Description

Technical Field

[0001] The invention relates to the technical field of heat transfer element processing, in particular to a heat transfer element shearing-then-rolling feeding device. Background Art

[0002] In the modern industrial field, heat transfer elements are widely used in many equipment such as air conditioners, refrigerators, automobile radiators, industrial heat exchangers, etc. Shearing followed by rolling is the key processing technology of heat transfer elements. The sheared heat transfer elements are sent to rolling through a feeding device. As the core link, its performance plays a decisive role in the production quality and efficiency of heat transfer elements.

[0003] Patent publication number "CN106346072B" discloses a feeding device of a shearing machine. Through an adjustment device, the clamping mechanism is swung to a certain position, so that the bar material deviates from the fixed blade of the shearing machine. When the feeding mechanism is feeding, the bar material will not be scratched with the fixed blade. When the shearing machine is cutting, the clamping mechanism can swing relative to the feeding mechanism. Although the bar material can be pressed against the fixed blade, stable cutting is ensured, and the processing quality of the bar material is guaranteed.

[0004] However, in actual use, when the shearing tool is used for a long time, it will inevitably cause problems such as edge wear and blunting. This will not only cause the cut of the bar to become rough and uneven, but also produce defects such as burrs and deformation, affecting the processing accuracy and surface quality of the bar.

[0005] Based on this, the present application proposes a heat transfer element shearing-then-rolling feeding device. Summary of the invention

[0023] The present invention has the following beneficial effects:

[0024] Through the cutting and changing tool assembly, when the motor drives the worm to rotate, the worm wheel can drive the two-way reciprocating screw to rotate, so that the first slider drives the first gear and the cutting rod to slide, so that the two cutting knives approach each other and then cut the heat transfer element. Since the first gear is a one-way bearing, when they approach each other, the first rack will compress the spring downward, and the first gear will not rotate. When the two cutting knives move away from each other, the first gear will drive the cutting rod to rotate under the action of the first rack, so that the cutting knife under the cutting rod flips up and prepares for the next cutting. In this way, by changing the knife after cutting, it can effectively avoid continuous operation of the tool and shorten its service life.

[0025] Through the grinding assembly, when the cutting knife flips to the bottom after cutting and slides to both sides at the same time, the first reciprocating screw rotates under the drive of the worm, so that the second slider can drive the grinding block to slide back and forth at high speed, so that the cutting knife that has just completed the cutting work can be polished, which is convenient for the next round of use. This can save time for manual maintenance of the tool, and can keep the cutting knife in good working condition at all times, providing a reliable guarantee for the cutting quality.

[0026] Through the secondary processing assembly, when the heat transfer element after cutting falls onto the sieve plate, the heat transfer element that is not fully sheared will slide along the sieve plate into the delivery box. Under the rotation of the second reciprocating screw, the delivery box slides forward. When the sensor detects that the delivery box has left, the solenoid valve is controlled to close the opening of the processing box to prevent the subsequent heat transfer elements that are not fully sheared from sliding out. Subsequently, under the action of the second rack, the second gear drives the delivery box to rotate, so that the slide plate slides out under the action of gravity. At the same time, the heat transfer elements that are not fully sheared slide into the hopper through the slide plate for re-shearing. In this way, the heat transfer elements can be fully sheared, effectively improving the processing quality of the heat transfer elements.

[0027] By evenly conveying the unloading components, when the heat transfer element after shearing passes through the screen plate and falls onto the conveyor belt, the conveyor belt can drive the cut heat transfer element to the rolling place under the rotation of the shaft, and at the same time, the roller drives the baffle to rotate, so that during the rotation of the baffle, the element will be pushed back due to the blocking effect of the baffle, temporarily preventing it from moving forward; and when the baffle continues to rotate and leaves the gap of the conveyor belt, the continuous operation of the conveyor belt drives the element to be transported forward for a distance, so that the material can fall evenly from the conveyor belt to the rolling place below, avoiding excessive concentration of elements, which may cause excessive local rolling force, resulting in excessive deformation of the element or cracks.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Embodiment 1:

[0047] Reference Figure 1 and Figure 4 - Fig. 9 , a heat transfer element shearing-before-rolling feeding device, comprising a base 1, a cutting tool changing assembly, a grinding assembly, a secondary processing assembly, a uniform conveying and unloading assembly, and a transmission assembly;

[0048] The base 1 is fixedly connected with a processing box 2, and the annular groove 7 is connected with a hopper 6, through which the heat transfer element is put into the hopper 6. The processing box 2 is connected with an annular groove 7 for shearing the heat transfer element and grinding the tool. The inner wall of the annular groove 7 is fixedly connected with a first slide bar 37, and the first slide bar 37 provides a stable guide for the sliding of other components. The inner wall of the annular groove 7 is rotatably connected with a bidirectional reciprocating screw rod 11, and the bidirectional reciprocating screw rod 11 can realize bidirectional reciprocating motion, thereby driving the components matched therewith to approach or move away from each other. The inner walls on both sides of the annular groove 7 are respectively fixedly connected with slide rails 32, and the slide rails 32 further limit and guide the sliding direction of the components.

