Technical Field
[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping device for producing decorative covers. Background Technology
[0002] Decorative covers are accessories used to cover, beautify, or protect certain components or interfaces, and are commonly used in home furnishings, industry, automobiles, and electronic devices. They not only enhance the aesthetic appearance of products but also provide protection against dust, water, and corrosion. Most metal decorative covers are manufactured using stamping technology.
[0003] When using existing stamping equipment to manufacture decorative covers, the covers are often small and lightweight, causing them to become stuck in the lower die, making removal difficult and hindering work efficiency. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a stamping device for producing decorative covers, which overcomes the deficiencies of existing technologies and effectively solves the problem that, due to the small size and light weight of decorative covers, the stamped decorative covers are easily embedded in the lower mold, making them difficult to remove and hindering work efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A stamping device for producing decorative covers includes an upper die base, an upper clamping plate fixed to the bottom of the upper die base, an upper template fixed to the bottom of the upper clamping plate, a lower stripping plate below the upper template, a lower pad plate below the lower stripping plate, a lower die base connected to the bottom of the lower pad plate, and lower pad feet evenly distributed at intervals connected to the bottom of the lower die base, a lower support plate connected to the bottom of the lower pad feet, and nitrogen springs connected to both ends of the top of the lower support plate, with push rods connected to the tops of the two nitrogen springs, and limit blocks connected to the tops of the push rods.
[0007] When the upper mold base is pressed downward by the hydraulic push rod, the upper mold plate and the lower ejector plate abut against each other. After contact, as the upper mold plate continues to press down, the lower cutting edge of the lower ejector plate and the upper cutting edge of the upper mold plate interlock together. With the pressing of the pin, the decorative cover is formed between the stretching punch and the inner groove. The resulting downward pressure is transmitted from the lower ejector plate to the nitrogen spring through the ejector rod. The nitrogen spring is compressed and contracts to buffer and dampen the impact force. When the upper mold base moves away from the lower ejector plate, the nitrogen spring recovers and drives the ejector rod to push upward, causing the decorative cover to pop up and making it easier to demold.
[0008] Preferably, a hydraulic push rod is connected to the top of the upper mold base, and a fixing frame is connected to the top of the hydraulic push rod.
[0009] The upper mold base is moved up and down by a hydraulic push rod, and the hydraulic push rod is installed and fixed by a fixed frame.
[0010] Preferably, the top two ends of the lower support plate are provided with grooves, and the bottom of the nitrogen spring is inserted into the groove.
[0011] The grooves allow the nitrogen spring to be stably attached to the top of the lower support plate.
[0012] Preferably, both the lower pad and the lower mold base have through holes at their tops, and the through holes are inserted into the ejector rods.
[0013] The ejector pin moves up and down along the through hole within the lower pad and lower mold base, working in conjunction with the nitrogen spring below to provide a buffering function.
[0014] Preferably, the lower stripper has openings at both ends of its top, and a lower cutting edge is fixed at each opening. A stretching punch is inserted into the lower cutting edge and a cutting edge pad is provided at the bottom of the lower cutting edge.
[0015] The decorative cover is shaped by the lower cutting edge in conjunction with the stretching punch, and the cutting edge pad can support the bottom of the lower cutting edge.
[0016] Preferably, the bottom of the upper template is provided with mounting grooves at both ends, and the inner wall of the mounting groove is fixed with an upper cutting edge whose inner diameter is equal to the outer diameter of the lower cutting edge. The inner wall of the upper cutting edge is provided with a tension ring, and the bottom of the tension ring is provided with an inner groove. A pin fixed to the bottom of the upper clamping plate is provided in the inner groove.
[0017] The decorative cover is stamped and formed by the upper and lower cutting edges, and the stretching ring and inner groove cooperate to facilitate the demolding of the decorative cover.
[0018] The beneficial effects of this utility model are as follows:
[0019] When the upper die is pressed downward by the hydraulic push rod, the upper cutting edge of the upper die plate and the lower cutting edge of the lower stripper plate align with each other, forming the decorative cover between the stretching punch and the inner stripper groove. The resulting downward pressure is transmitted to the nitrogen spring through the ejector rod, and the nitrogen spring is compressed and contracted to buffer and dampen the impact force. When the upper die is moved away from the lower stripper plate below, the nitrogen spring recovers and drives the ejector rod to push upward, causing the decorative cover to pop out upward, which facilitates the demolding of the decorative cover. This effectively solves the problem in the existing technology that the decorative cover is often small and light, which makes it easy for the stamped decorative cover to be embedded in the lower die, resulting in difficulty in removal and hindering the improvement of work efficiency.
