Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to a gas cylinder ejection device and a hydraulic press. Background Technology

[0002] After the gas cylinder parts are stretched and formed by a hydraulic press, the formed parts need to be unloaded from the stretching punch.

[0003] In current production, manual labor is often used in conjunction with a ejector fork to complete the ejection process. During operation, the operator holds the ejector fork, aligns it with the end of the cylinder, and uses external force to peel the cylinder off the reset punch.

[0004] This method relies on manual operation. In mass production, workers repeatedly perform actions such as alignment and unloading, which is labor-intensive and slow in the material return process. Meanwhile, manual alignment carries a significant risk of positional deviation. The ejector fork is prone to shifting from the center of the cylinder. The rigid fork body of the ejector fork directly contacts the opening of the cylinder, which can easily scratch or damage the cylinder's opening, resulting in defects in the cylinder's appearance and shape. Utility Model Content

[0006] Therefore, this utility model provides a gas cylinder component unloading device; The second aspect of this utility model provides a hydraulic press.

[0007] In view of this, the first aspect of this utility model provides a gas cylinder unloading device, including a disc base, a slider, a roller assembly, a limiting assembly, and a reset assembly.

[0008] A first through hole is provided at the center of the disc base along the axial direction, and a receiving groove is provided in the radial direction of the disc base, with one end of the receiving groove connected to the first through hole; a slider is slidably assembled in the receiving groove for blocking the cylindrical part; a roller assembly is installed at the end of the slider near the first through hole for contacting the cylindrical part; a limiting assembly is installed on the circumferential side of the disc base and is connected to the end of the slider away from the first through hole; a reset assembly is installed on the circumferential side of the disc base and abuts against the end of the slider away from the first through hole.

[0009] The gas cylinder unloading device proposed in this utility model, through the cooperation of a disc base, a slider, a roller assembly, a limiting assembly, and a resetting assembly, enables the slider to slide radially along the receiving groove. The limiting assembly constrains the slider's movement trajectory, the resetting assembly provides elastic clamping force, and the roller assembly is used to roll and contact the cylinder to avoid scratching it. When the punch returns, the slider's blocking action enables the unloading of the cylinder, eliminating manual operation, reducing labor intensity, improving unloading efficiency, and ensuring stable and reliable unloading operations.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0016] Please see Figures 1 to 8 A gas cylinder ejection device and a hydraulic press are provided, including a disc base 100, a slider 200, a roller assembly 300, a limiting assembly 400, and a reset assembly 500. The disc base 100 has a first through hole 110 axially formed at its center, and a receiving groove 120 radially formed therefrom, one end of which communicates with the first through hole 110. The slider 200 is slidably mounted in the receiving groove 120 for receiving the cylinder. The roller assembly 300 is mounted on the end of the slider 200 near the first through hole 110 for contacting the cylinder. The limiting assembly 400 is mounted on the circumferential side of the disc base 100 and connected to the end of the slider 200 away from the first through hole 110. The reset assembly 500 is mounted on the circumferential side of the disc base 100 and abuts against the end of the slider 200 away from the first through hole 110.

[0017] In this embodiment: the gas cylinder unloading device and hydraulic press include a disc base 100, a slider 200, a roller assembly 300, a limiting assembly 400, and a reset assembly 500.

[0018] A first through hole 110 is provided at the center of the disc base 100 along the axial direction, and a receiving groove 120 is provided in the disc base 100 along the radial direction. One end of the receiving groove 120 is connected to the first through hole 110. The first through hole 110 is for the passage of the cylindrical part, and the radially opened receiving groove 120 serves as the sliding cavity of the slider 200.

[0019] The slider 200 is slidably assembled in the receiving groove 120; the slider 200 can extend into and retract along the receiving groove 120 to the first through hole 110. When the stretching punch returns, the slider 200 extending into the first through hole 110 is used to block the cylinder, thereby separating the punch and the cylinder and realizing material removal.

