Description

Technical Field

[0001] The invention relates to the technical field of metal processing machinery manufacturing, in particular to the technical field of flying shears, and specifically to a plate shearing and conveying device. Background Art

[0002] Shearing machines for plates include flying shears, swing shears and plate shears. Among them, flying shears can achieve high-precision synchronous cutting during the continuous movement of plates, significantly improving production efficiency, and are increasingly widely used in shearing processing.

[0003] The roller mechanism uses a rigid roller to directly contact the plate, which has strong synchronization and small transmission position error, meeting the synchronization and accuracy requirements of shearing. Therefore, the flying shears in the prior art mostly use roller conveyor mechanisms. However, after the flying shears using roller conveyor mechanisms cut the plate, the shearing part lacks an independent drive. Figure 9 After the tool cuts the sheet, if the tool moves up directly, the unrolled sheet will hit the sheet during the tool's upward movement, resulting in a knife collision. If the tool continues to move up after horizontal transmission, the sheet lacks independent drive after cutting and is in a relatively static state after cutting, and the tool transmission will cause a knife collision with the sheet after cutting.

[0004] In summary, when the plate is sheared in the prior art, the tool will be damaged due to collision. On the one hand, it will cause deformation of the plate cut or burr proliferation in subsequent cutting. On the other hand, the tool needs to be replaced frequently, resulting in high tool replacement + mechanical correction costs. Summary of the invention

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1, a sheet material chasing and shearing conveying device, including a support frame 1 and a baffle 2. There is a diagonal brace at the bend of the support frame 1, which can ensure the support strength at the top of the support frame 1. A plurality of horizontal positioning rollers 100 are rotatably connected between the support frame 1 and the baffle 2. The plurality of horizontal positioning rollers 100 are designed with unequal spacing. The horizontal positioning rollers 100 are arranged at the position where the tool 11 moves, which can prevent the horizontal positioning rollers 100 from contacting the tool 11. The plurality of horizontal positioning rollers 100 are simultaneously attached to the upper and lower sides of the sheet material to guide and position the sheet material. A vertical positioning roller 200 is rotatably connected to the side of the support frame 1 and the baffle 2 that are close to each other. The vertical positioning roller 200 is used to position the sheet material from both sides; After the sheet material is unrolled, it is conveyed from one end of the support frame 1 close to the vertical positioning roller 200 to the end far from the vertical positioning roller 200.

[0022] Such as Figure 1 , Figure 2 And Figure 3 , a reciprocating mechanism is arranged on the support frame 1. The reciprocating mechanism includes a fixed frame 3, a driving motor 4, a rotating connecting plate 5, and a reciprocating connecting plate 6; Among them, the fixed frame 3 is fixed on the support frame 1, the driving motor 4 is fixed on the top of the fixed frame 3, the output end of the driving motor 4 is fixedly connected to the rotating connecting plate 5, and one end of the rotating connecting plate 5 is rotatably connected to the reciprocating connecting plate 6; One end of the reciprocating connecting plate 6 is rotatably connected to a slider 9. The bottom of the slider 9 is fixedly connected to a hydraulic cylinder 10. The output end of the hydraulic cylinder 10 is fixedly installed with a tool 11 for cutting the sheet material; When the driving motor 4 is started, the driving motor 4 drives the rotating connecting plate 5 to rotate. When the rotating connecting plate 5 drives one end of the reciprocating connecting plate 6 to different positions, the reciprocating connecting plate 6 will pull or push the slider 9 to realize the reciprocating movement of the slider 9. The reciprocating speed of the slider 9 is the same as the conveying speed of the sheet material, so that the hydraulic cylinder 10 and the tool 11 at the bottom of the slider 9 are relatively stationary with respect to the sheet material; The driving motor 4 is a servo motor with adjustable speed, and both the driving motor 4 and the hydraulic cylinder 10 are externally connected to a power supply and are controlled by a PLC control system in the prior art. The tool 11 is installed at the bottom of the hydraulic cylinder 10. The installation method of the tool 11 is in the prior art and is not related to this application, so it will not be elaborated here; An activity groove 101 is opened at the top of the support frame 1. A guide rod 102 is fixedly connected in the activity groove 101. There are two guide rods 102. Both guide rods 102 pass through the slider 9. The guide rod 102 is slidably connected to the slider 9, which can provide support for the slider 9 and ensure that the slider 9 and the hydraulic cylinder 10 fixed at the bottom of the slider 9 can only move horizontally.

