Description

A kind of extrusion sebific duct end shear

Technical field

The utility model relates to exhaust pipe for vehicle processing technique fields, more particularly, to a kind of extrusion sebific duct end shear.

Background technique

Exhaust pipe for vehicle is generally process using extrusion process, and processing step generally comprises tabletting, extrusion and vulcanization, is added The good sebific duct of work need to obtain the smooth effect in end face through cutting head process.In the prior art, cutting head mainly uses following two mode: 1) it manually cuts off, this kind cuts off technique and fall behind, and end face planarization is poor, and processing cost is high, low efficiency；2) machine is cut off. Application No. is a kind of head cutting device is disclosed in 201420106296.0 utility model patent, which includes pedestal, the bottom of at Parallel card slot is opened up on seat, card slot two sides set support rod, also set rotary cutting apparatus above card slot and support rod.The device exists In use, can then make blade be cut around sebific duct by glue pipe socket on plug, advantage is that the merging of plug is promoted Cutting accuracy, but the device do not consider how the problem of taking off on sebific duct head from plug.

Summary of the invention

The purpose of the utility model is to overcome disadvantages existing in the prior art, provide a kind of extrusion sebific duct end shear, The end shear sets demolded parts, will cut off and take off, the technical solution adopted is that: a kind of extrusion sebific duct end shear, including rack, Sebific duct clamping part is installed in the rack and sebific duct cuts off part, sebific duct cutting head part is arranged on sliding platform, institute Stating sebific duct cutting head part includes rotating blade, it is characterised in that: the end shear further includes support core part, the support core part packet The attachment base being mounted on sliding platform is included, support core driving cylinder, the piston of the support core driving cylinder are set on the attachment base Bar is connect with support core, and the support core sets the inflation through-hole connecting with air pump, and the support core outer diameter is matched with sebific duct internal diameter, The support core guide end face sebific duct, the support core part further include stripper sleeve, and support core passes through stripper sleeve, goes back in the stripper sleeve If demolded parts, the end of the demolded parts protrudes into stripper sleeve and has a gap between support core outer surface, and the gap is smaller In the wall thickness of core pipe.

The power resources of rotating blade further include the deceleration electricity being mounted on attachment base in motor, i.e., the described cutting head part Machine, the power output of the geared motor output shaft to rotating blade.

For the relative position between adjustment dise knife and sebific duct, the sliding platform includes the sliding sleeve positioned at bottom, the cunning The upper surface for moving platform sets the line slide rail cooperated with sliding sleeve, and the piston rod of sliding driving cylinder connect with sliding platform, passes through Drive cylinder driving sliding platform mobile.

The sebific duct clamping part of this end shear includes the tooling of fixed sebific duct, further includes intermediate aperture, wears for support core The collet crossed, the other side of the collet are sebific duct cutting head part and support core part.

The movement of blade includes moving up and down for rotation and opposite sebific duct, realizes the mobile structure of blade are as follows: the sebific duct Cutting head part further includes knife rest cylinder, and the piston rod of the knife rest cylinder connects knife rest, and the rotating blade is mounted in cutterhead, The cutterhead is mounted on knife rest.

Corresponding to rotating blade, processed on the outer surface of the support core fluted.When groove provides blade cutting sebific duct Required droping space.

The utility model has the beneficial effects that: support core is placed in sebific duct by this end shear in cutting head, sebific duct is avoided The problem of end face generated in cutting is irregular, hair stubble, effectively improves the machining accuracy of cutting head；The blade of this end shear is in gas Cylinder moves up and down under driving, and the cutting head of sebific duct can be completed in time processing, avoids and occurs after cutting repeatedly in the prior art Line layer hair stubble problem；The cutting head surfacing of this cutting head machining, cutting head speed is fast, and saves artificial.
