Description

Technical Field

[0001] The utility model relates to the technical field of plate processing and is a corrugating device. Background Art

[0002] Sheet metal corrugation technology originated from the need to optimize material properties. By modifying the surface structure of sheet metal, its mechanical properties and functionality are significantly enhanced. This technology primarily uses galvanized steel and aluminum sheets, creating corrugated sheets with a wavy structure through a cold-bend forming process. The corrugated structure not only increases the sheet's compressive strength and bending resistance, but also makes it lightweight, making it easier to transport and install.

[0003] Chinese patent document with publication number CN117920804A discloses a corrugated board forming mold for a bending machine, which includes an upper mold and a lower mold; the upper mold is composed of a mold handle and a punch, the upper part of the mold handle has the same structure as the upper part of the bending machine tool, the lower part of the mold handle is equipped with a punch, the punch is trapezoidal in shape and embedded in the groove of the mold handle, and the mold handle and the punch are fixedly connected; the lower mold is composed of a lower mold base and a die, the lower mold base is placed in the mold bracket of the bending machine, the upper part of the lower mold base is equipped with a die, the inside of the die is an inverted trapezoidal concave surface that cooperates with the punch, and the lower mold base and the die are fixedly connected.

[0004] The Chinese patent document with the announcement number CN221754461U discloses a corrugated board forming device, which includes a workbench, and the workbench is respectively provided with a conveying mechanism, a hydraulic press, a pushing mechanism and a discharging inclined platform on the four sides, wherein the pushing mechanism and the discharging inclined platform are positioned relative to each other; a pressure plate, which is mounted on the workbench, and has a plurality of spaced concave flutes on the pressure plate; a punching plate, which is mounted on the movable end of the hydraulic press and is located directly above the pressure plate, and the bottom of the punching plate has a plurality of convex flutes corresponding to and matching the concave flutes; a lifting mechanism, which includes a lifting air The lifting mechanism comprises a cylinder, a push plate, a guide column and a plurality of lifting components corresponding to the concave grooves one by one. The lifting cylinder is arranged under the workbench, the push plate is fixed to the movable end of the lifting cylinder, the guide column is fixed to the bottom of the workbench, the push plate is slidably mounted on the guide column, and the lifting component includes a lifting plate and a push rod. The bottom of the concave groove has a clearance gap, the lifting plate slides and abuts against the clearance gap, the rod body of the push rod is slidably inserted into the workbench and the pressure plate, and the two ends of the push rod are respectively fixed to the bottom of the lifting plate and the top of the push plate.

[0005] At present, there are three mainstream corrugated processes. The first is roll forming, which uses multiple sets of rollers to gradually bend flat metal (such as iron sheet, strip steel) into a specific cross-sectional shape (such as corrugated, corrugated, U-shaped groove, etc.). It is suitable for continuous mass production. Its disadvantage is that the roller press needs to be specially customized and the investment in roller molds is relatively large; the second is stamping (hydraulic) forming. Stamping is a processing method that uses molds and punches to apply pressure to metal sheets (such as iron sheet) to cause plastic deformation or separation, thereby obtaining the desired shape (such as corrugated, reinforcing ribs, concave and convex patterns, etc.). It is suitable for continuous mass production. It is used for complex shapes (such as corrugated boards with holes) or ultra-high precision. Its disadvantage is that the mold cost is high and small batches are not economical; the third type is bending forming, which is divided into CNC bending and manual bending. CNC bending can still achieve segmented corrugated forming through reasonable molds and programming, and is suitable for specific scenarios (such as small batch customization, local reinforcement ribs, etc.); manual corrugated bending is a sheet metal processing method that relies entirely on hand tools and skills. It is suitable for extremely small batches, personalized design or maintenance scenarios, but it has low efficiency and poor precision and cannot meet the needs of industrial production. Summary of the Invention

[0006] The utility model provides a corrugating device, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problems of high mold cost and low efficiency in the existing corrugating equipment.

