Technical field
The invention belongs to industrial explosive material field, particularly relate to a kind of Soft metal delay cord accurate cutting-off device for industrial detonator.
Background technology
At present, in civil explosive industry, extension rope cutting technique in soft metal falls behind, and the soft metal extension Suo Yiduan cut has horseshoe type, out-of-flatness, has a strong impact on time precision and the Fire Reliability of delay detonator.Though there being the extension rope two ends that equipment manufacturer develops to cut flat with equipment, two cuttves stress simultaneously during due to cutting extension rope, extension Suo Shouli crosses ambassador and delays the shortcomings such as rope deformation greatly, also makes powder loose, there is also the shortcoming that waste of raw materials is big simultaneously.
Summary of the invention
The present invention is directed to shortcoming of the prior art, provide a kind of compact conformation, simple to operate, use safety and stability, work efficiency is high, can effectively eliminate extension Suo Yiduan horseshoe type, irregular defect, reduce the deformation of extension rope, reduce the Soft metal delay cord accurate cutting-off device for industrial detonator of waste of raw materials.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: Commerical delay detonator extension rope precise cutting device, cutter and location bar is repaiied including what guiding stationary knife matched with dial feed dish with the guiding moving cutting tool that matches of stationary knife, dial feed dish, guiding stationary knife is provided with at least one charging hole (quantity of charging hole is, two, three or a plurality of), described moving cutting tool cutter head is positioned at charging hole outlet top, and contacts with guiding stationary knife outer wall；The outer circumference surface of described dial feed dish is provided with capaciting material groove；Described capaciting material groove notch is relative with charging hole outlet, and it is positioned on charging hole outlet extension line, described location bar is arranged on the axially extending line of capaciting material groove, described location bar stretches in capaciting material groove, location bar can enter capaciting material groove and directly contact extension bitter end face when needed, product is positioned, and finally cooperation is repaiied cutter and product one end is carried out equating；Described moving cutting tool include the first straight cutting face and and first cut sth. askew bevel, described first straight cutting face, towards the side near charging hole, contacts with charging hole place diametric plane.
As preferably, described capaciting material groove be shaped as strip；Described cutter of repairing includes the second straight cutting face and second and cuts sth. askew bevel, and described second straight cutting face, towards the side near capaciting material groove, contacts with capaciting material groove place diametric plane.
As preferably, described capaciting material groove arranges 2-18 group, and often group arranges 1-4 bar；Spaced set between two adjacent groups capaciting material groove；Described often group capaciting material groove cell body bar number is identical with the number of charging hole.
As preferably, the cross sectional shape of described capaciting material groove is arc, and its cell body diametric plane diameter is slightly larger than the internal diameter of charging hole.
This device also includes gathering sill, and the part outer circumference surface of described dial feed dish is positioned at gathering sill, and and leaves certain gap between gathering sill inwall.
The operating process of this device is as follows: first extension rope entrance charging hole carries out fixed length cutting, the extension rope cut enters capaciting material groove, dial feed disc spins, extension rope runs in gathering sill along with capaciting material groove, extension rope is made to enter interval, location, dial feed dish puts in place after stopping, location bar stretches into capaciting material groove and extension rope is positioned, behind location, extension rope is directed to groove compression, location bar return, pass through to repair the cutter extension Suo Yiduan to cutting off through moving cutting tool simultaneously and carry out plane finishing, after extension rope completes finishing.Dial feed dish continues to rotate, and the extension rope after finishing is fallen into and obtained finished product in receiver.Technique scheme is to utilize dial feed dish to complete entering groove, transport and completing the finishing of extension rope other end herein above extension rope.This device sets feed length by touch screen, motor complete the accurate feeding of fixed length.This device is by Programmable Logic Controller (being called for short PLC) and each observing and controlling element forming control system, accurately control extension rope feeding, make extension rope in the gap that dial feed dish pauses to complete the cut-out of extension rope, to enter capaciting material groove, and enter in capaciting material groove process to complete the location of extension rope, finishing at extension rope.
Due to the fact that and have employed above technical scheme that there is significant technique effect:
The present invention can keep the accurate fixed-length realizing the smooth of extension rope two ends and extension rope when existing production efficiency, reduce the deformation of extension rope, making finished product extension Suo Changdu accurate, powder is not loose, substantially increases accuracy delay time and the Fire Reliability of industrial plain detonator.
