Description

Technical Field

[0001] This utility model mainly relates to the technical field of punching heads for mechanical punch presses, specifically an improved quick-release punching head for mechanical punch presses. Background Technology

[0002] A mechanical punch press, also known as a mechanical stamping press, is an important metal processing equipment. It utilizes compressed air supplied by a compressed air pump, which enters the cylinder via a solenoid valve. This air drives the piston, transmitting power to the spindle, causing it to move downwards and generating punching force. This force causes the workpiece to undergo a predetermined deformation within the die, achieving the processing objective. Furthermore, the design principle of a mechanical punch press also includes converting circular motion into linear motion. Power from the main motor drives a flywheel, which, via a clutch, drives gears, a crankshaft (or eccentric gear), connecting rods, etc., thus achieving the linear motion of the slide block.

[0003] According to application number CN202322730336.0, a quick-release punch head for a mechanical punch press is provided. It includes a punching table, a support frame mounted on the upper end of the punching table, a cylinder mounted on the bottom end of the support frame, a punch head body mounted on the output end of the cylinder, and a base mounted on the bottom end of the punching table; an adjusting device is installed on the arc surface of the punch head body, the adjusting device includes a fixed ring, three rotating rods uniformly rotatably connected to the arc surface of the fixed ring, a positioning ring fixedly connected to the arc surface of the cylinder corresponding to the position of the fixed ring, and a positioning block fixedly connected to the surface of the positioning ring corresponding to the position of the rotating rod, the positioning block having a "U" shaped cross-section.

[0004] In the above structure, the structural strength between the fixed ring, rotating rod and positioning ring is insufficient when they are connected, which can easily cause damage during the operation of the mechanical punch. Based on the above problems, the quick-release structure is improved and optimized. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an improved quick-release punching head for mechanical punching machines to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved quick-release punch head for a mechanical punch press includes a connecting mechanism disposed on the top of the side wall of the punch head. The connecting mechanism includes a first connecting plate, a connecting rod passing through one bottom end of the first connecting plate, a second connecting plate sleeved on the top of the connecting rod and located above the first connecting plate, a chuck disposed on the top of the second connecting plate, and a limiting latch disposed on one top end of the chuck.

[0008] Preferably, the bottom of the first connecting plate is provided with a first mounting hole; the inner wall of the first mounting hole is slidably connected to the bottom of the side wall of the connecting rod.

[0009] Preferably, the bottom of the connecting rod is provided with a locking ball, and the top of the connecting rod is threadedly connected with a limiting nut.

[0010] Preferably, the second connecting plate is provided with reinforcing ribs at both the top and bottom, the bottom of the second connecting plate is provided with a second mounting hole, and the top of the second connecting plate and located on one side of the reinforcing rib is provided with a retaining rail.

[0014] In summary, this technical solution has the following main advantages:

[0015] In this invention, the connecting rod, the first connecting plate, and the second connecting plate form a connecting mechanism, enabling quick disassembly of the stamping head. The cooperation between the chuck and the limiting nut further increases the connection stability of the connecting mechanism, adapting to the long-term operation of the stamping head and resulting in higher structural strength. In addition, the limiting nut provides auxiliary fixation to the chuck, further increasing the overall stability of the connecting mechanism. The overall structure of the connecting mechanism is reasonable and easy to use. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example

[0023] like Figures 1 to 4 As shown, an improved quick-release punch head for a mechanical punch press includes a connecting mechanism 10 located on the top of the side wall of the punch head. The connecting mechanism 10 includes a first connecting plate 11, a connecting rod 12 passing through one bottom end of the first connecting plate 11, a second connecting plate 13 sleeved on the top of the connecting rod 12 and located above the first connecting plate 11, a chuck 14 located on the top of the second connecting plate 13, and a limiting latch 15 located on one top end of the chuck 14.

[0024] It should be noted that, in this embodiment, the bottom of the first connecting plate 11 is provided with a first mounting hole 111; the inner wall of the first mounting hole 111 is slidably connected to the bottom of the side wall of the connecting rod 12.

[0025] The bottom of the connecting rod 12 is provided with a locking ball 121, the radius of which is larger than the radius of the second mounting hole 132, to limit the connecting rod 12 and prevent it from passing through the second mounting hole 132. The top of the connecting rod 12 is threadedly connected with a limit nut 122.

[0026] The second connecting plate 13 is provided with reinforcing ribs 131 at both the top and bottom. The bottom of the second connecting plate 13 is provided with a second mounting hole 132. The top of the second connecting plate 13 and the side of the reinforcing rib 131 are provided with a retaining rail 133.

[0027] One end of the chuck 14 is provided with a U-shaped groove 141, the other end of the chuck 14 is provided with a through hole 142, and square strips 143 are provided on both sides of the chuck 14.

[0028] The square bar 143 is slidably connected to the inner wall of the chuck 133, which is used to limit the movement of the chuck 14.

[0029] The limit button 15 is threadedly connected to the through hole 142 to fix the chuck 14.

[0030] The working principle of this utility model is as follows:

[0031] In the connecting mechanism 10, the second connecting plate 13 is located at the execution end of the mechanical punch, and the first connecting plate 11 is located at the punch head. When the punch head needs to be installed on the execution end of the mechanical punch, the top of the punch head is first inserted into the bottom of the execution end of the mechanical punch. Then, the threaded end of the connecting rod 12 is turned upward and passed through the first mounting hole 111 at the bottom of the first connecting plate 11 and the second mounting hole 132 at the bottom of the second connecting plate 13. The connection is pre-fixed by using the limit nut 122. The other first mounting holes 111 and second mounting holes 132 are also pre-fixed by the same operation.

[0032] Subsequently, by pushing the chuck 14 so that one end of the chuck 14 with the U-shaped groove 141 is embedded in the side wall of the connecting rod 12, and at the same time, the limiting nut 122 and the limiting buckle 15 are further tightened to further limit and fix the chuck 14. The fixation of the chuck 14 restricts the movement of the connecting rod 12 on the one hand, and cooperates with the limiting nut 122 to push the bottom of the limiting nut 122, restricting the rotation of the limiting nut 122, and further increasing the stability of the connecting rod 12.

[0033] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
