Description

Technical Field

[0001] This utility model relates to an automated three-wire cold drawing device for high-performance stainless steel pipes. Background Technology

[0002] In the existing technology, small-diameter high-performance stainless steel pipes are generally cold-drawn using an automated three-line cold drawing device to improve processing efficiency; however, this equipment has the following shortcomings: the three cold drawing dies of the cold drawing device are installed separately on the cold drawing base, which is relatively complicated to install. After installation and after a period of use, the cold drawing dies need to be centered and adjusted one by one, which is also quite troublesome to use. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automated three-line cold drawing device for high-performance stainless steel pipes. The cold drawing die is quickly installed onto the cold drawing seat, and the cold drawing die and the cold drawing seat are reliably fixed without the need for frequent adjustments.

[0004] The technical solution of this utility model is: an automated three-line cold drawing device for high-performance stainless steel pipes, including a cold drawing seat, wherein the cold drawing seat is provided with an integrally formed cold drawing die having three die holes. The front end of the cold drawing base is provided with four columns, and the back of each column has a guide groove. The rear end of the cold drawing base is provided with a wall plate, and the wall plate has grooves corresponding to each die hole. The front of the cold drawing die has guide protrusions corresponding to each guide groove. The cold drawing die is inserted and fixed between the four columns and the wall plate. The guide protrusions match the corresponding guide grooves. The larger end of the three die holes of the cold drawing die is located between each pair of columns, and the smaller end of the three die holes of the cold drawing die is set to each groove.

[0005] Furthermore, the front of the column is provided with multiple countersunk holes, and each of the guide protrusions is provided with a screw hole corresponding to the countersunk hole. The cold drawing die is inserted into the cold drawing base and fixed to each column by multiple fixing bolts.

[0006] Specifically, the column, wall panel, and cold-drawn base are integrally formed structures.

[0007] Specifically, the front of each of the columns is trapezoidal.

[0008] Specifically, the wall panel is a thickened wall panel.

[0009] Specifically, the guide groove is a dovetail groove, and the shape of the guide protrusion corresponds to the guide groove.

[0010] Furthermore, the bottom of the cold drawing die is provided with chamfers at both the front and rear ends.

[0011] Furthermore, the cold-drawing seat is fixed to the frame by two rows of fixing bolts.

[0012] The beneficial effects of this utility model are as follows: This utility model has the advantages of simple installation and no need for individual adjustment. During installation, it is only necessary to use a lifting tool to lift the cold drawing die and insert it between the four columns and the wall panel. Through the matching of the guide protrusions and guide grooves, and the connection of each countersunk hole with the corresponding screw hole, the cold drawing die can be easily positioned. It should be noted that each guide protrusion also plays a role in strengthening the cold drawing die. The columns set on the front mainly play a role in limiting and guiding the cold drawing die, while the wall panel set on the back mainly plays a supporting role. When the steel pipe is cold drawn, the force on the cold drawing die is evenly distributed to the wall panel around the groove, which can ensure the reliability of the entire cold drawing base and the cold drawing die, and there is no need to frequently adjust the cold drawing die.

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Combination Figure 1-3 As shown, an automated three-wire cold drawing device for high-performance stainless steel pipes includes a cold drawing seat 1, on which a cold drawing die 3 is integrally formed and has three die holes 2. The front end of the cold drawing base 1 is provided with four columns 4, and the back of each column 4 has a guide groove 5. The rear end of the cold drawing base 1 is provided with a wall plate 6, and the wall plate 6 is provided with grooves 7 corresponding to each die hole 2. The front of the cold drawing die 3 is provided with guide protrusions 8 corresponding to each guide groove 5. The cold drawing die 3 is inserted and fixed between the four columns 4 and the wall plate 6. The guide protrusions 8 match the corresponding guide grooves 5. The larger end of the three die holes 2 of the cold drawing die 3 is located between each pair of columns 4, and the smaller end of the three die holes 2 of the cold drawing die is respectively set with each groove 7.

[0017] In another embodiment, such as Figure 1 As shown, the front of the column 4 is provided with multiple countersunk holes 9, and each of the guide protrusions 8 is provided with a screw hole corresponding to the countersunk hole 9. The cold drawing die 3 is inserted into the cold drawing base 1 and fixed to each column 4 by multiple fixing bolts.

[0018] The above structure has the advantages of simple installation and no need for adjustment. During installation, the cold drawing die 3 only needs to be lifted by a lifting tool and inserted between the four columns 4 and the wall plate 6. Through the matching of the guide protrusions 8 and the guide grooves 5, and the connection of each countersunk hole 9 with the corresponding screw hole, the cold drawing die 3 can be easily positioned. It should be noted that each guide protrusion 8 also plays a role in strengthening the cold drawing die 3. The columns 4 set on the front mainly play the role of limiting and guiding the cold drawing die 3, while the wall plate 6 set on the back mainly plays the role of support. When the steel pipe is cold drawn, the force on the cold drawing die 3 is evenly distributed on the wall plate 6 around the groove 7, which can ensure the reliability of the entire cold drawing seat 1 and the cold drawing die 3, and there is no need to frequently adjust the cold drawing die 3.

[0019] Specifically, the cold drawing die 3 is a high-hardness alloy integral molding structure.

[0020] In another embodiment, the column 4, wall panel 6 and cold-drawn seat 1 are integrally formed structures.

[0021] In another embodiment, combined Figure 1 and Figure 2 As shown, the front of each of the columns 4 is arranged in a trapezoidal shape to avoid a rigid collision between the end of the steel pipe and the column 4 during initial insertion.

[0022] In another embodiment, such as Figure 2 As shown, the wall panel 6 is a thickened wall panel 6 to ensure the strength of the wall panel 6.

[0023] In another embodiment, such as Figure 2 As shown, the guide groove 5 is a dovetail groove, and the shape of the guide protrusion 8 corresponds to the guide groove 5.

[0024] In another embodiment, such as Figure 3 As shown, the bottom front and rear ends of the cold drawing die 3 are respectively provided with chamfers to facilitate the insertion of the cold drawing die 3 between each column 4 and wall panel 6.

[0025] In another embodiment, such as Figure 2 As shown, the cold drawing seat 1 is fixed to the frame by two rows of fixing bolts.
