[0030] As Figure 1 And Figure 2 As shown in the description of the utility model, the cutting machine according to the first aspect embodiment of the utility model comprises a rack 100, a cutting table 200, a cutting device 300 and a feeding table 400, the feeding table 400 is used for conveying materials to the cutting table 200, the cutting table 200 is used for clamping materials to be slitting, and the cutting device 300 is used for slitting the materials. In the embodiment, the length direction of the rack 100 is regarded as the front-rear direction, the cutting table 200 is located in front of the feeding table 400, and the feeding table 400 has a feeding direction from back to front; the width direction of the rack 100 is regarded as the left-right direction, the cutting device 300 is provided with a cutting knife 310 moving along the left-right direction, so that the materials are slitted into a plurality of cutting pieces; and the height direction of the rack 100 is regarded as the up-down direction.

[0031] Exemplarily, two linear sliding rails 110 are arranged on the rack 100, and the two linear sliding rails 110 are arranged along the front-rear direction; correspondingly, the bottom surface of the feeding table 400 is provided with two groups of linear sliding blocks 411, and the two groups of linear sliding blocks 411 of the feeding table 400 are respectively connected to the two linear sliding rails 110 in a sliding mode, so that the feeding table 400 can be connected to the rack 100 in a sliding mode along the front-rear direction. Furthermore, the rack 100 is connected with a lead screw 120 arranged along the front-rear direction, the end of the lead screw 120 is connected with a feeding motor 121, and the feeding table 400 is provided with a nut seat 121 connected to the lead screw 120. When the feeding motor 121 is started, the lead screw 120 rotates under the drive of the feeding motor 121, and since there is only a rotation degree of freedom between the lead screw 120 and the rack 100, the rotation of the lead screw 120 can drive the nut seat 121 to move along the length direction of the lead screw 120, so as to realize the feeding table 400 advancing or retreating.

[0032] As Figures 3 to 5As shown, since the material to be cut is generally a profile, which has a regular shape, the feeding table 400 is provided with a second transverse positioning surface 440 and a second vertical positioning surface 450, which are orthogonal to each other. The feeding table 400 is configured with a second longitudinal clamp 460 and a second transverse clamp 470, the second transverse positioning surface 440 is located in the moving direction of the second longitudinal clamp 460, i.e. the second longitudinal clamp 460 can press the profile down on the second transverse positioning surface 440; the second vertical positioning surface 450 is located in the moving direction of the second transverse clamp 470, i.e. the second transverse clamp 470 can drive the profile to move towards the direction of the second vertical positioning surface 450 to realize the transverse positioning of the profile.

[0033] Further, the second longitudinal clamp 460 and the second transverse clamp 470 can be selected as air cylinders, which are provided with a telescopic part that can linearly extend and retract, the end of the telescopic part is connected with a second pressing plate 461, the second pressing plate 461 of the second longitudinal clamp 460 is arranged in the horizontal direction, and the second pressing plate 461 of the second transverse clamp 470 is arranged in the vertical direction. In order to protect the surface of the profile, all the second pressing plates 461 are connected with a second rubber plate 462, the second transverse positioning surface 440 is connected with a first backing plate 441, and the second vertical positioning surface 450 is connected with a second backing plate 451, the second rubber plate 462, the first backing plate 441 and the second backing plate 451 can be selected as TPU rubber pads.

[0034] Before the feeding table 400 forwards the profile, the second transverse clamp 470 of the feeding table 400 drives the profile to move towards the direction of the second vertical positioning surface 450 to realize the transverse positioning of the profile, and then the second longitudinal clamp 460 of the feeding table 400 presses the profile down on the second transverse positioning surface 440 to realize the longitudinal positioning of the profile. Since the profile is clamped and positioned by the clamp of the feeding table 400, when the feeding table 400 moves towards the cutting table 200 under the driving of the feeding motor 121, the profile is also synchronously forwarded, so that the profile can be fed by the feeding table 400, and the feeding parameters are controlled by the feeding motor 121 to meet the requirements of numerical control.

