Description

Technical Field

[0001] This application relates to the field of metal processing technology, and in particular to a stainless steel fastener processing device. Background Technology

[0002] During the production of box-type floating roofs, stainless steel fasteners are placed at the joints, serving a dual crucial function of structural connection and sealing. As a structural connector, they tightly link adjacent floating roof panels, effectively enhancing the overall rigidity and structural integrity of the floating roof. As a sealing component, they apply high-intensity mechanical pressure to uniformly press special sealing materials such as fluororubber membranes or elastic sealing strips onto the joint surface, forming a continuous, leak-free sealing strip that ensures long-term reliable sealing of the system.

[0003] Stainless steel fasteners typically feature a U-shaped cross-section design with multiple through holes on both sides for connectors to pass through. Currently, the processing of these stainless steel fasteners generally requires first cutting the stainless steel substrate to a predetermined size, followed by punching and bending operations using CNC punching and bending equipment respectively. However, these processes are mostly performed independently, limiting the improvement of overall processing efficiency. Furthermore, thin sheet materials (stainless steel) with good ductility are prone to plastic deformation rather than brittle fracture during stamping, thus easily leading to edge stretching and curling. Summary of the Invention

[0004] This application aims to at least partially solve one of the technical problems in the aforementioned technologies.

[0005] Therefore, one objective of this application is to provide a stainless steel buckle processing device that effectively integrates bending and punching processes to improve processing efficiency. Furthermore, during punching, the bending die presses the substrate from all directions, thereby reducing the occurrence of deformation of the connecting holes.

[0006] To achieve the above objectives, a first aspect of this application provides a stainless steel fastener processing device, comprising: a frame, a shaping mechanism, a stamping mechanism, and a punching mechanism. The shaping mechanism includes a punch and two positioning components, wherein the punch and the two positioning components are respectively mounted on the frame, and the two positioning components are symmetrically arranged at both ends of the punch. A stainless steel substrate to be processed is placed on the punch and located between the two positioning components. The punch has a plurality of equidistantly arranged first through holes. The stamping mechanism and the punching mechanism are respectively mounted on the frame. The stamping mechanism includes two recesses... The template includes two concave templates symmetrically arranged above the punch. Each concave template has multiple second through holes arranged at equal intervals. A top surface is provided above the concave template. The minimum distance between the second through holes and the top surface is equal to the minimum distance between the first through hole and the upper surface of the stainless steel substrate to be processed. The diameter of the first through hole is equal to the diameter of the second through hole. A punching mechanism is arranged on one side of the punch. The punching mechanism includes multiple cutting tools, which are arranged directly opposite the first through holes. An ejector mechanism is provided on the frame, with one end of the ejector mechanism extending into the interior of the punch.

[0007] In addition, the stainless steel buckle processing device proposed in the above embodiments of this application may also have the following additional technical features: Furthermore, the stamping mechanism also includes a bracket, a hydraulic telescopic rod, a plate, two connecting plates, and multiple reset components. The bracket is connected to the platform, and the hydraulic telescopic rod is mounted on the bracket. The plate is connected to the output end of the hydraulic telescopic rod. The two connecting plates are symmetrically arranged on the plate and are pivotally connected to the two concave templates via shafts. The two concave templates are arranged in an equilateral triangle structure, and the multiple reset components are respectively disposed between the two concave templates and the plate.

[0008] Furthermore, the distance between the shaft and the upper surface of the concave template is greater than the distance between the shaft and the lower surface of the concave template.

[0009] Furthermore, the punching mechanism also includes a fixed frame, a first cylinder, and a guide rail, wherein a plurality of the cutting tools are equidistantly mounted on the fixed frame; the first cylinder and the guide rail are respectively disposed on the frame, wherein the output end of the first cylinder is connected to the fixed frame, and the fixed frame is slidably connected to the guide rail.

