Description

Technical Field

[0001] This invention relates to the field of steel formwork welding technology for construction, and particularly to a tooling for processing and welding high-strength alloy steel formwork. Background Technology

[0002] High-strength alloy steel composite formwork has been widely used in modern construction due to its advantages such as high yield strength, high turnover rate, and high construction efficiency. According to the T / CFSA12—2025 standard "High-strength Alloy Steel Composite Formwork", this type of formwork is usually made of alloy steel plates with a yield strength of not less than 500MPa, and the panels, stiffening plates and other components are assembled into a whole through welding.

[0003] In existing technologies, welding fixtures for high-strength alloy steel formwork typically employ fixed or simple mechanical clamping structures. A typical operating procedure is as follows: first, the formwork panel is laid flat on the fixture base; then, the stiffening frame is stacked on top of the panel; finally, the entire assembly is pressed down and fixed using a top pressure plate or cylinder to facilitate welding operations.

[0004] However, this traditional welding fixture has the following significant drawbacks in practical applications: First, due to the large size and heavy weight of the high-strength alloy steel template, the working space is small, positioning is difficult, and the labor intensity is high when workers stack heavy stiffening frames on the already laid panels; second, different batches of templates will have different degrees of warping deformation or dimensional tolerances during processing and transportation. The clamping point of the traditional fixture is fixed and cannot be adaptively adjusted according to the undulations of the workpiece surface. This results in gaps in some areas during welding due to insufficient clamping, affecting the welding quality and failing to meet the strict requirements of template flatness (≤1mm) and dimensional deviation in the T / CFSA12—2025 standard. Summary of the Invention

[0017] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0018] (1) The present invention adopts the method of placing the panel and the stiffening frame in separate positions. Compared with the traditional process of stacking the workpiece on the top of the base frame, the material is received by the backward tilting of the stiffening block, which greatly expands the material loading operation space. The panel and the stiffening frame can be placed at different points at the same time. There is no need to place the panel and the stiffening frame on the top of the base frame components one after another, eliminating the waiting time for placement and significantly improving the clamping efficiency of the workpiece and the smoothness of the welding operation.

[0019] (2) This invention constructs an efficient pressure compensation mechanism by combining the cooperation of the rib clamping block and the clamping arm with the pressure detection feedback at the top of the longitudinal slide. For different batches of workpieces with dimensional tolerances or warping deformation, if the detected value is insufficient when the clamping arm drives the rib clamping block downwards, the rib clamping block can be manually adjusted to extend downwards to compensate for the height difference. If the rib clamping block contacts the high point of the workpiece warping, causing the value to exceed the standard, the rib clamping block can be finely adjusted in the opposite direction to release local stress. This differentiated adjustment method effectively eliminates the influence of workpiece deformation on clamping, ensuring the consistency of clamping force at each point, thereby significantly improving the clamping stability and finished product qualification rate during the welding process.

[0020] (3) After the clamping arm is flipped to the clamping position, the self-locking mechanism is triggered to lock the clamping arm firmly in the preset clamping position. This structural design can transmit the reaction force generated during the welding process to the base frame and the longitudinal slide, forming a stable triangular or multi-point support system, effectively preventing the clamping arm from unexpectedly rebounding or loosening during the welding process. While ensuring that the clamping arm can be flipped, it greatly improves the rigidity of the entire tooling system. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Examples of the clamping operation of high-strength alloy steel molds before welding according to this invention Figures 1-16 As shown, the tilting shaft 203 in the cantilever assembly 2 is laterally screwed to the rear of the top of the base frame component 1 and can rotate automatically within a certain angle range. The top of the base frame component 1 is also arranged with a longitudinal slide 302 slidably connected. The connecting seat 308 is fixed to the top of the rear end of the longitudinal slide 302, and the tilting shaft 203 is inserted in the connecting seat 308. The connecting seat 308 will not interfere with the rotation of the tilting shaft 203. A pressure sensing device is installed at the top of the longitudinal slide 302.

