[0024] Referring to Figure 1 , the lamp tube support punching machine, including base frame, material supporting groove 100, limit support and punching driving element 310;Material supporting groove 100 is connected to the top side of the base frame;The limit support is connected to the top side of the base frame, the limit support top side is connected with the pressing plate 210, the pressing plate 210 is located above the material supporting groove 100, the limit support is used to provide connection support for the pressing plate 210, so that the pressing plate 210 is relatively fixed on the position above the material supporting groove 100, the pressing plate 210 and the material supporting groove 100 form a limit area, the first avoiding hole is arranged on the position close to the end part of the material supporting groove 100 of the pressing plate 210;Punching driving element 310 is arranged in the base frame, the punching driving element is driven to be connected with punching cutter 320, and the punching driving element 310 is mainly used to provide driving force reciprocating in the up-down direction, and its structure form has a plurality of kinds, for example, the punching driving element 310 can adopt air cylinder, screw rod or hydraulic cylinder etc. Among them, the punching driving element 310 drives the punching cutter 320 to move up and down, when the punching cutter 320 moves upwards, the punching cutter 320 passes through the end part of the material supporting groove 100 and inserts the first avoiding hole, when the punching cutter 320 moves downwards, the punching cutter 320 exits the limit area downwards.

[0025] From the above, the lamp holder to be cut is sent into the limiting area, the lamp holder is supported by the material supporting groove 100, the lamp holder is conveyed along the material supporting groove 100, when the lamp holder is conveyed to the position opposite to the punching cutter 320 according to the required length, the lamp holder is kept stationary relative to the base, the punching cutter 320 is driven by the punching driving part 310 in the punching mechanism to move upward, the punching cutter 320 passes through the end of the material supporting groove 100 upward and inserts into the first avoiding hole of the pressing plate 210, so as to realize the punching of the lamp holder. In this process, the pressing plate 210 can limit the upward movement of the lamp holder, ensure the stability of the position of the punching cutter 320 when punching the lamp holder, prevent the lamp holder from coming out of the material supporting groove 100, improve the punching quality of the lamp holder, and after completion, the punching driving part 310 drives the punching cutter 320 to exit the limiting area downward, the subsequent lamp holder to be cut continues to be conveyed, and the cut lamp holder is ejected from the material supporting groove 100. Thus, the lamp holder is punched from bottom to top by the punching cutter 320, which can realize the quick cutting of the lamp holder, reduce the requirement of the punching cutter 320 to have a sharp blade, reduce the wear of the punching cutter 320, prolong the service life of the punching cutter 320, and reduce the production and processing cost.

[0026] When the punching cutter 320 punches the lamp holder, the waste material will be brought out and will be raised upward along the punching cutter 320. In order to facilitate the collection of the waste material, a collecting box 410 is arranged on the base in the embodiment, the collecting box 410 is located on the top side of the pressing plate 210, a second avoiding hole is arranged on the position of the collecting box 410 opposite to the first avoiding hole, and the punching cutter 320 can move upward and insert into the second avoiding hole. When the punching cutter 320 punches the lamp holder upward, the waste material will pass through the first avoiding hole of the pressing plate 210 and the second avoiding hole on the bottom side of the collecting box 410 upward under the driving of the punching cutter 320, and then enter the collecting box 410. The waste material is collected by the collecting box 410, so as to effectively prevent the waste material from splashing around and facilitate the recycling of the waste material.

[0027] The waste is collected in the collecting box 410, and needs to be recycled regularly. Since the punching cutter 320 will be inserted into the collecting box 410 upward during work, the inside of the collecting box 410 needs to be cleaned after stopping. In order to reduce the cleaning frequency of the collecting box 410, a discharge chute 420 is connected to the bottom of one side of the collecting box 410 in the embodiment. The discharge chute 420 extends downward and away from the collecting box 410. The discharge chute 420 is a groove structure connected to the inside of the collecting box 410. When the waste is collected and accumulated in the collecting box 410, part of the waste will be discharged outward from the discharge chute 420. Only a container for recycling waste needs to be placed below the discharge chute 420 to collect the waste. In this way, the waste in the collecting box 410 can be prevented from accumulating too much, and the machine can be stopped for cleaning the inside of the collecting box 410.

[0028] The punching cutter 320 has a blade head to realize the slitting of the lamp holder. The blade head can be a horizontally extending structure.

The main blade head 321 extends upward and forms a punching tip on both sides of the width direction. The main blade head 321 forms a convex structure with high middle and low sides. When the lamp holder is punched, the punching tip at the top of the main blade head 321 increases the pressure when pressing against the lamp holder, which can better pierce the lamp holder and cut it transversely along the sides of the main blade head 321, further improving the smoothness and efficiency of the punching cutter 320 in punching the lamp holder.

[0029] Further, the punching cutter 320 forms a secondary blade head 322 on both sides of the main blade head 321 along the width direction. The top of the two secondary blade heads 322 is provided with a rounded corner. The two secondary blade heads 322 are located on both sides of the main blade head 321. When the bottom side of the lamp holder is contacted, the rounded corners of the two secondary blade heads 322 opposite to each other can better adapt to the width of the lamp holder, stabilize the position of the lamp holder, and cut off from both sides of the lamp holder as the punching cutter 320 moves upward. In this way, the cutting efficiency and quality of the punching cutter 320 on the lamp holder can be further improved.
