Description

Technical Field

[0001] This invention relates to the field of plate shearing technology, and in particular to a hydraulic plate shearing machine with a correction structure. Background Technology

[0002] Currently, most shearing machines on the market rely on manual feeding of sheet metal. When shearing larger sheets, the operator needs to lift the sheet onto the feeding platform, push it forward until it rests against the rear baffle for positioning, and then cut it. Positioning during the cutting process requires pre-marking lines on the sheet, clamping it with the machine's clamping device, and finally activating the transmission system to drive the cutter. Because positioning via marking and clamping results in low accuracy and difficulty in adjustment, it increases the labor intensity of manual feeding. Summary of the Invention

[0034] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a hydraulic shearing machine with a correction structure, which includes a shearing unit 100, including a frame 101, a pair of hydraulic cylinders 102 disposed at the upper end of the frame 101, a pair of cutters 103 disposed at the bottom of the hydraulic cylinders 102, a pair of columns 104 disposed on both sides of the frame 101, and a sleeve 105 disposed on the column body of the columns 104.

[0038] Furthermore, the correction assembly 205 includes a correction clip 205a and a correction plate 205b disposed on one side of the correction clip 205.

[0039] Furthermore, the alignment clamp 205a includes a pair of first sliding seats 205a-1 disposed at its bottom, a first positioning post 205a-2 disposed on one side of the alignment clamp 205, an active hole 205a-3 disposed on the other side of the alignment clamp 205, a base plate 205a-4 disposed on the other side of the alignment clamp 205, and an arc-shaped groove 205a-5 that penetrates the surface of the base plate 205a-4.

[0040] Furthermore, the correction plate 205b includes a movable column 205b-1 disposed on one side thereof, a limiting groove 205b-2 disposed on one side of the movable column 205b-1, a pair of first pressing columns 205b-3 disposed on the other side of the correction plate 205b, and a return spring 205b-4 disposed on the column body of the movable column 205b-1.

[0041] Furthermore, the auxiliary component 206 includes an auxiliary clamp 206a and an auxiliary plate 206b disposed on one side of the auxiliary clamp 206a.

[0042] Furthermore, the auxiliary clamp 206a includes a second sliding seat 206a-1 disposed at its bottom and a second positioning post 206a-2 disposed on one side of the auxiliary clamp 206a.

[0043] Furthermore, the auxiliary plate 206b includes a limiting block 206b-1 disposed on one side thereon, and a pair of second clamping posts 206b-2 disposed on the other side of the auxiliary plate 206b.

[0044] Furthermore, the extension roller 207 includes a knurled rod 207a, a pair of lead screws 207b disposed on both sides of the knurled rod 207a, an internal threaded rod 207c disposed on the body of the lead screw 207b, and a first set of rods 207d disposed on one side of the internal threaded rod 207c.

[0045] The telescopic roller 208 includes a hollow rod 208a, an extension rod 208b disposed on one side of the hollow rod 208a, a thin rod 208c disposed on one side of the extension rod 208b, and a second set of rods 208d disposed on one side of the hollow rod 208a and the extension rod 208b respectively.

[0046] The first set of rods 207d and the second set of rods 208d each have two copies, and their shapes and functions are identical; the lead screw 207b has two copies, and the threads of the two lead screws 207b are opposite to each other.

[0047] Furthermore, the adjusting gear 301 includes a cam 301a disposed on its top;

[0048] The transmission gear 302 includes a torque tube 302a disposed on its top and a torque groove 302b disposed on the upper end of the torque tube 302a.

[0049] Furthermore, the push plate 402 includes a pair of balance bars 402a disposed on one side thereof.

[0050] It should be noted that the shearing unit 100 is used for cutting the board material. There is a pair of evenly distributed hydraulic cylinders 102 on the top of the frame 101. The upper part of the cutter 103 is fixedly connected to the bottom of the two hydraulic cylinders 102. When the hydraulic cylinders 102 are activated, the upper part of the cutter 103 moves up and down in a straight line. The sleeve 104 is fixedly connected to the upper part of the cutter 103 and cooperates with the columns 104 on both sides of the frame 101. The two can move together to ensure the stability of the movement of the upper part of the cutter 103. The lower part of the cutter 103 is fixed in the middle of the frame 101. When the upper part of the cutter 103 falls, it works together with the lower part of the cutter 103 to cut the board material. At this time, the upper and lower parts of the cutter 103 are in contact with each other.

[0051] For a better option, refer to the appendix. Figure 4 The workbench 201 is fixed at the feed inlet of the frame 101 to assist in the cutting of the sheet metal placed on the workbench 201. A pair of slide rails 202 are fixedly connected to the bottom of the frame 101. The slide rails 202 are used for the cooperation of the first sliding seat 205a-1 and the second sliding seat 206a-1 to ensure the lateral linear movement of the first sliding seat 205a-1 and the second sliding seat 206a-1. In addition, there is a limiting structure between the two to prevent the first sliding seat 205a-1 and the second sliding seat 206a-1 from falling off during movement. There is a platform for mounting the rotating arm 203 at the center between the two slide rails 202. At this time, the rotating arm 203 can be movably connected to the cylinder on the aforementioned platform to ensure that the rotating arm 203 can rotate.

