Description

Technical Field

[0001] This utility model relates to the field of metal wire drawing machine technology, and in particular to a safe metal wire drawing machine. Background Technology

[0002] A metal wire drawing machine, also known as a wire drawing machine or wire drawing machine, is a pre-processing equipment used in the production of standard parts and other metal products. Its main function is to draw wires or bars (usually made of steel) to ensure that their diameter, roundness, internal metallographic structure, surface finish, and straightness meet the specifications required for the production of standard parts and other metal products.

[0003] A search revealed a utility model patent in China with patent publication number CN220635839U, which discloses a metal wire drawing machine. The machine includes a housing and a drawing wheel disposed within the housing. A spray nozzle is installed inside the housing to spray coolant onto the drawing wheel. A liquid storage tank is located at the bottom of the housing. Exhaust channels are spaced apart at the top of the housing, and a fan is installed on the exhaust channels. A feed inlet is located at one end of the housing, and an outlet is located at the other end opposite the feed inlet. A cleaning mechanism is installed on the outlet to clean coolant residue from the surface of the metal wire. This utility model addresses the problem that existing wire drawing machines often fail to achieve effective cooling because the coolant does not come into contact with the drawing mechanism during cooling.

[0004] The aforementioned patent addresses the cooling of the wire drawing mechanism, but the device fails to handle wires of different diameters. Because the device cannot adapt to wires of different diameters, when different specifications of wire need to be processed, it may be necessary to replace the entire wire drawing mechanism or adjust the equipment parameters, which will consume a lot of time and manpower, resulting in poor wire drawing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a safe metal wire drawing machine. This device facilitates the metal wire drawing process for wires of various diameters, thereby solving the problem in the prior art that it is inconvenient to perform metal wire drawing on wires of various diameters.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safety-type metal wire drawing machine includes a base with a groove at its upper end, a movable rod slidably connected inside the groove, a support at the upper end of the base, and a winding reel between the inner walls of the two sides of the support; a housing located at the upper end of the base, with rollers one, two, and three rotatably connected inside the housing, each roller having multiple wire drawing holes arranged in a circular array on one side wall, the other two side walls, and the upper end of the housing having a top cover slidably connected to rollers one, two, and three, with a through groove inside the top cover; and a frame located at the upper end of the movable rod, with two movable frames slidably connected inside the frame, and rollers rotatably connected inside the movable frames, each roller having an annular groove on its side wall.

[0008] Preferably, a screw is rotatably connected inside the groove, a servo motor is fixedly connected inside the side wall of the base, the output end of the servo motor is fixedly connected to the end of the screw, and the screw is threadedly connected to the movable rod.

[0009] Preferably, both sides of the bracket are rotatably connected to protrusions, a drive motor is fixedly connected to the side wall of the bracket, the output end of the drive motor is fixedly connected to one of the protrusion side walls, and the inner wall of the protrusion is fixedly connected to the side wall of the winding reel.

[0010] Preferably, the roller disk has multiple toothed grooves arranged in a circular array on one side wall, two side walls and three side walls, and multiple gears are equidistantly rotatably connected inside the housing, with the gear sidewalls meshing with the toothed grooves.

[0011] Preferably, a crossbar is rotatably connected inside the housing, and the crossbar is fixedly connected to multiple gears through it. A motor is fixedly connected to the side wall of the housing, and the output end of the motor is fixedly connected to the end of the crossbar.

[0012] Preferably, two guide rods are fixedly connected to the side wall of the movable frame, and the guide rods are slidably connected through the side wall of the frame. Rotating rods are threadedly connected to both sides of the frame, and the ends of the rotating rods are rotatably connected to the side wall of the movable frame.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. When drawing wires of different diameters, the motor drives the crossbar to rotate, which in turn drives multiple gears to rotate synchronously. Through the engagement of the gear sidewalls and tooth grooves, rollers one, two, and three rotate synchronously, rotating the upper end of the corresponding drawing hole combination. The wire to be drawn passes through the corresponding drawing hole combination. After the wire passes through the combined drawing holes, the top cover is installed on the upper end of the housing. The wire is located inside the through groove, thus hiding the drawn wire inside the top cover, improving the safety of the device. The wire is drawn layer by layer into the required metal wire size through the drawing hole combination. The combination of multiple sets of drawing holes with different diameters facilitates the drawing of wires of various diameters. At the same time, the through groove inside the top cover provides a stable channel for the wire, preventing the wire from being affected by external interference or damage during the drawing process, maintaining the integrity and quality of the wire, and thus improving the reliability of the final product.

