Description

Technical Field

[0001] This utility model relates to the field of automatic manufacturing equipment technology, and in particular to a fastener forming equipment for hardware manufacturing. Background Technology

[0002] In the hardware manufacturing industry, gaskets, as a common fastening auxiliary component, are widely used in mechanical assembly, pipe connections, electronic equipment, and building structures. They are mainly used to distribute loads, prevent loosening, compensate for gaps, or provide seals. Depending on the application, gaskets often need to have specific cross-sectional shapes (such as circular, rectangular, corrugated, serrated, or irregular contours), and have high requirements for thickness uniformity, edge flatness, and dimensional consistency.

[0003] Traditional gasket manufacturing often employs stamping processes, where metal sheets are punched and formed in a single pass using a die. While this method is suitable for mass production of gaskets with simple shapes, it suffers from significant material waste, high die costs, and difficulty in controlling springback when processing gaskets with complex cross-sections or gradually changing contours. Furthermore, for long, continuous gaskets or special structural gaskets requiring multi-pass progressive forming, traditional stamping processes struggle to meet the demands of continuous, high-precision production.

[0004] Roll forming technology, due to its ability to achieve continuous and progressive plastic deformation of metal strips, has been increasingly applied to the manufacturing of gasket-type parts in recent years. By setting up multiple sequentially arranged roll forming modules, each module applies specific local deformation to the strip, ultimately accumulating to form the target cross-sectional shape. However, in actual roll forming processes, as the cross-sectional shape of the strip continuously changes, without a transitional guiding structure matching the current forming state, phenomena such as strip deviation, warping, twisting, and even jamming can easily occur, severely affecting forming accuracy and equipment operational stability.

[0005] Especially for thin-walled or high aspect ratio gaskets, their rigidity is low after rolling, making them more susceptible to external interference and deviation from the predetermined trajectory. Existing equipment usually relies solely on the positioning function of the rollers themselves or uses general-purpose guide plates for material conveying, failing to provide adaptive guidance for the cross-sectional characteristics of each rolling stage. This results in poor connection between processes, significant cumulative errors, and difficulty in ensuring the consistency of the gasket edge contour and overall straightness.

[0006] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a fastener forming equipment for hardware manufacturing, which can solve one or more problems existing in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a fastener forming equipment for hardware manufacturing, comprising a main frame, a guide plate, a guide groove, and multiple roller pressing modules arranged sequentially along the material conveying direction; The roll forming module includes a convex roller shaft and a concave roller shaft arranged parallel to each other, and a roll forming gap is formed between the convex roller shaft and the concave roller shaft for roll forming. Each of the roller pressing modules has a guide plate at its discharge end. The guide plate has an inwardly recessed guide groove. The cross-sectional shape of the guide groove is adapted to the roller pressing gap of the corresponding roller pressing module, so as to guide the material after roller pressing to smoothly enter the next process.

[0009] In one embodiment of the present invention, a drive motor and a belt guide plate are also provided on the main frame. The drive motor is located below the roller pressing module and is connected to the roller pressing module through a transmission belt. The belt guide plate is provided with an opening groove, and the transmission belt passes through the opening groove.

[0010] In one embodiment of the present invention, the concave roller shaft is provided with a driving gear, the convex roller shaft is provided with a driven gear, the driving gear and the driven gear are connected by a synchronous belt, and the transmission belt is connected to the driving gear for transmission.

[0011] In one embodiment of the present invention, a fixed gear and a tensioning gear are provided on the main frame, and the fixed gear and the tensioning gear respectively mesh with the synchronous belt.

[0012] In one embodiment of the present invention, a signal connection controller and a control panel are further included. The control panel is located on the side of the main frame, and the controller is used to control the output power of the drive motor.

[0013] In one embodiment of the present invention, an adjustment channel is hinged to the feed port side of the main frame, and the discharge port of the adjustment channel is set to correspond to the feed port of the roller pressing module.

[0014] In one embodiment of the present invention, the device further includes a mounting shaft and a mounting base. The mounting shaft is mounted on the main frame, and the mounting base is detachably connected to the mounting shaft by bolts. The adjustment channel is mounted on the mounting base.

