Abstract
The utility model provides a stroke-adjustable drop roll for a perforating machine. The stroke-adjustable drop roll comprises a base plate and a support wheel for containing a perforated material, wherein two ends on the base plate are respectively provided with a stand column of which the inner part is in a hollow structure, an air cylinder is arranged in the middle of the base plate, an inner connecting cover is connected above the air cylinder, the inner connecting cover is externally sleeved with an outer connecting cover, a support plate for supporting a support wheel is connected above the outer connecting cover, a guide support avoiding track offset is arranged at each of two sides under the support plate, each guide support is inserted into each stand column of which the inner part is in the hollow structure, two sides of the support plate are respectively provided with a support, the supports are connected with the support wheel by a rotating bearing, the air cylinder is in threaded connection with the inner connecting cover, and the inner connecting cover is in threaded connection with the outer connecting cover. The stroke-adjustable drop roll is simple in structure, convenient to manufacture, and low in cost, so that the stroke of the drop roll can be adjusted, and the use ratio of the perforating machine can be improved.
Description
Technical field
The utility model belongs to the technical field of punch, a kind of specifically punch of adjustable stroke dance roller.
Background technology
Piercing process was widely used and was very economical in seamless steel tube production process today.Current steel pipe's production middle punch technology more rationally and perforation realized automation; The effect of perforation process is that solid pipe is passed hollow hollow billet; But there is more problem in pipe, and for example wall thickness is different, and length is different; And the quality of surfaces externally and internally is different, need when perforation, regulate the height of support roller so exactly.
Summary of the invention
In order to address the above problem, the utility model provides a kind of punch of scalable dance roller stroke, drives the rising or the decline of support roller through cylinder, thereby realizes the scalable lifting travel.
In order to achieve the above object, the utility model is realized through following technical scheme:
The utility model is a kind of punch adjustable stroke dance roller; Comprise base plate and place the support roller that is perforated material; The two ends column that an inside is set respectively is hollow structure is placed a cylinder in the centre position of base plate on base plate, above cylinder, connects adapter sleeve in; Adapter sleeve outside sheathed one outside interior adapter sleeve, outside the top of adapter sleeve connect one support support roller supporting plate.
The further improvement of the utility model is: below supporting plate two ends all be provided with one prevent offset track guiding trestle, each guiding trestle is inserted into respectively that each is inner in the column of hollow structure.
The further improvement of the utility model is: be provided with a carriage respectively in two ends of bearing plate, carriage connects support roller through rolling bearing.
The further improvement of the utility model is: cylinder and interior adapter sleeve are through being threaded, and interior adapter sleeve is through being threaded with outer adapter sleeve.
The beneficial effect of the utility model is: cylinder drives carriage and rises or descend; Guiding trestle inserts in the column; Prevent to depart from support roller and depart from predetermined rolling curve, inside and outside adapter sleeve can also be regulated height between the two through being threaded, the stroke of adjusting dance roller that just can be wider.
The utility model is simple in structure, and is easy to make, with low cost, can regulate the stroke of dance roller, improved the utilization rate of punch.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In order to deepen understanding to the utility model, will combine accompanying drawing and embodiment that the utility model is described in further detail below, this embodiment only is used to explain the utility model, the utility model protection domain is not constituted to limit.
Shown in Fig. 1, the utility model is a kind of punch adjustable stroke dance roller, comprises base plate 1 and support roller 6; Place perforated material on the said support roller 6, the two ends column 2 that an inside is set respectively is hollow structure on said base plate 1, placing one in the centre position of said base plate 1 can straight-line cylinder 3; Above said cylinder 3, connect adapter sleeve 4 in, said cylinder 3 and said interior adapter sleeve 4 are through being threaded, adapter sleeve 5 outside sheathed outside the adapter sleeve 4 in said; Adapter sleeve 4 and said outer adapter sleeve 5 are through being threaded, can increasing the motion height of dance roller in said, outside said adapter sleeve 5 above the supporting plate 7 of the said support roller 6 of connection one support; Below said supporting plate 7 two ends all be provided with one prevent offset track guiding trestle 9; Said each guiding trestle 9 is inserted into respectively in the column 2 that each said inside is hollow structure, and when moving up and down, guiding trestle 9 moves in said column 2; Prevent the support roller offset track; Make machining hole more accurate, on said supporting plate 7 two ends, be provided with a carriage 8 respectively, said carriage 8 connects said support roller 6 through rolling bearing.
The course of work of the utility model is: with processed steel pipe be placed on said support roller 6 above; The movement travel of processed steel pipe is regulated through following cylinder 3; Adapter sleeve 4 in cylinder 3 connects, interior adapter sleeve 4 outer sheathed outer adapter sleeves 5, outer adapter sleeve 5 is connected with carriage 8 with the supporting plate 7 that supports support roller 6; When cylinder moving, the movement travel of support roller 6 just can have been regulated like this.
The utility model is simple in structure, and is easy to make, easy to operate, can regulate the stroke of dance roller, improved the utilization rate of punch.
