A blackening device for producing high corrosion-resistant bolt fasteners

Abstract

The invention discloses a blackening device for producing high-corrosion-resistant bolt fasteners, comprising a blackening barrel. A flipping mechanism is arranged on the top of the blackening barrel, and relates to the technical field of blackening. By arranging the flipping mechanism, the mutual magnetic attraction is separated. Since the weights of the semicircular plates on both sides of the rotating rod are different, the semicircular plates drive the rotating rod to flip quickly, so that all the bolts are dumped into the blackening liquid in the blackening barrel to complete the blackening work. When the bolts are dumped, they are evenly screened by a plurality of screening bars to make them fall, so as to ensure that they can evenly enter the blackening barrel, avoid concentrated accumulation and mutual squeezing in the blackening barrel, and affect the blackening effect. After all the bolts enter the blackening barrel, the semicircular plates will continue to rotate with inertia until the magnetic blocks on the outer walls of the semicircular plates contact the magnetic grooves in the blackening barrel again, and the magnetic attraction stops, so as to automatically close the blackening barrel and reduce the problem of oxidation between the blackening liquid and the air.

Description

Technical Field

[0001] The invention relates to the technical field of blackening, in particular to a blackening device for producing high-corrosion-resistant bolt fasteners. Background Art

[0002] New energy vehicles are vehicles that use unconventional automotive fuels as their power source. Bolts are used extensively in their manufacturing. Bolts are mechanical parts, cylindrical threaded fasteners that fit into nuts. These fasteners consist of a head and a screw (a cylindrical body with external threads). They are used in conjunction with nuts to fasten two parts with through-holes.

[0003] The blackening device for producing bolt fasteners for energy vehicles, described in patent application publication number CN214458321U, is specifically a device for producing bolt fasteners for new energy vehicles. The device comprises a mounting housing; two sliders symmetrically slidably mounted within the mounting housing; two support rods symmetrically fixedly mounted on the two sliders; a supporting housing slidably mounted on the two support rods; and a threaded rod rotatably mounted on the inner wall of the mounting housing. The threaded rod is threadedly connected to one of the sliders, and the top end of the threaded rod extends sealedly outside the mounting housing.

[0004] When the bolts are blackened, a large number of bolts need to be poured into the blackening liquid for blackening. However, when the bolts are put into the barrel of blackening liquid in batches, the bolts pile up on each other and partially adhere to each other, resulting in the bolts not being able to fully contact the blackening liquid when entering the blackening liquid, which easily leads to the problem that some parts cannot be blackened. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a blackening device for producing high-corrosion-resistant bolt fasteners, which achieves the purpose of solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A blackening device for producing high-corrosion-resistant bolt fasteners, comprising a blackening barrel, the top of which is provided with a turning mechanism;

[0007] The turning mechanism comprises:

[0008] The circular cover is a circular ring structure. The inner wall of the circular cover is rotatably connected to a rotating rod. The outer wall of the rotating rod is fixedly connected to a semicircular plate. The inner wall of the semicircular plate is provided with a holding groove. The circular cover is used to connect and close the channel inside the blackening barrel.

[0009] The magnetic block is an L-shaped block structure, the outer wall of the magnetic block is fixedly connected to the outer wall of the semicircular plate, the inner wall of the circular cover is provided with a magnetic groove, and the surface of the holding groove is provided with a dust storage groove, and the magnetic block is used to play the role of magnetic attraction with the magnetic groove.

[0010] Preferably, the outer wall of the semicircular plate is fixedly connected with a screening bar, the outer wall of the screening bar is fixedly connected with a semicircular bar, and the outer wall of the semicircular plate is provided with a toggle mechanism.

[0011] Preferably, the toggle mechanism includes a sliding groove A, which is provided on the outer wall of the semicircular plate. The sliding groove A is in a semicircular arc shape, and the inner wall of the sliding groove A is slidably connected to a slider A.

[0012] Preferably, the outer wall of the slider A is rotatably connected to a rotating ball A, the outer wall of the rotating ball A is fixedly connected to a telescopic rod, and the outer wall of the telescopic rod is rotatably connected to a rotating ball B.

[0013] Preferably, the outer wall of the rotating ball B is fixedly connected to a connecting rod, and the outer wall of the connecting rod is fixedly connected to a slider B.

[0014] Preferably, a sliding groove B is provided on the inner wall of the semicircular bar, and the inner wall of the sliding groove B is slidably connected to the outer wall of the slider B.

[0015] Preferably, a toggle bar is fixedly connected to the outer wall of the telescopic rod, and the toggle bar is made of rubber and is elastic.

[0016] Preferably, a stopper is fixedly connected to the inner wall of the sliding groove B, the magnetic block and the magnetic groove are magnetic, and the magnetism of the magnetic block and the magnetic groove on the opposite side is that opposite poles attract each other.

