Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a closing device. Background Technology

[0002] In the wheel manufacturing process, wheel components such as seat rings, rims, engineering retaining rings, cylinder bodies, and grooved rings require tack welding on their annular blanks before welding. The main purpose is to ensure the stability and reliability of the wheel components during subsequent processing and use. Tack welding firmly connects the wheel components together, preventing loosening or separation during distribution. Tack-welded wheel components are also easier to weld later. Traditionally, the tack welding process involves placing the wheel component blank directly on a hydraulic press, applying pressure to align the blanks, and then tack welding. However, once the blanks are placed on the press, it's difficult to ensure that both ends are aligned at the joint, affecting the welding effect. Manual adjustment is often required, resulting in inconvenience in the wheel component welding process. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fitting device to solve the problem of inconvenient fitting of existing wheel accessory blanks.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] Optionally, the clamping member includes two clamping blocks respectively fixed to the top ends of a pair of guide blocks, and the top ends of the clamping blocks are provided with protrusions.

[0010] Optionally, two clamping rollers are arranged side by side between the two clamping blocks. The clamping rollers are distributed perpendicular to the clamping blocks.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above scheme, the annular blank to be joined is placed on the base by setting up clamping parts and a joining mold. The annular blank to be joined is placed between a pair of clamping blocks. The joining mold is pressed down by a hydraulic cylinder to join the blank. The pair of clamping blocks in the clamping parts are driven by a drive mechanism to move closer together to perform a clamping action, clamping and fixing the joined blank. With the pressing down of the joining mold, the blank is kept in a joined and aligned state. A welding machine is used to spot weld the joined part of the blank, connecting the two ends of the blank together to form an integral structure. This makes it easier for the wheel blank to undergo subsequent butt welding processing.

[0034] like Figures 1 to 7As shown, an embodiment of this utility model provides a closing device, including a hydraulic body 1. A hydraulic cylinder 2 is mounted on the top of the hydraulic body 1, and a connector 3 is mounted on the telescopic end of the hydraulic cylinder 2. A closing mold 4 is provided on the connector 3. A base 6 is provided on the hydraulic body 1, and a clamping member 7 is provided on the upper surface of the base 6. A driving mechanism capable of driving the clamping member 7 to perform clamping actions is also provided on the base 6. The clamping member 7 includes two clamping blocks 16, and a protrusion 18 is provided at the top of each clamping block 16. Through this structural design, the hydraulic cylinder 2 is lifted to drive the closing mold 4 to rise, placing the annular blank to be closed on the base 6. Between the clamping blocks 16, the hydraulic cylinder 2 is activated to press down the closing mold 4. The closing mold 4 contacts the blank to be closed and continues to press down to close the blank. Then, the drive mechanism drives a pair of clamping blocks 16 in the clamping member 7 to move closer together to perform a clamping action, clamping and fixing the closed blank. With the pressing down of the closing mold 4, the blank is kept in a closed and aligned state. A welding machine is used to perform spot welding on the closed part of the blank, so that the two ends of the blank are connected together to form an integral structure. This makes it easier for the wheel accessory blank to be welded later. The whole blank is closed by pressing down the closing mold 4 and clamping the clamping member 7, which reduces manual intervention and improves the closing efficiency.

[0035] like Figure 1 and Figure 5 As shown, the closing mold 4 includes a connecting plate 19 connected to the bottom of the connecting head 3 and a closing pressure plate 20 disposed below the connecting plate 19. The closing pressure plate 20 is bent downward in an arc shape to adapt to the arc structure of the blank. Multiple connecting columns 21 are vertically connected between the closing pressure plate 20 and the connecting plate 19. Vertical rods 5 are vertically fixed at the four corners of the upper surface of the connecting head 3. The top of the vertical rods 5 is movably inserted into the hydraulic press body 1 to guide the lifting and lowering of the closing mold 4.

