Description

Technical Field

[0001] The present application relates to the technical field of punching equipment, and in particular to a punching and drilling device for the production of automobile parts. Background Art

[0002] In modern industrial production, punching is one of the important forms of hole processing. Compared with drilling, punching can process various hole types on different materials to meet different usage requirements, and the processing efficiency is higher. Especially in the field of mechanical processing, punching greatly improves the production and processing efficiency of parts and components.

[0003] During the punching process, the gap between the upper and lower dies has an important influence on the quality of hole forming. If the gap is too large or too small, it will have an adverse effect on the blanking parts. If the gap is too large, the blanking parts will produce large burrs and reduce dimensional accuracy; if the gap is too small, the size of the blanking parts will change due to the elastic recovery of the material, which will lead to unstable dimensional accuracy.

[0004] Among them, the gap between the upper and lower dies is generally determined according to the thickness of the blank. However, in the existing punching process, the gap between the upper and lower dies is greatly interfered by human factors when adjusting the gap, and the selection and adjustment accuracy of the gap size are low, which seriously affects the punching quality of the blank. In addition, multiple debugging is required before batch production, which is inefficient and easily causes material waste, and has poor stability and reliability.

[0005] Therefore, there is an urgent need for a punching and forming device to solve the defects existing in the above-mentioned existing punching and forming devices during actual use. Summary of the invention

[0006] The present application proposes a stamping and drilling device for the production and manufacturing of automobile parts, which has a lower die that can automatically select a gap size that is suitable according to the thickness of the punched part, so that it has the advantages of good quality, precision and high efficiency in punching the punched part. It is used to solve the problem that in the existing punching process, the gap between the upper and lower dies is greatly interfered by human factors when adjusting the gap, and the selection and adjustment accuracy of the gap size are low, which seriously affects the punching quality of the punched part, and multiple debugging is required before batch processing and production, which is inefficient and easily causes material waste.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a stamping and drilling device for the production and manufacturing of automobile parts, comprising a transmission shaft fixedly mounted on a hydraulic power device at the top and a lower die assembly fixedly mounted on an operating table by bolts for carrying the blanking parts, a punch being fixedly connected to the bottom of the inner cavity of the transmission shaft by a pin shaft, and then the hydraulic power device can be used to drive the transmission shaft and the punch thereon to move up and down, and perform punching operations on the blanking parts located on the lower die assembly, a group of linkage components are respectively provided on both sides of the outer surface of the transmission shaft, the linkage component comprises a frame fixedly mounted on the bottom of the outer surface of the transmission shaft, a linkage rod is provided on one side of the bottom end of the frame, and an elastic member is provided in the middle of the outer surface of the linkage rod, the linkage rod is transmission-connected to the frame through the elastic member, and then, initially, under the elastic force of the elastic member, the linkage rod is positioned upward, and a feedback rod for detecting and feeding back the thickness of the blanking parts is fixedly mounted on the top of the linkage rod.

[0008] Furthermore, the lower mold assembly includes a bracket fixedly mounted on an operating table, and a slider is movably connected to the top of the bracket, and a plurality of groups of lower molds with different inner diameters are arranged inside the slider. The slider is transmission-connected to a driving mechanism fixedly mounted on one side of the end of the bracket, and the slider can be driven by the driving mechanism to move linearly along the trajectory of the bracket, and a feedback electrical connection is formed between the driving mechanism and the feedback rod through a control system, and the displacement of the slider driven by the driving mechanism is determined through feedback from the feedback rod.

[0009] Furthermore, a first induction ring is fixedly sleeved on the top of the outer surface of the feedback rod, and the first induction ring is in contact with a second induction ring fixedly sleeved on the inner wall of the frame, and feedback is provided at the time node when the first induction ring and the second induction ring undergo relative displacement, and the driving mechanism is triggered to drive the slider to move linearly, and the driving mechanism is no longer triggered when the relative displacement occurs subsequently.

[0010] Furthermore, the lower die is clamped to the inside of the slider by bolts, so that lower dies of different specifications and models can be flexibly replaced according to actual usage, and the inner diameter of the lower die gradually increases from left to right, and initially, the leftmost lower die is located directly below the punch.

[0011] Furthermore, the speed at which the drive shaft drives the punch and the linkage assembly to move downward is determined, and the thickness of the blank is determined according to the time node at which the first induction ring and the second induction ring generate relative displacement, thereby regulating the drive mechanism to drive the slider to generate different degrees of linear displacement:

[0012] The earlier the time node arrives, the thicker the blank is, which forces the driving mechanism to drive the slider to the left to produce a larger displacement to move the lower die with a larger inner diameter to the bottom of the punch.

[0013] The later the time node arrives, the smaller the thickness of the blank is, which forces the driving mechanism to drive the slider to the left to produce a smaller displacement in order to move the lower die with a smaller inner diameter to directly under the punch.

