Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting equipment, in particular to a cutting piece service life testing device with dust removal function. BACKGROUND

[0002] Metal rod cutting is a common metal processing operation process, but there are a series of problems to be solved in the existing technology in the industrial production process of metal rod cutting.

[0003] On the one hand, the cutting knife faces serious challenges in the use process; with the increase of cutting times, the cutting knife will gradually wear, which will lead to many adverse consequences; in terms of cutting speed, the cutting ability of the worn cutting knife decreases, which significantly slows down the cutting speed of the metal rod, seriously affecting the efficiency of the entire processing flow; in terms of cutting surface quality, the originally smooth cutting surface becomes rough due to the wear of the cutting knife, with burrs, scratches and other defects, which has a great negative impact on the product quality in the precision machining field, thereby causing great difficulties in the subsequent processing link, and even causing the product to be scrapped; more dangerously, the excessively worn cutting knife will be blunt and bear uneven cutting force during cutting, which is easy to crack; the fragments produced by cracking will splash, which not only damages the metal rod being processed, but also poses a serious threat to the safety of surrounding equipment and personnel, such as fragments flying into key parts of the equipment may cause equipment failure, and hitting the operator may cause personal injury. However, there is a lack of effective cutting knife service life testing device in the current technical field, which can only rely on experience or regular replacement of cutting knives, which is blind and may cause waste of cost due to early replacement, or may cause a series of quality and safety problems due to untimely replacement;

[0004] On the other hand, a large amount of metal debris and waste dust will be generated during the cutting process of the metal rod; these metal waste dust particles suspended in the air will cause the concentration of inhalable particulate matter in the air to increase, and workers in this environment for a long time will inhale a large amount of dust, which will cause strong irritation to the respiratory tract, thereby causing symptoms such as coughing and wheezing, and increasing the risk of respiratory diseases such as bronchitis and pneumoconiosis; secondly, the reduction of visibility is also a prominent problem, which will interfere with the judgment of workers on the cutting progress and quality; in addition, the pollution problem of equipment and working area cannot be ignored; the waste dust will fall on the surface of the cutting machine, workbench and surrounding tools, etc. For the equipment, the dust accumulated in the cooling fins or air vents of the key components such as the motor of the cutting machine will hinder heat dissipation, affect the heat dissipation performance, and thus cause overheating of the equipment and shorten the service life of the equipment; at the same time, the pollution of the working area will increase the cleaning burden, and if not cleaned in time, the dust will accumulate more and more, which will not only reduce the work efficiency, but also pollute other workpieces being processed.

[0018] As improved, the pneumatic valve is connected with an air pump to cooperate with the cutting work of the metal rod.

[0019] Compared with the prior art, the cutting piece service life test device with dust removal function has the following beneficial effects:

[0020] 1、The service life of the cutting piece can be effectively tested through the design of the service life test assembly; the service life of the cutting piece can be indirectly understood through the pressure value feedback of the pressure sensor on the S-shaped piece, that is, when the cutting piece has too large cutting reaction force, it actually indicates that the cutting piece has been seriously worn out during cutting, and the above detection work can bring the following benefits:

[0021] Improve the cutting quality and ensure the flatness of the cutting surface: the service life of the cutting knife is tested by monitoring the reaction force of the cutting piece, and the wear condition of the cutting piece can be found in time; when the reaction force is too large, it indicates that the cutting piece is seriously worn out at this time, so the cutting piece is replaced or repaired in time to avoid cutting with excessively worn cutting pieces, thereby ensuring the flatness of the cutting surface; the flat cutting surface can meet the requirements of high-quality products and reduce the repair or reprocessing of the cutting surface in the subsequent processing process;

[0022] Improve work efficiency and maintain stable cutting speed: the component can monitor the wear degree of the cutting piece to avoid excessive wear of the cutting piece and reduce the cutting ability, thereby maintaining a relatively stable cutting speed; in industrial production, stable cutting speed is very important for ensuring the efficient operation of the entire production process. For example, in large-scale metal pipe cutting for building water supply and drainage system production, stable cutting speed helps to complete the order task on time and improves the timeliness of production;

[0023] Reduce equipment failure and maintenance time: timely detection of cutting blade wear can prevent cutting blade cracking; cutting blade cracking and debris can damage equipment, causing equipment failure and downtime maintenance; by using the assembly, equipment failure caused by cutting blade problems can be reduced, equipment maintenance time can be shortened, equipment effective operation time can be improved, overall work efficiency can be improved, and the harm of debris flying to the operator can be effectively avoided, and the personal safety of the operator can be protected.

