Description

Technical Field

[0001] This utility model relates to the technical field of shot blasting of pipe fittings, and in particular to a shot blasting machine for round pipe workpieces. Background Technology

[0002] A shot blasting machine is a machine that uses a high-speed rotating shot blaster to propel abrasive materials such as steel shot and steel grit onto the surface of metal workpieces (e.g., castings, metal pipes, structural parts) to perform cleaning, rust removal, and oxide scale removal.

[0003] In the shot blasting process of round pipe fittings, the pipe fittings pass through the shot blasting machine at a constant speed under the action of external conveying equipment to complete the surface treatment process. However, in the above processing steps, the round pipe fittings move in a horizontal arrangement, and the shot inside the shot blasting machine can easily enter the round pipe fittings through the open pipe opening, causing the shot to be placed outside the equipment, increasing the number of subsequent processing steps. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a shot blasting machine for round tube workpieces, which tilts the tube during the shot blasting process through a support component to prevent shot particles from remaining inside the tube.

[0006] To achieve the above objectives, this utility model proposes a shot blasting machine for round tube workpieces, comprising a base, a protective box, a shot blasting assembly, a support assembly, and a conveying assembly. The protective box is fixedly connected to the upper end of the base. The shot blasting assembly is disposed inside the protective box. The support assembly includes a support block, a lifting device, a roller frame, and a support rod. The support block is positioned in front of and behind the protective box via the lifting device, which is located on the base. The roller frame is also positioned on the base via the lifting device. A positioning roller is rotatably connected inside the roller frame. A first driving member is mounted on the roller frame, and the output shaft of the first driving member is connected to the positioning roller. The support rod is located on one side of the roller frame, and the conveying assembly is located above the base.

[0007] In addition, the shot blasting machine for round tube workpieces proposed above according to this utility model may also have the following additional technical features: Specifically, the shot blasting assembly includes a shot blasting machine and a baffle, wherein the shot blasting machine is disposed inside the protective box, and the baffle is disposed at the front and rear ends of the protective box.

[0008] Specifically, the lifting device includes a support frame and a second driving member. The support frame is located in front of the protective box and is fixedly connected to the base. The second driving member is telescopic and one end is fixedly connected to the support frame, and the other end of the second driving member is fixedly connected to the support block.

[0009] Specifically, a drive component is provided on the support block.

[0010] Specifically, the conveying assembly includes a conveying roller assembly and a third driving member. The conveying roller assembly is disposed in front of and behind the protective box and is rotatably connected to the base. The third driving member is disposed on one side of the conveying roller assembly and its output shaft is connected to the conveying roller assembly.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: In the round tube shot blasting machine of this utility model, the lifting device controls two positioning rollers to move downward. With the cooperation of the conveying component, the rear end of the tube is offset downward. The shot entering the rear end of the tube falls out of the tube due to its own gravity, preventing the shot from accumulating at the rear end of the tube. After the front end of the tube is separated from the front conveying component, the lifting device controls the two positioning rollers to move downward. With the cooperation of the conveying component, the front end of the tube is kept conveyed downward. The shot entering the front end of the tube falls out of the tube due to its own gravity, preventing the shot from being placed outside the device and reducing the need for additional shot cleaning steps.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following describes the shot blasting machine for round tube workpieces according to an embodiment of the present invention with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown, the round tube shot blasting machine of this utility model embodiment may include a base 1, a protective box 2, a shot blasting assembly 3, a support assembly 4, and a conveying assembly 5.

[0018] The protective box 2 is fixedly connected to the upper end of the base 1, the shot blasting assembly 3 is set inside the protective box 2, the support assembly 4 is installed on the base 1, and the conveying assembly 5 is set above the base 1.

[0019] It should be noted that the base 1 described in this embodiment is the supporting foundation of the entire device, used to support the protective box 2, shot blasting assembly 3, support assembly 4 and conveying assembly 5. The protective box 2 prevents shot from splashing during shot blasting. The pipe enters the protective box 2 from the front and is then sent out from the rear of the protective box 2. The conveying assembly 5 is used to transport the pipe into the protective box 2.

