DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-Figure 6 The present invention provides a punching device for automobile parts production, comprising:

[0029] A base 1, the top of the base 1 is fixedly connected with a die base 10 for placing automobile special-shaped parts, the bottom of the die base 10 is provided with a punching groove 12, and the top of the base 1 is also provided with a punching assembly, and the punching assembly is arranged corresponding to the punching groove 12;

[0030] The punching and grinding assembly includes a horizontally arranged grinding disc 26. A lifting control mechanism is arranged in the base 1. A driving member for driving the grinding disc 26 to rotate is arranged between the lifting control mechanism and the grinding disc 26. The grinding disc 26 penetrates the punching groove 12 under the lifting of the lifting control mechanism, so that the grinding disc 26 can grind the burrs at the bottom of the punching hole of the special-shaped part.

[0031] The main function of the die base 10 is to accurately locate and place the shaped part by opening a groove that matches the shaped part inside; the main function of the punching groove 12 is to punch a hole on the surface of the shaped part by cooperating with the punching assembly; the main function of the grinding disc 26 is to grind and remove the burrs below the hole; the main function of the lifting control mechanism is to lower the grinding disc 26 into the base 1 during the punching process, and lift the grinding disc 26 to contact the bottom of the hole of the shaped part after the punching is completed, so as to grind the burrs. Overall, the present invention can perform precise punching operations on automotive parts, and can immediately grind the burrs on the edge of the hole after the punching is completed, thereby improving the finished product quality and processing efficiency of automotive parts.

[0032] A further optimized solution is that a connecting plate 15 is vertically slidably connected to the base 1, and a plurality of screw rods 29 are vertically rotatably connected to the base 1. The edge threads of the connecting plate 15 are threadedly sleeved on the plurality of screw rods 29, and one end of the plurality of screw rods 29 is respectively transmission-connected to a third motor 30, and a lifting control mechanism is arranged on the connecting plate 15.

[0033] According to a further optimization scheme, a plurality of ejector rods 13 are vertically fixedly connected to the top of the connecting plate 15 . The tops of the plurality of ejector rods 13 pass through the mold base 10 and are fixedly connected to the ejector blocks 11 . When the connecting plate 15 is in a low position, the ejector blocks 11 are flush with the inner bottom of the mold base 10 .

[0034] like Figure 1 and Figure 3 As shown, a gear set is arranged between the third motor 30 and the screw rod 29. When the punching process is completed, the third motor 30 rotates to drive the screw rod 29 to rotate through the gear set, and the connecting plate 15 is driven to rise through the threaded transmission between the screw rod 29 and the connecting plate 15, and then the ejector block 11 is driven to rise through the ejector rod 13, and the accessory is lifted from the die base 10, so that the grinding disc 26 is in contact with the bottom of the punched hole on the accessory and the final operator is convenient for taking the accessory.

[0035] The top block 11 can be lowered to be flush with the inner bottom of the mold base 10 by controlling the third motor 30 to rotate in the reverse direction.

[0036] A further optimized solution is that the lifting control mechanism includes a support frame 17 fixedly connected to the bottom of the connecting plate 15, a second hydraulic cylinder 16 is vertically fixedly connected inside the support frame 17, the top of the second hydraulic cylinder 16 passes through the connecting plate 15 and is fixedly connected to a connecting frame 18, and the connecting frame 18 is fixedly connected to the driving member.

[0037] like Figure 1 As shown, at least two groups of second hydraulic cylinders 16 are arranged in the support frame 17 to ensure that the connecting frame 18 will not rotate due to the reverse torque when the grinding plate 26 rotates.

[0038] As a further optimization scheme, a blanking hole 14 is provided on the top of the base 1 and is connected to the punching groove 12 on the die base 10 to facilitate the penetration of the grinding disc 26 .

[0039] A further optimized solution is that the driving member includes a fixed plate 23 fixedly connected to the top of the connecting frame 18, a first motor 22 is vertically fixedly connected in the fixed plate 23, a rotating plate 24 is arranged on the top of the fixed plate 23, the output shaft of the first motor 22 is fixedly connected to the edge of the rotating plate 24, a slide groove 28 is horizontally provided on the top of the rotating plate 24 along the radial direction of the rotating plate 24, a second motor 25 is slidably connected in the slide groove 28, a second spring 27 is abutted between the second motor 25 and the end of the slide groove 28 close to the edge of the rotating plate 24, and the output shaft of the second motor 25 is transmission-connected to the grinding disc 26.

[0040] like Figure 1 , Figure 2 and Figure 4 , Figure 5 As shown, when the second motor 25 is in a stationary state, the second spring 27 pushes the second motor 25 to the center position of the rotating plate 24. At this time, the edge of the grinding disc 26 is located on the inner side of the edge of the rotating plate 24, and the second hydraulic cylinder 16 can drive the fixed plate 23, the rotating plate 24 and the grinding disc 26 to smoothly penetrate the punching groove 12.

[0041] like Figure 4 As shown, when the fixed plate 23 is inside the mold base 10, the first motor 22 rotates, driving the rotating plate 24 to rotate eccentrically, and the second motor 25 moves toward the edge of the slide 28 under the action of centrifugal force. At this time, the second motor 25 is started to drive the grinding disc 26 to rotate. The grinding disc 26 can rotate along the edge of the hole while rotating on its own to grind off the bottom burrs.

