Description

Technical Field

[0001] This application relates to the field of spinning equipment, and particularly to a spinning equipment. Background Technology

[0002] Existing spinning equipment features a spinning wheel that feeds from back to front along a preset spinning trajectory, continuously spinning the tube blank to create a bottle neck and end cap that connect sequentially from back to front. However, when processing tube blanks with high hardness, such as stainless steel, the spinning wheel struggles to thicken the bottle neck due to material limitations such as insufficient plastic deformation capacity. This results in the bottle neck thickness often failing to meet product requirements. Furthermore, high-hardness tube blanks are prone to delamination cracks during the processing of end caps and bottle necks, reducing product safety. Utility Model Content

The displacement device is used to drive the rotating wheel to move relative to the rotary table in the front-back and left-right directions. The side of the rotating wheel close to the axis of the main shaft can abut against the outer circumference of the tube blank so that the rotating wheel can rotate with the tube blank and perform spinning processing on the outer circumference of the tube blank. Wherein: the displacement device can drive the rotating wheel to feed from back to front, and the rotating wheel is tilted forward on the side away from the axis of the main shaft.

[0005] In one exemplary embodiment, the outer surface of the spinning wheel includes a spinning section and a shaping section; The spinning section is formed between the outer peripheral wall of the spinning wheel and the front end face of the spinning wheel. The spinning section is an arc-shaped structure with the convex surface facing outward. The spinning section is used to spin the outer periphery of the tube blank. The shaping section is formed on the outer peripheral wall of the spinning wheel, and the shaping section is tangentially connected to the rear peripheral side of the spinning section. The radius of the shaping section is consistent along the axial direction.

[0006] In one exemplary embodiment, the central angle of the spun section is greater than 90°; and / or The axial width of the modified section is greater than 5 mm.

[0007] In one exemplary embodiment, the outer surface of the wheel includes an outer inclined section formed on the outer peripheral wall of the wheel, the outer inclined section being connected to the rear peripheral side of the shaping section, and the radius of the outer inclined section shrinking rearward along the axial direction; The angle between the outer inclined section and the axis of the wheel is 10°~20°.

[0008] In one exemplary embodiment, the front end face of the spinning wheel is recessed to form a clearance groove, and the spinning section is circumferentially connected to the outer periphery of the clearance groove; The spinning section is connected to the side of the clearance groove and fastens inward toward the center of the spinning wheel; The axial depth of the clearance groove is 8.5mm~11.5mm.

[0009] In an exemplary embodiment, the outer surface of the spinning wheel includes an inner inclined section formed on the outer annular sidewall of the clearance groove. One circumferential side of the inner inclined section is tangentially connected to the front circumferential side of the spinning section, and the other circumferential side of the inner inclined section extends to the bottom of the clearance groove. The radius of the inner inclined section tapers axially toward the bottom of the clearance groove. The angle between the inner inclined section and the axial end face of the wheel is not less than 10°; The radial width of the inner inclined section is 23mm~27mm.

[0010] In one exemplary embodiment, the axis of the rotating wheel and the axis of the main shaft are located in the same plane and are set at an angle; The angle between the axis of the rotating wheel and the axis of the main shaft is 5° to 7°.

[0011] In one exemplary embodiment, the rotating wheel includes at least two wheels arranged in a circumferential array around the axis of the main shaft.

[0012] In one exemplary embodiment, the displacement device includes a drive member and at least one rotating wheel seat disposed on the drive member. The drive member is used to drive the rotating wheel seat to move relative to the rotary table in the front-back and left-right directions. The rotating wheels are connected one-to-one to the rotating wheel seats, and the rotating wheel seats are used to adjust the angle between the axis of the rotating wheel and the axis of the main shaft.

