Abstract
The utility model discloses a crooked adjustment mechanism of PVC -U profile shapes, first platen (1) on having second platen (2) and lieing in the second platen is settled to the left L type support and the right L type support of interval opposition on it includes base (8) and lies in the base between left L type support and the right L type support, and first platen one end is passed through reference column (3) swing joint and is served at second platen no. 1, the rigid coupling has the total accent screw (7) that passes second platen and first platen screw -thread fit on the base between left side L type support and the right L type support, regulating plate (4) swing joint is passed through respectively on left L type support and right L type support in first platen both ends. The beneficial effects of the utility model are that through skew section bar center about upper and lower, adjust the section bar bending for a section bar reversed stress, at the section bar section bar center of still squinting on the unhardened basis to the surface quality and the physical properties of protection type material.
Description
Technical field
The utility model relates to plastic section extruding device, particularly relates to PVC-U profile shapes and bends governor motion.
Background technology
Plastic-profile extrusion-molding technology is a kind of parison extrusion die being made melting by extruder heating, pressurization, through a continuous process of the cooling fast of dry type sizing (stock mould), wet type sizing (water tank), solidification.Generally by extruder, extrusion die, stock mould. water tank, shaping platform, section bar, hauling machine and crawler belt are formed, section bar passes through die head, enter sizing, because PVC-U profile shapes will through heating in extrusion molding process, the heat exchanging process such as plasticizing and cooling and shaping, simultaneously, also to shear by extruder, friction, the cooling meat of stock mould, vacuum suction, the effect of the various power such as traction.Therefore, in extrusion molding process, be easier to produce internal stress, the existence of internal stress is the key factor of shape bending.Solved section bar internal stress in the past, generally adopted: 1, regulated water route and gas circuit, stifled stock mould cooling water and stock mould cooling vacuum etc.Strengthen cooling water inflow and the vacuum suction of the tensile stress side that section bar bears.The bending adjustment of this control method to section bar is not clearly.2, corrected by infrared ray, roasting curved interior, this correction is to Surface of profile poor quality.3, adopt the method adjustment at mechanical bias center, namely produce the linearity regulating section bar center.The method of adjustment section bar off center was the linearity by skew water tank and stock mould center in the past.But this control method, because section bar is hardening by having cooled after stock mould, at this moment adjustment can make the surface of section bar there is cut, the mass defects such as bright line.
Utility model content
The technical problems to be solved in the utility model is that existing PVC-U profile shapes control method can leave the defect such as cut, bright line on the surface of section bar, provides a kind of PVC-U profile shapes to bend governor motion for this reason.
The technical solution of the utility model is: a kind of PVC-U profile shapes bends governor motion, it comprises pedestal and is positioned at the opposed left L-type support in interval on pedestal and right L-type support, be mounted with the second platen between described left L-type support and right L-type support and be positioned at the first platen on the second platen, described first platen one end is movably connected on second platen one end by locating dowel; Pedestal between described left L-type support and right L-type support is connected with the total tune screw through the second platen and the first platen threaded engagement; Described first platen two ends are movably connected in left L-type support and right L-type support respectively by adjustable plate.
The improvement of such scheme is that the described first platen other end is movably connected on the second platen other end by rotating shaft, and described total tune screw both sides make end and the vertical adjusting screw contacted bottom the first platen through the second platen.
The beneficial effects of the utility model utilize mechanical performance, by offseting section bar center up and down, regulates shape bending to section bar one reversal of stress; Section bar also unhardened basis offset section bar center, thus the surface quality of protection section bar and physical property; Carry out adjustment section bar center at stock mould feed end, and discharge end center is constant, can pass through stock mould smoothly when section bar can be made to draw.

Fig. 3 is the top view of Fig. 2;
In figure, the 1, first platen, the 2, second platen, 3, locating dowel, 4, adjustable plate, 5, rotating shaft, 6, vertical adjusting screw, 7, always adjust screw, 8, pedestal.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As Figure 1-3, the utility model comprises pedestal 8 and is positioned at the opposed left L-type support in interval on pedestal and right L-type support, the first platen 1 being mounted with the second platen 2 between described left L-type support and right L-type support and being positioned on the second platen, described first platen one end is movably connected on second platen one end by locating dowel 3; Pedestal between described left L-type support and right L-type support is connected with the total tune screw 7 through the second platen and the first platen threaded engagement; Described first platen two ends are movably connected in left L-type support and right L-type support respectively by adjustable plate 4.
Between stock mould during use, this device being placed in section bar, section bar always adjusts screw to depart from the first platen through out-of-date by regulating between the first platen and the second platen, control the first platen by adjustable plate again to move left and right relative to the second platen, regulate the degree of bending right and left of section bar with this.
Further, the first platen other end can be made to be movably connected on the second platen other end by rotating shaft 5, described total tune screw both sides make end and the vertical adjusting screw 6 contacted bottom the first platen through the second platen.By regulating total screw of adjusting to depart from the first platen, then regulating vertical adjusting screw to move up and down with jack-up first platen, the first platen being moved up and down around rotating shaft, regulates the flexibility up and down of section bar with this.
