Abstract
The utility model discloses a continuous mill core rod extension rod. The continuous mill core rod extension rod comprises a rod body, a first replacing part, a second replacing part and a trapezoid block, wherein the first replacing part is provided with a first protrusion, the upper side and the lower side of the first protrusion are respectively provided with first threads, the first replacing part is connected with the rod body through a first lock catch, one end of the second replacing part is provided with second threads, the second replacing part is connected with the trapezoid block through the second threads, and the second replacing part is connected with the rod body through a second lock catch. The continuous mill core rod extension rod can replace the abraded portion of the threads, and therefore manufacturing cost can be lowered.
Description
Technical field
The utility model relates to a kind of extension rod, particularly a kind of tandem mill plug extension rod.
Background technology
In metallurgical industry, the operation of rolling is a main processes of stress metal processing, and tandem mill is a kind of can raising labour productivity and the advanced method of rolling and so on, its main feature is pricked the metal while among some frames, and verifies same putting to being rolled the capable shape of the certain section of final formation.A kind of tandem mill plug extension rod in use for some time, because the wearing and tearing of screw thread generally can only be scrapped and process, can increase manufacturing cost like this.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of tandem mill plug extension rod, and it can replace the wearing part of screw thread, reduces like this manufacturing cost.
For solveing the technical problem, the utility model provides a kind of tandem mill plug extension rod, it is characterized in that, it comprises the body of rod, the first replacement portion, the second replacement portion, trapezoid block, the first replacement portion is provided with first projection, the both sides up and down of the first projection are provided with the first screw thread, between the first replacement portion and the body of rod, by the first snap close, connect, one end of the second replacement portion is provided with the second screw thread, the second replacement portion is threaded by second with trapezoid block, between the second replacement portion and the body of rod, by the second snap close, is connected.
Preferably, the described body of rod is provided with one second projection and first groove, and the first replacement portion is provided with second groove, and the second replacement portion is provided with the 3rd projection, and the second projection is embedded in the second groove, and the 3rd projection is embedded in the first groove.
Preferably, described the second projection and the first groove lay respectively at the both sides of the body of rod.
Positive progressive effect of the present utility model is: a kind of tandem mill plug of the utility model extension rod can be replaced the wearing part of screw thread, reduces like this manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of tandem mill plug of the utility model extension rod.
Fig. 2 is the structural representation of the body of rod in the utility model.
The specific embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As depicted in figs. 1 and 2, a kind of tandem mill plug of the utility model extension rod comprises the body of rod 1, the first replacement portion 2, the second replacement portion 3, trapezoid block 6, the first replacement portion 2 is provided with first projection 21, the both sides up and down of the first projection 21 are provided with the first screw thread 211, between the first replacement portion 2 and the body of rod 1, by the first snap close 4, connect, one end of the second replacement portion 3 is provided with the second screw thread 31, the second replacement portion 3 is connected by the second screw thread 31 with trapezoid block 6, between the second replacement portion 3 and the body of rod 1, by the second snap close 5, is connected.
The body of rod 1 is provided with 11 and first grooves 12 of one second projection, the first replacement portion 2 is provided with second groove 22, the second replacement portions 3 and is provided with the 3rd projection 32, the second projections 11 and is embedded in the second groove 22, the 3rd projection 32 is embedded in the first groove 12, convenient for assembly like this.11 and first grooves 12 of the second projection lay respectively at the both sides of the body of rod 1.
After the first screw thread and the second thread abrasion, the first replacement portion and the second replacement portion are replaced by the first snap close and the second snap close respectively, a kind of tandem mill plug of the utility model extension rod can be replaced the wearing part of screw thread like this, reduces like this manufacturing cost.
Although more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and are not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
