Description

Technical Field

[0001] The invention belongs to the field of flat steel wire winding, and relates to a flat steel wire armor pre-deformation technology, in particular to a flat steel wire armor pre-deformation device and a pre-deformation method. Background Art

[0002] Flat steel wire armor is a process that uses a wire winding machine to wind metal monofilaments (i.e. flat steel wires) around the outside of pipe components to enhance mechanical strength and provide protection.

[0003] During the flat steel wire armoring process, it is often necessary to use a flat steel wire pre-deformation component to pre-twist the flat steel wire so that the flat steel wire and the tube components present a better winding posture, thereby improving the armoring effect of subsequent tube components and avoiding uneven winding and warping.

[0004] The existing Chinese patent publication number CN220515277U proposes a wire twisting mechanism for a flat steel wire winding machine, which is provided with a hollow shaft, a twisting wheel, a twisting guide roller group and a deflection guide roller group, and a gap is formed between the twisting guide roller group and the deflection guide roller group for the flat steel wire to pass through. Therefore, when the twisting wheel rotates, the twisting guide roller group and the deflection guide roller group can rotate relative to each other, thereby completing the pre-twisting deformation of the flat steel wire to change the angle of the flat steel wire, so that the flat steel wire can naturally form a spiral winding on the pipe, thereby ensuring the quality of the flat steel wire winding.

[0005] However, the above device has certain defects: as proposed in the specific implementation of the above patent specification: in the pre-twisting deformation process, the torsion guide roller group and the deflection guide roller group need to be adjusted in advance so that a gap matching the flat steel wire is formed inside both of them for the flat steel wire to limit the position, and then the pre-twisting deformation operation can be performed. Therefore, when facing flat steel wires of different specifications (i.e. thickness) for application, repeated adjustments are required, which causes certain inconveniences in operation.

[0006] Therefore, a flat steel wire armor pre-deformation device and a pre-deformation method are needed to solve the above problems. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a flat steel wire armor pre-deformation device and a pre-deformation method, so that when pre-twisting and deforming flat steel wires of different specifications, the guide roller group can limit the flat steel wire autonomously, that is, there is no need to adjust the guide roller group, thereby reducing the process steps, thereby improving the convenience during use. The present invention is provided with a rotating sleeve, two guide roller groups including a roller frame, a first roller, a second roller and an elastic locking block, and a driving member, and the gap between the second roller and the first roller can be adjusted by moving the elastic locking block and cooperating with the elastic member to meet the needs of passing through flat steel wires of different specifications, and when the elastic locking block is reset, the second roller can be driven to move in a direction close to the first roller, so that when the driving member is separated from the exposed end of the elastic locking block, the second roller and the first roller can autonomously self-lock the flat steel wire, thereby realizing the autonomous limiting of the flat steel wire of the two guide rollers, without the need to manually adjust and lock the guide roller group, thereby reducing the process and improving the convenience during use.

[0008] To achieve the above-mentioned object, a first aspect of the present invention provides a flat steel wire armor pre-deformation device, comprising a support portion, a rotating sleeve, two guide roller groups and a driving member;

[0009] The rotating sleeve is rotatably mounted on one side of the lower surface of the supporting portion;

[0010] The two guide roller groups are symmetrically arranged, one of which is fixedly connected to the rotating sleeve, and the other is fixedly installed on the other side of the lower surface of the support portion, and a channel for the flat steel wire to pass through is formed between the rotating sleeve and the two guide roller groups;

[0011] The guide roller group includes a roller frame, and a first roller, a second roller and an elastic locking block arranged inside the roller frame from bottom to top;

[0012] The second roller is slidably mounted inside the roller frame via an elastic member;

[0013] The elastic locking block is slidably mounted inside the roller frame, is wedge-shapedly connected to the second roller, and has an exposed end extending to the outside of the roller frame;

[0014] When the exposed end is squeezed by an external force to shrink into the roller frame, the second roller moves in a direction away from the first roller through the elastic member;

[0015] When the exposed end is not subjected to external force and is reset, the elastic locking block squeezes the second roller, so that the second roller moves in a direction close to the first roller;

[0016] Wherein, when the exposed end is completely reset and the second roller is lifted in the vertical direction by the elastic force of the elastic member and the external force, the exposed end is in a stationary state, so that the second roller remains locked;

[0017] The driving member is arranged on the supporting portion and is located between the two exposed ends, and is used for being pressed, fitted or separated with the two exposed ends.

