Problems solved by technology

An important consumable accessory in the bar feeder is the PU rubber hose used as the metal bar transmission channel. When the equipment is running, because it is always under high temperature conditions, the PU rubber hose is prone to heat aging, resulting in bending deformation and frequent replacement. PU rubber hose has become an expensive cost in the bar production process. How to prolong the service life of PU rubber hose or enhance its heat resistance is a problem to be solved.

Embodiment 1

[0027] Such as figure 2 Shown:

[0028] As one of the preferred solutions, the aluminum plate 3 is bonded to the lower end surface of the pipe body.

[0029] Preferably, the upper end surface of the aluminum plate 3 is a zigzag edge 4 , and the zigzag edge 4 is embedded in the pipe body 1 .

[0030] Preferably, the upper end of the aluminum plate 3 is extended with a curved hook portion 5 , and the hook portion 5 is further inserted into the interior of the pipe body 1 for fixing.

Embodiment 2

[0032] Such as image 3 Shown:

[0033] As one of the preferred solutions, the aluminum plate 3 is embedded in the pipe body 1, and the aluminum plate 3 and the pipe body 1 are fixedly connected by rivets.

[0034] Preferably, the aluminum plate 3 is two L-shaped reinforcing ribs 6, which are respectively arranged inside the bottom of the tube body 1 on both sides.

[0035] Preferably, the rivets are magnetic rivets. Magnetic rivets can firmly fix the PU rubber hose on the bar feeder, which can prevent abnormal vibration caused by the equipment running, and is conducive to improving the yield rate.

[0036] When making PU rubber hose, first place the aluminum plate at the bottom of the mold, then introduce polyurethane (PU material) colloid into the mold, and then solidify into a whole to get the finished product.

Abstract

The invention discloses a PU rubber tube. The PU rubber tube comprises a tube body prepared from a PU material, wherein an inward-concave arc-shaped groove is formed in the upper part of the tube body; the PU rubber tube is characterized in that the lower end of the tube body is connected with a hard material plate for preventing the tube body from bending deformation; the hard material plate is a metal plate; the metal plate is made of aluminum. The PU rubber tube is simple in structure, firm and durable; as the hard material with high deformation resistance and high heat resistance is additionally arranged on the PU rubber tube, the heat resistant performance of the PU rubber tube is improved, the PU rubber tube is prevented from bending deformation in the early period, the service life is prolonged, furthermore the change rate of the PU rubber tube is reduced, and the production cost is reduced.

Description

technical field [0001] The invention belongs to an accessory of a bar feeding machine, and in particular relates to a PU rubber hose used for transporting metal bars. Background technique [0002] Bar feeding machine, as the name suggests, refers to a feeding machine that cooperates with equipment that can continuously process bar materials to realize automatic feeding, thereby improving the processing efficiency and automation of the equipment. An important consumable accessory in the bar feeder is the PU rubber hose used as the metal bar transmission channel. When the equipment is running, because it is always under high temperature conditions, the PU rubber hose is prone to heat aging, resulting in bending deformation and frequent replacement. PU rubber hose has become an expensive cost in the bar production process. How to prolong the service life of PU rubber hose or enhance its heat resistance is a problem to be solved. Contents of the invention [0003] The purpose...
