Description

Technical Field

[0001] The present invention relates to the technical field of hardware processing, and particularly relates to a cutting device for hardware fittings. Background Art

[0002] Hardware fittings refer to machine parts or components obtained by processing and casting metals such as gold, silver, copper, iron, and tin. Generally, there are pulleys, joints, idler rollers, nozzles, hooks, etc. Among them, fasteners such as bolts are the most common. For hardware fittings such as tubular fasteners, due to sometimes errors in length measurement during actual use, it is often necessary to rework the hardware fittings and cut them according to the pipe length requirements.

[0003] Most of the existing cutting devices used for hardware fittings are desktop integrated cutting devices. Therefore, for hardware cutting, most of the hardware fittings are directly placed on the cutting table and cut using structures such as table saws. However, for small tubular hardware fittings such as bolts, it is often inconvenient to perform corresponding cutting as required. During actual hardware processing or use, sometimes it is necessary to temporarily modify the usage requirements of small tubular hardware fittings such as bolts and perform corresponding cutting according to the modified requirements. Traditional cutting devices are generally not convenient to carry and cannot be carried and used in a supporting manner during hardware processing or use. And for the cutting devices that are convenient to carry, most of them are single-handed cutting saw blades for ensuring cutting safety, and the other hand is used to cooperate with wearing a protective mask. However, such single-handed cutting saw blades are not convenient to clamp hardware fittings and adjust the corresponding cutting points during actual cutting, and the clamping function generally needs to be realized by adding other structures.

[0004] Therefore, this application specifically proposes a cutting device for hardware fittings to solve the above technical problems. Summary of the Invention

[0005] The main purpose of the present invention is to provide a cutting device for hardware fittings that is convenient to carry and can integrally perform single-handed clamping, cutting position adjustment, rapid cutting, and recycling of cutting waste on-site for hardware fittings as required.

[0006] The present invention adopts the following technical solutions to solve the above technical problems:

[0007] A cutting device for hardware fittings, comprising:

[0008] A device housing, with a waste collection block slidably arranged inside. An aggregate groove for collecting waste is provided on the waste collection block;

[0009] Two groups of clamping pressing plates, slidably arranged on the waste collection block. A conical extrusion sleeve for extruding and clamping hardware fittings is arranged on the side where the clamping pressing plates are close to each other;

[0010] The blade lifting assembly includes a lever lifting mechanism arranged on the waste collection block and a movable mechanism arranged at one end of the lever lifting mechanism;

[0011] The electric cutting blade is located inside the aggregate chute and is detachably installed at the other end of the lever lifting mechanism;

[0012] The clamping assembly is arranged on the lever lifting mechanism and is used to drive two groups of clamping pressure plates to approach each other;

[0013] During the downward pressing process of the clamping assembly, the lever lifting mechanism drives the electric cutting blade to lift and move to cut the clamped hardware fittings.

[0014] Preferably, the clamping assembly includes a connecting block hinged on the clamping pressure plate, a scissor arm main body hinged on the connecting block and used for folding to drive the connecting blocks to approach and move away from each other, a first telescopic rod arranged between the connecting blocks, and a compression spring sleeved outside the first telescopic rod.

[0015] Preferably, the clamping assembly further includes a scissor arm handle arranged on the scissor arm main body and an electric control switch arranged on the scissor arm handle and used for electrically connecting with the electric cutting blade.

[0016] Preferably, the movable mechanism includes an extension plate arranged at the bottom end of the waste collection block, a limit stop post arranged on the extension plate and used for limiting the movement of the clamping assembly, a support plate vertically moving and limited on the limit stop post, a moving plate slidably limited on the support plate, a mounting plate arranged on the clamping assembly, and a second sliding rod arranged on the moving plate and used for passing through the mounting plate.

[0017] Preferably, the lever lifting mechanism includes a lever rotation groove opened on the waste collection block, a blade mounting seat for detachably installing the electric cutting blade, a second telescopic rod hinged on the support plate and used for connecting the blade mounting seat, a lever rotating shaft arranged in the lever rotation groove and used for connecting the second telescopic rod to rotate the lever, and a lever stop block arranged in the lever rotation groove and used for limiting the rotation of the second telescopic rod.

[0018] Preferably, it further includes an engaging and flipping assembly arranged on the device housing and used for driving the conical extrusion sleeve to rotate. The engaging and flipping assembly includes a first sliding rod arranged on the device housing, two groups of mounting blocks slidably arranged on the first sliding rod, a limit sliding plate fixed on the mounting block and used for fitting and sliding inside the device housing, a rack arranged on the mounting block and used for passing through the clamping pressure plate, a limit stop block arranged on the rack, and a gear rotatably arranged inside the clamping pressure plate and used for engaging the rack to drive the conical extrusion sleeve to rotate synchronously.