[0024] 2、The present application improves the overall safety of the equipment by adding an S-shaped part, which can improve the stability of the pressure sensor in the life test assembly under the action of the S-shaped part; reduce production interruptions caused by sudden failures, improve the continuity of the production process, and improve the use of the device; The benefits are as follows:

[0025] Protect the cutting blade: in the case of a faulty pressure sensor that cannot accurately detect the degree of cutting blade wear, if the cutting blade is severely worn and continues to cut the metal rod, the S-shaped part can play a buffering role under the action of its S-shaped shape; it can effectively reduce the excessive pressure on the cutting blade during cutting, prevent the cutting blade from breaking down due to forced cutting, prolong its service life, and reduce the cost of frequent replacement;

[0026] Protect the internal components of the machine: when the cutting blade continues to cut due to excessive wear, an abnormal impact force is generated, which is transmitted to the internal components of the device, specifically to the components of the auxiliary assembly, but the S-shaped buffer can absorb and disperse these impact forces through buffering, preventing damage to other components inside the device; At the same time, this dispersion of force also prevents the cutting blade from breaking down due to forced cutting, and the broken cutting blade fragments can cause passive damage to the components in the machine; this also helps to maintain the stability and integrity of the overall structure of the device, reduces the risk of device failure due to local damage, reduces maintenance costs and downtime.

[0027] 3、The present application can effectively collect and process the debris and metal dust generated when the cutting blade cuts the metal rod through the design of the waste dust treatment assembly; the integrated design of cutting and waste dust treatment has the following benefits:

[0028] Improve the working environment and improve air quality: the assembly can collect debris and waste dust during cutting, effectively reduce the concentration of metal dust particles in the air, avoid workers inhaling a large amount of dust, reduce irritation to the respiratory tract, reduce the occurrence of coughing and wheezing symptoms, and reduce the risk of respiratory diseases such as bronchitis and pneumoconiosis;

[0029] Improve visibility and reduce equipment and working area pollution: by collecting waste dust, it can prevent the working area visibility from being reduced due to a large amount of waste dust, and workers can see the cutting site more clearly, which is beneficial to observation to ensure cutting progress and quality; collect waste dust in time to avoid it falling on the surface of the equipment and the working area, prevent metal waste dust from accumulating to affect the heat dissipation performance of the equipment, ensure the normal heat dissipation of the cutting machine motor and other key components, prolong the service life of the equipment; At the same time, it reduces the cleaning workload and avoids the accumulation of dust affecting work efficiency and polluting other workpieces;

[0030] Enhance work safety and reduce fire and explosion risk: The assembly collects waste dust to prevent metal waste dust from contacting the skin and eyes of workers, preventing skin allergies, swelling, and eye pain, inflammation, and vision damage problems; It can avoid too high concentration of metal dust in the air; In the case of sparks generated during cutting metal rods causing explosions, eliminate the hidden danger of dust explosion, and protect personnel and equipment from serious damage caused by explosions.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0045] The present application will be further described in detail below according to the drawings and embodiments.

[0046] Embodiment: please refer to Figure 1 、 Figures 4 to 6 as shown:

[0047] To solve the problems mentioned in the technical solutions, the embodiment of the present application provides a cutting piece service life test device with dust removal function, which comprises: a machine body 1, a storage box 2, a cutting machine 301, a cutting piece 302, a metal rod 4, the storage box 2 is placed on one side of the machine body 1, the cutting piece 302 is fixedly connected to the bottom end of the cutting machine 301, the cutting machine 301 is arranged in the machine body 1, and the machine body 1 is divided into a cutting area and a waste dust processing area by a partition 101, a metal rod 4, a service life test assembly 5 and a waste dust processing assembly 6, the partition 101 is fixedly connected to the inner cavity of the machine body 1, the machine body 1 is divided into a cutting area and a waste dust processing area by the partition 101, the service life test assembly 5 and the auxiliary assembly 7 are in the cutting area, and the waste dust processing assembly 6 is in the waste dust processing area of the partition 101.