[0020] The roller assembly 300 is installed at the end of the slider 200 near the first through hole 110 and is used to contact the cylinder. During operation, the roller assembly 300 directly rolls in contact with the outer wall of the cylinder to avoid scratching the outer surface of the cylinder, while also providing support for the cylinder.

[0021] The limiting component 400 is installed on the circumferential side of the base 100 and is connected to the end of the slider 200 away from the first through hole 110. The limiting component 400 is used to stabilize the radial movement trajectory of the slider 200, prevent the slider 200 from shifting in the receiving groove 120, and limit the extension stroke of the slider 200. It can adjust the depth of the slider 200 into the first through hole 110 according to the specifications of the cylindrical part, and has strong adaptability.

[0022] The reset assembly 500 is installed on the circumferential side of the base 100 and abuts against the end of the slider 200 away from the first through hole 110. When the cylinder passes through the first through hole 110 and pushes the slider 200 outward, the reset assembly 500 provides an elastic thrust to push the slider 200 back toward the first through hole 110, so that the roller assembly 300 can contact the cylinder and the slider 200 can block the cylinder.

[0023] Please see Figure 2 In some embodiments of this utility model, optionally, the number of sliders 200 is 3 to 6, and the 3 to 6 sliders 200 are distributed around the first through hole 110.

[0024] In this embodiment, the number of sliders 200 is 3 to 6, and the 3 to 6 sliders 200 are distributed around the first through hole 110; optionally, there are 4 sliders 200. The 4 sliders 200 can apply force to the gas cylinder component from multiple directions at the same time, and the force is uniform, avoiding deformation of the cylinder component under pressure on one side. It can be adapted to different cylinder component diameters, and together with the roller assembly 300, it can stably clamp the cylinder component, ensuring a smooth and reliable unloading operation.

[0025] Please see Figure 4 and Figure 5 In some embodiments of this utility model, optionally, a second through hole 130 is provided on the circumferential side of the disk base 100, and the second through hole 130 communicates with the receiving groove 120. The limiting component 400 includes a screw 410 and a first nut 420. The screw 410 passes through the second through hole 130, and one end of the screw 410 extending into the receiving groove 120 is installed on the slider 200; the first nut 420 is screwed to the end of the screw 410 extending out of the disk base 100.

[0026] In this embodiment: a second through hole 130 is provided on the circumferential side of the disc base 100, the second through hole 130 is connected to the receiving groove 120, and the limiting component 400 includes a screw 410 and a first nut 420.

[0027] The screw 410 passes through the second through hole 130, and one end of the screw 410 that extends into the receiving groove 120 is installed on the slider 200; the screw 410 can reciprocate with the slider 200 in the second through hole 130.

[0028] The first nut 420 is screwed to one end of the screw 410 that extends out of the disc base 100. When the slider 200 extends into the first through hole 110 to its limit position, the first nut 420 abuts against the outer circumference of the disc base 100. The first nut 420 can be adjusted along the axial direction of the screw 410 by screwing, which limits the limit position of the slider 200 extending into the first through hole 110, thereby adapting to cylindrical parts with different outer diameters.

[0029] Please see Figure 5 In some embodiments of this utility model, optionally, the number of first nuts 420 is 2 or 3, and adjacent first nuts 420 in the 2 or 3 first nuts 420 are abutted together.

[0030] In this embodiment: the number of first nuts 420 is 2 or 3, and the two or three first nuts 420 are arranged in abutting position; by using the principle of multi-nut top locking, the position of the first nuts 420 can be locked to prevent the first nuts 420 from loosening and shifting, and to ensure the stability of limiting the slider 200.

