Description

Technical Field

[0001] The invention relates to the technical field of door and window processing and manufacturing, and in particular to a metal frame cutting device used for manufacturing wooden doors and windows. Background Art

[0002] With the widespread application of wooden doors and windows in the field of architectural decoration, their quality and safety have attracted much attention. In order to improve the durability of wooden doors and windows, metal frames are often set on the surface of doors and windows. In the production process of metal frames, a cutting device is required to cut the metal profile into the required size.

[0003] At present, the problem of sparks flying everywhere during the cutting of metal profiles is particularly prominent. For wooden door and window manufacturers, wood used for the production of doors and windows is usually piled up in the factory, which makes the flying sparks a major hidden danger of causing fire. Existing metal frame cutting devices generally have a protective cover around the tool, but in order to prevent the protective cover from interfering with the tool cutting and thus causing the metal to be unable to be completely cut off, the protective cover usually cannot completely surround the tool. In this way, sparks will still splash out from around the tool during the cutting process, which cannot effectively solve the problem of fire hazards, bringing great safety challenges to the production of wooden doors and windows.

[0004] In view of this, we propose a metal frame cutting device for wooden door and window manufacturing to improve the deficiencies in the prior art. Summary of the invention

The protective mechanism applies downward pressure to the metal profile to be cut, and the protective mechanism can prevent metal debris generated by the cutting mechanism from splashing. In the process of the protective mechanism contacting the metal profile and applying pressure, the protective mechanism automatically removes the internal metal debris.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] In order to prevent metal sparks from flying and not affect the cutting of the metal profile by the cutting mechanism 30, the protection mechanism 40 is set to a structure with a "hollow middle part and concave sides". Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a metal frame cutting device for manufacturing wooden doors and windows, including an operating table 12 arranged on the top of a base 11, the tops of the two side edges of the operating table 12 that are far away from each other are provided with retaining edges 13, a cutting groove 14 is opened on the top of the operating table 12, a clamping mechanism 20 is provided on the top of the operating table 12 on one side of the cutting groove 14, and a cutting mechanism 30 and a protective mechanism 40 are provided above the cutting groove 14 in sequence from top to bottom;

[0032] The clamping mechanism 20 is used to fix the two sides of the metal profile to be cut, and the cutting mechanism 30 cuts the fixed metal profile. During the process of the cutting mechanism 30 cutting the metal profile, the protective mechanism 40 follows the cutting mechanism 30 and approaches the metal profile synchronously. The protective mechanism 40 continuously applies downward pressure to the metal profile to be cut, and the shape design of the protective mechanism 40 "hollow in the middle and concave on both sides" can prevent the metal debris generated by the cutting mechanism 30 from splashing around. From the time the protective mechanism 40 contacts the metal profile to the time the cutting of the profile is completed, the protective mechanism 40 can automatically remove the internal metal debris. At the same time, during the process of the protective mechanism 40 removing the internal debris, the protective mechanism 40 can buffer the profile.

[0033] Working principle: First, place the metal profile to be cut in the clamping mechanism 20 and fix it, then start the cutting mechanism 30 to approach the fixed metal profile and cut it. At the same time, the protection mechanism 40 follows the cutting mechanism 30 to approach the metal profile synchronously and continuously applies downward pressure to the surface of the metal profile to be cut. From the time the protection mechanism 40 contacts the metal profile to the time the profile is cut, the protection mechanism 40 can automatically remove the metal debris inside. At the same time, in the process of the protection mechanism 40 removing the internal debris, a buffer force is applied to the surface of the metal profile in the opposite direction of the movement of the cutting mechanism 30.

