Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting machines, in particular to a press-fitting machine with an overpressure warning function. Background Art

[0002] A press, also known as a press, is a mechanical device that uses the principles of compression and force. Its main purpose is to compress gas or liquid into a high-pressure state. During operation, the hydraulic pump transmits the fluid pressure to the piston of the pressure cylinder to drive the compressed object and complete the pressing process. Presses are widely used in industry.

[0003] When a press machine is pressing a workpiece, excessive pressure may sometimes occur, which may damage the workpiece. To address this defect, technical personnel in this field have developed some press machines equipped with alarms. By setting some sensors on the workbench, the output end of the press machine will contact the sensor during press loading, thereby detecting the pressure. When the pressure value is too large, an early warning alarm will be issued. However, since the sensors on the existing workbenches are all fixed tooling, they can only provide processing early warnings for workpieces of a single height. When the workpiece exceeds or is lower than the height of the workbench sensor, the sensor cannot accurately detect the pressure of the press, thereby reducing its practicality. To this end, we propose a press machine with an over-pressure early warning function to solve the above problems that may arise. Utility Model Content
