Description

Technical Field

[0001] The present invention relates to the technical field of spring processing, and particularly to a spring winding device for spring processing that is convenient for adjustment. Background Technique

[0002] In the process of spring processing, the spring winding device is one of the core devices. Its main function is to wind metal wire (such as steel wire, stainless steel wire, etc.) into a spiral spring. In actual processing, the wire feeding mechanism smoothly feeds the metal wire onto the mandrel of the winding device, and the drive motor on the spring winding device is started to drive the mandrel to rotate. The wire is wound into a spring under the guidance of the mandrel.

[0003] Generally, the spring winding device lacks a length adjustment structure. This results in that when the spring is being wound, its length, that is, the number of winding turns, needs to be visually observed. When the required length is reached, the drive motor is manually turned off to stop the winding. This not only increases the burden on the operator, but also increases the operation difficulty and error rate. Summary of the Invention

[0004] The purpose of the present invention is to provide a spring winding device for spring processing that is convenient for adjustment, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A spring winding device for spring processing that is convenient for adjustment, including a frame, a first drive motor, a support frame, and a spring winding mandrel. One end of the top of the frame is provided with a support frame, and one side of the support frame is provided with a fixed clamping member through a rotating seat. The inside of the fixed clamping member clamps the spring winding mandrel. One end of the support frame away from the spring winding mandrel is fixed with a first drive motor, and the output end of the first drive motor is connected to the rotating seat through a roller. A bayonet is opened at one end of the spring winding mandrel, and a limiting support is arranged below the other end of the spring winding mandrel. A lead screw is arranged inside the frame, and a drive block is sleeved on the lead screw. A second drive motor is arranged below the support frame, and the output end of the second drive motor is connected to the lead screw. Sensors are evenly distributed on one side of the limiting support close to the fixed clamping member.

[0006] Preferably, a guide rod is arranged inside the frame below the lead screw, and the bottom of the drive block is movably sleeved with the guide rod through a guide sleeve.

[0007] Preferably, sliders are arranged at both ends of the side of the rotating seat close to the support frame, and annular chutes matching the sliders are opened on the side of the support frame close to the rotating seat.

[0008] Preferably, clamping arms are arranged at both ends of one side of the fixed clamping member, and clamps are arranged on the clamping arms. The clamps are clamped and fixed to one end of the spring winding mandrel.

[0009] Preferably, a second cylinder is fixed to one end of the fixed clamping member, and a movable block is provided at the output end of the second cylinder through a telescopic rod. Both sides of the movable block are uniformly connected to the clamping arms through transmission rods.

[0010] Preferably, limiting grooves are provided at both ends of one side of the fixed clamping member, and limiting blocks are connected to the limiting grooves on one side of one end of each clamping arm close to the limiting grooves.

[0011] Preferably, guiding balls are uniformly distributed on the top surface of the limiting support, and the guiding balls are all in contact with the surface of the spring winding core shaft.

[0012] Preferably, a first cylinder is provided at the top of the driving block, and the output end of the first cylinder is connected to the limiting support through a telescopic rod.

[0013] A spring winding method for spring processing that is convenient for adjustment. First, adjust the position of the limiting support according to the length of the spring to be wound. When adjusting, drive the lead screw to rotate through a second drive motor, so that the driving block moves along the lead screw to adjust the position of the limiting support. The distance between the limiting support and the upper bayonet of the spring winding core shaft is the length of the wound spring. Then, feed the spring raw material onto the spring winding core shaft, and insert one end of it into the bayonet. Start the first drive motor to drive the spring winding core shaft to rotate, and wind the spring raw material around the spring winding core shaft. Finally, when one end of the spring raw material touches the sensor on one side of the limiting support, the sensor transmits a signal to the control system, thereby controlling the first drive motor to shut down and stop winding, so that the position of the limiting support can be automatically adjusted according to different length requirements of the wound spring, and the winding can be automatically controlled to stop. When springs with different diameters need to be processed, the spring winding core shaft can be quickly replaced. At this time, drive the movable block to push to the right through the second cylinder, so as to push the clamping arms apart through the transmission rods, drive the clamps to separate from each other, and thus the spring winding core shaft can be disassembled and replaced. Quickly replacing the spring winding core shaft enables the winding device to flexibly adapt to the production of various specifications of springs.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The spring winding device for easy adjustment is equipped with a frame, a first driving motor, a fixed clamping member, a spring winding mandrel, a bayonet, a lead screw, a driving block, a limiting support and a sensor. The second driving motor drives the lead screw to rotate, causing the driving block to move along the lead screw, thereby adjusting the position of the limiting support according to the length of the spring to be wound. The distance between the limiting support and the bayonet is the length of the wound spring. Then, the spring raw material is fed onto the spring winding mandrel, and one end of it is inserted into the bayonet. The first driving motor is started to drive the spring winding mandrel to rotate, and the spring raw material is wound around the spring winding mandrel. When one end of the spring raw material touches the sensor on one side of the limiting support, the sensor transmits a signal to the control system, thereby controlling the first driving motor to shut down and stop winding. This enables automatic adjustment of the position of the limiting support according to different length requirements of the wound spring and automatic control of the stop of winding, reducing manual intervention and improving the processing efficiency of the spring.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0023] Please refer to Figures 1-5 , an embodiment provided by the present invention: a spring winding device for spring processing that is easy to adjust, including a frame 1, a first driving motor 4, a support frame 5, and a spring winding mandrel 9. One end of the top of the frame 1 is provided with a support frame 5, and a fixed clamping member 7 is provided on one side of the support frame 5 through a rotating seat 6. A spring winding mandrel 9 is clamped inside the fixed clamping member 7;

