Description

Technical Field

[0001] The invention relates to the field of metal wire straightening processing, in particular to a spring steel wire straightener. Background Art

[0002] Spring steel wire is a metal wire used to make springs. It has the characteristics of high strength and high toughness, and also has excellent elasticity, corrosion resistance and load capacity. Before the spring is made, the spring steel wire is first straightened with a straightener to change the shape of the material through mechanical force to make it straight.

[0003] Existing straighteners are mainly divided into roller straighteners and fully automatic straighteners. The cost of roller straighteners is lower than that of fully automatic straighteners, and they are suitable for many small processing plants. However, it is difficult for small processing plants to receive large-volume orders. They usually increase the number of orders to make profits, and it is easy to process multiple orders a day. However, the specifications of the wires required to be processed for each order are usually different, so it is necessary to frequently adjust the distance between multiple straightening rollers, or to replace straightening rollers of different specifications. However, the adjustment of roller straighteners usually requires workers to operate two rows of straightening rollers separately, and then detect the accuracy of the adjustment during the debugging stage. When the adjustment of the straightening rollers is not accurate enough, it is necessary to continue to fine-tune the straightening rollers manually. This method relies more on the experience of workers. It takes more time to adjust the straightening rollers each time, which affects the speed of the next order to be put into processing, and the efficiency is relatively low. The fully automatic straightener has a high degree of automation, which can reduce manual operation, making it better suitable for scenarios where different specifications of steel wires need to be processed frequently. However, this type of equipment is expensive and large in size, and is not suitable for many small processing plants.

[0004] Therefore, a spring wire straightener is proposed. Summary of the invention

[0005] The object of the present invention is to provide a spring steel wire straightener, which solves the problem that in the existing roller straightener, when the straightening roller needs to be adjusted frequently, the adjustment speed is slow due to manual adjustment, thus affecting the processing efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A spring steel wire straightener comprises a base, a shell, an observation window, a feeding device, a discharging device, a mounting frame and a straightening roller, wherein the shell is arranged on the base, the feeding device and the discharging device are respectively fixed at two ends of the base, and the two mounting frames are fixed on the base, and further comprises a measuring component, a transmission component and an adjusting component, wherein the measuring component is arranged on the mounting frame, the adjusting component is arranged on the base and is located on a side of the measuring component close to the discharging device, the transmission component is arranged between the measuring component and the adjusting component and connects the two, a plurality of the straightening rollers are arranged on the adjusting component, the measuring component measures the spring steel wire fed through the feeding device and transmits power to the adjusting component through the transmission component, the adjusting component adaptively adjusts the distance between the plurality of the straightening rollers to a state of clamping the steel wire according to the measurement data of the steel wire by the measuring component, and the straightened spring steel wire is sent out of the equipment through the discharging device.

[0008] It is known that the existing roller straighteners require manual operation when adjusting the straightening rollers, and the speed of adjustment depends on the proficiency of the workers. In small processing plants with a large number of small and medium-sized orders, the straightening rollers need to be adjusted frequently. If workers are required to adjust them, it will inevitably slow down the production rhythm and affect the factory's production efficiency. Therefore, this solution links the measuring component with the adjusting component, so that the adjusting component can perform synchronous adaptive adjustment according to the diameter measured by the measuring component for the spring steel wire when the spring steel wire enters the measuring component, so that it can have a faster adjustment speed than manual operation, effectively speeding up the production rhythm and improving processing efficiency.

[0009] Since steel wires of different diameters are often processed in small processing plants, it is known that greater force is required to deform thicker steel wires, so the straightening rollers need to be able to provide corresponding pressure when facing steel wires of different diameters.

