Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of packing machine equipment, more specifically, it relates to double channel hydraulic shears and the steel bar bundling machine using the hydraulic shears. BACKGROUND

[0002] In traditional industry, the steel bars, shaped steel and the like are often packaged and bundled by manual work with simple tools, and under manual labor condition, it is easy to cause worker fatigue due to high working strength, and it is also possible to cause work injury, which is not conducive to safety production, and also makes the bundling efficiency low and the bundling quality not high. In order to solve these problems, relevant cooperative companies have successively developed and launched many steel bar bundling machines to solve the problem of manual packaging and bundling, and provide automatic configuration for steel bar bundling to improve efficiency.

[0003] On this basis, our company has launched a steel bar bundling machine that can bundle two steel wires for bundling, and has applied for and authorized a Chinese utility model patent for the problem of feeding two steel wires for bundling: (1) A wire feeding mechanism and a steel bar bundling machine using this mechanism, application number 2022234913713, application date December 26, 2022, authorization announcement date July 25, 2023, adopts a design in which fixed parts and moving parts cooperate with each other, and multiple steel bars from the hydraulic shear can enter the internal wire feeding channel, from And expand the scope of application of the baler; (2) an openable and closable wire feeding mechanism and a steel baler using the wire feeding mechanism, application number 2023212446130, application date May 22, 2023, authorization announcement date October 20, 2023, the inner and outer wire feeding channels of the steel baler are replaced with a wire feeding mechanism with controllable opening and closing states, the wire feeding trough and cover of the wire feeding mechanism cooperate to form a closed wire feeding trough and the cover is controlled by a control component to open and close the state; in the outer wire feeding channel, a first fixed component is provided with a second wire feeding mechanism. A movable part, the top of the second movable part is connected to the first movable part, and the bottom of the second movable part is arranged in the wire feeding groove of the second fixed part; when the first movable part moves, it drives the second movable part connected thereto to move, and the bottom of the second movable part located in the wire feeding groove also moves along the wire feeding direction, pushing one or more steel bars for bundling located in the wire feeding groove into the wire feeding channel in the steel bundling machine, thereby expanding the application range of the bundling machine; (3) A damping mechanism and a steel bundling machine using the damping mechanism, application number is 2023213968034, the application date is May 22, 2023, and the authorization announcement is October 20, 2023. A damping mechanism is set on the outside of the twisting robot, including two partitions arranged opposite to each other, and a magnet arranged on the outside of each partition. An extended wire feeding channel is formed between the partitions, which serves as the through hole of the twisting robot and the horizontal extension of the internal wire feeding channel. The adsorption effect of the magnet is used to achieve that the front and rear two bundling steel wires are basically flush and enter the extended wire feeding channel, and then the second moving component jointly pushes the tails of the two wires for wire feeding.

[0004] In actual use, the need to feed two steel wires together through the wire feed channel requires a damping mechanism and magnets for alignment, but this doesn't guarantee foolproof alignment and can lead to a certain failure rate. Furthermore, some customers use copper or aluminum instead of steel wire for bundling, rendering the damping mechanism ineffective. Furthermore, to further improve wire feeding, whether using steel, copper, or aluminum, and to prevent the front and rear wires from jamming or carrying, the straightening performance of the straightener must be enhanced, which undoubtedly increases the difficulty of improving the performance of existing rebar bundling machines.

DETAILED DESCRIPTION

[0037] The technical solution of the present utility model is further described below with reference to specific embodiments.

[0038] The following is an example of a steel bar bundling machine developed by our company that can feed double wires. It should be noted that equipment that can feed double wires and use double wires for bundling can generally also achieve single wire feeding and bundling. Figure 1As shown, the steel bar bundling machine with double wire feeding adopts the structure of the invention patent "Mechanical hand for screwing and bundling" (Patent No. ZL2015103514162, Application Date: June 23, 2015, Authorized Announcement Date: December 26, 2017), and the wire feeding channel is detailed in the Chinese patents "Wire feeding mechanism and steel bar bundling machine using the same" (Application No. 2022234913713, Application Date: December 26, 2022, Authorized Announcement Date: July 25, 2023) and "Openable and closable wire feeding mechanism and steel bar bundling machine using the same" (Application No. 2023212446130, Application Date: May 22, 2023, Authorized Announcement Date: October 20, 2023), and the openable and closable wire feeding channel unit is preferably used to compose the entire wire feeding channel. Whether the wire feeding channel is controlled by the cover plate to be opened or closed, a plurality of openable and closable wire feeding channel units need to be arranged in the wire feeding direction (i.e. from the hydraulic shears to the left clamping working surface of the left rotating arm) to form a basically continuous wire feeding channel, so that the steel bars for bundling enter the horizontally arranged wire feeding channel after entering from the rear end of the bundling machine and being straightened, and then enter the through holes of the left and right clamping working surfaces of the left and right rotating arms. For the convenience of description, the entire wire feeding channel is divided into two components, the section from the screwing mechanical hand to the hydraulic shears is called "outer wire feeding channel", and the section between the left and right rotating arms of the screwing mechanical hand is called "inner wire feeding channel".

