Description

Technical Field

[0001] The present application relates to the technical field of shearing of metal plates, and in particular to a shearing machine for mechanical processing. Background Art

[0002] A shearing machine is a machine that uses one blade to make reciprocating linear motion relative to another blade to shear plates. By using a moving upper blade and a fixed lower blade and a reasonable blade gap, shearing force is applied to metal plates of various thicknesses to break and separate the plates into the required size.

[0003] Since the shearing machine is used to shear metal plates, the tool wears greatly. During the shearing process, the large shearing force may cause the blade to curl. The shearing machine in the prior art cannot sharpen the tool in time after shearing. Therefore, if the unsharpened tool continues to shear with a curled blade, the cut of the plate will be uneven and the plate will be distorted, seriously affecting the shearing quality of the plate. If the tool with a curled blade continues to work, the probability of chipping will increase, resulting in the tool being scrapped, thereby reducing the tool's service life and increasing operating costs. In addition, the chipped tool may continue to be used without knowing it, thereby increasing the unqualified rate of sheared plates.

[0004] For this reason, we propose a shearing machine for mechanical processing to solve the above problems. Summary of the invention

[0017] Compared with the prior art, the advantages of this application are:

[0018] (1) By setting a shearing plate assembly, the output end of the hydraulic cylinder contracts, driving the top plate, the pressure plate, the tool holder and the upper tool to descend. The top plate descends so that the telescopic rod 1 and the spring 1 are compressed. Under the elastic force of the spring 1, the pressure plate presses the plate. After the plate is pressed, the output end of the hydraulic cylinder continues to contract, driving the top plate to continue to descend, thereby driving the tool holder and the upper tool to continue to descend and shear the plate together with the lower tool. When not working, the upper tool is located above the pressure plate. Therefore, when the pressure plate descends, it first contacts the plate to press the plate. After the plate is pressed, the upper tool shears, thereby achieving pressing first and then shearing, making the plate more stable during shearing and having better shearing quality.

[0019] (2) By setting a grinding assembly, the tool holder drives the grinding assembly on the tool holder to descend synchronously in the process of driving the upper tool to descend. The upper tool descends and contacts the grinding assembly on the inclined plate. The grinding assembly on the tool holder descends and contacts the lower tool fixedly installed on the workbench. The upper tool and the lower tool contact and squeeze the transverse grinding block at the same time. After the transverse grinding block is squeezed, it drives the installation bar to move. The movement and squeezing of the installation bar causes the telescopic rod 2 and the spring 2 to be compressed. Under the elastic action of the spring 2, the transverse grinding block is tightly attached to the upper tool and the lower tool. The installation bar continues to move until the installation bar squeezes the control The control switch is squeezed and closed, and the electromagnetic block is energized. After the electromagnetic block is energized, it attracts the permanent magnet block to drive the push block and the longitudinal grinding block to move in the direction of the tool, until the longitudinal grinding block fits with the upper tool and the lower tool. The motor starts to energize and work, and the motor drives the turntable and the slide column to rotate. Under the constraint of the slide column and the slip ring, the connecting rod and the slide bar are driven to reciprocate left and right, thereby driving the transverse grinding block and the longitudinal grinding block to reciprocate left and right to repeatedly grind the cutting edges of the upper tool and the lower tool, so that the cutting edges of the upper tool and the lower tool can be automatically polished after each shearing.

[0020] (3) By setting up the detection component, when the tool holder drives the upper tool and the grinding component on it to descend, the upper tool and the lower tool will also be squeezed with the detection component. The upper tool and the lower tool squeeze the ball, the mounting block and the rubber column. The rubber column will be compressed after being squeezed. When the motor drives the slide bar to reciprocate left and right, it will also drive the detection component to reciprocate left and right, so that the ball rolls on the cutting edge of the upper tool and the lower tool. When the cutting edge is chipped, when the ball rolls to the position of the chipped edge, the ball enters the notch of the chipped edge under the elastic action of the rubber column. At this time, the elasticity of the rubber column is released, and the pressure sensed by the pressure sensor is reduced. Therefore, when chipping occurs, the pressure value detected by the pressure sensor will fluctuate significantly. The pressure sensor will feed back the collected data to the controller, thereby sounding an alarm to remind the staff to replace the tool, thereby ensuring the quality of shearing.

