Description

Technical Field

[0001] The utility model relates to the technical field of steel bar chamfering, and more specifically, to a chamfering device for steel bar production. Background Art

[0002] Chamfering refers to the machining of cutting the edges of a workpiece into a certain inclined plane. Chamfering is to remove the burrs generated by machining on the part, and also for the convenience of part assembly. Generally, chamfers are made at the ends of the parts.

[0003] In the production process of steel bars, the steel bars will be cut into a certain length. After cutting, there will be many burrs on the cutting ends of both ends of the steel bars. In order to avoid burrs scratching fingers, a chamfering device is needed to chamfer the cutting surface. However, the current chamfering equipment cannot automatically clamp steel bars with different diameters, and during the processing, manual pushing of the position of the steel bars is required, resulting in low efficiency and high danger coefficient.

[0030] Embodiment 2 of a chamfering device for steel bar production according to the present utility model

[0031] Refer to, specifically as Figure 3 and Figure 4, a moving seat 3004 is connected between a pair of the sliders 3003, and connecting plates 3005 are connected to both sides of the top of the moving seat 3004. A push plate 3006 is installed between a pair of the connecting plates 3005. A rack 3007 is connected between a pair of the fixed blocks 3001.

[0032] Specifically, the working principle of this chamfering device for steel bar production: when chamfering the steel bar, place the steel bar between two pairs of clamping rods 2010, and then start a pair of cylinders 2003 to drive the wedge blocks 2008 to move upward. During the movement, a pair of moving rods 2006 move on the limiting rods 2006 to limit the movement of the wedge blocks 2008. During the movement, the wedge blocks 2008 push the bottom ends of a pair of clamping rods 2010, causing the bottom ends of a pair of clamping rods 2010 to move to both sides. The lower ends of a pair of clamping rods 2010 become larger, and the upper ends become smaller, clamping and fixing the steel bar. And the support rod 2012 supports the bottom of the steel bar. Then start the first motor 1005 to drive the rotating rod to rotate, driving the grinding disc 1007 to rotate to grind the steel bar. After grinding is completed at a fixed position, start the second motor 3009 to drive the rotating shaft 3010 to rotate, so that the gear 3011 rotates. The gear 3011 meshes with the rack 3007. When the gear 3011 rotates, it drives the moving seat 3004 and the push plate 3006 to move. The push plate 3006 can push the steel bar forward during the movement, so that the grinding disc 1007 can grind the remaining positions of the steel bar, improving the convenience of use.

[0033] It should be noted that the specific model specifications of the first motor 1005, the cylinder 2003 and the second motor 3009 of a chamfering device for steel bar production need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail.

[0034] The power supply and principle of the first motor 1005, the cylinder 2003 and the second motor 3009 of the chamfering device for steel bar production are clear to those skilled in the art and will not be described in detail herein.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
