Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to an automotive roof edge cutting device. Background Technology

[0002] The car roof is an important part of the car interior. Located at the top of the car, it enhances the overall structural strength of the vehicle body and can accommodate the sunroof structure. After the metal roof is stamped, there are scraps at the edges of the mold. Therefore, it is necessary to use a cutting device to cut and shape the scraps at the edges to keep the dimensions of the metal roof in line with requirements. Existing cutting devices usually use staggered cutting tools.

[0003] CN221022303U discloses a device for cutting excess material after hot pressing of an automotive headliner. The device includes an upper module, a die-cutting seat below the upper module, and a cutter seat on the side of the outer wall of the die-cutting seat. A lower die, which cooperates with the upper module to hot press the headliner, is distributed below the upper module. A screw is connected to the top side of the cutter seat, with one end of the screw connected to the side of the die-cutting seat near the cutter seat. Fixing components for locking the screw are symmetrically arranged at the insertion point of the screw and the die-cutting seat. An upper cutter is provided at the lower end of the cutter seat, and a lower cutter, which cooperates with the upper cutter, is provided on the lower die. This invention utilizes a combination of a compression spring and a screw to fix the screw in a movable hole. When replacing the blade, the screw can be pulled out directly for replacement. This design avoids directly using multiple screws to fix the blade, and the screw-pull-out design reduces the time required for blade replacement by maintenance personnel.

[0004] While the existing technology CN221022303U has many advantages in use, it still has the following problems: its cooling of the cutter is not perfect. When the cutter reciprocates and cuts the metal part, the friction between the metal part and the cutter generates heat. The accumulated high temperature will affect the structural strength of the cutter and affect its service life. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a car roof edge cutting device.

[0006] The technical solution adopted by this utility model to solve its technical problem is an edge cutting device for automobile roof, including an upper mold base, a support base, a guide rod, and a fixed base. A lower mold base is provided on the lower outer wall of the upper mold base. Support bases are welded on both outer walls of the upper mold base. A liquid inlet pipe is threaded to the lower end of one outer wall of the support base. A fixed base is screwed to the outer side of the support base. Assembly holes are opened on both outer walls of the fixed base. A guide rod is movably installed inside the support base. A piston plate is screwed to the lower outer wall of the guide rod.

[0007] By adopting the above technical solution, the metal canopy is clamped and fixed between the upper and lower mold bases, maintaining the positional stability of the metal canopy edge during the cutting process and ensuring the cutting effect of the metal canopy. When the support base and guide rod move with the upper mold base, they will drive the guide rod and piston plate to move vertically. Thus, during the cutting of the metal canopy, coolant can be drawn from the inner cavity of the support base through the liquid inlet pipe, which can achieve cooling of the support base, fixed base and upper cutter, ensuring the temperature of the upper cutter, avoiding the temperature from affecting the structural strength of the upper cutter and ensuring the service life of the upper cutter.

[0008] Specifically, a connecting seat is installed on the upper outer wall of the upper mold base, and assembly holes are equally spaced and parallel on both outer walls of the lower mold base.

[0009] By adopting the above technical solution, the upper mold base can be connected to the matching hydraulic equipment through the connecting seat, so that the hydraulic equipment can drive the upper mold base to reciprocate vertically, ensuring the smooth opening and closing between the upper mold base and the lower mold base. The operator can fix the position by bolting through the assembly hole to ensure the stability of the lower mold base position.

[0010] Specifically, a drain pipe is threadedly connected to the outer wall of the support base on the side opposite to the inlet pipe. Both the inlet pipe and the drain pipe are connected to the inside of the support base. A one-way valve is threadedly connected to the outer wall of both the inlet pipe and the drain pipe. The inlet pipe and the drain pipe are located inside the assembly hole.

[0011] By adopting the above technical solution, the inlet pipe, the inner cavity of the support seat, and the outlet pipe form a circulation pipeline. When the piston plate is driven to move upward on the inner wall of the support seat, the inner cavity of the support seat is in a negative pressure state, so that coolant can be drawn from the inner cavity of the support seat through the inlet pipe. After the piston plate is pushed back to its original position by the return spring, the piston plate can push the coolant in the inner cavity of the support seat to be discharged through the outlet pipe. Moreover, the one-way valve ensures that the flow trajectory of the coolant is controlled, and the smooth flow of coolant in the support seat can be precisely controlled, avoiding the use of a power structure to drive the coolant and avoiding increasing the energy consumption of the equipment.

[0012] Specifically, a cover plate is screwed to the lower outer wall of the support base, and a sealing gasket is glued and fixed to the cover plate facing the outer wall of the support base. The upper surface of the sealing gasket is in contact with the lower surface of the support base.

[0013] By adopting the above technical solution, the cover plate and sealing gasket can provide reliable sealing for the inner cavity of the support seat, ensure the presence and sealing of the coolant in the inner cavity of the support seat, ensure the flow stability of the coolant, and allow for the disassembly and maintenance of the piston plate and guide rod by removing the cover plate.

