[0034] The technical solutions of the present utility model will now be described with reference to the accompanying drawings of the embodiments. The embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0035] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0036] Please see Figures 1 to 12 This utility model provides a sheet cutting equipment, the technical solution of which is as follows:

[0037] A sheet cutting equipment includes: a machine body 1, and a cutting device 2 fixedly connected to the machine body 1; the cutting device 2 includes a clamping component 21 and a pressing and snapping component 22, the clamping component 21 includes a cutting frame 212, the cutting frame 212 is fixedly connected to the machine body 1, a groove 2121 is formed at the center of the cutting frame 212, two symmetrical first wedge-shaped clamping blocks 213 are fixedly connected to both sides of the groove 2121, and first wedge blocks 214 are slidably connected between the first wedge clamping blocks 213;

[0038] The first wedge block 214 has a snap-fit ​​groove 215 at its bottom, and a support plate 216 is fixedly connected inside the snap-fit ​​groove 215. The top of the support plate 216 is slidably connected to the snap-fit ​​hook 226 in the snap-fit ​​assembly 22.

[0039] The sheet cutting equipment is supported by a welded steel machine body 1. The cutting device 2 is bolted to the front operating plane of the machine body 1. Its core clamping component 21 includes a cutting frame 212 made of cast aluminum alloy, with an annular groove 2121 machined in the center of the cutting frame 212. Two sets of first wedge-shaped clamping blocks 213 with inclined surfaces are installed on each side of the long side of the groove 2121. Each set is symmetrically arranged. The inclined surfaces of the first wedge-shaped clamping blocks 213 and the first wedge-shaped blocks 214 form a wedge-shaped connection. The wedge-shaped fit produces a self-locking effect, solving the problem of loosening caused by screw and nut fixing. The bottom surface of the first wedge block 214 is machined with a snap-fit ​​groove 215, and the internal fixed connection support plate 216 provides the support condition for snap-fit. The support plate 216 cooperates with the snap-fit ​​hook 226 of the pressing snap-fit ​​component 22.

[0040] like Figures 6 to 8 As shown, the press-fit assembly 22 includes a blade 221. Two through slots 2211 are formed on the top of both sides of the blade 221. The size of the two through slots 2211 is the same as that of the snap-fit ​​slot 215.

[0041] The blade 221 is made of cemented carbide and has two rectangular through slots 2211 on its top. The dimensional tolerance between the through slots 2211 and the snap-fit ​​slot 215 is controlled within ±0.1mm. The edges of the through slots 2211 are chamfered to ensure smooth insertion of the snap-fit ​​hook 226. When installing the blade 221, the axis of the through slots 2211 is aligned with the axis of the snap-fit ​​slot 215.

[0042] like Figure 9 and Figure 10 As shown, pressing grooves 2212 are symmetrically opened on both sides of the blade 221. Pressing blocks 222 are slidably connected to the outside of the two pressing grooves 2212. A connecting plate 223 is fixedly connected to one side of the pressing block 222.

[0043] Two pressing grooves 2212 are symmetrically machined in the thickness direction of the blade 221. Stainless steel pressing blocks 222 are installed in the grooves. The gap between the pressing blocks 222 and the groove wall is maintained at 0.1-0.2mm. The pressing blocks 222 are rigidly connected to the connecting plate 223.

[0044] like Figure 7 and Figure 8 As shown, two fixed posts 224 are fixedly connected to the center of the connecting plate 223. A pressing spring 225 is wound around the two fixed posts 224. One end of the pressing spring 225 is fixedly connected to the connecting plate 223, and the other end of the pressing spring 225 is fixedly connected to the inner wall of the pressing groove 2212. A moving groove 2213 is opened in the inner wall of the pressing groove 2212. The fixed posts 224 are slidably connected inside the moving groove 2213. The two ends of the connecting plate 223 are symmetrically fixedly connected to the snap hooks 226. The snap hooks 226 pass through the through groove 2211 and slidably connect to the top of the support plate 216.

