Description

Technical Field

[0001] The invention relates to a metal rolling device, in particular to a steel bar welded mesh rolling device and a use method thereof. Background Art

[0002] Welded steel mesh is a mesh structure in which longitudinal and transverse steel bars are arranged at a certain interval and staggered at right angles. The staggered parts of the two steel bars are fixed by welding. The welding parts often produce inconsistent internal stress, which will cause uncontrollable deformation of the welded steel mesh. For this reason, after the steel mesh is welded, it needs to be rolled. The rolling process can not only correct the straightness of the steel mesh, but also further extrude the welding parts of the welded mesh to make its internal structure more compact, thereby improving its strength and toughness.

[0003] However, existing metal rolling devices generally adopt a multi-roller structure, using two adjacent rollers to extrude the metal sheet to achieve the rolling effect. However, the welded steel mesh is not a plate, and its thickness is uneven, especially the thickness of the welding part and the non-welding part changes suddenly. If the welded steel mesh is placed in a roller-type metal rolling device for rolling, the welding part will be introduced into the two rollers. The roller will generate an oblique thrust on the transverse steel bars. This thrust will generate a tensile force that pulls the transverse steel bars apart from the longitudinal steel bars, so the welded steel mesh will have the risk of breaking the weld point. Therefore, the roller-type metal rolling device cannot be used for rolling the welded steel mesh. Summary of the invention

[0004] The invention provides a rolling device for a welded steel mesh, which solves the problem in the prior art that the existing roller-type metal rolling device cannot be applied to the rolling of welded steel meshes.

[0005] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: a rolling device for steel bar welded mesh, comprising: a loading platform, a rolling platform and a unloading platform, the three platforms are distributed in sequence along the Y-axis direction and the upper surfaces are arranged at the same height; a pushing rack and a first reciprocating mechanism that drives the pushing rack to reciprocate along the Y-axis direction are provided on the loading platform, the pushing rack is provided with a pushing plate located above the loading platform, and the length direction of the pushing plate is parallel to the X-axis direction; a hydraulic press and a pressing assembly are provided above the rolling platform, the pressing assembly includes a pressing plate, a pad, a template and a positioning block from bottom to top, the positioning block is directly connected to the hydraulic rod of the hydraulic press, a horizontal supporting plate is provided below the rolling platform, the rolling platform and the supporting plate are horizontally slidably connected, and the sliding direction is parallel to the X-axis direction, and the rolling device also includes a second reciprocating mechanism that drives the rolling platform to reciprocate.

[0006] The loading platform is used to place the steel bar welded mesh to be processed. The first reciprocating mechanism can drive the pusher frame to reciprocate and translate along the Y-axis direction, and has an intermittent equidistant movement effect, so as to achieve the effect of intermittently pushing the steel bar welded mesh to translate to one side of the rolling platform. The distance of each gap movement is fixed, and the distance is approximately equal to the width of the pressing plate; the position of the push plate is divided into a starting position, a plurality of intermediate positions and a stop position, and the reset from the stop position to the starting position is a one-time sliding position, wherein the position of the starting position can be adaptively changed according to the size of the steel bar welded mesh. When loading, the push plate needs to be adjusted to the starting position in advance, so that one side of the steel bar welded mesh is abutted against the push plate. A steel bar welded mesh needs to be rolled several times before it can be completed. The present invention intentionally controls the size of the pressing plate. The larger the area of ​​the pressing plate, the higher the requirements for the overall equipment, and the greater the tonnage requirements of the hydraulic press. The present invention adopts a rectangular pressing plate size, and its length can cover the width of most conventional steel bar welded meshes, and the steel bar welded mesh is rolled by segmented rolling, which can make the invention have excellent versatility.

[0007] At the same time, the present invention also controls the reciprocating movement of the rolling platform along the X-axis direction by setting a second reciprocating mechanism, and the movement method is also intermittent and multi-segment. The purpose of this setting is to allow the force position of the upper surface of the rolling platform to switch positions each time rolling is performed, so as to avoid repeated force at the same position causing excessive wear speed. Excessive wear will cause large deviations in the size of the rolling, which will lead to unqualified products.

[0008] Furthermore, a plurality of rollers are evenly and equidistantly arranged on the support plate, the axial directions of the rollers are parallel to the Y-axis direction, and the bottom surface of the rolling platform is in rolling contact with the rollers; a plurality of constraint wheels are arranged at the bottom of the loading platform and the unloading platform, and the constraint wheels are rollingly fitted on the two side walls of the rolling platform.

