Description

Technical Field

[0001] This utility model relates to the field of lamp tube processing technology, and more specifically, to a UV lamp tube flame cutting device. Background Technology

[0002] UV is short for Ultraviolet. A UV lamp is short for an ultraviolet lamp. First-generation LED lamps used transparent glass, producing a glaring light, but still meeting traditional lighting needs. Second-generation lamps used glass tubes coated with powder or PC diffusion film, housing LED beads to reduce glare. The production of UV lamps requires a long quartz glass tube to be divided into several smaller sections.

[0003] Current UV lamp cutting methods include mechanical cutting and simple flame cutting. During mechanical cutting, using diamond cutting wheels or abrasive wheels, mechanical stress causes chipping and hidden cracks in the cross-section. During flame cutting, the uneven temperature distribution caused by unilateral flame heating results in a slanted cross-section, requiring manual rotation of the lamp for multiple heating cycles, which is inefficient and can easily cause tilting and deformation at the fracture point. This necessitates further processing of the fracture site, which is inconvenient and leads to a high scrap rate. In addition, existing cutting equipment has poor adaptability. When cutting glass tubes, it is not convenient to quickly adjust the fixture according to the diameter of the glass tube, making it inconvenient to quickly cut UV lamps of different diameters and lengths.

[0006] A translation unit is installed at the bottom of the processing base, and the output end of the translation unit is fixed to the assembly base for driving the assembly base to move horizontally in a straight line;

[0007] A support unit, which is mounted on the processing base, is used to support the lamp tube to be cut;

[0008] The cutting section is fixed on the processing base and corresponds to the bearing section, and is used to make slight scratches around the surface of the lamp tube to be processed;

[0010] Furthermore, the fusion section includes an assembly ring fixed to the other end of the upper surface of the processing base; a plurality of assembly slots arranged in a ring array on the assembly ring; a plurality of flame cutting heads respectively disposed in the plurality of assembly slots; a plurality of positioning bolts threaded to the side of the assembly ring and corresponding to the plurality of assembly slots; and a plurality of abutment blocks rotatably connected to the tail ends of the plurality of positioning bolts and respectively abutting against the outer walls of the plurality of flame cutting heads.

[0011] The assembly ring and the three-jaw chuck are on the same axis.

[0012] Furthermore, the bearing portion includes a bearing platform disposed above the processing seat; a plurality of support blocks fixed at equal intervals on the upper surface of the bearing platform; a plurality of V-shaped receiving grooves separately opened on the upper surface of the plurality of support blocks; a plurality of support rollers symmetrically rotatably installed in the plurality of support blocks; and a plurality of rubber sleeves fixedly sleeved on the outside of the plurality of support rollers.

[0013] Furthermore, the bearing portion also includes a support frame fixed to the lower surface of the bearing platform and slidably connected to the machining seat; an adjusting bolt rotatably mounted on the lower surface of the machining seat and threadedly connected to the support frame; several guide grooves formed at the four corners of the bearing platform; and several guide rods respectively fitted and slidably inserted into the several guide grooves and fixed to the upper surface of the machining seat.

[0014] Furthermore, the cutting section includes a cylinder disposed directly above the bearing section; a cutting seat fixed to the telescopic end of the cylinder; a cutting head slidably mounted on the front end of the cutting seat; and a return spring with one end fixedly connected to the top of the cutting head and the other end fixed to the cutting seat.

[0015] Furthermore, the cutting section also includes a bracket fixed to the upper surface of the processing seat; a translation seat fixedly connected to the upper end of the bracket; two limiting rods symmetrically fixed in the translation seat; a movable stage slidably connected to the translation seat through the two limiting rods; and an electric push rod fixed on the translation seat.

[0016] The telescopic end of the electric push rod is fixedly connected to one side of the moving platform;

[0017] The cylinder is fixed to the front side of the moving platform.

[0018] Furthermore, the translation unit includes a translation frame fixed to the bottom of the machining base; a push block slidably installed in the translation frame; a second motor installed on the translation frame; a drive screw rotatably installed in the translation frame and threadedly connected to the push block; a connecting frame with one end fixedly connected to the push block and the other end fixedly connected to the lower surface of the assembly base; and a movable slot formed on the machining base for the connecting frame to move.

