Description

TECHNICAL FIELD

[0001] The utility model relates to spring processing technical field especially relates to a spring production wire straightening machine is with cutting device. BACKGROUND

[0002] Spring is an important basic part in industrial production, and is widely used in the fields of automobile, electronics, aerospace and mechanical manufacturing. The performance and quality of spring directly affect the service life and reliability of the product, and in the spring production process, wire straightening and cutting are one of the key links. The straightening degree of wire directly determines the consistency of the shape and elasticity of the spring, and the cutting accuracy will affect the size of the spring product and the smooth progress of subsequent processing. However, due to the high hardness and toughness of spring wire, the straightening and cutting process needs to be precisely controlled, especially on high-speed production lines, the efficiency and stability of the equipment are required to be higher. In modern manufacturing, how to realize efficient, accurate and automatic straightening and cutting has become an important direction of spring production technology development.

[0003] At present, most of the cutting devices of wire straightening machines still have certain technical defects, which are difficult to meet the production needs of high precision and high efficiency. The existing equipment often has poor straightening effect due to the high strength and high elasticity of the wire during straightening, and the straightened wire may still have certain bending or twisting, which affects the precision of subsequent processing. The cutting accuracy of the existing cutting device is low, especially in continuous and high-speed operation, the cutting position is easy to deviate or the cut is not neat. The transmission and cutting mechanism of many devices are designed to be complex, and it is not convenient to operate and maintain. Moreover, mechanical wear is easy to occur during long-term operation, which leads to the decrease of production stability. Some devices cannot well realize the linkage control of straightening and cutting, which may cause the position deviation or incomplete straightening of the wire during cutting, thereby affecting the processing efficiency and yield. Therefore, we provide a cutting device for spring production wire straightening machine. UTILITY MODEL CONTENTS

[0027] Example 1

[0028] like Figures 1-3 As shown, this utility model provides a technical solution: a cutting device for a spring production line straightening machine, comprising: a power mechanism 1, the power mechanism 1 including a side plate 11, an end plate 12 provided on both sides of the side plate 11, a rivet 13 provided between the side plate 11 and the end plate 12, a transmission rod 14 provided between the two side plates 11, a rotating wheel 15 provided on the transmission rod 14, a working motor 16 provided at one end of the transmission rod 14, a transmission gear 17 provided on the side of the rotating wheel 15 away from the working motor 16, and a cutting mechanism 2 provided between the two end plates 12;

[0029] The cutting mechanism 2 includes a straightening tube 21, a docking wheel 22 is provided on one side of the rotating wheel 15, a docking rod 23 is provided in the docking wheel 22, and a cutting blade 24 is provided at the end of the docking rod 23 away from the docking wheel 22.

[0030] One side of the end plate 12 is fixedly connected to one side of the side plate 11. The outer surface of the rivet 13 passes through the end plate 12 and is fixed to the side plate 11. The outer surface of the transmission rod 14 is limited to rotate between the two side plates 11. One end of the transmission rod 14 is connected to the working motor 16. The inner surface of the rotating wheel 15 is nested in the outer surface of the transmission rod 14. The inner surface of the transmission gear 17 is nested in the outer surface of the transmission rod 14. The two ends of the straightening tube 21 are respectively nested between the two end plates 12. The outer surface of the docking wheel 22 meshes with the outer surface of the rotating wheel 15. The outer surfaces of the two ends of the docking rod 23 are respectively nested in the docking wheel 22 and the cutting blade 24.

[0031] In this embodiment, when the operator uses this cutting device to cut the spring, the end of the spring wire can be introduced into the straightening tube 21. Then, by letting it pass through the straightening tube 21, the operator can start the working motor 16, so that the transmission rod 14 drives the docking wheel 22 to rotate through the rotating wheel 15. In this way, the docking rod 23 can cause the cutting blade 24 to rotate, thereby cutting the spring wire.

[0032] Example 2

[0033] like Figures 1-4 As shown, a straightening mechanism 3 is provided on the outer surface of the transmission gear 17. The straightening mechanism 3 includes a transmission belt 31. A driving gear 32 is provided at one end of the transmission belt 31. A linkage rod 33 is provided on one side of the driving gear 32. A straightening wheel 34 is provided on the outer surface of the linkage rod 33. One end of the transmission belt 31 is nested on the outer surface of the transmission gear 17, and the end of the transmission belt 31 away from the transmission gear 17 is nested on the outer surface of the driving gear 32. One end of the linkage rod 33 is welded to the driving gear 32, and the outer surface of the linkage rod 33 is nested in the straightening wheel 34.

[0034] In this embodiment, the operator can use the transmission gear 17 to drive the transmission belt 31 and the drive gear 32 to rotate, and then drive the straightening wheel 34 to rotate through the linkage rod 33. Then, one end of the spring wire is driven into the straightening tube 21 through the straightening wheel 34 for auxiliary straightening, thereby further improving its practicality in actual use.

[0035] Working principle:

[0036] like Figures 1-4 As shown, the end of the spring wire is introduced into the straightening tube 21, and the spring wire is fed into the cutting position through the straightening tube 21. Then, the operator starts the working motor 16, which causes the transmission rod 14 to drive the docking wheel 22 to rotate through the rotating wheel 15, thereby driving the docking rod 23, which in turn causes the cutting blade 24 to start rotating, achieving precise cutting of the spring wire.

[0037] In addition, in order to ensure that the spring wire remains in a straight line before cutting and improve the cutting efficiency, the staff can also drive the transmission belt 31 by means of the transmission gear 17, at the same time drive the gear 32 to rotate through the transmission belt 31, drive the linkage rod 33 to operate through the gear 32, so as to promote the straightening wheel 34 to rotate. In this way, the straightening wheel 34 can effectively pull the spring wire into the straightening pipe 21 and assist in straightening. The straightened spring wire is more flat, thereby improving the cutting precision and the running stability of the device in the cutting process.

[0038] It should be understood by those of ordinary skill in the art that the above discussion of any embodiment is only exemplary and is not intended to imply that the scope of the utility model (including claims) is limited to these examples; the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the utility model as described above, which are not provided in details for the sake of simplicity.
