Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of non - metal welding auxiliary tools, in particular to a planing and cutting device for polyethylene welding flanges. Background Art
[0002] The commonly used and industry - recognized welding method with the highest welding strength for polyethylene plates and pipes is butt fusion welding (or "butt welding"). The specific construction process is as follows: Use a heating plate to heat the welding end faces of two workpieces to the melting temperature, remove the heating plate, and quickly butt - joint and press the two melted end faces together; during this process, due to the extrusion effect, at the welding joint, the melted material will bulge outwards and form a flange. Since the existence of this flange may cause potential hazards such as stress concentration, it is necessary to use tools to cut off this flange.
[0003] Currently, the flange is usually removed by manually holding a hammer and hitting a flat chisel. The disadvantages of this method are: first, low efficiency; second, poor accuracy, and it is easy to occur the phenomenon of incomplete removal or damage to the workpiece. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a handheld planing and cutting device for polyethylene welding flanges.
[0005] To solve the above - mentioned technical problems, the technical solution provided by the utility model is as follows:
[0006] A planing and cutting device for polyethylene welding flanges includes an inverted buckle groove, a tool holder, a tool holder fixing bolt, an angle adjusting bolt, and a pulling and fixing bolt;
[0007] The inverted buckle groove is an inverted groove - shaped structure, and through - hole one, through - hole two, and through - hole three are arranged on the top groove wall of the inverted buckle groove;
[0008] The tool holder includes a blade, a front open ring, and a rear open ring. The tool holder is located in the hollow cavity of the inverted buckle groove;
[0009] The blade is arranged at the bottom opening of the front open ring and at the bottom opening of the rear open ring, and the front open ring is located in front of the rear open ring;
[0010] The blade is arranged to tilt upwards in the front - to - rear direction. The front end of the blade is provided with a cutting edge for planing, and the rear part of the blade is provided with a blanking through - hole;
[0011] The top of the rear open ring is provided with a through - hole. The tool holder fixing bolt is inserted into through - hole one on the top groove wall of the inverted buckle groove and the through - hole on the rear open ring to form a bolt connection, so as to fix the tool holder in the inverted buckle groove through the bolt connection;
[0012] The nut of the angle adjustment bolt is welded and fixed on the outer length and width surfaces of the top groove wall of the inverted buckle groove. The angle adjustment bolt is sequentially inserted downward into the welded nut and into the second through hole on the top groove wall of the inverted buckle groove until the bottom end of the angle adjustment bolt presses against the top of the front opening ring, so as to screw the angle adjustment bolt to adjust the degree of pressing the front opening ring and further adjust the inclined cutting angle of the blade.
[0013] The pulling and fixing bolt is inserted into the third through hole on the top groove wall of the inverted buckle groove to form a bolt connection. The pulling and fixing bolt is used to connect with a pull rope or a pull rod to provide power to pull the planing cutter to move.
[0014] Preferably, the front opening ring is an arc-shaped opening ring, and the rear opening ring is a rectangular opening ring.
[0015] Preferably, the bottom opening of the front opening ring is welded and connected to the blade, and the bottom opening of the rear opening ring is welded and connected to the blade.
[0016] Preferably, on the top groove wall of the inverted buckle groove, the tool holder fixing bolt, the angle adjustment bolt, and the pulling and fixing bolt are arranged in sequence from back to front.
[0017] Preferably, both the inverted buckle groove and the tool holder are made of stainless steel.
[0018] The present application has achieved the following beneficial technical effects:
[0019] The working principle of the planing cutter is similar to that of a plane in woodworking tools. The planing cutter can closely fit the root of the flanging through an adjustable inclined blade, and then pull a pull rope or a pull rod fixed on the planing cutter along the length direction of the flanging (i.e., the length direction of the weld of two polyethylene plates, which is also the width direction of the polyethylene plate), so that the planing cutter moves along the length direction of the flanging. During the movement, due to the blade angle, the cut flanging provides a downward pressure, and the downward pressure forces the entire planing cutter to fit the surface of the polyethylene sheet, etc., achieving the effect of accurately cutting the flanging; the cutting effect of the flanging is excellent, the operation is convenient, and the flanging can be cut efficiently and with high quality.
