Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a blank circulation grinding device. Background Technology

[0002] After the billet is cast, its surface needs to be polished with sandpaper of different grits to ensure its accuracy. Currently, most polishing machines on the market can only polish a single billet. For example, patents CN118893534B and CN111168536B, which are also polishing devices, can only use a fixed base or slewing bearing to hold a single billet for continuous polishing. Because the billet needs to be repeatedly clamped, this not only increases the labor intensity of employees and raises the cost of billet polishing, but also increases the working time of billet polishing and reduces polishing efficiency.

[0003] Therefore, how to design a blank circulation grinding device with low labor intensity, low grinding cost, fast grinding speed and high grinding efficiency is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] This invention provides a billet circulation grinding device, which solves the technical problems of high labor intensity, high grinding cost, long grinding time and low grinding efficiency of existing grinding devices.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a billet circulating grinding device, comprising: a feeding section, a pushing mechanism, a grinding machine, and a discharging section. The feeding section includes a feeding frame and multiple rollers. The pushing mechanism includes a fixed seat and a pushing part. The grinding machine includes a housing, a conveying part, and a grinding part. The feeding frame, the fixed seat, the housing, and the discharging part are arranged sequentially along the billet conveying direction. The multiple rollers are arranged perpendicular to the billet conveying direction and rotate at intervals on the feeding frame along the billet conveying direction. The billet rolls on the multiple rollers. The housing is provided with a conveying channel arranged along the billet conveying direction and extending through both ends. The conveying part passes through the conveying channel in the same direction, and its input end and output end are respectively... The conveying section extends through both ends of the conveying channel. It is fixed to the housing and can transport the billet along the billet conveying direction. The fixed end of the pushing section is fixed to the fixed base and its pushing end reciprocates along the perpendicular direction of the billet conveying to push the billet that has rolled out of the multiple rollers to the input end of the conveying section. The fixed end of the grinding section is fixed inside the housing above the conveying section and its grinding end contacts the billet transported on the conveying section for grinding. The unloading section is provided with a unloading chute. One end of the unloading chute is connected to the output end of the conveying section and the other end is in contact with one side of the loading frame to manually transport the billet conveyed by the conveying section to the multiple rollers, so as to realize the multiple-cycle grinding of the billet.

[0006] The beneficial effects of this invention are: a completely new design of the billet grinding device, which first uses the pushing part of the pushing mechanism to push the billets on multiple rollers to the conveying part of the grinding machine, and then uses the two ends of the unloading chute of the unloading part to connect with the output end of the conveying part and multiple rollers on the loading frame respectively. Multiple billets can be ground synchronously and cyclically by the grinding part, eliminating the billet clamping time and improving the billet grinding efficiency.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the feeding unit also includes a feeding motor, which is fixed on the feeding frame and is connected to multiple rollers via belts, chains, sprockets, or gears.

[0009] The further beneficial effect of adopting the above is that the feeding motor can drive multiple rollers to rotate, thereby realizing the active conveying of the billet.

[0010] Furthermore, the top of the feeding rack descends sequentially from the direction away from the fixed seat to the direction near the fixed seat, so that the height of the multiple rollers from the direction away from the fixed seat to the direction near the fixed seat decreases sequentially.

[0011] The further beneficial effect of adopting the above is that by lowering the top of the feeding rack sequentially from the direction away from the fixed seat to the direction closer to the fixed seat, the billet can be subjected to gravity and roll autonomously along multiple rollers.

[0012] Furthermore, the fixed base includes a base, a lifting mechanism, and a transfer plate. The feeding rack, the base, and the housing are arranged sequentially along the billet conveying direction. The fixed end of the lifting mechanism is fixed to the base, and its lifting end reciprocates along the height direction. The transfer plate is fixed to the lifting end of the lifting mechanism. The fixed end of the pushing part is fixed to the transfer plate to convey the billet between the feeding rack and the conveying part at different heights.

[0013] The further beneficial effect of adopting the above is that, according to the height of multiple rollers and the height of the input end of the conveying section, the height of the lifting end of the elevator is adjusted sequentially so that the transfer plate and the pushing part are adapted to the height of the rollers and the height of the conveying section respectively, so that the billet can be transferred between rollers of different heights and conveying sections of different heights.

[0014] Furthermore, the grinding section includes a support frame, a rotating motor, a rotating box, a grinding motor, and a grinding wheel. The support frame is the fixed end of the grinding section and is fixed inside the housing above the conveying section. The rotating motor is located inside the housing and fixed on the support frame, and its output shaft rotates about the height direction of the housing. The rotating box is located inside the housing and fixed on the output shaft of the rotating motor, and its side wall has a shaft hole. The grinding motor is fixed inside the rotating box, and its output shaft rotates about the height direction perpendicular to the housing, with the output shaft extending out of the shaft hole. The grinding wheel is the grinding end of the grinding section and is fixed to the end of the grinding motor that extends out of the shaft hole, so as to grind the blank on the conveying section with the drive of the rotating motor and the grinding motor.

[0015] The further beneficial effect of adopting the above is that: first, the rotating box is driven to rotate by a rotating motor, and then the grinding wheel is driven to rotate by a grinding motor. This allows the grinding wheel to rotate on its own axis while it is revolving around the revolution, thus efficiently driving the grinding wheel to grind the blank.

[0016] Furthermore, there are multiple grinding motors and grinding wheels arranged opposite to each other, and multiple shaft holes are spaced apart in the rotating box; the output shafts of the multiple grinding motors respectively rotate out of the multiple shaft holes.

[0017] Furthermore, the grinding section also includes a drive roller, a driven roller, a grinding belt, and a drive roller motor. The drive roller and the driven roller are spaced apart along the height direction of the housing and are rotatably connected inside the housing in a direction perpendicular to the billet conveying direction. The drive roller and the driven roller are located above the conveying section and placed on one side of the grinding wheel. The grinding belt is tumbledly connected to the drive roller and the driven roller. The drive roller motor is fixed to the housing and is connected to the drive roller via a belt, chain sprocket, or gear to drive the grinding belt to grind the billet on the conveying section.

[0018] The further beneficial effect of adopting the above is that by using the drive roller motor to drive the active roller to rotate, the grinding belt can be driven to rotate, and the blanks on the conveyor section can be ground.

[0019] Furthermore, the driving wheel, the driven roller, and the grinding belt are arranged opposite to each other and spaced apart along the blank conveying direction. Attached Figure Description
