Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic roll welding equipment for roll welding machines, and more particularly to the field of automatic production of concrete pipe piles, specifically referring to a segmented rebar pipe and rebar plate device. Background Technology
[0002] The reinforcing cage used in pipe piles is an important component of pipe piles. It is formed by welding together the main reinforcing bars distributed around the circumference and the spiral bars surrounding the main reinforcing bars using a roll welding machine. After the subsequent process of adding head and tail end plate assemblies, the assembled reinforcing cage assembly is placed in the pipe pile mold. After processes such as material laying, inserting the reinforcing cage into the mold, closing the mold, and applying prestress, a usable prestressed pipe pile is finally formed.
[0003] Before the automatic welding of cage reinforcement bars by the roller welding machine, the main reinforcement bars of the required specifications need to be transported to the material pick-up position of the reinforcement bar threading equipment through uncoiling, cutting, upsetting, flipping, buffer sorting and conveying equipment. Finally, the automatic reinforcement bar threading machine grabs the main reinforcement bars and transports them to the reinforcement bar threading fixture of the roller welding machine according to the preset program. In order to meet the automatic reinforcement bar threading function, the roller welding machine must have a reinforcement bar threading plate fixture that allows the automatic reinforcement bar threading machine to thread the main reinforcement bars. Since there are many specifications of cage reinforcement bars, such as round piles with specifications of φ300~φ1000 and square piles with specifications of φ300~φ700, in order for the automatic reinforcement bar threading machine to complete the automatic reinforcement bar threading according to the required specifications, the corresponding specification of the reinforcement bar threading plate fixture needs to be made.
[0004] Currently, the rebar threading mechanism used in roll welding machines to meet the automatic rebar threading function of automatic rebar threading machines is an integral rebar threading mechanism. An important component of this mechanism, the rebar threading tube, is also an integral welding assembly. When changing models, the entire rebar threading plate needs to be replaced before production can begin. Furthermore, after a period of use, friction wear occurs between the main reinforcing steel bar and the inner wall of the rebar threading tube. When the wear reaches a certain level, the worn rebar threading tube needs to be replaced. However, the integral rebar threading tube is difficult to disassemble and assemble. The mounting bolts of the rebar threading tube need to be removed before the entire rebar threading tube can be pulled out and replaced. This is also relatively costly. The entire tooling change process is cumbersome and carries the risk of injury from falling heavy objects when using a crane. The changeover time is also long, resulting in low production efficiency. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a segmented rebar threading pipe and rebar threading disc device that meets the requirements of low maintenance cost, high replacement efficiency, and wide applicability.

[0007] The main features of this segmented rebar threading and rebar threading disc device are as follows: the device includes a frame assembly and a segmented rebar threading disc; the lower base plate of the frame assembly is mounted on a welding machine; the upper end of the frame assembly is connected and fixed to the segmented rebar threading disc; the segmented rebar threading disc includes a front rebar threading disc, a rear rebar threading disc, multiple segmented rebar threading assemblies, a locking sleeve, a locking bushing, and a connecting block; the multiple segmented rebar threading assemblies are connected between the front and rear rebar threading discs; the locking sleeve is installed at the outer center of the front and rear rebar threading discs; the locking bushing is installed at the center of the locking sleeve; one end of the connecting block is installed on the front rebar threading disc, and the other end is installed on the frame assembly; the segmented rebar threading disc is connected and fixed to the upper end of the frame assembly via the connecting block.
[0008] Preferably, the segmented reinforcing tube assembly includes a head end assembly, a guide tube middle section, and a guide tube end section. Multiple head end assemblies are welded to the surface of the front reinforcing plate. One end of the guide tube middle section is inserted and installed on the head end assembly, and the guide tube end section is inserted and installed on the other end of the guide tube middle section. Multiple guide tube ends are installed on the surface of the rear reinforcing plate. The guide tube middle section and the guide tube end section are detachable.
[0009] Preferably, the segmented reinforcing pipe assembly further includes a plunger, which is mounted on the middle section of the guide pipe.