[0013] In one exemplary embodiment, the rotating wheel seat includes a base, an adjusting seat, an adjusting screw, and an adjusting nut. The base is disposed on the driving member, the adjusting seat is rotatably connected to the base, the rotating wheel seat is disposed on the adjusting seat, one axial side of the adjusting screw is rotatably connected to the base about its axial direction, the adjusting nut is threadedly engaged with the other axial side of the adjusting screw, and the adjusting nut is connected to the adjusting seat. When the adjusting screw rotates relative to the base, the adjusting nut can move along the axial direction of the adjusting screw, thereby pushing the adjusting seat to rotate relative to the base.

[0014] The technical solutions provided by the embodiments of this application have at least the following beneficial effects: The spinning equipment disclosed in this application has a rotary table that can fix the tube blank and rotate it around its axial direction. A spinning wheel, driven by a displacement device, can abut against the outer circumference of the tube blank and move along the spinning trajectory. This allows the spinning wheel to rotate under the rotation of the tube blank and apply pressure, thus achieving spinning processing of the tube blank. The processed tube blank forms a bottle neck and a cap from back to front. By tilting the side of the spinning wheel away from the tube blank forward, i.e., tilting the side of the spinning wheel away from the tube blank towards the spinning feed direction, the spinning wheel applies forces to the tube blank simultaneously in both the axial feed direction and radially towards the tube blank during spinning processing. This ensures that the spinning wheel can apply radial extrusion pressure to the tube blank. For tube blanks with high hardness, the tilted spinning wheel can simultaneously extrude pressure at the bottle neck and cap positions during the spinning feed process, increasing the thickness of the bottle neck and cap while reducing the generation of interlayer cracks in the bottle neck and cap, thus improving product quality and safety.

[0028] Figure 1 A schematic diagram of a spinning processing equipment is shown. Figure 2 A schematic diagram of the spinning wheel 3 processing the tube blank 2 is shown. Figure 3 A schematic diagram of the spinning wheel 3 processing the tube blank 2 is shown.

[0029] Reference Figures 1 to 3 This application provides a spinning processing device, including a rotary table 1, a spinning wheel 3 and a displacement device.

[0030] The rotary table 1 includes a main shaft extending in the front-to-back direction. The rotary table 1 is used to position and rotate the tube blank 2 about the main shaft, and the axial direction of the tube blank 2 extends along the axis of the main shaft. The tube blank 2 can be positioned on the rotary table 1 and rotated along the axial direction of the tube blank 2 under the drive of the rotary table 1. The processed tube blank 2 can be removed from the rotary table 1.

[0031] The displacement device drives the spinning wheel 3 to move relative to the rotary table 1 in the front-back and left-right directions. The axis of the main shaft of the rotary table and the axial direction of the tube blank 2 both extend in the front-back direction. The left-right direction can be regarded as the radial direction relative to the main shaft and the tube blank 2, and is perpendicular to the front-back direction. The displacement device can drive the spinning wheel 3 to continuously spin the tube blank 2 from back to front according to the spinning trajectory. At the same time, the displacement device drives the spinning wheel 3 to move left and right to adjust the radial feed of the spinning wheel 3 to the tube blank 2, thereby spinning the tube blank 2 into a shape with a variable diameter along the axial direction. The processed tube blank 2 can present a bottle mouth 21, a cap 22 and a bottle body connected sequentially from back to front. The diameter of the bottle mouth 21 is smaller than the diameter of the bottle body, and the cap 22 has an arc surface structure and connects between the bottle mouth 21 and the bottle body.

[0032] The spinning wheel 3 is rotatably mounted on the displacement device along its axial direction, and is located on the radial side of the axis of the main shaft. The axis of the main shaft can be regarded as the rotation axis of the tube blank. During processing, the spinning wheel 3 is located on the radial side of the tube blank 2, and the side of the spinning wheel 3 close to the axis of the main shaft can abut against the outer circumference of the tube blank 2, so that the spinning wheel 3 can rotate with the tube blank 2 and perform spinning processing on the outer circumference of the tube blank 2.