[0036] like Figures 1 to 4As shown, the base 6 has a guide groove 10, and a pair of guide blocks 15 are slidably embedded in the guide groove 10. Two clamping blocks 16 in the clamping member 7 are respectively assembled on the pair of guide blocks 15. The guide groove 10 is distributed along the axial direction of the closing pressure plate 20, and the clamping blocks 16 are distributed perpendicular to the guide groove 10. The driving mechanism includes a shell arm 11 set on the lower surface of the base 6. The shell arm 11 is embedded in the hydraulic press body 1 and distributed along the length direction of the guide groove 10. A bidirectional lead screw 13 is rotatably assembled in the shell arm 11. A pair of sliders 14 are slidably embedded in the shell arm 11. The pair of sliders 14 are symmetrically threaded with the bidirectional lead screw 13. A pair of guide blocks 15 are respectively fixedly connected to a pair of sliders 14. A motor 12 for driving the bidirectional lead screw 13 to rotate is installed at the end of the shell arm 11. When the motor 12 is started, the bidirectional lead screw 13 is rotated, which drives the pair of sliders 14 to bring the guide blocks 15 and the pair of clamping blocks 16 closer together, so as to clamp and position the closing blank. Two closing rollers 17 are arranged side by side between the two clamping blocks 16. The closing rollers 17 are distributed perpendicular to the clamping blocks 16. One end of the closing roller 17 is rotatably connected to one of the clamping blocks 16, and the other end of the closing roller 17 passes through the other clamping block 16. During the closing process of the closing mold 4 pressing down on the blank, the pair of closing rollers 17 can provide rolling support to the bottom of the blank, promoting the closing of the blank.

[0037] like Figure 1 and Figure 6 As shown, support feet 8 are provided at the four corners of the side wall of the hydraulic press body 1, and foot posts 23 are provided on the lower surface of the support feet 8. A reinforcing plate 22 is connected between the upper surface of the support feet 8 and the side wall of the hydraulic press body 1 for stable support of the hydraulic press body 1.

[0038] like Figure 1 and Figure 7 As shown, dust collection covers 9 are installed on both sides of the top of the hydraulic press body 1. The top of the dust collection cover 9 is connected to a secondary air duct 24. The tops of the pair of secondary air ducts 24 are interconnected and connected to a main air duct 25. The main air duct 25 is connected to an exhaust fan. During the welding process, the exhaust fan, together with the main air duct 25, the secondary air duct 24 and the dust collection cover 9, can remove the dust and exhaust gas generated during the welding process, reducing the harm of exhaust gas and dust to the environment and workers. A baffle 26 is provided on the bottom side of the dust collection cover 9 away from the hydraulic press body 1, which is conducive to removing exhaust gas and dust generated by welding on the base 6.

[0039] The workflow of the technical solution provided by this utility model is as follows:

[0040] In use, the lifting hydraulic cylinder 2 drives the closing mold 4 to rise, placing the annular blank to be closed on the base 6. The annular blank to be closed is placed between a pair of clamping blocks 16. The hydraulic cylinder 2 is activated to press down the closing mold 4, and the closing mold 4 contacts the blank to be closed. The curved closing pressure plate 20 is used to press down to close the blank. Then, the motor 12 is activated to drive the bidirectional lead screw 13 to rotate, driving a pair of sliders 14 to move the guide block 15 and a pair of clamping blocks 16 to move closer together to perform a clamping action, clamping and fixing the closed blank. With the pressing down of the closing mold 4, the blank is kept in a closed and aligned state. A welding machine is used to perform spot welding on the closed part of the blank, connecting the two ends of the blank together to form an integral structure. This makes it easier for the wheel accessory blank to be welded later. The entire blank is closed by pressing down the closing mold 4 and clamping the clamping parts 7, which reduces manual intervention and improves the closing efficiency. During the welding process, the main air duct 25 is connected to the exhaust fan, which, together with the auxiliary air duct 24 and the dust collection hood 9, can remove the dust and exhaust gas generated during the welding process.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
