This utility model relates to the field of extrusion molding die technology, specifically a cooling mechanism for an aluminum profile extrusion molding die. It includes a die body, a connecting ring, and a cooling assembly. The die body comprises an upper die and a lower die, arranged parallel to each other. The connecting ring is connected to the lower die at the end furthest from the upper die. The cooling assembly is connected to the die body and includes a limiting ring, a cooling ring, a rotating disk, a sliding component, and a locking block. In this utility model, the cooling assembly can be directly fitted onto the die body. The rotation of the rotating disk and the movement of the sliding component in the cooling assembly cause the locking block to insert into the slot on the connecting ring, achieving quick assembly and disassembly. Simultaneously, the position of the rotating disk can be controlled after rotation, preventing accidental contact and displacement. Furthermore, the limiting ring is connected to the connecting ring, and the entire die body is surrounded by the cooling ring, preventing uneven cooling due to a small cooling area.

This utility model relates to the field of suspended heat treatment conveyor technology and discloses a cooling device for a suspended heat treatment conveyor, including a base and hooks for suspension. A cooling box is fixedly installed on the top of the base. This cooling device for a suspended heat treatment conveyor, through the setting of a control component, allows the output shaft of the motor to drive the threaded rod to rotate within the fixed frame. The moving plate can drive the fixed plate and hooks into the cooling box through the support plate and support rod. When the support block at the top of the support plate abuts against the surface of the fixed block, the support block can be moved downward under force. The fixed plate connected to the support plate surface through the support rod can drive the hook to move longitudinally. Since there are multiple sets of fixed blocks, the support blocks can abut against each other multiple times, so that the fixed plate and hooks can move longitudinally intermittently within the cooling box, making all-round contact with the cold air in each area, avoiding the fixed cooling area and causing uneven cooling.

The utility model relates to aluminium alloy extruding machine technical field, and disclose a kind of aluminium alloy extruding machine with cooling mechanism, including bottom plate, the top fixed mounting of bottom plate has fixed plate, this aluminium alloy extruding machine with cooling mechanism is rotated when the fan blade in fan is set with control component, and rotating rod can drive cam to rotate on the surface of support, when cam rotates, cam will be in contact with the section of slide bar, when the section of slide bar is contacted, slide bar can be forced to move horizontally in cooling box, when slide bar moves, the moving plate fixed on the surface of slide bar can drive movable plate to move horizontally synchronously, since slide bar is intermittently contacted, therefore, moving plate and movable plate can be intermittently opened and closed in front of cooling box, to continuously push airflow to be stirred, reach the purpose that the airflow around aluminium billet is continuously heat-exchanged, avoid the situation that cooling is uneven due to airflow direction is fixed.

The application discloses a kind of based on low temperature embrittlement cooperates prefabricated mark guide plate stamping equipment, including base and the shelf plate of being movably arranged on base, the holding module for being clamped and positioning outside the processing area of tensioning the plate to be processed of outside the plate to be processed is arranged between the base and shelf plate, and the groove prefabricated module for processing V-shaped guide groove to outside the plate to be processed preset fracture zone, the low-temperature cooling module for the plate after being processed by groove prefabricated module is arranged on the side of base, to reduce the temperature of plate and maintain low-temperature atmosphere by being used for rapid cooling, and the control cabinet for being respectively communicated connection control with holding module, groove prefabricated module and low-temperature cooling module.The application solves the problem that traditional stamping process handles high-strength alloy plate and the outer ring component of difficult deformation material, because prefabricated mark processing, low-temperature treatment and stamping forming link discrete layout lead to parameter matching, low-temperature embrittlement uncontrollable, difficult to realize the problem of accurate control of fracture surface quality.

The application relates to the technical field of cold drill shafts, in particular to an internal cooling drill shaft device based on a turning-milling-drilling composite machining center, which comprises a machining equipment body, the machining equipment body is composed of a machine base, two linear modules one, two linear modules two, a machining table and a machine frame.
