Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a shot blasting machine for steelmaking. Background Technology

[0002] In metal processing procedures such as casting, forging, and welding, various impurities such as oxide scale, rust, welding slag, and burrs inevitably accumulate on the surface of workpieces. The presence of these impurities significantly impacts subsequent processing steps and the quality of the final product. Shot blasting machines, as highly efficient surface treatment equipment, can effectively remove these impurities from workpiece surfaces, achieving specific cleanliness and roughness standards. This creates favorable surface conditions for subsequent machining, painting, and electroplating processes, ensuring the smooth operation of these processes and the stability of product quality.

[0003] However, existing steel workpieces also require shot blasting after completing the machining process. But steel workpieces come in a variety of shapes, including plates, tubes, and spheres. Different types of shot blasting machines must be used to process workpieces of different shapes. This is because different shapes of workpieces differ significantly in clamping methods and shot blasting path planning. A single type of shot blasting machine cannot effectively clamp and blast workpieces of various shapes, thus failing to meet diverse processing needs. Utility Model Content

[0004] The purpose of this invention is to provide a shot blasting machine for steelmaking to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting machine for steelmaking, comprising a shot blasting chamber and a shot blasting machine body, wherein the output end of the shot blasting machine body is connected to the top of the shot blasting chamber, a door is hinged to the opening end of the shot blasting chamber, a rotating assembly is provided on the inner side wall of the shot blasting chamber, and mounting plates are symmetrically provided on the rotating assembly through a mounting mechanism, and electric push rods are provided on the side walls of the two mounting plates that are close to each other, and a clamping assembly is provided at the output end of the electric push rods.

[0010] Preferably, the clamping assembly is an adjusting plate connected to the output end of the electric push rod. The adjusting plate has a clamping column on its side wall away from the electric push rod, and the clamping column has an anti-slip sleeve on its circumferential side.

[0011] Preferably, the clamping assembly is an arc-shaped clamping plate connected to the output end of the electric push rod, and anti-slip parts are provided at equal intervals on the inner arc surface of the arc-shaped clamping plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1-3 This utility model provides an embodiment of a shot blasting machine for steelmaking, comprising a shot blasting chamber 11 and a shot blasting machine body 12. The output end of the shot blasting machine body 12 is connected to the top of the shot blasting chamber 11. The shot blasting machine body 12 is mainly equipped with a shot circulation system, a bottom screw conveyor to collect scattered shot, and a bucket elevator to transport it to a sorter. The dust removal system can use a bag filter or a filter cartridge dust removal device, which can facilitate shot blasting of steel workpieces. The shot blasting chamber 11 has a hinged door 13 at the open end for easy opening and closing, and for easy placement and removal of workpieces. The inner side wall of the shot blasting chamber 11 is provided with a rotating assembly. The rotating assembly is symmetrically provided with mounting plates 31 through a mounting mechanism. Electric push rods are provided on the side walls of the two mounting plates 31 that are close to each other. The output end of the electric push rod is provided with a clamping assembly.

[0024] To facilitate clamping and fixing of steel workpieces, and to select appropriate clamping components according to the shape of the workpiece to ensure clamping effect without affecting shot blasting, a rotating assembly is provided on the inner side wall of the shot blasting chamber 11. The rotating assembly includes rotating shafts 23 symmetrically arranged on the side wall of the shot blasting chamber 11. One end of one rotating shaft 23 protrudes from the shot blasting chamber 11 and is fixedly connected to the output end of the motor 21 via a coupling. The motor 21 is fixedly connected to the outer side wall of the shot blasting chamber 11 via a fixing seat 22 to ensure the stability and firmness of the motor 21. To facilitate installation and disassembly, and for easy maintenance or replacement, the mounting mechanism includes the insertion of the two rotating shafts 23 close to each other at their ends. The plug-in block 32 has a plug-in plate 33 on its outside. The plug-in plate 33 has a plug-in groove for easy insertion of the plug-in block 32. The plug-in plate 33 is fixedly connected to the mounting plate 31. The mounting mechanism also includes sliding cavities 53 that are equidistantly opened inside the plug-in block 32. A moving plate 55 is connected to the sliding cavity 53 by a spring 54. A positioning member 52 is welded to the end of the moving plate 55 away from the spring 54. The positioning member 52 slides out of the sliding cavity 53. The side wall of the plug-in plate 33 has a positioning hole 51 that matches the sliding cavity 53. The positioning hole 51 and the positioning member 52 can position and fix the plug-in plate 33 and the plug-in block 32 after insertion, ensuring stability and firmness.

