Description
Technical field
The present invention relates to a kind of shot-blast apparatus, particularly a kind of section bar pre-treatment vertical shot-blasting device.
Background technology
Traditional section bar pre-processing shot-blast apparatus is the multi-part type material to be lain in to carry on the raceway side by side send into shot blast room, impeller head up and down in the shot blast room carries out Shot Blasting to each outer surface of section bar, finish rust cleaning and descaling, to increase the section bar outer surface roughness, improve the adhesive force of paint and to eliminate part stress to the section bar outer surface.
Fig. 1 is the front view of existing shot-blast apparatus, and Fig. 2 is the side view of existing shot-blast apparatus.
As depicted in figs. 1 and 2, this existing section bar pre-processing shot-blast apparatus comprises body 10, is arranged on the shot blast room 40 on the body 10 and carries section bar to pass the streamline 30 of shot blast room 40, be provided with 6 impeller head groups 20 in the shot blast room 40, each impeller head group 20 comprises two impeller heads 210,220.Under 18kw/ impeller head power condition, the linear velocity of streamline 30 is 11m/min, and the ball blast direction of impeller head 21 carries the direction (shown in the direction of arrow A among Fig. 1) of section bar to become 90 degree with streamline 30.In section bar Shot Blasting process, for each outer surface of guaranteeing section bar can both be fully and the effect of ball blast steel sand, must between section bar that keeps flat side by side and section bar, reserve certain clearance, but some position of section bar outer surface or dead angle area still have no marking sand or the not enough situation of sanding, and layout reason owing to each impeller head, make left, the direction of shaking out of right impeller head has intersection mutually, exist steel sand to beat the phenomenon of steel sand, section bar ball blast quality is produced harmful effect, thereby cause Shot Blasting of poor quality, energy resource consumption is higher, and these troubles and inconvenience remain to be improved in fact.
Summary of the invention
Purpose of the present invention exactly will be by transforming existing section bar pre-processing shot-blast apparatus, change existing section bar ball blast technology, by the existing multi-part type material technology mode that carries out ball blast placed side by side is changed into the single placement of section bar, the continuously uninterrupted technology mode that carries out ball blast of carrying is with the quality that realizes improving Shot Blasting, cut down the consumption of energy, reduce the device fabrication cost.
For achieving the above object, the invention provides a kind of section bar pre-treatment vertical shot-blasting device, comprise body, be arranged on the described body and comprise the shot blast room of a plurality of impeller head groups and be used to carry section bar to pass the streamline of described shot blast room, described a plurality of impeller head group carries the direction of section bar to be provided with at interval according to the order of sequence along described streamline, and around shifting to install, the traffic direction of the ball blast direction of each described impeller head group and described streamline conveying section bar in the same way and be predetermined angular around the circumferential hoop of described streamline for each described impeller head group.
Compared with prior art, the present invention improved effectively the section bar pre-processing shot-blast quality, reduced device fabrication cost and energy resource consumption.Being specially adapted to carry out uninterrupted section bar ball blast technology of carrying continuously, is the section bar ball blast streamline of carrying at small size roomy length continuity specially and designing.
Description of drawings

Fig. 2 is the side view of existing shot-blast apparatus;
Fig. 3 is the front view of shot-blast apparatus of the present invention; And
The side view of Fig. 4 shot-blast apparatus of the present invention.
The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Fig. 3 is the front view of shot-blast apparatus of the present invention, and the side view of Fig. 4 shot-blast apparatus of the present invention has omitted some parts that have nothing to do with the present invention among the figure, as the drive division that is used to drive impeller head and streamline grades.
As shown in Figure 3 and Figure 4, the present invention comprises the section bar pre-processing shot-blast apparatus body 1, is arranged on the shot blast room 4 on the body 1 and carries section bar to pass the streamline 3 of shot blast room 4, be provided with 4 impeller head groups 2 in the shot blast room 4, each impeller head group 2 comprises two impeller heads 21,22.
4 impeller head groups 2 carry the direction of section bar to be provided with at interval according to the order of sequence along streamline 3, and per two impeller head groups 2 center on the circumferential hoop of streamline 3 around shifting to install, and the ball blast direction of each impeller head 21,22 and streamline 3 carry the direction (direction shown in the arrow B among Fig. 3) of section bar equidirectional (promptly, carry the direction of section bars along streamline 3), and the angle between the two has predetermined angle.Described predetermined angular can for 0 the degree to 90 the degree between arbitrarily angled, such as be 30 the degree, 45 the degree, 60 the degree or 75 the degree equal angles.
As shown in Figure 4, described circumferential hoop around streamline 3 is around shifting to install the side that is meant from shot-blast apparatus, each impeller head not on the same cross section of shot-blast apparatus, promptly be not over against, but the certain position that staggers each other.Preferably, each impeller head group 2 is spent around shifting to install, so that the impeller head 21,22 of every pair of impeller head group 2 evenly shifts to install around streamline 3 around the circumferential one-tenth 90 of streamline 3.
When carrying out Shot Blasting, because impeller head carries the direction of section bar to be provided with according to the order of sequence along streamline 3, and impeller head dislocation layout, therefore can be when section bar be by delivery on streamline 3, steel sand when making ball blast is more fully beaten on section bar, can not cause steel sand to beat the phenomenon of steel sand simultaneously.According to the breadth width of section bar, adopted four groups of impeller heads, eliminated the dead angle that ball blast may occur like this.Simultaneously, because four groups of dislocation ball blasts, so increased the effective length of actual sanding working face, like this can be under the same units power condition (18kw/ impeller head), make the linear velocity of streamline 3 rise to 24m/min by 11m/min, accelerated productivity ratio greatly, thereby reduced cost, so not only can effectively improve the Shot Blasting of section bar outer surface quality but also can energy savings consumption.
Simultaneously, owing to taked the circumferential hoop that many groups impeller head is provided with according to the order of sequence at interval and each impeller head group centers on streamline around shifting to install, the Shot Blasting in the time of can realizing uninterruptedly carrying section bar continuously.
The preferable feasible embodiment of the present invention; can not therefore promptly limit to interest field of the present invention; concerning being familiar with those of ordinary skill in the art; such as use technical scheme of the present invention and technical conceive to make other various corresponding changes and distortion, and all these changes and distortion all should belong in the protection domain of claim of the present invention.