[0042] After grinding is completed, the first motor 22 stops rotating. At this time, the second motor 25 is reset along the slide slot 28 to a position close to the center of the rotating plate 24 under the elastic force of the second spring 27, so as to facilitate the descending and recovery of the grinding disc 26.

[0043] After machining for a period of time, the grinding debris in the mold base 10 can be blown away by a high-pressure air gun.

[0044] According to a further optimization scheme, a blanking plate 21 is obliquely arranged in the base 1, the high end of the blanking plate 21 is arranged corresponding to the punching groove 12, and the low end of the blanking plate 21 is arranged corresponding to the storage box 19;

[0045] The side walls at both ends of the blanking plate 21 are slidably connected in the base 1 through horizontally arranged slideways 20 , and a sliding driving member is arranged between the blanking plate 21 and the thread rod 29 .

[0046] A further optimized solution is that the sliding drive component includes two sets of sprockets 32, one sprocket 32 ​​is fixedly mounted on the end of the screw rod 29, and the other sprocket 32 ​​rotates horizontally in the base 1, and a chain 33 is wound around the two sprockets 32, and one end of a connecting rod 31 is fixedly connected to the chain 33, and the other end of the connecting rod 31 is fixedly connected to the blanking plate 21.

[0047] like Figure 1 , Figure 4 and Figure 6 As shown, during the punching process, the waste punched out by the punching assembly can fall onto the blanking plate 21 through the punching groove 12 and the blanking hole 14 on the top of the base 1, and fall along the blanking plate 21 into the storage box 19. The storage box 19 is configured to be detachably connected to the base 1.

[0048] After punching is completed, the connecting plate 15 moves upward under the drive of the screw rod 29, and the screw rod 29 drives the sprocket 32 ​​to rotate, so that the chain 33 moves and drives the blanking plate 21 to move to the right through the connecting rod 31, so that the high end of the blanking plate 21 avoids the grinding disc 26 to avoid movement interference.

[0049] A further optimized solution is that the punching assembly includes a frame 2 fixedly connected to the top of the base 1, a sleeve 3 is fixedly connected to the top of the frame 2 vertically downward, a telescopic block 4 is slidably connected inside the sleeve 3, a first hydraulic cylinder 5 is transmission-connected between the telescopic block 4 and the sleeve 3, and a punch 6 is fixedly connected to the bottom of the telescopic block 4, and the punch 6 is adapted to the punching groove 12.

[0050] like Figure 1 As shown, during the punching process, the first hydraulic cylinder 5 is controlled to extend, so that the telescopic block 4 is lowered, and finally the punch 6 is extended into the punching groove 12 to punch the required hole in the fitting in the die base 10.

[0051] According to a further optimization scheme, a plurality of sleeves 7 are vertically fixedly connected to the bottom of the telescopic block 4, the plurality of sleeves 7 are arranged close to the punch 6, and a pressure block 9 is vertically slidably connected to the bottom of the plurality of sleeves 7, and a first spring 8 is abutted between the pressure block 9 and the sleeve 7.

[0052] like Figure 1 As shown, in order to prevent the accessory from warping at the edge of the punching process, during the descent of the telescopic block 4, the pressing block 9 first contacts the area around the position where the accessory needs to be holed, and as the telescopic block 4 descends, the pressing block 9 compresses the first spring 8, increasing the pressure of the pressing block 9 on the accessory, and then when the punch 6 punches the hole, warping can be effectively prevented.

[0053] The working process of this embodiment is as follows: the operator places the accessory in the die base 10, controls the first hydraulic cylinder 5 to extend, and makes the telescopic block 4 descend, so that a number of pressing blocks 9 first contact with the parts around the positions where holes need to be formed on the accessories, and presses the accessories between the die base 10 and the pressing blocks 9. As the telescopic block 4 continues to descend, the punch 6 punches a hole in the accessory, and the waste falls onto the blanking plate 21 through the punching groove 12 and the blanking hole 14 on the top of the base 1, and slides along the blanking plate 21 into the storage box 19.

[0054] After that, the telescopic block 4 rises to a certain height, and at the same time, the third motor 30 rotates, so that the connecting plate 15 moves up, driving the top block 11 to rise and lift the accessory from the die base 10 to the top of the accessory and contact the pressing block 9. After that, the second hydraulic cylinder 16 extends, so that the grinding disc 26 passes through the punching groove 12 and is located at the bottom of the accessory hole, and the first motor 22 and the second motor 25 are started, so that the grinding disc 26 rotates while rotating eccentrically around the output shaft of the first motor 22, and the burrs on the bottom edge of the hole are polished. After polishing, the grinding disc 26 is retracted and the telescopic block 4 is reset to the top. At this time, the accessory is separated from the die base 10 due to the action of the top block 11, which is convenient for taking the accessory.

[0055] After the accessory is taken, the third motor 30 rotates in the opposite direction to reset the position of the top block 11 to facilitate subsequent processing of the accessory.

[0056] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0057] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
