Abstract
The utility model relates to a part of a saw cutting device, in particular to a pairing saw blade which can rotate oppositely around the same axis. The pairing saw blade comprises a first saw blade and a second saw blade which are arranged on a main shaft, can rotate oppositely around the main shaft, and are respectively provided with a saw blade body and a cutting element distributed along the circumference of the saw blade body, and the lower surface of the first saw blade is attached with the upper surface of the second saw blade. Devices do not exist between the two saw blades, so that the pairing saw blade has the advantages of simple structure, easy processing, low cost and batch production.
Description
Technical field
The utility model relates to a kind of parts of saw cutting device, relates in particular to a kind of Pair of saw blades around same axis reverse rotation.
Background technology
The Pair of saw blades of same axis reverse rotation has than monolithic saw that cutting speed is fast, steady operation and other merits, therefore is used widely.Isolated component is set to increase the distance between two saw blades between two saw blades of traditional Pair of saw blades; Like publication number is that CN1516640A discloses a kind of Pair of saw blades; Two saw blades are coaxial opposite spin; In the middle of two saw blades, have one to reach that the interval facility in the space is connected on the body of at least one saw blade between two saw blades, it is own and can slide along the periphery of another relative saw blade in order that when cutting, support.But this Pair of saw blades will be provided with facility at interval between two saw blades, and processing is complicated, cost is high, be inappropriate for batch process.
The utility model content
The Pair of saw blades that the purpose of the utility model provides a kind of processing simple in structure, easy, cost is low and be suitable for producing in batches.
The purpose of the utility model mainly is achieved through following proposal: a kind of Pair of saw blades; Comprise first saw blade and second saw blade that are arranged on the main shaft; Described first saw blade and second saw blade are around the main shaft reverse rotation; The cutting element that described first saw blade and second saw blade all have blade bodies separately and distribute along blade bodies ring week, the lower surface of described first saw blade pastes with the upper surface of second saw blade mutually.
Adopt the present technique scheme, the lower surface of described first saw blade pastes with the upper surface of second saw blade mutually, and first saw blade and second saw blade are better pressed close to each other, makes first saw blade free parallel sliding on second saw blade.Owing to continuously at a distance from the facility setting, reduced the manufacturing procedure in the saw blade production process between two saw blades, eliminated the saw blade machining complexity, make the utlity model has simple in structure, be prone to processing, cost is low and the characteristics that are suitable for producing in batches.
As preferably, be respectively equipped with corresponding a plurality of louvre on the blade bodies of described first saw blade and second saw blade.On two saw blades, louvre is set, so not only can adjusts the saw blade internal stress, because fricative heat in time distributes, improve the service life of saw blade in the time of also can two saw blades being rotated.
As preferably, described louvre is uniformly distributed on the blade bodies around central axis.Louvre evenly distributes, then can be with distributing uniformly owing to fricative heat between two saw blades.
As preferably, described louvre be shaped as circle or footmark shape.Circular port is easy to processing, and louvre is the footmark shape, has not only increased the area of louvre but also has possessed the characteristics of good looking appearance.
The utility model between two saw blades continuously at a distance from the facility setting, make first saw blade can be on second saw blade free parallel sliding, therefore have simple in structure, be prone to processing, cost is low and the advantage that is suitable for producing in batches.
Description of drawings
Fig. 1 is the utility model cross-sectional structure sketch map;
Fig. 2 is the vertical view of the utility model.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
A kind of Pair of saw blades; As shown in Figure 1; Comprise first saw blade 1 and second saw blade 2 that are arranged on the main shaft; Described first saw blade 1 and second saw blade 2 be around the main shaft reverse rotation, the cutting element 5,6 that described first saw blade 1 and second saw blade 2 all have blade bodies 3,4 separately and distribute along blade bodies ring week, and the lower surface 7 of described first saw blade pastes with the upper surface 8 of second saw blade mutually.Be equipped with on the blade bodies 3,4 of described first saw blade 1 and second saw blade 2 around central axis and be uniformly distributed in circular louvre 11 and footmark shape louvre 11 on the blade bodies; As shown in Figure 2, the circular louvre 11 on first saw blade 1 is corresponding with footmark shape louvre 9 with the circular louvre 11 on second saw blade with footmark shape louvre 11.
In the utility model; The lower surface 7 of first saw blade pastes with the upper surface 8 of second saw blade mutually; First saw blade 1 and second saw blade 2 are better pressed close to each other, made first saw blade 1 can free parallel sliding on second saw blade 2, two saw blades be provided with corresponding around the equally distributed a plurality of louvres 9 of central axis; Because fricative heat in time distributes uniformly, improve the service life of Pair of saw blades in the time of so just can two saw blades being rotated.Simultaneously since between two saw blades continuously at a distance from the facility setting, therefore the utlity model has the characteristics that processing, cost are low, be suitable for producing in batches that are prone to.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should understand in addition; After the content of having read the utility model instruction; Those skilled in the art can make some changes or modification to the louvre structure such as Pair of saw blades, but these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Claims (3)
1. Pair of saw blades; Comprise first saw blade and second saw blade that are arranged on the main shaft; Described first saw blade and second saw blade are around the main shaft reverse rotation; The cutting element that described first saw blade and second saw blade all have blade bodies separately and distribute along blade bodies ring week is characterized in that the lower surface of described first saw blade pastes with the upper surface of second saw blade mutually.
2. a kind of Pair of saw blades according to claim 1 is characterized in that, is respectively equipped with corresponding a plurality of louvre on the blade bodies of described first saw blade and second saw blade.