[0010] Furthermore, the positioning assembly includes a base, an electric telescopic rod, and a self-extending component, wherein the base is disposed on the platform; the electric telescopic rod is mounted on the base; a guide groove is provided on the punch, the self-extending component is slidably disposed inside the guide groove, the output end of the electric telescopic rod is connected to the self-extending component; and the stainless steel substrate to be processed abuts against the self-extending component.

[0011] Furthermore, an infrared alignment device is provided on one of the bases.

[0012] Furthermore, the ejector mechanism is located below the shaping mechanism. The ejector mechanism includes a second cylinder, a carrier plate, and two ejector rods. The second cylinder is mounted on the frame, the carrier plate is connected to the output end of the second cylinder, and the two ejector rods are symmetrically arranged on the carrier plate. One end of each ejector rod passes through the upper surface of the frame and the punch in sequence, and is slidably connected to the frame and the punch.

[0013] Furthermore, the plurality of the cutting tools are arranged in a stepped structure, and the cutting edges of the cutting tools are provided with bevels.

[0014] The stainless steel buckle processing device of this application embodiment first precisely bends the base material through the stamping mechanism, and then completes the punching operation at the same station, improving the overall processing efficiency. During the punching process, the stamping mechanism and the punch cooperate to play a clamping and positioning role, effectively fixing the base material, and providing sufficient support to the area around the hole during punching, thereby preventing the connecting hole from deforming and ensuring stable forming quality.

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] The stainless steel buckle processing apparatus of this application embodiment is described below with reference to the accompanying drawings.

[0020] like Figures 1-5 As shown, the stainless steel buckle processing device of this application embodiment may include: a frame 1, a shaping mechanism 2, a stamping mechanism 3, and a punching mechanism 4.

[0021] The shaping mechanism 2 includes a punch 21 and two positioning components 22.

[0022] The punch 21 and two positioning components 22 are respectively set on the frame 1. The two positioning components 22 are symmetrically arranged at both ends of the punch 21. The stainless steel substrate to be processed is placed on the punch 21 and is located between the two positioning components 22. The punch 21 is used to support the stainless steel substrate during processing, and the positioning components 22 are used to fix the stainless steel substrate.

[0023] It should be noted that the stainless steel substrate described in this embodiment is used for the processing of the fastener strip. During the installation process, it is required to have a certain deformation capacity as a sealing element. Therefore, thin stainless steel sheet is selected, which has a better shaping effect after bending.

[0024] The punch 21 has multiple first through holes 23 arranged at equal intervals.

[0025] The stamping mechanism 3 and the punching mechanism 4 are respectively installed on the frame 1. The stamping mechanism 3 includes two concave templates 31.

[0026] Two concave templates 31 are symmetrically arranged above the punch 21. Multiple second through holes 32 are equidistantly arranged on the concave templates 31. A top surface 30 is provided above the concave templates 31. The minimum distance between the second through holes 32 and the top surface 30 is equal to the minimum distance between the first through hole 23 and the upper surface of the stainless steel substrate to be processed.

[0027] The diameter of the first through hole 23 is equal to the diameter of the second through hole 32.

[0028] It is understandable that the minimum distance between the second through hole 32 and the top surface 30 is equal to the minimum distance between the first through hole 23 and the upper surface of the stainless steel substrate to be processed, which indicates that when the concave template 31 moves to the lowest point, the first through hole 23 and the second through hole 32 are directly opposite each other.

[0029] It should be noted that when the two concave templates 31 described in this embodiment are vertical, the distance between them is approximately (within a reasonable range of processing error according to product technical requirements) equal to the sum of the width of the punch 21 and the thickness of the two layers of stainless steel substrate, so as to ensure that the stainless steel substrate can be bent into a U-shaped structure when the two concave templates 31 and the punch 21 are closed.

[0030] The punching mechanism 4 is arranged on one side of the punch 21. The punching mechanism 4 includes a plurality of cutting tools 41, wherein the plurality of cutting tools 41 are arranged opposite to the first through hole 23.

[0031] It should be noted that the diameter of the cutting tool 41 described in this embodiment is approximately equal to the diameter of the first through hole 23 and the second through hole 32, and the diameter difference is less than the maximum allowable error in machining the connecting hole of the stainless steel substrate.

