Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.
As shown in fig. 1, 2 and 3, the bending mechanism for a machine cover welding part of the present invention comprises a die sleeve, wherein the die sleeve is in a sleeve shape; the mold comprises a mold sleeve 1 and is characterized in that a module 3 is installed at the bottom of the inner ring surface of the mold sleeve 1, the module 3 is semi-annular, the module 3 is inverted, a welding piece 4 is placed on the top of the module 3 in a mirror image mode, a leading-in cavity is reserved between the welding piece 4 and the center of the module 3, a composite roller 2 is horizontally inserted into the leading-in cavity, and a pushing key 12 protruding from the tail of the composite roller 2 is in pushing contact with the welding piece 4 and the inner side surface of the module 3. Wherein, the worker puts the module 3 upside down in advance on the inner circle face of the bottom of the die sleeve 1, and then stacks the welding part 4 with certain radian in the module 3; forming a structure with upper and lower mirror images. And starting the air cylinder 6, driving the composite roller 2 to be inserted into the guide-in cavity, and driving the ejector key 12 protruding from the tail part of the composite roller 2 to finish the expansion bending process of the welding part 4. Because the die sleeve 1 is of a uniform sleeve structure, when the welding part 4 finishes the bending process, the formed radian and size are consistent with those of the die piece 3.
As shown in figures 1 and 3, the module 3 comprises a step layer 3-1 and a block forging layer 3-3, wherein a lug 3-2 is left on the outer end surface of the block forging layer 3-3, and the lug 3-2 is selectively embedded in an inner groove 1-1 of the inner ring surface of the die sleeve 1. The embedded head forging layer 3-3 of the module 3 is formed by being matched with the welding piece 4 in a stamping mode, so that the welding piece 4 is kept in the same position with the module 3 and is in an assembled structure with the embedded head forging layer 3-3, and the hood can be welded and used conveniently in the later period. The bump 3-2 structure is convenient for bending and positioning and can quickly finish the later processing procedure. And the convex block 3-2 is convenient for the later-stage welding piece 4 to be matched with the hood for welding. Meanwhile, the projection 3-2 is already on the welding part 4 during the bending process.
As shown in figure 1, a reset piece 5 is arranged in an inner groove 1-1 at the bottom of a die sleeve 1, and the reset piece 5 is elastically clamped with a convex block 3-2 on the outer ring surface of the die sleeve 3. Wherein, the reset piece 5 is a pair of telescopic pipes which are convenient for clamping installation and are internally provided with springs.
