A cross-cut sawing machine

Abstract

The invention discloses a transverse cutting sawing machine. The transverse cutting sawing machine comprises a frame, a rolling needle guide rail, an anti-skid mechanism, a motor, a driven gear, a sawblade, a frame table, a seat stand, a motor, a speed reducer, a coupling, an oil injecting device, a brake disc, a chuck rotary table, a vice clamping jaw, a clamping type brake, a ring part, a clampand a riding wheel, wherein the bottom of the frame is in sliding connection with a bottom plate through the rolling needle guide rail. The clamping type brake and the brake disc are adjusted by thedevice to enable the ring part to be clamped stably, so that the saw blade reactive force is reduced stably, the installation of a guiding block is matched, so that the cutting of the saw blade is stable, the saw blade is prevented from shaking, the cutting precision is improved, the service life of the saw blade is prolonged, the clamping of the clamp facilitates the stable position limitation ofthe ring part, and the phenomenon that the clamping force is caused to the cutting part when penetrative cutting is conducted on the ring part by the saw blade is avoided; and the supporting on the chuck rotary table is increased through the clamping type brake, the chuck rotary table is prevented from being bent by the pressure of the ring part, and the machining precision is improved.

Description

technical field [0001] The invention relates to a cross-cut sawing machine for segmenting rings, which belongs to the field of engineering equipment, in particular to a cross-cut sawing machine. Background technique [0002] Large-scale ring forgings are one of the important links in the development and production of wind power and large-scale equipment in my country. As manufacturers of wind power supporting facilities such as flanges, bearings, brake discs and yaw rings, they have good market prospects and development space. However, some flanges and bearings have high requirements for product height and performance. However, due to their weight and the ability of ring rolling equipment, forging and processing are relatively difficult. Therefore, rings with very small heights are currently The parts are all heightened (sometimes doubled), and finally all the margins are processed by processing methods to meet the height of the final product, which will waste raw materials ...

Problems solved by technology

However, some flanges and bearings have high requirements for product height and performance. However, due to their weight and the ability of ring rolling equipment, forging and processing are relatively difficult. Therefore, rings with very small heights are currently The parts are all heightened (sometimes doubled), and finally all the margins are processed by processing methods to meet the height of the final product, which will waste raw materials and increase costs and reduce production efficiency.

[0003] In the early stage of development, the blanking sawing machine was modified. The size of the cutting ring has size requirements. The rotation of the chuck is driven by the motor. The clamping method is clamped by mechanical claws. The operating position of the saw blade is to cut from top to bottom. In the process of cutting the product, the rotation speed needs to be manually adjusted. The product is relatively stable at the beginning of the rotation, but it slides down as time goes by. The saw blade has a reverse force during the cutting process, and its verticality difference is relatively large. , and when the product is about to be cut, there is a sawing phenomenon due to the internal stress of the product. When this phenomenon occurs, a saw blade will be scrapped or the cutting will be re-entered, which will increase the cost and reduce the production efficiency. After working for a long time, there is a place at the back that is worn out. For this reason, we propose a cross-cut sawing machine
