Description

Technical Field

[0001] The invention relates to the technical field of gas spring processing equipment, and in particular to a double-station gas spring cylinder closing and forming equipment. Background Art

[0002] As a common pneumatic component, gas springs are widely used in various industries and are well known to people. Gas springs need to go through multiple processes during production, including sealing the gas spring tube mouth, drilling holes at the seal, and welding plugs. The traditional gas spring tube mouth sealing method is to use hot extrusion to seal the gas spring tube end, but the thickness of the tube end after hot extrusion sealing is relatively thin. After drilling and welding plugs at the drilled holes in the later stage, it is impossible to effectively ensure the coaxiality of the plug and the gas spring itself, resulting in the plug being skewed after welding;

[0003] To this end, we propose a double-station gas spring cylinder end-forming equipment that can not only seal the gas spring port but also increase the wall thickness of the sealing portion, so that the later sealing portion has a certain thickness after the drilling is completed, and assists in correcting the plug when inserting it for welding, thereby greatly improving the coaxiality of the welding between the plug and the gas spring end.

[0038] like Figures 1 to 9 As shown, this application provides:

[0039] A double-station gas spring cylinder closing and forming equipment comprises a frame 1, a material storage unit 2, a material guiding device 3, a cylinder clamping device 4, a first cold bending device 5 and a second cold bending device 6; the material storage unit 2 is fixedly mounted on the frame 1 and is located on one side of the material storage unit 2, and the material inlet of the material guiding device 3 is arranged opposite to the material outlet of the material storage unit 2; the cylinder clamping device 4 is fixedly mounted at the material outlet of the material guiding device 3 in a vertical state, and the cylinder clamping device 4 consists of a first cylinder clamping mechanism 4a and a second cylinder clamping mechanism 4b; the clamping ends of the first cylinder clamping mechanism 4a and the second cylinder clamping mechanism 4b are also respectively provided with a first cold bending device 5 and a second cold bending device 6 in a one-to-one correspondence.

[0040] Based on the above embodiment, when the gas spring cylinder needs to be closed in the working state, the gas spring cylinder is first transferred to the material guiding device 3 through the material storage unit 2. After the material guiding device 3 receives the gas spring cylinder, the material guiding device 3 will automatically distinguish the gas spring cylinder according to the diameter of the gas spring cylinder, and transfer it to the first cylinder clamping mechanism 4a and the second cylinder clamping mechanism 4b respectively.

[0041] Further, such as Figure 4 As shown:

[0042] The material guiding device 3 includes a first material dividing platform 3a, a second material dividing platform 3b and a linear drive 3c; the first material dividing platform 3a and the second material dividing platform 3b are respectively fixedly installed on the frame 1 in a vertical state, and the first material dividing platform 3a and the second material dividing platform 3b are connected end to end. Two linear drives 3c are provided, and the two linear drives 3c are respectively horizontally arranged on one side of the first material dividing platform 3a and the second material dividing platform 3b, and the driving ends of the two linear drives 3c are respectively arranged toward the first material dividing platform 3a and the second material dividing platform 3b.

[0043] Based on the above embodiment, the first material distribution platform 3a and the second material distribution platform 3b are both existing technologies and will not be described here in detail. In the working state, when the gas spring cylinder moves to the first material distribution platform 3a and the second material distribution platform 3b under the transmission of the storage unit 2, the first material distribution platform 3a and the second material distribution platform 3b will drive the gas spring cylinder according to the diameter of the gas spring cylinder, and move toward the first cylinder clamping mechanism 4a or the second cylinder clamping mechanism 4b under the drive of the linear drive 3c corresponding to the side of the first material distribution platform 3a and the second material distribution platform 3b, thereby completing the closing of the gas spring cylinder.

[0044] Further, such as Figures 5 to 7 As shown:

[0045] The first cold bending device 5 includes a rotating unit 5a, an adjusting unit 5b, a first horizontal adjustment group 5b1, a second horizontal adjustment group 5b2, a third horizontal adjustment group 5b3, a cold bending mechanism 5c, a correction unit 5d, a lubrication assembly 5e, a material withdrawal mechanism 5f and a sensor unit 5g; the adjusting unit 5b is fixedly mounted on the frame 1, and the adjusting unit 5b is composed of the first horizontal adjustment group 5b1, the second horizontal adjustment group 5b2 and the third horizontal adjustment group 5b3, the rotating unit 5a is rotatably arranged on the first horizontal adjustment group 5b1 in a vertical state, the top of the rotating unit 5a passes through the first horizontal adjustment group 5b1 and is arranged vertically upward, the second horizontal adjustment group 5b2 is fixedly mounted on the top of the rotating unit 5a; the third horizontal adjustment group 5b3 is slidably arranged on the third horizontal adjustment group 5b3; The mechanism 5c is slidably arranged on the third horizontal adjustment group 5b3 in a vertical state; the correction unit 5d is fixedly installed on one side of the top of the cold bending mechanism 5c in a vertical state; the lubrication assembly 5e is fixedly installed on the other side of the top of the cold bending mechanism 5c relative to the correction unit 5d, and the output end of the lubrication assembly 5e is arranged opposite to the output end of the cold bending mechanism 5c; the correction unit 5d and the lubrication assembly 5e are both arranged on the side close to the cylinder clamping device 4; the material return mechanism 5f is fixedly installed on the cold bending mechanism 5c in a horizontal state, and the material return mechanism 5f is arranged on the other side away from the cylinder clamping device 4, and the output end of the material return mechanism 5f is coaxial with the clamping end of the cylinder clamping device 4 and is arranged toward the clamping end of the cylinder clamping device 4; the sensor unit 5g is fixedly installed on the frame 1, and the sensor unit 5g is arranged around the adjustment unit 5b.

