Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, and in particular to a spring end hook processing device. Background Technology

[0002] Spring hooks are hook-shaped tools that use the elasticity of a spring to achieve automatic closing, locking, or to provide cushioning and balancing functions. Their core design element is that small spring, which brings considerable convenience and safety.

[0003] Chinese Patent CN213968810U discloses a spring end hook processing device, including a base, a bracket, and a stamping block. The base is located at the bottom of the bracket, and the stamping block is located at the top of the bracket. Several support rods are provided on the base, and spring sleeve rods are mounted on the support rods. The stamping block has punch holes that match the spring sleeve rods, and a hand crank is also provided on the side of the stamping block. This technical solution, through the combined action of the stamping block and support rods, can directly process the spring end into a ring hook. Both the support rods and the stamping block are detachably connected and can be replaced appropriately according to the spring specifications, thus broadening its applicability. This technical solution has a simple structure and is easy to use.

[0004] However, the above technical solution has the following shortcomings: when processing the spring end, the worker has to manually push the stamping column to process the spring end by cranking the hand crank, and the spring needs to be manually placed on the support rod, which affects the processing efficiency of the spring end. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a spring end hook processing device that uses gear a, sector gear and return spring to drive the drive arm to move back and forth, allowing multiple processing tools to work together to automatically produce springs and spring end hooks, thereby improving the efficiency of spring production.

[0006] The present invention provides a spring end hook processing device, comprising: a frame on which multiple guide rails are arranged in a ring; processing components arranged in multiple groups in a ring on the frame, the processing components including a motor a mounted on the frame, a gear a mounted on the output end of the motor a, a sector gear rotatably mounted on the frame, a drive arm coaxially mounted on the sector gear, an adjusting block slidably mounted on the guide rails, a return spring mounted on the drive arm and the frame, and a processing tool mounted on the adjusting block; the drive arm is rotatably connected to the adjusting block, and the gear a is meshed with the sector gear; and auxiliary processing components are mounted on the frame and distributed among the multiple processing components.

[0007] Preferably, the auxiliary processing assembly includes an intermediate cylinder rotatably mounted on the frame, an auxiliary processing block bolted to the intermediate cylinder, an insertion tube mounted on the auxiliary processing block, a motor b mounted on the frame, and a gear b located at the output end of the motor b; the intermediate cylinder is provided with a gear ring portion, and the gear b meshes with the gear ring portion.

[0008] Preferably, the cross-section of the insertion tube is rectangular, and the outer circumferential surface of the insertion tube abuts axially with the inner circumferential surface of the intermediate cylinder.

[0009] Preferably, the wire feeding assembly includes a motor c and a guide rod mounted on the frame, a lead screw mounted on the output end of the motor c, a movable frame threaded onto the lead screw, a fixed frame mounted on the guide rod, and two clamping cylinders rotatably connected to each other on the movable frame and the fixed frame; the fixed frame is provided with a driving component.

[0010] Preferably, both pairs of clamping cylinders are provided with rounded corners.

[0011] Preferably, anti-slip rings are provided on the rounded corner surfaces of both clamping cylinders.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] In use, the steel wire extends through the auxiliary processing component. Motor A drives the drive arm to rotate reciprocally via gear transmission. The reciprocating rotation of the drive arm causes the adjusting block to move on the guide rail. During the movement of the adjusting block, the processing tool moves, allowing multiple processing tools to work together to sequentially coil the steel wire into spring ends, springs, and spring ends, and then cut it, thereby realizing the automatic production of springs and improving the spring production efficiency. To produce springs of different diameters and types, the processing tools and auxiliary processing components can be changed, and the program can be modified by connecting multiple motors A to a PLC system, thereby producing hooks and loops of different diameters and types.

