Description

Technical Field

[0001] This invention relates to the field of grinding technology, specifically a leveling and grinding device for cross-cutting shear processing. Background Technology

[0002] There are two main types of shearing for metal sheets: disc shears and cross shears. Disc shears are mainly used for longitudinal shearing, while cross shears are mainly used for transverse shearing with oblique blades, thereby cutting the metal strip to a suitable length for subsequent processing.

[0003] In cross-cutting shears, the force on the cutting edge is relatively concentrated during shearing. Therefore, the primary purpose of leveling and grinding cross-cutting shears is to process the beveled surface of the cutting edge. Currently, the main grinding method is linear grinding. During grinding, the beveled surface of the cross-cutting shear and the grinding wheel are tangential, and the contact point between the grinding wheel and the cross-cutting shear moves linearly during continuous grinding. Therefore, when a large protrusion is formed on the beveled surface, the force applied by the grinding wheel may be directly applied to the root of the protrusion. With a large grinding depth, this can easily damage the root of the protrusion, affecting the grinding quality.

[0004] In addition, currently, most existing leveling and grinding equipment uses constant power grinding, which results in uneven protrusion sizes and unstable instantaneous grinding amount, affecting the grinding quality. Summary of the Invention

[0005] The purpose of this invention is to provide a leveling and grinding device for cross-cutting shear processing, so as to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The leveling and grinding equipment is used to grind the cutting edge of cross scissors. The cross scissors are provided with several limiting grooves. The leveling and grinding equipment includes a machine body, a drive device, a clamping device, a cooling device, and a grinding wheel. The machine body is provided with a grinding chamber. The drive device is placed in the grinding chamber. The drive device and the grinding wheel are connected by a drive. The clamping device and the drive device are fastened together. The cooling device and the drive device are fastened together.

[0008] The drive unit includes a variable angle assembly, which includes a guide rail and a mounting base. The mounting base and the guide rail are slidably connected. The guide rail is arc-shaped. The mounting base is connected to the cross scissors drive via a clamping device.

[0009] The cross shear is provided with a blade for shearing and a plurality of limiting grooves for mounting and fixing, and the cross shear is polished by a leveling and grinding device. The machine body provides a working space through a grinding cavity, and a driving device serves as a main power source, which drives the polishing wheel to rotate to polish the blade and controls the movement of the cross shear. The cross shear is fixed by a clamping device to prevent misalignment, and the grinding area is cooled by a cooling device to prevent temperature rise from affecting the grinding accuracy. By providing an angle changing assembly, the moving direction of the cross shear is in an arc shape during grinding, that is, when the blade in a certain width interval is polished, the to-be-polished area rotates along the arc to form a virtual circle, the circle is a grinding path, the polishing wheel is inscribed in the grinding path, the angle between the outer circle of the polishing wheel and the grinding path is smaller than the angle between the polishing wheel and the tangent position, and during the grinding process, the blade is gradually ground from the outside to the inside to avoid directly grinding the inside of the protrusion, thereby improving the surface accuracy.

[0010] Further, the angle changing assembly further comprises a reversing motor and a guide wheel, the mounting seat is provided with a driving groove, the reversing motor is arranged in the driving groove, the shaft end of the reversing motor is provided with a gear, the guide rail is provided with a tooth surface, the gear is engaged with the tooth surface, the guide rail is provided with a plurality of guide ribs, the guide wheel is rotatably connected with the mounting seat, and the recess on the guide wheel is in frictional contact with the guide ribs.

[0011] The reversing motor is mounted by providing a driving groove, and the reversing motor is used to drive the gear to rotate, and the gear is used to engage with the tooth surface on the guide rail. Since the guide rail is arranged in an arc shape, the torque output by the reversing motor is used to drive the mounting seat to slide along the guide rail. The guide wheel is guided by being provided with a plurality of guide wheels, and the guide wheel is arranged in a concave shape to cooperate with the guide ribs to improve the guiding accuracy. During the driving process, the guide wheel can rotate along the guide ribs.

[0012] Further, the driving device further comprises a horizontal module, a driving motor and a bracket, the horizontal module is fixedly connected with the grinding cavity, the movable end of the horizontal module is fixedly connected with the guide rail, the bracket is fixedly connected with the grinding cavity, the driving motor is fixedly connected with the bracket, and the output end of the driving motor is fixedly connected with the polishing wheel.

[0013] The horizontal module is installed in the grinding cavity and is divided into a fixed end and a movable end. The fixed end is installed on the bottom surface of the grinding cavity, and the movable end can move linearly to drive the guide rail to slide. The blade in a width interval is polished in an arc motion. After the polishing at this position is completed, the guide rail is driven to move along the length direction of the blade to polish the blade in the next width interval. The bracket is fixed in the grinding cavity to mount the driving motor. The driving motor is used to output torque to drive the polishing wheel to rotate, so that the grinding surface of the polishing wheel linearly contacts the blade to ensure that the polishing wheel only rotates during the working process and facilitates the adjustment of the movement track of the blade.