[0031] Please see Figure 4 and Figure 6 In some embodiments of this utility model, optionally, a blind hole 210 is provided at the end of the slider 200 away from the first through hole 110, and a first screw hole 140 is provided on the circumferential side of the disk base 100. The first screw hole 140 communicates with the receiving groove 120. The blind hole 210 and the first screw hole 140 are axially aligned. The reset assembly 500 includes a pin 510, a spring 520, a screw 530, and a second nut 540. The pin 510 includes a pin body and a cap body. The pin body is slidably fitted into the blind hole 210. The spring 520 is sleeved on the pin body. One end of the spring 520 abuts against the end of the blind hole 210, and the other end of the spring 520 abuts against the cap body. The screw 530 is screwed into the first screw hole 140. One end of the screw 530 extends into the receiving groove 120 and abuts against the pin 510. The second nut 540 is screwed into the screw 530 and abuts against the outer circumference of the disk base 100.

[0032] In this embodiment: a blind hole 210 is provided at the end of the slider 200 away from the first through hole 110, and a first screw hole 140 is provided on the circumferential side of the disk base 100. The first screw hole 140 is connected to the receiving groove 120, and the blind hole 210 is axially aligned with the first screw hole 140. The blind hole 210 provides an installation position for the reset assembly 500.

[0033] The reset assembly 500 includes a pin 510, a spring 520, a screw 530, and a second nut 540.

[0034] The pin 510 includes a pin body and a cap body, which are integrally formed. The pin body is slidably assembled into the blind hole 210.

[0035] Spring 520 is sleeved on the nail body, with one end of spring 520 abutting the end of blind hole 210 and the other end of spring 520 abutting the cap body; slider 200 can reciprocate relative to pin 510. When slider 200 is pushed open by the cylinder, spring 520 between blind hole 210 and cap body is compressed to store force. After the cylinder passes, spring 520 extends and resets, pushing slider 200 away from the cap body, thus completing the reset of slider 200.

[0036] Screw 530 is screwed into the first screw hole 140, and one end of screw 530 extends into the receiving groove 120 and abuts against pin 510. By screwing screw 530 screwed into the first screw hole 140, the insertion depth of screw 530 can be changed, thereby adjusting the pre-compression of spring 520 and changing the magnitude of the reset spring force of slider 200 to adapt to the blocking requirements of different specifications of cylindrical parts.

[0037] The second nut 540 is screwed onto the screw 530 and abuts against the outer circumference of the disc base 100. After adjusting the position of the screw 530, tighten the second nut 540 and abut against the outer circumference of the disc base 100 to lock the screw 530's screw depth, prevent vibration from causing the screw 530 to rotate and loosen, and ensure the stability of the spring 520's preload. The second nut 540 plays a role in locking and preventing loosening.

[0038] Please see Figure 4 In some embodiments of this utility model, optionally, each slider 200 abuts against two reset components 500, and the two reset components 500 are symmetrically arranged on both sides of the limiting component 400.

[0039] In this embodiment: each slider 200 abuts against two reset components 500, and the two reset components 500 are symmetrically arranged on both sides of the limiting component 400; the symmetrical arrangement of the two reset components 500 can make the slider 200 bear the force evenly, avoid the bias and jamming caused by the force on one side, ensure that the slider 200 slides smoothly along the receiving groove 120, and improve the stability of the movement of the slider 200.

[0040] Please see Figure 7 In some embodiments of this utility model, optionally, the slider 200 has a stepped hole 220, which is perpendicular to the blind hole 210. The roller assembly 300 includes a stepped screw 310, a roller 320, and a third nut 330. The stepped screw 310 passes through the stepped hole 220; the roller 320 is rotatably mounted on the stepped screw 310; the third nut 330 is screwed onto the stepped screw 310 and is located inside the stepped hole 220.

[0041] In this embodiment: the slider 200 has a stepped hole 220, which is perpendicular to the blind hole 210. The stepped hole 220 provides an installation position for the roller assembly 300.

[0042] The roller assembly 300 includes a stepped screw 310, a roller 320, and a third nut 330.

[0043] The stepped screw 310 passes through the stepped hole 220; the stepped structure of the stepped screw 310 and the stepped hole 220 can achieve axial positioning to facilitate assembly. The stepped screw 310 serves as the rotation support shaft of the roller 320, limiting the assembly position of the roller 320 and ensuring that the roller 320 can rotate around the stepped screw 310.

