Description

Technical Field

[0001] The invention belongs to the technical field of iron plate processing, in particular to a cutting device for iron plate processing. Background Art

[0002] At present, when processing iron plates, it is necessary to cut a longer iron plate raw material into several shorter iron sheets or iron bars for use.

[0003] In the prior art, the fixed-length cutting of iron plate raw materials is mostly achieved with the help of shearing machines. The existing shearing machines use a pressure mechanism to apply pressure to the blade when working, and the blade is pressed to cut the iron plate raw material. However, in order to obtain a number of iron sheets or iron bars of fixed length, after the iron plate raw material is cut, it is necessary to manually adjust the relative position between the iron plate raw material and the blade. However, manual adjustment of the relative position between the iron plate raw material and the blade holder is time-consuming and labor-intensive, resulting in a relatively low cutting efficiency of the iron plate raw material. On the other hand, it is difficult to accurately control the adjustment distance, resulting in different sizes of the cut iron sheets or iron bars, resulting in poor cutting effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] See also Figure 1 , Figure 2 as well as Figure 3 The present embodiment provides a cutting device for iron plate processing, including a support platform 10, a feeding plate assembly 20, a driving assembly 30, a cutter 40 and a pressing assembly 50, wherein the cutter 40 is arranged above the support platform 10, and the driving assembly 30 is installed on the side of the support platform 10, and is used to drive the cutter 40 to move up and down to cut the iron plate, the feeding plate assembly 20 is arranged on the upper part of the support platform 10 and is located on one side of the cutter 40, when the driving assembly 30 drives the cutter 40 to move upward, the feeding plate assembly 20 is used to drive the iron plate to move a certain distance toward the cutter 40 to realize the fixed-distance delivery of the iron plate, the pressing assembly 50 is arranged on the upper part of the support platform 10 and is located on the other side of the cutter 40, when the driving assembly 30 drives the cutter 40 to move downward, the pressing assembly 50 is used to press the iron plate.

[0042] When it is necessary to continuously trim the iron plate, the iron plate to be trimmed can be placed on the upper part of the support platform 10, and then the driving component 30 drives the cutter 40 to move upward, and the feeding plate component 20 is used to drive the iron plate to move a certain distance in the direction of the cutter 40, and then the driving component 30 drives the cutter 40 to move downward, and then the iron plate is cut once. After the iron plate is cut once, the driving component 30 drives the cutter 40 to move upward again, and the feeding plate component 20 is used to drive the iron plate to move a certain distance in the direction of the cutter 40 again, and the driving component 30 drives the cutter 40 to move downward again to cut the iron plate again. Such a reciprocating cycle can realize continuous automatic trimming of the iron plate, so that the longer iron plate is cut into a number of fixed-length iron bars; when the driving component 30 drives the cutter 40 to move downward to cut the iron plate, the iron plate is pressed by the clamping component 50, thereby improving the stability of the iron plate during the cutting process, thereby improving the trimming effect.

[0043] See also Figure 1 , Figure 4 as well as Figure 6 In one embodiment, the driving assembly 30 includes a driving motor 301, a driving gear 302, a transmission gear 303, an incomplete gear 307, a transmission rack 308, a transmission rod 309, a positioning sleeve 310 and a second elastic member 312. The driving motor 301 is fixedly mounted on the bottom of the support platform 10, the driving gear 302 is mounted on the output end of the driving motor 301, the transmission gear 303 is arranged on the side of the support platform 10 and meshes with the driving gear 302, and the incomplete gear 307 is fixedly arranged on the transmission rack 308. On one side of the gear 303, the upper end of the transmission rod 309 extends to the inside of the positioning sleeve 310 and is telescopically matched with the positioning sleeve 310, the lower end of the transmission rod 309 extends to one side of the incomplete gear 307, the transmission rack 308 is fixedly mounted on the side wall of the transmission rod 309 and can engage with the incomplete gear 307, the second elastic member 312 is arranged inside the positioning sleeve 310, and is used to provide elastic pulling force to the transmission rod 309, and the cutter 40 is fixedly mounted on one side of the transmission rod 309 and maintains a vertical distribution.