[0010] Preferably, the measuring assembly includes two measuring clamps and spring 1, a sliding roller, a limit clamp, a connecting shaft, a limit block and spring 2 which are arranged opposite to each other in the vertical direction. The measuring clamp is arranged between the two mounting frames and is at the same horizontal height as the feed port of the feeding device. The two spring 1s are arranged between the two measuring clamps and the two ends of the spring 1 are respectively fixed to the two measuring clamps. The multiple sliding rollers are respectively fixed to the two ends of the measuring clamps. The measuring clamps are slidably connected to the limit clamps through sliding rollers. The connecting shaft is fixed to the side of the limit clamp away from the measuring clamp. The limit clamp is slidably connected to the mounting frame through the connecting shaft. The limit block is slidably connected inside the mounting frame and fixed to one end of the connecting shaft away from the limit clamp. The spring 2 is arranged inside the mounting frame and the two ends of the spring 2 are respectively connected to the side of the limit block away from the connecting shaft and the mounting frame.

[0011] In the above scheme, the upper and lower measuring clamps are matched with the limit clamps on both sides to realize the equidistant movement of the two measuring clamps in the vertical direction. When the spring steel wire enters between the two measuring clamps, the upper and lower measuring clamps can be moved respectively by a distance of the steel wire radius, thereby avoiding the phenomenon that the upper and lower measuring clamps move at different distances and cause inaccurate measurement results. In addition, in order to provide different pressures for steel wires of different diameters, spring one is arranged between the two measuring clamps. When the steel wire stretches the upper and lower measuring clamps apart, spring one will also be stretched. The stretching or compression degree of spring one will provide corresponding force to the measuring clamps. At this time, the measuring clamp controls the adjustment component to adjust the spacing between the two rows of straightening rollers and thus provide corresponding straightening pressure to the steel wire. When the diameter of the steel wire is larger, the pressure provided will be correspondingly enhanced, thereby achieving better clamping and straightening effects.

[0012] Preferably, the measuring clamp includes a front end and a rear end, the side of the measuring clamp close to the feeding device is the front end, and the side of the measuring clamp away from the feeding device is the rear end, and the front ends of the two measuring clamps are inclined relative to the rear ends in a direction away from the opposite measuring clamp.

[0013] In order to prevent the steel wire from being blocked by the closed measuring clamps when entering the measuring clamps, the shape of the measuring clamps needs to be limited accordingly. Through the above scheme, the front end of the measuring clamp is tilted to present a horizontally placed funnel shape, and the larger end of the funnel is facing the side of the feeding device. This can reduce the resistance of the steel wire entering between the two measuring clamps, so that the steel wire can more conveniently enter the rear end of the measuring clamp for measurement.

[0014] In order to prevent the iron filings and other impurities on the surface of the spring steel wire from affecting the straightening effect and to prevent the iron filings and other impurities from wearing the surface of the straightening roller, the surface of the steel wire needs to be simply cleaned before the steel wire enters the straightening roller for straightening.

[0015] Preferably, the surface of the rear end is coated with flannel with fine fluff, and the rear end is an arc-shaped structure with high ends and a recessed middle.

[0016] In the above scheme, when the steel wire passes through the front end and the rear end of the measuring clamp, the velvet coating at the rear end of the measuring clamp can remove impurities such as iron filings on the surface of the steel wire, thereby preventing impurities such as iron filings from moving with the steel wire to the straightening roller and causing wear on the surface of the straightening roller, thereby effectively improving the service life of the straightening roller. On the other hand, it can also reduce the abrasions and scratches on the surface of the steel wire caused by impurities such as iron filings adhering to the steel wire and then being squeezed by the straightening roller, thereby effectively reducing the defective rate.

[0017] Preferably, a groove is provided on the base, the groove is located in the vertical direction of the transmission assembly, the middle part is square in shape and penetrates the base, and the groove is arranged as a strip groove toward the direction of the feeding device and the discharging device, and the above-mentioned strip groove is inclined from high to low toward the middle by the feeding device and the discharging device on both sides.

