Description

Technical Field

[0001] The present invention relates to the technical field of spring washer production, and specifically relates to a spring washer forming device and a using method thereof. Background Art

[0002] The production process of spring washers mainly includes material selection, stamping forming, heat treatment, sizing, cleaning and degreasing, surface treatment, and quality inspection. In production, mechanical improvement measures such as multi-roll rolling forming and optimized winding devices can improve processing accuracy and efficiency; at the same time, detection devices such as Hall effect sensors and rotary position sensors are used to monitor the production status in real time to ensure product quality and production stability.

[0003] During the forming process, it is necessary to extrude and stretch the blank to reduce its cross-sectional area and extend its length. When stretching, pressure is usually applied to the hot or cold steel bar by one or more pairs of rotating rollers to cause plastic deformation. After long-term use, the rollers will have a certain amount of wear and consumption. At this time, the final stretched blank will be thicker than the normal blank, but now it is impossible to effectively monitor it, which will have a certain impact on the subsequent processing process.

[0004] When the thickened blank is extruded and deformed subsequently, due to the increase in the blank, the load on the extrusion roller will increase, which will cause damage to the extrusion roller and affect the production of the entire device. Summary of the Invention

[0005] In order to solve the above problems existing in the prior art, the present invention provides a spring washer forming device, which has the advantages of monitoring the size of the blank in time and reminding the staff, and at the same time can cut off the redundant material to avoid affecting the subsequent processing.

The rolling wheel is detachably installed on the connecting rod. The side end face of the connecting rod also extends to both sides, and its bottom abuts against the detection synchronizing rod.

[0008] Preferably, the thread directions inside the two adjustment sliders are opposite.

[0009] Preferably, a detection mounting block is fixed to one side end face of the detection synchronizing rod. The detection mounting block extends to the outside and slides inside the rolling device. A bracket is movably connected inside the detection mounting block. The bracket is fixed to the detection mounting block through a detection spring. A trigger module is fixed to the side end face of the detection mounting block away from the rolling device.

[0010] Preferably, a detection wheel is rotatably connected to the bottom of the bracket. Contact blocks extend outward from both side end faces of the bracket. The contact blocks contact the trigger module, and a part of the trigger module extends downward.

[0011] Preferably, an installation box body is provided on the primary extrusion device. The left and right sides of the installation box body are hollow and penetrated. A first extrusion roller and a shearing roller are provided inside the installation box body. The first extrusion roller is rotatably installed, and the shearing roller is movably installed.

[0012] Preferably, there are two first extrusion rollers, including extrusion rollers. Connecting gears are provided on both sides of the extrusion rollers. The connecting gears on the same side of the two extrusion rollers are meshed with each other. The extrusion rollers and the connecting gears are fixed together through a rotating shaft. A motor is installed on the rotating shaft at the bottom of one of the extrusion rollers.

[0013] Preferably, two through tracks are provided inside the installation box body. The shearing roller includes a shearing roller and a hydraulic cylinder. The shearing roller slides inside the track. The shearing roller is power-connected to the first extrusion roller through a belt. The track is arc-shaped, and the center of the arc is the same as the center of the first extrusion roller. Two mounting columns are fixed to the upper and lower side end faces of the installation box body. The hydraulic cylinder is movably installed on each mounting column. A hydraulic rod is telescopically installed inside the hydraulic cylinder. The hydraulic rod is sleeved on the shearing roller. Two groups of shearing blades are provided on the outer peripheral side of each shearing roller. The distance between the two groups of shearing blades on one side is the same as the width of the spring gasket.

[0014] Preferably, the secondary extrusion device is provided with four flat extrusion rollers, and a square through hole is formed between the four flat extrusion rollers. A bending member and a cutting member are arranged in the forming device.

[0015] A method for using a spring washer forming device, the method steps are as follows: S1: Pass the blank (thick steel bar) through the die hole of the rolling device, that is, the hole between the two rolling wheels, and force it to pass through under the extrusion of tension and thrust, so that its cross-sectional area is reduced and its length is extended.

[0016] S2: Adjust the final die hole size by adjusting the adjustment turntable, and stretch it into a blank with a corresponding cross-sectional area according to requirements; S3: The stretched blank will enter the primary extrusion device through the detection wheel, and the circular blank will be processed by the two-sided roller into a primary blank with flat front and rear sides.