[0023] Such as Figure 3 And Figure 8A guide plate 12 is fixedly connected to the bottom of the slider 9, a driving block 13 is slidably connected to the guide plate 12, a driving connecting plate 14 is rotatably connected to the driving block 13, one end of the driving connecting plate 14 is rotatably connected to a movable sleeve 15, a driving connecting rod 131 is fixedly connected between the driving block 13 and the output end of the hydraulic cylinder 10, so that the hydraulic cylinder 10 can also drive the driving block 13 to move up and down when it is extended and retracted, and the driving block 13 pushes or pulls the movable sleeve 15 through the driving connecting plate 14.

[0024] The bottom of the guide plate 12 is fixedly connected to a limit block 121, and the limit block 121 is rotatably connected to a limit roller 122. When the driving block 13 moves upward to pull the driving connecting plate 14, the driving connecting plate 14 can eventually come into contact with the limit roller 122 to ensure that the driving connecting plate 14 is always in an inclined state.

[0025] like Figure 4 , Figure 5 and Figure 6 The movable sleeve 15 is provided with a forward movable pushing mechanism, which includes a fixed frame 16, a threaded sleeve 17, a screw 18, a power rack 19, an adjusting gear 20 and a contact plate 21; Among them, the fixed frame 16 is fixed on the movable sleeve 15, the fixed frame 16 is fixedly connected with a threaded sleeve 17, the threaded sleeve 17 is threadedly connected with a screw 18, the top of the screw 18 is rotatably connected with a power rack 19, the adjustment gear 20 is fixed to the outer surface of the screw 18 and is located above the movable sleeve 15, the bottom of the screw 18 is rotatably connected with a contact plate 21, the bottom of the contact plate 21 is rubber, which can increase the friction between the plate and the screw; When the movable sleeve 15 moves, it can drive the forward movable pushing mechanism to move together, so that the resistance plate 21 can move together with the movable sleeve 15 .

[0026] The bottom of the power rack 19 is fixedly connected with a first limit shaft 192, and the first limit shaft 192 is slidably connected to the fixed frame 16, which can ensure that the power rack 19 can move up and down in the vertical direction without deflection; The top of the abutment plate 21 is fixedly connected with a second limiting shaft 211, and the second limiting shaft 211 is slidably connected to the movable sleeve 15, so as to ensure that the abutment plate 21 can slide up and down in the vertical direction without deflection; like Figure 1 , Figure 3 , Figure 4 and Figure 5 , a first adjustment assembly is provided on the baffle 2, and the first adjustment assembly includes a first fixing plate 22, a first U-shaped rod 23 and a first adjustment rack 24; Among them, the first fixed plate 22 is fixed on the baffle 2, and the first U-shaped rod 23 and the first adjusting rack 24 are fixedly connected to the first fixed plate 22. Both ends of the movable sleeve 15 are fixedly connected with guide sleeves 151. Both ends of the first U-shaped rod 23 pass through the guide sleeves 151. The setting of the guide sleeves 151 makes it easier for the first U-shaped rod 23 to align and pass through the movable sleeve 15, ensuring the horizontal movement of the movable sleeve 15, so that the contact plate 21 can apply sufficient friction to the plate. The first adjusting rack 24 is meshed with the adjusting gear 20. The first adjusting rack 24 is fixed. When the movable sleeve 15 moves, the adjusting gear 20 can rotate under the meshing action of the first adjusting rack 24.

