[0028] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Embodiment: A steel springboard precision shearing auxiliary device, such as Figure 1-Figure 5As shown, it includes a mounting frame 1, a conveyor 2, a controller 3, a mold 4, a guide rod 5, a moving frame 6, a hydraulic cylinder 7, a shearing tool 8, a clamping assembly and a fixed length mechanism. The conveyor 2 is installed on the upper right side of the mounting frame 1. When the steel springboard is formed, it will be transported to the top surface of the conveyor 2, and the conveyor 2 will transport the formed steel springboard to the left. The mold 4 is connected to the upper left side of the mounting frame 1. The upper left side of the mounting frame 1 is symmetrically connected with guide rods 5. The number of guide rods 5 is two. A moving frame 6 is slidably connected between the two guide rods 5. The controller 3 is installed on the upper front side of the moving frame 6. The hydraulic cylinder 7 is installed on the upper part of the moving frame 6, and the hydraulic cylinder 7 is inclined at 60 degrees. The upper end of the hydraulic cylinder 7 is set There is an oil pipeline for an external oil storage device. The oil storage device and the oil pipeline can control the amount of hydraulic oil in the cylinder body of the hydraulic cylinder 7, so that the telescopic rod of the hydraulic cylinder 7 can be controlled to extend and retract. The shearing tool 8 is connected to the telescopic rod of the hydraulic cylinder 7. The shearing tool 8 is located on the left side of the mold 4. The shearing tool 8 and the mold 4 are both provided with positioning holes 9. The shape of the positioning hole 9 is consistent with the longitudinal cross-sectional shape of the steel springboard, and the bottom surface height of the positioning hole 9 is consistent with the top surface height of the conveyor 2, so that when the conveyor 2 transports the formed steel springboard to the left, the formed steel springboard can smoothly pass through the shearing tool 8 and the positioning holes 9 on the mold 4. The clamping assembly is used to clamp the steel springboard, and the fixed length mechanism is used to control the cutting length of the steel springboard.

[0030] like Figure 3 As shown, the clamping assembly includes a shunt pipe 11, a clamping block 12 and a return spring 13. The mold 4 has symmetrical front and rear receiving grooves 10, and the two receiving grooves 10 are respectively located at the front and rear sides of the positioning hole 9 on the mold 4. The shunt pipe 11 is connected to the upper part of the mold 4. The shunt pipe 11 is a three-way pipe. The upper end of the shunt pipe 11 is connected to the cylinder body of the hydraulic cylinder 7, and the other two ends of the shunt pipe 11 are respectively connected to the inside of the two receiving grooves 10. The receiving grooves 10 are slidably connected with clamping blocks 12. The number of clamping blocks 12 is two. The sides of the clamping blocks 12 on the front and rear sides that are close to each other slide through the side of the positioning hole 9 on the mold 4, and the sides of the clamping blocks 12 on the front and rear sides that are close to each other are respectively in the same vertical plane with the front and rear sides of the positioning hole 9 on the mold 4, so as not to affect the formed steel springboard passing through the positioning hole 9 on the mold 4. Return springs 13 are provided in the two receiving grooves 10, and the two ends of the return spring 13 are respectively connected to the clamping blocks 12 and the mold 4.

[0031] like Figure 4 and Figure 5As shown, the fixed length mechanism includes a sliding rod 14, a mounting plate 15, a distance sensor I 16 and a locking assembly. The sliding rod 14 is symmetrically slidably connected to the left side of the upper part of the mounting frame 1. The number of sliding rods 14 is two. A mounting plate 15 is connected between the left ends of the two sliding rods 14. The distance sensor I 16 is installed on the upper right side of the mounting plate 15. The locking assembly is used to lock the position of the sliding rod 14; the locking assembly includes a sliding locking rod 18 and a limiting block 19. Annular grooves 17 are evenly spaced on the sliding rod 14, and the annular grooves 17 are distributed from left to right. The sliding locking rod 18 is symmetrically slidably connected to the left side of the upper part of the mounting frame 1. The sliding direction of the sliding locking rod 18 is perpendicular to the sliding direction of the sliding rod 14. The lower end of the sliding locking rod 18 can be inserted into the annular groove 17 to lock the position of the sliding rod 14 and the mounting plate 15. The limiting block 19 is connected to the sliding locking rod 18, and the bottom surface of the limiting block 19 contacts the top surface of the mounting frame 1 to limit the sliding locking rod 18.

