Description

Technical Field

[0002] Auto parts are the various units that make up the whole car and a kind of product that serves the car. With the improvement of people's living standards, people's consumption on cars is increasing, and the market for auto parts is becoming larger and larger.

[0003] At present, some auto parts are made of pipes during production, which usually need to be cut into a certain length to facilitate subsequent processing and assembly. The existing pipes used for auto parts manufacturing are usually cut manually using electric saws, which is time-consuming and labor-intensive, and cannot be cut continuously in large quantities, resulting in low production efficiency. In addition, manual cutting cannot make the length of each section of the pipe equal, resulting in a large error, thereby reducing product quality. In addition, a large amount of metal debris is generated during the cutting process, and the metal debris is splashed everywhere, which requires manual cleaning later, which is troublesome. In addition, the splashed metal debris may cause accidental injuries to surrounding workers, resulting in low safety.

[0019] S2. During the cutting process, the coolant in the pump liquid chamber will be sprayed onto the surface of the cutter of the cutting machine through multiple spray holes to cool the cutter, and the fan blades will rotate quickly to generate suction force to draw the debris and dust generated by cutting into the dust collection box, so that the working environment remains clean;

[0020] S3. During the cutting process, the reciprocating swing of the driving rod will synchronously push the pipe on the first guide rail to move a certain distance, and the travel distance each time is equal, so that the pipe can be fed synchronously at equal distances, and then the pipe can be cut continuously and equidistantly automatically;

[0021] S4. The cut pipes will be pushed onto the second rail, and subsequent staff can take the pipes on the second rail for storage.

[0022] The present invention has the following beneficial effects:

[0023] 1. By setting up the cutting mechanism, the driving motor rotates, driving the driving rod to swing up and down, and then driving the cutting machine to move up and down, and pushing the material synchronously, the pipe can be cut continuously and in equal lengths. Compared with manual cutting, it saves time and effort, and has higher cutting accuracy;

[0024] 2. By setting an electric push rod, driving the electric push rod, driving the mounting block to slide, thereby changing the eccentric position of the limit rod, when the limit rod is closer to the edge position of the first gear, the span of the L-shaped rod driven by the drive rod to move up and down will be larger, and then in a single reciprocating, more air will be pumped into the drive cylinder, so that the sliding plug moves a longer distance, and then the push plate moves a longer distance in a single time, and the pipe moves a longer distance, and then the length of the cut pipe will be longer, on the contrary, the length of the cut pipe will be shorter, so the length of the cut pipe can be adjusted according to the actual situation, and the scope of application is wider;

[0025] 3. By setting the conductive block and the resistance bar, when cutting pipes of different thicknesses, when the pipe is placed on the first guide rail, if the pipe is thicker, the distance between the two first clamping plates will be larger, and then the distance between the two connecting rods will also be larger. When cutting thicker pipes, since the force area is larger during cutting, the descending speed of the cutting machine should be slower during cutting. If the descending speed is too fast, the pipe may not be cut in place, causing the pipe to curl or the cutter of the cutting machine to break. Therefore, when cutting thicker pipes, the conductive block will be closer to the edge of the base, and then the resistance of the resistance bar connected to the circuit will be larger, the current in the circuit will be smaller, and then the speed of the motor will be slower. At this time, the speed of the cutting machine moving up and down will slow down, thereby reducing the cutting speed, ensuring that the cutting is in place, improving the cutting effect, and reducing the damage rate of the pipe;

[0026] 4. By setting a cooling mechanism, during the cutting process, when the driving rod moves downward to drive the cutting machine to move downward to cut the pipe, the driving rod will synchronously drive the L-shaped rod to move downward, and then drive the slide to move downward, and the coolant in the pump liquid cavity will enter the annular cavity through the one-way liquid outlet pipe, and then the coolant will be sprayed onto the surface of the cutting machine cutter through multiple spray holes to cool the cutter and reduce the loss of the cutter. Due to the high-speed rotation of the cutter, the coolant adhering to the surface of the cutter will be subjected to a large centrifugal force, and then the coolant will flow from the inside to the outside on the surface of the cutter, and then cover the entire surface of the cutter, so that the cutter dissipates heat evenly and improves the cooling effect;

[0027] 5. By setting up a dust removal mechanism, the rotation of the first gear will synchronously drive the rotation of the second gear, and then drive the second rotating rod to rotate, drive multiple fan blades to rotate rapidly, generate suction force, and then the debris generated during the cutting process will be sucked into the dust box through multiple dust suction holes, and then the debris will enter the dust box through the dust suction pipe, and be intercepted by the filter and stored in the dust box, thereby preventing the debris from splashing and accidentally injuring workers, providing production safety, and the debris can also be recycled to reduce resource waste.

