Technical Field

[0001] The invention belongs to the field of energetic material machining, in particular to a chip removal and recovery device for energetic material machining. Background Art

[0002] In the process of processing energetic materials, various chips are usually generated. Chips are debris, chips and irregular shaped chips generated during the cutting of energetic materials. The chips from energetic material processing need to be recycled in the later stage to reduce the waste of resources. The chips will be splashed around by the high-speed rotating blades during processing, so after the processing is completed, the chips in the workplace need to be manually cleaned and collected. At the same time, a large amount of splashing chips and dust will affect the processing environment, which is not conducive to the health of workers. And because of the particularity of energetic materials, the splashing chips and dust will cause safety risks.

[0003] The chip recovery device in the existing processing technology cannot be applied to the chip recovery of energetic material processing, because the existing collection device cannot recover the splashed chips, and the chips in the processing area cannot be cleaned up in time. The splashing will lead to the waste of chips and cause safety hazards, and will also cause serious static electricity accumulation of chips, which is easy to cause fire.

[0004] Therefore, in view of the current situation, it is necessary to design a chip recovery device for energetic material processing. Summary of the invention

[0005] In view of the above problems, in order to ensure the rapid recovery of energetic material processing chips, a chip removal and recovery device for energetic material processing is provided, which can realize the recovery of cuttings while energetic material processing, prevent chips from splashing, and quickly remove chips, thereby improving recovery efficiency. At the same time, in order to improve the safety of recycling, the chips and dust of energetic materials need to be treated for static electricity to minimize the possibility of ignition of energetic materials. At the same time, this chip removal device can also provide auxiliary support for processing, increase the rigidity of the processing part structure, and improve the reliability and stability of energetic material processing.

[0006] The technical solution for achieving the purpose of the present invention is: a chip removal and recovery device for energetic material processing, the chip removal and recovery device comprising a sealed shell assembly and an air blowing assembly; the sealed shell assembly is arranged on the outside of the tool handle and the energetic material, and is used for protecting the flying chips of the energetic material and recovering the energetic material during the energetic material recovery processing; the air blowing assembly connects the inert gas and the internal space of the sealed shell assembly, and the air blowing assembly is used to clean the chips that have not fallen off the chip guide groove and eliminate the static electricity on the chips.

[0007] Compared with the prior art, the present invention has the following significant advantages: the chip removal and recovery device for energetic materials of the present invention has a good protective wrapping structure, so that the debris in the energetic material processing process will not randomly splash and affect the safety of the processing site. At the same time, the protective wrapping structure can collect the debris in a centralized manner, thereby effectively avoiding the splashing debris and dust from affecting the processing environment. In the chip removal process, the static electricity value of the debris can be reduced by inert gas ion wind, thereby reducing the safety risks caused by the particularity of energetic materials. The chip removal and recovery device for energetic materials of the present invention is also provided with a buffer support ring, which not only buffers the debris, but also has an auxiliary support function, thereby improving the stability of the processing. In addition, the chip removal and recovery device of the present invention has a simple structural design, is convenient and quick to use and operate, and is stable and reliable in processing, protection and chip collection. Its performance can meet the use requirements of energetic material processing. BRIEF DESCRIPTION OF THE DRAWINGS

After the left sealing plate 16 and the right sealing plate 17 are installed and aligned, the left sealing plate 16 and the right sealing plate 17 are respectively locked and fixed on the upper sealing cover plate 2 and the lower chip removal base 3 by the butterfly locking screw 15. A semicircular hole is opened in the middle of the left sealing plate 16, and the size of the semicircular hole is designed according to the outer diameter of the transmission component 6. A sealing flexible rubber sheet is pasted on the side of the semicircular hole. The design principle of the semicircular hole is based on the close fit between the sealing rubber sheet and the outer diameter of the transmission component 6. The design principle of the right sealing plate 17 is the same as that of the left sealing plate 16. A flexible rubber pad is installed on the plane where the right sealing plate 17 contacts the left sealing plate 16 to ensure sealing.

[0021] Preferably, a flexible pad is fixedly mounted on the upper sealing cover plate 2 between the mating planes where the upper sealing cover plate 2 and the lower chip removal base 3 contact, so as to ensure the sealing performance after the cover is closed.

[0023] The chip removal opening of the lower chip removal base 3 passes through the avoidance hole of the mounting substrate 1; the chip guide opening 18 is fixedly installed on the opposite side of the chip guide opening avoidance hole opened on the mounting substrate 1; waist grooves are provided on both sides of the sliding chip guide opening 19, and the sliding chip guide opening 19 can be moved up and down by limiting the locking and fixing columns fixed on the chip guide opening 18; when the sliding chip guide opening 19 needs to be fixed, it is only necessary to tighten the screws at the locking and fixing columns to fix the sliding chip guide opening 19 by static friction; the lower end of the sliding chip guide opening 19 can completely cover the collection box 20, and a flexible pad is installed on the surface where the sliding chip guide opening 19 contacts the collection box 20, which can ensure that the sliding chip guide opening 19 is in close contact with the collection box 20 to ensure sealing.

[0024] A flexible rubber pad is provided between the contact surface of the chip guide opening 18 and the mounting substrate 1 to ensure that the chip guide opening 18 and the mounting substrate 1 are closely fitted.

[0025] The upper end of the chip guide opening 18 is designed to be conical, so that the chips can fall in a concentrated manner, and the lower end is designed to be straight, so that it can be matched and slidably connected with the sliding chip guide opening 19 .

