Description

Technical Field

[0001] The utility model relates to the technical field of stamping die cleaning, and more specifically to a portable debris cleaning tool. Background Art

[0002] In the auto parts stamping workshop, the parts mainly go through the processes of blanking, drawing, trimming, punching, shaping and flanging. In the trimming and punching processes, metal debris is easily generated. These debris will adhere to the tool or the mold surface and affect the stamping of the parts. First, it may cause scratches, pits or other defects on the parts; second, it may cause increased mold wear in the subsequent stamping process, shortening the service life of the mold; third, it may enter the transmission system or other components of the equipment, causing unstable operation or failure of the equipment. Therefore, it is necessary to use cleaning tools to regularly remove the debris on the stamping die in time to avoid the impact of these debris on the quality of auto parts and molds.

[0003] The prior art discloses a debris cleaning device for cleaning debris generated by mold stamping. The debris cleaning device includes a debris channel tube, a vacuum suction device installed on the debris channel tube, and an air pipe for introducing a compressed air source. The air pipe is interconnected with the vacuum suction device and the debris channel tube, so that when the vacuum suction device generates negative pressure in the debris channel tube, the air at the inlet of the debris channel tube and the debris flow to the outlet of the debris channel tube together with the compressed air source in the air pipe.

[0004] However, some metal chips have too strong mutual adhesion to the mold and are difficult to be sucked by the chip channel tube. At the same time, some chips are hidden in corners or concave and convex places that are difficult to reach by the chip channel tube and cannot be sucked, resulting in poor cleaning of metal chips. Utility Model Content

[0005] In view of the problem that the above-mentioned prior art method of cleaning metal debris by only adsorbing the metal debris is not able to clean it thoroughly, the utility model provides a portable debris cleaning tool, which can improve the cleaning rate of metal debris and reduce the residual metal debris on the mold.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0007] A portable debris cleaning tool comprises a gun barrel provided with a first air port and a second air port, the second air port being connected to a first pipeline, the first pipeline being connected to a second pipeline, the first pipeline and the second pipeline being both communicated with an inner cavity of the gun barrel, a first valve, a suction device and a dust bag being sequentially provided on the first pipeline from one end close to the gun barrel to the other end thereof, the inner cavity of the dust bag being communicated with the inner cavity of the gun barrel via the first pipeline; the second pipeline being used for connecting to an external air source, the second pipeline being provided with a second valve.

[0008] In the above technical solution, the gun barrel can realize the functions of blowing and inhaling. When blowing is required, the first valve and the second valve are adjusted to disconnect the suction device from the gun barrel, and the external air source is connected to the gun barrel, and then the external air source passes through the second pipeline and the inner cavity of the gun barrel, and finally ejects from the first air port, thereby realizing the blowing function. When inhaling is required, the first valve and the second valve are adjusted to connect the suction device to the gun barrel, and the external air source is disconnected from the gun barrel, and then a negative pressure is formed inside the suction device to inhale air into the inner cavity of the gun barrel, thereby realizing the inhalation function. When it is necessary to clean metal debris, first blow air to the mold surface through the gun barrel to blow the debris on the mold surface, reduce the adhesion between the debris and the mold, and at the same time blow some debris in hard-to-reach corners to a wider area; then inhale air to the mold surface through the gun barrel to absorb metal debris, so that the metal debris passes through the inner cavity of the gun barrel and the second pipeline in turn, and finally enters the dust bag. Blowing metal debris and then sucking it up can effectively reduce the adhesion of metal debris, spread the distribution range of metal debris, avoid excessive debris accumulation, and make full use of the synergistic effect of blowing and sucking to improve the cleaning effect and ensure that the metal debris on the surface of the stamping die can be effectively cleaned.

[0009] Wherein, the suction device can be a vacuum pump or a pneumatic vacuum conveyor. Preferably, the suction device is a pneumatic vacuum conveyor. The pneumatic vacuum conveyor has a simple structure and is relatively lightweight. It only needs to provide an air intake source to the pneumatic vacuum conveyor to generate negative pressure inside the pneumatic vacuum conveyor. No power drive is required, which makes it convenient for staff to hold the tool and move around. Moreover, the pneumatic vacuum conveyor can convey powdered and granular solids and has a wide range of applications. Even if it is used to absorb metal debris, it is not easy to generate friction or vibration, which can ensure the stability and reliability of the suction process. Since the pneumatic vacuum conveyor is a prior art, its specific structure will not be described in detail.

