Description

Technical Field

[0001] This invention relates to the field of press technology, and more specifically, to a high-rigidity press frame based on prestressed steel wire winding and its winding fixture. Background Technology

[0002] As the core equipment for forging and stamping, the rigidity, compressive strength and structural stability of the press frame directly determine the processing accuracy, load capacity and service life of the equipment. High rigidity frames are the core components of large-tonnage, high-precision presses. Prestressed steel wire winding process has become the mainstream manufacturing process for high-end press frames because it can offset the alternating load during the operation of the frame and improve the overall rigidity of the frame through the pre-tension of the steel wire.

[0003] In existing technologies, the prestressed steel wire winding of press frames mostly adopts an integral winding groove design, with the steel wire wound in a single groove along the side wall of the frame. Although this can form a basic preload, it still has defects. When a steel wire ages and breaks at a certain point, the entire wound steel wire will loosen, instantly losing its fastening effect on the frame. This causes a sudden drop in the overall rigidity and compressive strength of the frame, and the entire wound steel wire needs to be replaced, which is quite troublesome. If the integral steel wire winding is improved to multi-segment winding, although it can solve the problem that the impact of a broken steel wire at a certain point on the overall preload is not significant, conventional winding fixtures cannot achieve the turning and connection of steel wires between different grooves. At the turning point, multiple steps such as bending, positioning, temporary fixing, cutting, and permanent fixing of steel wires need to be completed manually. The low precision of manual operation can easily lead to the steel wires at the turning point becoming loose, offset, or pulling on each other, which can disrupt the continuity of the prestressing layout. This makes the actual rigidity of the frame much lower than the design value, and the manual operation steps are cumbersome, which greatly reduces the winding processing efficiency. In view of this, we propose a high-rigidity press frame based on prestressed steel wire winding and its winding fixture. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention designs a winding adjustment mechanism in the winding fixture. When the frame body is wound in the first stage, i.e., the steel wire is wound in the lower winding groove, the steel wire is guided by the wire tube and the horizontal steel wire fastening channel to perform the winding operation. When the first stage of winding is completed and the upper winding groove needs to be wound, the railcar moves to the point where the locking wedge is aligned with the winding groove on the side wall of the frame body and stops moving. Then, the tube frame rotates eccentrically, causing the locking wedge to rotate, so that the steel wire fastening channel changes from a horizontal state to an inclined state. The steel wire fastening channel bends the steel wire into an inclined state. At this time, the locking wedge can be aligned with the shape of the winding groove on the side wall of the frame body. By moving the moving frame forward, the locking wedge is inserted into the winding groove on the side wall of the frame body. Then, the tightening assembly fixes the locking wedge to the side wall of the frame body with bolts. The punching assembly fastens the steel wire on the two clamping units. The steel wires within the channel are cut and separated, completing the fixation of the end wire of the first-stage winding and the starting wire of the second-stage winding. Subsequently, the components of the winding adjustment mechanism are reset, and the steel wires continue to be guided through the guide tube for the second-stage winding operation in the upper winding groove. This achieves uninterrupted, high-precision turning winding of the steel wires from the lower winding groove to the upper winding groove, allowing the winding trajectories of the two stages of steel wires to conform to the groove structure of the main body of the frame, forming a continuous and layered prestressed layout. At the same time, the fixing of the locking wedge and the cutting and separation of the steel wires achieve independent fastening and limiting of the upper and lower winding steel wires, preventing the steel wires from loosening, shifting, or pulling each other at the turning point. This design solves the problem in the prestressed steel wire winding process where the turning connection of steel wires between different grooves of the main body of the frame is difficult, and the steel wires at the turning point need to undergo multiple steps of bending, positioning, fixing, and cutting, which conventional winding fixtures cannot achieve.

[0016] 2. This invention designs a wire-locking wedge, consisting of two sets of clamping units, which can simultaneously clamp and fix the wire at the end of the lower winding groove and the wire at the beginning of the upper winding groove. During winding, the clamping block is held and fixed by the clamping components, maintaining a fixed angle so that the wire fastening channel remains horizontal. The horizontal wire fastening channel is in a naturally expanded state, ensuring normal output winding of the wire. When the drum frame rotates eccentrically, it drives the wire-locking wedge to rotate, causing the wire fastening channel to change from a horizontal state to an inclined state. When the wire fastening channel bends the wire into an inclined state, the moving frame moves forward and inserts the base block into the winding groove on the side wall of the main frame. Then, the tightening assembly fixes the fastening clamp to the side wall of the main frame with bolts. At this time, the distance between the fastening clamp and the base block decreases, the wire fastening channel contracts, and the wire is squeezed and clamped. This achieves a firm lock on the two sections of wire at the end of the lower winding groove and the beginning of the upper winding groove. The locking action is completed simultaneously with the installation and fixing of the locking wedge, without the need for additional clamping operations. This allows the positioning and fixing of the wire after turning and bending to be integrated into one operation.

