Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to automotive duct cutting equipment with integrated drilling function. Background Technology

[0002] Automotive air conditioning ducts are blow-molded products. After the product is demolded, excess waste material needs to be removed. Traditional processes use manual removal, which is inefficient, labor-intensive, and costly. Moreover, manual cutting is tedious and cannot guarantee safety.

[0003] Existing patent document CN217414850U discloses a cutting fixture for automotive air conditioning ducts, which includes two sets of cutting devices I for cutting waste material from the air vents at both ends of the air conditioning duct; and a set of cutting devices II for cutting waste material from the air vents in the middle of the air conditioning duct. Additionally, it includes fixing seats I, II, and III for positioning the middle, middle section, and both ends of the air conditioning duct, respectively. Furthermore, it includes a front clamp and a rear clamp for clamping the middle section and the middle air vent of the air conditioning duct, respectively, to ensure the stability of the cutting process.

[0004] This utility model relates to a blow-molded duct assembly. After molding, the duct assembly is a sealed tube. It requires cutting the head and tail of the duct using a cutting tool to open both ends of the duct. Simultaneously, holes need to be drilled in the duct for installation and fixation. Currently, cutting and drilling are performed using different equipment, resulting in low work efficiency and large hole position errors.

[0005] The above background information is provided only to aid in understanding the concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Utility Model Content

[0006] The main purpose of this utility model is to propose a multi-functional automotive duct cutting device that is simple in structure, highly efficient, and capable of cutting and drilling operations.

[0007] Therefore, this utility model proposes an automotive duct cutting device with integrated drilling function.

[0008] Preferably, the present invention may also have the following technical features:

[0009] An automotive duct cutting device with integrated drilling function includes a frame, a head cutting assembly, a tail cutting assembly, and a head drilling mechanism mounted on the frame, and also includes a blade drilling mechanism. The head cutting assembly is located between the head drilling mechanism and the blade drilling mechanism, and the tail cutting assembly is located to the right of the blade drilling mechanism.

[0010] The head cutting assembly is provided with a first positioning cavity for fixing the air duct, and the first positioning cavity has at least one longitudinal first clearance hole; the head punching mechanism includes a first longitudinal cylinder, a first connecting plate, and a first punching shaft. The first longitudinal cylinder is mounted on the frame through the first connecting plate, and its telescopic rod end is connected to the first punching shaft; the first punching shaft and the first clearance hole are coaxial.

[0011] Furthermore, the head cutting assembly includes a first cutting assembly, a lower head mold, an upper head mold, and a first driving assembly. The lower head mold is fixed on the frame, and the upper head mold is located directly above the lower head mold. It moves closer to or further away from the lower head mold via the first driving assembly. The lower head mold has a lower cavity for positioning the air duct head on its left side and the first cutting assembly on its right side. The lower cavity has a first clearance hole.

[0012] Furthermore, the first cutting assembly includes a first cutter, a first cutter groove, and a second driving assembly. The two first cutter grooves are respectively fixed on the upper and lower sides of the lower head mold. The first cutter is installed in the first cutter groove and is driven by the second driving assembly to reciprocate along the guide stroke of the first cutter groove.

[0013] Furthermore, the first cutting groove installed on the upper side of the lower head mold includes a fixed cutting groove and a movable cutting groove. The fixed cutting groove is installed on the right side of the lower head mold, and the movable cutting groove is installed on the upper head mold. When the upper head mold and the lower head mold are fitted together, the first cutting groove is formed.

[0014] Furthermore, the head cutting assembly also includes a first guide device.

[0015] Furthermore, the right side of the lower head mold is also provided with a first clearance groove.

[0016] Furthermore, it also includes a first positioning block, which is mounted on the first connecting plate and has a first guide hole corresponding to the position of the first clearance hole; the first drilling shaft and the first guide hole are slidably engaged.

[0017] Furthermore, the tail cutting assembly includes a lower tail mold, an upper tail mold, a cutting mechanism, and a third driving assembly. The upper tail mold is mounted on the third driving assembly, and the upper tail mold is driven by the first driving assembly to fit or separate from the lower tail mold. When the upper tail mold and the lower tail mold fit together, a second positioning cavity is formed at the tail of the positioning duct.

[0018] Furthermore, it also includes a first baffle, which is fixed to the frame and located on the right side of the lower tail mold.