[0043] The rear end of the clamping arm 401 is inserted into the connecting seat 308. The rear end of the clamping arm 401 is equipped with a sliding and sliding locking mechanism relative to the flipping shaft 203, so that the clamping arm 401 can slide relative to the flipping shaft 203 and can also slide and lock. The stiffening plate clamping blocks 403 are arranged and installed in the clamping arm 401, and the stiffening plate clamping blocks 403 can be adjusted up and down. The purpose is to adjust the downward extension length of the stiffening plate clamping blocks 403 based on the pressure sensing device installed at the top of the longitudinal slide 302. After the clamping arm 401 is flipped down to the position, the longer the stiffening plate clamping blocks 403 extend downward, the greater the downward clamping force on the stiffening plate frame.

[0044] Each set of stiffener clamping blocks 403 has an electromagnet 410 installed on the side of the head end of the clamping platform. The external control system can control the on and off of the electromagnet 410, so that when the flipping shaft 203 drives the clamping arm 401 to tilt backward and flip to the receiving angle, the electromagnet 410 is energized to generate magnetic force, which can attract the longitudinal beam of the stiffener frame that has been pre-welded.

[0045] The elastic support frame 502 is slidably connected to the outside of the longitudinal slide 302 by springing upward. Each set of elastic support frames 502 has support wheels 504 installed on both sides of the top end. When there is no external force pushing the support wheels 504, the top end of the support wheels 504 is higher than the top surface of the longitudinal slide 302.

[0046] After the flipping shaft 203 drives the clamping arm 401 to tilt backward and flip to the receiving position, the panel to be welded can be positioned on the top of the base frame component 1.

[0047] Each set of longitudinal slides 302 has a square fixed tube 601 vertically fixed at its front end. A sliding tube 602 is slidably inserted into the square fixed tube 601. A lever mechanism connects the bottom of the sliding tube 602 to the bottom front side of the elastic support frame 502, so that when the elastic support frame 502 descends, the sliding tube 602 rises synchronously, and vice versa. The locking tongue 613 slides backward and is inserted into the top of the sliding tube 602. When the elastic support frame 502 is at its upper limit, the sliding tube 602 is at its lower limit, and the locking tongue 613 retracts into the square fixed tube 601 along with the sliding tube 602. When the flipping shaft 203 rotates, the clamping arm 401 carries the stiffening frame and flips downward. When in position, the bottom of the rib frame is flush with the top of the panel. As the clamping arm 401 flips downward, the clamping block 403 presses down on the rib frame and the panel, overcoming the upward support force of the elastic support frame 502 itself. This causes the support wheel 504 and the elastic support frame 502 to move downward. The downward movement of the elastic support frame 502 causes the sliding tube 602 and the locking tongue 613 to move upward. When the clamping arm 401 flips to the clamping position, the sliding tube 602 moves upward to the head of the locking tongue 613 and engages with the inner hole at the front end of the clamping arm 401. The locking tongue 613 pops outward and passes through the square fixed tube 601 to form a locking engagement with the front end of the clamping arm 401.

[0048] The release mechanism 7 is installed at the top of the square tube 601 and can push and release the locking engagement between the locking tongue 613 and the clamping arm 401.

[0049] The working principle is as follows:

[0050] In the initial state, the clamping component 4 is in the non-clamping position. The flipping shaft 203 drives the clamping arm 401 to tilt backward to the receiving angle, and also drives the rib clamping block 403 to tilt backward together. At the same time, it opens up the space at the top of the open bottom frame component 1.

[0051] The cantilever assembly 2 and the clamping assembly 4 are equipped with a positioning mechanism for placing stiffeners, which allows the operator to place the longitudinal beam of the pre-welded stiffener frame on the head end of the stiffener clamping block 403 at the receiving angle. After the stiffener frame is placed in place, the external control system controls the electromagnet 410 on the side of the head end of the stiffener clamping block 403 to be energized. The electromagnet 410 generates magnetic force to hold the longitudinal beam of the stiffener frame, which can ensure that the stiffener frame remains fixed relative to the clamping arm 401 during the subsequent flipping process, preventing displacement or falling.

