Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold base for an electric screw press. Background Art

[0002] In the forging industry, the die holder of an electric screw press is a core component that carries the die and transmits forging energy, and its performance directly affects the product production range, forging accuracy and service life of the equipment. With the continuous increasing market demand for product variety diversification and large size specifications, the existing 25,000-ton press die base has gradually exposed many technical defects that cannot be ignored, and can no longer meet the demand for efficient and stable production;

[0003] First, the existing die base can only be well adapted to the production of blade products and crankshafts with a length ≤ 2800mm. When facing products such as large crankshafts with a length > 2800mm, limited by its own structural size design, it cannot provide sufficient installation space and stable support, resulting in obviously insufficient production capacity for large-size products, which restricts the enterprise's expansion into the market of high value-added large products;

[0004] Secondly, the maximum installation size of the die matched with the old die base is only 2000×850, and this size parameter imposes a hard constraint on the specifications of producible products. Against the background of the growing market demand for products with larger sizes and more complex structures, the excessively small die installation scale makes it difficult for enterprises to develop and produce products beyond this size range, which misses market opportunities and reduces the market competitiveness of the equipment;

[0005] Finally, the existing lower die base adopts an open top structure design. When producing twisted blade products, the horizontal component force generated during forging lacks an effective dispersion and restraint mechanism. This results in an obvious trend of the lower die base opening to both sides under the action of horizontal component force. After long-term exposure to such stress, the bottom of the lower die base is prone to cracking, which not only affects the stability of the forging process and product accuracy, but also requires frequent maintenance or even replacement, increasing production costs and reducing production efficiency. Contents of the Utility Model

[0006] The purpose of the utility model is to provide a die holder for an electric screw press, and the use of this device for working can solve the above problems.

[0007] In order to solve the above technical problems, the utility model provides the following technical solution: a die holder for an electric screw press, comprising a lower die holder main body and an upper die holder main body, the upper die holder main body is arranged above the lower die holder main body, lower die holder stoppers are fixed at the front and rear ends of the lower die holder main body, lower die holder reinforcing ribs are arranged above the lower die holder stoppers, and upper die holder stoppers are fixed at the front and rear ends of the upper die holder main body.

[0008] Preferably, there are two lower mold base blocks, which are symmetrical at both ends of the centerline of the lower mold base body.

[0009] Preferably, the lower mold base stop block and the upper mold base stop block have the same shape and size, and the top surface of the lower mold base stop block and the bottom surface of the upper mold base stop block are the same and their positions correspond.

[0010] Preferably, there are two lower mold base tie rods, which are symmetrical at both ends of the centerline of the lower mold base body.

[0011] Preferably, the two sides of the lower mold base tie rod are connected to the two sides of both ends of the lower mold base body, and the inner wall of the lower mold base tie rod is in contact with the outer wall of the upper mold base stop.

[0012] Preferably, there are two upper mold base blocks, which are symmetrical at both ends of the center line of the upper mold base body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The electric screw press die holder provided by this utility model increases the contact area with the die insert through the upper die holder stop and the lower die holder stop, so that the impact energy in the forging process is evenly distributed and transmitted through the large contact area, avoiding local stress concentration, reducing structural damage and wear of the die holder and insert caused by excessive local stress, ensuring the structural stability in the forging process, extending the service life of the die and die holder, and reducing the probability of equipment failure.

[0015] 2. The electric screw press die holder provided by this utility model adds a lower die holder tie rod to rigidly connect the two sides of the lower die holder, constructing a horizontal force distribution path, actively bearing the horizontal force generated by blade forging, suppressing the lateral opening tendency of the lower die holder body, solving the risk of the lower die holder body opening to both sides and cracking at the bottom when there is no tie rod, making the stress state of the lower die holder more reasonable, significantly improving the working stability of the lower die holder under complex stress conditions, extending the service life of the lower die holder body, and reducing maintenance and replacement costs.

[0016] 3. The electric screw press die holder provided by this utility model integrates the "stop block + insert" expansion mechanism and the optimized structure of the lower die holder tie rod, realizing the compatible production of multiple specifications of products, reducing equipment investment, and reducing the risk of production interruption due to structural damage. It eliminates the need for frequent die holder replacement or downtime maintenance, ensuring production continuity, reducing the total life cycle cost of equipment, improving production efficiency and equipment utilization, and achieving a dual improvement in the die holder's applicability and economic practicality, creating greater benefits for enterprises.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figure 1 As shown, the present invention provides an electric screw press die holder, including a lower die holder body 1 and an upper die holder body 2. The upper die holder body 2 is arranged above the lower die holder body 1. Lower die holder blocks 3 are fixed at the front and rear ends of the lower die holder body 1. Lower die holder tie rods 4 are arranged above the lower die holder blocks 3. Upper die holder blocks 5 are fixed at the front and rear ends of the upper die holder body 2.

[0022] There are two lower mold base stops 3, which are symmetrical at both ends of the center line of the lower mold base body 1.

[0023] The lower mold base stop 3 and the upper mold base stop 5 have the same shape and size. The top surface of the lower mold base stop 3 and the bottom surface of the upper mold base stop 5 are the same and their positions correspond.

[0024] There are two lower mold base tie rods 4, which are symmetrical at both ends of the center line of the lower mold base body 1.

[0025] The two sides of the lower mold base tie rod 4 are connected to the two sides of both ends of the lower mold base body 1, and the inner wall of the lower mold base tie rod 4 is in contact with the outer wall of the upper mold base stop block 5.

[0026] There are two upper mold base stops 5, which are symmetrical at both ends of the center line of the upper mold base body 2.

[0027] Specifically, the dimensions of the upper and lower mold base mounting parts are 2200×950;

[0028] When the size of the product exceeds the mold installation size, the mold can be lengthened by adding inserts. The insert added to the upper mold is in contact with the upper mold base stop 5, and the insert added to the lower mold is in contact with the lower mold base stop 3, so as to withstand the impact energy during the forging process.

[0029] When producing blade products, because the blade has a twist angle, a horizontal component force will be generated during the forging process. Without the lower die holder tie rod 4, the horizontal component force will cause the lower die holder body 1 to open to both sides, and there is a risk of cracking at the bottom of the lower die holder body 1. To address this situation, the lower die holder tie rod 4 is designed to connect the two sides of the lower die holder body 1 to share the horizontal component force, thereby improving the working condition of the lower die holder body 1 and extending its service life.