[0046] Based on the above embodiment, when it is necessary to close the end of the gas spring cylinder in the working state, the gas spring cylinder will be pushed into the cylinder clamping device 4 under the drive of the linear drive 3c, and pass through the cylinder clamping device 4. When the linear drive 3c is pushing the gas spring cylinder, the output end of the correction unit 5d fixedly installed on the cold bending mechanism 5c will drop vertically and block in front of the cylinder clamping device 4, and the end of the gas spring cylinder pushed toward the cold bending mechanism 5c by the linear drive 3c will stop moving after touching the output end of the correction unit 5d, thereby completing the limit correction work on the end closing length of the gas spring cylinder. After the gas spring cylinder stops moving, the clamping end of the cylinder clamping device 4 tightens and clamps the gas spring cylinder and drives the gas spring cylinder to rotate. The output end of the correction unit 5d returns to the initial state, and then drives the rotating unit 5a to rotate, thereby driving the entire cold bending device to rotate synchronously. The output end of the cold bending mechanism 5c is used to squeeze and close the port of the gas spring cylinder. After the closing is completed, the rotating unit 5a returns to its initial state, and finally drives the material withdrawal mechanism 5f to eject the gas spring cylinder located in the cylinder clamping device 4. The lubrication component 5e is used to intermittently spray oil toward the output end of the cold bending mechanism 5c, so as to maintain continuous lubrication of the output end of the cold bending mechanism 5c and extend the service life of the cold bending mechanism 5c. The sensor unit 5g is used to detect the rotation state of the adjustment unit 5b to avoid overtravel of the adjustment unit 5b; the structures of the second horizontal adjustment group 5b2 and the third horizontal adjustment group 5b3 are the same as those of the first horizontal adjustment group 5b1; the adjustment directions of the first horizontal adjustment group 5b1, the second horizontal adjustment group 5b2 and the third horizontal adjustment group 5b3 are arranged in a horizontal and vertical staggered manner from bottom to top, so as to be suitable for multi-directional horizontal adjustment of the X direction and the Y direction of the cold bending mechanism 5c.

[0047] Further, such as Figure 6 and Figure 8 As shown:

[0048] The rotating unit 5a includes a rotating driver 5a1, a connecting member 5a2, a driving shaft 5a3 and a rotating block 5a4; the rotating driver 5a1 is fixedly installed at the bottom of the frame 1 in a horizontal state, the driving shaft 5a3 is rotatably arranged on the first horizontal adjustment group 5b1, and the rotating block 5a4 is fixedly installed at the top of the driving shaft 5a3; the connecting member 5a2 is used for transmission connection between the driving end of the rotating driver 5a1 and the driving end of the driving shaft 5a3.

[0049] Based on the above embodiments, when it is necessary to drive the adjusting unit 5b, the first horizontal adjusting group 5b1, the second horizontal adjusting group 5b2, the cold bending mechanism 5c, the correction unit 5d, the lubrication assembly 5e, the material return mechanism 5f and the sensor unit 5g to move synchronously in the working state, it is only necessary to connect an external power supply to drive the rotary driver 5a1 to work, and drive the driving shaft 5a3 to rotate under the transmission of the connecting member 5a2, thereby completing the work of driving the adjusting unit 5b, the first horizontal adjusting group 5b1, the second horizontal adjusting group 5b2, the cold bending mechanism 5c, the correction unit 5d, the lubrication assembly 5e, the material return mechanism 5f and the sensor unit 5g to rotate synchronously.

[0050] Further, such as Figure 7 and Figure 8 As shown:

[0051] The first horizontal adjustment group 5b1 includes a fixed seat 5b11, a sliding seat 5b12, a locking bolt 5b13, an adjusting bolt 5b14 and a limit block 5b15; the fixed seat 5b11 is fixedly installed on the frame 1, the sliding seat 5b12 is slidably arranged on the fixed seat 5b11, a plurality of locking bolts 5b13 are provided, and the plurality of locking bolts 5b13 are in a mirror state and can be respectively screwed and disassembled and arranged on both sides of the sliding seat 5b12; the limit block 5b15 is fixedly installed on the end of the sliding seat 5b12, one end of the adjusting bolt 5b14 is rotatably arranged in the limit block 5b15, and the other end of the adjusting bolt 5b14 is also provided with a threaded portion, the threaded portion is inserted into the interior of the fixed seat 5b11 and is threadedly connected with the fixed seat 5b11.

