Description

Technical Field

[0001] The invention relates to the technical field of flame cutting equipment, in particular to flame cutting equipment for producing and processing blanks of furniture hardware. Background Art

[0002] Furniture hardware refers to various metal parts used in the process of furniture manufacturing and assembly. These parts not only play the role of connection and fixing, but also increase the functionality and aesthetics of furniture, such as hinges, cylindrical slides, handles, locks, gas struts, etc. Flame cutting technology is one of the earliest metal cutting methods. Flame cutting technology is mainly used to cut rails and steel, and later gradually applied to various aspects of the industrial field. The flame cutting machine mainly uses a mixed gas such as oxygen and acetylene to spray high-temperature airflow on the metal surface to cut the metal into the desired shape.

[0003] In the prior art, when cutting a columnar workpiece in furniture hardware, the workpiece is generally placed directly on the surface of a processing table, and the position of the spray gun is controlled to cut different positions of the workpiece. Because some columnar workpieces are light in weight, in order to increase the stability of the columnar workpiece when cutting, the workpiece is sometimes clamped and fixed at both ends of the columnar workpiece by arc-shaped pressure plates on the upper and lower sides. However, during the cutting process, the columnar workpiece will inevitably vibrate due to the operation of the mechanical equipment, thereby causing the position of the workpiece to deviate, thereby reducing the accuracy of the cutting position. The method of fixing with an arc-shaped pressure plate is not only cumbersome during installation and disassembly, but also requires arc-shaped plates of different sizes to be prepared according to the diameter of the end face of the columnar workpiece, thereby increasing the processing and production cost, thereby reducing the processing and production efficiency. In addition, the arc-shaped plate is generally installed on the processing box by bolts. When processing workpieces of different lengths, it is necessary to repeatedly disassemble and install, thereby causing the problem of inconvenience in adjustment. For this reason, the present invention proposes a flame cutting device for producing and processing blanks of furniture hardware to solve the above problems. Summary of the invention

[0028] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0029] Example 1: Please refer to Figures 1 to 6The present invention provides a technical solution: a flame cutting device for producing and processing blanks of furniture hardware, comprising: a flame cutting machine body 1, a support box 2 is arranged at the bottom of the flame cutting machine body 1, main clamping mechanisms 3 are arranged on both sides of the support box 2, an auxiliary clamping mechanism 4 is installed on one side of the main clamping mechanism 3, the main clamping mechanism 3 comprises a support platform 5, a fixed ring 6 is fixedly connected to one side of the support platform 5, a rotating ring 7 is rotatably sleeved on the outer ring surface of the fixed ring 6, a large limit block 8 and a small limit block 9 are rotatably connected to one side of the fixed ring 6 and the rotating ring 7, a clamping rod 10 is slidably sleeved between the large limit block 8 and the small limit block 9, the auxiliary clamping mechanism 4 comprises an anti-skid pressure block 11, an arc block 12 is installed on one side of the anti-skid pressure block 11, the arc block 12 is fixedly connected to one end of a small threaded rod 13, and the small threaded rod 13 is threadedly sleeved in a limit sleeve 14.

[0030] The cylindrical workpiece is sleeved between the clamping rods 10 installed on both sides of the support box 2, and the support box 2 is used as the main support of the whole device. The flame cutting machine body 1 is slidably installed on the support box 2, and the main clamping mechanism 3 and the auxiliary clamping mechanism 4 are symmetrically arranged on both sides of the support box 2. The support table 5 is used as the supporting body of the clamping mechanism 3 and the auxiliary clamping mechanism 4. The support table 5 limits the fixed ring 6, and the fixed ring 6 limits the rotating ring 7, so that the rotating ring 7 can rotate on the fixed ring 6. Through the rotation of the rotating ring 7, the large limit block 8 and the small limit block 9 installed on the fixed ring 6 and the rotating ring 7 are coordinated to limit the sliding of the clamping rod 10, so that the two parallel clamping rods 10 can move toward or away from each other. When the two parallel clamping rods 10 move toward each other, the workpiece is clamped in the center under the tightening of the clamping rod 10, so as to preliminarily align it. The small threaded rod 13 is limited and fixed by twisting the small threaded rod 13. Under the limitation of the limit sleeve 14, the small threaded rod 13 can approach or move away from the axial direction of the fixing ring 6. Therefore, when the small threaded rod 13 approaches the axial direction of the fixing ring 6, the arc block 12 is driven to move, and the arc block 12 indirectly drives the anti-skid pressure block 11 to move until the anti-skid pressure block 11 abuts against the outer ring surface of the workpiece, thereby completing the auxiliary fixation of the workpiece. Then, through the setting of the main clamping mechanism 3 and the auxiliary clamping mechanism 4, the workpiece can be quickly clamped and fixed, avoiding the vibration of the entire equipment, causing the processing position of the workpiece to be deviated during the processing, thereby improving the processing accuracy. At the same time, by adjusting the rotation of the rotating ring 7 and the rotation depth of the small threaded rod 13, workpieces of different diameters can be fixed, thereby expanding the scope of use and improving the practicality of the entire device.

