[0001] The utility model relates to the technical field of vacuum sintering machines, in particular to a vacuum sintering machine with a tray module. Background Art

[0002] A vacuum sintering machine is a furnace that performs protective sintering on heated products in a vacuum environment. It often uses the principle of medium-frequency induction heating to sinter various metal powder compacts.

[0003] The production process of ring-shaped parts mainly includes mixing, stamping and sintering, which can process the powdered raw materials into ring shapes. The vacuum sintering machine is an indispensable part of the sintering process. However, the sintering chamber of the vacuum sintering machine currently used is located at a high position, and the number of parts that need to be sintered in each batch is large. The workers have to repeatedly take the ring-shaped parts and place the storage rack into the sintering chamber, which is labor-intensive.

[0004] In addition, the existing multi-layer simple storage racks easily cause the annular components to contact each other, which will lead to mutual adhesion after sintering, and will also affect the uniformity of heating of the annular components, thereby reducing the qualified rate of the annular components sintering.

[0005] Therefore, in order to solve the above problems, a vacuum sintering machine with a tray module is proposed. Utility Model Content

[0012] Furthermore, the distribution rod is tilted, and the front end of the distribution rod is higher than the rear end.

[0013] Furthermore, grooves are evenly formed on the upper side of the uniform distribution rod.

[0014] Furthermore, the drive assembly includes a double-groove winding wheel and a reduction motor.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 The utility model provides a vacuum sintering machine with a tray module, including a vacuum sintering machine body 1 and a cover 4. The main structure of the vacuum sintering machine body 1 includes a furnace body, an induction heating element, a vacuum pumping component, a water cooling and a control panel, etc. The vacuum sintering machine body 1 and the cover 4 are existing equipment. The cover 4 also has a handle and a locking handle to facilitate the pulling out and buckling and locking of the cover 4. The above is the existing technology and will not be repeated here.

[0027] Linear guide rails 2 are fixedly installed on the front and rear sides of the vacuum sintering machine body 1, and the slides of the linear guide rails 2 are fixedly installed with guide sleeves 7. The linear guide rails 2 are vertically arranged and the guide sleeves 7 are horizontally arranged. The guide sleeves 7 are slidably installed with polished rods 6, and the right end of the polished rod 6 is fixedly assembled with the cover 4; so that the cover 4 can move back and forth horizontally along the guide sleeve 7 through the polished rod 6, and the guide sleeve 7 can carry the polished rod 6 and the cover 4 to move back and forth vertically along the linear guide rail 2.

[0028] The left end of the polished rod 6 is also provided with a retaining spring through the annular groove to prevent it from falling out of the guide sleeve 7 and to play a role of position limiting protection.

[0029] A support base 3 is fixedly installed on the bottom left side of the cover 4, and a tray module 5 is placed on the upper side of the support base 3. The tray module 5 can be removed and used to store annular parts separately, which is convenient for use in the stamping process, or installed on the support base 3 for the sintering process to avoid frequent taking; a drive assembly 8 for lifting the guide sleeve 7 is installed on the upper side of the vacuum sintering machine body 1, and the drive assembly 8 is used to provide power for the guide sleeve 7 to lift and move.

[0030] Specifically:

[0031] like Figure 2 As shown, the support seat 3 includes a positioning rod 31 and a base 32. The right end of the base 32 is fixedly assembled with the cover 4, and multiple pairs of positioning rods 31 are evenly fixedly installed on the upper side of the base 32; the base 32 plays a major supporting role, while the positioning rods 31 on both sides are used for auxiliary support to ensure that the installed tray module 5 can be in a vertical state and will not move.

[0032] The positioning rod 31 is in a wedge shape that is narrow at the top and wide at the bottom, so as to improve the convenience and accuracy of installing the tray module 5 .