[0032] In addition, the length of the cutting tool 41 is greater than the thickness of the two concave templates 31 and the punch 21 after they are closed. That is, after punching, the cutting tool 41 can penetrate the two concave templates 31 and the punch 21, thereby pushing out the waste material, which is convenient for subsequent collection operations.

[0033] It should be noted that when the cutting tool 41 interacts with the stainless steel substrate to be processed, the first through hole 23 and the second through hole 32 can also play a guiding role, reducing the probability of the cutting tool 41 being damaged during processing, thereby extending the service life of the cutting tool 41.

[0034] The stand 1 is equipped with an ejector mechanism 5, one end of which extends into the interior of the punch 21.

[0035] In the embodiments of this application, the number of multiple first through holes 23, multiple second through holes 32 and multiple cutting tools 41 are equal. The specific number can be determined according to the length requirements of the stainless steel buckle, for example: 3, 4, 5, etc., and is not specifically limited here.

[0036] Furthermore, this stainless steel buckle processing device can be based on the control principle of CNC machine tools. A control device is set on the frame 1. The positioning component 22, the stamping mechanism 3, the punching mechanism 4 and the ejection mechanism 5 are respectively connected to the control device. The control device may include a control panel, which is equipped with a display screen and function buttons, so that relevant personnel can conveniently view the data of the stainless steel buckle processing device during operation through the display screen, and conveniently adjust and modify the data by inputting the buttons.

[0037] Specifically, relevant technicians use external machining equipment (e.g., mechanical shearing equipment) to obtain a certain length of stainless steel substrate to be processed (the top can be removed according to the actual situation).

[0038] The stainless steel substrate to be processed is placed on the punch 21. When the device is run, the two positioning components 22 fix the stainless steel substrate to be processed. Then the stamping mechanism 3 runs and the two concave templates 31 move toward the stainless steel substrate to be processed until the top surface 30 is in contact with the upper surface of the stainless steel substrate (this condition can be obtained by a position sensor or a pressure sensor). At this time, the two concave templates 31 are in a vertical state, and the stainless steel substrate is in a U-shaped structure and is stuck on the punch 21. The first through hole 23 and the second through hole 32 are facing each other.

[0039] Afterwards, the punching mechanism 4 operates, and multiple cutters 41 enter the second through hole 32 on a corresponding concave template 31 and interact with the stainless steel substrate. After the cutter 41 penetrates the stainless steel substrate, the waste material is pushed out from the second through hole 32 on another concave template 31.

[0040] The stamping mechanism 3 and the punch 21 work together to clamp and position the substrate, effectively fixing it and providing sufficient support to the area around the hole during punching, thereby preventing deformation of the connecting hole and ensuring stable forming quality.

[0041] The punching mechanism 4, the stamping mechanism 3, and the positioning component 22 are reset in sequence. The processed stainless steel buckle is snapped onto the punch 21. The ejector mechanism 5 applies force to the stainless steel buckle, thereby separating the stainless steel buckle from the punch 21. Then, relevant technicians can remove the stainless steel buckle and place it in the target position. Repeating the above steps can complete the processing of a batch of stainless steel buckles.

[0042] This device improves workpiece processing efficiency and overall process reliability by efficiently integrating bending and punching processes.

[0043] In another embodiment of this application, the device can be used to perform a single bending process on a stainless steel substrate or other thin plate to produce a metal part with a U-shaped cross-section. The specific working principle has been disclosed in the above embodiments, so it will not be described in detail here. This ultimately improves the applicability of the device.

[0044] In one embodiment of this application, such as Figure 2 As shown, the stamping mechanism 3 also includes a bracket 33, a hydraulic telescopic rod 34, a plate 35, two connecting plates 36, and multiple reset components 37.

[0045] Among them, the bracket 33 is connected to the platform 1, the hydraulic telescopic rod 34 is installed on the bracket 33, the plate 35 is connected to the output end of the hydraulic telescopic rod 34, and two connecting plates 36 are symmetrically arranged on the plate 35. The two connecting plates 36 are respectively pivotally connected to the two concave templates 31 through the shaft.

