Description

Technical Field

[0001] This utility model belongs to the field of cold bending forming technology, and in particular relates to a cold bending forming track. Background Technology

[0002] In production, the transfer of products or goods is inseparable from transfer vehicles, which move on tracks to facilitate the transfer of products or goods. Currently, to reduce costs, some tracks use cold-formed steel plates. These tracks typically have a hollow support section with wing plates bent at the bottom. The track is fixed to the ground or frame via these wing plates, and the transfer vehicle is supported by the hollow support section. However, in use, it has been found that this type of track has problems with low support strength and poor load-bearing capacity. Under impact, both the hollow support section and the track itself are easily deformed, affecting the normal operation of the transfer vehicle. Therefore, how to optimize the design of the cold-formed track structure to improve its support strength and ensure the normal operation of the transfer vehicle has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0003] In view of this, the present invention aims to propose a cold-bent forming track to improve its support stability.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A cold-formed track includes a track body and a filler. The track body is a cold-formed steel plate structure, including a roller support part. The roller support part has an inner cavity with an opening facing downward. The roller support part is bent into a waist plate part at the opening position, which is obliquely downward to the left and obliquely downward to the right. The two waist plates are symmetrical and form a triangular support structure. The bottom ends of the two waist plates are bent outward horizontally to form wing plates.

[0006] The filler is an injection molded part, the shape of which corresponds to the inner cavity of the roller support, and the filler is disposed inside the inner cavity of the roller support.

[0007] Furthermore, the waist plate portion and the roller support portion are smoothly transitioned through an arc-shaped plate portion.

[0008] Furthermore, the horizontal inclination angle of the waist plate is 45° to 60°.

[0009] Furthermore, a number of stiffeners are evenly spaced on the outer surface of the waist plate along the track extension direction. The top of the stiffeners abuts against the roller support and is welded, and the bottom of the stiffeners abuts against the wing plate and is welded.

[0010] Furthermore, several connecting plates are evenly spaced between the two waist plates along the track extension direction, with the left and right edges of the connecting plates tightly attached to the inner surfaces of the two waist plates.

[0011] Furthermore, the opening of the corresponding roller support at the top of the connecting plate is provided with an extension, the extension extends into the roller support, and its top surface fits against the filler.

[0012] Furthermore, the top surface of the extension is a concave arc surface structure.

[0013] Compared with the prior art, the cold-bending formed track of this utility model has the following advantages:

[0014] (1) The present invention has a simple structure. The track body is a cold-bent steel plate structure, so the manufacturing cost is low. The roller support part is filled with filler to support the roller support part from the inside, thereby improving its resistance to deformation. The waist plate part on both sides forms a triangular support structure to support the roller support part, making the track load more uniform, improving the track support strength, and ensuring that the transfer vehicle runs normally along the track.

[0015] (2) In this utility model, the setting of stiffening plates and connecting plates improves the energy absorption effect of the track and enhances the track's bending resistance and deformation resistance. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cold-formed rail includes a rail body 1 and a filler 2. The rail body 1 is a cold-formed steel plate structure, including a roller support 11 for supporting a transfer vehicle. The roller support 11 has a downward-facing inner cavity, in which the filler 2 is disposed. The filler 2 is an injection-molded part, and its shape corresponds to the inner cavity of the roller support 11. The filler 2 internally supports the roller support 11, improving the strength and deformation resistance of the roller support 11. At the same time, the filler 2 itself has shock-absorbing properties, improving the rail's impact resistance. At its opening position, the roller support 11 is bent diagonally downwards to the left and downwards to the right, each forming a waist plate 12. The horizontal inclination angle of the waist plate 12 is preferably 45° to 60°, and the waist plate 12 and the roller support 11 are smoothly transitioned through an arc-shaped plate 14. The two waist plate sections 12 are symmetrical and form a flared structure with the opening facing downwards, that is, the two waist plate sections 12 form a triangular support structure. The bottom ends of the two waist plate sections 12 are bent outwards horizontally to form wing plate sections 13. Fixing holes are opened on the wing plate sections 13, and screws are used to fix the wing plate sections to the ground or frame, thereby installing and fixing the track.

[0026] In this utility model, the injection-molded filler in the roller support part 11 improves the strength and deformation resistance of the roller support part 11. The roller support part 11 is supported by two inclined waist plates 12, which improves the track support strength and impact resistance.

[0027] In this invention, a plurality of stiffening plates 3 are evenly spaced along the extension direction of the track on the outer surface of the waist plate portion 12. The stiffening plates 3 are thin steel plate structures, with their tops abutting against and welded to the roller support portion 11, and their bottoms abutting against and welded to the wing plate portion 13. This structure can further improve the track's own strength and impact resistance, ensure the track's support stability for the transfer vehicle, and ensure that the transfer vehicle can move smoothly on the track.

[0028] In this invention, several connecting plates 4 are evenly spaced between the two waist plate sections 12 along the track extension direction. The left and right edges of the connecting plates 4 are tightly attached to the inner surfaces of the two waist plate sections 12 and welded to the waist plate sections 12. The structure of the waist plate section 12 is as follows: Figure 5 As shown, the top of the connecting plate 4 has an extension 41 corresponding to the opening of the roller support 11. The top surface of the extension 41 is a concave arc-shaped structure 42. The extension 41 extends into the roller support 11, and the arc-shaped structure 42 fits against the filler 2. The lower edge of the connecting plate 4 protrudes above the bottom surface of the wing plate 13. The connecting plate 4 connects the two waist plates 12, improving the strength and impact resistance of the track at the waist plate position, thus stably supporting the transfer vehicle.

[0029] In this utility model, the track body adopts a cold-bent steel plate structure, the filling material in the roller support part, the triangular support structure formed by the waist plate part, and the setting of connecting plates and stiffening plates improve the track strength and deformation resistance, ensuring that the transfer vehicle runs smoothly on the track.