[0018] Furthermore, a positioning block is provided on the outer wall of the second roller;

[0019] The elastic locking block is provided with a wedge-shaped groove matching the positioning block;

[0020] The positioning block is always in contact with the wedge-shaped wall of the wedge-shaped groove under the action of the elastic member;

[0021] The restoring elastic force of the elastic locking block is greater than the sum of the elastic force of the elastic member and the force exerted by the pre-twisting of the flat steel wire on the second roller in a direction away from the first roller.

[0022] Furthermore, when the exposed end is contracted by an external force, the positioning block can move to fit with the top wall of the inner cavity of the wedge-shaped groove.

[0023] Furthermore, the upper surfaces of the two exposed ends are both configured as inclined plane cut surfaces;

[0024] Wherein, the cross-sectional areas of the two exposed ends increase successively in the direction away from each other.

[0025] Furthermore, the driving member includes a screw and an extrusion push block;

[0026] The screw is threadedly connected to the extrusion push block;

[0027] The extrusion push block can be fitted with or separated from the inclined plane sections of the two exposed ends at the same time.

[0028] Furthermore, one end of the extrusion push block that contacts the two exposed ends is configured as an isosceles trapezoidal structure.

[0029] Furthermore, a travel switch sensor is provided on the support portion;

[0030] The travel switch sensor is arranged on one side of the extrusion push block and has a contact that is pressed and fitted with the outer wall of the extrusion push block;

[0031] The outer wall of the extrusion push block is provided with a notch recessed along the inner side;

[0032] When the extrusion push block contacts and extrudes the exposed end, the contact is placed in the notch.

[0033] Furthermore, a shifting gear disc is fixedly mounted on the outer wall of the rotating sleeve to drive the rotating sleeve to rotate.

[0034] Furthermore, the shifting gear disc is arranged on the lower surface of the supporting portion;

[0035] A limiting block engaged with the shifting gear disc is slidably installed inside the supporting part along the vertical direction.

[0036] On the other hand, the present invention further proposes a flat steel wire armor pre-deformation method, which uses the flat steel wire armor pre-deformation device described in the above embodiment and specifically includes the following steps:

[0037] The driving member is controlled to be pressed and fitted with the two exposed ends to pull the two exposed ends to move in a direction away from each other, and under the action of the elastic locking block and the elastic member, the second roller in the roller frame moves in a direction away from the first roller to form a gap for the flat steel wire to pass through;

[0038] The operator passes the flat wire through the rotating sleeve and the gap formed in the two guide roller groups in sequence;

[0039] Controlling the driving member to separate from the two exposed ends, so that the elastic locking block is reset, so as to apply a downward squeezing force to the second roller;

[0040] The second roller moves in a direction close to the first roller under the extrusion force to self-lock the flat steel wire, so that the two guide roller groups can autonomously limit the flat steel wire in the corresponding gap;

[0041] The rotating sleeve is driven to rotate, so that the two guide roller groups rotate relatively, and the flat steel wire completes pre-twisting deformation under the limiting action of the two guide roller groups.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] By arranging a rotating sleeve fixedly mounted on one side of the support part, a guide roller group fixed to the rotating sleeve, a guide roller group fixedly mounted on the other side of the support part and a driving member, the guide roller group includes a roller frame, a first roller, a second roller and an elastic locking block arranged from bottom to top inside the roller frame, and the second roller is slid inside the roller frame through an elastic member, and the second roller is wedge-connected to the elastic locking block, so that when the elastic locking block slides, the gap between the second roller and the first roller can be changed under the cooperation of the elastic member, so as to be used for the flat steel wire to pass through or self-lock. During the pre-twisting deformation process of the flat steel wire, the elastic locking block can be pushed to move by the driving member so that the gap between the second roller and the first roller is larger than the thickness of the flat steel wire to allow the flat steel wire to be inserted. After the insertion of the flat steel wire is completed, the elastic locking block is reset by means of the separation of the driving member and the elastic locking block. Therefore, the second roller is autonomously moved in the direction close to the first roller under the wedge-shaped extrusion of the elastic locking block to self-lock the flat steel wire. That is, there is no need to manually adjust the guide roller group to complete the positioning of the flat steel wire, thereby reducing the process steps to improve convenience during use.

