Abstract

The utility model relates to a socket joint formula concrete drain pipe, it includes the overhang roll tuber, overlaps the socket joint formula concrete drain pipe die 6 on the overhang roll tuber main shaft 5, its characterized in that (1) the inboard overhang roll tuber of socket joint formula concrete drain pipe die bellmouth is equipped with the runner 7 that accords with 8 bellmouth shapes of concrete drain pipe and can make relative pivoted with the main shaft on the cover. (2) The female end of the socket joint type concrete drain pipe die is connected with a circular plate-shaped female die head 9, and the upper side part of the inner edge of the circular plate-shaped female die head is contacted with the upper side part of the outer edge of the rotating wheel. The device is not only beneficial to improving the production quality of products, but also beneficial to reducing the production cost.

Description

Spigot-and-socket concrete drainpipe process units

The utility model relates to a kind of spigot-and-socket concrete drainpipe process units.

The overhang roll tuber is a common equipment of producing the concrete drainpipe.People use the pipe die (its structure is seen Fig. 1) that has the bellmouth internal mold to produce spigot-and-socket concrete drainpipe usually on the overhang roll tuber at present.The problem that exists is: (1) wants to feed than the big concrete of pipe shaft concrete water content to the socket of pipe die earlier, has therefore increased the workload of getting the raw materials ready.(2) since the briquetting pressure of concrete drainpipe faucet part less (can only be the extruding force extrusion modling of transmitting by the inboard pipe shaft concrete of bellmouth) so density is relatively poor, thereby influenced the quality of concrete drainpipe.(3) behind the concrete drainpipe roll-forming, the bellmouth internal mold needs to unload (because of concrete is not dried, will damage the drainpipe female end if pull down the bellmouth internal mold immediately) simultaneously with pipe die and drainpipe, waits to dry, and therefore, each pipe die must be prepared a bellmouth internal mold.

The purpose of this utility model is that a kind of spigot-and-socket concrete drainpipe process units will be provided, and it not only helps improving the quality of production of product, and helps reducing production costs.

Below in conjunction with drawings and Examples the utility model is specifically described.

Fig. 1 is existing spigot-and-socket concrete drainpipe process units section construction working state schematic representation.(1 is overhang roll tuber main shaft among the figure, and 2 is the concrete drainpipe, and 3 is pipe die, and 4 is the bellmouth internal mold).

Fig. 2 is the utility model section construction working state schematic representation.

With reference to accompanying drawing, the utility model comprises the overhang roll tuber, be placed in the spigot-and-socket concrete drainpipe pipe die 6 on the overhang roll tuber main shaft 5, it is characterized in that: be arranged with on the overhang roll tuber main shaft of (1) spigot-and-socket concrete drainpipe pipe die bellmouth inboard conform to concrete drainpipe 8 bellmouth shapes and can make runner 7 in relative rotation with main shaft.(2) female end of spigot-and-socket concrete drainpipe pipe die is connected with a ring flat-plate shape bellmouth die head 9, and the upper lateral part of ring flat-plate shape bellmouth die head inner edge contacts with the upper lateral part of runner outer rim.

Above-mentioned ring flat-plate shape bellmouth die head is made of annular slab and the interior cover connection that is connected in the annular slab inner edge, and annular slab is through linking towards the side plane of pipe die and the female end of spigot-and-socket concrete drainpipe pipe die.

The utility model is owing to can realize the direct roll-forming of concrete drainpipe socket cement by the cooperation of ring flat-plate shape bellmouth die head and runner, and therefore the concrete water pipe that processes is more closely knit, and product quality guarantees to some extent.In addition, because the female end of ring flat-plate shape bellmouth die head and concrete drainpipe is a plane contact, so after the machine-shaping of concrete drainpipe, ring flat-plate shape bellmouth die head can be pulled down, like this for the concrete drainpipe of producing with a kind of specification, need only dispose a ring flat-plate shape bellmouth die head, can with the pipe die cooperating of a plurality of specifications of the same race, thereby saved the cost of production equipment.

Claims

1. a spigot-and-socket concrete drainpipe process units comprises the overhang roll tuber, is placed in the spigot-and-socket concrete drainpipe pipe die 6 on the overhang roll tuber main shaft 5, it is characterized in that:

(1) be arranged with on the overhang roll tuber main shaft of spigot-and-socket concrete drainpipe pipe die bellmouth inboard conform to concrete drainpipe 8 bellmouth shapes and can make runner 7 in relative rotation with main shaft;

(2) female end of spigot-and-socket concrete drainpipe pipe die is connected with a ring flat-plate shape bellmouth die head 9, and the upper lateral part of ring flat-plate shape bellmouth die head inner edge contacts with the upper lateral part of runner outer rim.

2. spigot-and-socket concrete drainpipe process units according to claim 1, it is characterized in that, ring flat-plate shape bellmouth die head is made of annular slab and the interior cover connection that is connected in the annular slab inner edge, and annular slab is through linking towards the side plane of pipe die and the female end of spigot-and-socket concrete drainpipe pipe die.
