Description

Technical Field

[0001] This utility model relates to the field of automotive seat frame manufacturing technology, specifically a bending device for automotive seat frame manufacturing. Background Technology

[0002] The production and processing of automobiles includes the production of car seat frames. When producing car seat frames, it is often necessary to bend the raw material rods of the frame to obtain the shape of the seat frame, so bending equipment is required.

[0003] According to a public notice (No. CN220658856U) regarding a bending device for producing automotive seat frames, the aforementioned application utilizes a first bidirectional lead screw to drive a moving frame and a pressure block to move closer together via a first moving block and a second moving block, thereby allowing the pressure block to bend the frame. This method uses the force of movement to make the pressure block fit against the frame rod. However, the speed of movement is not considered during the movement process. Excessive movement speed can cause a large impact force when the frame comes into contact with the bending equipment, which may cause the frame to shift at the moment of contact. Even if the frame position is precisely aligned with the bending head before contact, the displacement caused by the collision may cause the bending position to deviate. To address this issue, we propose a bending device for producing automotive seat frames. Utility Model Content

[0004] The purpose of this invention is to provide a bending device for producing automotive seat frames, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending device for producing automotive seat frames, comprising a bending seat, a bending head fixedly mounted on the surface of the bending seat, the surface of the bending seat fitting against the bottom of a support frame, a flat rod fixedly mounted on the inner wall of the support frame, the flat rod penetrating a clamping plate and slidably connected to the clamping plate, one end of a spring fixedly connected to the surface of the clamping plate, the other end of the spring fixedly mounted on the inner wall of the support frame, and a control component for mitigating the impact force on the automotive seat frame provided within the bending seat, the control component comprising: a connecting plate, the surface of the connecting plate fixedly connected to the surface of the support frame, a support block fixedly mounted on the bottom of the connecting plate, the support block penetrating the bending seat and slidably connected to the bending seat, a moving block fixedly mounted on the bottom of the support block, the surface of the moving block hinged to a movable rod, the surface of the movable rod fixedly connected to one side of a torsion spring, and the other side of the torsion spring fixedly mounted on the surface of the moving block, thereby preventing the frame from deforming or shifting due to excessive impact force caused by excessive speed.

[0006] Preferably, the control assembly further includes a moving component, which includes a threaded rod that passes through and is threadedly connected to the moving block, and a threaded rod that passes through and is rotatably connected to the bending seat. When the threaded rod rotates, the moving block can slide stably along the inner wall of the bending seat.

[0007] Preferably, a protrusion is fixedly installed on the inner wall of the bending seat, the surface of the bending seat is rotatably connected to the surface of the circular plate, the surface of the circular plate is fixedly connected to the surface of the threaded rod, and the threaded rod can rotate synchronously when the circular plate rotates on the surface of the bending seat.

[0008] Preferably, a circular block is fixedly installed on the surface of the circular plate, and a slot is formed on the surface of the circular plate to restrict the rotation of the circular plate.

[0009] Preferably, a fixing ring is fixedly installed on the surface of the bending seat. The fixing ring is penetrated by the circular block and rotatably connected to the circular block. When the fixing block is moved by the circular block, the circular block can perform circumferential motion within the fixing ring.

[0010] Preferably, the fixing ring is penetrated by the push rod and slidably connected to the push rod, and a locking block is fixedly installed on the surface of the push rod. When the push rod is abutted, the locking block fixed on the surface of the push rod can move longitudinally synchronously.

[0011] Preferably, the locking block is penetrated by a fixing rod and slidably connected to the fixing rod. The fixing rod is fixedly installed on the inner wall of the fixing ring. The surface of the fixing rod is fixedly connected to one end of the second spring. The other end of the second spring is fixedly installed on the surface of the locking block. When the locking block is no longer under force, it can bounce off the surface of the fixing rod with the support of the second spring.

[0012] Compared with the prior art, this utility model provides a bending device for producing automotive seat frames, which has the following advantages:

[0013] 1. This bending equipment for producing automotive seat frames is equipped with a control component. When a circular block drives a circular plate to rotate on the surface of the bending seat, a threaded rod fixed to the surface of the circular plate can rotate synchronously within the bending seat. As the threaded rod rotates, a moving block can slide along the inner wall of the bending seat. When the moving block moves, the movable rod hinged to the inner wall of the moving block will abut against the surface of the protrusion. When the movable rod is abutted, it can be folded under the support of a torsion spring, thus slowing down the movement speed of the moving block. This achieves the purpose of slow movement of the frame rod, avoiding deformation and displacement of the frame due to excessive impact force caused by excessive speed.

