Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and in particular to an adjustable cutting device for irregularly shaped mold steel. Background Technology

[0002] Mold steel is the core base material for mold manufacturing and is widely used in many fields such as machinery manufacturing, automobiles, and hardware processing. Irregularly shaped mold steel is increasingly widely used due to its adaptability to complex mold forming requirements. Cutting equipment is a key piece of equipment in mold steel processing, mainly used for cutting irregularly shaped mold steel to length. Conventional mold steel cutting equipment mostly adopts a fixed clamping structure, combined with a single cutting component to complete the cutting operation, which can meet the basic cutting and processing needs of regular mold steel.

[0003] Traditional clamping structures are mostly of fixed specifications, unable to adaptively adjust to the irregular shape and different dimensions of irregularly shaped mold steel. This results in low clamping fit, making the workpiece prone to loosening and shifting, leading to decreased cutting accuracy and a high scrap rate. Furthermore, in existing cutting equipment, the workpiece is placed directly on the rollers or smooth table during feeding, resulting in constant relative sliding between the workpiece and the table. For irregularly shaped mold steel, this contact with the flat table is typically line or point contact, creating an unstable equilibrium. At the moment of stopping, the workpiece is prone to rolling or tilting, causing the actual cutting position to deviate from the theoretically set value. Therefore, this application proposes an adjustable cutting device for irregularly shaped mold steel to solve the above problems. Summary of the Invention

[0014] Compared with related technologies, the adjustable cutting device for irregular mold steel provided by the present invention has the following advantages: 1. This invention provides an adjustable cutting device for irregularly shaped mold steel. The device's locking mechanism includes a V-shaped limiting groove and independent abutment mechanisms within a moving track. The V-shaped limiting groove provides initial positioning of the bottom of the irregularly shaped mold steel. Its V-shaped structure and inner adapting groove can adapt to the bottom contours of workpieces with different diameters or widths, achieving a self-centering effect. The number of independent abutment mechanisms can be selected according to actual usage needs. Operators can arrange the required number of independent abutment mechanisms within the moving track based on the complexity of the workpiece shape. The positions of the independent abutment mechanisms can be adjusted. Each independent abutment mechanism is relatively independent and can be independently adjusted in position and abutment depth according to the specific shape characteristics of the irregularly shaped mold steel, ensuring that the lower end of the abutment bolt tightly fits the workpiece surface. Through the coordinated action of the V-shaped limiting groove and the independent abutment mechanisms, a contour-following, wrapping clamping of the irregularly shaped mold steel's cross-sectional contour is achieved, significantly improving the clamping fit and locking firmness, effectively avoiding the workpiece loosening and displacement problems caused by point or line contact in traditional planar clamping methods.

[0015] 2. This invention provides an adjustable cutting device for irregularly shaped mold steel. The device includes a bottom moving mechanism below the locking mechanism. After the locking mechanism fixes the position of the irregularly shaped mold steel, the bottom moving mechanism drives the entire locking mechanism and the workpiece to move horizontally. During this movement, the irregularly shaped mold steel remains stably clamped, completely avoiding the problems of rolling, tilting, and springback deviations caused by the relative sliding of the workpiece and the table surface in traditional feeding methods. Simultaneously, an auxiliary clamping mechanism is activated after the irregularly shaped mold steel moves to the designated cutting position but before the cutting operation begins. It provides auxiliary clamping from above to the area near the cutting point, forming a fixed constraint at both ends with the locking mechanism, further ensuring the stability of the cutting process and the quality of the cut surface.

[0016] 3. This invention provides an adjustable cutting device for irregularly shaped mold steel. In this device, the cutting mechanism is driven by an angle adjustment motor to rotate the drive gear, which in turn drives the driven gear to rotate, thereby achieving precise adjustment of the cutting disc angle to meet the requirements of different angles for beveling the end face of irregularly shaped mold steel. Simultaneously, this device also features an auxiliary locking structure consisting of a limit post, a moving push rod, and a moving frame: when the cutting disc is adjusted to the target angle, the moving push rod drives the moving frame forward, and the limit post is locked by the cooperation of auxiliary positioning groove two and auxiliary positioning groove one, thus reliably locking the driven gear. This effectively avoids the drift of the cutting disc angle caused by vibration or cutting force during the cutting process, ensuring the stability of the beveling angle and the cutting accuracy.

