Abstract
The utility model discloses a thin-wall extruded part traction device, which is capable of evidently reducing positive pressure of products during production and traction, decreasing deformation degree of the products and increasing pass rate thereof. The thin-wall extruded part traction device comprises a main frame, a motor and two traction belts, the two traction belts are in vertical symmetry, corresponding recessed traction fixtures are fixed outside traction blocks of the traction belts, a recessed side of each recessed traction fixture faces outwards to form a traction side, the recessed traction fixtures of the two traction belts which are in vertical symmetry correspond to each other to form a hollow cavity, and the shape of the hollow cavity is identical with the shapes of the products.
Description
Technical field
The utility model relates to a kind of draw-gear, especially relates to a kind of thin-walled class and extrudes the part draw-gear, and (wall thickness≤2.0mm) cavity is extruded the part traction to be used for the thin-walled class.
Background technology
The extrusion molding spare goods that we produce are cellular base station acceptance and emission outer covers with antenna, and antenna is when design, and the distance between its inner oscillator and the outer cover directly has influence on the performance of antenna.
The wall thickness of antenna house is thick more, and it is many more that the signal of telecommunication is just decayed in passing through the process of antenna house, otherwise it is just few more that the signal of telecommunication is decayed, and the signal of telecommunication of antenna acceptance and emission is just strong more.Extruded product needs a constant tractive force consistent with extruding direction when producing, the wall thickness of antenna house is thin more, and is yielding more behind the pressurized.The cross sectional dimensions of antenna house is big more, and the tractive force that needs is just big more.Tractive force is big more, and the normal pressure that product receives is just big more, and the deflection of the big more product of normal pressure is just big more; Common extruding is retained as parallel up and down and is flat shape; Be difficult to guarantee in process of production should the product compressive deformation in regime of elastic deformation, guarantee to accomplish transport requirement stably again, height is about 200mm; The thin-walled class of width about 300mm extruded part, its height and width tolerance be generally ± 1mm about.Therefore, need a kind of thin-walled class of exploitation to extrude the draw-gear of part.
Summary of the invention
The utility model has solved that cavity extrudes that part receives bigger normal pressure in distraction procedure and the problems and shortcomings that make the product distortion; Provide a kind of thin-walled class to extrude the part draw-gear; It can reduce the normal pressure of product in the production distraction procedure significantly, reduces the deflection of product, the accepted product percentage of raising product.
The technical scheme of the utility model is following:
The thin-walled class of the utility model is extruded the part draw-gear; Include main body frame, motor and laterally zygomorphic two traction belts; Every pair of guiding piece on the wherein said up and down traction belt all is in opposite directions and concavity; The spill traction anchor clamps of laterally zygomorphic two traction belts form cavity structure in correspondence with each other, and spill traction anchor clamps concave surface also contacts with it towards the product upper and lower surfaces and forms pulling face.
The thin-walled class of the utility model is extruded the part draw-gear, and its further technical scheme is that to be provided with transverse width be 3mm on described each guiding piece surface, and the degree of depth is the shallow grooves of 2mm; The quantity of groove is preferably 5; Its effect is (1) to prevent the guiding piece stress deformation, because of stress deformation reduces guiding piece and extrudes the contact area of part, thereby reduces tractive force; (2) as at guiding piece and product surface product sawing or foreign material etc. being arranged, can play the effect of skidding of preventing.
The thin-walled class of the utility model is extruded the part draw-gear, and can also to be described spill traction anchor clamps extrude the part little 10-20mm of height in kind in the size of vertical height direction than traction to its further technical scheme.
The thin-walled class of the utility model is extruded the part draw-gear, and its further technical scheme can also be that this thin-walled class is extruded the part draw-gear and also is provided with the adjusting rod that can adjust the height distance of traction belt up and down, controls the thrust of guiding piece to extrusion molding spare.Described traction clamping adjusting rod is M24 * 1.5, is installed in each one of forward and backward the right and left of hauling machine, amounts to 4.Through the up-down adjustment adjusting screw(rod), guaranteeing the product steady production, under the constant situation of tractive force, the suffered normal pressure of product this moment is minimum, can not receive the influence of air pressure fluctuation to the traction normal pressure simultaneously.
The beneficial effect that the utility model produced:
It is simple in structure, easy to use that the thin-walled class of the utility model design is extruded the part draw-gear, can reduce the deflection of product in the production distraction procedure, the accepted product percentage of raising product significantly; Low cost of manufacture can reduce production costs simultaneously.

The specific embodiment
Embodiment
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5
The thin-walled class of the utility model is extruded the part draw-gear, includes main body frame, motor and laterally zygomorphic two traction belts, and each guiding piece fixed outside of wherein said traction belt has the spill traction anchor clamps that adapt; Spill traction anchor clamps concave surface forms pulling face outwardly, and the spill traction anchor clamps of laterally zygomorphic two traction belts form cavity structure in correspondence with each other, and shape and shape of product are consistent; Described pulling face is provided with 5 shallow grooves; Transverse width is 3mm, and the degree of depth is 2mm, and its effect is (1) to prevent the guiding piece stress deformation; Because of stress deformation reduces guiding piece and extrudes the contact area of part, thereby reduce tractive force; (2) as at guiding piece and product surface product sawing or foreign material etc. being arranged, can play the effect of skidding of preventing.
Extrude the part draw-gear and also be provided with " adjusting rod ", can up-down adjustment on traction belt in the distance of vertical direction, described traction clamping adjusting rod is M24 * 1.5, is installed in each one of forward and backward the right and left of hauling machine, amounts to 4.Through the up-down adjustment adjusting screw(rod), guaranteeing the product steady production, under the constant situation of tractive force, the suffered normal pressure of product this moment is minimum, can not receive the influence of air pressure fluctuation to the traction normal pressure simultaneously.
