Description

Technical Field

[0001] The present invention relates to the field of glass bending facilities, and particularly to a secondary forming bending die for automotive glass. Background Art

[0002] Bending is a glass processing technology, mainly used to heat glass products to a softened state, and then make them sag under their own weight and form a specific shape and curvature through a die. During the bending process, first, the glass is horizontally placed on the die, and then conveyed into the bending machine through a chain plate conveyor. The glass is heated by the bending machine to make it softened, and then sags under its own weight and adheres to the die to form a curved surface, thereby completing the bending operation of the glass.

[0003] However, when bending the front windshield of an automobile, due to the special shape of the front windshield of the automobile and its irregular edges, it is difficult to keep the front windshield of the automobile in a horizontal state when it is placed on the curved surface of the die. As a result, after subsequent bending and sagging, the curved surface of the glass is abnormal, seriously affecting the product quality. Summary of the Invention

[0004] The purpose of the present invention is to provide a secondary forming bending die for automotive glass to solve the problems raised in the above background art.

The other end of the push pin penetrates through the interior of the pin housing. The push pin is slidably matched with the pin housing.

[0010] Preferably, a pin cap is coaxially embedded at the other end of the push pin. The pin cap fits against the inner wall of the pin housing. A fixing spring is fixedly installed at the end of the pin cap. The end of the fixing spring is fixed to the inner side surface of the pin housing. Second guide wheels are installed at the front and rear ends of the lock belt base. First guide wheels are installed at both side edges of the lock belt base. The second guide wheels and the first guide wheels fit against the inner wall of the guide frame.

[0011] Preferably, the mounting member includes a mold frame fixedly installed in the middle of the lower end of the mold base. The middle of the lower end of the mold frame extends with a mounting head. A mounting seat is fitted on the outer surface of the mounting head. A bearing housing is installed at the front end of the mounting seat. An installation ear is elastically installed inside the bearing housing.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By providing multiple soft film steel belts, the automotive glass workpiece can be supported, enabling it to be placed horizontally on the mold base and then fed into the bending furnace for bending, thus ensuring the normal progress of the bending operation and guaranteeing product quality.

[0015] 2. When the automotive glass workpiece is completely softened by heating and the chain plate conveyor transports the workpiece, the pushing wheel moves from the horizontal section of the push rail to the inclined section and rolls along the inclined section to push the locking seat. At this time, the pushing pin slides within the pin housing to guide the locking seat, causing the locking ear to disengage from the locking hole on the locking belt seat under the drive of the locking seat. As a result, the locking belt seat can move without the restriction of the locking ear. At this moment, the soft film steel belt bends under the gravity of the counterweight and fits into the groove on the mold base. Meanwhile, the locking belt seat slides upward in the guide frame to adapt to the bending of the soft film steel belt, allowing the automotive glass workpiece supported by the soft film steel belt to sag and fit onto the mold base to form a curved surface, thereby completing the bending operation of the automotive glass workpiece. This process does not require manual operation by workers, effectively facilitating use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The present invention provides a technical solution: As Figure 1 - Figure 10A secondary forming bending die for automotive glass as shown includes a die base 1. On both sides of the die base 1, locking belt seats 9 are slidably installed. Between the two locking belt seats 9, multiple soft strip steel belts 10 are linearly arrayed. The locking belt seats 9 can tighten the soft strip steel belts 10 to make them straight. On both sides of the upper edge of the die base 1, multiple guide belt wheels 31 are linearly arrayed. The soft strip steel belts 10 are attached to the guide belt wheels 31, and the guide belt wheels 31 play a role in guiding the soft strip steel belts 10. On both sides of the lower edge of the die base 1, locking seats 11 are elastically installed. On the upper end face of the locking seat 11, a groove 13 is opened. The locking belt seat 9 is located inside the groove 13, and the groove 13 plays a role in accommodating the locking belt seat 9. At the inner upper edge of the groove 13, a locking ear 14 extends. The locking seat 11 plays a role in carrying the locking ear 14. The locking ear 14 passes through the middle of the locking belt seat 9, and the locking ear 14 plays a role in fixing the locking belt seat 9. One end of the locking seat 11 is connected to a driving wheel 12. On the side of the driving wheel 12, a pushing rail 7 is attached. The driving wheel 12 can be pushed by the pushing rail 7 to drive the locking ear 14 on the locking seat 11 to move, so that the fixed locking belt seat 9 can move. On the side of the pushing rail 7, a mounting bracket 8 is fixedly installed. The mounting bracket 8 can be fixed to the frame of the chain conveyor by welding or other means, that is, the pushing rail 7 is fixed. When the chain conveyor drives the die base 1 to move, the pushing rail 7 can push the driving wheel 12. At the middle of the lower end of the die base 1, a mounting part is provided.

