Programming example processing contour, where point O is the starting point, the path can be from OA-AB-BC-CD-DE-EF-FA-AO, or from OA-AF-FE-ED-DC-CB-BA - AO, according to OA-AB-BC-CD-DE-EF-FA-AO route programming as follows: Previous page A two-wheel type is more stable on level ground, while the almost
universal one-wheel type has better maneuverability in small spaces, on
planks or when tilted ground would throw the load off balance. The use
of one wheel also permits greater control of the deposition of the load

construction industry and in gardening. Typical capacity is
approximately 45-120 litres (4-9 cubic feet) of material. wheelbarrow Wheel Barrow, Steel Wheelbarrow, Wooden Handle Wheelbarrow, Kids Wheelbarrow, Heavy Duty Wheelbarrow, Power Wheelbarrow QINGDAO HYTANG HAND TRUCK CO.,LTD. , http://www.cnwheelbarrow.com

Ask the students to think about how to program along the OA-AF-FE-ED-DC-CB-BA-AO route.
2. In order to input the information and processing route in the drawing into the computer, automatic programming is expressed by a certain automatic programming language (CNC language) to constitute the source program. After the source program is input, the necessary processing and calculation work is performed by the application software (compiler for the CNC language). The processing program of our numerical control programming language here is mainly divided into three parts: (1) direct processing of input code; (2) conversion of drawing into code processing;
(3) Scan graphics are converted to code processing.
Automatic programming is based on the input of programming information and the way the computer processes information. It is divided into an automatic programming method based on automatic programming language and an automatic programming method based on computer drawing. Language-based automatic programming method. During programming, the programmer expresses the entire contents of the processing in the form of language according to the programming manual and part pattern of the numerical control language used, and then inputs the content into the computer for processing. An NC machining program that can be directly used for CNC machine tools. Based on the computer programming-based automatic programming method, the programmer first automatically programs the CAD function of the software to construct the geometric figure, and then uses the CAM function to set the geometric parameters to create the NC machining program.
The more commonly used CAD/CAM softwares are Mastercam, Pro/e, UG, etc. The automatic programming software for metalworking center line cutting machine tools uses domestic CAXA.
1. Workpiece materials and blank mold working parts generally use forged blanks, and the wire cutting process is often carried out after quenching and tempering. Due to the influence of the hardenability of the material, when the metal is removed and cut off in a large area, the relative equilibrium state of the residual stress inside the material is destroyed and deformed, which affects the processing precision and even causes sudden cracking of the material during the cutting process. In order to reduce this effect, in addition to alloying tool steels (such as Cr12, Cr12MoV, CrWMn) with good forging properties, good hardenability and low heat treatment deformation, the mold blank forging and heat treatment process should also be used. Properly.
2. Mold preparation step The preparation process of the mold blank refers to all the processing steps before the in-line cutting processing of the punch or the die.
(1) Preparation process of the die 1) The material to be cut is cut by a sawing machine.
2) Forging improves the internal structure and forges into the desired shape.
3) Annealing eliminates forging internal stress and improves processability.
4) Planing (milling) Plane six sides and leave a grinding allowance of 0.4 to 0.6 mm.
5) Grind out the upper and lower planes and the adjacent two sides, diagonal.
6) Mark the position of the edge contour and the hole (screw hole, pin hole, threading hole, etc.).
7) Machining hole part
When the die is large, in order to reduce the amount of wire cutting, the hole leakage part of the hole is cut out (car), and only the cutting edge height is cut; for the material with poor hardenability, part of the material of the hole can be removed, leaving 3 ~ 5mm cutting margin.
8) Hole machining, screw hole, pin hole, threading hole, etc.
9) Quenching meets design requirements.
10) Grind and grind the upper and lower planes and adjacent sides, diagonal.
11) Demagnetization treatment (2) Preparation process of the punch The preparation process of the punch can be performed by referring to the preparation process of the die according to the structural characteristics of the punch, and removing the unnecessary process. However, the following points should be noted:
1) For the convenience of processing and clamping, the blank is generally forged into a parallelepiped. For a punch having the same size and shape and a small cross-sectional size, several punches can be made into one blank.
2) There should be sufficient cutting allowance (generally not less than 5mm) between the cutting contour of the punch and the side of the blank. The clamping part is also left on the blank.
3) In some cases, in order to prevent deformation of the mold blank during cutting, a threading hole is formed in the mold blank. The introduction procedure for cutting begins with the threading hole.
Till now we can do more than 100 style of Steel wheelbarrow with below specifications,
*Round handle, square handle and wooden handle.
*Metal tary and plastic tray.
*Rubber Pneumatic Wheel ,rubber solid wheel, PU foamed wheel.
Also we can do as your require.
The thickness of Garden Wheelbarrow tray we usually do 0.6-1.2mm. usually a Garden Wheelbarrow have d standard thickess, but we can do your thickness accordingly to your require.
The thickness of frame, usually we do 1.0mm or 1.2mm. if you like other thickness, we can do it for you.
Size of wheels, pattern of wheels, also can change as your require. If a
Wheel Barrow we do it with pneumatic wheels, and if you like solid
