Description

Technical Field

[0001] The utility model relates to the technical field of iron plate cutting, in particular to an iron plate cutting device. Background Art

[0002] In the process of machining, thin iron plates are used. Thin iron plates usually need to be cut into certain sizes before they can be applied. At present, the cutting of thin iron plates mainly depends on manual operation with tools such as scissors. And during the cutting process, in order to ensure the accuracy of the cutting size, it is necessary to pre-draw lines on the surface of the thin iron plate, which results in troublesome operation, low cutting efficiency, and relatively high labor intensity during long-term work.

[0003] In addition, there are also some iron plate cutting devices. For example, a Chinese utility model patent with the patent number CN200920310592.1 and the patent name of a lever-type thin iron plate cutting knife includes a base, an upper knife rest, a lower knife rest, and a blade. The blades are respectively fixed on the upper knife rest and the lower knife rest, the lower knife rest is fixed on the base, one end of the upper knife rest is rotatably connected to one end of the lower knife rest, the other end of the upper knife rest is connected with a handle, and a handle support rod for supporting the handle is arranged on the base. The handle support rod has a height that ensures the cutting edge of the blade on the upper knife rest is higher than the upper surface of the base. The staff drives the upper knife rest to move downward by pressing the handle, and cooperates with the lower knife rest to cut the thin iron plate. Although it can save effort, the working efficiency is relatively low. Summary of the Utility Model

[0010] As an improved technical solution, the iron plate traction mechanism includes a driving shaft which is rotatably mounted on the support frame. Two driving rollers are fixedly mounted on the driving shaft. The two driving rollers are relatively arranged on both sides of the cutting hole. A space for squeezing and conveying the iron plate is formed between the two driving rollers and the workbench.

[0011] As an improved technical solution, the auxiliary pressing assembly includes a T-shaped slider which is slidably mounted in a T-shaped sliding groove arranged on the support frame. An auxiliary roller is rotatably mounted on one end of the T-shaped slider away from the support frame. A space for auxiliary pressing of the iron plate is formed between the auxiliary roller and the workbench.

[0012] As an improved technical solution, rubber layers for increasing the friction force with the iron plate are arranged on the surfaces of the driving rollers and the auxiliary rollers.

[0013] As an improved technical solution, the adjusting mechanism includes a moving guiding assembly and at least one set of driving assemblies;

[0014] The driving assembly includes a rack which is mounted on the bottom of the jig assembly. A driving wheel meshing with the teeth on the rack is mounted on the output shaft of a third driving motor;

[0015] The moving guiding assembly includes two relatively arranged sliders which are both mounted on the bottom of the jig assembly. The two sliders are respectively slidably mounted on guide rails, and stoppers are mounted at both ends of the guide rails.

[0016] As an improved technical solution, the fixture assembly includes a backing plate, on which support rods are oppositely installed. The support rods all penetrate through the adjustment holes, and the sliders are installed at the ends of the support rods away from the backing plate. At least one connecting rod is connected between the two support rods, and the rack is installed on the connecting rod.

[0017] After adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0018] By providing a workbench, a cutting assembly driven by a pushing device is installed in a lifting manner at the bottom of the workbench. A cutting hole corresponding to the cutting assembly is provided on the workbench. The pushing device can push the cutting assembly to move upward or downward. When the cutting assembly moves upward and exposes the cutting hole, the thin iron plate is cut. When the cutting assembly moves downward, it can be hidden at the bottom of the workbench to reduce safety hazards. A support frame is installed on the top of the workbench, and an iron plate traction mechanism is rotatably installed on the support frame. The iron plate traction mechanism is arranged corresponding to the cutting hole. The thin iron plate can be tractioned by the iron plate traction mechanism, and with the manual boost of the staff, the cutting of the thin iron plate is realized. An auxiliary pressing assembly is also movably installed on the support frame. The thin iron plate can be pressed on the side away from the cutting assembly through the auxiliary pressing assembly, making the movement of the thin iron plate smoother. A fixture assembly is also installed on the workbench. The fixture assembly and the cutting assembly form the required iron plate cutting size. The fixture assembly movably penetrates through the adjustment hole provided on the workbench and is connected to an adjustment mechanism at the bottom. A scale is also installed on the workbench, which is arranged corresponding to the fixture assembly. The position of the fixture assembly can be adjusted through the adjustment mechanism, and then the distance between the fixture assembly and the cutting assembly can be adjusted to meet the requirements of different width specifications. Moreover, the adjustment is convenient and fast. By providing the scale, the adjustment distance of the fixture assembly can be intuitively viewed. Thus, through the above structure, the rapid positioning and cutting of the thin iron plate are realized, the processing efficiency is high, and there is no need for manual drawing and manual cutting, saving time and effort.

