[0059] like Figure 1 , Figure 2 and Figure 3 , an embodiment of the present invention provides a support ring forming device for bending a flat bar 6 into a support ring, comprising: a frame 1, a feeding assembly 2, a transport mechanism 3 and a constant force bending assembly 4;

[0060] The feeding assembly 2 is mounted on the frame 1 and is used to drive the flat bar 6 to feed;

[0061] The transport mechanism 3 is installed on the frame 1 and is used to drive the feeding flat bar 6 to perform limited transport along a preset straight transport direction;

[0062] The constant force bending assembly 4 is mounted on the frame 1 and can constantly press the flat bar 6 in a direction perpendicular to the linear transport direction of the flat bar 6, so that the flat bar 6 is bent in a direction perpendicular to the linear transport direction;

[0063] The constant force bending assembly 4 can be moved and adjusted in a direction perpendicular to the linear transport direction to select a target diameter scale of the flat strip to be bent.

[0064] In this embodiment, the frame 1 is composed of a plurality of support plates, a plurality of support rods and other structures as a support carrier. The flat bar 6 is fed through the feed assembly 2, generally in the horizontal direction. The feed assembly 2 and the transport mechanism 3 can be arranged in the same horizontal direction. The feed assembly 2 drives the flat bar 6 to feed toward the transport mechanism 3, that is, the direction of the feed assembly 2 toward the transport mechanism 3 is the linear transport direction of the flat bar 6. After the flat bar 6 reaches the transport mechanism 3 from the feed assembly 2, the transport mechanism 3 continues to drive the flat bar 6 to move in the linear transport direction. The transport mechanism 3 has a directional limiting effect on the movement of the flat head, the purpose of which is to ensure that the flat head moves stably along the linear transport direction during the movement, and will not deviate or exceed the predetermined range. After the flat bar 6 is transported by the limited position of the transport mechanism 3, it reaches the constant force bending assembly 4, and then the constant force bending assembly 4 presses the flat bar 6 during the transportation process with a pressing head and a constant force, so that the flat bar 6 is continuously bent during the transportation process and formed into a support ring with equal diameter. The process of bending the flat bar 6 is automatically completed by the equipment and controlled by a key switch, thereby eliminating the defects of manual bending.

[0065] Specifically, the constant force bending component 4 applies pressure and constant force to the flat bar 6 during transportation, and the pressing direction is perpendicular to the linear transportation direction, so that the flat bar 6 is subjected to the bending force of the lateral pressure and bends. The constant force bending component 4 maintains a constant bending force, so that the flat bar 6 can be bent into a support ring of equal diameter during continuous transportation, and the forming is more beautiful, without straight segments and internal and external tilting.

[0066] Specifically, when support rings of different diameters need to be processed, the target bending diameter of the flat bar 6 can be controlled by adjusting the pressing position of the constant force bending assembly 4 in the vertical direction of the linear transport direction by pointing the pointer to the target diameter scale, thereby forming support rings of different diameters.

[0067] In a specific embodiment, the linear transport direction is the horizontal direction, and the direction perpendicular to the linear transport direction is the vertical direction, that is, the position adjustment of the constant force bending component 4 is also adjusted in the vertical direction. The constant force bending component 4 is set at the upper side of the transport mechanism 3. When the constant force bending component 4 is adjusted downward, the bending diameter of the flat bar 6 can be controlled to become smaller. When the constant force bending component 4 is adjusted upward, the bending diameter of the flat bar 6 can be controlled to become larger.

[0068] In this specific embodiment, the flat strip 6 faces downward when bent. To ensure that there is sufficient molding space below, the support plate at the bottom of the frame 1 can be extended horizontally outward, and a base assembly 5 is provided at the bottom of the extended portion. The entire frame 1 is lifted by the base assembly 5, and the space below the frame 1 corresponding to one side of the base assembly 5 serves as the molding space required when the flat strip 6 bends downward.

