Description

Technical Field

[0001] The invention relates to the field related to power tower processing, and in particular to a bending forming device and method for processing iron components of a power tower. Background Art

[0002] Power towers are tall steel structures, amorphous products. Designers can design the tower frame according to different project conditions. The tower frame has a wide range of uses, mainly used for supporting factory chimneys, large building supports, water tower frames, monitoring projects, communication projects and other special purposes.

[0003] The power tower is formed by splicing and fixing metal parts to form a tower body, and the tower plate parts are bent to improve their strength. In this regard, a plate bending machine for plate processing is disclosed, with announcement number: CN116967318B.

[0004] This bending machine is also a common bending equipment on the market. Similar bending equipment has the following shortcomings and is therefore not suitable for the processing of power tower iron frames:

[0005] Such bending equipment requires holding the plate for bending, and a single power tower requires a large amount of steel frame. The efficiency of processing in this way is far lower, and the work intensity of the relevant staff is also relatively high;

[0006] This type of bending equipment processes the cut plates. The cutting and transportation after cutting both take a certain amount of time, which affects the processing efficiency to a certain extent. Usually the raw material of the power tower is steel coil, and the process of cutting-transporting-bending is relatively cumbersome.

[0007] Usually, the plate is deformed and bent by punching the designated position with a bending tool. The steel frame of the power tower is used for support, and its rigidity is relatively high. When bending, notches need to be opened on the plate to make it locally thinner so that it will not break when bending. This process is mostly done by a separate mechanism, which increases the processing steps to a certain extent and reduces production capacity. Summary of the invention

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0053] For example, see Figures 1 to 10 A bending and forming device for processing iron components of a power tower, comprising a base 3 and a support plate 6 fixed on the base 3 by a support rod 4, a bending member 7 is installed between the base 3 and the support plate 6 through the support plate 6 so as to be liftable, a bending groove 8 cooperating with the bending member 7 is opened on the base 3, and a material stripping assembly is installed in the bending groove 8;

[0054] A feeding table 40 is fixed to one side of the base 3, and a feeding assembly is installed on the feeding table 40. Receiver plates 19 are fixed on both sides of the base 3. Adjustment assemblies are arranged on the two receiver plates 19, and cutting assemblies are integrated on the adjustment assemblies. The adjustment assemblies cooperate with the feeding assemblies in one direction.

[0055] In the embodiment of the present invention, the material sheet 1 is placed on the feeding table 40, so that the material sheet 1 is on the feeding assembly, and the material sheet 1 is transported to the specified bending position by the feeding assembly, and then the hydraulic rod 5 is driven to work, and when the hydraulic rod 5 works, the bending member 7 is driven to stand upright and descend until the bending member 7 abuts against the material sheet 1, and then the adjusting assembly and the cutting assembly work, and while cutting the material sheet 1, a tiny notch required for bending is cut on the material sheet 1. After the adjustment assembly and the cutting assembly work, the bending member 7 is continued to be driven to stand upright and descend by the hydraulic rod 5. At this time, the material sheet 1 has been cut into a specified width, and a tiny notch required for bending already exists at the bending position. The material sheet 1 is bent by descending the bending member 7 and cooperating with the base 3 and the bending groove 8;

[0056] When the sheet 1 is bent, the material stripping assembly is also triggered to work, so that the sheet 1 does not contact the bending groove 8 after being bent, and the friction force of the sheet 1 after being bent when moving along the length direction is reduced, so that the sheet 1 is easier to strip after being bent;

[0057] The present invention makes a part of an automatic production line, in which the material sheet 1 is conveyed to a feeding table 40 through a material discharge device, and the material sheet 1 is wound onto a material roller, that is, a common steel coil, and a punching device is installed on the feeding table 40. The punching, cutting and bending of the material sheet 1 are completed through the production line. The present application integrates bending and cutting into one device to improve processing efficiency and automation.

