Description

Technical Field

[0001] This invention relates to the field of automotive hardware processing technology, and more specifically, to a new energy vehicle bridge forming mold and its application method. Background Technology

[0002] The chassis is the most important load-bearing component in a car, and the bridge is one of its key parts, playing a vital role in load-bearing. Bridges are usually stamped from low-alloy steel plates, with a generally channel-shaped cross-section that is narrow, long, and curved. Currently, the positioning molds used for positioning during the stamping process of automotive bridges are not ideal due to the irregular shape of the product and the considerable depth of the channel itself. Simply relying on positioning pins or similar tools is insufficient to achieve a satisfactory positioning effect. Therefore, a new energy vehicle bridge forming mold and its application method are needed for positioning during bridge processing. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a new energy vehicle bridge forming mold and a method for applying the new energy vehicle bridge forming mold, in view of the above-mentioned defects of the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A molding die for a new energy vehicle bridge frame is constructed, comprising a lower die, wherein a first contouring positioning block, a second contouring positioning block, a third contouring positioning block, and a fourth contouring positioning block are sequentially arranged on the lower die; the first and fourth contouring positioning blocks are respectively used for contouring positioning of the two ends of the vehicle bridge frame; the second and third contouring positioning blocks are used for contouring positioning of the middle of the vehicle bridge frame; a first contouring floating block is arranged between the first and second contouring positioning blocks; and a third and fourth contouring positioning block are arranged between... A second contour floating block is provided between the first and second contour floating blocks; positioning blocks and positioning pins are provided on both sides of the upper surface of the first and second contour floating blocks; an air-expanding positioning component is connected between the second and third contour positioning blocks, the air-expanding positioning component includes an air-expanding tube assembly, an air-expanding unit for inflating and deflating the air-expanding tube assembly, and a control unit for triggering the operation of the air-expanding unit. The air-expanding tube assembly is strip-shaped and is composed of multiple segments of air-expanding tubes with adjustable angles. The control unit is triggered by the first and second contour floating blocks together.

[0006] The new energy vehicle bridge forming mold of the present invention includes two adjacent air expansion tubes connected by a hose; a locking screw is fixed on the lower surface of the air expansion tube, and an anti-slip pad is sleeved on the locking screw; the lower mold is provided with an installation chamber for installing the inflation / deflation unit, and the lower end of the locking screw passes through the installation chamber and is sleeved with a locking nut.

[0007] The new energy vehicle bridge forming mold of the present invention includes an inflation / deflation needle tube inserted inside the locking screw, which is connected to the air expansion tube and the inflation / deflation end of the inflation / deflation unit.

[0008] The new energy vehicle bridge forming mold of the present invention includes a control unit comprising a first distance sensor for detecting the position of the first conforming floating block and a second distance sensor for detecting the position of the second conforming floating block, and controlling the operation of the inflation / deflation unit based on the signals received from the first distance sensor and the second distance sensor.

[0009] The new energy vehicle bridge forming mold of the present invention has a first receiving hole for installing the first distance sensor and a second receiving hole for installing the second distance sensor on the side wall of the mounting chamber.

The side punch is obliquely slidably disposed on the lower mold. The punch seat is provided with a through hole for the adjacent hose to pass through.

[0012] A method for applying a molding die for a new energy vehicle bridge, wherein the method includes the following steps:

[0013] The workpiece is gripped and moved by the robot and placed on the first and second contour floating blocks. The positioning blocks and positioning objects on the first and second contour floating blocks provide coarse positioning and support for the workpiece.

[0014] When the mold is closed, the upper mold moves downward, the pressure plate on the upper mold holds the workpiece, and drives the first and second contour floating blocks to move downward. After the workpiece is in place, it is further positioned by the first contour floating block, the second contour floating block, the first contour positioning block, the second contour positioning block, the third contour positioning block and the fourth contour positioning block.

[0015] At the same time, the first and second contour floating blocks trigger the control unit, and the inflation and deflation unit operates to inflate the air expansion tube assembly and maintain the pressure.

