Description

Technical Field

[0001] The present invention relates to the technical field of ring forgings, and specifically relates to a clamping component for ring forgings. Background Technique

[0002] Ring forgings are products in the forging industry and a type of forgings. They are ring-shaped objects formed by applying external forces to metal billets (excluding plates) and shaping them through plastic deformation to meet the required compressive forces. When positioning forgings, fixture parts are used to position and limit the forgings. This clamping component is a fixture part for limiting and positioning ring forgings.

[0003] When positioning ring forgings, multiple clamping ends are used to press and limit multiple surfaces of the forgings, thereby limiting the forgings. However, the sizes of the forgings vary, and the sizes clamped and limited by the fixture parts are single, resulting in difficulty for the fixture parts to adapt to forgings of different sizes. In addition, when multiple fixture ends clamp the outer wall of the forging, the outer wall of the forging will be blocked by the fixture ends, which is not conducive to processing the ring forging, and the overall flexibility during use is poor. Summary of the Invention

[0004] The purpose of the present invention is to provide a clamping component for ring forgings to solve the problem proposed in the above background technique that when positioning ring forgings, multiple clamping ends are used to press and limit multiple surfaces of the forgings, thereby limiting the forgings. However, the sizes of the forgings vary, and the sizes clamped and limited by the fixture parts are single, resulting in difficulty for the fixture parts to adapt to forgings of different sizes. In addition, when multiple fixture ends clamp the outer wall of the forging, the outer wall of the forging will be blocked by the fixture ends, which is not conducive to processing the ring forging, and the overall flexibility during use is poor.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A clamping component for ring forgings includes a rectangular base. A rectangular chute is opened in the middle of the base. A slideway connected to the chute is opened at the upper end wall of the base near the chute. A threaded rod rotatably connected to the base is arranged in the chute. A pair of sliding seats that are threadedly connected to the threaded rod and move in opposite or opposite directions are movably connected in the chute. A cylindrical limiting roller for limiting the ring forging is arranged at the upper end of the sliding seat. When the threaded rod rotates, the limiting rollers move in opposite directions and contact and position the inner ring wall of the forging placed at the center of the upper end of the base. Fixed blocks are fixedly connected to both side end walls of the top of the base near the slideway. A screw rod for tightening and limiting the outer ring wall of the forging is horizontally penetrated and threadedly connected to the center end wall of the fixed block.

[0006] Preferably, a cylindrical fixing column is fixedly connected to the upper end wall of the sliding seat. A fixing block is fixedly connected to the top end wall of the fixing column. The upper end of the fixing block is disc-shaped, and the lower end of the fixing block is a frustum-shaped structure that is wider at the top and narrower at the bottom.

[0007] Preferably, a movable cavity is formed in the lower end wall of the limiting roller. A cylindrical movable channel for movably connecting the fixing column is formed in the inner side of the lower end of the limiting roller adjacent to the movable cavity. The shape and structure of the movable cavity match those of the fixing block, and the size of the movable cavity is larger than that of the fixing block.

[0008] Preferably, an interference fit structure is formed between the fixing block and the movable cavity. When the limiting roller is lifted, the fixing block moves downward in the movable cavity and forms an interference fit to form a clamping connection.

[0009] Preferably, rectangular through holes are vertically penetrated through the four corner end walls of the base. A rectangular support pad is fixedly connected to the end wall at one end angle of the through hole adjacent to the center of the base. A fixing ring is fixedly connected to the top end of the support pad. A positioning hole for passing through a bolt member to position and install the fixing ring is vertically penetrated through the end wall of the fixing ring.

[0010] Preferably, rectangular sliding strips are fixedly connected to the end walls at the corners of the base adjacent to the through holes. There are four sliding strips, and rectangular sliding blocks are installed on the side of the sliding strips.

[0011] Preferably, a sliding strip opening movably connected to the sliding strip is penetrated diagonally through the end wall of the sliding block. A rectangular buckle is fixedly connected to the center end wall of the upper end of the sliding block. A rectangular inner plate is installed on the side of the buckle.

[0012] Preferably, a rectangular clamping groove for clamping the buckle is formed in the bottom of the inner plate. A rectangular sponge plate is adhered to the side of the inner plate.