[0044] When the feeding plate assembly 20 drives the iron plate to move a certain distance in the direction of the cutter 40, the iron plate can move to the position below the cutter 40, and the driving motor 301 drives the driving gear 302 to rotate, and the meshing action of the driving gear 302 and the transmission gear 303 drives the transmission gear 303 and the incomplete gear 307 to rotate. When the incomplete gear 307 rotates, it meshes with the transmission rack 308, and then drives the transmission rod 309 to move downward compared to the positioning sleeve 310. At this time, the second elastic member 312 is stretched, and when the transmission rod 309 moves downward, it drives the cutter 40 to move downward. The cutter 40 moves downward and acts on the iron plate, thereby Cutting process is performed; when the cutting plate is cut, the incomplete gear 307 is disengaged from the transmission rack 308. At this time, under the pull of the second elastic member 312, the transmission rod 309 moves upward compared to the positioning sleeve 310, thereby driving the cutter 40 to move upward. When the cutter 40 moves up, it leaves the iron plate, and then the feeding plate assembly 20 drives the iron plate to move a certain distance in the direction of the cutter 40 to achieve the delivery of the iron plate. When the iron plate is delivered, the incomplete gear 307 is engaged with the transmission rack 308 again, thereby driving the transmission rod 309 to move down again compared to the positioning sleeve 310, thereby driving the cutter 40 to move down again to cut the iron plate again.

[0045] See also Figure 4 In one embodiment, a support rod 311 is fixedly provided on the side wall of the transmission rod 309 , and a mounting rod 401 is fixedly provided on the side wall of the cutter 40 . One end of the mounting rod 401 away from the cutter 40 is fixedly connected to the support rod 311 .

[0046] See also Figure 4 as well as Figure 7 In one embodiment, the clamping assembly 50 includes a movable pressure plate 501, a movable pressure rod 503 and a third elastic member 505. The movable pressure rod 503 vertically penetrates the support rod 311 and movably cooperates with the support rod 311. The movable pressure rod 503 is located below the support rod 311 and is fixedly provided with an annular stopper 504. One end of the third elastic member 505 is connected to the support rod 311, and the other end is connected to the annular stopper 504, which is used to provide elastic support for the movable pressure rod 503. The movable pressure plate 501 is fixedly provided at the lower end of the movable pressure rod 503.

[0047] When the incomplete gear 307 is meshed with the transmission rack 308 and thus drives the support rod 311 and the cutter 40 to move downward, the support rod 311 can also drive the movable pressure rod 503 and the movable pressure plate 501 to move downward synchronously through the third elastic member 505. When the movable pressure plate 501 moves downward, it acts on the iron plate and thus presses the iron plate against the upper part of the support platform 10. After the movable pressure plate 501 presses the iron plate, as the support rod 311 continues to move downward, the support rod 311 moves downward compared to the movable pressure rod 503, the third elastic member 505 is compressed, and the cutter 40 acts on the iron plate and thus cuts the iron plate.

[0048] See also Figure 7 In one embodiment, the movable pressing plate 501 is provided with a slot 502 for the cutter 40 to pass through.

[0049] After the movable pressure plate 501 presses the iron plate, as the support rod 311 drives the cutter 40 to continue to move downward, the cutter 40 can pass through the movable pressure plate 501 from the slot 502, and then cut the iron plate; through the cooperation between the slot 502 and the cutter 40, when the cutter 40 is cutting the iron plate, the movable pressure plate 501 can press the iron plate from both sides of the fracture position of the iron plate, thereby improving the pressing effect of the iron plate, and then improving the cutting effect of the iron plate.

[0050] In one embodiment, a knife groove matching the notch 502 is provided on the upper portion of the support platform 10 below the movable pressure plate 501. Through the setting of the knife groove, the cutting knife 40 can enter the knife groove after passing through the notch 502, thereby allowing the iron plate to be completely cut off.

[0051] See also Figure 1 as well as Figure 4 In one embodiment, a plurality of support rods 103 are fixedly provided on the side wall of the support platform 10, the upper ends of the support rods 103 extend above the support platform 10 and are fixedly provided with a top plate 104, a hanger 105 is fixedly provided at the bottom of the top plate 104, a support shaft 306 is fixedly provided on one side of the transmission gear 303, the incomplete gear 307 is fixedly provided on the outside of the support shaft 306, the end of the support shaft 306 away from the transmission gear 303 passes through the hanger 105 and rotates with the hanger 105, and the positioning sleeve 310 is fixedly provided at the bottom of the top plate 104.

[0052] By setting the support rod 103, the top plate 104 and the hanger 105, rotation support can be provided for the support shaft 306, and then rotation support can be provided for the incomplete gear 303, so that when the driving gear 302 rotates, it can drive the transmission gear 303 and the incomplete gear 307 to rotate smoothly.

[0053] See also Figure 1 , Figure 2 as well as Figure 5 In one embodiment, a plurality of support rollers 101 are rotatably provided on the upper part of the support platform 10, and the plurality of support rollers 101 are used to provide rolling support for the iron plate. The plate feeding assembly 20 includes a plate feeding roller 201 and a limiting plate 202. A plurality of grooves 205 are provided on the circumferential side wall of the plate feeding roller 201 along the length direction, and the plurality of grooves 205 are distributed in a ring-shaped manner. A group of limiting plates 202 are hingedly provided inside each group of the grooves 205, and the limiting plates 202 are in a right-angled triangle structure. A connecting rod 304 is rotatably provided at an eccentric position on one side of the transmission gear 303, and the end of the connecting rod 304 away from the transmission gear 303 is rotatably connected to the end of the plate feeding roller 201.

