Abstract
Description
Technical Field
[0001] The utility model relates to cold-rolled steel bar feeding equipment, in particular to a feeding auxiliary device for preventing steel bars from coiling during feeding, belonging to the technical field of rolling equipment. Background Art
[0002] In cold-rolled ribbed steel bar production equipment, the function of the feeding machine is to pull out the coiled hot-rolled wire rod raw material from the head, straighten and descale it, and then send it to the subsequent rolling area. In production practice, a vertical feeding machine is commonly seen. The structure of a simple vertical feeding machine is as shown in the appendix Figure 1 It is mainly composed of a feeding frame 1, a core barrel 2, a top pulley 3 and a bottom pulley 4. After the steel bar 5 is pulled out, it passes through the top pulley and the bottom pulley in sequence and is sent to the subsequent equipment. The two groups of pulleys also have the function of descaling. The vertical feeding machine can make full use of the free gravity of the steel bar during the pulling process, which can eliminate part of the coiling accidents caused by the mutual nesting of steel bars. Its failure rate is not high and it can adapt to a relatively high production speed. However, due to the shape deformation of the coils caused by the production, hoisting and transportation of the hot-rolled wire rod, and the various shapes, the vertical feeding machine cannot eliminate all the coiling accidents caused by the mutual nesting of steel bars, and the occurrence of coiling accidents will reduce the production efficiency. Summary of the Invention
[0003] The purpose of the utility model is to avoid coiling accidents in vertical feeding, and to provide an auxiliary device for a vertical feeding machine.
[0004] To achieve the purpose of the utility model, the following technical solution is adopted: an auxiliary device for a vertical feeding machine, the vertical feeding machine includes a feeding frame and a core barrel, the auxiliary device includes a fixed ring fixedly connected to the feeding frame, the fixed ring is located above the core barrel, and a plurality of long strip-shaped elastic bodies are fixedly installed on the fixed ring. All the elastic bodies are inclined upward, and the included angle between the elastic body and the horizontal plane is an acute angle. The direction of the projection of the elastic body on the horizontal plane is as follows: taking the connection point of the elastic body and the fixed ring as point P, making a tangent line in the tangential direction of the steel bar spiral direction along point P, and the included angle between the projection of the elastic body on the horizontal plane and the tangent line is an acute angle.
[0005] Furthermore, the number of the elastic bodies is four, and the four elastic bodies are evenly distributed on the fixed ring.
[0006] Furthermore, the fixed ring is located on the horizontal plane.
[0007] The positive and beneficial technical effects of the utility model are as follows: during the feeding operation, the spiral-ring-shaped steel bar passes through the middle of the annular body, the outer circle of the steel bar intermittently collides with the elastic body, the elastic body swings back and forth and continuously hits the steel bar, and the nested steel bars can be pulled out orderly during the hitting and vibration process, avoiding coiling and reducing the equipment accident rate. Description of the Drawings

[0010] To more fully explain the implementation of the utility model, implementation examples of the utility model are provided. These implementation examples are only elaborations of the utility model and do not limit the scope of the utility model.
[0011] In combination with the accompanying drawings, the utility model is further explained in detail. The marks in the drawings are: 1: loading rack; 2: core cylinder; 3: top pulley; 4: bottom pulley; 5: steel bar; 6: fixing ring; 7: first elastic body; 8: second elastic body; 9: third elastic body; 10: fourth elastic body.
[0012] As shown in the accompanying drawings, an auxiliary device for a vertical loading machine, the vertical loading machine includes a loading rack 1 and a core cylinder 2. The auxiliary device includes a fixing ring 6 fixedly connected to the loading rack. The fixing ring is located on a horizontal plane and above the core cylinder. A plurality of long strip-shaped elastic bodies are fixedly installed on the fixing ring. In this embodiment, there are four elastic bodies, and the four elastic bodies are evenly distributed on the fixing ring. The four elastic bodies are the first elastic body shown in 7, the second elastic body shown in 8, the third elastic body shown in 9, and the fourth elastic body shown in 10. All the elastic bodies are inclined upward, and the angle between the elastic body and the horizontal plane is an acute angle. The direction of the projection of the elastic body on the horizontal plane is as follows: taking the connection point of the elastic body and the fixing ring as point P, making a tangent at point P in the same direction as the tangential direction of the steel bar helix. The angle between the projection of the elastic body on the horizontal plane and the tangent is an acute angle. Figure 2 The helix direction of the steel bar in is right-handed, and the arrow indicates the tangent of the steel bar helix direction at point P. Taking the first elastic body as an example, on Figure 2 In the case of right-handed rotation, the first elastic body slopes downward. If the steel bar is left-handed, the first elastic body becomes sloping upward in the case of left-handed rotation. There are many elastic bodies in the prior art for the utility model. For example, existing cylindrical tension springs can be used, and a flexible rubber cylinder can be wrapped outside the cylindrical spring.