[0017] 3. This invention designs an arc-shaped protrusion on the punching head, which, in conjunction with the pressure head on the push plate, allows the punching head to move slowly forward within the punching groove when the three output ends of the cylinder advance slowly. The arc-shaped protrusion on the punching head and the concave arc structure of the pressure head form a locking engagement. The limiting post at the top of the pressure rod remains within the straight section of the T-groove, locking the pressure rod's vertical displacement. This ensures a stable locking state between the pressure head and the arc-shaped protrusion. The slow forward movement of the punching head within the punching groove allows the pressure head to drive the push plate and slide forward, thereby achieving the effect of fixing the locking wedge to the side wall of the frame body using bolts. After the bolt tightening operation is completed, the limiting post moves synchronously from the straight section of the T-groove to the T-shaped area. At this point, the pressure rod releases its vertical movement lock, and the three output ends of the cylinder continue their rapid forward stroke, driving the punching head forward rapidly within the punching groove, punching out of the groove. The steel wires in the wire fastening channels of the two clamping units are rapidly punched to separate the two sections of steel wire. During this process, the pushing column of the punching head drives the arc-shaped protrusion to move rapidly and synchronously. The rapid displacement of the arc-shaped protrusion creates an outward pushing force on the pressure head. This pushing force overcomes the elastic force of the spring and pushes the pressure rod to slide outward along the insertion direction of the push plate. At the same time, the limiting column at the other end of the pressure rod moves upward in the T-shaped area of ​​the T-slot. The clamping engagement between the pressure head and the arc-shaped protrusion is released, and the punching head no longer drives the push plate and the slide to move. Instead, it continues to move forward rapidly to complete the stroke. This structure only needs to slowly move forward through the three output ends of the cylinder, and then quickly move forward to complete the forward tightening operation of the tightening component and the cutting operation of the steel wire by the punching head in sequence. There is no need to control the action sequence of the two components separately, which reduces the control steps of the tooling and improves the efficiency of fixing and cutting operations at the turning point of the steel wire.

[0018] 4. This invention also features a slot on the side wall of the arc-shaped protrusion and a retaining plate designed on the side wall of the concave arc structure at the bottom of the pressure head. After the punching operation is completed, the three output ends of the cylinder drive the punching head back, the push column drives the arc-shaped protrusion to move in the opposite direction, and the arc-shaped protrusion is re-pressed into the concave arc structure at the bottom of the pressure head, pushing the pressure rod to compress the spring upward, so that the limiting column moves upward and resets in the T-shaped area of ​​the T-slot until it is aligned with the straight section of the T-slot. At the same time, the retaining plate can form a locking engagement with the slot. During the continued return of the punching head, the locking engagement between the retaining plate and the slot drives the pressure rod. The movement causes the limiting post to slide back into the straight section of the T-slot, forming a axial lock on the pressure rod. This locking structure simultaneously drives the push plate and slide to retreat along the original path. The slide then drives the sliding column to reset along the tightening groove. The rotating handle also disengages from the bolt and returns to its initial position, completing the linkage reset of the tightening and punching components. This effectively solves the problem that in the initial stage of the return stroke, because the limiting post is in the T-shaped area of ​​the T-slot, the pressure rod can still move up and down, and the arc-shaped protrusion can easily squeeze through the unlocked pressure head, making it impossible to drive the push plate and slide to retreat along the original path.

[0035] Example 1, as Figures 1 to 2 As shown, this embodiment provides a high-rigidity press frame based on prestressed steel wire winding, including a frame body 1. The frame body 1 has a winding groove on its side wall. The winding groove is used as a load-bearing structure to cooperate with the prestressed steel wire winding process. A reinforcing plate 101 is arranged on the side wall of the winding groove. The reinforcing plate 101 is a strip-shaped reinforcing rib structure. The reinforcing plate 101 can enhance the overall compressive strength of the frame. The reinforcing plate 101 divides the winding groove into a lower winding groove 102 and an upper winding groove 103. The side wall of the reinforcing plate 101 has a dividing groove 104, an inclined groove and multiple screw holes. The dividing groove 104 divides the inclined groove into a lower inclined groove 105 and an upper inclined groove 106. After the frame body 1 is prestressed by winding steel wire through the winding groove, the winding steel wire is divided into two parts and wound in an orderly manner in layers. The connection between the two parts of the steel wire can be fixed in the lower inclined groove 105 and the upper inclined groove 106 by the locking wedge block 72. The connection between the two parts of the steel wire can be cut by the dividing groove 104, so that the two parts of the steel wire form relatively independent parts. The winding steel wire of the two independent parts together form a fastening effect on the frame body 1. This solves the problem that the traditional winding steel wire is an integrated structure. When a steel wire ages and breaks, the entire winding steel wire will loosen and instantly lose its fastening effect on the frame body 1, causing a sudden drop in the overall rigidity and compressive strength of the frame. Moreover, the entire winding steel wire needs to be replaced, which is more troublesome.

