[0081] like Figures 1 to 11 As shown, the automatic forming equipment for the C-type center support of this embodiment includes: a frame 1, a material unwinding rack 2, a main traction mechanism 3, a punching mechanism 4, a forming mechanism 5, a shearing mechanism 6, a measuring mechanism 7 and a controller.

[0082] The C-shaped center support 100 is in a rectangular frame shape, including: a bottom plate 110, a side plate 120 and a top plate 130. A notch (interval) is provided between the top plates 130 on both sides of the top, and a process hole 140 is provided on the bottom plate 110 and / or the side plate 120. The C-shaped center support 100 is generally formed by folding and bending a 1.5 mm thick galvanized steel plate.

[0083] The frame 1 is in the shape of a long rectangular parallelepiped, the unloading frame 2 is arranged outside the head end of the frame 1, the steel plate 21 is wound on the rotating shaft to form a steel plate material roll 22, and the rotating shaft of the steel plate material roll 22 is rotatably placed on the unloading frame 2. The width of the steel plate 21 corresponds to the sum of the widths of the bottom plate 110, the two side plates 120, and the two top plates 130 of the C-shaped center support 100.

[0084] The main traction mechanism 3 , the punching mechanism 4 , the forming mechanism 5 and the shearing mechanism 6 are sequentially arranged on the frame 1 from the head end of the frame 1 to the end end of the frame 1 .

[0085] The main traction mechanism 3 is arranged at the head end of the frame 1, and is used to pull the steel plate 21 of the steel plate coil 22, so that the steel plate is transmitted from the head end to the end (tail end) of the frame 1, and the main traction mechanism 3 rolls the transmitted steel plate flat.

[0086] The punching mechanism 4 is arranged at the rear end of the main traction mechanism 3. The steel plate conveyed by the main traction mechanism 3 passes through the punching mechanism 4. When the punching mechanism 4 is in action, it punches the preset position of the steel plate to form the process hole of the C-shaped center support.

[0087] The forming mechanism 5 is arranged at the rear end of the punching mechanism 4, and is used to clamp the steel plate and assist in transferring the steel plate to the rear end of the frame 1. The forming mechanism 5 includes: a top plate forming mechanism 51, a side plate preforming mechanism 52, and a side plate forming mechanism 53, and the top plate forming mechanism 51, the side plate preforming mechanism 52, and the side plate forming mechanism 53 are arranged in sequence from the head end to the tail end.

[0088] When the steel plate passes through the top plate forming mechanism 51, the top plate forming mechanism 51 folds the left and right sides of the steel plate upward 90° relative to the steel plate, that is, folds the top plate 130 of the C-shaped center support 100 90° relative to the side plates 120 to form the top plate of the C-shaped center support.

[0089] When the steel plate passes through the side plate preforming mechanism 52 , the side plate preforming mechanism 52 gradually folds the left and right sides of the steel plate relative to the steel plate, that is, the side plate 120 of the C-shaped center support 100 gradually folds relative to the bottom plate 110 .

[0090] When the steel plate passes through the side panel forming mechanism 53, the side panel forming mechanism 53 causes the steel plate folded by the side panel preforming mechanism 52 to continue to be folded until it is folded to 90°, that is, the side panel 120 of the C-shaped center support 100 continues to be folded relative to the bottom plate 110 until the side panel is folded to 90° relative to the bottom plate to form the side panel of the C-shaped center support, thereby folding the steel plate 21 into the C-shaped center support 100.

[0091] The shearing mechanism 6 is arranged at the end of the frame 1, and is used to shear the steel plate formed into the C-shaped center support according to a preset length, so as to obtain a C-shaped center support of a required length.

[0092] The main traction mechanism 3, the punching mechanism 4 and the shearing mechanism 6 are electrically connected to the controller respectively.

[0093] The measuring mechanism 7 includes a measuring roller 71 and an encoder.

[0094] The measuring roller 71 is rotatably arranged on the mounting bracket of the frame 1 through a fixed axis, and is located between the top plate forming mechanism 51 and the side plate preforming mechanism 52. The circumferential side surface of the measuring roller 71 is in contact with the top surface of the steel plate 21, and the steel plate drives the measuring roller 71 to rotate when it moves. The encoder (not shown in the figure) is arranged on the fixed axis and is electrically connected to the controller. The encoder detects the rotation angle of the measuring roller 71, thereby measuring the length of the steel plate 21 passing through. The encoder transmits the measured length of the steel plate to the controller, and the controller controls the stamping mechanism 4 to stamp the process hole 140 at the preset position of the steel plate according to the preset program, and controls the shearing mechanism 6 to shear the steel plate formed into the C-shaped middle support according to the preset length.

