Abstract

The utility model provides a parison pipe grinding machine for cleaning the coarseness of the surface of roughcast pipe. The utility model is mainly characterized in that a wheel axle of the grinding wheel is axially and vertically arranged with the parison pipe; furthermore, the grinding wheel axle is connected with a reciprocating swing mechanism; therefore, the grinding form of the grinding wheel is axial reciprocating grinding, with the grinding veins in axial fine veins. The fine axial grinding veins can be removed in the cold pulling and cold rolling working procedure of the pipe. Therefore, the utility model can improve the surface quality of the rolled parison pipe.

Description

Base pipe milling drum

Technical field

It is rolling that the utility model relates to metal pipe material, is a kind of base pipe milling drum of putting shell sub-surface roughness in order.

Background technology

Generally speaking, the blank pipe that just rolls out, its surface is all more crude, and one deck oxide skin is particularly arranged, and therefore, this base Guan Zaileng dials and should handle through grinding before rolling.The abrasive grinding wheel mechanism that existing base pipe milling drum generally all includes base pipe feeder, support roller and is positioned at the support roller top, wherein, the wheel shaft of abrasive grinding wheel and base tubular axis are to be arrangeding the gear drive that also is provided with a clamping tube and makes it to rotate in the base pipe feeder in parallel.Such base pipe milling drum, in base pipe grinding process, the base pipe rotates under the drive of gear drive on the one hand, constantly pushes ahead simultaneously.As seen, so the grinding form will produce helical form grinding line at the base tube-surface, and this helical form grinding line is difficult to remove together, will influence the surface quality of cold group of cold rolled tube in cold group of cold rolling process under pipe.

Summary of the invention

The purpose of this utility model provides a kind of improved base pipe milling drum, makes it to be implemented in the following of base pipe and can remove the grinding lines that produces by in this road grinding process easily in cold group of cold rolling process together, with the quality of cold group of cold rolled tube of further raising.

Main design of the present utility model is change the set-up mode of abrasive grinding wheel, and make it to take place simultaneously a continuous reciprocating motion, thereby the version of change grinding line to eliminate this grinding line with convenience in the base pipe operation of rolling.Concrete scheme of the present utility model is, the same with existing base pipe milling drum, also include the abrasive grinding wheel mechanism that a base pipe feeder, a support roller and are positioned at the support roller top, characteristics of the present utility model are wheel shafts of making abrasive grinding wheel with the base tubular axis to vertical setting, and this emery wheel wheel shaft also links with a reciprocally swinging mechanism.

The utility model as mentioned above, because the set-up mode of abrasive grinding wheel and base tubular axis are to vertical, emery wheel will produce one as the reciprocal friction of wiping the rubber action simultaneously, then abrasive grinding wheel can be at base tube-surface grinding shaft to the grinding line, and this fine axial grinding line is to remove in the cold preface of exchanging work of pipe.Therefore, the utility model will improve the surface quality of rolled blank pipe.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Embodiment of the present utility model as shown in drawings.See by Fig. 1, the utility model stand is on ground guide 4, include the abrasive grinding wheel 7 that base pipe feeder (being designed to a dolly in the present embodiment) 3, one support roller 6 and is positioned at support roller 6 tops, the wheel shaft 8 of abrasive grinding wheel 7 and the 1 axial vertical setting of base pipe, and this an emery wheel wheel shaft 8 and a reciprocally swinging mechanism 5 are linked.See by figure again, the gear drive 2 that base pipe feeder in the utility model also includes a clamping tube and makes it to rotate, then in base pipe grinding process, base pipe 1 rotates under the drive of gear drive 2 on the one hand, constantly push ahead simultaneously, by abrasive grinding wheel back and forth axially grinding continuously by feeder (dolly) 3.

Claims

1, a kind of base pipe milling drum, the abrasive grinding wheel mechanism that includes base pipe feeder, support roller and be positioned at support roller top is characterized in that: the wheel shaft of abrasive grinding wheel and base tubular axis are to vertical setting, and this emery wheel wheel shaft also links with a reciprocally swinging mechanism.
