Detailed Description

In order to further describe the technical means and effects adopted by the utility model for achieving the preset aim, the following detailed description is given below of the specific implementation, structure, characteristics and effects according to the utility model with reference to the attached drawings and the preferred embodiment.

As shown in fig. 1-2, a four-roller cold rolling mill for processing titanium 3D curved surface profiling materials comprises a roller wheel 1 group and an auxiliary wheel 2 group, wherein the roller wheel group and the auxiliary wheel group respectively comprise two roller wheels 1 and two auxiliary wheels 2, the rim surfaces of the two roller wheels 1 are of a segmented structure and are divided into a big column section and a small column section according to the diameter, the two radial surfaces of the two roller wheels 1 are on the same horizontal plane, the big column section and the small column section are in staggered fit, namely the rim surface of the big column section of one roller wheel 1 is opposite to the rim surface of the small column section of the other roller wheel 1, and the two roller wheels 1 can also be regarded as being arranged based on center point center symmetry, and then a roller region is formed in the space between the big column section and the small column section on one side of the two roller wheels 1, and is used for rolling materials.

However, the rolling process is performed on the material from two directions only through the two rolling wheels 1, the process can be well completed when the rolling machine is used on the material with lower hardness, and when the rolling machine is used on the material with higher hardness such as titanium material and the material needs to be rolled into a curved surface shape, the rolling of the two rolling wheels 1 is easy to cause dislocation after extrusion stress due to higher hardness of the material, namely, the rolling wheel 1 deviates from the original position, so that the tolerance of the processed material is larger, and the problem that the dislocation of the rolling wheel 1 cannot be solved by the four-roller cold rolling mill in the prior art.

Therefore, in order to prevent the dislocation of the rolling wheel 1 in the working process, four rolling wheels used for rolling in a four-roller cold rolling mill in the prior art are changed into two rolling wheels, the wheel grooves of the two rolling wheels 1 are improved, the special shape for rolling materials is formed by the joint parts of the large column section and the small column section on the two rolling wheels 1, the rolling surfaces of the other two rolling wheels 1 are supplemented, in the embodiment, the large column section and the small column section of the two rolling wheels 1 form a similar stepped structure, namely, the radial surfaces of the large column section and the small column section are connected with each other, and the diameter of the small column section is smaller than that of the large column section, because the two rolling wheels 1 are symmetrically arranged based on a center point center, the two rolling wheels 1 are respectively defined as a first rolling wheel 1 and a second rolling wheel 1, the rim surface of the large column section of the first rolling wheel 1 and the rim surface of the small column section of the second rolling wheel 1 are in rolling contact with each other, and the special shape of the rolling section is formed on the roll section of the material after the projection area is formed according to the shape of the special shape required to be formed.

The positions of the other two rolling wheels 1 are set to be two auxiliary wheels 2, the rim surfaces of the two auxiliary wheels 2 are cylindrical, the rim surfaces of the two auxiliary wheels 2 are in rolling fit with the radial surfaces of the two rolling wheels 1, when the two rolling wheels 1 rotate and roll the material, due to the fact that the hardness of titanium materials is higher, when the titanium materials are to be processed into curved surfaces, the titanium materials are rolled and fit on the side surfaces of the rolling wheels 1 through the two auxiliary wheels 2 for preventing the two rolling wheels 1 from being staggered, the two auxiliary wheels 2 rotate along with the rotation of the two rolling wheels 1, when the two auxiliary wheels 2 are abutted to the side surfaces of the two rolling wheels 1, the large column sections of the two rolling wheels 1 are close to the side walls of the small column sections, the side walls of the large column sections of the two auxiliary wheels 1 are in rolling connection with each other, the side surfaces of the two rolling wheels 1 can be pressed by a pressing device, the cross sections of the rolling areas can be prevented from being reduced due to the fact that the pressing force is excessively large, the two auxiliary wheels 2 are abutted to the two rolling wheels 1 can be prevented from being abutted to each other, and the rolling tolerance of the two rolling wheels is prevented from being staggered, and the machining tolerance of the material is reduced.

Because the rolling wheel 1 is used for processing metals with higher hardness such as titanium materials, and the processing surface comprises a curved surface, the rolling surface of the rolling wheel 1 is easy to damage after long-time processing, and the rolling wheel 1 is more seriously worn when the rolling wheel 1 is rolled by the metal materials with higher hardness such as titanium materials, so that the rolling wheel 1 needs to be replaced or maintained regularly, and the rolling wheel 1 of the cold rolling mill in the prior art is directly connected to the rotating shaft 3 in a transmission way, and the whole rolling wheel 1 needs to be detached or replaced when the maintenance or the replacement of the rolling wheel 1 is needed, so that the maintenance cost is higher. Meanwhile, when rolling materials in different shapes, the rolling wheels 1 with different rolling surfaces need to be replaced, the overall weight of the rolling wheel 1 is heavy, and the overall replacement of the rolling wheel 1 is inconvenient.