[0019] Preferably, the bottom side of the aggregate trough is provided with a sliding inclined plane. A through groove is formed in the waste collection block at the lower inclined position of the sliding inclined plane, and a material collection through hole is formed at the bottom of the device housing below the through groove.

[0020] Preferably, the device housing and the waste collection block are fixed to each other through multiple groups of positioning components, and a movable handle is arranged on the device housing.

[0021] Preferably, the positioning component includes a positioning hole arranged on the side wall of the waste collection block and a fastening bolt arranged on the device housing for threadedly connecting the positioning hole.

[0022] The present invention provides a cutting device for hardware fittings. Compared with the prior art, the beneficial effects of the present invention are reflected in:

[0023] 1. By setting a clamping component that can be operated with one hand to control the clamping pressure plates to squeeze each other, since the tapered extrusion sleeves are arranged on the mutually approaching sides of the clamping pressure plates, the clamping component can be used to control the clamping of hardware fittings with one hand. Also, since a blade lifting component is arranged at the bottom of the clamping component, when the clamping component is pressed down to drive the movable mechanism to press down, the lever of the lever lifting mechanism can be driven to rotate, thereby driving the electric cutting blade to move towards the clamped hardware part to complete the cutting with one hand. At the same time, the movable mechanism can also ensure that the position of the electric cutting blade remains unchanged when the clamping component clamps and moves the hardware fitting. Therefore, it is convenient to operate with one hand for clamping, moving, and cutting hardware fittings, and the structure is simple and convenient for safe use.

[0024] 2. By setting an engaging and flipping component, since the electric cutting blade is detachably installed on the blade lifting component, the electric cutting blade on the blade lifting component can also be replaced with other hardware processing structures or cutting tool heads with different inclination angles. By controlling the clamping pressure plates to move in the device housing through the clamping component, the hardware fitting clamped in the tapered extrusion sleeve can be controlled to rotate, and different degrees or types of processing of the hardware fitting can be carried out in cooperation with different processing structures on the blade lifting component.

[0025] 3. By arranging a sliding inclined plane and a through groove in the aggregate trough of the waste collection block, and cooperating with the opening of the material collection through hole at the bottom of the device housing, the cutting waste can be sent into the corresponding collection bin through the sliding inclined plane, the through groove, and the material collection through hole in sequence for centralized treatment during the cutting of hardware fittings, which is environmentally friendly and economical.

[0026] 4. Since the waste collection block is slidably arranged in the device housing, the overall device structure can be concentrated by using the positioning component, which is convenient to carry as a whole in cooperation with the movable handle. Moreover, it can be used to clamp, adjust the cutting part, quickly cut, and recycle the cutting waste with one hand on-site according to the needs of hardware fittings, which is convenient for actual use.

[0041] In the embodiments, refer in detail to Figures 1 to 8 .

[0042] As Figure 1 and Figure 5 shown, the present invention provides a cutting device for hardware fittings, including:

[0043] A device housing 1, with a waste collection block 2 sliding inside it. An aggregate groove 21 for collecting waste is provided on the waste collection block 2;

[0044] Two groups of clamping pressure plates 4, sliding on the waste collection block 2. A conical extrusion sleeve 5 for squeezing and clamping the hardware fittings is provided on the side where the clamping pressure plates 4 are close to each other. A rubber film for improving the clamping ability of the hardware fittings is attached to the inner side of the conical extrusion sleeve 5;

[0045] The blade lifting assembly 9 includes a lever lifting mechanism 92 disposed on the waste collection block 2 and a movable mechanism 91 disposed at one end of the lever lifting mechanism 92;

[0046] The electric cutting blade 10 is located inside the aggregate chute 21 and is detachably installed at the other end of the lever lifting mechanism 92, and is used for cutting and processing the clamped hardware fittings after being driven by electric control;

[0047] The clamping assembly 7 is disposed on the lever lifting mechanism 92 and is used for an operator to drive two sets of clamping pressure plates 4 to approach each other with one hand. By setting the clamping assembly 7 that can be operated with one hand, the clamping pressure plates 4 are controlled to squeeze each other. Since the conical extrusion sleeves 5 are provided on the sides of the clamping pressure plates 4 that approach each other, the clamping assembly 7 can be used to clamp the hardware fittings with one hand.