[0069] like Figure 4 As shown, the feed component 2 of the present application is described in detail below.

[0070] In one embodiment, the feed assembly 2 includes a support portion 21 , which is disposed on one side of the frame 1 . A feed trough 22 adapted to the width of the flat bar 6 is provided on the support portion 21 , and the guiding direction of the feed trough 22 is toward the transport mechanism 3 .

[0071] In this embodiment, one end of the support part 21 is fixed to one side of the frame 1 by screws, and the end of the support part 21 away from the frame 1 can be raised, and the raised height is adapted to the entrance height of the transport mechanism 3. Two convex edges are set on both sides of the raised position to form a feed trough 22. The flat bar 6 is placed on the feed trough 22 and can be kept facing the entrance of the transport mechanism 3, so that the flat bar 6 can accurately enter the transport mechanism 3 in the horizontal direction for transportation.

[0072] like Figure 3-7 , the transportation mechanism 3 of this application is introduced in detail below.

[0073] In one embodiment, the transport mechanism 3 includes a plurality of first guide components 31, a feeding component 32 and a pressing component 33;

[0074] A plurality of first guide assemblies 31 are disposed on the frame 1 and are used to guide the flat bar 6 toward a linear transport direction;

[0075] The feeding assembly 32 is disposed on the frame 1 and is used to drive the flat bar 6 to move in a linear transport direction;

[0076] The pressing assembly 33 is disposed on the frame 1 and above the feeding assembly 32 , and is used to press the limiting flat bar 6 to increase the conveying friction of the flat bar 6 , so as to limit the movement of the flat bar 6 in the straight conveying direction.

[0077] In this embodiment, Figure 8As shown, the first guide assembly 31 includes a guide block 311 and two guide rods 313; the guide block 311 is provided with a guide opening 312; the two guide rods 313 are inserted into the guide opening 312, and a guide gap is formed between the two guide rods 313. When the flat bar 6 reaches the transport mechanism 3 from the feed assembly 2, it first reaches the guide gap of at least one first guide assembly 31, and is guided by the guide gap of the first guide assembly 31 to move toward the feed assembly 32 and the clamping assembly 33. The feed assembly 32 is a driving component with a linear transport function, and the clamping assembly 33 presses the flat bar 6 down on the feed assembly 32, so that the feed assembly 32 drives the flat bar 6 to be transported in a limited position along the linear transport direction. During the transport process, the flat bar 6 continues to be limited by the guide gaps of other first guide assemblies 31, so as to ensure the accuracy of the transport direction of the flat bar 6.

[0078] In one embodiment, the feeding assembly 32 includes: a plurality of driving wheels 321 and a rotating driving member 322;

[0079] A plurality of driving wheels 321 are arranged side by side inside the frame 1 along the linear transport direction, and the plurality of driving wheels 321 are located at the rear end of the feed assembly 2 in the linear transport direction;

[0080] The rotating driving member 322 is disposed at the bottom of the frame 1 and is used to drive the multiple driving wheels 321 to rotate synchronously;

[0081] Among them, at least one first guide component 31 is located at the front end of the multiple driving wheels 321 in the linear transport direction, and at least one first guide component 31 is located between the multiple driving wheels 321 in the linear transport direction.

[0082] In this embodiment, the process of the flat bar 6 being transported by the feeding assembly 32 is as follows: after the flat bar 6 is fed from the feeding assembly 2, it first enters the guide slot of a first guide assembly 31 for a first limit, and then reaches the first driving wheel 321. The rotating driving member 322 drives the driving wheel 321 to rotate continuously, and the flat bar 6 can continuously move on the driving wheel 321. After the flat bar 6 passes through at least one driving wheel 321, it enters the guide slot of a first guide assembly 31 for a second limit. Preferably, in this embodiment, two driving wheels 321 are provided, and a first guide assembly 31 is provided between the driving wheels 321, so that the flat bar 6 can be driven to be transported stably along the linear transportation direction for a limited position.

