Description

Technical Field

[0001] The present invention relates to the technical field of steel plate shearing, and more particularly to a continuous shearing device for steel plates. Background Art

[0002] Continuous steel plate shearing devices are widely used in the field of steel plate shearing. Continuous steel plate shearing greatly improves the efficiency of steel plate shearing. A continuous steel plate shearing device is an automatic machine suitable for processing large quantities of steel plates, primarily used for shearing. The equipment includes a feeder, a main body, a shearing head, a fixture, a temperature control device, and other components. The fixture and shearing device are particularly important.

[0003] When the existing continuous steel plate shearing device is in operation, the feeding device sends the steel plate to the fixing device, and then the fixing device fixes the steel plate, and then the next shearing action is carried out. At the same time, there is a temperature rise problem in the shearing process, and water sprinkling or spraying is used to cool down to complete the shearing process. However, the above shearing method still has some shortcomings: 1. The distance between the two rollers of the fixing device is fixed or adjusted by the thread. During the steel plate shearing process, the thickness of the steel plate may change, and it is necessary to stop the machine to adjust the fixing device to adapt to the change in steel plate thickness, thereby affecting work efficiency and output; 2. The cooling device during shearing performs a cooling process on the shearing position, and the flow direction of water cannot be accurately controlled, thereby causing some unnecessary waste. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a continuous shearing device for steel plates to solve the problems existing in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: a continuous shearing device for steel plates, comprising a main frame, a feed roller is provided in the middle of the main frame, a transmission mechanism is fixedly connected to the side of the main frame, a shearing head is provided on the top of the main frame, the side of the transmission mechanism is transmission-connected to the shearing head, the shearing head comprises a short side and a long side, blades are fixedly installed on the side of the short side, lower spring bases are provided on both sides of the middle of the long side, and a support spring is fixedly installed on the long side through the lower spring base thereon, an upper spring base is fixedly installed on the upper end of the support spring, and the upper end of the upper spring base is fixedly connected to an internal storage A guide hole is provided on the bottom side of the fixing block of the groove, a threaded rod is movably connected to the guide hole, the upper end of the threaded rod is fixedly connected to the sponge bottom plate, and a sponge is provided on the top of the sponge bottom plate, the bottom surface of the groove inside the fixing block is fixedly connected to a dial that can rotate around the guide hole, the side surface of the dial is fixedly connected to a paddle, the center of the dial is provided with a threaded hole, the side surface of the fixing block is fixedly connected to a guide slider, the inner side surface of the shearing head is provided with a guide groove, the rear end surface of the fixing block is provided with a limiting groove, a driving rod is movably connected in the limiting groove, and the limiting groove and the driving rod are fixedly connected to a return spring; Furthermore, there are 11 feed rollers arranged transversely.

[0006] Furthermore, the fixing blocks are arranged at the upper ends of the long sides of the shearing blades and are evenly arranged around the shearing blades. The upper end surfaces of the fixing blocks are fixedly connected with rubber gaskets.

[0007] Furthermore, the lower spring base, the support spring and the upper spring base at the bottom end of the fixed block cooperate with each other and are distributed at both ends of the bottom end of the fixed block.

[0008] Furthermore, the guide slide blocks are located on both sides of the fixed block, and the guide slide blocks cooperate with the guide grooves on the shearing cutter head. The guide grooves are distributed around the inner wall of the fixed block.

[0009] Furthermore, the threaded rod cooperates with a threaded hole opened in the middle of the dial, the dial is located on both sides of the bottom of the fixed block, and paddles are evenly distributed on the side of the dial, and the paddles interact with the bottom end of the rod.

[0010] Furthermore, the limiting grooves are distributed on both sides of the interior of the fixed block, and the limiting grooves and the shifting rod cooperate with each other through a return spring.

[0011] The technical effects and advantages of the present invention are as follows: 1. This invention provides a notched rubber gasket on the contact surface between the fixed block and the steel plate. The rubber gasket contacts the upper surface of the steel plate. The fixed block secures the steel plate through the combined force of the support spring and the feed roller. Furthermore, the fixed block with the rubber gasket does not cause indentations on the steel plate surface. The notched rubber gasket allows water squeezed out of the sponge during shearing to flow along the notch toward the blade, saving water required for cooling during shearing.

[0012] 2. This invention incorporates a support spring between the fixed block and the shearing head. Under the action of the support spring, the guide slides on either side of the fixed block can move along the guide grooves inside the shearing head. This facilitates adaptation to varying steel plate thicknesses, reduces the debugging time required for changes in steel plate thickness, and improves machine efficiency.

[0013] 3. This invention utilizes a sponge movement mechanism within a groove within the fixed block. The sponge is filled with water required for cooling. During operation, a lever within a limit groove on the inner side of the fixed block, driven by a limit spring, reciprocates. Each movement causes the dial to rotate a fixed amount, which in turn causes the threaded rod to push the sponge outward. Each shearing action causes the sponge to move outward, interacting with the steel plate to squeeze out some of the water until most of the sponge protrudes. This indicates that the cooling water within the sponge has been exhausted, facilitating clear and intuitive observation of the remaining water level in the device and allowing for timely replenishment.

