[0001] The utility model relates to the field of door glass guide rail processing devices, in particular to a hydraulic punching machine for processing door glass guide rails. Background Art

[0002] An automotive glass guide rail is one of the important functional components of an automobile. The structure of this component directly affects the passenger's experience of the glass lifting function of the automobile. A hydraulic punching machine is required for processing the door glass guide rail. However, in the existing hydraulic punching machine, after the punching head extrudes an object, some impurities often adhere to the extruded bottom surface, and it cannot be cleaned efficiently and quickly, which affects the subsequent processing quality. Moreover, the punching head generates serious heat after working for a long time, shortening the service life of the punching head. At the same time, after punching, the object gets stuck on the punching head and is not easy to fall off, and there is no collection device for the waste material punched out, which affects the on-site working environment.

[0003] According to a hydraulic punching machine for processing door glass guide rails described in the patent network (the authorized publication number is: CN208788767U), "It includes a workbench, a hydraulic cylinder, a lower die and a jet nozzle; the hydraulic cylinder is fixedly arranged on the workbench through a support frame, a driving shaft is arranged at the bottom of the hydraulic cylinder, and a punching head is fixedly connected to the bottom of the driving shaft; the lower die is fixedly arranged on the workbench, the lower die is located directly below the punching head and the two are mutually adapted, a material blocking and fixing block is arranged on the lower die, a groove for the material to penetrate through is arranged at the bottom of the material blocking and fixing block, a punching hole adapted to the punching head is arranged at the top of the material blocking and fixing block, and the punching hole is communicated with the groove; the jet nozzle is fixedly arranged on the support frame, and the orientation of the jet nozzle is fixedly inclined upward and cooperates with the bottom of the punching head."

[0004] Regarding the above description, the applicant believes that the following problems exist:

[0005] During the use of this utility model, since a punching hole adapted to the punching head is arranged at the top of the material blocking and fixing block, and the punching hole is communicated with the groove, such a structure cannot well prevent the punching waste from falling out of the punching hole along with the trend and falling on the workbench, resulting in equipment dirt, and in serious cases, it will cause damage to the equipment. Therefore, it is necessary to improve a hydraulic punching machine for processing door glass guide rails to solve the above problems. Summary of the Utility Model

[0006] In order to overcome the problem that the existing structure cannot well prevent the punching waste from falling out of the punching hole along with the trend.

[0023] The present utility model will be further described below with reference to the drawings and embodiments.

[0024] Please refer to Figures 1-5, the present utility model provides an embodiment: a hydraulic punching machine for processing a car door glass guide rail, including a frame 1 and a working plate 3 arranged on the frame 1. A cover plate 12 is provided at the top of the working plate 3 and is connected by a column 11. A hydraulic cylinder 4 is provided on the cover plate 12. The output shaft 41 of the hydraulic cylinder 4 can pass through the cover plate 12 and vertically point to the working table 2. A punching head 42 is connected to the bottom of the output shaft 41. Above the working plate 3, there is a working table 2 integrally formed with the working plate 3. A downwardly concave mounting position 21 is provided on the surface of the working table 2. On both sides of the mounting position 21 on the upper surface of the working table 2, there are rubber plates 23. The distance between the two rubber plates 23 is a, and the diameter of the punching head 42 is b, and b / 2≥a>b. By arranging two rubber plates 23 at the mounting position 21, the rubber plates 23 can scrape the iron filings on the surface of the punching head 42. After the punching head 42 passes through the distance a between the two rubber plates 23, it can punch the car glass guide rail. After punching is completed, the punching head 42 moves upward, and the rubber plates 23 can squeeze the punching head 42 to prevent the punching head 42 from taking out the iron filings.