The limit rails 15 fixedly connected to both sides of the upper surface of the support box 2 are used to limit the flame cutting machine body 1, so as to facilitate its movement and further facilitate cutting of different positions of the workpiece. The support box 2 is fixedly connected to a limit plate 18 near the side wall of the support platform 5. A large threaded rod 19 is rotatably sleeved on one side of the limit plate 18, and a sliding rod 20 is fixedly sleeved on the other side of the limit plate 18. The limit plate 18 is "L"-shaped and is fixedly connected to the side wall of the support box 2. The large threaded rod 19 and the sliding rod 20 are rotatably sleeved on the other side of the limit plate 18. The adjustment block 21 is fixedly connected to the lower surface of the support platform 5, one side of the adjustment block 21 is threadedly sleeved in the large threaded rod 19, and the other side of the adjustment block 21 is slidably sleeved on the slide rod 20. A motor 22 is fixedly installed on one side of the adjustment block 21, and a splash cover 36 is provided on the outer cover of the motor 22. The splash cover 36 is fixedly connected to the adjustment block 21. A threaded hole is provided on one side of the bottom of the adjustment block 21, and the threaded hole is threadedly connected to the large threaded rod 19. A large handwheel is fixedly sleeved on one end of the large threaded rod 19, and a sliding hole is provided on the other side of the adjustment block 21. The sliding hole is slidably connected to the slide rod 20, and the motor 22 is fixedly installed on one side of the adjustment block 21. The motor 22 is electrically connected to the external terminal control device, and a splash cover 36 is provided on the outside of the motor 22 to prevent high-temperature residues from damaging the motor 22.

[0032] The receiving groove 16 provided on the upper surface of the support box 2 is convenient for collecting waste materials in the cutting process. The material slag can be introduced into the receiving groove 16 through the material guide plate 17 arranged obliquely in the receiving groove 16, so as to avoid the accumulation of material slag. The limit rails 15 fixedly installed on both sides of the upper surface of the support box 2 limit the two sides of the bottom of the flame cutting machine body 1, so as to facilitate its movement, and then cut different positions of the workpiece. The large hand wheel fixedly sleeved on one end of the large threaded rod 19 is driven to move, and the large threaded rod 19 is driven to move. 19 rotates under the limit of the limit plate 18, and the large threaded rod 19 is provided with two sections of threads with opposite rotation directions, so that the rotation of the large threaded rod 19 can drive the adjustment block 21 to slide along the slide rod 20, and then the distance between the two adjustment blocks 21 can be adjusted to adapt to workpieces of different lengths, avoiding the need to repeatedly disassemble and install the arc pressure plate, thereby causing the problem of inconvenient adjustment. The splash shield 36 provided on the outside of the motor 22 can prevent the high-temperature slag from splashing onto the motor 22, thereby damaging the motor 22.

[0033] Embodiment 3: On the basis of embodiment 2, the output end of the motor 22 is fixedly connected to one end of the worm 23 through a coupling, the two sides of the worm 23 are rotatably sleeved in the bearing seat, the worm 23 is meshed with one side of the half worm wheel 24 for transmission, and the other side of the half worm wheel 24 is fixedly connected to the outer ring surface of the rotating ring 7, the two sides of the worm 23 are limited by the bearing seat, one end of the worm 23 is fixedly connected to the output end of the motor 22, the motor 22 is electrically connected to the external terminal control device, the half worm wheel 24 is arranged between the worm 23 and the rotating ring 7, the inner ring surface of the rotating ring 7 is provided with a slide groove 25, the outer ring surface of the fixed ring 6 is fixedly connected with a ring rail 26, the slide groove 25 and the ring rail 26 are slidably connected, and one side of the large limit block 8 and the small limit block 9 is rotatably sleeved in the limit rod 27 A small nut is screwed on one end of the limit rod 27, and a large nut is screwed on one end of the clamping rod 10. Through the cooperation of the slide groove 25 and the ring rail 26, the rotating ring 7 is limited when rotating, thereby ensuring the stability of the rotation of the rotating ring 7. The limit rod 27 is fixedly installed on the fixed ring 6 and the rotating ring 7 through a small nut. The large limit block 8 and the small limit block 9 are limited by the limit rod 27, thereby facilitating the rotation of the large limit block 8 and the small limit block 9. The clamping rod 10 is arranged in a "well" shape, and a groove 28 is opened in the middle of the clamping rod 10. A soft pressure block 29 is fixedly connected in the groove 28. An adjusting hand wheel 30 is arranged on one side of the clamping rod 10. Two clamping rods 10 form a group, and a group of clamping rods 10 are arranged in parallel. One end of the clamping rod 10 is limited by a large nut.

