Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping parts, and particularly relates to an energy-saving automobile stamping part. Background Art

[0002] Automobile stamping parts are automobile parts made by stamping processing, including many types, such as protective covers, installation boxes, and so on.

[0003] The traditional processing method of automobile stamping parts is to place the original automobile stamping parts on the working table of the stamping machine. After completing the limit fixation of the original automobile stamping parts, the stamping head is used to stamp the original automobile stamping parts. After the stamping is completed, the formed automobile stamping parts are taken out from the working table of the stamping machine to complete the stamping step;

[0004] When the above-mentioned original automobile stamping parts are stamped by the stamping head, depressions will be generated on the surface and they will fit with the inner cavity of the lower die on the working table of the stamping machine. After the stamping is completed, it is necessary to cooperate with the ejection assembly to eject the stamped automobile stamping parts from the lower die of the stamping machine working table to facilitate the operator to take out the automobile stamping parts. Since an additional ejection operation is required after the stamping is completed, additional operation steps will be increased, thereby reducing the stamping efficiency and being more resource-consuming. More importantly, during the process of the original automobile stamping parts being stamped by the stamping head, the surface will be impacted and generate high temperature. It is necessary to additionally use a cooling assembly such as a cooling nozzle to perform surface air cooling on the automobile stamping parts before subsequent processing can be facilitated. Therefore, additional operation steps will also be increased, thereby reducing the stamping efficiency and being more resource-consuming. Content of the Utility Model

[0005] Aiming at the above-mentioned disadvantages of the prior art, the utility model provides an energy-saving automobile stamping part, which can effectively solve the problems raised in the background art.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0007] The utility model provides an energy-saving automobile stamping part, including a stamping seat arranged above a bottom plate. A stamping cavity is opened at the top of the stamping seat. Four cooling pipes are all embedded and installed in the stamping seat. The buffer and reset assembly includes four springs installed between the bottom plate and the stamping seat. It also includes air cylinders fixedly installed at the top of the bottom plate and located in the corresponding springs respectively. An air cavity is opened at the top of each air cylinder. An air pipe is slidably installed in the air cavity. Air holes communicating with the corresponding cooling pipes are opened inside the air pipe. A rubber buffer plate is fixedly installed at the lower bottom of the stamping seat. A plurality of air inlet and exhaust holes communicating with the four cooling pipes are opened on the rubber buffer plate.

[0008] Further, mounting bars are fixedly installed at both ends of the bottom plate, and two symmetrically distributed mounting holes are respectively formed through the mounting bars.

[0009] Further, an air inlet and outlet cavity which is opposite to the position of the rubber buffer plate and has an area smaller than that of the rubber buffer plate is formed through the center of the bottom plate.

[0010] Further, the cooling pipe is designed in a U shape, and both ends are flush with the bottom of the stamping seat.

[0011] Further, the inner diameter of the air cavity is the same as the outer diameter of the air pipe, and the inner diameter of the air hole is the same as the inner diameter of the corresponding cooling pipe.

[0012] Further, a panel cavity communicating with the four cooling pipes is formed at the top of the rubber buffer plate, and a plurality of air inlet and outlet holes are formed through the panel cavity at the lower bottom of the rubber buffer plate.

[0013] The technical solution provided by the present utility model has the following

[0014] Beneficial effects as compared with the known prior art:

[0015] 1. A plurality of springs are installed between the stamping seat and the bottom plate, so that during the process of the stamping seat being stamped by the stamping head, it can be forced to compress to obtain an elastic restoring force. After the stamping head completes stamping, the stamping seat is automatically pushed out by the elastic restoring force of the spring. Without the need to separately eject the stamping seat, it is convenient to take out the stamping seat and the bottom plate from the stamping machine workbench. It initially has the advantages of reducing operation steps, thereby improving stamping efficiency and being relatively resource-saving.

[0016] 2. In order to prevent the springs from being overly compressed or tilted and bent during the stamping process of the stamping head, an air pipe and an air cylinder that are inserted into each other are arranged in each spring. Through the mutual restriction of the air pipe and the air cylinder, together with the buffering protection of the rubber buffer plate at the bottom of the stamping seat, the damage to the stamping seat during the stamping process is reduced. More importantly, during the mutual telescopic sliding of the air pipe and the air cylinder, the air in the air cavity of the air cylinder will enter and exhaust through a plurality of cooling pipes embedded and installed at the bottom of the stamping seat, thereby accelerating the cooling efficiency of the stamping seat body. Without the need to separately cool the stamping seat after stamping, it further has the advantages of reducing operation steps, thereby improving stamping efficiency and being relatively resource-saving.

Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model will be further described below with reference to the embodiments.

