Description

Technical Field

[0002] With the development of flight technology, various types of aircraft have appeared one after another, including small aircraft, helicopters, gliders, etc. In order to complete complex flight control during the flight of the aircraft, multiple sets of flight control components need to be installed inside the aircraft. When setting, the control components are integrated and installed on the upper part of the specific onboard seat of the aircraft. Considering the working heat dissipation of the control components, a heat dissipation structure needs to be set at the installation location of the components. The heat dissipation of the components mainly relies on the heat sink for heat conduction. The structure of the heat sink is mostly a sheet-like structure of a special form of metal plate. Due to its structural characteristics, the blanking process is often used in processing. Blanking is also called punching. It is a stamping process that uses a hydraulic device to drive the cutter head to separate part of the material or process parts from another part of the material, workpiece or waste. It is widely used in the field of metal processing.

[0003] During production and processing, the heat sink is punched and formed by the equipment and separated from the material plate. Considering the utilization rate of the material plate, the punching device mostly adopts an equidistant punching processing method.

[0031] As attached Figure 3 As shown, in order to prevent the driving wire 13 from detaching from the upper part of the wire guide wheel 12 when moving back, an anti-detachment bracket 20 is provided on the side of the wire guide wheel 12, and the anti-detachment bracket 20 is fastened to the side of the cross plate support 9 by bolts, and the driving wire 13 is movably inserted and installed on the inner side of the wire through hole provided on the upper part of the anti-detachment bracket 20.

During the displacement, the photoelectric sensor 21 can detect the displacement of the sheet metal and judge the displacement state of the sheet metal to avoid the occurrence of punching accidents.

[0032] Working principle or structural principle: The material sheet used in this device is long and strip-shaped. Considering the traction force and processing convenience, the length of a single material sheet does not exceed two meters. During processing, the end of the material sheet is first manually fed into the interior of the blanking device, and then the blanking head seat 3 moves down under the drive of the driving cylinder 1, and the material sheet is separated from the upper part of the material sheet through staggered blanking of the slots, and falls into the material bin on one side of the workpiece collection box 23 through the guidance of the lower discharge port 8 at the lower part of the lower blanking seat 4. At the same time, when the convex tooth push block 22 moves down, it is alternately embedded with the semicircular protrusion 26 on the side of the workpiece collection box 23. The workpiece collecting box 23 is connected by the clamping connection. Through the lateral elastic pushing of the push and spring push block 25, the workpiece collecting box 23 can be briefly moved and shaken. The shaking is divided into two groups, upward and downward, and the shaking displacement does not exceed the notch docking range. The workpiece pieces that are raised in the workpiece collecting box 23 can be shaken off by shaking to ensure that the upper and lower groups of workpiece pieces are stably fitted. Then, the upper punching seat 2 is moved up and opened, and the material plate is pushed to the next station. After completing another set of punching processing, the side of the first punching notch is made to contact and fit with the side of the flip push block 14, and the processing preparation work is completed; During punching, the driving cylinder 1 drives the upper punching seat 2 to move downward. During the process, the pulling force of the driving wire 13 is lost, and the pushing slide block 10 is pulled by the traction spring 11 to slide, and the material plate is driven to shift and move horizontally by the push of the flip push block 14. When the end of the pushing slide block 10 contacts the end of the stroke adjustment bolt 18, the material sheet reaches the next punching station and stops moving. At this time, the punching head seat 3 and the material sheet are in a non-punching contact state, and then the punching head seat 3 continues to move downward and contacts the material sheet to complete the punching work. Then the upper punching seat 2 moves upward, and during the upward movement, the driving wire 13 is pulled to drive The pushing slider 10 moves back and resets, and the traction spring 11 is stretched and stored. During the movement, the pressure of the material plate pushes the flip push block 14 to automatically flip down and retract to avoid dragging the material plate. After it coincides with the punching groove on the upper part of the material plate, the flip push block 14 is pushed by the micro spring 16 to automatically flip up and support the side of the groove of the punching groove. At this time, the upper punching seat 2 reaches the upper stop position, completing the preparation work of the lower group of punching, and then repeating the above actions to complete the single-sided punching processing of the material plate, and then turning the material plate over and opening the workpiece collection box 23 to flip it over, and repeating the above operations to perform double-sided punching processing on the material plate.

[0033] In summary, the punching device adopts an equidistant pushing type automatic pushing structure, and utilizes the flip pushing block 14 arranged on the upper part of the cross plate support 9 to push the material plate structure alternately and equidistantly. The flip pushing block 14 is unidirectionally flipped and installed with the pushing slide block 10. When the pushing slide block 10 moves back and resets, the material receiving plate pushes the flip pushing block 14 to automatically flip down and retract. After it coincides with the punching groove on the upper part of the material plate, it is pushed by the micro spring 16 to automatically flip up and support the notch edge of the punching groove. The pushing and displacement of the material plate can be automatically completed by driving the pushing slide block 10. The structure is simple and the operation is reliable. The driving wire 13 and the traction spring 11 are respectively installed at both ends of the pushing slide block 10. The driving wire 13 is guided by the wire guide wheel 12 and connected and installed with the upper punching seat 2. When the upper punching seat 2 moves up, the driving wire 13 pulls the driving push slide block 10 to move back and reset, and the traction spring 11 is stretched and stored, and the upper punching seat 2 moves down. The pushing slide block 10 is pulled by the traction spring 11 to make a sliding motion of a fixed stroke, and the pushing and pressing of the flip push block 14 can automatically complete the pushing and replacement of the material plate. The whole work is automatic without human participation, which can save manpower and improve the finished product quality and production efficiency of the workpiece. A workpiece collection box 23 is arranged inside the support base 5, and the workpiece collection box 23 is installed inside the support base 5 by the spring push block 25. The workpiece collection box 23 can be used to collect the workpieces that have fallen after punching, which is convenient for subsequent processing and use, and semicircular protrusions 26 are arranged on the front and rear sides of the workpiece collection box 23. With the downward push of the convex tooth push block 22 connected to the upper punching seat 2 and the lateral elastic push of the spring push block 25, the workpiece collection box 23 can be briefly shaken laterally, and the workpiece material sheets that are raised in the workpiece collection box 23 can be shaken off by shaking, so as to realize the stable collection and storage of the material sheets.
