive 710 is mainly used to provide driving force for reciprocating translation in a straight line direction, and its structure form is various, for example, the sending translation drive 710 can adopt a pneumatic cylinder, an electric screw or a hydraulic cylinder, and the sending gripper 720 is mainly used to realize clamping and releasing the lamp holder, and can adopt an electric gripper finger, a pneumatic gripper finger and the like. When the lamp holder is fed to the feeding frame 210, the sending translation drive 710 drives the sending gripper 720 to move synchronously with the lamp holder, the sending gripper 720 clamps the lamp holder, assists the lamp holder to be fed to the feeding frame 210, when the feeding frame 210 is fed to the position, the sending gripper 720 releases the lamp holder, and the sending translation drive 710 returns to the position away from the feeding frame 210, so that the lamp holder can be accurately sent to the feeding frame 210, and it is especially suitable for the case that the lamp holder is pushed into the feeding frame 210 by an external device.

[0044] The preferred embodiments of the utility model are specifically described above, but the present application is not limited to the described embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims of the present application.
