Description

Technical Field

[0001] This utility model relates to the field of production fixture technology, and in particular to a profile extrusion tooling. Background Technology

[0002] In the production of distribution boxes and cabinets, structural profiles such as square steel are required as the main frame of the distribution boxes and cabinets. However, as the types of distribution boxes and cabinets differ, the required frame load-bearing capacity design also varies. Standard square steel profiles cannot meet the production needs for maximum efficiency in terms of size and load-bearing capacity. If non-standard profiles are purchased, it is difficult to balance the required quantity and cost.

[0003] In the production of electrical distribution boxes and cabinets, their doors and panels are also obtained through sheet metal punching, bending, and welding. To reduce production costs, non-standard profiles are obtained through sheet metal punching, bending, and welding. However, due to the actual production process, the sides of the profiles obtained through this punching process cannot be guaranteed to be completely closed. For example… Figure 3 For the rectangular cross-section profile shown, the openings need to be extruded and pressed together before subsequent welding can be performed. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a profile extrusion fixture, comprising a frame. Fixed rollers and sliding rollers are respectively arranged at the lower and upper parts of the frame. The fixed rollers and sliding rollers have identical structures, each including a fixed shaft. Two sliding sleeves are slidably mounted on the fixed shaft, and bearings are fixedly connected to the sliding sleeves. A shaft roller is fixedly connected to the outer ring of the bearing, and a limiting protrusion is fixedly connected to the middle of the shaft roller. In total, four shaft rollers are provided. The profile passes through the shaft rollers, and the limiting protrusion limits its movement, thereby controlling the deformation of the profile and facilitating subsequent welding and other operations.

[0005] The frame has grooves on both upper sides, and the two ends of the sliding roller are slidably engaged in the grooves. That is, the sliding roller can be raised and lowered, and with the coaxial adjustable spacing of the roller, it can be adapted to profiles of different sizes.

[0006] Preferably, the sidewall of the fixed shaft has an axially oriented cross-section, which is perpendicular to a certain radial direction of the fixed shaft. The inner bore profile of the sliding sleeve matches the cross-sectional profile of the fixed shaft. A second fixing bolt is threaded onto the sidewall of the sliding sleeve, with one end of the second fixing bolt abutting against the cross-section. By tightening the second fixing bolt, the sliding sleeve is fixed, thus limiting the movement of the shaft roller.

[0007] Preferably, a connector is provided at the end of the sliding roller, and a guide rod is provided on the side wall of the frame, with the guide rod sliding through the connector. The connector and guide rod enable stable up-and-down sliding of the sliding roller.

[0008] Preferably, a connecting plate is provided at the upper end of the frame, and a second connecting lug is provided at the lower part of the frame. One end of the guide rod is fitted onto the second connecting lug, and the other end passes through the connecting plate. Both ends of the guide rod are threaded with nuts. That is, the guide rod not only serves a guiding function but also fixes the connecting plate to the upper end of the frame.

[0009] Preferably, a T-shaped limiting block is slidably disposed inside the slide groove, and a first fixing bolt is inserted through the middle of the connecting member, with the first fixing bolt and the limiting block being threadedly connected. The protruding part of the limiting block is slidably fitted in the slide groove to prevent the limiting block from rotating with the first fixing bolt. When it is necessary to adjust the height of the sliding roller, the first fixing bolt is loosened, that is, after the clamping effect of the limiting block and the connecting member frame is eliminated, the sliding roller can be raised and lowered. Tightening the first fixing bolt fixes the sliding roller.

[0010] Preferably, the end of the fixed shaft is threaded with a hexagon socket head cap screw, and the hexagon socket head cap screw has three steps, with a smooth cylindrical surface in the middle section, and fits into a slot provided on the frame. Specifically, the middle section of the hexagon socket head cap screw on the sliding roller is slidably fitted in a groove.

[0011] Preferably, the frame has first connecting ears at each of its four lower corners, and the connecting plate has through holes on both sides of its edges. The first connecting ears and through holes facilitate the fixing of the tooling.

[0012] The beneficial effects of this utility model are as follows: 1. The structure of the shaft roller and the limiting convex ring is used to squeeze and constrain the profile that passes through, so that the opening of the profile is closed, which is conducive to welding at the opening.

