Description

Technical Field

[0001] This application relates to the field of stamping die technology, and in particular to a spring bar stamping die. Background Technology

[0002] As a structural component with elastic restoring function, elastic spring clips are widely used in various fields such as automotive parts and vibration damping of mechanical equipment. However, existing elastic spring clip stamping dies have several shortcomings in actual production: First, the blank sheet is often conveyed manually or by simple roller guidance, which can easily lead to misalignment during conveying, resulting in inaccurate stamping positions and reduced product qualification rates. Second, the guiding accuracy of the stamping components is insufficient during reciprocating motion, easily causing lateral sway, which not only affects the service life of the stamping cutter but also causes deviations in the spring clip forming dimensions. Third, the stamped spring clips usually fall directly under the die, requiring regular manual cleaning and collection, increasing the labor intensity of operators. Utility Model Content

[0003] This utility model is mainly aimed at addressing the above-mentioned problems existing in the prior art, and provides a spring bar stamping forming mold.

[0004] The objective of this utility model is mainly achieved through the following solution: A spring bar stamping die includes an operating table, a base mounted on the operating table, a support rod provided on the rear side of the upper surface of the base, a support platform mounted on the top of the support rod, and a stamping assembly mounted on the support platform. A first telescopic component is also installed on the rear side of the upper surface of the base. A support plate is installed on the telescopic end of the first telescopic component. A conveying component is installed on the support plate. A stamping hole is opened on the upper surface of the support plate below the stamping component. A receiving component installed on the base is also provided below the support plate.

[0005] Preferably, the stamping assembly includes a second telescopic assembly mounted on the upper surface of the support platform. The telescopic end of the second telescopic assembly passes through the upper surface of the support platform and is fixedly connected to a mounting plate.

[0006] Preferably, the upper surface of the mounting plate is provided with a vertical guide rod, the top of which passes through the upper surface of the support platform, and a linear bearing is embedded in the support platform, with the vertical guide rod passing through the linear bearing and slidably connected to it.

[0007] Preferably, the conveying assembly is provided with a plurality of conveying rollers in sequence along the moving direction of the blank plate. One end of the conveying roller is rotatably connected to the side wall of the support plate. The blank plate is located between the conveying roller and the upper surface of the support plate. A drive motor is installed on the support plate. The output end of the drive motor is fixedly connected to one end of the conveying roller near the punching hole.

[0008] Preferably, the receiving assembly includes a receiving plate, and a receiving groove is formed on the upper surface of the receiving plate at a position corresponding to the stamping hole. The receiving groove is open at the front and inclined, and the front side of the receiving groove is lower than the rear side of the receiving groove.

[0009] Preferably, guide plates are symmetrically arranged on the left and right edges of the front side of the receiving groove, and a vertically arranged baffle is installed on the front side of the base by locking bolts. The distance between the baffle and the front side of the receiving plate is the length of the forming elastic strip.

[0010] In summary, compared with the prior art, the present invention has the following beneficial technical effects: (1) By setting up a conveying assembly consisting of a drive motor and a conveying roller, and with the control of a stepper motor, this utility model can realize the intermittent and precise conveying of the blank plate, effectively avoiding the positional deviation caused by manual pushing; at the same time, the rubber anti-slip layer on the outer surface of the conveying roller further improves the stability of the conveying process, ensuring that the blank plate can be accurately aligned with the punching hole each time it is punched, which significantly improves the dimensional accuracy and pass rate of the product. (2) The vertical guide rod and linear bearing structure set in the stamping assembly of this utility model provide high-precision guidance for the up and down movement of the stamping cutter head, effectively limiting the lateral sway during the stamping process and ensuring that the stamping cutter head always applies force in the vertical direction; at the same time, the second telescopic assembly uses a servo hydraulic cylinder, which can realize precise control of stamping force and stamping speed, reduce the problem of elastic deformation caused by stamping stress concentration, and extend the service life of the stamping cutter head; (3) By setting up a receiving assembly consisting of an inclined receiving groove, a guide plate and a baffle, the stamped elastic bar can automatically fall into the receiving groove under the action of gravity and slide down along the inclined surface. After being guided by the guide plate, it is neatly arranged at the baffle, eliminating the need for manual cleaning in real time and reducing the labor intensity of operators.

Detailed Implementation

[0013] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0014] like Figure 1-5 As shown, this utility model discloses a technical solution: a spring clip stamping forming mold, including an operating table 1. A base 2 is fixedly installed on the operating table 1 by bolts. The base 2 serves as the mounting foundation for the various functional components of the mold and is made of high-strength cast iron to ensure sufficient load-bearing capacity and stability. A support rod 3 is integrally formed or fixedly installed by bolts on the rear side of the upper surface of the base 2. Two support rods 3 are symmetrically distributed, and a horizontally arranged support platform 4 is installed on their tops by welding or flange connection. A stamping component for realizing the spring clip stamping is installed on the support platform 4.

[0015] On the rear side of the upper surface of the base 2, between the two support rods 3, a first telescopic component 5 is fixedly installed by bolts. The first telescopic component 5 is a hydraulic telescopic cylinder or a pneumatic telescopic cylinder, with its telescopic end set vertically upward and fixedly connected to a support plate 6 by bolts. The support plate 6 is made of No. 45 steel plate after quenching and tempering, which has good strength and wear resistance. A conveying component for conveying the blank plate is installed on its upper surface, and a stamping hole 7 matching the forming size of the elastic bar is opened on the upper surface of the support plate 6 directly below the stamping component. The edges of the stamping hole 7 are rounded to avoid scratching the blank plate during the stamping process. A receiving component installed on the base 2 is also provided below the support plate 6 to receive the stamped elastic bar.