[0027] like Figure 4 , Figure 5 and Figure 6 A transmission mechanism is provided on the support frame 1, and the transmission mechanism includes a first round rod and a second round rod rotatably connected to the support frame 1, and a power gear 25 and a first pulley 26 are fixedly connected to the first round rod, so that the power gear 25 and the first pulley 26 can rotate synchronously, and the power gear 25 is located above the power rack 19, but is not meshed with the power rack 19; A contact portion 191 is provided at one end of the power rack 19, and a second pulley 27 and a driven gear 28 are fixedly connected to the second round rod. The second pulley 27 and the driven gear 28 can rotate synchronously. A transmission belt 29 is provided between the first pulley 26 and the second pulley 27, and the transmission connection is achieved through the transmission belt 29.

[0028] like Figure 4 , Figure 5 and Figure 6 A reverse movable pushing mechanism is provided on the support frame 1, and the reverse movable pushing mechanism includes a pushing roller 30, one end of the pushing roller 30 is rotatably connected to the support frame 1, and the other end is rotatably connected to the baffle 2. A rubber sleeve 31 and a matching gear 32 are fixedly connected to the outer surface of the pushing roller 30. The bottom of the rubber sleeve 31 is in conflict with the top of the plate to increase the friction between the pushing roller 30 and the plate. The matching gear 32 is meshed with the driven gear 28, so that the rotation of the matching gear 32 can drive the driven gear 28 to rotate.

[0029] like Figure 2 and Figure 7 , the hydraulic cylinder 10 is located at a non-central position above the tool 11 and is in a different plane from the second adjustment component, and will not be hindered by the second adjustment component when moving; The second adjustment assembly includes a second fixing plate 33 fixed on the support frame 1, and a second U-shaped rod 34 and a second adjustment rack 35 are fixedly connected to the second fixing plate 33; Similar to the first adjusting mechanism, the second U-shaped rod 34 on the second adjusting assembly can ensure the horizontal movement of the movable sleeve 15 when the movable sleeve 15 moves in the reverse direction. When the movable sleeve 15 moves in the reverse direction, the adjusted gear 20 after moving upward can be engaged with the second adjusting rack 35 to drive the adjusted gear 20 to rotate.

[0030] The working principle of a sheet chasing and shearing conveying device provided by the present invention is as follows: As Figure 1 , Figure 2 , Figure 3 , a reciprocating mechanism including a driving motor 4 drives the slider 9 to reciprocate, the slider 9 drives the hydraulic cylinder 10 to reciprocate, and when the hydraulic cylinder 10 extends, it drives the cutter 11 to move downward ( Figure 3 In the figure is the state where the cutter 11 moves downward to just contact the surface of the sheet), when the hydraulic cylinder 10 extends, it can drive the driving block 13 to move downward through the driving link 131, the driving block 13 pushes the movable sleeve 15 through the driving connecting plate 14, and the abutting plate 21 at the bottom of the movable sleeve 15 abuts against the top of the sheet. At this time, the movement of the abutting plate 21 can push the sheet in the direction away from the cutter 11; After the cutter 11 cuts the sheet, it continues to move downward for a certain distance, and the abutting plate 21 continues to push the sheet, so that the cut sheet is separated from the cutter 11, and a sufficient distance is separated between the sheet and the cutter 11, effectively avoiding knife collision.