[0017] The present invention provides a blackening device for producing high-corrosion-resistant bolt fasteners. It has the following beneficial effects:

[0018] 1. The present invention sets a flipping mechanism to disengage the mutual magnetic attraction. Since the weights of the semicircular plates on both sides of the rotating rod are different, the semicircular plates drive the rotating rod to flip quickly, thereby dumping all the bolts into the blackening liquid in the blackening barrel to complete the blackening work. When the bolts are dumped, they are evenly screened by a large number of screening bars to make them fall, ensuring that they can enter the blackening barrel evenly, avoiding concentrated accumulation and mutual squeezing in the blackening barrel, which affects the blackening effect. After all the bolts enter the blackening barrel, the semicircular plates will continue to rotate with inertia until the magnetic block on the outer wall of the semicircular plates contacts the magnetic groove in the blackening barrel again, and the magnetic attraction stops, thereby automatically closing the blackening barrel and reducing the problem of oxidation between the blackening liquid and the air.

[0019] 2. The present invention sets a flip mechanism. As a large number of bolts drive the semicircular plate to rotate and descend in the containing groove, some of the bolts that can pass through the screening bars will begin to swing back and forth under the rotating rod due to the gravity of the bolts covered by the screening bars. The swinging will further shake the bolts and make them fall between the screening bars, thereby ensuring the stability of screening. After falling, they rotate with the inertia of the swing, maintaining the magnetic attraction between the magnetic block and the magnetic groove.

[0020] 3. The present invention is provided with a toggle mechanism. When the semicircular plate flips, the slider A in the sliding groove A opened in the holding groove will start to slide down on the inner wall of the sliding groove A due to gravity, that is, it will slide in the direction of the magnetic block, thereby driving the telescopic scraper to slide and scrape in the holding groove, and the other end of the telescopic scraper is hinged and limited to the inner wall of the holding groove, so that the telescopic scraper is driven by the slider A to move and rotate, and its own telescopic sliding rotates and toggles the inner wall of the holding groove to scrape a large amount of residue placed by the bolt into the dust storage tank, and static electricity is generated by the friction between the telescopic scraper and the holding groove, which keeps the residue on the bolt always adsorbed on the surface of the holding groove and difficult to fall into the blackening barrel easily, thereby ensuring the cleanliness of the inside of the blackening barrel.

[0021] 4. The present invention sets a toggle mechanism, which drives the rotating ball B and the telescopic rod to move through the connecting rod. The telescopic rod performs a hinged movement between the rotating ball B and the connecting rod through the rotating ball B and the rotating ball A, thereby completing the stretching and angle change of the telescopic rod. When the telescopic rod changes its angle and stretches itself, the bolts scattered between the receiving groove and the screening bar are toggled, so that the bolts are fully peeled off through the screening bar as the semicircular plate swings, thereby screening more evenly and avoiding the problem of mutual accumulation between the screening bar and the receiving groove, which causes the friction to squeeze each other and prevent them from falling. In addition, the toggle bar on the outer wall of the telescopic rod continuously toggles the bolts stuck on the surface of the screening bar. Because the toggle bar is made of elastic material, the bolts will not be squeezed when they cannot be toggled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION Example 1:

[0036] See also Figure 1-4 The present invention provides a technical solution: a blackening device for producing high corrosion-resistant bolt fasteners, comprising a blackening barrel 2, a turning mechanism 3 is provided on the top of the blackening barrel 2;

[0037] The turning mechanism 3 includes:

[0038] The circular cover 301 is a circular ring structure. The inner wall of the circular cover 301 is rotatably connected to the rotating rod 302. The outer wall of the rotating rod 302 is fixedly connected to the semicircular plate 303. The inner wall of the semicircular plate 303 is provided with a holding groove 306. The circular cover 301 is used to connect and close the channel inside the blackening barrel 2.

[0039] The magnetic block 308 is an L-shaped block structure. The outer wall of the magnetic block 308 is fixedly connected to the outer wall of the semicircular plate 303. The inner wall of the circular cover 301 is provided with a magnetic groove 309. The surface of the holding groove 306 is provided with a dust storage groove 307. The magnetic block 308 is used to play a role of magnetic attraction with the magnetic groove 309.

