Description
Technical Field
[0001] This utility model relates to the field of screening technology, and in particular to a gravity-type shot peening particle screening device. Background Technology
[0002] A shot peening machine is a device that uses a high-speed stream of shot to impact a metal surface. When shot peening a workpiece, the impact of the shot causes plastic deformation on the workpiece surface, forming a certain compressive stress layer, thereby improving reliability and durability. However, uneven shot particle size can lead to inconsistent shot peening effects, affecting the quality and uniformity of surface treatment. Therefore, the particle size of the shot needs to be screened.
[0003] Shot peening particles are screened to separate large and small particles. The appropriate screen needs to be selected according to the size range of the shot peening particles and the screening requirements to obtain particles of the required size for use as raw materials for shot peening machines.
[0004] However, when screening shot peening particles, the mesh size of this type of screen becomes clogged by the shot peening particles, which affects the flow of small shot peening particles and reduces the screening efficiency of the screen. Utility Model Content
[0005] The purpose of this invention is to address the problem in the prior art where the screen aperture is blocked by shot peening particles, resulting in reduced screening efficiency, and to propose a gravity-type shot peening particle screening device.
[0006] The technical solution of this utility model is: a gravity shot peening particle screening device, comprising: a housing, an inclined screen rotatably connected to the middle of the housing, and a small particle bin opened on the inner wall of the housing below the screen.
[0007] The anti-clogging component includes a vibration spring, a slider, a support cylinder, a positioning spring plate, and a plug rod. The top of the vibration spring is elastically connected to the screen, and the bottom of the vibration spring is fixedly installed with the slider. The slider slides up and down on the inner wall of the support cylinder. The positioning spring plate is fixedly installed on the inner wall of the support cylinder below the slider, and the plug rod is fixedly installed on the inner wall of the machine housing.
[0008] The support cylinder is fixedly installed on the inner wall of the machine housing, and the insertion rod is located on the rotation path of the screen holes on the screen.
[0009] Optionally, the bottom of the slider adopts a frustum-shaped structure, the positioning spring is inclined, and the inclined surface of the positioning spring contacts the slider.
[0010] Optionally, a triangular prism is fixedly installed at the bottom of the insertion rod. Multiple insertion rods are provided and are distributed equidistantly along the triangular prism in a straight line. Both ends of the triangular prism are fixedly connected to the housing, and the bottom surface of the triangular prism is parallel to the horizontal plane.
[0011] Optionally, a stop block is fixedly installed on the top of the vibration spring. The stop block has a hemispherical structure and slides on the bottom of the screen. A telescopic rod is fixedly installed on the bottom of the stop block. The bottom of the telescopic rod is fixedly connected to the slider. A return spring is elastically connected between the bottom of the slider and the support cylinder.
[0012] Optionally, the inner wall of the support cylinder is provided with two symmetrically arranged clearance grooves, and the end of the positioning spring sheet is fixedly installed in the clearance groove.
[0013] Optionally, a shielding assembly is also included, which includes a baffle and a non-woven fabric sheet. The baffle is fixedly installed on the top of the screen and on both the front and rear sides, and the non-woven fabric sheet is fixedly installed on the left end of the screen.

[0016] Compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0017] In this invention, when the weight of the screen and the shot peening particles is greater than the supporting force of the positioning spring on the slider, it indicates that the shot peening particles accumulate on the screen, causing the slider to break through the restriction of the positioning spring, increasing the rotation range of the screen. The screen rotates under the action of gravity, causing the insert rod to be inserted into the screen hole of the screen, squeezing out the shot peening particles in the screen hole, thus preventing the shot peening particles from clogging the screen and affecting the screening of the shot peening particles.

[0029] Example 1
[0030] This embodiment proposes a gravity-type shot peening particle screening device, such as... Figure 1 As shown, the system includes a housing 1, with an inclined screen 2 rotatably connected to the center of the housing 1. A feed pipe is fixedly installed on the right side of the housing 1. Rotating shafts are fixedly installed on both the front and rear sides of the screen 2, near its left end. The screen 2 is rotatably connected to the housing 1 via the rotating shafts. Shot peening particles flow through the feed pipe and are pressed against the right end of the screen 2.
[0031] like Figure 1 and Figure 2 As shown, a large particle chamber 3 is located at the top of the casing 1 and at the left end of the screen 2, and a small particle chamber 4 is located on the inner wall of the casing 1 and below the screen 2. The large particle chamber 3 is used to collect large shot peening particles, and the small particle chamber 4 is used to collect small shot peening particles.
[0032] like Figure 2 and 3 As shown, an anti-clogging component 5 is provided on the inner wall of the housing 1 and below the screen 2. The anti-clogging component 5 includes a vibration spring 51, a slider 53, a support cylinder 55, a positioning spring plate 56, and a plug rod 58. The top of the vibration spring 51 is elastically connected to the screen 2, the bottom of the vibration spring 51 is fixedly installed with the slider 53, and the top of the vibration spring 51 is fixedly installed with a stop block 52. The stop block 52 adopts a hemispherical structure and slides at the bottom of the screen 2.
