Description
Technical field
The present invention relates to the plant equipment in a kind of plastic processing, particularly to a kind of double-screw extruder screw screw thread unit
The provision for disengagement of part.
Background technology
Double screw extruder is widely used in polymer blending modification, and the screw rod of double screw extruder uses building block system to set
Meter: various screwing elements are installed on two screw mandrels by spline.According to product and the difference of technique, often need to be by screw rod
Transfer to from extruder and screwing element is disassembled from mandrel, then screwing element cleared up and reconfigure.
At present, the method for conventional dismounting screwing element is: 1) workman use the instruments such as copper rod to beat screwing element so that
It removes from mandrel；2) if 1) described method is invalid, then use firelock that screwing element first carries out local and heat, then pass through
Manpower taps dismounting.The shortcoming of said method is: 1) due to the helical shape of screwing element uniqueness so that workman taps screw thread
Effective stress point cannot be found during element, cause efficiency the lowest；2) also due to the geometry of screwing element, screw thread is caused
The spiral shell rib of element is easy to when tapping damage；3) use the mode burnt to easily cause hot-spot, thus cause screw thread unit
Part and the deformation of mandrel；4) mode burnt is used to there is potential safety hazard.

According to above technical problem, the present invention provides a kind of double-screw extruder screw screwing element provision for disengagement, specifically
Technical scheme is as follows:
A kind of screw flight element provision for disengagement, including screw rod cutting ferrule, clamping device and driving means, screw rod cutting ferrule is used for
The fixing screw rod with screwing element to be removed, screw rod cutting ferrule detachably lock onto in clamping device, and driving means drives clamping
Device dismantles screwing element relative to screw motion.
Preferably, described screw rod cutting ferrule and clamping device are provided with two groups, and described driving means is synchronous drive device, with
Step drives two stack clamping device move toward one another to dismantle screwing element.
Preferably, described screw rod cutting ferrule is aluminum cutting ferrule, and screw rod cutting ferrule is divided into upper and lower two parts.
Preferably, described clamping device includes that base and pressed seat, screw rod cutting ferrule lock onto between base and pressed seat.
Preferably, described driving means is hydraulic jack.
Preferably, the line slideway for guiding clamping device to move and lead are also included.

Detailed description of the invention
The present invention is described in detail with being embodied as example below in conjunction with the accompanying drawings, but embodiments of the present invention do not limit
In this.
See shown in Fig. 1-3, a kind of screw flight element provision for disengagement, fill including screw rod cutting ferrule 7, clamping device and driving
Putting 5, screw rod cutting ferrule 7 is for the fixing screw rod 3 with screwing element to be removed, and screw rod cutting ferrule 7 detachably lock onto clamping device
In, driving means 5 drives clamping device to move relative to screw rod 3 and dismantle screwing element.Described screw rod cutting ferrule 7 and clamping device
Being provided with two groups, described driving means 5 is synchronous drive device, synchronizes to drive two stack clamping device move toward one another and dismantle screw thread
Element.Described screw rod cutting ferrule 7 is aluminum cutting ferrule, and screw rod cutting ferrule 7 is divided into upper and lower two parts.Described clamping device includes base 6 He
Pressed seat 8, screw rod cutting ferrule 7 lock onto between base 6 and pressed seat 8.Described driving means 5 is hydraulic jack.Also include for
Guide line slideway 1 and the lead 2 of clamping device motion.Also include for the screw support 9 at two ends studdle 3.Institute
State screw rod cutting ferrule 7 and there is the aperture being suitable for 20-160mm diameter thread element.Also including moving frame 4, clamping device passes through
Line slideway 1 and lead 2 are arranged on moving frame 4, also include the screw support 9 being arranged on moving frame 4.
Fig. 1 show the schematic diagram of the screwing element provision for disengagement dismantling screw of the present invention.First locking nut is unclamped,
Open pressed seat 8；Then screw rod cutting ferrule 7 top half is removed；In screw rod 3 embedding device will extracted from extruder again, its
Two ends are supported by screw support 9, and mid portion is then supported by the latter half of screw rod cutting ferrule 7；Put into screw rod cutting ferrule 7 afterwards
Top half, close pressed seat 8, tightens locking nut and is fixed screw rod；Then pulling down screw rod head, subsequent start-up synchronizes liquid
Compressing cylinder drives clamping device, and then automatically releases screwing element, completes the dismantlement work of screwing element.As it is shown in figure 1, this dress
Put and include moving frame 4, frame has clamping device, be installed on clamping device screw rod cutting ferrule 7, be used for driving clamping device to move
Synchronous hydraulic oil cylinder, for supporting the screw support 9 of screw rod.
As in figure 2 it is shown, the present invention uses aluminum cutting ferrule to fix screw rod, described aluminum cutting ferrule is divided into upper and lower two parts.Tool
For body, in the middle of upper and lower two parts, all perforates are with standing screw.According to the difference of screw diameter, the diameter in hole changes the most therewith.
As it is shown on figure 3, the present invention uses synchronous hydraulic oil cylinder to drive clamping device to carry out the automatic dismantling of screwing element.
Synchronous hydraulic oil cylinder can use two or four to be arranged symmetrically with, and uses two symmetrical cloth of hydraulic jack in the present embodiment
Put.
As it is shown on figure 3, the present invention uses line slideway 1 and lead 2 to guide the motion of clamping device, it is ensured that clamping device
Motion consistent with screw axis, it is to avoid in the unloading process of screwing element, screwing element and mandrel are caused damage, certainly
Alternate manner can also be used to guide the motion of clamping device.
As it is shown in figure 1, the present invention uses screw support 9 at the two ends studdle of screw rod, it is to avoid dismantle at screwing element
During screw rod deform and cause the damage of screwing element or screw mandrel.Because its length of the screw rod that industry commonly uses at present
Spending the most long, under vacant state, screw rod can produce certain deformation, especially for major diameter due to the effect of gravity
For screw rod.The position that screw support 9 contacts with screw rod uses softer metal material and coordinates the diameter of screw rod.
