Vertical take-up line production line line pressing device

Abstract

This invention discloses a vertical take-up production line pressing device, belonging to the technical field of steel bar production lines. It includes a front guide trough B, a rear guide trough B, and a pressing mechanism B. The front guide trough B, pressing mechanism B, and rear guide trough B are connected sequentially along the steel bar conveying direction. The feed end of the front guide trough B is connected to the discharge end of the unloading device, and the discharge end of the rear guide trough B is connected to the feed end of the straightening device. The front guide trough B of one wire pressing unit B is a straight trough, while the front guide trough B of the other wire pressing unit B is an arc-shaped trough. Through this method, the pressing device is designed as an independent structure, separate from other components of the entire vertical take-up system. The arc-shaped trough effectively reduces the poor straightness caused by abnormal wear of mechanical equipment during steel bar production. The lower pressing mechanism B operates stably, is less prone to failing to press the steel bars, significantly reduces wear on rollers and bearings, and decreases the number of downtime due to malfunctions.

Description

Technical Field

[0001] This invention relates to the field of steel bar production line technology, and specifically to a vertical take-up production line pressing device. Background Technology

[0002] When steel bar production stops or during shearing and repacking, the take-up reel continues to rotate due to its rotational inertia. The wire pressing device is used to hold the steel bar in place, stopping the rapid conveying of the cut steel bar under no-tension conditions and preventing the outer layer of the steel bar product from becoming tangled.

[0003] Existing wire pressing devices have the following disadvantages: 1. The bottom support rollers and the pressure rollers are quite long and are both telescopic, resulting in poor stability.

[0004] 2. The upper pressure roller device has only two guide columns, which are located on both sides of the cylinder in a straight line, resulting in uneven force distribution.

[0005] 3. When the steel bar is in the center of the roller assembly, it can be pressed down normally; if the steel bar is on both sides of the roller assembly, due to uneven pressure distribution, it often cannot be pressed down, which leads to abnormal wear of the rollers and damage to the internal bearings.

[0006] Based on this, the present invention designs a vertical take-up production line pressing device to solve the above problems. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a vertical take-up production line pressing device.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A vertical take-up production line pressing device includes a front guide groove B, a rear guide groove B, and a pressing mechanism B; The front guide trough B, the pressing mechanism B, and the rear guide trough B are connected in sequence along the steel bar conveying direction. The feed end of the front guide trough B is connected to the discharge end of the wire feeding device, and the discharge end of the rear guide trough B is connected to the feed end of the straightening device. The front guide groove B of one wire pressing unit B is a straight groove, and the front guide groove B of the other wire pressing unit B is an arc groove. The rear guide groove B of both wire pressing units B are set parallel to the straightening device. The pressing mechanism B includes a frame B, bottom drag fixed rollers, pressing rollers and pressing assembly. The frame B is fixed between the front guide groove B and the rear guide groove B. The pressing assembly is installed at the upper end of the frame B. The pressing rollers are rotatably installed at the output end of the pressing assembly. Multiple bottom drag fixed rollers are rotatably installed at the inner bottom of the frame B.

[0009] Furthermore, multiple bottom drag rollers B are rotatably installed at equal intervals at the bottom of both the straight trough and the arc trough, and bottom drag rollers B are rotatably installed at the bottom of the discharge end of the rear guide trough B.

[0010] Furthermore, multiple side rollers B are equidistantly mounted on the inner arc surface of the arc groove.

[0011] Furthermore, the discharge end of the rear guide trough B is equipped with a pneumatic opening and closing door B.

[0012] Furthermore, inlet-side limiting rollers are symmetrically installed at both ends of the frame B near the front guide channel B, and outlet-side limiting rollers are symmetrically installed at both ends of the frame B near the rear guide channel B.

[0013] Furthermore, the pressing assembly includes a pressing cylinder, a guide column B, and a support plate. The pressing cylinder is fixed to the top of the frame B, and the output end of the pressing cylinder passes through the top of the frame B and is fixed to the support plate. The lower end of the guide column B is fixed to the support plate, and the upper end of the guide column B is slidably connected to the top of the frame B.