[0052] See attached document Figure 5 There are two hinge rods 204. One is used for the hinge between the first sliding seat 205a-1 and one side of the rotating arm 203, and the other is used for the hinge on the other side of the second sliding seat 206a-1 and the rotating arm 203. Therefore, when either the first sliding seat 205a-1 or the second sliding seat 206a-1 moves, the other sliding seat moves by the same distance, ensuring that the two sliding seats can move simultaneously and that their movement states and distances are consistent.

[0053] Preferably, the correction component 205 and the auxiliary component 206 are respectively installed on both sides of a pair of slide rails 202 and are moved by the first sliding seat 205a-1 and the second sliding seat 206a-1 respectively. On the worktable 201, there are extension rollers 207 and telescopic rollers 208. The two rollers are simultaneously movably connected to the correction component 205 and the auxiliary component 206. The compression spring 209 is used for the pressing action of the two rollers.

[0054] Preferably, the correction component 205 consists of a correction clip 205a and a correction plate 205b, and the auxiliary component 206 consists of an auxiliary clip 206a and an auxiliary plate 206b. The two components need to be used in pairs to achieve the correction effect.

[0055] For a better option, refer to the appendix. Figure 6 The overall shape of the alignment clamp 205a consists of two C-shaped structural steels welded together to the first sliding seat 205a-1. A downward-facing first positioning post 205a-2 is fixed to the upper end of one of the C-shaped structural steels, which can be hinged to the alignment plate 205b. A movable hole 205a-3 is formed on the other C-shaped structural steel, with the opening facing the direction of the slide rail 202, for inserting the movable post 205b-1. It should be noted that the diameter of the movable post 205b-1 is smaller than that of the movable hole. The aperture of hole 205a-3 provides sufficient movement allowance for the adjustment and movement of the correction plate 205b. A horizontal base plate 205a-4 is fixed at the bottom of the movable hole 205a-3 to support the adjustment unit 300. The base plate 205a-4 has a through arc-shaped groove 205a-5 to accommodate the locking bolt 303. The locking bolt 303 locks the base plate 205a-4 and the transmission gear 302, ensuring that the transmission gear 302 will not move after being locked. It should be noted that the arc-shaped groove 205a-5 is concentric with the transmission gear 302, which allows the locking bolt 303 to be placed directly in the tooth gap of the transmission gear 302 and move along the trajectory of the arc-shaped groove 205a-5 as the transmission gear 302 rotates.

[0056] Preferably, the positioning posture of the correction plate 205b is determined by a hinge and the insertion of the movable column 205b-1 into the movable hole 205a-3. Furthermore, a circular washer for limiting the return spring 205b-4 is fixed to the end of the movable column 205b-1. Therefore, the return spring 205b-4 is fitted onto the column body of the movable column 205b-1 and simultaneously fixedly connected to the aforementioned circular washer and the opening of the movable hole 205a-3, ensuring that the correction plate 205b is securely mounted on the correction clamp 205a. The limiting groove 205b-2 is a square straight groove opened on the side of the straightening plate 205b near the movable column 205b-1. It is used for the engagement with the cam 301a. The upper and lower groove walls of the limiting groove 205b-2 are in close contact with the upper and lower surfaces of the cam 301a. Since there is a large gap between the movable hole 205a-3 and the movable column 205b-1, it is used to further support and limit the movement of the straightening plate 205b during adjustment. The side wall of the cam 301a directly acts on the bottom of the limiting groove 205b-2. There are two first clamping columns 205b-3, which are symmetrically distributed on the side of the straightening plate 205b and fixedly connected to the straightening plate 205b. The first clamping columns 205b-3 face upward.

[0057] For a better option, refer to the appendix. Figure 5The auxiliary clamp 206a is similar in shape to the correction clamp 205, and is also composed of two C-shaped structural steels welded to the second sliding seat 206a-1. A downward-facing second positioning post 206a-2 is fixed to the upper end of one of the C-shaped structural steels, which can be hinged to the auxiliary plate 206b. It should be noted that the line connecting the centers of the second positioning post 206a-2 and the first positioning post 205a-2 is parallel to the slide rail 202.

[0058] Preferably, the auxiliary plate 206b is similar in shape to the correction plate 205b, and the limiting block 206b-1 is fixed on one side of the auxiliary plate 206b, corresponding to the position of another C-shaped structural steel on the auxiliary clamp 206a. The limiting block 206b-1 can be placed on the upper end of the aforementioned C-shaped structural steel, and the two can slide relative to each other. When the auxiliary plate 206b is driven to shift, the limiting block 206b-1 supports the auxiliary plate 206b while moving in a sliding manner on the upper end of the aforementioned C-shaped structural steel.

