[0002] In industries such as steel structures and power towers, different sheet metal parts need to be typed and drilled in order to install and fix other components, or for ventilation, drainage and other occasions. Before typesetting and drilling, the sheet metal raw materials should first be positioned and clamped through the loading workbench, end positioning device and clamping mechanism, and then typed and drilled through the feeding device, typesetting unit, drilling unit, etc., and finally the finished sheet metal parts are sent to the unloading workbench.

[0003] The existing plate typing and drilling production line usually consists of a typing unit, a drilling unit, a loading workbench (including an end positioning device), a feeding device (including a set of clamping mechanisms), an intermediate roller, a unloading workbench and other mechanisms. Generally, the plate raw material is first placed on the loading workbench, and aligned and clamped by the end positioning device and the clamping mechanism; then the plate raw material is sent to the typing unit or the drilling unit through the feeding device for typing or drilling respectively, and finally the finished plate is sent to the unloading workbench through the feeding device.

[0004] The above-mentioned feeding device has the following problems during use:

[0005] Since the feeding device only includes one set of clamping mechanisms, the sheet materials can only be typed or drilled in sequence, which greatly reduces the processing efficiency of the production line. Utility Model Content

[0010] Furthermore, a guide column is provided between the base and the movable frame bracket.

[0011] Furthermore, the first driving mechanism and the second driving mechanism are both composed of a slide plate slidably connected to the top of the feeding guide rail and a driving motor fixedly connected to the slide plate. A rack is fixedly connected to the feeding frame, and the rack is distributed in a direction parallel to the length of the feeding guide rail. The output shafts of the driving motors of the first driving mechanism and the second driving mechanism are both connected through gear-rack meshing transmission.

[0012] Furthermore, the first clamping mechanism and the second clamping mechanism are each composed of at least one set of hydraulic clamps, and hydraulic positioning components are provided at both ends of the inner side of the hydraulic clamps, and a connecting plate for connecting to a driving mechanism is fixedly connected to the outer side.

[0046] like Figure 1 and Figure 2 The plate typing and drilling production line shown includes a feeding device 1 and a loading workbench 2, a typing unit 4, an intermediate roller 5, a drilling unit 6, and a unloading workbench 7, which are located on one side of the feeding device 1 and are arranged in sequence along the length direction of the feeding device 1. The loading workbench 2 is located in front of the typing unit 4, an end positioning device 3 is arranged between the loading workbench 2 and the typing unit 4, and a plate fixing device 12 is arranged under the intermediate roller 5.

[0047] Specifically, Figure 4 and Figure 5 As shown, the feeding device 1 includes a plurality of feeding racks 101, a feeding guide rail 102 and a gear 103. The feeding guide rail 102 is horizontally distributed along the front-to-back direction. The plurality of feeding racks 101 are evenly fixed below the feeding guide rail 102. The gear rack 103 is fixedly connected to the feeding guide rail 102 and distributed along the length direction parallel to the feeding guide rail 102. The first driving mechanism 9 and the second driving mechanism 11 are respectively arranged at the front and rear positions of the feeding guide rail 102. The inner sides of the first driving mechanism 9 and the second driving mechanism 11 are respectively fixedly connected with the first driving mechanism 9 and the second driving mechanism 11. A clamping mechanism 8 and a second clamping mechanism 10, the first driving mechanism 10 and the second driving mechanism 11 are both composed of a slide plate 14 and a driving motor 13, the slide plate 14 is slidably connected to the top of the feeding guide rail 102, the driving motor 13 is fixedly connected to the top of the slide plate 14, and the power output shaft of the driving motor 14 is fixedly connected with a gear, and the gear is meshingly connected with the rack 103. The first driving mechanism 9 and the second driving mechanism 11 can respectively drive the first clamping mechanism 8 and the second clamping mechanism 10 to move along the length direction of the feeding guide rail 102.

[0048] like Figures 4 to 6 As shown, the first clamping mechanism 8 and the second clamping mechanism 10 each include two groups of hydraulic clamps 15, the outer side surface of the hydraulic clamp 15 is fixedly connected with a connecting plate 17, the connecting plate 17 is fixedly connected to the slide plate 14, and the front and rear ends of the inner side surface of the hydraulic clamp 15 are respectively fixedly connected with a group of hydraulic positioning components 16, the hydraulic positioning component 16 is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is fixed to the hydraulic clamp 15, the movable end is distributed toward the loading workbench 2 and is fixedly connected with a positioning column, the hydraulic cylinder can drive the positioning column to extend and retract in the width direction of the plate material 19, that is, the left and right directions, and when the positioning column is in the extended position, the four groups of positioning columns of the first clamping mechanism 8 are in the same plane to align and position the side edges of the plate material 19.