[0017] The beneficial effects of this invention are as follows: the workpiece is gripped and moved by a robotic arm and placed on the first and second contour floating blocks. The positioning blocks and positioning targets on the first and second contour floating blocks provide coarse positioning and support for the workpiece. When the mold is closed, the upper mold moves downward, the pressure plate on the upper mold holds the workpiece, and drives the first and second contour floating blocks to move downward. After moving to the correct position, the workpiece is further positioned by the first, second, first, second, third, and fourth contour floating blocks. At the same time, the first and second contour floating blocks trigger the control unit, and the inflation / deflation unit operates to inflate the air expansion tube assembly and maintain pressure. The air expansion tube assembly expands to position the middle section of the workpiece. When the mold is opened, the first and second contour floating blocks reset by the action of elastic elements and release the trigger state of the control unit. The inflation / deflation unit operates to deflate the air expansion tube assembly.

[0018] By applying the method of this application, the material is received and positioned by the first and second contour floating blocks during the feeding stage. During the mold closing stage, the first, second, first, second, third, and fourth contour floating blocks are used for further positioning. The air expansion tube assembly is used for inflation positioning and state maintenance. This method can effectively achieve the positioning and processing of long and narrow hardware parts such as automotive bridges. Moreover, the air expansion tube assembly has a certain degree of adaptability and can be applied to the processing of various workpieces. It can effectively reduce mold costs. The air expansion tube assembly can also absorb the lateral stress during product processing to a certain extent, thereby improving the stability of product processing. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0023] The preferred embodiment of the new energy vehicle bridge forming mold of the present invention, such as Figure 1 As shown, see also Figure 2 The system includes a lower mold 1, on which a first contouring positioning block 10, a second contouring positioning block 11, a third contouring positioning block 12, and a fourth contouring positioning block 13 are sequentially arranged. The first contouring positioning block 10 and the fourth contouring positioning block 13 are used for contouring positioning of both ends of the vehicle bridge 4, respectively. The second contouring positioning block 11 and the third contouring positioning block 12 are used for contouring positioning of the middle (near the end) of the vehicle bridge 4. A first contouring floating block 14 is arranged between the first contouring positioning block 10 and the second contouring positioning block 11, and a second contouring floating block 15 is arranged between the third contouring positioning block 12 and the fourth contouring positioning block 13. The purpose of this design is that the first contouring floating block 14 is contacted by the first contouring positioning block 10 and the second contouring positioning block 11. The two sides of the workpiece are positioned relatively accurately by relying on the third contour positioning block 12 and the fourth contour positioning block 13 to position the two sides of the workpiece in contact with the second contour floating block 15. Positioning blocks 140 and positioning pins 141 are provided on both sides of the upper surface of the first contour floating block 14 and the second contour floating block 15. An air expansion positioning component 2 is connected between the second contour positioning block 11 and the third contour positioning block 12. The air expansion positioning component 2 includes an air expansion tube component 20, an air inflation / deflation unit 21 for inflating and deflation of the air expansion tube component 20, and a control unit for triggering the operation of the air inflation / deflation unit.

The positioning blocks 140 and positioning pins 141 on the first contour floating block 14 and the second contour floating block 15 provide coarse positioning and support for the workpiece.

[0025] When the mold is closed, the upper mold moves downwards. The pressure plate on the upper mold (using a contouring pressure plate) holds the workpiece and drives the first contouring floating block 14 and the second contouring floating block 15 to move downwards. After moving to the correct position, the workpiece is further positioned by the first contouring floating block 14, the second contouring floating block 15, the first contouring positioning block 10, the second contouring positioning block 11, the third contouring positioning block 12, and the fourth contouring positioning block 13.

The air expansion tube assembly 20 expands to position the middle section of the workpiece.

[0027] When the mold is opened, the first contour floating block 14 and the second contour floating block 15 are reset and released from the trigger state of the control unit by the action of the elastic element (the spring of the floating block). The inflation and deflation unit 21 runs to deflate the air expansion tube assembly 20.

The air expansion tube assembly 20 is used for inflation positioning and state maintenance. This method can effectively achieve the positioning and processing of long and narrow hardware parts such as automotive bridges. Moreover, the air expansion tube assembly has a certain degree of adaptability and can be used for processing various workpieces. It can effectively reduce mold costs. The air expansion tube assembly can also absorb the lateral stress during product processing to a certain extent, thereby improving the stability of product processing.

This design allows for quick adjustment of the orientation of the air expansion tube 200 through the cooperation of the locking nut 17 and the locking screw 202. The anti-slip pad 203 is used to prevent the locking screw 202 from loosening. The inflation / deflation needle tube 204 can easily inflate and deflate the air expansion tube 200. The structure is reasonable and compact, occupying little space. Furthermore, the lower mold 1 is provided with a detachable cover plate 18 for the sealing chamber 16.
