Description

Technical Field

[0001] This utility model relates to the field of punching equipment, specifically a cold punching device for anchor bolt packaging accessories for wind turbine foundations. Background Technology

[0002] In recent years, to avoid stress concentration during wind turbine foundation connections, prestressed anchor cage structures have replaced foundation ring structures, leading to a rapid increase in demand for prestressed anchors. Prestressed anchor cage structures effectively prevent excessive local compressive stress in the concrete caused by deformation inconsistencies between the foundation steel and concrete in traditional foundation ring structures, thus avoiding crushing and damage and ensuring the safety of wind turbine foundations.

[0003] Based on the characteristics of anchor bolts used in wind turbine foundations, the product specifications are typically M36, M39, M42, and M48 in diameter, with lengths ranging from 3000mm to 6000mm. Larger anchor bolts, such as M56 and M64, have also become more common in recent years. Due to the specific characteristics of anchor bolts, they are generally packaged and shipped using connecting accessories such as channel steel, flat iron, and tie rods. With the increasing demand for anchor bolts, conventional punching equipment for drilling holes in the channel steel and flat iron can no longer meet customer delivery time requirements. Utility Model Content

It is specifically used for cold punching the channel steel and flat iron of anchor bolt packaging accessories for wind turbine foundations, solving the problem of slow drilling of anchor bolt accessories, supply shortage and high cost caused by the sudden increase in anchor bolt production.

[0005] This utility model provides a cold punching device for anchor bolt packaging accessories for wind turbine foundations, including a punch press, an upper punch installed on the upper and lower slides of the punch press, a special mold installed on the worktable of the punch press, the special mold located below the upper punch, a vertical mold through hole in the center of the special mold, the mold through hole being adapted to the punch head of the upper punch, and a horizontally opened slotted notch on the side of the special mold, the slotted notch allowing the raw material channel steel or raw material flat iron to pass through smoothly.

[0006] Furthermore, the diameter of the through hole in the mold is φ21mm, the outer diameter of the punch for punching is φ20.5mm, and the length of the punch for punching is two-thirds of the height of the special mold.

[0007] Furthermore, the arc of the punch in the punching process is coaxial with the through hole of the special mold, allowing the punch to move up and down freely within the through hole of the mold.

[0008] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0009] This utility model discloses a cold punching device for packaging anchor bolts for wind turbine foundations. The device uses a simple special mold structure, has low manufacturing cost, and punching is more than 5 times more efficient than drilling. It is suitable for the cold punching process of raw material channel steel and raw material flat iron that make up the packaging accessories for anchor bolts for wind turbine foundations. While ensuring processing quality and precision, it multiplies the production efficiency, ensures processing safety, and makes the packaging of anchor bolts for wind turbine foundations convenient and secure.

Detailed Implementation

[0015] To more clearly illustrate the technical solution and effects of this utility model, the present utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely some embodiments of this utility model, not all embodiments, and the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] It should be noted that the terms "installation", "connection", "linking", and "setting" should be interpreted broadly. For example, they can refer to fixed connection or setting, detachable connection or setting, or integrated connection or setting; they can refer to direct connection or indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0017] Please see Figure 1-3As shown, this embodiment provides a cold punching device for anchor bolt packaging accessories for wind turbine foundations, including a punch press 1, an upper punch 6 installed on the upper and lower sliders 2 of the punch press 1, a special mold 3 installed on the worktable of the punch press 1, the special mold 3 being located below the upper punch 6, a vertical mold through hole 5 in the center of the special mold 3, the mold through hole 5 being adapted to the punch head of the upper punch 6, and a slotted notch 4 being opened laterally on the side of the special mold 3, the slotted notch 4 allowing the raw material channel steel 7 or raw material flat iron 10 to pass smoothly.
