Abstract

The invention discloses an ejection rod installation and removal device, which comprises a bench frame (1) and a feeding hook (3). One ends of a plurality of material collection arms (5) are arranged at corresponding positions of the feeding hook (3), and the other ends of the material collection arms (5) are connected with a speed reducer (17). The ejection rod installation and removal device is characterized in that each material collection arm (5) is movably provided with a swinging arm (6), a touch head (8) is arranged on the material collection arms (5) in a sliding way and is provided with a disc spring (10), and a disc spring box (11) is fixedly connected with the material collection arms (5); the middle part of each material collection arm (5) is provided with a rocker arm (13), each rocker arm (13) rotates around a pin shaft on the corresponding material collection arm (5), and the middle part of each rocker arm (13) is provided with a cushion plate (14); a plurality of delivery rollers (18) are arranged under the ends of the material collection arms (5) corresponding to the feeding hook (3); and the material collection arms are provided with a disc spring buffering device. A swinging arm rotates around the pin shaft to compress the spring during collision of an ejection rod against the swinging arm, the collision of the ejection rod against the material collection arms can be buffered, the damage to the speed reducer and the wear of shaft sleeves of the material collection arms can be reduced, and noise can also be reduced. Each rocker arm can be adjusted separately, inclination of the ejection rod can be fundamentally eliminated during rolling, the ejection rod can fall into the space between the material collection arms and the bench frame, and faults in production can be reduced.

Description

A kind of push rod assembling and removing device

Technical field:

The present invention relates to technical field of metallurgical machinery, is a kind of push rod assembling and removing device specifically.

Background technology:

At present, the push rod assembling and removing device of pipe production line can not be adjustable separately owing to connect material arm; And buffer unit is not set, and 2 tons of weights of a push rod add impulsive force; The arm that connects material is stressed very big, often causes the damage of push rod assembling and removing device reductor and connects material arm axle cover serious wear; Equipment is after operation a period of time, because each arm height that connects material is inconsistent, push rod is tilted, and falls connecting material between arm and stand, causes the production fault.

Summary of the invention:

The objective of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of push rod assembling and removing device is provided, mainly solve the stressed big damage equipment of the arm that connects material of existing push rod assembling and removing device and cause problems such as production fault.

In order to achieve the above object, the present invention is achieved in that a kind of push rod assembling and removing device, and it comprises stand, on stand, establishes the feed hook, and oscillating motor is fixedly connected with the feed hook, and oscillating motor drives the swing of feed hook; At the correspondence position of the maximum displacement of feed hook swing is the end of arm of connecting material, and the other end of the arm that connects material is connected with reductor through connecting rod, and its special character is that an end activity corresponding with the feed hook on the arm that connects material establishes swing arm; Swing arm is rotated around bearing pin, on the arm that connects material, establishes and meets and discusses, and meets and discusses and on the arm that connects material, slides; Meet and discuss and contact with swing arm; The dish spring is housed on meeting and discussing, and the dish spring is contained in the dish spring case, and dish spring case is fixedly connected with the arm that connects material; Rocking arm is established at middle part at the arm that connects material, and rocking arm rotates around bearing pin on the arm that connects material, and establishes backing plate in the middle of the rocking arm; Below the arm end corresponding that connect material, establish conveying roller with the feed hook.

Compared with present technology a kind of push rod assembling and removing device of the present invention has outstanding substantive distinguishing features and marked improvement; 1, on the arm that connects material, add dish spring buffer unit, push rod bumps against in the swing arm, and swing arm is rotated around bearing pin; The compact disc spring; Slow down push rod and the bump of the arm that connects material, reduce the wearing and tearing that reductor damages and the arm axle that connects material overlaps, and reduced noise; 2, the rocking arm on each arm that connects material is adjustable separately, eliminates push rod basically and rolls tiltedly, falls connecting material between arm and stand, reduces the production fault.

Description of drawings:

Fig. 1 is a structural representation of the present invention.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and specify the present invention.

Embodiment 1, and referring to Fig. 1, at the stand 1 other feed hook 3 of installing, oscillating motor 4 is fixedly connected with feed hook 3, and oscillating motor 4 drives 3 swings of feed hook, and the push rod on the stand 12 is delivered on the arm 5 that connects material; At the correspondence position of the maximum displacement of feed hook 3 swing is the end of arm 5 of connecting material, and swing arm 6 is rotatably connected with the arm 5 that connects material through second bearing pin 9, and swing arm 6 is rotated around bearing pin, meet and discuss 8 and the arm 5 that connects material be slidingly connected through first bearing pin 7; Meet and discuss and 8 on the arm 5 that connects material, slide, meeting and discussing 8 contacts with swing arm 6, meets and discusses dish spring 10 to be housed on 8; Dish spring 10 is contained in the dish spring case 11, and dish spring case 11 is fixedly connected with arm 5 usefulness the 3rd bearing pin 12 that connects material, when push rod 2 is rolled into the 5 last times of arm that connect material; Collision swing arm 6 makes swing arm 6 around the rotation of second bearing pin 9, meets and discusses 8 to move down; Compact disc spring 10 reduces the connect material impact of arm 5 and reductor 17 of 2 pairs of push rods, reduces the push rod collision noise that arm 5 produces that connects material simultaneously; The other end of arm 5 of connecting material is connected with reductor 17 through connecting rod 16, at the middle part of each arm 5 that connects material rocking arm 13 is installed, and the arm 5 that connects material is fixedly connected by the 4th bearing pin 15 with rocking arm 13, and each rocking arm 13 centre adds backing plate 14, and is adjustable separately; Below the corresponding end of connect material arm 5 and feed hook 3, conveying roller 18 is installed, reductor 17 drivening rods 16, connecting rod 16 drives connect material arm 5 and rocking arm 13, and rocking arm 13 is put into push rod 2 on the conveying roller 18 around 15 rotations of the 4th bearing pin.