[0045] Two fixing posts 224 are welded to the center of the connecting plate 223. Pressing springs 225 are wound around the two fixing posts 224. A moving groove 2213 is opened on the inner wall of the pressing groove 2212. One end of the pressing spring 225 is riveted to the connecting plate 223, and the other end is riveted to the groove opening of the moving groove 2213. The moving groove 2213 is designed as an elongated hole structure, which is clearance-fitted with the fixing posts 224. The hook head of the snap hook 226 is machined with a guide chamfer to ensure the smooth cutting of the snap hook 226. The blade 221 can be detached by pressing the pressing block 222.

[0046] like Figure 6 and Figure 7 As shown, balancing components 23 are fixedly installed on the other two sides of the groove 2121. The balancing components 23 include two second wedge-shaped clamping blocks 231. A second wedge-shaped block 232 is slidably connected between the two second wedge-shaped clamping blocks 231. The bottom of the second wedge-shaped block 232 contacts the top of both ends of the blade 221.

[0047] The slitting frame 212 has balancing components 23 installed on both sides of the short side of the groove 2121. These components include two surface-hardened second wedge-shaped clamping blocks 231. The inclined surfaces of the second wedge-shaped clamping blocks 231 and the second wedge-shaped blocks 232 form a wedge-shaped connection. This wedge-shaped fit creates a self-locking effect, solving the problem of loosening that can occur when using screws and nuts. The function of the balancing components 23 is to ensure that the blade 221 is subjected to symmetrical forces during operation.

[0048] like Figure 11 and Figure 12 As shown, the outer side of the first wedge-shaped clamping block 213 and the outer side of the second wedge-shaped clamping block 231 are respectively fixedly connected to the inner wall of the groove 2121, and the top of the first wedge-shaped clamping block 213 and the top of the second wedge-shaped clamping block 231 are respectively fixedly connected to the inner wall of the groove 2121.

[0049] The outer surfaces of the first wedge-shaped clamping block 213 and the second wedge-shaped clamping block 231 are fixedly connected to both sides of the inner wall of the groove 2121, and the tops of the first wedge-shaped clamping block 213 and the second wedge-shaped clamping block 231 are fixedly connected to the top wall of the groove 2121.

[0050] The surfaces of the first wedge-shaped clamping block 213 and the first wedge-shaped block 214 that are in contact are made of elastic material, and the surfaces of the second wedge-shaped clamping block 231 and the second wedge-shaped block 232 that are in contact are made of elastic material.

[0051] The working surface of the first wedge-shaped clamping block 213 is made of polyurethane elastomer. When the first wedge-shaped block 214 is subjected to a vertical force, it moves upward. While the first wedge-shaped block 214 moves upward, it squeezes the inclined surface of the first wedge-shaped clamping block 213 to both sides. The polyurethane elastomer on the inclined surface of the first wedge-shaped clamping block 213 provides the space required for the first wedge-shaped block 214 to move upward and can effectively clamp the first wedge-shaped block 214, forming a wedge-shaped self-locking effect. Similarly, the second wedge-shaped clamping block 231 and the second wedge-shaped block 232 also form a wedge-shaped self-locking function.

[0052] Working principle: The operator presses the pressing blocks 222 on both sides of the blade 221 at the same time. The pressing blocks 222 push the connecting plate 223, and the connecting plate 223 squeezes the pressing spring 225, thereby pushing the locking hook 226 to move in the through groove 2211. Because the through groove 2211 and the locking groove 215 are aligned, the locking hook 226 can be locked into the locking groove 215. When the pressing blocks 222 on both sides are released, the reaction force of the pressing spring 225 locks the locking hook 226 onto the support plate 216 to form a detachable connection structure. After the locking is completed, when the equipment is working, the blade 221 squeezes the first wedge block 214. The inclined surface of the first wedge block 214 and the inclined surface of the first wedge clamping block 213 form a wedge self-locking function. The elastic material of the inclined surface of the first wedge clamping block 213 provides space for the first wedge block 214 to move and also makes the first wedge clamping block 213 and the first wedge block 214 fit together more tightly.

[0053] Embodiments of the present invention have been shown and described. Those skilled in the art will be able to make various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
