Description

Technical Field

[0001] This invention relates to the field of hot bending furnace technology, and in particular to a glass hot bending furnace for the production of rearview mirrors. Background Technology

[0002] Rearview mirrors are a key safety component of vehicles, used by drivers to obtain rear, side and downward visibility, and assist in lane changing, overtaking, reversing and other operations. Regulations in various countries mandate their installation and require them to be adjustable. During the production of rearview mirrors, the glass needs to be shaped into the required form using a hot bending furnace.

[0003] A hot bending furnace is a specialized high-temperature equipment used to heat flat glass to its softening point, bend and shape it using molds and gravity / pressure, and then anneal it to relieve stress. It is widely used in the production of curved glass for construction, automobiles, and home furnishings.

[0004] In use, most of the molds used in existing hot bending furnaces are concave molds. When the glass softens and sinks downwards, it blocks the gas under the concave mold. At this time, it is difficult for the gas under the glass to be released, which causes defects in the finished product when the glass is successfully shaped. Furthermore, the positioning and locking of the glass when it is placed on the mold is very cumbersome, and the clamps squeeze the glass when holding it, which can cause the glass to deform.

The outer shell 1 below the switching turntable 223 is provided with a release limiting slide groove 225. The end of the release limiting slide groove 225 is provided with a switching slide groove 227, and the end of the switching slide groove 227 is provided with a clamping limiting slide groove 226. The end of the switching slider 224 is located inside the release limiting slide groove 225, the switching slide groove 227, and the clamping limiting slide groove 226.

[0049] Furthermore, the automatic clamping component 22 also includes a switching turntable 223. The bottom of each rotating rod 221 is fixedly connected to the switching turntable 223, and the bottom of each switching turntable 223 is fixedly connected to a switching slider 224. Three sets of release limiting grooves 225 are formed from the inside out on the outer shell 1 below the switching turntable 223. Switching grooves 227 are formed on the outer shell 1 at both ends of the release limiting groove 225. Clamping limiting grooves 226 are formed on the outer shell 1 between the switching grooves 227 at both ends of the same set of release limiting grooves 225. The bottom of the set of switching sliders 224 near the center of the outer shell 1 on the switching turntable 223 below the same set of support blocks 213 is also provided. The innermost relaxation limit slide groove 225, switching slide groove 227 and clamping limit slide groove 226 are slidably connected in the closed loop slide groove. The bottom switching slider 224 of the switching turntable 223 below the same group of support blocks 213, away from the center of the outer shell 1, is slidably connected in the closed loop slide groove formed by the outermost relaxation limit slide groove 225, switching slide groove 227 and clamping limit slide groove 226. The bottom switching slider 224 of the two sets of switching turntable 223 below the middle of the same group of support blocks 213 is slidably connected in the closed loop slide groove formed by the middle relaxation limit slide groove 225, switching slide groove 227 and clamping limit slide groove 226.

[0050] The centers of the connected relaxation limiting slide 225 and clamping limiting slide 226 are the same, and the radius of the clamping limiting slide 226 is greater than the radius of the relaxation limiting slide 225.

[0051] The two ends of the relaxation limit slide 225 are connected to the two ends of the clamping limit slide 226 through the switching slide 227;

[0052] Four sets of 4 are fixedly connected to the inner top of the outer shell 1 above the relaxation limit slide 225. The four sets of 4 are separated into three areas. There is no top plate of the outer shell 1 in the two areas on both sides. The material tank 311 is fixedly connected in the middle area.

[0053] When in use, start the motor 211. The motor 211 drives the rotating support plate 212 to rotate. The rotating support plate 212 drives the support block 213 and the shaping punch 214 to rotate. When the shaping punch 214 rotates to below the opening of the top plate of the outer shell 1 on one side of the material tank 311, the glass that has been shaped above the shaping punch 214 is removed. Then continue to rotate the rotating support plate 212. When the rotating support plate 212 rotates to below the opening of the top plate of the outer shell 1 on the other side of the material tank 311, the glass plate is placed on the shaping punch 214. During the glass picking and placing process, since the ends of the switching sliders 224 around the shaping punch 214 are located inside the relaxation limit slide groove 225, the clamping cam 222 is located on the side away from the shaping punch 214, so that the clamping cam 222 will not affect the picking and placing of the glass.