[0024] One end of the support frame 5 away from the spring winding mandrel 9 is fixed with a first driving motor 4, and the output end of the first driving motor 4 is connected to the rotating seat 6 through a roller;

[0025] A bayonet 10 is opened at one end of the spring winding mandrel 9. The spring raw material is fed onto the spring winding mandrel 9, and one end of it is inserted into the bayonet 10. The first driving motor 4 is started to drive the spring winding mandrel 9 to rotate, and the spring raw material is wound around the spring winding mandrel 9;

[0026] Sliders 23 are provided at both ends of the side of the rotating seat 6 close to the support frame 5. An annular chute matching the sliders 23 is opened on the side of the support frame 5 close to the rotating seat 6, making the rotation of the fixed clamping member 7 and the spring winding mandrel 9 more stable;

[0027] A limit support 11 is provided below the other end of the spring winding mandrel 9. A lead screw 2 is provided inside the frame 1, and a driving block 12 is sleeved on the lead screw 2. A first cylinder 13 is provided at the top of the driving block 12, and the output end of the first cylinder 13 is connected to the limit support 11 through a telescopic rod;

[0028] A second driving motor 3 is provided below the support frame 5, and the output end of the second driving motor 3 is connected to the lead screw 2;

[0029] The position of the limit support 11 can be adjusted according to the length of the spring to be wound. During adjustment, the second driving motor 3 drives the lead screw 2 to rotate, so that the driving block 12 moves along the lead screw 2 to adjust the position of the limit support 11. The distance between the limit support 11 and the bayonet 10 on the spring winding mandrel 9 is the length of the wound spring;

[0030] At the same time, the limit support 11 can be driven by the first cylinder 13 to adjust the height so that it contacts the bottom of the spring winding mandrel 9;

[0031] A guide rod 14 is provided inside the frame 1 below the lead screw 2. The bottom of the driving block 12 is movably sleeved with the guide rod 14 through a guide sleeve 15 to guide and limit the driving block 12;

[0032] On one side of the limit support 11 close to the fixed clamping member 7, sensors 17 are evenly distributed. During the spring winding process, when one end of the spring raw material touches the sensor 17 on one side of the limit support 11, the sensor 17 transmits a signal to the control system, thereby controlling the first driving motor 4 to close and stop winding.

[0033] It enables the position of the limit support 11 to be automatically adjusted according to different length requirements of the wound spring, and can automatically control the stop of winding, reducing manual intervention and improving the processing efficiency of the spring.

[0034] Guide balls 16 are evenly distributed on the top surface of the limit support 11, and all the guide balls 16 are in contact with the surface of the spring winding core shaft 9, playing a role of support and guidance during the rotation of the spring winding core shaft 9 and reducing friction.

[0035] At both ends of one side of the fixed clamping member 7, clamping arms 19 are provided, and clamps 8 are provided on the clamping arms 19. The clamps 8 are clamped and fixed to one end of the spring winding core shaft 9.

[0036] A second cylinder 21 is fixed to one end of the fixed clamping member 7, and a movable block 22 is provided at the output end of the second cylinder 21 through a telescopic rod. Both sides of the movable block 22 are evenly connected to the clamping arms 19 through transmission rods 20.

[0037] When springs with different diameters need to be processed, the spring winding core shaft 9 can be quickly replaced. At this time, the second cylinder 21 drives the movable block 22 to push to the right, thereby pushing the clamping arms 19 to separate through the transmission rods 20, driving the clamps 8 to separate from each other, so that the spring winding core shaft 9 can be disassembled and replaced. The quick replacement of the spring winding core shaft 9 enables the winding device to flexibly adapt to the production of springs of various specifications and improves the versatility of the equipment.

[0038] Limit grooves 18 are provided at both ends of one side of the fixed clamping member 7, and one end of the clamping arm 19 is connected to the limit groove 18 through a limit block on the side close to the limit groove 18, playing a role of limiting during the movement of the clamping arm 19.

[0039] The specific model specifications of the first driving motor 4, the second driving motor 3, the first cylinder 13, the second cylinder 21, and the sensor 17 need to be determined by selection calculation according to the specification parameters of the device. The selection calculation method is prior art, so it will not be elaborated in detail.

[0040] Working principle: When the embodiment of the present application is in use, the position of the limit support 11 is adjusted according to the length of the spring to be wound. During adjustment, the second driving motor 3 drives the lead screw 2 to rotate, so that the driving block 12 moves along the lead screw 2 to adjust the position of the limit support 11. The distance between the limit support 11 and the upper bayonet 10 on the spring winding mandrel 9 is the length of the wound spring. Then, the spring raw material is sent onto the spring winding mandrel 9, and one end of it is inserted into the bayonet 10. The first driving motor 4 is started to drive the spring winding mandrel 9 to rotate, and the spring raw material is wound around the spring winding mandrel 9. When one end of the spring raw material touches the sensor 17 on one side of the limit support 11, the sensor 17 transmits a signal to the control system, thereby controlling the first driving motor 4 to turn off and stop winding. This enables the automatic adjustment of the position of the limit support 11 according to different length requirements of the wound spring and can automatically control the stop of winding, reducing manual intervention and improving the processing efficiency of the spring. In addition, when springs with different diameters need to be processed, the spring winding mandrel 9 can be quickly replaced. At this time, the second cylinder 21 drives the movable block 22 to push to the right, so as to drive the clamping arms 19 to separate through the transmission rod 20, driving the clamps 8 to separate from each other, and thus the spring winding mandrel 9 can be disassembled and replaced. The quick replacement of the spring winding mandrel 9 enables the winding device to flexibly adapt to the production of springs of various specifications and improves the versatility of the equipment.

[0041] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present invention.
