Description

Technical Field

[0001] The present invention relates to a bilateral automatic beveling device for steel plates, belonging to the technical field of steel plate beveling. Background Art

[0002] After the production of plates, it is necessary to chamfer the edges, such as iron plates, aluminum alloy plates, plastic plates, etc. There are burrs at the edges, and chamfering is required.

[0003] The traditional edge chamfering, that is, the main shaft, belongs to a fixed method. When the steel plate surface is uneven, the chamfers processed will be of different sizes, resulting in the need for secondary rework. The existing methods include scraping knives and handheld edge chamfering machines. Among them, with a corner scraping knife, the plate is fixed, and then the burrs at the corners are repeatedly scraped off by the corner scraping knife to form a chamfered corner.

[0004] There is also a handheld edge chamfering machine tool on the market at present. First, the plate is fixed, and then the electric blade on the handheld edge chamfering machine is brought close to the edge of the plate for edge chamfering operation. However, when the length of the steel plate is too long, it is very difficult for the handheld edge chamfering machine to control the size and angle of the chamfering, and the surface after chamfering is rough and the edge consistency is poor. The operator needs to control the force and angle during use, with a large labor intensity, low production efficiency, and certain safety hazards.

[0005] In view of this situation, our company proposed a utility model patent with the authorization announcement number CN212599180U, which discloses an automatic displacement edge chamfering device that can achieve mobile edge chamfering and meet the needs of automatic edge chamfering. However, at present, generally four-edge chamfering operations are required for plate edge chamfering, so multiple edge chamfering is needed to form the chamfer, which affects the machining efficiency.

[0006] In view of the above defects, our company proposed a utility model patent with the authorization announcement number CN216680551U, which discloses an automatic edge chamfering device. It uses four edge chamfering main shaft groups to achieve edge chamfering for the four edges of the plate, meeting the need for one-time four-edge chamfering. The edge chamfering milling amount is small, and only a certain amount of abutting travel is required to meet the edge chamfering forming requirements. When a larger edge chamfering milling amount is required, that is, bevel forming, at this time, there will be a larger milling amount for bevel forming, and higher requirements are imposed on the conveying position accuracy of the plate and the milling stability.

[0007] When the edge chamfering device increases the cutting amount, it will cause a certain stress deformation to the plate. At the same time, there are interval segments in the running direction of the plate during its conveying, and the plate will have arch deformations, etc., affecting the bevel forming accuracy of the plate. Summary of the Invention

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant invention and not for limiting the invention. Additionally, it should be noted that for the sake of description, only parts related to the relevant invention are shown in the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0034] The present invention provides an automatic double-sided beveling device for steel plates, as Figures 1 to 5 shown, which includes a base main body 1, a fixed beveling base 2 and a moving beveling base 3 arranged at intervals on the base main body 1, a support carrier 4 arranged between the fixed beveling base 2 and the moving beveling base 3, a plurality of support rollers 40 arranged along the linear displacement direction of the steel plate on the support carrier 4, and a beveling main shaft mechanism 5 and a steel plate conveying mechanism 6 are respectively arranged on the fixed beveling base 2 and the moving beveling base 3.

[0035] The steel plate conveying mechanism 6 includes two conveying roller parts 7 arranged at intervals along the running direction of the steel plate, and the beveling forming end 50 of the beveling main shaft mechanism 5 is arranged between the two conveying roller parts 7. The conveying roller part 7 includes a support roller group 71 and a pressing roller group 72 with lifting displacement arranged on the top of the support roller group 71, and at least one support roller in the support roller group 71 is provided with a rotational power source 8.

[0036] The moving beveling base 3 has a horizontal floating adjustment displacement towards the fixed beveling base 2. At least one abutting bearing 30 for abutting against the bevel end face of the steel plate is arranged on the moving beveling base 3, and a plurality of linearly and evenly spaced side stop limit bearings 20 are arranged on the fixed beveling base 2.

[0037] Specific implementation process and principle description:

[0038] Traditional steel plate conveying is realized by a roller conveying mechanism in an automated chamfering device with the utility model patent of our company's authorization announcement number CN216680551U, that is, the steel plate is driven by a plurality of driving rollers arranged at intervals. However, there is a certain degree of freedom between the steel plate and the groove forming end 50, resulting in poor groove forming stability.

[0039] Therefore, in this case, a design is adopted which is supported by a support frame 4 and cooperated with two side conveying rollers 7, so that the transmission of the two sides of the steel plate is relatively stable, and the two spaced conveying rollers 7 are used to stably convey and maintain the two sides of the groove position, so that the middle groove forming end 50 can achieve stable machining alignment with the end wall of the steel plate, and the groove forming is reliable and stable.

