Description

Technical Field

[0001] This utility model relates to the field of slitting tool technology, and in particular to a high-efficiency and durable tungsten steel slitting tool. Background Technology

[0002] In the continuous production process of cable and wire sheathing materials such as wires and cables and optical fiber composite tapes, it is often necessary to slit wide rolls into multiple narrow strips. Traditional slitting equipment generally adopts a structure of rigid blade holder with carbide circular blades, which has the following significant drawbacks in practical applications: The cutting depth adjustment is inefficient. When multiple blades work together, the downward pressure needs to be changed manually by adjusting the blade holder bolts one by one, which is not only time-consuming but also makes it difficult to ensure the uniformity of the cutting depth of each blade. Fluctuations in packaging material tension can easily lead to problems such as burrs on the slitting edge and delamination of the cross-section, which directly affect the insulation performance and appearance quality of the product.

[0003] The tool position is not flexible enough. Most existing tool arms adopt an integral long shaft structure, which has poor adjustment flexibility.

[0004] To address the aforementioned pain points, there is an urgent need to develop a slitting system with multi-blade synchronous precision adjustment and independent blade position stepless positioning, in order to meet the stringent requirements of modern cable manufacturing for slitting quality, production cycle time, and equipment stability. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a high-efficiency and durable tungsten carbide slitting knife to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of the present invention provides a high-efficiency and durable tungsten steel slitting knife, including an electric cylinder, a tailstock, and a connector. The tailstock is fixedly connected to the root of the electric cylinder, the electric cylinder is rotatable, and the connector is fixedly connected to the end of the output end of the electric cylinder. A rotating arm is movably connected to the inner side of the joint, and a main shaft is fixedly connected to the bottom end of the rotating arm; The main shaft is rotatable, and a fixed seat is provided below the electric cylinder. The fixed seat is bent, and a bearing is fixedly connected to the end of the fixed seat. A main shaft is installed in the bearing, and several collars are fixedly connected to the outer surface of the main shaft. The collars are fastened in position with fasteners. One side of the collar is fixedly connected to a main arm, and one side of the main arm is movably connected to a secondary arm. The main arm and the secondary arm are provided with through holes, and a connecting piece is tightly fastened in the through holes. A tungsten steel slitting blade is detachably connected to the inner side of the bottom end of the secondary arm.

[0008] Preferably, in any of the above embodiments, the electric cylinder is perpendicular to the spindle, and the joint is U-shaped.

[0009] The above technical solution utilizes a device specifically designed for cutting cable sheathing materials. Specifically, it cuts a single sheet of cable sheathing material into multiple strips, with tungsten carbide slitting blades performing the cutting. The cable sheathing material is tensioned and passed under the main shaft by the unwinding and rewinding action of the drive device. Multiple tungsten carbide slitting blades work together to cut the entire sheathing material into multiple strips.

[0010] Preferably, in any of the above embodiments, the rotating arm is perpendicular to the main shaft, and the fixed seat has chemical bolt holes.

[0011] The core of this device, using the above technical solution, is that the cutting thickness of the multiple slitting blades can be adjusted synchronously. Specifically, the electric cylinder is movable, with a tailstock at the rear and a connector at the output end. When the output end of the electric cylinder pushes out, the connector pushes the rotating arm downward, causing the main shaft to rotate and drive the main arm, auxiliary arm, and tungsten steel slitting blade to press down. Conversely, the tungsten steel slitting blade is raised, thus achieving precise synchronous adjustment of the cutting depth of the multiple blades. The main arm and auxiliary arm are segmented and movably connected. Each blade can be independently adjusted steplessly along the blade arm direction. After adjustment, multiple connectors are used to tighten them, which can improve the cutting flexibility and adapt to the edge characteristics of different materials. It can compensate for manufacturing errors (such as slight deviations in the blade arm installation position).

[0012] Preferably, in any of the above schemes, the bending angle of the fixing seat is ninety degrees, and there are multiple collars arranged linearly on the outer surface of the spindle.