[0054] After the glass is placed, continue rotating the rotating support plate 212. The shaping punch 214 drives the switching slider 224 to slide inside the relaxation limit groove 225 via the rotating rod 221 and the switching turntable 223. When the switching slider 224 slides into the switching groove 227, it drives the switching turntable 223 to rotate under the limit of the switching groove 227. The switching turntable 223 drives the clamping cam 222 to rotate via the rotating rod 221. The convex end of the clamping cam 222 rotates towards the shaping punch 214 and squeezes the glass from all sides to position and fix the glass. When the switching slider 224 slides into the clamping limit groove 226, the positioning and fixing of the glass is completed. At this time, continue rotating the rotating support plate 212. The rotating support plate 212 drives the glass into the interior of the outer shell 1 and heats and softens it. When the switching slider 224 slides inside the clamping limit groove 226, the glass is fixed. Initial heating and softening: When the switching slider 224 moves into the switching groove 227 on the other side of the clamping limit groove 226, the switching slider 224 drives the clamping cam 222 to rotate away from the shaping punch 214 and disengage from the glass under the limit of the switching groove 227. At this time, the glass is released, realizing automatic positioning, clamping and releasing of the glass. Since the initial heating and softening of the glass is completed at this time, the glass will not slip. At this time, the rotating support plate 212 continues to drive the glass to rotate and continue to heat the glass. The glass continues to soften and is spread on the shaping punch 214 from the top. Since the shaping punch 214 is convex and the softened glass is spread from the top of the shaping punch 214 to the bottom, the gas under the glass will be discharged in sequence. Therefore, there will be no defects caused by air bubbles in the glass. After the glass is spread, it is cooled and shaped and taken out from the opening of the top plate of the outer shell 1.

Since the upper end of the drive slider 336 is located within the push-limiting groove 332 when the shaping punch 214 is below the nozzle 316, this allows the switching turntable 331 to rotate. When rotating, under the limit of the pusher limiting groove 332, the drive slider 336 drives the push rod 335 and piston 334 to move towards the first feed hole 314. Since the second feed hole 322 and the third feed hole 324 are offset from each other at this time, the third feed hole 324 is blocked by the switching slide plate 321. At this time, the piston 334 pushes the medicine under the isolation plate 313 through the first feed hole 314 into the inside of the discharge groove 315. At this time, the medicine in the discharge groove 315 is continuously pushed out from the spray head 316 and sprinkled onto the shaping punch 214, thereby realizing the automatic spraying of the medicine.

[0070] Continue rotating the switching turntable 331. When the drive slider 336 slides into the interior of the restoration limiting groove 333, under the limitation of the restoration limiting groove 333, the drive slider 336 drives the piston 334 to move away from the first feed hole 314 via the push rod 335. At this time, since the upper end of the locking block 344 is inserted into the interior of the locking slot 342, the locking plate 341 and the switching slide plate 321 are locked. This prevents the switching slide plate 321 from moving erratically when the piston 334 moves away from the first feed hole 314. When the push rod 335 drives the switching protrusion 348 to move into the interior of the clearance groove 346, the inclined surface contacts the switching groove. The inner wall of 345 is compressed by the switching protrusion 348, causing the locking insert 344 to move downwards. The locking insert 344 then compresses the second spring 347, causing it to deform. When the switching groove 345 completely disengages from the locking slot 342, the piston 334 contacts the horizontal plate of the C-shaped plate 323. Since the locking plate 341 and the switching slide plate 321 are unlocked at this point, the piston 334 drives the C-shaped plate 323 to move away from the first feed hole 314. The C-shaped plate 323 then drives the switching slide plate 321 to move away from the first feed hole 314. The switching slide plate 321, through the limiting slide rod 325, compresses the first spring 326, causing the first... When spring 326 is compressed, the switching slide 321 moves the second feed hole 322 to align with the third feed hole 324. At this time, the agent above the partition plate 313 enters the area below the partition plate 313 through the second feed hole 322 and the third feed hole 324, thus completing the loading and temporary storage of the agent. When the next set of shaping punches 214 moves to the area below the ejector head 316, the driving slider 336 moves into the next set of push-limiting inclined grooves 332. At this time, under the limit of the push-limiting inclined grooves 332, the driving slider 336 drives the piston 334 to move closer to the limit of the first feed hole 314. At this time, under the action of the restoring force of the first spring 326, the first spring 326 drives the switching slide 326 to move. 1. The C-shaped plate 323 moves away from the drive slider 336. When the switching slide plate 321 moves to the point where the second feed hole 322 and the third feed hole 324 are misaligned, the switching protrusion 348 disengages from the switching groove 345. Under the action of the restoring force of the second spring 347, the second spring 347 drives the locking plug 344 to move upward and insert into the locking slot 342. At this time, the switching slide plate 321 is locked, so that the piston 334 squeezes the medicine below the isolation plate 313 through the first feed hole 314 and the spray head 316, thereby realizing the automatic replenishment and pre-storage of the medicine and automatic spraying, and ensuring the stability of the blockage of the third feed hole 324 during the automatic replenishment of the medicine.
