The invention relates to a safety protection device for a small-sized forging bed, and effectively solves the problem that in the prior art, the small-sized forging bed lacks clamping equipment and is equipped with seriously imperfect protection equipment. According to the technical scheme, the safety protection device comprises a ring-shaped sleeve, wherein a plurality of stepped through holes are uniformly distributed on the circumference of the ring-shaped sleeve; a pressure rod is mounted in each stepped through hole; each pressure rod comprises an outer sleeve rod and an inner sleeve rod; a blind hole is formed in one end of each outer sleeve rod, and the corresponding inner sleeve rod is slidably mounted in the blind hole and can be prevented from slipping; a strong pressure spring is mounted in each blind hole; an elastic pressure belt and a turning roll are mounted outside the ring-shaped sleeve; the turning roll is positioned below the ring-shaped sleeve; one end of the elastic pressure belt is fixed on the outer wall of the ring-shaped sleeve; the other end of the elastic pressure belt turns around, and penetrates through the gap between the turning roll and the ring-shaped sleeve; a tension rope is connected with the free end of the elastic pressure belt; a first pulley, a second pulley and a third pulley are mounted under the elastic pressure belt; and the tension rope is wound around the three pulleys in sequence. The safety protection device provided by the invention is simple and ingenious in structure, economic and practical, and convenient and rapid to use.
Description
technical field [0001] The invention relates to the field of safety protection, in particular to a safety protection device for a small forging machine. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging can eliminate defects such as as-cast porosity produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. [0003] Most of the mechanical equipment used for forging is a forging machine. Large-scale forging machines generally have professional clamping equipment to clamp the workpiece to ensure the accuracy and safety of the workpiece during forging, and the protection facilities are also very complete; however,...
