Technical Field

[0001] This application relates to the field of sheet metal shearing technology, and in particular to an automatic sheet metal shearing device. Background Technology

[0002] With the sustained and rapid growth of my country's economy, the demand for various types of sheet metal is constantly increasing. Shearing machines can cut metal sheets to specific sizes and shapes, making them an indispensable piece of equipment in the metal processing industry.

[0003] Chinese utility model patent CN205733236U discloses a sheet metal shearing device, which includes a frame and a controller, as well as a loading mechanism, a feeding mechanism and a shearing mechanism mounted on the frame. The loading mechanism is movably mounted on the frame and has a gripping part for gripping sheet metal.

The device also includes an output mechanism mounted on the frame adjacent to the shearing mechanism to output the sheet metal cut by the shearing mechanism, and a stacking mechanism located at the end of the output mechanism to receive the sheet metal output by the output mechanism.

[0004] In view of the aforementioned related technologies, this application provides another device capable of automatically shearing sheet metal. Utility Model Content

[0005] To achieve automatic shearing of sheet metal, this application provides an automatic sheet metal shearing device.

[0006] The automatic sheet metal shearing device provided in this application adopts the following technical solution:

[0007] An automatic sheet metal shearing device includes a shearing frame, a feeding mechanism for feeding sheet metal, a conveying mechanism slidably mounted on the shearing frame for moving the sheet metal, and a shearing mechanism disposed on the side of the shearing frame away from the feeding mechanism for shearing the sheet metal.

[0008] The conveying mechanism includes a conveying seat slidably mounted on the shearing frame, a conveying drive component for driving the conveying seat to slide, a clamping assembly disposed on the conveying seat for clamping the sheet metal, and an ejection assembly disposed on the clamping assembly for ejecting the sheet metal.

[0009] By adopting the above technical solution, when using the above shearing equipment, the plate is conveyed to the shearing frame through the feeding mechanism, and then the plate is clamped and fixed by the clamping component. Then the conveying drive is started to move the plate toward the shearing mechanism. After the shearing mechanism completes the shearing, the plate is pushed out of the conveying seat shearing frame by the ejection component to realize the unloading. The modular design of the above mechanisms makes the assembly more convenient, the degree of automation is high, and the shearing efficiency is high.

[0010] Optionally, the feeding mechanism includes a feeding frame disposed on one side of the shearing frame, a feeding frame mounted on the shearing frame, a feeding slide mounted on the feeding frame, a feeding plate mounted on the feeding slide, and a suction cup disposed on the feeding plate for fixing the plate.

[0011] By adopting the above technical solution, the structural composition of the feeding mechanism is disclosed. The feeding slide moves above the feeding frame, and the feeding plate descends downward. The plate to be cut is attracted and fixed by the suction cup. The feeding plate is reset and the plate is transported to the top of the shearing frame. The overall feeding mechanism has a simple structure and is easy to assemble, realizing automatic feeding of the plate.

[0012] Optionally, the top of the shearing frame is provided with at least two sets of support frames for placing the sheet metal. The support frames are arranged along the sheet metal conveying direction, and support rollers for the sheet metal to abut are rotatably mounted on the support frames.

[0013] By adopting the above technical solution, the support frame can provide support for the sheet material. The support rollers on the support frame make the sheet material smoother during conveying by the conveying mechanism and reduce wear on the sheet material.

[0014] Optionally, the two sides of the support frame are also provided with support plates for placing the sheet metal, and the support plates and the support rollers are at the same height.

[0015] By adopting the above technical solution, the support plate is set so that the board is placed on the support plate after it is loaded. The support plate can increase the support area of ​​the board and further improve the support stability.

[0016] Optionally, the clamping assembly includes a clamping bracket disposed on the conveying seat, a first clamping plate disposed at the end of the clamping bracket, a second clamping plate rotatably mounted on the clamping bracket, and a clamping drive for driving the second clamping plate to rotate, wherein a clamping gap for inserting the plate is formed between the first clamping plate and the second clamping plate.

