Embodiment 1

[0019] Embodiment 1 is basically as attached figure 1 and figure 2 Shown: a processing device for special-shaped covers with inner lugs, including a base 1, on which an electric furnace 16, a punching machine 12, and a ring rolling machine 9 are arranged in sequence, and a support frame 2 is also provided on the base 1, and on the support frame 2 A cross bar 7 is provided, and a slide block 5 is slidably connected to the cross bar 7. A drive mechanism for driving the slide block 5 to slide on the cross bar 7 is provided on the support frame 2. The drive mechanism includes two coils arranged on the support frame 2 Wire wheel 3 and the stay cord 4 that is wound on the reel 3, the two ends of stay cord 4 are fixedly connected with the left and right sides of slide block 5 respectively, and support frame 2 is provided with the motor 8 that drives the reel 3 to rotate , the slider 5 is fixed with a connecting rod 6, the bottom end of the connecting rod 6 is fixed with a rotating ...

Embodiment 2

[0021] Embodiment 2, on the basis of Embodiment 1, the following content is added: the cross bar 7 is provided with a T-shaped chute, and the slider 5 slides in the chute. Through such arrangement, the slider 5 is accommodated in the chute, which increases the stability when sliding.

Embodiment 3

[0022] Embodiment 3 differs from Embodiment 2 in that: the sliding block 5 is provided with a rectangular through hole, and the sliding block 5 is slidably socketed on the cross bar 7 through the through hole. Through such arrangement, the cross bar 7 is accommodated in the slider 5, which increases the stability during sliding.

Abstract

The invention discloses a machining device for an inner lifting lug specially-shaped cover, and relates to the technical field of forging. The machining device comprises a base; an electric furnace, a punching machine and a ring rolling machine are sequentially arranged on the base, a supporting frame is further arranged on the base, a transverse rod is arranged on the supporting frame, a sliding block is glidingly connected to the transverse rod, a driving mechanism for driving the sliding block to slide on the transverse rod is arranged on the supporting frame, a connecting rod is fixed to the sliding block, a rotating shaft is fixed to the bottom end of the connecting rod, an electric telescopic rod is rotationally connected to the rotating shaft, a pneumatic mechanical claw is arranged at the end, away from the connecting rod, of the electric telescopic rod, a groove is formed in the connecting rod, a driving block is glidingly connected into the groove, an air cylinder is arranged in the groove, a driving shaft is arranged on the driving block, a driving rod is rotationally connected to the driving shaft, and the driving rod is rotationally connected with the electric telescopic rod. According to the device, the driving mechanism, the electric telescopic rod and the air cylinder are controlled to operate, the mechanical claw is driven to move in all positions, the problem that labor is wasted when blanks are manually clamped and transferred is solved, and the dangerous condition caused by unstable manual clamping is also avoided.

Description

technical field [0001] The invention belongs to the technical field of forging, and in particular relates to a processing device for special-shaped covers of inner lifting lugs. Background technique [0002] The special-shaped cover part is used in the space launch cabin and is an important protective cover for rocket electronic instruments. Its maximum outer diameter is Φ612, the minimum inner diameter is Φ450, the height is 430, and the minimum wall thickness is 3mm. The existing special-shaped cover is processed by ZL205A aluminum alloy castings. The special-shaped cover processed by ZL205A aluminum alloy castings is restricted by many factors such as mold structure, air permeability of molding sand, dryness and humidity, pouring temperature, pouring speed, moisture retention time, etc. There are always defects such as pores, sand holes, and looseness at the roots of the two lifting lugs that cannot be eradicated. The root defect is treated by grinding, surfacing, and st...
