Problems solved by technology

Since the mechanical type such as the crank press does not allow the operator to stand within a certain range when it is working, when the crank press is overloaded and stuck, the operator sometimes will not find the fault in a short time, resulting in The drive motor is overloaded and burned
[0003] At the same time, the feeding mechanism of the existing mechanical press is generally independent, so when the upper mold is overloaded and stuck, the feeding mechanism is still in the feeding state, resulting in overloading and burning of the feeding mechanism

Abstract

The application discloses an overload protection system for a crank press, which includes a housing, a transmission mechanism, a stamping assembly and a drive unit. The transmission mechanism, the stamping assembly, and the drive unit are all installed in the housing. The overload protection assembly of the shaft and the crankshaft, the drive shaft and the crankshaft are installed in the housing, the first end of the drive shaft is connected to the transmission mechanism, so that the transmission mechanism passes the drive shaft and drives the crankshaft through the overload protection assembly, and the crankshaft is connected to the stamping assembly , Whether the overload protection component is connected to the drive shaft and the crankshaft can be realized according to the load force of the stamping component. Beneficial effects of the application: the traditional integrated drive unit is divided into two parts, the crankshaft and the drive shaft, and connected by an overload protection assembly. When the stamping assembly is overloaded, the overload protection assembly disconnects the connection between the crankshaft and the drive shaft, thereby Carry out overload protection to the driving motor on the transmission mechanism to prevent it from burning due to overload.

Description

technical field [0001] The present application relates to the field of stamping equipment, in particular to an overload protection system for a crank press. Background technique [0002] Presses are widely used in blanking, punching, forming, stretching and other processes of sheet metal. Existing presses are generally classified into hydraulic or mechanical types, and the common press in the mechanical type is the crank press. In the actual stamping process, sometimes due to the wear and tear of the equipment, the positioning of the upper mold and the lower mold is incorrect, which leads to the inability of the upper mold to stamp the plate into the lower mold, which in turn causes the upper mold to be overloaded and stuck. For hydraulic presses, when the upper mold is overloaded and stuck, the hydraulic system will release pressure to protect the press. Since the mechanical type such as the crank press does not allow the operator to stand within a certain range when it i...
