Description

Technical Field

[0001] This utility model belongs to the field of forging technology, and in particular relates to a water-cooled tooling mold for forging clamp heads. Background Technology

[0002] During continuous forging, the mold temperature rises rapidly. Excessive temperature can cause thermal fatigue cracks and reduced lifespan. Traditional water-cooling designs are prone to causing localized stress concentration. If a spiral water-cooling module is installed in the mold, the cooling uniformity will be poor. For example, if the distance between the inlet and outlet is long, the cooling water temperature will be different, resulting in poor uniformity. In addition, if the mold with an integral water-cooling module is damaged, the entire mold needs to be scrapped, which is not only inconvenient to maintain but also too costly. Summary of the Invention

[0003] The purpose of this utility model is to provide a water-cooled tooling mold for forging clamp heads. By designing a large number of cooling mechanisms, each cooling mechanism is used to cool a corresponding area, realizing modular cooling. Each module can be controlled independently. At the same time, each module is arranged vertically, and the corresponding cooling area has strong uniformity. This avoids the problem of poor uniformity caused by excessively long water cooling channels, improves the cooling effect and efficiency, and ensures the mold's performance and lifespan.

[0009] The middle shell is disposed between the two end shells. The middle shell is an arc-shaped shell. The outer side of the middle shell has an outer cutout. The middle shell has several middle partition strips inside. Both ends of the middle shell are open surfaces and are welded to the open surfaces of the two end shells. The several middle partition strips are welded to several end partition strips.

[0010] The cover plate covers the outside of the outer cut, and the cover plate is fixed to the outside of the middle shell and the two end shells by welding. The inner side of the cover plate is provided with an inner padding layer with a gap set in the outer cut.

[0011] The end spacers and middle spacers on the cooling mechanism form a serpentine channel in the two end shells and the middle shell, and metal pipes that communicate with the two ends of the serpentine channel are fixed through both sides of the cover plate.

[0012] Several of the aforementioned arc-shaped pads are disposed inside the operating port and are respectively located outside several cooling mechanisms. Each arc-shaped pad has a through-hole on both sides, and the metal connecting pipe is located inside the through-hole.

[0013] Furthermore, the inflection point of the serpentine channel is located at the end of the end spacer, and the end spacer is provided with an inflection point through-hole.

[0014] Furthermore, a forming opening is provided at the center of the mold body, and the wall thickness between the forming opening and the mounting cavity is set in the range of 3-5cm.

[0015] Furthermore, the height of the operating port is greater than the height of the end shell, and the height of the end cavity is less than the height of the end shell.

[0017] Furthermore, a temperature sensor is installed within the serpentine channel.

[0019] 1. This utility model achieves modular cooling by designing a large number of cooling mechanisms, each of which cools a corresponding area independently. Each module can be controlled independently, and each module is arranged vertically, resulting in strong uniformity of the corresponding cooling area.