[0083] In this embodiment, a knurling pattern may be provided on the surface of the driving wheel 321 , which can increase the friction coefficient between the driving wheel 321 and the flat bar 6 , thereby preventing the flat bar 6 from slipping, allowing the flat bar 6 to be transported at a constant speed, and ensuring smoothness when bending the flat bar 6 .

[0084] In this embodiment, the rotating drive member 322 adopts a motor, and the rotating shaft of the motor and the multiple driving wheels 321 are connected by a transmission belt, so as to realize the simultaneous rotation of the multiple driving wheels 321. Specifically, in order to ensure the rotation synchronization of the multiple driving wheels 321, a chain plate can be set at the end of the driving wheel 321, a gear can be set at the rotating shaft of the motor, and the transmission belt is a chain, and the synchronous rotation of the multiple driving wheels 321 is realized by chain transmission. Furthermore, in order to realize the tension adjustment of the chain, a movable tension wheel 323 is set on the frame, and the chain is sleeved on the tension wheel 323. The tightness of the chain can be adjusted by moving the tension wheel 323.

[0085] In one embodiment, the clamping assembly 33 includes: a plurality of clamping wheels 331 and a lifting drive member 332;

[0086] A plurality of clamping wheels 331 are arranged side by side inside the frame 1 along the linear transport direction, and the plurality of clamping wheels 331 are located above the plurality of driving wheels 321 and correspond one to one with the plurality of driving wheels 321;

[0087] The lifting drive member 332 is disposed on the top of the frame 1 and is used to drive the plurality of clamping wheels 331 to move in a direction vertical to the linear transport direction.

[0088] In this embodiment, the clamping assembly 33 is used to press the flat bar 6 downward so that the flat bar 6 is tightly attached to the driving wheel 321, thereby ensuring stable transportation of the flat bar 6. The number of clamping wheels 331 in the clamping assembly 33 can be the same as the number of driving wheels 321 and the positions can correspond one to one, that is, one clamping wheel 331 corresponds to one driving wheel 321 directly above the driving wheel 321, and the lifting drive 332 can simultaneously drive multiple clamping wheels 331 to move up and down synchronously, or multiple lifting drives 332 can be provided, and one lifting drive 332 drives one clamping wheel 331 to move up and down.

[0089] In this embodiment, the position of the pressing wheel 331 driven downward by the lifting drive member 332 needs to be adjusted according to the thickness of the flat bar 6, that is, the gap formed between the pressing wheel 331 and the corresponding driving wheel 321 after the pressing wheel 331 moves downward needs to ensure the stable passage of the flat bar 6, and play the role of fixing the flat bar 6 and continuously transporting the flat bar 6 during the bending process of the flat bar 6.

[0090] In this embodiment, the lifting drive member 332 can be a component with telescopic adjustment function such as a cylinder or an electric cylinder.

[0091] like Figure 7 As shown, the constant force bending component 4 of the present application is described in detail below.

[0092] In one embodiment, the constant force bending assembly 4 includes: a fixing frame 41, a sliding portion 42, a pressing roller 43, an adjusting member 44, a diameter scale plate 411 and a pointer 421;

[0093] The fixing frame 41 is fixed on the frame 1;

[0094] The sliding part 42 is slidably mounted on the fixing frame 41 in a direction perpendicular to the linear transport direction;

[0095] The pressing roller 43 is rotatably mounted on the sliding part 42. The pressing roller 43 corresponds to the driving wheel 321 located at the rear end of the plurality of driving wheels 321 in the linear transport direction, and is used to press the flat bar 6 with a pressing head and a constant force in a direction perpendicular to the linear transport direction. The pressing roller 43 is provided with roller teeth forming a pressing roller surface, and the roller teeth are used to press the flat bar head and make the flat bar 6 tangent to the roller tooth surface, so as to realize the bending and forming of the flat bar 6.