[0026] Embodiment 1

[0027] Refer to Figures 1-5, which is the first embodiment of the present utility model, discloses an energy-saving automotive stamping part, including a bottom plate 1 and a stamping seat 2 disposed above the bottom plate 1. A stamping cavity 21 is formed at the top of the stamping seat 2, which is convenient for assembling with other automotive parts. Four cooling pipes 22 are all embedded and installed in the stamping seat 2. The buffer and reset assembly includes four springs 31 installed between the bottom plate 1 and the stamping seat 2. The springs 31 absorb impact energy and obtain elastic potential energy after compression, providing an upward buffer force to the stamping seat 2. It also includes air cylinders 32 fixedly installed at the top of the bottom plate 1 and located inside the corresponding springs 31 respectively. Air cavities 33 are formed at the tops of the air cylinders 32. An air pipe 34 is slidably installed in the air cavity 33. Air holes 35 communicating with the corresponding cooling pipes 22 are formed inside the air pipe 34. A rubber buffer plate 4 is fixedly installed at the bottom of the stamping seat 2. A plurality of air inlet and exhaust holes 42 communicating with the four cooling pipes 22 are formed on the rubber buffer plate 4. Through the air inlet and exhaust holes 42, the relative flow of air between the outside and the air in the air cavity 33 is completed, realizing buffering and shock absorption of the stamping seat and at the same time air-cooling the stamping seat.

[0028] Embodiment 2

[0029] Refer to Figures 1-5 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that installation bars 11 are fixedly installed at both ends of the bottom plate 1. Two symmetrically distributed installation holes 12 are formed through the installation bars 11. An air inlet and exhaust cavity 13 that is opposite to the position of the rubber buffer plate 4 and has an area smaller than that of the rubber buffer plate 4 is formed through the center of the bottom plate 1, ensuring that the rubber buffer plate 4 will be squeezed and abutted against the bottom plate 1 when it descends. The cooling pipes 22 are designed in a U shape, and both ends are flush with the bottom of the stamping seat 2. The inner diameter of the air cavity 33 is the same as the outer diameter of the air pipe 34, ensuring that the air in the air cavity 33 can only enter and exit through the air holes 35. A cooling cavity 23 is formed inside the cooling pipe 22. The inner diameter of the air hole 35 is the same as the inner diameter of the corresponding cooling cavity 23. A panel cavity 41 communicating with the four cooling pipes 22 is formed at the top of the rubber buffer plate 4. A plurality of air inlet and exhaust holes 42 are formed through the panel cavity 41 at the bottom of the rubber buffer plate 4.

[0030] The remaining structures are the same as those in Embodiment 1.

[0031] The working process of the present utility model is as follows:

[0032] First, place the bottom plate 1 flat on the working table of the stamping machine, and pass through the installation holes 12 on the installation bars 11 with relevant limiting structures such as positioning pins to complete the limiting and fixing of the bottom plate 1;

[0033] Secondly, start the stamping machine to control the rapid descent of the stamping head to stamp the stamping cavity 21. During the stamping process, the stamping seat 2 is impacted and the impact energy is absorbed by the spring 31, quickly causing the air pipe 34 in the spring 31 to extend into the bottom of the air cavity 33 in the corresponding air cylinder 32. At the same time, the rubber buffer plate 4 also descends synchronously until it is squeezed against the bottom plate 1, completing the buffer protection for the stamping seat 2. In addition, when the air pipe 34 quickly extends into the bottom of the air cavity 33, the air in the air cavity 33 will be pressed into the air hole 35 and discharged into the panel cavity 41 through the cooling cavity 23, and finally the excess air is discharged from several air intake and exhaust holes 42. The discharge rate is less than the impact speed of the relative sliding of the air pipe 34 and the air cylinder 32. Therefore, it further plays a role in buffering and protecting the stamping seat 2, and at the same time plays a role in air-cooling and cooling the stamping seat 2. When a stamping is completed, the spring 31 elastically returns, pushing the buffer seat 2 upward and causing the air pipe 34 to be withdrawn a certain depth from the corresponding air cylinder 32. At this time, the space in the air cavity 33 increases, and the external space will be drawn back and filled into the air cavity 33 through the air hole 35, the cooling cavity 23, the panel cavity 41 and the air intake and exhaust holes 42. During this process, the air flows reversely in the cooling cavity 23, further completing the air-cooling and cooling of the stamping seat;

[0034] Finally, and after the stamping is completed, the compressed spring 31 elastically returns, automatically pushing up the stamping seat 2, facilitating the final removal of the stamping seat 2 together with the bottom plate 1 from the workbench of the stamping machine.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
