Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel strip cutting technology, and in particular to a cutting device for cold-rolled steel strip. Background Technology

[0002] Cold-rolled strip steel refers to steel strip and sheet produced by cold rolling at room temperature using hot-rolled strip steel and steel plate as raw materials. The thickness is generally 0.1 to 3 mm and the width is 100 to 2000 mm. Cold-rolled strip or sheet has advantages such as good surface finish, good flatness, high dimensional accuracy and good mechanical properties. Cutting is an indispensable and important step in steel strip processing. Steel strip needs to be cut before or after rolling.

[0003] However, in practical applications, there are still some unresolved problems. The following are some common problems with cutting equipment for cold-rolled steel strip: In the existing technology, after the cold-rolled steel strip is cut, it is impossible to deal with the sharp burrs that will be generated on the edge of the cold-rolled steel strip. Usually, the cut cold-rolled steel strip is transported to the corresponding grinding equipment for grinding to remove the burrs. During this process, the sharp burrs can easily penetrate the gloves and injure the workers, which is dangerous. It not only reduces work efficiency, but also causes injury to the operators.

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides a cutting device for cold-rolled steel strip. The cutting device for cold-rolled steel strip includes a support mechanism 100, a cutting and grinding mechanism 200, and a fixing mechanism 300. The support mechanism 100 can place and support the cold-rolled steel strip, the cutting and grinding mechanism 200 can grind the cold-rolled steel strip after cutting, and the fixing mechanism 300 can fix the cold-rolled steel strip during the cutting and grinding process.

[0031] Specifically, the support mechanism 100 includes a platform 101 and a roller 102, with the roller 102 rotatably connected to the surface of the platform 101.

[0032] The cold-rolled steel strip to be cut is placed and supported by the platform 101. There are several rollers 102, which are rotatably connected to the surface of the platform 101 through bearings. The number of rollers 102 can be set according to the actual situation. The rollers 102 reduce the obstruction when the cold-rolled steel strip moves, reduce the pressure required when moving, and reduce the labor intensity. The rollers 102 can be rotated by an external drive device to mechanically transport the cold-rolled steel strip.

[0033] Specifically, the cutting and grinding mechanism 200 is installed on the surface of the platform 101 and includes a vertical rod 201, a support plate 202, a driving component 203, a guide component 204, and a cutting and grinding component 205. The vertical rod 201 is fixedly connected to the top of the platform 101, the support plate 202 is fixedly connected to the upper end of the vertical rod 201, the driving component 203 is installed on the surface of the support plate 202, the cutting and grinding component 205 is disposed on the surface of the driving component 203, and the guide component 204 is disposed on the top of the driving component 203.

[0034] There are four vertical rods 201. The top of the support plate 202 has a square hole so that the movable plate 204c can move without obstruction. The reciprocating movement of the movable plate 203d, the movable plate 204c and the cutting and grinding component 205 is realized by the driving component 203, so that the cutting and grinding component 205 can cut the cold-rolled steel strip and grind the burrs generated at the cut edge.

[0035] The guide 204 prevents the grinding disc 205b from contacting the cold-rolled steel strip during the cutting process of the cutting and grinding part 205. When the cutting and grinding part 205 is reset, the grinding disc 205b contacts the cold-rolled steel strip, so that the rotating grinding disc 205b grinds and polishes the burrs generated at the cutting edge.

[0036] Specifically, the fixing mechanism 300 is installed on the surface of the vertical rod 201 and includes a force-applying component 301 and a pressing component 302. The force-applying component 301 is disposed on the surface of the driving component 203, and the pressing component 302 is disposed on the surface of the vertical rod 201.

[0037] During the cutting and grinding processes, the force-applying component 301 acts on the holding component 302, causing the holding component 302 to hold and fix the cold-rolled steel strip. When the cutting or grinding is completed, the holding component 302 can lose its holding and fixing of the cold-rolled steel strip, without affecting the movement of the cold-rolled steel strip after cutting and grinding. It can hold and fix when processing is required and release when movement is required, without affecting normal operation and with strong continuity.

[0038] Example 2

[0039] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, a limiting plate 103 is fixedly connected to the top of the platform 101, and a collection frame 104 is inserted into the surface of the platform 101.

[0041] There are four limiting plates 103, which are fixed to the top of the platform 101 by bolts. The distance between two opposite limiting plates 103 can be adjusted according to the actual width of the cold-rolled steel strip. The limiting plates 103 limit the side of the cold-rolled steel strip. The collection frame 104 collects the debris that falls into the platform 101 during cutting and grinding.

[0042] The driving component 203 includes a mounting block 203a, a first motor 203b, a lead screw 203c, and a moving plate 203d. The mounting block 203a is mounted on the top of the support plate 202. The first motor 203b is fixedly connected to the surface of the mounting block 203a. The output shaft of the first motor 203b is fixedly connected to one end of the lead screw 203c. The other end of the lead screw 203c is rotatably connected to the surface of the mounting block 203a. The moving plate 203d is threadedly connected to the surface of the lead screw 203c.