[0036] Example 2, as Figures 3 to 15 As shown, this embodiment provides a winding fixture for manufacturing the above-mentioned high-rigidity press frame based on prestressed steel wire winding. It includes an annular ground rail 2, and a positioning support seat 3 is arranged inside the annular ground rail 2. The positioning support seat 3 is used to position and support the frame body 1. A railcar body 4 is movably arranged on the top of the annular ground rail 2. The railcar body 4 can move in an annular path on the annular ground rail 2 to form a movement around the frame body 1 on the positioning support seat 3, so that the steel wire can be wound around the winding groove on the side wall of the frame body 1 during steel wire winding. The railcar body 4 includes a lifting platform 401 that can be lifted and lowered. The lifting platform 401 is a conventional cylinder-driven lifting structure.

[0037] In an embodiment of the present invention, a wire feeding frame 5 and a winding adjustment mechanism 6 are installed on the top of the lifting platform 401. The wire feeding frame 5 is used to output steel wire, and the winding adjustment mechanism 6 is used to guide the output steel wire. When the steel wire is wound, the wire feeding frame 5 and the winding adjustment mechanism 6 can be driven to move synchronously around the frame body 1 by the closed-loop movement of the railcar 4 on the annular ground rail 2. This allows the steel wire output by the wire feeding frame 5 to be wound in an orderly manner along the winding groove on the side wall of the frame body 1 under prestress. At the same time, the lifting adjustment of the lifting platform 401 can be used to adapt to the winding position of the winding groove of the frame body 1 at different heights.

[0038] In an embodiment of the present invention, the winding adjustment mechanism 6 includes a movable frame 602 slidably arranged on the top of the lifting platform 401, and a cylindrical frame 7 movably arranged on the side wall of the movable frame 602; a clamping assembly 71 and a wire locking wedge 72 are arranged on the side wall of the cylindrical frame 7, and a wire tube 73 is also connected to the side wall of the cylindrical frame 7; a tightening assembly 74 and a punching assembly 75 are arranged in the inner cavity of the cylindrical frame 7; the clamping assembly 71 is used to clamp and fix the wire locking wedge 72; the tightening assembly 74 is used to fix the wire locking wedge 72 to the side wall of the frame body 1 by bolts; the wire locking wedge 72 is composed of two sets of clamping units, and the clamping unit includes a wire fastening channel 7205, which can be contracted to form a clamping state for the wire; the punching assembly 75 is used to cut and separate the wire in the wire fastening channel 7205 on the two clamping units; the cylindrical frame 7 can rotate eccentrically, synchronously driving the wire locking wedge 72 to rotate, so that the wire fastening channel 7205 rotates from a horizontal state to an inclined state.