[0017] By adopting the above technical solution, the structural composition of the clamping assembly is disclosed. The conveying seat moves horizontally toward the plate, the plate is inserted into the clamping gap, and then the clamping drive is activated, so that the second clamping plate rotates toward the first clamping plate to achieve clamping of the plate. The clamping assembly has a simple structure and is easy to assemble.

[0018] Optionally, the side wall of the clamping bracket is provided with a touch sensor for controlling the clamping drive. The touch sensor has an elastic component on the side facing the clamping gap. The elastic component includes an elastic bracket, an elastic rod slidably mounted on the elastic bracket, and an elastic element sleeved on the elastic rod. When the plate pushes the elastic rod, causing the elastic rod to move and abut against the touch sensor, the clamping drive is activated.

[0019] By adopting the above technical solution, the touch sensor and elastic component are set up to realize the automatic opening and closing of the clamping drive. When the positioning component pushes the plate to move, the plate pushes the elastic component, so that the elastic rod abuts against the touch sensor and activates the clamping drive, resulting in high overall clamping effect and clamping efficiency.

[0020] Optionally, the ejection assembly includes an ejection plate disposed on the side wall of the clamping bracket and an ejection drive for driving the ejection plate to move, and the shearing mechanism is provided with an ejection clearance groove for moving the ejection plate.

[0021] By adopting the above technical solution, the structural composition of the ejection component is disclosed. The length of the plate gradually decreases with the number of shearings, causing the clamping component to approach the shearing mechanism and be unable to continue sliding. At this time, the clamping drive is reset and the ejection drive is activated to eject the plate from the clamping component. At the same time, the shearing mechanism is ejected to realize the unloading of the plate.

[0022] Optionally, the shearing frame is provided with a positioning component for clamping the sheet metal. The positioning component includes a positioning slider slidably mounted on the end of the shearing frame, a positioning sliding drive for driving the positioning slider to move horizontally, a positioning push rod disposed on the positioning slider, and a positioning rotation drive for driving the positioning push rod to rotate.

[0023] By adopting the above technical solution, after the plate is placed in the support frame, the positioning push rod is rotated first to switch the positioning push rod to a vertical state, so that the positioning push rod exceeds the height of the plate. Then, the positioning sliding drive component moves the positioning push rod toward the conveyor seat, pushing the plate toward the clamping gap, ensuring that the clamping component can clamp and fix the plate.

[0024] Optionally, the shearing mechanism includes a shearing worktable, shearing columns disposed on both sides of the shearing worktable, a shearing crossbeam connecting the two shearing columns, and a shearing punch that is lifted and installed on the shearing crossbeam. The shearing crossbeam is also provided with clamping rods for pressing the plate and guide rollers for guiding the plate to extend into the bottom of the shearing punch.

[0025] By adopting the above technical solution, the structural composition of the shearing mechanism is disclosed. When the sheet metal is conveyed to the underside of the shearing punch under the action of the conveying mechanism, the shearing punch descends under the action of the driving component, so that the stamped sheet metal is sheared and separated. The setting of the clamping rod can improve the stability of the sheet metal during shearing. The setting of the guide roller can ensure that the sheet metal is inserted between the shearing punch and the worktable, thereby improving the shearing efficiency.

[0026] Optionally, it also includes a feeding mechanism for cutting sheet metal, the feeding mechanism including a feeding conveyor belt disposed on the side of the shearing mechanism away from the shearing frame, a feeding conveyor frame disposed at one end of the feeding conveyor belt and a feeding frame disposed at one end of the feeding conveyor frame, and a feeding roller for moving sheet metal is rotatably mounted on the top of the feeding conveyor frame.

[0027] By adopting the above technical solution and setting up the feeding mechanism, automatic feeding of the board material is realized. The overall structure of the feeding mechanism is simple and easy to assemble.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. This application achieves automated shearing of sheet metal by setting up a shearing frame, a feeding mechanism, a conveying mechanism, a shearing mechanism, and an unloading mechanism. The shearing efficiency is high, and the modular design of each mechanism makes assembly simple.