[0048] Since the blade lifting assembly 9 is provided at the bottom of the clamping assembly 7, during the downward pressing of the clamping assembly 7, the movable mechanism 91 is driven to press downward by the downward pressing of the clamping assembly 7, and the lever of the lever lifting mechanism 92 can be driven to rotate, thereby driving the electric cutting blade 10 to lift and move toward the clamped hardware to cut the clamped hardware fittings;

[0049] At the same time, due to the setting of the movable mechanism 91, it can ensure that the position of the electric cutting blade 10 remains unchanged when the clamping assembly 7 clamps and moves the hardware fittings during the cutting use of the device. Therefore, it is convenient to operate with one hand for clamping, moving and cutting the hardware fittings, and the structure is simple and convenient for safe use.

[0050] In a specific implementation, the waste collection block 2 is slid out from the device housing 1, and both ends of the hardware parts to be cut are placed inside the conical extrusion sleeves 5. The clamping assembly 7 is used to manually control the two clamping pressure plates 4 to approach each other, thereby completing the clamping operation of the hardware fittings above the aggregate chute 21. Then, the clamping assembly 7 is manually pressed downward, and the movable mechanism 91 and the lever lifting mechanism 92 can drive the electric cutting blade 10 to move upward when the clamping assembly 7 is pressed downward, thereby completing the cutting operation of the clamped hardware fittings.

[0051] It should be noted that the electric cutting blade 10 mentioned in this application belongs to the prior art. It can be directly used by directly adopting the structure of an electric circular saw as shown in the drawings, or it can be replaced by using prior art such as an electric cutting machine. Therefore, the working principle and usage method of the electric cutting blade 10 will not be elaborated here.

[0052] As Figure 2 and Figure 3 shown, the clamping assembly 7 includes a connecting block 72 hinged to the clamping pressure plate 4, a scissor arm main body 71 hinged to the connecting block 72 for folding and driving the connecting blocks 72 to approach and separate from each other, a first telescopic rod 73 disposed between the connecting blocks 72, and a compression spring 74 sleeved outside the first telescopic rod 73.

[0053] In specific implementation, when the main body 71 of the scissors arm is in an unloaded state, the first telescopic rod 73 cooperates with the compression spring 74 to control the two connecting blocks 72 to drive the clamping pressing plate 4 to move away from each other. At this time, it is convenient to place the hardware fitting to be cut into the conical extrusion sleeve 5 for clamping use. When the main body 71 of the scissors arm is in a stressed state, the conical extrusion sleeves 5 squeeze each other to complete the extrusion clamping operation of the hardware fitting.

[0054] In addition, the clamping assembly 7 further includes a scissors arm handle 75 provided on the main body 71 of the scissors arm and an electric control switch 76 provided on the scissors arm handle 75 for electrically connecting with the electric cutting blade 10. When the hardware fitting is in a clamped state, the electric control switch 76 is used to drive the electric cutting blade 10 to operate. In cooperation with the blade lifting assembly 9, when the clamping assembly 7 presses down, the lever force drives the electric cutting blade 10 to move towards the clamped hardware fitting, and the cutting operation of the hardware fitting can be completed.

[0055] As Figure 4 and Figure 5 shown, the moving mechanism 91 includes an extension plate 911 provided at the bottom end of the waste collection block 2, a limit stop post 912 provided on the extension plate 911 for limiting the movement of the clamping assembly 7, a support plate 913 vertically moving in a limited manner on the limit stop post 912, a moving plate 914 sliding in a limited manner on the support plate 913, a mounting plate 915 provided on the clamping assembly 7, and a second sliding rod 916 provided on the moving plate 914 for passing through the mounting plate 915. When the limit stop post 912 is specifically used, it can not only limit the folding and opening of the clamping assembly 7, but also limit the up and down movement of the support plate 913 through the sliding assembly 8.

[0056] In specific implementation, since the clamping assembly 7 is provided on the second sliding rod 916 through the mounting plate 915, the clamping assembly 7 can drive the conical extrusion sleeve 5 and the clamped hardware fitting to move through the clamping pressing plate 4. At this time, since only the mounting plate 915 in the moving mechanism 91 moves along the length direction of the second sliding rod 916 on the moving plate 914, it can ensure that the position of the electric cutting blade 10 remains unchanged when the clamping assembly 7 clamps and moves the hardware fitting, thereby facilitating the adjustment and control of the cutting position after the hardware fitting is clamped. When the clamping assembly 7 folds and is forced to clamp the hardware fitting, since the moving plate 914 slides in a limited manner on the support plate 913, and the support plate 913 can move up and down relative to the waste collection block 2 through the limit stop post 912 and the extension plate 911, it can ensure that the clamping assembly 7 can normally move down to drive the lever of the lever lifting mechanism 92 to rotate.

