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.

Detailed Description

Examples

As shown in figure 1, the sizing machine buffering and resetting device is installed on the section steel production equipment, and the sizing machine corresponds to a roller way and a rolled piece on the section steel production equipment.

The sizing machine buffering resetting device comprises a sizing rack 8, and a hydraulic resetting device is arranged in the middle of the sizing rack 8. Two hydraulic buffer devices are symmetrically arranged on the scale rack on two sides of the hydraulic reset device. Two rotary opening devices are respectively arranged on two sides of the fixed-length frame 8. 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. The scale baffle is a general name, and its concrete structure includes the scale seat 6 of connecting reset lever, two buffer hydraulic cylinder's piston rod and two spreader bars jointly, and scale seat 6 passes through 5 fixedly connected with scale boards 4 of bolt.

The implementation modes and the varieties of hydraulic resetting device, hydraulic buffer device and rotation strutting device, wherein this application file has given the optimal design scheme, specifically is:

the hydraulic reset device comprises a reset oil cylinder 9 arranged on the sizing rack, a reset rod 10 is fixedly connected to a piston rod of the reset oil cylinder 9, and the end part of the reset rod 10 is connected to the middle part of the sizing seat 6 of the positioning baffle through a rotating shaft.

The hydraulic buffer device is a buffer hydraulic cylinder 7 symmetrically arranged on the sizing frame. The piston rod of the buffer hydraulic cylinder 7 is directly connected to the sizing seat 6 of the sizing baffle.

The rotary opening device comprises an opening rotating shaft 2 fixedly arranged on the sizing frame, an opening rod 3 is fixedly connected to the opening rotating shaft 2, and the other end of the opening rod 3 is connected to a sizing seat 6 of the sizing baffle. In order to facilitate the fixation, the opening rotating shaft 2 and the opening rod 3 are connected through a flange connecting piece, and the technology can be selected or not selected.

As shown in fig. 2-3, when the rolled piece 11 is transported to the vicinity of the sizing machine through the roller way 12, the sizing plate 4 is driven by the reset cylinder 9, and the sizing plate 4 is put down until the sizing plate 4 is perpendicular to the central line of the roller way, which is also the actual required accurate sizing position of the rolled piece, and at this time, the rolled piece is transported to the position of the sizing plate 4 through the roller way and is completely contacted with the surface of the sizing plate 4. Because the rolled piece is heavy and the roller way transportation speed is relatively high, the rolled piece can cause very big rigid impact to the sizing plate 4, at this moment, two hydraulic buffers 7 behind the sizing plate 4 begin to work, the rigid impact load of the rolled piece to the sizing plate 4 is decomposed and released through the hydraulic buffers 7, until the motion of the rolled piece along the roller way transportation direction is completely stopped, because the piston rod of the hydraulic buffer 7 can retract backwards in the process of absorbing the impact load of the rolled piece, the sizing plate 4 and the rolled piece are driven to retreat until the rolled piece completely stops moving, at this moment, the reset oil cylinder 9 installed behind the sizing plate begins to work, the piston rod of the oil cylinder slowly extends out at a certain speed, the sizing plate and the rolled piece are pushed to reset to the vertical position of the sizing plate and the roller way central line, namely, the accurate sizing position of the rolled piece, at this moment, the reset buffer action of the whole sizing baffle is completed.

The reset oil cylinder pushes the sizing plate and the rolled piece back to the original position at a certain speed, namely the sizing baffle and the roller surface vertical position, so that the accurate sizing of the length direction of the rolled piece is realized, the sizing precision can reach +/-2 mm, and the sizing precision is far higher than that of a sizing machine without a buffer device.

After the rolled piece is processed, the reset oil cylinder 9 works to lift the fixed size plate, and the roller way conveys the rolled piece to pass through and enter the next procedure.