[0026] Waist-shaped grooves are provided on both sides of the sliding chip guide port 19, and the sliding chip guide port 19 can be moved up and down by limiting the locking and fixing columns fixed on the chip guide port 18; when the sliding chip guide port 19 needs to be fixed, it is only necessary to tighten the screws at the locking and fixing columns to fix the sliding chip guide port 19 by static friction.

[0027] A clearance fit is adopted between the chip guide opening 18 and the sliding chip guide opening 19. The tolerance of the clearance fit is selected so that the sliding chip guide opening can slide smoothly on the chip guide opening 18 smoothly.

[0028] The sliding chip guide opening 19 has a flange, and when in contact with the material collecting box 20 , the flange can effectively prevent the splashing of the chips and has a certain limiting effect on the material collecting box 20 .

[0029] The air blowing assembly is used to clean the unfallen chips on the chip guide groove and eliminate the static electricity on the chips. The air blowing assembly includes: an air blowing fixing plate 5, a threaded pipe, and a fan-shaped nozzle 21;

[0030] A blowing fixed plate 5 is fixedly installed on the top of the upper sealing cover plate 2. The blowing fixed plate 5 is respectively provided with threaded pipes on the top and bottom. The upper part of the threaded pipe is connected to an external inert gas supply device. A universal bamboo fan-shaped nozzle 21 is fixedly installed on the bottom of the threaded pipe.

[0031] The chip removal and recovery device for energetic material processing further comprises a buffer support ring 9 and a variable diameter reverse spiral chip guide groove 12 .

[0032] A linear bearing fixing seat 8 is fixedly installed on the other side of the chip guide avoidance hole opened in the middle of the mounting base 1 (the side opposite to the side fixing seat 4), and the transmission component 6 is circumferentially rotated with the linear bearing fixing seat 8 through a linear bearing 7. The outer circle of the transmission component 6 passes through the left sealing plate 16 and the right sealing plate 17, and fits tightly with the flexible rubber plates on the left and right sealing plates.

[0033] As an embodiment of the present invention, a buffer support ring 9 is installed at the radial end of the transmission component 6 to alleviate the impact of debris of the energetic material on the left sealing plate 16 and the right sealing plate 17 during processing. At the same time, during the processing, the buffer support ring 9 enters the interior of the metal shell of the energetic material together with the tool handle, thereby supporting the stability of the tool handle and further supporting the stability of the processing tool.

[0034] Specifically, the inner diameter of the buffer support ring 9 is clearance-matched with the transmission component 6, and the clearance-matching tolerance is based on the smooth disassembly and assembly of the buffer support ring 9; it is fixed to the transmission component 6 through the threaded holes on the buffer support ring 9.

The outer diameter of the buffer support ring 9 is smaller than the inner diameter of the metal shell of the energetic material to be processed. The outer diameter design criteria of the buffer support ring 9 are formulated according to the precision requirements of the energetic material processing. The buffer support ring 9 needs to have a certain strength and rigidity, and needs to prevent static electricity accumulation, so the buffer support ring 9 is made of anti-static ceramic material. The outer circumference of the buffer support ring 9 is designed with rounded corners to minimize sharp friction with the energetic material.

[0035] As an embodiment of the present invention, a tool handle 10 is installed at the shaft end of the transmission component 6, and mounting locking holes are provided at symmetrical positions on both sides of the tool handle 10. The tool handle 10 is locked and fixed to the transmission component 6 through the shoulder positioning locking screws 11. A variable diameter reverse spiral chip guide groove 12 is installed on the tool handle 10, and the spiral direction of the chip guide groove is opposite to the processing direction, which can realize the function of simultaneous processing and chip removal. The design criteria of the variable diameter reverse spiral chip guide groove 12 are determined according to the diameter of the energetic material to be processed and the processing feed rate, to ensure that the chips are smoothly discharged in the chip guide groove.

[0036] The working process of the chip recovery device for energetic material processing is as follows: the energetic recovery material is installed on the side fixing seat 4, the tool is installed at the end of the tool handle 10, and the tool processes the energetic material; during the chip removal process, the air inlet joint installed at the upper pipe thread of the air blowing fixing plate 5 is connected to the outlet of the inert gas, and an ion wind for eliminating static electricity is added in the middle, which can blow off the chips on the variable diameter reverse spiral chip guide groove 12 on the one hand, and neutralize the static electricity accumulation of the chips due to collision and friction and other factors through the blown-in ion wind, thereby ensuring the safety of the timely chip recovery process. Simultaneously, an explosion-proof static electricity detection sensor is installed on the lower chip removal base 3, which can monitor the static electricity accumulation in the chip removal process in real time. When the static electricity accumulation reaches the set threshold, an alarm is issued and all processing actions are stopped.

[0037] The present invention provides a timely chip removal and recovery device with auxiliary support for energetic material processing, which has a good protective wrapping structure, so that the debris in the energetic material processing process will not splash randomly and affect the safety of the processing site. At the same time, the protective wrapping structure can collect the debris in a centralized manner, thereby effectively avoiding the splashing debris and dust from affecting the processing environment. During the chip removal process, the static electricity value of the debris can be reduced by inert gas containing ions, thereby reducing the safety risks caused by the particularity of energetic materials. The auxiliary support function of this device improves the stability of processing. In addition, the timely chip removal and recovery device has a simple structural design, is convenient and easy to use and operate, and improves the safety and reliability of processing, protection, and chip collection and recovery.
