Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flip-punching devices, and in particular to a novel flip-punching device. Background Technology
[0002] The new flip-punching device is a piece of equipment used for metal processing or material forming. It forms holes on the surface of materials by punching and combines a flipping structure to achieve multi-angle or double-sided processing, reducing repetitive positioning steps and improving efficiency.
[0003] Currently, since the parts have a negative angle, the first four forming and shaping processes can be automated by placing the parts at an angle to achieve robotic production. However, the final punching die structure must be upright (due to the limitations of the first four die structures, oblique punching cannot be used). Therefore, the fourth process has to be done offline manually, which wastes manpower and stamping equipment resources. Manual punching also increases the risk of missing processes. Therefore, we propose a new type of flipping punching device. Utility Model Content
[0004] In view of the problem that existing end effectors cannot measure the rotation angle of a single part, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a new type of flipping punching device, which aims to compensate for the inability of the end effector to rotate a single piece by a flipping mechanism, thereby achieving automated production.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A novel flip-punching device includes a mold body, a flip base fixed on the mold body, and a flip shaft mounting bracket. A flip shaft and a flip bearing are mounted on the flip base. The flip shaft is connected to a flip die seat. A return spring is provided below the flip die seat. The flip shaft and the flip bearing are fixed by a cover plate. The contact surfaces of the flip die seat and the flip base are respectively provided with mutually cooperating limiting surfaces for positioning and locking during punching.
[0008] As a technical solution of the novel flipping punching device of this utility model, the flipping base is rigidly connected to the mold body by high-strength bolts, and the limiting surface of the flipping base is a 45° inclined surface structure that has been hardened by quenching, forming a full contact lock with the limiting surface of the flipping die seat.
[0009] As a technical solution of the novel flipping punching device of this utility model, the two ends of the flipping shaft are axially positioned by the flipping shaft mounting bracket, and the connection between the flipping shaft and the flipping die seat is provided with a keyway fit structure, and the keyway is filled with a wear-resistant copper bushing.
[0010] As a technical solution of the novel flipping punching device of this utility model, the return spring is a double-strand parallel compression spring, the bottom end of which is fixed on the mold body by an adjustable spring seat, and the top end is embedded in the annular groove at the bottom of the flipping die seat, and the annular groove is provided with a spring anti-disengagement buckle.
[0011] As a technical solution of the novel flip-punching device of this utility model, the cover plate is fixed on the flip base by four sets of symmetrically distributed countersunk screws, and the inner side of the cover plate is provided with a stepped annular groove that is interference-fitted with the outer ring of the flip bearing.
[0012] As a technical solution of the novel flipping punching device of this utility model, when the limiting surface of the flipping die holder is in contact with the limiting surface of the flipping base, the contact area between the two is ≥85%, and the working surface of the flipping die holder is perpendicular to the punch axis of the die body in the punching state.
[0013] Compared with the prior art, the present invention has at least the following beneficial effects:
[0014] 1. This utility model combines the two processes of "positioning-punching" in traditional punching dies into one step through a flipping mechanism. It enables different functions to be achieved by picking up parts and punching them at different angles, avoiding the offline punching, missed processes and outflows of the original process. It also reduces the number of punching times, punching personnel, and personnel for visual inspection of holes, ensuring the quality stability of continuous product production.
[0015] 2. This utility model, through the high-precision fit of the limiting surface and the wear-resistant design of the flipping shaft, can improve the accuracy and reliability of the punching position, and at the same time improve the product qualification rate.
[0016] 3. This utility model, through quenching and hardening of the limiting surface, can reduce the wear of key components and reduce maintenance costs. Attached Figure Description

[0028] Reference Figures 1-4A novel flip-punching device is provided, comprising a mold body 1, a flip base 2 fixed on the mold body 1, and a flip shaft mounting bracket 3. A flip shaft 4 and a flip bearing 5 are mounted on the flip base 2. The flip shaft 4 is connected to a flip die seat 6. A return spring is provided below the flip die seat 6. The flip shaft 4 and the flip bearing 5 are fixed by a cover plate 7. The contact surfaces of the flip die seat 6 and the flip base 2 are respectively provided with mutually cooperating limiting surfaces to achieve positioning and locking during punching. In application, the flip mechanism realizes the automatic flipping and resetting of the flip die seat 6, replacing manual adjustment of the transmission, reducing manual intervention, and ensuring punching accuracy.