[0049] The cutting tool changer assembly is used to cut the heat transfer element;

[0050] The grinding component is used for grinding cutting tools;

[0051] The secondary processing component is used to re-shear the heat transfer element that is not sufficiently sheared;

[0052] The uniform conveying and blanking component is used to uniformly convey the heat transfer element for blanking and rolling.

[0053] The cutting tool changing assembly consists of four first sliders 39, four first gears 40, two cutting rods 30 and four cutting knives 20. The four first sliders 39 are slidably connected to the two-way reciprocating screw rod 11 and the first slide rod 37 in pairs, and the four first sliders 39 are slidably connected in pairs in two sets of slide rails 32, so that the first sliders 39 can slide smoothly. The four first gears 40 are rotatably connected to the four first sliders 39, respectively. The four first gears 40 are one-way bearings and can only rotate in one direction. The two cutting rods 30 are fixedly connected between the two first gears 40, respectively. The two cutting knives 20 are fixedly connected to the two cutting rods 30, respectively. When the two-way reciprocating screw rod 11 rotates, the first slider 39 can drive the first gear 40 and the cutting rod 30 to slide reciprocatingly, so that the cutting knives on both sides are close to or away from each other.

[0054] The two ends of the bidirectional reciprocating screw rod 11 are respectively fixedly connected with worm wheels 34, and one end of the two first reciprocating screw rods 36 is respectively fixedly connected with worm gears 33, and the two worm gears 33 are respectively meshed with the two worm gears 34. When the worm gears 33 rotate, the worm gears 34 can drive the bidirectional reciprocating screw rod 11 to rotate. Two rack boxes 38 are respectively fixedly connected to the two sides of the ring groove 7, and a plurality of springs 41 are respectively fixedly connected to the four rack boxes 38. The four rack boxes 38 are respectively slidably connected with first racks 42, and the saw teeth of the first rack 42 have an inclined surface on one side and a straight surface on the other side. One end of the plurality of springs 41 is fixedly connected to the first rack 42, and the four first racks 42 are respectively meshed with the four first gears 40. In this way, when the two first gears 40 slide close to each other, the first gears 40 can be rotated. The teeth of a gear 40 are in contact with the inclined serrations of the first rack 42. Since the first gear 40 is a one-way bearing and cannot rotate under the action of the first rack 42, the design of the inclined surface enables the first gear 40 to pass over the serrations of the first rack 42, and at the same time pushes the first rack 42 downward to compress the spring 41. When the first gear 40 leaves the first rack 42, the first rack 42 rebounds under the action of the spring 41. When the two first gears 40 slide away from each other, the teeth of the first gear 40 are in contact with the straight-face serrations of the first rack 42. Due to the blocking effect of the straight face and the fact that the first gear 40 can rotate in the sliding direction, the first gear 40 rotates, thereby driving the cutting rod 30 to rotate, so that the cutting knife 20 that has just completed cutting is flipped to the bottom.

[0055] A bracket 4 is fixedly connected to the annular groove 7, and a motor 5 is fixedly installed on the bracket 4. The transmission shaft of the motor 5 is fixedly connected to the worm 33. Starting the motor 5 can drive the worm 33 to rotate. Two limit plates 31 are fixedly connected to the annular groove 7. The four cutting knives 20 are respectively fitted with the two limit plates 31 in pairs. The limit plates 31 and the cutting knives 20 are fitted to form a limit constraint, which can effectively prevent the vibration generated when the two cutting knives 20 approach each other and collide with each other during cutting, causing the cutting rod 30 to rotate.

[0056] The transmission assembly is composed of a first transmission wheel 23, a second transmission wheel 12, a third transmission wheel 25, a fourth transmission wheel 14, a first belt 24, a second belt 26 and a third belt 13. The first transmission wheel 23 is the starting transmission component of the transmission system. The first transmission wheel 23 is rotatably connected to the ring groove 7. The second transmission wheel 12 receives and transmits the power of the first transmission wheel 23. The second transmission wheel 12 is rotatably connected to the processing box 2. The third transmission wheel 25 further transmits power to other components. The third transmission wheel 25 is rotatably connected to the seat 1. The fourth transmission wheel 14 transmits power to the corresponding The fourth transmission wheel 14 is rotatably connected to the base 1, the first belt 24 is used to connect the first transmission wheel 23 and the second transmission wheel 12 and transmit power, the first belt 24 is wound around the first transmission wheel 23 and the second transmission wheel 12, the second belt 26 is used to connect the second transmission wheel 12 and the third transmission wheel 25 and transmit power, the second belt 26 is wound around the second transmission wheel 12 and the third transmission wheel 25, the third belt 13 is used to connect the second transmission wheel 12 and the fourth transmission wheel 14 and transmit power, the third belt 13 is wound around the second transmission wheel 12 and the fourth transmission wheel 14.

