Description

Technical Field

[0001] The invention relates to the technical field of steel material processing, in particular to a hydraulic shearing machine for steel material processing. Background Art

[0002] The gantry hydraulic shearing machine is a mechanical equipment driven by a hydraulic system. It is mainly used for cutting various metal plates, profiles and other materials. It has a fixed lower cutter and an upper cutter driven by a hydraulic cylinder to move up and down. When the hydraulic shearing machine is working, the hydraulic system is controlled to make the upper cutter move downward to complete the shearing action.

[0003] When using a hydraulic shear to recycle and shear steel, there will be a lot of rust impurities on the surface of the steel. During the shearing process, the impurities on the surface of the steel will remain and gradually accumulate on the cutting surface of the upper cutter. When the upper and lower sets of cutters are close to each other and rub against each other, the upper and lower sets of cutters are mixed with rust impurities and rub against each other, which aggravates the wear of the cutters and reduces the service life of the equipment.

[0004] Furthermore, in order to enhance the protection of the cutter during the shearing process, cutting oil is applied to the cutter. During shearing, the cutting surfaces of the upper cutter and the lower cutter continuously rub against each other, causing the cutting oil on the cutting surfaces of the upper cutter and the lower cutter to be scraped off each other. After the cutter loses the protection of the cutting oil, the friction between the cutter and the steel increases, resulting in increased wear on the blade surface. Summary of the invention

[0005] In order to overcome the disadvantages of the existing gantry hydraulic shearing machine that the cutting blades are easily adhered to rust impurities on the steel, and at the same time, the cutting oil on the cutting surfaces of the upper and lower cutting blades are scraped off each other, the friction between the cutting blades is increased, and the wear of the cutting blades is aggravated, the present invention provides a hydraulic shearing machine for processing steel materials.

[0008] Furthermore, a plurality of cleaning parts for cleaning the limiting grooves are arranged on the lower side of the fixing frame; each cleaning part slides in the corresponding limiting groove.

[0009] Furthermore, it also includes a collecting component, which includes a third driving member and a collecting box; a plurality of third driving members are fixedly connected to the upper side of the pressing block; a collecting box for collecting metal debris is commonly fixedly connected to the telescopic ends of all the third driving members; an opening is provided on the front side of the collecting box; and a scraper is fixedly connected to the lower front side of the collecting box.

DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figure 1-Figure 8 As shown, a hydraulic shearing machine for processing steel materials comprises a frame 1;

[0032] It also includes a power assembly, an upper cutter 103, a pressing block 105, a slider 106, a lower cutter 107 and a scraper 2; a power assembly is arranged on the frame 1; the upper cutter 103 is connected to the power assembly; the pressing block 105 is connected to the power assembly; two sliders 106 which are symmetrical on the left and right are slidably connected to the frame 1; the lower cutter 107 is connected to all the sliders 106 for rotation together; the scraper 2 is slidably connected to the pressing block 105; the scraper 2 is made of hard material; the front end of the scraper 2 is arranged to be in an upward state.

[0033] The power assembly includes a first driving member 101, a fixing frame 102 and a second driving member 104; a plurality of left-right symmetrical first driving members 101 are fixedly connected to the upper side of the frame 1, and the first driving members 101 are electric hydraulic rods; a fixing frame 102 is fixedly connected to the telescopic ends of all the first driving members 101; the fixing frame 102 is connected to the upper cutter 103 by a latch; two left-right symmetrical limiting grooves 1001 are provided on the frame 1; the fixing frame 102 slides in the limiting grooves 1001; a plurality of left-right symmetrical second driving members 104 are fixedly connected to the upper side of the frame 1, and the second driving members 104 are electric hydraulic rods; the telescopic ends of all the second driving members 104 are fixedly connected to the pressing block 105.

[0034] Two cleaning parts 10201 that are symmetrical to each other are disposed on the lower side of the fixing frame 102 ; each cleaning part 10201 slides in the corresponding limiting groove 1001 .

[0035] It also includes a collecting component, which includes a third driving member 201 and a collecting box 202; two third driving members 201 that are symmetrical on the left and right are fixedly connected to the upper side of the pressing block 105, and the third driving member 201 is an electric push rod; a collecting box 202 is commonly fixedly connected to the telescopic ends of all the third driving members 201; an opening is provided on the front side of the collecting box 202; and the scraper 2 is fixedly connected to the lower front side of the collecting box 202.

[0036] Furthermore, in order to prevent the scraped impurities from overflowing from the collection box 202, the inner bottom of the collection box 202 is configured to be in a concave arc state with a high front and a low back, thereby enhancing the collection effect of the collection box 202 on impurities.

