Description

Technical Field

[0001] This utility model relates to the field of bending equipment, and in particular to a bending machine and bending center. Background Technology

[0002] A bending machine is a machine that can bend thin plates. It is widely used in many industries such as metal processing, home appliances, construction, electronics and automobiles to achieve precise and efficient bending processing of metal sheets.

[0003] The prior art, with publication number CN110538899B, discloses a multi-axis driven bending machine, including a bending system and an integrated loading and unloading system; the bending system includes a horizontal bending drive device, on which a horizontally oriented horizontal bending shaft is mounted; a linkage bracket is mounted on the horizontal bending shaft; and an upper and lower bending drive device is also provided at the upper end of the linkage bracket.

[0004] In existing technologies, bending is generally achieved by interpolating the X and Y axes to create an arc. This method requires high software control and involves complex algorithms. Furthermore, the bending blade in existing technologies is spherical, resulting in line contact with the product during bending. This small contact area affects the straightness and bending arc of the product during the forming process, making the bent product prone to bulges. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bending machine to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution:

[0007] A bending machine includes a frame and a feeding mechanism, and further includes:

[0008] A clamping mechanism is located at the feed inlet of the frame;

[0009] The Y-axis control assembly is mounted on both sides of the frame;

[0010] A bending control assembly is connected to the movable end of the Y-axis control assembly. The bending control assembly includes a lower bending unit and an upper bending unit, which are arranged vertically and vertically, and are set at the feed inlet position through the Y-axis control assembly so that the sheet material to be processed is located between the lower bending unit and the upper bending unit.

[0011] Both the lower bending unit and the upper bending unit include a rotary drive and a bending knife. During bending, the rotary drive drives the bending knife to rotate along the central axis of the rotary drive, completing the bending process of the sheet metal in one go.

[0012] Beneficial effects: The upward and downward bending of the board is completed by using the Y-axis control component to drive the corresponding downward bending unit and upward bending unit. During the upward bending, the Y-axis control component 3 drives the bending control component 4 to move upward until the upward bending unit 42 corresponds to the bending point of the board and performs the upward bending process. During the downward bending, the Y-axis control component 3 drives the bending control component 4 to move downward until the downward bending unit 41 corresponds to the bending point of the board and performs the upward bending process. This greatly improves the switching efficiency between upward and downward bending and is convenient to use.

[0013] Furthermore, the bending action is directly driven by the rotary drive component to rotate the bending cutter, which increases the torque and completes the bending process of the sheet metal in one go. This replaces the existing X and Y axis interpolation to create an arc for bending, making the operation simple and convenient. It only requires calculating the bending angle, which reduces the control requirements for bending.

[0014] Preferably, each of the rotary drive components includes a motor, a reducer, an assembly block, and a tool holder, wherein the motor is connected and assembled with the reducer, the assembly block is disposed at the drive end of the reducer, and the bending cutter is assembled on the assembly block via the tool holder.

[0015] Preferably, the front end of the bending blade is provided with a flat portion, and in the bending state, the flat portion of the bending blade is in contact with the plate to form a surface contact.

[0016] By employing the aforementioned technical methods, the folding blade makes full contact when bending the sheet material, greatly increasing the contact area between the folding blade and the sheet material, improving the straightness and curvature of the bending process, and effectively preventing bulges from appearing on the product.

[0017] Preferably, the clamping mechanism includes an upper body control component, a lower template, and an upper template. The lower template is placed at the bottom of the feed inlet of the frame, the upper body control component is assembled at the front end of the frame, and the lower template is connected to the movable end of the upper body control component and located at the top of the feed inlet. The lower template and the upper template are corresponding vertically.

[0018] Preferably, the Y-axis control assembly includes a reducer, a bearing housing, a lead screw, a lead screw slider, a linear guide, a guide slider, and a support base.

[0019] Preferably, the lower bending unit and the upper bending unit are respectively assembled on the front end of the support base and are in an upper-lower corresponding relationship.

[0020] Preferably, the top surface of the feeding mechanism is provided with a brush.

[0021] A bending center includes a frame, a feeding mechanism, a clamping mechanism, a Y-axis control assembly, a bending control assembly, and a robotic arm truss. The robotic arm truss is disposed in the middle of the top surface of the feeding mechanism and is equipped with multiple suction cups for handling sheet metal.

[0022] Beneficial effects: The robotic arm gantry, in conjunction with the feeding mechanism and bending frame, can perform loading and unloading operations on the gripped sheet metal, thereby improving the automation level of sheet metal bending. Attached Figure Description

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0031] This utility model provides a bending machine.

[0032] Example 1, a bending machine, such as Figure 1-5 As shown, it includes a frame 1, a feeding mechanism 2, a clamping mechanism, a Y-axis control assembly 3, and a bending control assembly 4. The front end of the frame 1 is provided with a plate feed port, and the top surface of the feeding mechanism 2 is flush with the feed port.

[0033] The clamping mechanism is located at the feed inlet of the frame 1 to clamp and fix the feed plate, ensuring it is firmly fixed at the feed inlet position, and is used for subsequent bending processing. The Y-axis control assembly 3 is mounted on both sides of the frame 1 to drive the bending control assembly 4 to perform lifting and lowering movements.

