Description

Technical Field

[0001] This utility model relates to the technical field of profile pressing, and in particular to a positioning structure and profile pressing device. Background Technology

[0002] A profile pressing device is used to press and shape the edges of metal profiles (such as aluminum profiles and steel profiles), and is widely used in construction, automotive, and machinery manufacturing. It conveys the profile to the pressing mechanism via a conveying mechanism, and applies pressure to the profile edges using pressing rollers or pressing dies to form specific shapes or sizes to meet subsequent assembly or usage requirements.

[0003] Existing profile pressing devices typically consist of a frame, a pressing actuator, and an adjustment mechanism. The frame houses an operating table for placing the profile; the pressing actuator usually includes one or more pressing wheels, which are mounted above the operating table via the adjustment mechanism, allowing for fine-tuning of their position along the profile's length or perpendicular to its surface. During processing, movable stops or plates are used to limit the profile's movement. When processing profiles of different specifications, the positions of these stops or plates need frequent changing or adjustment, resulting in cumbersome operation and reduced production efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a positioning structure and profile pressing device that can achieve precise positioning and stable conveying of profiles and improve the quality and efficiency of profile pressing.

[0005] This utility model discloses a positioning structure comprising a frame, uprights, conveying rollers, a drive mechanism, a transmission component, and a protective cover. Two uprights are fixed to the frame in parallel and spaced intervals. Multiple conveying rollers are rotatably connected between the two uprights, with the rollers spaced apart along the length of the uprights and their axial direction perpendicular to the uprights. The outer surface of each conveying roller has a positioning groove with a V-shaped cross-section, the included angle of which corresponds to the profile. The drive mechanism is connected to the multiple conveying rollers via the transmission component. The protective cover covers the drive mechanism and the transmission component.

[0006] As a preferred embodiment of this utility model, the two inclined surfaces of the positioning ring groove are symmetrical.

[0007] As a preferred embodiment of this utility model, the drive mechanism includes a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to multiple conveying rollers through a transmission component.

[0008] As a preferred embodiment of this utility model, the transmission component includes one of multiple pulleys, multiple sprockets, or multiple gears, and a ring-shaped transmission element that cooperates with them.

[0009] As a preferred embodiment of this utility model, a sensor for detecting the position of the profile is provided on the upright plate.

[0010] As a preferred embodiment of this utility model, the cover and the upright plate are connected by a rotating component, a handle is provided on the side of the cover away from the rotating component, and heat dissipation holes are provided on the cover.

[0011] As a preferred embodiment of this utility model, the outer surface of the conveying roller is covered with a rubber layer.

[0012] A profile pressing device, employing the positioning structure of this utility model.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting a positioning ring groove with a V-shaped cross section and an included angle corresponding to the profile on the outer surface of the conveying roller, the profile can be fitted and positioned. The guiding and limiting effect of the V-shaped structure effectively prevents the profile from shifting or shaking during conveying and pressing, ensuring that the profile always moves stably along the preset path and improving positioning accuracy.

[0015] 2. The V-shaped positioning groove of the conveyor roller can be adapted to profiles with right angles. Multiple conveyor rollers rotate synchronously under the drive mechanism and transmission components to realize automated and stable conveying of profiles. When processing right angle profiles of different specifications, there is no need to change them, simplifying the operation process and improving production efficiency. Attached Figure Description

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] like Figures 1 to 2 As shown, this embodiment provides a positioning structure and profile pressing device, including a frame 1, a vertical plate 2, a conveying roller 3, a drive mechanism 4, a transmission component 5, and a protective cover 6. The system comprises two vertical plates 2, which are parallel and fixed to the frame 1 at intervals. Multiple conveying rollers 3 are rotatably connected between the two vertical plates 2, with the rollers spaced apart along the length of the vertical plates 2. The axial direction of the conveying rollers 3 is perpendicular to the vertical plates 2, matching the conveying direction of the profile. A positioning ring groove 31 is provided on the outer surface of the conveying roller 3. The positioning ring groove 31 has a V-shaped cross-section, and the included angle of the V-shape corresponds to the profile. The drive mechanism 4 is connected to the multiple conveying rollers 3 via a transmission component 5, providing power for the rotation of the conveying rollers 3, enabling them to rotate synchronously and thus achieving stable conveying of the profile. A protective cover 6 is installed outside the drive mechanism 4 and the transmission component 5. The protective cover 6 protects the drive mechanism 4 and the transmission component 5, preventing external dust and debris from entering and affecting their normal operation. It also prevents operators from contacting the rotating parts, improving equipment safety. The profiles are mostly right-angled structures, and their cross-sectional edges usually form right-angled sides with a 90° angle. In the profile pressing process, the profile is placed on the conveyor roller 3. When the V-shaped angle matches the angle of the right-angled side of the profile, the two side walls of the right-angled side of the profile can respectively fit with the two side slopes of the V-groove. At this time, the two side slopes of the V-groove will generate symmetrical lateral constraint forces on the right-angled side of the profile, confining the profile in the groove. This not only prevents the profile from deviating along the conveying direction, but also prevents swaying perpendicular to the conveying direction.