[0019] The cutting assembly includes a lifting plate, which is slidably installed on a support seat. The support seat is installed at the bottom of the workbench. A first driving motor is installed on the lifting plate, and a cutting tool is installed on the output shaft of the first driving motor. The cutting tool is arranged corresponding to the cutting hole. The cutting tool can be driven to rotate by the first driving motor. The lifting plate can be pushed to lift and slide along the support seat through the pushing device, so that the cutting tool exposes the cutting hole to realize the cutting of the thin iron plate.

[0020] Limit blocks for limiting the upper limit of the lifting of the cutting assembly are also installed on several support columns. The upward movement stroke of the lifting plate can be limited through the limit blocks to prevent the first driving motor from colliding with the workbench.

[0021] The iron plate traction mechanism includes a driving shaft, which is rotatably installed on the support frame. Two driving rollers are fixedly installed on the driving shaft, and the two driving rollers are relatively arranged on both sides of the cutting hole. One end of the driving shaft penetrates the support frame and is connected to the output shaft of the second driving motor. The driving shaft can be driven to rotate by the second driving motor. During the rotation of the driving shaft, the two driving rollers rotate synchronously, squeezing the thin iron plate and conveying the thin iron plate. At the same time, since the two driving rollers are respectively located on both sides of the cutting hole, when the thin iron plate is cut, a force is applied to the thin iron plate to prevent the thin iron plate from displacing and deforming during cutting;

[0022] The auxiliary pressing assembly includes a T-shaped slider, which is slidably installed in the T-shaped chute provided on the support frame. An auxiliary roller is rotatably installed at one end of the T-shaped slider away from the support frame. A space for auxiliary pressing of the iron plate is formed between the auxiliary roller and the workbench. By setting the T-shaped slider and the T-shaped chute, the position of the auxiliary pressing assembly can be adjusted to suit thin iron plates of different width specifications. When the auxiliary roller presses the thin iron plate by rotatably installing the auxiliary roller on the T-shaped slider, it will not affect the normal movement of the thin iron plate;

[0023] The adjusting mechanism includes a moving guiding assembly and at least one set of driving assemblies. The driving assembly includes a rack, which is installed at the bottom of the fixture assembly. A driving wheel is meshed with the teeth on the rack, and the driving wheel is installed on the output shaft of the third driving motor. The driving wheel can be driven to rotate by the third driving motor. The driving wheel drives the rack to move horizontally through tooth meshing, thereby driving the fixture assembly to move synchronously, realizing the adjustment of the distance between the fixture assembly and the cutting assembly;

[0024] The moving guiding assembly includes two relatively arranged sliders, both of which are installed at the bottom of the fixture assembly. The two sliders are respectively slidably installed on the guide rails, and stoppers are installed at both ends of the guide rails. By setting the sliders and the guide rails, the fixture assembly can move smoothly. At the same time, the moving accuracy of the fixture assembly is ensured. By installing stoppers at both ends of the guide rails, the stoppers can limit the moving stroke of the sliders to prevent the sliders from disengaging from the guide rails.

