Description

Technical Field

[0001] The invention relates to the technical field of metal nail turning, in particular to a metal nail turning device. Background Art

[0002] The metal nail turning equipment with automatic material pushing is a kind of equipment that integrates automation technology and turning process. It can automatically push and fix the metal nails during the turning process, so as to improve the processing accuracy and production efficiency. Before processing, the equipment will first place the metal nail raw material in the specified position and push and fix it through the automatic material pushing device. Then the turning system starts to work and accurately turns the metal nails according to the preset program and parameters. During the processing, the control system will monitor the operating status and processing quality of the equipment in real time to ensure the stability and accuracy of the processing process. Through automatic control and precise turning system, the processing accuracy and dimensional consistency of metal nails can be ensured, and the manual intervention and waiting time can be reduced through automated production, which improves the production efficiency and output. The equipment can be widely used in the production of hardware products, fasteners, automotive parts and other industries; In the actual turning process, the hardness of metal nail raw materials with different requirements in different batches is often different. High-hardness materials have strong resistance to cutting, and greater resistance needs to be overcome during the cutting process. As the hardness of the material increases, the cutting force will also increase accordingly, which may cause the load of the machine tool and the tool to increase, affecting the cutting stability and tool life. The cutting heat generated by high-hardness materials during the cutting process is also higher. Because the cutting force is large, more energy is required for material deformation, and most of this energy is converted into heat. The increase in cutting temperature may cause thermal deformation of the workpiece, increased tool wear, and decreased cooling effect of the cutting fluid. In order to maintain the stability of the cutting process and slow down tool wear, the cutting speed needs to be appropriately reduced, which can reduce heat and wear during the cutting process. When cutting high-hardness materials, if the cutting speed is too fast, it may cause the vibration of the machine tool and the tool to increase, thereby affecting the processing accuracy and even causing certain safety hazards. For this reason, we propose a metal nail turning equipment with automatic material ejection. Summary of the invention

Through the cooperation between the inclined surface of the wedge-shaped seat 26 and the end of the clamping block 28, the clamping block 28 moves along the slide groove 31 while moving out of the sleeve 13, and releases the clamping of the metal nail raw material. The elastic force of the second spring 25 pushes the slide 24 out of the sleeve 13 and ejects the metal nail raw material, thereby realizing automatic ejection.

When the slide 24 moves to the bottom of the output end of the first cylinder 14, the first cylinder 14 will retract, driving the fixed block 22 and the clamping block 28 to move into the sleeve 13.

The limit column 21 in the electromagnetic block 15 is limited by the slot 23 on the fixed block 22, and the retraction amplitude of the fixed block 22 and the block 28 is adjusted to make the metal nail raw material It can be firmly clamped, and the fixed block 22 and the clamping block 28 are not easy to slide. When the fixed block 22 needs to slide, the electromagnetic induction driving principle is used to make the limit column 21 slide into the electromagnetic slot 19 under the electromagnetic force, and the first spring 20 is compressed. When the fixed block 22 moves to a suitable position, the electromagnetic force is released, and the limit column 21 is ejected by the elastic force of the first spring 20 and inserted into the clamping slot 23. The positions of the fixed block 22 and the clamping block 28 are fixed. When the motor 12 drives the sleeve 13 to move, the electromagnetic block 15 will rotate synchronously with the sleeve 13, and through the cooperation of the ball 17 and the annular groove 18, the friction between the electromagnetic block 15 and the inner wall of the limit ring 16 during the rotation process is reduced. A cooling device 2 is fixedly installed on the lathe 1 (the cooling device 2 is an existing known structure,Therefore, the present invention will not be described in detail. A plurality of nozzles 3 are fixedly mounted on the cooling device 2, a bracket 4 for fixing the nozzles 3 is fixedly mounted on the lathe 1, a collection frame 5 is slidably mounted on the cooling device 2, and a plurality of filter holes 6 for filtering the coolant are arranged at the bottom of the collection frame 5. During the turning process, the nozzle 3 sprays coolant for cooling, and the metal nails ejected after the turning is completed fall into the collection frame 5 below, and the excess coolant returns to the cooling device 2 through the filter holes 6 at the bottom of the collection frame 5 for recycling.

[0021] A power seat 43 is fixedly installed on the lathe 1, and a tool holder 44 is slidably installed on the power seat 43. A plurality of tool grooves 49 are provided on the tool holder 44, and different turning tools 47 are provided in the tool grooves 49. Pads 48 for anti-slip are fixedly installed on both sides of each turning tool 47. A fixing plate 45 is provided on both sides of each turning tool 47. Each fixing plate 45 is fixedly installed on the tool holder 44, and a plurality of screws 46 for fixing the turning tool 47 are threadedly installed on each fixing plate 45. After the turning tool 47 and the pad 48 are placed in the corresponding tool groove 49, the screws 46 are tightened, and the turning tool 47 is fixed to the tool holder 44 by the screws 46 on both sides. A stepped groove 32 is provided in the fixed seat 7. Each layer in the stepped groove 32 is arranged in a gully shape, and the depth of each layer gradually increases from top to bottom. A vibration detection ball 34 is arranged in the stepped groove 32, and a rotating rod 35 is rotatably installed in the fixed seat 7. A connecting rope 36 is wound around the rotating rod 35. One end of the connecting rope 36 is fixedly connected to the end of the rotating rod 35, and the other end is fixedly connected to the vibration detection ball 34. A knob 42 for resetting the rotating rod 35 is fixedly installed at one end.

