Description

Technical Field

[0001] This invention relates to the technical field of metal surface treatment, and in particular to a stainless steel surface drawing device and its drawing method. Background Technology

[0002] Stainless steel wire drawing is a metal processing technique and one of the most popular surface treatment technologies in the stainless steel and aluminum products industry today. It is a process that applies a wire drawing effect to stainless steel and aluminum products.

[0003] Stainless steel is typically produced using a brushed finish, except when used in jewelry and handicrafts. During processing, impurities in the stainless steel can oxidize, resulting in a duller color, easier surface scratches, and a more prone-to-staining appearance. Surface brushing is a treatment method that creates linear patterns on the workpiece surface through grinding.

[0004] The existing stainless steel surface drawing devices and methods have the following problems: 1. When drawing stainless steel on both sides, the drawn side needs to be placed on a flat table. When operating on the undrawn side, friction damage will occur to the drawn side; 2. When drawing stainless steel on both sides, the cutting edge applies pressure to the stainless steel surface twice, which can easily cause deformation of the stainless steel plate; 3. The cutting tools of existing straight-line drawing devices are mostly round. When drawing in contact with the workpiece for a long time, the cutting edge is prone to friction heat generation, rolling and wear. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a stainless steel surface drawing device and its drawing method, aiming to solve the problem of how to perform double-sided drawing of stainless steel plates in the prior art, improve the drawing effect while reducing the deformation of stainless steel plates and the cutting edge of the drawing device.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a stainless steel surface drawing device, comprising: a plurality of driving mechanisms and a plurality of lubrication mechanisms and drawing mechanisms connected to the plurality of driving mechanisms.

[0007] The driving mechanism is a screw-slider structure, and the slider in the screw-slider structure is connected to a fixed plate;

[0008] The wire drawing mechanism includes: a motor mounted on the fixed plate and a wire drawing roller connected to the output shaft of the motor. The wire drawing roller is provided with a plurality of main blades and spare blades arranged at intervals, and the blades of the main blades and the spare blades are arranged facing each other.

[0009] The lubrication mechanism includes: a liquid storage tank mounted on the fixed plate and a liquid delivery pipe connected to the liquid storage tank. The liquid delivery pipe is provided with a plurality of nozzles and is positioned above a plurality of the prepared blades.

[0010] The through holes are arranged between the wire drawing mechanisms, and the main knives on both sides of the through holes correspond to each other.

[0011] In a preferred embodiment of the present application, the spray nozzles of the spray heads are trumpet-shaped, and the spray nozzles are downward.

[0012] In a preferred embodiment of the present application, a horizontal positioning unit is further arranged below the liquid storage bin, and the positioning unit comprises a track and a socket arranged in the track.

[0013] In a preferred embodiment of the present application, a bearing is arranged in the socket, and the socket is connected with the track, and the socket is used for mounting the wire drawing roller, and when the size of the through hole is adjusted, the position of the socket is moved and fixed to fix the position of the wire drawing roller.

[0014] In a preferred embodiment of the present application, a plurality of feeding wheels and a plurality of discharging wheels are arranged above and below the wire drawing mechanisms respectively, and the feeding wheels and the discharging wheels are respectively used for feeding the stainless steel workpiece and discharging the stainless steel workpiece.

[0015] In a preferred embodiment of the present application, the driving mechanisms and the wire drawing mechanisms are connected with a control center, and the rotational speed of each motor is controlled by the control center.

[0016] In a preferred embodiment of the present application, a plurality of position sensors are further arranged on the driving mechanisms, and the screw rod in the screw rod and sliding block structure is connected with the driving motor, the moving distance of the wire drawing mechanism is accurately controlled by the position sensor, and the control center is used for control.

[0017] In a preferred embodiment of the present application, a collecting groove is further arranged below the liquid delivery pipe, and the collecting groove is used for collecting the lubricating liquid dripping after spraying, and the length of the collecting groove is same as that of the liquid delivery pipe.

[0018] The present application further provides a wire drawing method of the stainless steel surface wire drawing device, and the method comprises the following steps:

[0019] S1, gap adjustment: according to the thickness of the stainless steel workpiece and the required wire drawing depth, the driving mechanism is controlled to adjust the size of the through hole gap, and then the end of the wire drawing roller is mounted in the socket, and the position of the socket is fixed;

[0020] S2, surface wire drawing: the stainless steel workpiece is positioned through the feeding wheel, the through hole and the discharging wheel, the speed of the feeding wheel and the discharging wheel is adjusted to be same according to the required wire type gap, and the ratio of the motor rotational speed is 1-2:2-5;

[0021] S3, return to the original position: after the surface wire drawing of the stainless steel is completed, the stainless steel workpiece is discharged from the wire drawing device by the discharging wheel, the wire drawing roller is separated from the socket by the driving mechanism, and the whole device returns to the standby state.

