Description

Technical Field

[0001] The utility model belongs to the technical field of robots, in particular to a flexible steel strip processing device. Background Art

[0002] Stainless steel strip, a high-performance metal material, is widely used across various industries due to its unique material properties. These include construction, automotive manufacturing, food processing, medical equipment, petrochemicals, and home appliance manufacturing, among others. Its core advantage lies in its excellent corrosion resistance, thanks to the addition of chromium (Cr) to the steel. When the chromium content reaches a certain level, a dense oxide film (passivation film) forms on the steel surface, effectively shielding it from corrosion by oxygen, water, and most chemicals. Furthermore, stainless steel strip exhibits excellent strength, toughness, processability, and weldability, maintaining stable physical and chemical properties in a variety of environments.

[0003] Stainless steel strips have a high degree of hardness, allowing them to maintain their shape and performance in a variety of environments. Typically containing high levels of carbon and chromium, these strips are hard enough to withstand significant pressure and tension. Their hardness ensures structural stability and durability, while their formability allows them to meet a variety of complex design requirements.

[0004] For existing steel belt processing methods, please refer to the existing patent CN110878813B, "A Steel Belt Pre-Tightening Method". In this patent, the steel belt is wound on a steel belt pulley, and the two ends of the steel belt are respectively wound in the belt grooves on the two steel belt pulleys, and the ends of the steel belt are positioned by fastening screws. Since the steel belt itself has a certain thickness, and in actual practice it is impossible to work with only one steel belt, multiple steel belts are usually stacked for practical use; the thickness of the belt groove and the height of the fastening screws are certain; and the requirements for steel belts on different robots are different. Therefore, once the steel belt thickness is large and the number of steel belts is large, some steel belts will exceed the height of the belt groove, and thus the processing accuracy cannot be guaranteed; therefore, this steel belt processing method has a narrow scope of application.

[0005] In order to solve the above problems, designing a flexible steel strip processing device is an important technical problem that those skilled in the art need to solve. Utility Model Content

[0006] The purpose of the present invention is to solve the above problems existing in the prior art and to provide a flexible steel strip processing device.

[0007] The purpose of this utility model is achieved through the following technical solutions:

[0008] A flexible steel strip processing device comprises a base plate, on which a support plate and a pressure plate are provided; the steel strip is placed between the support plate and the pressure plate, and the pressure plate can move relative to the support plate; positioning pieces are symmetrically provided on the outer side of the pressure plate; a group of limiting pieces for positioning the ends of the steel strip are also provided on the outer side of the support plate; a cutting assembly is also provided between the limiting pieces and the support plate; a group of the steel strips are placed on the outer periphery of the support plate in sequence, and the pressure plate limits the steel strips located on the outermost layer, the positioning piece presses the pressure plate tightly against the base plate, the limiting piece presses the ends of the steel strips tightly against the outer periphery of the support plate, the ends of a group of steel strips are welded, and then the cutting assembly cuts off the excess parts of the steel strip group.

[0009] Preferably, both ends of the support plate are arc-shaped and the outer side is straight, and matches the inner side of the pressure plate.

[0010] Preferably, the support plate is fixed to the base plate by bolts; and a cutout is formed on the support plate.

[0011] Preferably, a group of positioning holes for installing positioning pins are formed on the pressure plate, and the positioning pins are located between the positioning members.

[0012] Preferably, the positioning members are two clamps, and the clamps are driven to close to fix the pressing plate to the base plate and to tighten the steel belt group between the pressing plate and the support plate.

[0013] Preferably, there are two limit members, which are push-pull clamps; the two limit members are symmetrically arranged; the limit members are driven to move their ends relative to the support plate, and apply force to the ends of the support plate to reduce the gap between the steel belt groups.

[0014] Preferably, the shape of the output end of the limiting member matches the outer contour of the support plate.

[0015] Preferably, there are two cutting components, each including a cylinder and a cutter, the cutter is fixed to the output end of the cylinder and is driven to move by the cylinder; the distal end of the cutter penetrates into the incision to cut off the excess part of the end of the steel strip group; in the processing state, the two sides of the limit member are respectively in contact with the pressure plate and the cutter.

[0016] The advantages of the technical solution of this utility model are mainly reflected in:

[0017] The steel strip body is pressed between the support plate and the pressure plate, and the two ends are pressed against the outer periphery of the support plate through the limiters, and then the excess part is cut off with the cutting device. It can meet the processing needs of steel strips of different lengths and thicknesses. At the same time, the overall structure is simple, the floor space is small, and the structure is compact.

[0018] The support plate and the bottom plate are connected by bolts. Support plates of different sizes can be replaced for steel strips of different processing lengths, which is highly flexible and has low processing costs.