[0013] Preferably, connection grooves are formed in the middle of the front and rear sides of the upper end of the base. A connection seat is movably connected inside the connection groove. A rectangular seat core opening is formed in the center end wall of the connection seat. Support rollers are rotatably connected to the front and rear end walls of the connection seat adjacent to the seat core opening. A lead screw threadedly connected to the base is vertically penetrated and rotatably connected to the end wall of one side of the connection seat adjacent to the seat core opening.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, the annular forging is placed at the center of the upper end of the base, and the inner opening of the annular forging is placed inside the two limiting rollers. At this time, the threaded rod is rotated to drive the two sliding seats to slide and move away from each other inside, and the limiting rollers are linked to move through the slideway, so that the end walls of the two limiting rollers contact the inner ring wall of the annular forging to limit the forging, achieving the purpose of simply positioning the forging. Moreover, the screw can be tightened so that the end of the screw contacts the outer ring wall of the forging to strengthen the limiting property of the forging. At the same time, most of the upper end wall and side wall of the forging are exposed, facilitating subsequent processing of the forging.

[0016] 2. When the present invention is in use, when it is necessary to simply limit a forging and enable the forging to be simply rotated and adjusted, first rotate the screw rod. The screw rod is in transmission with the base, move the screw rod upward, and drive the connecting seat rotatably connected to the screw rod, so that the connecting seat slides upward in the connecting groove. At this time, the supporting roller also moves upward, and the lower end wall of the forging is supported by the supporting roller. At this time, rotate the forging. Through the rolling of the supporting roller, the rotation of the forging is assisted to perform self-rotation, which is more flexible and convenient to use and the regulation is convenient.

[0017] 3. The slide bar and the slide bar opening of the present invention are movable and are used to slide the sliding block, drive the top of the sliding block to be clamped through the buckle and the card slot, and the connected inner plate is located. The inner plate and the sponge plate are synchronously located at the outer wall of the forging supported near the upper end of the base. At this time, tighten the screw passing through and threadedly connected to the front end wall of the sliding block to limit the sliding block. When the forging rotates, the forging is wiped with the sponge plate made of sponge material to clean the dust and impurities on the end wall of the forging. At the same time, the clamping of the buckle and the card slot facilitates the disassembly and assembly of the inner plate. Then, rotate the inner plate by 90 degrees to change the orientation of the inner plate, and then clamp the sliding block and the inner plate to change the end face of the sponge plate wiping the end wall of the forging, which is convenient for the alternative use of each end face of the sponge plate, more convenient to use, and also convenient to remove the inner plate and the sponge plate for cleaning.

[0018] 4. When it is necessary to firmly position the forging in the present invention, rotate the screw rod to drive the connecting seat, so that the connecting seat slides downward in the connecting groove. At this time, the supporting roller also moves downward, and the forging contacts the upper end wall of the supporting pad. Cooperating with the upper end face of the base, the forging is supported. Among them, the supporting pad is made of metal, and the top end wall of the supporting pad is made of rubber, which increases the friction when contacting the forging and prevents the forging from rotating. Cooperating with the screw rod, the positioning firmness of the forging is strengthened.

[0019] 5. When the limiting roller is lifted in the present invention, the fixing column and the fixing block move downward in the movable channel and the movable cavity respectively. An interference fit is carried out between the fixing block and the movable cavity for clamping, so as to achieve the purpose of limiting the limiting roller. Furthermore, the forging positioned by the limiting roller is also limited accordingly and cannot rotate, which is more flexible and convenient when positioning the forging.

[0031] A movable cavity 9 is opened in the lower end wall of the limiting roller 6. A cylindrical movable channel 10 for movably connecting the fixing column 7 is opened near the inner side of the lower end of the limiting roller 6 close to the movable cavity 9. The shape and structure of the movable cavity 9 match the shape and structure of the fixing block 8. The size of the movable cavity 9 is larger than the size of the fixing block 8. The fixing block 8 and the movable cavity 9 form an interference fit structure. When the limiting roller 6 is lifted, the fixing block 8 moves downward into the movable cavity 9 and forms a clamping connection through interference fit. Rectangular through holes 13 are vertically penetrated through the four corner end walls of the base 1. A rectangular support pad 16 is fixedly connected to the end wall of the through hole 13 near one side end angle of the center of the base 1. A fixing ring 14 is fixedly connected to the top end of the support pad 16. A positioning hole 15 for passing through a bolt member to position and install the fixing ring 14 is vertically penetrated through the end wall of the fixing ring 14;

[0032] Rectangular sliding strips 17 are fixedly connected to the end walls of the through holes 13 near the end angles of the base 1. There are four sliding strips 17. A rectangular sliding block 18 is installed on the side of the sliding strip 17;

Support rollers 27 are rotatably connected to the front and rear end walls of the connecting seat 25 near the seat core opening 26. A lead screw 28 threadedly connected to the base 1 is vertically penetrated and rotatably connected to the end wall of the connecting seat 25 near one side of the seat core opening 26.