[0025] Please refer to Figures 1-4 , in this embodiment, the mounting position 21 includes a mounting surface 211. The flatness of the mounting surface 211 is less than 0.12. A recessed avoidance position 22 is provided on the surface of the mounting surface 211. A waste box 5 is inserted at the bottom of the avoidance position 22. The waste box 5 includes a receiving bin 51, and the avoidance position 22 is communicated with the receiving bin 51. Ensuring the flatness of the mounting surface 211 can ensure that the car glass guide rail is placed flat, prevent punching from warping and causing product defects. The waste after punching can fall from the avoidance position 22 into the waste box 5 for recycling. On one side of the punching head 42 close to the output shaft 41, there is a threaded hole 421 penetrating the diameter direction of the punching head 42. A cooling box 6 is provided on the top of the cover plate 12. The cooling box 6 contains coolant. The cooling box 6 includes a cooling pipe 61. The cooling pipe 61 can guide the coolant in the cooling box 6 to one side of the threaded hole 421. The cooling pipe 61 includes a speed regulating valve. When the punching machine runs quickly, the coolant in the cooling box 6 can quickly cool the punching head 42 to prevent the punching head 42 from fatigue fracture. There are no less than three spirit levels 121 on the top of the cover plate 12. In order to prevent the coolant from dripping randomly onto the working plate 3, the punching machine needs to be adjusted to be horizontal so as to ensure that the coolant passes through the distance a.

[0026] Please refer to Figures 4-5, in this embodiment, a cross bar 43 is provided at the bottom of the output shaft 41. Guide rods 44 perpendicular to the downward direction are provided on both sides of the cross bar 43. The guide rods 44 can pass through the working plate 3. The position of the punching head 42 can be located through the guide rods 44 to prevent the output shaft 41 from deviating. The rubber plate 23 is made of butadiene rubber, and the rubber plate 23 is fixed above the workbench 2 by a pressing plate 24. The rubber plate 23 made of butadiene rubber can effectively avoid the punching head 42 and at the same time can retain the dirt on the punching head 42. The waste box 5 is provided with a handle 52. The waste box 5 equipped with the handle 52 enables the user to smoothly pull out the waste box 5, improving work efficiency.

[0027] During operation, the door glass guide rail flowing out from the previous station's automated line body is pushed onto the mounting surface 211 of the mounting position 21 of this punching machine. Subsequently, the hydraulic cylinder 4 controlled by the programmable logic controller extends the output shaft 41 downward. The guide rods 44 control the punching head 42 on the output shaft 41 to be precisely pressed downward without deviation. During the downward pressing of the punching head 42, it will pass through the gap a formed by the two rubber plates 23. When passing through, the rubber plates 23 will deform, and the two rubber plates 23 will tightly press against the radial surface of the punching head 42. When the punching head 42 continues to press downward, the punching operation on the door glass guide rail is completed. After that, the punching head 42 moves upward and is pulled out from the automotive glass guide rail. Since the rubber plate 23 is fixed by the pressing plate 24, the deformation ability of the rubber plate 23 is smaller in the area closer to the pressing plate 24. Therefore, when the punching head 42 is withdrawn, the automotive glass guide rail will not be carried out from the mounting position 21. During the punching operation, one side of the through-threaded hole 421 receives the coolant from the cooling tank 6 through the cooling pipe 61. Subsequently, the coolant will flow out from the other side of the threaded hole 421 and drip downward along the punching head 42. The reason why it can drip instead of gushing out all at once is that a speed control valve is also connected to the cooling pipe 61 to control the outflow speed of the coolant. The coolant dripping along the punching head 42 will pass through the gap a formed by the two rubber plates 23 and will not dirty the working plate 3. The specific reason is that at least three spirit levels 121 are provided on the cover plate 12 of this punching machine. When the engineer installs and adjusts, the device is adjusted to a horizontal state. Therefore, the coolant dripping from the punching head 42 will directly pass through the gap a. This punching machine can not only work within the automated production line body but also be manually operated. The reason for b / 2≥a>b here is that when a<b / 2, the squeezing force of the rubber plate 23 on the punching head 42 is insufficient. When a>b, the cleaning effect of the rubber plate 23 scraping the surface of the punching head 42 is poor, and waste will also be carried out from the gap a.

[0028] Through the above steps, the punch head 42 will pass through the gap a formed by the two rubber plates 23 during the downward pressing process. The rubber plates 23 will be deformed during the passing process, and the two rubber plates 23 will be tightly pressed against the radial surface of the punch head 42. When the punch head 42 continues to press down, the punching operation of the door glass guide rail is completed. Then the punch head 42 moves upward and is pulled out from the car glass guide rail. Since the rubber plate 23 is fixed by the pressing plate 24, the closer the rubber plate 23 is to the pressing plate 24, the smaller the deformation capacity is. Therefore, when the punch head 42 is pulled out, the car glass guide rail will not be brought out from the installation position 21, so as to solve the problem that the existing structure cannot well prevent the punching waste from being brought out of the punching hole.
