Description

TECHNICAL FIELD

[0001] The application relates to the field of molds, in particular to a cold-drawing steel fine-drawing mold. BACKGROUND

[0002] The cold-drawing steel fine-drawing is a metal processing process, which draws flat steel into more accurate, smoother size and surface quality through cold processing, and is usually used to improve the size accuracy, surface smoothness and mechanical properties of the flat steel.

[0003] When the cold-drawing steel fine-drawing is processed, the flat steel needs to be placed on the mold for processing, but after the use of some existing molds, there are processing debris on the mold, in order to prevent the influence of the debris on the processing, the debris on the mold needs to be cleaned, most of which is manually cleaned by using a cleaning brush, which is relatively troublesome and reduces the metal processing efficiency, and when the mold is used, the mold needs to be installed on the processing device, and some existing molds are installed through buckling, which is inconvenient to install. CONTENT OF THE UTILITY MODEL

[0004] The cold-drawing steel fine-drawing mold provided by the application does not need manual cleaning of the mold when the mold is used, improves the metal processing efficiency, and is simple and convenient in the installation and dismounting of the mold, and can fix different specifications of the mold.

[0005] In order to achieve the above purpose, the application adopts the following technical scheme: a cold-drawing steel fine-drawing mold, which comprises:

[0006] a shell;

[0007] a support plate fixedly arranged on one side of the shell, and a connecting frame arranged on one side of the support plate through a screw,

[0008] a lead screw arranged on both sides of the inner wall of the connecting frame through bearings, and a sleeve threadedly arranged on the outer surface of the lead screw, the sleeve moving to different positions on the outer surface of the lead screw when the lead screw rotates in different directions;

[0009] a support rod fixedly arranged on both sides of the inner wall of the connecting frame, and a sliding cylinder movably arranged on the outer surface of the support rod, the sliding cylinder being capable of sliding on the outer surface of the support rod;

[0010] a horizontal plate fixedly arranged on the outer surface of the sleeve, and a hollow cylinder fixedly arranged on one side of the horizontal plate, the horizontal plate driving the cleaning brush to move when the horizontal plate moves.

[0011] As a further improvement of this application: an elastic column is movably embedded on one side of the hollow cylinder, a cleaning brush is fixedly installed on one side of the elastic column, one side of the horizontal plate is connected to the outer surface of the slide cylinder, and the cleaning brush moves back and forth on the mold body to clean the debris on the mold body.

[0012] As a further improvement of this application: a limiting rod is movably embedded on the outer surface of the hollow cylinder, and multiple through holes are opened on the outer surface of the elastic column. The limiting rod is connected to any one of the through holes. By sliding the elastic column, the side of the cleaning brush with bristles is pressed tightly against the side of the mold body. At this time, the limiting rod is inserted into one of the through holes to fix the position of the elastic column.

[0013] As a further improvement of this application: a bidirectional motor is installed on one side of the connecting frame. The output shaft of the bidirectional motor is connected to the lead screw. When the external power switch of the bidirectional motor is turned on, the output shaft of the bidirectional motor can rotate in both directions, thereby driving the lead screw to rotate.

[0014] As a further improvement of this application: multiple first telescopic rods are fixedly provided on both sides of the inner wall of the connecting frame, and a second telescopic rod is movably embedded on one side of each of the multiple first telescopic rods, and the multiple second telescopic rods can slide on the inner wall of the multiple first telescopic rods respectively.

[0015] As a further improvement of this application: multiple second telescopic rods are grouped in pairs, and a fixing plate is fixedly installed on one side of each group of second telescopic rods. Springs are movably sleeved on the outer surface of multiple second telescopic rods. When the mold body is placed in the middle of the two fixing plates and the two fixing plates are released, the elastic force generated by the multiple springs squeezes the two fixing plates respectively, so that the two fixing plates clamp the two sides of the mold body.

[0016] As a further improvement of this application: a threaded cylinder is fixedly embedded on one side of one of the connecting frames, and a threaded rod is threadedly embedded in the inner wall of the threaded cylinder. Rotating the rotating ring clockwise drives the threaded rod to rotate, further causing one end of the threaded rod to move towards the side of the fixed plate. When the rotating ring cannot rotate, one side of the threaded rod is pressed against one side of one of the fixed plates, so that the two fixed plates fix the mold body and complete the installation of the mold.

[0017] As a further improvement of this application: a rotating ring is fixedly provided on one side of the threaded rod, and rotating the rotating ring drives the threaded rod to rotate, which facilitates the rotation of the threaded rod.