[0017] S4: After the processing of the primary blank is completed, it will enter the secondary extrusion device, and through the four-sided roller, a square cross-section secondary blank will be processed by high-precision calendering and wire drawing; S5: After the processing of the secondary blank is completed, it will be bent and cut by the forming device to obtain the final spring washer.

[0018] Compared with the prior art, the present invention provides a spring washer forming device, which has the following beneficial effects: 1. In this spring washer forming device, through the setting of the shear rollers, when the stretching rollers are worn and the trigger module is triggered, at this time, because the blank becomes thicker, the amount of blank entering the primary extrusion device is more, and after being extruded, it will appear wider. At this time, the shear rollers are made to cross each other by the hydraulic cylinder, and the excess blank can be sheared to prevent the excess material from entering the secondary extrusion device, thus avoiding the backlog of materials at the secondary extrusion device and also avoiding the possibility of damage to the secondary extrusion device caused by excessive load at the secondary extrusion device.

[0019] 2. In this spring washer forming device, by making the detection synchronizing rod abut against the connecting rod at the minimum die hole, the detection wheel just abuts against the surface of the stretched blank. The movement of the blank will drive the detection wheel to rotate. When the blank becomes thicker, the trigger module will be triggered, and when the blank becomes thinner, the trigger module will also be triggered, so as to be able to timely remind the staff and realize the monitoring of the equipment. The stretching roller at the minimum die hole has relatively large wear and needs to be replaced in time to avoid affecting subsequent production.

[0020] 3. In this spring washer forming device, through two-stage extrusion and wire drawing processing, compared with one-stage processing, the load on the four-sided roller can be reduced, the risk of roller overload damage or fatigue damage can be reduced, and at the same time, the processing speed can also be improved.

[0021] 4. The spring washer forming device, through the setting of the stretching component, ensures that when the adjusting turntable rotates, the two adjusting sliders can move towards each other synchronously, so as to adjust the size of the film hole, enabling the stretching component to freely adjust the required blank cross-sectional size.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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.

[0025] Such as Figure 1-7As shown in the figure, it includes a rolling device 10, a primary extrusion device 20, a secondary extrusion device 30 and a forming device 40. These four devices are installed in sequence in the production workshop, and a guiding device is provided between every two adjacent devices for the positioning and conveying of the blank. The secondary extrusion device 30 is provided with four flat extrusion rollers, and a square through-hole is formed between the four flat extrusion rollers. When the iron bar passes through this through-hole, it can be extruded into a flat square iron bar. The forming device 40 is provided with a bending member and a cutting member. The bending member bends the iron bar into an open-type annular spring washer, and then the cutting is completed by the cutting member, and finally it can be formed. Among them, the steel material 50 is the blank forming process. The rolling device 10 includes a stretching assembly and a detection assembly. There are three stretching assemblies, and the detection assembly is arranged on one side close to the primary extrusion device 20. The stretching assembly includes an adjusting slider 101 and an adjusting screw rod 103. The adjusting screw rod 103 is rotatably connected to the rolling device 10. The adjusting slider 101 is slidably arranged in the rolling device 10, and the adjusting slider 101 slides relative to the adjusting screw rod 103. The external part of the adjusting slider 101 is provided with a stretching roller. Three adjusting cavities 11 and a sliding cavity 12 are opened in the rolling device 10. The adjusting slider 101 and the adjusting screw rod 103 are located in the adjusting cavity 11. An adjusting turntable 102 is fixed to the external part of the adjusting screw rod 103. Corresponding data is set on the adjusting turntable 102, which can be adjusted manually or connected to an intelligent device through gears for remote control. There are two adjusting sliders 101. The adjusting slider 101 is threadedly connected to the adjusting screw rod 103. The thread directions inside the two adjusting sliders 101 are opposite, which can ensure that when the adjusting turntable 102 rotates, the two adjusting sliders 101 can move synchronously towards each other to adjust the size of the film hole, so that the stretching assembly can freely adjust the required cross-sectional size of the blank. A connecting rod 1011 and a rolling wheel 1012 are also fixed to one side end face of the adjusting slider 101. The connecting rod 1011 penetrates through the sliding cavity 12 to the outside. The rolling wheel 1012 is detachably installed on the connecting rod 1011. The side end face of the connecting rod 1011 also extends to both sides, and its bottom abuts against the detection synchronizing rod 104.