[0032] When it is necessary to shear the steel springboard, first install the device in the specified position, then pull the sliding lock rod 18 upwards, drive the limit block 19 to move upwards and disengage from the top surface of the mounting frame 1, then the lower end of the sliding lock rod 18 will separate from the annular groove 17, and then according to the length of the steel springboard that needs to be cut, pull the mounting plate 15 to the left, so that the position of the mounting plate 15 can be adjusted, and at the same time, the mounting plate 15 can drive the sliding rod 14 to move to the left. Since the distance between two adjacent annular grooves 17 is consistent, the distance that the mounting plate 15 is pulled out to the left can be known by observing how many annular grooves 17 are exposed from the left side of the mounting frame 1. When the mounting plate 15 moves to the specified position, push the sliding lock rod 18 downward to reset, which can drive the limit block 19 to move downward and reset to contact the top surface of the mounting frame 1 again. At this time, the lower end of the sliding lock rod 18 can be inserted into one of the annular grooves 17, so that the position of the sliding rod 14 and the mounting plate 15 can be adjusted. Lock; then the formed steel springboard is conveyed to the top surface of the conveyor 2 through the conveying equipment, and the controller 3 can control the conveyor 2 to convey the steel springboard to the left, so that the left end of the steel springboard passes through the positioning hole 9 on the mold 4 and the positioning hole 9 on the shearing tool 8 in turn, until the distance sensor Ⅰ16 detects that the left end of the steel springboard is flush with the right side of the mounting plate 15, the distance sensor Ⅰ16 will send a signal, and the controller 3 will control the conveying equipment and the conveyor 2 to stop working after receiving the signal, so that the steel springboard stops moving, and the controller 3 can control the oil storage device to convey the hydraulic oil to the cylinder body of the hydraulic cylinder 7, and the hydraulic oil in the cylinder body of the hydraulic cylinder 7 will first flow through the shunt pipe 11 to the receiving groove 10, and the hydraulic oil in the receiving groove 10 will squeeze the clamping blocks 12 on the front and rear sides to move to the side close to each other, and the reset spring 13 will be stretched so that the clamping blocks 12 on the front and rear sides can clamp the steel springboard to keep the steel springboard stable and facilitate the subsequent shearing of the steel springboard;When the accommodating groove 10 can no longer contain the hydraulic oil, the hydraulic oil in the cylinder body of the hydraulic cylinder 7 will gradually increase, causing the telescopic rod of the hydraulic cylinder 7 to extend, and the telescopic rod of the hydraulic cylinder 7 can drive the shearing tool 8 to move toward the rear and lower part. The shearing tool 8 cooperates with the mold 4 to shear the steel springboard, and the shearing distance only needs to be slightly greater than the thickness of the steel springboard to completely shear the steel springboard, thereby improving the shearing effect. The sheared steel springboard has no support from the conveyor 2, so the sheared steel springboard will directly fall down to the lower left side of the mounting frame 1 and be manually taken out for collection. At this time, the distance sensor Ⅰ16 detects that there is no steel springboard on the right side of the mounting plate 15, and the distance sensor Ⅰ16 will send a signal. After receiving the signal, the controller 3 will control the oil storage device to extract the hydraulic oil in the cylinder body of the hydraulic cylinder 7, thereby enabling the hydraulic The telescopic rod of the cylinder 7 is shortened, and the telescopic rod of the hydraulic cylinder 7 can drive the shearing tool 8 to move forward and upward to reset, so that the positioning hole 9 on the mold 4 and the positioning hole 9 on the shearing tool 8 are aligned horizontally, and the hydraulic oil in the receiving groove 10 will flow into the cylinder body of the hydraulic cylinder 7 along the shunt pipe 11, so that the reset spring 13 can be restored to its original state, which can drive the clamping blocks 12 on the front and rear sides to move away from each other, so that the clamping blocks 12 on the front and rear sides release the steel springboard, and then the controller 3 will control the conveying equipment and the conveyor 2 to continue working, so that the steel springboard can continue to be conveyed to the left, so that the remaining steel springboards can pass through the positioning holes 9 on the mold 4 and the positioning holes 9 on the shearing tool 8 in turn, until the distance sensor I 16 detects that the left end of the steel springboard is in contact with the right side of the mounting plate 15 again, and so on, the steel springboard can be automatically cut to a fixed length with precision. ;

