Abstract
The invention discloses a high-accuracy rebar cutting trolley which comprises a left support and a right support. Guide rods in up-down spacing are arranged between the left support and the right support, a trolley body is arranged between the guide rods, rollers in guiding-direction rolling fit with the guide rods are mounted at the upper end and the lower end of the trolley body respectively, a straight guide hole is formed in the middle of the trolley body and corresponds to a discharging port of a rebar traction mechanism, a cutting knife is arranged at the discharging end of the guide hole and driven by a cutting hydraulic cylinder in the rear of the cutting knife, a resetting spring is mounted at a piston rod extending-out end of the cutting hydraulic cylinder in a sleeved manner, operating signals of the cutting hydraulic cylinder is controlled by signals of a meter counting wheel of the traction mechanism, a fixing lug is arranged at the upper end of a rear end portion of the trolley body, a spring is connected on the fixing lug, the other end of the spring is fixed on the left support at the feeding end, and a rubber buffering block is mounted on the inner side face of the left support. The high-accuracy rebar cutting trolley is reasonable in structural design, cutting of length positions is realized by the cutting knife, and especially in a high-speed state, requirements on cutting accuracy can be guaranteed, and cutting operations can be ensured to be completed efficiently.
Description
Technical field
The present invention relates to reinforcing bar processing auxiliary equipment field, relate in particular to a kind of high accuracy bar cutting dolly.
Background technology
Existing steel bar cutoff mechanism is fixed, and arrive certain rice number at reinforcing bar, in the time of need to be to bar cutting, although the action of air cylinder driven cutoff tool than very fast, due to reinforcing bar in constantly conveying, although transporting velocity is lower, inefficiency, but cutting off precision still can exist certain error, for the high-precision occasion of dimensional requirement, bring certain difficulty to subsequent operation or use, can not meet the requirement that the high accuracy batch machining is produced.
Summary of the invention
The objective of the invention is in order to make up the deficiency of prior art, a kind of high accuracy bar cutting dolly is provided.
The present invention is achieved through the following technical solutions:
A kind of high accuracy bar cutting dolly, include a left side, right support, it is characterized in that: a described left side, between right support, set up between the upper and lower every guide rod, be provided with car body between described guide rod, the upper and lower side of described car body is separately installed with and guide rod orienting roll roller movingly, described car body middle part is provided with pilot hole anyhow, described pilot hole is corresponding with the steel bar traction mechanism discharging opening, the discharge end of described pilot hole is provided with cutoff tool, described cutoff tool is by the cut-out Driven by Hydraulic Cylinder at its rear, the piston rod external part of described cutting-off liquid cylinder pressure is set with return spring, the run signal of described cutting-off liquid cylinder pressure is by the signal controlling of the rice counting wheel of haulage gear, described car body rearward end upper end is provided with fixedly ear, be connected with spring on described fixedly ear, the described spring other end is fixed on the left socle of feed end, described left socle medial surface is equipped with damping rubber block.
The car body outer face of described pilot hole feed end is provided with groove, in described groove, is provided with pilot hole, in described pilot hole, coordinates the guide pin bushing with different size transfer passage is installed.
Its principle is: mobile reinforcing bar is through in the pilot hole in car body, there is certain interaction force between it, car body can have with the reinforcing bar of carrying the movement of certain displacement, and then by cutoff tool, its extension position is cut, particularly under fast state, both can guarantee the requirement of cutting accuracy, and can also guarantee that rupturing operation is high efficiency to complete simultaneously; In the moving process of described car body, by roller and guide rod, lead, after cut-out, restoring force by spring is resetted, carry out rupturing operation next time, by the structural design of damping rubber block, play the buffer limit effect, by coordinating in pilot hole, different guide pin bushings is installed, can meet the processing request of the reinforcing bar of different model, the scope of application is wide.
Advantage of the present invention is:
Reasonable in design of the present invention, cut its extension position by cutoff tool, particularly under fast state, both can guarantee the requirement of cutting accuracy, can also guarantee that rupturing operation is high efficiency completes simultaneously, and can meet the processing request of the reinforcing bar of different model, and the scope of application is wide.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is partial structurtes schematic diagram of the present invention.
