Description

Technical Field

[0001] The utility model relates to the technical field of profile processing, in particular to a counterbore press for sheet metal parts. Background Art

[0002] In the sheet metal processing industry, the counterbore process is one of the indispensable steps. Especially when manufacturing sheet metal parts that require precise positioning and high-quality processing, it involves forming holes with a certain depth and diameter on the sheet metal parts to meet the requirements of subsequent assembly or connection. The traditional counterbore process often relies on manual operation or simple mechanical devices. These traditional methods are not only cumbersome and inefficient in operation, but also often result in large errors due to human factors, affecting the overall quality and accuracy of the products.

[0003] Specifically, traditional counterbore equipment usually lacks precise control mechanisms, resulting in the inability to accurately control the depth, diameter, and position of the counterbore during the processing. In addition, due to the unpredictability and inconsistency of manual operation, it is difficult to maintain a constant force and speed during the counterbore process, further increasing the possibility of errors. These problems not only affect the appearance and performance of the products, but may also cause difficulties in the subsequent assembly process, and even affect the service life of the entire product.

[0004] Although there are already some automated counterbore equipment on the market, these equipment are often costly. For general sheet metal processing enterprises, purchasing and maintaining these equipment is a significant expense. Therefore, many enterprises still adopt traditional counterbore methods and face problems such as cumbersome operation, low efficiency, and large errors.

[0005] In view of the above problems, the utility model proposes a new type of counterbore press for sheet metal parts. Summary of the Utility Model

[0035] Operation: When operating a countersunk press, the operator needs to be familiar with the equipment's operation and control buttons to ensure safe starting and stopping of the equipment, as well as adjusting processing parameters such as screw descent speed and mold closing force.

[0036] Usage and steps: When using the countersinking press, the operator first places the metal workpiece on the roller rack and determines the countersinking position of the metal workpiece by moving the material rack cart. Then, by starting the worm screw elevator, the screw of the screw elevator is driven to descend at a constant speed. When the screw descends, the upper and lower parts of the mold gradually approach each other until they are closed. During the mold closing process, the metal workpiece is clamped between the molds, compacted and countersunk. After the processing is completed, the screw is stopped from descending, the mold is opened, and the processed product is taken out.

[0037] These steps and methods need to be adjusted and implemented according to the operating manual to ensure the normal operation and safe operation of the equipment.
