Abstract

The invention provides a lead delay element rotary cutter which comprises a rotary cutting assembly, a feeding detection mechanism, a horizontal and vertical straightening mechanism, a tensioning device, a linear (or disc type) wire inlet platform and an industrial personal computer which are all arranged on a worktable. A lead delay cord is driven by the feeding detection mechanism which is driven by a stepping motor and straightened by the straightening mechanism, passes a hollow lead delay cord fixing shaft of the rotary cutting assembly and then butts against the rotary cutting position, a high-accuracy coder detects required cutting length information and then sends instructions to rotary cutting blades, a rotary cutting cylinder arranged on the rotary cutting assembly pushes the rotary cutting blades to radially move towards the axis of the lead delay cord fixing shaft to cut off the lead delay cord, and rotary cutting is completed. The radially symmetrically arranged rotary cutting blades and rotary cutting riding wheels simultaneously apply force in the axis direction on the circumference of the lead delay cord, radial thrust in all directions is offset, the section of a cut lead delay element is level and does not deform, U-shaped section cannot be formed, and product scraps are few.

Description

technical field [0001] The invention relates to the field of detonator production, in particular to a lead extension rotary cutting machine. Background technique [0002] With the widespread use of industrial detonators in engineering blasting and directional blasting, the delay accuracy of industrial detonators has become increasingly demanding. The lead delay body is one of the main components of the industrial detonator. Its function is to receive the flame of the gunpowder head, and after delayed combustion, it is transmitted to the primer to achieve the purpose of delay; The relationship between seconds is very close, which directly affects the quality of blasting and the safety of use. [0003] At present, the extension body is formed by cutting the lead extension cable with a length of several meters to tens of meters that has been manufactured according to the process requirements into small sections of specified length, because the length of the extension body is d...