[0015] In one embodiment of this utility model, an auxiliary wheel is rotatably mounted on the main frame. The auxiliary wheel is located below the adjustment channel and is used to support materials.

[0016] As described above, the fastener forming equipment for hardware manufacturing of this utility model has the following beneficial effects: Through the integrated design of the roller pressing modules and dynamic guiding structure, precise flow and stable forming of materials are achieved during continuous processing. Multiple roller pressing modules supported by the main frame are arranged in an orderly manner along the material conveying direction, allowing the blank to pass through different workstations sequentially for progressive forming, avoiding the accumulation of positioning errors caused by multiple transfers in traditional segmented processing. The guide plate and its contour guide groove at the end of each roller pressing module construct a geometrically continuous channel between the preceding and following processes. This ensures that the material deformed by the previous roller pressing can naturally transition to the subsequent processing area along a preset trajectory, and eliminates the risk of material jamming or displacement through precise matching of cross-sectional shapes. This adaptive guiding mechanism effectively improves the integrity of the forming process and simplifies the equipment debugging process, allowing operators to achieve full-line linkage by adjusting only the parameters of a single module, significantly enhancing the production line's responsiveness to the needs of multi-variety, small-batch production.

[0020] This utility model provides a fastener forming device for hardware manufacturing. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Please see Figure 1 and Figure 2 This utility model provides a fastener forming device for hardware manufacturing, including a main frame 1, a guide plate 2, a guide groove 3, and multiple roller pressing modules arranged sequentially along the material conveying direction. Each roller pressing module consists of a convex roller shaft 4 and a concave roller shaft 5, which are installed parallel to each other vertically and fixed to the main frame 1 by bearing seats. The surface of the convex roller shaft 4 has a raised forming profile, and the surface of the concave roller shaft 5 has a complementary concave profile. The gap between the two forms the roller pressing gap. On the discharge side of each module, adjacent to the roller pressing gap outlet, a guide plate 2 is fixedly installed. The guide groove 3 on the guide plate 2 is a through groove that penetrates the plate body, and its groove shape is the cross-section of the roller pressing gap of the previous process. For example, if the material cross-section becomes a "T" shape with ribs after passing through the roller pressing module, then the cross-section of the guide groove 3 is a "T" shaped recess that perfectly matches it. In this way, once the material leaves the roller pressing module, its formed part is immediately embedded in the guide groove 3, and slides smoothly under the constraint of the groove wall of the guide groove 3, and is accurately guided to the entrance of the next roller pressing module.

[0022] The drive motor 6 is mounted on a base inside or below the main frame 1, located below all the roller pressing modules to save space and lower the center of gravity. A drive pulley is mounted on the motor's output shaft. A closed-loop drive belt wraps around the drive pulley and the driven gear 8 on the roller pressing module drive shaft. A belt guide plate 7 is installed on the main frame 1 in the area traversed by the drive belt. The belt guide plate 7 has elongated slots through which the drive belt passes. The belt guide plate 7 serves as protection and isolation, preventing operators or debris from contacting the moving drive belt, while its slots ensure unobstructed operation of the drive belt.

[0023] The concave roller shaft 5 is equipped with a driving gear 8, and the convex roller shaft 4 is equipped with a driven gear 9. A synchronous belt meshes with the driving gear 8 and the driven gear 9 to ensure that the rotation of the concave roller shaft 5 and the convex roller shaft 4 is strictly synchronized and their linear velocities are consistent. Simultaneously, the shaft end of the concave roller shaft 5 is also equipped with a pulley or sprocket for connecting to the transmission belt. The drive motor 6 transmits power to the concave roller shaft 5 of each module via the transmission belt, and the concave roller shaft 5 then drives the convex roller shaft 4 of the same module to rotate synchronously in the opposite direction via the synchronous belt.