[0029] On both sides of the upper end face of the die base 1, multiple wheel grooves 32 are linearly arrayed. The guide belt wheels 31 are installed inside the wheel grooves 32, and the wheel grooves 32 play a role in carrying the guide belt wheels 31. On the upper end face of the die base 1, multiple belt grooves 33 are linearly arrayed. The soft strip steel belts 10 are located above the belt grooves 33. After being bent, the soft strip steel belts 10 will fit into the belt grooves 33, making the soft strip steel belts 10 and the die base 1 coplanar. After the automotive glass workpiece 36 softens and sags and fits on the die base 1, the surface of the automotive glass workpiece 36 can remain smooth. A locking hole 29 is penetrated through the middle of the locking belt seat 9, and the locking ear 14 fits inside the locking hole 29. The locking hole 29 plays a role in cooperating with the locking ear 14.

[0030] Below the die base 1, three counterweight blocks 26 are evenly distributed. On the upper end face of the counterweight blocks 26, multiple connecting pieces 25 linearly extend. The counterweight blocks 26 play a role in bending the soft strip steel belts 10. The ends of the connecting pieces 25 are fixed to the soft strip steel belts 10, and the connecting pieces 25 play a connecting role. Three through holes 27 are evenly distributed and penetrated through the inner bottom surface of the belt grooves 33. The connecting pieces 25 pass through the inside of the through holes 27, and the through holes 27 play a role in allowing the connecting pieces 25 to pass through the die base 1 normally.

[0031] Both ends of the lock belt seat 9 are provided with guide frames 6. On the opposite surfaces of the two guide frames 6, protruding claws 35 are fixedly installed. The protruding claws 35 play a role in fixing the guide frames 6. The end of the protruding claw 35 is fixed to the mold base 1. A connecting frame 28 is fixedly installed between the two protruding claws 35. The guide frame 6 plays a role in guiding the lock belt seat 9.

[0032] In the middle of the connecting frame 28, a housing frame 30 is fixedly installed. At the end of the housing frame 30, two pin housings 16 are fixedly installed. The housing frame 30 plays a role in fixing the pin housings 16. At the end of the pin housing 16, a push pin 15 is coaxially arranged. The pin housing 16 plays a role in carrying the push pin 15. One end of the push pin 15 is fixed to the other end of the locking seat 11. The push pin 15 can push the locking seat 11, so that the locking ear 14 on the locking seat 11 and the lock hole 29 on the lock belt seat 9 are engaged. The other end of the push pin 15 penetrates through the inside of the pin housing 16, and the push pin 15 is in sliding fit with the pin housing 16.

[0033] At the other end of the push pin 15, a pin cap 18 is coaxially embedded. The pin cap 18 fits against the inner wall of the pin housing 16. The pin cap 18 plays a role in being pushed by the fixing spring 17. At the end of the pin cap 18, a fixing spring 17 is fixedly installed. The end of the fixing spring 17 is fixed to the inner side surface of the pin housing 16. The fixing spring 17 plays a role in pushing out the push pin 15. At the front and rear ends of the lock belt seat 9, second guide wheels 24 are installed. At the two side edges of the lock belt seat 9, first guide wheels 23 are installed. The second guide wheels 24 and the first guide wheels 23 fit against the inner wall of the guide frame 6. The second guide wheels 24 and the first guide wheels 23 play a role in reducing the friction between the lock belt seat 9 and the guide frame 6.

