Description

Technical Field

[0001] The invention relates to the field of wheel brush production equipment, in particular to a device for processing curved wire wheel brush filaments. Background Art

[0002] The wire sheet is a key functional component of the wheel brush series, achieving effects such as polishing and grinding. Its structure mainly includes a large number of steel wires, inner rivets, and inner rings. The steel wires need to be fixed between the inner rivets and the inner ring. Therefore, the wire sheet manufacturing process includes four steps: wire cutting, wire threading, pre-pressing, and forming. The current wire cutting equipment is a common cutting device with a relatively simple structure. It cannot collect the cut steel wire, resulting in relatively low production efficiency. In addition, the wire threading process currently uses a guide structure to pass the steel wire between the inner rivet and the inner ring. However, this will result in uneven distribution of the steel wire between the inner rivet and the inner ring, affecting the quality of the wire sheet. Therefore, a new processing device is needed to meet the needs of fast and high-quality wire sheet production. Summary of the Invention

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] The wire sheet is a key functional component of the wheel brush series, achieving effects such as polishing and grinding. Its structure mainly includes a large number of steel wires, internal rivets, and an inner ring. The steel wire needs to be fixed between the inner rivet and the inner ring. Therefore, the wire sheet manufacturing process includes four steps: wire cutting, wire threading, pre-pressing, and forming. Currently, the equipment for these four steps is placed in different areas. If the same equipment is set up side by side in one area, it requires turnover between different steps, which limits production efficiency. Among them, the existing wire cutting equipment is a simple cutting device with an ordinary structure. It cannot automatically collect the cut wire and requires manual operation. This has low production efficiency and poses safety risks. In addition, the wire threading process currently uses a guide structure to pass the steel wire between the inner rivet and the inner ring. However, this results in uneven distribution of the steel wire between the inner rivet and the inner ring, affecting the quality of the wire sheet and reducing efficiency. Therefore, a new processing device is needed to meet the needs of fast and high-quality wire sheet production.

[0029] like Figure 1-10As shown, specifically, the present invention provides a curved wire wheel brush sheet processing device, including a wire cutting device 1, a wire threading device 2, a pre-pressing device 3 and a forming device 4 arranged in sequence; the wire cutting device 1 includes a wire pushing assembly 11, a wire cutting assembly and a wire drum support assembly arranged between the wire pushing assembly 11 and the wire cutting assembly, the wire drum support assembly includes a wire drum 5 and a first driving motor 19 that drives the wire drum 5 to rotate, the wire drum 5 includes an annular seat 58 and a plurality of wire threading drums 56 arranged along the circumference of the annular seat 58, the wire pushing assembly 11 includes a wire pressing roller 12 arranged in an upper and lower relative manner and a wire guide tube 17 arranged on the front and rear sides of the wire pressing roller 12, the rear side of the wire pressing roller 12 is provided with a wire feeding guide seat 16 driven by a first cylinder 35 to move horizontally, one end of the wire feeding guide seat 16 corresponds to the wire threading drum 56, the wire passes through between the wire pressing roller 12, the wire guide tube 17 and the wire feeding guide seat 16 into the wire threading drum 56, the wire The wire cutting assembly includes a first drive motor 14 and a blade 15 driven by the second drive motor 14 on one side of the wire cutting assembly, which is used to cut the wire between the wire threading cylinder 56 and the wire feeding guide 16. Specifically, the wire guide tube 17 at the front end of the wire cutting device 1 is connected to the wire conveyor, and the bundled wire passes through the wire guide tube 17 and enters between the two wire pressing rollers 12. The outer surface of the wire pressing roller 12 is evenly arranged. There are several convex teeth, and the convex teeth of the two wire pressing rollers 12 are staggered and meshed. The tops of the convex teeth are provided with arc-shaped grooves. The mutual meshing of the convex teeth can effectively pull the bundled steel wires, so that the bundled steel wires can be transported forward. The steel wires coming out of the two wire pressing rollers 12 pass through the wire guide tube 17 on the rear side of the wire pressing roller 12, and then pass through the wire feeding guide seat 16. The blades 15 can be arranged in a pair, and the steel wire is located between the blades 15 to ensure that the bundled steel wires can be quickly cut.

