Description

Technical Field

[0001] This invention relates to the field of steel ball processing technology, and particularly to a steel ball grading and screening device. Background Technology

[0002] Steel balls are classified into ground steel balls, forged steel balls, and cast steel balls according to their manufacturing process. They are also classified into bearing steel balls, stainless steel balls, carbon steel balls, and copper bearing steel balls, etc. Bearing steel balls are essential basic components in industry. Alloy steel balls are spherical iron alloy wear-resistant bodies produced through forging, spinning, rolling, and casting, with carbon, chromium, manganese, molybdenum, and other main added metallic elements. Because they are designed to fit different bearing sizes, the produced steel balls vary in size, necessitating grading. However, existing grading devices have some problems in operation.

[0003] Current methods for screening steel balls after production cannot quickly and effectively separate the balls by size. Furthermore, most screening processes utilize rolling screens, which easily lead to similar-sized balls clogging the screen mesh. This clogging significantly reduces subsequent screening efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel ball grading and screening device.

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

[0006] A steel ball grading and screening device includes a support base frame. Universal wheels are bolted to the four corners of the support base frame. Side panels are fixedly installed on both sides of the top of the support base frame. Screening plates are evenly distributed between two side panels, and inclined guide grooves are formed inside the screening plates. A fixing plate is bolted to one side of the bottom of each side panel, and a guide plate is installed along the inclined direction on the top side of the fixing plate. A top plate is provided between adjacent screening plates, and a fixing seat is fixed to the bottom of the top plate with screws. An electric telescopic rod is installed at the bottom of the fixing seat, and a second discharge guide rail is installed along the inclined direction on the top side of the side panel.

[0007] As a further improvement of this utility model: a rectangular screening groove is opened through one side of the top of the inclined guide groove, and the width of the rectangular screening groove gradually increases from bottom to top, and the width of the rectangular screening groove is adapted to the diameter of the steel ball.

[0008] As a further improvement of this utility model: the fixed base is provided with equally spaced gap slots, and the inner wall size of the gap slots is adapted to the width size of the screening plate.

[0009] As a further embodiment of this utility model: the outer wall of one side of the side panel has rectangular slots distributed at equal intervals along the inclined direction, and the inner wall size of the rectangular slots is adapted to the inner wall width of the inclined guide groove, and a first discharge guide rail is fixedly installed on the inner wall of the rectangular slots.

[0010] As a further improvement of this utility model: symmetrically distributed limiting rings are welded to the bottom outer wall of the side panel, and L-shaped limiting rods are welded to both outer walls of the fixing seat, with the L-shaped limiting rods slidably inserted into the inner wall of the limiting rings.

[0011] As a further improvement of this utility model: the top outer wall of both the screening plate and the top plate is provided with an inclined angle of 45 degrees.

[0012] Compared with the prior art, the present invention provides a steel ball grading and screening device, which has the following beneficial effects:

[0013] 1. The steel ball grading and screening device designed in this paper pours the steel balls to be screened into the grooves of the bottom fixed plate and the screening plate, arranging the steel balls in a row. The electric telescopic rod at the bottom drives the top plate to repeatedly lift the steel balls, thereby gradually raising them for processing. At this time, in conjunction with the rectangular screening troughs of different diameters, steel balls of different diameters can be quickly introduced and graded for screening. Moreover, the size of the rectangular screening troughs increases from bottom to top, so that the diameter of the screened steel balls increases step by step, which is convenient for later collection.