[0057] In this embodiment, when the motor 5 drives the worm 33 to rotate, the worm wheel 34 can drive the bidirectional reciprocating screw rod 11 to rotate, so that the first slider 39 drives the first gear 40 and the cutting rod 30 to slide, so that the two cutting knives 20 are close to each other and then cut the heat transfer element. When the teeth of the first gear 40 contact the inclined saw teeth of the first rack 42, since the first gear 40 is a one-way bearing, it cannot rotate under the action of the first rack 42. When they are close to each other, the first rack 42 will compress the spring 41 downward. When the two cutting knives 20 move away from each other, the teeth of the first gear 40 contact the saw teeth of the first rack 42 directly. Due to the blocking effect of the direct surface and the ability of the first gear 40 to rotate in the sliding direction, the first gear 40 rotates, thereby driving the cutting rod 30 to rotate, so that the cutting knife 20 that has just completed cutting flips to the bottom, and the cutting knife 20 under the cutting rod 30 flips up to prepare for the next cutting. In this cycle, by changing the knife after cutting, the cutting knives 20 work alternately, which can effectively avoid continuous work of the knife and shorten its service life.

[0058] Embodiment 2:

[0059] Different from the first embodiment, Figure 1 and Figure 4 - Fig.10 , this embodiment also has the following further contents:

[0060] The grinding assembly consists of two first reciprocating screw rods 36, two second sliders 35 and two grinding blocks 43. The two first reciprocating screw rods 36 are respectively rotatably connected in the annular groove 7. The two second sliders 35 are respectively threadedly connected to the two first reciprocating screw rods 36. When the first reciprocating screw rods 36 rotate, the second sliders 35 can be driven to slide back and forth. The two second sliders 35 are respectively slidably connected in the annular groove 7, so that the second sliders 35 can slide smoothly. The two grinding blocks 43 are respectively fixedly connected to the two second sliders 35. When the second sliders 35 slide back and forth, the grinding blocks 43 can be driven to slide back and forth, thereby grinding the cutting knife 20 that has just completed the cutting work.

[0061] The uniform conveying and unloading assembly consists of a conveyor belt 8, two rotating shafts 21, a roller 9 and three baffles 10. One of the two rotating shafts 21 is rotatably connected in the processing box 2, and the other is rotatably connected to both sides of the base 1. The conveyor belt 8 is wound around the two rotating shafts 21. When one of the rotating shafts 21 rotates, the other rotating shaft 21 can be driven to rotate through the conveyor belt 8, thereby making the conveyor belt 8 work. The roller 9 is rotatably connected to the base 1, and the baffle 10 is fixedly connected to the roller 9, and can knock the components on the conveyor belt 8 back a certain distance.

[0062] It should be noted that the rolling processing area is below the conveying end of the conveyor belt 8.

[0063] A sieve plate 28 is fixedly connected inside the processing box 2, and one end of the sieve plate 28 extends to the outside of the outlet on one side of the processing box 2. The sieve plate 28 can screen out the components that are not fully sheared. The first transmission wheel 23 is fixedly connected to the worm gear 34. When the worm gear 34 rotates, it can drive the worm gear 34 to rotate. The second transmission wheel 12 is fixedly connected to the rotating shaft 21. When the second transmission wheel 12 rotates, it can drive the rotating shaft 21 to rotate. The fourth transmission wheel 14 is fixedly connected to the roller 9. When the fourth transmission wheel 14 rotates, it can drive the roller 9 to rotate.