[0039] This invention incorporates a winding adjustment mechanism 6 within the winding fixture. During the first stage of winding the frame body 1, i.e., when the wire is wound in the lower winding groove 102, the wire is guided by the wire tube 73 and the horizontal wire fastening channel 7205 for output guidance during the winding operation. When the first stage of winding is complete and winding of the upper winding groove 103 is required, the railcar 4 stops moving when the locking wedge 72 aligns with the winding groove on the side wall of the frame body 1. Subsequently, the winding is completed via the tube frame 7... An eccentric rotation is performed, causing the wire locking wedge 72 to rotate, which in turn causes the wire fastening channel 7205 to rotate from a horizontal state to an inclined state. The wire fastening channel 7205 bends the wire into an inclined state. At this time, the wire locking wedge 72 can be aligned with the winding groove shape on the side wall of the frame body 1. The moving frame 602 moves forward to insert the wire locking wedge 72 into the winding groove on the side wall of the frame body 1. Then, the tightening assembly 74 fixes the wire locking wedge 72 to the side wall of the frame body 1 with bolts. The punching assembly 75 then... The steel wires in the wire fastening channels 7205 on the two clamping units are cut and separated, completing the fixation of the end wire of the first stage winding and the starting wire of the second stage winding. Then, the components of the winding adjustment mechanism 6 are reset, and the wires are guided by the guide tube 73 to carry out the winding operation of the upper winding groove 103 in the second stage. This achieves uninterrupted and high-precision turning winding of the steel wire from the lower winding groove 102 to the upper winding groove 103, so that the winding trajectory of the two stages of steel wires fits the groove structure of the side wall of the frame body 1 to form a continuous and layered prestressed layout. At the same time, the fixing of the locking wedge block 72 and the cutting and separation of the steel wires achieve independent fastening and limiting of the upper and lower winding steel wires, avoiding the loosening, displacement or mutual pulling of the steel wires at the turning point. This design solves the problem that in the prestressed steel wire winding process, the steel wires between different grooves of the frame body 1 are difficult to connect and turn, and the steel wires at the turning point need to be bent, positioned, fixed and cut in multiple steps. Conventional winding fixtures are difficult to achieve this complex process.

[0040] In an embodiment of the present invention, the winding adjustment mechanism 6 further includes a cylinder 601 installed on the top of the lifting platform 401. The output end of the cylinder 601 is connected to the side wall of the moving frame 602, and the moving frame 602 is moved forward or backward and reset through the cylinder 601.

[0041] In an embodiment of the present invention, a second cylinder 603 is installed on the top of the movable frame 602, and a rotating rod 604 is rotatably arranged on the side wall of the movable frame 602. One end of the rotating rod 604 is connected to a drive plate 605, and the other end is eccentrically connected to the side wall of the cylindrical frame 7. The drive plate 605 has a drive groove 606 on its side wall, and a U-shaped frame 607 is connected to the output end of the second cylinder 603. A drive column 608 is connected to the inner side wall of the U-shaped frame 607, and the drive column 608 is movably arranged in the drive groove 606. When cylinder 603, acting as a power source, extends and retracts, it simultaneously drives the U-shaped frame 607 at its output end to move linearly. The U-shaped frame 607, along with the drive column 608 on its inner sidewall, slides within the drive groove 606 on the sidewall of the drive plate 605. The sliding of the drive column 608 creates a pushing and pulling force on the drive plate 605, which in turn drives the rotating rod 604 connected to the drive plate 605 to rotate around the sidewall of the moving frame 602. The end of the rotating rod 604 away from the drive plate 605 is eccentrically connected to the sidewall of the tube frame 7. Therefore, the rotation of the rotating rod 604 drives the tube frame 7 to complete eccentric rotation, ultimately achieving angle adjustment of the tube frame 7 and components such as the locking wedge block 72 on the frame, thereby adjusting the horizontal and tilt states of the wire fastening channel 7205.

[0042] In an embodiment of the present invention, the clamping unit includes a base insert 7201 and a fastening clamp 7202. Multiple sliding rods 7203 are connected to the side wall of the base insert 7201. The sliding rods 7203 movably pass through the side wall of the fastening clamp 7202. A limiting plate 7204 is connected to the end of each sliding rod 7203. The limiting plate 7204 is arranged to the side of the fastening clamp 7202. The base insert 7201 moves relative to the fastening clamp 7202 via the multiple sliding rods 7203. The limiting plate 7204 limits the stroke of this relative movement, allowing only a small range of movement between the base insert 7201 and the fastening clamp 7202. This ensures that the steel wire in the steel wire fastening channel 7205 can be output normally, preventing the steel wire from being clamped by the steel wire fastening channel 7205 during winding, thus affecting the winding process.

[0043] Furthermore, both the base insert 7201 and the fastening clamp 7202 have groove structures on their side walls, forming a wire fastening channel 7205 between the groove structure of the base insert 7201 and the groove structure of the fastening clamp 7202. When the base insert 7201 and the fastening clamp 7202 are not subjected to external force, they can move relative to each other and form a loose state. At this time, the wire fastening channel 7205 is in a naturally expanded state, which can ensure the normal output and winding of the wire. Both symmetrical side walls of the fastening clamp 7202 have multiple slots 7206 with the same structure.

