Description

Technical Field

[0001] This utility model relates to the technical field of stamping forming equipment, specifically a stamping forming device with a ring-shaped fastener to prevent scratches. Background Technology

[0002] A stamping forming device is a mechanical device that uses a stamping die to apply pressure to metal or other materials, causing them to undergo plastic deformation or separation, thereby obtaining the desired parts. During operation, the die is first installed on the press and its position and pressure are adjusted. Then, the metal material to be processed is placed in the appropriate position of the die. The feeding device precisely feeds the material into the die. The press, driven by an electric motor or other equipment, lowers the punch to impact the material. The metal material undergoes plastic deformation in the die. After processes such as stamping, stretching, and bending, the desired shape of the part is formed. Finally, the unloading device removes the finished part from the die and discharges the waste material. For example, utility model patent CN216655979U discloses a pipe stamping forming device, including a base, a worktable on the top of the base, a frame on the top of the worktable, a hydraulic cylinder vertically mounted on the frame, a mounting plate fixedly connected to the bottom of the hydraulic cylinder, a punch on the bottom of the mounting plate, and a support plate rotatably mounted on the front side of the upper surface of the worktable. This pipe stamping forming device, by using a rotatable support plate, ensures that during processing, the line of the pipe placed on the support plate forms a certain angle with the line of the punch. Because the pipe is placed at an angle, it is not directly squeezed and flattened, but rather a notch is pressed into the side wall of the pipe. The shape of the notch is the same as the cross-section of the punch. This eliminates the need for two-step milling with a milling machine, allowing for one-step stamping forming, resulting in faster processing speed and higher work efficiency. However, in the existing technology, the device lacks a guiding mechanism during use, making it difficult to guide the telescopic rod. This leads to the telescopic rod being prone to misalignment. Furthermore, based on the requirements for the left stationary spring of the electronic component in the development of new industrial relays, and combined with the analysis of on-site assembly anomalies of similar parts, this type of part, due to its relatively thick material (2.4mm) and overall L-shaped (67mm × 68.5mm) unfolded shape, has a significant impact on the tolerance of ±0.05mm between related dimensional chains. Moreover, the tapered insertion surface of the assembly edge requires a slanted structure, which will compress and expand the material outwards, affecting dimensional instability. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a stamping forming device for anti-scratch ring fastening. It solves the problem that when the device is in use, there is no guiding mechanism, and the telescopic rod is not easily guided, which makes it easy for the telescopic rod on the device to deviate. In addition, based on the requirements of the left stationary spring of the electronic component for the development of new industrial relays, and combined with the summary and analysis of the abnormal assembly of similar parts on site, this type of part has a relatively thick material of 2.4mm and unfolds into an L-shape of 67mm*68.5mm. The tolerance between related dimensions is only ±0.05, which has a great impact. Furthermore, the tapered insertion surface of the assembly edge design requires the design of a slanting structure. Slanting will squeeze the material outward and affect the instability of dimensional changes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stamping forming device for anti-scratch ring fastening, comprising a lower die spring assembly and an upper die spring assembly. The upper end of the lower die spring assembly is provided with a layered punching die. The interior of the layered punching die is provided with a step-by-step tilting structure.

A guide sleeve is fixedly connected to the lower end of the fixed plate, and a guide rod is slidably connected inside the guide sleeve. A connecting plate is fixedly connected to the lower end of the guide rod, and a telescopic rod is fixedly connected to the connecting plate. A connecting rod is slidably connected inside the guide sleeve, and a handle is fixedly connected to the connecting rod. A pressure rod is fixedly connected to the connecting rod, and the pressure rod contacts the guide sleeve. An oil inlet is provided inside the guide sleeve. By opening the cover and adding lubricating oil into the oil storage sponge, the oil storage sponge is squeezed, causing the lubricating oil in the oil storage sponge to flow from the oil inlet onto the guide rod. Moving the telescopic rod downward causes the connecting plate and the guide rod to move downward, thereby guiding the telescopic rod and preventing it from shifting.

[0007] Preferably, a sealing sleeve is fixedly fitted inside the guide sleeve, and a guide rod is slidably connected inside the sealing sleeve. By designing the sealing sleeve, the inside of the guide sleeve can be sealed.

[0008] Preferably, the guide sleeve has an elastic locking block inside, which is fixedly connected to the connecting rod. By designing the elastic locking block, the connecting rod can be limited.

[0009] Preferably, the inside of the guide sleeve is in contact with an oil-retaining sponge, which is in contact with the pressure rod. By designing the oil-retaining sponge, it can be used to store lubricating oil.

[0010] Preferably, the guide sleeve has an oil inlet inside, and the inside of the oil inlet is connected to a cover by a thread. By designing the oil inlet, lubricating oil can flow from the oil inlet to the guide rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, through the design of components such as a fixed plate, guide sleeve, guide rod, connecting plate, sealing sleeve, and connecting rod, allows the cover to be opened, and then lubricating oil to be added into the oil storage sponge. Squeezing the oil storage sponge causes the lubricating oil in the oil storage sponge to flow from the oil inlet to the guide rod. Moving the telescopic rod downward causes the connecting plate and guide rod to move downward, thereby guiding the telescopic rod and preventing the telescopic rod on the device from deviating.

[0013] 2. This utility model incorporates components such as a lower mold floating pressure block, a slanting insert, and a stripper plate insert. The triangular pyramidal structure features a slanting design, with the slanting insert having a 32° angle (18.7°) and a plane width increased by ≥5.0mm. This allows material to flow to the gaps, preventing bulging or material thickening. The slanting employs pre-cutting and contour cutting to ensure that the part's pin dimensions are not affected, with a precision cutting tolerance of ±0.05mm. The broaching structure is designed after the slanting to avoid its impact on the broach; the external stripping structure solves the material stripping problem after forming close-range broaches, ensuring key dimensions between broaches. The single-sided broach tube position structure ensures the broach is vertical after broaching, meeting key assembly dimensions. Attached Figure Description
