Description

Technical Field

[0001] The invention relates to the technical field of spring machines, and in particular to a full-automatic riveting integrated spring machine. Background Art

[0002] The riveting integrated spring machine is a device specially used for spring riveting. It integrates the functions of riveting and spring manufacturing into one, improving production efficiency and processing accuracy.

[0003] The working principle of the spring machine is mainly to wind the steel wire into a preset shape through the deformation of the steel wire and the cooperation of the spring mold, so as to manufacture various types of springs. The specific process is: first, the machine body fixes a section of the spring steel wire at the tail of the spring machine, and then the drive is driven to press the steel wire into the forming mold at a certain speed and force to deform the steel wire. In this process, the spring machine uses one or several pairs of rollers to press the steel wire and rotate it, pushing the steel wire forward, and relying on the limiting and guiding function of the upper and lower diameter rods to shape the steel wire. In this process, the forming mold will rub against the steel wire, so that the temperature of the forming mold and the steel wire gradually increases. With the increase in temperature, the material properties of the steel wire may change, such as the decrease of hardness, strength, toughness and other indicators, thereby affecting the quality and service life of the spring. In addition, high temperature will accelerate the wear of the mold, shorten the service life of the mold, and increase production costs. Summary of the invention

Under the action of the cooling structure, the sliding plug 72 can supply low-temperature gas into the nozzle 6, so that the nozzle 6 sprays low-temperature gas, and the low-temperature gas sprayed by the nozzle 6 can cool the steel wire and the shaping mold in the manufacturing process to avoid overheating of the shaping mold and the steel wire;

[0053] The frame 1 is provided with a moving structure, which includes: a side plate 91 fixed to the side of the frame 1; two brackets 92, one of which is fixed to the top surface of the frame 1, and the other is fixed to the top surface of the side plate 91, and the two brackets 92 are arranged opposite to each other; a reciprocating screw rod 93, which is rotatably installed between the two brackets 92; a transmission shaft 94, which is fixed to one end of the reciprocating screw rod 93; two bevel gears 95, one of which is fixedly sleeved on the axle of the feeding module 2, and the other is fixedly sleeved on the transmission shaft 94, and the two bevel gears 95 are meshed with each other; a moving plate 96, which is threadedly sleeved on the reciprocating screw rod 93, and the moving plate 96 The bottom surface and the top surface of the side plate 91 fit each other; a fixed rod 97, one end of which is fixedly connected to the movable plate 96, and the other end extends to the interior of the cooling box 81, and one end of the fixed rod 97 located inside the cooling box 81 is fixedly connected to the mounting plate 83, and the reciprocating screw 93 can drive the movable plate 96 to reciprocate between the two brackets 92 when rotating, and the movable plate 96 can drive the mounting plate 83 to move through the fixed rod 97 when moving, so that the mounting plate 83 and the semiconductor refrigeration plate 84 reciprocate inside the cooling box 81, and the semiconductor refrigeration plate 84 can comprehensively cool the coolant in the cooling box 81 when reciprocating, so that the coolant can be comprehensively cooled.

[0054] Working principle of the present invention:

[0055] When the fully automatic riveting integrated spring machine proposed by the present invention is in use, the spring machine uses a number of shaping structures to press the steel wire and rotate it, so as to push the steel wire to move forward, and relies on the limiting and guiding functions of the upper and lower circle diameter rods to shape the steel wire. The steel wire continuously moves forward in the respective slide grooves of the upper and lower circle diameter rods. By controlling the positions of the upper and lower circle diameter rods, the size of the spring circle diameter can be controlled. At the same time, the pitch rod moves vertically to the paper surface, and its function is to make the wound steel wire form a thread lead angle. By controlling and adjusting the position of the pitch rod, the size of the spring pitch can be controlled. When the winding is completed, the steel wire is cut by a cutter, and the mandrel is used as a cutter to cut. The steel wire is wound into a preset shape with the help of the machine body, so as to manufacture a spring. In the process of manufacturing the spring, a plurality of movable seats 5 move on a plurality of fixed seats 4. The movable seats 5 can press the top plate 74 during the movement. When the top plate 74 is pressed by the movable seats 5, the top plate 74 can move and drive the sliding plug 72 to move through the connecting rod 73. When the movable seat 5 is separated from the top plate 74, the sliding plug 72 will be reset under the elastic force of the spring 75. Therefore, in the process of manufacturing the spring, the sliding plug 72 can move back and forth inside the sealing tube 71.

[0056] Two mounting tubes 76 are connected to the sealing cylinder 71, and both mounting tubes 76 are equipped with one-way valves 77. One of the one-way valves 77 restricts the airflow to only enter the interior of the sealing cylinder 71, and the other one-way valve 77 restricts the airflow to only flow out of the interior of the sealing cylinder 71. Therefore, when the sliding plug 72 moves toward one end of the sealing cylinder 71, the sliding plug 72 can perform a suction action, and when the sliding plug 72 moves toward the other end of the sealing cylinder 71, the sliding plug 72 can perform a venting action. Based on the above process, when the moving seat 5 squeezes the top plate 74, the sliding plug 72 can push the sealing cylinder The gas in 71 is pressed into the nozzle 6, so that the gas is ejected through the nozzle 6. When the sliding plug 72 is reset under the elastic force of the spring 75, the sliding plug 72 can perform a pumping action and extract the gas from the cooling pipe 82. The cooling pipe 82 is immersed in the coolant, and the coolant can cool the gas in the cooling pipe 82. In summary, under the action of the cooling structure, the sliding plug 72 can supply low-temperature gas into the nozzle 6, so that the nozzle 6 ejects low-temperature gas. The low-temperature gas ejected from the nozzle 6 can cool the steel wire and the shaping mold in the manufacturing process to prevent the shaping mold and the steel wire from overheating;

[0057] The interior of the cooling box 81 is provided with a semiconductor refrigeration sheet 84. When the semiconductor refrigeration sheet 84 is powered on, it can cool the coolant in the cooling box 81. The low-temperature coolant can ensure the cooling effect on the gas. In addition, the feeding module 2 is responsible for conveying the steel wire raw material during the spring manufacturing process. During the feeding process, the feeding wheel on the feeding module 2 can rotate, and the wheel axle thereon can drive the transmission shaft 94 to rotate through two mutually meshing bevel gears 95. When the transmission shaft 94 rotates, it can drive the reciprocating screw rod 93 to rotate. Due to the bottom surface of the movable plate 96 The movable plate 96 is in contact with the top surface of the side plate 91, so it cannot rotate with the reciprocating screw 93. Therefore, the reciprocating screw 93 can drive the movable plate 96 to reciprocate between the two brackets 92 when rotating. When the movable plate 96 moves, it can drive the mounting plate 83 to move through the fixed rod 97, so that the mounting plate 83 and the semiconductor refrigeration plate 84 can reciprocate inside the cooling box 81. When reciprocating, the semiconductor refrigeration plate 84 can comprehensively cool the coolant in the cooling box 81, so that the coolant can be comprehensively cooled.

[0058] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
