Description

Technical Field

[0001] The utility model relates to the field of cutting knife dies, in particular to an assembled leather sample cutting knife die. Background Art

[0002] A knife die is a mold for punching products. In traditional leather sample production, leather is mostly cut manually, which causes the cutting position to easily shift, affecting the final production quality of the leather sample. With the development of society, the emergence of knife dies has improved this problem. According to the shape of the leather sample, knife dies of corresponding size and shape are prepared in advance, and then the leather sample is placed under the knife die, and then stamping is performed. Leather samples of the required size and shape can be cut out at one time, greatly improving the efficiency and accuracy of leather sample cutting.

[0003] According to an assembled leather test sample cutting knife die with the application document publication number "CN210336230U" in the existing Chinese patent literature, it can be known from its recorded content that: a plurality of corner pieces are used to clamp and fix the blade, and when the shape of the knife die needs to be changed, the plurality of corner pieces and the blade are disassembled and reassembled, and the knife die is assembled into different knife dies by setting a detachable knife die body, so that the leather material can be better cut by a cutting machine, and can be assembled into different specifications to facilitate cutting into experimental samples;

[0004] However, in actual use, since there are a large number of corner pieces and blades, they need to be spliced ​​one by one after disassembly, which results in a waste of time in the splicing process.

[0005] Therefore, it is necessary to provide a new assembled leather sample cutting knife die to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an assembled leather sample cutting die.

[0007] The utility model provides an assembled leather sample cutting die, comprising a corner piece, wherein four corner pieces are provided, blades are provided between the bottoms of the corner pieces, one side of the corner piece is fixedly connected to a mounting seat, and the mounting seat is rotatably connected to a connecting rod, the surface of the connecting rod is provided with three evenly distributed scale plates, and the scale units on each of the scale plates are different.

[0008] Preferably, a collar is fixedly connected to the other side of the corner piece, and a positioning hole is provided on the top of the collar. The collar on each corner piece is sleeved on a connecting rod on another adjacent corner piece, and the collar and the connecting rod are slidably connected.

[0009] Preferably, an "L"-shaped mounting plate is fixedly connected to the inner wall of the corner piece, and a plurality of springs are fixedly connected to the bottom of the mounting plate, and an extrusion plate is fixedly connected between the bottom ends of the springs.

[0010] Preferably, the mounting seats are all provided with mounting holes, and a plurality of arc-shaped limiting plates are fixedly connected to the inner walls of the mounting holes.

[0011] Preferably, a mounting rod is rotatably connected in each of the mounting holes, and one end of the mounting rod is fixedly connected to the connecting rod. A plurality of fixedly connected limit bars are provided on the mounting rod, and the limit bars are mutually engaged with the limit plates at corresponding positions.

[0012] Preferably, a slot is provided at the bottom of each corner piece, and the blade is fixed to the corner piece by means of the slot.

[0013] Preferably, one end of the connecting rod away from the mounting seat is fixedly connected to a turning handle, and a plurality of anti-slip grooves are provided on the turning handle.

[0014] Compared with the related art, the assembled leather sample cutting knife mold provided by the utility model has the following advantages:

[0015] Beneficial effects:

[0016] 1. The utility model utilizes the connection rod and the sleeve ring to change the distance between the corner pieces. The distance between the corner pieces is changed in advance to be the same as the length of the blade through the scale value on the scale plate. After that, the subsequent blade is directly clamped on the corner piece to complete the assembly of the knife mold, avoiding the problem of low splicing efficiency caused by only being able to connect a single corner piece with the blade in sequence.

[0017] 2. In the cutting process of the utility model, the extrusion plate will be against the leather sample before the blade. At this time, the extrusion plate is used to fix the leather sample. Later, when cutting, the blade sinks into the leather sample, and the extrusion plate will continue to stay on the surface of the leather sample and contract the spring. When the cutting is completed, the blade is lifted, the pressure on the spring disappears, and it rebounds. The extrusion plate is used to push the leather sample stuck on the blade off, avoiding the problem that the leather sample sticks to the side wall of the blade after the traditional knife die cuts the leather sample because the leather sample has a certain ductility and viscosity.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 5 An assembled leather sample cutting die provided by an embodiment of the utility model includes a corner piece 1, four of which are provided, blades 12 are provided between the bottoms of the corner pieces 1, and a card slot 11 is provided at the bottom of each of the corner pieces 1, and the blades 12 are fixed to the corner pieces 1 by the card slot 11.

[0027] It should be noted that the four corner pieces 1 cooperate with each other to form a square corner frame, and the four corner pieces 1 are used to fix the two ends of the blade 12 respectively. The blade 12 can be fixed by clamping it in the slot 11. The clamping method can better disassemble and install the blade 12.