[0014] Furthermore, the drive device also includes a speed regulating component, which includes a strain gauge and a conductive ring. One side of the strain gauge is fastened to the outer circular surface of the drive motor shaft end. The bracket is provided with an annular groove, and two contacts are respectively provided in the annular groove. There are two conductive rings, and the two conductive rings are respectively electrically connected to the two terminals of the detection power supply through the contacts. The inner rings of the two conductive rings are respectively fastened to both ends of the strain gauge.

[0015] Grinding efficiency is monitored by setting up a speed control component. A strain gauge is attached to the output of the drive motor to provide feedback on the load on the grinding edge. When the instantaneous grinding area increases, the micro-deformation of the strain gauge increases, i.e., the resistance increases. Two conductive rings are respectively fitted onto both ends of the strain gauge. Two contacts located within the ring grooves are used for electrical contact with the conductive rings. These two contacts are electrically connected to the two terminals of the detection power supply. During conduction, the contacts and the outer ring of the conductive rings slide together. The conductive rings and strain gauges use a detachable contact design, facilitating replacement when wear occurs and ensuring detection accuracy.

[0016] Furthermore, the strain gauge is electrically connected to the detection power supply via two conductive rings to form a speed control circuit, and the commutator motor is electrically connected to the speed control circuit.

[0017] The detection power supply is used to output the detection current of the rated voltage. When the resistance increases, the current of the speed regulation circuit decreases. The input current of the commutator motor and the current of the speed regulation circuit are positively correlated. The smaller the current of the speed regulation circuit, the smaller the input current of the commutator motor is through intelligent adjustment, which reduces the output torque of the commutator motor, thereby reducing the instantaneous rotation angle of the cross shears, that is, reducing the instantaneous grinding depth of the grinding wheel, and ensuring the grinding quality.

[0018] Furthermore, the clamping device includes a support base, one side of the mounting base is fastened to the support base, the support base is provided with a plurality of clamping cylinders, and the output end of the clamping cylinder is provided with a limiting post;

[0019] During grinding: The limiting post is inserted into the limiting groove of the horizontal shears.

[0020] The mounting base drives the support base to rotate. The clamping cylinder on the support base is used to output displacement, which drives the limit post to move and press the cross shears onto the surface of the support base, thus facilitating the rotation of the cross shears. By inserting the limit post into the limit groove of the cross shears, multi-directional limiting is achieved to ensure grinding accuracy.

[0021] As an optimization, the diameter of the limiting post is set to decrease gradually along the end away from the clamping cylinder. By setting the diameter of the limiting post in a gradual manner, it can be used to fix the limiting groove of different specifications. At the same time, the maximum diameter of the limiting post is greater than the diameter of the limiting groove, which provides auxiliary limiting in the thickness direction for the cross shears.

[0022] As an optimization, the cooling device includes a cooling pipe and a nozzle. The nozzle and the grinding chamber are securely connected, and the cooling pipe and the nozzle are connected by pipes. Coolant is introduced through the cooling pipe and then guided into the nozzle. The nozzle pressurizes the coolant and sprays it onto the contact area between the grinding wheel and the cutting edge for localized cooling. This temperature process affects the grinding and leveling accuracy.

[0023] As an optimization, a collection tank is provided on the machine body, located below the contact point between the grinding wheel and the blades of the cross-section shears. By setting up the collection tank, the coolant can be collected, making it easy to recycle and reducing energy consumption.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the variable angle component, the movement direction of the cross shears is in an arc shape during grinding. That is, when grinding the blade edge within a certain width range, the area to be ground rotates along the arc, forming a virtual circle. This circle is the grinding path. The grinding wheel and the grinding path are internally tangent, so that the angle between the outer circle of the grinding wheel and the grinding path is smaller than the angle between the grinding wheel and the tangent at this location. During the grinding process, grinding is gradually performed from the outside of the protruding edge to the inside, avoiding direct grinding of the inner side of the protrusion, thus improving surface accuracy. When the instantaneous grinding area increases, all the micro-deformations of the strain gauge increase, that is, the resistance increases. The detection power supply is used to output the detection current of the rated voltage. When the resistance increases, the current of the speed regulation circuit decreases. The input current of the commutating motor and the current of the speed regulation circuit are positively correlated. The smaller the current of the speed regulation circuit, the smaller the input current of the commutating motor is through intelligent adjustment, reducing the output torque of the commutating motor, thus reducing the instantaneous rotation angle of the cross shears, that is, reducing the instantaneous grinding depth of the grinding wheel, and ensuring grinding quality.

