Technical Field

The invention belongs to the field of profile steel production equipment, and particularly relates to a buffer resetting device of a sizing machine.

Background

Iron and steel plays a very important role as a basic industry of the national manufacturing industry. The profile steel production equipment is key equipment for producing profile steel.

In the section steel production equipment, a rolled piece rotates through a roller way of a rolling mill, collides with a sizing plate at a certain speed, and is positioned through the sizing plate after stopping. However, the current sizing plate portion has several drawbacks, mainly represented by:

1. the rolled piece is in rigid impact on a sizing plate of the sizing machine, and the sizing plate is not provided with a buffer device and is used for absorbing and eliminating impact load.

2. After the rolled piece strikes the fixed length plate, the rolled piece can return backwards due to the fact that no buffer device exists, and the fixed length precision of the length direction of the rolled piece is reduced.

3. The rigid impact can cause damage to the sizing machine, and particularly easily causes the risk of oil leakage of a lifting oil cylinder in a sizing plate and the risk of hydraulic impact.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a buffer resetting device of a scale so as to solve the defects in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme:

shear gauge buffering resetting means installs on shaped steel production facility, its characterized in that: the hydraulic resetting device is arranged in the middle of the fixed-length rack; two hydraulic buffer devices are symmetrically arranged on the sizing machine frame on two sides of the hydraulic reset device; two rotary opening devices are respectively arranged on two sides of the fixed-length rack; the outer side ends of the hydraulic reset device, the two hydraulic buffer devices and the two rotary distraction devices are fixedly connected with a sizing baffle together.

According to the optimized scheme, the hydraulic reset device comprises a reset oil cylinder arranged on the sizing rack, a reset rod is fixedly connected to a piston rod of the reset oil cylinder, and the end portion of the reset rod is connected to the middle of the positioning baffle through a rotating shaft.

According to the optimized scheme, the hydraulic buffering devices are buffering hydraulic cylinders symmetrically arranged on the sizing rack; the piston rod of the buffer hydraulic cylinder is directly connected to the sizing baffle.

The scheme of optimizing, rotate and strut the device and including fixed the pivot that struts that sets up in the scale frame, strut fixedly connected with in the pivot and strut the pole, strut the other end of pole and connect on the scale baffle.

The optimized scheme is that the fixed-length baffle comprises a piston rod and two fixed-length seats, the piston rod is connected with the reset rod and the two buffer hydraulic cylinders, the two piston rod and the two fixed-length seats are connected with the opening rod, and the fixed-length seats are fixedly connected with the fixed-length plates through bolts.