[0030] 2. This application, through the setting of the support frame and support plate, can achieve a supporting effect on the sheet material, ensuring the stability and smoothness of the sheet material during transportation;

[0031] 3. This application ensures that the plate material can be inserted into the clamping gap by setting the positioning component, and at the same time makes the elastic rod and the touch sensor abut against each other, thereby improving the clamping efficiency. Attached Figure Description

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0040] This application discloses an automatic sheet metal cutting device.

[0041] Reference Figure 1 An automatic sheet metal shearing device includes a shearing frame 1, a feeding mechanism 2, a conveying mechanism 3 slidably mounted on the shearing frame 1, a shearing mechanism 4, and a discharging mechanism 5. The sheet metal is fed onto the shearing frame 1 by the feeding mechanism 2, and then conveyed to the shearing mechanism 4 by the conveying mechanism 3. The shearing mechanism 4 shears the sheet metal, and the sheared sheet metal is collected by the discharging mechanism 5.

[0042] Reference Figure 1 and Figure 2 The shearing frame 1 is generally rectangular. The feeding mechanism 2 includes a feeding frame 21 located at one end of the length direction of the shearing frame 1, a feeding frame 22 mounted on the top of the shearing frame 1, a feeding slide 23 slidably mounted on the feeding frame 22, a feeding plate 24 lifted and mounted on the feeding slide 23, and a suction cup 25 fixed to the feeding plate 24 for fixing the plate.

[0043] The loading frame 21 is a metal frame with an open top, and the top surface of the loading frame 21 is height-matched to the shearing frame 1. The top of the loading frame 21 has a loading groove 211 for placing sheet metal, and the sheet metal is stacked and placed in the loading groove 211. The loading frame 22 is a rectangular frame, and its height, length, and width are all greater than those of the shearing frame 1. The two frames are arranged in parallel, and the shearing frame 1 is located at the bottom of the loading frame 22.

[0044] The top of the feeding frame 22 is fixed along its length with a feeding slide rail 221 on which the feeding slide 23 is slidably mounted. The feeding slide 23 slides on the feeding slide rail 221 via a gear belt structure. A lifting drive component for driving the feeding plate 24 to rise and fall is fixedly installed on the top of the feeding slide 23. In this embodiment, the feeding plate 24 is vertically lifted and lowered by a winch 26, which is fixed to the top of the feeding slide 23. Multiple sets of suction cups 25 are evenly arranged on the bottom of the feeding plate 24. The suction cups 25 are vacuum adsorption cups of the prior art.

[0045] Reference Figure 1 and Figure 3 The conveying mechanism 3 includes a conveying seat 31 that is slidably mounted on the top of the shear frame 1, a conveying drive 32 that drives the conveying seat 31 to move horizontally, a clamping assembly 33 fixed to the conveying seat 31, and an ejection assembly 34.

[0046] The conveyor seat 31 is generally rectangular, and its length is adapted to the width of the shearing frame 1. Two sets of conveying rails 11, which cooperate with the conveyor seat 31, are spaced apart along the length of the top of the shearing frame 1. The conveying drive unit 32 is a conventional motor-screw drive, with the motor of the conveying drive unit 32 fixed to the side of the shearing frame 1 near the loading frame 21. The bottom of the conveyor seat 31 has a drive block that cooperates with the screw of the conveying drive unit 32.

[0047] To improve the stability and smooth movement of the sheet metal on the shearing frame 1, support frames 12 are fixed on opposite sides of the conveyor rail 11 of the shearing frame 1, and the support frames 12 are arranged along the length of the shearing frame 1. Several support rollers 121 are evenly spaced along the length of the support frames 12, and the support rollers 121 and the support frames 12 are rotatably coupled. A support plate 13 is also provided on the side of the support frame 12 near the loading frame 21. The support plate 13 is fixed to the shearing frame 1 by bolts, and the top surface of the support plate 13 is flush with the top surface of the support rollers 121, thereby further improving the support stability of the sheet metal after loading onto the shearing frame 1.

