Abstract
The utility model relates to a plastic extruding machine, in particular to a heat expansion resistant structure of the plastic extruding machine, which comprises a base and a mainframe support frame. The heat expansion resistant structure is characterized in that a dovetail groove is formed at the upper part of the base, the cross section of the dovetail groove is perpendicular to the axes of the mainframe, and a swallow-tailed projection in match with the dovetail groove is arranged at the bottom part of the mainframe support frame. The swallow-tailed projection and the dovetail groove can generate relative displacement, therefore, when the mainframe drives the swallow-tailed projection to move as expanded by heat, the projection can slide relatively in the dovetail groove, thereby preventing the mainframe from extruding the machine frame as expanded by heat.
Description
Technical field
The utility model relates to a kind of extruding machine, especially relates to a kind of anti-heat expansion structure of extruding machine.
Background technology
The groundwork principle of extruding machine is that plastic grain is added in hopper, through processes such as grinding, heating, homogenizing, plasticizings, draws the plastic products of different shape at last according to the difference of extrusion die shape.In the course of work of whole extruding machine, all be under the environment of higher temperature, to carry out, so main frame in the course of the work certain expansion can take place.Thereby produce bigger internal stress, frame is caused extruding.In the drawing process of long-term heat expansion extruding and cooling, frame can cause mechanical fatigue, causes the aging even fracture of frame.And many useful explorations have all been made in various improvement to extruder (this paper claims extruding machine) structure now, application number provides a kind of have height two-stage frame, easy-to-dismount host platform for 200420087750.9 host platform, dismounting and convenient transportation have been reached, effects such as mechanical disorder is easy to maintenance, and is safe in utilization.Application number is that 200420095049.1 utility model discloses a kind of multi-layer co-extruded section bar extruder unit, comprise two extruders at least, above-mentioned extruder is installed on the same support side by side, wherein the discharging opening of an extruder has feeding mouth by a linear tube connector with a head die and is connected, and the discharging opening of all the other extruders is connected with the feeding mouth of above-mentioned extrusion die by an elbow type spherical union that has the through hole of axle.Owing to adopt the elbow type spherical union to connect, dissolved because that the barrel of different extruders and connector thereof expand with heat and contract with cold is inconsistent and to the extruding force or the tensile force of connector, thereby satisfied arts demand.More than this several patents all solved some practical problems to a certain extent about extruder, as after all be exactly for dissolve extruder because of expand with heat and contract with cold according to negative consequence.But, do not notice the problem that collapses between main frame and the frame, and consequent harm is also very big because it is to be used in the combination of many extruders.
Summary of the invention
The utility model mainly is to solve the existing in prior technology main frame to shine into distortion and the technical problem that wears out and wait because of heat expansion produces extruding with the easy of frame.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of anti-heat expansion structure of extruding machine, comprise base, main frame bracing frame, it is characterized in that described base top is provided with a dovetail groove, the cross section of dovetail groove and the axis normal of main frame, main frame bracing frame bottom is provided with a swallow-tail form projection, and this projection and above-mentioned dovetail groove are suitable.Described swallow-tail form projection and dovetail groove can have relative displacement, so when main frame was subjected to displacement because of expanded by heating drives the swallow-tail form projection, this projection can slide in dovetail groove relatively.Make main frame can not produce extruding because of expanded by heating and frame.
As preferably, the groove that connects before and after the centre of the bottom of described swallow-tail form projection is provided with.This each and every one groove has been arranged, can reduce location area, be beneficial to the location more, also the processing for locating surface provides convenience.
As preferably, the L type breach that connects before and after the top edge of the described swallow-tail form projection left and right sides is respectively equipped with.Owing to move between this dovetail groove and the swallow-tail form projection,, also can reach antirust effect simultaneously so need apply oil to be lubricated.Described L type breach has been arranged, can conveniently add lubricating oil.
Therefore, the utlity model has simple and reasonable, solve extruder main frame and frame the technical problem of extruding.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of partial enlarged drawings of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: with reference to the accompanying drawings 1, shown in the accompanying drawing 2, the utility model has main frame 3 and frame 1 to constitute, and the bottom of main frame is provided with a dovetail projection 2, and the axis of its cross section and main frame is perpendicular.A dovetail groove is arranged at the top of frame, matches with the dovetail projection.The bottom of dovetail projection is provided with a groove 22, and this groove connects before and after the direction of main engine axis.The upper end of the left and right sides of dovetail projection is respectively equipped with a L shaped breach 21.
When main frame expanded by heating or cooling contraction, can drive the dovetail projection and in groove, slide, so the extruding between main frame and the frame can not take place.
Claims (3)
1. the anti-heat expansion structure of an extruding machine, comprise base, main frame bracing frame, it is characterized in that described base top is provided with a dovetail groove, the cross section of dovetail groove and the axis normal of main frame, main frame bracing frame bottom is provided with a swallow-tail form projection, and this projection and above-mentioned dovetail groove are suitable.
2. the anti-heat expansion structure of extruding machine according to claim 1 is characterized in that the centre of the bottom of described swallow-tail form projection is provided with the groove that front and back connect.
3. the anti-heat expansion structure of extruding machine according to claim 1 and 2 is characterized in that the top edge of the described swallow-tail form projection left and right sides is respectively equipped with the L type breach that front and back connect.