[0035] As shown in Figure 1 and Figure 2 Exemplarily, the rack 100 is configured with a cutting device 300, which can be selected from the prior art, and has a high-speed rotating cutting knife 310 that moves in the left-right direction. The profile is forwarded under the driving of the feeding table 400, and the moving path of the cutting knife 310 intersects with the moving path of the profile to realize the slitting of the profile.

[0036] Exemplarily, the rack 100 is provided with cutting tables 200 on both sides of the cutting device 300, in the embodiment, the cutting table 200 on the rear side of the cutting device 300 is defined as the feeding cutting table 210, and the cutting table 200 on the front side of the cutting device 300 is defined as the discharging cutting table 220. A cutting space capable of accommodating the cutting knife 310 is reserved between the feeding cutting table 210 and the discharging cutting table 220, so as to prevent the cutting table 200 from being damaged by the high-speed rotating cutting knife 310. Both of the cutting tables 200 are provided with a first horizontal positioning surface 230 and a first vertical positioning surface 240, the first horizontal positioning surface 230 is perpendicular to the first vertical positioning surface 240, the first horizontal positioning surfaces 230 of the two cutting tables 200 are aligned with each other, the first vertical positioning surfaces 240 of the two cutting tables 200 are aligned with each other, the second horizontal positioning surface 440 of the feeding table 400 is flush with the first horizontal positioning surface 230 of the cutting table 200, and the second vertical positioning surface 450 of the feeding table 400 is flush with the first vertical positioning surface 240 of the cutting table 200. Each cutting table 200 is provided with a first longitudinal clamp 250 and a first horizontal clamp 260, the first horizontal positioning surface 230 is located in the moving direction of the first longitudinal clamp 250, that is, the first longitudinal clamp 250 can press the profile downward on the first horizontal positioning surface 230; the first vertical positioning surface 240 is located in the moving direction of the first horizontal clamp 260, that is, the first horizontal clamp 260 can drive the profile to move toward the direction of the first vertical positioning surface 240, so as to realize the horizontal positioning of the profile.

[0037] Further, the first longitudinal clamp 250 and the first horizontal clamp 260 can be selected as air cylinders, which are provided with telescopic parts capable of linearly extending and retracting, the telescopic parts are connected with first pressing plates 261 at the ends, the first pressing plate 261 of the first longitudinal clamp 250 is arranged in the horizontal direction, and the first pressing plate 261 of the first horizontal clamp 260 is arranged in the vertical direction. In order to protect the surface of the profile, all the first pressing plates 261 are connected with first rubber plates 262, the first horizontal positioning surface 230 is connected with a first backing plate 441, and the first vertical positioning surface 240 is connected with a second backing plate 451, the first rubber plate 262, the first backing plate 441 and the second backing plate 451 can be selected as TPU rubber pads. Since the first horizontal positioning surface 230 and the second horizontal positioning surface 440 are horizontal positioning reference surfaces, and the first vertical positioning surface 240 and the second vertical positioning surface 450 are vertical positioning reference surfaces, the first backing plate 441 of the first horizontal positioning surface 230 and the first backing plate 441 of the second horizontal positioning surface 440 need to have the same thickness, and the second backing plate 451 of the first vertical positioning surface 240 and the second backing plate 451 of the second vertical positioning surface 450 need to have the same thickness.

[0038] In the present embodiment, since the first lateral positioning surface 230 is replaced by the first pad plate 441 and the first vertical positioning surface 240 is replaced by the second pad plate 451, the first pad plate 441 of the cutting table 200 can be regarded as the first lateral positioning surface 230 and the second pad plate 451 of the cutting table 200 can be regarded as the first vertical positioning surface 240. Since the second lateral positioning surface 440 is replaced by the first pad plate 441 and the second vertical positioning surface 450 is replaced by the second pad plate 451, the first pad plate 441 of the feeding table 400 can be regarded as the second lateral positioning surface 440 and the second pad plate 451 of the feeding table 400 can be regarded as the second vertical positioning surface 450.

[0039] When the feeding table 400 forwards the profile by a certain distance, the clamp of the feeding table 400 loosens the clamping of the profile, and then the first lateral clamp 260 of the feeding cutting table 210 and the discharging cutting table 220 drives the profile to move towards the first vertical positioning surface 240 to realize the lateral positioning of the profile, and then the first longitudinal clamp 250 of the feeding cutting table 210 and the discharging cutting table 220 presses the profile downwards on the first lateral positioning surface 230 to complete the clamping of the profile before the slitting, so as to offset the force of the cutting knife 310 when slitting the profile, and avoid the position of the profile from being deviated in the slitting process. Finally, the cut profile moves in the discharging direction under the pushing of the subsequent profile.