One end of the adjusting button 38 is rotatably connected to the rotating rod 35, and the other end is fixedly connected to the inner wall of the fixed seat 7 with a third spring 39. A protrusion 40 is fixedly installed at one end of the rotating rod 35, and a threaded groove 4 for limiting the protrusion 40 is arranged in the fixed seat 7. 1. The rotating rod 35 is provided with a spiral groove 37 for limiting the connecting rope 36. The pitch of the spiral groove 37 is the same as the pitch of the thread groove 41. According to the hardness of the metal nail material, the fixed seat 7 will vibrate to different degrees during the turning process. According to the amplitude of the vibration, the vibration detection ball 34 will move irregularly in the stepped groove 32. When the vibration reaches a certain amplitude, the movement amplitude of the vibration detection ball 34 will cause it to break away from the limit of the top platform of the stepped groove 32, and fall into different platforms in the stepped groove 32 according to the vibration amplitude of the fixed seat 7. When the vibration detection ball 34 moves downward to the stepped groove 32, it will drive one end of the connecting rope 36 to move and rotate the rotating rod 35. Through the limit of the protrusion 40 by the thread groove 41, the rotating rod 35 drives the knob 42 to rotate. While moving outward from the fixed seat 7, the adjusting button 38 is driven to slide in the fixed seat 7, the third spring 39 is stretched, and the elasticity of the third spring 39 keeps the connecting rope 36 in a straight state, so as to prevent the vibration detection ball 34 from bringing out too much connecting rope 36 and being unable to be recovered during the movement. According to the sliding distance of the adjusting button 38, the operating speeds of the power seat 43 and the motor 12 are successively slowed down, so that the turning speed is reduced, the wear of the turning tool 47 and the heat generated during the turning process are reduced, and at the same time, the cooling device 2 is controlled to make the nozzle 3 spray more coolant for cooling. When a batch of metal nails is turned and the next batch is processed, the knob 42 is turned into the fixed seat 7. Since the pitch of the spiral groove 37 is the same as the pitch of the thread groove 41, when the knob 42 drives the rotating rod 35 to reverse,The connecting rope 36 is also recovered and re-wound along the spiral groove 37. At the same time, the vibration detection ball 34 is pulled back to the uppermost end of the stepped groove 32, and the adjusting button 38 and the third spring 39 are reset. The bottom of each platform in the stepped groove 32 is fixedly installed with a sensing plate 33, and the tool holder 44 is fixedly installed with a second cylinder 50 whose telescopic range is controlled by the sensing plate 33. Reinforcement plates 54 are provided on both sides of each turning tool 47, and a telescopic column 53 is fixedly installed at one end of each reinforcement plate 54. A through groove 56 is opened on the tool holder 44, and the telescopic column 53 passes through the through groove 56. A plurality of limiting holes 55 for limiting the telescopic column 53 are provided in the tool holder 44, and the limiting holes 55 correspond to the telescopic columns 53 one by one. A wedge block 51 is fixedly installed at one end of each telescopic column 53, and a plurality of step blocks 51 cooperating with the wedge blocks 51 are provided in the tool holder 44. The step plate 52, each step plate 52 is fixedly installed at the output end of the second cylinder 50. After the vibration detection ball 34 falls into different platforms in the step groove 32, the corresponding induction plate 33 will be sensed and the second cylinder 50 will be extended to a corresponding distance. Through the cooperation of different inclined surfaces of the step plate 52 and the inclined surfaces of the wedge block 51, and the limiting hole 55 on the telescopic column 53, the wedge block 51 is pushed toward the reinforcement plate 54 and the telescopic column 53 is compressed. According to the different movement amplitudes of the step plate 52, the telescopic column 53 will be compressed to different degrees. The reinforcement plate 54 reinforces the turning tool 47 with different strengths. The higher the hardness of the metal nail material, the greater the vibration generated, and the greater the reinforcement force applied by the reinforcement plate 54, which can effectively improve the stability of turning and avoid continuously applying excessive reinforcement force to the turning tool 47, resulting in damage to the turning tool 47.

