Description

Technical Field

[0001] The utility model relates to the technical field of roller hearth furnace equipment, in particular to an anti-collision tooling for a quenching zone of a roller hearth furnace. Background Art

[0002] The quenching of aluminum plates is carried out in a roller hearth furnace, and the main quenching zone and post-cooling section of the roller hearth furnace achieve quenching and cooling effects by spraying water through nozzles. Figure 1 As shown, in order to improve the quenching and cooling effects, a quenching zone top nozzle 1 is provided at the top of the roller table of the roller hearth furnace; a quenching zone bottom nozzle 2 is provided at the bottom of the roller table of the roller hearth furnace between two transition rollers 4; the plate 3 is on the transition roller 4 and moves forward as the transition roller 4 rolls.

[0003] During the quenching and cooling process, the aluminum plate will be affected by its own weight and temperature, and will show obvious downward deformation at both ends. The thinner the plate, the more sensitive it is to the water flow rate, and the greater the deformation. This will cause the aluminum plate to collide with the nozzle 2 at the bottom of the quenching zone during the forward process, causing material jamming and requiring manual cleaning. This not only affects production efficiency, but also causes damage to the nozzle 2 at the bottom of the quenching zone and the aluminum plate. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-collision tooling for the quenching zone of a roller hearth furnace, which effectively protects the nozzle at the bottom of the quenching zone by supporting and guiding the plate, while avoiding the plate from getting stuck and improving production efficiency.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an anti-collision tooling for the quenching zone of a roller hearth furnace, comprising a base frame and guide rods evenly fixed on the base frame and arranged in parallel; the height of the guide rods from the bottom of the base frame is higher than the height of the bottom nozzle of the quenching zone and the bottom of the roller, and is lower than the height of the top horizontal section of the transition roller and the bottom of the roller.

[0006] After adopting the above structure, by placing the base frame at the bottom of the roller table between two adjacent transition rollers, the height of the guide rod is higher than the height of the nozzle at the bottom of the quenching zone, thereby forming effective protection for the nozzle at the bottom of the quenching zone; and the guide rod connects the two adjacent transition rollers, thereby filling the distance between the two adjacent transition rollers. The guide rod effectively supports and guides the plate, preventing it from being stuck between the two adjacent transition rollers, avoiding plate jamming, and thus improving production efficiency.

[0007] In order to achieve lightweight and reduce the weight of the tooling, the chassis includes two relatively arranged door-type brackets. The tops of the two door-type brackets are fixedly connected by a connecting rod, and the connecting rod avoids the lower spray pipe; the guide rods are fixed on the connecting rods at intervals and avoid the bottom nozzle of the quenching zone.

[0008] In order to ensure balanced force and increase its service life, the connecting rod is located in the middle of the two door-shaped brackets.

[0009] In order to limit the door-type bracket, ensure its installation accuracy, and avoid hard collision with the transition roller caused by rocking back and forth, two lower spray pipes are provided, and the two legs of the door-type bracket respectively rest on the outer side walls of the two lower spray pipes.

[0010] In order to limit the position of the door-type bracket and ensure its position accuracy during the production process, a tightening bolt is screwed on the legs of the door-type bracket, and the inner end of the tightening bolt is tightened on the corresponding lower spray pipe.

[0011] In order to facilitate the screwing of the tightening bolt, a rotating head is fixed to the outer end of the tightening bolt, and an anti-slip thread is provided on the rotating head.

[0012] In order to ensure a firm connection between the door-shaped bracket and the bottom of the roller conveyor and avoid fluctuations due to vibration, magnets are provided at the bottom of the legs of the door-shaped bracket.

[0013] In order to better guide the plate and reduce the friction between the plate and the guide rod, downwardly bent arc heads are provided at both ends of the guide rod, and the arc heads are tangent to the transition rollers on the corresponding sides.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are:

[0015] The utility model discloses an anti-collision tooling for the quenching zone of a roller hearth furnace, which solves the technical problem in the prior art that during quenching and cooling, plates are deformed by being knocked down, causing collision with the bottom nozzle of the quenching zone during the forward movement, thereby causing material jamming. The utility model provides support and guidance for the plates, thereby effectively protecting the bottom nozzle of the quenching zone, avoiding plate jamming, and improving production efficiency.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] The orientations mentioned in this specification are based on the orientations of the anti-collision tooling for the quenching zone of a roller hearth furnace of the present invention during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0025] Example 1:

[0026] like Figure 2 and Figure 3 As shown, an anti-collision fixture for the quenching zone of a roller-hearth furnace includes a base frame 51 and guide rods 52 uniformly fixed to and arranged parallel to the base frame 51. The base frame 51 can be fixed to the roller bottom 41 between adjacent transition rollers 4. The length of the guide rods 52 is perpendicular to the axis of the transition roller 4. The two ends of the guide rods 52 are non-contact connected to the adjacent transition rollers 4, thereby filling the gap between the adjacent transition rollers 4.

