High-precision metal sheet bidirectional slotter

Abstract

This high-precision bidirectional grooving machine for thin metal sheets includes a base, support sections, columns, guide sections, and a crossbeam. Support sections are located at both ends of the base, and guide sections are mounted on these support sections, with their axial direction perpendicular to the tool holder's movement direction. The columns are slidably mounted on the guide sections, and the crossbeam is supported by two columns. Limiting sections extend to both sides from the top of the base, and limiting blocks are located inside the columns. The limiting sections are adjacent to the limiting blocks and are positioned above the support sections. The adjacent positioning of the limiting sections restricts the upward movement distance of the columns, preventing excessive frame vibration caused by the pressure foot device after guide section wear. This solves the problem of inconsistent grooving depth caused by guide section wear. The motor lead screw is concealed, preventing waste debris generated during grooving from entering the drive screw and reducing its wear.

Description

Technical Field

[0001] This invention relates to the field of stainless steel sheet processing, and more specifically to a high-precision bidirectional grooving machine for thin metal sheets. Background Technology

[0002] In the decoration of shopping malls, airports, restaurants, hotels, banks and other places, a large amount of metal sheets are needed. The metal sheets need to be bent. In order to make the radius of curvature of the bent metal sheets small and the appearance more exquisite, it is necessary to groove the metal sheets before bending.

[0003] Therefore, planing the bending area of ​​the sheet metal—that is, planing a V-groove along the bending line and then bending along the V-groove—can effectively reduce the bending radius of the workpiece, eliminate the outward extension of deformation in the bending area, and ensure that the two sides of the workpiece are flat after bending. This process is widely used in the sheet metal manufacturing and stainless steel decoration manufacturing industries.

[0004] After a period of use, traditional grooving machines experience increased wear at the contact points between the frame and the guide rails due to the frame sliding back and forth along the guide rails for extended periods. When the presser foot device holds the board in place, the reaction force exerted by the presser foot device on the frame causes the frame to float relative to the base. This results in inconsistent grooving depths during the grooving process as the cutter moves across the board. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by proposing a high-precision bidirectional grooving machine for thin metal sheets. The specific technical solution is as follows:

[0006] A high-precision bidirectional grooving machine for thin metal sheets is characterized by comprising a base, a support section, a column, a guide section, and a crossbeam.

[0007] Two support parts are arranged opposite to each other, and the base is located between the two support parts. A guide part is installed on the support part, and the axis of the guide part is perpendicular to the direction of movement of the tool holder.

[0008] The column is slidably mounted on the guide section, and the crossbeam is supported by two columns;

[0009] A hidden area is provided in the space adjacent to the base and the support, and the drive component is hidden in the hidden area. The moving part of the drive component pushes the corresponding column to slide along the guide.

[0010] To better realize the present invention, it can be further described as follows: the top of the base extends to both sides to form a limiting part, a limiting block is provided on the inner side of the column, the limiting part and the limiting block are arranged adjacent to each other, and the limiting part is located above the support part;

[0011] A hidden space is formed between the lower side of the limiting part, the end face of the base, and the upper surface of the support part, and the driving component is disposed in the hidden space.

[0012] Furthermore, a strip-shaped through groove is formed along the length of the side of the crossbeam. An auxiliary beam is positioned between the two columns, also with a strip-shaped through groove formed along the length of the side of the crossbeam.

[0013] When the crossbeam is subjected to the reaction force of the pressure foot device, the strip-shaped channel can distribute the force and prevent the crossbeam from deforming. At the same time, it eliminates the vibration generated on the crossbeam when the pressure foot is pressed down.

[0014] Furthermore, the drive component is a lead screw and nut mechanism.

[0015] Furthermore, a slider is installed at the bottom of the column, which slides in conjunction with the guide portion.

[0016] Furthermore, the limiting part is disposed adjacent to the slider.

[0017] Furthermore, pressure foot devices are provided at both ends of the crossbeam.

[0018] Furthermore, a slide rail is provided along the length direction on the outer side of the crossbeam, the cutter is slidably mounted on the slide rail, and a drive mechanism is provided on the crossbeam, which drives the cutter to slide along the slide rail.

[0019] Furthermore, the drive mechanism adopts a gear and rack mechanism.

[0020] Furthermore, the upper surface of the limiting part and the upper surface of the base are located on the same horizontal plane.

[0021] The beneficial effects of this invention are as follows: First, by providing a strip-shaped through groove along the length of the side of the crossbeam, the crossbeam can distribute the force when subjected to the reaction force of the pressure foot device, thus preventing deformation of the crossbeam. Simultaneously, it eliminates the vibration generated on the crossbeam when the pressure foot is pressed down.

[0022] Secondly, limiting parts are provided on both sides of the top of the base, and the guide part is located below the limiting part. The motor screw is hidden to prevent the waste generated during grooving from entering the transmission screw and to reduce the wear of the transmission screw.

[0023] Meanwhile, the upper surface of the base is a single flat surface, so the waste generated during slotting will not accumulate on the sides, but will fall directly into the waste bins set on both sides.

