Description

Technical Field

[0001] This utility model relates to the field of cold drawing machine technology, and more specifically to a cold drawing machine for cold drawing wire processing. Background Technology

[0002] Cold-drawn wire is a low-carbon steel wire produced by cold drawing and is a common product in the field of metal pressure processing. The production process involves drawing raw materials (such as hot-rolled round bars) through drawing dies with progressively smaller diameters at room temperature, causing the steel wire to undergo plastic deformation, thereby reducing its diameter, increasing its strength, and improving its performance.

[0003] For example, the prior art disclosure number CN221018034U describes a wire drawing machine for cold drawing. This utility model uses an electromagnetic coil to energize the permanent magnet block, thereby pushing the sliding cavity inside the limiting block to move outward, which in turn pushes the slide rod to move outward, causing the straightening wheel to contact the steel wire material, thereby straightening the steel wire material. It can straighten steel wire materials of different diameters, thus improving the applicability of the device.

[0004] However, the existing technology described above still has the following problems in use: the multiple drums on a traditional cold drawing machine are in fixed positions, and the deformation of the wire cannot be adjusted during the cold drawing process, resulting in low cold drawing efficiency. Based on this, this utility model provides a cold drawing machine for cold drawing wire processing, which can adjust the deformation by adjusting the drum spacing, thereby improving cold drawing efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a cold drawing machine for cold drawing wire processing. It comprises a multi-stage wire drawing structure consisting of multiple rollers and wire-reaming rollers on multiple slide blocks, thereby enabling continuous reduction and shaping of the wire material. Furthermore, the operator can push the slide blocks to move within the groove, and by adjusting the distance between adjacent rollers, deformation can be reduced, preventing the wire material from breaking due to excessive stress, and the single-drawing efficiency can be improved, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cold drawing machine for cold drawing wire processing, comprising a processing table, a table surface fixedly provided on the top of the processing table, a sliding groove provided on the top of the table surface, a plurality of evenly distributed cold drawing components provided inside the sliding groove, each cold drawing component including a slide seat provided in the sliding groove, a drum, a wire guiding roller and a wire drawing die provided on the top of the slide seat, the wire guiding roller and the wire drawing die being provided in front of the drum, a protective mechanism provided at the front end of the table, the protective mechanism including a protective mesh plate, a connecting block connected to the bottom end of the protective mesh plate, a linear module connected to each of the two connecting blocks, and mounting grooves provided on both sides of the front end of the processing table, the linear module being fixed in the mounting groove.

[0007] In a preferred embodiment, a geared motor is fixedly installed at the bottom of each slide, and a rotating rod is fixedly installed at the top of the output shaft of the geared motor. A through hole is opened at the top of each drum, and the top of the rotating rod passes through the through hole and is detachably connected to the drum. The drum is driven to rotate by the geared motor and the rotating rod to improve the wire drawing effect.

[0008] In a preferred embodiment, each slide block is threaded with a plurality of equally spaced fastening bolts at its top, and the bottom wall of the slide groove is provided with a plurality of equally spaced threaded holes. The slide block is threadedly connected to the threaded holes by the fastening bolts and fixed by the fastening bolts, which facilitates the operator to quickly adjust the position of the slide block.

[0009] In a preferred embodiment, a grating transmitter and a grating receiver are fixedly provided on both sides of the top of the table. The grating transmitter and the grating receiver are located behind the protective mesh plate. By using the grating transmitter and the grating receiver in combination, a protective function can be provided in front of the drum, thereby improving the safety of the workers.

[0010] In a preferred embodiment, door panels are hinged to both sides and the front end of the processing table, and the number of door panels at the front end of the processing table is set to multiple. The multiple door panels at the front end of the processing table are all located behind the protective mesh panel. The door panels facilitate the storage of items inside the processing table by the staff.

[0011] In a preferred embodiment, baffles are fixedly provided on both sides of the top of the processing table. Both baffles abut against the side wall of the table surface. The two baffles are respectively located on both sides of the grating transmitter and the grating receiver. The two baffles are used to block the slide from falling out of the slide groove on both sides of the table surface. At the same time, by removing the baffles, the operator can push the slide out of the slide groove for inspection and replacement.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses multiple rollers and wire-reaming rollers on multiple slides to form a multi-stage wire drawing structure, which can achieve continuous weight reduction and shaping of the wire. In addition, the operator can push the slide to move in the groove. By adjusting the distance between two adjacent rollers, the amount of deformation can be reduced, the wire can be prevented from breaking due to excessive stress, and the single drawing efficiency can be improved.

[0014] 2. The height of the protective mesh plate is automatically adjusted by the linear module. The protective mesh plate stops in front of multiple rolls, which can play a protective role and prevent accidental wire breakage that could cause injury to workers. This can effectively improve the safety of the cold drawing machine. When the workers need to adjust the position of the rolls, the protective mesh plate can automatically descend below the table to avoid obstruction. Attached Figure Description

[0023] 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.

