Drawings
Fig. 1 is a schematic structural view of the stroke-adjustable punching oil cylinder of the present invention;
the hydraulic cylinder comprises a cylinder body 1, a piston rod 2, a stamping head 3, a limiting ring block 4, a butting block 5, a rotating handle 6, a rear cover 7, a first oil port 8, a guide sleeve 9, a clamping piece 10, a pressing cover 11 and a second oil port 12.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, a novel stroke-adjustable stamping oil cylinder, including cylinder body 1, slidable mounting has piston rod 2 in the cylinder body 1, 2 lower extremes of piston rod are fixed with stamping head 3, be provided with the external screw thread on the 1 circumference outer wall of cylinder body, install spacing ring piece 4 on the 1 circumference outer wall of cylinder body, spacing ring piece 4 and 1 screw-thread fit of cylinder body, stamping head 3 is provided with butt joint piece 5 toward 4 directions extensions of spacing ring piece along the 1 outer wall of cylinder body.
Furthermore, a rotating handle 6 is fixed on the periphery of the limit ring block 4.
Further, a rear cover 7 is fixed at the upper end of the cylinder body 1, a first oil port 8 is formed in the rear cover 7, the first oil port 8 is communicated with the rodless cavity side of the cylinder body 1, and a second oil port 12 is formed in the cylinder body 1.
Further, a guide sleeve 9, a clamping piece 10 and a gland 11 are arranged on the inner wall of the lower end of the cylinder body 1 from top to bottom, and the piston rod 2 penetrates through the guide sleeve 9 and the gland 11.
Further, an inner cylinder groove is formed in the inner wall of the cylinder body 1, a guide sleeve step is formed in one end of the outer wall of the guide sleeve 9, and the clamping piece 10 is clamped in the inner cylinder groove and the guide sleeve step.
Further, the pressing cover 11 is fixedly connected with the guide sleeve 9 through a bolt.
When the stroke-adjustable punching oil cylinder of the utility model is produced and assembled, referring to fig. 1, firstly, the limiting ring block 4 is sleeved on the cylinder body 1 from the lower end of the cylinder body 1, and is installed in a rotating fit with the external thread on the surface of the cylinder body 1, and the rotating handle 6 is fixed on the limiting ring block 4; installing the piston rod 2 in the cylinder body 1, and moving the piston rod 2 upwards to the uppermost end; the guide sleeve 9 is placed in the cylinder body 1 and sleeved on the piston rod 2 to move upwards; the clamping pieces 10 are single independent small blocks, a plurality of clamping pieces 10 are placed in an inner cylinder body groove formed in the inner wall of the cylinder body 1, the guide sleeve 9 is moved downwards, and guide sleeve steps formed in the lower end of the outer wall of the guide sleeve 9 are correspondingly matched with the clamping pieces 10; install gland 11 in cylinder body 1 again, through bolt and guide pin bushing 9 fixed connection, and then fix guide pin bushing 9, fastener 10, gland 11 and cylinder body 1.
Referring to fig. 1, when adjusting the stroke, the piston rod keeps stretching out, and operating personnel holds the twist grip 6, and the rotation control stop ring piece 4 moves down for cylinder body 1, and the punching stroke diminishes, and during operation, when piston rod 2 moved up, butt 5 and the 4 butt of stop ring piece of punching press head 3 reached the last stroke limit point of punching stroke.