[0044] This invention designs a wire-locking wedge 72, which consists of two clamping units. These units simultaneously clamp and fix the wire at the end of the winding in the lower winding groove 102 and the wire at the beginning of the winding in the upper winding groove 103. During winding, the clamping block 7202 is held and fixed by the clamping assembly 71, maintaining a fixed angle so that the wire fastening channel 7205 remains horizontal. The horizontal wire fastening channel 7205 is in a naturally expanded state, ensuring normal output winding of the wire. When the drum frame 7 rotates eccentrically, it drives the wire-locking wedge 72 to rotate, causing the wire fastening channel 7205 to change from a horizontal to an inclined state. When the wire fastening channel 7205 bends the wire into an inclined state, the moving frame... 602 moves forward, inserting the base insert 7201 into the winding groove on the side wall of the frame body 1. Then, the tightening assembly 74 fixes the fastening clamp 7202 to the side wall of the frame body 1 with bolts. At this time, the distance between the fastening clamp 7202 and the base insert 7201 is reduced, and the wire fastening channel 7205 contracts, squeezing and clamping the wire. This achieves a firm lock on the two sections of wire at the winding end of the lower winding groove 102 and the winding start of the upper winding groove 103. The locking action is completed synchronously with the installation and fixing of the locking wedge 72, without the need for additional clamping operations. This allows the positioning and fixing of the wire after turning and bending to form an integrated operation. At the same time, the independent locking of the two sets of clamping units also provides a stable structural foundation for the subsequent cutting and separation of the two sections of wire by the punching assembly 75.

[0045] In an embodiment of the present invention, the clamping assembly 71 includes a fixing block 7101 connected to the side wall of the cylinder frame 7, and a lower clamping plate 7102 and an upper clamping plate 7103 slidably arranged on the side wall of the cylinder frame 7. The fixing block 7101 is arranged between the lower clamping plate 7102 and the upper clamping plate 7103. Multiple insert rods 7104 of the same structure are connected to the side walls of both the lower clamping plate 7102 and the upper clamping plate 7103. A fastening clamping block 7202 of one clamping unit can be clamped between the lower clamping plate 7102 and the fixing block 7101, and a fastening clamping block 7202 of another clamping unit can be clamped between the upper clamping plate 7103 and the fixing block 7101. The insert rods 7104... 04 is used to insert into the slot 7206 to form a locked state; wherein, the side wall of the cylinder frame 7 is provided with multiple movable slots 7106, punching slots 7107 and multiple tightening slots 7108, the punching slots 7107 penetrate through the side wall of the fixing block 7101; the inner side wall of the cylinder frame 7 is provided with a moving unit 7105, the moving unit 7105 is a motor-driven bidirectional screw moving mechanism, the two moving ends of the moving unit 7105 can move towards or away from each other by rotating the bidirectional screw, one of the moving ends is connected to the side wall of the lower clamping plate 7102 through the movable slot 7106, and the other moving end is connected to the side wall of the upper clamping plate 7103 through the movable slot 7106. When the two moving ends of the moving unit 7105 move synchronously in opposite directions or in opposite directions, they can drive the lower clamping plate 7102 and the upper clamping plate 7103 to slide synchronously in opposite directions or in opposite directions on the side wall of the cylinder frame 7. When the lower clamping plate 7102 and the upper clamping plate 7103 slide towards the fixed block 7101, the fastening clamping blocks 7202 of the two sets of clamping units can be clamped on both sides of the fixed block 7101. At the same time, the insert rods 7104 on the lower clamping plate 7102 and the upper clamping plate 7103 will be inserted into the slots 7206 of the fastening clamping block 7202 to form a lock, thereby achieving a stable clamping of the wire locking wedge 72. When the two slide in opposite directions, the clamping and locking states are released, and the wire locking wedge 72 can be separated.

[0046] In an embodiment of the present invention, the punching assembly 75 includes a support frame 7501 connected to the inner side wall of the cylinder frame 7. A cylinder 3 7502 is installed on the side wall of the support frame 7501. The output end of the cylinder 3 7502 is connected to a punching cutter head 7503. The punching cutter head 7503 is movably arranged in the punching groove 7107. The punching cutter head 7503 has a clearance groove 7504 from top to bottom. The bidirectional lead screw of the moving unit 7105 is arranged in the clearance groove 7504. No matter whether the punching cutter head 7503 is performing a stroke or a return stroke, the bidirectional lead screw is always located in the clearance groove 7504 to avoid motion interference.

