Description

Technical Field

[0001] This utility model relates to the field of crimping machine technology, and in particular to a side-pressing crimping machine. Background Technology

[0002] The eight-petal structure of a crimping machine is a common mold design, mainly used to achieve uniform pressure and shaping of the workpiece during the crimping process.

[0003] In the prior art, CN202447867U discloses a double-column slider pipe-locking machine, which has the following problems: the traditional eight-petal motion crimping of crimping machines is driven upward by the lower hydraulic cylinder. For crimping large flange workpieces, due to the large opening, the stroke of the crimping cylinder is very large, resulting in the center height of the eight petals being too high, which is inconvenient for operation.

[0004] Therefore, those skilled in the art urgently need to provide a side-pressing crimping machine that, by setting the cylinder on the side, can reduce the center height of the eight-petal structure and simplify the entire crimping process. Utility Model Content

[0005] The purpose of this invention is to provide a side-pressing crimping machine, which can reduce the center height of the eight-petal structure by setting the oil cylinder on the side, and the entire crimping process is simple to operate.

[0006] To achieve the above objectives, this utility model provides a side-pressing crimping machine, comprising a frame, a hydraulic cylinder, a movable plate, a slide rail, and a support. The hydraulic cylinder is installed on the right side of the frame, and an opening is provided in the middle of the frame. The top and bottom of the opening are fitted with the slide rail. The right end of the movable plate is fixedly connected to the movable end of the hydraulic cylinder. The top and bottom of the movable plate are respectively provided with sliders, which are slidably connected within the slide rail. An eight-petal structure is connected to the left end of the frame near the opening and the left end of the movable plate. The front end of the support is aligned with the front of the eight-petal structure. The support is provided with a height adjustment mechanism and a workpiece moving mechanism.

[0007] Preferably, the height adjustment mechanism includes a fixing block, a screw, and a washer. The side ends of the plurality of fixing blocks are respectively fixedly connected to the four corners of the bracket. A threaded through hole is provided in the middle of the fixing block. The screw is threadedly connected to the threaded through hole. A washer is fixedly connected to the bottom of the screw. The washer is in contact with the ground.

[0008] Preferably, the workpiece moving mechanism includes slide rail two and slide rail three. Two slide rail two are fixedly connected to the top of the bracket. The two slide rail two are arranged opposite to each other. Slider two are fixedly connected to both ends of the bottom of slide rail three. The slider two is slidably connected inside the slide rail two and matches the slide rail two.

[0009] Preferably, the workpiece moving mechanism further includes a workpiece placement frame, the bottom of which is provided with a slider three, which is slidably connected within the slide rail three, and the slider three matches the slide rail three.

[0010] Preferably, at least two slide rails three are provided between the two slide rails two.

[0011] Preferably, the top of the workpiece placement rack is provided with a wedge-shaped groove for placing the workpiece.

[0012] The advantages and positive effects of the side-pressure crimping machine described in this utility model are:

[0013] (1) By setting the cylinder on the side, this utility model significantly reduces the center height of the eight-petal structure. The side-press design makes the pressing process more stable and efficient, and the operation is simpler. It reduces the difficulty of operation and labor intensity, improves production efficiency, and solves the problem that when the traditional pressing machine presses large flange workpieces, the cylinder moves from bottom to top, which makes the cylinder stroke long and the center height of the eight petals too high, making it inconvenient to operate.

[0014] (2) The height of the workpiece can be finely adjusted by the height adjustment mechanism and the workpiece can be easily aligned with the center of the eight-petal structure by the workpiece moving mechanism. The operation is simple.

[0015] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1-2 As shown, a side-pressing crimping machine includes a frame 1, a hydraulic cylinder 2, a movable plate 3, a slide rail 4, and a bracket 5. The hydraulic cylinder 2 is installed on the right side of the frame 1, and an opening is provided in the middle of the frame 1. The slide rail 4 is installed at the top and bottom of the opening. The right end of the movable plate 3 is fixedly connected to the movable end of the hydraulic cylinder 2. The top and bottom of the movable plate 3 are respectively provided with sliders, which are slidably connected in the slide rail 4. An eight-petal structure is connected to the left end of the frame 1 near the opening and the left end of the movable plate 3. The front end of the bracket 5 is aligned with the front of the eight-petal structure. The bracket 5 is provided with a height adjustment mechanism and a workpiece moving mechanism.

[0024] Specifically, the opening and closing of the eight-petal structure is an existing structure, which can be found in patent CN202447867U. The main principle is that the eight-petal mold is pushed to slide in the frame track groove under the action of hydraulic power, and the spacing between the eight-petal mold can be reduced.

[0025] The height adjustment mechanism includes a fixing block 6, a screw 7, and a washer 8. The side ends of multiple fixing blocks 6 are respectively fixedly connected to the four corners of the bracket 5. A threaded through hole is provided in the middle of the fixing block 6. The screw 7 is threadedly connected to the threaded through hole. A washer 8 is fixedly connected to the bottom of the screw 7 and the washer 8 is in contact with the ground.

[0026] Specifically, rotating screw 7 adjusts the height of bracket 5, thereby adjusting the height of the workpiece.

[0027] The workpiece moving mechanism includes slide rail 2 9 and slide rail 3 10. The top of the bracket 5 is fixedly connected to two slide rails 2 9, which are arranged opposite to each other. The bottom ends of slide rail 3 10 are fixedly connected to sliders 2, which are slidably connected inside slide rails 2 9 and are matched with slide rails 2 9.

[0028] Specifically, the workpiece moves to the eight-lobed structure by moving the bottom of slide rail 3 10 along slide rail 2 9. Slide rail 2 9 and slide rail 3 10 are perpendicular to each other.

[0029] The workpiece moving mechanism also includes a workpiece placement rack 11. A slider 3 is provided at the bottom of the workpiece placement rack 11. The slider 3 is slidably connected in the slide rail 3 10, and the slider 3 matches the slide rail 3 10.

[0030] Specifically, by moving the workpiece placement rack 11 along the slide rail 3 10, the center of the workpiece can be easily aligned with the eight-petal structure.

[0031] At least two slide rails 10 are provided between the two slide rails 2 9, so that the workpiece can be placed on the two workpiece placement racks 11.

[0032] The top of the workpiece placement rack 11 is provided with a wedge-shaped groove for placing the workpiece, which makes it easy to lift the workpiece.

[0033] The usage process of this utility model is as follows:

[0034] First, the large flange workpiece to be crimped is placed on the workpiece placement rack 11 on the support 5 for support. The bottom of the slide rail 3 10 can move along the slide rail 2 9, so that the workpiece moves forward or backward. The workpiece placement rack 11 can move along the slide rail 3 10, so that the center of the workpiece is aligned with the center of the eight-petal structure.

[0035] Then, the hydraulic cylinder 2 is activated, and the movable end of the hydraulic cylinder 2 extends, thereby moving the moving plate 3 along the slide rail 4. The interaction between the eight petals realizes the pressing operation on the workpiece.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the 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 still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