[0022] In a preferred embodiment of the present application, before the drawing operation, the motor speed is adjusted using the waste plate, so that the speeds of several motors are the same, and the main knives on the two drawing rollers remain opposite at all times during the operation.

[0023] The present application solves the defects in the background art and has the following beneficial effects:

[0024] (1) In the present application, a plurality of main knives and spare knives are arranged on the two drawing rollers, and their positions are adjusted so that the main knives and spare knives on the two drawing rollers maintain the state of main knife to main knife and spare knife to spare knife during the operation, thereby ensuring that the forces on both sides of the stainless steel plate are counteracted during the drawing process, and the stainless steel plate will not be bent and deformed. This solves the problem that in the prior art, the blade edge exerts pressure on the stainless steel surface twice when double-sided drawing is performed on the stainless steel surface, which easily causes the stainless steel plate to deform.

[0025] (2) The stainless steel plate is simultaneously fed in and out in the vertical direction and subjected to the drawing operation, and both sides are drawn at the same time. The main driving force for the movement of the stainless steel plate is the driving force provided by the feeding wheel. During the drawing process and after the drawing is completed, no part of the device will rub or press against the stainless steel surface, which is prone to damage the surface during drawing. This solves the problem that in the prior art, when double-sided drawing is performed on the stainless steel, the drawn side needs to be placed on a flat table, and when the other side is being operated, the drawn side will be damaged by friction.

[0026] (3) The main knives and spare knives are arranged at intervals, and the blade edges of the two are arranged opposite each other. The main knives and spare knives are used alternately during drawing to avoid long-term friction between the blade edge and the stainless steel surface, which generates heat and high temperature, affecting the drawing effect of the stainless steel surface. A lubricating liquid nozzle is arranged above the spare knife. When the main knife is drawing on the workpiece surface, the spare knife is lubricating at the opposite position. The lubricating liquid can not only reduce the friction between the blade edge and the workpiece surface, but also can cool the blade edge to prevent frictional heat and blade wear.

[0027] (4) The present application also provides a driving mechanism. The drawing mechanism and the lubricating mechanism are installed on the driving mechanism through the fixing plate. The position of the drawing mechanism and the lubricating mechanism is adjusted by the screw block structure in the driving mechanism, so that it can adapt to stainless steel plates of different thicknesses. A positioning unit is arranged below the lubricating mechanism to install the end of the drawing roller, enhancing the structural stability of the overall device during operation. The distance from the drawing mechanism to the stainless steel surface is accurately controlled by the position sensor, and the distance from the blade edge to the stainless steel surface is adjusted by the sensor and the control center, thereby meeting the needs of different depths of drawing.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein. Therefore, the scope of protection of the invention is not limited to the specific embodiments disclosed below.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] like Figure 1 As shown, a three-dimensional structural diagram of a stainless steel surface drawing device is provided, which includes several driving mechanisms and several lubrication mechanisms 10 and drawing mechanisms 4 connected to the driving mechanisms. The driving mechanism is a screw-slider structure, and the slider in the screw-slider structure is connected to a fixed plate 3.

[0037] The wire drawing mechanism and the lubrication mechanism are mounted on the drive mechanism via a fixed plate. The positions of the wire drawing mechanism and the lubrication mechanism are adjusted by the screw and slider structure in the drive mechanism so that it can adapt to stainless steel plates of different thicknesses.

[0038] The wire drawing mechanism 4 includes: a motor 2 mounted on a fixed plate 6 and a wire drawing roller 13 connected to the output shaft of the motor 2. The wire drawing roller 13 is provided with a number of main blades 6 and spare blades 9 spaced apart, and the blades of the main blades 6 and spare blades 9 are arranged facing each other. A through hole 14 is left between the number of wire drawing mechanisms 4, and the number of main blades 6 on both sides of the through hole 14 corresponds one to one.

[0039] This invention sets the main blade and the backup blade at intervals and sets their cutting edges to face away from each other. During wire drawing, the main blade and the backup blade are used alternately to avoid prolonged frictional contact between the cutting edges and the stainless steel surface, which would generate heat and affect the wire drawing effect of the stainless steel surface.

