Description

Technical Field

[0001] The utility model relates to the technical field of double-station clamps for processing steel bars, and specifically relates to a double-station clamp for processing steel bars. Background Art

[0002] In the prior art, the main problem with the double-station clamp for steel bar processing during use is that its contact area is relatively small, which may cause unnecessary damage to the surface of the clamp or the steel bar when clamping the steel bar. This is particularly common in high-strength steel bar processing operations, because such operations often require the clamp to provide a greater clamping force to ensure the stability of the steel bar during processing. When the contact area of ​​the clamp is small, the clamping force will be concentrated in a smaller area, increasing the pressure per unit area, thereby increasing the risk of wear and damage to the surface of the steel bar or the clamp.

[0003] In addition, due to the small contact area, the clamp may produce uneven pressure distribution during the clamping process, resulting in unstable clamping, affecting the processing accuracy and quality of the steel bars. This instability may cause dimensional deviations during the cutting, bending or other processing of the steel bars, affecting the overall safety and durability of the building structure. At the same time, frequent damage and uneven clamping may also shorten the service life of the clamp, increase maintenance costs and replacement frequency. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The clamping mechanism provides a stable and flexible clamping capability for the steel bars. In the clamping mechanism, the slider, the clamping spring, the insert rod, the compensation ring and the lateral spring work together to ensure that the steel bars can get appropriate pressure during the clamping process without causing surface damage.

[0026] See also Figure 1-5A double-station clamp for steel bar processing includes a fixed sleeve 1, which is installed on external equipment. A clamping mechanism is arranged on the fixed sleeve 1, and the clamping mechanism includes a tightening seat 2, a slider 3, a clamping spring 4, an insertion rod 5, a compensation ring 6, a lateral spring 7, a receiving mechanism and a contraction mechanism. A clamping groove 8 is provided in the fixed sleeve 1, and a plurality of tightening seats 2 are provided, and the plurality of tightening seats 2 are respectively installed in the clamping groove 8. A slide groove 9 is provided on each tightening seat 2, and the slider 3 is slidably connected in the slide groove 9. The compensation ring 6 is installed on the clamping spring 4, and the two ends of the clamping spring 4 are respectively installed with insertion rods 5. The two ends are respectively connected to the side walls of the slider 3, and the receiving mechanism and the contraction mechanism are respectively installed in the fixed sleeve 1. The receiving mechanism includes a follower block 10 and a push spring 11. The follower block 10 is slidably connected in the clamping groove 8. A push spring 11 is installed on the follower block 10, and the push spring 11 abuts on the slider 3. There are multiple push springs 11, and the multiple push springs 11 respectively abut on multiple sliders 3. A guide strip 12 is provided on the side wall of the follower block 10, and a guide groove 13 is opened in the clamping groove 8. The guide strip 12 is slidably connected in the clamping groove 8. Multiple clamping springs 4 and lateral springs 7 respectively abut on the side walls of the steel bar.

[0027] In this embodiment, when clamping, the push spring 11 drives the movement of the slider 3. Since the slider 3 slides along the tightening seat 2 and shrinks in the opposite direction toward the axis, the push spring 11 can compensate for the expansion and contraction. Then, it drives multiple retaining springs 4 to contact the side wall of the steel bar. The outermost slider 3 is installed with a lateral spring 7, which contacts the steel bar. The compensation ring 6 can compensate for the shrinkage of the retaining spring 4, thereby ensuring the stability of the clamping of the retaining spring 4 and the steel bar.

[0028] See also Figure 2 and Figure 3 As an implementation of the contraction mechanism: the contraction mechanism includes a hydraulic cylinder 14 and a connecting block 15, the hydraulic cylinder 14 is installed on the side wall of the fixed sleeve 1, and the connecting block 15 is installed on the protruding end of the hydraulic cylinder 14. There are two contraction mechanisms, and the two contraction mechanisms are symmetrically installed on both sides of the fixed sleeve 1. Transverse grooves 16 are respectively opened on both sides of the fixed sleeve 1, and transverse plates 17 are slidably provided in the transverse grooves 16. The two ends of the transverse plate 17 are respectively connected to the follower block 10 and the connecting block 15.

[0029] More specifically, when it is necessary to push the follower block 10 to move, the hydraulic cylinders 14 on both sides can synchronously drive the two connecting blocks 15 to slide. Due to the symmetrical arrangement of the two hydraulic cylinders 14, the follower block 10 can slide backward stably, and the guide bar 12 is slidably connected in the guide groove 13. Since the push spring 11 is installed on the follower block 10, the slider 3 can be pushed, thereby ensuring the fixing process.

[0030] In summary, when the clamp is used: the push spring 11 is used to drive the movement of the slider 3 during clamping. Since the slider 3 slides along the tightening seat 2 and shrinks in the opposite direction toward the axis, the push spring 11 can compensate for the expansion and contraction. Then, multiple retaining springs 4 are driven to contact the side wall of the steel bar. A lateral spring 7 is installed on the outermost slider 3. The lateral spring 7 contacts the steel bar. The compensation ring 6 can compensate for the shrinkage of the retaining spring 4, thereby ensuring the stability of the clamping of the retaining spring 4 and the steel bar.

[0031] When it is necessary to push the follower block 10 to move, the hydraulic cylinders 14 on both sides can synchronously drive the two connecting blocks 15 to slide. Due to the symmetrical arrangement of the two hydraulic cylinders 14, the follower block 10 can slide backward stably, and the guide bar 12 is slidably connected in the guide groove 13. Since the push spring 11 is installed on the follower block 10, the slider 3 can be pushed, thereby ensuring the fixing process.

[0032] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
