Description

Synthetic resin pipe cutting apparatus

The present invention relates to a synthetic resin pipe cutting device, and more particularly, when cutting as a cutting blade in a state in which a plurality of pipes are clamped on a cutting device, the upper surface pressing table pressing the upper portion of the pipe is cut while pressing multiple pipes at once. The cutting blade exposed to the upper part of the cover is covered, and the cutting blade that has been cut is retracted backward from the lowered state, and when cutting, the cutting blade is moved in the longitudinal direction while moving in the longitudinal direction to cut multiple pipes at once. , Chips generated in the process of cutting the pipes are sucked and collected from the blade cover box surrounding the cutting blades and discharged to a dust collector, so that a number of synthetic resin circular pipes are safely cut to the correct dimensions and synthetic resin chips scattered during the cutting process work. This is to prevent them from flying to the field.

In the prior art, the design of Utility Model Registration No. 20-0210562 (name of design: automatic loading device structure of wood cut by an automatic cutter) is known by the Registered Utility Model Publication.

Part of the conventional design compared to the present invention, the structure of the cutting blade for cutting wood is moved up and down by a cylinder, and covers the cutting blade exposed to the upper side of the blade groove formed in the blade guide plate to prevent a safety accident. This is a configuration in which the safety cover is lifted up and down by a cylinder.

When cutting wood in the conventional design, the safety cover is lowered by supporting the wood to be cut on the transfer guide plate on the upper surface of the blade guide plate to which the cutting blade will protrude, so that the lower part of the safety cover contacts the upper surface of the wood and the cutting blade Cover the portion to be projected.

In this state, when the operator drives the cutting blade in a state where the exposed wood on both sides of the safety cover does not move, the disc-shaped cutting blade rises while rotating in place and starts cutting the wood from the bottom to gradually cut the wood. It will be cut to the upper side.

When cutting wood like this, when the wood is cut from the bottom to the top, when cutting the wood, the rising cutting blade generates a load to lift the wood upwards, so that the worker does not lift the wood from the top to the bottom. You have to cut it while pressing it firmly.

In the process of cutting the wood as described above, if the worker cannot properly grasp the wood, the wood cannot be accurately cut while rotating, and the worker must hold the wood tightly for a long time so that the wood does not lift upward and does not turn. So there was a problem that the worker is easily exhausted.

In addition, assuming that a plurality of timbers are cut using a conventional design, it is difficult for an operator to hold a plurality of timbers so that their timbers do not move with a uniform force. Since it had to be cut (see FIG. 4B of the conventional draft), there was a problem that productivity was reduced.

And, in the process of cutting wood with a disk-shaped cutting blade, a chip hits the inner surface of the safety cover and then comes out as an open part under the safety cover, some of which are on the blade guide plate around the blade groove. Stacked, another part was scattered around the safety cover, which not only interferes with the cutting operation, but also has a problem that harms the health and safety of the worker.
