To normalize the relative positions of the beam arm 320 and the base plate 310, the beam arm 320 has one of the folded edges 311 as a starting point, and the other folded edge 311 is far from the starting point of the beam arm 320. For the same batch of wire harness holders 300, since the position of the folded edge 311 thereof is not changeable, the starting point of the wire harness arm 320 is defined.

It should be noted that, for convenience of description, the fold 311 distant from the start point of the beam line arm 320 is referred to as a far point fold 301, and the fold 311 defining the start point of the beam line arm 320 is referred to as a near point fold 302.

On the other side, the upper die assembly 200 is sequentially connected with an upper mounting plate 210, an upper base plate 220 and an upper die holder 230 from top to bottom, the upper die holder 230 is located right above the lower die holder 130, the upper base plate 220 is provided with an upper mounting position capable of being embedded into the upper die holder 230, the upper die holder 230 is provided with four punches 231 extending downwards at corresponding positions of the folded edges 311, the punches 231 are provided with punching grooves 232 capable of being pressed on the folded edges 311, and when the folded edges 311 are pressed on by the punches 231, the inner walls of the folded edges 311 can be tightly attached to corresponding wire binding arms 320 so as to realize fixed connection of the wire binding arms 320 and the bottom plate 310.

As shown in fig. 2 and 3, in order to realize the vertical guiding of the upper die assembly 200 and the lower die assembly 100, the upper mounting plate 210 and the upper backing plate 220 are fixedly connected with two guide posts 221 extending downward, the lower mounting plate 110 and the lower backing plate 120 are provided with two guide holes 121 at corresponding positions of the guide posts 221, and when the upper die assembly 200 is pressed downward toward the lower die assembly 100, the upper die assembly 200 and the lower die assembly 100 are guided vertically through the cooperation of the guide posts 221 and the guide holes 121, so as to ensure that the punch 231 can be aligned to the folded edges 311 along the vertical direction.

As shown in fig. 4, in order to enable the wire harness arm 320 to adaptively adjust the positions thereof after the two folded edges 311 are inserted, each of the first positioning portions 131 is provided with a mounting groove 134 on the outer side of the corresponding folded edge 311, the mounting groove 134 is defined by the first positioning portion 131 and the lower die holder 130 together, and the mounting groove 134 has a receiving space in which the magnet 400 can be placed. The outer side of the flange 311 refers specifically to the side away from the bottom plate 310, i.e., the periphery of the flange 311. Since the tail of the wire harness arm 320 is a main body portion of the wire harness, the position thereof is more important than the starting position of the wire harness arm 320, and therefore the magnet 400 is provided at least on the outer side of the far spot flange 301. Because the first positioning portion 131 is provided with the magnet 400 at the outer side of the far point folded edge 301, and the magnet 400 has an attraction effect on the wire harness arm 320 of the wire harness bracket 300, the wire harness arm 320 can be adaptively pressed close to the far point folded edge 301 of the wire harness bracket 300, so that the position of the wire harness arm 320 can be limited within a preset range, the operation of fine tuning the wire harness arm 320 is omitted, and the production efficiency and the production precision of the wire harness bracket 300 are improved, so that the requirement of mass production is met.

Meanwhile, since the different lower die holders 130 have the mounting grooves 134 of different sizes, in order to fit the mounting grooves 134 of different sizes, the magnet 400 is composed of a plurality of magnetic grains 410, the plurality of magnetic grains 410 are filled in the mounting grooves 134 by being integrated into zero, and the magnetic force of the magnet 400 can be enhanced.

In some embodiments of the present utility model, as shown in fig. 2 and 3, in order to avoid the occurrence of a stroke, the upper pad 220 is provided with two limiting posts 222 extending downward, and the lower pad 120 is planar at corresponding positions of the limiting posts 222. When the limiting post 222 abuts against the plane of the lower die assembly 100, the upper die assembly 200 cannot continue to move toward the lower die assembly 100, so as to avoid damage to the stamping die 10 caused by failure.

In some embodiments of the present utility model, the guide post 221, the limit post 222 and the punch 231 of the stamping die 10 are made of high-rigidity materials by using an industrial equipment bridge deformation prevention method, so as to ensure arch deformation caused by large tonnage force and molecular structure deformation caused by long-term production; all the templates of the stamping die 10 are made of high-hardness materials so as to ensure arch transformation caused in the compression process, greatly improve long-time load on the stamping power source under the action of gravity and prolong the service life of the stamping power source.

As shown in fig. 5 and 6, the punching apparatus according to the second aspect of the present utility model, which includes the wire harness support punching die according to the above-described first aspect of the present utility model, further includes the frame 20 and the pressure cylinder 30, the pressure cylinder 30 may be selected as a gas-liquid pressure cylinder, which integrally combines the oil pressure cylinder with the pressure booster, uses pure air pressure as a power source, and increases the air pressure to several tens times of pressure effect by the ratio of the different compression cross-sectional areas of the pressure booster and the pascal principle. The gas-liquid booster cylinder is simple to operate, has no trouble of hydraulic temperature rise or high noise, can save more than 30% of energy compared with the traditional hydraulic cylinder, further reduces the cost, and can meet the requirements of high speed and high output.

Specifically, the pressure cylinder 30 and the lower mounting plate 110 of the lower die assembly 100 are both mounted on the frame 20, the pressure cylinder 30 is located right above the lower die assembly 100, the pressure cylinder 30 is provided with a telescopic rod 31 that can be extended and retracted up and down, and the telescopic rod 31 is fixedly connected with the upper mounting plate 210 of the upper die assembly 200, so that the upper die assembly 200 can be driven by the pressure cylinder 30.

Further, the pressure cylinder 30 is connected to the air pipe sequentially through a pressure regulating valve 32 and an air source processor 33, the air source processor 33 is used for performing water-air separation and oiling treatment on the input dry compressed air again, and the pressure regulating valve 32 can perform stepless regulation on the input air pressure, so that stepless regulation and control of the punching pressure within a specified range are realized.

After the worker positions the wire harness support 300 on the lower die holder 130, the press button of the control panel 21 drives the pressurizing cylinder 30 to execute the stamping action, and at this time, the upper die assembly 200 is gradually pressed downward toward the lower die assembly 100 under the driving of the pressurizing cylinder 30 until all the punches 231 press the corresponding folded edges 311. As the punch 231 gradually presses the flange 311, the pressure of the pressure cylinder 30 tends to be low to high with the formation of the pressure gauge 22, and after the pressure exceeds a preset value, the pressure cylinder 30 is held for a preset period of time, after which the pressure cylinder 30 is returned. In the above-mentioned process, the present utility model can limit the size of the stamping force according to the preset value, so as to meet the stamping requirements of different wire harness brackets 300, and the limit post 222 is not required to be used for up and down limiting, which is beneficial to prolonging the service life of the stamping die 10.

In some embodiments of the present utility model, since the worker needs to manually place the bottom plate 310 and the harness arm 320 on the lower die holder 130, in order to avoid a safety accident caused by accidental activation of the punching device, the frame 20 is provided with a safety grating 40 at the periphery of the harness bracket punching die, and a grating area of the safety grating 40 is located between the worker's station and the lower die holder 130, and the punching device can be normally activated only when the safety grating 40 does not detect a human body, otherwise, is always in a standby state.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