[0095] It is not difficult to find from the above content that the automatic forming equipment for the C-type center support of this embodiment is provided with a frame, a discharge rack, a main traction mechanism, a punching mechanism, a forming mechanism, a shearing mechanism, a measuring mechanism and a controller. The discharge rack is arranged on the outside of the head end of the frame, the main traction mechanism, the punching mechanism, the forming mechanism and the shearing mechanism are arranged on the frame in sequence, the forming mechanism is connected with the main traction mechanism by transmission, the forming mechanism includes a top plate forming mechanism, a side plate preforming mechanism and a side plate forming mechanism which are arranged in sequence, the measuring mechanism includes: a measuring roller and an encoder, the measuring roller is arranged on the frame through a fixed shaft, and is against the steel plate, and the encoder is arranged on the fixed shaft. The automatic forming equipment for the C-type center support of this embodiment is controlled by a PLC controller. The steel plate coil is placed on the unwinding rack. The main traction mechanism pulls the steel plate of the steel plate coil and transmits it to the rear end. The encoder measures the moving distance of the steel plate. The stamping mechanism stamps process holes at a preset position of the steel plate. The top plate forming mechanism folds both sides of the steel plate 90° to form the top plate of the C-type center support. The side plate preforming mechanism and the side plate forming mechanism fold both sides of the steel plate 90° to form the side plates of the C-type center support. The shearing mechanism cuts the steel plate formed into the C-type center support according to the preset length. The forming speed is fast and the efficiency is high, and the shape and quality of the formed C-type center support are basically consistent.

[0099] The rotating shaft of the main support roller 31 is connected to the servo motor through a transmission chain, and the main pressing roller 32 is connected to the rotating shaft of the main support roller 31. The servo motor drives the main support roller 31 to rotate, and the main support roller 31 drives the main pressing roller 32 to rotate when rotating, so that the clamped steel plate 21 is transmitted to the rear end of the frame 1. When the steel plate 21 is transmitted, the main support roller 31 and the main pressing roller 32 further flatten the steel plate 21.

[0100] Furthermore, in the automatic forming device for the C-shaped center support in this embodiment, the left and right ends of the main support roller 31 are provided with limit rings 311, and the distance between the limit rings 311 on both sides corresponds to the width of the steel plate. The steel plate is clamped between the limit rings 311 on both sides to prevent the steel plate from being deviated left and right during transmission.

[0101] Furthermore, the automatic forming equipment for the C-shaped center support in this embodiment also includes: a guide plate 8.

[0102] The guide plate 8 is fixed to the long hole of the frame 1 by fixing bolts, and the left and right sides of the guide plate 8 are set on the side walls of the frame 1 by adjusting bolts 81, so that the left and right position of the guide plate 8 on the frame 1 can be adjusted, and the guide plate 8 is located at the front end of the main traction mechanism 3.

The movable seat 43 is connected to the telescopic rod of the first oil cylinder 44, and the telescopic rod of the first oil cylinder 44 drives the movable seat 43 to rise and fall.

[0109] The movable seat 43 is provided with a guide sleeve 431, and the guide sleeve 431 of the movable seat 43 is slidably sleeved on the guide column 411 of the first bracket 41. The punch 45 is arranged on the movable seat 43, and the punch 45 is slidably penetrated in the punching hole 422 of the base 42, and is used to punch the steel plate 21 to form the process hole 140 of the C-shaped center support 100.

[0110] In this embodiment, the punching mechanism is arranged at the rear end of the main traction mechanism, and the steel plate transmitted by the main traction mechanism enters into the rectangular through hole of the base and passes through the rectangular through hole of the base. The encoder measures the moving distance (length) of the steel plate, and when the preset value is reached, the controller controls the steel plate to stop moving, and the first oil cylinder drives the punch to move downward to punch a process hole on the steel plate.

[0111] Of course, multiple stamping mechanisms can be set up, and multiple stamping mechanisms can be set up in front and behind.

[0115] The width of each group of first pressing rollers 512 is the same, and the width of the first pressing rollers 512 corresponds to the sum of the widths of the bottom plate 110 and the two side plates 120 of the C-shaped center support.

[0116] The first supporting roller 511 includes: a first light circular segment 5111 and a first tapered segment 5112 , and the first tapered segment 5112 is arranged on the left and right sides of the first light circular segment 5111 .

[0117] The width of the first light circular segment 5111 corresponds to the width of the first support roller 512, that is, the sum of the widths of the bottom plate of the C-shaped center support and the two side plates. From the head end to the tail end, the taper of the first conical segment 5112 of the multiple groups of first support rollers 511 gradually increases until it is 90°.

