Description

Technical Field

[0001] This utility model belongs to the field of shearing and conveying technology, and in particular relates to an anti-rolling shearing feeding device. Background Technology

[0002] Shearing machines are widely used in industries such as metal processing to cut sheet metal to the required dimensions. The feeding device, as a crucial component of the shearing machine, directly affects the shearing quality and processing efficiency of the sheet metal.

[0003] Traditional shearing and feeding devices suffer from several problems during operation. Firstly, they lack effective control over the stability of the sheet material conveying process. During conveying, the sheet material is easily affected by external forces, such as vibrations in the conveying mechanism or uneven feeding speeds, causing it to shift and wobble. This not only affects the accuracy of the shearing dimensions but may also lead to the scrapping of the sheet material. Secondly, and more critically, existing feeding devices struggle to effectively address the issue of edge curling. Due to the inherent characteristics of the material (such as uneven texture and a certain elastic modulus), the edges of the sheet material are highly prone to curling under shearing force. Furthermore, factors such as cutter wear, unreasonable cutter clearance, and insufficient equipment precision exacerbate the curling problem. Curled sheet material not only affects the product's appearance quality but can also hinder subsequent processing steps such as welding and assembly, increasing processing costs and scrap rates.

[0004] Therefore, it is essential to invent an anti-rolling shearing feeding device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anti-rolling shearing feeding device, including a conveying platform, a support frame, a conveying roller group, a ball screw, a conveying drive component, a pushing platform, a mounting base, a tilting drive component, a tilting arm, a tilting pressure plate, and pressure rollers. The conveying platform is fixedly installed on the support frame. Two conveying roller groups are rotatably installed on the conveying platform, and a ball screw is rotatably installed thereon. One end of the ball screw is fixed to the output end of the conveying drive component fixedly installed outside the conveying platform. The ball screw is connected to the pushing platform through a ball nut. Two mounting bases are installed on both sides of the conveying platform. The output end of the tilting drive component fixedly installed on the mounting base is fixed to one end of the tilting arm. The other end of the tilting arm is fixedly connected to the tilting pressure plate. Several pressure rollers are rotatably installed on the tilting pressure plate.

[0006] Preferably, the conveying platform has slots through its sides and middle for installing the conveying roller assembly and ball screw. The ball screw is located between the conveying roller assemblies. The two conveying roller assemblies are arranged in parallel and rotatably installed at the slots on both sides of the conveying platform. The conveying roller assemblies can contact the lower surface of the steel plate material.

[0007] Preferably, the ball nut installed on the ball screw is slidably connected to the slot through the middle of the conveying platform, and the push platform connected to the ball nut is slidably connected to the top of the conveying platform. The conveying platform is located between the two flipping pressure plates and the two conveying roller groups.

[0008] Preferably, the flipping pressure plate has an "H" shaped structure, with notches at both ends for rotating and installing the pressure roller. The pressure roller is located above the conveying roller group, and together they form a rolling conveying channel for the steel plate material, allowing the pressure roller to contact the upper surface of the steel plate material.

[0009] Preferably, the middle of the flipping pressure plate is fixed to the L-shaped flipping arm, and the flipping drive component can drive the flipping pressure plate to move through the flipping arm.

[0010] Preferably, one end of the tilting arm is rotatably mounted on two mounting seats via a shaft, and is fixed to the output end of a tilting drive component fixedly mounted on one of the mounting seats. The mounting seats are arranged in pairs, and there are two sets in total.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model's conveying platform is fixedly mounted on a support frame, providing stable foundation support for the entire feeding process. Two parallel and correspondingly rotating conveying roller sets are installed at the slots on both sides of the conveying platform, allowing them to contact the lower surface of the steel plate material. During conveying, they provide excellent support and guidance, ensuring the stability of the steel plate and reducing offset and swaying caused by unstable conveying. Simultaneously, a ball screw is located between the conveying roller sets and connected to the push platform via ball nuts, powered by the conveying drive components. This structural design makes the feeding process more precise and stable, effectively controlling the feeding speed and distance, improving feeding accuracy, and thus enhancing the shearing quality of the sheet metal.