[0026] The detection component includes a detection synchronization rod 104. The detection synchronization rod 104 slides within the rolling device 10 and is installed within the rolling device 10 through at least two synchronization springs 105. The synchronization springs 105 are in a tensile state. A detection mounting block 1041 is fixed to one side end face of the detection synchronization rod 104. The detection mounting block 1041 extends to the outside and slides within the rolling device 10. A bracket 1042 is movably connected within the detection mounting block 1041. The bracket 1042 is fixed to the detection mounting block 1041 through a detection spring 1045. A trigger module 1046 is fixed to the side end face of the detection mounting block 1041 away from the rolling device 10. A detection wheel 1044 is rotatably connected to the bottom of the bracket 1042. Contact blocks 1043 extend outward from both side end faces of the bracket 1042. The contact blocks 1043 are in contact with the trigger module 1046. A part of the trigger module 1046 extends downward. A contact inductor and a rotational speed sensor are provided within the trigger module 1046. The rotational speed sensor detects whether the detection wheel 1044 rotates, and the contact inductor detects whether the contact blocks 1043 are in contact. A buzzer or a warning light is also provided on the trigger module 1046. By making the detection synchronization rod 104 abut against the connecting rod 1011 at the minimum film hole, the detection wheel 1044 just abuts against the surface of the stretched blank. The movement of the blank will drive the detection wheel 1044 to rotate. When the blank becomes thicker, it will abut against the detection wheel 1044 and drive the bracket 1042 and the contact blocks 1043 to move upward, so that the contact blocks 1043 are disengaged from abutting against the trigger module 1046. At this time, the trigger module 1046 will be triggered. When the blank becomes thinner, due to the limitation of the contact blocks 1043, the detection wheel 1044 will be disengaged from abutting against the blank. At this time, the detection wheel 1044 cannot rotate, and thus the trigger module 1046 will also be triggered, enabling it to remind the staff that there is significant wear on the stretching roller at the minimum film hole and it needs to be replaced in a timely manner.

[0027] An installation box body 21 is provided on the primary extrusion device 20. The left and right sides of the installation box body 21 are hollow and penetrated. A first extrusion roller and a shearing roller are provided within the installation box body 21. Among them, the first extrusion roller is rotatably installed, and the shearing roller is movably installed. There are two first extrusion rollers, including extrusion rollers 212. Connecting gears 2121 are provided on both sides of the extrusion rollers 212. The connecting gears 2121 on the same side of the two extrusion rollers 212 are meshed with each other. The extrusion rollers 212 and the connecting gears 2121 are fixed together through a rotating shaft. A motor 214 is installed on the rotating shaft at the bottom of one of the extrusion rollers 212. Among them, four second extrusion rollers are provided within the secondary extrusion device 30, so that the blank is just extruded into a square shape. By performing the extrusion and wire drawing process in two steps, compared with a single processing, the load on the four-sided rollers can be reduced, the risk of roller overload damage or fatigue damage can be reduced, and at the same time, the processing speed can also be increased.

[0028] Two through tracks 22 are provided in the installation box body 21. The shearing roller includes a shearing roller 211 and a hydraulic cylinder 23. The shearing roller 211 slides in the track 22. The shearing roller 211 is power-connected to the first extrusion roller through a belt 213. The track 22 is arranged in an arc shape, and the center of the arc is the same as the center of the first extrusion roller. Two mounting posts 232 are fixed on the upper and lower end faces of the installation box body 21. A hydraulic cylinder 23 is movably installed on each mounting post 232. A hydraulic rod 231 is telescopically installed in the hydraulic cylinder 23. The hydraulic rod 231 is sleeved on the shearing roller 211. Two groups of shearing blades 2111 are arranged on the outer peripheral side of each shearing roller 211. The distance between the two groups of shearing blades 2111 on one side is the same as the width of the spring gasket, so that the required square blank can be exactly cut out. Through the setting of the shearing roller, when the stretching roller is worn and the trigger module 1046 is triggered, at this time, because the blank becomes thicker, the content of the blank entering the first-stage extrusion device 20 is more, and it will appear wider after being extruded. At this time, the shearing rollers are staggered by the hydraulic cylinder 23, and the redundant blank can be sheared to avoid the redundant material from entering the second-stage extrusion device 30, resulting in the accumulation of materials at the second-stage extrusion device 30, and also avoiding the possibility of damage to the second-stage extrusion device 30 caused by the excessive load at the second-stage extrusion device 30 due to the accumulation.

[0029] A usage method of a spring washer forming device is as follows: S1: Pass the blank (thick steel bar) through the die hole of the rolling device, that is, the hole between the two rolling wheels 1012, and force it to pass through under the extrusion of the pulling force and the pushing force, so that its cross-sectional area is reduced and its length is extended.