[0044] Furthermore, by providing a driving member including a screw and an extrusion push block, a travel switch sensor fitted with the outer wall of the extrusion push block, and a slot opened on the outer side of the extrusion push block, when the extrusion push block moves, the movement and operation of the extrusion push block can be monitored with the help of the travel switch sensor. Since the position of the extrusion push block can determine the movement of the second roller, the relative state between the second roller and the first roller (that is, the second roller moves in a direction close to or away from the first roller) can be indirectly fed back to provide information feedback to the operator, thereby improving the safety of the operator when inserting the flat steel wire.

[0045] Furthermore, by arranging a toggle gear on the outer wall of the rotating sleeve, it is convenient to cooperate with external equipment to adjust the pre-twist angle, and by arranging a limit block on the support part to lock the toggle gear, the change of the pre-twist angle during operation is prevented, thereby improving the accuracy of the pre-twist.

DETAILED DESCRIPTION

[0055] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Embodiment 1

[0057] See also Figures 1 to 4 As shown, an embodiment of the first aspect of the present invention provides a flat steel wire armor pre-deformation device, including a support portion 1, a rotating sleeve 2, two guide roller groups 3 and a driving member 4.

[0058] The rotating sleeve 2 is rotatably mounted on one side of the lower surface of the supporting portion 1 and serves as a power component to pre-twist the flat steel wire.

[0059] In this embodiment, the two guide roller groups 3 are symmetrically arranged, wherein one guide roller group 3 is fixedly connected to the rotating sleeve 2, and the other guide roller group 3 is fixedly installed on the other side of the lower surface of the support portion 1, and a passage for the flat steel wire to pass through is formed between the rotating sleeve 2 and the two guide roller groups 3. When the rotating sleeve 2 rotates, the two guide roller groups 3 can rotate relative to each other, so that the flat steel wire between the two guide roller groups 3 can be pre-twisted and deformed.

[0060] The guide roller set 3 includes a roller frame 31 and a first roller 32 , a second roller 33 and an elastic locking block 34 which are arranged inside the roller frame 31 from bottom to top.

[0061] The second roller 33 is slidably installed inside the roller frame 31 through an elastic member 331 and is located in the same vertical plane as the first roller 32. Therefore, the distance between the second roller 33 and the first roller 32 can be changed by sliding the second roller 33 to meet the demand for passing through flat steel wires of different thicknesses.

[0062] The elastic locking block 34 is slidably mounted inside the roller frame 31 and is wedge-connected with the second roller 33. That is, through the wedge-connection, the movement of the second roller 33 can be controlled by the movement of the elastic locking block 34, so that the gap formed between the second roller 33 and the first roller 32 can be used for the flat steel wire to pass through and also for limiting the position of the flat steel wire.

[0063] The elastic locking block 34 has an exposed end 341 extending to the outside of the roller frame 31, which is convenient for the driving member 4 to synchronously control the two elastic locking blocks 34 to run synchronously to meet the demand for the flat steel wire to pass through.

[0064] Specifically, when the exposed end 341 is squeezed by external force to shrink to the inside of the roller frame 31 (that is, when the two elastic locking blocks 34 move in directions away from each other), the second roller 33 moves in a direction away from the first roller 32 (that is, moves up in a vertical direction) through the elastic member 331, thereby meeting the requirement of the flat steel wire passing through.