[0052] At the same time, the clamping arm 401 tilts back to create space at the top of the bottom frame component 1. The top of the bottom frame component 1 is also equipped with a panel positioning mechanism, which enables the panel to be positioned and placed, so that the rib frame and the panel can be placed in place and the benchmark can be unified.

[0053] Subsequently, the flipping shaft 203 drives the clamping arm 401 of the adsorption rib frame to flip forward and downward. When the bottom of the rib frame contacts the top of the panel, the pressure sensing devices distributed at the top of each longitudinal slide 302 can detect the contact signal.

[0054] As the clamping arm 401 continues to move downward to the clamping position, the rib clamping block 403 presses against the rib frame and panel, overcoming the upward supporting force of the elastic support frame 502 as a whole, pushing the support wheel 504 and the elastic support frame 502 to move downward. The downward movement of the elastic support frame 502 drives the sliding tube 602 to rise synchronously through the lever. When the clamping arm 401 reaches the set clamping position, the sliding tube 602 rises to a specific height, so that the locking tongue 613 is aligned with the inner hole at the front end of the clamping arm 401. Under the support of its own elasticity, the locking tongue 613 pops outward, passes through the square fixed tube 601 and is inserted into the inner hole at the front end of the clamping arm 401, forming a locking and ensuring the stability and reliability of the welding process.

[0055] After the clamping arm 401 moves to the clamping position and is locked by the self-locking mechanism 6, the electromagnet 410 is de-energized, the magnetic force disappears, and the clamping action is performed by the clamping table at the head end of the rib clamping block 403.

[0056] Subsequently, while the self-locking mechanism 6 remains locked, the high-strength alloy steel mold composed of the stiffening frame and the panel is welded. After welding is completed, the release mechanism 7 is controlled by the external control system. The release mechanism 7 moves downward, pushing the locking tongue 613 to overcome the elastic force and retract into the square fixed tube 601, thus releasing the locking tongue 613 from the clamping arm 401.

[0057] After the lock is released, the flip shaft 203 tilts backward and rotates, causing the clamping arm 401 and the rib clamping block 403 to tilt backward to the reset receiving angle. The elastic support frame 502 releases its elastic force to reset, causing the elastic support frame 502 and the support wheel 504 to rise, pushing out the welded overall template. This allows the bottom surface of the panel to detach from the pressure sensor and only roll into contact with the support wheel 504, making it easier for workers to remove the welded overall template and prepare for the next round of welding.

[0058] Furthermore, the manual adjustment of the stiffener clamping block 403 is a compensation mechanism based on pressure feedback. During the processing or pre-welding of high-strength alloy steel templates, there are often certain dimensional tolerances or warping deformations between different batches. When the clamping arm 401 drives the stiffener clamping block 403 to press down onto the workpiece surface, the pressure sensor at the top of the longitudinal slide 302 monitors the clamping force at each point in real time. Since the deformation of different batches of workpieces varies, if the sensor feedback indicates insufficient pressure at a certain point, the operator can manually rotate the stiffener clamping block at the corresponding position based on the reading. 403 extends downwards to compensate for the height difference until the pressure value meets the process requirements; when the stiffener clamping block 403 presses down and contacts the high point of the workpiece warping, the pressure sensor at the top of the longitudinal slide 302 will instantly report an abnormally high pressure value. At this time, the operator should not continue to press down forcibly, but needs to fine-tune the stiffener clamping block 403 at that specific position in the opposite direction to appropriately release the local stress on that high point. Through this adjustment, it is possible to effectively adapt to the batch tolerance of the workpiece and ensure the clamping stability during welding, taking into account both the versatility and reliability of the tooling.

[0059] The specific structures of the base frame component 1, cantilever assembly 2, and pressure sensing module 3 are as follows: Figure 2 , Figure 3 and Figure 4 As shown, the base frame 101 serves as a supporting foundation, with feet 102 evenly fixedly installed at its bottom end, and the cover 103 covers the outside of the base frame 101.