[0025] To facilitate clamping and fixing of steel plate workpieces and to facilitate polishing operations, such as Figure 2 As shown, the clamping assembly is a clamping block 41 connected to the output end of the electric push rod. Anti-slip protrusions 42 are provided at equal intervals on the side wall of the clamping block 41 away from the electric push rod. The clamping block 41 can clamp and fix the two side walls of the steel plate by cooperating with the anti-slip protrusions 42. At the same time, it can rotate the whole machine in conjunction with the motor 21. The main body 12 of the shot blasting machine can work to perform shot blasting on the steel plate.

[0026] Example 2

[0027] Please see Figures 1-4 To facilitate clamping and fixing of steel round pipes and other materials, and to facilitate subsequent shot blasting, the clamping assembly is an adjusting plate 61 connected to the output end of an electric push rod. The adjusting plate 61 has a clamping post 63 on its side wall away from the electric push rod, and the clamping post 63 has an anti-slip sleeve 62 on its circumferential side. The clamping post 63 and the anti-slip sleeve 62 can be frustoconical to accommodate steel round pipes of different diameters.

[0028] Example 3

[0029] Please see Figures 1-3 and Figure 5As shown, in order to facilitate the clamping and fixing of steel spherical workpieces and ensure the shot blasting effect, the clamping assembly is an arc-shaped clamping plate 71 connected to the output end of the electric push rod. Anti-slip parts 72 are provided at equal intervals on the inner arc surface of the arc-shaped clamping plate 71. The anti-slip parts 72 are spherical in shape, which reduces the contact area with the steel spherical workpiece and does not affect the shot blasting process.

[0030] The clamping assembly can also be in other shapes, depending on the shape of the steel workpiece to be processed, to ensure the clamping effect on the workpiece without affecting the shot blasting process.

[0031] In use, select the appropriate clamping assembly, press the positioning piece 52, and slide the moving plate 55 within the sliding cavity 53. The spring 54 contracts to store potential energy, and the positioning piece 52 enters the sliding cavity 53. At this time, insert the connecting plate 33 and the connecting block 32. After insertion and positioning, the positioning piece 52 aligns with the positioning hole 51. Under the action of the potential energy of the spring 54, the positioning piece 52 is reset and moved, and then the positioning piece 52 enters the positioning hole 51, which can position and fix the connecting plate 33 and the connecting block 32. Then, place the workpiece to be shot-blasted between the two clamping assemblies. The electric push rod extends, moving the clamping assemblies to clamp and fix the workpiece. Then, the motor 21 works, moving the rotating shaft... 23 rotates, and the workpiece rotates accordingly. The main body 12 of the shot blasting machine works and can perform shot blasting on the workpiece. After the processing is completed, the electric push rod retracts, moving and resetting the clamping assembly, thus losing the clamping fixation on the workpiece, making it easy to remove and complete the processing. When it is necessary to replace the clamping assembly, by pressing the positioning part 52, the moving plate 55 slides in the sliding cavity 53. The spring 54 contracts and stores potential energy, and the positioning part 52 enters the sliding cavity 53. At this time, it loses the positioning fixation on the plug plate 33 and the plug block 32. The plug plate 33 can be removed from the plug block 32 to complete the disassembly. Then, select a suitable clamping assembly and repeat the above operation to complete the installation and clamp the suitable workpiece for shot blasting.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