[0046] The two concave templates 31 are arranged in an equilateral triangle structure, and multiple reset pieces 37 are respectively set between the two concave templates 31 and the plate 35.

[0047] It should be noted that the reset component 37 described in this embodiment may include an arc-shaped rod, a spring, and a fixing component. One end of the arc-shaped rod is connected to the concave template 31, the spring is sleeved on the arc-shaped rod, the arc-shaped rod is slidably connected to the fixing component, and the fixing component is connected to the plate 35. Its specific working principle has been disclosed in the prior art, so it will not be described in detail here.

[0048] Specifically, during the operation of the stamping mechanism 3, the hydraulic telescopic rod 34 pushes the plate 35 downward. Under the action of the connecting plate 36, the two concave templates 31, which are in the shape of an equilateral triangle, apply force to the edge near the stainless steel substrate. The two sides of the stainless steel substrate bend towards the punch 21. When the bent part of the stainless steel substrate comes into contact with the two concave templates 31, the two concave templates 31 rotate around the axis. The two concave templates 31 tend to rotate in the vertical direction until the top surface 30 is in contact with the upper surface of the stainless steel substrate. The cross section of the stainless steel substrate presents a U-shaped structure.

[0049] When the stamping mechanism 3 is reset, due to the fixing of the stainless steel buckle by the positioning component 22 and the friction between the stainless steel buckle and the punch 21, the stainless steel buckle will not move with the stamping mechanism 3. Under the action of the reset component 37, the two concave templates 31 are reset.

[0050] In the embodiments of this application, the concave template 31 first applies a force to the edge of the stainless steel substrate, and then the relative movement between the concave template 31 and the punch 21 pushes the concave template 31 to rotate around the axis, and the concave template 31 pushes the stainless steel substrate in the direction of the punch 21, thereby completing the bending of the stainless steel substrate.

[0051] Compared to rapid vertical stamping, this progressive bending method requires less ductility from the material due to its gradual deformation, thus reducing the risk of cracking caused by sudden and drastic deformation.

[0052] As a possible scenario, to prevent the concave template 31 from scratching the surface of the stainless steel substrate when it comes into contact with it, an arc-shaped surface is provided at the position where the two concave templates 31 first come into contact with the stainless steel substrate during the downward movement of the two concave templates 31, thereby reducing the pressure when the two come into contact.

[0053] In one embodiment of this application, such as Figure 2 As shown, the distance between the shaft and the upper surface of the concave template 31 is greater than the distance between the shaft and the lower surface of the concave template 31.

[0054] Specifically, the concave template 31 interacts with the stainless steel substrate, causing the stainless steel substrate to bend until the bent part contacts the part near the shaft. As the concave template 31 moves downward, it begins to rotate. With the shaft as the fulcrum, the distance between the bent part of the stainless steel substrate and the contact position of the concave template 31 and the shaft is regarded as the dynamic rod, and the distance between the shaft and the lower surface of the concave template 31 is regarded as the resistance rod. With the resistance rod remaining constant, the length of the dynamic rod gradually increases.

[0055] Furthermore, because the distance between the shaft and the upper surface of the concave template 31 is greater than the distance between the shaft and the lower surface of the concave template 31, the process of gradually increasing the length of the power rod quickly changes from a force-intensive lever structure to a force-saving lever structure. Therefore, a larger force can be obtained when the stainless steel substrate is formed in the later stage, further avoiding the risk of cracking caused by instantaneous distance deformation.

[0056] In one embodiment of this application, such as Figure 3 As shown, the punching mechanism 4 also includes a fixed frame 42, a first cylinder 43, and a guide rail 44.

[0057] Multiple cutting tools 41 are equidistantly mounted on a fixed frame 42. A first cylinder 43 and a guide rail 44 are respectively mounted on a platform 1. The output end of the first cylinder 43 is connected to the fixed frame 42, and the fixed frame 42 is slidably connected to the guide rail 44.

