Use of counterweight blocks

The counterweight block can be used to make accessories on different products in different fields, which fully plays the role of increasing weight and maintaining balance.

Application areas of counterweight blocks

Drilling machine counterweight block, excavator counterweight block, shipyard counterweight block, experimental factory counterweight block, elevator counterweight block, crane counterweight block, pile driver counterweight block, forklift counterweight block, forklift counterweight block, crane counterweight block, container test counterweight block, lift counterweight block, electrical counterweight block, construction machinery counterweight block.

Features of counterweight blocks

1. Counterweight block is a relatively economical blank forming method, which can show its economy for parts with complex shapes. Such as the cylinder block and cylinder head of the automobile engine, the ship propeller and the artwork. Some parts that are difficult to cut, such as nickel-based alloy parts of gas turbines, cannot be formed without counterweight methods.

2. The parts size and weight of the counterweight block have a wide range of adaptation, and the type of metal is almost unrestricted.

3. The parts have general mechanical properties at the same time, but also have comprehensive properties such as shock absorption, which can not be done by other metal forming methods such as forging, rolling, welding, stamping, etc.

Classification of counterweights

The counterweight blocks are generally classified according to the modeling method, and are customarily divided into ordinary sand counterweight blocks and special counterweight blocks. Ordinary sand weight blocks include wet sand, dry sand and chemical hardening sand.

Special counterweight blocks can be divided into two categories according to the different modeling materials

The first type uses mineral sand as the main molding material, such as investment mold counterweight block, shell counterweight block, negative pressure counterweight block, mud counterweight block, solid counterweight block, ceramic counterweight block, etc.

One type uses metal as the main casting material, such as metal counterweight block, centrifugal counterweight block, continuous counterweight block, pressure counterweight block, low pressure counterweight block.

Counterweight block production process

The metal is melted into a liquid that meets the requirements and poured into the cast, and the castings with predetermined shape, size and performance after cooling and solidification and cleaning treatment are classified: generally classified according to the modeling method, and it is customary to divide into ordinary sand counterweight blocks and special counterweight blocks.

The counterweight block process can be divided into three basic parts, namely, counterweight block metal preparation, mold preparation and casting treatment. Counterweight block metal refers to the metal material used for casting castings in the production of counterweight blocks, which is an alloy composed of a metal element as the main component and other metal or non-metal elements, which is commonly called counterweight block alloy, mainly cast iron, cast steel and counterweight block nonferrous alloy.

Counterweight block production requirements: some castings due to requirements, but also after casting post-treatment, such as heat treatment, rust prevention treatment, rough processing, etc.