[0040] In other embodiments, the cutting table 200 can also be provided only with the first longitudinal clamp 250 without the first lateral clamp 260, and in this case, the lateral positioning of the profile mainly relies on the feeding table 400, but this has a higher technical requirement for the feeding table 400.

[0041] Although the above structure can realize the continuous slitting of the profile, it is not enough to solve various problems caused by scratching of the profile during slitting. In order to solve the problem of scratching between the profile and other parts, such as Figures 3 to 5As shown, the feeding table 400 is provided with a longitudinal moving unit 480 and a transverse moving unit 490. The longitudinal moving unit 480 drives the feeding table 400 to move in the up-down direction, so that the second transverse positioning surface 440 has a moving path flush with the first transverse positioning surface 230. The transverse moving unit 490 drives the feeding table 400 to move in the left-right direction, so that the second vertical positioning surface 450 has a moving path flush with the first vertical positioning surface 240. In the embodiment, the feeding table 400 has three longitudinal heights under the driving of the longitudinal moving unit 480. At this time, the second transverse positioning surface 440 has a longitudinal height flush with the first transverse positioning surface 230, a longitudinal height higher than the first transverse positioning surface 230, or a longitudinal height lower than the first transverse positioning surface 230. That is, the second transverse positioning surface 440 has three height gears, corresponding to higher than, flush with, and lower than the first transverse positioning surface 230 respectively. The feeding table 400 has three transverse positions under the driving of the transverse moving unit 490. At this time, the second vertical positioning surface 450 has a transverse position flush with the first vertical positioning surface 240, a transverse position left to the first vertical positioning surface 240, or a transverse position right to the first vertical positioning surface 240. That is, the second vertical positioning surface 450 has three position gears, corresponding to left to, flush with, and right to the first vertical positioning surface 240 respectively.

[0042] Specifically, the feeding table 400 comprises a base plate 410, a movable plate 420, and a lifting plate 430. The bottom surface of the base plate 410 is provided with two groups of linear slides 411 to be slidably connected with two slide rails on the rack 100. The base plate 410 is provided with the movable plate 420 moving in the left-right direction. The two are movably connected through a sliding groove and a sliding block. The movable plate 420 has only a degree of freedom in the left-right direction with the base plate 410. The movable plate 420 is installed with longitudinal moving units 480. The number of the longitudinal moving units 480 is multiple, which can be air cylinders. The extension parts of all the air cylinders are jointly connected with the lifting plate 430. The lifting plate 430 has a second transverse positioning surface 440. The surface of the lifting plate 430 is connected with a first backing plate 441. The edge of the lifting plate 430 is connected with a vertical plate 431. The vertical plate 431 has a second vertical positioning surface 450. The surface of the vertical plate 431 is connected with a second backing plate 451. When the lifting plate 430 is moved upward from a longitudinal reference position under the driving of the longitudinal moving units 480, the second transverse positioning surface 440 is higher than the first transverse positioning surface 230 at this time. When the lifting plate 430 is moved downward from the longitudinal reference position under the driving of the longitudinal moving units 480, the second transverse positioning surface 440 is lower than the first transverse positioning surface 230 at this time. When the lifting plate 430 is reset to the longitudinal reference position under the driving of the longitudinal moving units 480, the second transverse positioning surface 440 is flush with the first transverse positioning surface 230 at this time.

[0043] In addition, the nut seat 121 is provided with a plurality of transverse movement units 490, which can be air cylinders, and the extension and retraction of all the air cylinders are connected to the movable plate 420. When the movable plate 420 is moved to the left from the transverse reference position by the transverse movement units 490, the second vertical positioning surface 450 is to the left of the first vertical positioning surface 240 at this time; when the movable plate 420 is moved to the right from the transverse reference position by the transverse movement units 490, the second vertical positioning surface 450 is to the right of the first vertical positioning surface 240 at this time; when the movable plate 420 is returned to the transverse reference position by the transverse movement units 490, the second vertical positioning surface 450 is flush with the first vertical positioning surface 240 at this time.

