Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a U-shaped anchor bolt pressing tooling device. Background Technology

[0002] Pressed U-shaped anchor bolts are non-standard parts, mainly used in the installation of steel box girders to fix anti-collision columns, belonging to the field of building steel structures. They are made by pressing bolts with threads at both ends into a U-shape using a mold, allowing for mass production, greatly shortening the processing cycle and significantly reducing costs.

However, the quantity required at the installation site is very large, and the workshop's processing progress often cannot keep up with the demand. Therefore, the workshop needs to invest a lot of manpower and resources to process U-shaped anchor bolts, which seriously affects the overall production schedule.

[0004] The existing technology faces technical problems such as long production cycle, high time consumption, and high cost in manufacturing pressing molds for U-shaped anchor bolts of different specifications. Utility Model Content

Furthermore, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0030] Example 1: Combining Figure 1 and Figure 2 A U-shaped anchor bolt pressing fixture, characterized in that,

[0031] The tooling device includes an upper mold 1 and a lower mold 2;

[0032] The upper mold 1 includes an upper mold lower protrusion 6; the lower mold 2 includes a groove 12, and the upper mold lower protrusion 6 and the groove 12 can fit together.

The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows:

[0034] Considering the above reasons, the company decided to independently research, design, and manufacture a tooling device capable of pressing U-shaped anchor bolts of various specifications. During the tooling device manufacturing process, the company utilized its existing stock of scrap materials and workshop equipment to ensure low-cost tooling production. The tooling device is designed to press U-shaped anchor bolts of different specifications, is easy to disassemble, and is safe to use. Compared to heating and baking individual bolts, using this tooling device significantly reduces costs, enables mass production, meets production demands, ensures timely delivery, and improves product quality.

[0035] The upper mold is connected to the upper mold of the hydraulic press by fasteners, and the base is installed on the working platform of the hydraulic press. The upper and lower molds are installed, adjusted and calibrated according to the design requirements and then arranged symmetrically.

[0036] The upper mold consists of an upper connecting plate, a middle connecting piece, and a lower protrusion, and is convex in shape. The radius R of the lower mold corresponds to that of the upper mold, and is concave in shape, consisting of an upper concave piece, an adjuster, a reinforcing plate, a lifting lug, and stiffening ribs.

[0037] To meet the design drawings, the tooling was fabricated based on overall forming springback experience, taking into account the springback amount during U-shaped anchor bolt pressing, and determining the radius R and straight section values ​​of the upper and lower dies to ensure the spacing between the upper and lower dies during the forming process. Through continuous summarization of the number of pressing passes and tonnage values ​​for each U-shaped bolt during actual operation, a tooling device was finally manufactured, which plays a simple, convenient, economical, practical, and efficient role in the component production process.

[0038] During the pressing process, the parameters of the left and right adjusters are used to press U-shaped anchor bolts of different specifications. This allows a single mold to meet the pressing needs of different specifications of U-shaped anchor bolts, achieving high efficiency and gain.

[0039] The tooling device for pressing U-shaped anchor bolts is equipped with a 1000-ton hydraulic press, which can press U-shaped anchor bolts with a diameter range of Φ30mm~Φ50mm.

[0040] Example 2: As a further improvement, parallel, or optional independent solution, the vertical cross-sections of the upper mold lower protrusion 6 and the groove 12 are both U-shaped. The substantial technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: it facilitates molding.

[0041] Example 3: As a further improvement, parallel, or optional independent solution, the vertical cross-sectional geometry of the upper mold lower protrusion 6 and the groove 12 both include rounded corners. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, is as follows: to avoid damage to the reinforcing steel.

[0042] Example 4: As a further improvement, parallel, or optional independent solution, the upper mold is connected to the upper mold of the hydraulic press by fasteners, and the base of the lower mold 2 is installed on the working platform of the hydraulic press.

[0044] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0045] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.
