Abstract
The utility model relates to duplex metal saw blade high-speed steel tooth material rolling forming equipment and provides an adjusting mechanism of a four-roll rolling forming machine. Rollers are installed in roller supporting seats. Adjusting screw seats are rotatably installed on the roller supporting seats. Four rollers are provided with two fine adjusting mechanisms in the horizontal direction and in the vertical direction. A fine adjusting screw rod of each fine adjusting mechanism is installed in a supporting hole on a machine body. The fine adjusting mechanism and the fine adjusting screw rod are assembled to form a high-precision sliding bearing. A graduated disc is connected with the fine adjusting screw rod through a spiral pin bolt in fastening mode. A wear-resisting liner is arranged between each fine adjusting screw rod and the machine body. Threaded bushings are respectively embedded on sliding blocks and respectively and fixedly connected with screws through locating pins. Vertical sliding blocks and horizontal sliding blocks are connected in embedded mode. Size adjustment of the four-roll rolling forming machine is achieved through the sliding blocks which accurately guide mutually perpendicular slide ways in a cavity of the machine body. Moreover, only guiding in the horizontal or vertical direction can be carried out. The fine adjusting mechanisms drive nuts and the sliding blocks to move through rotation of a threaded rod so as to achieve adjustment of high-precision position distance.

Technical field
The utility model relates to bimetal saw blade high speed steel-tooth material roll forming equipment, the particularly guiding mechanism of four rolling system make-up machines.
Background technology
Bi-metal bandsaw blades is a kind of novel cutting tools, in order to save the saw blade cost and to satisfy metal sawing requirement, adopts bimetallic to make.Backing is medium carbon steel RM80, and fatigue resistance is high, and the tooth material is high-speed steel M42, contains cobalt amount 8%, and hardness HRC64-67 has high-wearing feature and high red hardness, and sawtooth is easy fracture not, long service life, and cost hangs down characteristics.
The high speed steel-tooth material of bi-metal bandsaw blades is a roll forming, through laser beam bimetallic is welded.Four rolling system make-up machines are one of visual plants on the high speed steel-tooth material rolling line.The high speed steel blank of hardness HRC22-24,, form high speed steel-tooth material through pulling equipment through the rolling of four hard alloy rolls.Its operation principle is that four hard alloy rolls are adjusted into the rectangle shaping mould, can satisfy the processing of plurality of specifications size product.The specification of common high speed steel-tooth material: width 0.6-1.5mm, height 2.5-5mm.The product tolerance is+/-0.005mm.
The four rolling system make-up machines that use at present, because design defect, rolling high speed steel-tooth material dimensional accuracy is overproof.Main cause is that the design of product size precision guiding mechanism is unreasonable.The fine setting leading screw of controlling dimension precision adopts angular thread, and in process of production, self-locking performance is poor, causes dimensional accuracy control inaccuracy.It is inconsistent to cause high speed steel-tooth material size to occur, dimensional accuracy greater than+/-0.015mm, can not satisfy the specification requirement of product.
The utility model content
The purpose of the utility model overcomes above-mentioned not enough problem exactly; A kind of guiding mechanism of four rolling system make-up machines is provided, simple and reasonable, through the improvement design of mechanism; Satisfy the accurate to dimension requirement of bi-metal bandsaw blades high speed steel-tooth material; Guarantee the product line continuous operation, guarantee product quality, enhance productivity.
The utility model for realizing the technical scheme that above-mentioned purpose adopts is: the guiding mechanism of four rolling system make-up machines; Relate to roll, adjustment screw seat and micro-adjusting mechanism, roll is installed in the roll bearing seat, and adjustment screw seat is installed in rotation on the roll bearing seat; Level and vertical direction are equipped with a micro-adjusting mechanism respectively in four rolls; Said micro-adjusting mechanism mainly is made up of alignment pin, spiral pin, dial, body, unworn liner, fine setting leading screw, screw-thread bush, bolt, slide block, and the fine setting leading screw is installed in the support holes of body, and both assemble the back and form high-accuracy sliding bearing; Dial is connected through the screw pin staple with the fine setting leading screw; Between fine setting leading screw and the body unworn liner is installed, screw-thread bush is embedded on the slide block, and is fixedly connected with screw through alignment pin; Vertical slipper is embedded the connection with cross sliding clock.
The connection screw thread of said fine setting leading screw and screw-thread bush adopts trapezoidal thread.
The utility model four rolling system make-up machine size adjusting are to accomplish through slide block vertical each other slideway of accurate guiding in the body die cavity; And can only carry out the guiding of level or vertical direction, micro-adjusting mechanism drives the adjustment that realizes the high precision position distance of moving of nut and slide block through rotating screw bolt.When rotating the fine setting leading screw, screw-thread bush drive slide block moves along the guide slide of body, so just produces the distance of positions.Realize the coffin size adjusting of four hard alloy rolls, reach desired dimensional accuracy, constitute dimensional accuracy control micro-adjusting mechanism like this, the control accuracy of its design is 0.01mm.
Fine setting leading screw and two parts of screw-thread bush carry out Quenching Treatment.Wherein finely tuning leading screw hardness is HRC42-45, and the hardness of screw-thread bush is HRC38-40, improves the mechanical strength and the wearability of two parts like this.The technology of fine finishining trapezoidal thread after the employing heat treatment, the surface roughness of assurance threaded portion has been guaranteed trapezoidal thread good binding degree.Connection screw thread in the dimensional accuracy control micro-adjusting mechanism is selected trapezoidal thread for use.Trapezoidal thread has the advantages that transmission torsion is big, self-locking performance is good.Can guarantee that micro-adjusting mechanism can not become flexible at work, thus the functional reliability of the equipment of assurance.
Description of drawings