[0034] The bending control component 4 is connected to the movable end of the Y-axis control component 3. The bending control component 4 includes a lower bending unit 41 and an upper bending unit 42. The lower bending unit 41 and the upper bending unit 42 are arranged vertically and vertically, and are set at the feed inlet position through the Y-axis control component 3 so that the material to be processed is located between the lower bending unit 41 and the upper bending unit 42.

[0035] When the sheet material needs to be bent upwards, the Y-axis control component 3 drives the bending control component 4 to move upwards until the bending unit 42 corresponds to the bending point of the sheet material and performs the upward bending process.

[0036] When the sheet material needs to be bent downwards, the Y-axis control component 3 drives the bending control component 4 to move downwards until the downward bending unit 41 corresponds to the bending point of the sheet material, and then performs the upward bending process.

[0037] The upward and downward bending of the sheet material is achieved by using the Y-axis control component 3 to drive a set of corresponding downward bending units 41 and upward bending units 42, which greatly improves the efficiency of switching between upward and downward bending and makes it convenient to use.

[0038] Both the lower bending unit 41 and the upper bending unit 42 include a rotary drive and a bending cutter 47. During bending, the rotary drive drives the bending cutter 47 to rotate along the central axis of the rotary drive, completing the bending process of the sheet metal in one go. This replaces the existing X and Y axis interpolation to create an arc for bending, making the operation simple and convenient. Only the bending angle needs to be calculated, which reduces the control requirements for bending.

[0039] The rotary drive components include a motor 43, a reducer 44, an assembly block 45, and a cutter holder 46. The motor 43 is connected and assembled with the reducer 44, the assembly block 45 is located at the drive end of the reducer 44, and the bending cutter 47 is assembled on the assembly block 45 through the cutter holder 46.

[0040] The front end of the bending blade 47 is provided with a flat part 471. In the bending state, the flat part 471 of the bending blade 47 is in contact with the plate to form a surface contact, so that the bending blade can make full contact when bending the plate, which greatly increases the contact area between the bending blade and the plate product, improves the straightness and bending arc of the bending, and effectively avoids the product from having bulges.

[0041] The Y-axis control assembly 3 includes a reducer 31, a bearing housing 32, a lead screw 33, a lead screw slider 34, a linear guide rail 35, a guide rail slider 36, and a support base 37.

[0042] Specifically, the output end of the reducer 31 is connected to the lead screw 33, and the other end of the lead screw 33 is connected to the bearing seat 32, so that the lead screw 33 can rotate. The lead screw slider 34 is threaded onto the lead screw 33. The linear guide rails 35 are arranged on both sides of the lead screw 33, and each linear guide rail 35 is slidably connected to the guide rail slider 36. The support seat 37 is installed on one side of the lead screw slider 34 and the guide rail slider 36. The lower bending unit 41 and the upper bending unit are respectively assembled on the front end of the support seat 37 and are in an upper and lower corresponding relationship.

[0043] The clamping mechanism includes an upper body control component 5, a lower template 6, and an upper template 7. The lower template 6 is placed at the bottom of the feed inlet of the frame 1. The upper body control component 5 is assembled at the front end of the frame 1. The lower template 6 is connected to the movable end of the upper body control component 5 and is located at the top of the feed inlet. The lower template 6 and the upper template 7 are corresponding vertically.

[0044] Before bending, the upper body control component 5 and the Y-axis control component 3 move in the same way. The upper body control component 5 drives the upper template 7 to move downward, and works with the lower template 6 to press and fix the sheet material, so that it is firmly fixed at the feed port position.

[0045] The top surface of the feeding mechanism 2 is equipped with a brush to automatically clean the conveyed board, reduce noise, and prevent scratches on the board.

[0046] Usage process: Two pairs of boards are conveyed to the feed port. Then, the upper control component 5 drives the upper template 7 to move downward, which works with the lower template 6 to press and fix the board product. When the board is bent, the Y-axis control component 3 drives the bending control component 4 to move upward until the upper bending unit 42 corresponds to the bending point of the board. At this time, the motor 43 and reducer 44 drive the assembly block 45 to rotate, so that the bending blade 47 on it rotates along the central axis of the motor 43 and reducer 44 to fold the board.

[0047] Example 2 differs from Example 1 in that the number of motors 43, reducers 44, and assembly blocks 45 in the rotary drive component is two. The two synchronously running motors 43 and reducers 44 drive the assembly blocks 45 to rotate the cutter holder 46, so that the bending cutter 47 segments are subjected to uniform force.

[0048] Example 3 differs from Example 1 in that the Y-axis control component 3 can use a synchronous belt module, which uses the meshing of the belt and the toothed pulley to achieve linear motion and drive the bending control component 4 to perform lifting and lowering motion. Alternatively, a gear and rack module can be used, which uses the meshing of the gear and rack to achieve linear motion and drive the bending control component 4 to perform lifting and lowering motion.

[0049] A bending center includes a frame 1, a feeding mechanism 2, a pressing mechanism, a Y-axis control component 3, a bending control component 4, and a robotic arm gantry 8, which is located in the middle of the top surface of the feeding mechanism 2. The robotic arm gantry 8 is equipped with multiple suction cups for handling sheet metal, and can grab sheet metal for loading and unloading operations, thereby improving the automation level of bending.

[0050] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.

[0051] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
