Abstract

The utility model discloses a rotatable cold-drawing die for steel pipes, which comprises a box body and a die body, wherein the die body is arranged in the box body, the upper end surface and the lower end surface in the box body are respectively provided with a groove, and a shaft sleeve is arranged in each groove; the utility model has the advantages of reasonable design, convenient to use can rotate the regulation to the mould body according to the actual production demand to reduce and draw produced stress and steel pipe itself from the flaw in area to drawing the influence of welded tube, improved the production quality of cold-drawing welded steel.

Description

Rotatable cold-drawing mould for steel pipe

Technical Field

The utility model belongs to the technical field of the mould for the cold drawn steel pipe and specifically relates to a rotatable mould for cold drawn steel pipe is related to.

Background

Cold-drawn welded pipe can use the mould to draw usually to draw into the little steel pipe of bore with the big steel pipe of bore, traditional mould is fixed dead usually, can't carry out position control according to the in-service use demand, makes the steel pipe often can lead to the quality after the steel pipe is drawn relatively poor because drawing produced stress or the flaw of steel pipe self-band among the process, is unfavorable for the high quality production of cold-drawn welded pipe.

SUMMERY OF THE UTILITY MODEL

The utility model provides a rotatable cold-drawing steel pipe die for solving the problems, which comprises a box body and a die body, the die body is arranged in the box body, grooves are respectively arranged on the upper end surface and the lower end surface in the box body, a shaft sleeve is arranged in the groove, rotating shafts are arranged on the upper side and the lower side of the die body, the other end of each rotating shaft is connected with the shaft sleeve, two fixed blocks are arranged at the lower end of the front end surface of the box body at intervals, a screw rod is arranged between the two fixed blocks, the right end of the screw rod is provided with a motor and is driven by the motor, the screw rod is provided with a moving block, the movable block is fixed to the lower end of the die body, a sliding groove is formed in the upper end of the front end face of the box body, a sliding block is arranged in the sliding groove, and the sliding block is fixed to the upper end of the die body.

The utility model has the advantages that: the utility model has the advantages of reasonable design, convenient to use can rotate the regulation to the mould body according to the actual production demand to reduce and draw produced stress and steel pipe itself from the flaw in area to drawing the influence of welded tube, improved the production quality of cold-drawn welded steel.

in the figure: 1. a box body; 2. a slide rail; 3. a mold body; 4. a slider; 5. a motor; 6. a moving block; 7. a screw rod; 8. a fixed block; 9. a groove; 10. a shaft sleeve; 11. and rotating the shaft.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

As shown in fig. 1 and 2, a rotatable cold-drawing steel tube die comprises a box 1 and a die body 3, wherein the die body 3 is arranged in the box 1, the box 1 is provided with a groove 9 on both the upper and lower end surfaces, a shaft sleeve 10 is arranged in the groove 9, the die body 3 is provided with a rotating shaft 11 on both the upper and lower sides, the other end of the rotating shaft 11 is connected with the shaft sleeve 10, two fixing blocks 8 are arranged at the lower end position of the front end surface of the box 1 at intervals, a lead screw 7 is arranged between the two fixing blocks 8, the right end of the lead screw 7 is provided with a motor 5 and is driven by the motor 5, the lead screw 7 is provided with a moving block 6, the moving block 6 is fixed with the lower end of the die body 3, the upper end position of the front end surface of the box 1 is provided with a chute 2, and a slide block 4 is arranged in the chute 2, the slide block 4 is fixed with the upper end of the die body 3.

In the use, when the whole regulation that needs rotate right of mould body 3 makes, accessible motor 5 drive lead screw 7 rotates to drive movable block 6 and move right, move the in-process at movable block 6 right, mould body 3 can rotate right thereupon, and in the same way, mould body 3 also can rotate left when moving the movable block 6 left.

The arrangement of the rotating shaft 11 and the shaft sleeve 10 can facilitate the die body 3 to rotate leftwards or rightwards.

The arrangement of the sliding groove 2 and the sliding block 4 can enable the die body 3 to be more stable when rotating leftwards or rightwards.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