[0014] Specifically, the upper cutter is screwed to the lower outer wall of the fixed base, and the lower cutter is screwed to the outer walls on both sides of the lower mold base. The upper cutter and the lower cutter are staggered.

[0015] By adopting the above technical solution, the upper and lower cutters can be staggered as the upper mold base moves, thereby enabling the cutting of the ceiling edge and ensuring cutting effect and efficiency.

[0016] Specifically, a sealing ring is bonded and fixed to the outer wall of the piston plate, and the sealing ring is in contact with the inner wall of the support seat. A return spring is sleeved on the outer side of the guide rod, and the two ends of the return spring are in contact with the upper end of the inner wall of the support seat and the upper outer wall of the piston plate, respectively. The piston plate is elastically connected to the upper end of the inner wall of the support seat through the return spring.

[0017] By adopting the above technical solution, the sealing ring can ensure the sealing between the piston plate and the support seat. Thus, when the piston plate moves vertically in the inner cavity of the support seat, it can draw or push out the coolant to achieve the circulation of the coolant. The return spring can be compressed and stored when the guide rod carries the piston plate to move upward. After the limit plate is removed from the drive rod, the return spring releases its elastic force, which can push the piston plate to move downward and reset, ensuring that the coolant can circulate.

[0018] Specifically, the guide rod protrudes from the end of the support base and is fitted with a limiting plate. The limiting plate is located at the upper end of the support base. Both outer walls of the lower mold base are threaded with drive rods, and the upper end face of the drive rod is in contact with the lower end face of the limiting plate.

[0019] By adopting the above technical solution, when the upper mold base moves down to the lower mold base, the drive rod will drive the limiting plate, causing the guide rod to be pushed out inside the support base, thereby driving the piston plate to move inside the support base. The limiting plate can limit the movement distance of the guide rod, ensuring that the movement distance of the piston plate inside the support base is controlled.

[0020] The beneficial effects of this utility model are:

[0021] The automotive roof edge cutting device of this utility model draws coolant from the inner cavity of the support seat through the liquid inlet pipe, which can cool the support seat, the fixed seat and the upper cutter, and ensure the temperature of the upper cutter, so as to avoid the temperature affecting the structural strength of the upper cutter and ensure the service life of the upper cutter.

[0022] The automotive roof edge cutting device described in this utility model can precisely control the smooth flow of coolant in the support base, avoiding the need to use a power structure to drive the coolant and thus avoiding increased equipment energy consumption. Attached Figure Description

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the automotive roof edge cutting device of this utility model includes an upper mold base 1, a support base 2, a guide rod 3, and a fixed base 4. A lower mold base 11 is provided on the lower outer wall of the upper mold base 1. Support bases 2 are welded to both outer walls of the upper mold base 1. A liquid inlet pipe 21 is threaded to the lower end of one outer wall of the support base 2. A fixed base 4 is screwed to the outer side of the support base 2. Assembly holes 41 are opened on both outer walls of the fixed base 4. The guide rod 3 is movably installed inside the support base 2. A piston plate 31 is screwed to the lower outer wall of the guide rod 3.

[0033] During use, the metal canopy is clamped and fixed between the upper mold base 1 and the lower mold base 11 to maintain the positional stability of the metal canopy edge during the cutting process and ensure the cutting effect of the metal canopy. When the support base 2 and the guide rod 3 move with the upper mold base 1, they will drive the guide rod 3 and the piston plate 31 to move vertically. Thus, during the cutting of the metal canopy, coolant can be drawn into the inner cavity of the support base 2 through the liquid inlet pipe 21, which can achieve cooling of the support base 2, the fixed base 4 and the upper cutter 42, and ensure the temperature of the upper cutter 42, so as to avoid the temperature affecting the structural strength of the upper cutter 42 and ensure the service life of the upper cutter 42.

[0034] To maintain the usage location, for example, such as Figure 1 As shown, a connecting seat 13 is installed on the upper outer wall of the upper mold base 1, and assembly holes are provided at equal intervals and parallel distribution on both sides of the lower mold base 11.

[0035] In use, the upper mold base 1 can be connected to the matching hydraulic equipment through the connecting seat 13, so that the hydraulic equipment can drive the upper mold base 1 to reciprocate vertically, ensuring the smooth opening and closing between the upper mold base 1 and the lower mold base 11. The operator can fix the position by bolting through the assembly hole to ensure the stability of the position of the lower mold base 11.

[0036] For example, to allow liquid to enter or exit, such as... Figure 4 As shown, a drain pipe 22 is threadedly connected to the outer wall of the support base 2 on the side opposite to the inlet pipe 21. Both the inlet pipe 21 and the drain pipe 22 are connected to the inside of the support base 2. One-way valves 23 are threadedly connected to the outer walls of both the inlet pipe 21 and the drain pipe 22. The inlet pipe 21 and the drain pipe 22 are located inside the assembly hole 41.