[0033] When the existing shearing machine is in use, since the installation positions of the upper and lower blades are fixed, the spacing between the upper and lower blades is also relatively fixed, resulting in the spacing between the upper and lower blades being unable to be adjusted with the different thicknesses of the steel springboard. If the spacing between the upper and lower blades is too large, the steel springboard will be torn during the shearing process, resulting in an uneven shearing edge. If the spacing between the upper and lower blades is too small, the shearing force will increase, resulting in the steel springboard being squeezed and deformed during the shearing process, resulting in a poor shearing effect. Therefore, the mounting block 20, the distance sensor II 21, the clamping assembly and the adjustment assembly are designed;

[0034] like Figure 6 and Figure 7As shown, the steel springboard precision shearing auxiliary device also includes a mounting block 20, a distance sensor II 21, a clamping assembly and an adjusting assembly. The mounting block 20 is connected to the lower right side of the mold 4, the distance sensor II 21 is installed in the mounting block 20, the clamping assembly is used to clamp the top surface of the steel springboard, and the adjusting assembly is used to adjust the position of the shearing tool 8; the clamping assembly includes a fixed block 22, a lifting rod 23, a pressing plate 24, an inclined rod 2401 and a compression spring 25. The upper right side of the mold 4 is symmetrically connected to the fixed block 22, and the lifting rod 23 is slidably connected to the fixed block 2 2, the pressing plate 24 is connected to the lower end of the lifting rod 23, the inclined rod 2401 is connected to the right side of the pressing plate 24, the inclined rod 2401 is inclined and arranged with the left side lower and the right side higher, the compression spring 25 is wound around the outside of the lifting rod 23, and the two ends of the compression spring 25 are respectively connected to the fixed block 22 and the pressing plate 24; the adjustment component includes a driving motor I 26, a screw rod 27, a transmission component 28, a digital micrometer 29 and a fixed anvil 30, the upper left part of the front and rear sides of the mounting frame 1 is connected to the driving motor I 26, the upper left part of the mounting frame 1 is symmetrically rotated front and back and connected to the screw rod 27, the screw rod 28 is connected to the upper left part of the mounting frame 1, and the screw rod 28 is connected to the upper left part of the mounting frame 1. The rod 27 corresponds to the drive motor Ⅰ26 one by one, and the transmission assembly 28 is composed of a worm wheel and a worm. The worm wheel is connected to the left end of the screw 27, and the worm is connected to the output shaft of the drive motor Ⅰ26, and the worm wheel and the worm are meshed, so that the output shaft of the drive motor Ⅰ26 can drive the corresponding screw 27 to rotate through the transmission assembly 28, and the two screws 27 are threadedly connected to the moving frame 6. The scale frame of the digital micrometer 29 is installed on the upper rear part of the left side of the mold 4; the digital micrometer 29 of the present application has been slightly modified to fix the movable measuring anvil of the digital micrometer 29 On its scale frame, the movable anvil and the scale frame of the digital micrometer 29 are fixedly connected to the mold 4 without moving, and then the fixed anvil 30 of the digital micrometer 29 is fixedly connected to the inner side of the moving frame 6, so that the fixed anvil 30 of the digital micrometer 29 can move left and right with the moving frame 6. The detection principle of the digital micrometer 29 is to detect the distance between its movable anvil and the fixed anvil 30 (existing technology). This detection principle can be used to detect the moving distance of the moving frame 6, thereby controlling the distance between the shearing tool 8 and the mold 4.