[0027] The height of the guide rod 52 from the bottom of the base frame 51 is higher than the height of the nozzle 2 at the bottom of the quenching zone and the bottom 41 of the roller, and lower than the height of the top horizontal section of the transition roller 4 and the bottom 41 of the roller. Since the height of the guide rod 52 is higher than the height of the nozzle 2 at the bottom of the quenching zone, the nozzle 2 at the bottom of the quenching zone is effectively protected, preventing the plate 3 from hitting the nozzle 2 at the bottom of the quenching zone. However, the height of the guide rod 52 is lower than the height of the top horizontal section of the transition roller 4 and the bottom 41 of the roller, thus providing support and guidance for the plate 3 without hindering the normal conveyance of the plate 3.

[0028] like Figure 4 As shown, the base frame 51 includes two relatively arranged door-shaped brackets 511, and the tops of the two door-shaped brackets 511 are fixedly connected by a connecting rod 512. The connecting rod 512 avoids the lower spray pipe 21, and the guide rod 52 is fixed on the connecting rod 512 at intervals and avoids the bottom nozzle 2 of the quenching zone.

[0029] The connecting rod 512 is located in the middle of the two door-shaped brackets 511, thereby ensuring that the left and right forces are balanced. The lower spray pipe 21 is located at the bottom of the door-shaped bracket 511, realizing protection and avoidance of the lower spray pipe 21.

[0030] According to normal production requirements, two lower spray pipes 21 are provided between adjacent transition rollers 4 . The two lower spray pipes 21 are located on both sides of the connecting rod 512 , and the bottom nozzles 2 of the quenching zone are evenly arranged on the lower spray pipes 21 .

[0031] The two legs of the door-shaped bracket 511 respectively rest against the outer side walls of the two lower spray pipes 21 , and the positioning of the door-shaped bracket 511 is achieved through the two lower spray pipes 21 to prevent the door-shaped bracket 511 from shaking and causing the upper guide rod 52 to touch the transition roller 4 .

[0032] To further position the gate bracket 511, a through-hole is provided in the gate bracket 511. A threaded sleeve is fixed in the through-hole, and a tightening bolt 513 is screwed onto the sleeve. The inner end of the tightening bolt 513 tightens against its corresponding lower spray pipe 21. There are four tightening bolts 513, located at the four corners of the base frame 51. The outer end of the tightening bolt 513 is fixed with a rotating head with anti-slip threads to facilitate manual tightening.

[0033] The bottom of the legs of the door-shaped bracket 511 is provided with a magnet (not shown in the figure), and the magnet can be attracted to the bottom 41 of the roller.

[0034] like Figure 2 - Figure 5 As shown in the figure, the installation process of an anti-collision tooling for the quenching zone of a roller hearth furnace is as follows:

[0035] Place the door-shaped bracket 511 between two adjacent transition rollers 4. At this time, the two lower spray pipes 21 are respectively against the two sides of the bottom of the door-shaped bracket 511, thereby achieving its positioning; then tighten the tightening bolts 513 to tighten the door-shaped bracket 511 to the lower spray pipes 21; when the plate 3 is transported over, the guide rod 52 supports and guides the plate 3 to prevent the plate 3 from hitting the bottom nozzle 2 of the quenching zone, and the bottom nozzle 2 of the quenching zone sprays water from between the adjacent guide rods 52 to cool the plate 3.

[0036] Example 2:

[0037] like Figure 6As shown, although the guide rod 52 fills the gap between the two adjacent transition rollers 4, a small gap still exists between the guide rod 52 and the transition roller 4. Although this gap is not large enough to hold the sheet 3 in place, it still creates a certain amount of friction on the sheet 3. Therefore, this embodiment is a further improvement on the first embodiment. A downwardly bent arc-shaped head 521 is provided at both ends of the guide rod 52. The arc-shaped head 521 is tangent to the transition roller 4 on its corresponding side. When the sheet 3 comes over and hits the arc-shaped head 521, because the arc-shaped head 521 is a circular arc structure, it smoothly guides the sheet 3 and does not form a right-angled obstruction to the sheet 3, allowing the sheet 3 to fall smoothly onto the guide rod 52, thereby preventing the sheet 3 from getting stuck.

[0038] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
