Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts production, specifically to a new energy automobile motor cover covers aluminum foil hot press forming device. BACKGROUND

[0002] The automobile motor cover covers aluminum foil hot press forming device is a process equipment specially used for automobile motor cover manufacturing, which is mainly used for processing aluminum foil materials into parts meeting the shape and size requirements of automobile motor covers through hot press forming. During use, the aluminum foil material is placed in the forming cavity of the forming die and heated by the heating system. During the heating process, the control system monitors the temperature of the aluminum foil material in real time and adjusts it according to the preset temperature curve to ensure that the aluminum foil material is uniformly heated and reaches a thermoplastic state. When the aluminum foil material reaches the thermoplastic state, the pressure system starts to work and applies pressure to the aluminum foil material, which adheres to the forming cavity of the forming die to form the required shape.

[0003] For example, the Chinese patent "A new energy automobile motor cover covers aluminum foil hot press forming method and device" with the announcement number CN117863565A includes a bracket, an upper profiling bracket arranged on the bracket, a pre-pressing forming surface matched with the profile shape of the position needing to be covered with aluminum foil arranged on the upper surface of the upper profiling bracket, left and right profiling surfaces matched with the left and right inner surfaces of the upper part of the new energy automobile motor cover arranged on the left and right surfaces of the upper profiling bracket, and a cooling water pipe arranged in the upper profiling bracket; a lower profiling bracket arranged on the bracket below the upper profiling bracket, a lower profiling surface matched with the inner surface of the lower part of the new energy automobile motor cover arranged on the lower profiling bracket; a motor cover fixing mechanism arranged on the bracket for pressing the new energy automobile motor cover on the upper and lower profiling brackets; and a pre-pressing driving mechanism arranged on the bracket and connected with the hot press die head at the output end for driving the hot press die head to pre-press the aluminum foil.

[0004] Although the above-mentioned prior art can realize the hot press forming of aluminum foil, in actual use, on the one hand, the finished product is not taken out quickly enough, usually after the hot press of the aluminum foil is completed, the finished product is taken out from the forming cavity after the fixed mold is naturally cooled, which affects the production efficiency of the finished product, on the other hand, the clamping mechanism is not convenient to adjust, usually different finished products are needed for different vehicle models, which leads to the need to replace different fixed molds and movable molds, and the overall fixing structure of the fixed mold needs to be disassembled and assembled during the replacement of the fixed mold, thereby increasing the workload of the operators, therefore it does not meet the existing needs, for this we put forward a new energy automobile motor cover covers aluminum foil hot press forming device. UTILITY MODEL CONTENTS

[0005] The utility model discloses a new energy automobile motor cover covers aluminum foil hot press forming device to solve the problem of not enough quick of finished product's taking and not enough convenient of clamping mechanism adjustment in the background art.

[0006] In order to realize the above-mentioned purpose, the utility model provides the following technical scheme: a new energy automobile motor cover covers aluminum foil hot press forming device, including frame, the frame is provided with two, the upper end height of frame is provided with operation table, the top of operation table middle position is provided with hot press station, the inside of hot press station is provided with a plurality of air holes, and the air hole is through -type structure, and the air hole is equidistance distribution, a plurality of radiating fins are fixedly arranged at the lower end between the air holes of hot press station, and the radiating fins are equidistance distribution.

[0009] Preferably, a rubber pad is fixedly arranged on one side of the telescopic end of the second hydraulic telescopic device, and a fixed mold is arranged at the central position of the upper end of the hot press station, and the rubber pad is in contact with the outer wall of the fixed mold.

[0010] Preferably, seven heating wires are fixedly arranged in the fixed mold, and the heating wires are equidistantly distributed.

[0011] Preferably, dampers are fixedly arranged at the four corner positions of the lower end of the hot press station, the lower end of the damper is fixedly connected with the operation table, and a supporting spring is fixedly arranged between the telescopic end and the fixed end of the damper.

[0012] Preferably, first hydraulic telescopic devices are fixedly arranged at the four corner positions of the upper end of the operation table, an installation plate is fixedly arranged at the upper end of the telescopic end of the first hydraulic telescopic device, four connecting rods are fixedly arranged at the lower end of the installation plate, the connecting rods are equidistantly distributed, a movable mold is arranged at the lower end of the connecting rod, the connecting rod and the movable mold are fixedly connected through bolts, and the movable mold corresponds to the fixed mold in position.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] 1. The utility model can accelerate the dissipation of heat on the fixed mold through the ventilation cavity and the heat dissipation fins. When the hot pressing is completed, the drive motor is turned on, and the output shaft of the drive motor drives the fan blades to rotate. At this time, the air near the fan blades forms a negative pressure and drives the outside air to enter the ventilation cavity at an accelerated speed. The generated airflow is blown toward the lower end of the hot pressing table under the action of the fan blades. Usually in the hot pressing project, the fixed mold and the hot pressing table are both made of metal. At this time, the heat on the fixed mold is transferred to the hot pressing table, and the heat on the hot pressing table is transferred to the metal heat dissipation fins. At the same time, the air flow blows into the heat dissipation fins and air holes, so that the heat on the hot pressing table is quickly dissipated, and the cooling rate of the fixed mold is accelerated, thereby improving the efficiency of aluminum foil hot pressing.

[0015] 2. The utility model can clamp and fix fixed molds of different sizes and shapes through the second hydraulic telescopic device and the rubber pad. When the fixed mold is replaced, the second hydraulic telescopic device is turned on, so that the telescopic end of the second hydraulic telescopic device is contracted and drives the rubber pad to move until the rubber pad is separated from the outer wall of the fixed mold. At this time, the old fixed mold is taken out from the hot pressing table, and the new fixed mold is placed in the center position of the hot pressing table. At this time, the second hydraulic telescopic device is synchronously turned on, so that the telescopic end of the second hydraulic telescopic device is extended and drives the rubber pad close to the outer wall of the new fixed mold until the rubber pad contacts the outer wall of the fixed mold and causes extrusion, completing the replacement of the fixed mold, thereby improving the adaptability of the clamping mechanism to fixed molds of different sizes.

[0016] 3. The utility model can provide a buffer for the hot pressing table through the damper and the support spring. When the hot pressing operation is performed, the aluminum foil has been placed in the forming cavity of the fixed mold. At this time, the first hydraulic telescopic device is turned on to make the telescopic end of the first hydraulic telescopic device contract and drive the mounting plate and the movable mold to move downward together until the movable mold enters the forming cavity of the fixed mold and squeezes the aluminum foil. At this time, the movable mold continues to move downward until the movable mold squeezes the fixed mold. At this time, the damper and the support spring at the lower end of the hot pressing table are deformed after being squeezed. The squeezing on the hot pressing table is absorbed by the deformation of the damper and the support spring, thereby avoiding the hot pressing table from directly contacting the operating table and causing damage, thereby extending the service life of the hot pressing table.