[0039] As Figure 2The basic working process of the tying machine is illustrated by taking the tying of the bar steel as an example. Since the cross section of the steel is circular or approximately circular, the steel to be tied from the steel production line is gathered into a bundle, and the cross section of the tied steel is circular or approximately circular. The tying steel passes through the lower part of the bundle, and the left and right ends are arranged in the through holes of the left clamping working surface below the left rotating arm and the right clamping working surface below the right rotating arm, respectively. During the tying process, the left rotating arm and the right rotating arm move upwards, thereby driving the tying steel to move along the left and right ends of the steel to be tied. Since the steel to be tied is gathered into a bundle, the cross section of the tied steel is circular or approximately circular, and the tying steel has small resistance to the steel to be tied. The tying steel can be in good contact (i.e., close fit) with the steel bundle (i.e., the steel to be tied), especially with the bottom or lower surface of the steel bundle. At this time, above the tying steel, the left and right clamping arms drive the left and right clamping working surfaces to clamp and rotate the tying steel into a knot, thereby tying and bundling the gathered steel bundle. In the above-mentioned tying machine, according to the actual needs of the customer, one or two tying steels can be selected to realize the tying of the steel to be tied at the fixed tying position, thereby improving the tying effect. When two tying steels are selected, one of them needs to be cut off first, and the tail of the other steel needs to be cut off to enter the wire feeding channel. At this time, the tail of the first steel in the wire feeding channel is often moved by the second steel, causing the heads and tails of the two steels to be misaligned, which causes serious problems in the tying. Although the previous "damping mechanism and steel tying machine using the damping mechanism" (application number 2023213968034, application date May 22, 2023, authorized on October 20, 2023) can realize the alignment of the two steels, it needs to use a magnet, and the setting of the magnet outside the rotating mechanical hand undoubtedly expands the floor area of the tying machine.

[0040] In the present application, the company no longer uses the above-mentioned external magnet technical solution, i.e., maintaining the floor area of the existing steel tying machine, and improving the hydraulic shear of the single wire feeding channel used by the steel tying machine since 2015-2016 (see Chinese utility model patent "steel hydraulic shear for steel packing machine", application number 2022204061292, application date February 28, 2022, authorized on July 22, 2022).

[0041] As Figure 3As shown, a dual-channel hydraulic shear uses a hydraulic cylinder as the power component. The output shaft of the hydraulic cylinder, serving as the power component's output unit, is positioned generally vertically. The top end of the hydraulic cylinder's output shaft is connected to the bottom end of the transmission component. A sealing component, such as a dust cover, is disposed around the hydraulic cylinder's output shaft, i.e., a dust cover is disposed between the hydraulic cylinder and the transmission component. The hydraulic oil inlet and outlet of the hydraulic cylinder are respectively connected to the oil circuit. The power component drives the transmission component to perform reciprocating motion generally in the vertical direction. A first wire feed channel and a second wire feed channel are disposed in the transmission component along the generally vertical direction (i.e., the direction of reciprocating motion). A clamping component is disposed above the first wire feed channel, and the first wire feed channel is aligned with the wire feed hole of the fixed component. The hydraulic cylinder and fixed component are secured to a base, which is then secured to the baler. The dual-channel hydraulic shear is then mounted on the baler via the base, where the hydraulic shears were previously located. When performing reciprocating motion in the vertical direction, a clamping component is provided above the first wire feeding channel (that is, the clamping component is provided at a position away from the first wire feeding channel in the direction of the reciprocating motion), and when the power component drives the transmission component to perform reciprocating motion (that is, it moves up and down along the basically vertical direction), the clamping end of the clamping component cooperates with the first wire feeding channel to compress the bundling material (that is, the clamping end of the clamping component directly compresses the bundling material), and the clamping end is displaced (that is, it moves upward) relative to the overall clamping component; the clamping end of the clamping component no longer compresses the bundling material, and the clamping end moves and resets under the action of the restoring force, and a unit that provides a restoring force to the clamping end is provided in the clamping component.