[0060] The reference base 202 is fixed to one side of the top of the base frame 101, and the other side of the top of the base frame 101 is fixed with the base 201. One end of the flip shaft 203 is screwed to the rear end of the reference base 202, and the other end is screwed to the rear end of the base 201.

[0061] A cylinder mounting base 204 is fixed to the bottom of one side of the rear end of the base frame 101. A flipping arm 205 is fixed to one end of the flipping shaft 203. The bottom end of the main body of the flipping cylinder 206 is screwed to the cylinder mounting base 204. The push rod head of the flipping cylinder 206 is screwed to the other end of the flipping arm 205.

[0062] The external control system can control the tilting cylinder 206, and the movement of the push rod of the tilting cylinder 206 drives the tilting arm 205 and the tilting shaft 203 to rotate around the tilting shaft 203.

[0063] One end of the flipping shaft 203 is also fixed with a stiffening plate side stop 208. When the clamping arm 401 tilts backward and flips, the stiffening plate side stop 208 can flip synchronously with the clamping arm 401 to form a side positioning for the placement of the stiffening plate frame.

[0064] The top of the reference base 202 is provided with a right-angled panel reference groove 207, which can position the side and rear of the placed panel.

[0065] Adjustable slide rails 301 are horizontally fixed on both the front and rear sides of the top of the base frame 101. Adjustable sliders 303 are fixed on both sides of the bottom of each set of longitudinal slides 302. The adjustable sliders 303 on the same side are slidably connected to the adjustable slide rails 301.

[0066] A transverse support frame 306 is arranged and fixed between the fixed base 201 and the reference fixed base 202. A clearance sliding groove 309 is opened in the main body of the longitudinal slide 302, which is directly opposite to the transverse support frame 306. The clearance sliding groove 309 on the same side slides with the transverse support frame 306. Both the fixed base 201 and the reference fixed base 202 are provided with a fixing groove 305. The two ends of the transverse support frame 306 are respectively locked in the corresponding fixing groove 305.

[0067] The top surfaces of the longitudinal carriage 302 and the transverse support frame 306 are flush, which can provide support for the panel.

[0068] Each longitudinal slide 302 has a mounting groove 307 at its top. The main body of the longitudinal pressure sensor array 304 is embedded and fixed in the mounting groove 307. In the initial state, the probe of the longitudinal pressure sensor array 304 protrudes from the top plane of the longitudinal slide 302, and the protrusion height is less than or equal to its rated measurement stroke. When the panel in the template is placed on the longitudinal slide 302 and the transverse support frame 306, the bottom surface of the panel abuts against the probe to detect pressure. When the pressure reaches the pre-threshold or the probe is compressed to be flush with the top of the longitudinal slide 302 and the transverse support frame 306, the panel directly abuts against the top of the longitudinal slide 302 and the transverse support frame 306, and the support load is borne by the longitudinal slide 302 and the transverse support frame 306. The longitudinal pressure sensor array 304 will not be subjected to a continuous static load exceeding its range, thus avoiding the risk of crushing.

[0069] The specific structure of the clamping component 4 is as follows: Figure 6 , Figure 7 and Figure 8 As shown, a retaining sleeve 402 is fixedly connected to the rear bottom end of the clamping arm 401. The retaining sleeve 402 is inserted into the connecting screw seat 308. The rib plate crossbar 404 is fixedly connected to the front end of the retaining sleeve 402, which can form a rear end positioning for the placement of the rib plate frame. It cooperates with the rib plate side bar 208 to jointly form the positioning and placement of the rib plate frame.

[0070] The main body of the flip shaft 203 is provided with sliding grooves 405 on both sides. The inner hole of the sleeve 402 is slidably sleeved outside the flip shaft 203. The sliding boss 408 is fixed on the front side of the inner hole of the sleeve 402 and is slidably connected with a set of sliding grooves 405 on the front side. The rear side of the inner hole of the sleeve 402 is provided with a locking slider 406. The locking slider 406 is slidably connected in a set of sliding grooves 405 on the rear side. The locking bolt 407 is threadedly connected to the rear end of the sleeve 402, and the head end of the locking bolt 407 is screwed to the locking slider 406.

