It is also opposite on outer bush to be equipped at least two screw holes；
Locknut is provided with into core bore at center before guide sleeve, and locknut is equipped with the screw thread cooperated with outer bush before guide sleeve；
Locknut offers a matching hole at center after guide sleeve, and locknut is equipped with the screw thread cooperated with outer bush after guide sleeve；
One end of interior guide sleeve offers threaded hole, and the outside wall surface of the other end is equipped with screw thread；
Die cavity nut is threadedly engaged with interior guide sleeve；
Inner core die head includes tapered portion, threaded portion, and tapered portion is coaxially concentric with threaded portion, and inner core die head is offered along axis
One goes out core perforation, and the outside wall surface of threaded portion is equipped with screw thread, and threaded portion connect locking with the threaded hole on interior guide sleeve by screw thread and matches
It closes.
Further, the screw for extending radially into outer catheter, interior guide sleeve and spiral shell are installed at the screw hole on outer catheter
Silk contradicts cooperation, guarantees the aperture for making inner core die head and the aperture of outer diameter mould in same axis and then the matching relationship with screw
On line.
The invention also discloses the rubber roll forming process based on the device, specifically includes the following steps:
Step 1: selecting matched inner core die head according to the diameter of rubber roller core, and selected inner core die head is screwed to interior lead
It puts on；
Step 2: cavity length position corresponding to sizing material pressure is determined according to sizing material and adhesive type, specifically
It is that die cavity nut is fastened on the corresponding position of interior guide sleeve for inner core die head of working good.
Step 3: the interior guide sleeve and outer bush that assemble are installed together, and are first put into the interior guide sleeve assembled outer
In guide sleeve, with nut-locking outer bush before guide sleeve, and with screw by the interior guide sleeve assembled adjustment, the center fixed to outer bush
Locknut fixation after outer diameter mould, guide sleeve is then tightly locked on outer bush by position；
Step 4: the connection nozzle on outer bush is connected with the discharge port of extruder, starts injecting glue after the completion of connection, together
When, rubber roller core is inserted into interior guide sleeve from the matching hole of locknut before guide sleeve and is stretched out from the core perforation that goes out of inner core die head；
Step 5: the rubber roller for being wrapped by sizing material is molded into from outer diameter press out after, length finer wire as needed will be extra
Sizing material excision.
Structure of the invention rationally, simple process, do not influenced in process of production by rubber roller length, the diameter of rubber roller roller core
It is adjusted by inner core die head, outer diameter, that is, encapsulated thickness of rubber roller is controlled by outer diameter die sleeve, regulates and controls sizing material by die cavity nut
Pressure, can be adapted to the molding of different size model rubber roller simultaneously, forming process streamlined, improve production efficiency and primary
Rubber roller ratio of briquetting reduces the post-processing stock removal of rubber roller, improves the utilization rate of sizing material, simultaneously because technological equipment quantity
Greatly reduce, convenient management reduces production cost, also lays a good foundation for the molding later process of rubber roller.
