Description

Technical Field

[0001] The invention relates to the field of circular shearing machines, and in particular to a pressing device for circular shearing machines. Background Art

[0002] A circular shear is a device used to shear irregularly shaped steel and iron sheets. The existing Chinese patent (CN101474692B) hydraulic circular steel shearing machine uses hydraulic power as the power to shear the material. It is fast and has low noise during the processing process, and is simple to realize material unloading. No metal debris will be generated during the shearing process. It is suitable for harsh environments. However, the device does not make any description on the fixing and pressing of the material during the circular shearing process. Since the materials for circular shearing are generally steel and iron sheets, both have a certain deformation ability, and during the circular shearing process, the fixing and pressing of the material is the prerequisite for ensuring the smooth circular shearing of the material. The existing pressing method cannot achieve equal pressure processing, and cannot achieve adaptive pressure on materials of different thicknesses, resulting in excessive force on the material being crushed, or insufficient force, and a large shaking amplitude during the circular shearing process, or even direct falling off, posing a great threat to the safety of workers. At the same time, the existing equipment cannot pre-flatten the material when shearing, and cannot deburr its edge after the circular shearing is completed, which increases the subsequent processing work of the workers.

[0037] Working principle: When the iron sheet and steel are cut into circles, since the iron sheet and steel to be cut are generally regular squares with a large area, the iron sheet or steel to be cut is first placed on the second pressure plate 2013, and part of the material is placed on the limit plate 307 and the receiving plate 306 at the same time to ensure that the cutter 507 can smoothly cut the material into circles. After the placement is completed, since the material itself has a certain gravity, in the initial state, the initial data of the first dynamometer 205 and the second dynamometer 209 are recorded by the central control system, and the initial data is used as the zero point. At this time, the second dynamometer 209 produces data changes under the action of the material gravity, that is, Under the action of material gravity, the second pressure plate 2013, the receiving plate 306 and the limiting plate 307 move downward synchronously, and then the second pressure plate 2013 moves the second electric shaft 2012 and the fixed plate 2011 downward, and the limiting block 2010 limits the fixed plate 2011, so that the second electric shaft 2012 and the fixed plate 2011 slide down with the limiting block 2010 as the sliding track, ensuring that the fixed plate 2011 can move downward vertically. While the fixed plate 2011 moves downward, the pull ring of the second dynamometer 209 is pulled synchronously, so that the second dynamometer 209 produces data changes, and the central control system records the data and temporarily records it as B.

[0038] Then the cylinder 201 is controlled to start working, and the first electric shaft 202 and the first L-shaped plate 301 are driven to move downward by the cylinder 201, and then the fixed disc 203 is driven to move downward by the first electric shaft 202, and then the sponge 204 and the first dynamometer 205 are driven to move downward by the fixed disc 203, and then the first pressure plate 207 is driven to move downward by the sponge 204, and the first pressure plate 207 drives the two first limit rods 206 and the connecting rod 208 to move downward. After a pressure plate 207 contacts the upper surface of the material, the cylinder 201 continues to move the first pressure plate 207 downward, thereby applying pressure to the material. The material under pressure simultaneously applies a reaction force to the first pressure plate 207, thereby squeezing the sponge 204. When the first pressure plate 207 is subjected to the reaction force, the reaction force is applied to the connecting rod 208 through the first pressure plate 207, and then the reaction force is applied to the first dynamometer 205 through the connecting rod 208, so that the first dynamometer 205 is pressed. The data of the dynamometer 205 gradually changes. Since the initial distance between the opposing sides of the first pressure plate 207 and the second pressure plate 2013 has been adjusted in advance and recorded by the central control system, and after the material is placed on the second pressure plate 2013, the distance the pull ring moves downward after the second dynamometer 209 generates the data is also recorded by the central control system. Therefore, when the downward distance of the first pressure plate 207 is equal to or greater than the initial distance between the opposing sides of the first pressure plate 207 and the second pressure plate 2013, and the data of the first dynamometer 205 has not changed, as the first pressure plate 207 continues to move downward until the first pressure plate 207 contacts the upper surface of the material, when the data of the first dynamometer 205 changes synchronously, it means that the thickness of the material is the distance the pull ring moves downward after the second dynamometer 209 generates the data minus the value C (the value C is: the total downward distance of the first pressure plate 207 minus the initial distance between the opposing sides of the first pressure plate 207 and the second pressure plate 2013).

[0039] If the downward movement distance of the first pressure plate 207 is less than the initial distance between the opposing sides of the first pressure plate 207 and the second pressure plate 2013 (i.e., after the first pressure plate 207 moves downward, the upper edge of the material is still within the initial distance between the opposing sides of the first pressure plate 207 and the second pressure plate 2013), and the data of the first force gauge 205 changes, it means that the thickness of the material is the distance of the downward movement of the pull ring generated by the second force gauge 209 plus the value D (the value D is: the initial distance between the opposing sides of the first pressure plate 207 and the second pressure plate 2013 minus the total downward movement distance of the first pressure plate 207).

