Description

Technical Field

[0001] The utility model relates to the technical field of calendering devices, in particular to a calendering device for producing guide strips. Background Art

[0002] Nonferrous metals usually refer to all metals except iron (sometimes manganese and chromium) and iron-based alloys. Calendering is one of the important basic processes in polymer material processing, and is also one of the important processing and molding methods for semi-finished and finished products of some polymer materials (such as rubber and thermoplastics). In the production and processing of various industrial products such as conductor bars, copper bars, copper rods, and copper parts, a calendering operation is often designed to process metal materials into a flat shape. Metal calendering refers to the process of processing thick metal materials into thinner sheet structures through calendering operations.

[0003] After searching, the Chinese patent announcement number CN213701227U discloses a calendering device for the production and processing of non-ferrous metal guide bars. The patent includes a base, a box body is fixedly installed at the bottom of the base, a first servo motor is fixedly installed on the other side of the top of the box body, a second servo motor is fixedly installed on one side of the top of the box body, the first servo motor and the second servo motor output shaft are fixedly connected with a coupling, a lead screw is fixedly connected at the bottom of the coupling, a slider is fixedly connected on one side of the lead screw, a fixed frame is fixedly installed on both sides of the bottom of the slider, a first calendering roller is fixedly connected on one side of the fixed frame, and a second calendering roller is fixedly installed at the bottom of the base. The device can effectively solve the problem that most calendering devices are difficult to realize the operation of calendering the same material into a variable thickness sheet, and most of the existing calendering devices do not have a push function, need manual operation, and are time-consuming and labor-intensive. It has high practical value, but in the device and the prior art, it is difficult to adjust the calendering wheelbase for calendering work with different requirements, and when the thickness change before and after calendering is too large, it is difficult to ensure a good and uniform calendering effect, and the practicality needs to be improved.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 of the embodiments.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 — Figure 5 As shown, a calendering device for producing guide strips includes a base plate 101, a mounting frame 102 is welded on the base plate 101, a lower pressing roller mechanism is installed on the base plate 101, an upper pressing roller mechanism is arranged in the mounting frame 102, an adjusting mechanism is installed on the mounting frame 102, the upper pressing roller mechanism includes a fixed pressing roller 301 and a plurality of adjusting pressing rollers 302, one end of the fixed pressing roller 301 and the adjusting pressing roller 302 are rotatably connected with a fixed block 303, one side of the fixed block 303 on the adjusting pressing roller 302 is rotatably connected with a sliding block 304 that moves up and down, and the sliding block 304 is used to proportionally adjust the plurality of adjusting pressing rollers 302.

[0025] In this embodiment, the lower pressure roller mechanism includes a power motor 201, which is connected to the top of one side of the base plate 101 by bolts. A synchronous belt 202 is sleeved on the output shaft of the power motor 201, and a power shaft 203 is sleeved on the other end of the synchronous belt 202. The synchronous belt 202 and the power shaft 203 are alternately arranged. The output shaft of the power motor 201 and several power shafts 203 pass through the mounting frame 102 and are connected to the lower pressure roller 204 through a coupling. The setting of the synchronous belt 202 makes the rotation speed of each lower pressure roller 204 the same, so that the travel speed of the guide bar in the mounting frame 102 remains constant.

[0026] In this embodiment, one side of the fixed block 303 on the fixed pressure roller 301 is rotatably connected to a swing plate 305, the top of the swing plate 305 is connected to a pressure plate 306 by bolts, and the sliding block 304 is slidably connected to the bottom of the pressure plate 306. When the swing plate 305 and the pressure plate 306 move, they will swing around the axis of the fixed pressure roller 301 as the center of the circle, and the sliding block 304 is pressed downward by the pressure plate 306 to generate movement.

[0027] In this embodiment, a plurality of equally spaced guide grooves 103 are provided on the mounting frame 102, and the fixed block 303 on the adjusting roller 302 is slidably connected in the guide groove 103. The fixed roller 301 and the end of the adjusting roller 302 away from the fixed block 303 are rotatably connected with a sliding shell 309, and the sliding shell 309 is slidably connected to the inner wall of the mounting frame 102. A power component for driving the fixed roller 301 and the adjusting roller 302 to rotate is installed in the sliding shell 309. Due to the equally spaced arrangement of the guide grooves 103, when the sliding block 304 is driven by the pressure plate 306 to move, the sliding block 304 drives the fixed block 303 on the adjusting roller 302 to move downward, and the downward movement distance of each adjusting roller 302 will increase as the distance from the fixed roller 301 increases, and each adjusting roller 302 is finally adjusted downward in proportion.