Therefore, in order to facilitate the quick replacement of the roller wheel 1 after the roller surface is damaged, the roller wheel 1 is divided into a wheel seat 8, a wheel sleeve 7 and a rotating shaft 3 through the structure of the roller wheel 1, the wheel seat 8 is in transmission connection with the rotating shaft 3, the transmission connection can drive the wheel seat 3 to rotate, the connection part of the wheel seat 8 and the rotating shaft 3 can be specifically the wheel seat 8 through key connection, the wheel sleeve 7 is detachably sleeved on the wheel seat 8, the wheel seat 8 and the wheel sleeve 7 cannot generate relative rotation, the inner side wall of the wheel sleeve 7 is mutually attached to the rim surface of the wheel seat 8, the wheel sleeve 7 is sleeved in the wheel seat 8 in a sliding manner during installation, the wheel sleeve 7 cannot generate displacement based on the radial surface direction of the wheel sleeve 7, then the wheel sleeve 7 is fixed through bolts, the displacement based on the axial surface direction of the wheel sleeve is prevented, the wheel sleeve 7 has a certain thickness, the roller wheel 1 can be prevented from deforming when the material is rolled, the wheel sleeve 7 only needs to be replaced after the wheel sleeve 7 is arranged on the outer side of the wheel seat 8, the material is replaced, the wheel sleeve 7 only needs to be replaced, and the wheel sleeve 7 can be replaced in the same shape as the material, and the material can not be replaced in the abrasion mode.

In order to prevent the wheel sleeve 7 from displacement along the axial direction of the wheel seat 8 when being machined after being mounted, the baffle 6 extends out of the plane of the radial surface of the wheel seat 8, so that the diameter of the baffle 6 is larger than the inner diameter of the wheel sleeve 7, the side surface of the wheel sleeve 7 is abutted with the baffle 6 after the wheel sleeve 7 is sleeved on the wheel seat 8, and the baffle 6 limits the horizontal direction of the wheel sleeve 7.

After the wheel sleeve 7 is sleeved on the wheel seat 8, sliding in the horizontal direction can occur, and relative rotation with the wheel seat 8 can also occur, because in the processing process, the roller wheel 1 is used for rolling materials, and the materials need to rotate to move along one direction after rolling, if the wheel sleeve 7 and the wheel seat 8 relatively rotate, the wheel seat 8 can not move the materials through the driving wheel sleeve 7, so that relative stationarity between the wheel sleeve 7 and the wheel seat 8 needs to be ensured, a plurality of clamping teeth 5 are arranged on the rim surface of the wheel seat 8 through arranging a plurality of clamping teeth 5 on the wheel seat 8, the clamping teeth 5 are perpendicular to the radial surface of the wheel seat 8, and clamping grooves matched with the clamping teeth 5 are arranged on the wheel sleeve 7, and when the clamping grooves on the wheel sleeve 7 are installed, the clamping grooves are aligned with the clamping teeth 5 and are sleeved on the wheel seat 8 along the radial direction, so that the wheel seat 8 and the wheel sleeve 7 cannot relatively rotate.

After the wheel sleeve 7 is mounted on the wheel seat 8, one side of the wheel sleeve 7 is abutted to the baffle 6 of the wheel seat 8, but the other side of the wheel sleeve 7 is not limited, so that the wheel sleeve 7 is fixed through bolts, the wheel sleeve 7 is connected with the wheel seat 8 through the bolts, and falling of the wheel sleeve 7 in the rolling process is avoided.

In the process of rotating the roller wheel 1, the auxiliary wheel 2 is always abutted to two radial surfaces of the roller wheel 1, if the auxiliary wheel 2 is kept motionless, the roller wheel 1 and the auxiliary wheel 2 always generate relative movement, huge noise is generated after friction, and the rotation moment of the roller wheel 1 can be reduced after mutual friction, so that the auxiliary wheel 2 is required to synchronously rotate the roller wheel 1, conical gears 4 are connected to the rotating shafts 3 of the auxiliary wheel 2 and the roller wheel 1 in a transmission manner, the adjacent conical gears 4 are meshed with each other, the auxiliary wheel 2 synchronously rotates along with the roller wheel 1, the noise is reduced, and meanwhile, any rotating shaft or 3 can be connected to external driving equipment to realize rotation.