Detailed Implementation

[0033] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0034] Example: Figures 1-7 As shown, the present invention provides a technical solution for a leveling and grinding equipment for cross-cutting shear processing.

[0035] The leveling and grinding equipment is used to grind the cutting edge of cross scissors. The cross scissors are provided with several limiting grooves. The leveling and grinding equipment includes a machine body 1, a drive device 2, a clamping device 3, a cooling device 4, and a grinding wheel 5. The machine body 1 is provided with a grinding chamber 11. The drive device 2 is placed in the grinding chamber 11. The drive device 2 and the grinding wheel 5 are connected by transmission. The clamping device 3 and the drive device 2 are fastened together. The cooling device 4 and the drive device 2 are fastened together.

[0036] The drive device 2 includes a variable angle assembly 22, which includes a guide rail 221 and a mounting base 225. The mounting base 225 and the guide rail 221 are slidably connected. The guide rail 221 is arc-shaped. The mounting base 225 is connected to the cross scissors drive via a clamping device 3.

[0037] The cross-section shears are equipped with a cutting edge for shearing and multiple limiting grooves for installation and fixation. The cross-section shears are ground using a leveling and grinding device. The machine body 1 provides the working space through the grinding chamber 11. The drive device 2 serves as the main power source, driving the grinding wheel 5 to rotate and grind the cutting edge, and controlling the movement of the cross-section shears. The cross-section shears are fixed by a clamping device 3 to prevent misalignment, and the grinding area is cooled by a cooling device 4 to prevent temperature rise from affecting grinding accuracy. By incorporating a variable angle component 22, the cross-section shears move in an arc shape during grinding. That is, when grinding a certain width range of the cutting edge, the area to be ground rotates along the arc, forming a virtual circle. This circle is the grinding path. The grinding wheel 5 is internally tangent to the grinding path, ensuring that the angle between the outer circle of the grinding wheel 5 and the grinding path is smaller than the angle between the grinding wheel 5 and the tangent at this location. During grinding, the grinding gradually proceeds from the outside of the protruding cutting edge to the inside, avoiding direct grinding of the inner side of the protrusion and improving surface accuracy.

[0038] Furthermore, the angle-changing assembly 22 also includes a commutator motor 222 and a guide wheel 224. The mounting base 225 is provided with a drive groove 2251, the commutator motor 222 is placed in the drive groove 2251, the shaft end of the commutator motor 222 is provided with a gear 223, the guide rail 221 is provided with a toothed surface 2211, the gear 223 and the toothed surface 2211 mesh, the guide rail 221 is provided with a plurality of guide ribs 2212, the guide wheel 224 and the mounting base 225 are rotatably connected, and the groove on the guide wheel 224 and the guide ribs 2212 are in frictional contact.

[0039] The commutator motor 222 is installed by setting the drive slot 2251. The commutator motor 222 is used to drive the gear 223 to rotate. The gear 223 is used to mesh with the tooth surface 2211 on the guide rail 221. Since the guide rail 221 is arc-shaped, the torque output by the commutator motor 222 is used to drive the mounting base 225 to slide along the guide rail 221. Multiple guide wheels 224 are set for guidance. The guide wheels 224 are concave and are used to cooperate with the guide rib 2212 to improve the guidance accuracy. During the driving process, the guide wheels 224 can rotate along the guide rib 2212.

[0040] Furthermore, the drive device 2 also includes a horizontal module 21, a drive motor 23, and a bracket 24. The horizontal module 21 is fastened to the grinding chamber 11, the movable end of the horizontal module 21 is fastened to the guide rail 221, the bracket 24 is fastened to the grinding chamber 11, the drive motor 23 is fastened to the bracket 24, and the output end of the drive motor 23 is fastened to the grinding wheel 5.

[0041] The horizontal module 21 is installed inside the grinding chamber 11 and consists of a fixed end and a movable end. The fixed end is installed on the bottom surface of the grinding chamber 11, while the movable end can move linearly to drive the guide rail 221 to slide. Grinding is performed in an arc-shaped motion within a certain width range of the cutting edge. After grinding in one area, the guide rail 221 is moved along the length of the cutting edge to perform grinding in the next width range. The bracket 24 is fixed inside the grinding chamber 11 and is used to install the drive motor 23. The drive motor 23 outputs torque to rotate the grinding wheel 5, ensuring linear contact between the grinding surface of the grinding wheel 5 and the cutting edge. This guarantees that the grinding wheel 5 only rotates during operation, facilitating adjustment of the cutting edge's movement trajectory.

[0042] Furthermore, the drive device 2 also includes a speed regulating component 25, which includes a strain gauge 251 and a conductive ring 252. One side of the strain gauge 251 is fastened to the outer circular surface of the shaft end of the drive motor 23. The bracket 24 is provided with an annular groove 241, and two contacts are respectively provided in the annular groove 241. Two conductive rings 252 are provided, and the two conductive rings 252 are respectively electrically connected to the two terminals of the detection power supply through the contacts. The inner rings of the two conductive rings 252 are respectively fastened to both ends of the strain gauge 251.

