摘要： Disclosed is a press-cure mold cooling device with an improved structure to be able to slow down the cooling rate of a trim cut during a pressing process of a steel sheet blank in the production of parts for press cure. The press-cure mold cooling device according to the present invention comprises: a mold for press cure, which includes an upper mold and a lower mold, each having a cooling water supply section therein for press forming of a steel sheet blank by upward and downward stroking; and cooling water temperature regulation means disposed between contact surfaces, the contact surfaces being respectively formed between the cooling water supply sections in the upper and lower molds and the steel sheet blank, so as to regulate the temperature of cooling water being delivered to the steel sheet blank. Accordingly, the present invention is advantageous in that the cooling rate transmitted from the cooling water supply sections of the upper and lower molds can be delayed to prevent the trim cut from being quenched and thus being transformed into a martensite texture having high hardness, so that the wear on a trimming mold during a trimming process may be reduced, which in turn improves endurance and increases productivity.
摘要翻译： 本发明公开了一种具有改进结构的压制模具冷却装置，其能够减缓在用于压制固化的部件的生产中的钢板毛坯的压制过程期间的修剪切割的冷却速率。 本发明的加压硫化模具冷却装置的特征在于，具备：加压硫化模具，其具有上模和下模，在上模和下模的内部分别具有冷却水供给部，该冷却水供给部用于通过上下压制成形钢板毛坯 抚摸着; 以及设置在接触面之间的冷却水温度调节装置，所述接触面分别形成在上下模具中的冷却水供应部分与钢板毛坯之间，以调节输送到钢板的冷却水的温度 空白。 因此，本发明的优点在于，可以延迟从上模和下模的冷却水供应部分传递的冷却速率，以防止切边淬火并因此转变成具有高硬度的马氏体组织， 修剪过程中修剪模具上的磨损可能会减少，这反过来会提高耐力并提高生产率。

摘要： A heating furnace for a press hardening process comprises: a cylindrical heating furnace main body in which an inlet for receiving a blank steel plate from a winding coil and an outlet for discharging the blank steel plate are respectively placed on the upper and lower portions thereof and a space capable of conveying the blank steel plate is prepared therein, a conveyor which is spirally arranged in the inner circumference of the heating furnace main body in order to successively convey the blank steel plate from the upper inlet to the lower outlet, and a clamping unit which is prepared in one side of the conveyor to selectively clamp the blank steel plate. According to the present invention, the length and space occupied by the facility are farther reduced than a linear heating furnace system so the available area of a plant can be increased. There is a useful effect that product quality is improved through uniform texture variation as a result of uniformly heating the entire region of the blank steel plate being conveyed during heating. In addition, the heating time for the blank steel plate being conveyed can be shortened by increasing the heated region and in that way, productivity is improved.