[0065] When the exposed end 341 is not subjected to external force and is reset (i.e., the two elastic locking blocks 34 move in a direction approaching each other), the elastic locking block 34 squeezes the second roller 33, causing the second roller 33 to move in a direction close to the first roller 32 (i.e., move downward in a vertical direction) until the second roller 33 completes the clamping and positioning of the flat steel wire with the first roller 32, thereby facilitating the subsequent pre-twisting rotation of the flat steel wire by rotating the sleeve 2. In this process, there is no need for external devices to drive, and the movement of the second roller 33 can be completed only by the elastic force of the elastic locking block 34 itself, thereby achieving the clamping of the flat steel wire, thereby saving the step of manually adjusting and locking the guide roller group 3, so as to achieve the purpose of reducing the number of steps and improving convenience during use.

[0066] In addition, when the exposed end 341 is completely reset and the second roller 33 is lifted in the vertical direction by the elastic force of the elastic member 331 and the external force, the exposed end 341 is in a stationary state, so that the second roller 33 remains locked, so that the self-locking function of the second roller 33 after moving can be realized, ensuring that the second roller 33 can always provide a pressing force on the flat steel wire during the pre-twisting process of the flat steel wire, thereby improving the pre-twisting forming quality of the flat steel wire.

[0067] Among them, the driving member 4 is arranged on the supporting part 1 and is located between the two exposed ends 341, and is used for squeezing, fitting or separating with the two exposed ends 341, that is, the output end of the driving member 4 can fit or separate with the two exposed ends 341, and the contraction or resetting of the exposed end 341 is achieved by changing the relative state between the two, so as to realize the movement control of the second roller 33 and meet the requirements of flat steel wire penetration and pre-twisting deformation.

[0068] The device is provided with a rotating sleeve 2 fixedly mounted on one side of the support part 1, a guide roller group 3 fixed to the rotating sleeve 2, a guide roller group 3 fixedly mounted on the other side of the support part 1 and a driving member 4, and the guide roller group 3 includes a roller frame 31 and a first roller 32, a second roller 33 and an elastic locking block 34 arranged from bottom to top inside the roller frame 31, and the second roller 33 is slid inside the roller frame 31 through an elastic member 331 and the second roller 33 is wedge-connected with the elastic locking block 34, so that when the elastic locking block 34 slides, the gap between the second roller 33 and the first roller 32 can be changed under the cooperation of the elastic member 331, so as to be used for flat steel The wire can be threaded out or self-locked in position. Therefore, during the pre-twisting deformation process of the flat steel wire, the elastic locking block 34 can be pushed to move by the driving member 4, so that the gap between the second roller 33 and the first roller 32 is larger than the thickness of the flat steel wire, so as to allow the flat steel wire to be threaded in. After the threading of the flat steel wire is completed, the elastic locking block 34 is reset by means of the separation of the driving member 4 and the elastic locking block 34. Therefore, the second roller 33 is subject to the wedge-shaped extrusion of the elastic locking block 34 and moves autonomously in the direction close to the first roller 32 to self-lock the flat steel wire in position, that is, there is no need to manually adjust the guide roller group 3 to complete the positioning of the flat steel wire, thereby reducing the process steps to improve the convenience during use.

[0069] like Figure 3 As shown, in this embodiment, a positioning block 332 is provided on the outer wall of the second roller 33 for being wedge-shapedly connected with the elastic locking block 34 .

[0070] Specifically, a wedge-shaped groove 342 matching the positioning block 332 is disposed inside the elastic locking block 34 , and the positioning block 332 is always in contact with the wedge-shaped wall of the wedge-shaped groove 342 under the action of the elastic member 331 .

[0071] It should be pointed out that the reset elastic force of the elastic locking block 34 is greater than the sum of the elastic force of the elastic member 331 and the force exerted by the pre-twisting of the flat steel wire on the second roller 33 in the direction away from the first roller 32, that is, to ensure that during the pre-twisting of the flat steel wire, the second roller 33 will not move in the direction away from the first roller 32 to squeeze the elastic locking block 34 to contract due to the influence of the pre-twisting force and the elastic force of its own elastic member 331, thereby ensuring the self-locking positioning effect of the flat steel wire.