[0025] In summary, the present utility model provides an iron plate cutting device, which can quickly position and cut thin iron plates according to the required specification dimensions, with high processing efficiency and time-saving and labor-saving. Description of the Drawings

An auxiliary pressing assembly 6 is also movably installed on the support frame 4. The side of the thin iron plate away from the cutting assembly 3 can be pressed by the auxiliary pressing assembly 6 to make the movement of the thin iron plate smoother. A jig assembly 7 is also installed on the workbench 1. A required iron plate cutting size is formed between the jig assembly 7 and the cutting assembly 3. The jig assembly 7 movably penetrates through an adjustment hole 8 provided on the workbench 1 and is connected to an adjustment mechanism at the bottom. A scale 11 is also installed on the workbench 1. The scale 11 is correspondingly arranged with the jig assembly 7. The position of the jig assembly 7 can be adjusted through the adjustment mechanism, and then the distance between the jig assembly 7 and the cutting assembly 3 can be adjusted to meet the requirements of different width specifications. The adjustment is convenient and fast. By setting the scale 11, the adjustment distance of the jig assembly 7 can be intuitively viewed. Thus, through the above structure, the rapid positioning and cutting of the thin iron plate are realized, the processing efficiency is high, and there is no need for manual drawing and manual cutting, saving time and effort.

[0037] Combined with Figures 1-3As shown in the figure, the cutting assembly 3 includes a lifting plate 301. The lifting plate 301 is slidably mounted on the support base through a sleeve. The support base is mounted on the bottom of the workbench 1. A first driving motor 302 is mounted on the lifting plate 301. A cutting tool 303 is mounted on the output shaft of the first driving motor 302. The cutting tool 303 is arranged corresponding to the cutting hole 12. The cutting tool 303 can be driven to rotate by the first driving motor 302. The lifting plate 301 can be pushed by the pushing device 2 to slide up and down on the support base, so that the cutting tool 303 is exposed from the cutting hole 12, realizing the cutting of the thin iron plate.

[0038] Combined with Figures 1-3 As shown in the figure, the support base includes several support columns 304. One end of each of the several support columns 304 is fixed to the bottom of the workbench 1, and the other end is provided with a support plate 305. The pushing device 2 is mounted on the support plate 305. The piston rod of the pushing device 2 is connected to the lifting plate 301. In this embodiment, four support columns 304 are provided, and the four support columns 304 are respectively located at the four corner positions of the support plate 305.

[0039] Combined with Figures 1-3 As shown in the figure, a limit block 306 for limiting the upper limit of the lifting of the cutting assembly 3 is further mounted on several support columns 304. A bolt is mounted on the side wall of the limit block 306. The limit block 306 is locked to the support column 304 through the bolt. The position of the limit block 306 can be adjusted by loosening the bolt. The upward movement stroke of the lifting plate 301 can be limited by the limit block 306, avoiding the first driving motor 302 from colliding with the workbench 1.

[0040] Combined with Figures 1-3 As shown in the figure, the iron plate traction mechanism 5 includes a driving shaft 501. The driving shaft 501 is rotatably mounted on the support frame 4 through a bearing. Two driving rollers 502 are fixedly mounted on the driving shaft 501. The two driving rollers 502 are relatively arranged on both sides of the cutting hole 12. A space for squeezing and conveying the iron plate is formed between the two driving rollers 502 and the workbench 1. One end of the driving shaft 501 penetrates through the support frame 4 and is connected to the output shaft of the second driving motor 503. The second driving motor 503 is mounted on the support frame 4. The driving shaft 501 can be driven to rotate by the second driving motor 503. The two driving rollers 502 rotate synchronously when the driving shaft 501 rotates. The two driving rollers 502 squeeze the thin iron plate and convey the thin iron plate. At the same time, since the two driving rollers 502 are respectively located on both sides of the cutting hole 12, a force is applied to the thin iron plate during the cutting of the thin iron plate, avoiding the displacement and deformation of the thin iron plate during cutting.

[0041] Combined with Figures 1-3As shown in the figure, the auxiliary pressing assembly 6 includes a T-shaped slider 601 which is slidably installed in a T-shaped chute 602 provided on the support frame 4. One end of the T-shaped slider 601 away from the support frame 4 is rotatably installed with an auxiliary roller 603. A space for auxiliary pressing of the iron plate is formed between the auxiliary roller 603 and the workbench 1. By providing the T-shaped slider 601 and the T-shaped chute 602, the position of the auxiliary pressing assembly 6 can be adjusted to accommodate thin iron plates of different width specifications. When the auxiliary roller 603 is rotatably installed on the T-shaped slider 601 and presses the thin iron plate, it will not affect the normal movement of the thin iron plate.