[0048] Reference Figure 3 and Figure 4The clamping assembly 33 includes a clamping bracket 331 fixed to the side wall of the conveyor seat 31, a first clamping plate 332 disposed at the end of the clamping bracket 331, a second clamping plate 333 rotatably mounted on the clamping bracket 331, and a clamping drive member 335 for driving the second clamping plate 333 to rotate. The clamping bracket 331 is a horizontally arranged rectangular plate, which is fixed to the side of the conveyor seat 31 away from the loading frame 21 by bolts. The first clamping plate 332 and the second clamping plate 333 are correspondingly arranged, and a clamping gap 3321 for inserting the plate is formed between the two clamping plates.

[0049] The clamping drive component 335 is a prior art push cylinder, with its tail end hinged and fixed to the top of the clamping bracket 331. A connecting rod 334 is hinged to the output end of the clamping drive component 335, and the connecting rod 334 and the second clamping plate 333 are integrally formed. When the output shaft of the clamping drive component 335 extends, it drives the connecting rod 334 to rotate, which in turn drives the second clamping plate 333 to rotate downwards, causing the second clamping plate 333 and the first clamping plate 332 to abut and fit together.

[0050] In this embodiment, two sets of clamping assemblies 33 are spaced apart on the conveyor seat 31. An ejection assembly 34 is disposed on the side wall of the clamping bracket 331, and the ejection assembly 34 includes an ejection plate 341 and an ejection drive member 342. The ejection drive member 342 is a push cylinder, which is horizontally fixed to the clamping bracket 331. The two sets of ejection assemblies 34 are located on corresponding side walls of the clamping bracket 331.

[0051] The clamping bracket 331 is also provided with a touch sensor 336 and an elastic component 337 on the side wall opposite to the ejection assembly 34. The touch sensor 336 is connected to the clamping drive 335. When the end of the touch sensor 336 is touched, it controls the clamping drive 335 to perform a clamping action.

[0052] The elastic component 337 includes an elastic bracket 3373 bolted to the clamping bracket 331, an elastic rod 3371 slidably mounted on the elastic bracket, and an elastic element 3372 sleeved on the elastic rod 3371. The elastic rod 3371 and the touch sensor 336 are at the same height and both extend horizontally. The elastic bracket is U-shaped, and the elastic element 3372 is a spring arranged in the U-shaped groove of the elastic bracket. In the normal state of the elastic element 3372, the touch sensor 336 and the elastic rod 3371 are separated. When the plate is inserted into the clamping gap 3321 and pushes the elastic rod 3371, the elastic rod 3371 abuts against the touch sensor 336, causing the clamping drive 335 to activate.

[0053] The conveyor seat 31 is also provided with a distance sensor 35 between the two clamping components 33. The distance sensor 35 detects the distance between the conveyor seat 31 and the shearing mechanism 4. When the distance between the conveyor seat 31 and the shearing mechanism 4 reaches a predetermined value, the distance sensor 35 stops the conveying of the conveying drive 32 and resets the output shaft of the clamping drive 335 to release the clamping action.

[0054] Reference Figure 3 and Figure 5 The shearing frame 1 has a positioning assembly 36 for clamping the sheet metal on the side near the shearing mechanism 4. The positioning assembly 36 includes a positioning slider 361, a positioning sliding drive 362 for driving the positioning slider 361 to move horizontally, a positioning push rod 363 disposed on the positioning slider 361, and a positioning rotation drive 364 for driving the positioning push rod 363 to rotate.

[0055] The positioning slider 361 is horizontally slidably mounted on the shear frame 1, and the shear frame 1 has a positioning slide rail 14 that cooperates with the positioning slider 361. The positioning sliding drive 362 is a push cylinder fixed to the top of the shear frame 1, and its output shaft is fixed to the side wall of the positioning slider 361.