[0014] Furthermore, the control guide pillars B of the downward pressure assembly consist of four pillars, and the center point of the output end of the downward pressure cylinder is located at the intersection of the four guide pillars B arranged in an "X" shape.

[0015] Furthermore, the diameter of the arc groove is greater than twelve meters.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: the wire pressing device is set as an independent structure, separated from other components of the entire vertical wire take-up system. Through the arc wire groove, the straightness of the steel bar is effectively reduced due to abnormal wear of mechanical equipment during production. The lower wire pressing mechanism B operates stably and is less likely to fail to press the steel bar. The wear of rollers and bearings is significantly reduced, and the number of downtime due to failure is reduced. It effectively reduces abnormal wear of components in the conductor system, reduces maintenance, and significantly reduces the frequency of maintenance and the amount of spare parts replacement.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0022] In some embodiments, please refer to the accompanying drawings. Figures 1-5The existing vertical take-up system includes a wire feeding device 12 and two vertical take-up modules located at the discharge end of the wire feeding device 12 and capable of working alternately. The vertical take-up module includes a wire pressing unit A2, a straightening device 11 and a take-up device 10 connected in sequence along the steel bar conveying direction. The wire pressing unit A2 includes a pneumatic opening and closing door A21, a front wire groove A22, a rear wire groove A23, a bottom drag roller A24, a rigid guide plate 25, and a pressing mechanism A26. The front wire groove A22, the pressing mechanism A26, and the rear wire groove A23 are connected in sequence along the steel bar conveying direction. The feeding end of the front wire groove A22 is connected to the discharging end of the wire feeding device 12, and the discharging end of the rear wire groove A23 is connected to the feeding end of the straightening device 11. The front wire grooves A22 of the two wire pressing units A2 are arranged in an outward "V" shape, and the rear wire grooves A23 of the two wire pressing units A2 are both arranged parallel to the straightening device 11. Bottom drag rollers A24 are rotatably installed at the bottom of the discharge end of the front guide trough A22. Hard guide plates 25 are symmetrically fixed to the left and right inner walls of the discharge end of the front guide trough A22. Hard guide plates 25 are also fixed to the opposite ends of the rear guide troughs A23 of the two wire pressing units A2. A pneumatic opening and closing door A21 is provided at the discharge end of the rear guide trough A23. The wire pressing mechanism A26 includes a frame A261, a downward pressing movable roller 263, an upward lifting movable roller 264, and a side roller A265. The frame A261 is fixed between the front guide groove A22 and the rear guide groove A23. A set of lifting modules is installed on the upper and lower sides of the frame A261. The output end of the upper lifting module is rotatably mounted with the downward pressing movable roller 263, and the output end of the lower lifting module is rotatably mounted with multiple upward lifting movable rollers 264. The downward pressing movable roller 263 and the upward lifting movable roller 264 cooperate to press the steel bar. Side rollers A265 are rotatably installed on the inner wall of the discharge end of the front wire groove A22 of the two wire pressing units A2. The existing vertical cable take-up system has the following drawbacks: 1. The overall conductor system is shaped like the number eight, with many sharp bends; Second, the steel bar is rigidly guided by the hard impact of the hard guide plate 25 when it passes by. 3. Bottom drag roller A24 is located upstream of the pressing mechanism A26; The above reasons cause the steel rod to easily impact the hard guide plate 25, and the bottom plate of the outlet section of the front guide channel A22 and the rear guide channel A23 to wear.

[0023] Furthermore, the gap between the downward movable roller 263 and the upward movable roller 264 is relatively large, and both are telescopic movable rollers, resulting in poor stability. Also, according to the attached diagram in the instruction manual... Figure 3The lifting module that controls the lifting of the lowering roller 263 has only two guide columns A262. The two guide columns A262 are located on both sides of the cylinder and are in a straight line. When the steel bar is in the center of the roller assembly, it can be pressed down normally. If the steel bar is on both sides of the roller assembly, due to uneven pressure distribution, it often cannot be pressed down, which leads to abnormal wear of the roller and damage to the internal bearing.

