Description

Technical Field

[0001] The utility model relates to the technical field of cold heading clamps, and particularly relates to an independent cold heading clamp mechanism. Background Art

[0002] At present, the cold heading clamp is an important component on the cold heading machine, and its main function is to clamp and transfer workpieces during the cold heading forming process.

[0003] In the prior art, there is an independent cold heading machine clamp mechanism with the authorized announcement number of CN219211492U. This patent includes key components such as a clamp seat, a fixed frame, a cylinder, a connecting rod, a guide post, a rotating shaft, a first connecting plate, and a first guide groove. Specifically, the clamp seat serves as the foundation of the entire mechanism, and a fixed frame is firmly connected to its bottom to provide stable support for the entire mechanism. The outer wall of the top of the clamp seat is fixedly connected with a cylinder. One end of the piston rod of this cylinder passes through the clamp seat and is fixedly connected with a connecting rod. This connecting rod is slidably connected to the fixed frame, enabling the cylinder to move up and down stably and smoothly when driving the connecting rod. The bottom end of the connecting rod is fixedly connected with a guide post, which plays a key guiding role during the operation of the mechanism. On the inner wall of one side of the fixed frame, a rotating shaft is rotatably connected. A first connecting plate is fixedly connected to the outside of this rotating shaft. Inside this first connecting plate, a first guide groove is opened for precise guiding control in cooperation with the guide post. This design can not only make the two clamp pieces stably clamp objects, thereby improving the stability of the clamp pieces, but also cleverly assist in clamping objects through an elastic plate, significantly enhancing the clamping effect of the objects. More importantly, this mechanism is also equipped with a pointer and a scale, and the combined use of the two enables the staff to intuitively understand the distance between the bottoms of the two clamp pieces, which undoubtedly greatly improves the flexibility and convenience of use of the device.

[0004] However, when this patent is in use, it can only clamp workpieces with a single shape, and because there are no protective parts during clamping, it is easy to damage the outside of the cold heading parts during clamping, resulting in poor protection. Moreover, when this patent is in use, the cold heading parts will generate a certain amount of heat just after processing, and it is impossible to cool them, resulting in a single function.

[0045] Embodiment 1:

[0046] As Figures 1 to 4As shown in the figure, the present utility model provides an independent cold heading clamp mechanism, which includes a main frame body 101 and a clamping frame body 10. An auxiliary mechanism 2 is installed inside the main frame body 101, and a clamping mechanism 1 is installed inside the clamping frame body 10;

[0047] The clamping mechanism 1 includes a clamping component 11 and a multi-position fixing component 12. The clamping component 11 is installed inside the clamping frame body 10, and the multi-position fixing component 12 is installed inside the clamping frame body 10. The auxiliary mechanism 2 includes a position adjustment component 21, a temperature reduction component 22, and an external connection component 23. The position adjustment component 21 is installed inside the main frame body 101, the temperature reduction component 22 is sleeved inside the main frame body 101, and the external connection component 23 is fixedly connected to one side of the main frame body 101;

[0048] Among them, the clamping component 11 includes a sliding cylinder 111, a left clamping block 119, and a right clamping block 118. The sliding cylinder 111 is installed inside the clamping frame body 10. The output end of the sliding cylinder 111 is installed with a sliding shaft 112. One end of the sliding shaft 112 is fixedly connected to a sliding frame 113. A partition limiting plate 114 is fixedly connected inside the sliding frame 113. A connecting column 115 is fixedly connected inside the sliding frame 113 and the partition limiting plate 114. An upper hinge block 117 and a lower hinge block 116 are respectively movably sleeved on the outer peripheral surface of the connecting column 115. The left clamping block 119 and the right clamping block 118 are respectively fixedly connected to one end of the upper hinge block 117 and the lower hinge block 116. Through grooves are respectively opened inside the upper hinge block 117 and the lower hinge block 116. The connecting column 115 is slidably assembled inside the through grooves.

[0049] As Figures 1 to 4 shown, the multi-position fixing component 12 includes a plurality of sliding blocks 121 evenly distributed in a circle. The plurality of sliding blocks 121 are respectively slidably connected inside the left clamping block 119 and the right clamping block 118. One side of the sliding block 121 is fixedly connected to a multi-angle fixing block 122. One side of the sliding block 121 is connected to a return spring 123. One ends of the plurality of return springs 123 are respectively connected to the inner walls of the left clamping block 119 and the right clamping block 118.

