Description

Technical Field

[0001] The invention relates to the technical field of grinding of roll forgings, in particular to a grinding machine for producing roll forgings. Background Art

[0002] Rollers are tools that cause plastic deformation of metal (rolled material). They are important consumable parts that determine the efficiency of the rolling mill and the quality of the rolled material. Rollers are important parts of the rolling mill in a steel mill. They use the pressure generated by a pair or a group of rolls when rolling to roll steel. Before the rolls are used, the surface of the roll forgings needs to be polished. During the grinding process of the roll forgings, rough grinding is generally performed first, followed by fine grinding.

[0003] When the roll forgings are placed on a grinding machine for fine grinding, in order to grind the rolls smoothly, people need to observe the grinding conditions of the rolls at all times. However, when the grinding machine is grinding the rolls, cooling water needs to be sprayed at the grinding position, so there will be a large amount of water on the rolls, which makes it inconvenient for workers to observe the rolls. Summary of the invention

[0004] The object of the present invention is to provide a grinding machine for producing roll forgings to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a grinder for producing rolling mill forgings, comprising a grinding machine body, a clamp for fixing the rolling mill is installed in the middle of the grinding machine body, a grinding assembly is installed in the middle of the grinding machine body corresponding to the position of the rolling mill, the grinding assembly can move forward, backward, left and right, a fixed frame is fixedly installed on the top of the grinding assembly, a sliding frame is slidably installed at one end of the fixed frame away from the grinding assembly, a mounting frame is installed at the bottom of the sliding frame, a rotating rod is rotatably installed in the middle of the mounting frame, a water-absorbing sponge is fixedly installed on the outer side of the middle of the rotating rod, a motor is fixedly installed at one end of the mounting frame, and the output end of the motor is fixedly connected to one end of the rotating rod.

[0006] As a further preferred embodiment of the present technical solution, a pressing frame is fixedly mounted on one side of the mounting frame, and an inner ring of the pressing frame is arranged in pressing contact with the water-absorbing sponge.

[0007] As a further preferred embodiment of the present technical solution, the extrusion frame is arranged in a bell-mouth shape.

[0008] As a further preferred embodiment of the present technical solution, a slide groove is provided in the middle of one end of the fixed frame away from the grinding assembly, a slider is fixedly installed at one end of the sliding frame, the slider is slidably connected to the slide groove, and a fastening bolt is installed at one end of the slider away from the sliding frame.

[0009] As a further preferred embodiment of the present technical solution, sliding holes are symmetrically opened in the middle of the sliding frame, sliding rods are symmetrically fixedly installed on the top of the sliding frame, the sliding rods are slidably connected to the sliding holes, a threaded sleeve is rotatably installed in the middle of the sliding frame, a worm gear is fixedly installed on the top outer side of the threaded sleeve, a screw is threadedly connected to the middle of the threaded sleeve, the screw is rotatably connected to the top of the mounting frame through a bearing, a worm is rotatably installed on one side of the top of the sliding frame corresponding to the position of the worm gear, and the worm is meshingly connected to the worm gear.

[0010] As a further preferred embodiment of the present technical solution, a hand wheel is fixedly mounted on the end of the worm.

[0011] The present invention provides a grinding machine for producing roll forgings, which has the following beneficial effects: (1) The present invention fixes the roller on a clamp and places a water-absorbing sponge close to the roller. The motor drives the water-absorbing sponge to rotate, thereby absorbing the water on the roller. Then, as the water-absorbing sponge rotates, the inner ring of the squeezing frame squeezes the water-absorbing sponge, and the water inside the water-absorbing sponge is squeezed out and flows out from the large opening of the squeezing frame. The water-absorbing sponge is always able to absorb the water, which facilitates people to observe the grinding condition of the roller.

[0012] (2) When grinding rollers of different sizes, the present invention adjusts the position between the fixed frame and the sliding frame, and then drives the worm to rotate through the hand wheel. The meshing of the worm and the worm wheel drives the threaded sleeve to rotate. The threaded connection between the threaded sleeve and the screw drives the mounting frame to move up and down along the trajectory of the sliding hole, so that the water-absorbing sponge can be moved up and down to be close to rollers of different diameters.

[0017] When the water-absorbing sponge 8 rotates to absorb the water on the roller, the inner ring of the squeezing frame 10 will squeeze the water-absorbing sponge 8 under the rotation of the water-absorbing sponge 8, and the water inside the water-absorbing sponge 8 will be squeezed out, so that the water-absorbing sponge 8 can absorb the water at all times.

[0018] like Figures 1 to 4 As shown, the extrusion frame 10 is arranged in a bell-mouth shape.

[0019] It is convenient for water to flow out from the large opening of the extrusion frame 10.

[0020] like Figures 1 to 4 As shown, a slide groove 11 is provided in the middle of one end of the fixed frame 4 away from the grinding assembly 3, a slider 12 is fixedly installed at one end of the sliding frame 5, the slider 12 is slidably connected to the slide groove 11, and a fastening bolt 13 is installed at one end of the slider 12 away from the sliding frame 5.

[0021] By loosening the fixing bolts 13 between the fixed frame 4 and the sliding frame 5, sliding the fixed frame 4 and the sliding frame 5 relative to each other, and then fixing the position between the fixed frame 4 and the sliding frame 5 by the fastening bolts 13, the water-absorbing sponge 8 can be moved left and right.

[0022] like Figures 1 to 4As shown, a sliding hole 14 is symmetrically opened in the middle of the sliding frame 5, a sliding rod 15 is symmetrically fixedly installed on the top of the sliding frame 5, and the sliding rod 15 is slidably connected to the sliding hole 14.