[0013] 2. The spacing between the coaxial rollers can be adjusted, and the sliding rollers can move up and down. The area enclosed by the four rollers can be adjusted to meet the production needs of various profiles. Attached Figure Description

It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0017] like Figures 1 to 3 As shown, a profile extrusion fixture includes a frame 1, which is a U-shaped sheet metal part formed by multiple punching and bending processes. Fixed rollers and sliding rollers are respectively installed at the lower and upper parts of the frame 1. The fixed rollers and sliding rollers have identical structures, both including a fixed shaft 2. The length of the fixed shaft 2 is exactly the width of the inner side of the frame 1. Two sliding sleeves 13 are slidably mounted on the fixed shaft 2, meaning the distance between the two sliding sleeves 13 is adjustable. Bearings 14 are fixedly connected to the sliding sleeves 13. A shaft roller 15 is fixedly connected to the outer ring of the bearing 14. All components directly connected to the bearing 14 are fixed using an interference fit. A limiting ring 16 is fixedly connected to the middle of the shaft roller 15. There are a total of four shaft rollers 15, and the limiting ring 16 is used to abut and clamp the profile passing through it. Figure 3 As shown, the sheet metal part is similar to a square steel profile structure after multiple stamping and bending. However, its edge is open and needs to be fixed by welding. During welding, the opening needs to be closed to meet the welding requirements. In this utility model, the opening is closed by the extrusion constraint of four rollers 15 and the limiting protrusion ring 16, so that the welding process can be carried out.

[0018] The upper sides of both sides of the frame 1 are provided with sliding grooves 6, and the two ends of the sliding roller are slidably engaged in the sliding grooves 6, that is, the sliding roller slides up and down in the sliding grooves 6.

[0019] The side wall of the fixed shaft 2 has a cross-section axially provided, and the cross-section is perpendicular to a certain radial direction of the fixed shaft 2. That is, the cross-sectional profile of the fixed shaft 2 is a closed shape composed of a circular arc and a straight line. The inner hole profile of the sliding sleeve 13 is adapted to the cross-sectional profile of the fixed shaft 2. This arrangement is to prevent the sliding sleeve 13 from rotating on the fixed shaft 2. The side wall of the sliding sleeve 13 is threaded with a second fixing bolt 12. One end of the second fixing bolt 12 abuts against the cross-section. After loosening the second fixing bolt 12, the sliding sleeve 13 is unrestricted and its position on the fixed shaft 2 can be adjusted.

[0020] The end of the sliding roller is provided with a connector 7. The front outline of the connector 7 in the figure is L-shaped. The side wall of the frame 1 is provided with a guide rod 5, and the guide rod 5 slides through the connector 7. The connection of the connector 7 and the guide rod 5 ensures the stability of the sliding roller sliding up and down.

[0021] A connecting plate 8 is provided at the upper end of the frame 1. The connecting plate 8 is a single plate that forms a closed structure with the frame 1, thereby improving the structural strength of the tooling body. A second connecting lug 4 is provided at the lower part of the frame 1. One end of the guide rod 5 is fitted onto the second connecting lug 4, and the other end passes through the connecting plate 8. Both ends of the guide rod 5 are threaded with nuts, that is, the end of the guide rod 5 is threaded, and the connecting plate 8 is fixedly connected to the frame 1.

[0022] The slide groove 6 is equipped with a T-shaped limiting block 11. A part of the limiting block 11 is slidably engaged in the slide groove 6. This arrangement ensures that the limiting block 11 can only slide up and down. The connecting piece 7 is provided with a first fixing bolt 9 through the middle, and the first fixing bolt 9 is threadedly connected to the limiting block 11. When the first fixing bolt 9 is tightened, the limiting block 11 and the connecting piece 7 clamp the frame 1 to fix the sliding roller. When the sliding roller is raised or lowered, the first fixing bolt 9 can be loosened.

[0023] The end of the fixed shaft 2 is threaded with an internal hex bolt 10, which has three steps. The middle section is a smooth cylindrical surface that fits into a slot on the frame 1. The front section is a threaded end that is threaded to the fixed shaft 2, and the rear section is an internal hex bolt. In addition, the connector 7 is inserted on the middle section, while on the fixed roller, the connector is replaced by an annular washer.

[0024] The lower four corners of the frame 1 are provided with first connecting ears 3. The first connecting ears 3 are provided with not only vertical holes, but also horizontal through holes. Both sides of the connecting plate 8 are provided with through holes. With the help of the through holes, the fixture can be flexibly fixed.