[0019] It can be applied to pre-tightening multiple layers of steel belts. Theoretical calculations show that when pre-tightening the steel belts, the innermost layer deforms the most and experiences the strongest tension. Deformation gradually decreases from the inside out, leaving the outermost layer with some margin. During motion, if a sudden additional force causes the innermost layer to exceed its allowable tension and break, the second layer will still have pre-tightening force to maintain pre-tightening and connection. The end, with slight deformation, remains in normal condition, enhancing equipment safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The objectives, advantages, and features of the present invention are illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of the application of the technical solutions of the present invention. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

Therefore, they should not be construed as limitations on the present invention.

[0026] like Figures 1 to 4As shown, the present invention discloses a flexible steel strip processing device, comprising a base plate 1, on which a support plate 2 and a pressure plate 3 are arranged. The support plate 2 is fixed to the base plate 1 by bolts. Figure 3 As shown, the support plate 2 has curved ends and a straight outer side, matching the inner side of the pressure plate 3. The steel strip is placed between the support plate 2 and the pressure plate 3, and the pressure plate 3 is movable relative to the support plate 2. Since the support plate 2 is connected to the base plate 1 via bolts, the support plate 2 is removable. Support plates of different sizes can be replaced for different processing lengths of steel strips, providing high flexibility and low processing costs. Furthermore, the steel strip of this utility model preferably uses SUS301EH grade.

[0027] like Figure 2 or Figure 4 As shown, a group of limiters 5 for positioning the ends of the steel strips are also provided on the outside of the support plate 2. The shape of the output end of the limiter 5 matches the outer contour of the support plate 2. There are two limiters 5, and they are preferably push-pull clamps; the two limiters 5 are symmetrically arranged. Since the push-pull clamp is a known structure, it will not be described here; in other embodiments, the limiter can also adopt a cylinder, a slide rail or other components with a linear movement function and cooperate with a moving block that matches the outer contour shape of the support plate 2 to replace the push-pull clamp structure. Drive the limiter 5 so that its end moves relative to the support plate 2, and apply a force to the end of the support plate 2 after contacting the support plate 2 to reduce the gap between the steel strip groups.

[0028] like Figures 1 to 4 As shown, a cutting assembly 6 is further provided between the limiting member 5 and the support plate 2. Specifically, there are two cutting assemblies 6, each comprising a cylinder and a cutter. The cutter is fixed to the output end of the cylinder and is driven to move by the cylinder. Figures 3 and 4 The distal end of the cutter extends into the cutout 20 shown to remove excess portions of the steel strip assembly. Furthermore, the cutting edge of the cutter is preferably angled to reduce contact with the support plate 2, preventing wear on the cutting edge. This also increases pressure on the steel strip assembly during cutting, enabling faster cutting.

[0029] like Figures 1 to 2 As shown, in the processing state, both sides of the limiter 5 abut against the pressing plate 3 and the cutter respectively, and completely match the outer contour of the steel strip group.

[0030] like Figure 1As shown, positioning members 4 are symmetrically arranged on the outside of the pressure plate 3. The positioning members 4 are preferably two clamps, which are driven to close to fix the pressure plate 3 to the base plate 1 and compress the steel belt assembly between the pressure plate 3 and the support plate 2. The pressure plate 3 is formed with a set of positioning holes for installing positioning pins 31, and the positioning pins 31 are located between the positioning members 4.

[0031] The working process of this utility model is as follows:

[0032] Fix the support plate 2 to the base plate 1 with bolts. Then place a group of the steel strips on the outer periphery of the support plate 2 in sequence; and the pressure plate 3 limits the outermost steel strip, that is, the inner contour of the pressure plate 3 abuts against the outer surface of the outermost steel strip, and at the same time applies a force in the direction of the support plate 2, so that the steel strip groups fit tightly together. Start the positioning member 4 to press the pressure plate 3 against the base plate 1, and install the positioning pin 31 on the pressure plate 3 and the base plate 1, so that the overall force on the steel strip group is more uniform. Start the limiting member 5 to press the end of the steel strip against the outer periphery of the support plate 2. Weld the ends of the steel strip group to fix the steel strip group. Then start the cutting assembly 6, and use the cutter in the cutting assembly 6 to cut off the excess part of the end of the steel strip group located in the incision 20.

[0033] The main body of the steel belt is pressed between the support plate and the pressure plate, and the two ends are pressed against the outer periphery of the support plate through limiters. The excess part is then cut off with the cutting device. It can be applied to the processing needs of steel belts of different lengths and thicknesses. At the same time, the overall structure is simple, occupies a small area, and is compact. It can also be applied to the pre-tightening of multiple layers of steel belts. According to theoretical calculations, when the steel belt is pre-tightened, the innermost layer of the steel belt has the largest deformation and the strongest tension. The deformation gradually decreases from the inside to the outside, and the outermost layer still has a margin that is not tightened. When in motion, if there is a sudden additional force that causes the innermost layer of the steel belt to exceed the allowable tension and break, the second layer of the steel belt still has the pre-tightening force to keep the steel belt pre-tightened and connected. The end remains in a normal state with a slight deformation, which increases the safety of the equipment.

[0034] There are many implementation methods for the present utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present utility model.
