Brick molding equipment design and operation


Increase the diameter of the spindle rotation to eliminate the phenomenon of bending down. Over the past few brick spiral axis of the cantilever part (ie part of a spiral) longer than the supporting part in the production process, moving frequently flex and swing, not only serious wear tailstock copper tile, and often produced by cylinder, thus making a spiral with the mud cylinder gap size can not be guaranteed. If the spindle bearing part of the extension, to more than 1 times greater than the cantilever part to ensure that the cantilever part of the stability in the production process, not only to overcome the friction cylinder phenomena, but also improves the life of copper tile tailstock (the original 2 3 months to 1 to 2 years). Increase the small gear shaft, the driven gear pressure fender modulus increase, etc., can prevent accidents, increase production. 3 extrusion operation essentials hollow brick molding operation for more stringent requirements, preparation and operation in the production process if the slightest negligence will bring many difficulties to forming. Therefore, in the molding operation should particularly note the following points: (1) port installed in the machine core head, should be considered the first appearance of the core shape and material properties, etc. take different forms, or out, or indentation machine port 3 -5ram, to avoid molding clay caused by pin holes after the first deformation. (2) Installation of the mold must be made machine mouth and nose with the three core centerline and the centerline of the screw shaft is, or will result in the Black Point section blank, bending and other ills. (3) The first test when fitted with the new mold,[link widoczny dla zalogowanych], extrusion billet bar some defects are often required to make an appropriate adjustment, as appropriate, to ensure stable production. (4) the use of more smaller core rod with the production of hollow core slabs, billets should be used to advance the core head and mouth to fill the gap between, fixed head position to the core in order to avoid bias occurs when the tilt out of stock. Core head position can be fixed by other methods, such as the head according to the number of cores, the bulk of the core head and core size and core rod in the fixed head standard distance, the ink on a drawing board holes, and then this piece of wood board from the machine before the mouth of the mouth of the core frame of the core set of people at the head end. With the mud extrusion, wood goes forward step by step, until the machine off the port end of the board automatically exposed, so you can play the role of head of fixed core. (5) always check the travel speed is uniform section blank. Inspection, investigation can be used \30 ~ 50mm) for a period of \This thickening when the inevitable brick ribs, short out some of the slower clay, brick ribs during the inevitable thinning, severe may fracture. Generally speaking,[link widoczny dla zalogowanych], should be required \phenomenon. The production of the core can be adjusted to control the head speed of constant speed blank. For the fast part of the material, which can be adjusted around the core head slightly inward (or in the core set of the first end of a nut, or adding a washer) to properly increase this part of the resistance,[link widoczny dla zalogowanych], to reduce the amount of this part into the mud . To make the corners of the mud faster, you can be near the outside corners of the core head slightly adjusted to reduce this part of the resistance due to increase the amount of mud into the corners. If the first method by adjusting the core is still not fully address the speed of the material, the mouth should be in the machine and the core structure and the installation of a search problem,[link widoczny dla zalogowanych], try to solve. (6) test of the blank can be properly softer. When a blank into the core after the machine is turned on the tap lubrication port, forming a good article to be blank, adjust the blank forming water until soft and hard right until the section blank. (7) If the stock squeeze past, or in part, very few take the mud, should stop to check the reasons to avoid damage to equipment. ( of section blank quality should be checked regularly, identify problems promptly corrected, in particular, to prevent deflection and the next hole collapse, and the bottom of the deformation phenomenon. (9) die wear, timely replacement of the core head and the machine port, to ensure that the brick porosity and size of the error does not exceed the standard requirements. (1O) extruder outage and if the stop operation of the time interval is longer, should remove the machine port, remove one of the remaining mud and washed with water to prevent drying and hardening mud port card crash.