[0039] Reference Figure 1 - Fig. 9 , a pipe cutting device for automobile parts manufacturing, comprising a base 1;

[0040] The cutting mechanism includes a mounting plate 2 fixedly connected to the upper end of the base 1, the side wall of the mounting plate 2 is rotatably connected with a rotating shaft 3, the side wall of the rotating shaft 3 is fixedly connected with a first gear 4, the side wall of the first gear 4 is provided with a mounting groove 5, the inner wall of the mounting groove 5 is slidably connected with a mounting block 6, the bottom of the mounting groove 5 is fixedly connected with an electric push rod 7, the movable end of the electric push rod 7 is fixedly connected to the mounting block 6, the side wall of the mounting plate 2 is rotatably connected with a first rotating rod 8, the side wall of the first rotating rod 8 is fixedly connected with a driving rod 9, the other end of the driving rod 9 is fixedly connected with a mounting seat 10, the inner wall of the mounting seat 10 is installed with a cutting machine 11, the side wall of the mounting block 6 is fixedly connected with a limiting rod 12, the side wall of the driving rod 9 is provided with a limiting groove 13, and the side wall of the limiting rod 12 is slidably connected to the inner wall of the limiting groove 13.

[0041] An equidistant feeding mechanism is installed on the base 1, and the equidistant feeding mechanism includes a first guide rail 26 and a second guide rail 27 fixedly connected to the upper end of the base 1 through a fixed shaft, the lower end of the first guide rail 26 is fixedly connected to the driving cylinder 14, the inner wall of the driving cylinder 14 is sealingly and slidably connected to the sliding plug 15, the side wall of the sliding plug 15 is fixedly connected to the push rod 16, the other end of the push rod 16 penetrates the side wall of the driving cylinder 14 and is fixedly connected to the push plate 17, and a first spring 151 is fixedly connected between the sliding plug 15 and the inner wall of the driving cylinder 14.

[0042] The equidistant feeding mechanism also includes a box body 18 fixedly connected to the upper end of the mounting plate 2 through a fixed shaft, and a slide plate 19 is sealed and slidably connected to the inner wall of the box body 18, and the slide plate 19 divides the interior of the box body 18 into two parts: a pump air chamber 191 and a pump liquid chamber 192. A one-way air inlet pipe 20 is fixedly connected to the inner wall of the pump air chamber 191, and the one-way air inlet pipe 20 only allows external air to enter the pump air chamber 191. The pump air chamber 191 is connected to the drive cylinder 14 through a one-way air outlet pipe 21, and the one-way air outlet pipe 21 only allows air in the pump air chamber 191 to enter the drive cylinder 14. A vent hole 22 is provided on the inner wall of the drive cylinder 14, and a pressure relief valve is installed on the inner wall of the vent hole 22. An L-shaped rod 24 is fixedly connected to the lower end of the slide plate 19, and the lower end of the L-shaped rod 24 passes through the lower end of the box body 18. A slide groove 23 is provided on the side wall of the drive rod 9, and the side wall of the L-shaped rod 24 is slidably connected to the inner wall of the slide groove 23.

[0043] It should be noted that when the pipe is pushed, the side wall of the cutter of the cutting machine 11 is still in contact with the pipe. When air is pumped into the driving cylinder 14, the push plate 17 cannot push the pipe to move. As a result, the pressure in the driving cylinder 14 will exceed the threshold of the pressure relief valve, and the pressure relief valve will open to release air and pressure to ensure the normal movement of the cutting machine 11.

[0044] A motor 25 is fixedly connected to the side wall of the mounting plate 2 , and an output end of the motor 25 passes through the side wall of the mounting plate 2 and is fixedly connected to the rotating shaft 3 .