[0024] Third, the limiting part and the limiting block are arranged adjacent to each other. The limiting part restricts the upward movement distance of the column by limiting the movement of the limiting block, which avoids large frame vibration under the action of the pressure foot device after the guide part wears. This solves the problem of inconsistent groove depth caused by guide part wear and greatly improves the grooving accuracy. Attached Figure Description

[0028] The attached diagram shows the following components: base 1, column 2, support base 3, limit block 4, guide rail 5, crossbeam 6, strip groove 7, limit plate 8, planer assembly 9, drive motor 10, lead screw 11, slider 12, bearing seat 13, slide rail 14, rack 15, drive mechanism 16, presser foot assembly 17, and auxiliary beam 18. Detailed Implementation

[0029] 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.

[0030] like Figure 1 and Figure 2 As shown: This invention provides a high-precision bidirectional grooving machine for thin metal sheets, which includes the following components:

[0031] 1. Base, 2. Column, 3. Support, 4. Limiting block, 5. Guide rail, 6. Crossbeam, 7. Strip groove, 8. Limiting plate, 9. Planer assembly, 14. Slide rail, 15. Rack, 16. Drive mechanism and clamp;

[0032] Limiting plates 8 are formed by extending outward from the two short sides of the upper surface of the base 1. The upper surface of the limiting plate 8 is on the same horizontal plane as the upper surface of the base 1, and the limiting plate 8 and the base 1 are integrally formed.

[0033] Support seats 3 are provided at both ends of the base 1, and clamps are evenly installed on the long side of the upper surface of the base 1.

[0034] A guide rail 5 is installed on the support base 3 along the width direction of the base 1. A column 2 is slidably installed on each guide rail 5. The two columns 2 support the crossbeam 6. A strip-shaped through groove 7 is opened on the crossbeam 6 along the length direction. The crossbeam 6 is a mother-daughter beam structure. It can be integrally formed, with a groove in the crossbeam 6, or the daughter beam can be welded to the mother beam. There is a gap between the daughter beam and the mother beam.

[0035] When subjected to the reaction force of the presser foot device, the strip groove 7 distributes the force, preventing the crossbeam 6 from deforming.

[0036] An auxiliary beam 18 is installed between the two columns. This further improves the stability of the frame, reduces vibration during processing, and improves grooving accuracy.

[0037] Screw and nut mechanisms are installed on the side walls at both ends of the base 1, and the screw and nut mechanisms are located between the limit plate 8 and the support base 3 on the corresponding side.

[0038] The limit plate 8 blocks the lead screw nut mechanism to prevent waste residue from entering the lead screw 11.

[0039] The lead screw and nut mechanism includes a drive motor 10, a lead screw 11, a bearing housing 13, and a nut.

[0040] The drive motor 10 and bearing housing 13 are located at both ends of the guide rail 5. The lead screw 11 is rotatably connected between the drive motor 10 and the bearing housing 13. The nut is sleeved on the lead screw 11 and threadedly engaged with the lead screw 11. The nut is fixedly connected to the column 2. The slider 12 is slidably mounted on the guide rail 5. Each slider 12 is fixedly connected to the bottom of the column 2 on the corresponding side.

[0041] Presser foot assemblies 17 are installed at both ends near the crossbeam 6. These presser foot assemblies 17 are used to fix the workpiece on the base 1.

[0042] A slide rail 14 and a rack 15 are respectively installed along the length of the crossbeam 6. The planer assembly 9 is slidably installed on the slide rail 14. The drive mechanism 16 is fixedly connected to the planer assembly 9. A gear is installed on the rotating end of the drive mechanism 16. The gear meshes with the rack 15. The drive mechanism 16 drives the gear to rotate. The gear rotates on the rack 15, pushing the planer assembly 9 to move along the length of the crossbeam 6.

[0043] When the drive motor 10 drives the lead screw 11 to rotate, the lead screw 11 drives the nut to slide, and the nut drives the slider 12 to slide on the guide rail 5 through the column 2. The crossbeam 6 moves synchronously under the action of the column 2.

[0044] The working principle of this invention is as follows: the plate is placed on the upper surface of the base 1, and a row of clamps on the base 1 clamps the sides of the plate. Two sets of presser foot assemblies 17 press down on the plate to fix it. Under the reaction force, the crossbeam 6 drives the two columns 2 to move upward. Due to the setting of the limit plate 8 and the limit block 4, the upper surface of the limit block 4 is limited by the limit plate 8, and the movement of the columns 2 is kept within the set range. The cutter head of the planer assembly 9 presses down, and the drive mechanism 16 drives the gear to rotate. Under the action of the gear and the rack 15, the drive mechanism 16 drives the planer assembly 9 to move along the slide rail 14. The planer assembly 9 grooves the plate from left to right along the crossbeam 6. When the planer assembly 9 reaches the right end of the crossbeam 6, the planer assembly 9 drives the cutter head to rise. The drive motor 10 drives the lead screw 11 to rotate. The lead screw 11 drives the nut to slide. The nut drives the slider 12 to slide on the guide rail 5 through the column 2. The crossbeam 6 moves synchronously under the action of the column 2.

[0045] Next, the planer assembly 9 grooves the board from right to left along the crossbeam 6, repeating the above process to groove back and forth on the board. Since the crossbeam 6 remains stable, the grooving depth is consistent.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
