Abstract
The utility model relates to a supporting device for screw restoration, in particular to the supporting device used for screw restoration bead weld of a plastic product extruder and an injection molding machine. The supporting device is easy to manufacture, process and operate. A rotating part enables a screw to rotate in the axial direction freely. A lifting hole can adjust the height of the supporting device. The distance between the supporting devices can be adjusted freely according to the length of the screw. The supporting device can be widely applied to actual production.
Description
Technical field
The utility model relates to the bracing or strutting arrangement that a kind of screw rod is repaired, and supports the device of use when particularly the screw rod of plastic product extruder and injection machine is repaired built-up welding.
Background technology
Screw rod belongs to very important parts in extruder and injection machine, the plasticizing of synthetic resin and the propelling of material all will rely on screw rod, screw rod produces the power of three directions when convey materials, once the external diameter of screw flight wearing and tearing, the gap of external diameter and barrel increases, after increasing to a certain degree, just can not continue to undertake the task of plasticizing and convey materials, at this moment screw rod can only be scrapped.In order to reduce the regeneration cost of screw rod, conventionally adopt " threaded block ", screw rod is divided into several sections, then with left-hand thread assembling, finds that one section has that wearing and tearing are rear gets on one section of new assembling, this method cost compare is high.
In sum, the utility model provides a kind of method that adopts screw rod soldering, and built-up welding is carried out to welding rod in the surface of screw rod wearing and tearing, needs to support, thereby design and invented the bracing or strutting arrangement that a kind of screw rod is repaired in the process of built-up welding.
Summary of the invention
The purpose of this utility model is to provide a kind of device that screw rod is carried out support rotating in the process of built-up welding, rotatable parts can make screw rod along axially rotating freely, the height of the bracing or strutting arrangement that lift span can adjusting screw(rod) be repaired, bracing or strutting arrangement that screw rod is repaired is simple, easy to operate and can be according to the distance between the length adjustment bracing or strutting arrangement of screw rod.
The bracing or strutting arrangement that screw rod is repaired, is comprised of rotatable parts, fixed bar, upper support parts, lower support parts and base; Lower support parts are arranged on base, and rotatable parts are provided with on fixed bar, and fixed bar is fixedly connected with upper support parts, and upper support parts and lower support parts are respectively equipped with lift span.The shape of base is cross, circle or square.Upper support parts and lower support parts are hollow cylindrical or hollow square.The shape of fixed bar is circular, square or triangle.Upper support parts are connected by lift span with lower support parts.In order well to play a supporting role, the bracing or strutting arrangement quantity of screw rod reparation is at least two.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment front view
Fig. 2 is the utility model embodiment left view
Fig. 3 is the utility model embodiment A-A cutaway view
In Fig. 1-3,1 is that rotatable parts, 2 are that fixed bar, 3 is that upper support parts, 4 are that lower support parts, 5 are that lift span, 6 is base.
The specific embodiment
The utility model embodiment comprises that rotatable parts 1, fixed bar 2, upper support parts 3, lower support parts 4 and base 6 form, lower support parts 4 are arranged on base 6, play the effect of support, on rotatable parts 1, be provided with on fixed bar 2, fixed bar 2 is fixedly connected with upper support parts 3.Upper support parts 3, lower support parts 4 are respectively equipped with lift span 5.The shape of base 6 is cross, circle or square, like this can be stable vertical on the ground.Upper support parts 3 and lower support parts 4 are hollow cylindrical or hollow square, can alleviate overall weight like this.The shape of fixed bar 2 is circular, square or triangle, is mainly used to rotatable parts 1 to be fixed on upper support parts 3.Upper support parts 3 are connected by lift span 5 with lower support parts 4, the height of the bracing or strutting arrangement that lift span 5 can adjusting screw(rod) be repaired.In order well to play a supporting role, the bracing or strutting arrangement quantity of screw rod reparation is at least two, the screw rod that will repair is placed on bracing or strutting arrangement, and according to the phase mutual edge distance between the length adjustment bracing or strutting arrangement of screw rod, screw rod carries out axial rotation by rotatable parts 1 side weld limit.
It is simple that the bracing or strutting arrangement that the utility model screw rod is repaired is made processing, easy to operate, can by lift span, carry out the height of adjusting device, according to the length of screw rod, regulates freely the distance between support, can be widely used in actual production.
