Description

Technical Field

[0001] This utility model belongs to the field of diameter reduction machine technology, and in particular relates to a diameter reduction machine with quick mold change. Background Technology

[0002] A diameter reduction machine is a metal processing device primarily used to reduce the diameter of pipes, bars, or wires partially or entirely through mechanical pressure to achieve precise dimensional requirements or enhance the strength of joints. Its working principle typically utilizes the strong extrusion force generated by hydraulic or mechanical transmission to cause plastic deformation of the material in a die, thereby achieving outer diameter reduction, wall thickness adjustment, or end shaping. Diameter reduction machines are widely used in industries such as pipe connections, machinery manufacturing, automotive parts, and hardware tools. They offer advantages such as ease of operation, high efficiency, stable precision, and no cutting wear, effectively improving workpiece assembly performance and overall structural strength.

[0003] Existing diameter reduction machines lack the capability for rapid die changeover in practical use. Each die change requires significant time and manpower for tedious disassembly and installation, leading to prolonged equipment downtime, severely impacting production efficiency, and making it difficult to meet the demands of urgent orders or rapid product changeovers. Furthermore, the complex changeover process increases the difficulty and intensity of manual operation, easily resulting in improper installation and affecting the accuracy and quality stability of the diameter reduction process. In addition, frequent and inefficient die changes increase production costs, reduce overall production efficiency and market competitiveness, and are detrimental to operator use. Therefore, we propose a rapid die changeover diameter reduction machine. Utility Model Content

[0004] The purpose of this invention is to provide a quick-change die reduction machine to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a quick-change die reduction machine, including a die reduction machine body and a die body. A power box is fixedly installed on the die reduction machine body, and a circular shell is fixedly connected to one side of the power box. The die body is disposed on one side of the circular shell. The motor is located inside the power box, and the output end of the motor extends through the interior of the circular shell. The exterior of the mold body has six circumferentially distributed slots, and one side of the circular shell has six circumferentially distributed inserts. A movable component is disposed inside the circular shell and is used to drive six insert blocks to move simultaneously.

[0006] In this technical solution, when a mold needs to be changed, the motor in the power box is first started. The motor output drives the rotating shaft to rotate, which in turn drives the turntable to rotate synchronously. Through the set moving component, the connecting block can move the insert block closer to the mold body. Finally, the insert block is inserted into the slot of the new mold body, realizing the quick replacement of the mold. With the above structure, the mold body can be quickly replaced. The replacement operation is simple, takes less time, and does not require complicated tools or long-term adjustments, which greatly improves the mold changing efficiency and reduces equipment downtime. At the same time, by quickly changing molds of different specifications, production needs can be quickly switched, adapting to multi-variety, small-batch processing scenarios, significantly enhancing the flexibility and response speed of the production line, and thus facilitating the use by the staff.

[0007] By sliding the slider inside the groove, the connecting block becomes more stable when moving. By sliding the connecting block inside the through groove, the connecting block can move outside the round shell. By inserting the insert block into the slot, the installation firmness of the mold body is improved.

[0008] In the above technical solution, a support plate is further fixedly connected to one side of the inner wall of the power box, and the motor is fixedly mounted on the support plate.

[0009] In this technical solution, the support plate ensures that the motor will not idle during operation.

[0010] In the above technical solution, further, a disc is fixedly connected to the inner wall of the circular shell near the power box, and six circumferentially distributed sliding grooves are opened on one side of the disc, with sliders slidably installed inside each of the six sliding grooves.

[0011] In this technical solution, the slider is slidably installed inside the groove, which makes the slider more stable when moving.

[0012] In the above technical solution, the moving component further includes a turntable, which is fixedly connected to a rotating shaft. The turntable has six circumferentially distributed arc-shaped grooves on its outer side. Each of the six sliders has a pin on one side, and the six pins are respectively disposed inside the six arc-shaped grooves.

[0013] In this technical solution, the arc groove on the turntable pushes the slider to slide in the groove of the disc through the pin shaft. The slider drives the insert block to move away from the mold body through the connecting block along the through groove of the shell.

[0014] In the above technical solution, furthermore, each of the six sliders is fixedly connected to one side of a connecting block, and the six connecting blocks are fixedly connected to the six insert blocks respectively.

[0015] In this technical solution, the insert block and the slider can be connected by the set connecting block.

[0016] In the above technical solution, further, six circumferentially distributed through slots are provided on one side of the circular shell, and the six connecting blocks are respectively slidably installed inside the six through slots.

[0017] In this technical solution, the connecting block can move outside the circular shell by sliding inside the through groove.

[0018] In the above technical solution, the plug is further adapted to the slot, and the plug can be movably inserted into the inside of the slot.

[0019] In this technical solution, the installation stability of the mold body can be improved by inserting the plug into the inside of the slot.

[0020] The beneficial effects of this utility model are: 1. When a mold needs to be changed, first start the motor in the power box. The motor output drives the rotating shaft to rotate, which in turn drives the turntable to rotate synchronously. Through the set moving component, the connecting block can move the insert block closer to the mold body. Finally, the insert block is inserted into the slot of the new mold body, realizing the quick replacement of the mold. With the above structure, the mold body can be quickly replaced. The replacement operation is simple, takes less time, and does not require complicated tools or long-term adjustments, which greatly improves the mold changing efficiency and reduces equipment downtime. At the same time, by quickly changing molds of different specifications, production needs can be quickly switched, adapting to multi-variety, small-batch processing scenarios, significantly enhancing the flexibility and response speed of the production line, and thus facilitating the use by the staff.

[0021] 2. By sliding the slider inside the groove, the connecting block can be made more stable when moving. By sliding the connecting block inside the through groove, the connecting block can be moved outside the round shell. By inserting the insert block into the slot, the installation firmness of the mold body can be improved. Attached Figure Description
