Description

Technical Field

[0001] The utility model relates to the technical field of cold heading machines, in particular to a cross-cutting structure of a cold heading machine. Background Art

[0002] Cold heading machine is a stamping machine in mechanical manufacturing, which forms the material into the required shape without making any changes to the raw material.

[0003] In the prior art, the utility model with the authorization announcement number CN217474771U is named: A cross-cutting structure of a cold heading machine, which is used in conjunction with a fixed sleeve, a first mounting seat, a second mounting seat, a third mounting seat, a fourth mounting seat, a first driving rod, and a second driving rod. During operation, the wire is pushed to the cutting die by the feed ejector, and then the fixed sleeve moves forward, so that the second driving rod drives the sliding sleeve to slide outward. While the sliding sleeve slides outward, the moving block is driven downward by the first driving rod, so that in the process of the moving block moving downward, the cutter moves downward to cut the wire. This method is simple to operate and is convenient for the cutter to cut the wire from top to bottom, and the wire residue falls directly into the collection frame.

[0004] However, it was found during use that the crosscutting knife in the above device was installed on the surface of the moving block, and it was unclear how to replace it. When the crosscutting knife was damaged, it could not be easily replaced.

[0005] In the prior art, the utility model with authorization announcement number CN207127155U is named: A cross-cutting structure of a cold heading machine, which cuts wire from top to bottom through the coordinated movement of the inclined punch needle and the feed punch needle, and has a simple structure and is easy to maintain.

[0006] However, during the use of the device, it is still unclear how to achieve convenient replacement of the cross-cutting knife, and the installation and maintenance of the cross-cutting knife are relatively troublesome. Utility Model Content

[0007] The utility model proposes a cross-cutting structure of a cold heading machine, which solves the problem of inconvenient replacement of the cross-cutting knife in the related art.

[0008] The technical solution of the utility model is as follows: a cross-cutting structure of a cold heading machine, comprising a fixed template, a reserved cavity being opened on the upper surface of the fixed template, a cylinder being installed inside the reserved cavity, a cross-cutting mechanism being provided at the output end of the cylinder, and the cross-cutting mechanism comprising a mounting block fixedly connected to the output end of the cylinder.

[0009] A cavity is provided inside the mounting block, and a bidirectional threaded rod is rotatably provided on the inner wall of the cavity. The outer surface of the bidirectional threaded rod is threadedly connected to two sliders that are slidably connected to the inner wall of the cavity. The ends of the two sliders that are away from each other are fixedly connected to a limiting rod. Two guide grooves are provided on the outer surface of the mounting block, and a cross-cutting knife is provided above the fixed template. The outer surface of the cross-cutting knife is fixedly connected to two guide blocks, and the outer surface of each guide block is provided with a limiting groove.

[0010] Furthermore, a cutting die is installed inside the fixed template, and the cross-cutting knife is located on one side of the cutting die. By setting the cutting die, the work of horizontal cutting of the wire can be facilitated.

[0011] Furthermore, the cutting die is provided with a feed ejector relative to the cutting die, and a ejector sleeve is installed at one end of the feed ejector. The outer surface of the ejector sleeve is fixedly connected to the feed template. By arranging the feed template, the ejector sleeve and the feed ejector to cooperate with each other, the wire conveying work can be facilitated.

[0012] Furthermore, the inner walls of the two guide grooves are provided with through holes corresponding to the limit rods, and the limit rods extend to the interior of the guide grooves through the through holes. By setting the through holes, the limit rods can be conveniently moved into the guide grooves, and the subsequent moving of the limit rods into the limit grooves is convenient, thereby facilitating the limiting work of the cross-cutting knife.

[0013] Furthermore, two guide columns are fixedly connected to the inner wall of the mounting block, and the two sides of the two sliders are respectively slidably sleeved on the outer surfaces of the two guide columns. By setting the guide columns, the two sliders can be more stable during the movement, which facilitates the adjustment of the positions of the two limit rods, and is beneficial to the disassembly and assembly of the cross-cutting knife.