[0023] The two inclined surfaces of the positioning ring groove 31 are symmetrical; the symmetrical inclined surfaces can make the two sides of the symmetrical profile receive uniform support and friction, avoiding the profile from twisting or shifting during transportation due to uneven force; for asymmetrical right-angled profiles such as L-shaped profiles, the symmetrical inclined surfaces can also achieve main positioning by fitting the longer right-angled side, and the shorter right-angled side can assist in limiting the positioning, ensuring positioning stability and further improving the stability and accuracy of positioning.

[0024] The drive mechanism 4 includes a drive motor 41 and a reducer 42. The output shaft of the drive motor 41 is connected to the input shaft of the reducer 42. The output shaft of the reducer 42 is connected to multiple conveying rollers 3 through a transmission component 5. The drive motor 41 provides power, and the reducer 42 can convert the high-speed rotation of the drive motor 41 into the appropriate speed required by the conveying rollers 3, ensuring the stable conveying speed of the conveying rollers 3, meeting the speed requirements in the profile pressing process, and also improving the working reliability of the drive mechanism 4.

[0025] The transmission component 5 includes one of multiple pulleys, multiple sprockets, or multiple gears, and a ring transmission element 51 that cooperates with them; the ring transmission element 51 corresponding to the pulleys is a transmission belt, and belt transmission has the characteristics of buffering and absorbing vibration; the ring transmission element 51 corresponding to the sprockets is a chain, and chain transmission can ensure an accurate average transmission ratio; the ring transmission element 51 corresponding to the gears is a toothed belt, and gear transmission has high transmission accuracy; the appropriate transmission method can be selected according to the actual working environment and needs.

[0026] To achieve automatic response when profiles enter the conveying area, a sensor 21 for detecting the position of the profiles is installed on the upright plate 2. The sensor 21 can be a photoelectric sensor or a laser displacement sensor, installed near the feed end of the conveying roller 3, to detect whether the profile has entered the conveying area. When the front end of the profile reaches the detection range of the sensor 21, the sensor 21 will send a signal to the control system of the equipment. The control system will then start the drive mechanism 4 to make the conveying roller 3 start to rotate, thereby realizing the automatic conveying of the profiles, avoiding the timing deviation that may be caused by manual start-up, and improving the degree of automation.

[0027] The protective cover 6 is connected to the upright plate 2 via a rotating component 7. A handle 61 is provided on the side of the protective cover 6 away from the rotating component 7, and heat dissipation holes 62 are provided on the protective cover 6. The connection via the rotating component 7 allows the protective cover 6 to rotate around the rotating component 7, which facilitates the inspection and maintenance of the drive mechanism 4 and the transmission component 5. The handle 61 makes it easy for operators to open and close the protective cover 6. The heat dissipation holes 62 can dissipate the heat generated by the drive mechanism 4 during operation in a timely manner, preventing the equipment from being affected by overheating and affecting its service life and working performance.

[0028] like Figure 3 As shown, the outer surface of the conveying roller 3 is covered with a rubber layer 32. The rubber layer 32 has a certain elasticity and friction, which can increase the friction between the conveying roller 3 and the profile, prevent the profile from slipping during the conveying process, and ensure the stability of the conveying. At the same time, the rubber layer 32 can protect the surface of the profile and prevent the conveying roller 3 from scratching the surface of the profile.

[0029] The positioning structure of this utility model can be used in various types of profile pressing devices. This profile pressing device can achieve precise positioning and stable conveying of profiles. During the pressing process, the profiles are not prone to deviation or shaking, which improves the quality of profile pressing. At the same time, it reduces the operation steps of replacing and adjusting the limiting parts, saves time, and improves production efficiency.

[0030] 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.