[0044] It can be understood that the feeding table 400 can also have more than three longitudinal heights under the drive of the longitudinal movement units 480, and the feeding table 400 can also have more than three transverse positions under the drive of the transverse movement units 490, without being limited to the above-mentioned embodiments.

[0045] With the above structure, during the feeding of the feeding table 400, the transverse moving unit 490 drives the feeding table 400 to move in the opposite direction of the transverse clamping, and the longitudinal moving unit 480 drives the feeding table 400 to move in the opposite direction of the longitudinal clamping, so that the profile is away from the first transverse positioning surface 230 and the first vertical positioning surface 240 of the cutting table 200, avoiding the profile from being scratched by the first transverse positioning surface 230 and the first vertical positioning surface 240 during feeding. When the profile is fed forward by a preset length, the transverse moving unit 490 drives the feeding table 400 to move in the direction of the transverse clamping, and the longitudinal moving unit 480 drives the feeding table 400 to move in the direction of the longitudinal clamping, so that the second vertical positioning surface 450 is flush with the first vertical positioning surface 240, and the second transverse positioning surface 440 is flush with the first transverse positioning surface 230. After that, the clamp of the feeding table 400 releases the clamping of the profile, the first transverse clamp 260 of the feeding cutting table 210 and the discharging cutting table 220 drives the profile to move in the direction of the first vertical positioning surface 240, and then the first longitudinal clamp 250 of the feeding cutting table 210 and the discharging cutting table 220 presses the profile downward on the first transverse positioning surface 230, and then the cutting device 300 drives the cutting knife 310 to cut the profile in the left-right direction. During the slitting, the feeding table 400 retreats to clamp other positions of the profile, and during the retreat of the feeding table 400, the transverse moving unit 490 drives the feeding table 400 to move in the direction of the transverse clamping, and the longitudinal moving unit 480 drives the feeding table 400 to move in the direction of the longitudinal clamping. Since the profile is clamped by the clamp of the cutting table 200 at this time, the profile can be away from the second transverse positioning surface 440 and the second vertical positioning surface 450 of the feeding table 400, so as to avoid the feeding table 400 from being scratched by the profile during the retreat. When the feeding table 400 retreats to a predetermined distance, the transverse moving unit 490 drives the feeding table 400 to move in the opposite direction of the transverse clamping, and the longitudinal moving unit 480 drives the feeding table 400 to move in the opposite direction of the longitudinal clamping, so that the second vertical positioning surface 450 is flush with the first vertical positioning surface 240 again, and the second transverse positioning surface 440 is flush with the first transverse positioning surface 230 again, for positioning and clamping the profile. Compared with the prior art, the profile can be prevented from being scratched during slitting, which is beneficial to maintaining the smoothness of the cutting piece and improving the cutting precision of the cutting piece.

[0046] In some embodiments of the utility model, in order to adapt to different sizes of section bar, the left and right positions of the first horizontal clamp 260 and the second horizontal clamp 470 are adjustable, and the adjustment mode is manual. When it is needed to slit large size section bar, the staff manually enlarges the distance between the first horizontal clamp 260 and the first vertical positioning surface 240 and the second horizontal clamp 470 and the second vertical positioning surface 450, and then locks the positions of the first horizontal clamp 260 and the second horizontal clamp 470 through the locking handle 471. When it is needed to slit small size section bar, the staff manually shortens the distance between the first horizontal clamp 260 and the first vertical positioning surface 240 and the second horizontal clamp 470 and the second vertical positioning surface 450, and then locks the positions of the first horizontal clamp 260 and the second horizontal clamp 470 through the locking handle 471.

[0047] It can be understood that the left and right positions of the first horizontal clamp 260 and the second horizontal clamp 470 can also be adjusted through an electric control mode, and are not limited to the above-mentioned embodiments.

[0048] The cutting member according to the second aspect embodiment of the utility model comprises the cutting machine according to the first aspect embodiment of the utility model. Since the cutting member adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0049] The utility model embodiments are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled in the art without departing from the purpose of the utility model.