[0014] 2. The steel ball grading and screening device designed in this way allows the steel balls to roll quickly after they have been graded and screened and fall into the inclined guide trough. The inclined angle inside, combined with the effect of gravity, allows the steel balls to accumulate in the inclined guide trough for a long time. In addition, the fixed base at the bottom has L-shaped limit rods on both sides that slide and insert continuously, which makes the top plate more stable during the reciprocating motion.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1:

[0022] A steel ball grading and screening device, in this embodiment, as follows: Figure 1-3 As shown, the system includes a support base 1, with casters 2 fixed to the four corners of the bottom of the support base 1 by bolts. Side panels 3 are fixedly installed on both sides of the top of the support base 1. Screening plates 4 are fixed between two side panels 3 at equal intervals. Inclined guide grooves 5 are provided inside the screening plates 4. A fixing plate 7 is fixed to one side of the bottom of the side panel 3 by bolts. A guide plate 8 is installed on one side of the top of the fixing plate 7 along the inclined direction. A top plate 9 is provided between adjacent screening plates 4. A fixing seat 10 is fixed to the bottom of the top plate 9 by screws. An electric telescopic rod 12 is installed at the bottom of the fixing seat 10. A second discharge guide rail 14 is installed on one side of the top of the side panel 3 along the inclined direction.

[0023] After pouring the steel balls to be screened into the grooves of the bottom fixing plate 7 and screening plate 4, the steel balls are arranged in a row and the top plate 9 is continuously lifted by the electric telescopic rod 12 at the bottom, so that the steel balls can be gradually raised for processing. At this time, with the rectangular screening troughs 6 of different diameters, steel balls of different diameters can be quickly introduced to complete the grading and screening process. The size of the rectangular screening troughs 6 increases from bottom to top, so that the diameter of the screened steel balls increases step by step, which is convenient for later collection.

[0024] A rectangular screening groove 6 is opened through the top side of the inclined guide groove 5, and the width of the rectangular screening groove 6 gradually increases from bottom to top. The width of the rectangular screening groove 6 is adapted to the diameter of the steel ball. The fixed base 10 is provided with equally spaced gap slots 11, and the inner wall size of the gap slots 11 is adapted to the width of the screening plate 4.

[0025] The outer wall of one side of the side panel 3 has rectangular slots that are evenly distributed along the inclined direction, and the inner wall size of the rectangular slots is adapted to the inner wall width of the inclined guide groove 5. The inner wall of the rectangular slots is fixedly installed with a first discharge guide rail 13.

[0026] The top outer walls of both the screening plate 4 and the top plate 9 are inclined at an angle of 45 degrees.

[0027] After the steel balls are graded and screened and fall into the inclined guide trough 5, the inclined angle inside, combined with the effect of gravity, allows the steel balls to roll down quickly and avoid accumulating inside the inclined guide trough 5 for a long time. In addition, the bottom fixed seat 10 has L-shaped limit rods 16 on both sides that slide and insert continuously, which makes the top plate 9 more stable during the reciprocating motion.

[0028] In this embodiment, the grading and screening device is first assembled. After assembly, it is connected to an external power source for trial operation. Once the operation is normal, the steel balls to be screened are poured onto the guide plate 8. The steel balls will then roll into the gap between the fixed plate 7 and the bottom screening plate 4. After the steel balls are arranged in a row, the electric telescopic rod 12 is retracted to lower the top plate 9. When the top of the top plate 9 is lowered to the same inclined plane as the bottom of the lowest screening plate 4, the steel balls will roll to the lowest point of the top plate 9. At this time, the electric telescopic rod 12 is used to lower the top plate 9. As the top plate 9 moves upward, when the steel balls move to the rectangular screening trough 6, steel balls smaller than the rectangular screening trough 6 will roll directly into the interior and fall into the inclined guide trough 5. The remaining larger steel balls will push onto the next screening plate 4. Then the top plate 9 will rise and fall again. In conjunction with the rectangular screening troughs 6 of different diameters, steel balls of different sizes will be classified and screened. The steel balls that fall into the inclined guide trough 5 will be discharged from the first discharge guide rail 13 on the side, and the largest steel balls will be discharged from the second discharge guide rail 14 at the top.

[0029] Example 2:

[0030] A steel ball grading and screening device, such as Figure 1-3 As shown, this embodiment makes the following additions based on embodiment 1: the bottom outer wall of the side panel 3 is welded with symmetrically distributed limiting rings 15, and the outer walls of both sides of the fixing seat 10 are welded with L-shaped limiting rods 16, which are slidably inserted into the inner wall of the limiting rings 15.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
