Description

Technical Field

[0001] This utility model relates to the technical field of bolt processing equipment, specifically a bolt thread processing device. Background Technology

[0002] Pipe fixing bolts require thread rolling machines for processing during production. A thread rolling machine is a specialized piece of equipment used to process external threads on bolt blanks. Its core components are two opposing thread rolling plates with threaded teeth on their surfaces. One is a stationary plate, and the other is a moving plate. Driven by the machine tool, the moving plate moves linearly relative to the stationary plate, forcing the bolt blank placed between the two to form threads.

[0003] In existing technologies, thread rolling dies are typically single-piece structures with thread rolling grooves of specific specifications on one side. When different thread specifications need to be processed, or when the thread rolling grooves on one side are worn to the point of needing replacement, the entire thread rolling die must be removed from the machine tool, replaced with a new thread rolling die, and reinstalled. This process is time-consuming and reduces production efficiency. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a bolt thread processing device capable of quickly switching working tooth surfaces, thus solving the problems mentioned in the background art.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: a bolt threading device, comprising a machine tool and a first thread rolling plate and a second thread rolling plate arranged opposite to each other. The machine tool drives at least one thread rolling plate to move, so that the two thread rolling plates cooperate to perform thread rolling on the workpiece. At least one of the thread rolling plates is a flip-up double-sided thread rolling plate. The double-sided thread rolling plate includes an outer frame mounted on the machine tool and a thread rolling plate body with thread rolling grooves on both sides. The thread rolling plate body is flip-uply mounted on the outer frame and has a locking mechanism for fixing the thread rolling plate body in the working position.

[0006] Preferably, a rotating shaft is fixedly connected to the wire plate body, a slide rail is provided on the outer frame, a sliding block is slidably fitted on the slide rail, and both ends of the rotating shaft are rotatably connected to the sliding block.

[0007] Preferably, the locking mechanism includes a first fixing hole and a second fixing hole on the outer frame, a screw hole on the wire plate body, and a fixing screw. The first fixing hole and the second fixing hole correspond to a first working position and a second working position of the wire plate body, respectively. When the wire plate body is flipped to the first working position, the first fixing hole aligns with the screw hole; when the wire plate body is flipped to the second working position, the second fixing hole aligns with the screw hole. The fixing screw passes through the first fixing hole or the second fixing hole and is threaded into the screw hole.

[0008] Preferably, the outer frame is rectangular, and the length of the outer frame is greater than the length of the wire plate body.

[0009] Preferably, the slide rails are provided as two rails, and the two slide rails are symmetrically arranged on the upper and lower sides of the outer frame.

[0010] Preferably, the dimensions of the wire-rolling grooves on both sides of the wire plate body are different. Beneficial effects

[0011] This utility model provides a bolt thread processing device. It has the following beneficial effects: This bolt threading device features a reversible thread rolling plate with grooves on both sides. When changing thread specifications or when one groove wears out, there's no need to remove the entire thread rolling plate from the machine. Simply loosen the locking mechanism, flip the plate, and re-secure it. This greatly simplifies the operation, reduces equipment setup and downtime, and is particularly suitable for multi-variety, small-batch production, effectively improving efficiency.

[0012] This bolt threading device achieves smooth rotation and precise positioning of the thread plate body through the cooperation of a rotating shaft, slide rail, and sliding block. Two fixing holes on the outer frame ensure that the thread plate body can be reliably locked in any working position, guaranteeing stability during processing.

[0013] This bolt thread processing device integrates two specifications of thread rolling grooves onto a single plate body, reducing the material required for a single thread rolling plate base. At the same time, it reduces the frequency of replacing the entire thread rolling plate, lowers spare parts inventory and management costs, and improves overall production efficiency.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] This utility model provides a bolt thread processing device, such as... Figure 1-3 As shown, the device includes a machine tool and two opposing thread rolling plates. The machine tool is a conventional structure in the art, used to drive one of the thread rolling plates to perform linear motion, cooperating with the other thread rolling plate to perform thread rolling on bolt blanks. The core improvement of this utility model lies in the fact that at least one of the thread rolling plates adopts a flip-up double-sided thread rolling plate structure.

[0018] The double-sided thread rolling die mainly includes an outer frame 2 and a thread rolling die body 1. The outer frame 2 is fixedly installed on the machine tool in a conventional manner. The outer frame 2 is preferably a rectangular structure, and its length is greater than the length of the thread rolling die body 1, so as to provide sufficient installation and movement space for the internal mechanism.

[0019] The wire rolling plate body 1 is the core component for performing the wire rolling function. Wire rolling grooves are machined on both its front and back sides. Depending on different application requirements, the wire rolling grooves on both sides can be designed to the same specification to extend service life, or they can be designed to different specifications, such as M8 and M10, thus achieving "one plate for two purposes".

[0020] The wire rolling plate body 1 is installed inside the outer frame 2 via a flipping mechanism. Specifically, a rotating shaft 3 is fixedly connected to the wire rolling plate body 1. Two slide rails 5 are symmetrically arranged on the upper and lower sides of the outer frame 2, and a sliding block 4 is slidably engaged on each slide rail 5. The two ends of the rotating shaft 3 are rotatably connected to the two sliding blocks 4 through bearings. This structure allows the wire rolling plate body 1 to be flipped around the axis of the rotating shaft 3, and also to be finely adjusted along the slide rails 5 by the sliding blocks 4, so as to be precisely aligned with another wire rolling plate when installed on a machine tool.

[0021] To reliably fix the wire plate body 1 in the processing position, a locking mechanism is provided. This locking mechanism includes a first fixing hole 6 and a second fixing hole 7 on the outer frame 2, a screw hole 9 on the top of the wire plate body 1, and a fixing screw 8. The positions of the first fixing hole 6 and the second fixing hole 7 are precisely calculated to correspond to two working positions before and after the wire plate body 1 is rotated 180 degrees.

[0022] When side A of the wire plate body 1 is needed, flip it to the first working position. At this time, the screw hole 9 on the wire plate body 1 is coaxially aligned with the first fixing hole 6 on the outer frame 2. Tighten the fixing screw 8 by passing it through the first fixing hole 6 and screwing it into the screw hole 9 to securely lock the wire plate body 1.

[0023] When it is necessary to switch to side B of the wire plate body 1, simply loosen and remove the fixing screw 8, rotate the wire plate body 1 around the pivot 3, and adjust it to the second working position. At this time, the screw hole 9 will be coaxially aligned with the second fixing hole 7 on the outer frame 2. Use the same fixing screw 8 again to pass through the second fixing hole 7 and screw it into the screw hole 9 to tighten it, thus completing the switching of the working surface.

[0024] Working Principle: The double-sided thread rolling plate of this invention is installed as one of the thread rolling plates on a thread rolling machine. According to production requirements, the corresponding working surface of the thread rolling plate body 1 is selected and fixed using the aforementioned locking mechanism. The machine tool drives the thread rolling plate to process the workpiece. When it is necessary to change the thread specification or when the current working surface is worn, the flipping and fixing operation can be completed in just a few minutes without disassembling the entire thread rolling plate unit, significantly improving production efficiency and flexibility.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