[0064] In this embodiment, when the cutting knife 20 after cutting work is turned over to the bottom and slides to both sides at the same time, the first reciprocating screw 36 rotates under the drive of the worm 33. Since the sliding of the cutting knife 20 is driven by the worm wheel 34, and the worm and worm gear transmission has the characteristic of deceleration, that is, the worm wheel can only rotate a small angle for each rotation of the worm, which causes the rotation speed of the worm wheel 34 to be much lower than the rotation speed of the worm 33. Therefore, when the first reciprocating screw 36 rotates, the second slider 35 can drive the grinding block 43 to slide back and forth at high speed, so that the cutting knife 20 that has just completed the cutting work can be quickly polished when it slides to the gap at the grinding block 43, which is convenient for the next round of continued use. This can save time for manual maintenance of the tool and keep the cutting knife 20 in good condition all the time. Good working condition provides reliable guarantee for cutting quality. When the heat transfer element after shearing passes through the sieve plate 28 and falls onto the conveyor belt 8, the conveyor belt 8 can drive the cut heat transfer element to the rolling place under the rotation of the rotating shaft 21. At the same time, the roller 9 drives the baffle 10 to rotate. During the rotation of the baffle 10, the element will be pushed back due to the blocking effect of the baffle 10, temporarily preventing it from moving forward. When the baffle 10 continues to rotate and leaves the gap of the conveyor belt 8, the continuous operation of the conveyor belt 8 drives the element to be transported forward for a distance, so that the material can fall evenly from the conveyor belt 8 to the rolling place below, avoiding excessive concentration of elements, which may cause excessive local rolling force, resulting in excessive deformation of the element or cracks.

[0065] Embodiment three:

[0066] Reference Fig.11 - Fig.16 , compared with the first embodiment and the second embodiment, in this embodiment:

[0067] A first bevel gear 29 is rotatably connected to the base 1, and a second reciprocating screw rod 19 is fixedly connected to the first bevel gear 29. When the first bevel gear 29 rotates, it can drive the second reciprocating screw rod 19 to rotate. A top plate 15 is provided above the base 1, and a second reciprocating screw rod 19 is rotatably connected below the top plate 15, and a second sliding rod 18 is fixedly connected below the top plate 15.

[0068] The secondary processing component consists of a slide 22, two second gears 46, a delivery box 27 and a slide plate 44. The slide 22 is slidably connected to the second reciprocating screw 19 and the second slide bar 18. The two second gears 46 are respectively rotatably connected to the slide 22. The delivery box 27 is fixedly connected between the two second gears 46. When the second reciprocating screw 19 rotates, it can drive the slide 22, the two second gears 46 and the delivery box 27 to slide back and forth up and down. A slide groove is provided under the delivery box 27, and the slide plate 44 is slidably connected in the slide groove under the delivery box 27. Since the slide groove under the delivery box 27 is forward, when the angle of the delivery box 27 is deflected, the slide plate 44 will first slide and extend from under the delivery box 27.

[0069] Two sensors 3 are arranged on the outside of the processing box 2, and a solenoid valve is arranged at the opening on the outside of the processing box 2. When the sensor 3 senses that the delivery box 27 in front has left, a signal will be immediately transmitted to the control system, and the control system will then issue a command to control the solenoid valve to close the opening on the outside of the processing box 2 to prevent the insufficiently sheared components from sliding off the sieve plate 28 and out of the processing box 2 and scattering on the ground. When the sensor 3 senses the delivery box 27, the solenoid valve will be opened to allow the insufficiently sheared heat dissipating components on the sieve plate 28 to slide into the delivery box 27. There are two mounting holes fixedly connected below the top plate 15. The second racks 17 are respectively fixedly connected to the two mounting frames 16, and the second racks 17 are respectively meshed with the two second gears 46. When the second gear 46 slides to the second rack 17, under the action of the second rack 17, the second gear 46 can drive the delivery box 27 to rotate. The third transmission wheel 25 is fixedly connected with a second bevel gear 45, and the second bevel gear 45 is meshed with the first bevel gear 29. When the third transmission wheel 25 rotates, the first bevel gear 29 can be driven to rotate through the second bevel gear 45, thereby rotating the second reciprocating screw rod 19.

[0070] In this embodiment, when the heat transfer element after cutting falls onto the sieve plate 28, since the sieve plate 28 is obliquely arranged in the processing box 2, the heat transfer element that is not fully cut will slide along the sieve plate 28 into the delivery box 27. Under the rotation of the second reciprocating screw 19, the delivery box 27 slides forward. When the sensor 3 detects that the delivery box 27 leaves, the solenoid valve is controlled to close the opening of the processing box 2 to prevent the subsequent heat transfer element that is not fully cut from sliding out. Subsequently, under the action of the second rack 17, the second gear 46 drives the delivery box 47 to rotate. Since the chute below the delivery box 27 is located forward, when the angle of the delivery box 27 is When deflected, the slide plate 44 will first slide out from under the delivery box 27, and the slide plate 44 will slide out under the action of gravity, and then the heat transfer elements that have not been fully sheared will slide through the slide plate 44 into the hopper 6 for re-shearing, and finally, under the action of the second reciprocating screw 19, the delivery box 27 will slide back downward, and the second gear 46 will drive the delivery box 27 to rotate in the opposite direction under the action of the second rack 17, and the slide plate 44 will be retracted, and the delivery box 27 will slide to the bottom to collect the elements that have not been fully sheared again, and this cycle can make the heat transfer elements fully sheared, effectively improving the processing quality of the heat transfer elements.
