Description

Technical Field

[0001] This invention relates to the field of metal sheet cutting technology, and in particular to a cutting device for processing metal sheets used in shipbuilding. Background Technology

[0002] Magnesium alloy sheet metal is widely used as a basic processing raw material in the forming and processing of components such as ship pipeline connectors, precision instrument terminals, and auxiliary supports for ship hull frames. When magnesium alloy sheet metal is used in shipbuilding, it needs to be cut to a fixed length, which requires the use of cutting equipment for processing sheet metal in shipbuilding.

[0003] Existing cutting devices often employ mechanisms to tighten and position sheet rolls. To prevent loosely wound sheet material from slipping off during the cutting process, these mechanisms typically include a stop and limit mechanism to prevent it from sliding off. However, to prevent this stop and limit mechanism from remaining in an outwardly protruding state when the sheet roll is placed onto the tightening and positioning mechanism, thus hindering the placement and potentially causing hand injuries to workers, these mechanisms are often designed to be retractable. However, switching between retraction and extension of the stop and limit mechanism before and after sheet roll placement requires additional manual effort, which is cumbersome and indirectly reduces the efficiency of sheet roll placement. Summary of the Invention

[0004] In view of this, the present invention provides a cutting device for processing metal sheets for shipbuilding, so as to solve the problem that the telescopic switching operation of the blocking and limiting mechanism before and after the sheet roll placement operation requires additional manual force, which is quite troublesome and inconvenient.

[0005] The technical solution proposed in this invention is as follows: a cutting device for processing metal plates in shipbuilding, specifically comprising a plate support plate and a support column. The plate support plate has multiple through-cut strip grooves, and a guide shaft is fixedly connected inside each strip groove. A sliding element is integrally formed at the bottom end of the support column, slidingly engaging with the strip grooves and the guide shaft. A collar is slidably fitted onto the guide shaft by a spring-loaded mechanism. A horizontal stop bar is slidably installed at the top of the support column. A T-shaped slider that slides vertically is mounted on the support column. An upward-tilting connecting rod and a downward-tilting connecting rod are rotatably connected to the T-shaped slider, the collar, and the horizontal stop bar, respectively. A threaded propulsion shaft is rotatably installed at the center of the plate support plate. A threaded sleeve is threaded onto the outer circumference of the threaded propulsion shaft, and a connecting rod is rotatably connected to the support column. When the support column slides toward the threaded propulsion shaft, it causes the collar to abut against the end of the strip groove closest to the threaded propulsion shaft.

[0006] Furthermore, a T-shaped groove is provided on the outer periphery of the support column, and the T-shaped slider slides in cooperation with the T-shaped groove.

[0007] Furthermore, the spring that pushes the collar is mounted on the guide shaft and is compressed and clamped between the collar and the sliding member.

[0008] Furthermore, the sheet metal roll is mounted on multiple support columns and is secured and positioned by multiple outwardly sliding support columns. When the horizontal stop bar slides outward and protrudes from the support columns, it is used to prevent and limit the loose and slipping roll of sheet metal.

[0009] Furthermore, it also includes a cutting table, one end of which is integrally formed with a U-shaped support frame, and a track ring with a U-shaped cross-section structure is welded on the top of the U-shaped support frame. The outer edge of the plate bearing plate rotates and engages with the track ring.

[0010] Furthermore, the top of the cutting table is sequentially fixed with spaced-apart plate guides, T-shaped mounting plates, and rectangular mounting platforms. A vertical support mounting plate is welded to the top of the cutting table on the side of the plate guide. A wire-passing hole is opened through the center of the upper half of the plate guide. A hydraulic cylinder is fixedly installed on the upper half of the vertical support mounting plate.

[0011] Furthermore, two plate traction wheels are symmetrically and rotatably installed at the top of the vertical part of the T-shaped mounting plate. The tail end of the shaft of the two plate traction wheels is fixedly fitted with a sprocket. A U-shaped mounting frame is welded to the bottom side of the vertical part of the T-shaped mounting plate. A drive assembly is fixedly installed inside the U-shaped mounting frame. A sprocket is fixedly fitted at the beginning of the power output shaft of the drive assembly. Chains are installed on the three sprockets.

[0012] A horizontal slide plate is slidably installed above the T-shaped mounting plate. Two plate traction wheels are symmetrically rotated on the horizontal slide plate. Two slide bars are integrally formed at the bottom of both ends of the horizontal slide plate. Two vertical slide grooves are symmetrically opened at both ends of the vertical part of the T-shaped mounting plate. The slide bars slide in conjunction with the vertical slide grooves. When the two upper plate traction wheels and the two lower plate traction wheels press against each other, a compression conveying gap is formed between the four.

[0013] Two threaded drive shafts are symmetrically mounted on the top of the T-shaped mounting plate, and both threaded drive shafts are threadedly engaged with the horizontal sliding plate.