[0096] The adjusting member 44 is mounted on the fixing frame 41 and connected to the sliding portion 42, and is used to drive the sliding portion 42 to slide in a direction perpendicular to the linear transport direction;

[0097] A diameter scale nameplate 411 is mounted on the fixing frame 41;

[0098] The pointer 421 is installed on the sliding portion 42 .

[0099] In this embodiment, the fixing frame 41 serves as a carrier of the entire constant force bending assembly 4 . The fixing frame 41 may be a part of the frame 1 , or may be a component carrier separately installed on the frame 1 .

[0100] In this embodiment, the sliding part 42 is installed on the fixed frame 41 for sliding along the direction perpendicular to the linear transport direction, that is, it slides along the vertical direction. When the sliding part 42 slides along the vertical direction, it can drive the pressure roller 43 to move synchronously. When the pressure roller 43 moves up and down, it can change position with the rearmost driving wheel 321 among the multiple driving wheels 321, thereby realizing the adjustment of the bending diameter of the flat bar 6.

[0101] In this embodiment, the adjusting member 44 is used to drive the sliding part 42 to move and adjust on the fixing frame 41, so as to adjust the position of the pressing roller 43, that is, to adjust the bending diameter of the flat bar 6. In order to conveniently and accurately adjust the bending diameter of the flat bar 6, a scale method can be used for marking and identification, and the auxiliary adjusting member 44 can be adjusted accurately.

[0102] In this embodiment, two diameter scale nameplates 411 are provided and installed on both sides of the fixing frame 41. The two diameter scale nameplates 411 use a multi-zone scale method to mark multiple diameter ranges, and multiple pointers 421 are provided and correspond to multiple diameter ranges respectively. The sliding part 42 moves and drives the pointer 421 to move, select the diameter range to which the target bending diameter belongs, and use the position indicated by the pointer corresponding to the diameter range as the adjustment position, and locate the required target bending diameter within the diameter range, so that a support ring with equal diameter of the target bending diameter can be bent.

[0103] In this embodiment, the flat bar is bent by the cooperation between the pressure roller 43 and the corresponding driving wheel 321, and the pressure roller 43 also needs to rotate synchronously with the driving wheel 321. Therefore, when the rotating driving member 322 drives the driving wheel 321 to rotate, it also drives the pressure roller 43 to rotate. Specifically, taking the above-mentioned chain transmission as an example, the chain is also mounted on the gear set at the end of the pressure roller 43 for synchronous linkage.

[0104] Please continue reading Figure 7 In one embodiment, the adjusting member 44 includes a screw member 441 and a wheel member 442;

[0105] The screw rod 441 is installed on the fixing frame 41 and is arranged perpendicular to the linear transport direction, and the sliding part 42 is threadedly connected to the screw rod 441;

[0106] The wheel disc 442 is disposed on the fixing frame 41 and is meshed with one end of the screw rod 441 through a gear.

[0107] In this embodiment, the adjusting member 44 is adjusted by a screw rod, which has a high transmission efficiency and low friction loss in transmitting force, thereby ensuring the accuracy of adjustment; and the screw rod adjustment method is more stable.

[0108] In this embodiment, the roulette member 442 can be a manual roulette or an automatic roulette. The roulette member 442 and one end of the screw member 441 are meshed and connected via a bevel gear, thereby achieving the transmission of rotational force.

[0109] In one embodiment, the constant force bending assembly 4 also includes a second guide assembly 45; the second guide assembly 45 is arranged on the sliding portion 42 and is located at the bottom of the pressure roller 43; the second guide assembly 45 is provided with an arc-shaped guide groove, and the arc-shaped guide groove is used to form and limit the flat strip 6 after being pressed and bent by the pressure roller 43.

[0110] In this embodiment, the second guide assembly 45 is a block structure, and the arc-shaped guide groove in the second guide assembly 45 can prevent the flat strip 6 from swinging and twisting freely when being bent and discharged.

[0111] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
