[0057] Refer to Figures 1 to 4, which is the first embodiment of the present utility model, proposes a throat hoop strip stamping machine for punching and cutting a steel strip, including a stamping machine main body 1; for feeding the steel strip, the feeding device 2 includes: a first mounting frame 201 disposed at the feeding end of the stamping machine main body 1; both ends of the first driving roller 202 are rotatably disposed on the first mounting frame 201, located at one end of the first mounting frame 201 close to the stamping machine main body 1, and the first driving roller 202 abuts against the lower surface of the steel strip; there are two sliding seats 203 and they are oppositely arranged, and both sliding seats 203 are vertically slidably disposed on the first mounting frame 201; both ends of the second driving roller 204 are rotatably disposed on the two sliding seats 203, the second driving roller 204 is located directly above the first driving roller 202, and after the sliding seat 203 slides, the second driving roller 204 approaches or moves away from the first driving roller 202; both ends of the rotating shaft 205 are rotatably disposed on the two sliding seats 203; a cam 206 is disposed on the rotating shaft 205, and after the rotating shaft 205 rotates, the cam 206 abuts against the first mounting frame 201 to make the sliding seat 203 slide upward.

[0058] In this embodiment, in order to solve the problem that when the throat hoop strip stamping machine cuts, due to the continuous close contact between the feeding device and the upper and lower surfaces of the steel strip, stress is generated to deform the steel strip, a throat hoop strip stamping machine is designed, including a stamping machine main body 1 and a feeding device 2. Specifically, the first mounting frame 201 of the feeding device 2 is installed at the feeding end of the stamping machine main body 1; both ends of the first driving roller 202 are rotatably installed on one end of the first mounting frame 201 close to the stamping machine main body 1 through bearings, and it is in close contact with the lower surface of the steel strip; two oppositely arranged sliding seats 203 can slide vertically on the first mounting frame 201; both ends of the second driving roller 204 are rotatably installed on the two sliding seats 203 and are located directly above the first driving roller 202; both ends of the rotating shaft 205 are also rotatably installed on the two sliding seats 203, and a cam 206 is disposed on the rotating shaft 205; when the rotating shaft 205 rotates, the cam 206 rotates accordingly; when the cam 206 abuts against the first mounting frame 201, an upward thrust will be generated to make the sliding seat 203 slide upward, thereby driving the second driving roller 204 away from the first driving roller 202, so that the feeding device 2 will not clamp the steel strip when the throat hoop strip stamping machine cuts, and the problem of stress generation causing the steel strip to deform is solved.

[0059] Furthermore, the feeding device 2 further includes: one end of a linkage rod 207 is disposed on the rotating shaft 205; one end of an abutting rod 208 is disposed at the output end of the stamping machine main body 1; a first abutting wheel 209 is disposed at the other end of the linkage rod 207. After the output end of the stamping machine main body 1 drops, the other end of the abutting rod 208 abuts against the first abutting wheel 209 to push the rotating shaft 205 to rotate.

[0060] In this embodiment, one end of the linkage rod 207 is mounted on the rotating shaft 205; one end of the abutting rod 208 is fixed to the output end of the stamping machine main body 1; the first abutting wheel 209 is disposed at the other end of the linkage rod 207; when the output end of the stamping machine main body 1 drops, the other end of the abutting rod 208 abuts against the first abutting wheel 209; the thrust generated by this abutment will push the linkage rod 207, thereby driving the rotation of the rotating shaft 205; the rotation of the rotating shaft 205 causes the cam 206 to abut against the first mounting bracket 201, thereby changing the position of the sliding seat 203.

[0061] The advantage is that the automatic pushing of the rotating shaft 205 is realized through the action of the output end of the stamping machine main body 1, without the need for an additional power source or manual operation, realizing the automatic adjustment of the feeding device 2; the feeding device 2 cooperates with the output action of the stamping machine main body 1, ensuring the synchronization of the adjustment of the feeding device 2 and the stamping process, and improving the coordination and efficiency of production.

[0062] Furthermore, the feeding device 2 further includes a first pressing plate 210. Both ends of the first pressing plate 210 are disposed on the first mounting bracket 201. The cam 206 abuts against the first mounting bracket 201 through the first pressing plate 210. The upper surface of the first pressing plate 210 is at the same horizontal plane as the top of the first driving roller 202. The upper surface of the first pressing plate 210 abuts against the lower surface of the steel strip; both ends of the second pressing plate 211 are disposed on the first mounting bracket 201, and the second pressing plate 211 is disposed directly above the first pressing plate 210.

[0063] In this embodiment, both ends of the first pressing plate 210 are stably disposed on the first mounting bracket 201; since the cam 206 abuts against the first mounting bracket 201 through the first pressing plate 210, when the cam 206 rotates, it will abut against the first pressing plate 210, thereby generating an upward thrust, causing the sliding seat 203 to slide upward, thereby driving the second driving roller 204 away from the first driving roller 202; the upper surface of the first pressing plate 210 is at the same horizontal plane as the top of the first driving roller 202. When the steel strip is conveyed, its lower surface closely abuts against the upper surface of the first pressing plate 210; both ends of the second pressing plate 211 are also fixed on the first mounting bracket 201 and are located directly above the first pressing plate 210; the cooperation of the first pressing plate 210 and the second pressing plate 211 can better restrict the movement of the steel strip in the vertical direction, making the conveying of the steel strip more stable and reliable, reducing the conveying deviation caused by the jumping of the steel strip; the stable conveying helps the steel strip to accurately enter the stamping machine main body 1 for punching and cutting operations, thereby improving the feeding accuracy and the quality of subsequent processing.

