For some enterprises engaged in small batch cutting and stamping of sheet metal parts, in order to ensure the quality of the products, the surface and corners of these workpieces must be polished and deburred, but deburring has become a problem: if the processing is done, because of the batch Small, some professional processors are not happy, and the quality and delivery time are also difficult to guarantee; to solve it yourself, you need to purchase a set of equipment, the investment is large, and it is not worthwhile. Therefore, the deburring of these workpieces has to be done manually, using a sanding tool. But the effect of deburring is not ideal.
Deburring field Deburring, polishing, chamfering automation, more than a dozen models offer a choice to find a more perfect solution. The passivation deburring machine is specially designed for batch deburring equipment for cutting and stamping parts. It uses several passivation (special brush) under each host to rotate at high speed. The abrasive slides over the edge of the product and all corners pass through the universal high speed. Rubbing burrs. At the same time, the replacement is performed to make the chamfering and deburring uniform, and the processing is automatically completed while conveying the product through the straight line or the disc.
1. Suitable for laser cutting, CNC, ordinary punching, die-casting, wire drawing, metal burrs after grinding, flanging, cutting sharp edges.
2. For irregular parts, all the irregularities in the hole, including the dead angle of the slit, can be uniformly deburred and evenly chamfered.
3. Uniform removal of the same plane burr, any external size hole hole burr and even chamfering, high-end quality that can not be replaced by manual and other equipment
4. Planar and special-shaped sheet metal laser cutting all-round deburring, all-round uniform chamfering
A lot of electromechanical equipment and daily necessities have to use radiators, such as notebooks, car radiators, etc., its importance is also very important, Imagine your notebook has been running for a long time on a hot summer day, if there is no radiator What is the hot temperature? If the temperature is too high, it will not only affect the normal operation but also shorten the service life.
Products such as heat sinks will have burrs in the groove after milling the plane. Now if the manual deburring / manual deburring every time, it is a waste of too much labor and man-hours. The burrs in the product slots such as heat sinks may sometimes cause employees to cry without tears---big burrs are time-consuming and laborious, and small burrs are not easy to remove!
Magnetic deburring machine, clever magnetic field distribution, conducting fine grinding of stainless steel needles, generating high-speed flow, turning heads and other actions, in the workpiece hole, surface friction, polishing, cleaning, removing burrs and other precision grinding effects can be 5-10 minutes During the time, the fins and the corner burrs are quickly processed very well. The main purpose is to achieve deburring and polishing by tumbling the fine polishing needles against the surface and corners of the product.
In various processes, the excess portion derived from the machined part that does not conform to the required shape and size is a burr. The production of burrs varies with the processing method. According to the different processing methods, the burrs can be roughly divided into:
Cast burr: Excess material produced at the joint of the mold or at the root of the gate. The size of the burr is generally expressed in millimeters.
Forged burr: at the joint of the metal mold, due to the plastic deformation of the forging material. Electric welding, gas welding burr: welding burr, is the filler at the weld protruding from the surface of the burr on the part; gas welding burr, is the slag overflowing from the slit when the gas cuts.
Stamping burr: When punching, there is a gap between the punch on the die and the die, or there is a gap between the cutters at the slit, and burrs are caused by the wear of the die. The shape of the punch burr varies depending on the material of the plate, the thickness of the plate, the gap between the upper and lower dies, the shape of the stamped part, and the like.
Machining burrs: machining methods such as turning, milling, planing, grinding, drilling, and reaming can also produce burrs. The burrs produced by various processing methods vary in shape depending on the tool and process parameters. Plastic forming burrs: As with casting burrs, burrs are produced at the joints of plastic molds.
Due to the presence of burrs, the entire mechanical system will not work properly, resulting in reduced reliability and stability. When a machine with burrs is mechanically moved or vibrated, the burrs that are detached may cause premature wear and noise of the sliding surface of the machine, and even cause the mechanism to become stuck and malfunction. Some electrical systems may be burred when moving with the main engine. If the system is short-circuited or the magnetic field is damaged, it will affect the normal operation of the system. For hydraulic system components, if the burr falls off, the burr will exist in the tiny working gap of each hydraulic component, causing the spool to become stuck and the circuit or filter to be blocked. The accident can also cause fluid turbulence or laminar flow, reducing the performance of the system. Japanese hydraulic experts believe that 70% of the causes affecting the performance and life of hydraulic components are caused by burrs; for transformers, the core with burrs increases the iron loss of iron core by 20 to 90%, and increases with frequency. . The existence of burrs also affects the assembly quality of the mechanical system, affects the processing quality of the subsequent processing steps of the parts and the accuracy of the test results
