[0032] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0033] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] like Figure 1-7As shown, a cold-drawn outer die jacket comprises a jacket cone 101 and a retaining ring 102. The jacket cone 101 is provided with a receiving groove for placing the outer die, and the retaining ring 102 is an annular structure, and the inner diameter of the retaining ring 102 is larger than the diameter of the receiving groove; the retaining ring 102 is provided with a fixing piece, and the jacket cone 101 is provided with a fixing groove corresponding to the fixing piece, and when the fixing piece is inserted into the fixing groove, the retaining ring 102 is fixed to the jacket cone 101.

[0035] Specifically, a first movable groove is provided on the retaining ring 102, and the fixing member is in the first movable groove; the fixing member includes a movable plate 106, a barb 108 and a return spring 107, the barb 108 is provided at the bottom end of the movable plate 106, and the return spring 107 is provided between the movable plate 106 and the first movable groove.

[0036] The retaining ring 102 is rotatably connected to a movable ring 103, and a plurality of protrusions 1031 are provided on the inner wall of the movable ring 103; a first grip 104 is provided on the retaining ring 102, and a second grip 105 is provided on the movable ring 103; the first grip 104 and the second grip 105 are provided to facilitate the rotation of the movable ring 103.

[0037] Through the setting of the fixing part, after the outer mold is placed on the jacket cone 101, the retaining ring 102 is directly buckled on the jacket cone 101, the movable plate 106 is inserted into the fixing groove, and the barb 108 is pressed against the fixing groove to fix the retaining ring 102. The retaining ring 102 blocks the edge of the receiving groove, so that the outer mold cannot fall out of the receiving groove, thereby achieving the fixation of the outer mold; the outer mold is fixed to the jacket cone 101 by the retaining ring 102. The purpose of the device is that the outer mold jacket can be shared. For cold-drawn steel pipes with small outer diameters, the weight of the outer mold design can be reduced by sharing the outer mold jacket, saving the purchase price of the outer mold, and at the same time achieving the required steel pipe cold drawing effect. This method is simple and convenient to operate, and can greatly save the use cost of the cold drawing mold.

[0038] When the retaining ring 102 is removed, the second handle 105 is pushed to move and the second handle 105 is pushed to a position overlapping with the first handle 104. The protrusion 1031 abuts against the movable plate 106 to push the movable plate 106 to move, so that the barb 108 is disengaged from the fixing groove to quickly remove the retaining ring 102.

[0039] Furthermore, a second movable groove is provided on the inner wall of the retaining ring 102 , and an extending baffle 109 is provided in the second movable groove.

[0040] A third movable groove is provided on the extension baffle 109, and a push rod 110 is provided in the third movable groove. A through hole is provided at one end of the second movable groove, and the push rod 110 passes through the through hole; a slider 1101 is provided on the push rod 110, and a slide groove 1091 for the slider 1101 to move is provided on the inner wall of the third movable groove, and a first annular groove 1092 is provided at one end of the slide groove 1091, and a second annular groove 1093 is provided at the other end; the push rod 110 is in the third movable groove and the through hole when not in use. When it is necessary to push the extension baffle 109 to move, the push rod 110 is rotated so that the slider 1101 and the slide groove 1091 are opposite to each other, and then the push rod 110 is pulled outward. After the slider 1101 moves to the second annular groove 1093, the push rod 110 is rotated so that the slider 1101 and the slide groove 1091 are staggered. At this time, pushing the push rod 110 can drive the extension baffle 109 to move together.

[0041] The extension baffle 109 is provided with a positioning block 111 and a fourth movable groove for the positioning block 111 to move, the positioning block 111 is provided with a connecting spring 1111, and a plurality of positioning grooves 112 corresponding to the positioning block 111 are provided on the inner wall of the second movable groove; one end of the positioning block 111 is an arc-shaped structure; the arrangement of the positioning block 111 and the positioning groove 112 enables the extension baffle 109 to stop after moving a specified distance, thereby providing a plurality of gears for the extension baffle 109; through the arc-shaped structure at one end of the positioning block 111, the positioning block 111 is disengaged from the positioning groove 112 under the action of thrust, thereby facilitating the normal movement of the extension baffle 109 in the second movable groove.

[0042] By extending the baffle 109 , the applicable range of the baffle ring 102 is increased, and more types of external molds can be satisfied.

[0043] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used.