Detailed Implementation

[0018] Example 1

[0019] like Figures 1-3 As shown, this embodiment proposes a spring end hook processing device, including a frame 1, processing components, and auxiliary processing components. The frame 1 is provided with multiple guide rails 3 arranged in a ring. Multiple sets of processing components are arranged in a ring on the frame 1, and the processing components are not distributed below the auxiliary processing components, thereby preventing the processed springs from falling onto the processing components and reducing the impact on the processing. The processing components include a motor a4 mounted on the frame 1, a gear a5 mounted on the output end of the motor a4, a sector gear 6 rotatably mounted on the frame 1, a drive arm 7 coaxially mounted on the sector gear 6, an adjusting block 8 slidably mounted on the guide rails 3, a return spring 19 mounted on the drive arm 7 and the frame 1, and a processing tool 9 mounted on the adjusting block 8. The drive arm 7 is rotatably connected to the adjusting block 8, and the gear a5 is meshed with the sector gear 6. The auxiliary processing components are mounted on the frame 1 and distributed among the multiple processing components.

[0020] In this embodiment, the steel wire extends through the auxiliary processing component. The motor a4 drives the drive arm 7 to rotate around the sector gear 6 as the axis by a certain amplitude through gear transmission. The gear a5 and the sector gear disengage, and the reset spring 19 drives the drive arm 7 to reset. The reciprocating rotation of the drive arm 7 will drive the adjusting block 8 to move back and forth on the guide rail 3. During the movement, the adjusting block 8 will drive the processing tool 9 to move, so that multiple processing tools 9 cooperate to sequentially coil the steel wire into spring ends, springs, and spring ends, and then cut them, thereby realizing the automatic production of springs. When producing springs of different diameters and types, the processing tools 9 and auxiliary processing components can be replaced, and the program can be changed through the PLC system connected to multiple motors a4, thereby producing hooks and loops of different diameters and types.

[0021] Example 2

[0022] like Figure 1 and Figure 3As shown, this embodiment proposes a spring end hook processing device. Compared with the first embodiment, in this embodiment, the auxiliary processing components include an intermediate cylinder 2 rotatably mounted on the frame 1, an auxiliary processing block 10 bolted to the intermediate cylinder 2, an insertion tube 11 mounted on the auxiliary processing block 10, a motor b12 mounted on the frame 1, and a gear b13 mounted on the output end of the motor b12. The intermediate cylinder 2 is provided with a gear ring 21, and the gear b13 meshes with the gear ring 21. The motor b12 drives the intermediate cylinder 2 to rotate through gear transmission. When processing springs of different diameters, insertion tubes 11 with different inner diameters are inserted into the intermediate cylinder 2. The auxiliary processing block 10 is fixed to the intermediate cylinder 2 by bolts, thereby preventing the steel wire from bending when subjected to resistance.

[0023] The cross-section of the insertion tube 11 is rectangular. The outer circumferential surface of the insertion tube 11 is axially abutted against the inner circumferential surface of the intermediate cylinder 2. The intermediate cylinder 2 will drive the insertion tube 11 to rotate by abutting the outer circumferential surface of the insertion tube 11 with its inner circumferential surface.

[0024] Example 3

[0025] like Figure 1 and Figure 3 As shown, this embodiment proposes a spring end hook processing device. Compared with Embodiment 1, in this embodiment, the wire feeding assembly includes a motor c and a guide rod 15 mounted on the frame 1, a lead screw 14 mounted on the output end of the motor c, a movable frame 16 threadedly connected to the lead screw 14, a fixed frame 17 mounted on the guide rod 15, and two clamping cylinders 18 rotatably connected to each other on the movable frame 16 and the fixed frame 17. The fixed frame 17 is equipped with a driving component. The motor c drives the lead screw 14 to rotate, and the movable frame 16 moves according to the diameter of the wire, allowing the clamping cylinders 18 to move the wire by clamping it. The driving component is a common bidirectional motor such as a motor.

[0026] Both pairs of clamping cylinders 18 are provided with rounded corners. The rounded corners allow the clamping points of the steel wire to be distributed in a ring shape, thereby improving the clamping effect of the steel wire. Anti-slip rings are provided on the rounded corner surfaces of both clamping cylinders 18. The anti-slip rings will deform during the clamping process, thereby increasing the friction between the anti-slip rings and the steel wire and improving the stable conveying of the steel wire.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