[0052] Based on the above embodiment, when it is necessary to change the closing shape of the end of the gas spring cylinder in the working state, the staff can change the starting position of the cold bending mechanism 5c by screwing the adjusting bolt 5b14, thereby adjusting the closing angle and shape of the gas spring cylinder. The locking bolt 5b13 is used to lock and fix the sliding seat 5b12 of the first horizontal adjustment group after the adjustment is completed, so as to prevent the sliding seat 5b12 from moving autonomously due to vibration in the working state.

[0053] Further, such as Figure 8 As shown:

[0054] The cold bending mechanism 5c includes a mounting seat 5c1 and a rolling wheel 5c2; the mounting seat 5c1 is slidably mounted on the third horizontal adjustment group 5b3; the rolling wheel 5c2 is rotatably arranged in the mounting seat 5c1, and the rolling wheel 5c2 is arranged on one side close to the cylinder clamping device 4.

[0055] Based on the above embodiment, the rolling wheel 5c2 is composed of a cylindrical part and an annular protrusion formed in one piece; the connection between the cylindrical part and the annular protrusion is arranged with a smooth transition. When it is necessary to close the end of the gas spring cylinder, the rolling wheel 5c2 rotates under the drive of the rotating unit 5a and squeezes the end of the gas spring cylinder to close it until the end of the gas spring cylinder is squeezed and closed and stops; the present application adopts cold extrusion to close the end, which can increase the wall thickness of the hole at the closing point, increase the contact area of ​​the plug, make the welding more firm and not easy to fall off, and have high coaxiality of the welding.

[0056] Further, such as Fig. 9 As shown:

[0057] The correction unit 5d includes a first mounting frame 5d1, a first cylinder 5d2, a hinged joint 5d3 and a slider 5d4; the first mounting frame 5d1 is fixedly mounted on the mounting seat 5c1; the first cylinder 5d2 is fixedly mounted on the top of the first mounting frame 5d1 in a vertical state; the output end of the first cylinder 5d2 passes through the first mounting frame 5d1 and is arranged toward the mounting seat 5c1; the hinged joint 5d3 is fixedly mounted on the output end of the first cylinder 5d2, and the slider 5d4 is slidably arranged on the first mounting frame 5d1 in a vertical state, and the top of the slider 5d4 is hingedly connected to the hinged joint 5d3.

[0058] Based on the above embodiment, in the working state, before closing the end of the gas spring cylinder, the slider 5d4 will move downward under the drive of the first mounting bracket 5d1 and block to the front of the gas spring cylinder, thereby completing the limit adjustment of the extension length of the gas spring cylinder.

[0059] Further, such as Fig. 9 As shown:

[0060] The lubrication assembly 5e includes a second mounting frame 5e1 and an oil spray pipe 5e2; the second mounting frame 5e1 is fixedly mounted on the mounting seat 5c1, and the second mounting frame 5e1 is arranged directly above the rolling wheel 5c2; the oil spray pipe 5e2 is fixedly mounted on the second mounting frame 5e1 in a vertical state, and the oil spray nozzle of the oil spray pipe 5e2 is arranged directly facing the rolling wheel 5c2.

[0062] Further, such as Fig. 9 As shown:

[0063] The material return mechanism 5f includes a third mounting frame 5f1, a second cylinder 5f2 and a material ejecting rod 5f3; the third mounting frame 5f1 is fixedly mounted on the mounting seat 5c1; the second cylinder 5f2 is fixedly mounted on one side of the third mounting frame 5f1 in a horizontal state; the output end of the second cylinder 5f2 passes through the third mounting frame 5f1 and is arranged toward the cylinder clamping device 4; the material ejecting rod 5f3 is coaxially fixedly mounted on the output end of the second cylinder 5f2.

[0064] Based on the above embodiment, in the working state, when the gas spring cylinder clamped by the output end of the cylinder clamping device 4 is closed, the second cylinder 5f2 is driven to work, and the output shaft of the second cylinder 5f2 extends axially and moves toward the gas spring cylinder until the gas spring cylinder is completely ejected from the cylinder clamping device 4 and then stops.

[0067] Based on the above embodiment, the first photoelectric sensor 5g2 and the second photoelectric sensor 5g3 are used to respectively detect the rotation state of the adjusting unit 5b in the working state. When the adjusting unit 5b rotates and moves from the detection end of the first photoelectric sensor 5g2 to the detection end of the second photoelectric sensor 5g3, it is a closing process, and the distance from the detection end of the first photoelectric sensor 5g2 to the detection end of the second photoelectric sensor 5g3 is the closing movement stroke of the gas spring cylinder. A rubber head is also provided on the side wall of the cylinder clamping device 4 to prevent the adjusting unit 5b from rotating overtravel and directly colliding with the cylinder clamping device 4.