[0058] Embodiment 2: The difference from Embodiment 1 is that: the adjustment assembly includes receiving plates 19 fixed to both sides of the base 3, and movable plates 21 and limit plates 20 are slidably mounted on the two receiving plates 19, and the cutting assembly is mounted on the movable plates 21; guide blocks 34 are fixed to the bottom of the movable plates 21 and the limit plates 20, and the guide blocks 34 are slidably matched with guide grooves 35 provided on the receiving plates 19;

[0059] The two receiving plates 19 are both rotatably mounted with bidirectional screw rods 18, and both ends of the bidirectional screw rods 18 are sleeved with threaded sleeves 36 that are threadedly matched therewith, and the two threaded sleeves 36 respectively penetrate the limit plate 20 and the movable plate 21 and are fixed to the movable plate 21 and the limit plate 20, and the two bidirectional screw rods 18 are connected by a second transmission chain 27;

[0060] See also Figure 5 A cavity is defined in the base 3, the second transmission chain 27 is in the cavity, a guide roller 28 for limiting the second transmission chain 27 is rotatably installed in the cavity, and an active roller connected to the second transmission chain 27 is rotatably installed in the cavity, a second motor 42 is fixed on the side of the base 3 away from the feeding platform 40, and the second motor 42 is coaxially fixed with the active roller.

[0061] In the embodiment of the present invention, when the second motor 42 is working, the output shaft drives the active roller to rotate, and when the active roller rotates, the second transmission chain 27 drives the two bidirectional screws 18 to rotate synchronously, so that the movable plate 21 and the limit plate 20 are driven to move relative to each other / to move oppositely through the threaded cooperation between the bidirectional screw 18 and the threaded sleeve 36;

[0062] The limiting plate 20 is used to limit the material plate 1. When the material plate 1 is conveyed by the feeding assembly to abut against the limiting plate 20, and the cutting assembly is located on the movable plate 21, when the material plate 1 is cut by the cutting assembly, the center position of the cut material plate 1 is located directly below the bending part 7;

[0063] Since the movable plate 21 and the limiting plate 20 can move relative to / opposite to each other, the width of the sheet 1 before bending (after cutting) can be adjusted.

[0064] Embodiment 3: The distinguishing feature from Embodiment 1 or / embodiment 2 is that: the cutting assembly comprises two lifting blocks 23, and a lifting block 38 is fixed at the bottom of the two lifting blocks 23, and the lifting blocks 23 are slidably matched with the lifting slots 39 provided on the movable plate 21 through the lifting blocks 38;

[0065] A spring 31 is fixed on one side of the two lifting blocks 23, and an electric slider 24 is slidably mounted on the spring 31. A first motor 25 is fixed on the side of the electric slider 24 away from the base 3. The output shaft of the first motor 25 passes through the electric slider 24, and a cutting disc 26 is coaxially fixed on the output shaft of the first motor 25.

[0066] Lifting components are installed on opposite sides of the two lifting blocks 23, and the lifting components cooperate with the adjusting components.

[0067] In the embodiment of the present invention, after the feeding assembly conveys the material sheet 1 to the bottom of the bending member 7, the bending member 7 is driven down to abut against the material sheet 1, and the material sheet 1 is positioned by the abutment between the bending member 7 and the material sheet 1;

[0068] After the bending member 7 abuts against the sheet 1, the electric slider 24 slides along the electric slide rail 41, and the cutting disc 26 is driven to rotate by the working first motor 25, and then the sheet 1 is cut by the cutting disc 26. After the electric slider 24 moves to the end of the stroke, the adjustment component is driven to work, and the movable plate 21 and the limit plate 20 are driven to move in opposite directions, so as to drive the movable plate 21 to move in the direction away from the base 3. At the end of the stroke moving in this direction, it is the center of the next piece that has not been cut. In this process, the lifting block 23 is driven to rise by the lifting component. At this time, the height of the cutting disc 26 can only cut a tiny notch on the sheet 1 when cutting the sheet 1. When the electric slider 24 moves back and forth, a small notch is cut on the sheet 1. The small notch is shown by a dotted line in the sheet 1 in the drawing;

[0069] The travel start and end of the electric slider 24 are both equipped with travel switches, and the adjustment components are driven by the travel switches;

[0070] See also Fig. 9 , wherein the function of the small notch is to make the bending point be located at the position of the small notch during the bending process;

[0071] The point where the sheet 1 is subjected to force when bending is the position indicated by the arrow in the figure. Of course, other positions are also subjected to force. The three points indicated in the figure are the positions subjected to the greatest force. Since the thickness of the sheet 1 is the same, the three points may all experience a certain degree of deformation during the initial deformation process of bending. A small notch is opened at the center position of the sheet 1 to reduce the thickness of the sheet 1 at the small notch position, thereby reducing the force required for the bending deformation. The bending point will appear at this position, and some metal materials may break when bending. By opening a small notch, a certain degree of improvement can be achieved.