[0033] Reference Figure 2 and Figure 3 The side of the spinning wheel 3 away from the axis of the main shaft is tilted forward, that is, the side of the spinning wheel 3 away from the tube blank 2 is tilted towards the direction of spinning feed. This allows the spinning wheel 3 to apply a component force along the axial feed direction and a radial force close to the tube blank 2 when spinning the surface of the tube blank 2. This ensures that the spinning wheel 3 can apply radial extrusion pressure to the tube blank 2. For tube blank 2 with high hardness, the tilted spinning wheel 3 can simultaneously extrude the bottle mouth 21 and the end cap 22 during the spinning feed process, thereby increasing the thickness of the bottle mouth 21 and the end cap 22, while reducing the generation of interlayer cracks in the bottle mouth 21 and the end cap 22, thus improving product quality and safety.

[0034] Furthermore, the axis of the spinning wheel 3 is located in the same plane as the axis of the main shaft and is set at an angle. When the displacement device drives the spinning wheel 3 to spin and feed the tube blank 2, the spinning wheel 3, which is inclined relative to the axis of the main shaft, can apply radial extrusion pressure to the tube blank 2. The inclined spinning wheel 3 can simultaneously extrude the bottle mouth 21 and the end cap 22 during the spinning and feeding process, thereby increasing the thickness of the bottle mouth 21 and the end cap 22.

[0035] Furthermore, such as Figure 2 As shown, the angle α between the axis of the spinning wheel 3 and the axis of the main shaft is 5°~7°.

[0036] The angle α between the axis of the rotating wheel 3 and the axis of the main shaft is set between 5° and 7°. This not only ensures that the rotating wheel 3 exerts radial extrusion pressure on the tube blank 2 during the feeding process, guaranteeing an increase in the thickness of the bottle neck 21, but also reduces interference with the tube blank 2. In practice, if the angle α between the axis of the rotating wheel 3 and the axis of the main shaft is less than 5°, the radial extrusion pressure on the tube blank 2 will be insufficient, resulting in an insufficient thickness of the bottle neck 21 for tube blanks with higher hardness. If the angle α between the axis of the rotating wheel 3 and the axis of the main shaft is greater than 7°, the rotating wheel 3 may be too tilted, causing interference with the end cap 22 of the tube blank 2, affecting product processing. In this application, the angle α between the axis of the rotating wheel 3 and the axis of the main shaft can be 6°.

[0037] Figure 4 A cross-sectional view of the structure of the spinning wheel 3 is shown.

[0038] Reference Figure 4 Furthermore, the outer surface of the spinning wheel 3 includes a spinning section 31 and a shaping section 32.

[0039] The spinning section 31 is formed between the outer peripheral wall of the spinning wheel 3 and the front end face of the spinning wheel 3. The spinning section 31 is an arc-shaped structure with the convex surface facing outward. The spinning section 31 is used to spin the outer periphery of the tube blank 2.

[0040] Specifically, the front side faces the spinning feed direction, and the rear side faces away from the spinning feed direction. That is, the front end face of the spinning wheel 3 is the end face of the spinning wheel 3 facing the spinning feed direction, and the rear end face of the spinning wheel 3 is the end face of the spinning wheel 3 facing away from the spinning feed direction. In this application, the side of the spinning wheel 3 away from the axis of the main shaft is tilted forward, and the convex arc surface of the spinning section 31 is formed between the end face of the spinning wheel 3 facing the feed direction and the outer peripheral side surface of the spinning wheel 3, ensuring that the spinning wheel 3 can abut against the arc surface and spin the tube blank 2, thereby improving the processing accuracy of the tube blank 2.

[0041] Furthermore, the central angle of the spinning section 31 is greater than 90°. The large arc range of the spinning section 31 allows the spinning wheel 3 to still contact the tube blank 2 with the convex arc surface of the spinning section 31 when processing the bottle mouth 21 and the end cap 22 of the tube blank 2, avoiding the spinning wheel 3 contacting the tube blank 2 with a sharp corner, reducing the generation of spiral marks, and facilitating the thickening of the bottle mouth 21.

[0042] In this embodiment, the radius of the spinning section 31 is 25mm, and the central angle is 105°~115°.