[0013] The above technical solution comprises the following components: the base of the electric cylinder is fixed to the equipment frame via a tailstock, and a U-shaped connector is assembled at the end of the electric cylinder output shaft. The upper end of the rotating arm is movably connected to the inner side of the connector via a bearing, and the bottom end of the rotating arm is vertically fixed to the main shaft.

[0014] A bent mounting base is installed below the spindle, with one end fixed to the base by chemical bolts and the other end fitted with a bearing. The spindle passes through the bearing to achieve rotational freedom. Multiple collars are linearly arrayed on the spindle surface, and the collars are radially locked by hexagonal socket head cap screws.

[0015] The main boom is welded to the sides of each collar, and the main boom has longitudinal through holes. The upper section of the auxiliary boom is inserted into the through holes of the main boom and secured by a connector consisting of a washer nut and bolts. The tungsten carbide slitting blade is fixed with a lock nut after installation.

[0016] Preferably, in any of the above solutions, the fastener is a hexagon socket screw, the fastener is inserted into a collar, and the fastener is threaded to the corresponding part of the spindle.

[0017] Preferably, in any of the above solutions, the total length of the main arm and the auxiliary arm is adjustable, and the connecting parts are specifically bolts and washer nuts.

[0018] Preferably, the tungsten carbide slitting blade is inserted into the end of the auxiliary arm and then tightened with a nut.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This high-efficiency and durable tungsten carbide slitting knife features multiple slitting knives that can synchronously adjust the cutting thickness. Specifically, the electric cylinder is movable, with a tailstock at the rear and a connector at the output end. When the output end of the electric cylinder pushes out, the connector pushes the rotating arm downward, causing the main shaft to rotate and drive the main arm, auxiliary arm, and tungsten carbide slitting knife downward. Conversely, the tungsten carbide slitting knife rises, achieving precise synchronous adjustment of the cutting depth of multiple knives. The main arm and auxiliary arm are segmented and movably connected. Each blade can be independently adjusted steplessly along the blade arm direction. After adjustment, multiple connectors are used to tighten them, which can improve the cutting flexibility and adapt to the edge characteristics of different materials. It can compensate for manufacturing errors (such as slight deviations in the blade arm installation position).

[0025] like Figure 1-4 As shown, this high-efficiency and durable tungsten carbide slitting knife includes an electric cylinder 1, a tailstock 2, and a connector 3. The tailstock 2 is fixedly connected to the root of the electric cylinder 1. The electric cylinder 1 is rotatable. The connector 3 is fixedly connected to the end of the output end of the electric cylinder 1. A rotating arm 4 is movably connected to the inner side of the connector 3, and a main shaft 5 is fixedly connected to the bottom end of the rotating arm 4; The main shaft 5 is rotatable, and a fixed seat 6 is provided below the electric cylinder 1. The fixed seat 6 is bent, and a bearing 7 is fixedly connected to the end of the fixed seat 6. The bearing 7 houses the spindle 5, and several collars 8 are fixedly connected to the outer surface of the spindle 5. The collars 8 are fastened in position by fasteners 9. One side of the collar 8 is fixedly connected to the main arm 10, and the other side of the main arm 10 is movably connected to the auxiliary arm 11. The main arm 10 and the auxiliary arm 11 are provided with through holes 12, and a connecting piece 13 is tightly fastened in the through hole 12. A tungsten steel slitting blade 14 is detachably connected to the inner side of the bottom end of the auxiliary arm 11.

[0026] Example 1: The electric cylinder 1 is perpendicular to the main shaft 5, and the connector 3 is U-shaped. The rotating arm 4 is perpendicular to the main shaft 5, and the fixed seat 6 has holes for chemical bolts. The bending angle of the fixed seat 6 is 90 degrees, and multiple collars 8 are linearly arrayed on the outer surface of the main shaft 5. The fastener 9 is specifically a hex socket head cap screw, which is inserted into the collar 8 and threaded to the corresponding part of the main shaft 5. The total length of the main arm 10 and the auxiliary arm 11 is adjustable, and the connecting part 13 is specifically a bolt and a washer nut. The shaft of the tungsten carbide slitting blade 14 is inserted into the end of the auxiliary arm 11 and then tightened with a nut.