[0030] When the wire feeding guide 16 is inserted into one end of the wire threading tube 56, the two wire pressing rollers 12 can feed the wire forward and into the wire threading tube 56, and then the wire feeding guide 16 retreats, and the blade 15 cuts it at a position close to the wire threading tube 56. The wire tube 5 rotates an angle, and the wire feeding guide 16 is aligned with the next wire threading tube 56, and the cycle continues.

[0031] A quick-release structure for supporting the wire reel 5 is provided in the wire reel support assembly. The quick-release structure is connected to the first drive motor 19 through a transmission belt to drive the wire reel 5 to rotate in an indexed manner. After all the wire threading reels 56 of the wire reel 5 are inserted with steel wires, the wire reel 5 can be quickly removed as a whole and placed in the wire threading device 2.

[0032] The steel wire advancing assembly 11 includes a bracket and a lifting block located on the bracket for lifting. A pair of wire pressing rollers 12 are respectively installed on the bracket and the lifting block. The lifting block is driven by the eighth cylinder 13 at the upper end of the bracket to lift and lower. Any wire pressing roller 12 is driven to rotate by the third drive motor 20. By driving a wire pressing roller 12 to lift and lower by the eighth cylinder 13, it is convenient to place the bundled steel wire between the two wire pressing rollers 12. The wire drum support assembly is installed on a sliding plate. The sliding plate is connected to the ninth cylinder 18 on one side. The wire drum support assembly is moved out by the ninth cylinder 18 to facilitate the removal of the wire drum 5.

[0033] In this embodiment, if Figure 4-5 As shown, the wire threading device 2 includes a pair of wire tube clamping blocks 27 driven by a third cylinder 21, and an inner ring positioning groove 29 for placing the inner ring is formed at the lower part between the wire tube clamping blocks 27, and an inner rivet pillar 22 is vertically passed through the inner ring positioning groove 29. The inner rivet pillar 22 is driven to rise and fall by the fourth cylinder 23 at its lower end, and a guide column 25 driven to rise and fall by the fifth cylinder 26 is provided above the inner rivet pillar 22. The outer side of the guide column 25 is provided with a wire pressing column 24 corresponding to the wire threading tube 56 around the circumference, and the guide column 25 descends and extends into the middle of the wire tube 5, and the wire pressing column 24 presses the steel wire in the wire threading tube 56 into between the inner ring and the inner rivet. Specifically, a plurality of limiting holes 57 are provided around the circumference on the outer side wall of the annular seat 58, and a wire tube clamping assembly corresponding to the limiting holes 57 is horizontally provided on the side wall of the wire tube clamping block 27. The wire tube clamping assembly includes a guide tube 52 installed, and a limiting rod 53 extending toward the inner side of the wire tube clamping block 27 is installed inside the guide tube 52. A rear cover 54 is provided at the tail of the guide tube 52, and a spring 55 is provided inside the guide tube 52 which is sleeved on the limiting rod 53. One end of the spring 55 is against the rear cover 54, and the other end is against the limiting rod 53. By setting the limiting rod 53, the wire tube 5 can be inserted into the limiting hole 57 when it is placed between the wire tube clamping blocks 27 to position the wire tube 5, so as to prevent the wire pressing column 24 from being unable to align with the corresponding wire threading tube 56.