[0018] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0019] 1. In this application, after the flat steel is processed by the mold, the output shaft of the bidirectional motor can rotate in both directions by turning on the external power switch of the bidirectional motor. This drives the lead screw to rotate, and the slide cylinder can slide on the outer surface of the support rod. The slide cylinder is connected to the sleeve through the horizontal plate. Thus, when the lead screw rotates in different directions, the sleeve moves to different positions on the outer surface of the lead screw. At this time, the output shaft of the bidirectional motor is controlled to rotate clockwise, so that the sleeve moves towards the mold body. The elastic column can slide on the inner wall of the hollow cylinder and has elasticity. The limiting rod is removed from the hollow cylinder. By sliding the elastic column, the side of the cleaning brush with bristles is pressed against the mold body. At this time, the limiting rod is inserted into one of the through holes to fix the position of the elastic column. When the horizontal plate moves, it drives the cleaning brush to move. By controlling the output shaft of the bidirectional motor to rotate back and forth, the cleaning brush moves back and forth on the mold body to clean the debris on the mold body. Thus, when using the mold, manual cleaning of the mold is not required, improving the efficiency of metal processing.

[0020] 2. In this application, when using the mold, multiple second telescopic rods can slide on the inner walls of multiple first telescopic rods, pushing two fixed plates respectively. At this time, the mold body is placed in the middle of the two fixed plates. The two fixed plates are released, and the elastic force generated by multiple springs squeezes the two fixed plates respectively, so that the two fixed plates clamp the two sides of the mold body. Then, the rotating ring is rotated clockwise to drive the threaded rod to rotate, further moving one end of the threaded rod towards one side of the fixed plate. When the rotating ring can no longer rotate, one side of the threaded rod is pressed tightly against one side of one of the fixed plates, so that the two fixed plates fix the mold body, completing the installation of the mold. By rotating the rotating ring counterclockwise, one side of the threaded rod is released to press against one of the fixed plates. At this time, the two fixed plates are pulled to remove the mold body and disassemble the mold. Thus, when using the mold, the installation and disassembly method of the mold is simple and convenient, and different specifications of molds can be fixed at the same time.

[0028] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways than those described herein, and therefore this application is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1, as Figures 1 to 6 As shown, this application provides a cold-drawn flat steel precision drawing die, the die comprising:

[0031] Outer shell 1;

[0032] The support plate 2 is fixedly installed on one side of the outer shell 1, and a connecting bracket 201 is installed on one side of the support plate 2 by screws. The connecting bracket 201 can be removed by rotating the screws, and the flat steel can be processed through the outer shell 1.

[0033] The lead screw 202 is mounted on both sides of the inner wall of the connecting frame 201 via bearings, and a sleeve 203 is threaded on the outer surface of the lead screw 202. When the lead screw 202 rotates in different directions, the sleeve 203 moves to different positions on the outer surface of the lead screw 202.

[0034] The support rod 204 is fixedly installed on both sides of the inner wall of the connecting frame 201, and the slide cylinder 205 is movably sleeved on the outer surface of the support rod 204, and the slide cylinder 205 can slide on the outer surface of the support rod 204.

[0035] A horizontal plate 206 is fixedly mounted on the outer surface of the sleeve 203, and a hollow cylinder 207 is fixedly mounted on one side of the horizontal plate 206. When the horizontal plate 206 moves, it drives the cleaning brush 211 to move.

[0036] like Figures 1 to 6 As shown, an elastic column 208 is movably embedded on one side of the hollow cylinder 207, and a cleaning brush 211 is fixedly installed on one side of the elastic column 208. One side of the horizontal plate 206 is connected to the outer surface of the slide cylinder 205. The cleaning brush 211 moves back and forth on the mold body 304 to clean the debris on the mold body 304.

[0037] like Figures 1 to 6 As shown, a limiting rod 209 is movably embedded on the outer surface of the hollow cylinder 207, and multiple through holes 210 are opened on the outer surface of the elastic column 208. The limiting rod 209 is connected to any one of the through holes 210. By sliding the elastic column 208, the side of the cleaning brush 211 with bristles is pressed tightly against the side of the mold body 304. At this time, the limiting rod 209 is inserted into one of the through holes 210 to fix the position of the elastic column 208.