[0010] Preferably, the second valve is a three-way valve, and one of the air outlet interfaces of the second valve is connected to the air source interface of the suction device. It is understandable that the three-way valve of the prior art has an air inlet interface and two air outlet interfaces, wherein the air inlet interface is used to connect to the external air source, and one of the air outlet interfaces is connected to the gun barrel, and the other air outlet interface is connected to the air source interface of the suction device. When the gun barrel needs to inhale air, the second valve is adjusted to connect the external air source to the suction device, the second pipeline is disconnected from the gun barrel, and the first valve is adjusted to connect the suction device to the gun barrel; then the airflow of the external air source enters the negative pressure cavity of the suction device through the second pipeline and the second valve, and then enters the dust bag, so that the negative pressure cavity of the suction device generates negative pressure, thereby generating suction force on the inner cavity of the gun barrel. When the gun barrel needs to be blown, the first valve is adjusted to disconnect the gun barrel from the suction device, and the second valve is adjusted to disconnect the external air source from the suction device, the external air source is connected to the inner cavity of the gun barrel, and the airflow of the external air source flows into the gun barrel through the second pipeline. That is to say, after the second valve is set as a three-way valve, only one external air source needs to be set to meet the needs of the gun barrel's air suction and air blowing functions at the same time, which is conducive to reducing the setting amount of the external air source.

[0011] Preferably, a conical nozzle is connected to the first air port, the inner cavity of the conical nozzle is connected to the first air port, and the caliber of one end of the nozzle away from the first air port is smaller than the caliber of the other end thereof. When the barrel is blown, the conical nozzle can concentrate the airflow inside the barrel and increase the airflow speed, thereby generating a greater wind force to blow the metal debris and improve the loosening rate of the metal debris.

[0012] Preferably, the dust bag is provided with a plurality of ventilation holes. When the gun barrel is inhaling air, the metal debris and the air flow are sucked into the dust bag together, and then the air flow is discharged from the dust bag through the ventilation holes, while the metal debris remains in the dust bag. The plurality of ventilation holes can be provided to timely discharge the excess gas in the dust bag, thereby avoiding the obstruction of the metal debris adsorption process caused by the excessive internal air pressure of the dust bag.

[0013] Preferably, the dust bag is provided with a discharge port, the inner cavity of the dust bag is connected to the outside of the dust bag through the discharge port, and the discharge port is provided with a sealing component for closing the discharge port. When the amount of metal debris in the dust bag reaches a certain amount, the sealing component can be adjusted to open the discharge port so that the metal debris can be discharged from the discharge port, which can facilitate the collection and subsequent treatment of the metal debris, and there is no need to remove the entire dust bag to pour out the metal debris, which is conducive to simplifying the cleaning of the metal debris.

[0014] The sealing assembly may be a sealing cover detachably connected to the dust bag or a zipper assembly connected to the dust bag. Preferably, the sealing assembly includes a zipper assembly connected to the dust bag. The structure of the zipper assembly is the same as that of the zipper assembly in the prior art, and both include two zipper tapes with sprockets and a zipper head for connecting the sprockets on the two zipper tapes. The sealing and unsealing of the discharge port is achieved by pulling the zipper head of the zipper assembly, which is relatively convenient and quick to operate.

[0015] Preferably, the discharge port is arranged on the side of the dust bag away from the gun barrel, that is, the bottom side of the dust bag. In the process of adsorbing metal debris, most of the metal debris will flow to the bottom side of the dust bag under the impetus of the airflow. The remaining metal debris can flow to the bottom side of the dust bag under its own gravity and finally be discharged through the discharge port. Therefore, setting the discharge port on the bottom side of the dust bag can make the discharge of metal debris smoother and more thorough, and it is not easy to accumulate in the dust bag.

[0016] Preferably, the gun barrel is made of stainless steel. The gun barrel made of stainless steel has good wear resistance and corrosion resistance, is not easily damaged even if it is rubbed by metal debris for a long time, and has a longer service life.

[0017] Preferably, the dust bag is made of polyester fiber material. The dust bag made of polyester fiber has good wear resistance and durability, and is not easy to wear or break under the friction of metal debris. At the same time, it has a certain air permeability, which can be understood as the dust bag has the above-mentioned air permeable hole structure. In the process of adsorbing metal debris, the air flow can be discharged through the air permeable holes on the dust bag. In addition, the polyester fiber bag is relatively light and easy to carry.