[0044] Roller 320 is rotatably mounted on stepped screw 310; when the cylinder passes through the first through hole 110, roller 320 rolls along the outer wall of the cylinder, changing the original sliding friction into rolling friction, reducing contact wear, and ensuring that the surface of the cylinder is not scratched.

[0045] The third nut 330 is screwed onto the stepped screw 310 and is located inside the stepped hole 220. The third nut 330 is used to lock the stepped screw 310, prevent the stepped screw 310 from loosening and shifting, maintain the assembly reliability of the roller 320, and the third nut 330 does not occupy external space.

[0046] Please see Figure 7 In some embodiments of this utility model, optionally, a groove 600 is provided at the end of the slider 200 away from the blind hole 210, and the side of the roller 320 away from the blind hole 210 extends out of the groove 600.

[0047] In this embodiment: a groove 600 is provided at the end of the slider 200 away from the blind hole 210, and the side of the roller 320 away from the blind hole 210 extends out of the groove 600; the groove 600 plays a role in avoiding collisions, making it easier for the roller 320 to contact the cylinder, preventing the slider 200 from bumping and scratching the outer wall of the cylinder, and maximizing the area of ​​the slider 200 blocking the cylinder to ensure reliable blocking.

[0048] Please see Figure 8 In some embodiments of this utility model, optionally, the disc base 100 has a third through hole 150, and the number of third through holes 150 is at least four. At least four third through holes 150 are distributed around the first through hole 110. The gas cylinder unloading device also includes a flange 700. The flange 700 is installed on the disc base 100, and the flange 700 has a fourth through hole 710, which is axially aligned with the third through holes 150.

[0049] In this embodiment: the plate base 100 is provided with a third through hole 150, and the number of third through holes 150 is at least 4. At least four third through holes 150 are distributed around the first through hole 110. The gas cylinder component unloading device also includes a flange 700.

[0050] Flange 700 is installed on plate base 100. Optionally, flange 700 is installed on plate base 100 by means of screw connection. Accordingly, flange 700 has countersunk hole and plate base 100 has threaded blind hole. The connecting screw passes through countersunk hole and is screwed into threaded blind hole, thereby fastening flange 700 to plate base 100, sealing receiving groove 120 and protecting internal structure.

[0051] Furthermore, three to six connecting screws are distributed around the first through hole 110 to ensure a secure installation.

[0052] The flange 700 has a fourth through hole 710, which is axially aligned with the third through hole 150. The aligned fourth through hole 710 and the third through hole 150 facilitate the passage of fastening screws, making it easy to install the entire gas cylinder unloading device on the stretching table adapted to the hydraulic press, and also making disassembly convenient.

[0053] A hydraulic press includes the aforementioned gas cylinder unloading device.

[0054] The fastening screws fix the gas cylinder ejection device to the stretching table adapted to the hydraulic press through the aligned fourth through hole 710 and third through hole 150. The first through hole 110 of the plate 100 is aligned with the center of the stretching die.

[0055] During debugging, rotate screw 530 to adjust the preload of spring 520, and rotate screw 410 in conjunction with first nut 420 to limit the maximum extension stroke of slider 200 to match the outer diameter of the gas cylinder part to be processed.

[0056] The hydraulic press's stretching punch drives the gas cylinder through the stretching die and into the first through hole 110. The outer wall of the cylinder pushes the roller 320 outward, driving the slider 200 to slide outward along the receiving groove 120 and compress the spring 520. When the cylinder stretching is complete, the spring 520 continues to push the slider 200, and the roller 320 moves along the contacted outer wall of the cylinder until it contacts the stretching punch. When the stretching punch returns, the slider 200 blocks the end of the cylinder, peeling the cylinder off the stretching punch to complete the unloading. After the stretching punch resets and disengages from the roller 320, the slider 200 resets to its initial position for the next unloading.