[0064] Furthermore, the feeding device 2 further includes a supporting roller 212. Both ends of the supporting roller 212 are rotatably disposed on the first mounting bracket 201, located at the other end of the first mounting bracket 201. The top of the supporting roller 212 is at the same horizontal plane as the top of the first driving roller 202.

[0065] In this embodiment, both ends of the idler 212 are installed at the other end of the first mounting frame 201 through corresponding rotating components; its top is at the same horizontal plane as the top of the first driving roller 202; when the steel strip is conveyed from a distance, it first contacts the idler 212; the idler 212 rotates as the steel strip moves, providing support and guidance for the steel strip.

[0066] The advantage is that the idler 212 and the first driving roller 202 are at the same horizontal plane, providing continuous and stable support for the steel strip, preventing the steel strip from sagging or bending due to lack of support during transportation; it helps to maintain the flatness of the steel strip in the transportation path, reduce resistance and jamming, and enable the steel strip to move smoothly to the subsequent processing position.

[0067] Furthermore, the feeding device 2 further includes straightening members 213. The number of straightening members 213 is several. The straightening member 213 includes a first straightening roller 2131. Both ends of the first straightening roller 2131 are rotatably arranged on the first mounting frame 201, located between the first driving roller 202 and the idler 212. The top of the first straightening roller 2131 is at the same horizontal plane as the top of the first driving roller 202 and abuts against the lower surface of the steel strip; both ends of the second straightening roller 2132 are rotatably and slidably arranged on the first mounting frame 201, located directly above the first straightening roller 2131. After the second straightening roller 2132 slides, the second straightening roller 2132 abuts against the upper surface of the steel strip.

[0068] In this embodiment, multiple straightening members 213 are distributed on the first mounting frame 201; both ends of the first straightening roller 2131 are installed on the first mounting frame 201 through rotating components such as bearings, located between the first driving roller 202 and the idler 212. Its top is at the same horizontal plane as the top of the first driving roller 202 and tightly abuts against the lower surface of the steel strip; both ends of the second straightening roller 2132 can rotate on the first mounting frame 201 and can also be adjusted slidably; it is located directly above the first straightening roller 2131; when the steel strip passes by, according to the actual situation of the steel strip, the position of the second straightening roller 2132 is slidably adjusted so that it abuts against the upper surface of the steel strip; in this way, the first straightening roller 2131 and the second straightening roller 2132 apply pressure to the steel strip from the upper and lower directions, playing a role in straightening the steel strip, eliminating possible bending and twisting of the steel strip, and enabling it to enter the subsequent processing process in a flat state; the advantage is that the steel strip is straightened by the straightening members 213, ensuring that the steel strip entering the stamping and cutting processes has good flatness, and improving the final product quality of the hose clamp strip.

[0069] Further, the feeding device 2 further includes: a rectifying member 214, the rectifying member 214 includes a slide rail 2141, and both ends of the slide rail 2141 are arranged on the first mounting bracket 201; there are two guide posts 2142, and one ends of the two guide posts 2142 are slidably arranged on the slide rail 2141 respectively and are abutted against both sides of the steel strip.

[0070] In this embodiment, both ends of the slide rail 2141 are stably mounted on the first mounting bracket 201; one ends of the two guide posts 2142 are respectively slidably arranged on the slide rail 2141; when the steel strip passes through the rectifying member 214 during feeding, the two guide posts 2142 are respectively abutted against both sides of the steel strip; if the steel strip has a lateral offset during transmission, the guide posts 2142 will slide correspondingly on the slide rail 2141 to guide and rectify the steel strip in real time, ensuring that the steel strip can be conveyed along the correct path and accurately enter the subsequent processing procedures.

[0071] Further, the feeding device 2 further includes a first mounting plate 215, both ends of the first mounting plate 215 are arranged on the first mounting bracket 201 and are located between the idler roller 212 and the straightening member 213; a first sensing member 216 is arranged on the first mounting plate 215, and the sensing end of the first sensing member 216 is in the same plane as the top of the first driving roller 202.

[0073] The advantage is that through the setting that the first sensing member 216 and the top of the first driving roller 202 are in the same plane, the position and passing condition of the steel strip can be accurately detected, providing an accurate signal for the control of the feeding process.

[0074] Further, the feeding device 2 further includes a second mounting plate 217, both ends of the second mounting plate 217 are arranged on the first mounting bracket 201 and are located between the first driving roller 202 and the stamping machine main body 1; a second sensing member 218 is arranged on the second mounting plate 217, and the sensing end of the second sensing member 218 is in the same plane as the top of the first driving roller 202.

[0076] The advantage is that an additional layer of protection is added. Only when both the first sensing member 216 and the second sensing member 218 sense that a steel strip has passed through, will the press main body 1 start, greatly increasing the safety of the equipment.

[0077] Furthermore, it further includes a nozzle 4. The nozzle 4 is arranged on the press main body 1 and is located between the stamping die 3 and the feeding device 2.
