Technical Field
[0001] The utility model relates to the technical field of presses, in particular to a manual press. Background Art
[0002] A manual press is a mechanical device used to process metal, plastic or other materials. It is usually controlled by a handle or lever and uses manpower to apply pressure to process the material into the desired shape or size. Manual presses are usually used for processing processes such as stamping, bending, die-casting and stretching. They can be used to make metal parts, punch holes and press plastic products, etc.
[0003] Manual presses are usually used to press some small precision parts, but the pressure of existing manual presses is fixed and cannot be adjusted. For some small precision parts that are easy to break, excessive pressure at one time can easily lead to the scrapping of parts. Therefore, we propose a manual press. Utility Model Content

[0006] By adopting the above technical scheme, the parts to be pressed are placed on the lower die base, the pressing structure is used to press the parts, the limiting component limits the pressing distance of the pressing structure, and the adjusting component changes the height of the limiting component, thereby adjusting the distance from the pressing structure to the limiting component. The pressure of the pressing structure can be changed according to the characteristics of the processed parts to avoid the scrapping of parts due to excessive pressure. The stabilizing component plays a better supporting role for the limiting component to ensure that the pressing structure can be pressed more stably when the pressing structure is in close contact with the limiting component.
[0007] The utility model is further configured as follows: the downward pressing structure includes a pressing rod hinged to the mounting beam, a pressing handle connected to the pressing rod, a sliding rod affixed to the bottom of the pressing rod and penetrating the upper guide plate and extending to the bottom of the lower guide plate, a pressing head connected to the bottom of the sliding rod, a retaining ring installed on the outside of the sliding rod, and a return spring sleeved on the outside of the sliding rod and connected between the retaining ring and the lower guide plate.
[0008] By adopting the above technical solution, the pressing handle is held to drive the pressing rod to move downward, and the sliding rod then drives the pressing head to move downward to press the parts on the lower die seat. At this time, the retaining ring moves the sliding rod downward to compress the return spring between the retaining ring and the lower guide plate. After the parts are pressed, the pressing handle is released, and the return spring resets the retaining ring to drive the sliding rod to move upward, so that the next pressing work can be carried out again.

[0012] The utility model is further configured as follows: the supporting connecting rod is movably connected to the mounting groove and the inner wall of the mounting groove and is fixedly connected to the bottom of the limiting plate.
[0013] By adopting the above technical solution, when the adjustment component changes the horizontal height of the limiting plate, the support link is adjusted up and down synchronously with the limiting plate under the support of the support spring, supporting the limiting plate, so that the limiting plate can limit the pressing handle more stably.
[0014] The utility model is further configured as follows: the adjustment component includes a motor installed inside the limiting groove, a bidirectional screw connected to the motor output shaft and rotatably connected to the inner wall of the limiting groove, two threaded sliders threadedly connected to the outside of the bidirectional screw and movably connected to the bottom wall of the limiting groove, and a hinged rod hinged to the threaded sliders, and the hinged rod is hinged to the bottom of the movable vertical rod.
[0015] The utility model is further configured as follows: the exterior of the bidirectional screw is provided with two sections of threads with opposite screw directions.
[0016] By adopting the above technical solution, the motor is started to drive the bidirectional screw to rotate, and the two threaded sliders are respectively connected to the two sections of threads with opposite screw directions, so that the two threaded sliders can approach or separate synchronously. When the threaded sliders approach or separate, the hinged rod is used to push the moving vertical rod up and down, thereby changing the horizontal height of the limiting plate, thereby realizing adjustable pressure of the downward pressure structure.
[0017] The beneficial effects of the utility model are as follows: the pressing structure is used to press the spare parts, the limiting component limits the pressing distance of the pressing structure, the adjusting component changes the height of the limiting component, thereby adjusting the distance from the pressing structure to the limiting component, and the pressure of the pressing structure can be changed according to the characteristics of the processed parts to avoid the scrapping of parts due to excessive pressure, and the stabilizing component plays a better supporting role for the limiting component to ensure that the pressing structure can be pressed more stably when the pressing structure is in close contact with the limiting component.