[0020] The support assembly 4 includes a support block 41, a lifting device 42, a roller frame 43, and a support rod 44.

[0021] Among them, the support block 41 is set at the front and rear of the protective box 2 through the lifting device 42, the lifting device 42 is set on the base 1, the roller frame 43 is set on the base 1 through the lifting device 42, the roller frame 43 is rotatably connected to the positioning roller 431, the upper end of the roller frame 43 is provided with the first driving member 432, the output shaft of the first driving member 432 is connected to the positioning roller 431, and the support rod 44 is set on one side of the roller frame 43.

[0022] It should be noted that the support block 41 described in this embodiment is installed above the base 1 and located on the front and rear sides of the protective box 2, and is used to provide a support base for the roller frame 43. The lifting device 42 is used to control the support block 41 to move up and down in a straight line, and drive the roller frame 43 and the positioning roller 431 to move up and down in a straight line synchronously through the support block 41. The outer side of the positioning roller 431 is an inwardly concave arc shape. The positioning roller 431 increases the contact area with the pipe through the arc-shaped roller surface. The two support rods 44 are respectively rotatably connected to the opposite side of the roller frame 43 through bearings. A limiting mechanism is installed at the connection between the support rods 44 and the roller frame 43 to control the rotatable angle of the roller frame 43.

[0023] The first driving component 432 is a servo motor, which drives the positioning roller 431 to rotate, and the rotating positioning roller 431 drives the tube to move.

[0024] Specifically, the lifting device 42 controls the support height of the two positioning rollers 431 to be flush with the conveying component 5, then places the pipe on the conveying component 5 and pushes the pipe backward. The rear end of the pipe moves between the two positioning rollers 431 under the support of the conveying component 5.

[0025] The first driving component 432 drives the positioning roller 431 to rotate. The pipe moves backward under the drive of the positioning roller 431 and the support of the conveying component 5. The pipe smoothly enters the protective box 2. The shot blasting component 3 sprays shot to blast the pipe. After the pipe has traveled a certain distance backward inside the protective box 2 (for example, to half of the travel distance inside the protective box 2), the lifting device 42 on the front side of the protective box 2 controls the support block 41 to move downward. The support block 41 drives the positioning roller 431 to move downward through the support rod 44 and the roller frame 43, tilting the rear end of the pipe downward synchronously. The height of the front conveying roller group 51 is adjusted synchronously to keep the pipe conveyed backward with the rear end lower and the front end higher. The shot that has entered the pipe slides out of the pipe under the action of gravity.

[0026] After the rear end of the pipe fitting is removed from the protective box 2, the lifting device 42 on the front side is raised, and the conveying roller group 51 on the front side is adjusted to a horizontal position to ensure that the rear end of the pipe fitting can move horizontally between the two positioning rollers 431 on the rear side. The first driving member 432 drives the positioning rollers 431 on the rear side to rotate, and the front and rear positioning rollers 431 continuously drive the pipe fitting to be conveyed smoothly to the rear.

[0027] When the front end of the pipe enters the protective box 2 and loses the support of the front positioning roller 431, the rear lifting device 42 controls the positioning roller 431 to descend, the front end of the pipe tilts downward, and the height of the rear conveying roller group 51 is adjusted synchronously to keep the pipe conveyed in a posture with the front end lower and the rear end higher, and the pellets that have entered the pipe slide out.

[0028] After the front end of the pipe fitting is completely removed from the protective box 2, the lifting device 42 on the rear side controls the positioning roller 431 to rise, and the conveying assembly 5 on the rear side returns to a horizontal state, and the pipe fitting is conveyed backward in a horizontal posture. The device is ready for the next shot blasting.

