Abstract
The invention discloses a pipe cutting assembly for a pipe cutting machine, comprising a spindle, wherein a rotary knife rest is fixedly arranged on the end of a main shaft; one side of the rotary knife rest is provided with a feeding control pulley; the feeding control pulley is connected with the main shaft in a sliding and sheathing way; the rotary knife rest is a hollow circular plate body; two pipe cutting knives are symmetrically arranged on the rotary knife rest; a clearance is kept between the two pipe cutting knives; the pipe cutting knives are connected with a wedge-shaped block; the wedge-shaped block is arranged along the axial direction of the main shaft; a spring is arranged between the wedge-shaped block and the main shaft; the interior of the feeding control pulley is provided with a conical surface; and the feeding control pulley is inserted into the rotary knife rest, so that the conical surface cooperates with the wedge-shaped block in a contact way. The rotary knife rest rotates together with the main shaft; meanwhile, the feeding control pulley constantly penetrates into the rotary knife rest under the action of external force; under the pressure action of a conical cooperation face, the two pipe cutting knives are pulled to cut towards the excircle of a pipe; and the cutting is deeper and deeper till the pipe is cut off.
Description
Technical field
The present invention relates to a kind of pipe cutter that is used to cut pipe, particularly a kind of pipe cutting assembly that is used for pipe cutter.
Background technology
Riser is a vitals of forming in the diffusion absorption type refrigeration system, and riser must be reserved a segment length for the ease of the clamping of pipe and be used for clamping before bend pipe, and bend pipe must be removed redundance again after accomplishing; And the riser shape that bends is more special; Be difficult to cutting with common method, and pipe is injury-free in when cutting off outer tube, must guaranteeing, such cutting machine can not be used for cutting; Otherwise inner and outer pipes has been cut off together; Unique can use be with cutter slowly rotating of a circle circle cut, but the efficient all too is low like this, can not satisfy the needs of processing far away.
Just very be necessary with the pipe cutter of raising the efficiency so research and develop a kind of pipe cutting automatically, but in R&D process, each parts, link all need well-designed, all linked with one another to realize final purpose.
Summary of the invention
The present invention has overcome the deficiency that exists in the above-mentioned prior art, and a kind of cutting that is beneficial to is provided, the pipe cutting assembly of increasing work efficiency; This pipe cutting assembly is the important component part of pipe cutter; Directly contact and cut with pipe, specifically, the pipe cutter are around pipe one circle circle rotation; Thereby pipe is cut off, and interior pipe is intact when guaranteeing to cut off outer tube.
Technical scheme of the present invention is achieved in that
A kind of pipe cutting assembly that is used for pipe cutter comprises the main shaft of rotation being fixed with swivelling tool-holder in the end of main shaft; Swivelling tool-holder one side is provided with feed control pulley, feed control pulley and main shaft slip socket, and swivelling tool-holder is the hollow circular disk body; On swivelling tool-holder, be arranged with two pipe cutter, the pipe cutter are along the same diametric(al) setting of swivelling tool-holder, leave the gap between two pipe cutter; The pipe cutter are connected with wedge, and wedge is along the setting of main shaft axial direction, is provided with spring between wedge and the main shaft; Feed control pulley inside is provided with the conical surface, and feed control pulley inserts in the swivelling tool-holder and makes the conical surface and wedge contact matching.
As preferably, be provided with groove in the bottom of wedge, an end of spring is plugged in the groove, and the other end and the main shaft of spring offset.On the one hand can so that spring install, on the other hand can so that wedge, pipe cutter reset.
As preferably; Described pipe cutter comprise tool rest; Chute on described tool rest and the swivelling tool-holder is slidingly connected, and on tool rest, is provided with the cutter installing hole that runs through whole tool rest, in the cutter installing hole, cutting tool is set; On the tool rest sidewall, be provided with pinching screw, pinching screw and cutting tool offset.Adopted said structure, made cutting tool to regulate, the pipe of convenient processing different tube diameters.
Adopted the principle of the present invention and the beneficial effect of technique scheme to be:
Swivelling tool-holder of the present invention follows main shaft to rotate in the lump; The control of feed simultaneously pulley constantly gos deep into swivelling tool-holder under external force, because feed control pulley is taper with the face that the interior wedge of swivelling tool-holder contacts, the wedge in the swivelling tool-holder is connecting the pipe cutter again; So under the effect of pressure; Two pipe cutter are hauled on the cylindrical of pipe undercutting and are gone, and along with the slowly propelling of feed control pulley, double-pole cuts more more deeply on tube wall and cut off up to pipe.
Main shaft of the present invention can be by motor-driven, and feed control pulley can connect a handle, is passed by manual work.
