Abstract
The utility model discloses a ratchet wheel feeding mechanism of a cold heading forming machine, comprising a driving swing arm, a ratchet wheel, a ratchet shaft and a detent, wherein, the ratchet wheel is connected with a feeding wheel through the ratchet shaft; the driving swing arm is movably sleeved on the ratchet shaft and connected with a transmission part. The structure of the ratchet wheel feeding mechanism is characterized in that a brake drum is arranged on the ratchet shaft at the side of the ratchet wheel; a lifting rocker is connected with the brake drum; an ejector pin is arranged on the lifting rocker and used for lifting the detent when the detent is back, the height that the detent is lifted by the ejector pin is more than the height of the ratchet tooth; a push pin is arranged on the driving swing arm and the lifting rocker is pushed to swing by the push pin. The detent and the ratchet wheel of the utility model have long service life and produce no noise at work.
Description
[technical field]
The utility model relates to a kind of cold-heading molding machine, and what be specifically related to is a kind of ratchet feed mechanism of cold-heading molding machine.
[background technology]
The cold-heading molding machine is a kind of the various metal wire rods of handling well to be carried out cold extrusion, makes the equipment of wire rod cold-heading molding in mould, is used to process various standards, non-standard securing member and the vapour accessory that rubs.The feeding of cold-heading molding machine adopts ratchet mechanism drive drawing-inroller to carry out feeding, because the ratchet of ratchet mechanism is when backhaul, ratchet can be close to the sliding friction of hook tooth back, not only can produce noise, and all can cause damage to ratchet and pawl, influence its service life.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of ratchet, ratchet long service life, does not produce the cold-heading molding machine ratchet feed mechanism of noise during work.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
The ratchet feed mechanism of cold-heading molding machine, comprise and drive swing arm, ratchet, ratchet shaft and ratchet, ratchet is connected with drawing-inroller by ratchet shaft, the driving swing arm is actively socketed on the ratchet shaft and is connected with drive disk assembly, it is characterized in that: the ratchet shaft of described ratchet side is provided with brake rim, be connected with on the brake rim and lift rocking arm, lift rocking arm and be provided with the ejector pin that when the ratchet backhaul, lifts ratchet, the height that ejector pin lifts ratchet is a bit larger tham the height of hook tooth, described driving swing arm is provided with distribution, promotes to promote to lift the rocking arm swing.The described rocking arm that lifts is provided with the distribution hole, promote hole and the corresponding setting of described distribution, distribution promotes to lift rocking arm by promoting the hole, and the diameter of promoting the hole is greater than the diameter of promoting, and its diameter difference is promoted after ejector pin lifts ratchet during with the ratchet backhaul and promoted to lift rocking arm at once and be advisable.
The beneficial effects of the utility model are: during owing to the ratchet backhaul, ratchet is picked up and is not contacted with the ratchet back of tooth, has avoided the friction of ratchet and ratchet, so, not only can not produce noise between the pawl-and-gearing, and not have wearing and tearing, prolonged the service life of ratchet, ratchet.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Structural representation when Fig. 2 is lifted by ejector pin for the utility model ratchet
Fig. 3 is the view after removing brake rim among Fig. 1 and lifting rocking arm
[specific embodiment]
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and operation principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1,3, the ratchet feed mechanism of this kind cold-heading molding machine, comprise and drive swing arm 1, ratchet 2, ratchet shaft 3, ratchet 16 and lift rocking arm 7, ratchet 2 is by ratchet shaft 3 and drawing-inroller (not drawing in the way) the coaxial connection, driving swing arm 1 is actively socketed on the ratchet shaft 3 and is connected with drive disk assembly, described ratchet 16 is fixed on the pawl axis 10 by pawl base 13, pawl axis 10 rotatable being located at drive in the swing arm 1, the axle head of pawl axis 10 also fixed cover is provided with crank 11, being installed in the adjustable displacements of cylinders 12 and the spring reference column 14 that drive in the swing arm 1 leans the crank 11 and ratchet 16 back sides respectively, ratchet 16 elasticity are abutted on the gear teeth of ratchet 2, the ratchet shaft in the described ratchet outside is provided with brake rim 4, establish brake block 5 in the brake rim, and regulate frictional force between brake rim 4 and the ratchet shaft 3 by spring regulating device 6, the described rocking arm 7 that lifts is fixedlyed connected with the outer ring of brake rim 4, lifting rocking arm 7 is provided with the ejector pin 15 that lifts ratchet when the ratchet backhaul (ejector pin rotates pawl axis 10 by roof pressure crank 11, thereby driving pawl base 13 rotates, ratchet is lifted leaves the ratchet gear teeth), the height that ejector pin lifts ratchet is a bit larger tham the height of hook tooth, highly be 1.5-2mm, described driving swing arm 1 is provided with promotes 9, the described rocking arm 7 that lifts is provided with distribution hole 8, promote hole 8 and described distribution 9 corresponding settings, distribution 9 promotes to lift rocking arm 7 by promoting hole 8, the diameter of promoting the hole is greater than the diameter of promoting, and its diameter difference is promoted 9 during with the ratchet backhaul and promoted to lift rocking arm 7 at once and be advisable after ejector pin 15 lifts ratchet.
The utility model is work like this: during feeding, drive disk assembly drives driving swing arm 1 and swings clockwise, so promoting ratchet 2, ratchet 16 clockwise rotates, ratchet 2 drives drawing-inroller rolling carrying out feeding, promote 9 simultaneously and promote to lift rocking arm 7 swing clockwise synchronously, promote this moment and abut against the right side of promoting the hole by promoting hole 8; When the ratchet backhaul, drive disk assembly drives and drives the swing arm counter-clockwise swing, owing to promote between hole and the distribution and have bigger gap, promote 9 and can not promote to lift rocking arm 7 at once, so produce relative motion between ejector pin 15 and the crank 11, ejector pin 15 roof pressure cranks 11 when crank rotates, thereby make ratchet 16 just be lifted (as shown in Figure 2) at the beginning by ejector pin 15 in backhaul, breaking away from ratchet 2 back of tooth does not contact with the ratchet back of tooth, when ratchet is picked up highly above behind the height of hook tooth, distribution 9 begins to contact with distribution 8 left sides, hole, promotes to lift rocking arm 7 with the synchronous counter-clockwise swing of driving swing arm, after backhaul puts in place so promote 9, drive disk assembly drives and drives swing arm swing clockwise once more, before promote promoting to lift rocking arm, ratchet return is close to the ratchet gear teeth and can be promoted ratchet again and carry out feeding, circulation according to this.
