Description

A kind of capillary loop cuts material structure

Technical field

The utility model belongs to automation equipment field, is related to cutting technique, and specially a kind of capillary loop cuts material knot Structure.

Background technology

Capillary is made up of copper tube, 1 ~ 6m of length, and internal diameter is 0.5 ~ 2mm.Can by the multiple combination of length and caliber The refrigerant system requirement for making it meet different operating modes and different refrigerating capacitys, is commonly used in the small-sized freon of below 20kW Refrigerating plant.

Capillary crudy will directly affect unit refrigeration, in addition can normal safe operation, in a conventional manner Cutting capillary is to use diagonal cutting pliers, and the capillary oral area cut into using this cutting mode is irregular, deformation, wiredrawn edge, interior Footpath diminishes, and the changes in flow rate for causing capillary is big, uniformity is poor, influences the performance of product, ID distortion after shearing, and breach is not Rule, all burrs of the mouth of pipe are more, and cutting efficiency is low.

Utility model content

In view of the deficiency in the presence of above-mentioned prior art, the purpose of this utility model is to provide a kind of cut quality The fast capillary loop of high, cutting speed cuts material structure.

To reach above-mentioned purpose, the utility model will be achieved through the following technical solutions：

A kind of capillary loop cuts material structure, it is characterised in that：Including feeding mandrel and ring cutting for transmitting capillary Structure, the feeding mandrel is made up of mandrel seat, plane bearing and mandrel, and the mandrel passes through mandrel seat and plane bearing, institute Plane bearing is stated on mandrel seat, the ring cutting structure is made up of drive, ring cutting tool rest, circular cutter and grinding disc, institute Drive is stated installed in the front end of the plane bearing, the circular cutter and the grinding disc are oppositely arranged on core the tip of the axis, Fixedly mount and be connected on drive by ring cutting tool rest respectively.

The adjustment of ring cutting cutter position for convenience, preferably, being provided with top below the drive in inclined-plane Ring cutting pretension knife, top and the end in contact under drive of the ring cutting pretension knife, is set between the plane bearing and drive There is return spring.

The utility model has advantages below and beneficial effect compared to existing technology：

The utility model sets circular cutter by feeding core the tip of the axis, and is driven by drive, realizes capillary Automatic ring cutting sawing sheet, simple, convenient safety, operating efficiency is high；Synchronously polished by the grinding disc being oppositely arranged, shearing Quality is high, breach regular smooth, the periphery impulse- free robustness of the mouth of pipe.

Brief description of the drawings

Fig. 1 is the schematic diagram that a kind of capillary loop of the utility model cuts material structure.

Specific embodiment

The utility model is described in further detail with reference to embodiment and accompanying drawing, but implementation of the present utility model Mode not limited to this.

Embodiment is as shown in figure 1, a kind of capillary loop cuts material structure, it is characterised in that：Including for transmitting capillary 1 Feeding mandrel 2 and ring cutting structure 3, the feeding mandrel 2 is made up of mandrel seat 21, plane bearing 22 and mandrel 23, the core Axle 23 passes through mandrel seat 21 and plane bearing 22, the plane bearing 22 to be arranged on mandrel seat 21, and the ring cutting structure 3 is by passing Driving wheel 31, ring cutting tool rest 32, circular cutter 33 and grinding disc 34 are constituted, before the drive 31 is arranged on the plane bearing 22 End, the circular cutter 33 and the grinding disc 34 are oppositely arranged on the end of mandrel 23, fixed by ring cutting tool rest 32 pacify respectively Fill and be connected on drive 31.

, by the feeding of feeding mandrel 2, drive 31 is by connecting ex-ternal transmission motor for capillary 1（Not shown in figure）, from And drive circular cutter 33 to run at high speed, automatic ring cutting sawing sheet, simple, convenient peace are carried out to capillary 1 using circular cutter 33 Entirely, operating efficiency is high；By the synchronous polishing of the grinding disc 34 being oppositely arranged, shearing quality is high, breach regular smooth, the week of the mouth of pipe Side impulse- free robustness.

Preferably, the lower section of the drive 31 is provided with ring cutting pretension knife 4 of the top in inclined-plane, the ring cutting pretension The top of knife 4 and 31 times end in contact of drive, are provided with return spring 5 between the plane bearing 22 and drive 31.Pass through The position of regulation ring cutting pretension knife 4, can adjust circular cutter 33 and the polishing being connected to by ring cutting tool rest 32 on drive 31 The position of piece 34, realizes resetting by return spring 5.

It is to be understood that, above-described embodiment is only the utility model preferably implementation method, but does not receive above-mentioned implementation The limitation of example, it is any without departing from the change or replacement made under Spirit Essence of the present utility model and principle, it is regarded as equivalent Substitute mode, be included within protection domain of the present utility model.