[0027] Example 2: This device is specifically designed for cutting cable sheathing materials, specifically cutting a whole sheet of cable sheathing material into multiple strips. The cutting mechanism is a tungsten carbide slitting blade 14. The cable sheathing material is tensioned and passes under the main shaft 5 under the action of the unwinding and rewinding action of the drive device. Multiple tungsten carbide slitting blades 14 work together to cut the whole sheet of sheathing material into multiple strips. Device composition: The base of the electric cylinder 1 is fixed to the equipment frame via the tailstock 2. A U-shaped connector 3 is assembled at the end of the output shaft of the electric cylinder 1. The inner side of the connector 3 is movably connected to the upper end of the rotating arm 4 via a bearing. The bottom end of the rotating arm 4 is vertically fixed to the main shaft 5.

[0028] A 90-degree bent mounting base 6 is installed below the spindle 5, one end of which is fixed to the base by a chemical bolt, and the other end is fitted with a bearing 7. The spindle 5 passes through the bearing 7 to achieve rotational freedom. Multiple collars 8 are linearly arrayed on the surface of the spindle 5, and the collars 8 are radially locked by hexagonal socket screws 9.

[0029] Each collar 8 is side-welded to the main arm 10, and the main arm 10 has a longitudinal through hole 12. The upper section of the auxiliary arm 11 is inserted into the through hole 12 of the main arm 10 and fastened by a connector 13 consisting of a washer nut and bolts. The tungsten carbide slitting blade 14 is fixed by a lock nut after installation.

[0030] The working principle of this utility model is as follows: Cutting depth synchronous adjustment: When the output end of the electric cylinder 1 is pushed out, the U-shaped connector 3 is pushed down, which drives the rotating arm 4 to rotate clockwise around the center of the main shaft 5. The main shaft 5 rotates synchronously in the bearing 7. The main arm 10, which is fixed to the collar 8, swings down. All the auxiliary arms 11 and the tungsten carbide slitting blade 14 press down synchronously to increase the cutting depth. When the electric cylinder 1 retracts, the rotating arm 4 is pulled in the opposite direction, the main shaft 5 rotates counterclockwise, and the entire blade assembly is raised to reduce the cutting depth.

[0031] A single electric cylinder can precisely control the cutting depth of all blades, ensuring consistent cuts across the entire material.

[0032] Independent adjustment method: Loosen the connector 13 on the target tool position, and slide the auxiliary arm 11 laterally in the through hole 12 of the main arm 10. The lateral offset of the blade 14 is calibrated by the scale on the surface of the auxiliary arm 11, and the connector 13 is re-locked. This design allows for: compensation for cumulative assembly errors of the blade arm; and rapid adjustment of the single blade position to cope with changes in the edge properties of the material.

[0033] Compared with the prior art, the present invention has the following advantages: This high-efficiency and durable tungsten steel slitting knife allows for simultaneous adjustment of cutting thickness across multiple slitting blades. Specifically, the electric cylinder 1 is movable, with a tailstock 2 at its tail end and a connector 3 at the output end of the electric cylinder 1. When the output end of the electric cylinder 1 pushes out, the connector 3 pushes down the rotating arm 4, causing the main shaft 5 to rotate and drive the main arm 10, auxiliary arm 11, and tungsten steel slitting blade 14 to press down. Conversely, the tungsten steel slitting blade 14 is raised, achieving precise and synchronous adjustment of the cutting depth across multiple blades. The main arm 10 and the auxiliary arm 11 are segmented and movably connected. Each blade can be independently adjusted steplessly along the blade arm direction. After adjustment, they are tightened with multiple connectors 13, which can improve the cutting flexibility and adapt to the edge characteristics of different materials. It can also compensate for manufacturing errors (such as slight deviations in the blade arm installation position).