[0014] Furthermore, a pressure block made of rubber material is fixedly installed at the bottom end of the linkage rod, and when the linkage rod moves downward along with the transmission shaft, the pressure block contacts the outer surface of the blanking part to prevent the linkage rod from scratching the surface of the blanking part during the process of pressing the blanking part.

[0015] Furthermore, initially, the height of the bottom end of the punch is higher than the height of the bottom end of the pressure block, thereby ensuring that when the transmission shaft drives the punch and the linkage assembly downward, the bottom end of the pressure block first contacts the surface of the blank, and causes a relative displacement between the first induction ring and the second induction ring.

[0016] The beneficial effects of the present invention are as follows:

[0017] The present application provides a stamping and drilling device for the production and manufacturing of automobile parts. For the setting of the linkage component, the time node when the first induction ring and the second induction ring produce relative displacement can be used to determine the thickness of the blank, and the lower die with different inner diameters can be moved to the position directly below the punch according to the arrival of the time node, and then the appropriate punching gap can be automatically selected according to the thickness of the blank, so that the punching equipment has better quality, precision and higher efficiency for punching the blank.

[0026] like Figure 1 , Figure 2 As shown, a punching and drilling device for manufacturing automobile parts comprises a transmission shaft 1 fixedly mounted on a hydraulic power device at the top and a lower die assembly 3 fixedly mounted on an operating table by bolts for carrying a blanking piece 4. A punch 2 is fixedly connected to the bottom of the inner cavity of the transmission shaft 1 by a pin shaft, and the hydraulic power device can be used to drive the transmission shaft 1 and the punch 2 thereon to move up and down, and punch the blanking piece 4 located on the lower die assembly 3. A group of linkage assemblies 5 are respectively provided on both sides of the outer surface of the transmission shaft 1, as shown in FIG. Figure 3 As shown, the linkage assembly 5 includes a frame 6 fixedly mounted on the bottom of the outer surface of the transmission shaft 1, a linkage rod 7 is provided on one side of the bottom end of the frame 6, and an elastic member 8 is provided in the middle of the outer surface of the linkage rod 7, the linkage rod 7 is transmission-connected with the frame 6 via the elastic member 8, and then initially, under the elastic force of the elastic member 8, the linkage rod 7 is positioned upward, and a feedback rod 9 for detecting and feeding back the thickness of the blank 4 is fixedly mounted on the top of the linkage rod 7.

[0027] like Figure 5 As shown, in the present technical solution, the lower mold assembly 3 includes a bracket 13 fixedly mounted on an operating table, and a slider 14 is movably connected to the top of the bracket 13, and a plurality of groups of lower molds 15 with different inner diameters are arranged inside the slider 14. The slider 14 is transmission-connected to a driving mechanism 16 fixedly mounted on one side of the end of the bracket 13, and the slider 14 can be driven by the driving mechanism 16 to move linearly along the trajectory of the bracket 13, and a feedback electrical connection is formed between the driving mechanism 16 and the feedback rod 9 through a control system, and the displacement of the slider 14 driven by the driving mechanism 16 is determined through the feedback of the feedback rod 9.

[0028] like Figure 3 , Figure 4As shown, in the present technical solution, a first induction ring 11 is fixedly sleeved on the top of the outer surface of the feedback rod 9, and the first induction ring 11 is in contact with a second induction ring 12 fixedly sleeved on the inner wall of the frame 6, and feedback is provided at the time point when the first induction ring 11 and the second induction ring 12 are relatively displaced, and the driving mechanism 16 is triggered to drive the slider 14 to move linearly, and the driving mechanism 16 is no longer triggered when the relative displacement is subsequently generated.

[0029] like Figure 5 As shown, in the present technical solution, the lower die 15 is clamped inside the slider 14 by bolts, so that the lower die 15 of different specifications and models can be flexibly replaced according to actual usage, and the inner diameter of the lower die 15 gradually increases from left to right, and initially, the leftmost lower die 15 is located directly below the punch 2.

[0030] In the present technical solution, the speed at which the drive shaft 1 drives the punch 2 and the linkage assembly 5 to move downward is determined, and the thickness of the blank 4 is determined according to the time node at which the first induction ring 11 and the second induction ring 12 generate relative displacement, and then the driving mechanism 16 is adjusted to drive the slider 14 to generate different degrees of linear displacement:

[0031] The earlier the time node arrives, the thicker the blank 4 is, which forces the driving mechanism 16 to drive the slider 14 to move to the left with a larger displacement to move the lower die 15 with a larger inner diameter to the position directly below the punch 2;

[0032] The later the time node arrives, the smaller the thickness of the blank 4 is, which forces the driving mechanism 16 to drive the slider 14 to produce a smaller displacement to the left to move the lower die 15 with a smaller inner diameter to be directly below the punch 2.
