mechanical engineering knowledge

Q: What is the relationship between rivet length and riveting quality? A: guide pin, guide sleeve and guide plate. The rivet is too short, the piers are not large enough, the nail head is incomplete. Line heat forming is only suitable for parts with small curvature, and more is combined with rolling pressure to process parts with double curved complex shapes. The method of rectifying the line segment is as follows: rotation method, right triangle method, change surface method, branch line method. Water cooling is divided into front water cooling and back water cooling. A: It consists of the working part, the material locating part, the unloading part and the mold base. This is count on adjusting what? If the target of cutting is to make a certain appearance of the workpiece, that is, the blanking part of the need is called the blanking. Close seam: the edge of the two sheets or the two sides of a piece of plate are combined to squeeze each other, which is called a close seam. The shape of the heating zone is: dot, line and triangle. The ignition point of ordinary carbon steel in oxygen is: 1100-1150℃. Here’s a list of mechanical engineer skills for resumes, cover letters, job applications and interviews. Assembly: to combine the parts according to certain technical conditions. A: Mechanical properties of bent material, bending angle, bending direction of materials, surface quality of materials and shear section quality and some other factors. The structural features of composite blanking die are: the punch and die not only has the function of blanking, but also hole punch. Q: What are the characteristics of vibrating shears? Replies. In correcting the deformation of the sheet in the steel structure, it is necessary to ensure that all kinds of frames meet the requirements, and then we can consider the correction of the thin plate. Let’s make this complex question easier with following the real-life scenario to understand key mechanical engineer skills & roles of a mechanical engineer or mechanical engineering graduate – “If any machine is moving or using energy, Mechanical engineer … Angle connection: when the two plates are connected perpendicular to each other, they are riveted together with angle steel at the joint. Correction position: the position of the correction method for the deformation of steel structure, sometimes the correction part is not necessarily the deformation part of the component. The method of reducing blanking force is: inclined cutting, stepped terrace die cutting, blanking heating cutting. A: Too high will reduce the initial stress of the nail rod; too low, the rivet will generate the blue brittleness phenomenon. Internal force: when the object is deformed by external forces, a force of resistance that occurs within it is called internal force. Get an article everyday. Cloud Computing Project Ideas for students, 40 Important PLC Projects for Engineering Students, How to enable developer options in MIUI 8 & MIUI 9. Margin: the distance from the outside rivet center to the workpiece plate. Graduate knowledge of mechanical engineering is vital in the solving of challenges faced by industry and society alike. Q: What process is the welding process for the metal structure? Non-manual clamping include: pneumatic clamp, hydraulic clamp, magnetic clamp. It is powered by hand or compressed air and riveted by special tools. The main contents of lofting are: the plate thickness processing, the expansion of the drawing and to expand the drawing of the marking sample according to the made components. The principle of intersecting line choosing method is: a projection of the intersecting line at least one known intersecting line by the tessellation line method. Q: How to understand the inner connection of steel structure? Cold riveting: rivet in normal temperature condition is called cold riveting. Internal stress: when there is no external force, the internal stress is called internal stress. They might work with people who are not mechanical engineers, such as computer scientists or architects. Reply Delete. (5) there is no friction between the mandrel and the pipe wall, which reduces the torque of the bending tube, thus extending the service life of the pipe bender. Q: The way to find a line segment is the parallel line method, the triangle method and the radiation method, right? 4: when heating, the gas welding torch should not swing back and forth, the small flame should be a vertical steel plate, and the hot spot should not be too much, so as not to increase the internal stress. Please do leave your comments/requests/feedbacks in the section below, it really motivates us and keeps us going! Make sure you have at least one example of a time you demonstrated each of the top 5 skills listed here. (2) The intersecting line is always closed because the form has a certain range. Press bending: the process of using bending mold on a press machine to do bend forming. Heating correction is divided into: full heating correction and local heating correction. As a result, the drill bit is broken or the drilling quality is reduced. Water cooling: the metal that has been heated partly by the use of water to cool it quickly, reduces the heat transfer to the back, enlarges the temperature difference between the front and the back, and improves the molding effect. These parts are interconnected and mutually restricted to form organic integrity. The cross-section of the section graphics is the same when cut the cylindrical surface with a parallel plane.