[0047] In an embodiment of the present invention, the tightening assembly 74 includes a slide 7401 slidably arranged on the inner circumference of the cylindrical frame 7. A rotary motor 7402 is mounted on the side wall of the slide 7401. A drive gear 7403 is connected to the output end of the rotary motor 7402. A gear ring 7404 is rotatably arranged on the inner circumference of the slide 7401. The drive gear 7403 meshes with the teeth of the gear ring 7404. A plurality of sliding columns 7405 are connected to the side wall of the slide 7401. The sliding columns 7405 are slidably arranged in the tightening groove 7108. A plurality of rotating handles 7406 are rotatably arranged on the side wall of the sliding columns 7405. The end of the rotating handle 7406 is a hexagonal wrench structure for tightening bolts. The other end of the rotating handle 7406 passes through the side wall of the sliding column 7405 and is connected to a driven gear 7407. The driven gear 7407 meshes with the teeth of the gear ring 7404. When the rotating motor 7402 is working, it can drive the gear ring 7404 to rotate. The gear ring 7404 drives multiple driven gears 7407 to rotate. The driven gears 7407 drive the coaxially connected handle 7406 to rotate. When the handle 7406 rotates, it moves forward in conjunction with the slide 7401. The hexagonal wrench structure at the end of the handle 7406 can screw the bolt from the side wall of the fastening clamp 7202 into the screw hole on the side wall of the reinforcing plate 101. This achieves the effect of reducing the distance between the fastening clamp 7202 and the base insert 7201, shrinking the wire fastening channel 7205, squeezing and clamping the wire, and fixing the fastening clamp 7202 to the side wall of the reinforcing plate 101.

[0048] In an embodiment of the present invention, the punching head 7503 includes a push column 7505, and two symmetrically distributed arc-shaped protrusions 7506 are connected to the side wall of the push column 7505; the support frame 7501 has a moving groove 7508 on its side wall, and the support frame 7501 includes a plurality of guide plates 7509, and the side wall of the guide plates 7509 has a T-shaped groove 7510; the carriage 7401 includes a push plate 7408, which is movably arranged in the moving groove 7508, and the side wall of the push plate 7408 has a circular groove 7409, in which the push column 7505 is spaced apart; a plurality of pressure rods 7410 are movably inserted into the side wall of the push plate 7408, one end of the pressure rod 7410 extends into the circular groove 7409 and is connected to a pressure head 7411, and the other end is connected to a limiting post 7412, which is movably arranged in the T-shaped groove 7506. Inside 510, a limiting block 7413 is connected to the side wall of the pressure rod 7410. The limiting block 7413 is movably arranged in the inner cavity of the push plate 7408, and the top of the limiting block 7413 is connected to the side wall of the inner cavity of the push plate 7408 by a spring 7414. When the arc-shaped protrusion 7506 separates from the pressure head 7411, the limiting block 7413 is driven by the elastic force of the spring 7414 to move the pressure rod 7410 downward. The lower limit of the lower movement of the limiting block 7413 in the inner cavity of the push plate 7408 can ensure that the lower limit of the lower movement of the pressure head 7411 forms a gap with the side wall of the push column 7505, avoiding the pressure head 7411 from sticking to the side wall of the push column 7505 and generating frictional resistance to the movement of the push column 7505. The bottom of the pressure head 7411 is a concave arc structure, and the pressure head 7411 can form a snap-fit ​​with the arc-shaped protrusion 7506 through the concave arc structure. This invention utilizes an arc-shaped protrusion 7506 designed on the punching head 7503, in conjunction with the pressure head 7411 on the push plate 7408. When the output end of the cylinder 7502 slowly advances forward, it drives the punching head 7503 to slowly move forward within the punching groove 7107, before the punching operation begins. At this time, the arc-shaped protrusion 7506 on the punching head 7503 and the concave arc structure of the pressure head 7411 form a snap-fit ​​engagement, and the limiting post 7412 at the top of the pressure rod 7410 remains within the straight section of the T-groove 7510, locking the vertical displacement of the pressure rod 7410. This ensures a stable snap-fit ​​between the pressure head 7411 and the arc-shaped protrusion 7506, while the punching head 7503 slowly moves forward within the punching groove 7107, thus enabling the punching to pass through... The pressure head 7411 drives the push plate 7408 and the slide 7401 forward, which in turn drives the sliding column 7405 on the slide 7401 to move forward synchronously along the tightening groove 7108. The forward movement of the sliding column 7405 will cause the hexagonal wrench end of the rotating handle 7406 to precisely fit against the bolt on the side wall of the fastening clamp 7202. At this time, the rotating motor 7402 starts synchronously, and drives the gear ring 7404 to rotate through the drive gear 7403. The gear ring 7404 meshes and drives multiple driven gears 7407 to rotate synchronously, which in turn drives the rotating handle 7406 to rotate, screwing the bolt from the side wall of the fastening clamp 7202 into the screw hole of the reinforcing plate 101 of the frame body 1, completing the fixation of the fastening clamp 7202. At the same time, it reduces the distance between the fastening clamp 7202 and the base insert 7201, and the wire fastening channel 7205 retracts and clamps the steel wire. After the bolt tightening operation is completed, the limiting column 7412 moves synchronously from the straight section area of ​​the T-slot 7510 to the T-shaped area. At this time, the pressure rod 7410 releases its locking mechanism for vertical movement, and the output end of cylinder 3 7502 continues to make a rapid forward stroke, driving the punching head 7503 to move rapidly forward in the punching groove 7107. It punches out of the punching groove 7107 and rapidly punches the steel wire in the steel wire fastening channel 7205 of the two clamping units, realizing the cutting and separation of the two sections of steel wire. During this process, the pushing column 7505 of the punching head 7503 will drive the arc-shaped protrusion 7506 to move synchronously and rapidly. The rapid displacement of the arc-shaped protrusion 7506 will generate an outward pushing force on the pressure head 7411. This pushing force overcomes the spring 74 The elastic force of the spring 7410 pushes the pressure rod 7410 to slide outward along the insertion direction of the push plate 7408. The pressure rod 7410 drives the limit block 7413 to compress the spring 7414. At the same time, the limiting post 7412 at the other end of the pressure rod 7410 will move upward in the T-shaped area of ​​the T-slot 7510. The engagement between the pressure head 7411 and the arc-shaped protrusion 7506 is released. The punching head 7503 no longer drives the push plate 7408 and the slide 7401 to move, but continues to move forward quickly to complete the stroke. This structure only needs to slowly move forward through the output end of the cylinder 3 7502, and then quickly move forward to complete the forward tightening operation of the tightening component 74 and the cutting operation of the punching head 7503 in the stroke. There is no need to control the action sequence of the two components separately.This reduces the number of control steps in the tooling and improves the efficiency of fixing and cutting operations at the turning points of the steel wire.