[0007] The technical solution of the utility model is achieved through the following measures: a corrugated paper pressing device, comprising a first base, a first upper arm, a bottom mold and a first driving mechanism, the rear portion of the first base and the rear portion of the first upper arm are hingedly mounted together, the lower side of the first upper arm is provided with an upper groove opening downward, a bottom mold matching the upper groove is fixedly mounted on the upper side of the middle portion of the first base, the height of the bottom mold gradually decreases from front to back, a first driving mechanism is provided on the upper side of the front portion of the first base, which can enable the front portion of the first upper arm to swing up and down, and after the front portion of the first upper arm swings downward, corrugations with a height gradually decreasing from front to back can be pressed on the plate between the bottom mold and the first upper arm.

A second driving mechanism that can make the front part of the second upper arm swing up and down is provided on the upper side of the front of the second base.

[0010] The lower groove may be in a V-shape with its opening facing upward, and the lower portion of the die head may be in a teardrop shape.

[0011] A second support frame can be fixedly installed on the right side of the above-mentioned first base, a first limiting rod is provided on the upper side of the second support frame, a second limiting rod is provided on the upper side of the first support frame, and two third limiting rods are symmetrically hingedly installed on the upper right side of the first support frame corresponding to the right position of the second limiting rod.

[0012] As a preference, a plurality of fixing seats can be fixedly installed at intervals in front and back on the left side of the upper portion of the second base, and an inverted L-shaped first limiting block is installed on the upper side of each fixing seat, and the upper side of the first limiting block is located above the lower mold.

[0013] As another preferred embodiment, a third support frame can be fixedly installed on the left side of the above-mentioned second base, and the upper left side of the third support frame is inclined upward relative to the upper right side, and several second limit blocks are fixedly installed at intervals on the front and rear sides of the upper left side of the third support frame.

[0014] The cross section of the upper groove may be rectangular.

[0015] The first drive mechanism and the second drive mechanism can both be hydraulic cylinders.

[0016] The utility model has a reasonable and compact structure and is easy to use. In the initial state, the first upper arm is hingedly connected to the piston rod of the hydraulic cylinder, and the rear part of the first upper arm is hingedly connected to the hinge ear. An acute angle is formed between the lower side of the first upper arm and the upper side of the bottom mold. The hydraulic cylinder is started, and the piston rod of the hydraulic cylinder is extended to drive the front part of the first upper arm to swing downward, that is, to drive the front end of the first upper arm to press downward.

The punching force is manually controlled to achieve different heights of the corrugated plate before and after. Compared with existing equipment, it has the advantages of low cost, easy mold replacement, low threshold, and is easy for most workers to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0031] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 The positional relationships of front, back, top, bottom, left, and right are described in the layout of the manual. Figure 1The layout direction is determined by the

[0032] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0033] Example 1: As shown in the attached Figures 1 to 3 As shown in Figures 5 to 10, the corrugating device includes a first base 1, a first upper arm 2, a bottom mold 3 and a first driving mechanism 4. The rear part of the first base 1 is hingedly mounted to the rear part of the first upper arm 2. The lower side of the first upper arm 2 is provided with an upper groove 5 opening downward. The bottom mold 3 matching the upper groove 5 is fixedly mounted on the upper middle side of the first base 1. The upper front side of the first base 1 is provided with a first driving mechanism 4 that can make the front part of the first upper arm 2 swing up and down. After the front part of the first upper arm 2 swings downward, corrugations with a height gradually decreasing from front to back can be pressed on the plate between the bottom mold 3 and the first upper arm 2.

[0034] According to requirements, the cross section of the upper groove 5 is rectangular, and the height of the bottom mold 3 gradually decreases from front to back.

