Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in fig. 1-4, the new process for forming and manufacturing the three-wire aluminum corrugated pipe sleeve is characterized by comprising the following process flows: aluminum plate-cold-bending roll-forming process-six corrugated groove profile-spin-forming process-three-line corrugated pipe sleeve.
The cold-bending roll-forming process comprises the steps of determining the outline parameters of the corrugated groove and roll-forming, wherein the number of the convex grooves of the corrugated groove is 6, the central line of the middle groove 4 is taken as a reference, 3 convex grooves are uniformly distributed on two sides, and the groove width of one side is larger than that of the other side.
The corrugated groove forming method in the rolling forming procedure adopts a symmetrical rolling forming sequence, firstly, the middle groove 4 is rolled and formed, and then the grooves on two sides are sequentially symmetrically rolled and formed by taking the middle groove 4 as a reference.
Sleeve spin forming realize through drum and spinning wheel meshing, spinning wheel totally six, the equipartition is in the drum is all around, realizes the direction to corrugated groove spin forming, every spinning wheel profile includes two parts, partly is used for the direction, and its profile cross-section roll type is unanimous with the last roll-in shaping pass compression roller type of corrugated groove, another part is the optical axis for roll-in shaping after the direction to the corrugated groove, the optical axis radius is along with roll-in shaping direction progressively increase.
The invention aims to provide a novel process for manufacturing and forming a three-wire aluminum corrugated pipe sleeve. The process flow is realized as shown in figure 1.
The aluminum plate used in the new process for manufacturing the aluminum cylinder is a coil, the aluminum plate is fed by an uncoiler, the width of the aluminum plate is determined to be 100mm according to the number and the depth of the corrugated grooves and the performance requirement of the sleeve, and the thickness of the aluminum plate is 0.5 mm.
The cold-bending roll-forming process mainly comprises two parts of corrugated groove profile parameter determination and roll-forming method design. In order to realize seamless connection among time slots during subsequent corrugated groove spinning forming, the number of the grooves of the profile section of the corrugated groove is twice of the number of the thread lines of the spinning wheel. The number of the grooves is small, the spinning forming efficiency is low, the number of the grooves is large, the efficiency is high, but the volume and the cost of the spinning device are correspondingly increased, and the spinning forming quality is difficult to ensure, so that the number of the corrugated groove bulges and the number of the grooves are respectively designed to be 6 and 7, the number of the spinning rollers is 3, and the thread pitch is 8. Meanwhile, for the convenience of sleeve spinning forming, the groove width adopts asymmetric design, namely under the condition that the thread pitches are equal, the central line of the middle groove 4 is taken as a reference, the three thread grooves are respectively positioned at two sides, the groove widths are not equal, the widths of the three convex grooves at the left side are smaller, correspondingly, the widths of the convex grooves at the right side of the compression roller are larger, the three pairs of wide grooves 5, 6 and 7 are correctly meshed with the corresponding three pairs of narrow grooves 1, 2 and 3 during subsequent spinning forming, and the sectional profile of the six corrugated grooves and the corresponding geometric model of the compression roller are respectively shown in fig. 2.
The rolling forming method directly influences the forming quality and efficiency of the corrugated groove and is one of key technologies related to influencing the forming quality of the corrugated pipe sleeve. In the process of rolling a flat aluminum plate into a corrugated groove, the flat aluminum plate slides and rubs between the profiles of the rolling wheels due to continuous shrinkage, and for the rolling of the corrugated groove with the number of single-groove or concave grooves less than 3, a simultaneous rolling forming method is generally adopted for improving the rolling efficiency. For the multi-line corrugated grooves with the number of concave grooves larger than 3, if a simultaneous rolling forming method is adopted, the degree of freedom of contraction of the plate among different groove profiles of the pressing roller is restricted in the rolling process, and the plate is interfered to generate a tearing defect. Therefore, the roll forming method adopts a symmetrical roll forming mode, namely, the middle groove 4 is firstly roll formed, and then the grooves on the two sides are respectively roll formed by taking the middle groove 4 as a reference. Fig. 3 shows a six-corrugation groove profile rolling forming sequence, which comprises 13 passes in total for realizing the rolling forming of 6 convex corrugation grooves and 7 concave corrugation grooves, wherein 0 pass only plays a guiding role, and the other passes are equally divided into 3 groups, and the rolling forming of the middle groove 4 and the grooves 3 and 5 on the two sides, 2 and 6, 1 and 7 are respectively carried out in sequence.
The sleeve spinning forming process is designed according to the principle of thread transmission and is mainly realized by meshing a drum wheel and a spinning wheel. The design method can realize corrugated groove guiding and ensure sleeve forming quality, and is shown in figure 4. In order to meet the guiding of the spinning forming movement of the corrugated groove sleeve, 6 spinning wheels are uniformly distributed around the drum wheel at intervals of 60 degrees.
