Description

Technical Field

[0001] The utility model provides a steel strip shearing machine with adjustable spacing, belonging to the technical field of steel strip production and processing. Background Technique

[0002] A steel strip is a narrow and long steel plate produced by various rolling mills to meet the needs of different industrial sectors for industrial production of various metal or mechanical products. The steel strip is also called strip steel, with a width within 1300 mm and a length slightly different according to the size of each roll. According to the quality of the steel, it is divided into high-quality and ordinary strip steel; according to the rolling method, it is divided into hot-rolled and cold-rolled, which are called hot-rolled strip steel and cold-rolled strip steel respectively. After the steel strip is processed and produced, since the produced steel strip is usually a large roll as a whole, a shearing machine is usually needed to cut the whole steel strip into multiple steel strips.

[0003] Existing shearing machines can basically meet the shearing needs of steel strips, but there are still certain defects: multiple circular shearing knives are usually directly fixed on the shearing rolls of existing shearing machines, and the width between multiple circular shearing knives is often relatively fixed and often cannot be adjusted according to the use needs. Therefore, only steel strips of a certain specification can be sheared. When it is necessary to shear steel strips of other specification widths according to the use needs, the whole shearing roll usually needs to be disassembled and then a shearing roll of the corresponding specification is installed, and the operation is rather cumbersome. Based on this, the utility model provides a steel strip shearing machine with adjustable spacing. Content of the Utility Model

[0004] The technical problem solved by the utility model is that when shearing steel strips of other specifications, the whole shearing roll usually needs to be disassembled and then a shearing roll of the corresponding specification is installed, and the operation is rather cumbersome, and the spacing between the circular shearing knives on the shearing roll cannot be adjusted according to the use needs.

[0005] To solve the technical problem, the technical solution provided by the utility model is: a steel strip shearing machine with adjustable spacing, including a base, two symmetrically arranged support plates are provided on both sides of the top of the base, a pair of shearing rolls are rotatably connected between the support plates, multiple circular shearing knives and locking discs symmetrically arranged on both sides of the circular shearing knives are slidably connected to the shearing rolls, a chute matching with both the circular shearing knives and the locking discs is provided on the circumference of the shearing rolls, a groove is provided on the outer wall of the locking disc above the chute, and a locking component is provided in the groove. The locking component includes a hollow block, a slide plate is slidably connected in the hollow block, and a locking rod inserted into the chute is provided at the bottom of the slide plate.

[0006] Further, the locking rod passes through the bottom of the hollow block and the locking disc, a pull rod passing through the top of the hollow block is provided at the top of the slide plate, a handle is provided at the end of the pull rod, and a return spring is sleeved on the pull rod between the inner top wall of the hollow block and the top wall of the slide plate.

[0007] Further, a plurality of locking holes matching the locking rods are equidistantly arranged in the sliding groove.

[0008] Further, a driving motor for driving the shearing roller to rotate is arranged on the outer side wall of one of the supporting plates.

[0009] Further, the sliding grooves are triangularly distributed on the shearing roller, and sliding rails matching the sliding grooves are arranged on the inner side walls of the disc shearing knife and the locking disc.

[0010] Further, limiting rails matching the side walls of the sliding plates are symmetrically arranged on the inner side wall of the hollow block.

[0011] Advantages of the utility model:

[0012] Under the combined action of the locking disc and the locking assembly, etc., the positions of the disc shearing knife and the locking disc on the shearing roller can be adjusted, so that the position of the disc shearing knife is locked between the locking discs.

[0019] The following further describes the utility model with reference to the drawings.