[0009] Furthermore, two limit plates are provided on the upper surfaces of the loading platform and the unloading platform, and the length direction of the limit plates is parallel to the Y-axis direction. The spacing between the two limit plates is slightly larger than the width of the steel bar welded mesh. The two limit plates are used to constrain the position of the steel bar welded mesh to ensure that the steel bar welded mesh is located in the center of the loading platform and the unloading platform. If it is not centered for a long time, it will cause uneven force on the lower pressure component for a long time, seriously affecting its service life.

[0010] The present invention also discloses a method for using a rolling device, wherein the rolling device is the rolling device of the steel bar welded mesh described above, and the method for using the rolling device comprises:

[0011] Step 1: Place the steel bar welded mesh to be rolled flat on the loading platform, and ensure that the steel bar welded mesh is located between the two limit plates;

[0012] Step 2: The first reciprocating mechanism drives the push plate to feed backward a fixed distance, thereby pushing the steel bar welded mesh part to move to the rolling platform, and the hydraulic press controls the pressing assembly to press down, rolling and resetting the steel bar welded mesh below, and the second reciprocating mechanism drives the rolling platform to switch position once, and this step is repeated until the steel bar welded mesh is rolled as a whole;

[0013] Step three, remove the steel bar welded mesh from the unloading platform, and the first reciprocating mechanism drives the push plate to reset.

[0014] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention rolls the steel welded mesh by a segmented rolling method. Such a rolling method is not only applicable to the steel welded mesh and ensures a reliable rolling effect, but also enables the present invention to have excellent versatility and be adaptable to steel welded meshes of various sizes; 2. The present invention also controls the rolling platform to reciprocate along the X-axis direction by setting a second reciprocating mechanism. The purpose of such a setting is to ensure that the force position of the upper surface of the rolling platform is switched each time the rolling is performed, so as to avoid repeated force at the same position causing excessive wear speed.

[0025] Example 1: See Figure 1 , Figure 2 and Figure 3 A steel bar welding mesh rolling device comprises: a loading platform 100, a rolling platform 200 and a unloading platform 300, the three platforms are sequentially distributed along the Y-axis direction and the upper surfaces are arranged at the same height; the loading platform 100 is provided with a pushing frame 400 and a first reciprocating mechanism 410 driving the pushing frame 400 to reciprocate along the Y-axis direction, the pushing frame 400 is provided with a pushing plate 420 located above the loading platform 100, and the length direction of the pushing plate 420 is parallel to the X-axis direction; the upper surface of the rolling platform 200 is provided with a pushing plate 420 located above the loading platform 100, and the length direction of the pushing plate 420 is parallel to the X-axis direction; the upper surface of the rolling platform 200 is provided with a pushing plate 420 located above the loading platform 100, and the pushing plate 42 ... A hydraulic press 500 and a pressing assembly 600 are provided. The pressing assembly 600 includes a pressing plate 610, a pad 620, a template 630 and a positioning block 640 from bottom to top. The positioning block 640 is directly connected to the hydraulic rod of the hydraulic press 500. A horizontal supporting plate 700 is provided under the rolling platform 200. The rolling platform 200 and the supporting plate 700 are horizontally slidably connected, and the sliding direction is parallel to the X-axis direction. The rolling device also includes a second reciprocating mechanism for driving the rolling platform 200 to move back and forth.

[0026] The loading platform 100 is used to place the steel bar welded mesh to be processed. The first reciprocating mechanism 410 can drive the pusher frame 400 to reciprocate and translate along the Y-axis direction, and has an intermittent equidistant movement effect, so as to achieve the effect of intermittently pushing the steel bar welded mesh to translate to one side of the rolling platform 200. The distance of each intermittent movement is fixed, and the distance is approximately equal to the width of the pressing plate 610; the position of the push plate 420 is divided into a starting position, several intermediate positions and a stop position, and resetting from the stop position to the starting position is a one-time sliding into place, wherein the position of the starting position can be adaptively changed according to the size of the steel bar welded mesh. When loading, the push plate 420 needs to be adjusted to the starting position in advance so that one side of the steel bar welded mesh is in contact with the push plate 420. A steel bar welded mesh needs to be rolled and pressed multiple times before it can be completed. This embodiment intentionally controls the size of the pressing plate 610. The larger the area of ​​the pressing plate 610, the higher the requirements for the overall equipment, and the greater the tonnage requirement of the hydraulic press 500. This embodiment adopts a rectangular pressing plate 610, the length of which can cover the width of most conventional steel welded meshes, and the steel welded mesh is rolled by segmented rolling, which makes the embodiment have excellent versatility.