The upper end of the threaded rod 409 is fixedly connected to a sponge base plate 407, and a sponge 408 is provided on the top of the sponge base plate 407. A dial 405 that can rotate around the guide hole 413 is fixedly connected to the bottom surface of the internal groove of the fixed block 404, and a paddle 406 is fixedly connected to the side of the dial 405. A threaded hole 414 is provided in the center of the dial 405, and a guide slider 416 is fixedly connected to the side of the fixed block 404. A guide groove 415 is provided on the inner side of the shearing head 4, and a limiting groove 417 is provided on the rear end surface of the fixed block 404. A shift rod 411 is movably connected in the limiting groove 417, and a return spring 418 is fixedly connected to the limiting groove 417 and the shift rod 411. Reference Figure 2 There are 11 feed rollers 2 arranged horizontally to transport the steel plate toward the shear head.

[0025] Reference Figure 4 The fixed block 404 is set at the upper end of the long side 4b of the shearing head 4 and is evenly arranged around the shearing head 4. The upper end surface of the fixed block 404 is fixedly connected to a rubber gasket 410. When working, the rubber gasket contacts the steel plate and fixes the steel plate.

[0026] Reference Figure 4 The lower spring base 401, the support spring 402 and the upper spring base 403 at the bottom of the fixed block 404 cooperate with each other and are distributed at both ends of the bottom of the fixed block 404, and move back and forth under the action of the spring to adapt to steel plates of different thicknesses.

[0027] Reference Figure 3 and Figure 5 The guide sliders 416 are located on both sides of the fixed block 404 , and the guide sliders 416 cooperate with the guide grooves 415 on the shearing head 4 , and the guide grooves 415 are distributed around the inner wall of the fixed block 404 .

[0028] Reference Figure 8 The threaded rod 409 cooperates with the threaded hole 414 opened in the middle of the dial 405. The dial 405 is located on both sides of the bottom of the fixed block 404. The dial 405 has paddles 406 evenly distributed on the side, and the paddles 406 interact with the bottom end of the lever 411.

[0029] Reference Figure 7 The limiting grooves 417 are distributed on both sides of the fixing block 404 , and the limiting grooves 417 and the shifting rod 411 cooperate with each other through the return spring 418 .

[0030] The present invention provides a rubber gasket with a notch on the contact surface between the fixed block and the steel plate. The rubber gasket contacts the upper surface of the steel plate. The fixed block fixes the steel plate through the combined action of the force of the support spring on the fixed block and the feed roller. The fixed block with the rubber gasket will not cause indentations on the surface of the steel plate. Through the rubber gasket with the notch, water squeezed out of the sponge during shearing flows along the notch toward the blade, which is beneficial to saving cooling water required during shearing.

[0031] The present invention provides a support spring between the fixed block and the shearing head. Under the action of the support spring, the fixed block can move along the guide groove inside the shearing head on the guide sliders located on both sides of the fixed block, which is conducive to adapting to different steel plate thicknesses, reducing the debugging time required for changes in steel plate thickness, and improving machine working efficiency.

[0032] The present invention provides a sponge movement mechanism in the internal groove of the fixed block, and the sponge is filled with water required for cooling. During operation, the dial rod in the limit groove on the inner side of the fixed block can reciprocate under the action of the limit spring. Each movement drives the dial to rotate quantitatively, thereby causing the threaded rod to push the sponge outward. Each time the sponge is sheared, it moves outward and acts with the steel plate to squeeze out part of the water therein until most of the sponge protrudes. At this time, it indicates that the water used for cooling in the sponge has been exhausted, which is conducive to intuitively and clearly observing the remaining water amount of the equipment and replenishing it in time.

[0033] The working principle of the present invention is as follows: the feed roller provided in the middle of the main frame rotates to move the steel plate toward the shearing head. When the steel plate is transported to the vicinity of the shearing head, the rubber gasket on the upper end of the fixed block contacts the steel plate, causing the guide sliders on both sides of the fixed block to move upward along the guide groove inside the shearing head. Under the action of the supporting spring, the steel plate is pressed by the feed roller and the rubber gasket. The feed roller and the shearing head rotate to perform the next shearing action, thereby preventing the steel plate from being damaged and wasted due to deviation and warping caused by the shearing action. The end face of the lever on the shearing head first contacts the steel plate, causing the lever to move along the limit slot. This compresses the return spring connected to the lever, pushing the paddle on the side of the dial through the bottom end of the lever, causing the dial to rotate, which in turn drives the threaded rod toward the steel plate, causing the sponge base to push the sponge out a certain distance. The compression between the sponge and the steel plate squeezes out water from the sponge, which flows toward the blade through the notch in the rubber gasket near the blade, thereby reducing the temperature during the shearing process. After the shearing action is completed, the lever is returned to its original position along the limit slot under the action of the spring's elastic force.
