Description

Technical Field

[0001] The utility model relates to the field of seal strip cutting equipment, in particular to a profile seal strip cutting device. Background Art

[0002] Aluminum profiles are widely used in the equipment and machinery manufacturing fields. To ensure sealing, aluminum profiles are usually used in conjunction with seals. When applying seals to aluminum profiles, it is necessary to drill holes in certain areas of the aluminum profile before tightening and assembling with screws. Therefore, the seals need to be cut where the holes need to be made. Currently, aluminum profile seals are mainly cut using manual tools such as scrapers and flat-nosed pliers, or removed using a heat gun to heat the seal, soften it, and then remove it with flat-nosed pliers. These shearing and removal methods have problems such as inaccurate positioning and easy damage to the profile appearance.

[0003] Patent application number CN109968418B discloses an automatic strip-cutting device for T5 LED integrated bracket lamps. The device consists of two separate automatic strip-cutting units, each performing separate automatic strip-cutting operations. These units comprise an automatic cutting plate movement control device, a negative pressure vacuum adsorption device for the LED soft-base strip light strip cutting plate, an automatic clamping and anti-shifting device for cutting the LED soft-base strip light strips, and an automatic cutting blade movement control device. While the first automatic strip-cutting unit completes the loading of two 35-piece LED soft-base strip light strips and proceeds to glue and apply the strips, the second unit loads the two 35-piece LED soft-base strip light strips. This device enables fully automated strip-cutting and gluing operations. However, it is not directly suitable for cutting seals on aluminum profiles. Utility Model Content

[0031] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In order to improve operational safety, avoid accidental injury by the cutting knife, and guide the movement of the cutting knife 7 and the drag rod 8, the bottom of the cylinder is connected to the cylinder frame 4, and the bottom of the cylinder frame 4 is connected to the fixing frame 13 through bolts 11. A tool holder accommodating cavity 16 for accommodating the tool holder 14 is opened in the fixing frame 13.

[0032] like Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, in order to improve operational safety, avoid accidental injury from the cutting knife, and guide the movement of the cutting knife 7 and the drag rod 8, a side pressure plate 6 is provided on the outer side of the fixing frame 13. A bottom plate 10 is provided at the bottom of the fixing frame 13, and the bottom plate 10 is respectively provided with a cutting knife clearance groove 27 for the cutting knife 7 to pass through and a drag rod clearance hole 28 for the drag rod 8 to pass through.

[0033] Specifically, if Figure 4 and Figure 5 As shown, the top of the fixing frame 13 is provided with a second threaded hole 18 for connecting to the cylinder frame 4 and a push-pull rod through hole 17 for the push-pull rod to pass through. The side wall of the fixing frame 13 is provided with a plurality of first threaded holes 15 for connecting to the side pressure plate 6.

[0034] like Figure 6 and Figure 7 As shown, the top of the tool holder 14 is provided with a pair of fourth threaded holes 20 for mounting the drag rod 8 and a third threaded hole 19 for connecting the push-pull rod 5. The lower portion of the tool holder 14 is provided with a pair of cutter mounting grooves 21 for mounting the cutter 7. First screw holes 22 are provided on both sides of the tool holder corresponding to the cutter mounting grooves 21, and the cutter 7 is detachably mounted in the cutter mounting grooves by screws.

[0037] Example 2

[0038] This embodiment provides a profile seal cutting device. The main difference from Example 1 is that in this embodiment, in order to press the seal before cutting it with a cutting knife to prevent the seal from warping and deviating, bosses 29 for pressing the profile seal are provided on both sides of the base plate 10.

[0039] Example 3

[0040] This embodiment provides a profile sealing strip cutting device. The main difference from Example 1 is that in this embodiment, in order to hold the lower side of the profile, the hook plate 9 is an L-shaped hook plate, and the L-shaped hook plate is connected to one side of the fixing frame 13 through a pad 12.

[0041] Example 4

[0042] This embodiment provides a profile seal cutting device. The main difference from Embodiment 1 is that, in this embodiment, to ensure that the cutter has already cut the seal when the drag rod is used to tie and lift the seal, the length of the cutter 7 is greater than the length of the drag rod 8. Specifically, during installation, the bottom height of the cutter is lower than the bottom height of the drag rod.

[0043] Specifically, the profile seal cutting device provided by the present invention has the following specific operating steps:

[0044] The operator holds the handle and uses the hook plate 9 to clamp the profile to be cut into the corresponding position under the knife holder 14. At this time, the part of the seal to be cut is aligned with the cutting knife, and the reversing valve 2 is pressed. The push-pull rod 5, driven by the two-way cylinder, drives the cutting knife 7 and the drag rod 8 in the knife holder accommodating chamber 16 to press the part of the seal to be cut.

[0045] Subsequently, the bosses 29 on either side of the base plate 10 press against the edges of the seal, the cutters 7 at each end of the tool holder 14 cut the seal, and the drag rod 8 in the middle penetrates the seal. The reversing valve 2 is then pressed again, reversing the direction of the cylinder. Driven by the cylinder, the push-pull rod 5 retracts to its initial position. This retraction drives the cutter 7 and the drag rod 8 upward, allowing the drag rod 8 to pull the seal to be cut out of the profile slot. When the seal reaches the base plate 10, the barrier of the base plate 10 disengages the drag rod 8, completing the cutting and removal of the seal.

[0046] The telescopic distance of the push-pull rod is determined by the stroke of the cylinder and the height of the tool holder accommodating cavity on the fixed plate.

[0047] In addition, for cutting longer seals, you can remove the cutter at one end and keep one end for cutting. When operating, aim the cutter at the part to be cut, repeat the above operation, drag the rod to bring out one end of the seal, and pull out the seal directly; then find the other end of the seal that needs to be cut and cut again.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
