Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a chip-free cutting machine for wire mesh pipes. Background Art

[0002] Wire mesh skeleton pipe, referred to as wire mesh pipe, is a new type of improved steel skeleton plastic composite pipe. This new type of pipe is made of high-strength plasticized wire mesh skeleton and thermoplastic polyethylene as raw materials, and the wire winding mesh is used as the skeleton reinforcement of the polyethylene plastic pipe. The high-performance HDPE modified adhesive resin is used to tightly connect the steel wire skeleton with the inner and outer layers of high-density high-performance polyethylene, so that it has an excellent composite effect. Because the high-strength steel wire reinforcement is coated in continuous thermoplastic plastic, this composite pipe overcomes the shortcomings of steel pipes and plastic pipes, while maintaining their respective advantages.

[0003] In the process of cutting wire mesh skeleton pipes, due to the presence of steel wire, the saw blade of the cutting machine is worn out very quickly, and the unit price is high, which invisibly increases the production and manufacturing costs of the enterprise; and after cutting with the saw blade, the product port is uneven and tilted, resulting in frequent poor sealing problems. At the same time, saw blade cutting also has the problem of a lot of powder and difficulty in cleaning, which causes the product to stick after sealing, affecting the strength and appearance quality of the seal.

[0004] In addition, with the improvement of the level of automated production, after the automatic sealing of the equipment is promoted, the automatic sealing quality of the product is difficult to control due to the above factors, and unmanned production is not truly realized.

[0005] Therefore, designing a wire mesh pipe chipless cutting machine will cut the wire mesh pipe without chips, keep the workshop clean, realize unmanned automated production, and reduce labor costs, which will become the direction of further improvement. Utility Model Content

[0049] The workflow of the utility model is:

[0050] Replace the upper Havers block 26 and the lower Havers block 27 of the corresponding diameter on the sizing fixture 7 according to the outer diameter of the production specification, adjust the outer diameter pointer 42 and the wall thickness pointer 38 to the corresponding scales according to the required production specifications and wall thickness, and adjust the handle 50 to a suitable height of the stinger 49, so that the center of the wire mesh pipe to be cut is roughly in a straight line with the center of the reducing fixture 11; set the corresponding specification parameters to be cut in the background, such as: pipe diameter, wall thickness, cutting length, etc.;

[0051] Start the machine. When the length of the wire mesh tube reaches the set cutting length, the variable-diameter clamp 11 and the fixed-diameter clamp 7 clamp the pipe under the action of the material pressing cylinder 18 and the fixed-diameter cylinder 22 respectively. The moving cutting mechanism 3 moves along with the wire mesh tube. The revolution motor 48 and the reduction motor 33 are started. The revolution motor 48 drives the feed mechanism 8 to rotate rapidly, so that the cutting blade 64 rotates along the outer diameter of the pipe for cutting. The movement of the reduction motor 33 gradually deepens the cutting depth until complete cutting. When the cutting depth of the cutting blade 64 reaches the scale pointed by the wall thickness pointer 38, the front end of the blade induction plate 35 will be sensed by the limit sensor 37. The reduction motor 33 reverses and makes the cutting blade 64 return to the initial position. The rear end of the blade induction plate 35 is then sensed by the limit sensor 37, and the reduction motor 33 stops working. The revolution motor 48 stops working. At the same time, the variable-diameter clamp 11 and the fixed-diameter clamp 7 return to release the wire mesh tube. At the same time, the reset cylinder 59 acts to push the moving cutting mechanism 3 to reset through the push ring 60;

[0052] When the variable-diameter clamp 11 and the fixed-diameter clamp 7 start to clamp the pipe, the variable-diameter clamp 11 and the fixed-diameter clamp 7 drive the moving body to move forward together with the pipe. When the cutting is completed, both the variable-diameter clamp 11 and the fixed-diameter clamp 7 are released, and the moving cutting mechanism 3 stops moving forward. The reset cylinder 59 pushes the moving cutting mechanism 3 to reset through the push ring 60, and works in this way repeatedly.

[0053] It should be explained that the linear guides, motors, sensors, cylinders, etc. used in the present invention are all common models that can be purchased on the market. The industrial control computer can be used in the background to control the sliding distance of the linear guide, the extension or retraction of each cylinder, the induction of each sensor, and the operation of the cylinder respectively. The control connection methods involved are also easily achievable by those skilled in the art in the prior art, belonging to the conventional automatic control in the prior art and not the innovation point of the present invention. Therefore, the specific control connection methods are not marked in the figure and are not described in detail.

[0054] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, the modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