[0021] (4) By setting a plurality of evenly distributed telescopic rods 2 and springs 2, the plurality of telescopic rods 2 and springs 2 are respectively set under a plurality of transverse grinding blocks, so that the elastic force of the springs 2 can act on the transverse grinding blocks, thereby achieving a better grinding effect.

[0022] (5) By setting an electromagnetic block and a permanent magnet block to drive the longitudinal grinding block to move after the tool and the transverse grinding block are pressed tightly, the longitudinal grinding block moves and presses on the sides of the upper and lower tools after the upper and lower tools and the transverse grinding block are pressed tightly. This can avoid interference between the tools during the descent process, and can better wrap the tool edge for grinding, resulting in a better grinding effect. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. Example

[0035] The present invention provides a shearing machine for mechanical processing, please refer to Figure 1-4 A shearing machine for mechanical processing comprises a workbench 1, a mounting frame 2 fixedly connected to the workbench 1, an upper tool 3 and a lower tool 4 fixedly connected to the rear side of the workbench 1 by bolts, a shearing assembly 5 is arranged on the mounting frame 2, the shearing assembly 5 comprises a hydraulic cylinder 501, a top plate 502, a telescopic rod 503, a spring 504, a pressure plate 505 and a tool holder 506; the hydraulic cylinder 501 is fixedly connected to both ends of the workbench 1, the top plate 502 is fixedly connected to the output end of the hydraulic cylinder 501, a plurality of telescopic rods 503 and a spring 504 are provided and are evenly distributed, the spring 504 is sleeved on the outside of the telescopic rod 503, the telescopic rod 503 and the spring 504 are fixedly connected between the top plate 502 and the pressure plate 505, the tool holder 506 is fixedly connected to the top plate 502, and the upper tool 3 is fixedly connected to the tool holder 506 by bolts.

[0036] Specifically, the output end of the hydraulic cylinder 501 contracts, driving the top plate 502, the pressure plate 505, the tool holder 506 and the upper tool 3 to descend. The descent of the top plate 502 compresses the telescopic rod 503 and the spring 504, and the pressure plate 505 presses the plate under the elastic force of the spring 504. After the plate is pressed, the output end of the hydraulic cylinder 501 continues to contract, driving the top plate 502 to continue to descend, thereby driving the tool holder 506 and the upper tool 3 to continue to descend and shear the plate together with the lower tool 4. When not working, the upper tool 3 is located above the pressure plate 505. Therefore, when the pressure plate 505 descends, it first contacts the plate to press the plate, and after the plate is pressed, the upper tool 3 shears, thereby realizing pressing the material first and then shearing, making the plate more stable during shearing and having better shearing quality.

[0038] There are multiple telescopic rods 711 and springs 712 that are evenly distributed. The springs 712 are sleeved on the outside of the telescopic rods 711. The telescopic rods 711 and springs 712 are fixedly connected between the inner bottom wall of the slide bar 706 and the mounting bar 709. A control switch 713 is provided inside the slide bar 706. The multiple telescopic rods 711 and springs 712 are respectively arranged under the multiple transverse grinding blocks 710, so that the elastic force of the springs 712 can act on the transverse grinding blocks 710, so that the grinding effect is better.

[0039] The sliding hole 714 is opened on the side of the mounting strip 709, and the sliding rod 715 is slidably connected to the sliding hole 714. An electromagnetic block is arranged inside the sliding hole 714. One end of the sliding rod 715 located inside the sliding hole 714 is fixedly connected with a permanent magnet block. The magnetism of the electromagnetic block when energized is opposite to that of the permanent magnet block. The control switch 713 controls the opening and closing of the electromagnet and the motor 702. The pushing block 716 is fixedly connected to the other end of the sliding rod 715. The longitudinal grinding block 717 is fixedly connected to the pushing block 716. The pushing plate 718 is fixedly connected to the side of the pushing block 716 away from the longitudinal grinding block 717. The spring three 719 is fixedly connected between the pushing plate 718 and the mounting strip 709. The longitudinal grinding block 717 is moved and pressed against the side of the upper and lower cutting tools 4 after the upper and lower cutting tools 4 are pressed against the transverse grinding block 710. This can avoid interference between the cutting tools during the descent process, and can better wrap the cutting tool edge for grinding, so that the grinding effect is better.

