Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a multifunctional rubber cutting device. Background Art

[0002] Rubber cutting refers to the process of cutting rubber materials into specific sizes and shapes. This is a very important step in the production of rubber products because it directly affects the quality and efficiency of subsequent processing.

[0003] At present, the traditional method of cutting rubber is to use a knife with a sharp blade to cut the rubber material by applying a large pressure. However, due to the elasticity of rubber, when the knife applies cutting force when cutting rubber, the rubber will be compressed or stretched, and once the cutting is completed, the rubber will recover some of its elastic deformation, resulting in the actual size after cutting not matching the expected size. For example, when cutting rubber strips for seals, if the size deviation is too large, it will affect the sealing effect.

[0004] Therefore, the present application provides a multifunctional rubber cutting device to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a multifunctional rubber cutting device to solve the problem that the cutting device in the prior art affects the cutting accuracy due to the easy rebound of rubber when cutting rubber materials.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A multifunctional rubber cutting device comprises a workbench, a frame is mounted on the upper end surface of the workbench, a hydraulic cylinder is fixed on the top upper end surface of the frame, a shaft of the hydraulic cylinder passes through the top lower end surface of the frame and is equipped with a cutter;

[0008] An abutment plate is elastically mounted on the cutter, the abutment plate is located below the cutter, a cutting notch is provided in the middle of the abutment plate for the cutter to vertically pass through, a heating channel is provided inside the abutment plate, and a heating water tank is fixed on the side of the frame, the heating water tank is connected to the heating channel.

[0009] Optionally, the frame is a "door"-shaped frame, and the two ends of the cutter are vertically slidably matched with the inner walls on both sides of the frame.

[0010] Optionally, a fixing block is fixed to the lower end of the hydraulic cylinder, a knife back is fixed to the top of the cutter, the knife back is stuck in the lower end of the fixing block, and a plurality of bolts are provided on the fixing block for fixing.

[0011] Optionally, a plurality of movable columns are symmetrically fixed to the upper end surface of the blade back, and a fixing frame is correspondingly fixed to the abutment plate, and the fixing frame is vertically slidably sleeved on the movable columns.

[0012] Optionally, a top plate is fixed to the top of the movable column, a spring is fixed to the lower end surface of the top plate, and the lower end of the spring abuts against the upper end surface of the fixing frame.

[0013] Optionally, the top plate is threadedly plugged and fixed to the top end of the movable column.

[0014] Optionally, the spring is sleeved on the movable column.

[0015] Optionally, a hose is installed on the heating water tank, and the hose is connected to the heating channel in the abutment plate to form a circulating water circuit.

[0016] Optionally, two heating channels are symmetrically arranged in the abutment plate about the cutting opening, and the two heating channels are evenly distributed inside the abutment plate.

[0017] Optionally, a heating mechanism and a water pump are provided in the heating water tank.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] In the above scheme, by elastically installing the abutment plate below the cutter, when the cutter descends to cut the rubber, the abutment plate can first be used to elastically abut and limit the upper surface of the rubber to avoid its deviation, which is conducive to ensuring cutting accuracy.

[0020] In the above scheme, thanks to the cooperation of the heating channel and the heating water tank, the abutment plate can be heated so that the cutting position can be heated when the abutment plate elastically abuts against the upper surface of the rubber. The heating can enhance the mobility of the rubber molecular segments and partially release the internal stress, thereby reducing the elasticity of the rubber, reducing the rebound during cutting, and further improving the cutting accuracy.

[0021] In summary, when cutting rubber, the device can not only limit the abutment, but also locally heat the cutting position to reduce the rebound during cutting, which can improve the cutting accuracy to a certain extent and has a good use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] As shown in Figure 1, an embodiment of the utility model provides a multifunctional rubber cutting device, including a workbench 1, a frame 2 is mounted on the upper end surface of the workbench 1, the frame 2 is a "door"-shaped frame, a hydraulic cylinder 3 is fixed to the top upper end surface of the frame 2, the shaft of the hydraulic cylinder 3 passes through the top lower end surface of the frame 2, and a cutter 4 is installed, and the two ends of the cutter 4 are vertically slidably matched with the inner walls on both sides of the frame 2, so that the hydraulic cylinder 3 can drive the cutter 4 to move up and down stably.

[0036] Specifically, as shown in Figures 2 and 3, a fixing block 301 is fixed to the lower end of the hydraulic cylinder 3, a knife back 401 is fixed to the top of the cutter 4, the knife back 401 is inserted into the lower end of the fixing block 301, and two sets of bolts are provided on the fixing block 301 to fix the cutter 4.

[0037] At the same time, the cutter 4 is elastically mounted with an abutment plate 5, which is located below the cutter 4, wherein a plurality of movable columns 402 are symmetrically fixed to the upper end surface of the knife back 401, and a fixing frame 503 is correspondingly fixed to the abutment plate 5, and the fixing frame 503 is vertically slidably sleeved on the movable column 402. A top plate 403 is fixed to the top of the movable column 402 by threaded insertion, and a spring 404 is fixed to the lower end surface of the top plate 403, and the spring 404 is sleeved on the movable column 402, and the lower end of the spring 404 abuts against the upper end surface of the fixing frame 503, so as to elastically mount the abutment plate 5 on the cutter 4, so that when the cutter 4 descends to cut the rubber, the abutment plate 5 can first elastically abut against the rubber.

[0038] As shown in FIG4 , a cutting notch 501 is provided in the middle of the abutment plate 5 for the cutter 4 to vertically pass through, a heating channel 502 is provided inside the abutment plate 5, and a heating water tank 6 is fixed to the side of the frame 2, a hose 7 is installed on the heating water tank 6, and the heating channel 502 is connected. Specifically, a hose 7 is installed on the heating water tank 6, and the hose 7 is connected to the end of the heating channel 502 in the abutment plate 5 to form a circulating water path, and two heating channels 502 are symmetrically provided in the abutment plate 5 about the cutting notch 501, and the two heating channels 502 are evenly distributed inside the abutment plate 5.

In other embodiments, the heating temperature range can also be adjusted according to the rubber material.

[0040] The working principle provided by the utility model is that the multifunctional rubber cutting device can place the rubber on the workbench 1 when in use, and then start the hydraulic cylinder 3 to drive the cutter 4 to descend. At this time, the abutment plate 5 will first abut the upper surface of the rubber to perform elastic abutment and limit it to avoid its deviation.

[0041] At the same time, the heating water tank 6 inputs hot water into the heating channel 502 through the hose 7 to heat the abutment plate 5, thereby heating the rubber cutting position to a temperature of 50-70 degrees. The heating can enhance the mobility of the rubber molecular segments and partially release the internal stress, thereby reducing the elasticity of the rubber and reducing the rebound during cutting.

[0042] Subsequently, the hydraulic cylinder 3 further drives the cutter 4 to descend, and the cutter 4 can pass through the cutting opening 501 to complete the cutting operation on the rubber.