[0018] It is known that after the steel wire enters the measuring clamp, the connecting frame will move toward the base. In the above scheme, a groove penetrating the base is provided to leave a moving position for the connecting frame. On the other hand, inclined strip grooves are provided on both sides of the groove facing the feeding device and the discharging device, which can collect impurities such as iron filings falling from the measuring clamp and iron filings generated during the straightening process of the steel wire by the straightening roller, and slide along the strip groove to the slotted discharge device that penetrates the base in the middle.

[0019] Preferably, the transmission assembly includes a fixed block, a connecting frame and a three-hole hinged rod, the fixed block is connected to the measuring clamp located at the lower side of the two measuring clamps, the connecting frame is fixedly connected to the lower side of the fixed block, one end of the three-hole hinged rod is hingedly connected to the lower end of the connecting frame, the hinge hole of the three-hole hinged rod close to one end of the connecting frame is a long waist hole, mounting blocks are provided on both sides of the groove on the base, the hinge hole in the middle part of the three-hole hinged rod is hingedly connected to the mounting block, and the height of the end of the connecting frame away from the fixed block in the vertical direction is lower than the height of the mounting block.

[0020] Because when the steel wire enters between the two measuring clamps, the measuring clamp at the bottom drives the adjusting assembly to be adjusted through the transmission assembly, a labor-saving structure is required. Through the above scheme, the length of the connecting frame is greater than the three-hole hinged rod to form a labor-saving lever, which can more easily drive the adjusting assembly and improve the adjustment efficiency of the equipment.

[0021] Preferably, the three-hole hinged rod uses the hinged hole in the middle as a dividing point, and one side close to the adjustment component is an arc structure, and the center of the arc structure is arranged on one side of the three-hole hinged rod close to the discharging device.

[0022] Due to the need to form a force-saving lever, the length of the articulated rod between the mounting block and the adjusting assembly is relatively short. If a conventional straight-line articulated rod is used, when the active adjusting block moves toward the direction of the feeding device, the articulated rod and the active adjusting block are likely to interfere with each other and affect the adjustment. Therefore, in the above scheme, the side of the three-hole articulated rod close to the adjusting assembly is set to be arc-shaped, so that it will not affect the movement of the adjusting assembly and thus affect the adjustment effect during transmission.

[0023] Preferably, the adjusting assembly is connected with a hinge block near one end of the three-hole hinge rod, the hinge block is hinged with the three-hole hinge rod, the hinge hole of the hinge block is a long waist hole, the adjusting assembly comprises an active adjusting block, a passive adjusting block, a mounting plate, a driving motor and an auxiliary sliding rod, the active adjusting block is connected with the hinge block, the passive adjusting block is slidably connected to the active adjusting block, the base is provided with a plurality of slide slots 1 and slide slots 2, the passive adjusting block is slidably connected to the slide slot 1, the mounting plate is fixedly connected to the passive adjusting block, the plurality of straightening rollers are arranged on the mounting plate and are connected through a pulley, the driving motor is arranged on the lower side of the mounting plate, the plurality of auxiliary sliding rods are fixedly connected to the lower side of the mounting plate and are arranged close to the driving motor, a connecting plate is fixedly connected between the plurality of auxiliary sliding rods under each of the mounting plates, the connecting plate is arranged below the driving motor, and the auxiliary sliding rod is slidably connected to the slide slot 2.

[0024] Through the above scheme, the active adjustment block adaptively moves according to the measurement of the steel wire by the two measuring clamps, thereby affecting the passive adjustment block slidably connected to the active adjustment block, and then adjusting the distance between the two rows of straightening rollers to a suitable distance, so that the device can adaptively adjust the straightening rollers to a suitable position according to the diameter of the steel wire; the surfaces on which the active adjustment block and the passive adjustment block contact each other are both made of smooth materials, which reduces the friction when the two move against each other, thereby reducing the resistance during adjustment.

[0025] Preferably, a locking handwheel is provided on one side of the passive adjustment block, a locking groove is provided on the surface of the active adjustment block on the side with the locking handwheel, and the surface in the locking groove that matches the locking handwheel is made of friction material.

