Embodiment Construction
[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.
[0029] The production technology of a kind of push rod of the present invention, its processing step is as follows:
[0030] 1) Sawing and punching: cutting the aluminum alloy tube into blank 1, such as figure 1 As shown, the length of the blank 1 is 1457.5±0.5mm, and two positioning holes 11 with symmetrical positions and Φ4.2mm are opened on the blank, and the distance between the two positioning holes 11 is 116±0.3mm;
[0031] 2) Double bending: Use a double-head pipe bender to bend the billet at both ends, so that the billet can be bent into a shape such as figure 2 The first semi-finished product 2 shown, the first semi-finished product 2 includes: a first horizontal part 21, the first horizontal part 21 is 328 ± 0.3mm long, and the left and right ends of the first horizontal part 21 are respectively bent with...

Abstract
The invention discloses a production process of a hand push rod. The production process comprises the following machining steps that (1) sawing and punching are conducted, specifically, an aluminum alloy pipe is sawed into a blank; (2) double bending is conducted, specifically, the blank is subjected to double-head bending through a double-head pipe bending machine, so that the blank is bent intoa first semi-finished product; (3) horizontal bending is conducted, specifically, the first semi-finished product is subjected to horizontal bending through a first pressing die, so that the first semi-finished product is bent into a second semi-finished product; (4) vertical bending is conducted, specifically, two first bending parts in the second semi-finished product are subjected to vertical bending through a second pressing die, so that the second semi-finished product is bent into a third semi-finished product; (5) notching is conducted, specifically, notching is conducted on the two first bending parts in the third semi-finished product, and a fourth semi-finished product is formed; (6) groove milling is conducted, specifically, single-face grooves in the two first bending parts ofthe fourth semi-finished product are subjected to groove milling, and finally a finished product is formed; and (7) quality inspection is conducted on the finished product through a checking fixture.The hand push rod produced by the production process is beautiful in appearance and stable in structure, and the service life of the hand push rod is prolonged.
Description
technical field [0001] The invention relates to a production process of a hand push rod. Background technique [0002] A push rod will be arranged on small tool carts such as strollers and baby carriages. Traditional hand push rods are generally welded by multiple rods, but the welded push rods are not only ugly in appearance, but also the connection structure of the joints between the rods is unstable, and it is easy to Loosening or even breaking occurs. Contents of the invention [0003] The purpose of the present invention is to provide a production process capable of producing a hand push rod with a beautiful appearance and a long service life. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a production process of a hand push rod, the processing steps are as follows: [0005] 1) Sawing and punching: sawing the aluminum alloy tube into a blank with a length of 1457.5±0.5mm, and opening two positioning holes ...
