Description

Technical Field

[0001] This utility model relates to the field of drawing die technology, specifically a floating drawing die for small-diameter irregular steel pipes. Background Technology

[0002] Small-diameter special-shaped steel pipes refer to steel pipes with smaller diameters and non-circular cross-sectional shapes. They are usually customized and cut according to engineering requirements. Floating drawing dies are a special type of drawing die. Their main feature is that during the drawing process, certain parts of the die can move or float relatively freely to adapt to the deformation of the metal during the drawing process. This design can effectively reduce friction and improve drawing efficiency and quality.

[0003] Since there are many different types of special-shaped steel pipes, different molds need to be selected according to the different styles of steel pipes during the drawing process, and then the molds need to be replaced as a whole. In order to install the molds, an installation structure is usually set on the outside of the molds. More materials are needed to produce the molds, resulting in a certain degree of resource waste. Therefore, in order to solve the above problems, a floating drawing mold for small-diameter special-shaped steel pipes is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a floating drawing die for small-diameter irregular steel pipes to solve the problem of resource waste caused by replacing the entire die.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A floating drawing die for small-diameter irregular-shaped steel pipes includes a die body for penetrating and drawing the irregular-shaped steel pipe. The die body includes a die block and a die ring. The die block has a through hole in the middle that matches the shape of the irregular-shaped steel pipe. The die ring is tightly fitted to the outside of the die block. Positioning blocks are fixedly connected to both sides of the die block. An installation component is provided on one side of the die ring. The installation component includes a rotating block, a threaded rod, a locking block, a threaded sleeve, and a rubber block. A threaded sleeve is fixedly connected inside the die ring. A threaded rod is threadedly connected inside the threaded sleeve. A rotating block is fixedly connected to one end of the threaded rod, and a locking block is rotatably connected to the other end of the threaded rod. Limit grooves are provided on one side of both the die block and the die ring.

[0007] Preferably, the outer side of the rotating block is provided with several anti-slip strips, and the mold block has grooves on both sides, with the grooves and the rotating block fitting tightly together.

[0008] Preferably, the two sides of the card block and the limiting groove opened in the mold block are closely fitted, and the upper and lower sides of the limiting groove opened in the mold block are provided with arc-shaped protrusions.

[0009] Preferably, the upper and lower sides of the card block are fixedly connected with arc-shaped rubber blocks, and the rubber blocks and the arc-shaped protrusions of the limiting grooves opened in the mold block are closely fitted.

[0010] Preferably, the card block is rectangular, and the thickness of the limiting groove on one side of the mold block and the mold ring is greater than the thickness of the card block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the mold body, mold block, mold ring, and positioning block facilitate the positioning effect during mold block installation. The installation components, rotating block, threaded rod, locking block, threaded sleeve, and limiting groove allow the user to control the rotation of the rotating block, thereby controlling the locking block to move into the limiting groove of the mold block and fixing the installed mold block. When the mold body needs to be changed according to the style of the steel pipe, only the mold block needs to be replaced, achieving resource conservation. The rubber block increases the friction between the locking block and the inner wall of the limiting groove, making the locking block more stable after insertion. The anti-slip strip facilitates control of the rotation of the rotating block. Attached Figure Description

[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0018] Please see Figure 1-2 This utility model provides a technical solution:

[0019] A floating drawing die for small-diameter irregular-shaped steel pipes includes a die body 1 for drawing the irregular-shaped steel pipe through it. The die body 1 includes a die block 11 and a die ring 12. The die block 11 has a through hole in the middle that matches the shape of the irregular-shaped steel pipe. The die ring 12 is tightly fitted to the outside of the die block 11. Positioning blocks 2 are fixedly connected to both sides of the die block 11. An installation component 3 is provided on one side of the die ring 12. The installation component 3 includes a rotating block 31, a threaded rod 32, a locking block 33, a threaded sleeve 34, and a rubber block 35. The threaded sleeve 34 is fixedly connected inside the die ring 12. The threaded rod 32 is threadedly connected inside the threaded sleeve 34. The rotating block 31 is fixedly connected to one end of the threaded rod 32, and the locking block 33 is rotatably connected to the other end of the threaded rod 32. Limiting grooves 4 are provided on one side of both the die block 11 and the die ring 12. With the die body 1 and the installation component 3, when the die body 1 needs to be replaced according to the style of the steel pipe, only the die block 11 needs to be replaced, thereby achieving the purpose of saving resources.

[0020] The rotating block 31 has several anti-slip strips 5 on its outer side. The mold block 11 has grooves 6 on both sides. The grooves 6 fit tightly with the rotating block 31 to facilitate the rotation of the rotating block 31. The two sides of the locking block 33 fit tightly with the limiting groove 4 opened in the mold block 11. The upper and lower sides of the limiting groove 4 opened in the mold block 11 are arc-shaped protrusions to facilitate the insertion of the rubber block 35. The upper and lower sides of the locking block 33 are fixedly connected with arc-shaped rubber blocks 35. The rubber blocks 35 fit tightly with the arc-shaped protrusions of the limiting groove 4 opened in the mold block 11 to facilitate the fixing of the locking block 33 after insertion. The locking block 33 is rectangular. The thickness of the limiting groove 4 opened on one side of the mold block 11 and the mold ring 12 is greater than the thickness of the locking block 33 to facilitate the movement of the locking block 33.

[0021] Workflow: When using the floating drawing die for small-diameter shaped steel pipes, first install the die body 1 at the drawing device, insert one end of the shaped steel pipe through the through hole in the die block 11, and pull it through the drawing device until it enters the next process. When it is necessary to draw a different specification of shaped steel pipe, the die block 11 inside the die body 1 needs to be replaced. When using, hold the anti-slip strip 5 on the outside of the rotating block 31 on one side and rotate it to one side, causing the threaded rod 32 to rotate and move inside the threaded sleeve 34. Since one end of the threaded rod 32 is rotatably connected to the clamping block 33, The locking block 33 moves horizontally towards the mold ring 12 within the limiting groove 4 opened in the mold block 11. The rubber blocks 35 on both sides of the locking block 33 are compressed until the locking block 33 is completely moved into the limiting groove 4 opened in the mold ring 12. The other rotating block 31 is rotated in the same way, and then the mold block 11 can be pushed out from the mold ring 12. A suitable mold block 11 is selected and replaced. With the mold body 1 and the mounting component 3, when the mold body 1 needs to be replaced according to the style of the steel pipe, only the mold block 11 needs to be replaced, thereby achieving the purpose of saving resources.