[0028] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 A mounting seat 2 is fixedly connected to one side of the corner piece 1, and each mounting seat 2 is provided with a mounting hole 21, and a plurality of arc-shaped limiting plates 22 are fixedly connected to the inner wall of the mounting hole 21;

[0029] A connecting rod 3 is rotatably connected to the mounting seat 2, and three evenly distributed scale plates 31 are provided on the surface of the connecting rod 3, and the scale units on each scale plate 31 are different. A mounting rod 32 is rotatably connected in the mounting hole 21, and one end of the mounting rod 32 is fixedly docked with the connecting rod 3. A plurality of fixedly connected limit strips 33 are provided on the mounting rod 32, and the limit strips 33 are mutually engaged with the limit plates 22 at corresponding positions. A rotating handle 34 is fixedly connected to the end of the connecting rod 3 away from the mounting seat 2, and a plurality of anti-slip grooves are provided on the rotating handle 34.

[0030] It should be noted that the mounting seat 2 can be used to mount the connecting rod 3, so that the connecting rod 3 is more stable when rotating. The limiting plate 22 in the mounting hole 21 cooperates with the limiting strip 33 on the mounting rod 32 to limit the connecting rod 3, so that the connecting rod 3 is in a fixed state.

[0031] It should also be noted that: when in use, the distance between the corner pieces 1 is adjusted according to the length of the blade 12 to be installed, and the connecting rod 3 is used in conjunction with the ring 4 on the other corner piece 1 to limit the two corner pieces 1. At the same time, when adjusting the distance between the corner pieces 1, the connecting rod 3 can be rotated using the turning handle 34 as needed to rotate the scale plate 31 of the required specified scale unit to the top. When the scale plate 31 is located directly above, the limit strip 33 will continue to be stuck on the inner wall of the limit plate 22. At this time, the distance between each corner piece 1 can be accurately positioned through the scale value on the scale plate 31.

[0032] In the embodiments of the present invention, please refer to Figure 3 A collar 4 is fixedly connected to the other side of the corner piece 1, and a positioning hole 41 is provided on the top of the collar 4. The collar 4 on each corner piece 1 is sleeved on the connecting rod 3 on another adjacent corner piece 1, and the collar 4 and the connecting rod 3 are slidably connected.

[0033] It should be noted that the collar 4 is used in conjunction with the connecting rod 3 on the adjacent corner piece 1 to limit the connecting rod 3. At the same time, when adjusting the values ​​between the corner pieces 1, the values ​​on the scale plate 31 can be viewed through the positioning hole 41. The distance between the corner pieces 1 can be determined by combining the positioning hole 41 with the scale plate 31.

[0034] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 An "L"-shaped mounting plate 5 is fixedly connected to the inner wall of the corner piece 1, and a plurality of springs 51 are fixedly connected to the bottom of the mounting plate 5, and an extrusion plate 52 is fixedly connected between the bottom ends of the springs 51.

[0035] It should be noted that: when cutting the leather sample, the extrusion plate 52 will first rest against the surface of the leather sample, and then the blade 12 will be pressed down. At this time, since the extrusion plate 52 is limited by the leather sample, it will compress the spring 51, causing the spring 51 to contract. At this time, the extrusion plate 52 will limit and fix the leather sample, making the blade 12 more stable and accurate during the cutting process. After the blade 12 completes the cutting, it begins to rise. When the blade 12 is pulled out of the leather sample, the pressure on the spring 51 disappears, and it begins to rebound, driving the extrusion plate 52 to move downward. At this time, the extrusion plate 52 can squeeze and remove the leather sample stuck to the side wall of the blade 12.

[0036] The working principle of the assembled leather sample cutting die provided by the utility model is as follows:

[0037] First, the distance between the corner pieces 1 is adjusted according to the length of the blade 12 to be installed, and the connecting rod 3 is used to cooperate with the collar 4 on the other corner piece 1 to limit the two corner pieces 1. At the same time, when adjusting the distance between the corner pieces 1, the connecting rod 3 can be rotated according to the needs by using the turning handle 34 to rotate the scale plate 31 of the required specified scale unit to the top. When the scale plate 31 is located at the top, the limit bar 33 will continue to be stuck on the inner wall of the limit plate 22. At this time, the value on the scale plate 31 is checked through the positioning hole 41. The distance between the corner pieces 1 can be determined by using the positioning hole 41 to cooperate with the scale plate 31.

[0038] When the distance between the corner pieces 1 is determined, the back of the blade 12 is clamped in the clamping groove 11 of the corner piece 1, and then the leather sample cutting work can be carried out;

[0039] When cutting the leather sample, the squeezing plate 52 will first rest against the surface of the leather sample, and then the blade 12 will be pressed down. At this time, since the squeezing plate 52 is limited by the leather sample, it will compress the spring 51, causing the spring 51 to contract. At this time, the squeezing plate 52 will limit and fix the leather sample, making the blade 12 more stable and accurate during the cutting process. When the blade 12 completes the cutting, it begins to rise. When the blade 12 is pulled out of the leather sample, the pressure on the spring 51 disappears, and it begins to rebound, driving the squeezing plate 52 to move downward. At this time, the squeezing plate 52 can squeeze and remove the leather sample stuck to the side wall of the blade 12.

[0040] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