[0043] The shaping section 32 is formed on the outer peripheral wall of the spinning wheel 3, and is tangentially connected to the rear peripheral side of the spinning section 31. The shaping section 32 forms a continuous annular surface on the outer peripheral wall of the spinning wheel 3, and the radius of the shaping section 32 is consistent along the axial direction. Figure 4 As shown in the cross-sectional view, the extension direction of the shaping section 32 of the spinning wheel 3 is parallel to the axial direction of the spinning wheel 3. The shaping section 32 is connected to the side of the spinning section 31 facing away from the spinning feed direction. The shaping section 32 can further compress and shape the tube blank 2 after it has been spun by the spinning section 31, reducing the diameter tolerance of the bottle neck 21 and improving the processing accuracy of the tube blank 2. The shaping section 32 and the spinning section 31 are tangentially connected, avoiding the spinning wheel 3 from contacting the tube blank 2 with a sharp corner, reducing the generation of spiral marks, and facilitating the thickening of the bottle neck 21.

[0044] Furthermore, the axial width of the shaping section 32 is greater than 5mm. The axial extension length of the shaping section 32 needs to be greater than 5mm to ensure that it can perform the extrusion shaping function on the tube blank 2 part after being spun by the spinning section 31.

[0045] In fact, the shaping section 32 can also extend directly from the rear peripheral side of the spinning section 31 to the rear end face of the spinning wheel 3.

[0046] Furthermore, the outer surface of the wheel 3 includes an outer inclined section 33, which is formed on the outer peripheral wall of the wheel 3. The outer inclined section 33 is connected to the rear peripheral side of the shaping section 32, and the radius of the outer inclined section 33 shrinks rearward along the axial direction.

[0047] Specifically, the spinning section 31, the shaping section 32 and the outer inclined section 33 on the outer surface of the spinning wheel 3 are connected in sequence along the opposite spinning feed direction. The outer inclined section 33 extends to the rear end face of the spinning wheel 3. The radius of the outer inclined section 33 shrinks in the axial direction away from the shaping section 32, which can avoid the surface of the tube blank 2 and reduce the weight of the spinning wheel 3.

[0048] In this embodiment, the outer inclined section 33 and the shaping section 32 are connected tangentially by an arc surface to reduce the sharp corners of the outer peripheral wall of the wheel 3. In addition, the angle between the outer inclined section 33 and the axis of the wheel 3 is 10°~20°.

[0049] Because the side of the spinning wheel 3 away from the axis of the main shaft is tilted forward, the spinning wheel 3 will have an angle with the surface of the tube blank 2. When the spinning wheel 3 spins the tube blank 2, the front end face of the spinning wheel 3 may interfere with the connection between the bottle mouth 21 and the end cap 22 of the tube blank 2.

[0050] Combination Figure 2 and Figure 4In this embodiment, the front end face of the spinning wheel 3 is recessed to form a relief groove 34, and the spinning section 31 is circumferentially connected to the outer periphery of the relief groove 34. In this embodiment, by forming a relief groove 34 recessed on the front end face of the spinning wheel 3 facing the spinning feed direction, and at the same time connecting the outer periphery of the relief groove 34 with the spinning section 31, the relief groove 34 can avoid the outer surface of the tube blank 2 when the spinning wheel 3 is processing the tube blank 2, thereby reducing interference between the spinning wheel 3 and the tube blank 2.

[0051] Furthermore, the front end face of the rotary wheel 3 is provided with an avoidance groove 34, which allows the rear trajectory of each rotary wheel 3 to follow an arc without interference, thereby increasing the thickness of the bottle mouth 21 and the sealing head 22.

[0052] Furthermore, the spinning section 31 is connected to the side of the relief groove 34 and bends inward toward the center of the spinning wheel 3. The spinning section 31 bends inward to ensure that the spinning wheel 3 can contact the end cap 22 of the tube blank 2 with a complete arc surface, thereby improving the processing effect.

