Description

Technical Field

[0001] This application relates to the technical field of grinding equipment, and more specifically, to a pretreatment device for shearing and grinding stainless steel plates. Background Technology

[0002] The shearing and grinding step is one of the pre-treatment steps in the stainless steel sheet production process. Its main purpose is to remove burrs and flash generated during shearing, as well as weld points and dents left from welding or other processing, thereby improving the surface quality and processing precision of the sheet. It generally includes a deburring mechanism and a grinding mechanism.

[0003] For example, a technical solution described in Chinese utility model patent CN209425209U, entitled "A Grinding Device for Stainless Steel Plate Processing," involves adjusting the spacing between clamping plates using a second cylinder and clamping the stainless steel plate between first rotating rollers. The second rotating rollers are then pressed against the top surface of the stainless steel plate to achieve vertical conveying and fixing of the stainless steel plate. When the stainless steel plate moves to the middle position of the side plate, the first and second deburring wheels can deburr the two surfaces of the stainless steel plate, while the edge grinding wheel grinds the two sides of the stainless steel plate. The edge-grinding stainless steel plate then slides out with the conveyor belt.

[0004] For example, a technical solution described in Chinese utility model patent CN214024920U, entitled "A Deburring Device for Stainless Steel Sheets," includes a workbench, a steel plate fixing device, a moving device, a deburring device, a dust cleaning device, and two lifting devices. The workbench is vertically arranged and has an installation groove. The steel plate fixing device is installed in the installation groove on the workbench and slides with the workbench. Both lifting devices are installed in the installation groove and slide with the workbench. The moving device is located on the top of the workbench. The deburring device is installed on the moving device, and the dust cleaning device is installed on the moving device and located next to the deburring device.

[0005] The former's edge grinding device can be connected to a stainless steel plate shearing production line to perform online and automated grinding of stainless steel plates that have undergone pre-shearing treatment. However, as mentioned in the latter, it suffers from the problem that the stainless steel plate has already moved during grinding, affecting the grinding quality. The latter's deburring equipment can provide stable edge grinding, but it cannot be connected to an online production system. Utility Model Content

[0006] The purpose of this application is to provide a pretreatment device for shearing and grinding stainless steel plates, so as to solve the problem that existing edge grinding devices cannot simultaneously meet the requirements of online grinding and grinding stability. The specific technical solution adopted is as follows:

[0007] A stainless steel plate shearing and grinding pretreatment device includes a conveying mechanism capable of conveying along the x-axis, a deburring mechanism located at the beginning of the conveying mechanism along the y-axis, a fine grinding mechanism located at the end of the conveying mechanism along the y-axis, and an edge grinding mechanism located between the deburring mechanism and the fine grinding mechanism; wherein, the deburring mechanism includes a deburring mechanism frame, an upper deburring roller and a lower deburring roller mounted on the deburring mechanism frame, and two sets of dust removal units cooperating with the upper deburring roller and the lower deburring roller, one set of dust removal units being located obliquely above the upper deburring roller and the other set of dust removal units being located obliquely below the lower deburring roller.

[0008] Preferably, the axes of the deburring roller and the de-burring roller are both arranged along the y-axis and span the conveying mechanism, and both are electric rollers with brushes on their surfaces.

[0009] Preferably, the deburring mechanism frame includes a pair of vertical plates and an upper horizontal plate and a lower horizontal plate connecting the pair of vertical plates. The dust removal unit includes a dust removal air knife disposed through the pair of vertical plates. The dust removal air knife is connected to an external dust removal system, and the suction port of the dust removal air knife faces the deburring roller.

[0010] Preferably, the dust removal air knife is arranged axially along the y-axis.

[0011] Preferably, the upper horizontal plate is bent downward to form an upper air guide plate, and there is an angle of 45 to 50° between the upper air guide plate and the upper horizontal plate; the lower horizontal plate is bent upward to form a lower air guide plate, and there is an angle of 45 to 50° between the lower air guide plate and the lower horizontal plate.

[0012] Preferably, the edge grinding mechanism includes an edge grinding mechanism frame, an edge grinding unit disposed on one side of the conveying mechanism, a roller backing disposed on the other side of the conveying mechanism, and a centering unit suitable for adjusting the distance between the edge grinding unit and the roller backing.

[0013] Preferably, the stainless steel plate shearing and grinding pretreatment device includes two sets of the edge grinding mechanism, and the edge grinding units of the two sets of edge grinding mechanisms are located on different sides of the conveying mechanism.

[0014] Preferably, the centering unit is a centering screw mechanism.