[0035] The first upper arm 2 can be made of two 100mm×5mm square tubes welded together from top to bottom, and a steel plate is welded on each side of the two square tubes. This can improve the strength of the first upper arm 2. A number of through holes are spaced apart on the left side of the steel plate. The lower sides of the two steel plates are parallel to the lower side of the square tube below, and there is a gap between the lower sides of the two steel plates and the lower side of the square tube below. The gap can be 5mm, that is, the lower side of the lowest square tube and the steel plates on the left and right sides form an upper groove 5 with a depth of 5mm.

[0036] The first driving mechanism 4 is an existing well-known hydraulic cylinder or air cylinder. In this embodiment, the first driving mechanism 4 is a hydraulic cylinder. The upper end of the cylinder body of the hydraulic cylinder is hingedly installed on the inner side of the upper part of the first base 1, and the lower end of the piston rod of the hydraulic cylinder is hingedly installed on the front part of the square tube above the first upper arm 2. In order to improve the connection strength between the piston rod of the hydraulic cylinder and the square tube, a reinforcing plate can be welded on each of the left and right sides of the two square tube fronts of the first upper arm 2. The reinforcing plate is located in front of the steel plate, and a gap is left between the lower side of the reinforcing plate and the lower side of the front end of the square tube below the first upper arm 2. The gap can be greater than 5 mm, that is, the gap between the lower side of the reinforcing plate and the lower side of the front end of the square tube below the first upper arm 2 is greater than the gap between the lower side of the front end of the steel plate and the lower side of the front end of the square tube below the first upper arm 2.

[0037] There are two 100mm×5mm square tubes welded together from top to bottom on the first base 1. In order to ensure strength, a connecting steel plate is welded on each side of the two square tubes on the first base 1. The connecting steel plate is located behind the reinforcement plate. In this way, after the front part of the first upper arm 2 swings downward, the reinforcement plate is located on the left and right sides of the front of the two square tubes on the first base 1, which can play a guiding role.

[0038] The bottom mold 3 is a sloped steel plate welded to the upper side of the square tube above the first base 1. There are several circular holes that pass through the upper side of the sloped steel plate at intervals. The upper side of the sloped steel plate is an inclined surface with the front part tilted upward relative to the rear part. The upper sides of the two connecting steel plates are parallel to the upper side of the square tube above the first base 1, and there is a distance between the upper sides of the two connecting steel plates and the upper side of the square tube above the first base 1. The distance can be 15mm, and the thickness of the rear end of the sloped steel plate can be 15mm, that is, the upper side of the rear end of the sloped steel plate is flush with the upper side of the connecting steel plate, and the thickness of the front end of the sloped steel plate can be 20mm, that is, the upper side of the front end of the sloped steel plate is 5mm higher than the upper side of the connecting steel plate.

[0039] Hinge ears are welded on the left and right sides of the rear of the two square tubes of the first base 1. The hinge ears and the rear of the first upper arm 2 are hinged and installed together through a pin. The thickness, shape of the slope steel plate and the cross-sectional shape and depth of the upper groove 5 can be adjusted according to the shape of the corrugated plate.

[0040] When the first upper arm 2 and the second upper arm 2 are in contact with each other, the first upper arm 2 and the second upper arm 2 are in contact with each other, and the hydraulic cylinder is pressed downwards.

[0041] The corrugating device of the present application is based on stamping and forming, and a specific mold is made. The punching force is manually controlled to achieve different heights of the corrugated plate before and after. Compared with existing equipment, it has the advantages of low cost, easy mold replacement, low threshold, and is easy for most workers to use.

[0042] The above corrugating device can be further optimized and / or improved according to actual needs:

[0043] Example 2: As an optimization of the above example, as shown in the attached Figure 1 、 4As shown in Figures 7 and 11, a bending mechanism is provided on the left side of the first base 1, and the bending mechanism includes a second base 6, a second upper arm 7 and a second driving mechanism 8. A first support frame 9 is provided between the right side of the second base 6 and the left side of the first base 1. The rear part of the second base 6 is hingedly mounted to the rear part of the second upper arm 7. An upper mold 10 is fixedly mounted on the lower side of the second upper arm 7, and a die head 11 is fixedly mounted on the lower side of the upper mold 10. A lower mold 12 is fixedly mounted on the upper side of the second base 6 corresponding to the position of the upper mold 10, and a lower groove 13 with an upward opening is provided on the upper side of the lower mold 12. A second driving mechanism 8 is provided on the upper side of the front of the second base 6, which can make the front part of the second upper arm 7 swing up and down.