[0037] During use, the inlet pipe 21, the inner cavity of the support seat 2, and the outlet pipe 22 form a circulation pipeline. When the piston plate 31 is driven to move upward on the inner wall of the support seat 2, the inner cavity of the support seat 2 is in a negative pressure state, so that coolant can be drawn from the inner cavity of the support seat 2 through the inlet pipe 21. After the piston plate 31 is pushed back to its original position by the return spring 33, the piston plate 31 can push the coolant in the inner cavity of the support seat 2 to be discharged through the outlet pipe 22. The one-way valve 23 ensures that the flow trajectory of the coolant is controlled, and the smooth flow of the coolant in the support seat 2 can be precisely controlled, avoiding the need to use a power structure to drive the coolant and avoiding increasing the energy consumption of the equipment.

[0038] To maintain a tight seal, for example, such as Figure 4 As shown, a cover plate 24 is screwed to the lower outer wall of the support base 2. A sealing gasket 25 is glued and fixed to the cover plate 24 facing the outer wall of the support base 2. The upper surface of the sealing gasket 25 is in contact with the lower surface of the support base 2.

[0039] During use, the cover plate 24 and the sealing gasket 25 can provide reliable sealing for the inner cavity of the support seat 2, ensuring the presence and sealing of the coolant in the inner cavity of the support seat 2, ensuring the flow stability of the coolant, and the piston plate 31 and guide rod 3 can be disassembled and maintained by removing the cover plate 24.

[0040] For cutting, exemplified, such as Figure 3 As shown, the upper cutter 42 is screwed to the lower outer wall of the fixed base 4, and the lower cutter 12 is screwed to both outer walls of the lower mold base 11. The upper cutter 42 and the lower cutter 12 are staggered.

[0041] When in use, the upper cutter 42 and the lower cutter 12 can be staggered according to the movement of the upper mold base 1, thereby achieving the cutting of the edge of the ceiling and ensuring the cutting effect and cutting efficiency.

[0042] To drive a reset, for example, such as Figure 6 As shown, a sealing ring is bonded and fixed to the outer wall of the piston plate 31. The sealing ring is in contact with the inner wall of the support seat 2. A return spring 33 is sleeved on the outer side of the guide rod 3. The two ends of the return spring 33 are in contact with the upper end of the inner wall of the support seat 2 and the upper end of the outer wall of the piston plate 31, respectively. The piston plate 31 is elastically connected to the upper end of the inner wall of the support seat 2 through the return spring 33.

[0043] During use, the sealing ring ensures the sealing between the piston plate 31 and the support seat 2, so that when the piston plate 31 moves vertically in the inner cavity of the support seat 2, it can draw or push out the coolant to achieve the circulation of the coolant. The return spring 33 can be compressed and stored when the guide rod 3 carries the piston plate 31 upward. After the limit plate 32 is released from the restriction of the drive rod 14, the return spring 33 releases its elastic force, which can push the piston plate 31 downward to reset, ensuring that the coolant can circulate.

[0044] To drive movement, for example, such as Figure 1 As shown, the guide rod 3 protrudes from the end of the support base 2 and is fitted with a limiting plate 32. The limiting plate 32 is located at the upper end of the support base 2. Both sides of the outer wall of the lower mold base 11 are threaded with drive rods 14, and the upper end face of the drive rod 14 is in contact with the lower end face of the limiting plate 32.

[0045] When the upper mold base 1 moves down to the lower mold base 11 during use, the drive rod 14 drives the limiting plate 32, causing the guide rod 3 to be pushed out inside the support base 2, thereby driving the piston plate 31 to move inside the support base 2. The limiting plate 32 can limit the movement distance of the guide rod 3, ensuring that the movement distance of the piston plate 31 inside the support base 2 is controlled.

[0046] When using this utility model, the metal ceiling to be cut is placed in the positioning area of ​​the lower mold base 11, ensuring that the edge is aligned with the lower cutter 12. The hydraulic equipment is then activated to drive the upper mold base 1 to move downward, so that the upper mold base 1 and the lower mold base 11 together clamp the metal ceiling.

[0047] When the upper mold base 1 moves downward, the drive rod 14 contacts the limiting plate 32 and pushes the guide rod 3 to move upward, compressing the reset spring 33. The piston plate 31 moves upward with the guide rod 3, and a negative pressure is formed in the inner cavity of the support base 2. The one-way valve 23 of the liquid inlet pipe 21 is opened, and the coolant is drawn into the support base 2. The upper cutter 42 continues to move downward with the upper mold base 1 and cuts alternately with the lower cutter 12 to complete the cutting of the metal roof edge.

[0048] When the upper mold base 1 moves upward, the drive rod 14 disengages from the limit plate 32, the return spring 33 releases its elastic force, and pushes the piston plate 31 downward. The piston plate 31 moves downward and squeezes the coolant. The one-way valve 23 of the drain pipe 22 opens, and the flow of coolant absorbs the temperature of the fixed base 4 and the upper cutter 42, and carries away the heat before being discharged.

[0049] The upper cutter 42 moves upward with the upper mold base 1 and separates from the lower cutter 12, completing a single cutting cycle.