[0024] Refer to the instruction manual appendix Figures 1-5 This utility model provides a cold drawing machine for cold drawing wire processing, including a processing table 1. The top of the processing table 1 is fixedly provided with a table surface 2. The top of the table surface 2 is provided with a sliding groove 3. The sliding groove 3 is provided with a plurality of evenly distributed cold drawing components 4. The cold drawing components 4 include a slide seat 41 provided in the sliding groove 3. The top of the slide seat 41 is provided with a drum 42, a wire guiding roller 43 and a wire drawing die 44. The wire guiding roller 43 and the wire drawing die 44 are located in front of the drum 42. A handle can also be provided on the top of each slide seat 41 to facilitate the operator to quickly adjust the position of the slide seat 41.

[0025] Each slide block 41 is fixedly equipped with a reduction motor 6 at its bottom. The top of the output shaft of the reduction motor 6 is fixedly equipped with a rotating rod 7. Each drum 42 has a through hole 8 at its top. The top of the rotating rod 7 passes through the through hole 8 and is detachably connected to the drum 42. The reduction motor 6 drives the drum 42 to rotate stably, thereby improving the safety of the cold drawing process. Each slide block 41 is threaded with multiple equally spaced fastening bolts 9 at its top. The bottom wall of the slide groove 3 has multiple equally spaced threaded holes 10. The slide block 41 is threadedly connected to the threaded holes 10 by the fastening bolts 9.

[0026] In practical use, the wire guide roller 43 winds around the outer wall of the drum 42, then passes through the drawing die 44 and the guide roller 43 from the drum 42 and winds onto the next drum 42. Finally, it flows out from the drum 42 and the drawing die 44 of the last slide 41. The drums 42 and guide rollers 43 on multiple slides 41 form a multi-stage wire drawing structure, which can achieve continuous weight reduction and shaping of the wire. In addition, during the drawing process, the operator can loosen the fastening bolts 9 on the slide 41 and push the slide 41 to move in the groove 3. By reducing the distance between two adjacent drums 42, the amount of deformation can be reduced, and the wire can be prevented from breaking due to excessive stress. Increasing the distance can improve the single drawing efficiency while ensuring the bearing capacity of the wire and the die.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, door panels 13 are hinged to both sides and the front end of the processing table 1, and the number of door panels 13 at the front end of the processing table 1 is set to multiple. The multiple door panels 13 at the front end of the processing table 1 are all located behind the protective mesh plate 51. The door panels 13 are set to facilitate the storage of items inside the processing table 1 by the staff.

[0028] Furthermore, baffles 14 are fixedly installed on both sides of the top of the processing table 1. Both baffles 14 abut against the side wall of the table surface 2. The two baffles 14 block the slide 41 from the slide groove 3 on both sides of the table surface 2. At the same time, by removing the baffles 14, the staff can push the slide 41 out of the slide groove 3 for inspection and replacement.

[0029] When the wire moves at high speed, there is no protection set in front of the cold drawing machine. If the staff accidentally collide with the cold drawing machine and the wire during the inspection process, they will be injured. At the same time, the wire may break or other unexpected situations may occur during the cold drawing process. Therefore, a protective mechanism 5 is set at the front end of the table 2. The protective mechanism 5 includes a protective mesh plate 51. The bottom end of the protective mesh plate 51 is connected to a connecting block 52. A linear module 53 is connected to both connecting blocks 52. The front sides of the processing table 1 are provided with mounting grooves 54, and the linear module 53 is fixed in the mounting groove 54.

[0030] During the cold drawing process, the two linear modules 53 drive the protective mesh plate 51 to slide vertically through the screw nut mechanism, causing the protective mesh plate 51 to move upward. The protective mesh plate 51 stops in front of multiple drums 42. When the wire breaks accidentally, the protective mesh plate 51 can play a protective role, avoiding accidental injury to the workers, thereby effectively improving the safety of the cold drawing machine. When the workers need to adjust the position of the drums 42, the protective mesh plate 51 can automatically descend below the table 2 to avoid obstruction.

[0031] And, as Figure 1 As shown, a grating transmitter 11 and a grating receiver 12 are fixedly installed on both sides of the top of the table 2. The grating transmitter 11 and the grating receiver 12 are located behind the protective mesh plate 51, and two baffles 14 are respectively installed on both sides of the grating transmitter 11 and the grating receiver 12.

[0032] Multiple infrared LEDs in the grating transmitter 11 emit infrared beams to form a dense infrared light curtain. The infrared receiver array in the grating receiver 12 corresponds one-to-one with the infrared LEDs in the grating transmitter 11. Each infrared receiver receives one beam of infrared light. If an infrared receiver does not receive light (the beam is blocked), the channel is determined to be "blocked" and a signal is sent to the controller of the cold drawing machine to stop it, thereby improving the safety of the staff.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