[0071] By tightening the locking bolt 407, the sliding state and the locked state of the locking slider 406 in the sliding groove 405 can be switched. When the locking bolt 407 is loosened, the locking slider 406 can slide freely in the sliding groove 405, which allows the clamping arm 401 to be adjusted laterally with the longitudinal slide 302. When the locking bolt 407 is tightened, the locking slider 406 and the sliding groove 405 are locked, which can lock the clamping arm 401 and the longitudinal slide 302 in the current position to adapt to different spacings of the stiffening plate longitudinal beam. The spacing can be adjusted by setting a scale or by setting a fixed length, which will not be listed one by one.

[0072] The stiffening plate is equipped with longitudinal beams and transverse beams. The device is only pressed onto the longitudinal beams. Since the clamping arms 401 are arranged and distributed, the longitudinal beams are also evenly distributed on the stiffening plate frame. Therefore, by pressing the longitudinal beams alone, the stiffening plate frame and the panel can be pressed together.

[0073] The clamping arm 401 is a hollow square tube structure. Clamping adjustment grooves 409 are arranged in its main body. Rib clamping blocks 403 are slidably inserted in the clamping adjustment grooves 409. Each clamping adjustment groove 409 has an adjustment seat 412 on both sides. The adjustment seat 412 is fixedly installed on the top of the clamping arm 401. Side ear seats 411 are fixed on both sides of the rib clamping blocks 403. The bottom end of the side ear seat 411 is locked between the hollow bottom end of the clamping arm 401 and the top spring 413.

[0074] The adjusting bolt 414 is threaded into the adjusting seat 412, and the head of the adjusting bolt 414 is screwed into the side ear seat 411. With the help of a standard tool, the adjusting bolts 414 on both sides of the rib clamping block 403 can be turned simultaneously to adjust the extension height of the rib clamping block 403. Since there is a play in the sliding fit between the rib clamping block 403 and the clamping adjustment slide 409, the extension height of the rib clamping block 403 can be adjusted even if the adjusting bolts 414 on both sides of the rib clamping block 403 are not turned in strict synchronization.

[0075] The specific structures of the elastic support component 5, the self-locking mechanism 6, and the release mechanism 7 are as follows: Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13, Figure 14 and Figure 15 As shown, the U-shaped frame 501 is fixed to the middle of the bottom end of the longitudinal slide 302. Guide slide rails 505 are evenly fixed to both sides of the longitudinal slide 302. Guide sliders 506 are evenly fixed to the inner surfaces of both sides of the elastic support frame 502. The guide sliders 506 on the same side are slidably connected to the guide slide rails 505.

[0076] The support spring 503 is secured between the outer bottom end of the elastic support frame 502 and the inner bottom end of the U-shaped frame 501, enabling the elastic support frame 502 to move freely and elastically upwards without external force.

[0077] Furthermore, the pressing force of the pressing arm 401 can overcome the upward supporting force of the array of support springs 503, pressing the panel in the template to a position where it is in contact with the top surface of the longitudinal slide 302 and the transverse support frame 306. After welding is completed, the pressing arm 401 is released, and the supporting force provided by the support spring 503 is also sufficient to support the support wheel 504 to push the template to a position where the longitudinal slide 302 and the transverse support frame 306 are disengaged.

[0078] The elastic support frame 502 drives the elastic support wheel 504 to cooperate with the rigid support of the longitudinal slide 302 and the transverse support frame 306. In the initial stage of clamping, the support wheel 504 can make slight floating compensation according to the local deformation of the bottom of the panel, so that the stiffener clamping block 403 can fully contact the stiffener longitudinal beam and eliminate the fit gap. When the clamping is in place, the rigid support of the longitudinal slide 302 and the transverse support frame 306 serves as the main load-bearing reference and can effectively resist the vibration and reaction force generated during the welding process, ensuring the absolute stability of the template position. The combination of the two not only ensures the high-precision clamping quality, but also improves the load-bearing rigidity of the overall tooling.

