At the top of patrix, also control button is set, below four angles of patrix, all connects protection spring.The patrix that arranges of button moves downward and only needs button press to realize, simply easy to operate.And spring is arranged on below four angles, patrix can only be moved up and down, control also accurately convenient.

Described die is also arranged and is used for spacing spacing collar.The setting of this spacing collar can limit the amplitude that die opens, and sends to carry out cutting operation to facilitate the materials in the tube of different size.

The point of a knife of described thin slice cutting knife is set to wedge, and on thin slice cutting knife, the opposite end of point of a knife is shaped form.Carry out chip in the process of cutting to make every effort to outwards form to reduce indentation at cutting knife, cutting knife should have enough intensity, is easy to grinding.And when starting Pipe Cutting, cutting is inwardly formed, now die does not play shear action, and pipe indentation also just produces at this moment, therefore should shorten this process as far as possible, and that is done by cutting knife curve is elongated, to reduce the indentation phenomenon of pipe further.

The width range of the point of a knife of thin slice cutting knife is between 2mm-2.5mm.This scope is optimum range, can reduce the indentation phenomenon of materials in the tube to greatest extent.

The point of a knife subtended angle scope of thin slice cutting knife is between 30 °-40 °.This scope is optimum range, can reduce the indentation phenomenon of materials in the tube to greatest extent.

Compared with prior art, the beneficial effects of the utility model are:

1, in this programme, the motion of patrix is realized by the drive of motor, and spring is set between upper die and lower die, and spring has a maximum compression distance, so just define the ultimate range that patrix is descending, avoid the excessive materials in the tube of damaging needs cutting by pressure of patrix Bottom Runby under the control of motor, ensure the safety of operation; In this process, returning of patrix is realized by the flexible of spring, and be all by manually realizing moving upward of patrix with whole process in the past, operate more convenient and simple, efficiency is higher.