[0034] In order to fix the left and right sides of the metal profile to be cut, to prevent it from shaking left and right during the cutting process, which may cause damage to the metal door and window frame. Figure 3 and Figure 4 As shown, the clamping mechanism 20 includes a pair of symmetrically arranged clamping arms, two clamping arms are used to fix the metal profile to be cut, and the clamping arms include a plurality of guide rods 21 slidably connected to the retaining edge 13, and a plurality of guide rods 21 are fixedly connected to a slot 22 at one end close to the profile, and a first spring 23 is sleeved on the outer periphery of the guide rod 21 between the slot 22 and the retaining edge 13, and a clamping block 24 is provided on the side of the slot 22 close to the metal profile.

[0035] The improvement lies in that: when fixing the metal profile frame that needs to be cut, first, push the two clamping blocks 24 apart from each other, drive the guide rod 21 to slide along the retaining edge 13, and compress the first spring 23, place the metal profile between the two clamping blocks 24, and then remove the thrust applied to the two clamping blocks 24. At this time, the two clamping blocks 24 are reset under the action of the restoring force of the first spring 23, thereby fixing the left and right sides of the metal profile.

[0036] In order to cut the metal profile into the required size, Figure 5 In the figure, the cutting mechanism 30 includes a hydraulic rod 32 arranged on one side of the retaining edge 13, a mounting seat 31 is provided on the top of the hydraulic rod 32, the mounting seat 31 is fixedly connected to the movable end of the hydraulic rod 32, a tool 33 is rotatably connected to one side of the mounting seat 31, the tool 33 is located above the cutting groove 14, and a protective cover 34 is provided on the outer periphery of the tool 33.

[0037] The improvement lies in that the cutter 33 is driven by a motor. After the motor is powered on, the motor drives the cutter 33 coaxially connected to its own output shaft to rotate, and then starts the hydraulic rod 32. The hydraulic rod 32 retracts the telescopic arm, driving the cutter 33 on the mounting seat 31 to approach the metal profile located at the top of the cutting groove 14, thereby cutting the metal profile.

[0038] Among them, the theoretical analysis of the driving force provided by the hydraulic rod 32 to retract the telescopic arm is as follows: the driving force of the hydraulic rod 32 mainly depends on its working pressure and piston area. According to Pascal's law, the pressure in the hydraulic system is equal in all directions, and the driving force F of the hydraulic rod 32 can be calculated by the formula F=P*A, where P is the pressure of the hydraulic system, and A is the effective area of ​​the piston in the hydraulic rod 32. If the hydraulic system can provide a high enough pressure and the piston area of ​​the hydraulic rod 32 is reasonably designed, then in theory the hydraulic rod 32 can generate sufficient driving force when retracting the telescopic arm. For example, the piston radius r of a hydraulic rod 32 is 25 mm, and the working pressure of the hydraulic system is 10 MPa. According to the area formula of a circle A=πr 2 π is taken as 3.14, the effective area of ​​the piston A = 0.001962.5m 2 The driving force F=19625N can be calculated by the formula F=P×A. Such a driving force is quite considerable in many practical application scenarios. Therefore, the hydraulic rod 32 retracting the telescopic arm can provide sufficient driving force for the entire cutting mechanism 30 to descend for cutting and ascend for resetting.

[0039] The existing metal frame cutting device generally sets a protective cover 34 around the cutter 33, but in order to prevent the protective cover 34 from interfering with the cutting of the cutter 33 and thus causing the metal to be unable to be completely cut, the protective cover 34 usually cannot completely surround the cutter 33. As a result, sparks will still splash out from around the cutter 33 during the cutting process, which cannot effectively solve the fire hazard problem and brings great safety challenges to the production of wooden doors and windows.

[0040] like Figure 6 and Figure 7 As shown, the specific structure of the protection mechanism 40 is disclosed below. The protection mechanism 40 includes a shell 41 fixedly connected to the bottom of the clamping block 24. The shell 41 is provided with a cutting cavity 42 in a direction parallel to the first spring 23. The shell 41 is symmetrically provided with a pair of chip blocking cavities 43 in a direction perpendicular to 52.