[0018] Beneficial effects of the utility model:

[0019] (1) The first pipeline and the second pipeline are arranged to suck air and blow air into the inner cavity of the barrel respectively, so that the barrel has the functions of blowing and sucking air. Using the barrel to blow metal debris and then sucking it can effectively reduce the adhesion of metal debris, spread the distribution range of metal debris, avoid excessive debris accumulation, and make full use of the synergistic effect of blowing and sucking air to improve the cleaning effect, ensuring that the metal debris on the surface of the stamping die can be effectively cleaned.

[0020] (2) The second valve on the second pipeline is a three-way valve. The external air source can directly enter the gun barrel through the second valve, and can also enter the pneumatic vacuum conveyor through the second valve. Only one external air source is needed to simultaneously meet the needs of the gun barrel's suction and blowing functions.

[0021] (3) The dust bag is provided with a plurality of ventilation holes, through which the gas in the dust bag can be discharged, while the metal debris is retained in the dust bag; the dust bag is also provided with a discharge port and a zipper assembly, through which the metal debris in the dust bag can be discharged, which can facilitate the collection and subsequent treatment of the metal debris and simplify the cleaning work of the staff.

[0022] (4) The tool has a simple and lightweight structure, making it convenient for workers to carry it for large-scale cleaning work. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0032] Example 1

[0033] Combination Figures 1 to 3 A portable debris cleaning tool is shown, which includes a gun barrel 1 provided with a first air port 101 and a second air port 102, the second air port 102 is connected to a first pipeline 2, the first pipeline 2 is connected to a second pipeline 3, the first pipeline 2 and the second pipeline 3 are both connected to the inner cavity of the gun barrel 1, and the first pipeline 2 is provided with a first valve 4, a suction device 5 and a dust bag 6 in sequence from one end close to the gun barrel 1 to the other end thereof, the inner cavity of the dust bag 6 is connected to the inner cavity of the gun barrel 1 through the first pipeline 2; the second pipeline 3 is used to connect to an external air source, and the second pipeline 3 is provided with a second valve 7.

[0034] Specifically, the suction device 5 is a pneumatic vacuum conveyor. The pneumatic vacuum conveyor has a simple structure and is relatively light. It only needs to provide an air intake source to the pneumatic vacuum conveyor to generate negative pressure inside the pneumatic vacuum conveyor. No power drive is required, which makes it convenient for workers to hold the tool and move around. In addition, the pneumatic vacuum conveyor can convey powdered and granular solids and has a wide range of applications. Even if it is used to absorb metal debris, it is not easy to generate friction or vibration, which can ensure the stability and reliability of the suction process. Since the pneumatic vacuum conveyor is a prior art, its specific structure will not be described in detail.

[0035] Specifically, the second valve 7 is a three-way valve, and one of the air outlet interfaces of the second valve 7 is connected to the air source interface of the suction device 5. It can be understood that the three-way valve in the prior art has one air inlet interface and two air outlet interfaces, wherein the air inlet interface is used to connect to an external air source, and one of the air outlet interfaces is connected to the gun barrel 1, and the other air outlet interface is connected to the air source interface of the suction device 5. After the second valve 7 is set as a three-way valve, only one external air source needs to be set to meet the needs of the suction and blowing functions of the gun barrel 1 at the same time, which is conducive to reducing the setting amount of the external air source.

[0036] Specifically, the gun barrel 1 is made of stainless steel material. The gun barrel 1 made of stainless steel material has good wear resistance and corrosion resistance, is not easily damaged even if it is rubbed by metal debris for a long time, and has a longer service life.

[0037] The working principle or workflow of this embodiment is as follows: Figure 2 As shown in the figure, the arrow in the figure indicates the direction of air flow. When the gun barrel 1 needs to be blown, the first valve 4 is adjusted to disconnect the gun barrel 1 from the suction device 5, and the second valve 7 is adjusted to disconnect the external air source from the suction device 5, so that the external air source is connected to the inner cavity of the gun barrel 1, so that the airflow of the external air source flows into the gun barrel 1 through the second pipeline 3. Figure 3 As shown, the arrow in the figure indicates the direction of air flow. When the barrel 1 needs to inhale, the second valve 7 is adjusted to connect the external air source with the suction device 5, the second pipeline 3 is disconnected from the barrel 1, and the first valve 4 is adjusted to connect the suction device 5 with the barrel 1; then the airflow of the external air source enters the negative pressure cavity of the suction device 5 through the second pipeline 3 and the second valve 7, and then enters the dust bag 6, so that the negative pressure cavity of the suction device 5 generates negative pressure, thereby generating suction force on the inner cavity of the barrel 1. When it is necessary to clean metal debris, first blow air to the mold surface through the barrel 1 to blow away the debris on the mold surface, reduce the adhesion between the debris and the mold, and at the same time blow away some debris in corners that are difficult to reach to a wider area; then inhale air to the mold surface through the barrel 1 to absorb the metal debris, so that the metal debris passes through the inner cavity of the barrel 1 and the second pipeline 3 in turn, and finally enters the dust bag 6.