[0029] Reference Figure 2 and Figure 4 The flip base 2 is rigidly connected to the mold body 1 by high-strength bolts, and the limiting surface of the flip base 2 is a 45° inclined surface structure that has been hardened by quenching, forming a full contact lock with the limiting surface of the flip die seat 6, which improves the impact resistance of the flip base 2, extends the service life of the limiting surface, and prevents wear and deformation caused by long-term stamping.
[0030] Reference Figures 1-4 The two ends of the flip shaft 4 are axially positioned by the flip shaft mounting bracket 3, and the connection between the flip shaft 4 and the flip die seat 6 is provided with a keyway fit structure. The keyway is filled with wear-resistant copper bushing to ensure stable force transmission between the flip shaft 4 and the flip die seat 6, reduce wear gaps, and avoid punching misalignment caused by rotation deviation.
[0031] Reference Figure 2 and Figure 4 The return spring is a double-stranded compression spring. Its bottom end is fixed to the mold body 1 through an adjustable spring seat, and its top end is embedded in the annular groove at the bottom of the flipping die seat 6. The annular groove is equipped with a spring anti-disengagement buckle to enhance the reliability of reset, prevent the spring from falling off or failing on one side, and ensure the stability of continuous production.
[0032] Reference Figure 1 and Figure 4 The cover plate 7 is fixed to the flip base 2 by four sets of symmetrically distributed countersunk screws. The inner side of the cover plate 7 is provided with a stepped annular groove that is interference-fitted with the outer ring of the flip bearing 5, which optimizes the fixing effect of the flip bearing 5, avoids the flip shaft 4 from shifting due to the loosening of the flip bearing 5, and reduces the maintenance frequency.
[0033] Reference Figures 1-4 When the limiting surface of the flip die holder 6 is in contact with the limiting surface of the flip base 2, the contact area between the two is ≥85%, and the working surface of the flip die holder 6 is set perpendicular to the punch axis of the mold body 1 in the punching state, so as to ensure that the flip die holder 6 and the punch are accurately aligned during punching, thereby reducing burrs and scrap rate.
[0034] The working principle of this utility model is as follows: part positioning and loading, specifically, the end effector uses a vacuum suction cup to accurately place the part to be punched on the positioning surface of the flip die base 6, so as to ensure that the edge of the part fits with the limiting block of the flip die base 6;
[0035] The mold pre-closing start is specifically achieved by the punch press driving the upper mold to move downward and applying pressure to the flipping die holder 6. At this time, the return spring is in the initial compression state.
[0036] The flip die holder 6 is flipped and locked. Specifically, under its continuous pressure, the flip die holder 6 rotates 45° counterclockwise around the flip axis 4 until its limiting surface is completely in contact with the quenched and hardened limiting surface of the flip base 2. At this time, rigid fixation is achieved through the inclined self-locking mechanism.
[0037] Vertical alignment punching, specifically, the punch press continues to move downwards, and the punch punches along the axis perpendicular to the working surface of the flipping die base 6. The punching force is evenly transmitted to the flipping base 2 through the limiting surface to complete the hole processing.
[0038] Spring-driven reset: When the punch press moves upward, the return spring releases its stored energy, pushing the flipping die holder 6 to rotate 45° clockwise to reset to the material taking angle. At the same time, the punching waste is ejected from the flipping die holder 6.
[0039] The finished product removal cycle involves the end effector removing the punched part, and the punch press entering the next work cycle. The entire process does not require manual adjustment of the die angle, thus achieving punching automation. At the same time, it combines two processes into one, which can reduce die maintenance costs and reduce the number of punches per product.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