[0010] Preferably, a ball is installed inside the plunger, and the rear through-rib plate is engaged with the ball.

[0012] This invention utilizes a segmented rebar threading device and rebar threading disc. By optimizing the rebar threading disc structure and the rebar threading component structure, the overall tooling weight is reduced to approximately half of the previous weight. This enables rapid disassembly and installation of the rebar threading component, facilitating quick model changeovers. No crane assistance is required during model changeovers; a single worker can complete the tooling replacement, reducing changeover time by two-thirds and improving overall changeover efficiency, thereby increasing production efficiency.

[0048] To more clearly describe the technical content of this utility model, the following description is provided in conjunction with specific embodiments.
[0049] This utility model discloses a segmented rebar threading device, including a frame assembly 1.1 and a segmented rebar threading disc 1.2. The lower base plate of the frame assembly 1.1 is mounted on a welding machine, and the upper end of the frame assembly 1.1 is connected and fixed to the segmented rebar threading disc 1.2. The segmented rebar threading disc 1.2 includes a front rebar threading disc 2.1, a rear rebar threading disc 2.2, multiple segmented rebar threading assemblies 2.3, a locking sleeve 2.4, a locking bushing 2.5, and a connecting block 2.6. The segmented threading tube assembly 2.3 is connected between the front threading plate 2.1 and the rear threading plate 2.2. The locking sleeve 2.4 is installed at the outer center of the front threading plate 2.1 and the rear threading plate 2.2. The locking bushing 2.5 is installed at the center of the locking sleeve 2.4. One end of the connecting block 2.6 is installed on the front threading plate 2.1 and the other end is installed on the frame assembly 1.1. The segmented threading plate 1.2 is connected and fixed to the upper end of the frame assembly 1.1 through the connecting block 2.6.
[0050] In a preferred embodiment of this utility model, the segmented reinforcing tube assembly 2.3 includes a head end assembly 3.1, a guide tube middle section 3.2, and a guide tube end 3.3. Multiple head end assemblies 3.1 are welded to the surface of the front reinforcing plate 2.1. One end of the guide tube middle section 3.2 is inserted and installed on the head end assembly 3.1, and the guide tube end 3.3 is inserted and installed on the other end of the guide tube middle section 3.2. Multiple guide tube ends 3.3 are installed on the surface of the rear reinforcing plate 2.2. The guide tube middle section 3.2 and the guide tube end 3.3 are detachable.
[0051] In a preferred embodiment of the present invention, the segmented reinforcing pipe assembly 2.3 further includes a plunger 3.4, which is installed on the middle section 3.2 of the guide pipe.
[0052] In a preferred embodiment of this utility model, a ball is installed inside the plunger 3.4, and the rear through-rib plate 2.2 is secured to the ball.
[0053] In a preferred embodiment of this utility model, the rear reinforcing bar plate 2.2 has a combination of circumferential holes of various reinforcing bar specifications. The combination of circumferential holes of various reinforcing bar specifications includes a circular through hole 2.2.1.1 or a waist-shaped hole 2.2.1.2 for reinforcing bars. The segmented reinforcing bar tube assembly 2.3 is inserted into the circular through hole 2.2.1.1 or the waist-shaped hole 2.2.1.2 for reinforcing bars.
[0054] This utility model is mainly applied in the field of automatic production technology of concrete pipe piles, and in particular relates to a segmented rebar threading assembly, which is a component of the segmented rebar threading plate 1.2. It is a component of a rebar threading fixture on an automatic roll welding machine. The purpose is to enable quick switching of production models in the rebar threading fixture holes of different cage rebar specifications when the same set of rebar threading fixtures is compatible with the production of 3 to 4 rebar specifications. This can be achieved by quickly disassembling, installing, and replacing some parts of the rear rebar threading assembly, thus achieving compatibility with various cage rebar specifications and models and enabling flexible production of various different cage rebars.
