The cutter of formula cooling tube.
【Background technology】
Screw pipe heat exchanger is a kind of heat transmission equipment for the novel high-efficiency and energy-saving released in recent years, it is in design
The mentality of designing of traditional shell-and-tube heat exchanger is breached completely, and that it changes traditional heat exchangers structure is simple, bulky, shape
The characteristics of coarse, inefficiency is the renewal product of traditional heat exchangers.Screw pipe heat exchanger is by core and housing
Two parts form, and core is mainly made of cooling tube, and housing is made of cylinder and end socket etc..At present both at home and abroad to the outer of cooling tube
Surface carries out rib processing, forms it into screwed pipe, increases the contact area of two media in heat exchanger, improves heat exchange effect
Rate.But in existing screwed pipe manufacturing process, there are problems：(1) due to using a knife is rolled, rolling now
Rough, after heat exchanger is using a period of time, the dirt particles in fluid are easy to be attached to the table of spiral cooling tube
At face and dead angle, even screw thread is filled and led up sometimes, forms very big dirtiness resistance, has severely impacted the heat exchange effect of heat exchanger
Rate；(2) for the softer spiral cooling tube of material, such as brass, aluminum pipe etc., easily deformed in the operation of rolling, cause to roll
Depth is difficult to accurately control, poor product quality.In use, what second-rate spiral cooling tube was easily broken shows
As two media in heat exchanger being caused to mix, so as to cause larger economic loss.
【Utility model content】
In view of this, it is overcome the deficiencies in the prior art, the utility model provides a kind of making spiral squeezing type cooling tube
Cutter, by the improvement of cutter structure, improve the finish of product, avoid the generation at product external surfaces " dead angle ", from
And improve heat exchanger effectiveness；Guiding mechanism is set, base tube in the production process is avoided and deforms, improve machining accuracy
And product quality.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of cutter for making spiral squeezing type cooling tube, including T-shaped pedestal, the one side of the pedestal upper end is provided with three
Dog chuck, claw is equipped on the scroll chuck, and the upper end of the pedestal is additionally provided with knife rest, the knife rest and the three-jaw
Chuck is located at the same side of the pedestal, and one end of the knife rest is provided with knife bar, the central shaft of the knife bar and the three-jaw
For the centerline of chuck in same level, one end of the knife bar is connected with cutter head, the cutter head with the knife bar is concentric sets
It puts.The guiding and /V of the scroll chuck and the claw for base tube, avoid in the manufacturing process of product, base tube hair
Change shape, and then causes machining accuracy low, poor product quality.The cutter head is made for steel alloy material, and hardness is high, light
Cleanliness is good, for the extrusion forming of base tube so that product surface is smooth, without " dead angle ", avoids the attachment of dirt particles object, improves
Heat exchanger effectiveness.
Preferably, being provided with contact on the inside of the claw, the one side of the contact is provided with circular groove, described
Contact is made for brass material, and material is softer and wear-resisting.In use, the contact is mutually butted on base tube, it is described arc-shaped
Groove is used for the /V of base tube, and base tube is avoided to deform.
Further, the knife bar is threadingly attached to the knife rest, and the screw thread is fine thread, convenient for the knife
The adjusting of bar axial direction, to adapt to the requirement of the base tube of different-diameter size.
Further, one end of the cutter head is in arc-shaped, avoids base tube stress in extrusion process and concentrates and damage.
The beneficial effects of the utility model are：(1) by the improvement of cutter structure, the finish of product is improved, is avoided
The generation at product external surfaces " dead angles " reduces the attachment of dirt particles object in fluid, so as to improve heat exchanger effectiveness；(2)
By the setting of scroll chuck, claw and contact, avoid base tube in the production process and deform, improve machining accuracy
And product quality, service life is longer, ensures the continuous service of system.