[0014] Furthermore, the shaft end of the bidirectional threaded rod passes through the cavity and extends to the outside of the mounting block. The shaft end of the bidirectional threaded rod is fixedly connected to a handle. By setting the handle, the contact area of ​​the shaft end of the bidirectional threaded rod can be increased, making it easier to rotate the bidirectional threaded rod.

[0015] Furthermore, the size of the guide groove is consistent with the size of the guide block, and the diameter value of the limit groove is consistent with the diameter value of the limit rod. By limiting the above dimensions, the cross-cutting knife can be installed on the mounting block more stably.

[0016] Furthermore, the outer surfaces of the fixed template and the feed template are provided with mounting holes. By providing the mounting holes, the fixed template and the feed template can be conveniently installed in appropriate positions, which is beneficial to the cross-cutting work of the wire.

[0017] The working principle and beneficial effects of the utility model are as follows:

[0018] 1. The cross-cutting mechanism is provided in the present invention, so that the cross-cutting knife can be easily disassembled and assembled. The two guide blocks at one end of the cross-cutting knife are respectively inserted into the two guide grooves, and then the bidirectional threaded rod is rotated to drive the two sliders to move away from each other, so that the two limit rods extend through the two through holes to the inside of the two guide grooves and are inserted into the two limit grooves, thereby completing the limit installation of the cross-cutting knife. When the cross-cutting knife needs to be disassembled and maintained, it is only necessary to reverse the handle to move the two limit rods out of the corresponding limit grooves respectively, so that the limit of the cross-cutting knife can be released and the disassembly work is completed, which solves the problem of inconvenient replacement of the cross-cutting knife raised in the background technology.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1 to 6 As shown, this embodiment proposes a cross-cutting structure of a cold heading machine, including a fixed template 1, a reserved cavity 2 is opened on the upper surface of the fixed template 1, a cylinder 3 is installed inside the reserved cavity 2, and a cross-cutting mechanism 4 is provided at the output end of the cylinder 3. The cross-cutting mechanism 4 includes a mounting block 401 fixedly connected to the output end of the cylinder 3.

[0030] When the cylinder 3 is started, the mounting block 401 can be moved horizontally, which facilitates the subsequent horizontal cutting of the wire.

[0031] The mounting block 401 defines a cavity 402 therein. A bidirectional threaded rod 403 is rotatably sleeved on the inner wall of the cavity 402 . The outer surface of the bidirectional threaded rod 403 is threadedly connected to two sliders 404 that are slidably connected to the inner wall of the cavity 402 .

[0032] When the bidirectional threaded rod 403 rotates, the two sliders 404 can move toward or away from each other in the inner wall of the cavity 402 .

[0033] The ends of the two sliders 404 that are away from each other are fixedly connected to the limit rods 406. When the two sliders 404 move, they can drive the two limit rods 406 to move synchronously, making it convenient to limit other components through the two limit rods 406 in the future.

[0034] Two guide grooves 405 are formed on the outer surface of the mounting block 401 , a cross-cutting knife 409 is provided above the fixed template 1 , and the outer surface of the cross-cutting knife 409 is fixedly connected to two guide blocks 410 , and a limiting groove 411 is formed on the outer surface of each guide block 410 .

[0035] The inner walls of the two guide grooves 405 are provided with through holes corresponding to the limit rods 406, and the limit rods 406 extend to the interior of the guide grooves 405 through the through holes. By setting the through holes, the limit rods 406 can be conveniently moved into the guide grooves 405, and the limit rods 406 can be conveniently moved into the limit grooves 411 later, thereby facilitating the limiting work of the cross-cutting knife 409.

[0036] Two guide columns 407 are fixedly connected to the inner wall of the mounting block 401, and the two sides of the two sliders 404 are slidably mounted on the outer surfaces of the two guide columns 407. By setting the guide columns 407, the two sliders 404 can be more stable during the movement, which facilitates the adjustment of the positions of the two limit rods 406 and is beneficial to the disassembly and assembly of the cross-cutting knife 409.

[0037] The rotating shaft end of the bidirectional threaded rod 403 passes through the cavity 402 and extends to the outside of the mounting block 401. The rotating shaft end of the bidirectional threaded rod 403 is fixedly connected to a handle 408. By setting the handle 408, the contact area of ​​the rotating shaft end of the bidirectional threaded rod 403 can be increased, making it easier to rotate the bidirectional threaded rod 403.