[0045] The side walls of the first guide rail 26 and the second guide rail 27 are symmetrically and slidingly connected with two connecting rods 28, one end of the two connecting rods 28 extends into the first guide rail 26 and is fixedly connected with a first clamping plate 29, and the other ends of the two connecting rods 28 extend into the second guide rail 27 and are fixedly connected with a second clamping plate 30, and the side walls of the connecting rods 28 are sleeved with second springs 31, and the two ends of the second springs 31 are fixedly connected to the inner wall of the first guide rail 26 and the side walls of the first clamping plate 29 respectively.

[0046] Further, the driving motor 25 rotates, driving the rotating shaft 3 to rotate, and then driving the first gear 4 to rotate, driving the limiting rod 12 to rotate eccentrically, and under the action of the limiting rod 12, the driving rod 9 will be driven to swing up and down, and then the cutting machine 11 will move up and down in an arc. When the driving rod 9 swings upward, it will drive the L-shaped rod 24 to move upward, and then drive the slide plate 19 to move upward. At this time, the air in the pump air cavity 191 enters the driving cylinder 14 through the one-way air outlet pipe 21, thereby pushing the sliding plug 15 to move a distance to the right (as shown in the attached figure). Figure 3 As shown), the push rod 16 is driven to move, the push plate 17 is driven to move a certain distance, and the pipe is pushed to move a certain distance. When the cutting machine 11 moves downward, the pipe is cut. Since the swing amplitude of the driving rod 9 is the same each time, the same amount of air is pumped into the driving cylinder 14 each time, so that the distance traveled by the push plate 17 is equal each time, the length of the pushed pipe will also be the same, and the length of the cut pipe will be equal, thereby realizing continuous equidistant cutting. Compared with manual cutting, it is more time-saving and labor-saving, and the cutting accuracy is higher.

[0047] It is worth mentioning that when it is necessary to adjust the length of the cut pipe, it is only necessary to drive the electric push rod 7 to drive the mounting block 6 to slide, thereby changing the eccentric position of the limit rod 12. When the limit rod 12 is closer to the edge position of the first gear 4, the span of the L-shaped rod 24 driven by the drive rod 9 to move up and down will be larger, and then during a single reciprocating motion, more air will be pumped into the drive cylinder 14, which will make the sliding plug 15 move a longer distance, and then make the push plate 17 move a longer distance in a single movement, and make the pipe move a longer distance, and then the cut pipe length will be longer, on the contrary, the cut pipe length will be shorter. Therefore, the cut pipe length can be adjusted according to actual conditions, and the scope of application is wider.

[0048] A resistor bar 38 is fixedly connected to the upper end of the base 1, and a conductive block 37 cooperating with the resistor bar 38 is fixedly connected to the lower end of one of the connecting rods 28. The motor 25, the conductive block 37, the resistor bar 38 and the external power supply are electrically connected via wires. An exhaust hole 39 is opened on the inner wall of the driving cylinder 14, and an electromagnetic valve is installed on the inner wall of the exhaust hole 39. The electromagnetic valve is electrically connected to the motor 25 via a wire.

[0049] Furthermore, when cutting pipes of different thicknesses, when the pipes are placed on the first guide rail 26, if the pipes are thicker, the distance between the two first clamps 29 will be larger, and thus the distance between the two connecting rods 28 will also be larger. When cutting thicker pipes, since the force area is larger during cutting, the descending speed of the cutting machine 11 should be slower during cutting. If the descending speed is too fast, the pipe may not be cut into place, causing the pipe to curl or the cutter of the cutting machine 11 to break. Therefore, when cutting thicker pipes, the conductive block 37 will be closer to the edge of the base 1, and thus the resistance of the resistor bar 38 connected to the circuit will be larger, the current in the circuit will be smaller, and then the rotation speed of the motor 25 will be slower. At this time, the speed of the cutting machine 11 moving up and down will slow down, thereby reducing the cutting speed, ensuring that the cutting is in place, improving the cutting effect, and reducing the damage rate of the pipe.

[0050] A cooling mechanism is installed on the mounting base 10, and the cooling mechanism includes an annular cavity 32 opened in the mounting base 10, and a plurality of liquid spray holes 33 are opened on the inner wall of the annular cavity 32. A one-way liquid inlet pipe 34 is fixedly connected to the inner wall of the pump liquid cavity 192, and the other end of the one-way liquid inlet pipe 34 is connected to an external container storing coolant. The pump liquid cavity 192 is connected to the annular cavity 32 through a one-way liquid outlet pipe 35, and the one-way liquid outlet pipe 35 only allows the coolant in the pump liquid cavity 192 to enter the annular cavity 32.

