Abstract
The utility model discloses a linear mold selection device in the field of stamping machine tools. The linear mold selection device comprises a first cushion block correspondingly arranged at the lower end of a sliding block, wherein the section of the first cushion block is in an L shape, and one side of the L-shaped first cushion block is close to the lower side of the sliding block; the inner side of the L-shaped first cushion block is matched with a second cushion block, and the end part of the lower side of the first cushion block is propped against a first male mold push rod; the lower side of the second cushion block is propped against a second male mold push rod, and the sides of the first cushion block and the second cushion block are respectively connected with spherical joint bearings; a guide hole is formed in the center of a ball head of each spherical joint bearing, and the central line of each guide hole is parallel to the movement axis of the sliding block; one arm of a right-angle connecting rod is inserted into the guide hole in a sliding way, and the other arm of the right-angle connecting rod is connected with the end part of a piston rod of a mold selection cylinder; the mold selection cylinder is fixedly arranged on a supporting plate. The piston rod can be universally adjusted according to the trajectory of the first or second cushion block, so that the piston rod can not generate a radial force, and thus the cylinder can work more reliably.
Description
Technical field
The utility model relates to a kind of punch process lathe, particularly the mould selecting arrangement on a kind of press machine.
Background technology
Straight line mould model selection device of the prior art, comprise modeling pushing block and modeling cylinder, between modeling pushing block and modeling cylinder, by T shape piece, connect, T shape piece is freely placed in the T-slot on modeling pushing block, matched in clearance between the two, the piston rod of modeling cylinder and T shape piece are rigidly connected.Due to the needs of processing technology, the per tour of part modeling pushing block needs back and forth movement up to ten thousand times, and long-term work causes modeling pushing block and pushing block gathering sill contact-making surface to produce wearing and tearing, and the movement locus of pushing block changes.Modeling pushing block drives T shape piece to produce radial effect power to cylinder piston, and after long-term work, the weak link of cylinder piston rod easily ruptures, and has affected lathe reliability, is easy to cause workpiece to scrap, and maintenance cost is increased.
Utility model content
The purpose of this utility model is to provide a kind of straight line mould model selection device, makes cylinder operation more reliable.
The purpose of this utility model is achieved in that a kind of straight line mould model selection device, comprise that correspondence is arranged on the first cushion block of slide block lower end, the first cushion block section is L-shaped, L shaped one side of the first cushion block abuts in slide block downside, the L shaped inner side cooperation of the first cushion block is provided with the second cushion block, the downside end of the first cushion block is conflicted on punch push rod one, the downside of the second cushion block is conflicted on punch push rod two, described the first cushion block and the second cushion block side are connected with spherical joint bearing separately, the bulb center of spherical joint bearing is provided with pilot hole, the center line of pilot hole parallels with slide block movement axis, an arm of right angle connecting rod is inserted in described pilot hole slidably, another arm of right angle connecting rod is connected with the piston rod end of modeling cylinder, described modeling cylinder is fixed in gripper shoe.
In the utility model when work,, this straight line mould model selection device is set side by side with many groups, and the modeling cylinder by separately can promote the first cushion block and the second cushion block moves, and makes corresponding cushion block and corresponding punch push rod staggered positions, can select so different punch work.Owing to there being the setting of right angle connecting rod and spherical joint bearing, piston rod carries out universal adjustment according to the track of the first cushion block or the second cushion block, slide block is when promoting the first cushion block and the motion of the second cushion block, can relative sliding between right angle connecting rod and spherical joint bearing, avoid producing side direction and push piston rod, eliminate the effect of radial load to piston rod.Compared with prior art, the utility model makes cylinder operation more reliable, and this device is applicable to the modeling of straight line mould.
As further improvement of the utility model, between the piston rod of described right angle connecting rod and modeling cylinder, be threaded, piston rod is provided with sheath, smooth and the engage sleeves in sheath endoporus one end is contained on piston rod, and the sheath endoporus other end is threaded on piston rod and connecting rod end, jam-packed right angle.When sheath is locked right angle connecting rod, can protect the weak link of piston rod thread section, prevent from rupturing at thread root.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the another kind of working state schematic representation of the utility model.
Fig. 3 is the third working state schematic representation of the utility model.
Wherein, 1 slide block, 2 first cushion blocks, 3 second cushion blocks, 4 right angle connecting rods, 5 spherical joint bearings, 6 sheaths, 7 piston rods, 8 gripper shoes, 9 modeling cylinders, 10 punch push rod two, 11 punch push rods one.
The specific embodiment
As shown in the figure, for a kind of straight line mould model selection device, comprise that correspondence is arranged on the first cushion block 2 of slide block 1 lower end, the first cushion block 2 sections are L-shaped, L shaped one side of the first cushion block 2 abuts in slide block 1 downside, the L shaped inner side cooperation of the first cushion block 2 is provided with the second cushion block 3, the downside end of the first cushion block 2 is conflicted on punch push rod 1, the downside of the second cushion block 3 is conflicted on punch push rod 2 10, the first cushion block 2 and the second cushion block 3 sides are connected with spherical joint bearing 5 separately, the bulb center of spherical joint bearing 5 is provided with pilot hole, the center line of pilot hole parallels with slide block 1 axis of movement N, an arm of right angle connecting rod 4 is inserted in pilot hole slidably, another arm of right angle connecting rod 4 is connected through screw thread with piston rod 7 ends of modeling cylinder 9, modeling cylinder 9 is fixed in gripper shoe 8, piston rod 7 is provided with sheath 6, and the smooth and engage sleeves in sheath 6 endoporus one end is contained on piston rod 7, and the sheath 6 endoporus other ends are threaded on piston rod 7 and connecting rod 4 ends, jam-packed right angle.
During work, this straight line mould model selection device is set side by side with many groups, the first cushion block 2 and the second cushion block 3 that modeling cylinder 9 by separately can promote respectively to organize straight line mould model selection device move, make corresponding cushion block and corresponding punch push rod staggered positions, can select so different punch work, as Fig. 1, shown in 2 and 3, corresponding punch push rod 1 and punch push rod 2 10 are worked simultaneously respectively, only punch push rod 2 10 work, three kinds of duties of punch push rod 1 work only, slide block 1 is descending promotes corresponding punch pushrod movement, through punch push rod, promote corresponding punch motion, realize stamping-out processing, owing to there being the setting of right angle connecting rod 4 and spherical joint bearing 5, piston rod 7 carries out universal adjustment according to the track of the first cushion block 2 or the second cushion block 3, slide block 1 is when promoting the first cushion block 2 and the second cushion block 3 motion, can relative sliding between right angle connecting rod 4 and spherical joint bearing 5, avoid producing side direction and push piston rod 7, eliminate the effect of radial load to piston rod 7.
