Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of extrusion dies, in particular to a sleeve-type cold extrusion die. Background Art
[0002] Cold extrusion dies are tools used to press metal blanks into the desired shape at room temperature or slightly heated conditions. During the cold extrusion process, the metal blank is placed between dies and high pressure is applied to deform it under the shape of the die to eventually form the desired part or product. The nested cold extrusion die consists of a main module and several auxiliary modules, which can be nested with each other to meet different processing requirements. By using multi-part dies, the deformation of the metal blank can be more accurately controlled to obtain high-precision parts. The nested die can achieve complex shapes and internal structures by combining different modules to meet various engineering needs.
[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology:
[0004] (1) The sleeve-type cold extrusion die is usually manufactured according to specific design requirements and process flow. Once the design of the die is determined, it is difficult to replace or modify it, which may limit the flexibility and diversity of the production line. New parts need to be processed or process parameters need to be adjusted. The sleeve-type die may not be able to adapt to these changes, resulting in reduced production efficiency or requiring additional time and resources to adapt to new production requirements. With the continuous development of science and technology, new processing technologies or more efficient die designs may emerge, but due to the specific structure and design of the sleeve-type cold extrusion die, it may be difficult to update or upgrade the technology, thereby limiting the development and improvement of the production line.
[0005] (2) After each processing is completed, the mold needs to be manually pushed out of the workpiece, which will increase the production cycle, reduce production efficiency, increase labor costs, and may require additional training and supervision to ensure the correctness and safety of the operation. The manual mold push process takes extra time, which will increase the downtime of the production line and affect the overall production efficiency and capacity. Utility Model Content
[0006] In view of the shortcomings of the prior art, the utility model provides a sleeve-type cold extrusion die, which has the advantages of being able to replace different dies and automatically eject parts, solving the problem of increased waste and loss caused by the fixed and inability to replace dies and the need to manually remove parts.
[0007] The utility model provides the following technical scheme: a sleeve-type cold extrusion die, comprising a main bottom plate, the top end of the main bottom plate is fixedly connected to a limiting column, the outer wall of the limiting column is movably sleeved with a bottom die, the bottom end of the bottom die is provided with a circular groove, the bottom end of the main bottom plate is provided with a slot hole, and the circular groove is consistent in position with the groove, and one group of fixing parts one is fixedly connected inside, one end of a spring two is fixedly connected inside the fixing part one, the other end of the spring two is fixedly connected to a connecting ring, the bottom end of the connecting ring is fixedly connected to a fixing part two, the inside of the connecting ring is fixedly connected to a connecting rod, the outer wall of the connecting rod is movably sleeved with four groups of support blocks, and the four groups of support blocks are arranged in a circular array with the fixing part two as the center.

[0009] Preferably, the outer wall of the hydraulic telescopic rod 1 is fixedly connected to a column, and the bottom end of the column is fixedly connected to a main bottom plate.
[0010] Preferably, a top mold is provided at the bottom end of the top plate, a limiting groove is provided inside the top mold, and the inner wall of the limiting groove fits with the outer wall of the limiting column.
[0011] Preferably, the bottom end of the main bottom plate is fixedly connected to a second hydraulic telescopic rod, a model groove is provided inside the bottom mold, and the bottom end of the model groove is aligned with the top end of the second hydraulic telescopic rod.
[0012] Preferably, four groups of legs are fixedly connected to the bottom end of the main bottom plate, and the four groups of legs are in a square array.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. This type of sleeve-type cold extrusion mold, by pushing the fixing part 2, makes the top support block rotate with the connecting rod as the center of the circle, so that it is flush with the outer wall of the fixing part 1. At this time, the bottom mold is moved upward or the top mold is moved downward, and a new mold can be replaced. After the new mold is aligned and placed, the pressure on the fixing part 2 is released, and the elastic potential energy of the spring 2 pushes the bottom connecting ring to move to one end inside the fixing part 1, thereby pushing the support block to rotate outward with the connecting rod as the center of the circle, so that the bottom of the support block is clamped with the inner wall of the bottom mold, so that the bottom mold is fixed to the upper end of the total bottom plate. The replacement of the top plate and the top mold is similar, so that different molds can be replaced. Different mold parts can be quickly replaced as needed to meet the different parts processing requirements on the production line, thereby improving the flexibility of production. Different mold parts can realize the processing of parts of different shapes and sizes, so that the production line can respond to diverse market needs and improve the diversity of products. There is no need to design and manufacture separate molds for each different part, but different parts can be processed by replacing mold parts, saving manufacturing costs and time.
[0015] 2. This type of sleeve-type cold extrusion mold drives the top plate to move downward when the hydraulic telescopic rod 1 is extended and retracted toward the lower end, so that the bottom bevel of the push block 1 on the side and the bottom bevel of the sliding bottom plate slide inside the bottom mold, so that when the top mold moves to the lower end, there is a baffle at the bottom to complete the pressing of the mold. When the mold is pressed, the elastic potential energy of the spring 1 pushes the sliding bottom plate to move outward, so that the slot at the bottom of the total bottom plate and the model slot at the bottom of the bottom mold are connected. At this time, the hydraulic telescopic rod 2 is started to push the parts inside the bottom mold to the inside of the bottom mold for the convenience of the next step of processing. Automatic part removal means that no manual intervention or operation is required, and production can be carried out continuously, thereby greatly improving production efficiency. Workers can focus on monitoring the production process without spending time and energy on manually removing each part. The automated production process reduces the demand for manpower, thereby reducing labor costs. Compared with manual operation, automatic part removal can also reduce the risk of personal injury and improve work safety. BRIEF DESCRIPTION OF THE DRAWINGS