[0030] S2: Adjust the final die hole size by adjusting the adjusting turntable 102, and stretch it into a blank with a corresponding cross-sectional area according to the requirements; S3: The stretched blank will enter the first-stage extrusion device through the detection wheel 1044, and the circular blank is processed into a first-stage blank with flat front and rear sides by the two-sided roller.

[0031] S4: After the processing of the first-stage blank is completed, it enters the second-stage extrusion device, and through the four-sided roller, a square cross-sectional second-stage blank is processed by high-precision calendering and wire drawing; S5: After the processing of the second-stage blank is completed, it is bent and cut through the forming device to obtain the final spring washer.

[0032] Working principle: During use, place the processed blank through the film holes clamped by multiple rolling wheels 1012. Set the required cross-sectional size of the blank by adjusting the turntable 102. Stretch the blank multiple times until it reaches the set radius size. Then, the stretched blank will first enter the primary extrusion device 20 and be processed by the two-sided roller wheels into a state with flat front and rear sides. Then, it enters the secondary extrusion device 30 and is processed by the four-sided roller wheels to perform high-precision calendering and wire drawing to form a square state. Finally, it is completely cut by the forming equipment to complete the processing of the spring washer.

[0033] When adjusting the position of the rolling wheel 1012, the connecting rod 1011 on the side with the smallest film hole will abut against the detection synchronization rod 104. At this time, the detection synchronization rod 104 drives the detection wheel 1044 to be on the same horizontal line as the rolling wheel 1012 at the smallest film hole. Therefore, the blank after extrusion molding at the smallest film hole can just abut against the detection wheel 1044 and drive it to rotate. When the blank becomes thicker, it will abut against the detection wheel 1044 and drive the bracket 1042 and the contact block 1043 to move upward, so that the contact block 1043 disengages from the trigger module 1046. At this time, the trigger module 1046 will be triggered. When the blank becomes thinner, due to the restriction of the contact block 1043, the detection wheel 1044 will disengage from the blank. At this time, the detection wheel 1044 cannot rotate, and thus the trigger module 1046 will also be triggered, which is used to remind the staff to replace the worn rolling wheel 1012. If the staff fails to replace it in time and the equipment continues to operate, the trigger module 1046 triggered after becoming thicker will cause the hydraulic cylinder 23 to start. The hydraulic rod 231 pushes the shear rollers 211 to move inward simultaneously, so that the corresponding shear blades 2111 cooperate to form a shape similar to scissors. Then, due to the setting of the belt 213, the motor 214 can drive all the extrusion rollers 212 and shear rollers 211 to rotate simultaneously. The blank after becoming thicker will become wider through the extrusion of the extrusion rollers 212. Therefore, the rotation of the shear rollers 211 can shear the excess blank so that the blank will not affect the subsequent process.

[0034] In summary, for this spring washer forming equipment, through the setting of the shearing rollers, when the stretching rollers are worn and trigger the trigger module 1046, at this time, due to the thickening of the blank, the amount of blank entering the primary extrusion device 20 will be relatively large. After being extruded, it will show a wider phenomenon. At this time, the hydraulic cylinder 23 is used to make the shearing rollers cross each other, so as to shear the excess blank and prevent the excess material from entering the secondary extrusion device 30, thus avoiding the backlog of materials at the secondary extrusion device 30 and also avoiding the possibility of damage to the secondary extrusion device 30 caused by excessive load at the secondary extrusion device 30 due to the backlog; by detecting that the synchronization rod 104 abuts against the connecting rod 1011 at the minimum film hole, the detection wheel 1044 just abuts against the surface of the stretched blank. The movement of the blank will drive the detection wheel 1044 to rotate. When the blank thickens, the trigger module 1046 will be triggered. When the blank thins, the trigger module 1046 will also be triggered, so as to be able to timely remind the staff that there is significant wear on the stretching rollers at the minimum film hole and they need to be replaced in time to avoid affecting subsequent production; and through the two-stage extrusion and wire drawing process, compared with the one-stage process, it can reduce the load on the four-sided rollers, reduce the risk of roller overload damage or fatigue damage, and at the same time improve the processing speed; through the setting of the stretching assembly, it is ensured that when the adjustment turntable 102 rotates, the two adjustment sliders 101 can move synchronously towards each other to adjust the size of the film hole, so that the stretching assembly can freely adjust the required cross-sectional size of the blank.
