Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment technology, and specifically relates to a high-efficiency molding groove mechanism. Background Technology

[0002] A molding groove device is a specialized piece of equipment that uses mechanical pressure to press specific shaped grooves onto the surface of a material. It is widely used in metal processing, plastic molding, and composite material manufacturing. Through the coordinated action of the upper and lower molding components, continuous or discontinuous groove structures are pressed onto the surface of sheet metal, pipes, or profiles.

[0003] Traditional molding groove mechanisms have poor stability, and gaps are easily generated at the connection points, which can lead to shaking after long-term use. The single-row roller design means that only one groove can be processed in each molding stroke, resulting in low horizontal pressing efficiency and limited production progress. In addition, the traditional pressing block adopts an integral design, and the entire pressing block needs to be replaced when local wear occurs, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency molding groove mechanism, including: an adjustment mechanism, which is fixed to the side wall of the grooving machine by a dovetail support plate, and is divided into an upper adjustment device and a lower adjustment device; the upper and lower ends of the dovetail support plate are equipped with an upper ball screw assembly and a lower ball screw assembly by fixing plates, and the surfaces of the upper ball screw assembly and the lower ball screw assembly are respectively fixed with an upper horizontal plate and a lower horizontal plate by sliding blocks.

[0005] Preferably, the device also includes a molding device, which includes an upper pressing block and a lower pressing block. Both the upper pressing block and the lower pressing block are T-shaped structures and are respectively fixedly installed on the surfaces of the upper horizontal plate and the lower horizontal plate.

[0006] Preferably, the lower end of the upper pressing block is movably mounted with a row of upper die pressing rollers via bolt roller bearings, and the top of the lower pressing block is mounted with a row of lower die pressing rollers corresponding one-to-one with the upper die pressing rollers via the bolt roller bearings.

[0007] Preferably, both the upper and lower die pressing rollers have raised pressing grooves on their arc-shaped surfaces.

[0008] The beneficial effects of this utility model are: By using a double ball screw assembly in conjunction with a dovetail support plate, the dovetail structure provides strong support and has a small gap with the sliding block, effectively achieving stability in the adjustment of the upper and lower horizontal plates and reducing dimensional errors between the molding grooves. Through two rows of double-layer molding rollers, bidirectional synchronous molding of the sheet material can be completed in a single stroke, thereby significantly improving molding efficiency. The modular component structure design allows parts to be replaced independently when worn, reducing maintenance costs and improving efficiency.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] like Figures 1 to 3As shown, this embodiment provides a high-efficiency molding groove mechanism, including: an adjustment mechanism 1, which is formed by precision casting of high-strength alloy steel through a dovetail support plate 2 and fixed on the side wall of the grooving machine, and is divided into an upper adjustment device 3 and a lower adjustment device 4; the upper and lower ends of the dovetail support plate 2 are each equipped with an upper ball screw assembly 6 and a lower ball screw assembly 7 through a fixing plate 5, and the upper and lower horizontal plates are driven by servo motors externally connected to the upper ball screw assembly 6 and the lower ball screw assembly 7 to realize the synchronous reverse movement of the upper and lower horizontal plates, ensuring that the parallelism error of the upper and lower pressure blocks during the molding process is ≤0.05mm. The upper horizontal plate 11 and the lower horizontal plate 12 are respectively fixed on the surfaces of the upper ball screw assembly 6 and the lower ball screw assembly 7 through sliding blocks 8.

[0016] The device also includes a molding apparatus, comprising an upper pressing block 9 and a lower pressing block 10. Both the upper pressing block 9 and the lower pressing block 10 are T-shaped structures, made of 42CrMo alloy steel with a tempered finish and a surface hardness of HRC52-56, and are fixedly installed on the surfaces of the upper horizontal plate 11 and the lower horizontal plate 12, respectively. A row of upper molding rollers 13 is movably mounted on the lower end of the upper pressing block 9 via bolt roller bearings. A row of lower molding rollers 14, corresponding one-to-one with the upper molding rollers 13, is mounted on the top of the lower pressing block 10 via bolt roller bearings. Due to the presence of the bolt roller bearings, both the upper molding rollers 13 and the lower molding rollers 14 rotate passively; that is, only the friction of the sheet metal drives the rollers to rotate. This structure reduces the friction between the rollers and the sheet metal through the rotation of the rollers, resulting in uniform, burr-free indentations on the sheet metal surface, eliminating the need for secondary processing. Both the upper die pressing roller 13 and the lower die pressing roller 14 have raised pressing groove blocks 15 on their arc surfaces. The height of the raised parts is optimized to 1.2 mm after molding tests, and the width of the pressing groove is designed to be 6 mm, forming a golden ratio with the thickness of the material to be processed.

[0017] When the mechanism starts, the servo motor drives the lower ball screw assembly 7 to rotate, which in turn drives the lower horizontal plate 12 to rise via the sliding block 8. Simultaneously, the upper adjusting device 3 controls the upper ball screw assembly 6 to descend synchronously via a proportional valve, keeping the gap between the upper and lower molding rollers constant, slightly less than the thickness of the sheet material. At this point, the corresponding transmission device is activated, allowing the sheet material to pass through the gap at a uniform speed. The raised structure of the groove block 15 generates a compressive stress of 300MPa upon contact with the sheet material, forming a standard V-groove on the surface of the sheet material through elastic deformation, with the groove depth accuracy controlled within ±0.1mm. Actual production verification shows that this mechanism is 40% more efficient and 25% less energy-consuming than traditional molding equipment. The rigid support structure of the dovetail support plate 2 effectively suppresses vibration and noise during the molding process, keeping the operating noise ≤75dB. The special raised design of the groove block 15 ensures a natural arc transition at the bottom of the groove, avoiding stress concentration and increasing the product qualification rate to 99.2%. The synchronous control function of the upper and lower adjusting devices expands the adaptability range of sheet materials of different thicknesses to 5-30mm, achieving flexible production needs with multiple uses. All the devices selected in this application (parts whose specific structures are not specified) are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
