Technical Field

[0001] The utility model relates to the technical field of strip pinch roll technology, in particular to a strip slitting pinch roll device. Background Art

[0002] A strip is a long steel product with a certain width and thickness. It is usually produced by hot rolling or cold rolling processes. Hot-rolled strips have good plasticity and toughness and are suitable for some structural parts with low strength requirements; cold-rolled strips have higher surface quality and more accurate dimensional accuracy and are commonly used in fields such as automobile manufacturing and home appliance production where high requirements are placed on accuracy and surface quality. The strip has various materials, including ordinary carbon steel, alloy steel, etc. Its performance depends on the material composition and production process. In practical applications, strips are widely used in the manufacture of steel pipes, steel structures, hardware products, etc. For example, in the construction industry, they are used to make steel beams and steel columns; in the automotive industry, they are an important material for manufacturing body parts.

[0003] The prior art such as the utility model with the publication number CN214866122U discloses a pinch roll device for strip introduction and slitting shears. This patent uses a base, side plates, a top plate, and a flat plate; the side plates are arranged on both sides of the upper end of the base, the top plate is connected to the top of the side plates, and the flat plate is vertically connected to the side plates; an upper guiding component is arranged between the top plate and the flat plate, and an adjusting screw is connected between the top plate and the upper guiding component; a lower guiding component is arranged between the base and the flat plate; a left guiding component is connected to the left side position between the flat plate and the top plate, and a right guiding component is connected to the right side position between the flat plate and the top plate; this utility model avoids the problem that during the process of the loop roll forming a loop after the steel bites into the finishing mill, the steel shakes between the loop roll and the mill, resulting in jerks in the second flow rate of the steel in the deformation zone and uneven metal elongation in the deformation zone, causing bending; it can not only make the steel pass through the mill smoothly but also provide a stable clamping force to the steel throughout the rolling process, avoiding the shaking of the rolled piece and scratching the guide guard plate, reducing scratches, and solving the problem that the existing device structure cannot avoid the scratching between the steel and the guide guard liner, and at the same time, it is also very difficult to provide a stable clamping force to the steel and there is no way to limit the shaking of the steel when the loop roll rises and falls.

[0004] During the process of conveying the strip with the help of a feeding device, there is an existing feeding device such as the above. Its shaft rollers for guiding are directly installed at fixed installation positions. Since the enterprise produces a large number of strip specifications, when the shaft rollers are directly fixedly installed, the pinch roll device can only convey strips of a single specification, resulting in the applicability of the pinch roll device being limited by the shaft rollers, and then the applicable range of the pinch roll device is reduced. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the deficiencies in the prior art that when the shaft roller is directly fixedly installed, the pinch device can only convey strip steel of a single specification, resulting in the applicability of the pinch device being limited by the shaft roller, and then the applicable range of the pinch device is reduced. A strip steel slitting and pinch device is proposed.

[0006] To achieve the above purpose, the present utility model adopts the following technical solutions: A strip steel slitting and pinch device includes side baffles, a connecting frame, and an auxiliary component.

Sleeves are threadedly connected to the surfaces of the positive-thread shaft and the reverse-thread shaft. Mounting holes are formed on the surface of the restraint block, and the sleeves are fixedly connected to the inner walls of the mounting holes.

[0008] The auxiliary component further includes a linkage unit. The linkage unit includes a sprocket. The sprocket is threadedly connected to the surface of the reverse-thread shaft. A chain is meshed with the surface of the sprocket. A protective cover is fixedly connected to the side surface of the assembly frame. A threaded ring is fixedly connected to the inner wall of the protective cover. An adjusting frame is threadedly connected to the inner wall of the threaded ring. A clamping plate is rotatably connected to the surface of the adjusting frame. A damping pad is fixedly connected to the side surface of the clamping plate. The damping pad abuts against the side surface of the chain. Guide blocks are fixedly connected to both sides of the clamping plate, and the guide blocks are slidably connected to the inner wall of the protective cover.

[0009] Preferably, a knob is fixedly connected to the side surface of the positive-thread shaft. The knob is in contact with the side surface of the assembly frame. Through the cooperation of the positive-thread shaft and the coupling, the reverse-thread shaft can be driven to rotate synchronously while the staff rotates the knob.

[0010] Preferably, the number of the assembly frames is two. The two assembly frames are symmetrically arranged up and down with respect to the side baffle. Through the cooperation of the assembly frame and the coupling, the positions of the positive-thread shaft and the reverse-thread shaft can be restricted to ensure the stability of the positive-thread shaft and the reverse-thread shaft during the rotation state.

[0011] Preferably, the number of the binding blocks is two, and the two binding blocks are symmetrically arranged left and right with respect to the assembly frame. Grooves are formed on the surfaces of the binding blocks, and the vertical pinch rollers are rotatably connected to the inner walls of the grooves. The sleeve can be connected to the vertical pinch rollers through the binding blocks, so that when the sleeve moves, the vertical pinch rollers can be driven to displace.

