Description

Technical Field

[0001] The utility model relates to the field of building supplies processing equipment, and more specifically, to a back rib flanging stamping machine. Background Art

[0002] For the back ribs used in existing building templates, in order to prevent the problem of jamming at the edge of the strip hole when the bolt is inserted into or withdrawn from the strip hole during the installation of the back rib. For example, the published patent No. CN115045501A discloses a back rib, and the strip hole on the back rib has an inner flanging, which avoids the problem of jamming when the bolt is inserted or withdrawn through the inner flanging.

[0003] The flanging on the back rib is often processed by stamping technology. The back rib with the cut size is placed into the stamping die, and stamping is carried out at the strip hole to generate the flanging. However, each stamping can only complete the processing of a single back rib, and the frequent loading and unloading seriously affects the production efficiency. Summary of the Utility Model

[0004] The utility model aims to overcome the problem of low flanging processing efficiency of the back rib in the above-mentioned prior art, and provides a back rib flanging stamping machine, which can continuously stamp multiple flangings on the back rib and improve the production efficiency of the back rib.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a back rib flanging stamping machine, comprising a frame, a stamping die both installed on the frame, a stamping mechanism located on one side or opposite sides of the stamping die, and a traction device located at the discharging end of the stamping die; the traction device includes a clamping assembly for clamping the back rib and a driving assembly for driving the clamping assembly to move away from the stamping die.

[0006] In the above technical solution, the whole back rib is loaded into the stamping die, one end of the back rib passing through the die core of the stamping die is clamped by the clamping assembly. After the stamping mechanism completes the flanging stamping of the back rib in the stamping die, the stamping mechanism resets, and the driving assembly drives the clamping assembly to move away from the stamping die, so that the back rib continues to enter the die core of the stamping die. After the driving assembly moves a certain distance, it stops, and the stamping mechanism punches another position of the back rib to form a flanging, and then the stamping mechanism resets. The back rib flanging stamping machine automatically repeats the above process to complete the punching and flanging processing of the whole section of the back rib at one time, and then cuts the back rib into different sizes during subsequent use, thereby reducing the number of loading and unloading times during the back rib flanging processing.

[0007] Preferably, strip holes are provided on both sides of the stamping die; two stamping mechanisms are provided, respectively located on both sides of the stamping die. The stamping mechanism includes a punch and a first driving member for driving the punch to extend into the die core. The two stamping mechanisms can simultaneously complete the flanging process on both sides of the back rib, with higher processing efficiency. The first driving member can be a component such as a cylinder or a hydraulic cylinder.

[0008] Preferably, a pressing device is further installed on the frame. The stamping die is provided with a hollowed-out portion, and the pressing device is used to pass through the hollowed-out portion and press the back rib located within the stamping die. Before the stamping mechanism performs stamping, the pressing device first presses the back rib to prevent the back rib from moving during the stamping and flanging process, which may affect the forming effect of the flanging.

[0009] Preferably, the pressing device includes a pressing head for extending into the hollowed-out portion and a second driving member for driving the pressing head to move; the pressing device is located at the top of the stamping die. The second driving member drives the pressing head to pass through the hollowed-out portion and press the top surface of the back rib located within the stamping die. The second driving member can be a component such as a cylinder or a hydraulic cylinder. Considering avoiding deformation of the back rib caused by excessive pressure, using a cylinder is a better solution.

[0010] Preferably, the clamping assembly includes a mounting seat connected to the driving assembly, a clamping mechanism mounted on the mounting seat, and a third driving member for driving the clamping mechanism to clamp the back rib. The clamping mechanism can be a pneumatic gripper or a mechanical gripper, etc. After the back rib passes through the stamping die, the third driving member drives the clamping mechanism to clamp the back rib, enabling the clamping assembly to drive the back rib to move. The third driving member can be a cylinder or a hydraulic cylinder, etc.

[0011] Preferably, the third driving member is connected to the mounting seat; the clamping mechanism includes a positioning member connected to the mounting seat and a clamping member rotatably connected to the positioning member. One end of the clamping member is slidably connected to the output end of the third driving member. The positioning member is provided with an inner support plate for extending into the back rib, and the end of the clamping member abuts against the top surface of the inner support plate under the action of the third driving member. After the back rib passes through the stamping die, its end abuts against the positioning member, and the inner support plate of the positioning member extends into the back rib and fits against the inner top surface of the back rib. At this time, the third driving member drives the clamping member to rotate around the positioning member, causing the end of the clamping member to rotate towards the inner support plate. If there is no back rib, the end of the clamping member will abut against the top surface of the inner support plate. However, since the inner support plate is located within the back rib, it becomes the clamping member pressing against the top surface of the back rib, thereby clamping the back rib together with the inner support plate.

