Description

Technical Field

[0001] This utility model relates to the field of crimping machine technology, and more specifically, to a hydraulic hose quick-change crimping mold assembly. Background Technology

[0002] Currently, most hydraulic hose crimping die assemblies on the market use a traditional fixed installation structure for the connection between the die and the fixed base. This structure often reveals numerous problems during long-term use. During crimping, the die is subjected to significant pressure and friction, causing the clearance between the die and the fixed base to gradually change. Consequently, after crimping, jamming can easily occur between the die and the fixed base. Once jamming occurs, technicians face significant difficulties in disassembling the die, requiring considerable time and effort, using various tools for prying, hammering, and other operations to barely remove the die from the fixed base.

[0003] This inefficient method of mold disassembly not only prolongs the downtime of production equipment, reduces production efficiency, and increases production costs, but may also damage the mold and the mounting base due to improper disassembly operations, affecting their service life and the accuracy of subsequent use.

[0004] Therefore, this application provides a quick-change crimping die assembly for hydraulic hoses to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a quick-change hydraulic hose crimping mold assembly. It can reduce jamming between the mold and the fixed seat after crimping by squeezing the mold, making the mold disassembly work more convenient and thus improving the mold replacement efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A quick-change hydraulic hose crimping die assembly includes a base, a crimping machine fixedly connected to the upper end of the base, and upper fixed seats fixedly connected to both the upper end of the base and the output end of the crimping machine. An installation groove is chiseled on the outer end of the upper fixed seat. An upper die is housed in the upper installation groove, and a lower die is housed in the lower installation groove. Two sliding grooves are chiseled on both the left and right ends of the upper fixed seat, symmetrical about the upper die. A slider is slidably connected within each sliding groove. A fixed plate is fixedly connected to the outer end of each slider. A threaded hole is chiseled on the outer end of the fixed plate, and a screw is threadedly connected within the threaded hole. A clamping push block is provided at the outer end of the screw. This assembly allows for compression of the die, reducing jamming between the die and the fixed seat after crimping, making die disassembly more convenient and improving die replacement efficiency.

[0008] As a further improvement of this utility model: the cross-sections of the groove and the slider are both set in a trapezoidal shape, and a polished layer is provided at the contact points of the groove and the slider. By setting them in a trapezoidal shape, the groove and the slider are not easily separated. By providing a polished layer, the slider can slide more smoothly in the groove.

[0009] As a further improvement of this utility model, a handle is fixedly connected to the outer end of the screw, and the surface of the handle is engraved with anti-slip texture. By setting the handle, it is more convenient for technicians to adjust the screw, thereby improving the work efficiency of technicians.

[0010] As a further embodiment of this utility model: a rotating block is fixedly connected to one end of the screw near the clamping push block, and a rotating hole is drilled at one end of the clamping push block near the screw. The rotating block and the rotating hole are rotatably connected. By setting the rotating block and the rotating hole, it is possible to prevent the clamping push block from rotating when the screw rotates, thereby allowing the clamping push block to be accurately engaged in the second mounting groove, thus locking the position of the lower mold and the slide.

[0011] As a further embodiment of this utility model: the upper end of the clamping push block is chiseled with a second mounting groove, a limit block is installed in the second mounting groove, and the upper end of the fixing plate is chiseled with a limit groove. By setting the second mounting groove, the limit block and the limit groove, it is possible to prevent the screw from rotating and causing the clamping push block to rotate with it, thereby enabling the clamping push block to move stably.

[0012] As a further improvement of this utility model: two mutually symmetrical indicator rods are fixedly connected to the inner wall of the fixing plate, and the limiting block is provided with a scale. By setting the indicator rods and the scale, the position distribution of the lower mold and the slide in the installation groove can be known. This allows technicians to easily adjust the position of the lower mold and the slide according to the position corresponding to the scale data, so that the lower mold and the slide are aligned.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. By designing the device in a trapezoidal shape, the slide groove and the slider are less likely to separate. By adding a polished layer, the slider can slide more smoothly in the slide groove. By adding a handle, it is easier for technicians to adjust the screw, thereby improving the efficiency of the technicians. By adding a rotating block and a rotating hole, it is not easy for the screw to rotate and drive the clamping push block to rotate as well. This allows the clamping push block to be accurately locked into the mounting groove, thereby locking the position of the lower mold and the slide groove.