[0024] To optimize the transmission stability of the synchronous belt, a fixed gear 10 is installed on the main frame 1. The fixed gear 10 is mounted at a preset position on the main frame 1, and its teeth mesh with the inner side of the synchronous belt, acting as a fixed idler pulley. This allows for changes in the wrap angle or direction of the synchronous belt. A tension gear 11 is also included, mounted on a movable adjusting seat, and its position can be adjusted via bolts or a spring mechanism. The tension gear 11 also meshes with the synchronous belt, adjusting the belt tension by pushing it outwards to compensate for belt elongation after prolonged operation, ensuring tight meshing and reliable transmission.

[0025] A control panel is installed on the side of the main frame 1. The control panel includes a start / stop button, a speed control knob, an emergency stop switch, and status indicator lights. The control panel is electrically connected to a controller 12 installed inside or at the bottom of the main frame 1 via a signal cable. The controller 12 receives commands from the control panel and adjusts the output power or speed of the drive motor 6 in real time, thereby controlling the roller pressing speed to adapt to the processing needs of materials with different materials, thicknesses, or cross-sectional shapes. This control system enables flexible adjustment and safety monitoring of equipment operating parameters, improving operational convenience and process adaptability.

[0026] Please see Figure 2 On the feed inlet side of the main frame 1, an adjustment channel 13 is connected via a hinged structure. The adjustment channel 13 guides the strip material to be processed into the first roller pressing module. Since one end is hinged to the main frame 1, the user can manually adjust the tilt angle or height of the adjustment channel 13 according to the incoming roll diameter, feeding angle, or production line layout requirements, ensuring that its outlet is always precisely aligned with the feed inlet of the first roller pressing module, ensuring smooth material introduction and reducing the risk of initial misalignment. Specifically, it also includes a mounting shaft 14 and a mounting base 15. The mounting shaft 14 is fixed at both ends to support plates on both sides of the main frame 1. The mounting base 15 is fitted onto the mounting shaft 14, and the mounting base 15 has through holes, allowing it to be locked in any position on the mounting shaft 14 by bolts. The adjustment channel 13 is fixed to the mounting base 15 by screws or clips. When it is necessary to replace the adjustment channel 13 of different specifications or to perform maintenance, simply loosen the bolts to remove the mounting base 15 together with the adjustment channel 13 as a whole, which facilitates quick replacement or adjustment and improves the versatility and maintenance efficiency of the equipment.

[0027] Below the regulating channel 13, near its discharge end, an auxiliary wheel 16 is rotatably mounted on the main frame 1. The auxiliary wheel 16 is a smooth metal roller with its axis perpendicular to the material conveying direction. When the strip is fed out of the regulating channel 13, its bottom surface naturally overlaps the circumferential surface of the auxiliary wheel 16. The auxiliary wheel 16 rotates freely with the material movement, providing support and guidance, reducing the sag of the strip before entering the first roller gap, and preventing bending or jamming due to its own weight. It is particularly suitable for feeding thinner or longer overhanging strips, further ensuring the stability and alignment of the feed.

[0028] In summary, the fastener forming equipment for hardware manufacturing of this utility model, through the layout of a main frame 1, a guide plate 2, a guide groove 3, and multiple sequentially arranged roller pressing modules, and the matching roller pressing gap formed by the convex roller shaft 4 and the concave roller shaft 5, and the guide plate 2 with the matching guide groove 3 at the discharge end of each roller pressing module, achieves multiple beneficial effects. It can form a precise and stable guiding constraint on the material after roller pressing by means of the guide groove 3 structure that matches the corresponding roller pressing gap, effectively preventing the material from shifting, warping, or twisting during the conveying process, ensuring that the material smoothly and accurately enters the next process, and significantly improving the stability and continuity of the forming process. On this basis, the structure further ensures the forming accuracy of fasteners, especially gaskets, reduces quality problems such as dimensional deviations and surface defects caused by material conveying deviations, and improves the product qualification rate. Meanwhile, the adaptable guiding structure eliminates the need for frequent replacement of guide components, accommodating the gap requirements of different rolling processes. This enhances the equipment's versatility for producing fasteners of various specifications, reduces equipment debugging time and production costs, and ultimately improves overall production efficiency, providing a reliable guarantee for large-scale, multi-variety fastener production. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0029] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