[0027] At the same time, this embodiment also controls the reciprocating movement of the rolling platform 200 along the X-axis direction by setting a second reciprocating mechanism, and the movement method is also intermittent and multi-stage. The purpose of this setting is to allow the force position of the upper surface of the rolling platform 200 to switch positions each time rolling is performed, so as to avoid repeated force at the same position causing excessive wear. Excessive wear will cause a large deviation in the size of the rolling, which will lead to unqualified products.

[0028] See Figure 2 and Figure 4 , a plurality of rollers 710 are evenly arranged at the same height on the support plate 700, and the rollers 710 are distributed in two rows, and the axial direction of the rollers 710 is parallel to the Y-axis direction, and the bottom surface of the rolling platform 200 is in rolling contact with the rollers 710; see Figure 6 Three restraining wheels 210 are respectively provided at the bottom of the loading platform 100 and the unloading platform 300 , and the restraining wheels 210 roll and fit on the two side walls of the rolling platform 200 .

[0029] See Figure 5 and Figure 6The second reciprocating mechanism is composed of two servo motors 800 arranged on the loading platform 100 and the unloading platform 300. The servo motor 800 is connected to a constraint wheel 210, specifically a pulley transmission 810, so that the constraint wheel 210 has power and can drive the rolling platform 200 to move by friction. In order to increase the friction, a rubber layer 211 is provided on the outer side of the constraint wheel 210; at the same time, a proximity sensor that can detect the approach of the rolling platform 200 is provided at each end of the supporting plate 700. When the proximity sensor detects that the rolling platform 200 is approaching, it means that the rolling platform 200 has moved to the end of the supporting plate 700. At this time, the control center can control the servo motor 800 to rotate in the opposite direction, so as to realize the autonomous reciprocating motion of the rolling platform 200 within a certain range.

[0030] See Figure 1 , two limit plates 900 are provided on the upper surfaces of the loading platform 100 and the unloading platform 300, and the length direction of the limit plates 900 is parallel to the Y-axis direction. The spacing between the two limit plates 900 is slightly larger than the width of the steel bar welded mesh. The two limit plates 900 are used to constrain the position of the steel bar welded mesh to ensure that the steel bar welded mesh is located in the center of the loading platform 100 and the unloading platform 300. If it is not centered for a long time, it will cause uneven force on the down-pressing assembly 600 for a long time, seriously affecting its service life.

[0031] See Figure 1 and Figure 7 , the loading platform 100 and the unloading platform 300 are both provided with four strip grooves 910 distributed along the X-axis direction, and a fastening bolt 920 is inserted into the strip groove 910 and passes through one end of the limiting plate 900, and a fixed limiting cap 921 and a movable limiting cap 922 are respectively provided at both ends of the fastening bolt 920. When the movable limiting cap 922 is loosened, the limiting plate 900 can move freely along the strip groove 910 to adjust the distance between the two strip grooves 910, and when the movable limiting cap 922 is tightened, the limiting plate 900 is in a fixed state.

[0032] See Figure 1 and Figure 2 Four vertical guide posts 720 are relatively fixed around the supporting plate 700, and the upper ends of the four guide posts 720 are commonly fixedly connected to a positioning plate 730. Four sliding sleeves 740 are provided around the template 630 and are slidably mounted on the four guide posts 720 respectively.

[0033] See Figure 3 A first bracket 110 is provided at the bottom of the loading platform 100 , a second bracket 750 is provided at the bottom of the supporting plate 700 , and a third bracket 310 is provided at the bottom of the unloading platform 300 .

[0034] See Figure 1The first reciprocating mechanism 410 is two servo slides horizontally installed on both sides of the loading platform 100, and the axial direction of the servo slide is parallel to the Y axis.

[0035] This embodiment also discloses a method for using a rolling device, the rolling device is the rolling device of the steel bar welded mesh mentioned above, and the method for using includes:

[0036] Step 1: Place the steel bar welded mesh to be rolled flat on the loading platform, and ensure that the steel bar welded mesh is located between the two limit plates;

[0037] Step 2: The first reciprocating mechanism drives the push plate to feed backward a fixed distance, thereby pushing the steel bar welded mesh part to move to the rolling platform, and the hydraulic press controls the pressing assembly to press down, rolling and resetting the steel bar welded mesh below, and the second reciprocating mechanism drives the rolling platform to switch position once, and this step is repeated until the steel bar welded mesh is rolled as a whole;

[0038] Step three, remove the steel bar welded mesh from the unloading platform, and the first reciprocating mechanism drives the push plate to reset.

[0039] The present invention can be modified in various ways which are obvious to those skilled in the art, and such modifications are not considered to depart from the scope of the present invention. All such modifications which are obvious to those skilled in the art are intended to be included within the scope of the present claims.