[0051] Furthermore, during the cutting process, when the driving rod 9 moves downward to drive the cutting machine 11 to move downward to cut the pipe, the driving rod 9 will synchronously drive the L-shaped rod 24 to move downward, and then drive the slide plate 19 to move downward, and the coolant in the pump liquid chamber 192 will enter the annular chamber 32 through the one-way liquid outlet pipe 35, and then the coolant will be sprayed onto the surface of the cutter of the cutting machine 11 through multiple spray holes 33, so as to cool down the cutter and reduce the loss of the cutter. Due to the high-speed rotation of the cutter, the coolant adhering to the surface of the cutter will be subjected to a large centrifugal force, and then the coolant will flow from the inside to the outside on the surface of the cutter, and then cover the entire surface of the cutter, so that the cutter dissipates heat evenly and improves the cooling effect.

[0052] A dust removal mechanism is installed on the base 1, and the dust removal mechanism includes a dust box 40 fixedly connected to the upper end of the base 1, and a plurality of dust collection holes 41 are opened on the inner wall of the dust box 40. A dust box 42 is fixedly connected to the upper end of the base 1 through a fixed shaft, and a second rotating rod 43 is rotatably connected to the inner wall of the dust box 42. A plurality of fan blades 44 are fixedly connected to the side wall of the second rotating rod 43, and the dust box 42 is connected to the dust box 40 through a dust collection pipe 45.

[0053] The dust removal mechanism also includes an exhaust hole 46 opened on the inner wall of the dust box 42, a filter 47 is fixedly connected to the inner wall of the dust box 42, one end of the second rotating rod 43 passes through the side wall of the dust box 42 and is fixedly connected to a second gear 48, and the second gear 48 is meshed with the first gear 4.

[0054] Furthermore, the rotation of the first gear 4 will synchronously drive the second gear 48 to rotate, and then drive the second rotating rod 43 to rotate, and drive the multiple fan blades 44 to rotate rapidly, generating a suction force, and the debris generated during the cutting process will be sucked into the dust box 40 through the multiple dust holes 41, and then the debris will enter the dust box 42 through the dust pipe 45, and be intercepted by the filter 47 and stored in the dust box 42, thereby preventing the debris from splashing and accidentally injuring workers, providing production safety, and the debris can also be recycled to reduce resource waste.

[0055] A method for cutting a pipe for manufacturing automobile parts comprises the following steps:

[0056] S1. First, place the pipe on the first guide rail 26, then start the motor 25 and start the cutting machine 11 simultaneously. The motor 25 can drive the driving rod 9 to swing up and down, thereby driving the cutting machine 11 to move up and down to cut the pipe;

[0057] S2. During the cutting process, the coolant in the pump liquid chamber 192 will be sprayed onto the cutter surface of the cutting machine 11 through the multiple spray holes 33 to cool the cutter, and the fan blades 44 will rotate rapidly to generate suction force to draw the debris and dust generated by cutting into the dust box 42, so that the working environment remains clean and tidy;

[0058] S3. During the cutting process, the reciprocating swing of the driving rod 9 will synchronously push the pipe on the first guide rail 26 to move a certain distance, and the distance of each movement is equal, so that the pipe can be fed synchronously at equal distances, and then the pipe can be automatically cut continuously at equal distances;

[0059] S4. The cut pipes will be pushed onto the second guide rail 27, and subsequent staff can take the pipes on the second guide rail 27 away for storage.

[0060] In the present invention, the pipe to be cut is placed on the first guide rail 26, and the first clamp 29 will clamp and fix the pipe under the action of the second spring 31. Since the first clamp 29 and the second clamp 30 are connected by the connecting rod 28, the second clamp 30 will move with the first clamp 29, so as to facilitate the cut pipe to enter the second guide rail 27. Then the driving motor 25 is rotated (at this time, the solenoid valve installed on the inner wall of the exhaust hole 39 is powered on and closed), driving the rotating shaft 3 to rotate, and then driving the first gear 4 to rotate, driving the limit rod 12 to rotate eccentrically, and under the action of the limit rod 12, it will drive the driving rod 9 to swing up and down, and then drive the cutting machine 11 to move in an arc up and down.