[0049] In an embodiment of the present invention, the side wall of the arc-shaped protrusion 7506 is provided with a slot 7507, which is a right-angled slot structure. The concave arc structure side wall of the bottom of the pressure head 7411 is connected to a retaining plate 7415. When the punching head 7503 is in the stroke, the retaining plate 7415 can separate from the slot 7507. When the punching head 7503 is in the return stroke, the retaining plate 7415 can engage with the slot 7507.

[0050] The present invention also provides a slot 7507 on the side wall of the arc-shaped protrusion 7506 and a retaining plate 7415 on the concave arc structure side wall at the bottom of the pressure head 7411. After the punching operation is completed, the output end of the cylinder 7502 drives the punching head 7503 to return, and the push column 7505 drives the arc-shaped protrusion 7506 to move in the opposite direction. The arc-shaped protrusion 7506 is re-pressed into the concave arc structure at the bottom of the pressure head 7411, and pushes the pressure rod 7410 to compress the spring 7414 upward, so that the limiting column 7412 moves upward in the T-shaped area of ​​the T-shaped groove 7510 to be aligned with the straight section area of ​​the T-shaped groove 7510. At the same time, the retaining plate 7415 can form a snap-fit ​​with the slot 7507. During the return of the punching head 7503, the snap-fit ​​between the retaining plate 7415 and the slot 7507 drives the pressure rod 7411 to return. 410 moves, thereby causing the limiting post 7412 to slide back into the straight section of the T-slot 7510, forming a reset axial lock on the pressure rod 7410. Through this locking structure, the push plate 7408 and the slide 7401 are simultaneously driven to retreat along the original path. The slide 7401 drives the sliding post 7405 to reset along the tightening groove 7108. The rotating handle 7406 also disengages from the bolt along with the slide 7401 and returns to the initial position, completing the linkage reset of the tightening assembly 74 and the punching assembly 75. This effectively solves the problem that in the initial stage of the return stroke, because the limiting post 7412 is in the T-shaped area of ​​the T-slot 7510, the pressure rod 7410 can still move up and down, and the arc-shaped protrusion 7506 is easy to squeeze through the unlocked pressure head 7411, resulting in the inability to drive the push plate 7408 and the slide 7401 to retreat along the original path through the pressure head 7411.

