DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a cutting machine for guardrail processing that is easy to position, comprising:

[0022] An L-shaped base 1, the bottom of which is fixedly connected with four support columns 2, which are distributed in a rectangular shape, so that the L-shaped base 1 can be stably supported;

[0023] Positioning and cutting assembly; the positioning and cutting assembly comprises a U-shaped plate 3 fixed on an L-shaped base 1, a first electric push rod 7 and a second electric push rod 9 are installed on the U-shaped plate 3, a pressing plate 8 is fixedly connected to the output end of the first electric push rod 7, a connecting column is fixed to the output end of the first electric push rod 7, the pressing plate 8 is connected to the connecting column by bolts, and the pressing plate 8 can be removed by removing the bolts, and the required pressing plate 8 can be replaced according to actual needs, so as to clamp and position the guardrail steel pipe more stably;

[0024] A support platform 4 opposite to the pressing plate 8 is fixed on the L-shaped base 1, and a V-shaped groove 5 is provided on the support platform 4. Specifically, the guardrail steel pipe is placed in the V-shaped groove 5, and the staff controls the first electric push rod 7 to drive the pressing plate 8 to move downward, so that the pressing plate 8 is against the upper end of the guardrail steel pipe, and the V-shaped groove 5 can be used to stably clamp the guardrail steel pipe, which can be suitable for clamping circular and polygonal steel pipes and steel pipes of various diameters, avoiding the disadvantage of manually driving the screw to achieve clamping and increasing the workload of the staff;

[0025] A cutter 12 is installed at the output end of the second electric push rod 9, and a mounting plate is fixedly connected to the output end of the second electric push rod 9. The cutter 12 is installed at the bottom of the mounting plate. The cutter 12 includes a motor fixed to the bottom of the mounting plate, and a cutting blade is fixed to the output end of the motor; a guide rod 10 is fixedly connected to the upper end of the mounting plate, and the guide rod 10 penetrates the U-shaped plate 3 and is slidably connected thereto. Since the cutter 12 has power when it moves downward for cutting, the guide rod 10 is provided to guide the cutter 12, so that the downward movement of the cutter 12 is more stable;

[0026] The L-shaped base 1 is provided with two chip grooves 6 located inside the U-shaped plate 3 and below the cutting machine 12. During cutting, waste chips are generated and splash outward. The splashed waste chips can be shielded by the U-shaped plate 3, so that the waste chips fall between the U-shaped plate 3 and the L-shaped base 1. Since the chip grooves 6 are provided, the chips fall through the chip grooves 6. A chip box can be provided below the L-shaped base 1 to collect the chips, thereby avoiding the inconvenience caused to the staff by the splashed chips.

[0027] In addition, since most guardrails require a fixed length, a measuring mechanism is also included. The measuring mechanism includes a third electric push rod 14 fixed on the L-shaped base 1. The output end of the third electric push rod 14 is fixedly connected to a moving plate 11 sliding on the L-shaped base 1. A plurality of springs 15 are fixedly connected to the moving plate 11. The other ends of the plurality of springs 15 are fixed to a measuring plate 13 sliding on the L-shaped base 1. The L-shaped base 1 is provided with scale lines that match the measuring plate 13. The movement of the moving plate 11 and the measuring plate 13 is controlled by the third electric push rod 14. The scale lines can be used to know whether the measuring plate 13 is aligned with the measuring plate 13. The distance between the support platform 4 is such that when the guardrail steel pipe is against the measuring plate 13, the length cut by the cutting machine 12 is the required length of the guardrail; since the cutting machine 12 cuts the steel pipe and squeezes it, the steel pipe squeezes the measuring plate 13, and the spring 15 is compressed, so that the steel pipe will not be stuck between the cutting machine 12 and the measuring plate 13, and when the cutting machine 12 moves up, the cut steel pipe falls down; in this way, each time the steel pipe is cut, it is only necessary to press the steel pipe against the measuring plate 13 to cut out steel pipes of equal length; by adjusting the distance between the measuring plate 13 and the support platform 4, steel pipes of different lengths can be cut out;

[0028] It also includes a blanking mechanism, which includes a blanking trough 16 set throughout the L-shaped base 1. An inclined plate 17 is fixed on the L-shaped base 1. The inclined plate 17 is located below the blanking trough 16. The cut steel pipes fall through the blanking trough 16 and fall onto the inclined plate 17. The inclined plate 17 can guide the steel pipes to gather for subsequent collection.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