[0014] Furthermore, two rows of staggered plate guide wheels are fixedly installed at the top of the rectangular mounting platform, forming a conveying gap between the two rows of plate guide wheels. Straight plates drawn from the plate roll are sequentially guided through the conveying gap, the extrusion conveying gap, and the threading hole.

[0015] Furthermore, a guide rod is fixedly connected to one end of the upper half of the plate through the plate, and a T-shaped cutter is slidably installed on the guide rod. The first end of the hydraulic cylinder piston rod is fixedly connected to the T-shaped cutter. The first end of the T-shaped cutter has a beveled blade structure and slides against a wide side of the plate through the plate.

[0016] The present invention provides a cutting device for processing metal sheets used in shipbuilding and processing, which has the following beneficial effects:

[0017] 1. The horizontal stops are telescopically slidable. In the cutting and processing state, the multiple horizontal stops distributed around the column are kept in the unfolded state of sliding outwards from the support column. At this time, the multiple sliding and protruding horizontal stops are used to prevent the loose and slipping rolled-up plate from falling off the support column during the cutting and processing process, thus affecting the continuous and effective cutting and processing operation.

[0018] 2. When reloading a new sheet metal roll after the unwinding of the sheet metal roll has been completed, the multiple horizontal stop bars distributed around the roll are kept in the inward sliding retracted position. In this state, the retracted horizontal stop bars are hidden in the tensioning columns, and the main body of the horizontal stop bars slides inward in the surrounding space between the tensioning columns in the retracted state. In this retracted state, the multiple horizontal stop bars can avoid protruding obstruction and interference to the reloading of the sheet metal roll, ensuring unobstructed and smooth assembly of the sheet metal roll. It can also prevent protruding collision injuries to workers' hands during the reloading process, which helps to ensure the safety of sheet metal roll loading operations.

[0019] Third, by using the power transmission of the multi-link slider mechanism and matching the counter-pushing holding effect of the spring on the guide shaft, the extension and retraction of the horizontal stop bar before and after loading the sheet roll can be driven by the sliding force of the support column. This eliminates the trouble of manually performing the extension and retraction of the horizontal stop bar before and after loading the sheet roll, making the operation more convenient and time-saving, and indirectly helping to improve the loading efficiency of the sheet roll.

[0056] Preferably, two rows of staggered plate guide wheels 3 are fixedly installed at the top of the rectangular mounting platform 2, and a conveying gap is formed between the two rows of plate guide wheels 3.

An electrical control box 10 is fixedly installed on one of the convex frames 102, and the electrical control box 10 contains a control unit and a servo driver.

[0059] The drive assembly 15 is integrally formed by the servo motor and the reducer. The hydraulic cylinder 12 is connected to the external hydraulic power unit through the high-pressure oil pipe. The high-pressure oil pipe is connected to the solenoid valve. The control unit is communicatively connected to the servo driver, the control unit is electrically connected to the solenoid valve, and the servo driver is electrically connected to the servo motor.

[0060] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below:

[0061] When performing fixed-length cutting of metal sheets, the sheet roll 11 is first inserted and placed on the multiple tensioning columns 8 in an inwardly retracted state. Then, the multiple tensioning columns 8 are driven to simultaneously slide outward and unfold, tightening and positioning the installed sheet roll 11. Subsequently, the straight sheet 1101 led out from the sheet roll 11 is sequentially guided through the conveying gap, the extrusion conveying gap, and the threading hole. Next, the drive assembly 15 is started by the control unit. After the drive assembly 15 is started, it rotates a preset number of times under the joint control of the control program and the servo driver inside the control unit. Due to the pressure and contact of the four sheet traction wheels 4 at the top and bottom, the sheet roll is cut into place. Through the power transmission of chain 14, the drive assembly 15, once started, can synchronously rotate to drive the upper plate traction wheel 4 and the two lower plate traction wheels 4 to rotate in opposite directions. When the four plate traction wheels 4 are driven to rotate synchronously in opposite directions, the straight plate 1101 can be continuously pulled and conveyed towards the wire hole under the action of rotational extrusion pressure. When the straight plate 1101 is being pulled and conveyed, the traction force acting on it can pull and drive the plate roll 11, multiple tensioning columns 8, and plate bearing plate 5 to rotate around the track ring 1011, controlling the unwinding and wire feeding of the plate roll 11. Since the drive assembly 15 rotates a predetermined number of times under the program setting, The four traction wheels 4 are also limited in the number of rotations. Based on this limited number of rotations, the four traction wheels 4 can perform fixed-length traction and conveying of the straight sheet 1101. After the drive assembly 15 has rotated a set number of times to traction and convey the straight sheet 1101 to the specified length, it automatically stops under the joint control of the control program and the servo drive, keeping the straight sheet 1101 at the specified traction and conveying length. Simultaneously, the control unit switches the oil circuit of the hydraulic cylinder 12 by controlling the on / off state of the solenoid valve, manipulating the extension rod of the hydraulic cylinder 12 to quickly extend and retract one stroke. During this extension and retraction stroke, the hydraulic cylinder 12... When the piston rod extends, it pushes and drives the T-shaped cutter 601 to slide toward the straight plate 1101 to complete one fixed-length cutting of the straight plate 1101. When the piston rod of the hydraulic cylinder 12 retracts, it separates from the wire hole and opens the wire hole to remove the obstruction of the wire hole. After the piston rod retracts back to its original position, its return signal is transmitted to the control unit. The control unit triggers the start of the drive assembly 15 through the received return signal. After the drive assembly 15 is restarted, the drive assembly 15 repeats the above process with the above-mentioned components or parts. By repeating this process, continuous fixed-length cutting of the straight plate 1101 can be achieved.

