Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing, and in particular to a punching and drilling device for mechanical parts processing. Background Technology

[0002] A punching and drilling device for machining mechanical parts is a specialized piece of equipment that utilizes the shearing force of a die to efficiently machine holes in metal sheets or prefabricated parts. Its core consists of a pressure mechanism, precision dies, and a positioning system. During operation, the punch, driven by pressure, impacts the material at high speed, and the die, in conjunction with the punch, instantly shears the material to form a precise hole. Its advantages include high efficiency, high precision, and low batch cost, making it widely used in standardized hole machining in automotive parts, electronic chassis, and other fields. Safety protection devices are required to avoid operational risks.

[0003] Existing devices require multiple sets of bolts to loosen the upper and lower molds and remove them when changing molds for drilling. Then, multiple sets of bolts are used to replace the required upper and lower molds, which slows down the work progress and is very cumbersome and inconvenient. In addition, the waste material that falls off the parts during drilling often falls to the ground and needs to be cleaned up after the work is finished, resulting in a messy working environment and affecting work safety. Therefore, a stamping and drilling device for machining mechanical parts is proposed to solve the above problems. Utility Model Content

The bottom inner wall of the housing 1 is provided with a waste trough 45 for receiving stamping waste and guiding it into a collection frame 41. The size of the waste trough 45 is slightly larger than the size of the lower mold 34. A hydraulic cylinder 2 is fixedly connected to the inner wall of the housing 1. The hydraulic cylinder 2 is located directly above the sliding column 39. The internal size of the hydraulic cylinder 2 and the sliding sleeve 33 are adapted to each other. The hydraulic cylinder 2 drives the sliding column 39 to realize the stamping and drilling action by telescopically driving the sliding column 39. A quick-change mechanism 3 is provided on the inner wall of the housing 1. The quick-change mechanism 3 can quickly change the mold and improve work efficiency. A collection mechanism 4 is provided on the inner wall of the housing 1. The collection mechanism 4 can collect the waste generated after drilling.

[0019] Reference Figures 2-4 As shown, the quick-change mechanism 3 includes a rotating rod 31, which connects to a first turntable 32 and a second turntable 35, driving them to rotate synchronously to switch molds. The rotating rod 31 is rotatably connected to the inner wall of the outer casing 1. The outer wall of the rotating rod 31 is fixedly connected to the first turntable 32. The first turntable 32 is equipped with a sliding sleeve 33 to support the sliding column 39 to slide up and down. The inner wall of the first turntable 32 is fixedly connected to the sliding sleeve 33. Multiple sets of sliding sleeves 33 are arranged in a circular array and fixedly connected to the inner wall of the first turntable 32. A sliding track is provided for the sliding column 39 and a first spring 37 is installed thereon. The sliding column 39 is slidably connected to the inner wall of the sliding sleeve 33. The sliding column 39 can be connected to the hydraulic cylinder 2 and the upper mold 310 to transmit stamping power. A fixing block 38 is fixedly connected to the outer wall of the sliding column 39. The fixing block 38 can limit the stroke of the sliding column 39 and fix the position of the first spring 37. The sliding column 39 is elastically connected to the inner wall of the sliding sleeve 33 through the first spring 37. One end of the first spring 37 is fixedly connected to the inner wall of the sliding sleeve 33, and the other end of the first spring 37 is fixed. Connected to the outer wall of the fixed block 38, the first spring 37 can restore the stamped sliding column 39 to its original position. An upper die 310 is fixedly connected to the bottom outer wall of the sliding column 39. The upper die 310 cooperates with the lower die 34 to stamp and drill the parts. A second turntable 35 is fixedly connected to the outer wall of the rotating rod 31. The second turntable 35 is rotatably connected to the inner wall of the outer casing 1. The second turntable 35 is used to install the lower die 34 and can rotate to switch between different lower dies 34. A lower die 34 is fixedly connected to the top outer wall of the second turntable 35. The lower die 34 has several... The quantity and position are adapted to the sliding sleeve 33. The lower mold 34 cooperates with the upper mold 310 to realize the stamping and punching of the parts. The inner wall of the second turntable 35 is slidably connected to the fixing rod 36. The fixing rod 36 is snapped into the positioning groove 312 on the inner wall of the outer shell 1. The fixing rod 36 can fix the second turntable 35 to prevent rotation by snapping into the positioning groove 312. The fixing rod 36 is elastically connected to the inner wall of the second turntable 35 by the second spring 311. The second spring 311 makes the fixing rod 36 snap into the positioning groove 312 to prevent the fixing rod 36 from falling off accidentally.

[0020] Reference Figures 4-6 As shown, the collection mechanism 4 includes an inclined rod 43, which is slidably connected to the inner wall of the outer shell 1. The inclined rod 43 is engaged in the slot 46 on the inner wall of the collection frame 41. The inclined rod 43 fixes and limits the collection frame 41 through the slot 46. The inclined rod 43 is elastically connected to the inner wall of the outer shell 1 through a third spring 44. The third spring 44 makes the inclined rod 43 firmly fixed against the slot 46 on the inner wall of the collection frame 41. A connecting rod 42 is fixedly connected to the outer wall of the top of the inclined rod 43. The connecting rod 42 is linked to the inclined rod 43 to control the loading and unloading of the collection frame 41. The inner wall of the outer shell 1 is detachably connected to the collection frame 41. The inner wall of the collection frame 41 has a slot 46. The collection frame 41 is used to receive stamping waste for easy centralized cleaning of waste.

[0021] In use, the fixing rod 36 is first pulled out, and the second turntable 35 is rotated to drive the rotating rod 31 to rotate. When the rotating rod 31 rotates, it drives the first turntable 32 to rotate together. When the first turntable 32 rotates, it drives the sliding sleeve 33 to rotate. The second turntable 35 rotates to the desired mold position. The fixing rod 36 is then engaged in the positioning slot 312 on the inner wall of the outer shell 1 by the second spring 311 to fix the first turntable 32 and the second turntable 35, thus achieving rapid mold change. At this time, the upper mold 310 of the required specifications moves to the bottom of the hydraulic cylinder 2. After the hydraulic cylinder 2 is started, the bottom end of the hydraulic cylinder 2 moves down to push the sliding column 39 downward, driving the upper mold 310 to press downward.

[0022] Waste generated during the stamping and drilling process falls into the collection frame 41 through the waste trough 45 at the bottom of the outer casing 1. When the collection frame 41 is full, first pull the connecting rod 42 upward to disengage the inclined rod 43 from the inner wall slot 46 of the collection frame 41. Take out the full collection frame 41. When the cleaned collection frame 41 is placed into the inner wall of the outer casing 1, the inclined rod 43 is lifted by the contact and compression of the inclined surface at the bottom of the collection frame 41. After being placed at the bottom, the inclined rod 43 is engaged and fixed with the slot 46 on the collection frame 41, thus completing the replacement of the collection frame 41.