[0049] The end positioning device 3 is as follows Figure 2 and Figure 3 As shown, it includes a positioning bracket 301, a positioning cylinder 302 and a positioning plate 303. The positioning bracket 301 is located at the lower position between the loading workbench 2 and the typing unit 4. The axis of the positioning cylinder 302 is distributed along the vertical direction. Its cylinder body is fixedly connected to the positioning bracket 301, and the movable end is fixed to the positioning plate 303. The positioning plate 303 is located between the loading workbench 2 and the typing unit 4. The movement of the positioning cylinder 302 can drive the positioning plate 303 to move up and down to extend a certain height above the surface of the loading workbench 2, thereby facilitating the positioning of the rear end portion (i.e., the end close to the typing unit 2) of the sheet material 19, and except for the loading positioning, the positioning plate 303 is located below the surface of the loading workbench 2 in other cases.

[0050] The plate fixing device 12 is as follows Figure 1 , Figure 2 as well as Figure 7 As shown, it includes a base 1201, a moving frame 1202, and a lifting cylinder 1203. The base 1201 is arranged below the middle roller 5. The cylinder body of the lifting cylinder 1203 is fixedly connected to the top of the base 1201. The axis of its piston rod is distributed in the vertical direction and the upper end is fixedly connected to the moving frame 1202. Two groups of guide columns 1204 are arranged between the bottom end of the moving frame 1202 and the upper end of the base 1201. The two groups of guide columns 1204 are symmetrically arranged on the left and right sides of the lifting cylinder 1203. A plurality of groups of fixed units are distributed at intervals from left to right on the upper end of the moving frame 1202. The intervals between the fixed units are the same as the gaps on the middle roller 5, so as to facilitate the up and down movement driven by the lifting cylinder 1203. Each group of fixed units includes two groups of electromagnets 1207. The lower end of the electromagnet 1207 is fixedly connected to a magnet mounting frame 1206. The magnet mounting frame 1206 is connected to the moving frame A telescopic spring 1205 is connected between the upper end surfaces of 1202. The movement of the lifting cylinder 1203 can drive the electromagnet 1207 on the movable frame 1202 to extend above the intermediate roller 6 so that it can be fixed with the lower end surface of the sheet material 19 after power is turned on. In addition, in the present embodiment, when the lifting cylinder 1203 drives the movable frame 1202 to rise, the upper end surface of the electromagnet 1207 is 3 mm higher than the upper end surface of the intermediate roller 5, thereby reducing the vertical distance between the electromagnet 1207 and the lower end surface of the sheet material 19, so as to facilitate the stable connection between the electromagnet 1207 and the sheet material 19. After the sheet material 19 is fixed with the electromagnet 1207, the sheet material 19 compresses the telescopic spring 1205 under the action of gravity until the lower end surface of the sheet material 19 contacts the upper end surface of the intermediate roller 5, so as to ensure the level of the sheet material 19 and reduce the collision between the sheet material 19 and the intermediate roller 5.

[0051] The working principle of this device is as follows:

[0052] First, the positioning cylinder 302 of the end positioning device 3 is actuated to drive the positioning plate 303 to rise, so as to position the rear end of the sheet material 19, and the side of the sheet material 19 is aligned and positioned by the four sets of hydraulic positioning components 16 on the first clamping mechanism 8. The sheet material 19 starts to be loaded from the loading workbench 2, and the side of the sheet material 19 is clamped by the hydraulic clamp 15 of the first clamping mechanism 8; the first driving mechanism 9 drives the first clamping mechanism 8 and the sheet material 19 to move backward to the typing unit 4 station After typing is completed, the first driving mechanism 9 drives the first clamping mechanism 8 and the sheet material 19 to continue to move backward to the position above the sheet fixing device 12. At this time, the lifting cylinder 1203 is actuated to drive the movable frame 1202 to move upward, and the electromagnet 1207 rises to 3 mm above the middle roller 5. At the same time, the electromagnet 1207 is energized, and the sheet material 19 is fixed by multiple groups of electromagnets 1207. Then the hydraulic clamp 15 of the first clamping mechanism 8 is released, and the hydraulic pressure on the hydraulic positioning assembly 16 is released. The pressure cylinder drives the positioning column away from the side of the sheet material 19 to avoid interference and collision with the sheet material 19 during the resetting process. The first driving mechanism 9 drives the first clamping mechanism 8 to return to the loading position; then the second driving mechanism 11 drives the second clamping mechanism 9 to move to the position of the sheet fixing device 12. After moving into position, the hydraulic positioning component 16 on the second clamping mechanism 9 is actuated to align the side of the sheet material 19, and the hydraulic clamp 15 is actuated to clamp the side end of the sheet material 19. After alignment and clamping, the electromagnet 1207 is powered off, and the lifting cylinder 1203 drives the moving frame to move down to the bottom of the middle roller 5. Then the second driving mechanism 11 drives the second clamping mechanism 10 and the sheet material 19 to continue to move backward until the drilling station of the drilling unit 6 is used for drilling. After drilling is completed, it continues to move backward to the position of the unloading workbench 7. Finally, the hydraulic clamp 15 of the second clamping mechanism 10 is released, and the hydraulic positioning component 16 retreats. The processed sheet product 20 is moved into the finished material frame by manual or material transport mechanism, and reciprocating operation is performed.

[0053] The device is provided with two sets of clamping mechanisms and a plate fixing device 12 located at the middle roller 5 as a plate handover platform, which can realize the typing and drilling operations of the plate at the same time, and effectively improves the plate processing efficiency.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