[0038] The size of the guide groove 405 is consistent with the size of the guide block 410, and the diameter value of the limiting groove 411 is consistent with the diameter value of the limiting rod 406. By limiting the above dimensions, the cross-cutting knife 409 can be installed more stably on the mounting block 401.

[0039] When installing the cross-cutting knife 409, the two guide blocks 410 can be inserted into the two guide grooves 405 respectively, and then the handle 408 is rotated to rotate the bidirectional threaded rod 403, thereby driving the two sliders 404 and the limit rod 406 to move away from each other, so that the two limit rods 406 can be inserted into the two limit grooves 411 respectively, thereby realizing the limitation of the two guide blocks 410, which means that the limitation installation of the cross-cutting knife 409 is completed.

[0040] For subsequent maintenance work on the cross-cutter 409, the handle 408 can be rotated in the opposite direction to move the two limit rods 406 out of the corresponding limit slots 411, thereby releasing the limit on the guide block 410, and the cross-cutter 409 can be directly pulled out from the two guide slots 405 to complete the quick disassembly work, which facilitates the subsequent maintenance or replacement of the cross-cutter 409 and saves time and effort.

[0041] Example 2

[0042] like Figures 1 to 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a cutting die 5 is installed inside the fixed template 1, and the cross-cutting knife 409 is located on one side of the cutting die 5. By setting the cutting die 5, the work of horizontal cutting of the wire can be facilitated.

[0043] A feed ejector 8 is provided opposite to the cutting die 5, and a ejector sleeve 7 is installed at one end of the feed ejector 8. The outer surface of the ejector sleeve 7 is fixedly connected to the feed template 6. By arranging the feed template 6, the ejector sleeve 7 and the feed ejector 8 to cooperate with each other, the wire transportation work can be facilitated.

[0044] In this way, by driving the air cylinder 3 to work, the cross-cutting knife 409 can be moved horizontally, thereby being able to perform a cross-cutting operation on the wire rod in the ejector sleeve 7 and the cutting die 5 .

[0045] The outer surfaces of the fixed template 1 and the feeding template 6 are both provided with mounting holes. By providing the mounting holes, the fixed template 1 and the feeding template 6 can be conveniently installed in appropriate positions, which is beneficial to the cross-cutting work of the wire.

[0046] Working principle: By setting the cutting die 5, feeding template 6, ejector sleeve 7 and feeding ejector 8 to cooperate with each other, the wire can be pushed into the cutting die 5 through the feeding ejector 8, and then the cylinder 3 is controlled to work, driving the cross-cutting knife 409 to move laterally in the direction of the wire, so that the cross-cutting knife 409 can cut the wire laterally. After using it for a period of time, the cross-cutting knife 409 needs to be maintained or replaced. At this time, the cross-cutting knife 409 can be removed by rotating the handle 408 counterclockwise. When the handle 408 rotates counterclockwise, it can drive the bidirectional threaded rod 403 to rotate counterclockwise, so that the two sliders 404 can move closer to each other, so that the two limit rods 406 can be moved out of the corresponding limit grooves 411 respectively, releasing the limit on the guide block 410, so that the cross-cutting knife 409 can be directly removed from The two guide grooves 405 can be disassembled for maintenance or replacement, and then for the installation of the cross-cutter 409, the two guide blocks 410 at one end of the cross-cutter 409 can be inserted into the corresponding guide grooves 405 respectively, and then the handle 408 is rotated clockwise to make the bidirectional threaded rod 403 rotate clockwise, so that the two sliders 404 can move away from each other, and the two limit rods 406 can also move away from each other. The two limit rods 406 will move to the inside of the corresponding guide grooves 405 through the through holes inside the two guide grooves 405, and then be inserted into the corresponding limit grooves 411, realizing the limiting work of the guide blocks 410, which means that the limiting installation work of the cross-cutter 409 is completed, which can facilitate the regular maintenance or replacement of the cross-cutter 409, thereby improving the practicality of the device.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