[0020] According to the attached Figure 1 , 2, as shown in FIGS. 3: The utility model provides a steel belt shearing machine with adjustable spacing, which includes a base 1. On both sides of the top of the base 1, support plates 2 are symmetrically arranged. A pair of shearing rollers 3 are rotatably connected between the support plates 2. A plurality of disc shearing knives 4 and locking discs 5 symmetrically arranged on both sides of the disc shearing knives 4 are slidably connected to the shearing rollers 3. A chute 6 that matches both the disc shearing knives 4 and the locking discs 5 is provided circumferentially on the shearing rollers 3. The chute 6 is distributed in a triangular shape on the shearing rollers 3. Slide rails 16 that match the chute 6 are provided on the inner side walls of the disc shearing knives 4 and the locking discs 5, which play a role in limiting the disc shearing knives 4 and the locking discs 5. The locking discs 5 can lock the positions of the disc shearing knives 4. A driving motor 15 for driving the shearing rollers 3 to rotate is provided on the outer side wall of one of the support plates 2. When shearing the steel belt, the steel belt to be sheared passes through between the pair of shearing rollers 3. By starting the driving motor 15 to drive the shearing rollers 3 to rotate, and then driving the disc shearing knives 4 to rotate, the steel belt passing through between the shearing rollers 3 is sheared.

[0021] According to the attached Figure 3 , 4 , as shown in FIGS. 5: A groove 7 is provided on the outer wall of the locking disc 5 above the chute 6. A locking component 8 is provided in the groove 7. The locking component 8 includes a hollow block 9. A slide plate 10 is slidably connected in the hollow block 9. Limiting rails 17 that match the side walls of the slide plate 10 are symmetrically provided on the inner side walls of the hollow block 9, which play a role in limiting the slide plate 10. A locking rod 11 that passes through the bottom of the hollow block 9, the locking disc 5 and inserts into the chute 6 is provided at the bottom of the slide plate 10. A plurality of locking holes 14 that match the locking rod 11 are equidistantly provided in the chute 6. A pull rod 12 that passes through the top of the hollow block 9 is provided at the top of the slide plate 10. A grip is provided at the end of the pull rod 12. A return spring 13 is sleeved on the pull rod 12 between the inner top wall of the hollow block 9 and the top wall of the slide plate 10. By matching the locking rod 11 with the locking holes 14 at appropriate positions, the positions of the disc shearing knives 4 and the locking discs 5 on the shearing rollers 3 can be adjusted. The positions of the disc shearing knives 4 are locked between the locking discs 5. Without disassembling the entire shearing roller 3 and then installing the shearing roller 3 of the corresponding specification, the spacing between the disc shearing knives 4 can be adjusted according to needs, and then steel belts of other specifications can be sheared. The operation is relatively simple.

[0022] The principle of the utility model

[0023] During use, when shearing the steel belt, the steel belt to be sheared passes through between the pair of shearing rollers 3. By starting the driving motor 15 to drive the shearing rollers 3 to rotate, and then driving the disc shearing knives 4 to rotate, the steel belt passing through between the shearing rollers 3 is sheared;

[0024] When it is necessary to adjust the spacing between the disc shearing knives 4, pull outwards by holding the handle, thereby driving the pull rod 12, the sliding plate 10, and the locking rod 11 to move outwards until the locking rod 11 moves out of the locking hole 14. At this time, the return spring 13 is in a compressed state. Then pull the locking disc 5 outwards so that the locking rod 11 and the locking hole 14 are no longer in communication. After that, release the handle. Since the locking rod 11 interferes with the locking hole 14, the return spring 13 will not rebound and reset. Then slide the locking disc 5 on the shearing roller 3 and move it to a suitable position as needed until the locking rod 11 and the locking hole 14 are in communication. The compressed return spring 13 rebounds and resets, driving the pull rod 12, the sliding plate 10, and the locking rod 11 to move inwards until the locking rod 11 is inserted into the locking hole 14, and the position of the locking disc 5 can be locked. Then move the corresponding disc shearing knife 4 and the locking disc 5 on the other side of the disc shearing knife 4 to suitable positions, and thus the positions of the disc shearing knife 4 and the locking disc 5 on the shearing roller 3 can be adjusted, so that the position of the disc shearing knife 4 is locked between the locking discs 5. There is no need to disassemble the entire shearing roller 3 and then install the shearing roller 3 of the corresponding specification. That is, the spacing between the disc shearing knives 4 can be adjusted as needed, and thus steel strips of other specifications can be sheared, and the operation is relatively simple.

[0025] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the creation of the present utility model, creatively design a structural manner and an embodiment similar to this technical solution, they shall fall within the protection scope of the present utility model.
