Abstract
The invention relates to a double-support pressurizing mechanism, which comprises two symmetric ejector rods connected to two ends of an upper punch. The lower portion of each ejector rod drives a rotatable shifting fork stopper through a cylinder, equal-height support adjusting screw rods are arranged below the shifting fork stoppers, an open rod capable of contacting with each shifting fork stopper is arranged between each cylinder and the shifting fork stopper, and a mechanism for preventing a female die from descending is formed when the two shifting fork stoppers are supported on the support adjusting screw rods. By the aid of a two-side symmetric structure of the double-support pressurizing mechanism, pressure is evenly distributed on the double support adjusting screw rods, main pressing force is decomposed into component force, a pressure stress on the mechanism is decomposed into two smaller pressure stresses, the requirements of part materials and heat treatment are lowered on the premise of meeting functional requirements, and the functions of a single large-sized structure are realized by a structure of a smaller size.
Description
Technical field
The present invention relates to a kind of double base pressing mechanism, belong to the sintered metal product technical field.
Background technology
Pulverulent product is in forming process, and after goods pressurizeed on accomplishing and secondary pressurizes, goods intermediate density and two ends had than big-difference, in order to improve the goods intermediate density, must carry out the purpose that pressurize for the third time to realize that the goods intermediate density improves to goods; Existing pressing mechanism often is a single structure; Be that its total press power is born by a pressing mechanism; This has proposed higher requirement to the mechanical performance and the mechanical property of pressing mechanism itself undoubtedly; It is damaged after using a period of time easily, can influence the Forming Quality and the production cost that improves goods of goods, need improve.
Summary of the invention
The objective of the invention is to above-mentioned defective; Purpose is to provide a kind of total press power is decomposed; Reduction is to the requirement of single pressing mechanism, thereby the realization of ability long period can keep the stability and the conforming double base pressing mechanism of goods to three pressurizations of goods.
The technical scheme that adopts of the present invention is for this reason: the present invention includes to be connected and be symmetrically arranged two knockout pins towards two ends; The knockout pin bottom is through an air cylinder driven one rotating shift fork block; The supporting adjusting screw(rod) of high settings such as each shift fork block has is established the bar of opening that can contact with the shift fork block between cylinder and the shift fork block; Form when being bearing on the supporting adjusting screw(rod) between the two shift fork blocks and stop the descending mechanism of former.
Advantage of the present invention is: both sides of the present invention symmetrical structure makes on the support adjusting screw(rod) that is distributed in double base of isostasy; Total press power is decomposed into two component; Compression in the mechanism is decomposed into two less compression; Satisfy requirement, the heat treatment requirements that has reduced part material under the prerequisite of function, realizing the function of single large scale structure with the structure of reduced size.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 regulates worm couple, 9 for supporting adjusting screw(rod), 8 for supporting for lifting force cylinder, 7 for shift fork block, 6 and is the driving crossbeam for opening bar, 5 for pressure head, 4 for shift fork block reset cylinder, 3 for knockout pin, 2 among the figure.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation:
The present invention is after pressurization on the goods and secondary pressurization, and the former that is fixed together and driving crossbeam 9 are bearing on the high supporting adjusting screw(rod) 7 such as both sides by shift fork block 5 after moving downward a segment distance.Utilize shift fork block 5 and supporting adjusting screw(rod) 7 that descending former is stopped, last punch continues to press down, thereby forms three pressurizations to goods, forms until pressurization to finish.Pressurization finishes the back under demoulding action of cam, and the knockout pin 1 descending shift fork block 5 of opening makes it and support adjusting screw(rod) 7 disengagement realization demoulding functions, accomplishes the final molding of goods.
Knockout pin 1 of the present invention is opened bar 4 actions through the effect drive of concora crush head 3, shift fork block reset cylinder 2 in descending process, realize stopping former; The present invention simultaneously realizes shift fork block 5, the adjustment of supporting adjusting screw(rod) 7 on lengthwise position, to satisfy the instructions for use of varying environment through the adjustment of shift fork reset cylinder 2, supporting adjusting worm couple 8.
The present invention realizes moving upward of knockout pin 1 and associated components through lifting force cylinder 6.
Claims (1)
1. double base pressing mechanism; It is characterized in that; Comprise being connected and be symmetrically arranged two knockout pins towards two ends; The knockout pin bottom is through an air cylinder driven one rotating shift fork block, and each shift fork block has the supporting adjusting screw(rod) that waits high setting, establishes the bar of opening that can contact with the shift fork block between cylinder and the shift fork block; Form when being bearing on the supporting adjusting screw(rod) between the two shift fork blocks and stop the descending mechanism of former.