[0048] The service life test assembly 5 is used for detecting / testing the cutting life of the cutting piece 302; the inner cavity of the machine body 1 is fixedly connected with a track 501, one side of the track 501 is provided with a hinge 502, the track 501 is slidably connected with a driving sliding block 503 and a driven sliding block 504, the driving sliding block 503 is located above the driven sliding block 504, an S-shaped piece 505 is arranged between the driving sliding block 503 and the driven sliding block 504, both ends of the S-shaped piece 505 are fixedly connected with pressure sensors 506, and the two pressure sensors 506 are fixedly connected with the driving sliding block 503 and the driven sliding block 504 respectively.

[0049] Among them:

[0050] The bottom of the machine body 1 is a cavity, which can be used for cutting waste and transferring waste debris.

[0053] The life test assembly 5 is used for detecting / testing the cutting life of the cutting blade 302.

[0054] The hinge 502 is connected by external control, and is mainly used for driving the active slider 503 and the passive slider 504 to move on the track 501.

[0055] The active slider 503 and the passive slider 504 are adapted to slide on the track 501.

[0061] Among them: ​

[0062] The waste dust treatment assembly 6 is used to transfer the debris and waste dust generated during cutting, and to ensure the safety of the mechanical parts and personnel during cutting.

[0063] The collecting cover 601 is in communication with the cavity opened at the bottom of the machine body 1.

[0064] The filter plate 603 and the secondary filter cylinder 604 are mainly used to filter and isolate the debris and waste dust during cutting.

[0065] Further embodiments are shown in Figure 2 , Figure 3 .

[0066] The auxiliary assembly 7 is used for the transfer and fixation of the metal rod 4, and assists the service life test assembly 5 and the waste dust treatment assembly 6. The auxiliary assembly 7 comprises a supporting wheel part 701 fixed in the inner cavity of the machine body 1. The supporting wheel part 701 is provided with a driving device 702 on one side. The driving device 702 is fixedly connected with a guide block 703 on one side. The metal rod 4 is transferred by the supporting wheel part 701 and the driving device 702. The supporting wheel part 701 is fixedly connected with a support frame 704 on one side. The support frame 704 is fixedly connected with a pneumatic valve 705. The support frame 704 is vertically slidably connected with an N-shaped fixing part 706. The inner cavity of the machine body 1 is fixedly connected with an inclined surface transfer frame 707 on the side away from the supporting wheel part 701 of the support frame 704.

[0067] Among them:

[0068] The auxiliary assembly 7 is used for the transfer and fixation of the metal rod 4, and assists the service life test assembly 5 and the waste dust treatment assembly 6.

[0069] The driving device 702 comprises a driving wheel and a driving motor.

[0070] The guide block 703 is mainly used for stable and guided conveying of the metal rod 4.

[0071] The pneumatic valve 705 is connected with an air pump, so as to control the cooperation of the N-shaped fixing part 706 and the support frame 704 to fix the conveyed metal rod 4.

[0072] The inclined surface transfer frame 707 is mainly used for transferring the metal rod 4 cut by the cutting blade 302.

[0073] The working principles of all the above embodiments are as follows:

[0074] In the initial state:

[0075] The cutting blade 302 on the cutting machine 301 is not in contact with the metal rod 4. The metal rod 4 is located between the supporting wheel part 701 and the driving device 702, and is conveyed by the cooperation of the supporting wheel part 701 and the driving device 702.