[0029] In one embodiment of this utility model, such as Figure 5 As shown, the shot blasting assembly 3 may include a shot blasting machine unit 31 and a baffle 32.

[0030] The shot blasting unit 31 is installed inside the protective box 2, and the baffle curtain 32 is installed at the front and rear ends of the protective box 2.

[0031] It should be noted that the shot blasting unit 31 described in this embodiment is used to propel shot at high speed onto the outer wall of the round tube workpiece to achieve outer wall cleaning, rust removal or surface strengthening. The baffle 32 is used to prevent shot from splashing out of the protective box 2, while allowing the round tube workpiece to pass freely.

[0032] In one embodiment of this utility model, such as Figure 5 As shown, the lifting device 42 may include a support frame 421 and a second drive member 422.

[0033] The support frame 421 is located in front of the protective box 2 and is fixedly connected to the base 1. The second driving member 422 is telescopic and one end is fixedly connected to the support frame 421, and the other end of the second driving member 422 is fixedly connected to the support block 41.

[0034] It should be noted that the support block 41 is slidably connected inside the support frame 421. The support frame 421 protects the second drive component 422 inside. The second drive component 422 drives the support block 41 to move downward in a stable linear motion under the restriction of the support frame 421, thereby controlling the height of the positioning roller 431. The positioning roller 431 controls the height of the end of the pipe.

[0035] It should be noted that the second driving component 422 proposed in the above embodiment is an electric telescopic rod, which directly drives the support block 41 to move up and down in the vertical direction through the telescopic action, thereby driving the positioning roller 431 to control the height of the end of the pipe.

[0036] In one embodiment of this utility model, such as Figure 5 As shown, a drive unit 6 can be installed on the support block 41.

[0037] Specifically, the driving component 6 includes guide blocks and adjusting screws. A groove is opened at the upper end of the support block 41, and two guide blocks are slidably connected inside the groove. The adjusting screw is rotatably connected inside the groove through a bearing. Both ends of the adjusting screw extend out of the support block 41 and form control ends. By rotating the adjusting screw through the control ends, the two guide blocks are driven to move closer or further apart. The guide blocks drive the support rod 44 and the roller frame 43 to move, thereby controlling the spacing of the positioning rollers 431.

[0038] In one embodiment of this utility model, such as Figure 1 As shown, the conveying assembly 5 may include a conveying roller set 51 and a third drive unit 52.

[0039] The conveyor roller assembly 51 is located in front of and behind the protective box 2. The conveyor roller assembly 51 is rotatably connected to the base 1. The third drive unit 52 is located on one side of the conveyor roller assembly 51. The output shaft of the third drive unit 52 is connected to the conveyor roller assembly 51.

[0040] It should be noted that the conveying roller assembly 51 described in this embodiment is used to smoothly convey the pipe fittings. The third drive unit 52 is a device for controlling the height adjustment of the conveying roller assembly 51. The third drive unit 52 is synchronously controlled with the front and rear lifting devices 42 to ensure stable conveying of the pipe fittings in an inclined posture, and to adjust them to a horizontal state after the pellets are discharged. The third drive unit 52 consists of an electric telescopic rod and a motor. While the electric telescopic rod controls the height adjustment of the rollers inside the conveying roller assembly 51, the motor synchronously drives the rotation of the rollers through the sprocket.

[0041] In summary, the round tube shot blasting machine of this utility model embodiment uses a lifting device to control two positioning rollers to move downwards. With the cooperation of the conveying component, the rear end of the tube is offset downwards. The shot particles entering the rear end of the tube fall out of the tube due to their own gravity, preventing the shot particles from accumulating at the rear end of the tube. After the front end of the tube is separated from the front conveying component, the lifting device controls the two positioning rollers to move downwards. With the cooperation of the conveying component, the front end of the tube is kept conveyed downwards. The shot particles entering the front end of the tube fall out of the tube due to their own gravity, preventing the shot particles from being placed outside the device and reducing the need for additional shot cleaning steps.