[0015] 2. After the wire is drawn, it passes through the frame. By manually rotating the rotating rod, the end of the rotating rod rotates on the side wall of the movable frame. At the same time, the rotating rod pushes the movable frame to slide laterally. The two movable frames drive the rollers inside to slide relative to each other, so that the two sides of the wire are in contact with the inner wall of the annular groove on the side wall of the two rollers, thereby clamping and limiting the wire, improving the safety of the device. When the wire breaks during the winding process, the clamping and limiting of the two rollers can quickly and firmly clamp the wire, preventing it from flying after breaking, thus protecting the safety of the operators and equipment.

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6A safety-type metal wire drawing machine includes a base 001, with a groove 101 on the upper end of the base 001. A movable rod 102 is slidably connected inside the groove 101. A support 105 is provided on the upper end of the base 001, and a winding reel 108 is provided between the inner walls of the two sides of the support 105. A housing 002 is located on the upper end of the base 001. Rollers 1 201, 202, and 3 203 are rotatably connected inside the housing 002. Multiple wire drawing holes 204 are arranged in a circular array through the side walls of rollers 1 201, 202, and 203. A top cover 209 is provided on the upper end of the housing 002, and the top cover 209 is connected to rollers 1 201 and 202 203 respectively. 2 and roller 3 203 are slidably connected. The upper cover 209 has a through groove 210 inside. Frame 003 is located at the upper end of movable rod 102. Two movable frames 301 are slidably connected inside frame 003. Rollers 304 are rotatably connected inside movable frames 301. The side wall of roller 304 is provided with annular grooves 305. The diameters of multiple wire-drawing holes 204 on the side wall of roller 1 201, roller 2 202, and roller 3 203 are different. The diameters of multiple wire-drawing holes 204 on the side wall of roller 1 201 are larger than those on the side wall of roller 2 202. The side wall of disc 203 has multiple wire-drawing holes 204 with the same diameter. The corresponding wire-drawing holes 204 on the side walls of disc 1, disc 201, disc 202, and disc 203 are kept at the same horizontal line, forming multiple sets of combined wire-drawing hole 204 combinations. When wires of different diameters need to be drawn, discs 1, 201, 202, and 3 rotate synchronously, rotating the upper end of the corresponding wire-drawing hole 204 combinations. The operator passes the wire to be drawn through the corresponding wire-drawing hole 204 combination. After the wire passes through the wire-drawing hole 204 combination, the top cover 209 is installed on the upper end of the housing 002, while the wire is located inside the through groove 210. The wire is hidden inside the top cover 209. The wire is drawn layer by layer into the required wire size through the drawing holes 204. The wire passes through the frame 003. The two movable frames 301 drive the rollers 304 inside to slide relative to each other, so that the two sides of the wire are in contact with the inner wall of the annular grooves 305 on the side wall of the two rollers 304, thereby clamping and limiting the wire. The rollers 304 rotate with the friction of the wire. Then the end of the wire is fixed to the side wall of the take-up reel 108. The wire is wound up by the rolling take-up reel 108. At the same time, the movable rod 102 drives the frame 003 to slide laterally, so that the rollers 304 move the wire and make the wire evenly wound onto the side wall of the take-up reel 108.

[0025] A screw 103 is rotatably connected inside the groove 101, and a servo motor 104 is fixedly connected inside the side wall of the base 001. The output end of the servo motor 104 is fixedly connected to the end of the screw 103. The screw 103 is threadedly connected to the movable rod 102. The servo motor 104 drives the screw 103 to rotate, so that the movable rod 102 slides laterally inside the groove 101.