[0059] Preferably, the extension roller 207 is hinged to the first pressing column 205b-3 and the second pressing column 206b-2 via the first sleeve rods 207d on both sides, and the telescopic roller 208 is hinged to the first pressing column 205b-3 and the second pressing column 206b-2 via the second sleeve rods 208d on both sides. Therefore, the extension roller 207, the telescopic roller 208, the correction plate 205b and the auxiliary clamp 206a can form a deformable parallelogram. When the first rod 207d and the second rod 208d are hinged to the corresponding pressing column, a compression spring 209 is provided at the hinge point, for a total of four. Each pressing column has a limit disc for installing and fixing the compression spring 209. The two ends of the compression spring 209 are fixedly connected to the aforementioned limit disc and the hinge point of the rod, respectively. The compression spring 209 can press the extension roller 207 and the telescopic roller 208 downward. When a plate passes under the former two, the extension roller 207 and the telescopic roller 208 are lifted up in sequence and rotate with themselves. Under the action of the compression spring 209, the plate can be pressed.

[0060] Preferably, the extension roller 207 is composed of a knurled rod 207a and two symmetrical internally threaded rods 207c. The two internally threaded rods 207c are threadedly connected to lead screws 207b respectively. Since the thread directions of the pair of lead screws 207b are opposite to each other, when the operator rotates the knurled rod 207a, the two internally threaded rods 207c move inward or outward simultaneously. Unlike the rotating arm 203 and the hinge rod 204, it does not have the ability to symmetrically install the correction assembly 205 and the auxiliary assembly 206 on the worktable 201. It can only adjust the spacing between the aforementioned two assemblies. The two ends of the two internally threaded rods 207c are movably connected to the first set of rods 207d. (Refer to the attached figure.) Figure 3 The connection has a limit structure to ensure that the two internal threaded rods 207c can only rotate and will not fall off.

[0061] Preferably, the diameter of the knurled part of the knurled rod 207a is smaller than the outer diameter of the internally threaded rod 207c.

[0062] Preferably, the telescopic roller 208 is composed of a hollow rod 208a and an extension rod 208b, which are movably connected. The ends of the hollow rod 208a and the extension rod 208b are respectively movably connected to a second set of rods 208d. A thin rod 208c is inserted into the hollow rod 208a to form a telescopic roller 208. The telescopic roller 208 can not only press the sheet metal, but also ensure the stability of the parallelogram structure. The telescopic roller 208 is passively adjustable.

[0063] Preferably, the adjusting gear 301 and the transmission gear 302 can mesh. When the transmission gear 302 rotates through the torque tube 302a, the adjusting gear 301 can drive the cam 301a to rotate, thereby lifting the correction plate 205b and deforming the entire parallelogram, thus adjusting the posture of the correction plate 205b and the auxiliary plate 206b. Personnel can insert a steel bar or rod-shaped metal rod into the torque groove 302b to force the transmission gear 302 to rotate. It should be noted that the diameter of the adjusting gear 301 is larger than that of the transmission gear 302, which facilitates fine-tuning of the adjusting gear 301 and provides greater torque.

[0064] Preferably, the bottom of both the correction plate 205b and the auxiliary plate 206b should be fixed with rectangular blocks for limiting their position. Figure 5 Not shown in the diagram, it serves as a guide for the sheet material that needs to be cut. Furthermore, under normal conditions, the telescopic roller 208 and the extension roller 207 should be in close contact with the surface of the worktable 201.

[0065] Preferably, the push rod 403 is fixed on the support wall 401, and the telescopic end of the push rod 403 is fixedly connected to the push plate 402. Therefore, the push rod 403 can push the push plate 402 to move linearly and feed the plate. The balance rod 402a passes through the support wall 401 to balance and limit the push plate 402, ensuring the stability of the feeding process.

[0066] Preferably, the push rod 403 should be an electric push rod.

[0067] In use, by inserting the rod into the torque groove 302b, the transmission gear 302 is turned. The adjusting gear 301 rotates the cam 301a due to meshing. The cam 301a lifts the correction plate 205b. At this time, the correction plate 205b is simultaneously hinged to the extension roller 207 and the telescopic roller 208. The same applies to the auxiliary plate 206b. The correction plate 205b and the auxiliary plate 206b are offset at the same time, so the correction plate 205b and the auxiliary plate 206b can be leveled. Under the action of the return spring 205b-4, the correction plate 205b always pushes against the cam 301a and ensures its stable posture. By placing the locking bolt 303 kit in the gap of the transmission gear 302 and the arc groove 205a-5, and tightening the locking bolt 303, the transmission gear 302 can be locked. Then the cam 301a remains stationary.

[0068] Then, by twisting the knurled rod 207a, under the action of the opposing double threads, the two internal thread rods 207c extend or retract simultaneously, and the corresponding telescopic roller 208 also automatically adjusts to the appropriate length. At this time, the rotating arm 203 rotates synchronously, causing the correction component 205 and the auxiliary component 206 to expand outward or retract inward at the same time, ensuring the width required to guide the board. Finally, the board is placed between the correction component 205 and the auxiliary component 206, and the push rod 403 is activated. The push rod 403 drives the push plate 402 to push the board into the shearing machine.

[0069] In summary, this design can reduce the workload of personnel through automatic feeding, and at the same time, it can adjust the posture of the board after feeding during the cutting process to achieve precise positioning, abandoning the traditional marking method and realizing the function of correcting the posture of the board.