[0034] When the position adjustment of the adjusting block 21 is completed, the two ends of the cylindrical workpiece are inserted between the clamping rods 10 on both sides of the supporting box 2, and the motor 22 is started. The worm 23 is driven by the rotation of the motor 22, and the worm 23 is meshed with the half worm gear 24, so that the half worm gear 24 rotates, and the half worm gear 24 drives the rotating ring 7 to move. The rotating ring 7 rotates under the cooperation of the slide groove 25 and the ring rail 26, so that the rotating ring 7 drives the large limit block 8 and the small limit block 9 installed thereon to move, thereby driving the clamping rod 10 to move, and then through the cooperation of the large limit block 8 and the small limit block 9 installed on the fixed ring 6, a group of parallel clamping rods 10 are moved toward each other. Or move backwards, when the clamping rod 10 moves towards each other, the workpiece is clamped, and when the clamping rod 10 moves backwards, the workpiece is released from the limit. When the clamping rod 10 contacts the workpiece, the soft pressure block 29 in the groove 28 in the middle thereof squeezes the outer wall of the workpiece, which clamps the workpiece on the one hand and avoids damage to the workpiece on the other hand. By controlling the rotation angle of the rotating ring 7, the distance between a group of parallel clamping rods 10 can be adjusted, thereby facilitating the clamping and fixing of workpieces of different diameters, avoiding the need to formulate arc plates of different sizes according to the diameter of the end face of the cylindrical workpiece, thereby increasing the processing and production cost, and thus reducing the processing and production efficiency.

[0035] Embodiment 4: On the basis of embodiment 3, the adjusting hand wheel 30 is fixedly connected to one end of the small threaded rod 13, and the other end of the small threaded rod 13 is fixedly connected to the arc block 12. Four small threaded rods 13 are provided and are arranged in a circular array on one side of the support platform 5. The limiting sleeve 14 is fixedly sleeved on the support platform 5. The small threaded rod 13 is fixedly connected between the adjusting hand wheel 30 and the arc block 12. The limiting sleeve 14 is fixedly sleeved on one side of the top of the support platform 5. The small threaded rod 13 is limited by the limiting sleeve 14. Limiting grooves 31 are provided on both sides of the arc block 12. Long pin shafts 32 are slidably connected in the limiting grooves 31. The long pin shafts 32 are rotatably sleeved on the connecting rod The cam 33 is provided with a first end and a second end of the connecting rod 33 is connected to the first end of the anti-skid pressure block 11 through a short pin 34. The connecting rod 33 is symmetrically arranged about the central plane of the arc block 12. The long pin 32 is fixedly connected to one end of the spring 35. The other end of the spring 35 is fixedly connected to the inner wall of the limiting groove 31. The limiting grooves 31 on both sides of the arc block 12 facilitate the sliding of the long pin 32 and also limit the spring 35. The long pin 32 is rotatably sleeved on one end of the connecting rod 33. The other end of the connecting rod 33 is installed on the side wall of the anti-skid pressure block 11 and is rotatably connected to the anti-skid pressure block 11 through a short pin 34. The short pin 34 is fixedly sleeved on the side wall of the anti-skid pressure block 11.

[0036] After the main clamping mechanism 3 completes clamping and fixing the workpiece, the auxiliary clamping mechanism 4 is used to further fix and limit the workpiece. By twisting the small threaded rod 13, under the limit of the limit sleeve 14, the small threaded rod 13 moves toward the axial direction close to the fixing ring 6, thereby driving the arc block 12 to move. The arc block 12 drives the anti-skid pressure block 11 to move toward the outer ring surface of the workpiece under the connection action of the connecting rod 33 until the anti-skid pressure block 11 abuts against the outer ring surface of the workpiece, and then the small threaded rod 13 is continued to be twisted to make the anti-skid pressure block 11 contact the workpiece. The surface of the workpiece generates an extrusion force. At this time, one end of the connecting rod 33 rotates on the side wall of the anti-skid pressure block 11 through the connection of the short pin shaft 34, and the long pin shaft 32 that is rotatably sleeved on the other end of the connecting rod 33 slides under the limit of the limit groove 31, so that the long pin shaft 32 squeezes the spring 35, and the spring 35 is compressed to generate a reverse elastic force, so that the anti-skid pressure block 11 can fit more closely to the surface of the workpiece, avoiding the rolling of the cylindrical workpiece during the cutting process, further improving the accuracy and stability of the cutting process, and also improving the processing quality.
