DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the embodiment, Figure 1 and 2A thread rolling device for steel bar production is provided, comprising a workbench 1, wherein four universal wheels 2 are arranged at the bottom end of the workbench 1, four fixed seats 3 are fixedly connected to the top end of the workbench 1, a sliding rod 4 is fixedly connected between two adjacent fixed seats 3, the outer sides of the two sliding rods 4 are fixedly connected to a sliding base 5, a reduction motor 6 is fixedly connected to the top end of the sliding base 5, a thread rolling turntable 7 is fixedly connected to the outer side of the output end of the reduction motor 6, and a clamping assembly 8 is arranged at the top end of the workbench 1;

[0021] The clamping assembly 8 includes a clamping seat 81, a guide rod 82, a first clamping plate 83, a second clamping plate 84, clamping teeth 85, a lead screw 86 and a turning handle 87. The top of the workbench 1 is fixedly connected to the clamping seat 81, and the inner side of the clamping seat 81 is fixedly connected to two guide rods 82, the outer sides of the two guide rods 82 are fixedly connected to the first clamping plate 83, and the outer sides of the two guide rods 82 are slidingly connected to the second clamping plate 84. A plurality of clamping teeth 85 are provided on the opposite sides of the first clamping plate 83 and the second clamping plate 84. The inner side of the clamping seat 81 is rotatably connected to a lead screw 86, and the front end of the lead screw 86 is fixedly connected to a turning handle 87. The lead screw 86 is rotatably connected to the inner side of the first clamping plate 83, and the lead screw 86 is threadedly connected to the inner side of the second clamping plate 84.

[0022] With the above arrangement, the steel bar is placed between the first clamping plate 83 and the second clamping plate 84 and extended into the thread rolling turntable 7, and the handle 87 is turned to make the screw 86 rotate along the inner side of the clamping seat 81. At this time, the second clamping plate 84 will slide backward along the outer side of the two guide rods 82 until the first clamping plate 83 and the second clamping plate 84 The several clamping teeth 85 clamp the steel bar firmly, start the reduction motor 6, and the thread rolling turntable 7 is driven by the reduction motor 6 to rotate, and the steel bar is threaded by the thread rolling turntable 7. It should be noted that the screw 86 is rotatably connected to the inner side of the clamping seat 81 and is limited to the inner side of the clamping seat 81, and no displacement in the front and rear directions will occur. In addition, the screw 86 and the handle 87 have their own weight. If the handle 87 is not turned manually, the screw 86 will not rotate. Since the thread rolling turntable 7 of this device is relatively short, it is only suitable for thread rolling operations of short steel bars.

[0023] Reference Figure 1 and 2 , wherein a tray 9 located below the thread rolling turntable 7 is placed on the top of the workbench 1;

[0024] With the above-mentioned structural arrangement, the debris always generated during the thread rolling process will fall from the groove of the thread rolling turntable 7 into the tray 9. When a large amount of debris falls from a certain part of the tray 9, the sliding base 5 can be manually pushed to slide along the outer sides of the two slide bars 4 to avoid the accumulation of debris affecting the normal thread rolling. It should be noted that the sliding base 5 together with the reduction motor 6 has a heavy weight, and the sliding base 5 will not be displaced without external force.

[0025] Reference Figure 1 and 2 , wherein the top of the workbench 1 is fixedly connected to two baffles 10 respectively located at the front and rear sides of the thread rolling turntable 7;

[0026] Through the above-mentioned structural arrangement, the baffle 10 can prevent debris from splashing during the thread rolling process.