[0026] Through the above scheme, the locking groove is embedded in the active adjustment block, and the characteristics of its surface material are opposite to those of the active adjustment block. It is a friction material with a higher friction coefficient. After the adjustment is completed, the user turns the locking handwheel to make it fit together with the locking groove and applies a certain pressure to it to increase the friction force, so that the active adjustment block and the passive adjustment block are locked under the action of friction force, preventing the straightening roller from deviating from the original position during the straightening process, thereby ensuring the straightening effect.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention solves the problem that in the existing roller straightener, when the straightening roller needs to be adjusted frequently, the adjustment speed is slow due to manual adjustment, which affects the processing efficiency. Specifically, by setting the three parts of the measuring component, the transmission component and the adjustment component to cooperate with each other, on the one hand, the adjustment component can be adaptively adjusted to a suitable position according to the measurement data of the measuring component, avoiding the instability caused by the influence of workers' experience on manual operation, simplifying the equipment operation steps and improving the use efficiency; on the other hand, a linked mechanical structure is adopted to replace the high-cost intelligent components in the fully automatic straightener, so that it can meet the production needs of small processing plants while controlling its cost.

[0029] 2. By providing a flannel coating on the surface of the measuring clamp and strip grooves on the base, on the one hand, the surface of the spring steel wire can be cleaned before entering the straightening roller, and on the other hand, impurities such as iron filings can be prevented from wearing the surface of the straightening roller as the steel wire moves to the straightening roller, which can effectively increase the service life of the straightening roller. It can also reduce the situation where impurities such as iron filings adhere to the steel wire and are squeezed by the straightening roller, causing abrasions and scratches on the surface of the steel wire caused by impurities such as iron filings, thereby effectively reducing the defective rate.

[0030] 3. By setting the spring 1 between the two measuring clamps, when the steel wire enters between the two measuring clamps, the measuring clamps will be stretched, and the spring 1 will also be stretched. The stretching or compression degree of the spring 1 will provide corresponding force to the measuring clamps. On the one hand, the measuring clamps are tightly attached to the steel wire, ensuring more accurate measurement results. On the other hand, the spacing between the two rows of straightening rollers is adjusted by controlling the adjustment component through the measuring clamp, thereby providing corresponding straightening pressure to the steel wire. When the diameter of the steel wire is larger, the pressure provided will be correspondingly enhanced, thereby achieving a better straightening effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 9 The present invention provides a spring steel wire straightener, and the technical solution is as follows:

[0043] For details, please refer to Figure 1 , Figure 2 and Figure 3A spring steel wire straightener comprises a base 1, a shell 2, an observation window 3, a feeding device 4, a discharging device 5, a mounting frame 6 and a straightening roller 7. The shell 2 is arranged on the base 1, and the observation window 3 is arranged on the top of the shell 2. The main part of the observation window 3 is made of a transparent PC board. The staff can observe and monitor the internal working process through the transparent observation window 3 when the equipment is running. The feeding device 4 and the discharging device 5 are respectively fixed at both ends of the base 1. The feeding device 4 and the discharging device 5 use a pinch roller structure to pinch and send the spring steel wire in and out. When in use, it is necessary to adjust the pressure of the pinch rollers in the feeding device 4 and the discharging device 5 according to different specifications of steel wires, so that it can pinch and send the steel wire more stably. The two The mounting frame 6 is fixed on the base 1, and a slideway for mounting the measuring component 8 is provided in the mounting frame 6, and the measuring component 8, a transmission component 9 and an adjustment component 10 are also provided. The measuring component 8 is arranged on the mounting frame 6, and the adjustment component 10 is arranged on the base 1 and is located on the side of the measuring component 8 close to the discharging device 5. The transmission component 9 is arranged between the measuring component 8 and the adjustment component 10 and connects the two. A plurality of straightening rollers 7 are arranged on the adjustment component 10. The measuring component 8 measures the spring steel wire fed through the feeding device 4. The measuring component 8 includes two measuring clamps 801 and a spring 1 802, a sliding roller 803, a limit clamp 804, a connecting shaft 805, a limit block 806 and a spring 2 80 7. The measuring clamp 801 includes a front end a and a rear end b. The side of the measuring clamp 801 close to the feeding device 4 is the front end a, and the side of the measuring clamp 801 away from the feeding device 4 is the rear end b. The rear end b is an arc-shaped structure with high ends and a sunken middle. The front ends a of the two measuring clamps 801 are inclined relative to the rear end b in a direction away from the opposite measuring clamp 801, presenting a horizontally placed funnel shape, and the larger end of the funnel shape faces the side of the feeding device 4. This arrangement can reduce the resistance of the steel wire entering between the two measuring clamps 801, so that the steel wire can more conveniently enter the rear end b of the measuring clamp 801 for measurement. In addition, in order to prevent impurities such as iron filings attached to the surface of the spring steel wire from affecting the straightening effect, and to avoid iron filings, etc. Impurities cause wear on the surface of the straightening roller 7. Before the steel wire enters the straightening roller 7 for straightening, the surface of the steel wire needs to be simply cleaned. Therefore, a flannel coating with fine fluff is used on the surface of the rear end b. When the steel wire passes through the front end a of the measuring clamp 801 and the rear end b, the flannel coating at the rear end b of the measuring clamp 801 can remove impurities such as iron filings on the surface of the steel wire, thereby preventing impurities such as iron filings from moving with the steel wire to the straightening roller 7 and causing wear on the surface of the straightening roller 7. The service life of the straightening roller 7 can be effectively improved. On the other hand, it can also reduce the situation where impurities such as iron filings adhere to the steel wire and are then squeezed by the straightening roller 7, causing abrasions and scratches on the surface of the steel wire caused by impurities such as iron filings, thereby effectively reducing the defective rate.

[0044] The measuring clamp 801 is arranged between the two mounting frames 6 and is at the same horizontal height as the feeding port of the feeding device 4. Since different degrees of force are required for deformation of steel wires of different thicknesses, the straightening roller 7 is required to provide corresponding pressure when facing steel wires of different diameters. Therefore, two springs 802 are respectively arranged between the two measuring clamps 801, and the two ends of the spring 802 are respectively fixedly connected to the two measuring clamps 801. When the spring steel wire stretches the upper and lower measuring clamps 801, the spring 802 will also be stretched. The degree of stretching or compression of the spring 802 will provide corresponding force to the measuring clamp 801. At this time, the measuring clamp 801 controls the adjustment component 10 to adjust the spacing between the two rows of straightening rollers 7 and thus provide corresponding straightening pressure to the steel wire. When the diameter of the steel wire is larger, the pressure provided will be correspondingly enhanced, thereby achieving better clamping and straightening effects; multiple sliding rollers 803 are respectively fixed at the two ends of the measuring clamp 801, and the limit clamp 804 is provided with a sliding rail capable of accommodating the sliding roller 803. The sliding roller 803 is slidably connected to the limit clamp 804, and the upper and lower measuring clamps 801 are matched with the limit clamps 804 on both sides to realize the equal distance movement of the two measuring clamps 801 in the vertical direction. When the spring steel wire enters between the two measuring clamps 801, the upper and lower measuring clamps 801 can be moved by a wire radius respectively, so as to avoid the phenomenon that the upper and lower measuring clamps 801 move different distances and cause inaccurate measurement results. The connecting shaft 805 is fixed on the limit clamp 804 away from the measuring clamp 801. On the other hand, the limit clamp 804 is slidably connected to the mounting frame 6 through the connecting shaft 805, the limit block 806 is slidably connected inside the mounting frame 6 and fixed at the end of the connecting shaft 805 away from the limit clamp 804, the spring 807 is arranged inside the mounting frame 6 and the two ends of the spring 807 are respectively connected to the side of the limit block 806 away from the connecting shaft 805 and the mounting frame 6. When the steel wire enters between the measuring clamps 801, the upper and lower measuring clamps 801 will be stretched open. At this time, the limit clamp 804 moves toward the mounting frames 6 on both sides.