[0072] It should be particularly noted that when the exposed end 341 is contracted by external force, the positioning block 332 can move to fit with the top wall of the inner cavity of the wedge-shaped groove 342, that is, the outer diameter of the wedge-shaped groove 342 decreases from bottom to top, so that when the two elastic locking blocks 34 move away from each other, the positioning block 332 moves upward under the action of the elastic member 331, so as to drive the second roller 33 and the first roller 32 to form a gap for the flat steel wire to pass through, thereby meeting the requirement of the flat steel wire passing through.

[0073] In other embodiments, the shape of the exposed end 341 is further limited so that the driving member 4 can synchronously control the two elastic locking blocks 34 to move in directions away from each other, so as to complete the control of the movement of the second roller 33 .

[0074] Specifically, the upper surfaces of the two exposed ends 341 are both configured as inclined plane sections, wherein the cross-sectional areas of the two exposed ends 341 increase in sequence in the direction away from each other. Therefore, the output end of the driving member 4 can be moved downward to squeeze the inclined plane sections of the exposed ends 341, thereby completing the control of the movement of the two elastic locking blocks 34 in the direction away from each other.

[0075] Preferably, the driving member 4 includes a screw rod 41 and an extrusion push block 42 .

[0076] The screw rod 41 is threadedly connected to the extrusion push block 42 to drive the extrusion push block 42 to move in the vertical direction, so that the extrusion push block 42 can be simultaneously attached to or separated from the inclined plane sections of the two exposed ends 341 .

[0077] The support portion 1 is provided with a limiting groove for limiting the extrusion push block 42 , so that when the screw rod 41 rotates, the extrusion push block 42 moves in the vertical direction under the limiting action of the limiting groove.

[0078] It should be noted that the end of the extrusion push block 42 that contacts the two exposed ends 341 is set to an isosceles trapezoidal structure, and the outer diameter decreases successively from top to bottom. The inclined outer wall of the isosceles trapezoidal structure is used to complete the extrusion of the inclined plane section of the exposed end 341, so as to push the two elastic locking blocks 34 to move in a direction away from each other, thereby completing the movement control of the second roller 33.

[0079] In other embodiments, in order to monitor the operating status of the extrusion push block 42 and facilitate the operator to obtain the information on the relative status between the second roller 33 and the first roller 32 to facilitate the insertion of the flat steel wire or the pre-twisting deformation of the flat steel wire, a travel switch sensor 5 is additionally provided.

[0080] Specifically, a travel switch sensor 5 is provided on the support portion 1 .

[0081] The travel switch sensor 5 is arranged on one side of the extrusion push block 42 and has a contact 51 which is pressed and fitted with the outer wall of the extrusion push block 42 .

[0082] The outer wall of the extrusion push block 42 is provided with a groove 421 recessed along the inner side, so that when the extrusion push block 42 contacts and squeezes the exposed end 341 (i.e., a gap is formed between the second roller 33 and the first roller 32 for the flat steel wire to pass through), the contact 51 is placed in the groove 421.

[0083] When the second roller 33 and the first roller 32 are positioning the flat steel wire, the elastic locking block 34 is in a reset state, so the extrusion push block 42 needs to be separated from the exposed end 341. At this time, the contact 51 of the travel switch sensor 5 will be separated from the slot 421, that is, the relative state between the second roller 33 and the first roller 32 is directly fed back through the change in position between the contact 51 and the slot 421, thereby improving the safety of the operator in inserting the flat steel wire or pre-twisting the flat steel wire.

[0084] In other embodiments, a shifting toothed disc 21 is fixedly mounted on the outer wall of the rotating sleeve 2 for driving the rotating sleeve 2 to rotate, that is, the pre-twisting angle of the flat steel wire is changed by rotating the shifting toothed disc 21 .

[0085] The shifting gear disc 21 is arranged on the lower surface of the support part 1, and a limit block 6 engaged with the shifting gear disc 21 is slidably installed inside the support part 1 along the vertical direction. The shifting gear disc 21 is locked by the limit block 6 to improve the accuracy of pre-twist.