[0023] Working principle: In use, the irregularly shaped mold steel to be cut is inserted from the left end of the upper protective frame 2, and placed inside the limiting groove 1 502 and limiting groove 2 605. The top auxiliary frame 506 is placed above the irregularly shaped mold steel, and the mating insertion plate 505 and mating insertion groove 503 are used to connect the bottom support frame 501 and the top auxiliary frame 506. An appropriate number of independent abutment mechanisms are selected according to the external shape of the irregularly shaped mold steel to be cut. When placing the abutment mechanisms, the two positioning plates 512 are set longitudinally and inserted into the moving track 507. Then, the two positioning plates 512 are adjusted to be set laterally. The appropriate number of independent abutment mechanisms is selected according to the external shape of the irregularly shaped mold steel to be cut. After the appropriate abutment position is determined, the internal threaded tube 509 is moved upward by the auxiliary ring 510, and the positioning plate 512 moves into the corresponding positioning groove 508. The positioning plate 512 is assisted in positioning by the spring plate 513 cooperating with the auxiliary hole 514. Then, the abutment bolt 511 is rotated. With the cooperation of the abutment bolt 511 and the internal threaded tube 509, the lower end of the abutment bolt 511 moves towards the direction of the special-shaped mold steel to be cut and abuts and locks against the outer wall of the special-shaped mold steel to be cut. At the same time, the rotatable connection between the internal threaded tube 509 and the positioning plate 512 can automatically adjust the angle according to the shape of the special-shaped mold steel during the abutment process between the abutment bolt 511 and the outer wall of the special-shaped mold steel to be cut. The dimensions to be cut for the irregular mold steel are set via the control panel 4. During the cutting operation, the moving motor 901 drives the moving screw 902 to rotate. Through the cooperation of the moving screw 902 and the connecting plate 904, the connecting frame 905, the bottom support frame 501, the top auxiliary frame 506, and the irregular mold steel to be cut are moved to the right. The operation pauses when the target position is reached. The auxiliary electric push rod 602 drives the auxiliary clamping frame 603 to move downward. The limiting groove 605 and the clamping block 604 cooperate to provide auxiliary clamping for the irregular mold steel to be cut. During cutting, the angle adjustment motor 705 drives the drive gear 706 to rotate. The drive gear 706 and the driven gear 704 work together to rotate the cutting disc 709, thereby adjusting the cutting angle. During angle adjustment, the limiting post 710 above the driven gear 704 moves within the limiting track 714. After the angle is determined, the moving push rod 716 drives the moving frame 717 forward. The auxiliary positioning grooves 718 and 715 work together to lock the limiting post 710, thus controlling the driven gear. The reliable locking of the wheel 704 effectively prevents the angle drift of the cutting disc 709 caused by vibration or cutting force during the cutting process, ensuring the stability of the bevel cutting angle and the cutting accuracy. During the rotation adjustment of the driven gear 704 and the cutting disc 709, the rotating plate 712 achieves synchronous rotation through the synchronous frame 711, ensuring that the cutting through hole 713 is always directly below the cutting disc 709. Then, the top electric push rod 701 pushes the moving plate 703 and the cutting disc 709 downward, thereby enabling the cutting operation of the irregular mold steel to be cut. During the cutting process, the coolant in the storage tank 10 is introduced into the contact position between the cutting disc 709 and the shaped mold steel to be cut by the submersible pump 12. The sprayed coolant cools the cutting position of the cutting disc 709. After the cooling is completed, the liquid falls and enters the storage tank 10 through the drain hole 14. After being filtered by the impurity filter screen 13, it is recycled in the storage tank 10. After the cutting process is completed, the cut finished product is located above the auxiliary support block 601 on the right. During the movement of the irregular mold steel to be cut, the finished product is pushed out from the right side of the upper protective frame 2. When the irregular mold steel to be cut reaches the designated position, the cutting operation can be repeated.

[0024] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
