Description

Technical Field

[0001] The utility model relates to the technical field of steel strand production, in particular to a carving device for slow-bonding steel strands. Background Art

[0002] Traditional steel strands are of two types: unbonded and bonded. The slow-bonded prestressing technology combines the characteristics of the two systems to improve the relevant structural types. It is composed of prestressed tendons (steel strands or steel wire bundles), slow-bonded adhesive and outer protective sheath. The slow-bonded adhesive is filled between the outer protective sheath and the prestressed tendons. When producing slow-bonded steel strands, it is also necessary to press out orderly concave and convex corrugations on the outside of the outer protective sheath, so as to increase the wrapping tightness of the prestressed tendons.

[0003] Affected by the production environment, impurities will adhere to the outside of the outer protective sheath of the slow-bonding steel strand during production. After searching, the patent with the publication number of CN104499325A was found to have no function of cleaning the impurities adhered to the outer protective sheath when pressing the corrugations on the outer side of the outer protective sheath. In this way, the impurities will scratch the outer protective sheath during pressing, affecting the service life of the outer protective sheath, so it is necessary to make improvements;

[0040] An embossing assembly, which is mounted on the base plate 1;

[0041] The cleaning brush 5 is slidably connected to the connecting rod 4;

[0042] In this embodiment, the two motors 7 are controlled to work to rotate the two turntables 9. Under the action of the two pull rods 12, the two turntables 9 rotate to pull the two cleaning brushes 5 to move left and right continuously, so that the impurities outside the outer protective cover can be cleaned. In this way, the device has the function of cleaning impurities.

[0043] In order to achieve the purpose of supporting the fan 13, the device adopts the following technical solution: a stabilizing plate 14 is fixedly connected to the rear side of the bottom plate 1, and the fan 13 is fixedly embedded inside the stabilizing plate 14, and the stabilizing plate 14 can support the fan 13;

[0044] Among them, in order to achieve the purpose of embossing, the device adopts the following technical solutions: the embossing component includes a U-shaped frame 15, the U-shaped frame 15 is fixedly connected to the top of the bottom plate 1 and is located on the other side of the support plate 2, the bottom of the bottom plate 1 is fixedly connected to the motor 2 16, and the top of the U-shaped frame 15 is embedded with two rotating shafts 17, the bottom ends of the two rotating shafts 17 both penetrate the bottom plate 1 and the bottom end of one of the rotating shafts 17 is fixedly connected to the output shaft of the motor 2 16, the tops of the two rotating shafts 17 are fixedly sleeved with embossing wheels 18, the outsides of the two rotating shafts 17 are fixedly sleeved with gears 19, and the two gears 19 are meshed and connected;

[0047] The use process of the utility model is as follows: when embossing work is required, the slow-bonding steel strand is passed through two rollers 21 one, through hole two, two cleaning brushes 5, through hole two and two embossing wheels 18 from left to right in sequence, such as Figure 5 As shown, the second motor 16 is then controlled to work so that the second rotating shaft 17 and the rear gear 19 on the rear side can rotate, and the rotation of the rear gear 19 drives the front gear 19 to rotate, and the rotation of the front gear 19 drives the second rotating shaft 17 on the front side to rotate, so that the two second rotating shafts 17 can rotate at the same time, thereby driving the two embossing wheels 18 to rotate, and the second motor 16 is controlled to make the embossing wheel 18 on the rear side rotate counterclockwise and the front side rotate clockwise (from a top view), so that the slow-bonding steel strand can be transported to the right while the embossing work is performed;

[0048] When the motor 2 16 is working, it controls the two motors 1 7 to work, so that the two rotating shafts 1 8 can be driven to rotate, and the rotation of the two rotating shafts 1 8 drives the two turntables 9 to rotate. Since the pull rod 12 and the connecting rod 1 10 and the connecting rod 2 11 are movable through the bearing connection, the two turntables 9 can be pulled to move left and right continuously under the action of the two pull rods 12. Since the outer protective cover of the slow-bonding steel strand is in contact with the two cleaning brushes 5, the two cleaning brushes 5 can move left and right to clean the impurities on the outside of the outer protective cover. In this way, the device has the function of cleaning impurities. At the same time, the fan 13 is controlled to work, so that the cleaned impurities can be blown away, thereby preventing the impurities from adhering to the outside of the outer protective cover again. In this way, the impurities can be prevented from scratching the outer protective cover during pressing, thereby preventing the service life of the outer protective cover from being reduced.
