Description

pipe cutter

technical field

The utility model relates to a tool, in particular to a pipe cutting tool.

Background technique

Guardrails are mainly used for the protection and protection of equipment and facilities in factories, workshops, warehouses, parking lots, commercial areas, public places and other occasions. Guardrails are usually made of round steel pipes. Generally, the round steel pipes are arranged regularly and then used metal Frames or beams are used to fix them together. In the prior art, the shearing of round steel pipes basically relies on cutting machines, which consumes a lot of energy, produces a large amount of metal powder during processing, and causes low material utilization and serious environmental pollution.

Utility model content

In view of this, the purpose of this utility model is to provide a pipe shearing tool with low energy consumption, no material loss during processing, high material utilization rate, and no pollution to the surrounding environment.

The pipe cutting tool of the utility model comprises a base, a fixed knife, a movable knife and a handle; the fixed knife is fixed on the base, and the movable knife is hinged to the fixed knife; the handle is fixed on the movable knife to drive the movable knife to rotate;

Further, it also includes a spacer, the spacer is arranged under the cutting edge of the fixed knife and fixed on the base;

Further, it also includes a pad iron, and the fixed knife is fixedly connected to the base through the pad iron;

Further, the cutting edges of the fixed knife and the movable knife are both inner arc cutting edges.

The beneficial effects of the utility model are: the pipe cutting tool of the utility model has low energy consumption, no material loss in the processing process, high material utilization rate, and no pollution to the surrounding environment.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

Fig. 1 is a schematic structural view of the utility model, as shown in the figure: the pipe cutting tool of the present embodiment includes a base 1, a fixed knife 2, a movable knife 3 and a handle 4; the fixed knife 2 is fixed on the base 1, and the The movable knife 3 is hinged to the fixed knife 2; the handle 4 is fixed to the movable knife 3 to drive the movable knife 3 to rotate, and the handle 4 realizes the force, so that the cutting process is labor-saving, the manual operation realizes the cutting, the cost is low, and the processing process is convenient. Material loss, high material utilization rate, no pollution to the surrounding environment.

In the present embodiment, a spacer 5 is also included, and the spacer 5 is arranged below the cutting edge of the fixed knife 2 and fixed on the base 1; the spacer 5 is used to support the pipe fittings, so as to avoid the pipe fittings from being deflected during processing, To ensure that the cut is neat, the pad 5 includes a pedestal and a support block, the support block is provided with a V-shaped groove for supporting the pipe, the support tube is vertically slidably connected to the pedestal, and the bottom surface of the support block is an inclined plane , There is a wedge between the support block and the seat, the wedge can slide horizontally, the wedge and the bottom surface of the support block are matched by a slope, and an adjustment bolt for driving the wedge to slide is provided between the wedge and the seat, and the adjustment bolt passes through The threaded connection is connected to the base, and the adjustment bolt is connected to the wedge by a single-degree-of-freedom rotation around its own axis. The rotation of the adjustment bolt can drive the wedge to slide, and then push the support block up and down through the inclined surface, which can adapt to the support and positioning of pipes of different thickness.

In this embodiment, a parallel iron 6 is also included, and the fixed knife 2 is fixedly connected to the base 1 through the parallel iron 6. Each component has a simple structure and is easy to manufacture and assemble.

In this embodiment, the cutting edges of the fixed knife 2 and the movable knife 3 are both inner arc cutting edges, which can buckle the pipe fittings within a certain size range, and avoid radial movement of the pipe fittings due to unbalanced force during shearing. , to ensure the stability and safety of the processing process.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