[0062] The threaded sleeve 504, multiple connecting rods 5041, and multiple sliding parts 805 are connected together to form a multi-crank slider mechanism with a ring structure. Through this mechanism, the forward and reverse rotation of the threaded push shaft 503 can drive the threaded sleeve 504 to slide up and down, control the multiple sliding parts 805 and the tensioning column 8 to slide synchronously inside and outside, and implement tensioning, positioning and unlocking of the plate roll 11.

[0063] The horizontal stop bar 801 is telescopically slidably installed. During cutting operations, the multiple horizontal stop bars 801, distributed around the perimeter, are kept in an extended state, sliding outwards and protruding from the support column 8. In this state, the multiple sliding protruding horizontal stop bars 801 prevent the loose and slipping coiled sheet material from the sheet roll 11, thus avoiding the coiled sheet material from falling off the support column 8 during cutting and affecting the continuous and effective cutting operation. When a new sheet roll 11 is reloaded after the sheet roll 11 has been unwound and consumed, the multiple horizontal stop bars 801... The plate roll 801 is kept in the inward sliding retracted position. In this state, the retracted horizontal stops 801 are hidden in the tensioning column 8, and the main body of the horizontal stops 801 is slid inward in the surrounding space between the tensioning columns 8 in the retracted state. In this retracted state, the horizontal stops 801 can avoid protruding obstruction and interference during the reloading of the plate roll 11, ensuring the smooth and unobstructed assembly of the plate roll 11. It can also prevent protruding collision injuries to the workers' hands during the reloading process, which helps to ensure the safety of the plate roll 11 loading operation.

[0064] A set of downward tilting connecting rods 8011, T-shaped sliders 802, a set of upward tilting connecting rods 803, collars 804, and horizontal stop rods 801 together form a multi-link slider mechanism. Through this mechanism, the horizontal stop rods 801 can be driven to slide inward and outward by sliding the collars 804 toward or away from the threaded push shaft 503.

[0065] When reloading the sheet metal roll 11, the multiple tensioning columns 8 need to be slid inward to reduce their diameter, creating more space around them for easy placement of the sheet metal roll 11. When the tensioning columns 8 are slid inward, the spring on the guide shaft 502 pushes the collar 804 towards the threaded push shaft 503, making contact with the end of the strip groove 501 near the threaded push shaft 503. In this contact state, as the tensioning columns 8 continue to slide inward, the collar 804 is pushed back by the end of the threaded push shaft 503, compressing the spring on the guide shaft 502 and causing it to slide towards the sliding member 805, thus automatically retracting the horizontal stop lever 801 inward. After reloading the sheet metal roll 11, the tensioning columns 8, now in a retracted state, need to be slid outward to tighten and position the newly loaded sheet metal roll 11. As the support column 8 is driven to slide outward, it gradually moves away from the threaded push shaft 503. In the initial stage of this process, the collar 804, under the counter-push of the compressed spring, remains in contact with the end of the strip groove 501 near the threaded push shaft 503. Then, in this initial stage, the collar 804 slides away from the support column 8 and drives the horizontal stop bar 801, which is inwardly retracted, to slide outward. In this way, through the power transmission of the multi-link slider mechanism and the counter-push holding effect of the spring on the guide shaft 502, the extension and retraction of the horizontal stop bar 801 before and after loading the plate roll 11 can be driven by the driving force of the extension and retraction of the support column 8. This eliminates the trouble of manually performing the extension and retraction of the horizontal stop bar 801 before and after loading the plate roll 11. The operation is more convenient and time-saving, which helps to indirectly improve the loading efficiency of the plate roll 11.

[0066] It is worth noting that the composition of the control unit, the selection of the solenoid valve model, the preset control program in the control unit, the connection and wiring method between the control unit and the servo driver and the solenoid valve, the connection and wiring method between the servo driver and the servo motor, and the control principle of the control unit for the servo motor are all existing technologies for technicians engaged in the electrical automation transformation, design, upgrading and testing of equipment in this field, and therefore will not be elaborated here.
