Abstract
A band brake structure of a compression molding machine comprises a band brake and a guide column; the band brake is of a Huff structure; and the guide column is embraced by the upper part and the lower part of the band brake. The band brake structure is characterized in that the band brake is provided with relief notches. The relief notches are symmetrically arranged on extruded end surfaces of the upper part and the lower part of the band brake. The relief notches are C-shaped grooves or U-shaped grooves. According to the band brake structure of the compression molding machine, unique relief grooves are arranged on the extruded end surfaces of the band brake; through finite-element analysis and optimal design, the maximum stresses of tooth parts of the band brake and the guide column are effectively reduced, the stresses on the first few teeth at the extruded side are reduced remarkably, and the stressing uniformity of the overall tooth section is effectively improved. The band brake structure of the compression molding machine has a simple and rational structure, and the service life of the compression molding machine is improved.
Description
Technical field
The utility model relates to the band-type brake structure of a kind of compression molding forming machine, particularly a kind of compression molding forming machine.
Background technology
Band-type brake mechanism is a vitals on the double-plate compression molding forming machine, and its main body is made up of two movable Kazakhstan furan structures.When its obvolvent guide pillar, band-type brake tooth top (a plurality of tooth) inserts the guide pillar teeth groove, makes itself and guide pillar keep static relatively; Its end face can receive the extruding force that high-voltage lock mould produces; This extruding force finally is delivered on band-type brake and the contacted tooth of guide pillar, can produce bigger stress on the respective teeth, because the influence of various factors such as the mismachining tolerance of each tooth and material self character; The stress intensity of each tooth is uneven on band-type brake and the guide pillar; Especially near several leading tooth of the stressed side of band-type brake, stress is very big, has reduced the service life of relevant each parts.Therefore, be necessary further improvement and perfect.
The utility model content
The purpose of the utility model aims to provide a kind of simple and reasonable, band-type brake structure that can effectively reduce the most heavily stressed, as to improve service life compression molding forming machine, to overcome weak point of the prior art.
Press the band-type brake structure of a kind of compression molding forming machine of this purpose design, comprise band-type brake and guide pillar, band-type brake is Kazakhstan furan structure, this band-type brake upper and lower part obvolvent guide pillar, and its architectural feature is on band-type brake, to be provided with compensating groove.
Said band-type brake is that two mobilizable Kazakhstan furan structures constitute, and compensating groove is symmetricly set on the end face that is squeezed of band-type brake upper and lower part.
Said compensating groove is C shape annular groove or U-loop groove.
Said band-type brake and guide pillar adopt the non-helical ring toothing that matches.
The utility model adopts unique compensating groove design at the end face that is squeezed of band-type brake; Through finite element analysis and optimal design; Effectively reduce the most heavily stressed of band-type brake and guide pillar tooth portion, the several leading tooth stress of squeeze side obviously reduces, and the stressed uniformity of whole tooth section is effectively improved.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the assembled sectional view of band-type brake and guide pillar among the embodiment.
Among the figure: 1 is band-type brake, and 11 is compensating groove, and 2 is guide pillar.The suffered extruding force and receive force direction when high-voltage lock mould of direction indication band-type brake shown in F and the arrow.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 2, the band-type brake structure of this compression molding forming machine comprises band-type brake 1 and guide pillar 2, and band-type brake 1 is two mobilizable Kazakhstan furan structures, this band-type brake 1 upper and lower part obvolvent guide pillar 2, and on band-type brake 1, be provided with compensating groove 11.Compensating groove 11 is symmetricly set on the end face that is squeezed of band-type brake 1 upper and lower part.Compensating groove 11 is C shape annular groove or U-loop groove.The design of compensating groove 11 effectively reduces the most heavily stressed of band-type brake 1 and guide pillar 2 tooth portions, and the several leading tooth stress of squeeze side obviously reduces, and the stressed uniformity of whole tooth section is effectively improved.Band-type brake 1 adopts the non-helical ring toothing that matches with guide pillar 2.
During work, the tooth portion obvolvent of the tooth portion of band-type brake 1 upper and lower part and guide pillar 2 makes to keep static relatively between band-type brake 1 and the guide pillar 2 together.
Claims (4)
1. the band-type brake structure of a compression molding forming machine comprises band-type brake (1) and guide pillar (2), and band-type brake is for breathing out the furan structure, and this band-type brake upper and lower part obvolvent guide pillar is characterized in that on band-type brake, being provided with compensating groove (11).
2. according to the band-type brake structure of the said compression molding forming machine of claim 1, it is characterized in that said band-type brake (1) is that two mobilizable Kazakhstan furan structures constitute, compensating groove (11) is symmetricly set on the end face that is squeezed of band-type brake (1) upper and lower part.
