specific Embodiment 2
[0049] The difference between this embodiment and Embodiment 1 is that the crossties 19 of the present embodiment are trapezoidal bodies, and the side where the inclined chute 18 is installed is a slope perpendicular to the bottom surface, and the inclined chute 18 has no slope difference, and the crossties 19 enter the die One end in the chamber 3 starts to have a cross-section gradually increasing from small to the other end, and the rest are the same as in Embodiment 1.
specific Embodiment 3
[0051] The difference between this embodiment and embodiment 1 is that the slanted chute 18 of the present embodiment is deep, from the end where the sleeper 19 enters the mold cavity 3 to the other end from deep to shallow, and all the others are the same as in embodiment 1.

A pressing preventing mechanism comprises a punch and a sleeper. A control system is used for driving an air cylinder to do the piston motion so that the sleeper can get into or get out of a die cavity, meanwhile, dual protection is achieved through the front-back movement of a photoelectric stop sheet, and the situation that the punch abnormally runs in the adjusting and maintaining process, andthe double hands of a worker are bruised is prevented. Compared with a traditional pressing preventing manner, operation is easier, and by utilization of the linear reciprocated motion of the air cylinder, automatic stretching-in and retreating of the sleeper are achieved; by utilization of the interlocking principle, equipment control and sleeper control are related, the fool-proofing design effect is achieved, and accidents caused by human errors are avoided; and by utilization of the photoelectric stop sheet and the sleeper, safety dual security is achieved, mechanical and electronic dual protection is achieved, and more safety is achieved.
Description
technical field [0001] The invention belongs to the field of sheet metal molds, and mainly relates to an anti-pressure mechanism in the debugging and maintenance process of sheet metal molds. [0002] technical background [0003] In the current mass stamping production and processing, sheet metal molds are the most important processing and forming equipment, and are widely used in the manufacturing fields of automobiles and home appliances. In the stamping production process of sheet metal molds, various abnormalities often occur, which lead to production interruption, requiring shutdown for maintenance and debugging; and during maintenance and debugging, safety accidents such as molds and personnel crushing often occur. [0004] Therefore, how to effectively avoid crushing accidents is very important for the operators and the mold itself. In the existing industrial production, the anti-pressure methods of sheet metal stamping production are: [0005] Option 1: The operato...