[0028] In this embodiment, the adjustment mechanism includes a tooth plate 407 that moves up and down, and the tooth plate 407 is slidably connected to the side of the mounting frame 102. A gear 406 is meshed on one side of the tooth plate 407, and a connecting seat 408 is welded on one side of the tooth plate 407. A sliding shaft 409 is connected to the side of the connecting seat 408 by bolts. The tooth plate 407 is driven by the rotating gear 406 to move downward, the tooth plate 407 drives the connecting seat 408 to move downward, and the connecting seat 408 drives the sliding shaft 409 to move downward.

[0029] In this embodiment, the top of the pressure plate 306 is connected to the connecting plate 307 by bolts, and the end of the top of the connecting plate 307 away from the swing plate 305 is connected to the transmission block 308 by bolts. A groove matching the sliding shaft 409 is opened in the transmission block 308. The sliding shaft 409 slides in the transmission block 308 while moving downward, providing power for the movement of the transmission block 308, thereby pushing the pressure plate 306 and the connecting plate 307 to swing.

[0030] In this embodiment, the adjustment mechanism includes a fixed frame 401, to which an adjustment motor 402 is connected by bolts, and the output end of the adjustment motor 402 is connected to a worm 403 through a coupling, and a worm wheel 404 is meshed on the worm 403. A transmission shaft 405 is connected to one side of the worm wheel 404 by bolts, and the other end of the transmission shaft 405 is connected to a gear 406 by bolts. The transmission shaft 405 is rotatably connected to the inner wall of the fixed frame 401. The cooperation of the worm 403, the worm wheel 404, the transmission shaft 405 and the gear 406 can drive the sliding shaft 409 to move up and down, and when the sliding shaft 409 is subjected to the force transmitted by the upper pressure roller mechanism, it can maintain a stable and immobile state, and has a high pressure-bearing capacity.

[0031] Working principle: before using the device, the final calendering effect is adjusted according to the planned guide strip calendering data. When adjusting, the adjusting motor 402 is turned on, the adjusting motor 402 drives the worm 403 to rotate, the worm 403 drives the worm wheel 404 to rotate, the worm wheel 404 drives the gear 406 to rotate through the transmission shaft 405, the gear 406 drives the tooth plate 407 to move downward, the tooth plate 407 drives the sliding shaft 409 to move downward through the connecting seat 408, and the sliding shaft 409 slides in the transmission block 308 while moving downward, providing power for the movement of the transmission block 308, thereby pushing the pressing plate 306 and the connecting plate 307 to swing, and when the pressing plate 306 swings, it pushes several sliding blocks 304 to move downward, and the sliding block 304 drives the fixed block 303 on the adjusting roller 302 and several adjusting rollers 302 to move downward, and the farther away from the fixed roller 303, the lower the sliding block 304 is. 01, the greater the distance the adjusting roller 302 moves downward, after the adjustment is completed, the distance between the rearmost adjusting roller 302 and the lower pressing roller 204 is the final calendering thickness, and the distances between the remaining adjusting rollers 302 and the lower pressing roller 204 become evenly larger, thereby achieving the effect of gradually and evenly calendering the guide strip. Before using the device, the power motor 201 and the power components in the sliding shell 309 are started, and the power motor 201 drives all the lower pressing rollers 204 to rotate through the power shaft 203, and the fixed pressing roller 301 and the adjusting roller 302 rotate in the opposite direction to the rotation direction of the lower pressing roller 204. The guide strip to be calendered enters the mounting frame 102 from the front end of the fixed pressing roller 301, and is gradually calendered by the lower pressing roller 204, the fixed pressing roller 301 and several adjusting pressing rollers 302, so as to achieve a stable and gradual calendering effect, thereby improving the flatness of the guide strip calendering process.