[0024] In some embodiments, please refer to the accompanying drawings. Figures 6-10 The present invention improves upon the existing vertical take-up system. The improved vertical take-up system includes a wire feeding device 12 and two vertical take-up modules located at the discharge end of the wire feeding device 12 and capable of working alternately. The vertical take-up module includes a wire pressing unit B3, a straightening device 11, and a take-up device 10 connected in sequence along the steel bar conveying direction; The wire pressing unit B3 includes a pneumatic opening and closing door B31, a front wire groove B32, a rear wire groove B33, a bottom drag roller B34, a side roller B35, and a pressing mechanism B36. The front wire groove B32, the pressing mechanism B36, and the rear wire groove B33 are connected sequentially along the steel bar conveying direction. The feeding end of the front wire groove B32 is connected to the discharging end of the wire feeding device 12, and the discharging end of the rear wire groove B33 is connected to the feeding end of the straightening device 11. The front guide groove B32 of one wire pressing unit B3 is a straight groove, and the front guide groove B32 of the other wire pressing unit B3 is an arc groove with a diameter greater than twelve meters; the rear guide grooves B33 of both wire pressing units B3 are arranged parallel to the straightening device 11. Both the straight trough and the arc trough are equidistantly mounted with multiple bottom drag rollers B34 at their bottoms, and the inner arc surface of the arc trough is equidistantly mounted with multiple side rollers B35 at their bottoms; the bottom of the discharge end of the rear guide trough B33 is equidistantly mounted with bottom drag rollers B34, and the discharge end of the rear guide trough B33 is equipped with a pneumatic opening and closing door B31. The pressing mechanism B36 includes a frame B361, bottom support fixed rollers 362, pressing rollers 363, pressing assembly, inlet side limiting rollers 367 and outlet side limiting rollers 368. The frame B361 is fixed between the front guide groove B32 and the rear guide groove B33. The pressing assembly is installed at the upper end of the frame B361. The pressing rollers 363 are rotatably installed at the output end of the pressing assembly. Multiple bottom support fixed rollers 362 are rotatably installed at the inner bottom of the frame B361. The inlet side limiting rollers 367 are symmetrically rotatably installed at the front and rear ends of the frame B361 near the front guide groove B32. The outlet side limiting rollers 368 are symmetrically rotatably installed at the front and rear ends of the frame B361 near the rear guide groove B33. In this invention, the inlet-side limiting roller 367 and the outlet-side limiting roller 368 work together to fix the swing range of the steel bar when it is being wound up, thereby limiting the movement of the steel bar.

[0025] The pressing assembly includes a pressing cylinder 364, a guide post B365, and a support plate 366. The pressing cylinder 364 is fixed to the top of the frame B361. The output end of the pressing cylinder 364 passes through the top of the frame B361 and is fixed to the support plate 366. The lower end of the guide post B365 is fixed to the support plate 366, and the upper end of the guide post B365 is slidably connected to the top of the frame B361. In this embodiment, the rear guide channel B33 is lengthened, and the width of the feed end of the rear guide channel B33 is smaller than the width of its discharge end. The total length of the rear guide channel B33 is two to three times the total length of the rear guide channel A23.

[0026] In this embodiment, according to the accompanying drawings of the specification Figure 10 The control guide column B365 of the pressing component consists of four columns. The center point of the output end of the pressing cylinder 364 is located at the intersection of the four guide columns B365 arranged in an "X" shape. This reduces abnormal failures of the pressing mechanism B36 and eliminates the phenomenon that the steel rod cannot be pressed down, reducing the possibility of damage to the components of the pressing mechanism B36 and thus reducing the cost of use.

[0027] In this invention, the wire pressing device is set as an independent structure, separated from other components of the entire vertical wire taking system. Through the arc groove, the straightness of the steel bar is effectively reduced due to abnormal wear of mechanical equipment during production. The lower wire pressing mechanism B (36) operates stably and is less likely to fail to press the steel bar. The wear of rollers and bearings is significantly reduced, and the number of downtime due to malfunctions is reduced. The abnormal wear of the conductor system components is effectively reduced, the amount of maintenance is reduced, and the frequency of maintenance and the amount of spare parts replacement are significantly reduced.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