[0086] It should be noted that the movement of the limit block 6 can be driven by a screw rod.

[0087] Embodiment 2

[0088] like Figure 5 As shown, the main difference between this embodiment and the first embodiment is that the shape of the wedge groove 342 is further limited, so that the self-locking function of the flat steel wire can be achieved only by the shape of the wedge groove 342 and the cooperation of the positioning block 332, that is, there is no need to make too many restrictions on the reset elastic force of the elastic locking block 34 and the sum of the pre-twisting force of the elastic member 331 and the flat steel wire, so as to achieve a more stable self-locking effect.

[0089] Specifically, the wedge-shaped groove 342 includes a plurality of trapezoidal grooves connected in the horizontal direction, and the depths of the plurality of trapezoidal grooves increase sequentially from the inside to the outside, and the positioning block 332 is configured as a trapezoidal structure matching the trapezoidal grooves.

[0090] The side of the trapezoidal groove facing away from the resetting direction of the elastic locking block 34 is set as a wedge-shaped wall, and the top wall of the inner cavity is set as a flat section.

[0091] Therefore, when the flat steel wire is placed between the second roller 33 and the first roller 32, the driving member 4 is separated from the exposed end 341, and the elastic locking block 34 is reset, so that the second roller 33 clamps the flat steel wire between it and the first roller 32. At this time, the wedge-shaped wall of the trapezoidal groove will squeeze the positioning block 332, so that the positioning block 332 is engaged with different trapezoidal grooves, so that when the positioning block 332 moves upward under the action of the pre-twisting force, under the action of the flat section and the top wall of the positioning block 332, no component force that pushes the elastic locking block 34 to move in the horizontal direction is formed, so that the second roller 33 can be ensured to be in a locked state, and the self-locking positioning function of the flat steel wire is realized.

[0092] It should be noted that the number and depth of the trapezoidal grooves can be determined according to the model and thickness of the flat steel wire, so that when different flat steel wires are self-lockingly positioned, the positioning block 332 can always engage with one of the trapezoidal grooves to ensure the self-locking positioning effect of the flat steel wire.

[0093] Embodiment 3

[0094] like Figure 6 As shown, this embodiment further proposes a flat steel wire armor pre-deformation method based on the first embodiment, using the flat steel wire armor pre-deformation device described in the first embodiment, and specifically includes the following steps:

[0095] The driving member 4 is controlled to be pressed and fitted with the two exposed ends 341 to pull the two exposed ends 341 to move in a direction away from each other, and under the action of the elastic locking block 34 and the elastic member 331, the second roller 33 in the roller frame 31 moves in a direction away from the first roller 32 to form a gap for the flat steel wire to pass through;

[0096] The operator passes the flat steel wire through the gap formed by the rotating sleeve 2 and the two guide roller groups 3 in sequence;

[0097] Control the driving member 4 to separate from the two exposed ends 341, so that the elastic locking block 34 is reset to apply a downward squeezing force to the second roller 33;

[0098] Under the extrusion force, the second roller 33 moves in the direction close to the first roller 32 to self-lock the flat steel wire, so that the two guide roller groups 3 can autonomously complete the positioning of the flat steel wire in the corresponding gap;

[0099] The rotating sleeve 2 is driven to rotate, so that the two guide roller groups 3 rotate relatively, and the flat steel wire completes the pre-twisted deformation under the limiting action of the two guide roller groups 3.

[0100] Through the above steps, when the flat steel wire needs to be positioned, it is only necessary to control the driving member 4 to separate from the exposed end 341 so that the elastic locking block 34 is reset, and the second roller 33 and the first roller 32 are controlled under the extrusion action to complete the clamping of the flat steel wire, thereby achieving the limitation of the flat steel wire. Therefore, in the above process, there is no need to manually adjust the two rollers on the guide roller group 3, thereby achieving the purpose of reducing the process steps and improving the convenience during use.

[0101] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