[0013] The two mounting seats installed on both sides of the conveying platform of this utility model, together with the connected tilting drive component, tilting arm, tilting pressure plate, and pressure roller, constitute an effective anti-rolling structure. The tilting pressure plate has an "H"-shaped structure, with notches at both ends for rotating and mounting the pressure roller. The pressure roller is located above the conveying roller assembly, forming a rolling conveying channel for the steel plate material together with the conveying roller assembly, and the pressure roller can contact the upper surface of the steel plate material. During the feeding process, when the steel plate passes through this conveying channel, the pressure roller applies a certain pressure to the upper surface of the steel plate, forming a clamping force on the plate with the conveying roller assembly below. This effectively suppresses the upward rolling tendency of the plate under shearing force, ensuring that the edge of the plate remains flat during feeding and shearing, greatly improving the shearing quality of the plate and reducing the scrap rate caused by rolling.

[0014] The flipping pressure plate of this invention is fixed in the middle to an L-shaped flipping arm, and the flipping drive component can drive the flipping pressure plate to move through the flipping arm. One end of the flipping arm is rotatably mounted on two mounting seats via a shaft, and is fixed to the output end of the flipping drive component, which is fixedly mounted on one of the mounting seats. This design can prepare for the subsequent placement of new steel plates and prevent the anti-rolling structure from interfering with the subsequent normal top-to-bottom feeding process.

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides an anti-rolling shearing feeding device, comprising a conveying platform 1, a support frame 2, a conveying roller group 3, a ball screw 4, a conveying drive component 5, a pushing platform 6, a mounting base 7, a tilting drive component 8, a tilting arm 9, a tilting pressure plate 10, and pressure rollers 11. The conveying platform 1 is fixedly mounted on the support frame 2. Two conveying roller groups 3 are rotatably mounted on the conveying platform 1, and a ball screw 4 is rotatably mounted thereon. One end of the ball screw 4 is fixed to the output end of the conveying drive component 5 fixedly mounted outside the conveying platform 1. The ball screw 4 is connected to the pushing platform 6 through a ball nut. Two mounting bases 7 are respectively mounted on both sides of the conveying platform 1. The output end of the tilting drive component 8 fixedly mounted on the mounting base 7 is fixed to one end of the tilting arm 9, and the other end of the tilting arm 9 is fixedly connected to the tilting pressure plate 10. Several pressure rollers 11 are rotatably mounted on the tilting pressure plate 10.

[0024] Furthermore, the conveyor platform 1 is made of high-strength aluminum alloy, with slots for installing the conveyor roller assembly 3 and ball screw 4 through its sides and middle. These slots are milled using a high-precision CNC machine tool to ensure dimensional accuracy. Two conveyor roller assemblies 3 are arranged in parallel and rotatably mounted at the slots on both sides of the conveyor platform 1. Each conveyor roller assembly 3 consists of multiple rollers with diameters and lengths adapted to the width of the conveyor platform 1. The roller surfaces are plated with a hard chrome layer to improve wear resistance and reduce the coefficient of friction, allowing them to contact the lower surface of the steel plate material. The ball screw 4 is located between the two conveyor roller assemblies 3. It is a high-precision ground ball screw, fixedly mounted at both ends of the middle slot of the conveyor platform 1 via bearing seats made of cast iron.

[0025] Furthermore, the ball nut mounted on the ball screw 4 is slidably connected to the slot through the middle of the conveyor platform 1. The outer surface of the ball nut is coated with a wear-resistant polytetrafluoroethylene coating to reduce friction with the slot. The push platform 6, connected to the ball nut, is welded from Q235 steel plate. Its bottom is equipped with a linear guide rail, model HGR20, which mates with the upper surface of the conveyor platform 1. The guide rail is fixed to the bottom of the push platform 6 with bolts, allowing the push platform 6 to slide smoothly above the conveyor platform 1. The conveyor platform 1 is located between the two tilting pressure plates 10 and the two conveyor roller groups 3. When the conveyor drive component 5 drives the ball screw 4 to rotate, the ball nut moves along the ball screw 4, thereby driving the push platform 6 to perform feeding operations on the conveyor platform 1.