[0055] In a specific embodiment of this utility model, the bottom plate of the frame assembly 1.1 is installed together with the roll welding machine, and the upper part is connected and fixed to the segmented rebar threading plate 1.2. The automatic rebar threading machine grabs the main rebar bars and threads the main rebar bars into the corresponding rebar threading tubes according to the preset program, thereby realizing the automatic rebar threading function.
[0056] The segmented threading plate 1.2 is composed of a front threading plate 2.1, a rear threading plate 2.2, a segmented threading tube assembly 2.3, a locking sleeve 2.4, a locking bushing 2.5, and a connecting block 2.6, and is connected and fixed to the upper part of the frame assembly 1.1 through the locking sleeve 2.4, the locking bushing 2.5, the connecting block 2.6, and the locking sleeve 2.6.
[0057] like Figure 11 As shown, the locking sleeve 2.4 is connected and fixed to the rear through-rib plate 2.2 by the locking sleeve end face locking bolt 2.4.1, and then fixed to the frame assembly 1.1 by the locking sleeve ring face tightening bolt 2.4.2.
[0058] Among them, there are 6 locking bolts on the end face of the locking sleeve 2.4.1 and a total of 6 locking bolts on the ring face of the locking sleeve 2.4.2. The appropriate number of bolts should be selected and installed according to whether the through pipe interferes with the installation.
[0059] like Figure 12 and Figure 13 As shown, the locking bushing 2.5 is connected and fixed to the front through-rib plate 2.1 by the locking bushing double-ear locking bolt 2.5.1, and then fixed to the frame assembly 1.1 by the locking bushing ring face tightening bolt 2.5.2.
[0060] Among them, there are 2 locking bolts for the double-ear locking bushing 2.5.1, and a total of 6 locking bushing annular tightening bolts 2.5.2.
[0061] In the segmented rib-passing plate 1.2, the front rib-passing plate 2.1 is generally welded with a circumferential combination of 3 to 4 types of head end component cage reinforcement specifications. Each combination has a different number of head end components 3.1, which are welded together on the front rib-passing plate 2.1.
[0062] The segmented reinforcing bar tray 1.2 typically has circumferential hole combinations compatible with 3 to 4 different cage reinforcement specifications on the rear reinforcing bar tray 2.2, such as the first compatible specification circumferential reinforcing bar hole group 2.2.1, the second compatible specification circumferential reinforcing bar hole group 2.2.2, and the third compatible specification circumferential reinforcing bar hole group 2.2.3. The complete segmented reinforcing bar tray 1.2 is formed by configuring and installing the middle section 3.2, the end of the guide tube 3.3, and the plunger 3.4 of the segmented reinforcing bar tube assembly 2.3 with the largest number of specifications on the outer ring.
[0063] When the automatic rebar threading machine starts threading, the worker selects, for example, the cage rebar specification of the first compatible specification circumferential threading hole group 2.2.1. The automatic threading machine, according to a preset program, automatically threades the gripped main rebar through the holes on the circumference of the first compatible specification circumferential threading hole group 2.2.1, thus completing the cage rebar threading and subsequent cage welding. When a change of specification is required, the worker rotates the middle section 3.2 and the end section 3.3 of the guide tube on the circumference of the first compatible specification circumferential threading hole group 2.2.1 on the rear threading plate 2.2 by an angle, pulling them out from the threading hole circular through hole 2.2.1.1 and the threading hole waist-shaped hole 2.2.1.2 respectively, and then threading them into the second compatible specification circumferential threading hole group 2.2.2 or the third compatible specification circumferential threading hole group 2.2.3, completing the change of specification. The worker then selects the corresponding program according to the changed specification and starts the automatic threading machine.
