A handle 414 drives a baffle 411 to move left and right. The baffle 411, in conjunction with a mounting block 401, allows for quick disassembly and installation of the cutting blade 404, thus enabling rapid replacement of the cutting blade 404. By setting up the tool changing structure 4, the problem of time-consuming and labor-intensive tool replacement, which is usually fixed to the drive equipment by bolts, is solved in existing spiral cylindrical compression spring forming devices. The operation method is simple, the replacement efficiency is improved, and the downtime for tool replacement is reduced, thereby improving production efficiency.

[0029] The tool changing structure 4 includes a mounting block 401, on which a placement groove 402 is provided, and a locking post 403 is installed in the inner cavity of the placement groove 402 and located on the upper and lower sides.

[0030] The mounting block 401 is slidably connected to the cutting blade 404 via the locking post 403;

[0031] A fixing cylinder 405 is installed on the side wall of the mounting block 401, and a spring 406 is installed in the inner cavity of the fixing cylinder 405.

[0032] A first groove 407 is provided on the mounting block 401 and corresponding to the spring 406. The mounting block 401 is slidably connected to the pressure block 408 through the first groove 407.

[0033] The mounting block 401 has a first limiting groove 409, and the mounting block 401 is slidably connected to the slider 410 through the first limiting groove 409. A baffle 411 is installed at the bottom of the slider 410.

[0034] Mounting block 401 is mounted on the side wall and correspondingly mounted on the left and right sides with limit blocks 412.

[0035] In this embodiment, reference is made to Figure 1-3 As shown, the end face of the mounting block 401 is connected to the drive end of the hydraulic cylinder 3, and the connection between the mounting block 401 and the hydraulic cylinder 3 is a sliding connection; the side wall of the pressure block 408 is fixedly connected to the side wall of the baffle 411, and a second sliding groove 413 is provided on the baffle 411 and corresponding to the limiting block 412, and the baffle 411 is slidably connected to the limiting block 412 through the second sliding groove 413; a handle 414 is installed on the side wall of the baffle 411, and a through hole 415 is provided on the cutting blade 404 and corresponding to the locking post 403;

[0036] A handle 414 is installed on the side wall of the baffle 411, making it more convenient to pull the baffle 411.

[0037] In this embodiment, reference is made to Figure 3As shown, the placement groove 402 and the cutting blade 404 are adapted to each other, and the slider 410 and the limiting block 412 have a T-shaped cross-section; a support plate 5 is installed on the end face of the worktable 1 and on the rear side of the mounting frame 2. The support plate 5 is bolted to a drive motor 6. The drive end of the drive motor 6 is provided with a connecting shaft 7, and the other end of the connecting shaft 7 is provided with a spindle 8. A stop block 9 is installed on the side wall of the mounting frame 2.

[0038] The placement groove 402 is adapted to the cutting blade 404, which makes the stability of the cutting blade 404 mounted on the mounting block 401 better.

[0039] Working principle: When using the spiral cylindrical compression spring forming device, the operator pulls the handle 414 to the left. The handle 414 drives the baffle 411 to move to the left, and at the same time, the baffle 411 drives the pressure block 408 to slide to the left. The pressure block 408 compresses the spring 406, causing the cutting blade 404 to completely separate from the baffle 411. The cutting blade 404 is then removed from the outside of the placement slot 402 and replaced with a new cutting blade 404. The limit block 412 is aligned with the locking post 403, and the new cutting blade 404 is placed into the placement slot 402. The operator then releases the handle 414. After the manual operation is stopped, the spring 406... Under the force of reset, spring 406 drives pressure block 408 to move to the right, and pressure block 408 drives baffle 411 to move to the right, so that pressure block 408 moves to the side wall of cutting blade 404, restricting the position of cutting blade 404 and realizing the quick replacement function of cutting blade 404. By setting the blade replacement structure 4, the problem of cutting blades of existing spiral cylindrical compression spring forming devices, which are usually fixed on the drive equipment with bolts, is solved. The operation method is simple, the replacement efficiency is improved, and the downtime of equipment for blade replacement is reduced, thereby improving production efficiency.

[0040] 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.
