Abstract
The invention discloses a pipeline punching process. The pipeline punching process is characterized by clamping a pipeline, and a punch head is adopted to punch the side surface of the pipeline. According to the embodiment of the invention, the process comprises the following specific steps that A, the pipeline is placed in a clamping groove of a lower clamping block; B, an upper clamping block and the lower clamping block are closed together to clamp the pipeline; C, the punch head is controlled to enter from a punching positioning hole in the lower clamping block to punch the side surface of the pipeline. The invention discloses a completely new punching process. The punching process has the advantages that the working efficiency is improved, energy sources are saved, and environment is protected. Compared with the prior art, the punching process has outstanding substantive features and obvious advancement.
Description
Technical field
The present invention relates to the technical field of pipeline punching, specifically a kind of pipeline drilling technology and clamping device thereof.
Background technology
Present air conditioning for automobiles industry is faced with new technological innovation.What current pipeline punching adopted is mostly the form of holing, and this technique has many drawbacks.Easily there are a large amount of aluminium bits to splash during boring, have harmful effect to working environment.The aluminium bits splashed also are easy to enter pipeline and are adsorbed on tube wall inner chamber, and boring burr is very large, also needs after piercing to carry out manual cleaning or Ultrasonic Cleaning to pipeline, causes unnecessary waste.Beating during boring is comparatively large, has larger impact to the uniformity of product.
Therefore still need to be further improved existing technology, make production more be tending towards reasonable, effectively cut down finished cost, enhance product performance.
Summary of the invention
The object of the present invention is to provide a kind of new pipeline drilling technology, adopt the mode of punching to instead of conventional borehole, the various problems that bore process causes can be solved, overcome the shortcoming and defect existed in prior art.
To achieve these goals, technical scheme of the present invention is: a kind of pipeline drilling technology, it is characterized in that clamping pipeline, adopts drift punching in the side of pipeline.
According to a particular embodiment of the invention, the concrete steps of this technique are: A, be placed on by pipeline in the clamping slot of lower clamp; B, upper clamping block and lower clamp to be closed up, make it to clamp pipeline; C, control drift enter from the punching locating hole of lower clamp, carry out punching to the side of pipeline.
Another object of the present invention is to provide a kind of pipeline punching clamping device, adopt this gripping means grips pipeline, from the side punching, the various problems that bore process causes can be solved.
To achieve these goals, technical scheme of the present invention is: a kind of pipeline punching clamping device, comprise upper clamping block and lower clamp, upper and lower clamp is provided with corresponding clamping slot, the clamping slot that described upper and lower clamp is corresponding forms a holes for clamping after closing up, and it is characterized in that the side of described lower clamp is provided with a punching locating hole.
The invention discloses a kind of brand-new drilling technology, its advantage be to increase work efficiency, the effect of economize energy, protection of the environment, there is outstanding substantive distinguishing features and marked improvement compared to existing technologies.
Accompanying drawing explanation
Fig. 1 is punching technology structural representation of the present invention.
Fig. 2 is punching position schematic diagram of the present invention.
detailed description of the invention
With reference to the accompanying drawings, the present invention is described further.
As shown in Figure 1, pipeline 4 clamps by upper clamping block 1 and lower clamp 2, and pipeline 4 is positioned at clamping slot corresponding to upper and lower clamp, and drift 3 is under pressure by side punching on pipeline.Punching position such as dotted line in Fig. 2, Fig. 2 is punching position, and this position will calculate according to the size of pipeline diameter and required pore size and obtain, and on demand, changes the drift of different-diameter, can go out the hole varied in size on pipeline.After punching completes, use plug shaping, diameter of mandrel is the diameter (words that horseback riding type connects are without the need to shaping) of required punching.
Therefore, the pipeline punching clamping device that the present invention adopts, comprise upper clamping block 1 and lower clamp 2, upper and lower clamp is provided with corresponding semicircle clamping slot, the clamping slot that described upper and lower clamp is corresponding forms a holes for clamping after closing up, to clamp pipeline, it is characterized in that the side of described lower clamp 2 is provided with a punching locating hole 5.The radius of holes for clamping is R, and the radius of required punching is r, then the center line of punching is positioned at the position of the below R of lower clamp holes for clamping center line, and the radius of drift is
, the radius of punching locating hole should be advisable slightly larger than the radius 0.5-1mm of drift.
The present invention changes bit bore into drift punching, side blow is changed into by straight boring, the waste material that drift punching occurs is sheet, without the situation that aluminium bits during boring splash, substantially improve working environment, cylinder pressure enough makes punching one-step moulding, pipeline not very large beating, the uniformity of product obtains guarantee, decreases the generation of waste product.And smooth cut impulse-free robustness, decrease the technological process of deburring and cleaning, facilitate operating efficiency.Upper and lower clamp is determined according to pipeline to be processed, and the diameter of its clamping slot reduces 0.2mm-0.3mm slightly than pipeline diameter.Can not be excessive otherwise clamp can be caused not clamping, can not be too small otherwise that folder can be caused to print is dark.