[0079] The active push rod 603 is fixed to the bottom front side of the elastic support frame 502. The bottom front side of the longitudinal slide 302 is fixed with a support rod 604. The bottom of the support rod 604 is fixed with a central shaft 606. The center of the lever 605 is screwed to the central shaft 606.

[0080] The bottom end of the active push rod 603 is screwed with a push roller 607, the bottom end of the sliding tube 602 is screwed with a passive roller 608, the push groove 609 is opened at the rear end of the lever 605, the passive groove 610 is opened at the front end of the lever 605, the push roller 607 is rotatably connected in the push groove 609, and the passive roller 608 is rotatably connected in the passive groove 610;

[0081] A locking wedge 611 is fixed to the bottom of the inner cavity of the front end of the clamping arm 401. A locking tongue sliding hole 612 is opened on the rear side of the top end of the sliding tube 602. The locking tongue 613 is slidably inserted into the locking tongue sliding hole 612. A compression spring retainer 614 is fixed to the inner wall of the front side of the top end of the sliding tube 602. One end of the compression spring 615 is locked to the compression spring retainer 614, and the other end is locked to the locking tongue 613, which can provide the locking tongue 613 with a supporting elastic force towards the clamping arm 401.

[0082] In the initial state, the elastic support frame 502 is at the upper limit position, the sliding tube 602 is at the lower limit position, and the locking tongue 613 retracts into the square fixed tube 601 along with the sliding tube 602. After the rib frame and the panel are positioned and placed, as the elastic support frame 502 moves down, it can drive the active push rod 603 to move down. Using the lever structure formed by the lever 605 and the support rod 604, in conjunction with the rolling connection between the push roller 607 and the push groove 609, and the rolling connection between the passive roller 608 and the passive groove 610, it can drive the sliding tube 602 to move up. When the clamping arm 401 flips to the clamping position, the sliding tube 602 moves up to the position where the locking tongue 613 can just elastically extend out of the side wall of the square fixed tube 601 and form a locking engagement with the locking inclined block 611. By using the inclined surface at the bottom of the locking tongue 613 to engage with the inclined surface at the top of the locking inclined block 611, the locking work of the head end of the clamping arm 401 relative to the longitudinal slide 302 is completed.

[0083] The bottom body of the release cylinder 701 is fixed to the top of the square tube 601. The tail end of the main body of the locking tongue 613 is symmetrically provided with a sliding groove 702. The bottom end of the push rod of the release cylinder 701 is fixed with a release head 703. The bottom end of the release head 703 is symmetrically fixed with a sliding block 704.

[0084] In the initial state, the push rod of the release cylinder 701 is in the upward position. When it is necessary to unlock the latch 613, the external control system controls the release cylinder 701, which drives the push rod of the release cylinder 701 to move downward, so that the two sets of sliding blocks 704 are respectively inserted into the opposite sliding grooves 702. The inclined surface of the lower front end of the sliding block 704 and the inclined surface of the tail end of the sliding groove 702 form a sliding tangential engagement. By moving the push rod of the release cylinder 701 downward, the latch 613 can be driven to retract, releasing the latch 613 from locking the inclined block 611, so that after the stiffening frame and the panel are welded, the clamping arm 401 can be lifted freely.

[0085] Preferably, such as Figure 1As shown, a discharge cylinder 8 is also installed on one side of the base frame 101. After the stiffening frame and the panel are welded, as the clamping arm 401 tilts and flips backward, the stiffening side guard 208 will be lifted through the flipping shaft 203. After the stiffening side guard 208 is lifted, the welded overall template is elastically pushed out by the elastic support frame 502 and the support wheel 504, so that one side of the template is directly opposite the push rod of the discharge cylinder 8. After the external control system starts the discharge cylinder 8, the push rod of the discharge cylinder 8 extends, which can push the welded overall template out laterally, making it convenient for the operator to unload. If an automatic conveying and unloading device is installed on the other side of the base frame 101, the welded overall template can be pushed into the automatic conveying and unloading device to complete the automatic unloading work.