[0022] Specifically, it is first necessary to put the turning tool 47 and the pad 48 into the corresponding tool groove 49, and then tighten the screw 46. The turning tool 47 is clamped on the tool holder 44 by the screws 46 on both sides. At the same time, when the material is not loaded, the position of the limit ring 16 is adjusted according to the size of the metal nail raw material. The limit ring 16 limits the electromagnetic block 15 and synchronously adjusts the position of the electromagnetic block 15 on the sleeve 13. When loading, the metal nail raw material in the storage tray 8 will roll into the receiving card 9 due to gravity, and only one metal nail raw material can be stored in the receiving card 9 at a time. Then the receiving card 9 will descend and align with the center position of the sleeve 13, and the baffle 11 will descend with the receiving card 9 to prevent the metal nail raw material in the storage tray 8 from rolling down, and the pushing rod 10 will then The metal nail raw material in the receiving card 9 is ejected and pushed into the sleeve 13. The metal nail raw material will first contact the slide 24 and make the slide 24 move into the sleeve 13. The second spring 25 will also be compressed. When the slide 24 moves to the bottom of the output end of the first cylinder 14, the first cylinder 14 will retract, driving the fixed block 22 and the clamping block 28 to move into the sleeve 13. At the same time, the guide groove 29 limits the guide bar 27, so that the clamping block 28 moves along the slide groove 31 and clamps the metal nail raw material. The metal nail raw material is limited by the clamping block 28, and the elastic force of the second spring 25 cannot push the slide 24 and the metal nail raw material out. At the same time, the fixing block 22 and the clamping block 2 are adjusted by the clamping groove 23 on the fixing block 22 to limit the limit column 21 in the electromagnetic block 15. 8 retraction amplitude, so that the metal nail material can be firmly clamped, and the fixed block 22 and the clamping block 28 are not easy to slide. When the fixed block 22 needs to slide, the electromagnetic induction driving principle is used to make the limit column 21 slide into the electromagnetic slot 19 by the electromagnetic force, and the first spring 20 is compressed. When the fixed block 22 moves to a suitable position, the electromagnetic force is released, and the limit column 21 is ejected by the elastic force of the first spring 20 and inserted into the clamping slot 23. The positions of the fixed block 22 and the clamping block 28 are fixed. When the motor 12 drives the sleeve 13 to move, the electromagnetic block 15 will rotate synchronously with the sleeve 13. When turning, the motor 12 is started, driving the output end sleeve 13 to rotate, and driving the first cylinder 14 and the fixed block 22 to rotate synchronously. Through the fixed block 22 to limit the clamping block 28, The clamping block 28 is made to clamp the metal nail raw material and rotate and turn it. During the turning process, the fixed seat 7 will vibrate to different degrees. According to the amplitude of the vibration, the vibration detection ball 34 will move irregularly in the step groove 32. When the vibration reaches a certain amplitude, the movement amplitude of the vibration detection ball 34 will make it break away from the limit of the top platform of the step groove 32, and fall into different platforms in the step groove 32 according to the vibration amplitude of the fixed seat 7. When the vibration detection ball 34 moves downward to the step groove 32, it will drive one end of the connecting rope 36 to move and make the rotating rod 35 rotate. Through the limit of the protrusion 40 by the threaded groove 41, the rotating rod 35 drives the knob 42 to rotate and move out of the fixed seat 7, and drives the adjusting button 38 to slide in the fixed seat 7, and the third spring 39 is stretched.The elasticity of the third spring 39 keeps the connecting rope 36 in a straight state to prevent the vibration ball 34 from carrying out too much connecting rope 36 during movement and being unable to be recovered. According to the sliding distance of the adjusting button 38, the operating speeds of the power seat 43 and the motor 12 are successively slowed down to reduce the turning speed. At the same time, the cooling device 2 is controlled to make the nozzle 3 spray more coolant for cooling. After the vibration ball 34 falls into different platforms in the stepped groove 32, the corresponding induction plate 33 will be sensed, and the second cylinder 50 will be extended by a corresponding distance. Through the cooperation of different inclined surfaces of the stepped plate 52 and the inclined surfaces of the wedge block 51, and the limiting hole 55 on the telescopic column 53, the wedge block 51 is pushed toward the reinforcement plate 54 and the telescopic column 53 is compressed. According to the different movement amplitudes of the stepped plate 52, the telescopic column 53 will be compressed to different degrees. The reinforcement plate 54 reinforces the turning tool 47 with different strengths. The higher the hardness of the metal nail material, the more vibration is generated. The greater the movement, the greater the reinforcing force applied by the reinforcing plate 54. When the turning is completed, the motor 12 stops working, and then the first cylinder 14 starts to push the fixed block 22 and the clamping block 28 outward. Through the cooperation between the inclined surface of the wedge-shaped seat 26 and the end of the clamping block 28, the clamping block 28 moves along the slide groove 31 when moving out of the sleeve 13, and releases the clamping of the metal nail raw material. The elastic force of the second spring 25 pushes the slide 24 out of the sleeve 13 and pushes the metal nail raw material out. The pushed-out metal nail falls into the collection frame 5 below. When the next batch of processing is carried out, the knob 42 is rotated into the fixed seat 7. Since the pitch of the spiral groove 37 is the same as the pitch of the thread groove 41, when the knob 42 drives the rotating rod 35 to reverse, the connecting rope 36 is also recovered and re-wound along the spiral groove 37. At the same time, the vibration detection ball 34 is pulled back to the uppermost end of the stepped groove 32, and the adjusting button 38 and the third spring 39 are reset.
