Description

Technical Field

[0001] This application relates to the technical field of seamless steel pipe processing equipment, and in particular to a cold drawing production apparatus for seamless stainless steel pipes. Background Technology

[0002] Seamless stainless steel pipes have a hollow cross section and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water, and certain solid materials. During cold drawing, the steel pipe undergoes plastic deformation under the tensile force of a tensile testing machine as it passes through a mold of a certain shape and size.

[0003] Regarding the aforementioned technologies, the applicant believes that currently, in the cold drawing process, it is generally not possible to position and support steel pipes of different sizes and specifications. Different fixing devices need to be replaced to position the steel pipes, which reduces the processing efficiency in practical applications, and there is still room for improvement. Utility Model Content

[0004] In order to enable cold drawing equipment to meet the positioning and support requirements of stainless steel tubes of different sizes and specifications and improve the processing efficiency in practical applications, this application provides a seamless stainless steel tube cold drawing production device.

[0005] The seamless stainless steel tube cold drawing production apparatus provided in this application adopts the following technical solution: A seamless stainless steel tube cold drawing production apparatus includes a support base for supporting the stainless steel tube. The support bases are arranged opposite each other and include an extrusion seat and a base. A tube seat that abuts against the side wall of the stainless steel tube is rotatably connected to the extrusion seat. The opposite bases can move towards each other. The extrusion seat is lifted and connected to the base via a movable structure. The movable structure includes a drive plate and a drive motor. One end of the drive plate is rotatably connected to the side wall of the base. An inclined lifting groove is opened on the side wall of the extrusion seat for the other end of the drive plate to slide. The drive motor is fixed to the base, and the output shaft of the drive motor is fixed to the corresponding end of the drive plate. The drive plate moves along the lifting groove to drive the extrusion seat to rise and fall. The extrusion seat is positioned by the fixed structure.

[0006] By adopting the above technical solution, on the one hand, the relative lateral distance between the extrusion seats is adjusted by the opposing bases; on the other hand, when the drive motor controls the drive plate to slide along the lifting groove, the extrusion seat can be driven to rise relative to the base. Furthermore, by fixing the structure for positioning, the height of the extrusion seat and the tube seat can be adjusted, so that the cold drawing equipment can meet the positioning support of stainless steel tubes of different sizes and specifications obtained after cold drawing, thereby improving the processing efficiency of practical applications.

[0007] Preferably, the lifting groove extends upward at an angle from one side of the extrusion seat toward the center of the extrusion seat, and the straight-line distance between the rotating end of the drive plate and the end of the lifting groove located in the center of the extrusion seat is less than the diameter of the drive plate.

[0008] By adopting the above technical solution, the straight-line distance between the rotating end of the drive plate and the end of the lifting groove located in the middle of the extrusion seat is less than the diameter of the drive plate. When the drive plate slides along the lifting groove, it can drive the extrusion seat to rise and fall relative to the base, adjust the height of the extrusion seat, and is suitable for stainless steel tubes of different sizes after cold drawing.

[0009] Preferably, the fixing structure includes a fixing plate and fixing bolts. The fixing plate is fixed to the outside of the side wall of the extrusion seat and extends downward to the side wall of the base. When the extrusion seat rises, the fixing bolts are fixed to the corresponding positions of the fixing plate and the base.

[0010] By adopting the above technical solution, when the extrusion seat rises relative to the base, it can be connected to the base through a fixing plate and locked by fixing bolts, thereby improving the structural stability after rising.

[0011] Preferably, the drive plates are disposed opposite each other on both sides of the base, and the lifting grooves are respectively opened on the opposite side walls of the base for the corresponding drive plates to slide; the opposite drive plates on the extrusion seat are fixedly connected by a connecting shaft.

[0012] By adopting the above technical solution, the drive plates on the opposite extrusion seats are synchronously driven through the connection of the connecting shaft, so that the opposite drive plates are synchronously driven under the drive of the connecting shaft, thereby making the lifting and lowering of the opposite extrusion seats more synchronous.

[0013] Preferably, the base is supported by a positioning seat, and a slider is fixed at the bottom of the base. The positioning seat has a sliding groove for the slider to slide. A control screw is inserted into the opposite base. The two ends of the control screw are rotatably connected to the corresponding positions of the positioning seat, and one end of the control screw is driven by a control motor fixed on the positioning seat. The control screw has a reverse thread, and the reverse threads are threaded to the opposite base.

[0014] By adopting the above technical solution, the horizontal movement of the relative base is guided by the cooperation of the slider and the sliding groove. The rotation of the control screw can drive the relative base to move towards or away from each other, and adjust the distance between the relative extrusion seat and the tube seat. It is suitable for stainless steel tubes of different sizes after cold drawing.

[0015] Preferably, the compression seat is connected to the base via a guide structure.

[0016] Preferably, the guide structure includes a guide post and a guide groove. The guide post is fixed to the lower part of the extrusion seat, and the guide groove is opened on the base for the guide post to be inserted into.

[0017] By adopting the above technical solution, the guide extrusion seat can be stably raised and lowered relative to the base with the cooperation of the guide column and the guide groove.