[0076] The following is the working process of auxiliary component 7:

[0077] In use, the operator inserts the metal rod 4 horizontally into the machine body 1, positioning it between the support wheel 701 and the drive wheel of the drive device 702. (See attached diagram.) Figure 3 During use, the metal rod 4, conveyed by the support wheel 701 and the drive device 702, enters the area where the support frame 704 and the N-shaped fixing member 706 are located. Under the action of the air pump connected to the pneumatic valve 705, the N-shaped fixing member 706 can work with the support frame 704 to perform a reciprocating operation of fixing and releasing the metal rod 4. Specifically, when the N-shaped fixing member 706 works with the support frame 704 to fix the metal rod 4, the cutting blade 302 on the cutting machine 301 can cut the metal rod 4. The cut part of the metal rod 4 will fall onto the inclined transfer frame 707 and be transferred to the storage box 2 placed on one side of the machine body 1. When the N-shaped fixing member 706 no longer fixes the metal rod 4, the drive wheel on the support wheel 701 and the drive device 702 will convey the metal rod 4 again to ensure the subsequent cutting work of the cutting machine 302 on the cutting machine 301.

[0078] Please refer to the above work process. Figure 2 , Figure 3 .

[0079] The following is the working process of life test component 5:

[0080] For further details, please refer to the appendix. Figure 5 When cutting the metal bar 4, as the active slider 503 moves along the track 501 via the hinge 502, due to the interconnection of the components, the moving active slider 503 moves downwards together with the pressure sensor 506, S-shaped component 505, and passive slider 504, which are also sliding on the track 501. This causes the cutting machine 301 to move downwards synchronously, gradually bringing the cutting blade 302 closer to and ultimately in contact with the metal bar 4 below. During contact and cutting, the metal bar... 4 will have a reaction force on the cutting disc 302. Under the action of the reaction force, the cutting disc 302 will indirectly transmit the reaction force to the pressure sensors 506 at both ends of the S-shaped part 505 between the active slider 503 and the passive slider 504. At this time, the pressure sensor 506 will transmit the measured value to the device control and compare the value with the value fed back when the cutting disc 302 cuts the metal bar 4 in accordance with the process requirements. In this way, it can be determined whether the cutting disc 302 is severely worn.

[0081] Need to explain: if the cutting piece 302 cutting reaction force is too large, it actually means that the cutting piece 302 has been seriously worn during cutting, cutting force is blocked; the design of pressure feedback and comparison can effectively measure the state of the cutting piece 302;

[0082] Further, by adding S-shaped piece 505, under the action of its S shape, when the pressure sensor 506 in the life test assembly 5 appears unstable use, it can improve the overall use safety of the equipment; reduce the production interruption caused by sudden failure, improve the continuity of the production process, and perfect the use of the device. The drawbacks; the benefits are as follows:

[0083] Protect the cutting piece 302: in the case of failure of the pressure sensor 506, it cannot accurately detect the wear degree of the cutting piece 302, if the cutting piece 302 has been seriously worn and continues to cut the metal rod 4, the S-shaped piece 505 can play a buffering role under the action of its S shape; it can effectively reduce the excessive pressure on the cutting piece 302 during cutting, avoid the cutting piece 302 from collapsing due to forced cutting, prolong its service life, and reduce the cost of frequent replacement;

[0084] Protect the internal components of the machine body 1: when the cutting piece 302 continues to cut due to excessive wear, an abnormal impact force is generated, which will be transmitted to the internal components of the device, specifically to the components of the auxiliary assembly 7, but the S-shaped buffer can absorb and disperse these impact forces through the buffering effect, preventing them from causing damage to other components inside the device; At the same time, this dispersion of force also avoids the cutting piece 302 from collapsing due to forced cutting, and the broken cutting piece 302 fragments will cause passive damage to the components in the machine body 1; this also helps to maintain the stability and integrity of the overall structure of the device, reduces the risk of the entire device failing due to local damage, reduces maintenance costs and downtime.