[0064] This device optimizes the overall structure of the threading disc and the threading tube assembly. The segmented threading tube assembly 2.3 divides the integral welded threading tube into three sections: the head end assembly 3.1, the middle section of the guide tube 3.2 (equipped with a plunger 3.4), and the end section of the guide tube 3.3. The head end assembly 3.1 is welded together with the front threading disc 2.1. Only the middle section of the guide tube 3.2 and the end section of the guide tube 3.3 are installed in the maximum required quantity. This newly designed threading tube assembly structure allows for quick installation and disassembly for compatible specification switching. When changing specifications, simply detach the assembly of the middle section of the guide tube 3.2 and the end section of the guide tube 3.3 and insert it into the hole on the corresponding specification of the rear threading disc 2.2. Rotate it at an angle, and the ball bearing on the plunger 3.4 provides pre-tightening force to lock the rear threading disc 2.2, preventing the guide tube from rotating and loosening. The limiting block on the middle section of the guide tube 3.2 prevents axial loosening of the guide tube, thus achieving quick assembly and disassembly for specification changing. By using the above methods, rapid changeover of compatible specifications within the same tooling tray can be achieved. No crane assistance is required during the changeover, and one worker can complete the tooling changeover. The changeover time is reduced by 2 / 3, improving the overall changeover efficiency and thus increasing production efficiency.
[0065] The entire rib-threading disc structure is simplified into two rib-threading discs, front and back, using two optical discs with rib-threading holes for installation as rib-threading pipes.
[0066] The front threading plate 2.1 is welded together with the head end component 3.1 in the segmented threading tube assembly to accommodate three prefabricated specifications and reduce the frequency of changeovers. Only when the roll welding exceeds these three specifications will it be necessary to replace the front part of the tooling. When producing within these three specifications, only the middle section and the end of the threading tube need to be replaced to achieve the changeover of the three specifications.
[0067] The segmented rebar plate 1.2 allows a single worker to change tooling without the need for a crane or other auxiliary tools, thus saving labor costs.
[0068] The innovative segmented rebar assembly enables rapid disassembly and installation between compatible rebar tray tooling specifications, facilitating quick changeover, saving changeover time, and improving production efficiency.
[0069] The segmented component structure of the through-tube allows for localized replacement of worn parts without the need for complete replacement, thus saving costs.
[0070] This device optimizes the reinforcing pipe into a three-section structure, integrating the front section of the reinforcing pipe with the front reinforcing disc. The middle and end sections are connected secondary, and a specially designed structure allows for quick installation and removal of the rear reinforcing disc. This segmented reinforcing pipe and disc design, compared to the previous integrated design, allows for independent operation by one person, enabling rapid changeover of the reinforcing pipe and disc without the need for an auxiliary crane. This improves changeover efficiency and allows for partial replacement of worn parts based on the pipe's wear condition, eliminating the need to replace the entire pipe and saving maintenance costs.
[0071] The rear reinforcing bar tray 2.2 of this device features an innovative installation opening structure, enabling easier and faster installation and disassembly of the reinforcing bar. The entire reinforcing bar installation requires no auxiliary crane and allows for quick changeover by a single worker. The innovatively designed segmented reinforcing bar assembly allows for rapid disassembly and installation between compatible reinforcing bar trays of the same specifications, achieving rapid changeover functionality, saving changeover time, and improving production efficiency. The segmented assembly structure allows for localized replacement of worn parts without requiring complete replacement, saving costs. Furthermore, the front section of the reinforcing bar structure has undergone special design treatment to ensure compatibility with the main reinforcing bar area. In this case, after the reinforcement is threaded through, the accuracy deviation of the main reinforcement spacing is smaller, and the quality control of the cage reinforcement is better.
[0072] This invention utilizes a segmented rebar threading device and rebar threading disc. By optimizing the rebar threading disc structure and the rebar threading component structure, the overall tooling weight is reduced to approximately half of the previous weight. This enables rapid disassembly and installation of the rebar threading component, facilitating quick model changeovers. No crane assistance is required during model changeovers; a single worker can complete the tooling replacement, reducing changeover time by two-thirds and improving overall changeover efficiency, thereby increasing production efficiency.
[0073] In this specification, the present invention has been described with reference to specific embodiments thereof. However, it will be apparent that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, the specification and drawings should be considered illustrative rather than restrictive.
