Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a stretching device of a tension leveling machine. Background Art

[0002] A tension leveling machine is a mechanical device used for metal material processing, mainly used for stretching, straightening and flattening metal coils to meet specific size, thickness and shape requirements. It usually consists of a series of rollers, a tensioning device, a control system and other components. Through the rotation of the rollers and the action of the tensioning device, the metal coil is stretched, straightened and flattened when passing through the tension leveling machine. The tension leveling machine is widely used in the metal processing and manufacturing industries for producing various metal sheets, coils and other products. In the current technology, basically rolls are used to achieve this function. Then, due to design reasons, the distance between the rolls is basically in a relatively fixed manner. Although this method can meet the function of stretching and rolling the strip, it cannot achieve the purpose of a single machine being applicable to multiple strip models.

[0003] Therefore, we propose a stretching device of a tension leveling machine. Summary of the Utility Model

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a stretching device of a tension leveling machine.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a stretching device of a tension leveling machine, including an installation bracket. An upper stretching roller and a lower stretching roller are arranged in the inner cavity of the installation bracket. First chutes and second chutes are respectively opened on two side wall surfaces of the installation bracket. A driving motor is fixedly connected to the bottom of the inner cavity of the second chute. Screw rods are fixedly connected to the output shaft ends of the driving motor. Sliding blocks are slidably connected to both screw rods. Bearing plates are fixedly connected to the ends of the two sliding blocks away from each other. Push rods are fixedly connected to the side wall surfaces of the bearing plates close to the first chute. Installation blocks are fixedly connected to the tops of the two push rods.

[0006] Preferably, limit blocks are fixedly connected to the ends of the bearing plates away from each other. First limit grooves are opened on two side wall surfaces of the second chute. Second limit grooves are opened on the side wall surfaces of the two first limit grooves away from each other.

[0007] Preferably, the second limit grooves cooperate with the limit blocks, and the bearing plates cooperate with the first limit grooves.

[0008] Preferably, the push rods penetrate through the top wall surface of the inner cavity of the second chute, and both ends of the upper stretching roller are connected to the installation blocks.

[0009] Preferably, the first sliding groove is formed on the two side wall surfaces of the mounting bracket at positions corresponding to both ends of the upper stretching roller, and the second sliding groove is formed on the side wall surface of the mounting bracket and is located below the first sliding groove.

[0010] Preferably, the number of lower stretching rollers is two, and the upper stretching roller is arranged obliquely above the two lower stretching rollers.

[0011] Beneficial effects

[0012] The utility model provides a stretching device of a tension leveling machine. It has the following beneficial effects:

[0013] (1) For the stretching device of the tension leveling machine, through the combination of the driving motor driving the lead screw and the sliding block, the mounting block on the pushing rod can move up and down, so as to adjust the distance between the upper stretching roller and the two lower stretching rollers. This design with adjustable distance enables this machine to adapt to various strip types without the need to replace or adjust the fixed distance of the rollers, and can more flexibly adapt to different production requirements, improve production efficiency and product quality, reduce production costs, and bring considerable benefits to production enterprises.

[0014] (2) For the stretching device of the tension leveling machine, through the cooperation of the bearing plate and the first limiting groove, and the limiting block is limited in the inner cavity of the second limiting groove, the sliding block is more stable and controllable during displacement. This design effectively prevents the instability of the sliding block during displacement and ensures the accuracy and stability of the stretching process. Description of the drawings

[0023] Embodiment: A stretching device of a tension leveling machine, as Figures 1-3 shown, includes an installation bracket 1. The inner cavity of the installation bracket 1 is movably connected with an upper stretching roller 2 and two lower stretching rollers 3 through bearings. The upper stretching roller 2 is arranged obliquely above the two lower stretching rollers 3. First chutes 4 are provided at positions corresponding to both ends of the upper stretching roller 2 on the two side wall surfaces of the installation bracket 1. Second chutes 5 are provided on the installation bracket 1 and below the first chutes 4. Driving motors 501 are fixedly connected to the central positions of the bottoms of the inner cavities of the two second chutes 5. The output shaft ends of the two driving motors 501 are fixedly connected with lead screws 502. The other ends of the lead screws 502 are rotatably connected to the top positions of the inner cavities of the second chutes 5. Sliding blocks 503 are slidably connected to the two lead screws 502. Bearing plates 6 are fixedly connected to the ends of the two sliding blocks 503 away from each other. Pushing rods 601 are fixedly connected to the side wall surfaces of the bearing plates 6 close to the first chutes 4. The pushing rods 601 penetrate through the top wall surfaces of the inner cavities of the second chutes 5. Installation blocks 602 are fixedly connected to the tops of the two pushing rods 601. Both ends of the upper stretching roller 2 are connected to the installation blocks 602.

[0024] Limiting blocks 603 are fixedly connected to the ends of the bearing plates 6 away from each other. First limiting grooves 604 are provided on the two side wall surfaces of the second chutes 5.

The second limiting grooves 605 cooperate with the limiting blocks 603, and the bearing plates 6 cooperate with the first limiting grooves 604.

[0025] Working principle of the utility model:

[0026] During use, starting the drive motor 501 drives the sliding block 503 on the lead screw 502 to displace, thereby driving the mounting block 602 on the push rod 601 to move up and down, and then the distance between the upper stretching roller 2 and the two lower stretching rollers 3 can be adjusted. Through the cooperation of the bearing plate 6 and the first limiting groove 604, and the limiting block 603 is limited in the inner cavity of the second limiting groove 605, making the sliding block 503 move more smoothly during displacement.

[0027] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.

[0028] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of this application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.
