The cutter and the cutting device provided by the embodiment of the utility model are described.
Example 1:
based on the illustration in fig. 1, the present embodiment provides a cutter, which includes a first cutter body 1, and two sides of the first cutter body 1 are a first side edge 101 and a second side edge 102 respectively. The bottom of the first cutter body 1 is provided with a first cutting part 103 which extends out of the side of the first side edge 101, the bottom edge of the first cutting part 103 is provided with a cutting edge 104, and the bottom side close to the second side edge 102 is provided with a first cutting edge 105. When the first cutter body 1 falls down, the cutting edge 104 cuts the carcass. Subsequently, the first blade body 1 is laterally moved to cut the carcass by the first cutting edge 105. On the basis of the first cutter body 1, a second cutter body 2 is also matched with the first cutter body. When in use, the second cutter body 2 and the first cutter body 1 are positioned on the same plane, and the second cutter body 2 is arranged on the first side edge 101 in parallel. The bottom end of the second cutter body 2 is provided with a second cutting portion 201 which is shielded from the top end of the first cutting portion 103, and the second cutting portion 201 has a second cutting edge 202 which is provided opposite to the first cutting edge 105.
In use, the first cutter body 1 is dropped first, its cutting edge 104 cuts the carcass into a gap, and then the second cutter body 2 is dropped. Alternatively, the first cutter body 1 and the second cutter body 2 are simultaneously dropped, and the first cutter body 1 is preferentially contacted with the carcass, so that the cutting edge 104 of the first cutter body 1 also cuts the notch. The second cutting portion 201 is located at the top of the first cutting portion 103, and when the second cutter body 2 falls, the second cutting portion 201 can accurately fall into the notch. Even if the second cutter body 2 is slightly misplaced with the first cutter body 1, the second cutter body can slide into the notch under the concave deformation action of the notch edge, so that the first cutter body 1 and the second cutter body 2 are prevented from cutting the unconnected notch. Finally, the first cutter body 1 and the second cutter body 2 move back, and the first cutting edge 105 and the second cutting edge 202 cut the carcass to both sides to completely cut the carcass. The cutter effectively reduces the subsequent manual cutting repair operation which is increased due to the fact that the tire body cannot be completely cut, and improves the production efficiency of equipment.
Preferably, the thickness of the second cutter body 2 is smaller than the thickness of the first cutter body 1. Because the thickness of the first cutter body 1 is thicker, the first cutter body can prop open the carcass left and right to form a relatively larger gap, so that the second cutter body 2 is easier to be pricked into the carcass, and the cutting accuracy is further improved. In practice, the preferred thickness dimension of the first blade body 1 is 3 mm and the preferred thickness dimension of the second blade body 2 is 1.5 mm. In other embodiments, the thickness of the first blade body 1 may be selected to be 2.5mm, 3.5mm, or any size between 2.5mm and 3.5 mm. The thickness of the second blade body 2 may also be chosen to be 1mm, 2mm or any size between 1mm and 2mm.
Preferably, both the first cutting edge 105 and the second cutting edge 202 are concave in shape to prevent the carcass from sliding longitudinally off the first cutting edge 105 and the second cutting edge 202 during cutting.
Preferably, the cutting edge 104 is connected to the first cutting edge 105, so as to increase the overall length of the cutting edge of the first cutter body 1 as much as possible, thereby ensuring the cutting effect.
Further, the top side walls of the first cutter body 1 and the second cutter body 2 are provided with connecting holes 106 for external connection. The connection hole 106 is used for penetrating a bolt. The first cutter body 1 and the second cutter body 2 are connected with a cutter frame 304 of the cutting device through a bolt connection mode. The first cutter body 1 and the second cutter body 2 can cut the tyre body under the drive of the cutting device.
Example 2:
this embodiment provides a cutting device using the cutter shown in embodiment 1. Based on the illustration of fig. 1 and 2, the cutting device comprises a frame 301 and a carrying table 302 for carrying the carcass. The frame 301 is provided with a horizontal sliding rail 303, and two knife holders 304 are slidably arranged on the horizontal sliding rail 303, and the first knife body 1 and the second knife body 2 are respectively installed on the two knife holders 304. The carrying platform 302 is located at the bottom of the two tool holders 304, and the frame 301 is provided with a driving device 305 connected to the two tool holders 304. The driving device 305 is used for driving the two tool holders 304 to slide along the horizontal slide rail 303.
When in use, the two knife holders 304 are positioned in the middle of the horizontal slide rail 303 by default, the second cutting part 201 of the second knife body 2 is shielded from the first cutting part 103 of the first knife body 1, and the carcass to be cut is laid on the bearing table 302. When cutting, the two knife holders 304 drive the first knife body 1 and the second knife body 2 to drop respectively, or drive the first knife body 1 and the second knife body 2 to drop simultaneously. The cutting edge 104 of the first cutter body 1 cuts a notch on the carcass, and the second cutter body 2 extends into the notch in a proper manner. Subsequently, the two blade holders 304 slide back along the horizontal slide rail 303, and the first cutting edge 105 and the second cutting edge 202 cut the carcass to both sides to completely cut the carcass. Since the second cutting portion 201 is blocked by the first cutting portion 103, the second cutting portion 201 can precisely fall into the notch cut by the cutting edge 104. Even if the second cutter body 2 is slightly misplaced with the first cutter body 1, the second cutter body can slide into the notch under the concave deformation action of the notch edge, so that the first cutter body 1 and the second cutter body 2 are prevented from cutting the unconnected notch.
In this embodiment, the frame 301, the carrying platform 302, the horizontal sliding rail 303, the tool rest 304 and the driving device 305 all adopt corresponding devices in the existing cutting device, only the cutting tool on the existing cutting device is replaced by the first cutting tool and the second cutting tool, and the specific connection mode and the control mode are all in the prior art and are not repeated.
It should be noted that in embodiment 1 and embodiment 2, the falling of the first blade body 1 and the second blade body 2 does not represent the direct movement patterns of the two, but the movement patterns of the two with respect to the carcass. Specifically, two cases are included:
case one: the height of the tyre body is unchanged, and the first cutter body 1 and the second cutter body 2 move downwards. A lifting cylinder can be arranged on the tool rest 304, and the lifting cylinder drives the first tool body 1 and the second tool body 2 to vertically move.
And a second case: the heights of the first cutter body 1 and the second cutter body 2 are unchanged, and the carcass moves upwards. Lifting devices such as lifting cylinders can be arranged on the bearing platform 302, and the lifting devices drive the bearing platform 302 to vertically move.
The two conditions are the operation modes of the existing cutting device, and are not repeated.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
