Description
Technical Field
The utility model belongs to car sealing strip roller shear skeleton equipment production field, concretely relates to car sealing strip roller shear skeleton tension mechanism.
Background
The stretching of the automobile sealing strip rolling shear framework is that the rotating speed of the compression rollers is controlled by a servo motor, the compression rollers drive raw materials sheared by the rollers to move forwards, the rotating speeds of the two compression rollers are different from low to high, and the raw materials sheared by the rollers are stretched by utilizing the speed difference and the ductility of the raw materials so as to reach the pre-designed shape; theoretically, the longer the length of the raw material between the two compression rollers, the larger the stretching ratio is, the more stable the stretching is, but sometimes due to the limitation of the field, the distance between the two compression rollers cannot be adjusted, and only the rotating speed difference between the two compression rollers can be increased, but the stretching is not stable, the pulling is easy to break, and the yield is low.
SUMMERY OF THE UTILITY MODEL
In order to overcome the problem that exists among the above-mentioned prior art, the utility model aims at providing a roll and cut skeleton tension mechanism, this mechanism mainly is suitable for and uses under the situation of the unable adjustment of interval between narrow and small, two compression rollers in the scene to tensile even, steady, the strip is difficult to the fracture in tensile process, and the yield increases substantially.
In order to achieve the purpose, the technical scheme adopted by the invention is to improve the original stretching mechanism and stretch the raw material by utilizing the vertical space between two press rolls and the traction force of a pulley on the raw material.
The utility model provides a roller shear skeleton tension mechanism, includes first drawing roller set (1), second drawing roller set (2), workstation (3), first drawing roller set (1) and second drawing roller set (2) set up on workstation (3), still are provided with riser (4) on workstation (3), riser (4) are located between first drawing roller set (1) and second drawing roller set (2), and riser (4) side is fixed with mated fixed axle (6), and slide bearing (7) are established to fixed axle (6) overcoat.
The utility model discloses in, first drawing roller set (1) and second drawing roller set (2) all include two drawing rollers that set up from top to bottom.
The utility model discloses in, riser (4) lower part is equipped with gusset (5), gusset (5) respectively with riser (4), workstation (3) fixed connection.
The utility model discloses in, riser (4) unilateral sets up the gusset or two sides set up the gusset.
The utility model has the advantages of: utilize the utility model discloses a car sealing strip roller shear skeleton of tensile mechanism production, the size is even, tensile steady, takes the material to be difficult to the fracture in tensile process, and the yield can increase substantially.

Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The utility model provides a roller shear skeleton tension mechanism, includes first tensile roller set 1, the tensile roller set 2 of second, workstation 3, first tensile roller set 1 and the tensile roller set 2 setting of second are on workstation 3, still are provided with riser 4 on workstation 3, riser 4 is located between the tensile roller set 2 of first tensile roller set 1 and second, and 4 sides of riser are fixed with mated fixed axle 6, and slide bearing 7 is established to the 6 outer zero clearance cover of fixed axle, and tensile raw and other materials 8 penetrate first tensile roller set 1 earlier, then S-shaped winding is on slide bearing 7, wears out from the tensile roller set 2 of second at last. The first and second draw-roll groups 1 and 2 each comprise two draw rolls arranged one above the other. The lower part of the vertical plate 4 is provided with a rib plate 5, and the rib plate 5 is respectively fixedly connected with the vertical plate 4 and the workbench 3. The number of the fixed shafts 6 is determined according to actual production needs, but must be present in pairs. The number of the sliding bearings 7 mounted on each fixed shaft 6 is determined by the width of the raw material 8 to be drawn, but it is necessary to ensure that the entire width surface of the raw material to be drawn slides on the sliding bearings.
The utility model discloses an installation and production process of tension mechanism do:
step 1: the first drawing roller group 1 and the second drawing roller group 2 are arranged on a workbench 3;
step 2: the vertical plate 4 and the rib plate 5 are arranged on the workbench 3;
and step 3: the rib plate 5 is connected with the vertical plate 4;
and 4, step 4: the fixed shaft 6 is fixed on the vertical plate 4;
and 5: the sliding bearing 7 is sleeved on the fixed shaft 6 without a gap;
step 6: the raw material 8 is firstly inserted into the first drawing roller group 1, then S-shaped wound on the sliding bearing 7 and finally threaded out of the second drawing roller group 2;
and 7: starting a motor to enable the first drawing roller group 1 and the second drawing roller group 2 to start to operate;
and 8: the raw material is driven to move forward under the joint operation of the first drawing roller group 1 and the second drawing roller group 2, and the raw material is drawn.
The stretching mechanism can be used in the situations of narrow field and incapability of adjusting the distance between the two compression rollers, and can also be used in the situation of large space, after the stretching mechanism is used, the stretching ratio of the framework of the automobile sealing strip is increased, the space between the two compression rollers is uniform, the strip is not easy to break, and the yield is greatly improved.
What has been described above is only a preferred embodiment of the present invention, and is not limited to the present invention. It should be noted that other modifications and equivalents may be made by those skilled in the art in light of the teachings of the present disclosure to achieve the same purpose, and should be construed as within the scope of the present disclosure.
