Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

Referring to fig. 5 and 6, a plastic tube punching apparatus includes a fixing plate 3, a rotary support 4, and a blade assembly for punching plastic tubes and a blade 5 thereof. A motor reducer (not shown) for powering the perforating device for perforating plastic tubes is preferably mounted on the fixed plate 3. The power output gear 2 of the motor reducer is meshed with the slewing bearing 4 to transmit power. An axial through hole 32 for the plastic tube 8 to pass through is arranged on the fixing plate 3, a radial groove 31 is arranged on the side surface of the fixing plate 3, and the notch of the radial groove 31 is communicated with the axial through hole 32. The slewing bearing 4 is rotatably mounted at an axial through hole 32 of the fixed plate 3, the slewing bearing 4 being located upstream of the fixed plate 3 as seen in the direction of movement of the plastic tube 8. The radial slots 31 are preferably evenly distributed with six. A wave groove 41 is annularly arranged on the slewing bearing 4, and the wave groove 41 is preferably evenly distributed with six wave crests and six wave troughs. The blade assembly is preferably provided in six groups.

Referring to fig. 3, 4, 5 and 6, the blade assembly for perforating plastic tubes comprises a blade 5, a roller 6 is fixedly connected to the blade 5, and the blade 5 is fixedly connected to the roller 6 through a set screw 7. The blade assembly blade 5 is located in the radial slot 31 and the blade assembly roller 6 is located in the wave slot 41. In the rotating process of the slewing bearing 4, the wave crests and the wave troughs of the wave grooves 41 alternately pass through the rollers 6, and the blade assembly makes radial reciprocating motion in the radial grooves 31 of the fixing plate 3, so that the feeding and retracting actions are completed. When the roller 6 is positioned at the wave crest of the wave groove 41, the blade component is in a tool retracting state; when the roller 6 is located at the trough of the wave groove 41, the blade assembly is in the feed state. The blade 5 slides on the fixing plate 3 to form sliding friction, and the roller 6 rolls in the wave groove 41 to form rolling friction, so that the resistance is small.

As shown in fig. 3, 4, 5, 6, 7, and 8, the radial groove 31 includes a deep groove section 311 and a shallow groove section 312, and the shallow groove section 312 communicates with the axial through hole 32. When the blade component does radial reciprocating motion, the set screw 7 of the blade component radially reciprocates in the deep groove section 311, the blade 5 extends out of the shallow groove section 312 to punch the plastic pipe 8, the space of the shallow groove section 312 is small, so that the blade 5 is close to the bottom of the shallow groove section 312, the vibration generated by the blade 5 in the punching process can be reduced, and the service life of the blade 5 is prolonged.

As shown in conjunction with fig. 1 and 2, the blade 5 includes a mounting section 51 and a cutting edge section 52 that are coupled together. The mounting section 51 is provided with a mounting hole 511 to facilitate mounting of the blade 5. The end of the blade section 52 is provided with a crescent groove 522, the groove bottom of the crescent groove 522 is provided with a concave part 5222, the edge of the concave part 5222 forms a blade angle, and two sides of the notch of the crescent groove 522 are cut to form two sharp blade edges 5221; both side portions of the blade section 52 are provided with side blades 521. The blade 5 completes the punching action for a three-edge structure, and has the advantages of easy feeding and retracting, ensuring the strength of the blade 5, clean cutting, no residue of scraps dropped during punching on the plastic pipe 8 and the like.

As shown in fig. 1 and 6, the fixing plate 3 is fixedly mounted on the base plate 1.

When punching plastic tubing 8, can be according to actual need to using the utility model discloses a plastic tubing punches and carries out rational layout design with blade subassembly and blade 5's plastic tubing perforating device, radial groove 31 on the size and size of the shape of blade subassembly, the fixed plate 3 and the annular wave groove 41 isotructure on the slewing bearing 4. The plastic pipes 8 with different pipe diameters are punched by changing the length of the blades 5 in the clamping and conveying assembly for conveying the plastic pipes 8 and the blade assembly. The plastic pipe 8 can be a single-wall light pipe, a single-wall corrugated pipe or a double-wall corrugated pipe. The power device can select a motor adopting frequency conversion speed regulation, thereby achieving the purpose of regulating the punching frequency and speed.

Use the utility model discloses a plastic tubing punches and uses blade subassembly and blade 5's plastic tubing perforating device is particularly useful for punching to the plastic tubing 8 that the pipe diameter is less, the pipe wall is thinner.

The following detailed description of the process of punching the plastic pipe by using the plastic pipe punching device with the blade assembly and the blades of the blade assembly for punching the plastic pipe of the present invention is as follows:

as shown together with fig. 5, 6 and 9, the plastic tube 8 to be perforated is placed on a holding and conveying device for conveying the plastic tube 8. And starting the motor speed reducer, and simultaneously driving the clamping and conveying device and the plastic pipe punching device to work by the motor speed reducer. The centre gripping conveyor carries plastic tubing perforating device department with plastic tubing 8, and when perforating device's blade subassembly's gyro wheel 6 was located the trough of wave groove 41, perforating device punched plastic tubing 8, played plastic tube hole 81, because slewing bearing 4 ceaselessly rotates, after finishing punching, when perforating device's blade subassembly's gyro wheel 6 was located the crest of wave groove 41, the blade subassembly was accomplished and is moved back the sword. The plastic tube 8 continues to advance and the perforated plastic tube section moves to the other side of the holding plate 3. And repeating the above actions to continuously complete the punching operation of other pipe sections of the plastic pipe 8.

In the description of the present specification, it is to be understood that the terms "radial slot", "axial through hole", "slot bottom", "forward movement", and the like, are used in the orientations and positional relationships illustrated in the drawings, and are only used for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
