[0048] The following is a preferred embodiment of a high-speed punch feeder provided by the present application which can solve the above technical problems.

[0049] Please refer to Figures 1-5 and Figure 10The preferred embodiment of the present application provides a high-speed punch press feeder, which comprises a Y-direction feeder 11. The Y-direction feeder 11 comprises a bottom plate 111a, two support plates 111b, a lower pressing wheel 112a, a fixed rod 111c, two adjusting plates 111d, an elastic member 113 and a first motor 114. The two support plates 111b are arranged on the bottom plate 111a in a spaced manner. The lower pressing wheel 112a is rotatably arranged on the two support plates 111b through two first bearings at two ends of the lower pressing wheel 112a respectively. The fixed rod 111c is connected to the two support plates 111b at two ends of the fixed rod 111c respectively. The adjusting plate 111d has two ends, i.e., a first end 111d1 and a second end 111d2. The two first ends 111d1 are rotatably connected to the two ends of the fixed rod 111c respectively. An upper pressing wheel 112b is rotatably arranged on the two adjusting plates 111d through two second bearings at two ends of the upper pressing wheel 112b respectively, and the upper pressing wheel 112b is arranged above the lower pressing wheel 112a. The elastic member 113 is used to provide pressure to the two second ends 111d2, so that the upper pressing wheel 112b is pressed towards the lower pressing wheel 112a. The first motor 114 is fixed on the bottom plate 111a, and a rotating shaft of the first motor 114 is connected to the lower pressing wheel 112a through a coupling, so as to drive the lower pressing wheel 112a to rotate, thereby conveying the material in the longitudinal direction.

[0050] The high-speed punch press feeder of the present application places the material between the upper pressing wheel 112b and the lower pressing wheel 112a, and the lower pressing wheel 112a drives the upper pressing wheel 112b to rotate, thereby conveying the material. The two ends of the upper pressing wheel 112b are rotatably arranged on the two adjusting plates 111d, the two first ends 111d1 are rotatably connected to the two ends of the fixed rod 111c respectively, and the elastic member 113 is used to apply pressure to the two second ends 111d2, so that the upper pressing wheel 112b is pressed towards the lower pressing wheel 112a, thereby clamping the material, so that the feeding precision is high, the spacing between products can be set smaller when designing the punch arrangement, and the material is effectively saved.

[0051] Please refer to Figure 4 and Figure 6The Y-direction feeder 11 further comprises a top plate 115a, a pressing plate 115b and a screw rod 115c. Two ends of the top plate 115a are connected to top ends of the two support plates 111b respectively. Two ends of the pressing plate 115b are connected to the two second ends 111d2 respectively. The screw rod 115c comprises a threaded part 115c1 and a positioning part 115c2 along its axial direction, the threaded part 115c1 penetrates through the top plate 115a, the positioning part 115c2 is above the pressing plate 115b, and the diameter of the threaded part 115c1 is larger than that of the positioning part 115c2. The elastic member 113 is a compression spring, which is sleeved on the positioning part 115c2, two ends of the elastic member 113 abut against the threaded part 115c1 and the pressing plate 115b respectively, and the elastic member 113 is used for providing pressure to the pressing plate 115b. By rotating the threaded part 115c1, the compression degree of the elastic member 113 can be changed, so that the resilience of the elastic member 113 can be changed. According to the thickness of the material, the resilience of the elastic member 113 is adjusted to an appropriate size. Two ends of the pressing plate 115b are connected to the two second ends 111d2 respectively, so that the two adjusting plates 111d can rotate simultaneously, and the force acting on the upper pressing wheel 112b is balanced. The first end 111d1 rotates around the fixed rod 111c, the second end 111d2 is connected to the pressing plate 115b, and the connection between the upper pressing wheel 112b and the adjusting plate 111d is located between the first end 111d1 and the second end 111d2. When the adjusting plate 111d rotates, the moving distance of the upper pressing wheel 112 is smaller than that of the pressing plate 115b, so that the movement of the upper pressing wheel 112 can be amplified, and it is convenient to detect the abnormality at the pressing plate 115b. A pressure sensor can be arranged at the elastic member 113 to detect the change of pressure. In the embodiment, the screw rod 115c and the elastic member 113 are both arranged in two along the transverse direction, so that the force acting on the pressing plate 115b is balanced.

[0052] Please refer to Figure 4 , Figure 5 and Figure 7The Y-direction feeder 11 further comprises an adjusting assembly 116, which comprises an adjusting rod 1161 and a handle 1162. Two ends of the adjusting rod 1161 are rotatably arranged on two support plates 111b respectively. Two grooves 11611 are arranged on the adjusting rod 1161, and the two grooves 11611 are located below the second end 111d2 respectively. The handle 1162 is connected with one end of the adjusting rod 1161. The handle 1162 drives the adjusting rod 1161 to rotate by rotating, so as to change the position of the grooves 11611, so that the second end 111d2 is located in the grooves 11611 or outside the grooves 11611. The adjusting rod 1161 rotates and drives the upper pressing wheel 112 to move, so as to adjust the height of the upper pressing wheel 112b, thereby adjusting the gap between the upper pressing wheel 112b and the lower pressing wheel 112a. By adopting the above structure, when it is needed to place materials, the handle 1162 is rotated, so that the second end 111d2 is located outside the grooves 11611, so as to raise the second end 111d2 and the upper pressing wheel 112b, so that the gap between the upper pressing wheel 112b and the lower pressing wheel 112a is enlarged, and the materials are conveniently placed. When it is in normal working condition, the handle 1162 is rotated, so that the second end 111d2 is located in the grooves 11611, and the gap between the upper pressing wheel 112b and the lower pressing wheel 112a is reduced, so that the materials are clamped by the upper pressing wheel 112b and the upper pressing wheel 112b.