[0019] The output end of the second motor is fixedly connected to one end of the drive screw.

[0020] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0021] 1. This UV lamp flame cutting device uses a three-jaw chuck with several buffer sleeves to flexibly clamp the glass tube. Under the control of the translation unit and the drive of the first motor, the fixed glass tube is controlled to move horizontally and rotate, gradually approaching the cutting part and the melting part. The cutting part forms a stable annular fine cutting at the rotating glass tube. Then, at the melting part, multiple flame cutting heads uniformly heat the annular cutting part of the glass tube. Through local rapid heating, a temperature gradient is generated, causing the cutting part of the glass tube to form a directional fracture due to the difference in thermal expansion under the constraint of the cutting part. This ensures the flatness of the cut surface and guarantees the geometry of the cut, ensuring the cutting quality of the UV lamp tube, facilitating subsequent processing of the UV lamp tube, and reducing the generation of cutting dust, thus maintaining a clean working environment.

[0022] 2. The UV lamp flame cutting device has a vertically adjustable support section for stable support of glass tubes of different diameters. Several flame cutting heads in the fusing section can move radially along several assembly grooves, moving closer to or further away from the glass tube to be processed. This ensures that the flame focus of the flame cutting heads always falls on the glass tube's cutting line, facilitating effective heating and cutting of glass tubes of different diameters. Simultaneously, the cutting head in the cutting section can be controlled to move horizontally, allowing for cutting at different positions on the glass tube. This facilitates the production of UV lamps of different lengths, ensuring the device's practicality and enabling rapid cutting of UV lamps of different diameters and lengths.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0034] like Figure 1-7 As shown, a UV lamp tube flame cutting device includes: a processing base 1, an assembly base 2 is provided at one end of the upper surface of the processing base 1, a first motor 3 is installed on the assembly base 2, the output end of the first motor 3 passes through the assembly base 2 and is fixed with a three-jaw chuck 4, and a buffer sleeve 5 is fixedly connected to each of the three jaws of the three-jaw chuck 4.

[0035] Translation unit 6 is installed at the bottom of the processing base 1, and the output end of the translation unit 6 is fixed to the assembly base 2, for driving the assembly base 2 to move horizontally in a straight line;

[0036] The support part 7 is mounted on the processing base 1 and is used to support the lamp tube to be cut;

[0037] The cutting part 8 is fixed on the processing base 1 and corresponds to the bearing part 7, and is used to cut slight scratches around the surface of the lamp tube to be processed.

[0038] The fusing part 9 is disposed on the upper surface of the processing base 1 and is on the same axis as the three-jaw chuck 4, and is used to uniformly heat the cutting scratches of the lamp tube to be processed.

[0039] In use, the glass tube to be processed is placed on the support part 7, and one end of the glass tube is clamped and fixed by the three-jaw chuck 4. Several buffer sleeves 5 provide flexible clamping to prevent the brittle glass from being crushed. The cooperation of several V-grooves, support rollers 18 and rubber sleeves 19 in the support part 7 keeps the glass tube stable and ensures that the glass tube is in a straight state. During the processing of the glass tube, the first motor 3 drives the three-jaw chuck 4 to rotate the glass tube, and the several support rollers 18 will rotate with the glass tube, thereby dynamically stabilizing the glass tube. A fixed support is provided to ensure stability during cutting. Then, under the control of the translation unit 6, the three-jaw chuck 4 on the assembly base 2 fixes the glass tube and moves horizontally above the processing base 1, approaching the fusing part 9. Simultaneously, the cutting part 8 operates, controlling the cutting head 26 to move horizontally along the glass tube axis. Based on the required processing length of the UV lamp tube, the cutting position of the glass tube is determined. The cylinder 24 drives the cutting head 26 to press down, and the return spring 27 maintains constant pressure, forming a slightly deep annular cut on the surface of the rotating glass tube. Then… The glass tube's cut edge moves into the fusing section 9. Several flame cutting heads 12 simultaneously spray flames within the assembly ring 10, annularly heating the pre-cut area of ​​the cut section 8. This localized rapid heating generates a temperature gradient, causing the glass tube to fracture directionally at the cut edge due to thermal expansion differences. The pre-cut guides the fracture path, ensuring a smooth fracture surface and maintaining the geometric shape of the cut, thus guaranteeing the cutting quality of the UV lamp tube. This eliminates the need for subsequent grinding, effectively improving the yield rate of the UV lamp tube. Furthermore, due to the... Several flame cutting heads 12 can move radially along several mounting grooves 11, approaching or moving away from the glass tube to be processed, ensuring that the flame focus of several flame cutting heads 12 always falls on the glass tube cutting line, facilitating effective heating and cutting of glass tubes of different diameters, and facilitating the replacement of flame cutting heads 12. In the bearing part 7, several support blocks 16 can be vertically adjusted to adapt to the glass tube diameter, so as to provide stable support for glass tubes of different diameters, facilitating the cutting and processing of glass tubes of different diameters, and ensuring the practicality of the device.

