Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold steel pretreatment technology, specifically to a mold steel pretreatment device. Background Technology
[0002] Die steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. Molds are the main processing tools for manufacturing parts in industries such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the mold directly affects the quality of the pressure processing, the precision and output of the product, and the production cost. In addition to reasonable structural design and machining accuracy, the quality and service life of the mold are mainly affected by the mold material and heat treatment.
[0003] Before use, mold steel requires pretreatment through heat treatment followed by quenching to achieve the required hardness, toughness, strength, and rigidity. This step typically requires manual labor, where workers immerse the heated mold steel in quenching liquid and frequently turn it to ensure uniform quenching—a very time-consuming and labor-intensive process. To address these issues, an innovative design was developed based on the existing pretreatment equipment. Utility Model Content
[0004] The purpose of this utility model is to provide a mold steel pretreatment device to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold steel pretreatment device, including a quenching tank, a servo motor mounted on the surface of the quenching tank, a drive shaft fixed to the output end of the servo motor, an adjusting sleeve provided on the outer side of the drive shaft, a support tray fixed to the surface of the adjusting sleeve, a placement groove provided on the edge of the support tray, a closing block provided at the opening of the placement groove, a storage cavity provided inside the closing block, a locking rod provided on the inner side of the storage cavity, a tightening spring provided at one end of the locking rod located in the storage cavity, and a traction rope connected to the locking rod.
[0006] Preferably, the surface of the drive shaft is provided with an adjustment groove.
[0007] Preferably, an adjusting block is fixed on the inner wall of the adjusting sleeve, and the adjusting block is located in the adjusting groove.
[0008] Preferably, the support tray is slidably connected to the drive shaft via an adjusting sleeve, and there are two support trays symmetrically distributed on the drive shaft.
[0009] Preferably, the placement slots are distributed at equal angles along the edge of the tray.
[0010] Preferably, a locking hole is provided on the inner wall of the placement groove, and one end of the locking rod is located in the locking hole.
[0011] Preferably, the locking rod forms a telescopic structure with the storage cavity via a tightening spring.
[0012] Preferably, the end of the traction rope away from the locking bar is connected to a pull ring.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this mold steel pretreatment device, the two ends of the mold steel are placed in the placement grooves on the edges of different support trays. The sealing block is installed at the opening of the placement groove by a locking rod to seal it. When the servo motor drives the drive shaft to rotate, the drive shaft drives the mold steel to rotate around the drive shaft through the support tray, which is conducive to the mold steel being immersed in the quenching liquid in the quenching tank for quenching. At the same time, the support tray can adjust the spacing on the drive shaft by adjusting the sleeve, which is conducive to adjustment according to the length of the mold steel.

[0020] 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.
[0021] Please see Figures 1-5This utility model provides a technical solution: a mold steel pretreatment device, including a quenching tank 1, a servo motor 2 mounted on the surface of the quenching tank 1, a drive shaft 3 fixed at the output end of the servo motor 2, an adjusting sleeve 5 on the outer side of the drive shaft 3, a support tray 7 fixed on the surface of the adjusting sleeve 5, a placement groove 8 opened on the edge of the support tray 7, a closing block 9 opened at the opening of the placement groove 8, a storage cavity 10 opened inside the closing block 9, a locking rod 11 opened on the inner side of the storage cavity 10, a tightening spring 13 opened at one end of the locking rod 11 located in the storage cavity 10, and a traction rope 14 connected to the locking rod 11.
[0022] An adjustment groove 4 is provided on the surface of the drive shaft 3, and an adjustment block 6 is fixed on the inner wall of the adjustment sleeve 5. The adjustment block 6 is located in the adjustment groove 4, which facilitates the adjustment sleeve 5 to slide and adjust its displacement on the outside of the drive shaft 3 through the adjustment block 6 and the adjustment groove 4.
[0023] The support plate 7 is slidably connected to the drive shaft 3 through the adjusting sleeve 5. There are two support plates 7 symmetrically distributed on the drive shaft 3. The support plate 7 can stably support both ends of the mold steel.
[0024] The placement slots 8 are distributed at equal angles on the edge of the support tray 7, which is conducive to placing multiple mold steels in different placement slots 8, facilitating subsequent synchronous quenching and improving quenching efficiency.
[0025] A locking hole 12 is provided on the inner wall of the placement groove 8. One end of the locking rod 11 is located in the locking hole 12. The locking rod 11 forms a telescopic structure with the storage cavity 10 through the tightening spring 13. The tightening spring 13 can push the locking rod 11 into the locking hole 12, which is beneficial for the stable installation of the sealing block 9 at the opening of the placement groove 8.
[0026] The end of the traction rope 14 away from the locking lever 11 is connected to a pull ring, which makes it easy to pull the traction rope 14.
[0027] Working principle: According to Figures 1-5As shown, firstly, based on the length of the mold steel, the support tray 7 is pushed to adjust its displacement on the drive shaft 3 via the adjusting sleeve 5. At this time, the adjusting sleeve 5 slides on the drive shaft 3 through the adjusting block 6 and the adjusting groove 4 until the appropriate distance is adjusted between the two support trays 7. Then, the locking bolts on the adjusting sleeve 5 are tightened for fixation. Next, the mold steel to be quenched is hoisted and placed into the quenching tank 1, so that both ends of the mold steel are located in the placement grooves 8 on the edges of different support trays 7. Then, the traction rope 14 is pulled outward towards the closing block 9, at which point the traction rope 14 is pulled and locked. The rod 11 is retracted into the storage cavity 10, and then the sealing block 9 is inserted into the opening of the placement slot 8, so that the locking rod 11 is aligned with the locking hole 12. At this time, the pulling traction rope 14 is released, so the tightening spring 13 pushes the locking rod 11 out of the storage cavity 10 until the locking rod 11 is inserted into the locking hole 12. At this time, the sealing block 9 is stably installed at the opening of the placement slot 8. Then, the servo motor 2 is started to drive the drive shaft 3 to rotate. The drive shaft 3 drives the mold steel to move around the drive shaft 3 through the bearing tray 7, so that the mold steel can be quenched in the quenching liquid in the quenching tank 1.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