[0031] As Figure 4 , Figure 5 And Figure 6 , when the movable sleeve 15 moves in the direction away from the cutter 11, under the action of the first adjusting rack 24, the adjusted gear 20 drives the screw rod 18 to rotate counterclockwise, the screw rod 18 rotates counterclockwise and drives the adjusted gear 20 and the power rack 19 to move upward, the adjusted gear 20 moves upward and is separated from the first adjusting rack 24, and the contact part 191 at one end of the power rack 19 contacts the bottom of the power gear 25, and the screw rod 18 drives the abutting plate 21 to move upward and separate from the surface of the sheet; As Figure 4 , Figure 5 And Figure 6, after the sheet is sheared, the hydraulic cylinder 10 drives the cutter 11 to move upward. The contraction of the hydraulic cylinder 10 can drive the driving block 13 to move upward. The upward movement of the driving block 13 pulls the movable sleeve 15 through the driving connecting plate 14. The movable sleeve 15 moves towards the cutter 11. Since the abutting plate 21 has moved upward and separated from the surface of the sheet, the abutting plate 21 will not exert a thrust on the sheet towards the cutter 11. The movable sleeve 15 drives the power rack 19 to move. Under the action of the power rack 19, the power gear 25 is driven to rotate clockwise. The power gear 25 drives the first pulley 26 to rotate clockwise through a round rod. The first pulley 26 drives the second pulley 27 to rotate clockwise through the transmission belt 29. The second pulley 27 drives the driven gear 28 to rotate clockwise through a round rod. The driven gear 28 drives the mating gear 32 to rotate counterclockwise. The mating gear 32 drives the pushing roller 30 to rotate counterclockwise. The rubber sleeve 31 on the surface of the pushing roller 30 abuts against the surface of the sheet. Under the action of friction, the counterclockwise rotating pushing roller 30 exerts a thrust on the sheet in the direction away from the cutter 11, so that the sheared sheet is further separated from the cutter 11. During the upward and downward movement of the cutter 11, the sheet will be pushed, and a sufficient distance will be separated between the sheet and the cutter 11, so that after the sheet is cut, the reciprocating mechanism continues to drive the cutter 11 to move in the sheet conveying direction (at this time, the cutter 11 will not collide with the sheet).

[0032] As Figures 1-6 , when the cutter 11 moves upward above the sheet, the reciprocating mechanism moves to the maximum stroke and starts to pull the slider 9 in the reverse direction. The slider 9 drives the hydraulic cylinder 10 and the cutter 11 to move in the reverse direction. The hydraulic cylinder 10 continues to contract and drives the driving block 13 to move upward through the connecting rod. The driving block 13 pulls the movable sleeve 15 through the driving connecting plate 14, so that the movable sleeve 15 moves upward after separating from the first U-shaped rod 23. At the same time, it moves horizontally with the slider 9 and the hydraulic cylinder 10; As Figure 2 And Figure 7 , when the hydraulic cylinder 10 moves with the slider 9 to near the second U-shaped rod 34, the hydraulic cylinder 10 completes the contraction and the movable sleeve 15 stops moving upward. At this time, the second U-shaped rod 34 relatively passes through the movable sleeve 15. At the same time, the second adjusting rack 35 drives the meshing adjusting gear 20 to rotate clockwise. The adjusting gear 20 drives the screw rod 18 to move downward. The screw rod 18 drives the power rack 19 and the abutting plate 21 to move downward, so that the power rack 19 and the abutting plate 21 return to their original positions, which is convenient for the next cutting of the sheet and the pushing of the cut sheet.

[0033] Compared with the related technology, a sheet chasing shearing and conveying device provided by the present invention has the following beneficial effects: In the present invention, when the hydraulic cylinder 10 drives the cutter 11 to move downward to cut the sheet material, the hydraulic cylinder 10 synchronously drives the driving block 13 to move downward, and synchronously makes the contact plate 21 push the sheet material, so that the cut sheet material is separated from the cutter 11. When the cutter 11 continues to move along the transmission direction and move upward, the pushing roller 30 rotating counterclockwise applies a thrust to the sheet material in the direction away from the cutter 11, so that the cut sheet material is further separated from the cutter 11. During the downward and upward movement of the cutter 11, the sheet material will be pushed, creating a sufficient distance between the sheet material and the cutter 11, effectively avoiding the collision of the cutter.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