[0045] As an embodiment of the present invention, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7The base 1 is provided with a groove 11, which is located in the vertical direction of the transmission assembly 9, and the middle part is square in shape and penetrates the base 1. The groove 11 is arranged in a strip-shaped groove toward the direction of the feeding device 4 and the discharging device 5. The strip-shaped groove is arranged from high to low inclining from the feeding device 4 and the discharging device 5 on both sides toward the middle. In this way, while leaving a moving position for the transmission assembly 9, the inclined strip-shaped grooves extending from both sides are arranged to collect and discharge impurities such as iron filings dropped during the straightening process. The transmission assembly 9 is connected to the measuring assembly 8 and the adjusting assembly 10 respectively, and the transmission assembly 9 includes a fixed block 901, a connecting frame 902 and a three-hole hinged rod 903. The fixed block 901 is connected to the measuring clamp 801 located at the lower side of the two measuring clamps 801. The connecting frame 902 is fixedly connected to the lower side of the fixed block 901. One end of the three-hole hinged rod 903 is hingedly connected to the lower end of the connecting frame 902. The hinge hole of the three-hole hinged rod 903 near one end of the connecting frame 902 is a long waist hole. The length of the connecting frame 902 is greater than the three-hole hinge. The length of the connecting rod 903 further forms a labor-saving lever, which makes it easier to drive the adjustment component 10, thereby improving the adjustment efficiency of the equipment. Since a labor-saving lever needs to be formed, the length of the hinged rod between the mounting block 14 and the adjustment component 10 is relatively short. If a conventional straight-line hinged rod is used, when the active adjustment block 1001 moves toward the direction of the feeding device 4, it is easy for the hinged rod and the active adjustment block 1001 to interfere with each other, thereby affecting the adjustment. The adjustment component 10 is connected to one end of the three-hole hinged rod 903. There is an articulated block 15, which is articulated with a three-hole articulated rod 903. The articulated hole of the articulated block 15 is a long waist hole. The other end of the three-hole articulated rod 903 is hingedly connected to the articulated block 15. The three-hole articulated rod 903 uses the articulated hole in the middle as a dividing point, and one side close to the articulated block 15 is an arc structure. The center of the arc structure is set on one side of the three-hole articulated rod 903 close to the discharge device 5. This arrangement ensures that the adjustment component 10 will not be blocked by the three-hole articulated rod 903 when it is close to it, thereby affecting the adjustment effect. The base 1 is provided with mounting blocks 14 on both sides of the groove 11, the hinge hole in the middle of the three-hole hinged rod 903 is hingedly connected to the mounting block 14, and the height of the end of the connecting frame 902 away from the fixed block 901 in the vertical direction is lower than the height of the mounting block 14. When the connecting frame 902 descends due to the expansion of the measuring clamp 801, the active adjustment block 1001 can be controlled to move toward the direction close to the connecting frame 902 through the three-hole hinged rod 903.

