Abstract
The utility model discloses a pressure head for a bend. The pressure head comprises a pressure head body and magnetic steel, wherein the pressure head body is provided with a bend placing groove; and the magnetic steel is embedded into the top and the side wall of the bend placing groove, and attracts the bend during loading. The pressure head is characterized by also comprising a limit block, an adjusting jackscrew, screws and a locking nut, wherein the limit block is fixedly arranged on the end face of the workpiece bend placing groove on the pressure head body through the screws; the thread internal diameter of the adjusting jackscrew is greater than that of a workpiece bend end contact surface; the adjusting jackscrew is in threaded connection with the limit block; before press mounting force is applied, a fit clearance is formed between the end face of the adjusting jackscrew and the workpiece bend end contact surface; the adjusting jackscrew is locked on the limit block through the locking nut; and after the press mounting force is applied, the bend is stressed and slightly deformed, and the end face of the adjusting jackscrew applies pressure to the workpiece bend end contact surface to clamp a workpiece. The pressure head has a simple structure and is easy to adjust; the bend without a step surface can be subjected to press mounting, and the bend is slightly deformed or is not deformed after being subjected to press mounting; and the bend is not required to be provided with the step surface, so that the manufacturing cost of the bend is reduced.
Description
Technical field
The utility model belongs to the frock technical field, relates to a kind of bend pipe pressure head, and the bend pipe that both had been applicable to step surface press-fits, and is applicable to again press-fit without the step surface bend pipe; Be particularly useful for press-fiting without the step surface bend pipe.
Background technology
As everyone knows, when the bend pipe that press-fits without step surface, pressure assembling force is applied directly on the bend pipe, easily causes the distortion of bend pipe caliber or angle of bend to change.
As shown in Figure 1: for having press-fiting of step surface bend pipe, pressure head structure is simple, and its structure comprises pressure head body 1 and magnet steel 2; Pressure head body 1 has a bend pipe workpiece putting groove, the groove of workpiece bend pipe 7a putting groove top and groove sidewall setting-in magnet steel 2 on the pressure head body, and magnet steel 2 holds workpiece bend pipe 7a during material loading; Pressure head body 1 pressing surface axially contacts with the bend pipe step surface; Can be born by workpiece bend pipe 7a step surface the pressure assembling force of bend pipe pressure head.
Bend pipe for without step surface press-fits difficulty; How designing a kind of bend pipe pressure head, when making the bend pipe that press-fits without step surface, avoid pressure assembling force to cause the distortion of bend pipe caliber or angle of bend to change, is the solution that engineers and technicians seek.
Summary of the invention
The utility model discloses a kind of bend pipe pressure head, press-fits difficulty to solve in the prior art without the step surface bend pipe, easily causes the problems such as the distortion of bend pipe caliber or angle of bend variation.
Technical solution of the present utility model is as follows: comprise pressure head body and magnet steel, the pressure head body has a bend pipe putting groove, the groove of workpiece bend pipe putting groove top and groove sidewall setting-in magnet steel on the pressure head body, and magnet steel holds bend pipe during material loading; It is characterized in that: also comprise limited block, adjust jackscrew; Limited block is fastening to be installed in workpiece bend pipe putting groove end face on the pressure head body; Adjust the jackscrew bottom diameter greater than workpiece bend pipe end in contact face; Adjusting jackscrew is threaded with limited block; Before not executing pressure assembling force, has fit clearance between adjustment jackscrew end face and workpiece bend pipe end in contact face; After executing pressure assembling force, the stressed rear little distortion of bend pipe is adjusted the jackscrew end face and is pressed on workpiece bend pipe end in contact face clamping holding workpiece; Adjust the jackscrew end face and highly determine the little deflection of bend pipe after stressed in the back-out on the limited block.
The utility model also comprises screw, locking nut; Screw is installed on the pressure head body limited block is fastening; When adjusting the jackscrew end face after the back-out on the limited block is highly determined, will adjust jackscrew by locking nut and be locked on the limited block, prevent from adjusting jackscrew loosening in the course of the work.
During work, the pressure head body is connected on the principal axis of pressing machine, at first fills in the bend pipe putting groove that bend pipe is put into the pressure head body, and magnet steel holds bend pipe; The pressure head body drives downward motion by forcing press, bend pipe is pressed in the bend pipe mating holes that cooperates workpiece; After bend pipe was pressed into, forcing press band dynamic head return was finished a bend pipe and is press-fited.
Good effect of the present utility model is: simple in structure, easily adjust; Can press-fit without the step surface bend pipe, press-fit back elbow few without distortion; Make bend pipe remove the step surface design from, reduce the manufacturing cost of bend pipe.
Description of drawings
Fig. 1: be existing bend pipe pressure head structure schematic diagram;
Fig. 2: be the utility model bend pipe pressure head structure schematic diagram;
Among the figure: 1 pressure head body, 2 magnet steel, 3 limited blocks, 4 are adjusted workpiece bend pipe that jackscrews, 5 screws, 6 locking nuts, 7a have step surface, 7b without the workpiece bend pipe of step surface.
The specific embodiment:
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 2: the utility model comprises pressure head body 1, magnet steel 2, limited block 3, adjusts jackscrew 4, screw 5, locking nut 6; Pressure head body 1 has a bend pipe putting groove, two blocks of magnet steel 2 of groove top setting-in of workpiece bend pipe putting groove on the pressure head body 1, magnet steel 2 of groove sidewall setting-in of workpiece bend pipe putting groove on the pressure head body 1; Limited block 3 is fastening to be installed in workpiece bend pipe putting groove end face on the pressure head body 1; Screw 5 is with limited block 3 fastening being installed on the pressure head body; Adjusting jackscrew 4 is threaded with limited block 3; Adjust jackscrew 4 and can precession regulate the fit clearance of adjusting before jackscrew 4 end faces are not executed pressure assembling force with workpiece bend pipe end in contact face on limited block 3, adjustment jackscrew 4 bottom diameters are greater than workpiece bend pipe end in contact face; Execute the stressed rear little distortion of pressure assembling force back elbow, adjust jackscrew 4 end faces and press on workpiece bend pipe end in contact face, clamp holding workpiece; Adjust jackscrew 4 end faces and highly determine the little deflection of bend pipe after stressed in the back-out on the limited block 3.When adjusting jackscrew 4 end faces after the back-out on the limited block 3 is highly determined, will adjust jackscrew 4 by locking nut 6 and be locked on the limited block 3, prevent from adjusting jackscrew 4 loosening in the course of the work.
The outboard end of adjusting in the present embodiment jackscrew 4 has handle, and the convenient adjusting of adjusting jackscrew 4 screws.
