Problems solved by technology
[0002] When punching thin material blanking parts, steel strip punching dies are usually used. When the shape of the punched workpiece is slender, if a conventional steel strip punching die is used, the inner template of the punch is also very slender, so its strength is very high. weak
And when the distance between the center hole and the outer shape of the blanking workpiece is small, the strength of the inner template between the punching die edge and the blanking punch edge of the conventional composite steel strip punching die is also very weak.

The invention relates to a novel steel belt punching die which comprises an upper die body and a lower die body. The upper die body comprises an upper die seat, a punching male die, a steel belt female die and an outer die plate; the punching male die and the steel belt female die are fixed to the lower end surface of the upper die seat, and a reinforcing pressing plate is arranged on the outer side of the upper die seat; a second elastic jacking device is annularly arranged outside the punching male die, and a first elastic jacking device is annularly arranged inside the steel belt female die; the lower die body comprises a lower die seat, and a cushion block is arranged on the lower die seat; a lower die plate is arranged on the cushion block, and a base plate is arranged on the lower die plate; an elastic unloading device and a punch-die are arranged on the base plate, and the elastic unloading device penetrates through the punch-die and is connected with the base plate; and a discharging hole is formed in the cushion block, and the lower die plate, the base plate and the punch-die are connected through screw rods. The novel steel belt punching die has the characteristics of being simple in structure, low in manufacturing cost and convenient to operate and implement.
Description
technical field [0001] The invention belongs to the technical field of punching dies, in particular to a novel steel strip punching die. Background technique [0002] When punching thin material blanking parts, steel strip punching dies are usually used. When the shape of the punched workpiece is slender, if a conventional steel strip punching die is used, the inner template of the punch is also very slender, so its strength is very high. weak. And when the distance between the central hole and the profile of the blanking workpiece is small, the strength of the inner template between the punching die edge and the blanking punch edge of the conventional composite steel strip punching die is also very weak. Therefore, it is necessary to develop a steel strip punching die that is suitable for punching thin and long workpieces. Contents of the invention [0003] The object of the present invention is to solve the above technical problems and provide a steel strip punching di...