[0026] Furthermore, the flipping pressure plate 10 has an "H"-shaped structure, made of 45# steel through forging and machining, possessing good strength and rigidity. It has through-holes at both ends for mounting the pressure roller 11; the dimensions of these through-holes are precisely designed to ensure the pressure roller 11 can rotate freely after installation. The pressure roller 11 is a polyurethane-coated wheel with a steel hub inside. This material ensures sufficient rigidity support while allowing for close contact with the upper surface of the steel plate through the elastic coating, reducing damage to the steel plate surface. The pressure roller 11 is located above the conveyor roller group 3, together forming a rolling conveying channel for the steel plate material. During feeding, the pressure roller 11 rotates with the movement of the steel plate, cooperating with the conveyor roller group 3 to achieve stable conveying of the steel plate and prevent edge curling.

[0027] Furthermore, the tilting pressure plate 10 is fixed in the middle to an L-shaped tilting arm 9, which is also made of 45# steel and is firmly connected to the tilting pressure plate 10 by welding. The tilting drive component 8 can drive the tilting pressure plate 10 to move via the tilting arm 9. One end of the tilting arm 9 is rotatably mounted on two mounting seats 7 via a shaft. The shaft is made of stainless steel and a deep groove ball bearing is installed between it and the mounting seat 7 to reduce rotational friction. One end of the shaft is fixed to the output end of the tilting drive component 8, which is fixedly mounted on one of the mounting seats 7. The mounting seats 7 are arranged in pairs, with two sets in total, located on both sides of the conveying platform 1. When the tilting drive component 8 is working, it drives the tilting arm 9 to rotate around the shaft through rotation, thereby realizing the angle adjustment of the tilting pressure plate 10 to achieve the compaction and decompaction of the steel plate material, providing a basis for the subsequent top-to-bottom feeding method.

[0028] The working principle is as follows: The steel plate to be sheared is placed on the conveyor roller group 3, with the lower surface of the steel plate in contact with the rollers of the conveyor roller group 3. The conveyor drive unit 5 is started, driving the ball screw 4 to rotate. The ball nut on the ball screw 4 moves along the axis of the ball screw 4 under threaded transmission. Since the ball nut is connected to the push platform 6, and the linear guide rail (model HGR20) at the bottom of the push platform 6 cooperates with the upper surface of the conveyor platform 1, the push platform 6 can slide smoothly on the conveyor platform 1. During the movement, the push platform 6 pushes the steel plate forward along the conveyor roller group 3, realizing the automatic feeding operation of the steel plate.

[0029] During the steel plate feeding process, the pressure roller 11, located above the conveyor roller group 3, plays a crucial role. The pressure roller 11 is made of polyurethane-coated rubber, and its elastic coating is in close contact with the upper surface of the steel plate. In the rolling conveying channel jointly constructed by the conveyor roller group 3 and the pressure roller 11, the pressure roller 11 rotates as the steel plate moves, forming a clamping force on the steel plate with the conveyor roller group 3. This clamping force effectively suppresses the upward curling tendency of the steel plate under shearing force, keeping its edges flat during steel plate conveying and achieving an anti-curling function.

[0030] When a top-down feeding method is required, the rotating action of the flipping drive component 8 drives the flipping arm 9 to rotate around the shaft, adjusting the angle of the flipping pressure plate 10 according to actual needs. When the flipping pressure plate 10 is in the downward pressing state, the pressure roller 11 further compacts the steel plate, ensuring the stability of the steel plate's position during subsequent feeding. When it is necessary to release the compaction of the steel plate for feeding, the flipping drive component 8 drives the flipping pressure plate 10 to flip upward at a certain angle, causing the pressure roller 11 to disengage from the steel plate, providing space for the top-down feeding operation. After feeding is completed, the flipping pressure plate 10 is adjusted again to reset the pressure roller 11, continuing to convey and prevent the steel plate from curling.

[0031] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
