Description

TECHNICAL FIELD

[0001] The utility model relates to radial forging equipment technical field, concretely is a horizontal radial forging machine. BACKGROUND

[0002] Radial forging is the rotary forging method of processing solid or hollow long shaft parts, and two to eight hammer heads distributed in the circumferential direction of the bar hit the workpiece quickly and synchronously during forging. This forging forming technology is one of the important technologies in metallurgical production, and is widely used in the fields of aviation, aerospace, machinery, shipbuilding and other fields, and occupies an extremely important position in the national economy.

[0003] The existing horizontal radial forging machine needs to replace hammer heads of different sizes when processing workpieces of different diameters, so as to ensure high forging precision. However, the hammer heads are mainly fastened by two large bolts during replacement, and even multiple small bolts are additionally distributed on some radial forging machines. During the disassembly process, multiple bolts need to be operated for several turns, which consumes time and effort. UTILITARIAN CONTENT

[0004] Therefore, the utility model aims to provide a horizontal radial forging machine to solve the technical problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a horizontal radial forging machine, comprising a shell, a hammer seat and a hammer head, the both sides and the outer surface of the hammer seat are connected with a baffle, the both sides of the baffle are penetrated by a bolt, the outside of the bolt is fixed with a threaded sleeve, the top of the hammer head is connected with a limiting block and a supporting block respectively, and the both sides and the top of the limiting block and the supporting block are connected with a buffer pad.

[0006] By adopting the above technical scheme, first of all, when installing the hammer head, the worker inserts the limiting block and the supporting block into the hammer seat, so that the hammer head is attached to the hammer seat. Then the worker puts the baffle on the outer surface of the hammer seat, so as to block the surface of the limiting block, the supporting block and the hammer seat, improve the appearance, and then the worker inserts the bolt transversely through the baffle and the hammer seat, and connects the threaded sleeve with the limiting block by rotating the bolt, so as to limit the limiting block, thereby completing the installation operation. The limiting block cooperates with the supporting block to prevent the hammer head from moving up, down, left, right and backward, and the limiting block is prevented from falling forward by the baffle cooperating with the bolt and the threaded sleeve. The buffer pad reduces the impact force of the hammer head transmitted to the hammer seat, prolongs the service life of the structure, and the rough surface of the buffer pad has a certain friction force, which increases the resistance of the limiting block and the supporting block to slide out. When the hammer head needs to be replaced with another size after forging, the worker only needs to reverse the bolt to separate the threaded sleeve from the limiting block, then pull out the bolt and take off the baffle, and then the hammer head can be directly taken off from the hammer seat.

[0007] Further, the bottom of the shell is connected with a base, hydraulic cylinders are installed on the upper sides and lower sides of the shell, and the hammer base is connected to the output end of the hydraulic cylinder.

[0008] By adopting the above technical scheme, the staff passes the columnar workpiece through the shell through the feeding mechanism, and simultaneously opens the hydraulic cylinder. After the hydraulic cylinder is started, the output end drives the hammer base to reciprocate, so that the hammer head reciprocates. After the columnar workpiece passes through the shell, the workpiece is forged by being struck by the four hammer heads, so that the workpiece is forged into a specified shape. Meanwhile, the setting of the buffer pad reduces the impact force of the hammer head transmitted to the hammer base, prolongs the service life of the structure, and the rough surface of the buffer pad has a certain friction, which increases the resistance of the limiting block and the support block to slide out.

[0009] Further, the hammer base, the hammer head, the baffle, the bolt, the threaded sleeve and the limiting block are all provided with four, and the four hammer bases, the hammer heads, the baffles, the bolts, the threaded sleeves and the limiting blocks are all distributed in a ring array.

[0010] By adopting the above technical scheme, since the hammer base and the hammer head are provided with four, it is convenient to hammer forge in four directions of the workpiece at the same time. The baffle, the bolt, the threaded sleeve and the limiting block are all provided with four, which facilitates disassembly and assembly of the four hammer heads.

[0011] Further, the bolt is detachably connected with the hammer base and the baffle, and the baffle is detachably connected with the hammer base.

[0012] By adopting the above technical scheme, the staff inserts the limiting block and the support block into the hammer base, so that the hammer head is attached to the hammer base. Then the staff sleeves the baffle on the outer surface of the hammer base, so as to shield the surface of the limiting block, the support block and the hammer base, thereby improving the appearance. Then the staff inserts the bolt transversely through the baffle and the hammer base, and connects the threaded sleeve with the limiting block by rotating the bolt, so as to limit the limiting block.

[0013] Further, the threaded sleeve is threadedly connected with the limiting block, and the limiting block is in the shape of a spoon.

[0014] By adopting the above technical scheme, the staff inserts the bolt transversely through the baffle and the hammer base, and connects the threaded sleeve with the limiting block by rotating the bolt, so as to limit the limiting block. The limiting block is thick at the top and thin at the bottom, so as to avoid the hammer head from being displaced and falling downward.

[0015] Further, the support block is provided with two groups, and the two groups of support blocks are symmetrically distributed.

[0016] By adopting the above technical scheme, the limiting block cooperates with the support block to avoid the hammer head from being displaced and falling upward, downward, leftward, rightward and backward, thereby increasing the stability of the structure.

[0017] Further, the hammer head, the limiting block and the supporting block are detachably connected with the hammer seat, and the baffle abuts against the limiting block and the supporting block.

[0018] By adopting the above technical scheme, the worker inserts the limiting block and the supporting block into the hammer seat, and then the worker sleeves the baffle on the outer surface of the hammer seat, and the limiting block is abutted by the baffle cooperating with the bolt and the threaded sleeve, so that the hammer head is prevented from falling forward.

[0019] Further, the surface of the buffer pad is rough.

[0020] By adopting the above technical scheme, the buffer pad is arranged to reduce the impact force of the hammer head transmitted to the hammer seat, thereby prolonging the service life of the structure, and the rough surface of the buffer pad has a certain friction force, thereby increasing the resistance of the limiting block and the supporting block to slide out.

[0021] Further, the hammer seat, the baffle and the buffer pad are provided with through holes on both sides, and the diameters of the through holes are greater than the diameter of the threaded sleeve.

[0022] By adopting the above technical scheme, since the diameters of the through holes of the hammer seat, the baffle and the buffer pad are greater than the diameter of the threaded sleeve, the bolt and the threaded sleeve can directly penetrate the side surfaces of the hammer seat, the baffle and the buffer pad, and the threaded sleeve does not need to be rotated, but only needs to be rotated after the threaded sleeve contacts the limiting block, and then the bolt is rotated to rotate and tighten the threaded sleeve.

[0023] Further, one end of the bolt is provided with a hand wheel, and the shape of the hand wheel is hexagonal.

[0024] By adopting the above technical scheme, the hand wheel is arranged to facilitate the worker to rotate the bolt by hand to rotate the threaded sleeve, and since the hand wheel is hexagonal, the worker can rotate the bolt by using a wrench.