[0038] like Figures 1 to 6 As shown, a bidirectional motor 212 is installed on one side of the connecting frame 201. The output shaft of the bidirectional motor 212 is connected to the lead screw 202. When the external power switch of the bidirectional motor 212 is turned on, the output shaft of the bidirectional motor 212 can rotate in both directions, thereby driving the lead screw 202 to rotate.

[0039] like Figures 1 to 6 As shown, multiple first telescopic rods 3 are fixedly installed on both sides of the inner wall of the connecting frame 201, and a second telescopic rod 301 is movably embedded on one side of each of the multiple first telescopic rods 3. The multiple second telescopic rods 301 can slide on the inner wall of the multiple first telescopic rods 3 respectively.

[0040] like Figures 1 to 6 As shown, multiple second telescopic rods 301 are arranged in pairs. Each pair of the two sets of second telescopic rods 301 has a fixed plate 302 fixedly installed on one side. Springs 303 are movably sleeved on the outer surface of each of the multiple second telescopic rods 301. When the mold body 304 is placed in the middle of the two fixed plates 302 and the two fixed plates 302 are released, the elastic force generated by the multiple springs 303 squeezes the two fixed plates 302 respectively, so that the two fixed plates 302 clamp the two sides of the mold body 304.

[0041] like Figures 1 to 6As shown, a threaded cylinder 305 is fixedly embedded on one side of one of the connecting brackets 201. A threaded rod 306 is threadedly embedded in the inner wall of the threaded cylinder 305. Rotating the rotating ring 307 clockwise causes the threaded rod 306 to rotate, further causing one end of the threaded rod 306 to move towards the side of the fixed plate 302. When the rotating ring 307 cannot rotate, one side of the threaded rod 306 is pressed against one side of one of the fixed plates 302, so that the two fixed plates 302 fix the mold body 304, completing the installation of the mold.

[0042] like Figures 1 to 6 As shown, a rotating ring 307 is fixedly provided on one side of the threaded rod 306. Rotating the rotating ring 307 causes the threaded rod 306 to rotate, and the rotating ring 307 facilitates the rotation of the threaded rod 306.

[0043] Working principle: When using the mold, multiple second telescopic rods 301 can slide on the inner walls of multiple first telescopic rods 3, pushing two fixed plates 302 respectively. At this time, the mold body 304 is placed in the middle of the two fixed plates 302. When the two fixed plates 302 are released, the elastic force generated by multiple springs 303 squeezes the two fixed plates 302 respectively, so that the two fixed plates 302 clamp the two sides of the mold body 304. Then, rotating the rotating ring 307 clockwise drives the threaded rod 306 to rotate, further causing one end of the threaded rod 306 to move towards one side of the fixed plate 302. When the rotating ring 307 can no longer rotate... When in motion, one side of the threaded rod 306 is pressed tightly against one side of one of the fixing plates 302, so that the two fixing plates 302 fix the mold body 304, completing the mold installation. By rotating the rotating ring 307 counterclockwise, one side of the threaded rod 306 is loosened and pressed against one of the fixing plates 302. At this time, the two fixing plates 302 are pulled to remove the mold body 304 and disassemble the mold. Thus, the mold installation and disassembly method is simple and convenient when using the mold. At the same time, molds of different specifications can be fixed. After the mold finishes processing the flat steel, the external power switch of the bidirectional motor 212 is turned on. The output shaft of the bidirectional motor 212 can rotate in both directions, thereby driving the lead screw 202 to rotate. The slide cylinder 205 can slide on the outer surface of the support rod 204, and the slide cylinder 205 is connected to the sleeve 203 through the cross plate 206. Thus, when the lead screw 202 rotates in different directions, the sleeve 203 moves to different positions on the outer surface of the lead screw 202. At this time, controlling the output shaft of the bidirectional motor 212 to rotate clockwise causes the sleeve 203 to move towards the mold body 304. The elastic column 208 can slide on the inner wall of the hollow cylinder 207, and the elastic column 208 has... The elastic rod 209 is removed from the hollow cylinder 207. By sliding the elastic column 208, the side of the cleaning brush 211 with bristles is pressed against the side of the mold body 304. At this time, the limiting rod 209 is inserted into one of the through holes 210 to fix the position of the elastic column 208. When the horizontal plate 206 moves, it drives the cleaning brush 211 to move. By controlling the output shaft of the bidirectional motor 212 to rotate back and forth, the cleaning brush 211 moves back and forth on the mold body 304 to clean the debris on the mold body 304. Thus, when using the mold, manual cleaning of the mold is not required, improving the efficiency of metal processing.

[0044] The above are merely preferred embodiments and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