[0015] 2. By setting up the second mounting groove, the limiting block and the limiting groove, the device can prevent the screw from rotating and causing the clamping push block to rotate. This allows the clamping push block to move stably. By setting up the indicator rod and scale, the position distribution of the lower mold and the slide in the second mounting groove can be known. This allows technicians to easily adjust the position of the lower mold and the slide according to the position corresponding to the scale data, so that the lower mold and the slide are aligned.

[0025] Please see Figures 1-4 A hydraulic hose quick-change crimping mold assembly includes a base 1, a crimping machine 2 fixedly connected to the upper end of the base 1, and an upper fixed seat 3 fixedly connected to both the upper end of the base 1 and the output end of the crimping machine 2. An installation groove 4 is chiseled on the outer end of the upper fixed seat 3. An upper mold 5 is provided in the upper installation groove 4, and a lower mold 6 is provided in the lower installation groove 4. Two sliding grooves 7 are chiseled on both the left and right ends of the upper fixed seat 3, symmetrical about the upper mold 5. A slider 8 is slidably connected within the sliding groove 7. A fixed plate 9 is fixedly connected to the outer end of the slider 8. A threaded hole 10 is chiseled on the outer end of the fixed plate 9, and a screw 11 is threadedly connected within the threaded hole 10. A clamping push block 12 is provided at the outer end of the screw 11. This assembly can reduce jamming between the mold and the fixed seat after crimping by pressing the mold, making mold disassembly more convenient and improving mold replacement efficiency.

[0026] Please see Figure 2Both the slide groove 7 and the slider 8 have trapezoidal cross sections. A polished layer is provided at the contact points between the slide groove 7 and the slider 8. By setting them into trapezoidal shapes, the slide groove 7 and the slider 8 are less likely to separate. By setting the polished layer, the slider 8 can slide more smoothly in the slide groove 7. A handle 1101 is fixedly connected to the outer end of the screw 11. The surface of the handle 1101 is engraved with anti-slip texture. By setting the handle 1101, it is more convenient for technicians to adjust the screw 11, thereby improving the work efficiency of technicians.

[0027] Please see Figures 3-4 A rotating block 1102 is fixedly connected to one end of the screw 11 near the clamping push block 12. A rotating hole 1203 is drilled at one end of the clamping push block 12 near the screw 11. The rotating block 1102 and the rotating hole 1203 are rotatably connected. By setting the rotating block 1102 and the rotating hole 1203, it is possible to prevent the screw 11 from rotating and causing the clamping push block 12 to rotate as well. This allows the clamping push block 12 to be accurately engaged in the mounting groove 4, thereby locking the positions of the lower mold 6 and the slide 7. A second mounting groove 1201 is drilled at the upper end of the clamping push block 12. A limit block 1202 is installed in the second mounting groove 1201. A fixed plate 9 is drilled at the upper end. The limiting groove 901, by setting the mounting groove 2 1201, the limiting block 1202 and the limiting groove 901, can prevent the screw 11 from rotating and causing the clamping push block 12 to rotate, so that the clamping push block 12 can move stably. Two mutually symmetrical indicator rods 902 are fixedly connected to the inner wall of the fixing plate 9. The limiting block 1202 is provided with a scale. By setting the indicator rods 902 and the scale, the position distribution of the lower mold 6 and the slide 7 in the mounting groove 1 4 can be known. This allows technicians to easily adjust the position of the lower mold 6 and the slide 7 according to the position corresponding to the scale data, so that the lower mold 6 and the slide 7 are aligned.

[0028] Working principle: When using this device, the technician rotates the screw 11 by hand, causing the screw 11 to move outward, thereby separating the clamping push block 12 from the upper fixed seat 3. Then, with the sliding action between the slide groove 7 and the slider 8, the clamping push block 12 slides downward, aligning the clamping push block 12 with the upper groove of the upper mold 5. Then, the screw 11 is rotated again, causing the clamping push block 12 to enter the upper mold 5, clamping the lower mold 6 or the slide groove 7, thus locking the position of the lower mold 6 or the slide groove 7. Disassembly is performed by reversing the above operations. Compared with the prior art, this utility model can reduce the jamming between the mold and the fixed seat after pressing by squeezing the mold, making the mold disassembly work more convenient and improving the mold replacement efficiency.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