[0053] Furthermore, the axial depth of the clearance groove 34 is 8.5mm~11.5mm. The clearance groove 34 has a certain depth, which allows the spinning wheel 3 to avoid the outer surface of the tube blank 2, and the depth of the clearance groove 34 is greater than 8.5mm, ensuring the rigidity and strength of the spinning wheel 3 structure.

[0054] Furthermore, the outer surface of the spinning wheel 3 includes an inner inclined section 341, which is formed on the outer ring sidewall of the clearance groove 34. One circumference of the inner inclined section 341 is tangentially connected to the front circumference of the spinning section 31, and the other circumference of the inner inclined section 341 extends to the bottom of the clearance groove 34. The radius of the inner inclined section 341 tapers axially toward the bottom of the clearance groove 34. The inner inclined section 341 extends obliquely backward from the front circumference of the spinning section 31 to the bottom of the clearance groove 34, which can avoid the outer surface of the tube blank 2 and ensure the structural strength of the spinning section 31.

[0055] Furthermore, such as Figure 4 As shown, the angle b between the inner inclined section 341 and the axial end face of the spinning wheel 3 is not less than 10°, to prevent the angle b between the inner inclined section 341 and the axial end face of the spinning wheel 3 from being too small and causing scraping of the tube blank 2 surface, thus ensuring the avoidance function.

[0056] Furthermore, the radial width of the inner bevel section 341 is 23mm~27mm. Specifically, the radial distance between the bottom of the clearance groove 34 and the spinning section 31 is maintained at 23mm~27mm. That is, the bottom of the clearance groove 34 and the side of the spinning section 31 away from the shaping section 32 have a certain distance in the radial direction of the spinning wheel 3, and the spinning section 31 is located on the outer periphery of the clearance groove 34, so that the inner bevel section 341 can extend inward to a sufficient depth to achieve the effect of clearing the tube blank 2. At the same time, the spinning wheel 3 needs to be rotatably connected to the displacement device in the middle of the clearance groove 34. The radial width of the inner bevel section 341 is less than 27mm, which can reserve enough space for the installation of the spinning wheel 3. It should be noted that the installation structure of the spinning wheel 3 in the middle of the clearance groove 34 needs to be located inside the front end face of the spinning wheel 3 to avoid interference between the installation structure and the tube blank 2.

[0057] In some other embodiments, the spun section 31 may also be curved inward and extend to the bottom of the relief groove 34, with the inward portion of the spun section 31 forming the outer ring sidewall of the relief groove 34.

[0058] When the tube blank 2 is made of a material with high hardness, the spinning wheel 3 includes at least two wheels, which are arranged circumferentially around the axis of the main shaft. For details, refer to... Figure 1 and Figure 2 The tube blank 2 is made of stainless steel. The spinning equipment includes two spinning wheels 3, which are located on opposite sides of the axis of the main shaft. A displacement device can simultaneously drive both spinning wheels 3 to perform synchronous spinning on the tube blank 2, enabling the processing of materials with high hardness. In some other embodiments, if the tube blank 2 is made of a softer material, such as aluminum, the spinning equipment may only have one spinning wheel 3. Furthermore, the number of spinning wheels 3 can be increased depending on the hardness of the material selected for the tube blank 2. Multiple spinning wheels 3 are arranged in a circumferential array around the axis of the main shaft, meaning that the spacing between adjacent spinning wheels 3 is consistent, improving the uniformity of force distribution on the tube blank 2.

[0059] Figure 5 A schematic diagram of the structure of the rotating wheel 3 and the rotating wheel seat 5 is shown.

[0060] Combination Figure 1 and Figure 5 The displacement device includes a drive member 4 and at least one rotating wheel seat 5 disposed on the drive member 4. The drive member 4 is used to drive the rotating wheel seat 5 to move relative to the rotary table 1 in the front-back and left-right directions. The rotating wheels 3 are connected one-to-one to the rotating wheel seat 5. The rotating wheel seat 5 is used to adjust the angle between the axial direction of the rotating wheel 3 and the axis of the main shaft.