[0019] Furthermore, the first baffle is tilted, with its left side higher than its right side.

[0020] The beneficial effects of this utility model compared with the prior art include: during operation, the lower and upper head molds are used to fix the duct in place, then the first cutting assembly is driven to cut the duct head, and then the first punching shaft extends and presses the duct head to a predetermined position until the duct head is pierced, with the first punching shaft extending into the first clearance hole. This application achieves both cutting and punching functions by improving the mechanism of the head cutting assembly and adding a punching mechanism, simplifying production tools. Cutting and punching operations can be completed in one device, eliminating the need to move and repeatedly position the duct, thus significantly improving work efficiency.

[0027] The present invention will now be described in further detail with reference to specific embodiments and the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0028] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein the same reference numerals denote the same parts unless otherwise specifically stated.

[0029] like Figures 1-5 The illustrated automotive duct cutting device with integrated drilling function includes a frame 1, and a head cutting assembly 5, a tail cutting assembly 2, a head drilling mechanism, and a blade drilling mechanism mounted on the frame 1. The head cutting assembly 5 is located between the head drilling mechanism and the blade drilling mechanism, and the tail cutting assembly 2 is located to the right of the blade drilling mechanism.

[0030] The head cutting assembly 5 includes a first cutting assembly, a lower head mold 54, an upper head mold 56, and a first driving assembly 58. The lower head mold 54 is fixed on the frame 1. The upper head mold 56 is located directly above the lower head mold 54. It moves closer to or further away from the lower head mold 54 via the first driving assembly 58. When the upper head mold 56 and the lower head mold 54 are in contact, a first positioning cavity is formed for positioning the duct head 101, thereby locking the duct head 101 in place. The lower head mold 54 has a lower cavity 55 for positioning the duct head 101 on its left side and the first cutting assembly on its right side. The lower cavity 55 has at least one longitudinal first clearance hole 59. The head punching mechanism includes a first longitudinal cylinder 64, a first connecting plate 63, and a first punching shaft 62. The first longitudinal cylinder 64 is mounted on the frame 1 via the first connecting plate 63, and its telescopic rod end is connected to the first punching shaft 62. The first drilling shaft 62 and the first clearance hole 59 are coaxial. The first drilling shaft 62 is pushed into or out of the first clearance hole 59 by the extension and retraction displacement of the first longitudinal cylinder 64. Figure 6 During operation, the lower die 54 and upper die 56 of the head are used to fix the duct in place. Then, the first cutting assembly is driven to cut the duct head 101. The first punching shaft 62 then extends and presses the duct head 101 to a predetermined position until it is pierced through. The first punching shaft 62 extends into the first clearance hole 59. Preferably, the first clearance hole 59 is a through hole, thus preventing the edge material of the duct head 101 punched out by the first punching shaft 62 from accumulating inside the first clearance hole 59. Specifically, the first driving assembly 58 is a first vertical cylinder.

[0031] Continue to refer to Figure 2 The first cutting assembly includes a first cutter 52, a first cutting groove 53, and a second driving assembly 51. The two first cutting grooves 53 are respectively fixed to the upper and lower sides of the lower head mold 54. The first cutter 52 is installed within the first cutting groove 53 and is driven by the second driving assembly 51 to reciprocate along the guide stroke of the first cutting groove 53, moving towards or away from the lower cavity 55. Preferably, the second driving assembly 51 is a first transverse cylinder.

[0032] The head cutting assembly also includes a first guide device 57, which improves the stability and reliability of the head upper mold 56 driven by the first drive device.

[0033] A further improvement to the above technical solution is that the first cutting groove 53 installed on the upper side of the lower head mold 54 includes a fixed cutting groove and a movable cutting groove 531. The fixed cutting groove is installed on the right side of the lower head mold 54, and the movable cutting groove 531 is installed on the upper head mold 56. When the upper head mold 56 and the lower head mold 54 are fitted together, the first cutting groove 53 is formed. By dividing the first cutting groove 53, interference between the first cutting groove 53 and the fitting of the upper head mold 56 and the lower head mold 54 can be avoided.

[0034] Combination Figure 3 In the above, the right side of the head lower mold 54 is also provided with a first clearance groove 541 for the movement of the telescopic rod of the first transverse cylinder. The right side of the first cutter 52 is connected to the end of the telescopic rod of the first transverse cylinder by bolts, which facilitates the rotation of the bolts and makes disassembly and assembly convenient.