[0043] The grinding efficiency is monitored by setting a speed control component 25. Strain gauge 251 is attached to the output end of the drive motor 23 to provide feedback on the load on the grinding edge. When the instantaneous grinding area increases, all the micro-deformations of the strain gauge 251 increase, i.e., the resistance increases. Two conductive rings 252 are respectively fitted onto both ends of the strain gauge 251. Two contacts located in the ring groove 241 are used to make contact with the conductive rings 252 for electrical conduction. The two contacts are electrically connected to the two terminals of the detection power supply. During conduction, the contacts and the outer ring of the conductive ring 252 are slidably connected. The conductive rings 252 and the strain gauge 251 have a detachable contact, which facilitates replacement when wear occurs, ensuring detection accuracy.

[0044] Furthermore, the strain gauge 251 is electrically connected to the detection power supply via two conductive rings 252 to form a speed control circuit, and the commutator motor 222 is electrically connected to the speed control circuit.

[0045] The detection power supply is used to output the detection current of the rated voltage. When the resistance increases, the current of the speed regulation circuit decreases. The input current of the commutator motor 222 and the current of the speed regulation circuit are positively correlated. The smaller the current of the speed regulation circuit, the smaller the input current of the commutator motor 222 is made through intelligent adjustment, thereby reducing the output torque of the commutator motor 222. This reduces the instantaneous rotation angle of the cross shears, that is, the instantaneous grinding depth of the grinding wheel 5 is reduced, thus ensuring the grinding quality.

[0046] Furthermore, the clamping device 3 includes a support base 31, one side of the mounting base 225 is fastened to the support base 31, the support base 31 is provided with a plurality of clamping cylinders 32, and the output end of the clamping cylinder 32 is provided with a limiting post 33.

[0047] During grinding: the limiting post 33 is inserted into the limiting groove of the horizontal shears.

[0048] The mounting base 225 drives the support base 31 to rotate. The clamping cylinder 32 on the support base 31 is used to output displacement and drive the limiting post 33 to move, pressing the cross shears onto the surface of the support base 31, thereby facilitating the rotation of the cross shears. By inserting the limiting post 33 into the limiting groove of the cross shears, multi-directional limiting is achieved to ensure grinding accuracy.

[0049] As an optimization, the diameter of the limiting post 33 is set to decrease along the end away from the clamping cylinder 32. By setting the diameter of the limiting post 33 in a gradual manner, it can be used to fix the limiting groove of different specifications. At the same time, the maximum diameter of the limiting post 33 is greater than the diameter of the limiting groove, which provides auxiliary limiting in the thickness direction for the cross shear.

[0050] As an optimization, the cooling device 4 includes a cooling pipe 41 and a nozzle 42. The nozzle 42 is fastened to the grinding chamber 11, and the cooling pipe 41 and the nozzle 42 are connected by pipes. Coolant is introduced through the cooling pipe 41 and then introduced into the nozzle 42. The nozzle 42 pressurizes the coolant and sprays it onto the contact area between the grinding wheel 5 and the cutting edge for localized cooling. This temperature process affects the grinding and leveling accuracy.

[0051] As an optimization, the machine body 1 is provided with a collection tank 12, which is located below the contact point between the grinding wheel 5 and the blades of the cross-section shears. By setting up the collection tank 12 to collect the coolant, it is easy to recycle and reduce energy consumption.

[0052] The working principle of this invention is as follows: By setting the variable angle component 22, the horizontal shear moves in an arc shape during grinding. That is, when grinding the blade edge within a certain width range, the area to be ground rotates along the arc, forming a virtual circle. This circle is the grinding path. The grinding wheel 5 is internally tangent to the grinding path, so that the angle between the outer circle of the grinding wheel 5 and the grinding path is smaller than the angle between the grinding wheel 5 and the tangent at this location. During the grinding process, grinding gradually proceeds from the outside of the protruding edge to the inside, avoiding direct grinding of the inner side of the protrusion, thus improving surface precision. When the instantaneous grinding area increases, all the micro-deformations of strain gauge 251 increase, that is, the resistance increases. The detection power supply is used to output the detection current of the rated voltage. When the resistance increases, the current of the speed regulation circuit decreases. The input current of the commutator motor 222 and the current of the speed regulation circuit are positively correlated. The smaller the current of the speed regulation circuit, the smaller the input current of the commutator motor 222 is made through intelligent adjustment, thereby reducing the output torque of the commutator motor 222. This reduces the instantaneous rotation angle of the cross shears, that is, the instantaneous grinding depth of the grinding wheel 5 is reduced, thus ensuring the grinding quality.

[0053] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
