Description

Technical Field

[0001] The utility model belongs to the technical field of friction presses, and in particular relates to an adjustable friction press. Background Art

[0002] A friction press is a screw press that uses friction drive. It utilizes the contact transmission between the flywheel and the friction disc and works on the principle of relative motion between the screw and the nut. The basic parts are composed of a flywheel, a screw, a nut, a slider and a machine body. The motor directly drives the device to accelerate the flywheel to accumulate energy. At the same time, the spiral pair converts the rotational motion of the flywheel into the upward and downward linear motion of the pressing block to press the workpiece. It is widely used in stamping workshops, forging workshops and die forging workshops in industries such as machinery manufacturing, automobiles, tractors and aviation.

[0003] For example, Chinese Patent Publication No. CN117103747A discloses a friction press comprising a support plate, a support column, a motor, a first friction disc, a flywheel, a first screw, a threaded sleeve, a forging hammer, and a forging seat. The support column is symmetrically fixed to the lower surface of the support plate. A first fixed plate and a second fixed plate are fixed to opposite sides of the upper surface of the support plate. First rotating shafts are rotatably mounted on opposite sides of the first and second fixed plates. Opposite ends of the two first rotating shafts are fixedly connected to the first friction disc. The motor is fixedly mounted on a side of the first fixed plate, and the output end of the motor is fixedly connected to one end of the first rotating shaft. The first screw is vertically rotatably mounted in the middle of the support plate, and the lower end of the first screw is threadedly connected to the threaded sleeve. This friction press increases the contact area between the friction disc and the flywheel, preventing slippage between the friction disc and the flywheel. Furthermore, the forging hammer can be disassembled and replaced, thereby improving processing efficiency.

[0004] The above application still has the problem that the workbench is difficult to move and adjust, making it inconvenient to pick up and place the workpiece. At the same time, a person needs to reach into the bottom of the lower pressing block to operate, which affects the safety of the device.

[0005] Therefore, an adjustable friction press is needed to solve the problems raised in the above background technology. Utility Model Content