[0072] The lifting assembly includes a bracket 2 mounted on the feeding platform 40, and adjustment slots 9 are provided on both sides of the bracket 2. Adjustment blocks 22 are slidably installed in the adjustment slots 9, and the adjustment blocks 22 are connected to the lifting blocks 23;

[0073] Wherein, the adjustment slot 9 is arranged obliquely.

[0074] In the embodiment of the present invention, when the electric slider 24 moves to the end of the stroke, the two-way screw rod 18 rotates and cooperates with the threaded sleeve 36 to drive the movable plate 21 to move in the direction away from the limit plate 20, thereby driving the lifting block 23 to follow the movement. Since the adjustment slot 9 is inclined, the lifting block 23 is raised to a certain extent. When the lifting block 23 is on, it drives the electric slide rail 41, the electric slider 24, the first motor 25, and the cutting disc 26 to follow the rise;

[0075] The sliding cooperation between the lifting block 38 and the lifting slot 39 serves to limit and guide the lifting block 23 .

[0076] The feeding assembly includes two groups of rollers 10 rotatably mounted on the feeding platform 40, the two groups of rollers 10 are coaxially fixed between the two rollers 10 by a transmission rod 11, and two output rollers 15 are rotatably mounted at the bottom of the feeding platform 40, and the output rollers 15 are connected to the transmission rod 11 by a first transmission chain 13;

[0077] The feeding platform 40 is also rotatably mounted with a first limiting roller 14 for limiting and guiding the first transmission chain 13;

[0078] One of the output rollers 15 is connected to the movable plate 21 via a one-way transmission assembly.

[0079] In the embodiment of the present invention, when the cutting assembly and the adjusting assembly are working, the movable plate 21 is driven to perform a reciprocating motion. During the reciprocating motion of the movable plate 21, one of the output rollers 15 is driven to rotate through the one-way transmission assembly. When one of the output rollers 15 rotates, the transmission rod 11 is driven to rotate through the first transmission chain 13, thereby causing the two groups of rollers 10 to rotate in the same direction to transport the material plate 1 for a certain distance.

[0080] The material sheet 1 is located on a roller 10 . In order to prevent the roller 10 from damaging the material sheet 1 when rolling, a rubber layer is provided on the surface of the roller 10 .

[0081] The one-way transmission assembly includes a ratchet wheel 32 coaxially fixed on one of the output rollers 15 , and the ratchet wheel 32 is unidirectionally matched with a ratchet plate 33 fixed on the movable plate 21 .

[0082] Furthermore, when the movable plate 21 moves toward the ratchet wheel 32, the ratchet plate 33 is driven to follow the movement. At this time, the ratchet plate 33 does not have a transmission relationship with the ratchet wheel 32. When the movable plate 21 is reset, the ratchet wheel 32 is driven to rotate through the ratchet plate 33. When the ratchet wheel 32 rotates, the output roller 15 is driven to rotate.

[0083] Wherein, the ratchet wheel 32 is mounted on an output roller 15 close to the base 3;

[0084] It should also be noted that the pawl plate 33 and the ratchet 32 ​​in this embodiment are the application of the ratchet mechanism in the prior art. Since the ratchet mechanism is a relatively mature prior art, it will not be elaborated on here.

[0085] A plurality of baffles 12 are fixed on both sides of the feeding platform 40 .

