Problems solved by technology

[0004] In the existing powder plate rolling and compounding process, the powder spreading process usually uses a roller or a scraper to spread the powder manually, which has the following problems: 1) Metal powder is easy to be picked up when the roller rolls, resulting in loose powder and powder spreading. Inhomogeneous; 2), scraping strip scraping powder is easy to produce scratches
Both will reduce the spreading effect

Embodiment 1

[0038] Such as Figure 1 to Figure 5 As shown, a fast powder spreading device for powder plate rolling and compounding includes a frame 5, a powder spreading device, a vibrating motor 8, a driving device and a control device. The powder spreading device is used for filling powder and discharging powder, and spreading The duster is set above the metal plate and is slidably connected to the frame 5. There is a powder outlet at the bottom of the powder spreader. The vibration motor 8 is fixedly connected to the powder spreader. The vibration motor 8 is provided with a frequency modulation switch. connection, the frequency modulation switch controls the vibration frequency of the vibrating motor 8, the powder in the powder spreader can be dispersed evenly by vibrating the powder spreader, and the powder flows out from the powder outlet and spreads on the metal plate automatically, avoiding the The uneven distribution of powder during the powder spreading process causes the problem...

Embodiment 2

[0041] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0042] Such as Figure 1 to Figure 5 As shown, the driving device includes a motor and a lead screw 23, the motor is fixed to the frame 5, and the lead screw 23 is axially arranged parallel to the powder spreading direction. Usually, the powder spreading direction is consistent with the length direction of the metal plate. The powder spreader is provided with a nut matching the lead screw 23, one end of the lead screw 23 is connected to the output shaft of the motor, the other end of the lead screw 23 is screwed to the nut, the motor drives the lead screw 23 to rotate, and the lead screw 23 drives the nut to carry the powder The device moves linearly along the lead screw 23, so that the powder spreader can move linearly above the metal plate along the length direction of the metal plate.

[0043] In addition to the lead screw 23 and the nut, the transmission of the...

Embodiment 3

[0046] The structure of this embodiment is basically the same as that of Embodiment 2, the difference is that:

[0047] Such as Figure 1 to Figure 5 As shown, the frame 5 is provided with a powder spreading platform 31 for carrying metal plates. The length direction of the powder spreading platform 31 is parallel to the axial direction of the lead screw 23. The powder spreading platform 31 is located below the powder spreading device and is slidably connected to the powder spreading device. The setting of the powder spreading platform 31 enables the metal sheet to be placed under the powder spreading device evenly, which is conducive to meeting the accuracy requirements of powder spreading.

[0048] Specifically, linear guide rails are provided on both sides of the powder spreading platform 31, and the linear guide rails are arranged along the powder spreading direction, and the powder spreader slides linearly along the linear guide rails. The setting of the linear guide rail ...

Abstract

The invention relates to a rapid powder spreading device for powder plate rolling and compounding. The device comprises a frame, a powder spreader, a vibration motor, a driving device and a control device, wherein the powder spreader is arranged above a metal plate and connected to the frame in a sliding manner, a powder outlet is formed in the bottom of the powder spreader, the vibration motor isfixedly connected to the powder spreader, the vibration motor is provided with a frequency modulation switch, the frequency modulation switch is electrically connected with the vibration motor, the driving device is fixedly connected to the frame, the driving device drives the powder spreader to move linearly in the powder spreading direction, and the control device controls the driving device toact. The powder spreader is driven by the driving device to linearly move in the powder spreading direction, powder can be quickly and uniformly spread on the metal plate through the powder outlet, powder cannot be brought or scratched in the powder spreading process, and the powder spreading effect is good.

Description

technical field [0001] The invention relates to the field of sliding bearing bush processing, in particular to a fast powder spreading device for powder plate rolling and compounding. Background technique [0002] In the field of sliding bearing processing, in order to realize the effective combination of the alloy layer and the metal plate, it is necessary to prepare a bimetallic bearing strip with excellent performance. At present, the common preparation methods mainly include casting method, pressure processing method and powder plate rolling compound method. [0003] The powder plate rolling composite method is a means of spreading the bearing alloy powder on the pre-treated metal plate, and obtaining the tight combination of the alloy powder and the metal plate through rolling and sintering. [0004] In the existing powder plate rolling and compounding process, the powder spreading process usually uses a roller or a scraper to spread the powder manually, which has the ...