[0034] The installation part includes a mold frame 2 fixedly installed in the middle of the lower end of the mold base 1. At the middle of the lower end of the mold frame 2, an installation head 3 extends. The mold frame 2 plays a role in carrying the installation head 3. An installation seat 4 is fitted on the outer surface of the installation head 3. The installation seat 4 can be fixed to the chain plate of the chain conveyor by welding or other means. After the installation head 3 and the installation seat 4 are fixed together, the mold base 1 can be installed on the chain conveyor, so that when the chain conveyor is working, it can drive the mold base 1 to move. At the front end of the installation seat 4, a bearing shell 5 is installed. Inside the bearing shell 5, an installation ear 20 is elastically installed. The bearing shell 5 plays a role in carrying the installation ear 20. The installation ear 20 extends out from the rear end of the bearing shell 5. The installation ear 20 sequentially penetrates through the front end of the installation seat 4 and the front end of the installation head 3. The installation ear 20 plays a role in fixing the installation seat 4 and the installation head 3 together.

[0035] The front end of the mounting head 3 is provided with a fixing groove 19, and the end of the mounting ear 20 fits inside the fixing groove 19. The fixing groove 19 functions to engage with the mounting ear 20. The rear edge of the upper end of the mounting ear 20 is inclined, which facilitates being pushed by the mounting head 3. A pull rod 22 is fixedly installed at the front end of the mounting ear 20. The pull rod 22 penetrates through the front end of the bearing shell 5. The pull rod 22 is slidably engaged with the bearing shell 5. The pull rod 22 functions to facilitate pulling the mounting ear 20. A spring body 21 is wound around the outer side of the pull rod 22. One end of the spring body 21 is fixed to the front end inside the bearing shell 5, and the other end of the spring body 21 is fixed to the mounting ear 20. The spring body 21 can push the mounting ear 20 so that the mounting ear 20 can be engaged in the fixing groove 19 on the mounting head 3. A shell base 34 is fixedly installed at the lower end of the bearing shell 5. The shell base 34 functions to fix the bearing shell 5. The end of the shell base 34 is fixed to the mounting base 4.

[0036] During use, place the mold base 1 on the chain conveyor. At this time, the mounting head 3 is inserted into the mounting base 4, and the mounting ear 20 is pushed under the action of the inclined surface on the mounting ear 20, causing the mounting ear 20 to shift laterally. At this time, the spring body 21 contracts and deforms. When the mounting head 3 completely enters the mounting base 4, the spring body 21 restores its deformation and pushes the mounting ear 20 so that the mounting ear 20 enters the fixing groove 19 on the mounting head 3 to fix the mounting head 3, thereby fixing the mold base 1 on the chain conveyor. Then, place the automotive glass workpiece 36 to be baked and bent on the mold base 1. At this time, multiple soft strip steel belts 10 will support the automotive glass workpiece 36, making the automotive glass workpiece 36 be placed on the mold base 1 in a horizontal state. Then, the chain conveyor drives the automotive glass workpiece 36 on the mold base 1 to move, sending it into the baking and bending machine for heating. At this time, the pushing wheel 12 just moves to the horizontal section of the pushing rail 7. After the automotive glass workpiece 36 is completely softened by heating, the chain conveyor will convey the automotive glass workpiece 36. At this time, the pushing wheel 12 will move from the horizontal section of the pushing rail 7 to the inclined section and roll along the inclined section to push the locking seat 11. At this time, the pushing pin 15 slides inside the pin shell 16 to guide the locking seat 11, so that the locking ear 14 can be driven by the locking seat 11 to disengage from the locking hole 29 on the locking belt seat 9, enabling the locking belt seat 9 to move without being restricted by the locking ear 14. At the same time, the soft strip steel belt 10 bends under the gravity of the counterweight 26 and fits into the groove 33 on the mold base 1. At this time, the locking belt seat 9 slides upward in the guide frame 6 to adapt to the bending of the soft strip steel belt 10, allowing the automotive glass workpiece 36 supported by the soft strip steel belt 10 to sag and fit onto the mold base 1 to form a curved surface, thereby completing the baking and bending operation of the automotive glass workpiece 36. Subsequently, the chain conveyor sends the baked and bent automotive glass workpiece 36 out of the baking and bending machine for cooling and forming.