[0037] It also includes a blocking rod 301; an oil storage chamber 10202 is opened at the rear side of the fixing frame 102; and the blocking rod 301 is rotatably connected to the rear part of the lower side of the fixing frame 102 through a torsion spring.

[0038] A temporary storage groove 10203 is provided at the lower rear portion of the fixing frame 102 ; the temporary storage groove 10203 is communicated with the oil storage chamber 10202 ; and the temporary storage groove 10203 is located on the upper side of the blocking rod 301 .

[0039] Furthermore, in order to allow the oil in the oil storage chamber 10202 to be fully discharged, the connection point between the bottom of the oil storage chamber 10202 and the temporary storage groove 10203 is set to be in a downward concave state.

[0040] Two grooves 10301 are provided on the rear side of the upper cutter 103; the lower end of the blocking rod 301 is inserted into the groove 10301 on the lower side.

[0041] The present invention drives the scraper 2 to rise together with the pressing block 105 during the rising process, so that the scraper 2 scrapes off the metal debris adhered to the cutting surface of the upper cutter 103, thereby solving the problem that the upper cutter 103 is mixed with metal debris and rubs against the lower cutter 107 during the subsequent shearing process, which aggravates the wear of the cutter and reduces the service life of the equipment. The specific process is as follows:

[0042] When the hydraulic shearing machine is used to shear the steel plate, the steel plate is transferred to the lower cutter 107 through the conveying mechanism, and then the second driving member 104 is controlled to drive the pressing block 105 to descend to press and fix the steel plate. After the steel plate is fixed, the first driving member 101 is controlled to drive the fixing frame 102 to descend in the limiting groove 1001, and the fixing frame 102 is limited by the limiting groove 1001 to prevent the fixing frame 102 from driving the upper cutter 103 to deviate to the front and rear sides during the shearing process, thereby ensuring the upper cutter 1 03 has a shearing effect on the steel plate. The fixing frame 102 drives the upper cutter 103 to descend during the descending process. The steel plate is cut off by the shearing force applied to the steel plate by the upper cutter 103 and the lower cutter 107. The shearing of the steel plate is completed. When the fixing frame 102 descends in the limiting groove 1001, the cleaning part 10201 squeezes the steel fragments stuck in the limiting groove 1001 to the outside of the limiting groove 1001 to prevent the steel fragments stuck in the limiting groove 1001 from blocking the fixing frame 102 from descending, thereby avoiding affecting the normal operation of the upper cutter 103.

[0043] After the steel plate is cut, the first driving member 101 is controlled to drive the fixing frame 102 and the upper cutter 103 to reset, and then the third driving member 201 is controlled to drive the collecting box 202 to extend, so that the scraper 2 and the rear side of the upper cutter 103 are in the same vertical plane, and then the second driving member 104 is controlled to drive the pressing block 105 to rise. During this process, the pressing block 105 drives the collecting box 202 to rise together with the scraper 2, so that the upper end of the scraper 2 is close to the rear side of the upper cutter 103. As the pressing block 105 drives the scraper 2 to continue to rise, the scraper 2 is scraped off the metal debris adhered to the cutting surface of the rear side of the upper cutter 103, and the metal debris flows along the upper side of the scraper 2 to the collecting box 202, so as to prevent the upper cutter 103 from mixing with metal debris and rubbing against the lower cutter 107, thereby avoiding aggravated wear of the cutter and improving the service life of the equipment.

[0044] It is also considered that during the cutting process, the cutting surface of the upper cutter 103 and the cutting surface of the steel plate rub against each other, so that the cutting oil on the cutting surface of the upper cutter 103 is scraped off by the steel plate. After losing the protection of the cutting oil, the friction between the upper cutter 103 and the lower cutter 107 increases, resulting in increased wear of the upper cutter 103 and the lower cutter 107. The specific solution process is as follows:

