Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0025] like Figure 1 ,2 As shown, a punch press servo automatic feeding system includes a feeding bracket 1, a punch press 2, and a discharge bracket 3 arranged sequentially. The top of the feeding bracket 1 is provided with a first guide rail 11 and a rack 12 along its length. The first guide rail 11 has two rails, and the rack 12 is arranged parallel to the first guide rail 11. A horizontal crossbeam 13 slides on the first guide rail 11. The crossbeam 13 is perpendicular to the axis of the feeding bracket 1. A motor 131 that meshes with the rack 12 is fixedly connected to the crossbeam 13. The motor 131 can drive the crossbeam 13 to move horizontally along the first guide rail 11 on the feeding bracket 1.

[0026] A horizontal second guide rail 132 is provided on the side of the crossbeam 13 near the punch press 2. Two second guide rails 132 are provided. A horizontal first lead screw 133 is rotatably connected to the crossbeam 13. The first lead screw 133 is parallel to the second guide rail 132. One end of the first lead screw 133 is fixedly connected to a first handwheel 1331. A slide plate 14 is slidably mounted on the second guide rail 132. A first lead screw nut 1332, which is fixedly connected to the slide plate 14, is screwed onto the first lead screw 133. A slide block 141 is fixedly connected to the outside of the slide plate 14. A lifting plate 15, which can be raised and lowered, is slidably mounted on the slide block 141. A vertical... A straight second lead screw 151 is fixed to the side of the slide plate 14 near the lifting plate 15, and a second lead screw nut 142 is screwed to the second lead screw 151. A clearance groove 152 is opened on the lifting plate 15 to allow the second lead screw nut 142 to pass through. A second handwheel 1511 is fixed to the top of the second lead screw 151. A push rod 153 perpendicular to the lower part of the lifting plate 15 is fixed to it. The front end of the push rod 153 is provided with a C-shaped material bin 1521 with its opening facing forward. A clamping cylinder 1522 is fixed to the top of the C-shaped material bin 1521. The cylinder rod of the clamping cylinder 1522 extends into the C-shaped material bin 1521.

[0027] Manually rotating the first handwheel 1331 causes the first screw nut 1332 on the first screw 133 to drive the slide plate 14 to slide horizontally along the second guide rail 132, allowing the slide plate 14 to move closer to or further away from the feeding bracket 1. Manually rotating the second handwheel 1511 causes the second screw nut 142 on the slide plate 14 to rotate, driving the lifting plate 15 to move vertically relative to the slide plate 14, ultimately achieving vertical displacement of the push rod 153 relative to the feeding bracket 1.

[0028] like Figure 3 As shown, the feeding bracket 1 is provided with a material holding assembly 4 on the side near the push rod 153. The material holding assembly 4 includes multiple components and is spaced apart along the length direction of the feeding bracket 1.

[0029] The feeding bracket 1 is equipped with a material pressing device 5 at one end near the punch press 2, and the material pressing device 5 corresponds to the material holding assembly 4 below it.

[0030] like Figure 3 , 4As shown, the material holding assembly 4 includes a material holding assembly 41 and a clamping assembly 42. The material holding assembly 41 includes a vertical material holding slide rail 411 fixedly connected to the feeding bracket 1. A material holding frame 412 is slidably mounted on the material holding slide rail 411. A lifting cylinder 413 that drives the material holding frame 412 to slide up and down is fixedly connected to the feeding bracket 1 below the material holding frame 412. The clamping assembly 42 is provided on the top of the material holding frame 412.

[0031] The lifting cylinder 413 can drive the material support frame 412 on the material support slide rail 411 to move up and down, thereby lifting the material to be stamped on the material support frame 412.

[0032] The clamping assembly 42 includes a horizontal support 421 fixed to the top of the material support frame 412. The support 421 is rod-shaped and perpendicular to the axis of the feeding bracket 1. A clamping slide rail 422 is fixed above the support 421 along the length direction. A clamping slider 423 is slidably mounted on the clamping slide rail 422. A vertical first clamping roller 4231 is provided on the clamping slider 423. A clamping cylinder 4211 that drives the clamping slider 423 to slide is fixed to one end of the support 421. A vertical second clamping roller 4212 is provided on the side of the support 421 away from the clamping cylinder 4211. The first clamping roller 4231 and the second clamping roller 4212 are arranged opposite to each other.

[0033] The clamping cylinder 4211 can drive the clamping slider 423 on the clamping slide rail 422 to synchronously drive the first clamping roller 4231 to move closer to or away from the second clamping roller 4212. When the first clamping roller 4231 moves closer to the second clamping roller 4212, the first clamping roller 4231 and the second clamping roller 4212 can clamp the material to be stamped.

[0034] The clamping of the material by the first clamping roller 4231 and the second clamping roller 4212 can ensure the straightness of the material's movement during the feeding process and ensure the stamping accuracy. Since the first clamping roller 4231 and the second clamping roller 4212 roll synchronously with the material during the clamping process, the resistance of the material during the feeding process can be reduced.

[0035] like Figure 6 As shown, a horizontal material support roller 6 is provided on the support 421. The two ends of the material support roller 6 are rotatably connected to the support plate 61. The bottom of the support plate 61 is provided with an elongated mounting groove 611 extending vertically. The support plate 61 is connected to the support 421 by bolts passing through the mounting groove 611.