[0043] There are two mounting blocks 203a, which are fixed to the top of the support plate 202 by bolts. The lead screw 203c is rotatably connected to the surface of the mounting block 203a through a bearing. The first motor 203b is a servo motor. The first motor 203b drives the lead screw 203c to rotate, thereby moving the moving plate 203d. The moving direction of the moving plate 203d is adjusted according to the forward and reverse rotation of the output shaft of the first motor 203b.

[0044] A pulley 203e is rotatably connected to the surface of the movable plate 203d, and a guide rod 203f is slidably connected to the surface of the movable plate 203d. The guide rod 203f is fixedly connected to the surface of the mounting block 203a.

[0045] The guide rod 203f passes through the movable plate 203d and is slidably connected to it. The guide rod 203f guides and limits the movable plate 203d. There are four pulleys 203e, which are rotatably connected to the surface of the movable plate 203d through a rotating shaft. The pulleys 203e support the movable plate 203d, reduce the force on the lead screw 203c, and protect it.

[0046] The guide component 204 includes a guide rail 204a, a limiting component 204b, and a movable plate 204c. The guide rail 204a is mounted on the top of the mounting block 203a. The movable plate 204c is slidably connected to the surface of the moving plate 203d. The limiting component 204b is mounted on the upper end of the movable plate 204c. The cutting and grinding component 205 is mounted on the lower end of the movable plate 204c.

[0047] The movable plate 204c passes through and slides through the movable plate 203d. The movable plate 204c moves as the movable plate 203d moves, which in turn causes the limiting member 204b to move on the surface of the guide rail 204a. This allows the position of the movable plate 204c at both ends of the guide rail 204a to be changed, thereby adjusting the height of the cutting and grinding part 205 and achieving different functions when moving back and forth.

[0048] The guide rail component 204a includes a square plate 204a-1, a guide groove 204a-2, and an anti-backward block 204a-3. The square plate 204a-1 is fixedly connected to the top of the mounting block 203a, the guide groove 204a-2 is formed on the surface of the square plate 204a-1, and the anti-backward block 204a-3 is fixedly connected to the inner wall of the guide groove 204a-2.

[0049] There are two anti-backward blocks 204a-3. With the movement of the moving plate 203d and the movement of the movable plate 204c driven by the guide groove 204a-2, and with the cooperation of the limiting member 204b, the movable plate 204c moves along the trajectory of the guide groove 204a-2, thereby adjusting the moving height of the cutting and grinding part 205. This controls the direction of the cutting operation to be the outward direction and the direction of the grinding operation to be the return direction.

[0050] When the limiting member 204b moves to both ends within the guide groove 204a-2 via the anti-backward block 204a-3, it will not move back along the original path when it moves again, and the height adjustment of the corresponding movable plate 204c is completed at both ends.

[0051] The limiting component 204b includes a square rod 204b-1, a round block 204b-2, a roller 204b-3, and a first spring 204b-4. The square rod 204b-1 is slidably connected to the surface of the movable plate 204c. The round block 204b-2 is fixedly connected to one end of the square rod 204b-1. The roller 204b-3 is rotatably connected to the other end of the square rod 204b-1 and is movably connected to the guide groove 204a-2. The first spring 204b-4 is sleeved on the surface of the square rod 204b-1, and its two ends are fixedly connected to the surfaces of the movable plate 204c and the round block 204b-2, respectively.

[0052] The square rod 204b-1 passes through the movable plate 204c and is slidably connected to it. The roller 204b-3 is rotatably connected to the square rod 204b-1 through a rotating shaft. The square rod 204b-1 can guide and limit the roller 204b-3. The first spring 204b-4 keeps the roller 204b-3 in constant contact with the guide groove 204a-2 under its elastic force. The roller 204b-3 can move when the anti-backward block 204a-3 squeezes it. When it is separated from the anti-backward block 204a-3, it rebounds. Under the action of the convex part of the anti-backward block 204a-3, the roller 204b-3 will not retreat along the incoming path.

[0053] The cutting and grinding component 205 includes a second motor 205a, a grinding disc 205b, and a cutting disc 205c. The second motor 205a is fixedly connected to the surface of the movable plate 204c, the grinding disc 205b is fixedly connected to the output shaft of the second motor 205a, and the cutting disc 205c is fixedly connected to the surface of the grinding disc 205b.

[0054] The rotation of the output shaft of the second motor 205a can drive the rotation of the cutting disc 205c and the grinding disc 205b. The rotation of the cutting disc 205c cuts the cold-rolled steel strip, and the grinding disc 205b, which moves down and rotates, polishes the burrs generated at the cut edge.

[0055] The force-applying component 301 includes a connecting plate 301a and a pressure roller 301b. The upper end of the connecting plate 301a is fixedly connected to the surface of the movable plate 203d, and the pressure roller 301b is rotatably connected to the lower end surface of the connecting plate 301a.

[0056] The pressure roller 301b is rotatably connected to the surface of the connecting plate 301a via a bearing. When the connecting plate 301a moves, it can drive the pressure roller 301b to move. The movement of the pressure roller 301b moves and squeezes the trapezoidal plate 302b, causing the trapezoidal plate 302b and the horizontal plate 302a to move downward. The pressure roller 301b can reduce friction and better move and squeeze the trapezoidal plate 302b.