[0053] The edge of the lower pressing wheel 112a is provided with a first gear, and the edge of the upper pressing wheel 112b is provided with a second gear. The first gear and the second gear are matched, so that the lower pressing wheel 112a drives the upper pressing wheel 112b to rotate. By adopting the above structure, the upper pressing wheel 112b rotates more smoothly through the cooperation of the first gear and the second gear. The first gear and the second gear are located inside the support plate 111b, so as to avoid interference with the materials.

[0054] Please refer to Figure 3 The Y-direction feeder 11 further comprises a material passing structure 117, which comprises two material passing plates 1171. One material passing plate 1171 is arranged on the output side of the lower pressing wheel 112a, and the other material passing plate 1171 is arranged on the input side of the lower pressing wheel 112a. The two material passing plates 1171 are flush and are fixed on the support plate 111b. By adopting the above structure, the materials are horizontally supported by the two material passing plates 1171, so that the materials can keep flat before and after passing through the lower pressing wheel 112a, thereby making the feeding smooth and the feeding precision high.

[0055] Please refer to Figure 3 , Figure 8 and Figure 9The material passing plate 1171 is provided with a material passing groove 11711 and two mounting grooves 11712. The material passing groove 11711 extends along the conveying direction of the material passing plate 1171. The two mounting grooves 11712 are located on the two sides of the material passing groove 11711 in the transverse direction and are in communication with the material passing groove 11711. The material passing structure 117 further comprises two positioning plates 1172. The two positioning plates 1172 are spaced apart and are arranged in the two mounting grooves 11712 respectively. The lower portion of the positioning plate 1172 is provided with a recess 11721. The two recesses 11721 are matched to limit the two sides of the material in the transverse direction. By using the structure, the material is limited by the two recesses 11721, so that the material is not easy to move in the transverse direction and the vertical direction, and the feeding accuracy is effectively improved. The mounting grooves 11712 facilitate the accurate installation of the positioning plates 1172.

[0056] Please refer to Figure 9 The positioning plate 1172 is provided with a long slot 11722 extending in the transverse direction. A screw is arranged in the long slot 11722. The screw is connected with the material passing plate 1171 and is used to adjust the position of the positioning plate 1172. By using the structure, the position of the positioning plate 1172 can be changed according to the width of the material, so as to adjust the distance between the two recesses 11721.

[0057] The material passing plate 1171 located on the input side of the pressing wheel 112a is provided with a first sensor 1173 above the end away from the pressing wheel 112a. The first sensor 1173 is used to sense whether there is material. The material passing plate 1171 located on the output side of the pressing wheel 112a is provided with a copper wire 1174 above the end away from the pressing wheel 112a. The copper wire 1174 is used to sense whether the material is arching. A PLC controller is connected with the first sensor 1173, the copper wire 1174 and the punch. The PLC controller can control the start and stop of the punch. In the above structure, when the first sensor 1173 cannot sense the material, the first sensor 1173 transmits a signal to the PLC controller to control the stop of the punch and alarm, so as to avoid the damage of the mold and the punch. When the material is arching, the material will touch the copper wire 1174. The PLC controller receives the signal to control the stop of the punch and alarm, so as to avoid the damage of the mold and the punch. In addition, the PLC controller can not be arranged. The data line, the wireless communication module and the like can be electrically connected to the computer of the user. The driving and control software of the punch is installed in the computer. The computer is used to control the operation, so as to reduce the overall cost.

[0058] Please refer to Figure 1 and Figure 2The high-speed punch feeder further comprises an X-direction feeder 12, which comprises a second motor 121 and a module 122. The X-direction feeder 12 is arranged in a diagonal direction between the transverse direction and the longitudinal direction, and the included angle a between the diagonal direction and the longitudinal direction is 120°. The module 122 is arranged in the diagonal direction, and a sliding block 1221 is arranged on the module 122. The sliding block 1221 is connected with the bottom plate 111a, and the second motor 121 is connected with the sliding block 1221 and used to drive the sliding block 1221 and the Y-direction feeder 11 to move back and forth in the diagonal direction. Figure 1 In the embodiment, the x-direction is the transverse direction, the y-direction is the longitudinal direction, and the t-direction is the diagonal direction. Figure 11 As shown in the figure, the two adjacent product positions of the material are staggered, the gap between the product positions is small, more products can be processed, and the material is effectively saved. Figure 12 As shown in the figure, if the X-direction feeder 12 is arranged in the transverse direction, i.e., the sliding block 1221 slides in the transverse direction, the two adjacent product positions are aligned, the gap between the product positions is large, and the material is relatively wasted.

[0059] Please refer to Figure 2 The upper surface of the module 122 is provided with two second sensors 1222, which are respectively arranged on the two sides of the moving direction of the sliding block 1221 and used to sense the stroke of the sliding block 1221 and the Y-direction feeder 11. The two second sensors 1222 are connected with the PLC controller. When the second sensor 1222 senses that the Y-direction feeder 11 exceeds the stroke, a signal is sent to the PLC controller, the punch is stopped and an alarm is given, and the damage of the die is avoided.

[0060] The working process of the high-speed punch feeder of the preferred embodiment of the application is as follows:

[0061] 1. Adjust the distance between the two positioning plates 1172 to match the width of the material.
