What are the uses of the cattle head planer What is its working principle 5

The cattle head planer is suitable for small and medium-sized parts with a length of up to 1000 mm.

Although the bull head planer is easy to adjust, because it is a single-edge cutting, and the cutting speed is low, it does not work on the return trip, so the production efficiency is low, and it is suitable for single-piece small batch production.

The main motion principle of the bull head planer is the crank rocker mechanism, which converts the rotary motion into a linear reciprocating motion, the ram is the main motion, and the workbench is the feed motion.

Features of the bull head planer.

1. The workbench of the bull head planer can rotate left and right, and the workbench has a rapid moving mechanism of transverse and lifting; It is used to plane inclined planes, thus expanding the range of use.

2. The feed system of the planer adopts cam mechanism, which has 10 levels of feed. It is also very convenient to change the amount of passes.

3. The bull head planer is equipped with an overload safety mechanism in the knife passing system, when the operation is careless or affected by external force and cutting overload, the knife slips by itself, and the machine parts are not damaged to ensure the normal operation of the machine tool.

4. Between the ram and the bed guide rail, as well as the gear with speed and the main sliding guide rail surface, there is lubricating oil from the oil pump for lubrication.

1. The bull head planer is mainly used for planing the plane, forming surface and groove on the small and medium-sized workpiece in the production of a single piece and a small batch. Most of the main operations of small and medium-sized bullhead planers are driven by crank rocker mechanism, so the moving speed of the ram is uneven. Large cattle head planers generally use hydraulic transmission, and rams are basically average bookstores.

The ram carries a planer knife and runs in a straight line to and fro, and the return stroke speed of the ram is greater than the working stroke speed because the knife holder at the front end of the ram resembles a bull's head.

2. Due to the use of a single-edged planer to work, and no cutting when the ram returns, the productivity of the bull head planer is low. The main part of the machine is the maximum length of planing. The turret can be rotated at an angle in the vertical plane and can be fed manually, and the table can be carried with the workpiece.

Intermittent lateral or vertical feed operation. A planer that utilizes a knife cutting machine that moves back and forth to process smaller workpieces on an object fixed on a machine tool working platform).

The prime mover part is the motor.

The transmission part is a gear, crankshaft connecting rod mechanism.

The executive part is the ram.

The control part includes the working part, the clutch handle, the shift control handle.

Linear motion machines that plane the plane, groove or formed surface of a workpiece with a planer. With planers, the tools are simpler but less productive (except for long, narrow planes), so they are mainly used for single parts, small batches and machine shops, and are often replaced by milling machines in high-volume production. According to the structure and performance, planers are mainly divided into bull head planers, gantry planers, single-arm planers and specialized planers (such as planers for planing the edge of large steel plates, planing punches and planers for complex shape workpieces).

The bullhead planer is named because the ram and the knife holder resemble the bull's head, and the planer knife is mounted on the ram knife holder for longitudinal reciprocating motion, and is mostly used for cutting various planes and grooves. The gantry planer is named because there is a gantry frame structure composed of top beams and columns, and the workbench carries the workpiece through the gantry frame for linear reciprocating motion, which is mostly used for machining large planes (especially long and narrow planes), and is also used to process grooves or planes of several small and medium-sized parts at the same time. Large gantry planers are often equipped with components such as milling heads and grinding heads, so that the workpiece can be planed, milled and ground after a single installation.

The single-arm planer has a single column and a cantilever, and the workbench makes longitudinal reciprocating motion along the bed guide rail, which is mostly used for processing workpieces with large widths and no need to process the entire width.

The reciprocating linear motion is made by the tool or the workpiece, and the intermittent feed motion perpendicular to the main motion is made by the workpiece and the tool. Commonly used planers are: bull head planers, gantry planers and single-arm planers.

Planing is mainly used for machining various planes (horizontal, vertical and beveled).

Various grooves (straight grooves, T-grooves, dovetail grooves, etc.) and forming surfaces, etc.! As shown in the figure below:

The maximum cutting length of the cattle planer is generally not more than 1000 mm, which is suitable for machining small and medium-sized parts.

The bull planer cannot process shafts, discs, rings and hole parts, etc.!

It can plane horizontal planes, T-grooves, vertical planes, and inclined planes, but cannot process arcs.

The principle of the planer application is to convert the rotary motion of the motor into linear motion, so a conversion mechanism should be connected. The pendulum is part of this mechanism, with a disc and a motor attached at one end and a linear guide rail at the other.

This converts rotational motion into linear motion to work.

The return force is small, the acceleration is fast, and the production efficiency is improved. The process is slow, the thrust is large, it is conducive to planing, and the motor works more smoothly.