[0040] Optionally, the fusion section 9 includes an assembly ring 10 fixed to the other end of the upper surface of the processing base 1; a plurality of assembly grooves 11 arranged in a ring array on the assembly ring 10; a plurality of flame cutting heads 12 respectively disposed in the plurality of assembly grooves 11; a plurality of positioning bolts 13 threadedly connected to the side of the assembly ring 10 and corresponding to the plurality of assembly grooves 11; and a plurality of abutment blocks 14 respectively rotatably connected to the tail ends of the plurality of positioning bolts 13 and respectively abutting against the outer wall of the plurality of flame cutting heads 12.

[0041] The assembly ring 10 and the three-jaw chuck 4 are on the same axis;

[0042] Multiple flame cutting heads 12 are evenly distributed in a ring along the assembly ring 10. During use, the flame cutting heads 12 simultaneously emit high-temperature flames to annularly heat the pre-cut area at the cutting point 8, forming a closed thermal field. This localized rapid heating generates a temperature gradient, causing the glass to fracture directionally at the cutting point due to thermal expansion differences, thus completing the glass tube cutting. The flame melting and fracture process ensures cutting quality, effectively reduces the roughness of the cut surface, and avoids the generation of glass dust. The flame jet direction of the multiple flame cutting heads 12 forms an angle of 15 to 30° with the axis of the glass tube, forming a spiral... The heating path is rotated to ensure the heating effect on the glass tube. Several flame cutting heads 12 are inserted into several assembly slots 11. By rotating the positioning bolts 13, the abutment blocks 14 are driven to abut against the flame cutting heads 12 to fix them. When needed, the positioning bolts 13 can be rotated to release the restriction on the flame cutting heads 12, allowing the flame cutting heads 12 to move radially along the assembly slots 11, closer to or away from the glass tube. This ensures that the flame focus of the several flame cutting heads 12 always falls on the cutting line of the glass tube, thus facilitating the effective heating and cutting of glass tubes of different diameters, and making it highly practical.

[0043] Optionally, the bearing part 7 includes a bearing platform 15 disposed above the processing base 1; a plurality of support blocks 16 fixed at equal intervals on the upper surface of the bearing platform 15; a plurality of V-shaped receiving grooves 17 separately opened on the upper surface of the plurality of support blocks 16; a plurality of support rollers 18 respectively symmetrically rotatably installed in the plurality of support blocks 16; and a plurality of rubber sleeves 19 fixedly sleeved on the outside of the plurality of support rollers 18.

[0044] In use, the glass tube is placed in the V-shaped receiving groove 17 within several support blocks 16. At this time, the support rollers 18 on the support blocks 16 are in contact with the outer wall of the glass tube to support it. The support blocks 16 are arranged at equal intervals to effectively prevent the glass tube from bending and deforming at the processing position. During the rotational cutting process of the glass tube, the support rollers 18 will roll along with the lamp tube to compensate for the radial force. The rubber sleeves 19 can prevent scratches from rubbing the surface of the glass tube and absorb the vibration during the processing of the glass tube, improve the cutting stability of the glass tube, reduce the fluctuation of the cut depth of the glass tube, and ensure the cutting accuracy.