[0015] Preferably, the stainless steel plate shearing and grinding pretreatment device further includes an edge pressing mechanism, which is at least disposed between the deburring mechanism and the edge grinding mechanism.

[0016] Preferably, the edge pressing mechanism includes two sets of pressing units disposed on both sides of the conveying mechanism, and the pressing unit includes an edge pressing mechanism frame, a lower conveying roller group and an upper pressing roller group.

[0017] A stainless steel plate shearing and grinding pretreatment device using the technical solution of this application can quickly recover dust behind the deburring roller by setting up a dust removal unit, which can improve the conveying stability of stainless steel and avoid the problem of skipping caused by dust. When the stainless steel plate can be continuously and stably conveyed on the conveying mechanism, it is beneficial to the stable operation of the subsequent edge grinding mechanism.

[0018] Furthermore, the grinding mechanism adjusts the distance between the grinding unit and the roller backing by centering, which can relatively well prevent the stainless steel plate from moving during the grinding process, improve the conveying stability, and thus improve the stability of the grinding process.

[0019] Furthermore, the edge clamping mechanism can clamp the two sides of the stainless steel plate, improving the stability of conveying and the stability of the edge grinding process. Attached Figure Description

[0027] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Example

[0029] Reference Figures 1-5 The stainless steel plate shearing and grinding pretreatment device shown includes a conveying mechanism 1 capable of conveying along the x-axis direction, a deburring mechanism 2 located at the beginning of the conveying mechanism 1 in the y-axis direction, a fine grinding mechanism 4 located at the end of the conveying mechanism 1 in the y-axis direction, and an edge grinding mechanism 3 located between the deburring mechanism 2 and the fine grinding mechanism 4.

[0030] The conveying mechanism 1 is a powered roller conveyor of the prior art.

[0031] The deburring mechanism 2 includes a deburring mechanism frame 21, an upper deburring roller 22 and a lower deburring roller 23 mounted on the deburring mechanism frame 21, and two sets of dust removal units 24 that cooperate with the upper deburring roller 22 and the lower deburring roller 23.

[0032] Specifically, the deburring mechanism frame 21 includes a pair of upright plates 211 and an upper horizontal plate 212 and a lower horizontal plate 213 welded or screwed to connect the pair of upright plates 211. The deburring rollers 22 and 23 are mounted on the pair of upright plates 211 via bearing seats, such that the axes of the deburring rollers 22 and 23 are both arranged along the y-axis and span the conveying mechanism 1. The deburring rollers 22 and 23 are prior art rollers with brushed surfaces and are driven to rotate by a motor. Preferably, the deburring rollers 22 and 23 are prior art electric rollers with brushed surfaces, which simplifies the structure of the equipment.

[0033] Two sets of dust removal units 24 are arranged vertically, one above the other. One set of dust removal units 24 is located diagonally above the deburring roller 22, and the other set is located diagonally below the deburring roller 23. Each dust removal unit 24 includes a linear dust removal air knife screwed onto a pair of vertical plates 211, with the air knife's axial direction aligned along the y-axis. The air knife's suction port is connected to an external dust removal system (e.g., a cyclone dust removal system), and the suction port faces the deburring roller, for example, at a 45° angle to the horizontal plane towards either the deburring roller 22 or the deburring roller 23.

[0034] By setting up the dust removal unit 24, dust can be quickly recovered behind the deburring rollers 22 and 23, which can improve the conveying stability of stainless steel and avoid the problem of skipping caused by dust. When the stainless steel plate can be continuously and stably conveyed on the conveying mechanism 1, it is beneficial to the stable operation of the rear edge grinding mechanism 3.

[0035] In a preferred embodiment, the upper horizontal plate 212 is bent downwards to form an upper air guide plate 214, with an angle of 45-50° between the upper air guide plate 214 and the upper horizontal plate 212, such as 45° in the figure. The lower horizontal plate 213 is bent upwards to form a lower air guide plate 215, with an angle of 45-50° between the lower air guide plate 215 and the lower horizontal plate 213, such as 45° in the figure. By providing the upper air guide plate 214 and the lower air guide plate 215, the dust removal efficiency of the dust removal unit 24 can be improved, and dust can be prevented from being drawn between the stainless steel plate and the conveying mechanism 1.

[0036] The edge grinding mechanism 3 includes an edge grinding mechanism frame 31, an edge grinding unit 32 disposed on one side of the conveying mechanism 1, a roller backing 33 disposed on the other side of the conveying mechanism 1, and a centering unit 34 suitable for adjusting the distance between the edge grinding unit 32 and the roller backing 33.