[0040] It should be noted that the main blade is the cutting edge that contacts the workpiece surface during operation, while the spare blade is the cutting edge that will contact the workpiece surface during operation. The cross-sectional shape of the blade is strip-shaped, elliptical, triangular, or square, and the blade thickness is 1mm-5mm.

[0041] By setting several main blades and backup blades on two wire drawing rollers and adjusting their positions, the main blades and backup blades on the two wire drawing rollers maintain a main blade-to-main blade and backup blade-to-back blade state during operation. This ensures that the forces on both sides of the stainless steel plate cancel each other out during the wire drawing process, preventing the stainless steel plate from bending and deforming. This solves the problem in existing technologies where the cutting edge applies pressure to the stainless steel surface twice during double-sided wire drawing, which easily causes the stainless steel plate to deform.

[0042] The lubrication mechanism 10 includes: a liquid storage tank 7 mounted on a fixed plate 3 and a liquid delivery pipe 5 connected to the liquid storage tank 7. The liquid delivery pipe 5 is provided with a plurality of nozzles 8 and is positioned above a plurality of spare blades 9. A collection trough is also provided below the plurality of liquid delivery pipes 5. The collection trough is the same length as the liquid delivery pipe 5. The nozzles of the plurality of nozzles 8 are trumpet-shaped and face downwards.

[0043] Below the liquid storage tank 7, there is also a horizontally positioned positioning unit 11. The positioning unit 11 includes a track 12 and an insertion hole 1 set in the track 12. The insertion hole 1 is equipped with a bearing and is engaged with the track 12. The insertion hole 1 is used to install the wire drawing roller 13. The positioning unit below the lubrication mechanism is used to install the end of the wire drawing roller, which enhances the structural stability of the overall device during operation. The distance between the wire drawing mechanism and the stainless steel surface is precisely controlled by the position sensor. The distance between the cutting edge and the stainless steel surface is adjusted by the sensor and the control center, thereby meeting the needs of wire drawing at different depths.

[0044] A lubricant nozzle is installed above the spare blade. When the main blade is drawing wire on the workpiece surface, the spare blade is lubricated in the opposite position. The lubricant can reduce the friction between the cutting edge and the workpiece surface, and also dissipate heat from the blade to prevent friction heat generation and wear.

[0045] Several drive mechanisms and wire drawing mechanisms 4 are connected to a control center; several position sensors are also provided on several drive mechanisms, and the screw in the screw-slider structure is connected to the drive motor; several feed wheels and feed wheels are respectively provided above and below several wire drawing mechanisms 4.

[0046] The device is configured to feed and discharge stainless steel plates vertically and perform wire drawing operations simultaneously on both sides. The main driving force for the movement of the stainless steel plates is their own weight and the driving force provided by the feeding wheel. During and after the wire drawing process, no parts in the device will rub or squeeze against the stainless steel surface, which could cause damage to the surface. This solves the problem in the existing technology where, when drawing stainless steel on both sides separately, the drawn side needs to be placed on a flat table, and friction damage will occur when operating on the undrawn side.

[0047] like Figure 2 The diagram shows a flow chart of a stainless steel surface drawing device, which provides a method for using the device, including the following steps:

[0048] S1. Gap Adjustment: Based on the thickness of the stainless steel workpiece, the drive mechanism is controlled to adjust the gap size through the hole, and the position sensor accurately ensures the gap size to meet the required wire drawing depth. Then, the end of the wire drawing roller is installed in the insertion hole and the insertion hole position is fixed. The motor is started to drive the wire drawing roller to rotate, and at the same time, the lubrication nozzle sprays lubricant downwards.

[0049] S2, surface drawing: the stainless steel workpiece is put into the drawing device through the feed wheel and the hole, the speed of the feed wheel and the blanking wheel is adjusted according to the required wire type gap of drawing, that is, the distance between two wires caused by the same blade, and the ratio of the motor speed is 1-2:2-5;

[0050] S3, return: the stainless steel plate after drawing operation is led away from the drawing device by the blanking wheel, and the drawing roller is driven by the driving mechanism to separate from the jack, and then the whole device returns to the standby state.

[0051] It should be noted that before the drawing operation, the motor speed is adjusted using the waste plate, so that the speeds of the motors are the same, and the main knives on the two drawing rollers keep relative during the working process.

[0052] The above is based on the ideal embodiment of the application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the application. The technical scope of the application is not limited to the content of the specification, and the technical scope must be determined according to the scope of claims.