[0018] In summary, this application includes at least one of the following beneficial technical effects: On the one hand, the relative lateral distance between the extrusion seats is adjusted by the opposing bases. On the other hand, when the drive motor controls the drive plate to slide along the lifting groove, it can drive the extrusion seat to rise relative to the base. Furthermore, the height of the extrusion seat and the tube seat is adjusted by the fixed structure positioning, so that the cold drawing equipment can meet the positioning support of stainless steel tubes of different sizes and specifications obtained after cold drawing, thereby improving the processing efficiency of practical applications. The straight-line distance between the rotating end of the drive plate and the end of the lifting groove located in the middle of the extrusion seat is less than the diameter of the drive plate. When the drive plate slides along the lifting groove, it can drive the extrusion seat to rise and fall relative to the base, adjust the height of the extrusion seat, and is suitable for stainless steel tubes of different sizes after cold drawing. The horizontal movement of the relative base is guided by the cooperation of the slider and the sliding groove. The rotation of the control screw can drive the relative base to move towards or away from each other, adjusting the distance between the relative extrusion seat and the tube seat. It is suitable for stainless steel tubes of different sizes after cold drawing. Attached Figure Description

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application discloses a seamless stainless steel tube cold drawing production apparatus, referring to... Figure 1 The system includes a support seat 1 for supporting the steel pipe, the support seats 1 are arranged opposite to each other, and include an extrusion seat 2 and a base 3. The extrusion seat 2 is located above the base 3, and the upper part of the extrusion seat 2 is rotatably connected to a pipe seat 21 that abuts against the side wall of the stainless steel pipe. The side wall of the pipe seat 21 is arc-shaped and can cooperate with the side wall of the stainless steel pipe.

[0023] Reference Figure 1The extrusion seat 2 is connected to the base 3 via a guide structure 4. The guide structure 4 includes a guide post 41 and a guide groove 42. The guide post 41 is fixed to the lower part of the extrusion seat 2, and the guide groove 42 is opened on the base 3 for the guide post 41 to be inserted into. With the cooperation of the guide post 41 and the guide groove 42, the extrusion seat 2 is guided to rise and fall stably relative to the base 3.

[0024] Reference Figure 1 The extrusion seat 2 is connected to the base 3 via a movable structure 5. The movable structure 5 includes a drive plate 51 and a drive motor 52. One end of the drive plate 51 is rotatably connected to the side wall of the base 3, and the other end is connected to the extrusion seat 2. The drive motor 52 is fixed to the base 3, and the output shaft of the drive motor 52 is fixed to the corresponding end of the drive plate 51.

The straight distance between the rotating end of the drive plate 51 and the end of the lifting groove 22 located in the middle of the extrusion seat 2 is less than the diameter of the drive plate 51. When the drive plate 51 slides along the lifting groove 22, it can drive the extrusion seat 2 to rise and fall relative to the base 3, adjust the height of the extrusion seat 2, and make it suitable for stainless steel pipes of different sizes. It should be noted that the power of the drive plate 51 moving along the lifting groove 22 is sufficient to overcome the gravity of the extrusion seat 2 and the pipe seat 21, and drive the extrusion seat 2 and the pipe seat 21 to rise.

[0026] Reference Figure 1 , 3 The drive plates 51 are disposed opposite each other on both sides of the base 3, and the lifting grooves 22 are respectively opened on the opposite side walls of the base 3 for the corresponding drive plates 51 to slide. The opposite drive plates 51 on the same extrusion seat 2 are fixedly connected by the connecting shaft 6, so that the opposite drive plates 51 are driven synchronously under the drive of the connecting shaft 6, thereby making the lifting and lowering of the opposite extrusion seats 2 more synchronous. It should be noted that the drive motors 52 on the opposite extrusion seats 2 are synchronized by the synchronizer to improve the synchronicity of the lifting and lowering of the opposite extrusion seats 2.

[0027] Reference Figure 1 , 2 The drive plate 51 moves along the lifting groove 22 to drive the extrusion seat 2 to rise and fall. The extrusion seat 2 is positioned by the fixing structure 7. The fixing structure 7 includes a fixing plate 71 and fixing bolts 72. The fixing plate 71 is fixed to the outside of the side wall of the extrusion seat 2 and extends downward to the side wall of the base 3. When the extrusion seat 2 rises, the fixing bolts 72 are fixed to the lower part of the fixing plate 71 at the corresponding position of the base 3. When the extrusion seat 2 rises relative to the base 3, the lower part of the fixing plate 71 always corresponds to the base 3. The fixing plate 71 is connected to the base 3 and locked by the fixing bolts 72, which improves the structural stability after rising.

[0028] Reference Figure 1 , 3 The opposing bases 3 can move towards each other; the base 3 is supported by the positioning seat 8, and the support plate 11 is located on the upper part of the positioning seat 8, which does not obstruct the movement of the base 3; a slider 31 is fixed at the bottom of the base 3, and a sliding groove 81 is provided on the positioning seat 8 for the slider 31 to slide; a control screw 9 is inserted inside the opposing base 3, and the two ends of the control screw 9 are respectively rotatably connected to the corresponding positions of the positioning seat 8, and one end of the control screw 9 is driven by the control motor 10 fixed on the positioning seat 8; the control screw 9 is provided with a reverse thread, and the reverse thread is respectively threaded to the opposing base 3, and the control motor 10 drives the control screw 9 to rotate, so that the opposing bases 3 can move towards or away from each other; the horizontal movement of the opposing bases 3 is guided by the cooperation of the slider 31 and the sliding groove 81, and the rotation of the control screw 9 can drive the opposing bases 3 to move towards or away from each other, adjusting the distance between the opposing extrusion seat 2 and the tube seat 21, which is suitable for positioning and supporting stainless steel tubes of different sizes and specifications obtained after cold drawing.
