DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1-Figure 3As shown, a spinning workpiece blasting test furnace with an auxiliary entry and exit mechanism comprises a furnace body 1 and a bottom frame 2 for supporting the furnace body 1, wherein the furnace body 1 is cylindrical and is laterally fixed to the upper end of the bottom frame 2, and the outer wall of the furnace body 1 is provided with a plurality of water inlets 11 communicating with the interior thereof and connected to a pressurizing device, and the lowest part of the outer wall of the furnace body 1 is connected with a plurality of drain ports 12, and further comprises an auxiliary entry and exit mechanism 3, the furnace body 1 has openings on both sides and a flip cover 13 is hinged on the opening, and the auxiliary entry and exit mechanism 3 is arranged on one side of the furnace body 1 and is hinged with the opening on the side The auxiliary in-and-out mechanism 3 includes a frame 31, a receiving groove 33, a rotating wheel 37 and a connecting rod 39. A baffle plate 32 is provided on the upper end surface of the frame 31 near the opening of the furnace body 1. A through hole 321 is provided on the baffle plate 32 for the spinning workpiece to pass through. A clearance space 4 for the flip cover 13 to flip is provided between the baffle plate 32 and the opening of the furnace body 1. First slide rails 311 are provided on both sides of the upper end surface of the frame 31 along its length direction. Second slide rails 312 parallel to the first slide rails 311 are provided on both sides of the frame 31. A shaft seat 34 is symmetrically provided to be slidably matched therewith, a linkage plate 38 is fixedly connected to the side of the shaft seat 34, a roller 381 is rotatably provided at the lower end of the linkage plate 38, a first motor 382 that can drive the roller 381 to rotate is fixed on the linkage plate 38, a door frame 35 is fixedly connected to one side of the shaft seat 34, a slide cylinder 36 is fixed on the door frame 35, a slide column 361 is slidably provided in the slide cylinder 36, the rotating wheel 37 is rotatably provided between the shaft seats 34, a second motor 371 that can drive the rotating wheel 37 to rotate is fixed on one side of the shaft seat 34, One end of the rod 39 is eccentrically hinged on the rotating wheel 37, and the other end is hinged to the sliding column 361. The receiving groove 33 is fixedly connected to the upper end surface of the frame 31, one side of which is connected to the through hole 321, and the other side is connected to the slide cylinder 36 and can allow the slide cylinder 36 to pass through. The upper end surface of the frame 31 is provided with a first sliding hole 313 for the rotating wheel 37 to pass through along its length direction, and a second sliding hole 331 for the rotating wheel 37 to pass through is provided at the bottom of the receiving groove 33. The bottom of the furnace body 1 and the bottom surface of the receiving groove 33 are both provided with a conveying component 5 for rolling and conveying the spun workpiece.

[0023] The first motor 382 is started to start the first motor 381, and the roller 381 rolls along the second slide rail 312, and the shaft seat 34 is driven to slide along the first slide rail 311 through the linkage plate 38, and the door frame 37 drives the slide cylinder 36 to push the workpiece, and gradually sends it into the furnace body 1 through the transmission component 5, and the clearance space 4 is mainly used to make room for the flip cover 13 to turn over. When the slide cylinder 36 abuts against the baffle plate 32, part of the workpiece is left in the clearance space 4. At this time, the second motor 371 is started to drive the rotating wheel 37 to rotate one circle, and the slide column 361 slides along the slide cylinder 36 to send the whole workpiece into the furnace body 1, and the flap 13 is closed to slowly increase the water pressure to the water inlet 11 with a certain pressure increment before the blasting test can be carried out. Since the diameter of the rotating wheel 37 is relatively large, the first slide hole 313 and the second slide hole 331 are used to allow the rotating wheel 37 to penetrate and make way during the transmission of the spinning workpiece.

[0024] Furthermore, if Figure 4-Figure 6 As shown, the conveying component 5 includes two conveying tracks 51 arranged in mirror image, a plurality of conveying shafts 52 are fixed between the conveying tracks 51, two conveying wheels 53 arranged in mirror image are rotatably provided on the conveying shafts 52, and the conveying shafts 52 on the conveying component 5 located on the bottom surface of the receiving groove 33 are all disconnected in the middle to allow the rotating wheel 37 to pass through and make way.

[0025] The transmission track 51 , the transmission shaft 52 and the transmission wheel 53 are all made of alloy steel with a yield strength greater than or equal to 500 MPa.

[0026] The transmission assembly 5 is arranged in the furnace body 1 and needs to withstand a relatively high water pressure. Although the cost of using alloy steel materials increases, it can reduce maintenance costs and increase service life.

[0027] The outer end of the sliding column 361 is concave to form a traction groove 362 , and a hook 6 is fixed in the traction groove 362 .

[0028] After the test is completed, one end of the damaged spun workpiece is wrapped around its end by a wrapping belt with high friction and fixed to the hook 6. By rotating the wheel 37 for one circle, one end of the spun workpiece is first pulled out of the furnace body 1 to the clearance space 4, and then the slide cylinder 36 and the slide column 361 are driven to move as a whole through the shaft seat 34, so that the tested spun workpiece is pulled to the receiving groove 33, and finally hoisted as a whole by the hoisting equipment. Since the traction groove 362 is concavely arranged on the outer end surface of the slide column 361, it will not affect the process of pushing the spun workpiece.

[0029] The height of the frame 31 is 60-80 cm, which is convenient for operators to observe the process of hoisting and conveying the spinning workpiece into the furnace body 1, and to make timely feedback to ensure that the spinning workpiece enters and exits the furnace body 1 smoothly.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
