[0003] The matching structure of the feeding trolley and the guide rail of the cold rolling mill feeding mechanism in the prior art is to directly match the two sides of the bottom of the feeding trolley in the length direction with the guide rail platforms on both sides of the trolley body. Although it has the advantages of convenient processing and installation, the feeding trolley will vibrate during the movement, and the gap between the guide rail tables on both sides of the trolley body and the feeding trolley is large, and the trolley is prone to vibration during movement. Shaking or swimming, causing the movement of the feeding trolley to be unsteady

Embodiment Construction
[0014] In order to enable the examiners of the patent office, especially the public, to understand the technical essence and beneficial effects of the present invention more clearly, the applicant will describe in detail the following in the form of examples, but none of the descriptions to the examples is an explanation of the solutions of the present invention. Any equivalent transformation made according to the concept of the present invention which is merely formal but not substantive shall be regarded as the scope of the technical solution of the present invention.
[0015] See figure 1 with figure 2 , the given feeding trolley body 1 is connected with the power transmission device of the cold rolling mill feeding mechanism through a pair of screw mandrels 14, and the forward and reverse rotation of a pair of screw mandrels makes the feeding trolley body 1 reciprocate. Depend on figure 1 As shown, a first sliding opening 11 is formed on one side of the length direction...

The invention relates to a matching mechanism of a feed-in trolley and a guide rail of a cold-rolling pipe mill feed-in mechanism, and belongs to the technical field of machining machines for metal pipes. The feed-in trolley comprises a feed-in trolley body. The matching mechanism of the feed-in trolley and the guide rail is characterized by comprising a trolley bed body, a bed frame, a first trolley guide rail plate and a second trolley guide rail plate, wherein the trolley bed body is fixed on the bed frame; a first guide rail platform is formed on the upper part of one side in the length direction of the trolley bed body, and a second guide rail platform is formed on the upper part of the other side in the length direction of the trolley bed body; the first guide rail plate corresponds to the second guide rail platform; the first trolley guide rail plate and the first guide rail platform are fixed, and the first guide rail platform extends from the side, which faces the second guide rail platform, of the first trolley guide rail plate and is sliding fit with one side of the feed-in trolley body; and the second trolley guide rail plate and the second guide rail platform are fixed, and the second guide rail platform extends from the side, which faces the first guide rail platform, of the second trolley guide rail plate and is sliding fit with the other side of the feed-in trolley body. The matching mechanism has the advantage of ensuring the motion stability of the feed-in trolley body.
Description
technical field [0001] The invention belongs to the technical field of metal pipe material processing machinery, and in particular relates to a matching structure of a feeding trolley and a guide rail of a feeding mechanism of a cold-rolled pipe mill. Background technique [0002] The complete set of cold-rolled pipe mill is mainly composed of roll mechanism, mandrel clamping and rotating mechanism and feeding mechanism. The feeding trolley is one of the important components of the feeding mechanism. Its duty is to push the steel pipe, so the industry also calls it the feeding trolley. for the propeller. According to common knowledge, especially based on the introduction of the patent documents that are not limited to those listed below, it can be known that the feeding trolley relies on the reciprocating motion of the guide rail. , CN201543661U and CN201592194U etc. all mention that there is a feeding mechanism. [0003] The matching structure of the feeding trolley and t...