[0012] Preferably, the driving assembly includes a sliding plate slidably connected to the frame, a motor mounted on the sliding plate, and a gear mounted on the output shaft of the motor; a rack meshing with the gear is mounted on the frame; the mounting seat is connected to the sliding plate. The gear rotates and moves along the rack under the drive of the motor, so that the sliding plate slides on the frame, and the mounting seat connected to the sliding plate can also move along with the sliding plate.

[0013] Preferably, a sliding rod is mounted on the frame, and the sliding plate is slidably connected to the frame through the sliding rod. The sliding rod can increase the sliding stability between the sliding plate and the frame.

[0014] Preferably, it includes a supporting table, and the supporting table is located on the side of the stamping die away from the traction device. Since the length of the back rib processed at one time is relatively long, the supporting table can support the back rib to prevent the part of the back rib outside the stamping die from being bent.

[0015] Preferably, conveying rollers are mounted on the supporting table, and the rotation axes of the conveying rollers are perpendicular to the moving direction of the clamping assembly. The conveying rollers can reduce the movement resistance of the back rib on the supporting table, reduce the load burden of the clamping assembly, and make the movement of pulling the back rib smoother.

[0016] Compared with the prior art, the beneficial effects are as follows: Through the linkage of the traction device and the stamping mechanism, after the back rib is pulled forward by a specified distance by the traction device, the stamping mechanism performs flanging stamping processing until the processing of the entire back rib is completed, realizing that the flanging of an entire back rib can be completed with one loading without manual intervention during the process, and improving the processing efficiency of flanging.

[0026] The technical solution of the present utility model will be further specifically described below through specific embodiments in conjunction with the accompanying drawings:

[0027] Embodiment 1

[0028] As Figure 1-2Shown is Embodiment 1 of a back rib flanging stamping machine, including a frame 1, a stamping die 2 both installed on the frame 1, stamping mechanisms 3 located on opposite sides of the stamping die 2, and a traction device located at the discharge end of the stamping die 2; the traction device includes a clamping assembly 4 for clamping the back rib and a driving assembly 5 for driving the clamping assembly 4 to move away from the stamping die 2.

[0029] In this embodiment, strip-shaped holes 201 are provided on both sides of the stamping die 2; there are two stamping mechanisms 3, respectively located on both sides of the stamping die 2. The stamping mechanism 3 includes a punch 301 and a first driving member 302 for driving the punch 301 to extend into the die core 202 of the stamping die 2. The two stamping mechanisms 3 can simultaneously complete the flanging processing on both sides of the back rib, with higher processing efficiency. The first driving member is a cylinder in this embodiment.

[0030] Furthermore, a pressing device 6 is also installed on the frame 1. The stamping die 2 is provided with a hollowed-out portion 203. The pressing device 6 is used to pass through the hollowed-out portion 203 and press the back rib located inside the stamping die 2. Before the stamping mechanism 3 performs stamping, the pressing device 6 first presses the back rib to prevent the back rib from moving during the stamping and flanging process, which may affect the forming effect of the flanging. The pressing device 6 includes a pressing head 601 for extending into the hollowed-out portion 203 and a second driving member 602 for driving the pressing head 601 to move; the pressing device 6 is located at the top of the stamping die 2. The second driving member 602 drives the pressing head 601 to pass through the hollowed-out portion 203 and press the top surface of the back rib located inside the stamping die 2. The second driving member 602 is a cylinder in this embodiment.

[0031] The working principle or working process of this embodiment: The entire back rib is loaded into the stamping die 2. One end of the back rib passing through the die core 202 of the stamping die 2 is clamped by the clamping assembly 4. The second driving member 602 drives the pressing head 601 to press the back rib inside the stamping die 2. The first driving member 302 drives the punch 301 to stamp the back rib to form a flanging. When the stamping mechanism 3 completes the stamping of the flanging of the back rib inside the stamping die 2, the stamping mechanism 3 and the pressing device 6 return to their original positions. The driving assembly 5 drives the clamping assembly 4 to move away from the stamping die 2, causing the back rib to continue to enter the die core 202 of the stamping die 2. After the driving assembly 5 moves a certain distance, it stops. The pressing device 6 presses the back rib again, and the stamping mechanism 3 punches another position of the back rib and forms a flanging, and then the stamping mechanism 3 and the pressing device 6 return to their original positions. The back rib flanging stamping machine automatically repeats the above process to complete the punching and flanging processing of the entire section of the back rib at one time, and then performs slitting of different sizes on the back rib during subsequent use, thereby reducing the number of times of loading and unloading during the back rib flanging processing.