[0057] At the same time, as Figure 5As shown, the lever lifting mechanism 92 includes a lever rotation groove 923 formed in the waste collection block 2, a blade mounting seat 925 for detachably mounting the electric cutting blade 10, a second telescopic rod 921 hinged on the support plate 913 for connecting the blade mounting seat 925, a lever rotating shaft 922 disposed in the lever rotation groove 923 for connecting the second telescopic rod 921 to rotate the lever, and a lever stopper 924 disposed in the lever rotation groove 923 for limiting the rotation of the second telescopic rod 921. The lever stopper 924 can prevent the electric cutting blade 10 from moving downward excessively to cause the blade to contact the inner bottom wall of the aggregate tank 21, avoiding damage to the waste collection block 2 and improving the service life of the device.

[0058] When the clamping assembly 7 presses down to drive the support plate 913 to move downward, since the support plate 913 is hinged to one end of the second telescopic rod 921, and since the outer cylinder of the second telescopic rod 921 rotates in the lever rotation groove 923 through the lever rotating shaft 922, at this time, the lever can drive the electric cutting blade 10 to move upward.

[0059] In addition, as Figure 7 shown, since the electric cutting blade 10 is detachably mounted on the blade mounting seat 925, the electric cutting blade 10 can also be replaced and installed with cutting heads of different processing structures or different inclination angles according to the actual use of on-site hardware fittings. When the electric cutting blade 10 is replaced with other processing structures, the device further includes an engagement and flipping assembly 6 disposed on the device housing 1 for driving the conical extrusion sleeve 5 to rotate. The engagement and flipping assembly 6 includes a first sliding rod 65 disposed on the device housing 1, two sets of mounting blocks 64 slidably mounted on the first sliding rod 65, a limiting sliding plate 66 fixed on the mounting block 64 for slidingly fitting inside the device housing 1, a rack 62 disposed on the mounting block 64 for passing through and clamping the pressing plate 4, a limiting block 63 disposed on the rack 62, and a gear 61 rotatably disposed inside the clamping pressing plate 4 for engaging the rack 62 to drive the conical extrusion sleeve 5 to rotate synchronously.

[0060] In specific implementation, when the clamping assembly 7 controls the clamping of the hardware fitting and presses down for processing, the clamping assembly 7 can drive the clamping pressing plate 4 and the waste collection block 2 to move synchronously inside the device housing 1. At this time, since the rack 62 slides through the clamping pressing plate 4, it meshes and drives the gear 61 to rotate. Since the conical extrusion sleeve 5 is connected to the gear 61, it can drive the conical extrusion sleeve 5 and the clamped hardware fitting to rotate synchronously, and then cooperate with different processing structures on the blade lifting assembly 9 to perform different degrees or types of processing on the hardware fitting.

[0061] As Figure 5As shown, the bottom side of the aggregate chute 21 is set as a sliding inclined plane 22. A through groove 23 is opened on the waste collection block 2 at the lower inclined position of the sliding inclined plane 22. A material collection through hole 12 is opened at the bottom of the device housing 1 below the through groove 23. Before the device is used, the material collection through hole 12 should be placed at the upper opening of the collection bin. When cutting hardware fittings, by setting the sliding inclined plane 22 and the through groove 23 in the aggregate chute 21 of the waste collection block 2, and cooperating with the opening of the material collection through hole 12 at the bottom of the device housing 1, the cutting waste can be successively sent into the corresponding collection bin through the sliding inclined plane 22, the through groove 23 and the material collection through hole 12 for centralized treatment, which is environmentally friendly and economical.

[0062] As Figure 6 and Figure 8 shown, the device housing 1 and the waste collection block 2 are fixed to each other by multiple sets of positioning components 3. An activity handle 11 is provided on the device housing 1. Among them, the positioning component 3 includes a positioning hole 31 provided on the side wall of the waste collection block 2 and a fastening bolt 32 provided on the device housing 1 for threadedly connecting the positioning hole 31. Since the waste collection block 2 is slidably arranged in the device housing 1, the positioning component 3 can be used to centrally integrate the device structure. Cooperating with the activity handle 11, it is convenient to carry the whole device, and it can be used to hold, adjust the cutting part, quickly cut, and recycle the cutting waste with one hand on-site according to the needs of hardware fittings, which is convenient for actual use.

[0063] Finally, it should be noted that as shown in the drawings, during the operation and use of the device, the limited sliding of the waste collection block 2 in the device housing 1, the limited sliding of the clamping pressing plate 4 on the waste collection block 2, the limited sliding of the moving plate 914 on the supporting plate 913, and the limited sliding of the supporting plate 913 on the limit stop post 912 are all realized by the sliding component 8. Among them, the sliding component 8 includes a limit sliding groove 81 (such as 81a, 81b, 81c, 81d shown in the drawings) and a limit sliding block 82 (such as 82a, 82b, 82c, 82d shown in the drawings) sliding in the limit sliding groove 81.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