[0050] Among them, grooves are respectively opened inside the left clamping block 119 and the right clamping block 118. The plurality of sliding blocks 121 are respectively slidably connected inside the two grooves. The clamping inner wall shape of the multi-angle fixing block 122 is trapezoidal, and the angle between its two clamping sides relative to the middle clamping side is 165 degrees.

[0051] Embodiment 2:

[0052] As Figures 1 to 4As shown in the figure, on the basis of Embodiment 1, the position adjustment component 21 includes a rotation motor 211 and a follower shaft 214. The rotation motor 211 is installed inside the main frame 101, and the follower shaft 214 is rotatably installed inside the main frame 101. The output end of the rotation motor 211 is connected by a coupling to a coaxial rotation shaft 212. One end of the rotation shaft 212 is fixedly connected to a driving gear 213. A follower gear 215 is fixedly sleeved on the outer peripheral surface of the rotation shaft 212. The driving gear 213 meshes with the follower gear 215. Both ends of the follower shaft 214 are fixedly connected to threaded rods 216. Threaded sleeves 217 are sleeved on the outer peripheral surfaces of the threaded rods 216. The two threaded sleeves 217 are respectively fixedly connected to one side of two of the clamping frames 10.

[0053] In this embodiment, based on the same concept as in Embodiment 1, this embodiment proposes that before the device clamps, the rotation motor 211 can be turned on according to cold heading parts of different lengths. The rotation of the rotation motor 211 drives the rotation of the rotation shaft 212. The rotation of the rotation shaft 212 drives the rotation of the driving gear 213. The meshing of the driving gear 213 and the follower gear 215 drives the rotation of the follower shaft 214. When the follower shaft 214 rotates, the threaded rods 216 at both ends rotate. The thread directions of the two threaded rods 216 are opposite, so that the threaded sleeves 217 can expand and contract as needed, making it adaptable to cold heading parts of different sizes.

[0054] Embodiment 3:

[0055] As Figures 1 to 5 shown in the figure, on the basis of Embodiment 2, the cooling component 22 includes a cooling frame 221. The cooling frame 221 is fixedly sleeved on both sides of the main frame 101. Six symmetrically arranged axial flow fans 222 are installed inside the cooling frame 221.

[0056] As Figures 1 to 2 shown in the figure, the external connection component 23 includes an external connection plate 231. A number of externally threaded bolts 232 arranged in an array at equal distances are slidably assembled inside the external connection plate 231. An external cable 233 is installed on one side of the external connection plate 231.

[0057] In this embodiment, based on the same concept as in Embodiment 1 and Embodiment 2, during the use of the device, by turning on the axial flow fans 222 inside the cooling frame 221, the cold heading parts can be cooled. An external connection plate 231 is fixedly connected to one side of the main frame 101. The external connection plate 231 can be fixed to an external device through external screws, thereby fixing the entire device. Then, through the external cable 233, the electrical devices inside the device can be connected to external electrical devices, thereby achieving the effect of controlling the device and improving the functionality of the device.

[0058] Working principle: When the device is in use, place the three clamping frames 10 on one side where the cold heading parts need to be clamped, so that the left clamping block 119 and the right clamping block 118 are on both sides of the cold heading parts. Then, turn on the sliding cylinder 111. The start of the sliding cylinder 111 drives the sliding shaft 112 to slide. The sliding of the sliding shaft 112 causes the sliding frame 113 to retract backward. During the retraction of the sliding frame 113, the connecting column 115 slides in the through grooves inside the lower hinge block 116 and the upper hinge block 117. Through the setting of the partition limiting plate 114, the upper hinge block 117 and the lower hinge block 116 move towards the middle to clamp the cold heading parts. During the clamping process, through the setting of the multi-angle fixing block 122, cold heading parts of different shapes can be clamped. During clamping, through the setting of the return spring 123 and the sliding block 121, effective buffering can be carried out on the clamping parts of the cold heading parts during clamping, so as to protect the cold heading parts.

[0059] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