[0085] Further, through the design of the life test assembly 5, the service life of the cutting blade 302 can be effectively tested; specifically, through the pressure value feedback of the pressure sensor 506 on the S-shaped piece 505, the service life of the cutting blade 302 can be indirectly understood; the above-mentioned test / detection work can improve the cutting quality of the metal rod 4 cut by the cutting blade 302, and ensure the flatness of the cutting surface; that is, by monitoring the reaction force on the cutting blade 302 to test the service life of the cutting knife, the wear condition of the cutting blade 302 can be found in time; when the reaction force is too large, it indicates that the cutting blade 302 is seriously worn at this time, and the cutting blade 302 can be replaced or repaired in advance at this time, so that cutting with an excessively worn cutting blade 302 can be avoided, thereby ensuring the flatness of the cutting surface; the flat cutting surface can meet the requirements of high-quality products, reduce the process of repairing or reprocessing the cutting surface in the subsequent processing process; improve work efficiency and maintain stable cutting speed: the assembly can monitor the wear degree of the cutting blade 302, avoid excessive wear of the cutting blade 302, and thus maintain a relatively stable cutting speed; at the same time, such timely discovery of the wear condition of the cutting blade 302 can prevent the cutting blade 302 from bursting; the bursting of the cutting blade 302 will cause the fragments to splash everywhere, damaging the equipment and causing equipment failure and maintenance downtime; by using the assembly, equipment failure caused by problems with the cutting blade 302 can be reduced, equipment maintenance time can be shortened, and the effective operation time of the equipment can be improved, thereby improving overall work efficiency and effectively preventing fragments from splashing and injuring operators, ensuring the safety of operators;

[0086] The above working process is described with reference to Figure 1 , Figures 4 to 6 .

[0087] The working process of the waste dust treatment assembly 6 is as follows:

[0088] Further, during the cutting of the metal rod 4 by the cutting blade 302, the fan 605 in the waste dust treatment assembly 6 is in a starting state, since the bottom of the machine body 1 is provided with a cavity, the collection cover 601 is connected to the cavity formed in the bottom of the machine body 1, therefore, when the metal rod 4 is cut, the fan 605 will perform suction work on the debris and waste dust generated during the cutting of the metal rod 4 through the cavity in the bottom of the machine body 1 with the assistance of the waste dust treatment area on one side of the partition plate 101; with the intervention of suction, the debris and waste dust that should have stayed in the cutting area will be transferred to the waste dust treatment area on one side of the partition plate 101, and then part of the small-diameter debris and waste dust will be transferred out through the external discharge pipe 606 after being assisted by the filter plate 603 and the secondary filter cylinder 604, and the debris and waste dust with larger diameters will fall into the cavity formed in the bottom of the machine body 1, waiting to be transferred after the cutting work is completed;

[0089] Further, through the design of the waste dust treatment assembly 6, the debris and metal waste dust generated during the cutting of the metal rod 4 by the cutting piece 302 can be effectively collected and treated, the working environment can be improved, and the air quality can be improved. The assembly can collect debris and waste dust during the cutting process, effectively reduce the concentration of metal waste dust particles in the air, avoid workers inhaling a large amount of dust, reduce the irritation to the respiratory tract, reduce the occurrence of coughing and wheezing symptoms, and reduce the risk of respiratory diseases such as bronchitis and pneumoconiosis. Improve visibility and reduce equipment and work area pollution: By collecting waste dust, the visibility of the work area can be prevented from being reduced due to a large amount of waste dust, and workers can more clearly see the cutting position, which is conducive to observing and ensuring cutting progress and quality. Collecting waste dust in a timely manner can prevent it from falling on the surface of the equipment and the work area, prevent metal waste dust from accumulating and affecting the heat dissipation performance of the equipment, ensure the normal heat dissipation of the motor and other key components of the cutting machine 301, and prolong the service life of the equipment. At the same time, it reduces the burden of cleaning work and avoids the accumulation of dust affecting work efficiency and polluting other workpieces. Enhance work safety and reduce the risk of fire and explosion: The assembly collects waste dust to prevent metal waste dust from contacting the skin and eyes of workers, prevent skin allergies, swelling, and eye pain, inflammation, and vision damage problems. It can avoid too high concentration of metal dust in the air. In the case of sparks generated during cutting of the metal rod 4 causing an explosion, the assembly eliminates the hidden danger of dust explosion and protects personnel and equipment from serious damage caused by the explosion.

[0090] The above working process is described in detail in the following Figure 2 , Figure 4 , Figure 7 , Figure 8 .
