Description

Technical Field

[0001] The utility model belongs to the technical field of building template forming technology, and particularly relates to an automatic grooving mechanism for high-strength alloy steel angle steel. Background Art

[0002] The high-strength alloy formwork used in cast-in-place buildings includes a side formwork and an angle steel formwork connecting the two side formworks at the corners. The structure of the side formwork can be found in Chinese Patent CN217501015U, in which the U-shaped main panel is an integral structure formed by bending as a whole, and is formed by cold-bending and rolling a high-strength stainless steel plate. Specifically, after the cylindrical alloy steel plate is released by the unwinding machine, the plate is placed between the upper roller group and the lower roller group for rolling. The two sides of the plate are first rolled into a shape with a concave groove and a folded edge to form a side plate through the multi-roller group arranged at intervals. Then, the bend between the side plate and the bottom plate is rolled so that the side plate and the bottom plate are perpendicular to each other to form a side formwork. The rolling process can be found in Chinese Patent CN220161003U.

[0003] The structure of the angle steel template is different from that of the side template. Please refer to the angle steel template and its connection with the side template shown in Chinese patent CN219909979U. During the manufacturing process of the angle steel template, the early process is also to roll out the shape of the edges on both sides with concave grooves and folded edges on the rolling equipment of a multi-roller group. However, the process of symmetrical 90° bending cannot be completed synchronously on the multi-roller group rolling equipment because its overall shape is different from that of the side template and lacks the support of the flat bottom plate on the side template. It is necessary to perform a 90° bend through a special sheet metal bending process after rolling. Due to the long length of the angle steel template, it is difficult to ensure the symmetry of the two sides of the bend along the entire length during the 90° bending operation, and the forming consistency is poor.

[0004] In order to facilitate the 90° bending operation in the sheet metal bending process and improve the consistency of bending forming, a process of drawing a middle bending line and forming a middle bending line that is conducive to bending in the form of grooving is added before the sheet metal bending process. The formation of a middle bending line in the form of grooving is also an independent process and tooling. The secondary positioning and manual grooving processes are time-consuming and labor-intensive, which increases manufacturing costs and prolongs manufacturing time, and needs further improvement and optimization. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an automatic grooving mechanism for high-strength alloy steel angle steels, so as to avoid the inconvenience of bending the middle part during the manufacturing of the angle steel template, facilitate the bending operation after rolling the angle steel template, and improve the quality and efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The automatic grooving mechanism for high-strength alloy steel angle steel includes a frame with a roller connected horizontally to the frame; the upper end of the frame extends upward and is connected to a grooving unit, the grooving unit includes a vertical base plate, and is horizontally connected to the upper end of the frame through the base plate, a tool holder seat is provided on one surface of the base plate, both the base plate and the tool holder seat are higher than the roller, a downward-extending grooving tool is connected to the tool holder seat, the lower end tip of the grooving tool is located directly above the roller, and horizontally located in the middle position of the roller.

[0008] To further improve the above technical solution, the tool holder seat extends in a direction away from the substrate, and the number of the grooving tools is multiple and arranged at intervals along the direction away from the substrate. The lower end tip of each grooving tool has a height difference in the vertical direction and is gradually increasing or decreasing.

[0009] Furthermore, among the multiple grooving tools, the grooving tool located in the middle is located directly above the roller.

[0010] Furthermore, the height of the grooving tool relative to the tool holder body is adjustable.

[0011] Furthermore, a vertical tool mounting hole is recessed on the lower surface of the tool holder seat, and the grooving tool is vertically slidably arranged in the tool mounting hole. A fastening screw is provided on the lateral side of the tool mounting hole for fastening the grooving tool inserted into the tool mounting hole.

[0012] Furthermore, the height of the tool holder seat relative to the base plate is adjustable.

[0013] Furthermore, the mechanism is formed on a high-strength alloy template multi-roller group rolling equipment, between any two rolling roller groups.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model's automatic grooving mechanism for high-strength alloy steel angles can be installed on multi-roller rolling equipment for high-strength alloy templates. Between any two roller groups, a grooving mechanism is formed during the rolling process for subsequent bending.

[0016] 2. The grooving unit of the present invention adopts a multi-grooving tool form, so that the grooving process is gradually deepened, effectively avoiding excessive force to damage the alloy steel plate or excessive grooving to affect the subsequent use strength; it is easy to adjust and reliable to use.

