Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a four-column hydraulic cutting machine. Background Art

[0002] Cutting is a critical production process in numerous material processing industries, including leather, textiles, rubber, and plastics. Hydraulic cutting machines have emerged as efficient and precise cutting equipment. They can cut large-format raw materials into parts of specific shapes and sizes based on the characteristics and processing requirements of different materials, meeting the needs of subsequent production processes such as sewing, molding, and assembly. These machines are widely used in manufacturing industries such as footwear, luggage, clothing, automotive interiors, and sporting goods, playing a vital role in improving production efficiency, ensuring product quality, and reducing production costs, driving the entire material processing industry towards automation, efficiency, and refinement.

[0003] Traditional hydraulic cutting machines mostly adopt a relatively fixed cutting mode in their structural design. Generally, the hydraulic system drives the press plate to press on the object, so that the blade above the cutting die cuts the object. The principle is to use the hydraulic pump to transport hydraulic oil into the hydraulic cylinder, so that the piston of the hydraulic cylinder generates downward pressure, thereby cutting the material.

[0004] However, traditional hydraulic cutting machines often require manual labor to move the materials to a fixed position under the cutter die when loading and unloading. After the cutting is completed, the cut products and waste materials are taken out. It is difficult to achieve convenient movement to assist in loading and unloading operations. In the actual production process, since the position of the cutter die is relatively fixed, workers need to operate in a limited space when loading and unloading. This not only increases labor intensity, but also easily leads to inaccurate material placement or damage to the products when taking out the cut products due to inconvenient operation, thereby affecting production efficiency and product quality. For this reason, a four-column hydraulic cutting machine is proposed to solve the above problems. Utility Model Content

[0030] With reference to Figure 1 and Figure 2 An embodiment provided by the utility model: four-column oil hydraulic cutting machine, including frame 1, frame 1 is the basic frame of entire oil hydraulic cutting machine, adopts high-strength steel material, has good pressure resistance and stability, frame 1 top is fixedly connected with hydraulic cylinder 2, hydraulic cylinder 2 output end is fixedly connected with pressure table 4, under the action of hydraulic cylinder 2, along four support columns 3 direction moves, hydraulic cylinder 2 top is fixedly connected with four rectangular array support columns 3, pressure table 4 is slidably connected in four support columns 3 outer wall, frame 1 one side is provided with support assembly;

[0031] The support assembly comprises a support frame 5 and a guide column 7, the support frame 5 is fixedly connected to one side of the rack 1 to ensure the stability of the whole structure, the guide column 7 is fixedly connected to one side of the rack 1 to support and guide the sliding of the cutter die 6 on the top of the rack 1, the cutter die 6 is slidably connected to the top of the support frame 5, the cutter die 6 is slidably connected to the top of the rack 1, the cutter die 6 is fixedly connected with an axle seat 8 at the bottom, so that the cutter die 6 can slide smoothly on the top of the rack 1, the axle seat 8 is slidably connected to the outer wall of the guide column 7, the cutter die 6 is fixedly connected with a handle 9 on one side, which is convenient for the operator to manually adjust, and the cutter die 6 is provided with a connecting assembly at the bottom.

[0032] Specifically, when using the oil hydraulic cutting machine, first, the article to be cut is placed above the cutter die 6, then the output end of the hydraulic cylinder 2 drives the pressure table 4 to slide along the outer wall of the support column 3, so that the pressure table 4 is accurately pressed above the article, and under the action of the support column 3, the pressure table 4 is tightly attached to the surface of the article, ensuring the positioning accuracy of the article during cutting. At this time, the article is quickly and uniformly cut by the blade on the cutter die 6. After cutting is completed, the operator only needs to pull the handle 9 to move the cutter die 6 connected thereto. When pulling the handle 9, the cutter die 6 will drive the axle seat 8 to slide along the outer wall of the guide column 7 due to the design of the axle seat 8. During the pulling process, the cutter die 6 is extracted from between the rack 1 and the pressure table 4 through the action of the axle seat 8, successfully completing the feeding and discharging process and improving the work efficiency.