[0118] In this embodiment, the first round segment of the first supporting roller and the first pressing roller cooperate to clamp the steel plate and assist in transferring the steel plate to the rear end. When the steel plate moves to the rear end, the first conical segment of the first supporting roller gradually folds the left and right sides of the steel plate relative to the steel plate until the folding angle reaches 90°, forming the top plate 130 of the C-shaped center support 100.

[0119] Optional, such as Figure 3 , Figure 7 As shown, in the automatic forming equipment for the C-type center support in this embodiment, the side panel preforming mechanism 52 is arranged at the rear end of the top panel forming mechanism 51, including: multiple groups of second support rollers 521 and second pressure rollers 522.

The second support roller 521 and the second pressure roller 522 of each group are arranged up and down. Multiple groups of second support rollers 521 and second pressure rollers 522 are arranged in a front-to-back interval. The rotating shaft of the second support roller 521 is transmission connected to the rotating shaft of the first support roller 511.

[0123] From the head end to the tail end, the taper of the second conical section 5212 of the plurality of second support rollers 521 gradually increases. When the steel plate moves toward the rear end, the second conical section 5212 gradually folds the left and right sides of the steel plate upward relative to the steel plate, even if the side plates of the C-shaped middle support gradually fold upward relative to the bottom plate, so that the side plates are preformed until the top plate of the C-shaped middle support is adjacent to the end surface of the second pressing roller. At this time, the folding angle of the side plates relative to the bottom plate is less than 90°.

[0124] like Figure 8 and Fig. 9 As shown, the side panel forming mechanism 53 is arranged on the frame and is located at the rear end of the side panel preforming mechanism 52 , and includes: multiple groups of third support rollers 531 , third pressure rollers 532 and side rollers 533 .

[0125] The third support roller 531 , the third pressure roller 532 and the side roller 533 are respectively arranged on the frame 1 through rotating shafts, and the rotating shaft of the third support roller 531 is transmission-connected with the rotating shaft of the second support roller 521 .

The two side rollers 533 are rotatably arranged on the left and right sides of the third support roller 531 and the third pressure roller 532 through a bracket. From the head end to the tail end, the taper of the multiple groups of side rollers 533 gradually increases, and the side rollers 533 at the end of the side plate forming mechanism 53 are cylindrical. The side rollers 533 are against the steel plate part that has been folded by the side plate preforming mechanism 52, so that the two sides of the steel plate continue to be folded until they are folded to 90°, that is, the side plate of the C-shaped middle support is folded to 90° relative to the bottom plate, and the folding forming of the side plate is completed.

[0129] In this embodiment, the second conical section 5212 of the second supporting roller 521 gradually folds the two sides of the steel plate, so that the side panels of the C-shaped center support are gradually formed; the side rollers 533 of the side panel forming mechanism continue to fold the folded two sides until 90°, that is, the side panels of the C-shaped center support are folded 90° relative to the bottom plate.

[0130] Furthermore, in the automatic forming equipment for the C-shaped center support in this embodiment, both side end surfaces of the third pressing roller 532 are provided with protruding rings 5321.

[0132] In the top plate forming section, the top plate forming mechanism 51 makes the top plate folding angle less than 90°. In the side plate forming section, when the side plate of the C-shaped center support is folded and formed, the protruding ring 5321 of the third pressing roller 532 abuts against the top plate portion formed into the C-shaped center support, and continues to press down the top plate portion, so that the top plate folding angle is formed to 90°.

[0133] Optional, such as Figure 2 , Fig.10 As shown, in the automatic forming equipment for the C-shaped center support in this embodiment, the shearing mechanism 6 includes: a second bracket 61, a fixing seat 62, a second oil cylinder 63, a shearing die 64 and a sensor 65.

[0136] The profiled through hole 621 of the fixing seat 62 is adapted to the shape of the C-shaped center support 100, and the formed C-shaped center support passes through the profiled through hole 621 of the fixing seat 62. The cutting groove 622 of the fixing seat 62 is arranged perpendicular to the profiled through hole 621 and communicates with the profiled through hole 621.

[0137] The shearing die 64 is arranged on the movable rod of the second oil cylinder 63 through a connecting seat, the connecting seat is passed through the guide rod 611 of the second bracket 61, and the shearing die 64 can be slid up and down in the cutting groove 622 of the fixed seat 62, and is used to cut the steel plate formed into a C-shaped middle support.