[0038] Beneficial effects of this embodiment:

[0039] (1) The first pipeline and the second pipeline are arranged to suck air and blow air into the inner cavity of the barrel respectively, so that the barrel has the functions of blowing and sucking air. Using the barrel to blow metal debris and then sucking it can effectively reduce the adhesion of metal debris, spread the distribution range of metal debris, avoid excessive debris accumulation, and make full use of the synergistic effect of blowing and sucking air to improve the cleaning effect, ensuring that the metal debris on the surface of the stamping die can be effectively cleaned.

[0040] (2) The second valve on the second pipeline is a three-way valve. The external air source can directly enter the gun barrel through the second valve, and can also enter the pneumatic vacuum conveyor through the second valve. Only one external air source is needed to simultaneously meet the needs of the gun barrel's suction and blowing functions.

[0041] Example 2

[0042] This embodiment is based on the embodiment 1. Figure 1As shown, the first air port 101 is connected to a conical nozzle 8, the inner cavity of the conical nozzle 8 is in communication with the first air port 101, and the diameter of one end of the nozzle away from the first air port 101 is smaller than the diameter of the other end. When the barrel 1 is blown, the conical nozzle 8 can concentrate the airflow inside the barrel 1 and increase the airflow speed, thereby generating a greater wind force to blow the metal debris and improve the loosening rate of the metal debris.

[0043] Other features, working principles and beneficial effects of this embodiment are consistent with those of Embodiment 1.

[0044] Example 3

[0045] This embodiment is based on the embodiment 2, combined with Figure 1 , Figure 4 and Figure 5 As shown, the dust bag 6 is provided with a plurality of ventilation holes (not shown in the figure). During the process of the gun barrel 1 sucking air, the metal debris and the air flow are sucked into the dust bag 6 together, and then the air flow is discharged from the dust bag 6 through the ventilation holes, while the metal debris remains in the dust bag 6. The plurality of ventilation holes can be provided to timely discharge the excess gas in the dust bag 6, and avoid the obstruction of the metal debris adsorption process caused by the excessive internal air pressure of the dust bag 6.

[0046] Furthermore, the dust bag 6 is provided with a discharge port 601, through which the inner cavity of the dust bag 6 is connected to the outside of the dust bag 6, and the discharge port 601 is provided with a sealing component for closing the discharge port 601. When the amount of metal debris in the dust bag 6 reaches a certain amount, the sealing component can be adjusted to open the discharge port 601, so that the metal debris is discharged from the discharge port 601, which can facilitate the collection and subsequent treatment of the metal debris, and there is no need to remove the entire dust bag 6 to pour out the metal debris.

[0047] Specifically, the sealing assembly includes a zipper assembly 602 connected to the dust bag 6. The structure of the zipper assembly 602 is the same as that of the zipper assembly 602 in the prior art, and both include two zipper tapes with sprockets and a zipper head for connecting the sprockets on the two zipper tapes. The sealing and unsealing of the discharge port 601 is achieved by pulling the zipper head of the zipper assembly 602, which is relatively convenient and quick to operate.

[0048] Specifically, the discharge port 601 is arranged on the side of the dust bag 6 away from the gun barrel 1, that is, the bottom side of the dust bag 6. In the process of adsorbing metal debris, most of the metal debris will flow to the bottom side of the dust bag 6 under the impetus of the airflow. The remaining metal debris can flow to the bottom side of the dust bag 6 under its own gravity and finally be discharged through the discharge port 601. Therefore, the discharge port 601 is arranged on the bottom side of the dust bag 6 so that the discharge of metal debris can be smoother and more thorough, and it is not easy to accumulate in the dust bag 6.

[0049] Specifically, the dust bag 6 is made of polyester fiber material. The dust bag 6 made of polyester fiber has good wear resistance and durability, and is not easy to wear or break under the friction of metal debris. At the same time, it has a certain air permeability. It can be understood that the dust bag 6 has the above-mentioned air permeable hole structure. In the process of adsorbing metal debris, the air flow can be discharged through the air permeable holes on the dust bag. In addition, the polyester fiber bag is relatively light and easy to carry.

[0050] The other features, working principles and beneficial effects of this embodiment are consistent with those of Embodiment 2.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description, and it is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
