Numerical control equipment replaces ordinary equipment position

Milling head, which is installed on the milling machine and connected to the main shaft, is used to drive the milling cutter rotation machine tool attachment. It is the main component of machine tool equipment.

According to the different milling cutting direction, milling head can be divided into vertical milling, transverse milling, horizontal milling, reverse horizontal milling, etc.

Ordinary machine tool can be divided into milling machine, lathe and drilling machine. These equipments through the technical worker operating the hand wheel moving knife rest make the cutter along the right direction to the part processed by position. Among them, the milling machine refers to mainly use milling cutter in the work piece processing all kinds of surfaces’ machine tools. It can processing flat, grooved, various surface, gear, etc., are widely used in machinery manufacturing and repair department.

But relatively speaking, ordinary equipment processing efficiency is lower, cost is higher. Therefore, numerical control equipment has gradually or completely replaces ordinary equipment in many fields, different from ordinary machine tool, numerical control machine tool processing part processes fully automatically proceed, and worker cannot intervene in the processing course.

Such as numerical control milling machine for drilling, boring, thread tapping, contour milling, milling plane, plane cavity milling and space three-dimensional complicated surface milling. Machining centre, flexible manufacturing cell is being and developing on the basis of the numerical control milling machine, the main processing method is also milling processing way.

And according to the classification of ordinary milling machine, numerical control milling machine can be divided into numerical control vertical milling machine, the spindle axis perpendicular to the horizontal plane, the most widely application scope; Horizontal numerical control milling machine, the spindle axis parallel to the horizontal plane; Vertical horizontal dual conversion milling machine, the spindle can transform, can be in the same numerical control milling machine for vertical and horizontal machining, with a vertical, horizontal numerical control milling bed function.

Role of different materials buffers in crane

Abstract: Crane buffers is an important safety protection device of a crane, the protective effect of buffer itself, service life and other technical parameters can directly influence the crane safe operation. Commonly used buffer have the rubber type, polyurethane type, spring type, hydraulic type, and other institutions, each have advantages and disadvantages.

Crane buffer in the hoisting machinery equipment, which belongs to a safety protective device, is installed in orbit on the device security components. Buffer function is the equipment in the running process, absorbs the impact force produced by the impact, so as to effectively protect and mitigate the impact caused by equipment damage. Therefore the buffer manufacture and use have strict regulations and restrictions.

First, Entity buffer

1, Rubber buffer: the buffer structure is simple, but it can absorb less energy and is commonly used in crane running speed is not more than 50 / min, major played a blocking role.

2, Polyurethane buffer: polyurethane foam cushion absorbed energy, good buffer performance, oil resistance, aging resistance, acid resistance, corrosion resistance, high temperature and low temperature resistance, insulation, explosion-proof, relative density and pediatrics is light, simple structure, low price, no noise, no spark, easy installation and maintenance, long service life, etc. Therefore, the international community has widely adopted, on the general crane, can replace rubber and spring buffer, at the explosion sites more worthy of promotion.

Second, Spring buffer

Spring buffer is mainly by the meet, springs and shell composition. Its characteristics are relatively simple mechanism to use reliable. When the crane hit the spring buffering, its energy is converted into a compressed energy of spring. Improved with check spring institutions spring buffers, can prevent a rebound.

Third, Hydraulic buffer

When buffer by collision, kinetic energy after the plug head and accelerate the spring to the piston, the movement to the right. The original buffer work chamber is equipped with a reset spring, plunger, and the oil. Piston movement extrusion working chamber of the oil, make its reset spring compression, while making the oil from the annular space between the piston and the plunger extrusion, into the oil storage chamber. At the beginning of the piston movement, due to large and annular space between the push rod, the oil is easy to be squeeze out; In the piston continues to exercise, the annular space are getting smaller and smaller, the piston resistance increasing, to stem the cylindrical phase, annular clearance for difficult can tell, the resistance is also stable in maximum. Buffer is compressed is through the process of squeezing oil piston the process of doing work. The process consumes a large amount of kinetic energy, play a buffer role. When work is finished, the piston return spring is pushed to the original location, to complete a working cycle.

Tapping the power head three processing methods is introduced

Abstract: In the automation processing, drilling and tapping is important, how to choose the most suitable for their use of tapping head for customers is critical. Because the tapping head processing way and drilling is different, there are three processing methods can achieve.

In automated processing, drilling and tapping are important, how to choose the most suitable for their use of tapping head is critical for the customer, the following PURROS according to the three kinds of tapping head on market power head way for an inductive summary analysis.

Tapping head processing way and drilling is different. First to choose the correct specification of the screw type (tool), and the rotation of the spindle must match the appropriate feed, to produce screw trajectory. There are three ways to achieve this cooperation:

1. A pair of gears, a connecting axis of rotation, a connecting feed shaft. So forward tool rotation and can be a thread.

2. The end of the spindle links a tooth gauge. Tooth gauge in the nut, forward backward. Because a nut fixed in power head main body, does not rotate. So as the gauge rotates, it will drive the main shaft, according to the tooth grain trajectory rotate forward.

3. Servo tapping: Don’t need to use the gauge. Motor control system, spindle speed and feed speed, makes the spindle rotation forward from screw trajectory.

Currently, use of tapping head on the market Are generally according to the Enter Method of power head is divided into four kinds: Guide screw tapping head, tapping head sample gauge type, gear type tapping head and Servo tapping power head. Among them, guide screw tapping head is the most simple and lowest cost, but also effect the worst, is the easiest to maintain a power head, currently on the market has been eliminated slowly. Gear type tapping head is usually assembled vertical only by tapping machine, servo tapping head effect is best, the efficiency is high, need to configure the servo motor drive.