[0046] As an embodiment of the present invention, refer to Figure 7 , Figure 8 and Fig. 9The adjusting component 10 adaptively adjusts the distance between the plurality of straightening rollers 7 to a state of clamping the steel wire according to the measurement data of the steel wire by the measuring component 8, thereby avoiding the instability caused by the influence of the workers' experience in manual operation, simplifying the equipment operation steps, improving the use efficiency, and improving the problem of low manual adjustment efficiency. The adjusting component 10 includes an active adjusting block 1001, a passive adjusting block 1002, a mounting plate 1003, a driving motor 1004 and an auxiliary sliding rod 1005. The active adjusting block 1001 is connected to the hinge block 15, and the passive adjusting block 10 02 is slidably connected to the active adjustment block 1001. The surfaces of the active adjustment block 1001 and the passive adjustment block 1002 in contact with each other are made of smooth materials, which reduces the friction when the two move against each other, thereby reducing the resistance during adjustment. The base 1 is provided with a plurality of slide grooves 12 and slide grooves 2 13. The passive adjustment block 1002 is slidably connected to the slide groove 12. The mounting plate 1003 is fixedly connected to the passive adjustment block 1002. The active adjustment block 1001 performs adaptive movement according to the measurement of the steel wire by the two measuring clamps 801, thereby affecting the sliding connection in the active adjustment. The passive adjustment block 1002 on the block 1001 adjusts the distance between the two rows of straightening rollers 7 to a suitable distance, so that the device can adaptively adjust the straightening rollers 7 to a suitable position according to the diameter of the steel wire. A plurality of straightening rollers 7 are arranged on the mounting plate 1003 and connected through a pulley. The driving motor 1004 is arranged on the lower side of the mounting plate 1003. A driving motor 1004 is arranged under each of the two rows of straightening rollers 7. When the driving motor 1004 drives one of the straightening rollers 7 to rotate, the other straightening rollers 7 will obtain power through the pulley. 1005 is fixed on the lower side of the mounting plate 1003 and is arranged close to the drive motor 1004. The auxiliary slide bar 1005 is slidably connected to the slide groove 13. A connecting plate 1006 is fixedly connected between the multiple auxiliary slide bars 1005 under each of the mounting plates 1003. The connecting plate 1006 can serve as a reinforcing rib for the two auxiliary slide bars 1005. In addition, the connecting plate 1006 is arranged under the drive motor 1004, so that the connecting plate 1006 can not only improve the stability of the auxiliary slide bar 1005, but also support the drive motor 1004.

[0047] A locking handwheel 1007 is provided on one side of the passive adjustment block 1002, and a locking groove 1008 is provided on the surface of the active adjustment block 1001 on the side of the locking handwheel 1007. The locking groove 1008 is embedded in the active adjustment block 1001, and the characteristics of its surface material are opposite to those of the active adjustment block 1001, and it is a friction material with a higher friction coefficient. After the adjustment is completed, the user turns the locking handwheel 1007 to fit it together with the locking groove 1008 and applies a certain pressure to it to increase the friction force, so that the active adjustment block 1001 and the passive adjustment block 1002 are locked under the action of friction, preventing the straightening roller 7 from deviating from the original position during the straightening process, thereby ensuring the straightening effect.

[0048] The specific working principle is as follows: first, the staff needs to pass the front end of the spring steel wire that needs to be straightened through the feeding device 4, and then extend it between the two measuring clamps 801. At this time, the spring steel wire will open the upper and lower measuring clamps 801. Under the action of spring 1 802, the two measuring clamps 801 are tightly attached to the surface of the spring steel wire. At the same time, the measuring clamp 801 on the lower side moves downward while driving the connecting frame 902 to move downward, and drives the active adjustment block 1001 to move in the direction of the connecting frame 902 through the three-hole hinge rod 903. Since the passive adjustment block 1002 can only move in the direction perpendicular to the spring steel wire in the slide groove 12, when the active adjustment block 1001 moves toward the connecting frame 902, the passive adjustment block 1002 will move in the direction away from the moving path of the spring steel wire. And adaptive adjustment is performed according to the data measured by the measuring clamp 801. When the adjustment is completed, the staff turns the locking handwheel 1007 to make it cooperate with the locking groove 1008 to fix the passive adjustment block 1002 and the active adjustment block 1001. When the locking is completed, the staff starts the equipment, so that the feeding device 4 and the discharging device 5 start to convey the spring steel wire, and the driving motor 1004 starts to run to drive the straightening roller 7 to start straightening the passing spring steel wire. When the spring steel wire is straightened and conveyed out of the equipment through the discharging device 5, the staff will control the equipment to stop working and reversely turn the locking handwheel 1007 to unlock it. At this time, under the action of spring one 802 and spring two 807, the measuring clamp 801, the active adjustment block 1001 and the passive adjustment block 1002 are reset.
