Abstract

The utility model provides a chemical processing tool for square pipes. The chemical processing tool comprises a frame body, a metal mesh and a plurality of supporting frames, wherein the frame body is composed of a plurality of transverse rods, a plurality of stand columns, a plurality of inclined rods, a plurality of connecting rods and a plurality of transverse beams to form a rectangular frame structure with an open upper side, the metal mesh is fixedly laid on the periphery of the inner side of the frame body, each supporting frame comprises a transverse rod and a plurality of positioning toothed bars, the positioning toothed bars are longitudinally arranged along the transverse rods at intervals, lower ends of the positioning toothed bars are vertically fixed on the transverse rods, the supporting frames are arranged at the two ends in the frame body in the longitudinal direction respectively, the two ends of the square pipes are supported between the positioning toothed bars of the supporting frames respectively, and the supporting frames for placing the square pipes are arranged in the frame body in an up-and-down multi-layer stacking mode. The chemical processing tool for the square pipes is simple in structure, can process multiple workpieces in bulk at one time, is convenient to operate, saves manpower and materials and improves production efficiency; the supporting frames are be repeatedly used, the utilization rate is high, cost is saved, and generation of secondary pollution does not occur.

Description

Square tube chemical treatment frock

Technical field

The utility model relates to a kind of chemical treatment frock of shape, especially a kind ofly can carry out the parkerized special tooling of batch to many square tubes, belongs to chemical treatment auxiliary device technical field.

Background technology

The bulkhead that forms hexahedron vehicle mounted square cabin cabin body first becomes framework by steel square tube assembly welding conventionally, then framework both sides respectively with the plate of being riveted into one of sheet steel, before square tube assembly welding, need to carry out coating processing, to improve its antiseptic property.In order to improve the coating adhesive ability of square tube, before applying, square tube need be by techniques such as alkali cleaning, pickling, phosphatization processing, in order to remove the impurity such as oil that steel square tube surface speckles with, rust, and at steel square tube surface formation phosphate coating, thereby improve its antiseptic power.Traditional method is with iron wire, many square tubes to be bundled into after rectangular structure to lifting to immerse in conditioning fluid and carry out alkali cleaning, pickling, phosphatization processing etc., this method production efficiency is low, be not easy to batch manufacturing, and many square tube sides are close together up and down, the alkali cleaning, pickling and the phosphatization that are unfavorable for square tube surface are processed, and iron wire consumption is large, has increased the processing cost of square tube, the iron wire immersing in chemical treatment pool has consumed chemical pretreatment solution more, causes secondary pollution.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, production efficiency is high, can carry out in batches parkerized workpiece phosphatization processes hanging box.

The utility model is achieved by the following technical programs:

A kind of square tube chemical treatment frock, comprise framework, metal gauze and a plurality of bracing frame, described framework is by several cross bars, several columns, several braces, many pipe links and several crossbeam are fixedly connected into the unlimited rectangular frame structure of upside, framework both lateral sides is arranged with several hangers, the longitudinal two ends of framework are respectively equipped with suspension bracket, described metal gauze is fixedly laid on surrounding inside framework, support frame as described above comprises cross bar and Duo Gen location ratch, described many location ratch arrange along cross bar longitudinal interval, ratch lower end, location is vertically fixed on cross bar, bracing frame is separately positioned on longitudinal two ends in framework, many square tube two ends are supported on respectively respectively locating between ratch of bracing frame, place upper and lower multilayer laminated being arranged in framework of a plurality of bracing frames of square tube.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid square tube chemical treatment frock, the location ratch height h of wherein said bracing frame is 0.5～0.7 times of square tube height L.

Aforesaid square tube chemical treatment frock, the cross bar of wherein said bracing frame and Duo Gen location ratch all adopt bar section of stainless steel to make.

The utility model is simple in structure, places upper and lower multilayer laminated being arranged in framework of a plurality of bracing frames of square tube, between square tube is upper and lower, by the ratch that is positioned between cross bar, left and right, is separated, and has improved the chemical treatment effect on square tube surface.Can many square tubes of batch processing, not only easy to operate, saved manpower and materials, improved production efficiency, and bracing frame can repeatedly reuse, need not consume tie wire, reduced use cost, non-secondary pollution phenomenon occurs.

Advantage and disadvantage of the present utility model, the non-limitative illustration by preferred embodiment below is for illustration and explanation, and these embodiment, only provide as an example with reference to accompanying drawing.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is the A-A cutaway view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing and the parkerized embodiment of square tube, the utility model is described in further detail.

As shown in FIG. 1 to 3, the utility model comprises framework 1, metal gauze 2 and 10 bracing frames 3, framework 1 is welded into the unlimited rectangular frame structure of upside by several cross bars 11, several column 12, several brace 13, many pipe links 14 and several crossbeam 15, cross bar 11, column 12, brace 13, pipe link 14 and crossbeam 15 all adopt square tube to make, framework 1 both lateral sides is arranged with 4 hangers 16, its longitudinal two ends are respectively equipped with suspension bracket 17, are convenient to lift by crane framework 1.Metal gauze 2 is fixedly laid on framework 1 inner side surrounding, can prevent square tube 4 framework 1 that comes off in lifting process.Bracing frame 3 comprises

cross bar

32 and 11 location ratch 31,11 location ratch 31 are along cross bar 32 longitudinal interval settings, also more location ratch 31 can be set as required, the height h of location ratch 31 is 0.5～0.7 times of square tube 4 height L, in the present embodiment, h is 0.6 times of L, thereby guarantees that ratch 31 height in location are lower than square tube 4 height.Be convenient to bracing frame 3 stacked on top of one another settings, ratch 31 lower ends, location are vertically welded on cross bar 32.Bracing frame 3 is separately positioned on the interior longitudinal two ends of framework 1, and many square tube 4 two ends are supported on respectively respectively locating between ratch 31 of bracing frame 3, and 10 bracing frames 3 placing square tube 4 are divided into 5 layers of stacked on top of one another and are arranged in framework 1.When phosphatization is processed, framework 1 lifting that many square tubes 4 are housed is immersed in etching solution, so once just can 50 or 50 above square tubes 4 of batch processing.

In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