[0042] Combined with Figures 1-3 As shown in the figure, rubber layers for increasing the friction force between the driving roller 502 and the iron plate are provided on the surfaces of the driving roller 502 and the auxiliary roller 603. By providing the rubber layers, the friction force between the driving roller 502 and the auxiliary roller 603 and the thin iron plate is increased, which is convenient for the conveying and movement of the thin iron plate.

[0043] Combined with Figures 1-3 As shown in the figure, the adjusting mechanism includes a moving guiding assembly 9 and at least one set of driving assemblies 10;

[0044] The driving assembly 10 includes a rack 1001 which is installed at the bottom of the fixture assembly 7 by welding. A driving wheel 1002 meshes with the teeth on the rack 1001. The driving wheel 1002 is installed on the output shaft of a third driving motor 1003. The third driving motor 1003 is installed on the ground through a base. The third driving motor 1003 can drive the driving wheel 1002 to rotate. The driving wheel 1002 drives the rack 1001 to move horizontally through tooth meshing, thereby driving the fixture assembly 7 to move synchronously, realizing the adjustment of the distance between the fixture assembly 7 and the cutting assembly 3;

[0045] The moving guiding assembly 9 includes two relatively arranged sliders 901. Both sliders 901 are installed at the bottom of the fixture assembly 7. The two sliders 901 are respectively slidably installed on a guide rail 902. Stoppers 903 are installed at both ends of the guide rail 902. By providing the sliders 901 and the guide rail 902, the fixture assembly 7 can move smoothly. At the same time, the moving accuracy of the fixture assembly 7 is ensured. By installing the stoppers 903 at both ends of the guide rail 902, the stoppers 903 can limit the moving stroke of the sliders 901 and prevent the sliders 901 from disengaging from the guide rail 902.

[0046] Combined with Figures 1-3 As shown in the figure, the fixture assembly 7 includes a backing plate 701. Support rods 702 are oppositely installed on the backing plate 701. The support rods 702 all penetrate through the adjusting holes 8. The sliders 901 are fixedly installed at one ends of the support rods 702 away from the backing plate 701. At least one connecting rod 703 is connected between the two support rods 702. The rack 1001 is installed on the connecting rod 703.

[0047] For the sake of easy understanding, the working process of this embodiment is given below:

[0048] Combined with Figures 1-3 As shown, first, according to the width dimension of the required thin iron plate, the third driving motor 1003 drives the driving wheel 1002 to rotate. The driving wheel 1002 drives the rack 1001 to move horizontally through gear teeth meshing. Since the rack 1001 is installed at the bottom of the fixture assembly 7, and at the same time, the bottom of the fixture assembly 7 is also installed on the slide rail through the slider 901, thus, the fixture assembly 7 can be driven to move synchronously, and then the distance between the fixture assembly 7 and the cutting assembly 3 can be adjusted. At the same time, by corresponding to the scale between the fixture assembly 7 and the scale ruler 11, the distance between the fixture assembly 7 and the cutting assembly 3 is made equal to the width dimension of the required thin iron plate. After that, the thin iron plate is placed on the workbench 1, and one side abuts against the backing plate 701 of the fixture assembly 7. Then, the first driving motor 302 is started, and the first driving motor 302 drives the cutting tool 303 to rotate. At the same time, the piston rod of the pushing device 2 extends and pushes the lifting plate 301 upward to expose the cutting tool 303 from the cutting hole 12. Then, the second driving motor 503 is started, and the second driving motor 503 drives the driving shaft 501 to rotate. The driving shaft 501 drives the two driving rollers 502 to rotate synchronously. At this time, the operator manually pushes the thin iron plate to move along the backing plate 701. During the movement of the thin iron plate, the two driving rollers 502 will squeeze and pull the thin iron plate to move. At the same time, the auxiliary roller 603 of the auxiliary pressing assembly 6 makes the end of the thin iron plate away from the cutting tool 303 closely adhere to the workbench 1 without affecting the movement of the thin iron plate. During the movement of the thin iron plate, the cutting tool 303 cuts the thin iron plate.

[0049] In summary, the present utility model provides an iron plate cutting device, which can quickly position and cut the thin iron plate according to the required specification dimensions, with high processing efficiency and time-saving and labor-saving.
