Description

A device that uses external airflow to improve the distribution of shot material along the width of the blade

technical field

The utility model relates to the fields of shot blasting cleaning, strengthening and forming, in particular to a device for improving the distribution of shot material along the blade width direction by using an external air flow.

Background technique

At present, the shot blasting tube of the shot blasting machine only has the feeding port. The shot material enters the shot tube from the feed port, flows along the inner wall of the shot tube under the action of gravity, and finally gathers on the side of the shot wheel away from the shot tube. The shot beam has a continuous impact on the root of the side of the shot wheel, which makes the root of the side of the shot wheel wear too fast, resulting in early wear and failure of the shot wheel. Moreover, the pellets that have not been fully dispersed fly out of the window of the directional sleeve after being accelerated by the shot separating wheel, and then are taken over by the blades, resulting in the excessive erosion and wear of the corresponding parts of the window of the directional sleeve and the blades, resulting in premature wear and failure, and a significant shortening Consumable life. In addition, the impact range of the shot concentrated on one side to the processed workpiece is obviously smaller than that of the shot dispersed. That is to say, the current shot blasting tube structure causes: 1. Premature failure of the blast wheel, directional sleeve and blades, etc.; 2. Reduces the working efficiency of the shot blaster.

Contents of the invention

The technical problem to be solved in this patent is: use the external air flow to disperse the concentrated shot, so as to improve the distribution of the shot along the width direction of the blade, and finally solve the above-mentioned problems in the background technology.

In order to achieve the above purpose, this patent provides the following technical solutions:

A device for improving the distribution of shot material along the blade width direction by using an external air flow, characterized in that it includes a shot blaster bottom plate (14) fixed in the shot blasting chamber, and a shot blaster is installed on the shot blaster bottom plate (14) The shell (2) and the bearing seat (13), the shell (2) is connected with the cover (1), and the inside of the shot blasting machine shell (2) is connected with the side guard plate (3) by bolts. connection, the upper end of the side guard (3) is equipped with a top guard (10), the right end of the housing (2) is connected with the front cover (5) by bolts, the left end of the housing (2) Connected with the rear cover (11) by screws, the main shaft (15) is installed inside the bearing seat (13), the right end of the main shaft (15) is connected with the linkage plate (12), and the linkage plate (12) is connected with the branch The pill wheel (7) is connected, the linkage disc (12) is connected with the impeller II (16) through the screw, and the impeller II (16) is connected with the impeller I (9) through the pin shaft (17). The impeller II (16) and the impeller I (9) are connected to the blades (4), the front cover (5) is connected to the orientation sleeve (8), and the orientation sleeve (8) is connected to the shot pipe (6) Connect, the upper end of the shot pipe (6) is the feed inlet, and the right side is the air supply outlet.

Compared with the prior art, the beneficial effects of this patent are mainly reflected in:

The problem existing in the shot blasting machine at present is that the shot material in the shot blasting tube is concentrated on the side of the shot wheel far away from the shot blasting tube under the action of gravity (at this time, the influence of air on the shot material is negligible), resulting in the shot blasting on this side. The wheel wears too quickly, and further causes the orientation sleeve and blade on the same side to also be worn out too quickly and fail.

A supplementary air inlet is added to the wall of the shot blasting tube of the shot blasting machine, and compressed air is blown inward from the supplementary air port. When filling the air port, the shot material is not only affected by its gravity, but also affected by the additional air flow. The high-speed moving air blows the shot material apart, so that the shot material is more evenly distributed in the axial direction of the shot wheel; this reduces the The impact and wear of the shot on the side of the shot wheel away from the shot tube delays the wear and tear failure time of the shot wheel, and further reduces the concentration of wear on the directional sleeve and blades on the same side; the shot accelerated by the shot wheel The material is received by the blade more dispersedly through the window of the directional sleeve.

detailed description

The technical solutions in this patent will be clearly and completely described below in conjunction with accompanying drawings 1 to 7 in the embodiments of this patent. Apparently, the described embodiments are only some of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of this patent.

With reference to accompanying drawing 1 to accompanying drawing 7, the utility model provides a kind of equipment that utilizes the external air flow to improve the distribution of shot material along the width direction of the blade: including the shot blasting device bottom plate (14) fixed in the shot blasting chamber, the shot blasting device bottom plate (14) is equipped with a shot blasting machine shell (2) and a bearing seat (13), the shell (2) is connected with the cover (1), and the inside of the shot blasting machine shell (2) passes through The bolts are connected with the side guards (3), the upper end of the side guards (3) is equipped with a top guard (10), the right end of the housing (2) is connected with the front cover (5) by bolts, The left end of the housing (2) is connected to the rear cover (11) through screws, the main shaft (15) is installed inside the bearing seat (13), and the right end of the main shaft (15) is connected to the linkage plate (12). The linkage disc (12) is connected with the shot wheel (7), the linkage disc (12) is connected with the impeller II (16) through a screw, and the impeller II (16) is connected with the impeller through a pin shaft (17) I (9) is connected, the impeller II (16) and impeller I (9) are connected with the blade (4), the front cover (5) is connected with the orientation sleeve (8), and the orientation sleeve (8 ) is connected with the shot pipe (6), the upper end of the shot pipe (6) is the feed inlet, and the right side is the air supply port.

As shown in Figure 3, the shot material enters through the feed inlet at the upper end of the shot tube (6), and the air supply port on the right side of the shot tube (6) is connected to the air source for supplementary air, and the increased wind force of the air source will flow in.