[0044] According to the requirements, the lower groove 13 is V-shaped with the opening upward, the lower part of the die head 11 is teardrop-shaped, and the second driving mechanism 8 and the first driving mechanism 4 are both hydraulic cylinders.

[0045] The second upper arm 7 is composed of two 50mm×5mm square tubes welded together, a fixed steel plate is welded on each side of the rear of the second upper arm 7, the side of the rear of the fixed steel plate is opened and installed with a hinge pin, the hinge pin is rotatably installed with the rear of the second base 6, a lifting steel plate is welded on each side of the front of the second upper arm 7, an optical axis is welded in the middle of the lifting steel plate, the optical axis is hingedly connected to the second drive mechanism 8 (the lower end of the piston rod of the hydraulic cylinder), the lower side of the square tube below the second upper arm 7 is welded to the upper side of the upper mold 10, the upper mold 10 and the die head 11 are integrated together, the cross-section of the upper mold 10 is rectangular, the cross-section of the die head 11 is teardrop-shaped, the outer side of the lower part of the die head 11 is an arc surface opening upward, after the die head 11 presses the upper side of the plate, the bent part of the upper side of the plate can be made into an arc shape, that is, the arc transition on both sides of the bend.

[0046] The second base 6 has two 100mm×5mm square tubes welded together, and a hinged steel plate is welded on each side of the left and right rear parts of the two square tubes of the second base 6. The two fixed steel plate sides at the rear part of the second upper arm 7 are hingedly installed between the two hinged steel plates of the second base 6, so that the second upper arm 7 can be limited to prevent the second upper arm 7 from swinging left and right. The lower side of the lower mold 12 is welded together with the upper side of the square tube above the second base 6.

[0047] When the second upper arm 7 and the second driving mechanism 8 are in operation, the second upper arm 7 and the second driving mechanism 8 are in operation. When the second upper arm 7 and the second driving mechanism 8 are in operation, the second upper arm 7 and the second driving mechanism 8 are in operation. When the second upper arm 7 and the second driving mechanism 8 are in operation, the second upper arm 7 and the second driving mechanism 8 are in operation. When the second upper arm 7 and the second driving mechanism 8 are in operation, the second upper arm 7 and the second driving mechanism 8 are driven to swing downward, that is, the die head 11 is driven to press downward, and the die head 11 squeezes the upper surface of the plate so that the plate is concave in the lower groove 13 to realize the bending operation. A limiting steel plate (located in front of the lower die 12) is welded on each side of the front of the two square tubes of the second upper arm 7. When the lower side of the limiting steel plate contacts the upper side of the second base 6, the second driving mechanism 8 stops moving. At this time, the plate bending operation is completed. The limiting steel plate can protect the plate and the die head 11 when the die head 11 squeezes the plate. When the lower side of the limiting steel plate contacts the upper side of the second base 6, the lower side of the die head 11 and the upper side of the lower die 12 are parallel to each other.

[0049] According to needs, several rollers 22 are installed on the upper side of the first support frame 9 and the second support frame 14 at intervals to rotate left and right, so that the rollers 22 can support the plate and reduce the labor intensity of the operators. Two third limiting rods 17 can also be symmetrically hinged and installed front and back on the upper right side of the first support frame 9 corresponding to the left position of the second limiting rod 16.

