Abstract
The utility model discloses a sheath for rolling and bending an aluminum tube. The sheath comprises an upper elastic nylon strip block and a lower elastic nylon strip block, wherein the upper elastic nylon strip block and the lower elastic nylon strip block are overlapped and two sides of the strip blocks are provided with steps which are fastened with each other; the bottom surface of the upper elastic nylon strip block and the top surface of the lower elastic nylon strip block are provided with grooves respectively; and after the upper elastic nylon strip block and the lower elastic nylon strip block are overlapped and fastened, the shape of the section of the combined grooves on the bottom surface of the upper elastic nylon strip block and the top surface of the lower elastic nylon strip block is matched with that of a section of the aluminum tube. The surface defects of the rolled and bent aluminum tube are effectively overcome, the sheath is particularly suitable for rolling and bending the aluminum tube with an irregular section, and the surface quality of the aluminum tube is guaranteed.
Description
Technical field
The utility model relates to a kind of aluminum pipe that is used for and rolls curved sheath.
Background technology
Aluminum pipe rolls the three-way roller of curved employing usually and rolls bending apparatus enforcement; General three-way roller rolls the bending apparatus bottom and is interval with two rollers; Above two rollers, be provided with a roller between two parties, three rollers rotate to a direction with identical speed, and aluminum pipe is between two bottom rollers and upper roller; Upper roller is depressed aluminum pipe is pressed between two bottom rollers; Roll rate of curving control upper roller according to aluminum pipe and depress distance, along with the rotation of roller, aluminum pipe roll forming and export three-way roller and roll bending apparatus between three rollers; Usually the roller material is that round steel is processed, and aluminum pipe rolls that roller and aluminum tube surfaces friction cause aluminum tube surfaces impression and scuffing when curved, has a strong impact on the surface quality of aluminum pipe.When particularly the aluminum pipe cross section was odd-shaped cross section, aluminum tube surfaces impression and scuffing more very made the odd-shaped cross section aluminum pipe roll on the bending apparatus and can't accomplish at three-way roller.
Summary of the invention
The utility model technical problem to be solved provides a kind of aluminum pipe that is used for and rolls curved sheath, utilizes this sheath effectively to avoid aluminum pipe to roll curved blemish, is particularly useful for the curved operation of rolling of odd-shaped cross section aluminum pipe, has guaranteed the surface quality of aluminum pipe.
For solving the problems of the technologies described above; The utility model is used for aluminum pipe and rolls curved sheath and comprise rectangular of elasticity dragon and imperial rectangular of following elasticity; Rectangular of said upward elasticity dragon and rectangular overlapping setting of following elasticity dragon and both sides are respectively equipped with the step of mutual fastening; The bottom surface that said upward elasticity dragon is rectangular is respectively equipped with groove with the end face of rectangular of following elasticity dragon; Behind rectangular of said upward elasticity dragon and rectangular overlapping fastening of following elasticity dragon, the said groove of the imperial rectangular bottom surface of elasticity and the cross sectional shape and the aluminum pipe cross sectional shape coupling of the groove combination of the imperial rectangular end face of following elasticity of going up.
Because the utility model is used for aluminum pipe and rolls curved sheath and adopted technique scheme; Be that this sheath comprises rectangular of elasticity dragon and imperial rectangular of following elasticity; Rectangular of last elasticity dragon and rectangular overlapping setting of following elasticity dragon and both sides are respectively equipped with the step of mutual fastening; The bottom surface that last elasticity dragon is rectangular is respectively equipped with groove with the end face of rectangular of following elasticity dragon; Behind rectangular of last elasticity dragon and rectangular overlapping fastening of following elasticity dragon, the cross sectional shape and the aluminum pipe cross sectional shape of the groove combination of rectangular end face of the groove of rectangular bottom surface of last elasticity dragon and following elasticity dragon mate.This sheath has effectively avoided aluminum pipe to roll curved blemish, is particularly useful for the curved operation of rolling of odd-shaped cross section aluminum pipe, has guaranteed the surface quality of aluminum pipe.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Fig. 1 is used for the structural representation that aluminum pipe rolls curved sheath for the utility model.
The specific embodiment
As shown in Figure 1; The utility model is used for aluminum pipe and rolls curved sheath and comprise rectangular 1 of elasticity dragon and imperial rectangular 2 of following elasticity; Rectangular 1 of said upward elasticity dragon and rectangular 2 overlapping setting of following elasticity dragon and both sides are respectively equipped with the step 3 of mutual fastening; The bottom surface that said upward elasticity dragon is rectangular 1 and the end face of imperial rectangular 2 of following elasticity are respectively equipped with groove 4,5; Behind rectangular 1 of said upward elasticity dragon and rectangular 2 overlapping fastening of following elasticity dragon, the cross sectional shape and the aluminum pipe cross sectional shape of the groove 4 of imperial rectangular 1 bottom surface of said upward elasticity and groove 5 combinations of imperial rectangular 2 end face of following elasticity mate.
Aluminum pipe rolls when bending operation; At first aluminum pipe is located in the groove of rectangular of last elasticity dragon and the imperial rectangular combination of following elasticity of this sheath; The length of rectangular of last elasticity dragon and imperial rectangular of following elasticity is with required to roll curved aluminum pipe length consistent; Rectangular groove with rectangular of following elasticity dragon of last elasticity dragon can adopt customization milling cutter processing and fabricating on lathe; Groove is according to the aluminum pipe cross sectional shape; Can be processed into rectangle, circle or other odd-shaped cross sections and with the aluminum pipe cross-sections match, rectangular of last elasticity dragon and rectangular fastening of following elasticity dragon be placed on three-way roller roll between two bottom rollers and the upper roller of bending apparatus the enforcement aluminum pipe roll curved, in the roll bending process; Upper roller directly contacts with end face of rectangular of last elasticity dragon and the bottom surface of rectangular of following elasticity dragon respectively with two bottom rollers; Rectangular of rectangular of last elasticity dragon and following elasticity dragon with aluminum pipe to roll the rate of curving crooked and rotate the three-way roller of output with roller and roll bending apparatus and accomplish aluminum pipe and roll curved operation, after aluminum pipe rolled curved the completion, imperial rectangular of rectangular of last elasticity dragon and following elasticity can be used for the curved operation of rolling of next aluminum pipe with the strain shape that resiles.This sheath has effectively protected aluminum pipe to roll the surface quality in the curved operation process, has avoided the impression and scuffing defective of aluminum tube surfaces, has guaranteed that aluminum pipe rolls curved quality.