[0045] Optionally, the bearing part 7 further includes a support frame 20 fixed to the lower surface of the bearing platform 15 and slidably connected to the processing seat 1; an adjusting bolt 21 rotatably mounted on the lower surface of the processing seat 1 and threadedly connected to the support frame 20; a plurality of guide grooves 22 formed at the four corners of the bearing platform 15; and a plurality of guide rods 23 respectively fitted and slidably inserted into the plurality of guide grooves 22 and fixed to the upper surface of the processing seat 1. By rotating the adjusting bolts 21, the support frame 20 is controlled to drive the bearing platform 15 to move vertically, thereby adjusting the height of the plurality of support blocks 16 on the bearing platform 15 to accurately match the glass tubes of different diameters and effectively support glass tubes of different diameters. When the bearing platform 15 moves vertically, the guide grooves 22 at the four corners cooperate with the guide rods 23 to ensure the stability of the vertical movement of the bearing platform 15 and avoid skewing during adjustment.

[0046] Optionally, the nicking section 8 includes a cylinder 24 disposed directly above the bearing section 7; a cutting seat 25 fixed to the telescopic end of the cylinder 24; a cutting head 26 slidably mounted on the front end of the cutting seat 25; and a return spring 27 with one end fixedly connected to the top of the cutting head 26 and the other end fixed to the cutting seat 25. Under the push of the cylinder 24, the cutting seat 25 moves downward, pushing the cutting head 26 to contact the surface of the glass tube. The return spring 27 is compressed after the cutting head 26 contacts the glass tube, dynamically maintaining the cutting pressure within the required range. Thus, when the glass tube is rotated under control, the cutting head 26 performs a ring-shaped cut on the glass tube, forming a ring-shaped pre-cut on the surface of the glass tube. The nicking depth is controlled by the stroke of the cylinder 24 and is about one-tenth of the tube wall thickness, facilitating the subsequent processing of the fused section.

[0047] Optionally, the cutting section 8 further includes a bracket 28 fixed to the upper surface of the processing base 1; a translation base 29 fixedly connected to the upper end of the bracket 28; two limiting rods 30 symmetrically fixed in the translation base 29; a moving stage 31 slidably connected to the translation base 29 through the two limiting rods 30; and an electric push rod 32 fixed on the translation base 29.

[0048] The telescopic end of the electric push rod 32 is fixedly connected to one side of the moving platform 31;

[0049] The cylinder 24 is fixed to the front side of the moving platform 31;

[0050] In use, the electric push rod 32 can drive the moving table 31 to move linearly along the two limit rods 30. The translation seat 29 and the bracket 28 form a stable support frame to ensure the straightness of the moving table 31's movement trajectory. This allows the cylinder 24 to drive the cutting head 26 to move horizontally along the axial direction of the lamp tube to be processed, thus facilitating the adjustment of the cutting position of the cutting head 26. This allows for the cutting of lamp tubes of different lengths, ensuring the practicality of the device.

[0051] Optionally, the translation unit 6 includes a translation frame 33 fixed to the bottom of the processing base 1; a push block 34 slidably installed in the translation frame 33; a second motor 35 installed on the translation frame 33; a drive screw 36 rotatably installed in the translation frame 33 and threadedly connected to the push block 34; a connecting frame 37 with one end fixedly connected to the push block 34 and the other end fixedly connected to the lower surface of the assembly base 2; and a movable groove 38 formed on the processing base 1 for the connecting frame 37 to move.

[0052] The output end of the second motor 35 is fixedly connected to one end of the drive screw 36. In use, the second motor 35 controls the drive screw 36 to rotate, thereby causing the push block 34 to move horizontally in the translation frame 33. This controls the connecting frame 37 to move horizontally on the upper surface of the processing seat 1 under the restriction of the movable groove 38, so as to push the glass tube fixed on the assembly seat 2 to approach the melting part 9 accurately and stably for melting and cutting operation.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