[0035] When the conveyor 2 conveys the steel springboard to the left until it contacts the inclined rod 2401, the steel springboard will squeeze the inclined rod 2401 to move upward, driving the pressure plate 24 and the lifting rod 23 to move upward, and the compression spring 25 is compressed. Under the elastic force of the compression spring 25, the bottom surface of the pressure plate 24 can always press the top surface of the steel springboard, so that the bottom surface of the steel springboard can be close to the top surface of the conveyor 2. When the steel springboard moves to the left to below the distance sensor Ⅱ21, the distance sensor Ⅱ21 will detect the distance between it and the inner bottom surface of the steel springboard, and transmit the detection data to the controller 3. Since the distance between the distance sensor Ⅱ21 and the top surface of the conveyor 2 is constant, the controller 3 can obtain the thickness of the steel springboard by subtracting the distance between the distance sensor Ⅱ21 and the top surface of the conveyor 2 from the distance between the distance sensor Ⅱ21 and the inner bottom surface of the steel springboard. The controller 3 can calculate the distance between the shearing tool 8 and the mold 4 according to the thickness of the steel springboard through a formula. The preset value of the spacing between the shearing tool 8 and the mold 4 is set (the spacing between the shearing tool 8 and the mold 4 is usually about 1 / 20 of the thickness of the steel springboard, which is most appropriate). Then the controller 3 can control the driving motor I 26 and the transmission assembly 28 to drive the screw rod 27 to rotate forward and reversely. The forward and reverse rotation of the screw rod 27 can drive the moving frame 6 to move left and right. The moving frame 6 can drive the shearing tool 8 and the fixed anvil 30 of the digital micrometer 29 to move left and right. The digital micrometer 29 can detect the distance between its movable anvil and the fixed anvil 30 in real time, and the digital micrometer 29 can display its detected value through the screen. When the distance between the movable anvil of the digital micrometer 29 and its fixed anvil 30 is consistent with the preset value of the spacing between the shearing tool 8 and the mold 4 calculated by the controller 3, the controller 3 will control the driving motor I 26 to stop working, so that the spacing between the shearing tool 8 and the mold 4 can be automatically adjusted according to the different thicknesses of the steel springboard to ensure the shearing effect.

[0036] like Figure 8 and Fig. 9As shown, the steel springboard precision shearing auxiliary device also includes a rotating roller 31, a grinding belt 32 and a driving motor II 33. The two rotating rollers 31 are symmetrically rotated up and down and connected to the mounting plate 15. The grinding belt 32 is wound around the two rotating rollers 31, and the right side of the grinding belt 32 and the right side of the mounting plate 15 are located in the same vertical plane. The driving motor II 33 is connected to the upper front side of the mounting plate 15, and the front end of the rotating roller 31 on the upper side is connected to the output shaft of the driving motor II 33; when the distance sensor I 16 detects that the left end of the steel springboard is in contact with the right side of the grinding belt 32 (that is, the above-mentioned steel springboard is in contact with the left side of the grinding belt 32), the steel springboard is in contact with the right side of the grinding belt 32. When the left end of the springboard is flush with the right side of the mounting plate 15), the distance sensor I16 will send a signal. After receiving the signal, the controller 3 will control the drive motor II33 to drive the upper rotating roller 31 to rotate, thereby driving the grinding belt 32 and the lower rotating roller 31 to rotate. The rotation of the grinding belt 32 can grind the left end of the steel springboard, thereby automatically removing the burrs on the left end of the steel springboard. When the distance sensor I16 detects that there is no steel springboard on the right side of the mounting plate 15, the distance sensor I16 will send a signal. After receiving the signal, the controller 3 will control the drive motor II33 to stop working.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