[0086] In the embodiment of the present invention, the baffle plate 12 can be used to limit and guide the material sheet 1 so that the material sheet 1 is transported along a designated path;

[0087] Embodiment 4: The distinguishing features from Embodiment 3 are as follows: As an additional feature of this embodiment: the baffles 12 on the feeding platform 40 are relatively slidably mounted on the feeding platform 40, and the two baffles 12 are connected by a double-axis cylinder, and the double-axis cylinder is driven to drive the two baffles 12 to move relative / oppositely to adjust the distance of the limit guide to cope with material plates 1 of different widths. This additional feature is not shown in the figure;

[0088] The dual-axis cylinder in this embodiment can be replaced by other equivalent structures, and any structure that can achieve relative / opposite movement of the two baffles 12 is acceptable.

[0089] The material stripping assembly includes a plurality of movable grooves 37 opened in the bending groove 8, and the plurality of movable grooves 37 are arranged in a mirror image;

[0090] A stripping plate 29 is slidably installed in the movable groove 37, a spring 31 is fixed to the bottom of the stripping plate 29, and one end of the spring 31 away from the stripping plate 29 is fixed to the bottom of the movable groove 37;

[0091] The top of the stripping plate 29 is provided with an inclined surface, and a plurality of balls 30 are rollingly mounted on the inclined surface;

[0092] A material-removing arm 17 is slidably mounted on the bracket 2 . The material-removing arm 17 is arranged in an arc shape and extends into the bending groove 8 . The material-removing arm 17 is driven by a cylinder, which is not shown in the figure.

[0093] In the embodiment of the present invention, the stripper plate 29 slightly extends out of the movable groove 37 in the initial state. When the sheet 1 is bent, the stripper plate 29 is driven to retract into the movable groove 37 by the sheet 1, and the spring 31 is compressed at the same time, so that the spring 31 reserves a certain amount of elastic potential energy. After the sheet 1 is bent, when the force applied to the sheet 1 disappears, the stripper plate 29 is driven to rise by the elastic potential energy stored in the movable groove 37 to lift the bent sheet 1.

[0094] The bent sheet 1 is on the ball 30 , which can greatly reduce the friction of the sheet 1 moving in the length direction. The bent sheet 1 can be easily pushed out by driving the ejection arm 17 through the cylinder.

[0095] A controller 16 is fixed on the bracket 2 , and the second motor 42 and the first motor 25 are electrically connected to the controller 16 .

[0096] In the embodiment of the present invention, the cylinder, travel switch and other related electronic components in the embodiment are all electrically connected to the controller 16, and the controller 16 is electrically connected to the computer.

[0097] In summary: the present application realizes the conveying and cutting of the material plate 1 by the mutual cooperation of the feeding component and the cutting component, so that the device can directly use the steel coil for feeding, eliminating the cutting process, and improving the processing efficiency to a certain extent;

[0098] Among them, through the cooperation of the cutting component and the adjusting component, a small notch is opened on a plate to be cut later while the plate 1 is cut. The feeding, cutting, small notch opening and bending can be completed completely automatically by the device without manual assistance. The degree of automation is relatively high. Multiple processing steps are integrated on the device and realized by a relatively simple structure, so the practicability is relatively high.

[0099] Secondly, after the material sheet 1 is bent, the material sheet 1 can be automatically pushed out of the bending groove 8 to enter the subsequent processing steps through the material return component, thereby further improving the automation level of the device.

[0100] The present invention also provides a bending and forming method for processing an iron component of an electric power tower. The bending and forming method for processing an iron component of an electric power tower adopts the bending and forming device for processing an iron component of an electric power tower, and comprises the following steps:

[0101] Step 1: Place the material plate 1 on the feeding assembly;

[0102] Step 2: Use the hydraulic rod 5 to drive the bending part 7 down until the bending part 7 abuts against the sheet 1, and then adjust the assembly and the cutting assembly to work;

[0103] Step 3: Cut the sheet 1 by adjusting the assembly and the cutting assembly, and open a small notch at the center of the sheet 1 to be cut;

[0104] Step 4: The hydraulic rod 5 is used to drive the bending member 7 to continue to descend, and the cut sheet 1 is bent, and the material stripping assembly is also driven to work during the bending process;

[0105] Step 5: After the bending process is completed, the bent sheet 1 is pushed out of the bending groove 8 by the material stripping assembly to complete the bending forming process.