[0032] The beneficial effects of this embodiment are as follows: through the linkage effect of the traction device and the stamping mechanism 3, after the back rib is pulled forward a specified distance by the traction device, the stamping mechanism 3 performs the stamping process of the flanging until the processing of the entire section of the back rib is completed, so that the flanging of a whole section of the back rib can be completed in one loading and the process does not require manual intervention, thereby improving the processing efficiency of the flanging.

[0033] Example 2

[0034] Embodiment 2 of a back flanging punching machine further defines the traction device based on embodiment 1.

[0035] like Figure 3 As shown, the clamping assembly 4 includes a mounting seat 401 connected to the driving assembly 5, a snap mechanism installed on the mounting seat 401, and a third driving member 402 that drives the snap mechanism to clamp the back rib. Specifically, the third driving member 402 is connected to the mounting seat 401; the snap mechanism includes a clamping member 403 connected to the mounting seat 401 and a clamping member 404 rotatably connected to the clamping member 403, one end of the clamping member 404 is slidably connected to the output end of the third driving member 402, the clamping member 403 is provided with an inner support plate 4031 for extending into the back rib, and the end of the clamping member 404 abuts against the top surface of the inner support plate 4031 under the action of the third driving member 402. After the back rib passes through the stamping die 2, its end contacts the clamping piece 403 and the inner support plate 4031 of the clamping piece 403 extends into the back rib and fits with the inner top surface of the back rib. At this time, the third driving member 402 drives the clamping member 404 to rotate around the clamping member 403, so that the end of the clamping member 404 rotates toward the inner support plate 4031. If there is no back rib, the end of the clamping member 404 will contact the top surface of the inner support plate 4031. Since the inner support plate 4031 is located in the back rib, the clamping member 404 is pressed against the top surface of the back rib, thereby clamping the back rib together with the inner support plate 4031. Figure 4 As shown, the positioning member 403 can position the back rib 8 so that the back rib 8 is accurately positioned, and the bite action of the inner support plate 4031 and the clamping member 403 causes stress to be applied to both the inner and outer surfaces of the back rib 8, thereby better clamping the back rib 8.

[0036] Furthermore, the driving assembly 5 includes a slide plate 501 slidably connected to the frame 1, a motor 502 mounted on the slide plate 501, and a gear 503 mounted on the output shaft of the motor 502; Figure 4As shown in the figure, a rack 101 meshing with a gear 503 is installed on a frame 1; a mounting base 401 is connected to a sliding plate 501. The gear 503 rotates and moves along the rack 101 under the drive of a motor 502, so that the sliding plate 501 slides on the frame 1, and the mounting base 401 connected to the sliding plate 501 can also move together with the sliding plate 501. In this embodiment, a slide bar 102 is installed on the frame 1, and the sliding plate 501 is slidably connected to the frame 1 through the slide bar 102. The slide bar 102 can increase the sliding stability between the sliding plate 501 and the frame 1.

[0037] In this embodiment, the motor 502 is a servo motor 502, and the distance of each movement of the clamping assembly 4 can be controlled by controlling the rotation angle, so as to control the distance between two adjacent flanges of the back rib.

[0038] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0039] Embodiment 3

[0040] An Embodiment 3 of a back rib flanging stamping machine, based on Embodiment 1 or Embodiment 2, is different from Embodiment 1 and Embodiment 2 in that, as Figure 5 shown, it includes a supporting table 7, and the supporting table 7 is located on the side of the stamping die 2 away from the traction device. Since the back rib processed at one time is relatively long, the supporting table 7 can support the back rib to prevent the part of the back rib outside the stamping die 2 from being bent.

[0041] In this embodiment, conveying rollers 701 are installed on the supporting table 7, and the rotation axes of the conveying rollers 701 are perpendicular to the movement direction of the clamping assembly 4. The conveying rollers 701 can reduce the movement resistance of the back rib on the supporting table 7, reduce the load burden of the clamping assembly 4, and make the movement of pulling the back rib smoother.

[0042] The remaining features and working principles of this embodiment are the same as those of Embodiment 1 or 2.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