[0061] When the driving rod 9 swings upward, it drives the L-shaped rod 24 to move upward, and then drives the slide plate 19 to move upward. At this time, the air in the pump air chamber 191 enters the driving cylinder 14 through the one-way air outlet pipe 21, thereby pushing the slide plug 15 to move to the right for a distance (as shown in the attached figure). Figure 3 As shown in the figure), the push rod 16 is driven to move, the push plate 17 is driven to move a certain distance, and the pipe is pushed to move a certain distance. When the cutting machine 11 moves downward, the pipe is cut. Since the swing amplitude of the driving rod 9 is the same each time, the same amount of air is pumped into the driving cylinder 14 each time, so that the distance traveled by the push plate 17 is equal each time, the length of the pushed pipe is also the same, and the length of the cut pipe is equal, thereby achieving continuous equidistant cutting. Compared with manual cutting, it is more time-saving and labor-saving, and the cutting accuracy is higher. When the push plate 17 moves to the rightmost position (as shown in the figure), the push plate 17 moves to the rightmost position (as shown in the figure), and the push plate 17 moves to the rightmost position (as shown in the figure). Figure 3 As shown), the motor 25 is powered off, and the solenoid valve on the inner wall of the exhaust hole 39 is powered off and opened, and the air in the drive cylinder 14 is discharged through the exhaust hole 39, and then the slide plug 15 is reset under the action of the first spring 151, driving the push plate 17 to reset and perform the next cutting.

[0062] During the cutting process, when the driving rod 9 moves downward to drive the cutting machine 11 to move downward to cut the pipe, the driving rod 9 will synchronously drive the L-shaped rod 24 to move downward, and then drive the slide plate 19 to move downward, and the coolant in the pump liquid chamber 192 will enter the annular chamber 32 through the one-way liquid outlet pipe 35, and then the coolant will be sprayed onto the surface of the cutter of the cutting machine 11 through multiple spray holes 33, so as to cool down the cutter and reduce the loss of the cutter. Due to the high-speed rotation of the cutter, the coolant adhering to the surface of the cutter will be subjected to a large centrifugal force, and then the coolant will flow from the inside to the outside on the surface of the cutter, and then cover the entire surface of the cutter, so that the cutter dissipates heat evenly and improves the cooling effect.

[0063] In addition, the rotation of the first gear 4 will synchronously drive the second gear 48 to rotate, and then drive the second rotating rod 43 to rotate, and drive the multiple fan blades 44 to rotate rapidly, generating a suction force, and the debris generated during the cutting process will be sucked into the dust box 40 through the multiple dust holes 41, and then the debris will enter the dust box 42 through the dust pipe 45, and be intercepted by the filter 47 and stored in the dust box 42, thereby preventing the debris from splashing and accidentally injuring workers, providing production safety, and the debris can also be recycled to reduce resource waste.

[0064] When it is necessary to adjust the length of the cut pipe, it is only necessary to drive the electric push rod 7 to drive the mounting block 6 to slide, thereby changing the eccentric position of the limit rod 12. When the limit rod 12 is closer to the edge position of the first gear 4, the span of the L-shaped rod 24 driven by the drive rod 9 to move up and down will be larger, and then during a single reciprocating motion, more air will be pumped into the drive cylinder 14, thereby making the sliding plug 15 move a longer distance, thereby making the push plate 17 move a longer distance in a single motion, thereby making the pipe move a longer distance, thereby making the cut pipe length longer, and conversely, the cut pipe length shorter. Therefore, the cut pipe length can be adjusted according to actual conditions, and the scope of application is wider.

[0065] When cutting pipes of different thicknesses, when the pipes are placed on the first guide rail 26, if the pipes are thicker, the distance between the two first clamps 29 will be larger, and then the distance between the two connecting rods 28 will also be larger. When cutting thicker pipes, since the force area is larger during cutting, the descending speed of the cutting machine 11 should be slower during cutting. If the descending speed is too fast, the pipe may not be cut in place, causing the pipe to curl or the cutter of the cutting machine 11 to break. Therefore, when cutting thicker pipes, the conductive block 37 will be closer to the edge of the base 1, and then the resistance of the resistor bar 38 connected to the circuit will be larger, the current in the circuit will be smaller, and then the speed of the motor 25 will be slower. At this time, the speed of the cutting machine 11 moving up and down will slow down, thereby reducing the cutting speed, ensuring that the cutting is in place, improving the cutting effect, and reducing the damage rate of the pipe.