[0040] According to the material thickness, the pressure value that the first pressure plate 207 needs to apply to the material is determined, that is, the data change of the first dynamometer 205. If the material thickness is proportional to the data change of the first dynamometer 205, and in order to ensure that the force on the upper and lower surfaces of the material is consistent and to prevent deformation of the force-bearing parts of the material, when the first pressure plate 207 applies pressure, the data of the first dynamometer 205 and the second dynamometer 209 change synchronously. According to the pressure value that needs to be applied to the material, assuming that a pressure value A needs to be applied to the material, it is only necessary to make the data of the first dynamometer 205 A, and the data of the second dynamometer 209 the value of A plus B, thereby ensuring that the material is subjected to uniform force.

[0041] When the first L-shaped plate 301 moves downward, the first L-shaped plate 301 drives the lower pressing plate 302 to move downward, and when it moves to contact the upper surface of the material, the cylinder 201 continues to drive the first L-shaped plate 301 to move downward, so that the lower pressing plate 302 applies pressure to the material, and the pressure value is proportional to the thickness of the material. At the same time, when the lower pressing plate 302 applies pressure to the material, it squeezes the limiting plate 307 at the same time, so that the limiting plate 307 drives the first fixing frame 305 to slide downward on the four round rods 304, and synchronously compresses the four first elastic members 303, so that the two first elastic members 303 have a buffering effect on the material. The effect is achieved, and other stress points of the material are also evenly stressed. At the same time, in order to ensure the smooth rotation of the material in the later stage, a number of round rollers are arranged on the facing surfaces of the lower pressure plate 302 and the limit plate 307, and the surface of the round rollers is smooth, thereby reducing the friction between the material and the lower pressure plate 302 and the limit plate 307, and preventing the material from being damaged. At the same time, when the material is rotated to cut the circle, the material before cutting the circle is smoothed by a number of round rollers to prevent it from affecting the cutting circle due to deformation and shaking. At the same time, after the cutting circle is completed, the edge of the material is polished, which effectively saves the subsequent manual polishing and prevents the burrs on the edge of the material after cutting the circle from scratching the workers.

[0042] When the lower pressing plate 302 is in the process of moving downward, the lower pressing plate 302 simultaneously drives the second L-shaped plate 401 to move downward, and limits the second L-shaped plate 401 through the second limiting rod 402, and then drives the pressing block 404 to slide downward in the pumping gas 403 through the second L-shaped plate 401. When the pressing block 404 slides downward, the gas inside the pumping gas 403 enters the hollow column 407 through the valve 405 and the connecting hose 406 at the bottom of the pumping gas 403, so that the internal air pressure of the hollow column 407 increases, and begins to push out the ejection rod 409, and the ejection rod 409 simultaneously drives the connecting body 4010 to move upward, and then drives the four locking columns 4011 to move upward through the connecting body 4010. Four openings are provided on the top, which are respectively matched with four locking columns 4011, so that the four locking columns 4011 enter the openings connected to the first fixing frame 305, and the connecting body 4010 supports the first fixing frame 305 in a limited position. At this time, the iron sheet is fixed, and the first servo motor 502 is controlled to start working. The first servo motor 502 drives the screw rod 503 to rotate, and then drives the support frame 505 to slide downward on the light rod 504 through the screw rod 503, that is, the second servo motor 506, the cutter 507 and the first connecting plate 3 are driven by the support frame 505 to move downward until the cutter 507 moves down to a suitable position for cutting the material into a circle, and then stops moving. At the same time, when the first connecting plate 3 moves downward, the bottom end of the first connecting plate 3 is The teeth of the gear 4016 drive the flat gear 4 to rotate, and then drive the second transmission shaft 4016 to rotate through the flat gear 4, the second transmission shaft 4016 rotates through the transmission group 4015 to drive the second bevel gear 4014 to rotate, the second bevel gear 4014 drives the first bevel gear 4013 to rotate, the first bevel gear 4013 drives the valve 405 to rotate through the first transmission shaft 4012, the valve 405 is in an open state in the initial state, as the first transmission shaft 4012 rotates, the valve 405 gradually closes, so that the gas between the gas 403 and the hollow column 407 is disconnected, the hollow column 407 is in a sealed state at this time, the gas in the hollow column 407 has nowhere to go, so that the ejection rod 409 is always in a pushed state, ensuring that the locking column 401 When entering the opening of the first fixing frame 305, the first fixing frame 305 is always in a locking state to ensure that when the material is cut into a circle, the material is prevented from shaking due to the shaking of the two first elastic members 303, and then the second servo motor 506 is controlled to start working, and the cutter 507 is driven by the second servo motor 506 to process the material. At the same time, the first electric shaft 202 and the second electric shaft 2012 are controlled to start working, so that the material rotates at a uniform speed and is smoothly cut into a circle by the cutter 507. When the circle cutting is completed, the cylinder 201 is controlled to start working again, and the fixed disc 203 and other components are driven to reset by the cylinder 201, and then the first servo motor 502 is synchronously controlled to start working again, so that the cutter 507 is reset.Then the workers take away the processed materials.
