| Elbow machine manufacturer to the equipment specification analysis
The World Monetary Fund (IMF) said on Tuesday that our companies should hold structural and financial reforms to create a more stable and balanced economic growth model.
Speaking at the World Economic Outlook (WEO) press conference in Washington, Gian Maria Milici-Ferretti, Assistant Director of the Research Department of the International Monetary Fund (IMF), said: "It is extremely tight to hold financial sector innovations, social security innovations and monetary policy innovations that will ensure that the range of tools that governments have are fully modern and appropriate. To ensure stable and solid growth of elbow machines in the future."
Elbow machine drive spindle is directly inserted into the upper part of the head, accurate installation, easy maintenance, elbow spindle and drive sprocket overall casting, overall processing, overall rolling teeth, no key connection, average force, driven by two cylinders, during the elbow process, the rotary arm near the bending set Angle before the hydraulic system automatically save buffer, greatly improve the bending accuracy, fast reset, Returning the process closer to the start saves buffering, greatly improving reset accuracy and things efficiency. Full hydraulic drive. The microcomputer controller can be preset to 16 angles, and the whole process can be completed once by the foot switch of the elbow propulsion machine.
Elbow head and bed reinforcement design, annealing to eliminate internal stress, overall strength and stiffness enough to prevent deformation. The transmission spindle is directly inserted into the upper part of the machine head, accurate installation, easy maintenance, the bending spindle and the transmission sprocket integral casting, integral processing, integral rolling teeth, no key connection, force symmetry, driven by two cylinders, during the bending process, the hydraulic system automatically saves the buffer before the rotating arm is close to the bending set Angle, greatly improving the bending accuracy, fast reset, saving the buffer near the beginning. Greatly improve reset accuracy and efficiency. Under the full hydraulic drive, the microcomputer controller can be preset 16 angles, and the entire process can be completed at one time through the foot switch of the elbow propulsion machine, including hydraulic clamping, hydraulic material, hydraulic elbow, hydraulic core extraction, five cylinders (to increase the efficiency of car feeding and space corner).
The bending machine is made of seamless steel pipe, welded steel pipe or spiral pipe as raw material, accepting intermediate frequency heating, adjustable power and frequency, suitable permeable heat, stable performance of the product, intermediate frequency power factor above 0.95, energy saving, novel equipment, compact structure, automatic operation and high production efficiency. Accepting hydraulic cylinder to promote raw materials, strong thrust, stepless speed change, automatic control, can greatly save manpower and material resources, with low construction investment, high material rate, raw material specifications and other advantages.
How to solve the problem in the production of elbow pipe fittings: For the pipe fittings with serious flattening of the outer side of the arc, the compression die can be designed into the structural situation of the anti-deformation groove: select the appropriate mandrel (flexible mandrel that can accept multiple segments of mandrel assembly when necessary), install it correctly, and ensure that the pipe groove shaft of each component is on the same horizontal plane.
In small radius bending, the bending process characteristics determine the thinning of the outer arc, which can not be stopped. In order to stop excessive thinning, the commonly used useful key is to use a cold pushing elbow machine with a side pushing device or a tail pushing device to offset the departmental resistance of the pipeline bending by pushing or pushing, improve the stress diffusion state of the pipeline cross section, make the neutral layer move outward, and achieve the purpose of reducing the outer wall of the pipeline. For the outer arc bending of the pipeline, first ensure that the thermal treatment of the pipeline is in good condition, then check whether the compression die pressure is too large, the mediation pressure is appropriate, and finally ensure that the core and the pipe wall are well lubricated to reduce the bending resistance and the friction between the inner wall and the core. For in-arc wrinkling, corresponding measures should be taken according to the wrinkling position. If the front cut point is wrinkled, the position of the mandrel should be adjusted forward to reach the reasonable support of the pipe when the bend is reached: if the back cut point is wrinkled, the anti-wrinkle block should be installed to make the installation position of the anti-wrinkle block correct, and the mold pressure should be adjusted appropriately; If the arc is full of wrinkles, it means that the diameter of the mandrel used is too small, so that the gap between the mandrel and the pipe wall is too large, or the die pressure is too small, and the pipe can not fit the bending die and the wrinkle block well during the bending process. Therefore, the mandrel should be replaced and the decompression die adjusted to make the die force appropriate.
For the bending and returning signs, the compensation method and the correction method are mainly accepted to control. Compensation method is through the comprehensive analysis of the influencing factors of bending round trip, according to the various conditions of bending and round trip trend, the size of the round trip amount is estimated in advance, and the size and geometry of the convex and concave die departments are corrected in the design and manufacturing of the mold, so as to achieve "over-positive" bending. The correction method is to take measures on the mold structure to make the correction force concentrate at the corner, change the stress state, actively eliminate the elastic deformation, and surrender the round trip. For example, in the bending process, a tension is applied at the same time of bending, so that the entire section is under the action of tensile stress. During unloading, the elastic recovery is consistent with the deformation deviation, which can significantly reduce the rebound amount.