[0056] The positioning rotation drive 364 is a 90-degree rotary cylinder, which is fixed to the positioning slider 361. The positioning push rod 363 is fixed to the output shaft of the positioning rotation drive 364, and the positioning push rod 363 can be in two states: vertical and horizontal. When the positioning push rod 363 is in the horizontal state, the overall height of the positioning push rod 363 is lower than the top surface height of the shearing frame 1, and it will not affect the conveying of the plate. When the positioning push rod 363 is in the vertical state, the end face height of the positioning push rod 363 is higher than the height of the plate. The positioning sliding drive 362 drives the positioning push rod 363 to move towards the conveying seat 31, so that the plate is inserted into the clamping gap 3321, and at the same time, the elastic rod 3371 is driven to abut against the contact sensor 336.

[0057] The shearing mechanism 4 operates on the same principle as existing shearing equipment, including a shearing worktable 41, shearing columns 42 on both sides of the shearing worktable 41, a shearing crossbeam 43 on top of the shearing columns 42, and a shearing punch 44 mounted on the shearing crossbeam 43. The shearing punch 44 is raised and lowered by a hydraulic cylinder. The shearing worktable 41 has a push-out relief groove 411 into which the push-out plate 341 extends.

[0058] To improve shearing efficiency, multiple sets of clamping rods 441 are spaced apart at the bottom of the shearing punch 44, and the clamping rods 441 are evenly spaced along the width direction of the shearing frame 1. The clamping rods 441 are raised and lowered by pushing a cylinder. An inclined plate 442 is also provided on the side of the shearing punch 44 facing the shearing frame 1, and the inclined plate 442 is fixed to the shearing punch 44 by bolts. The inclined plate 442 is inclined towards the bottom surface of the shearing punch 44, and multiple guide rollers 443 are spaced apart along the length direction on its two side walls. The guide rollers 443 are rotatably mounted on the inclined plate 442 by bearings.

[0059] Reference Figure 6 The unloading mechanism 5 is located on the side of the shearing mechanism 4 away from the shearing frame 1. The unloading mechanism 5 includes two sets of unloading conveyor belts 51 for conveying sheet metal, an unloading conveyor frame 52 that is lifted and positioned at one end of the unloading conveyor belts 51, and an unloading frame 53 located at the end of the unloading conveyor frame 52. The length direction of the unloading conveyor belts 51 is consistent with the length direction of the shearing frame 1. The unloading conveyor frame 52 is a rectangular frame perpendicular to the unloading conveyor belts 51, and multiple sets of unloading rollers 521 are spaced apart along its length on the top of the unloading conveyor frame 52. A lifting cylinder for lifting is provided at the bottom of the unloading conveyor frame 52. A rotary motor is provided on the unloading conveyor frame 52 to drive one set of unloading rollers 521 to rotate. In the normal state of the lifting cylinder, the height of the unloading conveyor frame 52 is flush with the unloading conveyor belts 51. When a sheet metal is placed on the top of the unloading conveyor frame 52, the lifting cylinder drives the unloading conveyor frame 52 to rise and starts the rotary motor to convey the sheet metal to the unloading frame 53. The structure of the unloading frame 53 is the same as that of the loading frame 21, and it is used to store the cut boards.

[0060] The implementation principle of an automatic sheet metal shearing device according to an embodiment of this application is as follows: the feeding plate 24 conveys the sheet metal from the feeding frame 21 to the top of the shearing frame 1, which is supported by the support frame 12 and the support plate 13; the positioning component 36 is activated to push the sheet metal toward the clamping gap 3321, so that one end of the sheet metal is located in the clamping gap 3321, and at the same time, the elastic rod 3371 abuts against the contact sensor 336, so that the clamping drive component 335 realizes the clamping action; the conveying seat 31 drives the sheet metal to move toward the shearing mechanism 4, the shearing punch 44 cuts the sheet metal evenly, and the sheared sheet metal is collected in the unloading frame 53 through the unloading conveyor belt 51 and the unloading conveyor frame 52.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
