Abstract
The invention discloses a blanking flow channel which comprises a tubular flow channel body with the two ends open and a fixing seat used for allowing the flow channel body to penetrate. The blanking flow channel is characterized in that at least three elastic elements are arranged on the inner wall of the fixing seat, and the elastic elements clamp the flow channel body. The elastic elements are arranged on the inner wall of the fixing seat, and the number of the elastic elements is three. The elastic elements can automatically conduct centering on the flow channel body and clamp the flow channel body under the action of elastic force. When the blanking flow channel is mounted, one ends of the elastic elements only need to abutting against the outer wall of the flow channel body. When the blanking flow channel is dismounted, one ends of the elastic elements are compressed to enable the ends of the elastic elements to be away from the outer wall of the flow channel body. The blanking flow channel is simple in structure, and convenient to mount and dismount.
Description
Technical field
The present invention relates to mechanical field, the blanking runner in especially a kind of punching course.
Background technology
Runner in the Sheet Metal Forming Technology, it tubulose runner body and one that comprises both ends open is used for holding the holder that the runner body passes, and workpiece can enter from this runner body one end, is flowing out by the other end.
Disclose a kind of blanking runner in the prior art, it adopts screw stationary flowpath body and holder, and this structure is installed difficulty, length consuming time. and dismounting also needs one period long period after production is finished.
Summary of the invention
The technical problem to be solved in the present invention provides easy for installation, quick detachable ground blanking runner.
For addressing the above problem, the invention provides a kind of blanking runner, the tubulose runner body and one that comprises both ends open is used for holding the holder that described runner body passes, and it is characterized in that: described holder inwall is provided with at least three flexible members, and described flexible member clamps described runner body.
As a further improvement on the present invention, described flexible member is the bulb plug screw, and it comprises spherical top and the flexible member main body that is connected with described elasticity original paper top by spring.
As a further improvement on the present invention, also be provided with at least one annular groove on the external wall of described runner, shown in annular groove comprise the upper cell wall that is arranged on the top, and the lower cell wall that is arranged on the below, the top of described flexible member is supported on described upper cell wall and the lower cell wall.
As a further improvement on the present invention, described flexible member is four.
Beneficial effect of the present invention is, the holder inwall is provided with flexible member, and the quantity of flexible member is three, can be to the self-centering of runner body, and under the effect of elastic force, clamp, only need when this structure is installed flexible member one end is withstood on the outer wall of this runner body, compress this flexible member one end during dismounting and get final product away from the external wall of this runner, simple in structure, it is all convenient to install, dismantle.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1;
Wherein: 2-runner body; The 6-flexible member; The 8-holder; The 10-groove; The upper cell wall of 12-; Cell wall under the 14-.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As depicted in figs. 1 and 2, the tubulose runner body 2 and that the present invention includes both ends open is used for holding the holder 8 that runner body 2 passes, and holder 8 inwalls are provided with three flexible members 6, and flexible member 6 clamps runner body 2.In the present invention, holder 8 inwalls are provided with flexible member 6, and the quantity of flexible member 6 is three, can be to 2 self-centerings of runner body, and under the effect of elastic force, clamp this runner body, in addition, this flexible member 6 also can be four, and it is conducive to improve the stability of clamping and avoids vibrations.Only need when this structure is installed flexible member 6 one ends are withstood on the outer wall of this runner body 2, compress these flexible member 6 one ends during dismounting and get final product away from these runner body 2 outer walls, simple in structure, it is all convenient to install, dismantle.The kind of this flexible member 6 is a lot, for example in the present invention, flexible member 6 has been selected the bulb plug screw, it comprises spherical top and the flexible member main body that is connected with this top by spring, adopt this structure, this flexible member 6 is that higher pair is connected with runner body 2 outer walls, and the free degree of restriction is few, and this runner body 2 is free to rotate.
In a preferred embodiment of the present invention, also be provided with at least one annular groove 10 on runner body 2 outer walls, annular groove 10 comprises the upper cell wall 12 that is arranged on the top, and the lower cell wall 14 that is arranged on the below, the top of this annular groove 10 is supported on upper cell wall 12 and the lower cell wall 14, under this structure, this flexible member 6 can axially position and fix runner body 2, prevents that it from sliding vertically.
The above only is preferred embodiment of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