[0057] The holding member 302 includes a horizontal plate 302a, a trapezoidal plate 302b, a fixing rod 302c, a pressure plate 302d, a rubber pad 302e, and a second spring 302f. The horizontal plate 302a is sleeved on the surface of the vertical rod 201. The trapezoidal plate 302b is fixedly connected to the top of the horizontal plate 302a. The fixing rod 302c is fixedly connected between the bottom of the horizontal plate 302a and the top of the pressure plate 302d. The rubber pad 302e is fixedly connected to the bottom of the pressure plate 302d. The second spring 302f is sleeved on the surface of the vertical rod 201.

[0058] The horizontal plate 302a is slidably connected to the surface of the vertical rod 201. The horizontal plate 302a and the pressure plate 302d are indirectly connected by the fixed rod 302c, so that they can move synchronously. The trapezoidal plate 302b moves downward under the action of the pressure roller 301b, which in turn causes the fixed rod 302c, the pressure plate 302d and the rubber pad 302e to move downward. The downward movement of the rubber pad 302e presses down on the cold-rolled steel strip. At the same time, under the continuous squeezing action of the pressure plate 302d, the rubber pad 302e can undergo slight deformation, so that the pressure roller 301b can move to the top horizontal position of the trapezoidal plate 302b.

[0059] The second spring 302f resets the horizontal plate 302a, the fixing rod 302c, the pressure plate 302d and the rubber pad 302e when the pressure roller 301b disengages from the trapezoidal plate 302b, thereby causing the rubber pad 302e to detach from the surface of the cold-rolled steel strip.

[0060] In use, the position of the cold-rolled steel strip to be cut is moved to the relative position of the cutting disc 205c by the roller 102, and the operation of the first motor 203b and the second motor 205a is controlled. The rotation of the output shaft of the second motor 205a drives the rotation of the cutting disc 205c and the grinding disc 205b. The forward rotation of the output shaft of the first motor 203b drives the rotation of the lead screw 203c. Under the guidance and limiting action of the guide rod 203f, the moving plate 203d, the pulley 203e, the connecting plate 301a, the movable plate 204c, the limiting member 204b and the cutting and grinding member 205 are moved.

[0061] The movement of the connecting plate 301a drives the pressure roller 301b to move and press the trapezoidal plate 302b, causing the trapezoidal plate 302b, the horizontal plate 302a, the fixing rod 302c, the pressure plate 302d, and the rubber pad 302e to move downwards, and the second spring 302f to compress. When the pressure roller 301b moves to the top horizontal plane of the trapezoidal plate 302b, the horizontal plate 302a, the fixing rod 302c, and the pressure plate 302d no longer move downwards, and the cold-rolled steel strip is fixed by the rubber pad 302e. At this time, the rotating cutting disc 205c is not in contact with the cold-rolled steel strip. As the moving plate 203d drives the moving plate 204c and the cutting and grinding part 205 to move, the rotating cutting disc 205c cuts the cold-rolled steel strip.

[0062] After cutting is completed, the pressure roller 301b disengages from the trapezoidal plate 302b. Under the action of the second spring 302f, the horizontal plate 302a, the fixed rod 302c, the pressure plate 302d, and the rubber pad 302e are reset. When the roller 204b-3 moves in the guide groove 204a-2 and comes into contact with the anti-backward block 204a-3, it is squeezed, causing the square rod 204b-1 and the round block 204b-2 to move, and the first spring 204b-4 to compress. When the cutting is completed and the roller 204b-3 moves to the end, it disengages from the anti-backward block 204a-3. When the roller 204b-3 is in the arc transition area at the end of the guide groove 204a-2, the limiting member 204b, the movable plate 204c, and the cutting and grinding member 205 move down, so that the grinding disc 205b comes into contact with the cold-rolled steel strip.

[0063] The reverse rotation of the output shaft of the first motor 203b is controlled. Similarly, during the process of the lead screw 203c rotating in the reverse direction to drive the moving plate 203d to reset, the rubber pad 302e on the fixing mechanism 300 moves down to press and fix the cold-rolled steel strip. The moving and rotating grinding disc 205b grinds and polishes the burrs generated at the cutting edge. When it moves to the end, it is the same as when cutting. The positions of the moving plate 204c, the limiting part 204b and the cutting and grinding part 205 are adjusted. The cutting and grinding operation is completed through a back-and-forth process. The operation can be repeated.

[0064] In summary, the cutting and grinding mechanism 200 can grind the cold-rolled steel strip after cutting, polishing the sharp burrs generated by the cutting edge. Compared with the prior art, it is not necessary to transport the cut cold-rolled steel strip to the corresponding grinding equipment for grinding and burr removal, which improves work efficiency and reduces the probability of injury to operators. The fixing mechanism 300 can fix the cold-rolled steel strip during the cutting and grinding process, which makes the cold-rolled steel strip less prone to positional displacement compared with the prior art, improves cutting accuracy, and ensures the flatness of the cut surface.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