[0054] When the movable pressing plate 501 acts on the iron plate and presses the iron plate, the plate feeding roller 20 is attached to the upper surface of the iron plate and is located closest to the cutter 40 (such as Figure 2As shown), thereafter, as the transmission gear 303 rotates, the transmission gear 303 pushes one end of the connecting rod 304 and then pushes the plate feeding roller 201 so that the plate feeding roller 201 is away from the cutter 40. During this process, the plate feeding roller 201 rotates relative to the connecting rod 304 and rolls along the upper surface of the iron plate. The inclined surfaces of the plurality of limiting plates 202 in the form of a right-angled triangle act on the upper surface of the iron plate in turn and then deflect toward the corresponding grooves 205 in turn. When the incomplete gear 307 is disengaged from the transmission rack 308, the second elastic member 312 pulls the movable pressing plate 501 to move upward, thereby releasing the pressing plate 501 from the cutting knife 40. When the iron plate is in a compressed state, the plate feeding roller 201 moves to the position farthest from the cutter 40. Thereafter, as the transmission gear 303 continues to rotate, the transmission gear 303 pulls one end of the connecting rod 304 and then pulls the plate feeding roller 201 so that the plate feeding roller 201 is close to the cutter 40. In this process, the straight surface of a group of limiting plates 202 on the circumferential side wall of the plate feeding roller 201 is in contact with the upper surface of the iron plate, thereby providing support for the plate feeding roller 201, so that the rotation of the plate feeding roller 201 is restricted, and the plate feeding roller 201 cannot roll when moving along the upper surface of the iron plate. The friction force applied to the iron plate by the shaft 201 and the set of limit plates 202 drives the iron plate to move toward the cutter 40, and the supporting rollers 101 rotate adaptively. When the plate feeding roller 201 is again in the position closest to the cutter 40, the plate feeding roller 201 is limited by the rotation angle of the connecting rod 304 and is no longer close to the cutter 40, and then the iron plate is fed to the cutter 40 for a fixed distance. Then, the incomplete gear 307 is meshed with the transmission rack 308 again, and the movable pressing plate 501 moves down again to press the fed iron plate again, and the transmission gear 303 pushes one end of the connecting rod 304 to make the feeding roller 201 move closer to the cutter 40. The plate roller 201 rolls along the upper surface of the iron plate again and moves away from the cutter 40 again, and repeats this cycle, thereby realizing continuous and automatic fixed-length delivery of the iron plate, cooperating with the up and down movement of the cutter 40 to cut the longer iron plate into a number of fixed-length iron bars; when the plate feeding roller 201 moves away from the cutter, the movable pressing plate 501 is in a pressing state against the iron plate, and at the same time, the plate feeding roller 201 is in a rolling state along the upper surface of the iron plate, so the friction force applied by the plate feeding roller 201 to the iron plate is very small, and the movement of the plate feeding roller 201 will not cause the iron plate to be displaced, thereby not affecting the cutting of the iron plate.

[0055] See also Figure 5 In one embodiment, a first elastic member 204 is disposed inside each group of the grooves 205 , and the first elastic member 204 is used to provide elastic support for the limiting plate 202 .

[0056] When the plate feeding roller 201 moves away from the cutter 40 and rolls along the upper surface of the iron plate, a number of limit plates 202 are squeezed by the upper surface of the iron plate and then deflected in turn toward the corresponding grooves 205, and the corresponding first elastic members 204 are compressed; when the plate feeding roller 201 approaches the cutter 40, a group of limit plates 202 are supported by the corresponding first elastic members 204 and their facing positions are tightly against the upper surface of the iron plate, so that the friction force applied by the group of limit plates 202 to the upper surface of the iron plate is large enough, and the iron plate can be smoothly driven to move toward the cutter 40 through friction.

[0057] See also Figure 1 as well as Figure 2 In one embodiment, a second rotating shaft 305 is fixedly provided at an eccentric position on one side of the transmission gear 303, a first rotating shaft 203 is fixedly provided at the end of the plate feeding roller 201, one end of the connecting rod 304 is sleeved on the outside of the first rotating shaft 203 and rotatably cooperates with the first rotating shaft 203, and the other end is sleeved on the outside of the second rotating shaft 305 and rotatably cooperates with the second rotating shaft 305.