[0022] Among them, there are a frame 1, a roller 2, a grooving unit 3, a base plate 31, a tool holder base 32, a grooving tool 33, a fastening screw 34, an alloy steel plate 4, and an angle steel template 5. DETAILED DESCRIPTION

[0023] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] See Figure 1 、 Figure 2 The automatic grooving mechanism for high-strength alloy steel angle steel in a specific embodiment includes a frame 1, to which a rotatable roller 2 is horizontally connected; the upper end of the frame 1 extends upward and is connected to a grooving unit 3, and the grooving unit 3 includes a vertical base plate 31, and is horizontally connected to the upper end of the frame 1 through the base plate 31, and a tool holder seat 32 is provided on the side of the base plate 31 facing the material feeding direction of the roller 2, and the base plate 31 and the tool holder seat 32 are both higher than the roller 2 so that the alloy steel plate conveyed by the roller 2 can pass through, and a grooving tool 33 extending downward is connected to the tool holder seat 32, and the lower end tip of the grooving tool 33 is located directly above the roller 2 so as to process grooves on the alloy steel plate conveyed by the roller 2, and is located in the middle position of the roller 2 in the horizontal direction.

[0025] The automatic grooving mechanism for high-strength alloy steel angle steel in this embodiment can be installed and formed on multi-roller rolling equipment for high-strength alloy templates. Between any two rolling rollers, a grooving groove for subsequent bending is formed immediately during the rolling process, eliminating the need for secondary positioning. The grooving is naturally formed by the forward force of rolling, saving time and effort while improving quality and efficiency. The grooving groove is then used as the central bending line for subsequent bending to form the angle steel template, offering convenient operation, good symmetry, and excellent consistency.

[0026] During operation, the base plate 31 can be fixedly connected to the upper end of the frame 1 by bolting, and the slotting tool 33 can be a planer tool, which is stable and reliable. Figure 3 The tool holder seat 32 extends in a direction away from the base plate 31. The number of the grooving tools 33 can be multiple and spaced apart in the direction away from the base plate 31. In this embodiment, there are three grooving tools 33. The lower end of each grooving tool 33 has a height difference in the vertical direction and is in a gradually increasing and decreasing form. In this embodiment, it is gradually lowered in the direction of discharging. Figure 3 The middle roller 2 rotates clockwise and the alloy steel plate is transported to the right. Correspondingly, the groove marks thrown out are gradually deepened to avoid excessive force damaging the alloy steel plate or excessively deep grooves affecting the subsequent strength of use.

[0027] Among them, among the multiple grooving tools 33, the middle grooving tool 33 is located directly above the roller 2, that is, directly above the axis of the roller 2, opposite to the highest point of the roller 2, reducing the elastic displacement of the alloy steel plate, ensuring that each grooving tool 33 can effectively act on the alloy steel plate, and can effectively ensure that the grooving depth is in place.

[0028] The height of the slotting tool 33 relative to the tool holder base 32 is preferably adjustable. Specifically, a vertical tool mounting hole (not shown) is recessed into the lower surface of the tool holder base 32. The slotting tool 33 slides vertically within the hole. A fastening screw 34 is provided laterally to secure the slotting tool 33 within the hole. As will be appreciated, the side of the tool holder base 32 has an internally threaded hole for threading the fastening screw 34. A countersunk head is typically used to avoid protrusion. To ensure effective fastening, two fastening screws 34 may be provided, spaced vertically apart.

[0029] The height of the tool holder 32 relative to the base plate 31 is preferably adjustable. The slotting cutters 33 are relatively close to the roller 2, making it easier to raise them slightly. After adjusting the vertical height difference between the slotting cutters 33, they are lowered to their intended position. The specific form of the mechanism can be electric drive, pneumatic cylinder drive, or T-slot sliding and fastening connection (not shown), without limitation.

[0030] See Figure 4 、 Figure 5 When in use, the alloy steel plate 4 is rolled by the front roller group to form a concave groove and hem on both sides. When passing through the grooving unit 3, the grooving for bending in the subsequent process is naturally thrown out. It is convenient to use the grooving as the middle bending line to form the angle steel template 5 in the subsequent sheet metal bending.

[0031] During implementation, an annular groove corresponding to the lower tip of the grooving tool 33 can be opened in the middle of the outer circumferential side of the roller 2. During use, it can play the role of appropriate giving way and positioning to avoid left and right deviation movement when the grooving tool 33 acts on the alloy steel plate.

[0032] This mechanism can be modified on the original high-strength alloy template multi-roller rolling equipment on the production line, and can also be implemented on new equipment as a whole, with strong applicability.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