[0014] 2. The bending equipment for producing car seat frames is equipped with a moving part. Since the surface of the circular plate has a slot, when the push rod inside the fixed ring is pushed, the locking block fixed to the surface of the push rod will move out of the slot on the surface of the circular plate, thereby releasing the restriction on the circular plate and the threaded rod. This method enhances the safety of the equipment during use and avoids the displacement of the support frame due to accidental contact. Attached Figure Description

[0021] like Figures 1-5As shown, this utility model provides a technical solution: a bending device for producing automotive seat frames, including a bending seat 1, a bending head 2 fixedly mounted on the surface of the bending seat 1, the surface of the bending seat 1 being in contact with the bottom of a support frame 3, a flat rod 4 fixedly mounted on the inner wall of the support frame 3, the flat rod 4 passing through a clamping plate 5 and slidably connected to the clamping plate 5, one end of a spring-6 fixedly connected to the surface of the clamping plate 5, the other end of the spring-6 fixedly mounted on the inner wall of the support frame 3, and a control component 7 for mitigating the impact force on the automotive seat frame provided inside the bending seat 1, the control component 7 including: a connecting plate 71, the surface of the connecting plate 71 being fixedly connected to the surface of the support frame 3, and a support block 72 fixedly mounted on the bottom of the connecting plate 71. Block 72 passes through and is slidably connected to bending seat 1. A movable block 73 is fixedly installed at the bottom of block 72. The surface of movable block 73 is hinged to movable rod 74. The surface of movable rod 74 is fixedly connected to one side of torsion spring 75. The other side of torsion spring 75 is fixedly installed on the surface of movable block 73. When movable block 73 moves, movable rod 74 hinged to the inner wall of movable block 73 will abut against the surface of protrusion 762. When movable rod 74 is abutted, it can be folded under the support of torsion spring 75, so that the moving speed of movable block 73 can be slowed down, thereby achieving the purpose of slow movement of the skeleton rod and avoiding deformation and displacement of the skeleton due to excessive speed and large impact force.

[0022] The control assembly 7 also includes a moving component 76, which includes a threaded rod 761. The threaded rod 761 passes through and is threadedly connected to the moving block 73. The threaded rod 761 also passes through and is rotatably connected to the bending seat 1. When the threaded rod 761 rotates, the moving block 73 can slide stably along the inner wall of the bending seat 1. A protrusion 762 is fixedly installed on the inner wall of the bending seat 1. The surface of the bending seat 1 is rotatably connected to the surface of the circular plate 763. The surface of the circular plate 763 is fixedly connected to the surface of the threaded rod 761. When the circular plate 763 rotates on the surface of the bending seat 1, the threaded rod 761 can rotate synchronously. A circular block 765 is fixedly installed on the surface of the circular plate 763. A slot 764 is formed on the surface of the circular plate 763. The slot 764 can limit the rotation of the circular plate 763. A fixed ring 766 is fixedly installed on the surface of the bending seat 1. The fixed ring 766 is rotatably connected to the circular block 765 through which the fixed ring 766 passes. When the fixed ring 766 is moved by the circular block 765, the circular block 765 can perform circular motion within the fixed ring 766. The fixed ring 766 is slidably connected to the push rod 767 through which the fixed ring 766 passes. A locking block 768 is fixedly installed on the surface of the push rod 767. When the push rod 767 is abutted, the locking block 768 fixed on the surface of the push rod 767 can move longitudinally synchronously. The locking block 768 is slidably connected to the fixed rod 769 through which the fixed rod 769 passes. The fixed rod 769 is fixedly installed on the inner wall of the fixed ring 766. The surface of the fixed rod 769 is fixedly connected to one end of the second spring 760. The other end of the second spring 760 is fixedly installed on the surface of the locking block 768. When the locking block 768 is no longer under force, it can spring up from the surface of the fixed rod 769 with the support of the second spring 760.

[0023] In this invention, during use, the car seat frame rod to be bent is inserted into the support frame 3. The clamping plate 5 inside the support frame 3, under the action of spring 6, adapts to the size of the frame rod and initially fixes it. After fixing, the push rod 767 is pushed against the surface of the fixing ring 766. The push rod 767, under the force, causes the locking block 768 to move longitudinally against the surface of the fixing rod 769 under the support of spring 760. After the locking block 768 moves, it can exit through the slot 764 opened on the surface of the circular plate 763. After removal, maintain the force pushing the push rod 767 and rotate the circular block 765 on the surface of the fixed ring 766. When the circular block 765 rotates, the circular plate 763 fixed to the surface of the circular block 765 can drive the threaded rod 761 to rotate synchronously within the bending seat 1. When the threaded rod 761 rotates, the moving block 73 can slide along the inner wall of the bending seat 1. When the moving block 73 moves, the movable rod 74 hinged to the inner wall of the moving block 73 will abut against the surface of the protrusion 762. When the movable rod 74 is abutted... The frame rod can be folded under the support of the torsion spring 75, which slows down the movement of the moving block 73, thus achieving the purpose of slow movement of the frame rod. This avoids deformation and displacement of the frame rod due to excessive impact force caused by excessive speed. When the moving block 73 moves, the support block 72 fixed on the surface of the moving block 73 can drive the connecting plate 71 to slide synchronously on the surface of the bending seat 1. When the connecting plate 71 moves, the support frame 3 fixed on the surface of the connecting plate 71 can drive the frame rod to move synchronously towards the surface of the bending head 2. When it contacts the surface of the bending head 2, the frame rod gradually bends. The spring 6 in the support frame 3 can adapt to the bending trajectory of the frame rod, preventing it from loosening and shifting within the support frame 3. At the same time, this method can perform slow bending. Slow movement helps the frame rod to be evenly stressed during the bending process. When the frame rod slowly contacts the bending head 2 and begins to bend, the stress can be more evenly distributed in the bending area, reducing defects such as surface scratches and wrinkles caused by local stress concentration.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