[0034] In summary, when the annular forging clamping component is in use,

[0035] Place the annular forging at the center of the upper end of the base 1, and position the inner opening of the annular forging inside the two limiting rollers 6. At this time, rotate the threaded rod 4 to drive the two sliding seats 5 to slide inward and move away from each other. Through the slideway 3, the limiting rollers 6 are linked to move, so that the end walls of the two limiting rollers 6 contact the inner ring wall of the annular forging to limit the forging, achieving the purpose of simply positioning the forging. Moreover, the screw 12 can be tightened so that the end of the screw 12 contacts the outer ring wall of the forging to strengthen the limiting property of the forging. At the same time, most of the upper end wall and side wall of the forging are exposed, facilitating subsequent processing of the forging;

[0036] When in use, when it is necessary to simply limit the forging and enable the forging to rotate and adjust simply, first rotate the lead screw 28. The lead screw 28 is in transmission with the base 1. Move the lead screw 28 upward and drive the connecting seat 25 rotatably connected to the lead screw 28, so that the connecting seat 25 slides upward in the connecting groove 24. At this time, the supporting roller 27 also moves upward. Use the supporting roller 27 to support the lower end wall of the forging. At this time, rotate the forging. Through the rolling of the supporting roller 27, the forging is assisted to rotate and perform self-rotation, making it more flexible and convenient to use and facilitating regulation;

[0037] Among them, the fixing block 8 and the fixing column 7 are respectively movably connected in the movable cavity 9 and the movable channel 10, facilitating the rotation of the limiting roller 6. Furthermore, the forging positioned by the limiting roller 6 can rotate therewith;

[0038] Moreover, the slide bar 17 and the slide bar opening 19 are movable, used to slide the sliding block 18. The top of the sliding block 18 is connected by buckling through the buckle 20 and the card slot 22. The inner plate 21 is located. The inner plate 21 and the sponge plate 23 are synchronously located at the outer wall of the forging supported near the upper end of the base 1. At this time, tighten the screw passing through and threadedly connected to the front end wall of the sliding block 18 to limit the sliding block 18. When the forging rotates, the forging is wiped with the sponge plate 23 made of sponge material to clean the dust and impurities on the end wall of the forging. At the same time, the buckling of the buckle 20 and the card slot 22 facilitates the disassembly and assembly of the inner plate 21. Then, rotate the inner plate 21 by 90 degrees to change the orientation of the inner plate 21, and then buckle the sliding block 18 and the inner plate 21 to change the end face of the sponge plate 23 wiping the end wall of the forging, facilitating the alternating use of each end face of the sponge plate 23. It is more convenient to use and also convenient to remove the inner plate 21 and the sponge plate 23 for cleaning;

[0039] When it is necessary to firmly position the forging, rotate the lead screw 28 to drive the connecting seat 25, so that the connecting seat 25 slides downward in the connecting groove 24. At this time, the supporting roller 27 also moves downward. The forging contacts the upper end wall of the supporting pad 16, and together with the upper end face of the base 1, supports the forging. Among them, the supporting pad 16 is made of metal, and the top end wall of the supporting pad 16 is made of rubber, increasing the friction when contacting the forging to prevent the forging from rotating. Together with the screw 12, the positioning firmness of the forging is strengthened;

[0040] Among them, the limiting roller 6 is lifted, and the fixing column 7 and the fixing block 8 move downward in the movable track 10 and the movable cavity 9 respectively. An interference fit is carried out between the fixing block 8 and the movable cavity 9 for clamping, so as to achieve the purpose of limiting the limiting roller 6. Furthermore, the forging positioned by the limiting roller 6 is also limited accordingly and cannot rotate self. When positioning the forging, it is more flexible and convenient;

[0041] The positioning hole 15 at the fixing ring 14 is provided with a bolt piece to position and install the fixing ring 14 on the supporting surface, such as the processing table, and then position and install the entire base 1.