[0033] like Figure 3 As shown, the tray module 5 includes a tray 52 and a uniform distribution rod 55. Positioning grooves 51 matching the positioning rods 31 are provided at the bottom of the front and rear sides of the tray 52. ​​The positioning rods 31 are plugged into the positioning grooves 51 to facilitate the installation and removal of the tray 52. ​​A U-shaped frame 53 is evenly fixed on the front side of the tray 52. ​​The U-shaped frame 53 is plugged with a hinge piece 54 to facilitate the installation and removal of the hinge piece 54.

[0034] The front side of the link 54 is fixed with a uniform distribution rod 55, which is against the upper side of the U-shaped frame 53. After stamping, the annular components can be placed on each uniform distribution rod 55 for storage. During sintering, the uniform distribution rod 55 can also be used to evenly place the annular components.

[0035] The uniform distribution rod 55 is set at an angle, and the front end of the uniform distribution rod 55 is higher than the rear end; in order to prevent the annular components from falling off the uniform distribution rod 55 during sintering, grooves 56 are evenly opened on the upper side of the uniform distribution rod 55. Each annular component can be moved into the groove 56 and placed, maintaining a gap between each other, which is conducive to preventing them from sticking to each other during sintering.

[0036] like Figure 4 As shown, the driving assembly 8 includes a double-groove winding wheel 81 and a reduction motor 82. The reduction motor 82 is fixedly installed on the upper side of the vacuum sintering machine body 1, and the double-groove winding wheel 81 is installed on the circumferential side of the output end of the reduction motor 82. One end of a steel cable 84 is fixedly installed in each annular groove of the double-groove winding wheel 81, and the other end of the steel cable 84 is fixedly assembled with the guide sleeve 7 on the same side; when the reduction motor 82 is working, the double-groove winding wheel 81 can be rotated forward and reverse, thereby winding or releasing the two steel cables 84 at the same time to achieve the purpose of lifting and lowering the guide sleeve 7.

[0037] The reduction motor 82 is an existing component composed of a reducer, a servo motor with an encoder and other structures. It achieves precise control of the number of rotations through a closed-loop feedback system and precise pulse control. It rotates the same number of turns each time it is powered on, so that the guide sleeve 7 can move to the top or bottom along the linear guide rail 2.

[0038] A bearing seat 85 is fixedly installed on the upper side of the vacuum sintering machine body 1. The output end of the reduction motor 82 is rotatably assembled with the bearing seat 85. The bearing seat 85 can support the output end of the reduction motor 82, thereby improving the radial force bearing capacity of the output end of the reduction motor 82.

[0039] Rollers 83 are rotatably installed on the top of the front and rear sides of the vacuum sintering machine body 1. The rollers 83 are in contact with the steel cables 84. When the steel cables 84 are retracted or extended, they can move along the rollers 83, changing the conveying direction to make the movement smoother while also preventing the steel cables 84 and the vacuum sintering machine body 1 from scratching and damaging each other.

[0040] The reduction motor 82 is electrically connected to the control panel of the vacuum sintering machine body 1 , and the rotation direction of the output end of the reduction motor 82 is controlled by buttons on the control panel.

[0041] The working principle of this embodiment is as follows:

[0042] First, use the tray module 5 alone, and place the tray 52 horizontally on the turnover vehicle to facilitate transfer between the stamping and sintering processes. Each uniform distribution rod 55 can be removed through the hinge 54 and placed on the processing platform for collecting annular parts. After completion, the hinge 54 is installed into the U-shaped frame 53 by plugging. After all the uniform distribution rods 55 are collected and installed on the tray 52, they can be transferred to the sintering station.

[0043] First unlock and pull out the cover 4 by locking the handle, then control the driving component 8 to lower the guide sleeve 7 to the low position, so that the tray 52 can be placed vertically by plugging the positioning rod 31 into the positioning groove 51, and move the annular components until they are evenly distributed in the groove 56. The guide sleeve 7 is lifted back to the high position by the driving component 8, and the cover 4 is pushed back and locked. The tray module 5 can be driven into the sintering chamber of the vacuum sintering machine body 1. After the sintering of the vacuum sintering machine body 1 is completed, all of them can be taken out and placed on the turnover vehicle.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