[0040] Specifically, the tool holder 506 drives the grinding assembly 7 on the tool holder 506 to descend synchronously in the process of driving the upper tool 3 to descend, the upper tool 3 descends and contacts the grinding assembly 7 on the inclined plate 6, the grinding assembly 7 on the tool holder 506 descends and contacts the lower tool 4 fixedly installed on the workbench 1, the upper tool 3 and the lower tool 4 simultaneously contact and squeeze the transverse grinding block 710, and the transverse grinding block 710 drives the installation bar 709 to move after being squeezed, and the installation bar 709 moves and squeezes so that the telescopic rod 2 711 and the spring 2 712 are compressed, and under the elastic action of the spring 2 712, the transverse grinding block 710 is tightly attached to the upper tool 3 and the lower tool 4, and the installation bar 709 continues to move until the installation bar 709 squeezes the control switch 7 13. The control switch 713 is squeezed and closed, and the electromagnetic block is energized. After the electromagnetic block is energized, it attracts the permanent magnet block to drive the push block 716 and the longitudinal grinding block 717 to move in the direction of the tool, until the longitudinal grinding block 717 is in contact with the upper tool 3 and the lower tool 4. Then, the motor 702 starts to be energized and drives the turntable 701 and the slide column 703 to rotate. Under the constraint of the slide column 703 and the slip ring 704, the connecting rod 705 and the slide bar 706 are driven to reciprocate left and right, thereby driving the transverse grinding block 710 and the longitudinal grinding block 717 to reciprocate left and right to repeatedly grind the cutting edges of the upper tool 3 and the lower tool 4, so that the cutting edges of the upper tool 3 and the lower tool 4 can be automatically grinded after each shearing.

[0041] See also Figure 6 and Fig. 9 , multiple detection components 8 are evenly distributed on the mounting strip 709, and the detection component 8 includes a detection box 801, a pressure sensor 802, a bearing plate 803, a rubber column 804, a mounting block 805, and a ball 806; the detection box 801 is fixedly connected to the mounting strip 709, the pressure sensor 802 is fixedly connected to the inner bottom of the detection box 801, the bearing plate 803 is slidably connected to the inside of the detection box 801 and contacts with the pressure sensor 802, the rubber column 804 is fixedly connected to the bearing plate 803, and the upper end of the rubber column 804 passes through the detection box 801 and extends to the outside of the detection box 801, the mounting block 805 is fixedly connected to the upper end of the rubber column 804, and the ball 806 is rotatably connected to the mounting block 805.

[0042] Specifically, when the tool holder 506 drives the upper tool 3 and the grinding assembly 7 thereon to descend, the upper tool 3 and the lower tool 4 will also be squeezed with the detection assembly 8, and the upper tool 3 and the lower tool 4 squeeze the ball 806, the mounting block 805 and the rubber column 804. The rubber column 804 will be compressed after being squeezed. When the motor 702 drives the slide bar 706 to reciprocate left and right, it will also drive the detection assembly 8 to reciprocate left and right, so that the ball 806 rolls on the cutting edge of the upper tool 3 and the lower tool 4. When the cutting edge is broken, when the ball 806 rolls to the position of the broken edge, the ball 806 enters the notch of the broken edge under the elastic action of the rubber column 804. At this time, the elasticity of the rubber column 804 is released, and the pressure sensed by the pressure sensor 802 is reduced. Therefore, when the broken edge occurs, the pressure value detected by the pressure sensor 802 will fluctuate significantly. The pressure sensor 802 feeds back the collected data to the controller, thereby issuing an alarm (this is a prior art and will not be elaborated on in detail), reminding the staff to replace the tool, thereby ensuring the quality of the shearing.

[0043] Working principle: When shearing, the plate to be sheared is extended to the bottom of the pressing plate 505, and then the hydraulic cylinder 501 is started. The output end of the hydraulic cylinder 501 contracts, driving the top plate 502, the pressing plate 505, the tool holder 506 and the upper tool 3 to descend. The top plate 502 descends so that the telescopic rod 1 503 and the spring 1 504 are compressed. Under the elastic force of the spring 1 504, the pressing plate 505 presses the plate. After the plate is pressed, the output end of the hydraulic cylinder 501 continues to contract and drives the top plate 502 to continue to descend, thereby driving the tool holder 506 and the upper tool 3 to continue to descend and shear the plate together with the lower tool 4. When not working, the upper tool 3 is located above the pressing plate 505. Therefore, when the pressing plate 505 descends, it first contacts with the plate to press the plate. After the plate is pressed, the upper tool 3 shears, thereby realizing pressing the material first and then shearing, which makes the plate more stable when shearing and has better shearing quality.