[0041] In addition, the protection mechanism 40 also includes a pair of contact blocks 46 respectively connected to the inside of the two chip blocking chambers 43 in a sliding manner, and the top of each contact block 46 is fixedly connected to a plurality of slide bars 44, and the plurality of slide bars 44 are connected to the top of the chip blocking chamber 43 in a sliding manner, and a limit bolt 45 is provided on the top of each slide bar 44, and a second spring 47 is sleeved on the periphery of each slide bar 44 between the limit bolt 45 and the chip blocking chamber 43;

[0042] It should be noted that: when the shell 41 moves downward synchronously with the protective cover 34, since the initial state of the contact block 46 is located at the bottom of the chip blocking chamber 43, the contact block 46 first contacts the surface of the metal profile. As the shell 41 continues to move downward, the slide bar 44 slides upward along the top of the chip blocking chamber 43 to compress the second spring 47. The shortened second spring 47 absorbs part of the energy of the shell 41 pressing down to prevent the metal profile from being deformed due to excessive pressure on the metal profile. Since the shell 41 is "hollow in the middle and concave on both sides", the hollow cutting chamber 42 allows the tool 33 to work normally inside, and the concave chip blocking chamber 43 ensures that during the cutting process, the profile can gradually enter the inside of the chip blocking chamber 43, and ensures that: the sinking distance of the shell 41 is equal to the distance that the metal profile enters the chip blocking chamber 43, thereby ensuring that the sparks generated by the tool 33 cutting the profile are always located in the cutting chamber 42 and the chip blocking chamber 43, preventing the sparks from splashing around and reducing the possibility of fire.

[0043] Moreover, the tool 33 will generate sparks when cutting the metal profile, and these sparks are actually molten metal debris. That is to say, after the sparks splash onto the inner wall of the chip retaining cavity 43, they will adhere to the inner wall of the chip retaining cavity 43. After the metal debris cools and hardens, it will scratch the metal profile.

[0044] Figure 6 and Figure 7 The inclined orientation of the contact block 46 inside the chip blocking chamber 43 is shown, and then the specific shape of the contact block 46 is disclosed. The thickness of the contact block 46 gradually decreases from the side away from the cutting chamber 42 to the side close to the cutting chamber 42, and both sides of the contact block 46 are closely attached to the inner wall of the chip blocking chamber 43;

[0045] It should be noted that when the contact block 46 slides upward along the chip blocking chamber 43, the contact block 46 slides along the inner wall of the chip blocking chamber 43, scraping off the metal debris adhering to the inner wall of the chip blocking chamber 43, and the metal debris falls to the top of the contact block 46. Then, the vibration during the operation of the motor will vibrate the metal debris that falls on the top of the contact block 46 into the cutting chamber 42, and then fall into the cutting groove 14.

[0046] In summary, the working principle of the present invention is as follows:

[0047] First, the metal profile to be cut is placed on the two clamping blocks 24 and fixed, and then the hydraulic rod 32 is started to drive the rotating cutter 33 to approach the fixed metal profile and cut it.

[0048] When the shell 41 moves downward synchronously with the protective cover 34, since the initial state of the contact block 46 is located at the bottom of the chip blocking chamber 43, the contact block 46 first contacts the surface of the metal profile. As the shell 41 continues to move downward, the slide bar 44 slides upward along the top of the chip blocking chamber 43 to compress the second spring 47. The shortened second spring 47 absorbs part of the downward pressure energy of the shell 41 to prevent the metal profile from being deformed due to excessive pressure on the metal profile. The hollow cutting chamber 42 allows the tool 33 to work normally inside, and the upwardly recessed chip blocking chamber 43 ensures that during the cutting process, the profile can gradually enter the chip blocking chamber 43, and ensures that: the distance that the shell 41 sinks is equal to the distance that the metal profile enters the chip blocking chamber 43, thereby ensuring that the sparks generated by the tool 33 cutting the profile are always located in the cutting chamber 42 and the chip blocking chamber 43, preventing the sparks from flying around.