[0138] The sensor 65 is disposed on the second bracket 61 and is electrically connected to the controller for sensing the position of the shearing die 64. When the shearing die 64 reaches the uppermost end and the lowermost end, the sensor 65 sends a position signal of the shearing die 64 to the controller, and the controller controls the shearing die 64 to stop lifting.

[0139] In this embodiment, the steel plate formed into a C-shaped center support passes through the contoured through hole of the fixed seat. When it reaches the preset length, the controller controls the main traction mechanism to stop, the steel plate stops moving, and the second oil cylinder drives the shearing die to move downward. The shearing die cuts the steel plate formed into the C-shaped center support according to the preset length.

[0140] Further, such as Fig.11 As shown, the automatic forming equipment for the C-type center support in this embodiment also includes: a straightening mechanism 9.

[0141] The straightening mechanism 9 is arranged on the frame 1 , and is located at the front end of the shearing mechanism 6 , and between the side plate forming mechanism 53 and the shearing mechanism 6 .

[0142] The alignment mechanism 9 includes: a plurality of alignment support rollers 91 (three) and alignment pressure rollers 92 (two), and the number of the alignment support rollers 91 is one more than the number of the alignment pressure rollers 92.

[0144] The straightening pressing roller 92 is provided with a first disc 921 and a second disc 922 .

[0145] The second disc 922 is disposed on the left and right sides of the first disc 921, and the first disc 921 and the second disc 922 are spaced apart, and a second chute is formed between the first disc 921 and the second disc 922. The width of the first disc 921 corresponds to the gap distance between the top plate 130 of the C-shaped center support, and the width of the second chute corresponds to the width of the top plate 130 of the C-shaped center support.

[0146] The straightening support roller 91 and the straightening pressure roller 92 are rotatably arranged on the frame 1 , respectively, and a plurality of straightening support rollers 91 and straightening pressure rollers 92 are staggered up and down, and the straightening pressure roller 92 is located between two adjacent straightening support rollers 91 .

[0147] The steel plate formed into the C-shaped center support passes through the first chute of the straightening support roller, and the bottom is against the straightening support roller, and the straightening support roller 91 supports the bottom plate of the C-shaped center support. Then, the top plate and side plates of the steel plate (C-shaped center support) pass through the second chute of the straightening pressure roller 92, and the first disc 921 of the straightening pressure roller 92 extends into the C-shaped center support and is against the top surface of the bottom plate of the C-shaped center support, and the second disc 922 is against the side wall of the side plate, and the straightening pressure roller 92 presses down on the bottom plate of the C-shaped center support. During the movement of the steel plate (C-shaped center support) to the rear end, the first disc 921 of the straightening pressure roller 92 presses down on the bottom plate of the C-shaped center support, so that the steel plate (C-shaped center support) is stretched, thereby making the bottom plate (C-shaped center support) more flat and straight.

[0148] The automatic forming equipment for C-type center support of the utility model has the following working process:

[0149] The steel plate coil is placed on the unwinding rack and manually controlled first. The steel plate is guided by the guide plate and then fed into the main traction mechanism. When the head end of the steel plate moves to the measuring roller of the measuring mechanism, the measuring roller is driven to rotate. The encoder measures the length of the steel plate through the rotation angle of the measuring roller. The controller is started and the equipment enters the automatic working state.

[0150] The main support roller and main pressure roller of the main traction mechanism clamp the steel plate and transmit the steel plate to the rear end. The steel plate passes through the stamping mechanism. After the steel plate moves a preset length, the controller controls the steel plate to stop moving through the main traction mechanism, and the stamping mechanism punches process holes on the steel plate.

[0151] When the steel plate passes through the top plate forming mechanism, the first conical section of the first supporting roller gradually folds the two sides of the steel plate relative to the steel plate until they are folded into 90 degrees.

[0152] When the steel plate passes through the side plate preforming mechanism, the second conical section of the second supporting roller of the side plate preforming mechanism causes the two sides of the steel plate to be gradually folded relative to the steel plate.

[0153] When the steel plate passes through the side plate forming mechanism, the side rollers of the side plate forming mechanism cause the two sides of the steel plate to continue to be folded relative to the steel plate until they are folded to 90 degrees, so that the steel plate is formed into a C-shaped center support.

[0154] When the steel plate passes through the straightening mechanism, the straightening support roller and the straightening pressure roller of the straightening mechanism stretch the C-shaped center support to make the C-shaped center support more flat and straight.

[0155] Finally, the steel plate (C-shaped middle support) passes through the contoured through hole of the fixing seat. After moving a preset length, the controller controls the steel plate (C-shaped middle support) to stop moving, and the shearing die cuts off the C-shaped middle support.