[0044] After shearing, the hydraulic cylinder 501 continues to work, and the output end of the hydraulic cylinder 501 continues to contract, driving the tool holder 506 and the upper tool 3 to continue to descend. In the process of driving the upper tool 3 to descend, the tool holder 506 drives the grinding assembly 7 on the tool holder 506 to descend synchronously until the upper tool 3 descends and contacts the grinding assembly 7 on the inclined plate 6. The grinding assembly 7 on the tool holder 506 descends and contacts the lower tool 4 fixedly installed on the workbench 1. The upper tool 3 and the lower tool 4 are simultaneously in contact with and squeezed by the transverse grinding block 710. After the transverse grinding block 710 is squeezed, it drives the mounting bar 709 to move. The mounting bar 709 moves and squeezes so that the telescopic rod 2 711 and the spring 2 712 are compressed. Under the elastic action of the spring 2 712, the transverse grinding block 710 is tightly attached to the upper tool 3 and the lower tool 4. 709 continues to move until the installation bar 709 squeezes the control switch 713, and the control switch 713 is closed after being squeezed, and the electromagnetic block is energized. After the electromagnetic block is energized, it attracts the permanent magnet block to drive the push block 716 and the longitudinal grinding block 717 to move in the direction of the tool, until the longitudinal grinding block 717 is in contact with the upper tool 3 and the lower tool 4, and the motor 702 starts to be energized to work, and the motor 702 drives the turntable 701 and the slide column 703 to rotate. Under the constraint of the slide column 703 and the slip ring 704, the connecting rod 705 and the slide bar 706 are driven to reciprocate left and right, thereby driving the transverse grinding block 710 and the longitudinal grinding block 717 to reciprocate left and right to repeatedly grind the cutting edges of the upper tool 3 and the lower tool 4, so that the cutting edges of the upper tool 3 and the lower tool 4 can be automatically polished after each shearing.

[0045] When the tool holder 506 drives the upper tool 3 and the grinding assembly 7 thereon to descend, the upper tool 3 and the lower tool 4 will also be squeezed with the detection assembly 8, and the upper tool 3 and the lower tool 4 squeeze the ball 806, the mounting block 805 and the rubber column 804. The rubber column 804 will be compressed after being squeezed. When the motor 702 drives the slide bar 706 to reciprocate left and right, it will also drive the detection assembly 8 to reciprocate left and right, so that the ball 806 rolls on the cutting edge of the upper tool 3 and the lower tool 4. When the cutting edge is broken, when the ball 806 rolls to the position of the broken edge, the ball 806 enters the notch of the broken edge under the elastic action of the rubber column 804. At this time, the elasticity of the rubber column 804 is released, and the pressure sensed by the pressure sensor 802 is reduced. Therefore, when the broken edge occurs, the pressure value detected by the pressure sensor 802 will fluctuate significantly. The pressure sensor 802 feeds back the collected data to the controller, thereby sounding an alarm to remind the staff to replace the tool, thereby ensuring the quality of the shearing.

[0046] After grinding and testing are completed, the telescopic end of the hydraulic cylinder 501 extends, driving the tool holder 506, the upper tool 3 and the grinding assembly 7 thereon to move up and reset. During the resetting process, the mounting bar 709 leaves the control switch 713, and the electromagnetic block and the motor 702 are powered off. The electromagnetic block is powered off, so that the longitudinal grinding block 717 is reset to leave the upper tool 3 and the lower tool 4 under the elastic action of the spring three 719. The motor 702 is powered off and stops working, and the transverse grinding block 710 and the longitudinal grinding block 717 stop reciprocating motion. The grinding work is completed, and the telescopic end of the hydraulic cylinder 501 continues to extend, driving the pressure plate 505 to leave the plate, releasing the fixation of the plate, so as to continue the next cycle of shearing work.

[0047] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and its improved conception, which should be covered by the protection scope of the present application.