[0026] Both sides of the bracket 105 are rotatably connected to protrusions 106. A drive motor 107 is fixedly connected to the side wall of the bracket 105. The output end of the drive motor 107 is fixedly connected to the side wall of one of the protrusions 106. The inner wall of the protrusion 106 is fixedly connected to the side wall of the take-up reel 108. The drive motor 107 drives one of the protrusions 106 to rotate. When one of the protrusions 106 rotates, it drives the take-up reel 108 to rotate, causing the other protrusion 106 to rotate accordingly.

[0027] The sidewalls of roller 1 201, roller 2 202, and roller 3 203 are all arranged in a circular array with multiple toothed grooves 205. Multiple gears 206 are equidistantly rotatably connected inside the housing 002. The sidewalls of the gears 206 mesh with the toothed grooves 205. Through the cooperation between the sidewalls of the gears 206 and the toothed grooves 205, when the multiple gears 206 rotate synchronously, roller 1 201, roller 2 202, and roller 3 203 rotate synchronously.

[0028] A crossbar 207 is rotatably connected inside the housing 002. The crossbar 207 is fixedly connected to multiple gears 206. A motor 208 is fixedly connected to the side wall of the housing 002. The output end of the motor 208 is fixedly connected to the end of the crossbar 207. The motor 208 drives the crossbar 207 to rotate, and at the same time, the crossbar 207 drives multiple gears 206 to rotate synchronously.

[0029] Two guide rods 302 are fixedly connected to the side wall of the movable frame 301. The guide rods 302 are slidably connected to the side wall of the frame 003. Both sides of the frame 003 are threadedly connected to rotating rods 303. The ends of the rotating rods 303 are rotatably connected to the side wall of the movable frame 301. Through the threaded connection between the rotating rods 303 and the side wall of the frame 003, when the rotating rods 303 are manually rotated, due to the transmission action of the threads, the rotating rods 303 will move along the side wall of the frame 003. At the same time, the ends of the rotating rods 303 are rotatably connected to the side wall of the movable frame 301. Therefore, the movement of the rotating rods 303 will push or pull the movable frame 301 to slide laterally along the guide rods 302.

[0030] In this invention, when wires of different diameters need to be drawn, the motor 208 drives the crossbar 207 to rotate. At the same time, the crossbar 207 drives multiple gears 206 to rotate synchronously. Through the cooperation between the sidewall of the gear 206 and the tooth groove 205, the roller 1 201, roller 202 and roller 3 203 rotate synchronously, rotating the upper end of the corresponding drawing hole 204 combination. The wire to be drawn passes through the corresponding drawing hole 204 combination. After the wire passes through the drawing hole 204 combination, the upper cover 209 is installed on the upper end of the housing 002. At the same time, the wire is located inside the through groove 210, thereby hiding the drawing wire inside the upper cover 209, improving the safety of the device. The wire is drawn layer by layer into the required metal wire size through the drawing hole 204 combination.

[0031] The drawn metal wire passes through the frame 003. By manually rotating the rotating rod 303, the end of the rotating rod 303 rotates on the side wall of the movable frame 301. At the same time, the rotating rod 303 pushes the movable frame 301 to slide laterally. The two movable frames 301 drive the rollers 304 inside them to slide relative to each other, so that the two sides of the metal wire are in contact with the inner wall of the annular groove 305 on the side wall of the two rollers 304, thereby clamping and limiting the metal wire and improving the safety of the device.

[0032] After the metal wire is clamped and positioned, the end of the metal wire is fixed to the side wall of the take-up reel 108. The drive motor 107 drives one of the protrusions 106 to rotate. When the protrusion 106 rotates, it drives the take-up reel 108 to rotate. The rolling take-up reel 108 winds up the metal wire. The servo motor 104 drives the screw 103 to rotate, so that the movable rod 102 slides laterally inside the groove 101. At the same time, the movable rod 102 drives the frame 003 to slide laterally, so that the roller 304 moves the metal wire, so that the metal wire is evenly wound onto the side wall of the take-up reel 108.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