[0035] Re-reference Figure 1 To improve the working accuracy of the first drilling shaft 62, a first positioning block 61 is also included. The first positioning block 61 is mounted on the first connecting plate 63 and has a first guide hole corresponding to the position of the first clearance hole 59. The first drilling shaft 62 and the first guide hole are in sliding fit. The first guide hole strengthens the rigidity of the first drilling shaft 62 and reduces the risk of deformation of the first drilling shaft 62.

[0036] Reference Figure 4 The tail cutting assembly 2 includes a lower tail mold 24, an upper tail mold 23, a cutting mechanism, and a third drive assembly 21. The upper tail mold 23 is mounted on the third drive assembly 21, and the third drive assembly 21 drives the upper tail mold 23 to fit or separate from the lower tail mold 24. When the upper tail mold 23 and the lower tail mold 24 fit together, a second positioning cavity is formed for the positioning duct tail 102. The cutting mechanism is connected to the fourth drive assembly 27, and the fourth drive assembly 27 pushes the cutting mechanism to cut the duct tail 102. Preferably, the third drive assembly, the cutting mechanism, and the fourth drive assembly 27 are arranged vertically.

[0037] The structure of the cutting mechanism is similar to that of the first cutting assembly. It includes a cutter 25, a second cutting groove 24, and a fourth driving assembly 27. The fourth driving assembly drives the cutter 25 to move within the guide stroke of the second cutting groove 24 to move closer to or further away from the second positioning cavity. It also includes a second guiding device 22, which improves the reliability and stability of the movement of the tail upper mold 23.

[0038] Furthermore, it also includes a first baffle 7, which is fixed on the frame 1 and located on the right side of the tail lower mold 28. After the tail cutting group 2 cuts the tail of the air duct, the cut part falls onto the first baffle 7 and then into the recycling basket on the right side of the frame 1. Preferably, the first baffle 7 is inclined, with its left side higher than its right side.

[0039] Refer to Figure 5 The blade drilling mechanism includes a second transverse cylinder 45, a second positioning block 44, a first guide rail assembly 3, a second longitudinal cylinder 43, a second drilling shaft 41, and a second connecting plate 42. The second connecting plate 42 is arranged longitudinally and slidably mounted on the frame 1 via the first guide rail assembly 3. The second positioning block 44 is mounted at its front end, and the second longitudinal cylinder 43 is mounted at its rear end. The telescopic rod end of the second transverse cylinder 45 is connected to the left side of the second connecting plate 42. The telescopic movement of the second transverse cylinder 45 pushes the second connecting plate 42 to move along the guide stroke of the first guide rail assembly 3, i.e., it moves along the left and right direction of the frame 1. The right side of the second positioning block 44 has an opening 49 in a U-shape, with a guide hole 47 penetrating both sides of the opening 49 in the middle. The rear end of the second drilling shaft 41 is fixed to the telescopic rod end of the second longitudinal cylinder 43, and the front end extends into the guide hole 47. Under normal conditions, the second longitudinal cylinder 43 retracts into position, and the front end of the second punching shaft 41 exits the opening 49. According to the model of the duct 100, the second transverse cylinder 45 extends, pushing the second connecting plate 42 to the predetermined position. At this time, the middle fixed blade 103 of the duct 100 is located in the opening 49 of the second positioning block 44 and is close to the side of the second positioning block 44 away from the second longitudinal cylinder 43. The second longitudinal cylinder 43 extends, the second punching shaft 41 enters the space of the opening 49, and then presses the fixed blade 103 into the inside of the opening 49 until the second punching shaft 41 passes through the guide hole away from the side of the second longitudinal cylinder 43.

[0040] Preferably, the system further includes a support frame 46, on which the first guide rail assembly 3 is mounted. An L-shaped support rod 48 is also provided on the front side of the support frame 46 to support the middle portion of the duct 100. The L-shaped support rod 48 includes a vertical rod and a longitudinal rod. The vertical rod is vertically positioned and has an elongated hole 481 along its length. The end of the longitudinal rod extends towards the head cutting assembly. The L-shaped support rod 48 is fixed to the support frame 46 with bolts, and the fixed position of the L-shaped support rod 48 is adjusted according to the duct model.