[0061] Specifically, the driving component 4 can be a combination of hydraulic cylinders or a combination of motors, capable of driving the rotary seat to move relative to the rotary table 1 in the forward and backward and left and right directions. In this embodiment, the driving component 4 uses a servo motor, which controls the displacement of the rotary wheel seat 5 to improve the accuracy of operation. Furthermore, when using two rotary wheels 3 to simultaneously spin-process the tube blank 2, the servo motor can precisely control the movement of the two rotary wheel seats 5 through dual-axis linkage, achieving consistency in product processing and providing automatic control precision.

[0062] Furthermore, the spinning wheel seat 5 can be used to adjust the angle α between the axis of the spinning wheel 3 and the axis of the main shaft. This allows operators to adjust the angle α between the axis of the spinning wheel 3 and the axis of the main shaft according to different blank materials 2 and different spinning trajectories, thereby improving processing accuracy and broadening its applicability. In some other embodiments, if only processing of the same type of product is required, the angle α between the axis of the spinning wheel 3 and the axis of the main shaft can be fixed and does not need adjustment.

[0063] Furthermore, the rotating wheel seat 5 includes a base 51, an adjusting seat 52, an adjusting screw 53, and an adjusting nut. The base 51 is mounted on the driving member 4, the adjusting seat 52 is rotatably connected to the base 51, the rotating wheel seat 5 is mounted on the adjusting seat 52, one axial side of the adjusting screw 53 is rotatably connected to the base 51 around its axial direction, the adjusting nut is threadedly engaged with the other axial side of the adjusting screw 53, and the adjusting nut is connected to the adjusting seat 52.

[0064] Specifically, the axis of rotation of the adjusting seat 52 is perpendicular to both the front-back and left-right directions in space. The adjusting screw 53 is axially rotatably connected to the base 51 via a bearing or other rotating seat. When the adjusting screw 53 rotates relative to the base 51, the adjusting nut can move along the axis of the adjusting screw 53, thereby causing the adjusting nut to push the adjusting seat 52 to rotate relative to the base 51, so as to realize the tilting swing of the rotating wheel 3 relative to the tube blank 2 and improve the angle adjustment accuracy of the rotating wheel 3.

[0065] The spinning processing equipment of this application processes the stainless steel tube blank 2 in the following steps: Two rotating wheels 3 are installed on the displacement device, and the tilt angle of the two rotating wheels 3 relative to the axis of the main shaft of the rotary table 1 is adjusted. The two rotating wheels 3 are respectively located on the left and right sides of the axis of the main shaft, and the two rotating wheels 3 are symmetrically arranged with the axis of the main shaft as the center.

[0066] The stainless steel tube blank 2 is fed into the spindle of the rotary table 1 by a crane and the tube blank 2 is clamped.

[0067] Mark the heating area of ​​tube blank 2, start the medium frequency furnace motor to move the medium frequency furnace to the marked area of ​​tube blank 2, and start heating the stainless steel tube blank.

[0068] Once the billet temperature reaches 900~1100℃, start the medium-frequency furnace motor and move it to the tail end.

[0069] The spinning program is initiated, at which point both spinning wheels 3 simultaneously begin axial movement according to the program. Due to the high hardness of the tube blank 2 material, the rotational speed of the rotary table 1 spindle needs to be set between 200 r / min and 300 r / min in the program. The displacement device controls the spinning wheels 3 to spin the tube blank 2 along the spinning trajectory. The inclined spinning wheels 3 can compress the bottle mouth 21 and end cap 22 in the feed direction and radial direction during the spinning feed process, thereby increasing the thickness of the bottle mouth and end cap, while reducing the generation of interlayer cracks in the bottle mouth and end cap, improving product quality and safety. Moreover, the spinning trajectory of each spinning wheel 3 controlled by the displacement device has a straight section at the beginning and a circular arc section at the end, which can further thicken the bottle mouth 21 and end cap 22 of the tube blank 2.