[0058] It should be noted that the cutting tool 41 and the fixing frame 42 described in this embodiment are connected in a detachable manner, which facilitates the replacement and adjustment of the cutting tool 41.

[0059] It is understandable that setting a guide rail 44 between the fixed frame 42 and the platform 1 can ensure the stability of the fixed frame 42 and the tool 41 during movement.

[0060] In one embodiment of this application, such as Figure 4 and Figure 5As shown, the positioning component 22 includes a base 222, an electric telescopic rod 223, and an autonomous telescopic component 224.

[0061] The base 222 is set on the frame 1, the electric telescopic rod 223 is installed on the base 222, the punch 21 is provided with a guide groove 221, the self-expanding component 224 is slidably set inside the guide groove 221, the output end of the electric telescopic rod 223 is connected to the self-expanding component 224, and the stainless steel substrate to be processed abuts against the self-expanding component 224.

[0062] It should be noted that the autonomous telescopic component 224 described in this embodiment is a square sleeve structure with an internal spring. Its specific connection structure and working principle have been disclosed in the prior art, so they will not be described in detail here.

[0063] The self-extending component 224 is in an extended state in a free state, and the stainless steel substrate is in contact with the self-extending component 224. During stamping, the self-extending component 224 can retract, thereby avoiding interference with the stamping mechanism 3.

[0064] In one embodiment of this application, such as Figure 4 and Figure 5 As shown, an infrared alignment device 225 is provided on a base 222.

[0065] Specifically, before the relevant technicians place the stainless steel substrate on the punch 21, the relevant technicians can mark the middle position of the stainless steel substrate. Then, when it is placed on the punch 21, the infrared light emitted by the infrared alignment instrument 225 is made to coincide with the marked position, that is, to ensure that the stainless steel substrate is located directly above the punch 21.

[0066] The electric telescopic rod 223 pushes the self-extension component 224 to abut against the edge of the stainless steel substrate, thereby fixing the stainless steel substrate.

[0067] In one embodiment of this application, such as Figure 4 As shown, the top material mechanism 5 is located below the shaping mechanism 2. The top material mechanism 5 includes a second cylinder 51, a carrier plate 52, and two top material rods 53.

[0068] The second cylinder 51 is mounted on the frame 1, the carrier plate 52 is connected to the output end of the second cylinder 51, and two ejector rods 53 are symmetrically arranged on the carrier plate 52. One end of the ejector rod 53 passes through the upper surface of the frame 1 and the punch 21 in sequence, and is slidably connected to the frame 1 and the punch 21.

[0069] Specifically, after the stainless steel buckle is processed, it is snapped onto the punch 21. At that time, the second cylinder 51 pushes the carrier plate 52 to move, and the carrier plate 52 pushes the two ejector rods 53 to act on the stainless steel buckle, so that the two are separated, making it convenient for relevant technicians to remove the stainless steel buckle.

[0070] In one embodiment of this application, such as Figure 6 As shown, multiple cutting tools 41 are arranged in a stepped structure, and the cutting edge of each cutting tool 41 is provided with an angled edge 61.

[0071] It is understandable that the multiple cutting tools 41 are arranged in a stepped structure, so that when the first cylinder 43 pushes the multiple cutting tools 41 to move together, the multiple cutting tools 41 act on the stainless steel substrate in sequence to obtain a larger force.

[0072] The cutting edge of the tool 41 is provided with a bevel angle 61. When the tool 41 interacts with the stainless steel substrate, it can not only obtain a greater force, but also prevent scrap from getting stuck inside the tool 41.

[0073] In summary, the stainless steel buckle processing device of this application first precisely bends the substrate through the stamping mechanism, and then completes the punching operation at the same station, which improves the overall processing efficiency. During the punching process, the stamping mechanism and the punch cooperate with each other to play a clamping and positioning role, effectively fixing the substrate, and providing sufficient support to the area around the hole during punching, thereby preventing the connecting hole from deforming and ensuring stable forming quality.