[0037] Specifically, the edge grinding mechanism frame 31 is positioned on both sides of the conveying mechanism 1. One side of the frame 31 is used to mount the edge grinding unit 32, while the other side is used to mount the roller support 33. The edge grinding unit 32 includes a grinding wheel 321 (or other prior art edge grinding tools) with its axis arranged vertically, driven by a motor. The edge grinding unit 32 may also include a pair of support rollers 322 positioned on either side of the grinding wheel 321, with their axes also arranged vertically. The roller support 33 consists of a row of rollers arranged along the x-axis, suitable for cooperating with the opposite edge grinding unit 32 to stably complete the edge grinding process. The roller axes are also arranged vertically. The centering unit 34 is a prior art centering screw mechanism.

[0038] Taking the aforementioned existing technologies as an example, cylinders or other structures are often used to press the grinding wheel against the support, or a structure is used where the grinding wheels on both sides are opposed. The former approach, using the grinding wheel as a reference, can cause the stainless steel plate to deviate from its original conveying path when passing the grinding wheel during transport; that is, it may move in the y-axis direction under the push of the support. This affects the stability of the stainless steel plate transport, and consequently, the stability of the edge grinding process. In the latter approach, the grinding wheels on both sides rotate simultaneously. If the rotational speed cannot be adjusted, the stainless steel plate is prone to jumping or other unstable transport situations when passing the grinding wheel, thus affecting the stability of the edge grinding process.

[0039] In the technical solution of this application, the distance between the grinding unit 32 and the roller support 33 is adjusted by centering. In other words, the support is not based on either side, but on the central axis of the conveying mechanism 1. This can better prevent the stainless steel plate from moving during the grinding process, improve the conveying stability, and thus improve the stability of the grinding process.

[0040] In addition, unless only one side of the stainless steel sheet needs to be ground, the stainless steel sheet shearing and grinding pretreatment device generally requires two grinding mechanisms 3, and the grinding units 32 of the two grinding mechanisms 3 are located on different sides of the conveying mechanism 1.

[0041] The structure of the fine grinding mechanism 4 is similar to that of the deburring mechanism 2, the only difference being that the brushes on the walls of the upper and lower fine grinding rollers used for fine grinding are finer and softer. For example, the fine grinding electric roller brush in the prior art.

[0042] In a preferred embodiment, the stainless steel plate shearing and grinding pretreatment device further includes an edge clamping mechanism 5, which is at least disposed between the deburring mechanism 2 and the edge grinding mechanism 3. When there are two sets of edge clamping mechanisms 5, one set of edge clamping mechanisms 5 is disposed between the deburring mechanism 2 and the edge grinding mechanism 3, and the other set is disposed between the edge grinding mechanism 3 and the fine grinding mechanism 4.

[0043] The edge pressing mechanism 5 includes two sets of pressing units located on both sides of the conveying mechanism 1. Each pressing unit includes an edge pressing mechanism frame 51, a lower conveying roller group 52, and an upper pressing roller group 53. To simplify the structure of the device, the lower conveying roller group 52 consists of multiple short conveying rollers arranged along the x-axis. The roller shafts of the short conveying rollers are mounted via the frame of the conveying mechanism 1 and the edge pressing mechanism frame 51. The upper pressing roller group 53 consists of multiple pressing short rollers arranged along the x-axis. The pressing short rollers correspond one-to-one with the conveying short rollers and are pressed against the conveying roller group 52 via structures such as cylinders.

[0044] In this embodiment, the width of the deburring mechanism 2 should be greater than the width of the conveying mechanism 1 but less than the width of the pressing and conveying mechanism formed by a pair of pressing units. By setting the edge pressing mechanism 5, the two sides of the stainless steel plate can be pressed, improving the conveying stability and the stability of the edge grinding process.

[0045] Looking back Figure 1 As shown, the stainless steel plate shearing and grinding pretreatment device provided in this embodiment can be connected to the feeding conveyor 6 and the unloading conveyor 7 to be integrated into the main production line and share a control system. The stainless steel plate enters the deburring mechanism 2 from the feeding conveyor 6, where the upper and lower surfaces are initially deburred. The deburring mechanism 2 can also collect dust. Then it enters the conveying surface formed by the conveying mechanism 2 and the edge pressing mechanism 5, and passes through the edge grinding mechanism 3 under the conveying of the two. The edge grinding mechanism 3 pre-centers according to the width of the stainless steel plate. After the edge grinding is completed, it continues to enter the fine grinding mechanism 5 under the joint conveying of the conveying mechanism 2 and the edge pressing mechanism 5. After the fine grinding is completed, it leaves from the unloading conveyor 7.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this application.