[0040] When performing the groove forming operation, the fixed groove base 2 and the movable groove base 3 are first pre-aligned according to the width of the steel plate, so that after the steel plate enters the equipment, its two sides can be clamped and matched by the conveying roller part 7 respectively.

[0041] The steel plate is clamped and conveyed by the conveying roller parts 7 on both sides, that is, after the crimping roller group 72 is crimped toward the supporting roller group 71, its rotating power source 8 drives the supporting roller to rotate, and the steel plates are driven to run synchronously on both sides, and the bottom of the steel plate is supported and conveyed by the supporting roller 40 of the supporting carrier 4.

[0042] The conveying rollers 7 on both sides can respectively clamp and convey the two sides of the groove position of the steel plate, and have relatively reliable conveying stability. One side of the steel plate abuts against a plurality of side stop limit bearings 20 , and the other side abuts against the abutting matching bearing 30 .

[0043] When the width of the steel plate changes, the wall that contacts the abutting and fitting bearing 30 will generate reverse pressure on the abutting and fitting bearing 30. This reverse pressure causes the mobile groove base 3 to produce floating displacement, thereby driving the groove spindle mechanism 5 thereon to move synchronously, that is, the groove spindle mechanism 5 and the abutting and fitting bearing 30 maintain a relatively uniform position. When the steel plate drives the abutting and fitting bearing 30 to move, its groove forming end 50 also maintains a relative fit with the movement, so that the uniform linear forming accuracy of the groove is higher.

[0044] In a specific embodiment, an adjustable displacement carrier 9 with horizontal adjustable displacement is provided on the base body 1, the mobile groove base 3 is arranged between the adjustable displacement carrier and the fixed groove base, and at least one telescopic floating source 10 is provided between the adjustable displacement carrier 9 and the mobile groove base 3.

[0045] Specific implementation process and principle description:

[0046] The adjusting displacement carrier 9 has a horizontal adjusting displacement on the base body 1. Through the telescopic floating source 10, pre-alignment adjustment of the moving bevel base 3 can be achieved, so that the relative interval between the moving bevel base 3 and the fixed bevel base is adapted to the width of the steel plate, and this pre-alignment interval can meet the telescopic stroke adjustment requirements of the telescopic floating source 10.

[0047] When the width of the steel plate changes, such as becoming wider or narrower along the supply direction, the telescopic floating source 10 can maintain the stable demand for the abutting mating bearing 30 to abut against it.

[0048] In a specific embodiment, as Figure 2 and Figure 4 shown, the telescopic floating source 10 is a telescopic cylinder with a pressure regulating function. A relative stroke limiting mechanism 11 is provided between the adjusting displacement carrier and the moving bevel base.

[0049] Specifically, the telescopic cylinder is equipped with a pressure regulating and control device, that is, a pressure holding threshold is set inside it. When the force on the abutting mating bearing 30 causes displacement of the moving bevel base 3, the pressure of the telescopic cylinder changes. By adjusting the intake and exhaust, its pressure stability is satisfied, ensuring that the abutting mating bearing 30 on the moving bevel base 3 abuts against the steel plate reliably and stably, and having characteristics such as high response efficiency.

[0050] The relative stroke limiting mechanism 11 is used to control the variable stroke interval between the moving bevel base 3 and the adjusting displacement carrier 9, so that the telescopic cylinder is within a safe working range.

[0051] In a specific embodiment, a slide rail group 12 is provided on the base body 1. The adjusting displacement carrier, the moving bevel base, and the support carrier are respectively slidably mated on the slide rail group, and the adjusting displacement carrier and the support carrier are respectively provided with position adjustment drive sources.

[0052] Specifically, since there are different width differences in the steel plate, the displacement adjustment of the adjusting displacement carrier meets the pre-alignment and mating position adjustment requirements of the moving bevel base, and the support carrier can achieve centering support, making the steel plate conveying more stable.

[0053] The slide rail group 12 facilitates the guiding and mating of multiple moving seats, and the relative displacement adjustment is convenient and reliable.

[0054] In a specific embodiment, as Figure 5 shown, the steel plate conveying mechanism 6 includes a steel plate pressure stabilizing part 13 located between two conveying roller parts 7 and used for cooperating with the bevel main shaft mechanism 5. The steel plate pressure stabilizing part 13 includes a support wheel group 131 and a pressure stabilizing wheel group 132 with a lifting displacement arranged on the top of the support wheel group 131.