[0016] Specifically, the stamping assembly includes a second telescopic assembly 8 that is fixedly installed on the upper surface of the support platform 4 by bolts. The second telescopic assembly 8 is preferably a servo hydraulic cylinder. Its telescopic end passes through the preset mounting hole on the support platform 4 and is fixedly connected to the mounting plate 9. The lower surface of the mounting plate 9 is precisely installed with a stamping cutter head 10 by positioning pins and bolts. The stamping cutter head 10 is made of high-speed steel and has an inclined surface 11 at its bottom. The inclination angle of the inclined surface 11 is set to 30°-60° according to the forming requirements of the spring strip to ensure that the blank can be smoothly formed along the inclined surface during the stamping process and reduce the concentration of stamping stress.

[0017] To improve the motion accuracy of the stamping assembly, two vertical guide rods 12 are symmetrically arranged on the upper surface of the mounting plate 9. The top of the vertical guide rods 12 passes through corresponding guide holes on the support platform 4, and a linear bearing 13 is embedded in the guide hole on the support platform 4. The vertical guide rods 12 pass through the linear bearings 13 and are slidably connected to them. The linear bearings 13 are high-precision ball linear bearings, which can effectively reduce the friction during the movement of the vertical guide rods 12, ensuring that the stamping cutter head 10 always moves in the vertical direction and avoiding lateral deviation.

[0018] The conveying assembly has multiple conveying rollers 15 arranged sequentially along the moving direction of the blank plate 14. The outer surface of the conveying rollers 15 is covered with a rubber anti-slip layer, and one end of each roller is rotatably connected to the side wall of the support plate 6 via a deep groove ball bearing. The blank plate 14 is located between the conveying rollers 15 and the upper surface of the support plate 6, and a drive motor 16 is mounted on the side wall of the support plate 6 via a motor bracket. The drive motor 16 is a stepper motor, and its output end is fixedly connected to one end of the conveying roller 15 near the punching hole 7. By driving the conveying rollers 15 to rotate through the drive motor 16, precise intermittent conveying of the blank plate 14 can be achieved, ensuring that the processing position of the blank plate 14 is accurately aligned with the punching hole 7 during each punching.

[0019] The receiving assembly includes a receiving plate 17 fixed to the base 2 by bolts. A receiving groove 18 is provided on the upper surface of the receiving plate 17 at the position corresponding to the stamping hole 7. The cross-sectional shape of the receiving groove 18 matches the cross-sectional shape of the forming elastic strip 22. The front side of the receiving groove 18 is open and inclined. The front side of the receiving groove 18 is lower than the rear side of the receiving groove 18. The inclination angle is set to 15°-25° to facilitate the forming elastic strip 22 to slide forward automatically under the action of gravity.

[0020] To prevent the elastic clips from shifting during their descent, guide plates 19 are symmetrically arranged on the left and right edges of the front side of the receiving groove 18. The guide plates 19 are bonded or bolted to the receiving groove 18, and their spacing matches the width of the formed elastic clips 22. Furthermore, a vertically arranged baffle 21 is installed on the front side of the base 2 via locking bolts 20. The baffle 21 is made of rubber and effectively cushions the impact of the elastic clips. The distance between the baffle 21 and the front side of the receiving plate 17 is the length of the formed elastic clips 22, ensuring that the clips are neatly arranged after sliding to the baffle 21 for easy collection later.

[0021] When using this spring clip stamping die, firstly, based on the thickness of the blank plate 14 and the forming requirements of the spring clip, the height of the support plate 6 is adjusted via the first telescopic component 5 so that the distance between the conveying roller 15 and the upper surface of the support plate 6 is slightly greater than the thickness of the blank plate 14, ensuring that the blank plate 14 can be conveyed smoothly without shaking. Then, the blank plate 14 is placed at the input end of the conveying component, and the drive motor 16 is started. The drive motor 16 drives the conveying roller 15 to rotate, conveying the blank plate 14 towards the stamping hole 7. When the blank plate 14 is moved to the position to be processed directly above the stamping hole 7, the drive motor 16 stops working, and the blank plate 14 is positioned.

[0022] Next, the second telescopic component 8 is activated, its telescopic end extending downwards, driving the mounting plate 9 and the stamping cutter head 10 to move vertically downwards along the guide mechanism composed of the vertical guide rod 12 and the linear bearing 13. The inclined surface 11 at the bottom of the stamping cutter head 10 acts on the blank plate 14, and the spring strip is stamped through the cooperation of the stamping hole 7. After stamping is completed, the second telescopic component 8 drives the stamping cutter head 10 to return to its original position, and at the same time, the drive motor 16 is started again, conveying the blank plate 14 forward one station. The stamped spring strip falls from the stamping hole 7 into the receiving groove 18 of the receiving plate 17 below, and slides forward along the inclined receiving groove 18 under the action of gravity. Under the guidance of the guide plate 19, it moves accurately to the baffle 21, completing one stamping and receiving process. By repeating the above steps, continuous batch production of spring strips can be achieved.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
