Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, a simple roll-changing pin operating device for roll changing comprises a rolling mill body, wherein upper and lower rolls are arranged in the rolling mill body, one side of each of the upper and lower rolls is a transmission side, and the other side of each of the upper and lower rolls is an operation side; the upper roller and the lower roller are connected with a roller changing frame; and the roll changing frame is provided with a roll changing assembly.

The roll changing assembly comprises connecting rods 2 arranged on two sides of a bearing seat 8, 4 connecting rods 2 are arranged corresponding to the upper and lower rolls, and the connecting rods 2 penetrate through a bearing seat on the transmission side and are stopped at a bearing seat on the operation side; two roll changing pins 1 are arranged on the connecting rod 2, the two roll changing pins 1 are respectively arranged in long grooves of a transmission side bearing seat and an operation side bearing seat, and work simultaneously to lock, so that an upper roll and a lower roll of the rolling mill form an integral structure; and one end of the connecting rod 2, which is positioned on the bearing block on the operation side, is provided with an adjusting component, and the position states of the two roll changing pins 1 are adjusted through the adjusting component.

As shown in fig. 3, the adjusting assembly comprises a spring 5 sleeved on the end of the connecting rod 2; a spring sleeve 4 is arranged outside the spring 5; one end of the spring sleeve 4 is embedded into the roller changing frame, and the other end of the spring sleeve is connected with the spring pressing block 3; the outer side of the spring pressing block 3 is connected with a handle 6, and the inner side of the spring pressing block is connected with the end of the connecting rod 2 through a bolt.

The outer side wall of one end, embedded into the roller changing frame, of the spring sleeve 4 is square or polygonal, the connecting rod 2 is fixed, and error deflection is prevented.

The handle 6 is U-shaped and is connected with the spring pressing block 3 through a bolt. The handle 6 can also be M-shaped or disc-shaped, so that the handle is convenient for workers to hold and turn, and the handle 6 is connected with the spring pressing block 3 through a bolt, so that the maintenance and protection are convenient.

And one end of the spring sleeve 4 is embedded into the connecting rod 2 on one side of the roller changing frame and is also sleeved with a self-lubricating sleeve 7, so that the resistance borne by the connecting rod 2 when the connecting rod is pulled out is reduced.

The working process of the device is as follows:

as shown in fig. 4, when the rolling mill works daily, the device is in a non-roll-changing state, at the moment, the roll-changing pin 1 is in a horizontal state, and the bearing seat is not locked; when roll changing operation is needed, the device is in a roll changing state, workers hold the handle 6 by hands and pull out the connecting rod 2, the spring sleeve 4 is separated from the roll changing frame and rotates 90 degrees to the vertical direction, the roll changing pin 1 is in a vertical state, the roll changing pin 1 is respectively arranged in the long grooves of the transmission side bearing block and the operation side bearing block and is locked simultaneously, so that the upper roll and the lower roll of the rolling mill form an integral structure, and subsequent roll changing operation is convenient.

The device has the advantages that:

the device can conveniently and quickly complete the connection of the roll changing pin 1 at the operation side of the rolling mill, so that the upper and lower rolls which are changed in pairs form a whole, and the roll changing cylinder can be quickly pushed out and changed. The roller changing device is accurate in place, time-saving and labor-saving, improves the roller changing efficiency, reduces the problem of long standby time of a rolling line, and improves the utilization rate of equipment.