[0012] Preferably, the number of the sprockets is two, and the two sprockets are symmetrically arranged up and down with respect to the chain. Through the cooperation of the sprockets and the chain, the reverse threaded shafts on the upper and lower sides can be connected, so that the two reverse threaded shafts can rotate synchronously.

[0013] Preferably, the protective cover is sleeved on the surfaces of the sprockets, and the protective cover is sleeved on the surface of the chain.

[0016] In the present utility model, by setting the auxiliary component, when processing, the distances between the vertical pinch rollers and the horizontal pinch rollers are adjusted so that the distances between the vertical pinch rollers and the horizontal pinch rollers are all adapted to the steel strip. Then, the steel strip is placed in the pinch zone formed by the vertical pinch rollers and the horizontal pinch rollers to guide the moving direction of the steel strip. When it is necessary to adjust the distance between the vertical pinch rollers, rotate the adjusting frame counterclockwise. The adjusting frame meshes with the threaded ring and pushes the clamping plate. Under the guidance of the guiding block, the clamping plate pulls the damping pad away from the chain. When the chain loses the clamping of the clamping plate and the damping pad, rotate the knob at the upper end of the side baffle clockwise. The knob rotates the positive threaded shaft, and the positive threaded shaft cooperates with the coupling to rotate the reverse threaded shaft. The reverse threaded shaft drives the chain under the cooperation of the sprocket. The chain cooperates with the sprocket below to drive the lower reverse threaded shaft. The lower reverse threaded shaft cooperates with the coupling to drive the other positive threaded shaft to rotate. When the positive threaded shafts and the reverse threaded shafts on the upper and lower sides rotate synchronously, the positive threaded shafts and the reverse threaded shafts respectively mesh with the sleeve. The sleeve moves the two vertical pinch rollers towards the center with the assistance of the binding blocks. During the movement of the two vertical pinch rollers, the distance between them is reduced, and then the adjustment of the distance between the vertical pinch rollers can be realized. By setting the auxiliary component, the roller distance of the pinch device can be adjusted according to the strip steel specification, thereby reducing the problem that the pinch device is difficult to adjust the distance, resulting in the limited application range, and further improving the application range of the pinch device.

[0027] Specifically, a knob 517 is fixedly connected to the side surface of the positive-thread shaft 514. The knob 517 is in contact with the side surface of the assembly frame 511. Through the cooperation of the positive-thread shaft 514 and the coupling 515, the reverse-thread shaft 516 can be driven to rotate synchronously while the staff rotates the knob 517.

[0028] Specifically, the number of the assembly frames 511 is two. The two assembly frames 511 are symmetrically arranged up and down with respect to the side baffle 1.

[0029] In this embodiment: Through the cooperation of the assembly frame 511 and the coupling 515, the positions of the positive-thread shaft 514 and the reverse-thread shaft 516 can be restricted to ensure the stability of the positive-thread shaft 514 and the reverse-thread shaft 516 during the rotation state.

[0030] Specifically, the number of the restraint blocks 512 is two. The two restraint blocks 512 are symmetrically arranged left and right with respect to the assembly frame 511.

[0036] Working principle: When processing, adjust the distance between the vertical pinch rollers 6 and the horizontal pinch rollers 4 so that the distances between the vertical pinch rollers 6 and the horizontal pinch rollers 4 are all adapted to the steel strip. Then place the steel strip into the pinch zone formed by the vertical pinch rollers 6 and the horizontal pinch rollers 4 to guide the moving direction of the steel strip. When it is necessary to adjust the distance between the vertical pinch rollers 6, rotate the adjusting frame 525 counterclockwise. The adjusting frame 525 meshes with the threaded ring 524 and pushes the clamping plate 526. Under the guidance of the guiding block 528, the clamping plate 526 pulls the damping pad 527 away from the chain 522. When the chain 522 loses the clamping of the clamping plate 526 and the damping pad 527, rotate the knob 517 at the upper end of the side baffle 1 clockwise.

When the right-threaded shafts 514 and the reverse-threaded shafts 516 on the upper and lower sides rotate synchronously, the right-threaded shafts 514 and the reverse-threaded shafts 516 respectively mesh with the sleeves 513. With the assistance of the restraint blocks 512, the sleeves 513 move the two vertical pinch rollers 6 towards the center. During the movement of the two vertical pinch rollers 6, the distance between them is reduced, and then the adjustment of the distance between the vertical pinch rollers 6 can be realized. By setting the auxiliary component 5, the roller distance of the pinch device can be adjusted according to the strip steel specification, thereby reducing the problem that the pinch device is difficult to adjust the distance, resulting in a limited application range, and further improving the application range of the pinch device.