[0042] like Figure 3 As shown, in the initial state, that is, when the hydraulic cylinder is not working, the first wire feeding channel is aligned with the wire feeding hole of the fixed component, and the first baling wire (steel wire is still used as an example here, copper wire or aluminum wire is also applicable) passes through the wire feeding hole and enters the first wire feeding channel; when the hydraulic cylinder performs the first section of work, that is, when the output shaft of the hydraulic cylinder moves upward in the vertical direction, the lower edge B of the first wire feeding channel and the upper edge A of the wire feeding hole cooperate with each other to shear and cut the first baling wire, and at the same time, the pressing component presses the cut baling wire in the first wire feeding channel to fix its position. At this time, the second wire feeding channel is aligned with the wire feeding hole, as shown Figure 4 As shown; the second baling steel wire passes through the wire feeding hole and enters the second wire feeding channel, and then the hydraulic cylinder performs the second stage of work, that is, the output shaft of the hydraulic cylinder moves downward in the vertical direction, the upper edge B of the second wire feeding channel and the lower edge A of the wire feeding hole cooperate with each other to shear and cut the second baling steel wire, and the pressing component releases the fixation of the first baling steel wire. At this time, the first baling steel wire is located in the first wire feeding channel, and the second baling steel wire is located in the second wire feeding channel, and the first wire feeding channel is aligned with the wire feeding hole, and the state is restored as shown in FIG. Figure 3 The status shown.

[0043] In the rebar bundling machine, since the straightener previously fed wire to the hydraulic shear while straightening, to ensure bundling quality, the straightener's wire feed length was set based on parameters such as the number and size of the rebar and steel materials to be bundled. When using a dual-channel hydraulic shear to shear the two bundled wires, since the straightener's wire feed length was set to the same, the two bundled wires were essentially the same length, and the wire tails (in the rebar bundling machine, along the wire feed direction from the straightener to the manipulator, the end of the bundled wire facing the straightener is the wire tail, and the end facing the twisting manipulator is the wire head) were essentially flush in the vertical direction.

[0044] In restoring to Figure 3 After the state shown, the straightener continues to feed wire and pushes the first baling wire into the outer wire feeding channel. At this time, the straightener retracts the baling wire to the outside of the wire feeding hole (that is, the subsequent baling wire is retracted to the side close to the straightener), and the output shaft of the hydraulic cylinder moves upward in the vertical direction. When the second wire feeding channel is aligned with the wire feeding hole, the straightener continues to feed wire and pushes the second baling wire into the outer wire feeding channel, and the straightener retracts the wire again; the output shaft of the hydraulic cylinder moves downward in the vertical direction. When the first wire feeding channel is aligned with the wire feeding hole, the straightener feeds wire again, and the hydraulic cylinder continuously moves in the vertical direction to cut the two baling wires. Repeating the operation can achieve continuous operation and ensure that the ends of the baling wires are flush.

[0045] For the shearing operation, the fixed component (including the wire feeding hole provided therein) is equivalent to the fixed knife, and the transmission component (including the first wire feeding channel and the second wire feeding channel provided therein) is equivalent to the movable knife, and both are made of high-hardness and wear-resistant materials so as to perform shearing operations on steel wire, copper wire or aluminum wire used for bundling. For the hydraulic cylinder used, the hydraulic cylinder output amplitude is adjusted according to the position of the wire feeding hole, the clamping component and the positions of the first wire feeding channel and the second wire feeding channel to achieve (1) in the initial state, that is, when the hydraulic cylinder is not working, the first wire feeding channel is aligned with the wire feeding hole of the fixed component; (2) when the hydraulic cylinder performs the first stage of operation, that is, when the output shaft of the hydraulic cylinder moves upward in the vertical direction to the top, the second wire feeding channel is aligned with the wire feeding hole; (3) when the hydraulic cylinder performs the second stage of operation, that is, when the output shaft of the hydraulic cylinder moves downward in the vertical direction to the initial state, the first wire feeding channel is aligned with the wire feeding hole.

[0046] In addition to the above-mentioned use of double wires for baling, the hydraulic shears of the present invention can also be used for single wire (i.e., using one baling material for baling). In the initial position, the first wire feeding channel is aligned with the wire feeding hole of the fixing component, or the second wire feeding channel is aligned with the wire feeding hole of the fixing component:

[0047] (1) The initial position is that the first wire feeding channel is aligned with the wire feeding hole of the fixed part, the baling material passes through the wire feeding hole into the first wire feeding channel, the first section of work is carried out, the power part drives the transmission part to move upward along the vertical direction, the lower edge of the first wire feeding channel and the upper edge of the wire feeding hole cooperate with each other to cut and shear the baling material; the second section of work is carried out, the power part drives the transmission part to move downward along the vertical direction, the cut baling material returns to the position of the initial state, and the first wire feeding channel is aligned with the wire feeding hole, the straightening machine is used for wire feeding to push the first baling material into the outer wire feeding channel, and then the first and second sections of work are repeated to realize single wire use.