[0050] When the left side of the plate moves to the left and leans against the right side of the third limit rod 17 (when in use, the two third limit rods 17 are rotated to the upper side of the first support frame 9), the first driving mechanism 4 drives the first upper arm 2 to press the plate down to press the first corrugation on the plate, and then the first driving mechanism 4 lifts the first upper arm 2 and resets. The left side of the plate continues to move to the left and leans against the right side of the second limit rod 16. The first driving mechanism 4 drives the first upper arm 2 to press the plate down to press the second corrugation on the plate, and then the first driving mechanism 4 lifts the first upper arm 2 and resets. After the plate continues to move to the left, it is moved to the right so that the right side of the plate leans against the left side of the first limit rod 15. The first driving mechanism 4 drives the first upper arm 2 to press the plate down to press the third corrugation on the plate, and then the first driving mechanism 4 lifts the first upper arm 2 and resets. In this way, three corrugations can be pressed on the plate.

[0051] The first limiting rod 15 and the second limiting rod 16 can be fixed to the upper side of the second supporting frame 14 and the upper side of the first supporting frame 9 respectively, or a plurality of pairs of card slots can be arranged at left and right intervals on the upper side of the first supporting frame 9 and the upper side of the second supporting frame 14 (each pair of card slots includes grooves arranged at intervals before and after, and the depth of the groove is less than the height of the limiting rod, and the first limiting rod 15 and the second limiting rod 16 are placed in the corresponding grooves respectively, and the spacing between the card slots and the positions of the card slots can be set according to the spacing between the corrugations. A plurality of pairs of shift rods can also be fixed at left and right intervals on the upper side of the first supporting frame 9 and the upper side of the second supporting frame 14 (each pair of shift rods includes positioning rods arranged at intervals before and after, and the first limiting rod 15 and the second limiting rod 16 are placed on one side of the corresponding positioning rod, and the spacing between the positioning rods and the position of the positioning rods can be set according to the spacing between the corrugations.

[0052] Example 4: As an optimization of the above embodiment, as shown in the attached Figure 4 、 6 As shown, a plurality of fixing seats 18 are fixedly installed at intervals on the front and rear sides of the upper left side of the second base 6 , and an inverted L-shaped first limiting block 19 is installed on the upper side of each fixing seat 18 , and the upper side of the first limiting block 19 is located above the lower mold 12 .

[0053] According to the needs, two fixed seats 18 are fixedly installed at intervals on the front and rear of the upper left side of the second base 6. The left part of the first limit block 19 and the fixed seat 18 are fixed together by bolts with nuts screwed on the ends, which facilitates the disassembly and assembly of the first limit block 19. The upper right sides of all the first limit blocks 19 are in the same vertical plane. In this way, after the left side of the plate moves to the left and leans against the upper right side of the first limit block 19, the second driving mechanism 8 can be started. After the second driving mechanism 8 drives the second upper arm 7 to swing downward, the die head 11 moves to the lower groove 13 to realize the bending of the plate. The distance between the upper right side of the first limit block 19 and the lower groove 13 can be set according to the bending size of the plate.

[0054] Example 5: As an optimization of the above embodiment, as shown in the attached Figure 1 、 5 As shown in Figures 7 to 7, a third support frame 20 is fixedly installed on the left side of the second base 6. The upper left side of the third support frame 20 is tilted upward relative to the upper right side. Several second limit blocks 21 are fixedly installed on the upper left side of the third support frame 20 at intervals in front and back.

[0055] As needed, two second limit blocks 21 are fixedly installed at intervals on the front and rear sides of the left upper portion of the third support frame 20. When the distance between the bending position and the side edge of the sheet is greater than the distance between the right side of the first limit block 19 and the lower groove 13, the first limit block 19 can be rotated or removed, and the sheet can be bent by bringing the left side of the sheet closer to the right side of the second limit block 21. The position of the second limit block 21 can be set accordingly according to the bending position of the sheet.

[0056] The above technical features respectively constitute the various embodiments of the present invention, which have strong adaptability and optimal implementation effects. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