[0033] Referring to Figure 2-Figure 5 , the connecting assembly comprises a clamping block 10 fixedly connected to the bottom of the cutter die 6, a clamping groove 11 is formed in the clamping block 10, which is used to cooperate with the fixed assembly on one side of the rack 1, a fixed block 12 is fixedly connected to one side of the rack 1, a fixed frame 14 is fixedly connected to one side of the fixed block 12, a sliding groove 13 is formed in the fixed block 12, the sliding groove 13 provides a guide for the clamping block 10, the clamping block 10 is slidably connected in the sliding groove 13, a connecting frame 19 is fixedly connected to one side of the fixed block 12, the fixed frame 14 and the connecting frame 19 are both fixedly connected with fixed columns 15, one outer wall of the fixed columns 15 is slidably connected with a clamping bead 17, the other outer wall of the fixed columns 15 is slidably connected with a clamping bead 18, the clamping bead 17 and the clamping bead 18 are slidably fitted in the clamping groove 11 to ensure that the cutter die 6 remains in a fixed state during cutting, the outer walls of the two fixed columns 15 are both sleeved with springs 16, one end of one spring 16 is fixedly connected to the clamping bead 17 and the other end is fixedly connected to the inside of the fixed frame 14, the other end of the other spring 16 is fixedly connected to the connecting frame 19 and the clamping bead 18, which can provide a moderate restoring force when the clamping block 10 slides, and the clamping bead 17 and the clamping bead 18 are both slidably connected in the clamping groove 11.

[0034] Specifically, in the process of pushing the cutting die 6 between the frame 1 and the pressing table 4, when the cutting die 6 is pushed in, the card block 10 will contact the card bead 1 17 and the card bead 2 18 on one side of the frame 1. When the card bead 17 and the card bead 2 18 are squeezed by the card block 10, they slide toward the inside of the fixed frame 14 and the connecting frame 19. When the card bead 17 and the card bead 2 18 are pressed inward, they will correspondingly compress the spring 16 connected therein. When the card bead 17 and the card bead 2 18 are compressed, the card block 10 slides into the inside of the slide groove 13 and rebounds through the elastic force of the spring 16, driving the card bead 17 and the card bead 2 18 to reset. At this time, the card bead 17 and the card bead 2 18 will be stuck in the card groove 11 at the bottom of the card block 10, thereby fixing the cutting die 6 in place, ensuring its stability and accurate positioning, and avoiding errors and instability during operation.

[0035] Working principle: When using the hydraulic cutting machine, first place the object to be cut above the cutting die 6, then drive the pressing platform 4 to slide on the outer wall of the support column 3 through the output end of the hydraulic cylinder 2, so that the pressing platform 4 is pressed above the object, and then the object is cut by the blade above the cutting die 6. After the cutting is completed, just pull the handle 9 to drive the cutting die 6 connected to one side to move, and the cutting die 6 is driven by the force to drive the shaft seat 8 connected to the bottom to move, so that the shaft seat 8 slides along the outer wall of the guide column 7, and then the cutting die 6 and the object above it are pulled out from between the frame 1 and the pressing platform 4 for loading and unloading, thereby achieving the effect that the cutting die 6 can be moved to facilitate loading and unloading, and at the same time When the cutting die 6 is pushed between the frame 1 and the pressing table 4, the block 10 at the bottom of the cutting die 6 will contact the card bead 1 17 and the card bead 2 18 on one side of the frame 1, so that the card bead 17 and the card bead 2 18 are squeezed and slide toward the inside of the fixed frame 14 and the connecting frame 19 respectively. At the same time, the card bead 17 and the card bead 2 18 will respectively squeeze the spring 16 connected to them to shrink. At this time, the block 10 slides into the inside of the slide groove 13, and the spring 16 unloads the force and rebounds, thereby driving the card bead 17 and the card bead 2 18 to reset, so that they are stuck in the card groove 11 inside the block 10 to fix it, thereby achieving the effect of effectively and quickly positioning the cutting die 6.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