[0055] Specifically, a relatively large milling force is generated between the groove forming end 50 and the steel plate. The support wheel group 131 and the stabilizing wheel group 132 cooperate with each other to make the groove position of the steel plate more stable.

[0056] In a specific embodiment, the pressure stabilizing wheel assembly 132 includes a plurality of pressure wheels 130 with telescopic elastic floating displacement.

[0057] Specifically, the steel plate will also have thickness tolerance, and the bottom supporting surface of the steel plate is the reference surface. Therefore, the support wheel group 131 adopts the equal height setting method to ensure effective support for the steel plate, and the top pressure wheel 130 realizes floating crimping. When the steel plate groove is subjected to force, forces in multiple directions will be generated. The floating displacement pressure wheel 130 can eliminate the vertical force, thereby meeting the requirements of reliable and stable crimping and eliminating certain machining vibrations.

[0058] In a specific embodiment, the groove main shaft mechanism 5 includes a groove main shaft with lifting adjustment displacement and horizontal adjustment displacement.

[0059] Specifically, there is a correlation between the groove forming of the steel plate and the relative position of the groove forming end 50 , and groove forming requirements of different specifications can be achieved through adjustment of displacement in the horizontal direction and the lifting direction.

[0060] In a specific embodiment, a material guide bearing 14 is provided on the supporting roller group 71 of the conveying roller part 7, and the distance between the material guide bearing 14 and the supporting frame is greater than the distance between the abutting matching bearing and the supporting frame.

[0061] Specifically, the guide bearing 14 is used for pre-alignment and adjustment when the steel plate is fed, so as to meet the requirements of pre-alignment and adjustment, and make the movable groove base 3 within the effective adjustment range.

[0062] In addition, during the steel plate transportation process, the bottom support transportation and top pressure maintenance supply are generally adopted. However, the steel plates involved in this case are heavy. In order to make their transportation more stable and reliable, the following methods are adopted: Figure 5 The conveying roller part 7 is designed as shown.

[0063] That is, the rollers in the crimping roller set 72 and the supporting roller set 71 are both in transmission connection with the rotary power source 8 .

[0064] Specifically, several rollers in the supporting roller group 71 are connected to each other through a synchronous belt or a synchronous gear, and the rotary power source 8 is connected to any roller through a synchronous belt or a synchronous gear.

[0065] A number of rollers within the crimping roller set 72 are connected by a timing belt or timing gears for transmission. There is a transmission mechanism on the crimping roller set that is drivingly mated with the rotary power source 8, and the transmission mechanism is drivingly connected to any one of the rollers. More specifically, there is a transmission rod between the transmission mechanism and the rotary power source 8 that is vertically movable and circumferentially locked to meet the torque transmission requirements during the lifting and displacement process of the crimping roller set 72.

[0066] In a specific embodiment, one side of the steel plate abuts against the side stop limit bearing 20, and the other side is in point contact with the abutting and mating bearing 30. In order to make the abutment between the steel plate and the side stop limit bearing 20 more stable, a feeding bearing 14 with floating displacement is designed, and there is a scale for the relative position between the feeding bearing 14 and the moving bevel base 3. The feeding bearing 14 can achieve floating pressing and abutting cooperation with the steel plate during operation, and at the same time, the initial position of the moving bevel base 3 can be adjusted by using the position of the initial pressing and mating.

[0067] In a specific embodiment, as Figure 3 shown, on one side of the feeding end of the base body 1, there is an automatic feeding carrier 15 for the steel plate.

[0068] That is, it can achieve automatic feeding of the steel plate, which has auxiliary conveying power. Generally, the feeding method of conveying support rollers is adopted. It should be noted that sensors for sensing the steel plate are provided on the support roller set 71 or the crimping roller set 72. The sensors are communicatively connected to the rotary power source 8. When the steel plate is conveyed in place, the automatic feeding carrier 15 for the steel plate stops the main power, and the steel plate is supplied by the conveying roller part 7.

[0069] From the above description, it can be found that the present invention meets the requirements of double-sided synchronous bevel forming of the steel plate. The relative position between the side of the steel plate and the bevel main shaft is reliably and stably mated, and the automation forming accuracy is relatively high. It can achieve follow-up and pressure maintaining on one side of the bevel, ensuring the linear uniformity of the steel plate bevel forming and greatly improving the product qualification rate. It has a pre-adjustable follow-up range alignment function, and at the same time, it meets the driving and conveying stability after the steel plate is loaded. It is particularly suitable for the bevel forming of steel plates with certain tolerances, and the qualification rate of the product bevel forming is guaranteed.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