[0045] Before cutting the steel plate, the staff adds cutting oil used to reduce the friction between the upper cutter 103 and the lower cutter 107 into the oil storage chamber 10202. After entering the oil storage chamber 10202, the cutting oil flows downward to the temporary storage tank 10203. During this process, the cutting oil entering the temporary storage tank 10203 is blocked by the blocking rod 301. After the scraper 2 rises to scrape off the metal debris adhered to the rear side of the upper cutter 103, as the scraper 2 continues to rise, the scraper 2 contacts the blocking rod 301. During this process, the lower end of the blocking rod 301 is stuck in the groove 10301 to prevent the scraper 2 from being inserted between the blocking rod 301 and the upper cutter 103 when passing through the blocking rod 301, and to prevent the metal debris on the scraper 2 from re-adhering to the upper cutter 103. After the scraper 2 contacts the blocking rod 301, the third driving member 201 is controlled to drive the collecting box 202 to contract, so that the scraper 2 moves backward along the rear side of the blocking rod 301, and then the scraper 2 pushes the rear side of the blocking rod 301 upward, and at the same time compresses the blocking rod 301 and the fixing frame 1 02, the torsion spring between the blocking rod 301 rotates counterclockwise, releasing the blocking of the temporary storage groove 10203 by the blocking rod 301, so that the cutting oil in the temporary storage groove 10203 flows downward evenly along the rear side of the upper cutter 103. When the shearing work is performed next time, the cutting surface of the upper cutter 103 carries the cutting oil and contacts the lower cutter 107, preventing the upper cutter 103 from losing the protection of the cutting oil and causing the friction with the lower cutter 107 to increase, thereby enhancing the protection effect of the upper cutter 103 and the lower cutter 107. After passing through the blocking rod 301, the blocking rod 301 rotates and resets under the action of the elastic force of the torsion spring, and the temporary storage groove 10203 is resealed. When the steel plate is sheared next time, the second driving member 104 drives the pressing block 105 to descend again. At this time, the third driving member 201 drives the collecting box 202 and the scraper 2 to be in a retracted state, so that the scraper 2 is away from the upper cutter 103. The scraper 2 does not contact the upper cutter 103 when the pressing block 105 descends, preventing the scraper 2 from scraping the cutting oil on the cutting surface of the upper cutter 103 when it descends.

[0046] It is also considered that when the upper cutter 103 and the lower cutter 107 are severely worn or broken, the shearing force on the steel plate will increase, which requires greater pressure to complete the shearing, increasing the energy consumption of the equipment. The edge of the steel plate after shearing may be uneven, and burrs, cracks and other problems may occur, which not only increases the risk of equipment damage, but also reduces the shearing quality. The specific solution process is as follows:

[0047] When the upper cutter 103 and the lower cutter 107 are severely worn or broken, the staff will pull out the pins fixing the left and right parts of the upper cutter 103 from the upper cutter 103, then rotate the upper cutter 103 on the fixing frame 102 by 180 degrees, and rotate the cutting part on the upper side of the upper cutter 103 to the lower side for use, so that the upper cutter 103 can resume cutting work, and then the staff will pull the slider 106 together with the lower cutter 107 forward on the frame 1, and after the lower end of the lower cutter 107 loses the support of the frame 1, the lower cutter 107 is rotated 180 degrees on the slider 106, and the cutting part on the lower side of the lower cutter 107 is rotated to the upper side for use, thereby realizing convenient adjustment of the upper cutter 103 and the lower cutter 107 that are severely worn or broken.

[0048] Example 2

[0049] On the basis of Example 1, Figure 1-Figure 3 As shown, a roller conveyor belt 401 is also included; the roller conveyor belt 401 is arranged on the rear side of the frame 1.

[0050] It is also considered that after the upper cutter 103 completes shearing of the steel plate, the cutting oil and metal debris adhered to the rear side of the upper cutter 103 will remain on the upper side of the shearing cut of the steel plate. When the upper cutter 103 rises, the cutting oil and metal debris remaining on the upper side of the shearing cut of the steel plate and the rear side of the upper cutter 103 will drip downward onto the cutting surface of the lower cutter 107. When the steel plate is sheared next time, the cutting oil and metal debris dripping onto the cutting surface of the lower cutter 107 will increase the friction between the upper cutter 103 and the lower cutter 107. The specific solution process is as follows:

[0051] When the upper cutter 103 completes shearing of the steel plate and moves upward to reset, the pressing block 105 is synchronously controlled to rise so that it no longer presses the steel plate. When the rising distance of the upper cutter 103 is greater than the thickness of the steel plate, the roller conveyor 401 is controlled to drive the steel plate to move forward to feed the material, which can prevent the cutting oil and metal debris on the upper side of the shearing edge of the steel plate from dripping onto the lower cutter 107, and at the same time use the steel plate to shield the lower cutter 107 (since the steel plates in the shearing process are mostly waste recycled materials and rough-processed products, and the amount of cutting oil is small, it will not affect other subsequent processing operations of the steel plate), and prevent the cutting oil and metal debris adhered to the rear side of the upper cutter 103 from dripping onto the lower cutter 107, thereby effectively reducing the wear between the upper cutter 103 and the lower cutter 107 and enhancing the protection effect on the equipment.

[0052] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