[0048] (2) The initial position is that the second wire feeding channel is aligned with the wire feeding hole of the fixed part, the baling material passes through the wire feeding hole into the second wire feeding channel, the first section of work is carried out, the power part drives the transmission part to move downward along the vertical direction, the upper edge of the second wire feeding channel and the lower edge of the wire feeding hole cooperate with each other to cut and shear the baling material; the second section of work is carried out, the power part drives the transmission part to move upward along the vertical direction, the cut baling material returns to the position of the initial state, and the second wire feeding channel is aligned with the wire feeding hole, the straightening machine is used for wire feeding to push the first baling material into the outer wire feeding channel, and then the first and second sections of work are repeated to realize single wire use.

[0049] As for the pressing part, it is arranged above the first wire feeding channel, and a part of it forms a pressing end. When the transmission part moves upward, the pressing end cooperates with the first wire feeding channel to press the first baling steel wire. When the transmission part moves downward, the pressing end resets under the action of the restoring force, i.e. returns to the (original) position of the pressing end when the transmission part has not moved upward. A unit that provides the restoring force to the pressing end is arranged in the pressing part, such as a spring, a spring plate, a hydraulic part, and a pneumatic sealing part.

[0050] As shown in Figs. Figure 3 and 4 , a structure and composition of the pressing part are further illustrated. The pressing part is arranged above the first wire feeding channel and fixed to the top end of the fixed part. The pressing part includes a first cylinder, a lower clamping block, a spring, and an upper clamping block, wherein: the first cylinder is arranged in a substantially vertical direction, and both ends thereof are open. The lower end opening is directed towards the first wire feeding channel, and the other direction is the upper end opening. The upper clamping block, the spring, and the lower clamping block are arranged along the substantially vertical direction from the upper end opening to the lower end opening of the first cylinder.

[0051] One end of the lower clamping block protrudes out of the lower end opening of the first cylinder to form a pressing end for the baling steel wire in the first wire feeding channel, and the other end is arranged inside the first cylinder and connected with the spring. This part of the lower clamping block can move along the inner wall of the first cylinder.

[0052] The upper clamping block is fixedly connected to the first cylinder, and one end of the upper clamping block extends into the interior of the first cylinder and is connected to the spring.

[0053] With this compression structure, the portion of the lower clamping block that extends beyond the lower opening of the first cylinder forms the compression end, directly engaging the baling wire in the first wire feed channel. This portion of the lower clamping block, located within the first cylinder, moves upward. Due to the fixed connection between the upper clamping block and the first cylinder, the spring between the upper and lower clamping blocks compresses. When the hydraulic cylinder drives the transmission component downward, the compressed spring rebounds, resetting the lower clamping block and providing energy for shearing the second baling wire.

[0054] A threaded connection is used between the upper clamping block and the first cylinder, with the other end being substantially flush with the upper opening of the first cylinder. A compression screw is provided on the end of the upper clamping block that is flush with the upper opening of the first cylinder. With this design, the spring acts as if one end of the lower clamping block is active, while the upper clamping block can be adjusted based on conditions (such as the hydraulic cylinder's output distance, the spring's elastic coefficient, the diameter of the baling wire, etc.) through the action of the compression screw. This adjustment allows the upper clamping block to be adjusted vertically via the threaded connection, either entirely extending into the first cylinder or partially extending beyond the upper opening of the first cylinder, thereby coordinating the operation of the spring and the lower clamping block.

[0055] like Figure 5 Another structure and composition of a clamping component shown in the figure is that the clamping component is arranged above the first wire feeding channel and fixed to the top of the fixing component. The clamping component includes a first cylinder, a second cylinder, a lower clamping block, a spring and an upper clamping block. The difference is that the second cylinder is coaxially arranged inside the first cylinder, and the upper clamping block, the spring and the lower clamping block are arranged in the second cylinder in the same manner as before. The adjusting bolts are symmetrically arranged on both sides of the first cylinder and pass through the wall of the first cylinder, acting on the wall of the second cylinder. When adopting this design, the symmetrically arranged adjusting bolts are used to fix the second cylinder to prevent it from moving up and down, and secondly, the entire compression-rebound system composed of the "upper clamping block, spring and lower clamping block" is basically located on the central axis of the first cylinder to enhance the clamping effect. As Figure 5 In the structure shown, a clamping screw is provided on the upper clamping block, and the upper clamping block and the second cylinder are connected by threads, so that the purpose of adjustment is achieved through the action of the clamping screw.

[0056] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other technical personnel in this field without expending creative labor falls within the scope of protection of the present invention.