[0034] Specifically, during operation: the third cylinder 21 closes the wire drum clamping block 27 and pushes the inner ring into the inner ring positioning groove 29; the fourth cylinder 23 pushes the inner rivet pillar 22 between the wire drum clamping blocks 27, so that the end of the inner rivet pillar 22 is higher than the wire drum clamping block 27, and the inner rivet is placed on the inner rivet pillar 22; the wire drum 5 filled with steel wire bundle is placed into the wire drum clamping block 27, and the limit rods 53 at the left and right ends guide the wire drum 5 to enter at the required angle, and after the wire drum 5 enters, it is inserted into the limit hole 57 on the wire drum 5 to ensure that the wire drum 5 does not shift during operation. A limit switch can be installed on the rear side of the limit rod 53. The limit switch can ensure that the machine cannot continue to operate if the limit rod 53 is not in place; the fifth cylinder 26 drives the guide column 25 and the wire pressing column 24 downward, the guide column 25 is inserted into the middle of the wire drum 5, and the wire pressing column 24 enters the wire threading drum 56 to push the steel wire bundle out of the wire drum 5 to complete the threading. The fifth cylinder 26 drives the guide post 25 and the wire pressing post 24 back to their original positions, while the fourth cylinder 23 retracts the inner rivet support 22. The inner rivet is then clamped in the middle of the inner ring by the expansion of the wire bundle. The third cylinder 21 retreats, causing the wire drum clamping block 27 to separate, the limiting rod 53 to leave the limiting hole 57, and the wire drum 5 to fall off.

[0035] The inner sidewall of the spool clamping block 27 is provided with a tapered guide surface 51 that extends toward the inner ring positioning groove 29. This guide surface 51 guides the steel wire extruded from the wire threading barrel 56, directing it between the inner ring and the inner rivet. The lower side of the spool clamping block 27 is connected to the extended rod of the third cylinder 21 via a connecting block 28. The spool clamping block 27 is semicircular in shape, allowing the third cylinder 21 to be symmetrically positioned on either side of the spool clamping block 27.

[0036] In this embodiment, if Figure 6 As shown, the pre-pressing device 3 includes a vertically arranged lower mold 32 and an upper mold 33 located above the lower mold 32 and driven by the seventh cylinder 36 to rise and fall. A guide rod 37 is vertically passed through the middle of the lower mold 32. The guide rod 37 is driven to rise and fall by the sixth cylinder 31 at its lower end. A guide hole for inserting the guide rod 37 is provided in the center of the upper mold 33. When in use, 1. The semi-finished product that has completed threading is passed through the semi-finished product guide rod 37, and the sixth cylinder 31 pushes the guide rod 37 toward the upper mold 33 and into the guide hole of the upper mold 33; 2. The seventh cylinder 36 pushes the upper mold 33 to move downward and compresses the sixth cylinder 31 to retract. After reaching the predetermined position, the sixth cylinder 31 actively retracts the semi-finished product guide rod.

[0037] In this embodiment, if Figure 7As shown, the forming device 4 includes a forming lower mold 41 and a forming upper mold 42 which can be raised and lowered above the forming lower mold 41. A positioning column is provided on the upper side of the forming lower mold 41, and a positioning hole which cooperates with the positioning column is provided in the center of the lower end face of the forming upper mold 42. The wire cutting device 1, the wire threading device 2, the pre-pressing device 3 and the forming device 4 are arranged together, and can be operated by one person, so that the processing efficiency is high.

[0038] The slitting device 1, threading device 2, pre-pressing device 3, and forming device 4 are arranged in a semicircle, allowing workers to stand within this semicircle, reducing the distance they move. All four processes are set to start with one button, requiring no human intervention. After processing, the product remains on the machine, eliminating the need to pick up dropped items.

[0039] In actual production, there are two wire reels 5 in the wire cutting process. After one of the wire reels completes the wire cutting process, it is replaced by another wire reel, and the wire reel that has completed the wire cutting process is moved to the wire threading process; after the wire threading process is started, the semi-finished product is sent to the pre-pressing process; after the pre-pressing process is started, the pre-pressed product is sent to the pressing process; when it comes back, the wire threading process has been completed, and the empty wire reel is taken back to the wire cutting process, and the wire cutting process should have been completed. After the wire reel is replaced, the wire reel that has completed the wire cutting process is moved to the wire threading process... and the cycle repeats.