[0040] Install the circular cover 301 on the blackening barrel 2, and put the bolts that need to be blackened into the holding groove 306 on the blackening barrel 2. When a certain number of bolts are placed, their weight is greater than the magnetic attraction between the magnetic block 308 on the outer wall of the semicircular plate 303 and the magnetic groove 309, so that the mutual magnetic attraction is separated. Since the weights of the semicircular plates 303 on both sides of the rotating rod 302 are different, the semicircular plates 303 drive the rotating rod 302 to flip quickly, thereby dumping all the bolts into the blackening liquid in the blackening barrel 2, completing the blackening work, and When the bolts are dumped, they will be evenly screened by the numerous screening bars 304 so that they fall, ensuring that they can evenly enter the blackening barrel 2, avoiding concentrated accumulation and mutual squeezing in the blackening barrel 2, which will affect the blackening effect. After all the bolts have entered the blackening barrel 2, the semicircular plate 303 will continue to rotate with inertia until the magnetic block 308 on the outer wall of the semicircular plate 303 contacts the magnetic groove 309 in the blackening barrel 2 again, and the magnetic attraction stops, thereby automatically closing the blackening barrel 2 and reducing the problem of oxidation between the blackening liquid and the air. Example 2:

[0041] See also Figure 1-8 , based on the first embodiment, the present invention provides a technical solution: the outer wall of the semicircular plate 303 is fixedly connected with a screening bar 304, the outer wall of the screening bar 304 is fixedly connected with a semicircular bar 305, and the outer wall of the semicircular plate 303 is provided with a toggle mechanism 4;

[0042] As a large number of bolts drive the semicircular plate 303 to rotate and descend in the holding groove 306, some of the bolts that can pass through the screening strips 304 will begin to swing back and forth under the rotating rod 302 due to the gravity of the bolts covered by the screening strips 304. The swinging further causes the bolts to swing through the screening strips 304 and fall, ensuring the stability of the screening. After falling, they rotate with the inertia of the swinging, maintaining the magnetic attraction between the magnetic block 308 and the magnetic groove 309. Example 3:

[0043] See also Figure 1-13 Based on the first and second embodiments, the present invention provides a technical solution: the toggle mechanism 4 includes a sliding groove A401, the sliding groove A401 is opened on the outer wall of the semicircular plate 303, the sliding groove A401 is a semicircular arc, and the inner wall of the sliding groove A401 is slidably connected to the slider A402.

[0044] The outer wall of the slider A402 is rotatably connected to a rotating ball A409, the outer wall of the rotating ball A409 is fixedly connected to the telescopic rod 404, and the outer wall of the telescopic rod 404 is rotatably connected to a rotating ball B410.

[0045] The outer wall of the rotating ball B410 is fixedly connected to a connecting rod 405 , and the outer wall of the connecting rod 405 is fixedly connected to a slider B406 .

[0046] A sliding groove B407 is formed on the inner wall of the semicircular bar 305 , and the inner wall of the sliding groove B407 is slidably connected to the outer wall of the slider B406 .

[0047] The outer wall of the telescopic rod 404 is fixedly connected to a toggle bar 408 , which is made of rubber and is elastic.

[0048] A stopper 411 is fixedly connected to the inner wall of the sliding groove B407. The magnetic block 308 and the magnetic groove 309 are magnetic. The magnetism of the magnetic block 308 and the magnetic groove 309 on the opposite side is that opposite poles attract each other.

[0049] At the same time, when the semicircular plate 303 flips over, the slider A402 in the sliding groove A401 opened in the holding groove 306 will start to slide down on the inner wall of the sliding groove A401 under the force of gravity, that is, slide in the direction of the magnetic block 308, thereby driving the telescopic scraper 403 to slide and scrape in the holding groove 306, and the other end of the telescopic scraper 403 is hinged and limited to the inner wall of the holding groove 306, so that the telescopic scraper 403 is driven by the slider A402 to move and rotate, and its own telescopic sliding rotates and scrapes the inner wall of the holding groove 306, scraping a large amount of residue placed by the bolt into the dust storage tank 307, and through the friction between the telescopic scraper 403 and the holding groove 306, static electricity is generated, which keeps the residue on the bolt always adsorbed on the surface of the holding groove 306, and it is difficult to fall into the blackening barrel 2 easily, thereby ensuring the cleanliness of the inside of the blackening barrel 2;

[0050] At the same time, after the semicircular plate 303 flips down, the slider B406 in the sliding groove B407 will also fall due to gravity, and slide in the sliding groove B407 to approach the position of the stopper 411. When the slider B406 slides, it will drive the rotating ball B410 and the telescopic rod 404 to move through the connecting rod 405. The telescopic rod 404 performs a hinge movement between the rotating ball B410 and the connecting rod 405 through the rotating ball B410 and the rotating ball A409, thereby completing the stretching and angle change of the telescopic rod 404, so that when the telescopic rod 404 changes its angle and stretches itself , it will move the bolts scattered between the holding groove 306 and the screening bar 304, so that the bolts will be fully peeled off through the screening bar 304 as the semicircular plate 303 swings, thereby screening more evenly, avoiding accumulation between the screening bar 304 and the holding groove 306, which will cause the problem of being squeezed and stuck by friction and unable to fall, and the moving bar 408 on the outer wall of the telescopic rod 404 continuously moves the bolts stuck on the surface of the screening bar 304. Because the moving bar 408 is made of elastic material, it will not be squeezed when the bolts cannot be moved.

[0051] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