[0051] Example 3: This example provides a working method for a winding fixture based on a high-rigidity press frame using prestressed steel wire winding, including the following steps: S1. Initial preparation operation: The main body of the frame 1 is placed on the positioning support seat 3 by the hoisting equipment to complete the positioning support. The wire end output from the wire feeding frame 5 is passed through the wire tube 73 and the wire fastening channel 7205 of the two sets of clamping units in sequence. Then, the lower clamping plate 7102 and the upper clamping plate 7103 are slid towards each other by the moving unit 7105 to clamp and fix the wire locking wedge 72 on both sides of the fixing block 7101. The insertion rod 7104 is inserted into the slot 7206 to form a lock. The wire output from the wire fastening channel 7205 is fixed to the winding starting point of the winding groove 102 of the lower winding groove 1 of the main body of the frame 1 by external bolts and other tools. S2. In the first stage of winding operation, the lifting platform 401 is adjusted to match the height of the lower winding groove 102 of the frame body 1. The railcar 4 is controlled to move in a circle along the circular ground rail 2. The wire feeding frame 5 outputs steel wire. The steel wire is guided along the horizontal steel wire fastening channel 7205 and prestressed winding is carried out on the lower winding groove 102. During the winding process, the lifting platform 401 adapts to the reciprocating lifting of the lower winding groove 102 to form multi-layer winding. S3. Wire bending operation: After the winding of the lower winding groove 102 is completed, control the railcar body 4 to move until the locking wedge block 72 is aligned with the winding groove of the frame body 1 and stop. Start the cylinder 603 to drive the tube frame 7 to rotate eccentrically, so that the wire fastening channel 7205 changes from horizontal to inclined, and bends the wire to the angle that matches the inclined groove. S4. Base insert operation: Start cylinder 601 to push the moving frame 602 forward, and insert the two base inserts 7201 of the rotated locking wedge 72 into the lower inclined groove 105 and upper inclined groove 106 of the side wall reinforcing plate 101 of the main frame 1. S5. Tightening operation: Start cylinder 7502 to slowly advance the punching head 7503. The arc-shaped protrusion 7506 engages with the pressure head 7411 and drives the slide 7401 forward. At the same time, start the rotating motor 7402 to drive the rotating handle 7406 to rotate. The hexagonal wrench end of the rotating handle 7406 precisely fits the bolt on the side wall of the fastening clamp 7202, screws the bolt into the screw hole of the reinforcing plate 101 to form a fixation, and the distance between the fastening clamp 7202 and the base insert 7201 decreases, and the wire fastening channel 7205 contracts to clamp the wire. S6. Punching operation: After the bolts are tightened, the limiting column 7412 moves synchronously from the straight section of the T-slot 7510 to the T-shaped area. At this time, the pressure rod 7410 is released from its vertical movement lock, and the output end of the cylinder 7502 continues to make a rapid forward stroke, driving the punching head 7503 to move rapidly forward in the punching groove 7107, punching out of the punching groove 7107 to quickly punch the wire in the wire fastening channel 7205 of the two clamping units, realizing the cutting and separation of the two sections of wire. During this period, the pushing column 7505 of the punching head 7503 will drive the arc-shaped protrusion 7506 to move rapidly and synchronously. The rapid displacement of 506 will generate an outward pushing force on the pressure head 7411. This pushing force overcomes the elastic force of the spring 7414 and pushes the pressure rod 7410 to slide outward along the insertion direction of the push plate 7408. The pressure rod 7410 drives the limiting block 7413 to compress the spring 7414. At the same time, the limiting post 7412 at the other end of the pressure rod 7410 will move upward in the T-shaped area of ​​the T-shaped groove 7510. The locking and engagement state between the pressure head 7411 and the arc-shaped protrusion 7506 is released. The punching head 7503 no longer drives the push plate 7408 and the slide 7401 to move, but continues to move forward rapidly to complete the wire cutting and separation operation independently. S7. Reset operation: Start cylinder 3 7502 drives the punching head 7503 to return, the clamping plate 7415 engages with the clamping groove 7507, drives the slide 7401 to retreat and reset along the original path, the rotating handle 7406 disengages from the bolt, the moving unit 7105 drives the lower clamping plate 7102 and the upper clamping plate 7103 to slide in opposite directions, releasing the clamping of the locking wedge block 72, then cylinder 1 601 controls the moving frame 602 to reset, and cylinder 2 603 controls the cylinder frame 7 to reset. S8. Second-stage winding operation: Adjust the lifting platform 401 to match the height of the winding groove 103 on the main frame 1, control the railcar 4 to continue moving in a circle along the circular ground rail 2, and output the wire from the wire feeding frame 5. Guided by the wire tube 73, the prestressed wire winding on the upper winding groove 103 is completed. After the upper winding groove 103 is completed, cut the wire and fix the wire end in the preset fixed position on the main frame 1 to complete the prestressed wire winding operation of the entire main frame 1.