[0033] The abutment block 52 replaces the vibration spring 51 and is connected to the screen 2 to prevent the vibration spring 51 from being squeezed and bent when the screen 2 rotates. A telescopic rod 54 is fixedly installed at the bottom of the abutment block 52. The bottom of the telescopic rod 54 is fixedly connected to the slider 53. The telescopic rod 54 guides the movement path of the abutment block 52 to prevent the abutment block 52 from bending.
[0034] like Figure 3 As shown, the slider 53 slides up and down on the inner wall of the support cylinder 55. The support cylinder 55 is fixedly installed on the inner wall of the housing 1. The positioning spring plate 56 is fixedly installed on the inner wall of the support cylinder 55 and below the slider 53. The bottom of the slider 53 adopts a frustum-shaped structure. The positioning spring plate 56 is inclined and the inclined surface of the positioning spring plate 56 contacts the slider 53 so that the slider 53 can squeeze the positioning spring plate 56.
[0035] The positioning spring plate 56 supports the slider 53 and restricts the position of the slider 53. When the flow rate of the screen mesh 2 is normal, shot peening particles will not accumulate on the screen mesh 2. The shot peening particles in the feed pipe fall from a height onto the screen mesh 2. The gravitational potential energy of the shot peening particles presses down on the screen mesh 2 and compresses the vibration spring 51. Through the elastic force of the vibration spring 51 and the gravitational potential energy of the shot peening particles, the screen mesh 2 resets after rotation, thereby causing the screen mesh 2 to vibrate.
[0036] like Figure 3 As shown, the insertion rod 58 is fixedly installed on the inner wall of the housing 1. A triangular prism is fixedly installed at the bottom of the insertion rod 58. Multiple insertion rods 58 are arranged and are distributed equidistantly along the triangular prism in a straight line. Both ends of the triangular prism are fixedly connected to the housing 1, and the bottom surface of the triangular prism is parallel to the horizontal plane. The insertion rod 58 is located on the rotation path of the screen holes on the screen 2. A return spring 57 is elastically connected between the bottom of the slider 53 and the support cylinder 55.
[0037] When the sieve holes of screen 2 are blocked and the flow rate of screen 2 is reduced, the shot peening particles in the sieve holes prevent small shot peening particles from falling down from screen 2. At the same time, the shot peening particles in the sieve holes of screen 2 prevent large shot peening particles from moving to the left end of screen 2, resulting in the accumulation of shot peening particles.
[0038] When the weight of the screen 2 and the shot peening particles is greater than the supporting force of the positioning spring plate 56 on the slider 53, it indicates that shot peening particles accumulate on the screen 2. At this time, the positioning spring plate 56 deforms and bends. The slider 53 moves downward and compresses the return spring 57. At this time, the right end of the screen 2 is unsupported, and the screen 2 breaks through the limitation of the rotation angle. The screen 2 rotates and contacts the insertion rod 58. The insertion rod 58 is inserted into the screen hole of the screen 2, squeezing out the shot peening particles in the screen hole of the screen 2, thereby restoring the screening function of the screen 2. Under the action of the screening function of the screen 2, the small shot peening particles accumulated on the screen 2 fall from the screen hole of the screen 2, and the large shot peening particles flow into the large particle bin 3 along the screen 2. The elastic force of the return spring 57 lifts the screen 2.
[0039] The inner wall of the support cylinder 55 has two symmetrically arranged clearance grooves, and the end of the positioning spring plate 56 is fixedly installed in the clearance groove. The positioning spring plate 56 bends and retracts completely into the clearance groove, reducing obstruction to the slider 53.
[0040] In this embodiment, when the weight of the screen 2 and the shot peening particles is greater than the supporting force of the positioning spring plate 56 on the slider 53, it indicates that the shot peening particles accumulate on the screen 2, causing the slider 53 to break through the restriction of the positioning spring plate 56, increasing the rotation range of the screen 2. The screen 2 rotates under the action of gravity, causing the insertion rod 58 to be inserted into the screen hole of the screen 2, squeezing out the shot peening particles in the screen hole of the screen 2, so that the screen 2 can work normally.
[0041] Example 2
[0042] Based on Example 1, this example proposes a gravity-type shot peening particle screening device, such as... Figure 1 As shown, it also includes a shielding assembly 6, which includes a baffle 61 and a non-woven fabric sheet 62. The baffle 61 is fixedly installed on the top of the screen 2 and on both the front and rear sides, and the non-woven fabric sheet 62 is fixedly installed on the left end of the screen 2. The baffle 61 and the non-woven fabric sheet 62 prevent shot peening particles on the screen 2 from falling off the screen 2.
[0043] like Figure 1 and Figure 2 As shown, a ramp 63 is fixedly installed on the top of the housing 1 and at the end of the screen 2. A non-woven fabric sheet 62 is pasted on the top of the ramp 63. The ramp 63 and the non-woven fabric sheet 62 guide the flow of shot peening particles on the screen 2.
[0044] In this embodiment, the inclined platform 63 puts the non-woven fabric sheet 62 in an inclined state. The non-woven fabric sheet 62 serves as an extension of the screen 2 to feed large shot peening particles into the screen 2. The baffle 61 and the non-woven fabric sheet 62 cover the gap between the screen 2 and the machine casing 1 to prevent shot peening particles from falling.
[0045] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
