Abstract
The suspension hook dragging workpiece being provided with conveying axis, suspension bracket on refined crystalline strengthening intensifier, including transfer gantry and suspension bracket, transfer gantry is combined the invention provides a kind of communication tower single-pipe tower surface cold deformation to move along conveying axis；The impact throwing hammer axle that some circular work distributions are provided with the Pao Chui operating rooms for surrounding workpiece, Pao Chui operating rooms is provided with described workpiece motion s route.Design specialized special installation of the present invention, carry out shallow-layer delay cold deformation and be combined refined crystalline strengthening, take into account intensity to improve, do not influence elongation percentage and yield strength, simultaneously because the adhesive force of follow-up galvanizing can be improved after compound refined crystalline strengthening, so as to realize the purpose increased the service life；One-piece machine member intensity 5 10% can be improved, is increased the service life and anti-corrosion life 15 30%, comprehensive resources efficiency improves more than 20%.
Description
Technical field
The present invention relates to communication tower surface of semi-finished processing unit field, specifically a kind of communication tower single-pipe tower surface is cold to be become
Shape is combined refined crystalline strengthening intensifier.
Background technology
General communication tower is that steel plate or other steel sectional materials make, and is without specially treated after steel plate bending welding
Carry out galvanizing, the subsequent handling, normal more than 5mm thickness materials service life more than 30 years such as spray painting, although the country to steel plate,
Steel have similar techniques research, but generally use light and improve intensity and surface strength, damage pliability, elongation percentage and bend
Take intensity, it is impossible to which the two takes into account combination, be merely able to reach the intensity and the later normal anti-corrosion of galvanizing that steel have in itself
Life-span and service life.
The content of the invention
The present invention is combined fine grain to solve problem of the prior art there is provided a kind of communication tower single-pipe tower surface cold deformation
Strengthen intensifier, the side to tubular workpieces flat surface is mainly completed in the protective cover of the adjustable speed of service and throwing hammer rotating speed
To dislocation impact so that surface of steel plate produces delayed deformation and crystal grain refinement so that adhesive force is greatly enhanced so that anti-corrosion
Service life is improved.
The present invention includes the suspension hook dragging workpiece being provided with transfer gantry and suspension bracket, transfer gantry on conveying axis, suspension bracket
Moved along conveying axis；The Pao Chui operating rooms for surrounding workpiece are provided with described workpiece motion s route, hammer work indoor location is thrown
Hammer axle is thrown in the impact for having some circular work distributions.
Further improve, described some impacts are thrown six, hammer axle and are equally spaced for one group along Workpiece periphery.
Further improve, described suspension bracket is connected by vibration generating apparatus with suspension hook, and workpiece is made during workpiece transport
Vibration, improves the throwing hammer effect that hammer axle is thrown in impact.
Beneficial effect of the present invention is：
Design specialized special installation, carries out shallow-layer delay cold deformation and is combined refined crystalline strengthening, take into account intensity and improve, do not influence elongation percentage
And yield strength, simultaneously because the adhesive force of follow-up galvanizing can be improved after compound refined crystalline strengthening, so as to realize that extension makes
With the purpose in life-span；One-piece machine member intensity 5-10% can be improved, is increased the service life and anti-corrosion life 15-30%, comprehensive resources
Efficiency improves more than 20%.
Brief description of the drawings
Fig. 1 is front view of the present invention.
Fig. 2 is side view of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Front view of the present invention as shown in figure 1, including transfer gantry 1 and suspension bracket 6, conveying axis 4 are provided with transfer gantry 1,
Suspension hook dragging workpiece 3 on suspension bracket 6 is moved along conveying axis 4；The throwing for surrounding workpiece 3 is provided with the described moving line of workpiece 3
Hammer into shape and the impact throwing hammer axle 2 that some circular work 3 are distributed is installed in operating room 7, Pao Chui operating rooms 7.
Side view of the present invention is as shown in Fig. 2 it is one group equidistant along the periphery of workpiece 3 that 2 six, hammer axle is thrown in described some impacts
Distribution.
Described suspension bracket 6 is connected by vibration generating apparatus 5 with suspension hook, and workpiece 3 vibrates workpiece when transporting, and is improved
The throwing hammer effect of hammer axle 2 is thrown in impact.
Operation principle of the present invention is：It is main to be completed in the protective cover of the adjustable speed of service and throwing hammer rotating speed to tubular workpieces
The lateral dislocation impact of flat surface so that surface of steel plate produces delayed deformation and crystal grain refinement, reaches what surface strength was improved
Effect, while only steel plate or workpiece surface intensity hardness increase, elongation percentage, pliability, the yield strength of steel plate in itself etc. does not have
Have an impact, pickling, galvanizing processing lifting effect after delayed deformation and crystal grain refinement for the later stage so that adhesive force increases
By force so that anti-corrosion service life is improved.
Concrete application approach of the present invention is a lot, and described above is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, under the premise without departing from the principles of the invention, some improvement can also be made, this
A little improve also should be regarded as protection scope of the present invention.