[0058] When the transmission gear 303 rotates to drive the second rotating shaft 305 to move in a circle, one end of the connecting rod 304 can rotate relative to the second rotating shaft 305, and at the same time, the other end of the connecting rod 304 can rotate relative to the first rotating shaft 203, thereby realizing stable pushing and pulling of the plate feeding roller 201, and further realizing continuous and automatic delivery of the iron plate.

[0059] In one embodiment, the first elastic member 204 , the second elastic member 312 and the third elastic member 505 may be springs or metal springs, which are not limited here.

[0060] See also Figure 1 as well as Figure 2 In one embodiment, a plurality of legs 102 are fixedly provided on the bottom edge of the support platform 10 .

[0061] The working principle of the present invention is as follows:

[0062] When cutting the iron plate, the iron plate to be cut is placed on the upper part of the support platform 10, so that a plurality of support rollers 101 provide rolling support for the iron plate from the bottom of the iron plate, and at the same time, the plate feeding roller 201 is attached to the upper surface of the iron plate, and then the driving motor 301 is started, and the driving motor 301 drives the driving gear 302 to rotate, and through the meshing action of the driving gear 302 and the transmission gear 303, the transmission gear 303, the support shaft 306 and the incomplete gear 307 are driven to rotate. When the incomplete gear 307 rotates, it meshes with the transmission rack 308, and then drives the transmission rod 309 to move downward compared to the positioning sleeve 310, and the transmission rod 309 drives the support rod 311, The cutter 40, the movable pressure rod 503 and the movable pressure plate 501 move downward, and after the movable pressure plate 501 presses the iron plate against the upper part of the support platform 10, the cutter 40 passes through the notch 502 on the movable pressure plate 501 to cut the iron plate once. At the same time, the transmission gear 303 pushes the connecting rod 304, thereby pushing the plate feeding roller 201 away from the cutter 40, and the plate feeding roller 201 rolls along the upper surface of the iron plate; when the iron plate is cut once, the incomplete gear 307 is disengaged from the transmission rack 308, and the second elastic member 312 pulls the transmission rod 309 so that the transmission rod 309 moves up compared to the positioning sleeve 310, thereby driving the support rod 311 and the cutter. 40, the movable pressure rod 503 and the movable pressure plate 501 move up, at this time, the plate feeding roller 201 rolls to the position farthest from the cutter 40, and then the transmission gear 303 pulls the connecting rod 304 and then pulls the plate feeding roller 201 to make the plate feeding roller 201 close to the cutter 40. At this time, the straight position of a group of limiting plates 202 on the circumferential side wall of the plate feeding roller 201 is in contact with the upper surface of the iron plate, thereby limiting the rotation of the plate feeding roller 201. When the plate feeding roller 201 is close to the cutter 40, the friction force applied to the iron plate by the plate feeding roller 201 and the group of limiting plates 202 is used to drive the iron plate to move toward the direction of the cutter 40. The adaptability of a plurality of support rollers 101 The iron plate is rotated to deliver a fixed length toward the cutter 40. When the plate feeding roller 201 moves to the position closest to the cutter 40, the incomplete gear 307 is meshed with the transmission rack 308 again, and then the transmission rod 309, the support rod 311, the cutter 40, the movable pressure rod 503 and the movable pressure plate 501 are driven to move down again. The movable pressure plate 501 presses the iron plate again, and the transmission gear 303 pushes the connecting rod 304 again to make the plate feeding roller 201 move away from the cutter 40 again. At the same time, the cutter 40 passes through the slot 502 again to achieve secondary cutting of the iron plate... This reciprocating cycle is repeated to achieve continuous automatic fixed-length cutting of the iron plate.

[0063] In the embodiment of the present invention, when it is necessary to continuously cut the iron plate, the iron plate to be cut can be placed on the upper part of the support platform 10, and then the driving component 30 drives the cutter 40 to move upward, and at the same time, the feeding plate component 20 is used to drive the iron plate to move a certain distance in the direction of the cutter 40, and then the driving component 30 drives the cutter 40 to move downward, and then the iron plate is cut once. After the iron plate is cut once, the driving component 30 drives the cutter 40 to move upward again, and at the same time, the feeding plate component 20 is used to drive the iron plate to move a certain distance in the direction of the cutter 40 again, and the driving component 30 drives the cutter 40 to move downward again. 0 drives the cutter 40 to move downward again to cut the iron plate again, and such a reciprocating cycle can realize continuous automatic cutting of the iron plate, so that the longer iron plate is cut into a plurality of fixed-length iron bars; when the driving component 30 drives the cutter 40 to move downward to cut the iron plate, the pressing component 50 presses the iron plate, thereby improving the stability of the iron plate during the cutting process, thereby improving the cutting effect. Compared with the prior art, the continuous automatic fixed-length cutting of the iron plate can be realized without excessive manual intervention, and has the advantages of good iron plate cutting effect and high cutting efficiency.