[0036] The support plate 61 is provided with a long strip-shaped mounting groove 611, which can adjust the height of the material support roller 6 relative to the support 421 to meet the needs of supporting materials of different shapes. When the material moves along the axial direction of the feeding bracket 1, the material support roller 6 can also roll synchronously with the material to reduce the resistance of the material movement.

[0037] like Figure 3 ,5 As shown, the material pressing device 5 includes a mounting plate 51 on the first guide rail 11, a slide rail seat 511 fixedly connected above the mounting plate 51, a support plate 52 horizontally slidably mounted on the slide rail seat 511, the sliding direction of the support plate 52 being perpendicular to the axis of the feeding bracket 1, a vertical linear pusher 521 fixedly connected to the side of the support plate 52 near the material holding assembly 4, the push rod of the linear pusher 521 being connected to a rotatable pressure roller 5211, the axis of the pressure roller 5211 being parallel to the axis of the material holding roller 6 and located in the same vertical plane, a positioning cylinder 522 fixedly connected to the other side of the support plate 52, the cylinder rod of the positioning cylinder 522 being connected to the vertical plate 512 fixedly connected to the mounting plate 51.

[0038] like Figure 5 As shown, in one embodiment, in order to facilitate the adjustment of the relative position between the pressure roller 5211 and the material support roller 6, an adjustment slider 513 is fixedly connected to the bottom of the mounting plate 51 and slidably mounted on the first guide rail 11. A limiting screw is screwed onto the mounting plate 51, and the limiting screw abuts against the feeding bracket 1.

[0039] To ensure that the pressure roller 5211 corresponds vertically to the material support roller 6 on the material support clamping assembly 4 below it, the mounting plate 51, which is slidably mounted on the first guide rail 11, is moved so that both the pressure roller 5211 and the material support roller 6 are located in the plane perpendicular to the axis of the feeding bracket 1. Then, the limiting screw on the mounting plate 51 is tightened to limit the mounting plate 51. The positioning cylinder 522 is activated, which drives the support plate 52 to slide on the slide rail seat 511 and moves the pressure roller 5211 directly below the material support roller 6. Finally, the linear actuator 521 is activated, driving the pressure roller 5211 to move downward and press against the material on the material support roller 6. The material pressing device 5 improves the stability of material feeding in the horizontal direction and ensures the accuracy of material stamping.

[0040] The top of the discharge bracket 3 is provided with several discharge rollers 31 spaced apart along the length direction, and the discharge rollers 31 are rotatably connected to the discharge bracket 3. The material after being punched by the punch press is fed onto the discharge rollers 31 of the discharge bracket 3, which can conveniently send the material to the next process.

[0041] The worktable of the punch press 2 is provided with a guide mold 21 for material passage, the guide mold 21 is provided with a guide groove 211 for material passage, and the center of the guide mold 21 is provided with a clearance hole 212 for the punch of the punch press 2 to pass through.

[0042] The system operates as follows: First, the motor 131 is started, moving the crossbeam 13 to the outside of the long rod-shaped material, and feeding the front end of the material into the guide groove 211 of the guide mold 21. The lifting cylinder 413 is controlled to lift and lower, and the material support roller 6 is brought into contact with the bottom of the material to ensure that the material support roller 6 lifts the material horizontally. Then, the clamping cylinder 4211 is started, bringing the first clamping roller 4231 closer to the second clamping roller 4212, so that the first clamping roller 4231 can clamp the material. The first handwheel 1331 is manually rotated to move the slide plate 14 horizontally on the second guide rail 132, and the push rod 153 on the lifting plate 15 is positioned above the material. The second handwheel 1511 is manually rotated to move the lifting plate 15 up and down relative to the slide plate 14, and the push rod 153... Coaxial with the long rod-shaped material; the control motor 131 drives the crossbeam 13 to move closer to the material, and after the C-shaped material bin 1521 on the push rod 153 is inserted into the tail end of the long rod-shaped material, the clamping cylinder 1522 is activated to clamp the tail end of the material; the mounting plate 51 on the first guide rail 11 is manually slid so that the pressure roller 5211 and the material support roller 6 are both located in the plane of the vertical feeding bracket 1 axis, and then the limit screw on the mounting plate 51 is tightened to limit and fix the mounting plate 51. The positioning cylinder 522 is activated to make the support plate 52 slide on the slide rail seat 511 and move the pressure roller 5211 to directly below the material support roller 6. The linear propeller 521 is activated to drive the pressure roller 5211 to press down on the material on the material support roller 6 to achieve pressure on the material, ensure the stability of the material during the feeding process, and improve the stamping accuracy.

[0043] The guide mold 21 is equipped with a probe to determine the initial position of the long rod-shaped material, achieving initial positioning of the material. The motor 131 can be driven and controlled by existing CNC technology. Simultaneously, by controlling the speed and time of the motor 131, the pushing speed and length of the material by the push rod 153 are controlled. The punch press 2 then performs corresponding punching. After the material is punched, the clamping cylinder 1522 releases its grip on the material. The punching of the next material follows the same operation. The subsequent material can push the previous material out of the guide mold 21 and send it to the discharge bracket 3 for the next process. This system can precisely control the feeding length of the material and achieve punching, featuring fast feeding speed and precise length control.

[0044] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
