Description

Technical Field

[0001] This utility model relates to the field of mold steel technology, and in particular to a polishing device for processing mold steel. Background Technology

[0002] Die steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. Molds are the main processing tools for manufacturing parts in industries such as machinery manufacturing, radio instruments, motors, and electrical appliances. During the mold manufacturing process, the die steel needs to be polished.

[0003] A search revealed a Chinese patent (application number "202321860572.8") disclosing "a polishing device for processing mold steel." This polishing device includes a housing, inside which a transmission mechanism is installed. A mounting plate is installed at the bottom of the transmission mechanism. A shaft is connected to the bottom center of a retaining plate via a bearing. A connecting arm is fixedly installed at the bottom center of the retaining plate, with the shaft passing through the interior of the connecting arm. Both the left and right sides of the bottom of the connecting arm are movably connected to transmission gears via rotating shafts. Polishing wheels are installed at the bottom of each transmission gear. However, the polishing wheels in this polishing device do not rotate along their own axis during rotation; instead, they rotate irregularly, causing the polishing wheels to come into contact with the steel and damage its surface, resulting in low practicality. Utility Model Content

[0004] This utility model provides a polishing device for processing mold steel, which solves the problem that the polishing wheel of the polishing device proposed in the prior art does not rotate along its own axis during the rotation process, but rotates irregularly, causing the polishing wheel to hit the steel and damage the steel surface, resulting in low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A polishing device for processing mold steel includes an operating table. A lifting mechanism is provided on the top of the operating table. The lifting mechanism includes two side plates, mounting plates fixed to the upper outer wall of one side of each of the two side plates, connecting plates fixed to the lower outer wall of one side of each of the two side plates, and two lifting cylinders bolted to the outer wall of the top of the operating table. A polishing assembly is provided on the mounting plates. The polishing assembly includes a polishing motor, a mounting shaft connected to the outer wall of one end of the output shaft of the polishing motor via a coupling, and a polishing wheel bolted to the outer wall of the mounting shaft. A lateral adjustment mechanism is provided on the top of the operating table. The lateral adjustment mechanism includes two mounting blocks fixed to the outer wall of the top of the operating table, an adjustment motor bolted to the outer wall of one side of each mounting block, and a first... The system comprises a screw, two sliding plates respectively screwed to the outer wall of the first screw, and a support plate fixed to the top outer wall of the two sliding plates. The support plate is provided with a longitudinal adjustment mechanism, which includes a second screw, a slider screwed to the outer wall of the second screw, and an electromagnetic chuck bolted to the top outer wall of the slider. The support plate is provided with a fixing assembly, which includes a first fixing plate bolted to one side outer wall of the support plate, a rotary motor bolted to one side outer wall of the first fixing plate, a rotating block bolted to one end outer wall of the output shaft of the rotary motor, a second fixing plate bolted to one side outer wall of the support plate, a third screw penetrating and screwed to one side outer wall of the second fixing plate, a displacement plate connected to one end outer wall of the third screw via a bearing, and a pressing plate connected to one side outer wall of the displacement plate via a bearing.

[0007] Preferably, the operating platform has slide rails on both outer walls, and the two ends of the connecting plate are slidably installed in the two slide rails respectively. The connecting plate is respectively connected to the outer wall of the bottom end of the piston rod of the two lifting cylinders by bolts.

[0008] Preferably, a mounting bracket is fixed on one side of the outer wall of the mounting plate, and the polishing motor is connected to the outer wall of one side of the mounting plate by bolts. One end of the mounting shaft passes through and is connected to the outer wall of one side of the mounting plate by a bearing.

[0009] The above scheme uses a lifting cylinder piston rod to lower the connecting plate, which in turn lowers the two side plates, mounting plate, polishing motor, and polishing wheel. The output shaft of the polishing motor drives the mounting shaft and polishing wheel to rotate, thereby polishing the mold steel.

[0010] Preferably, one end of the first screw is connected to the outer wall of one side of the mounting block via a bearing, and two limiting rods are fixed on the outer walls of one side of each of the two mounting blocks, and the two sliding plates are respectively slidably mounted on the outer walls of the two limiting rods.

[0011] Preferably, a channel is formed on the top outer wall of the support plate, and one end of the second screw is connected to the inner wall of one side of the channel through a bearing. The second screw passes through and is connected to the outer wall of one side of the support plate through a bearing, and the slider is slidably installed in the channel.

[0012] Preferably, the bottom of the displacement plate abuts against the top outer wall of the support plate, and the displacement plate and the support plate form a sliding fit. Rubber pads are fixed on one side of the outer wall of the rotating block and the extrusion plate.

[0013] The above scheme involves adjusting the motor output shaft to drive the first screw to rotate. The first screw then moves the slide plate, support plate, electromagnetic chuck, rotating block, and extrusion plate, thereby moving the mold steel along the length of the operating table. Rotating the second screw moves the plate-shaped mold steel held by the electromagnetic chuck. Rotating the third screw moves the extrusion plate, which, in conjunction with the rotating block, extrudes and fixes the cylindrical mold steel. The rotating motor output shaft then drives the rotating block to rotate, thus rotating the cylindrical mold steel.

[0014] The beneficial effects of this utility model are as follows:

[0015] The output shaft of the adjusting motor drives the first screw to rotate, which in turn moves the slide plate, support plate, electromagnetic chuck, rotating block, and extrusion plate, thus moving the mold steel along the length of the operating table. Rotating the second screw moves the plate-shaped mold steel held by the electromagnetic chuck. Rotating the third screw moves the extrusion plate, which, in conjunction with the rotating block, extrudes and fixes the cylindrical mold steel. The output shaft of the rotating motor drives the rotating block to rotate, thus rotating the cylindrical mold steel. This allows for polishing of both cylindrical and plate-shaped mold steel without the polishing wheel impacting the mold steel, preventing damage and improving practicality.
