Description

Technical Field

[0001] This utility model relates to the field of bolt production technology, specifically to a torsion shear type cold heading machine for bolts. Background Technology

[0002] A cold heading machine is a stamping machine used in mechanical manufacturing. The steel used to manufacture fasteners and connectors by cold heading is called cold heading steel, commonly known as rivet steel. Cold heading is a process that uses the plasticity of metal to form fasteners at room temperature. Using cold heading to manufacture fasteners is not only efficient and of good quality, but also saves materials and reduces costs.

[0003] According to a publicly disclosed cold heading machine for twist-shear bolts (publication number: CN221966690U), the machine includes a housing, a fixed plate fixedly installed in the middle of the inner cavity of the housing, a transverse groove on the left side of the top of the fixed plate, and a mold movably connected to the inner part of the top center of the fixed plate; two mounting plates, the bottom ends of which are fixedly installed to the top of the fixed plate; and a motion mechanism located on the left side of the top of the fixed plate. The motion mechanism includes a drive motor fixedly installed on the front of the mounting plate, and a threaded rod fixedly sleeved at the other end of the drive motor's output shaft. The other end of the threaded rod passes through the mounting plate and extends between the mounting plates, movably engaging with the front of the mounting plate. This technical solution solves the problem of manual positioning in the prior art. However, in this device, the interaction of the housing and fixed plates makes it difficult to achieve heat dissipation for the material in the mold, resulting in difficulty in removing the material after processing, which requires further improvement.

[0010] Furthermore, one end of the torsion spring is fixedly connected to the fixed rod, the other end of the torsion spring is fixedly connected to the inner wall of the square groove, and the end of the short rod away from the fixed rod is rotatably connected to the inner wall of the square groove. The above design is beneficial for the pressure plate to be reset by the torsion spring.

[0011] Furthermore, the airbag is located on the displacement trajectory of the pressure plate, and the end of the pressure plate away from the airbag is located on the displacement trajectory of the push rod. The push rod is L-shaped, and the chain is located at the opening of the dropper. The above design is beneficial for dripping oil onto the chain through the dropper.

[0012] Furthermore, there are two positioning frames, which are symmetrical to each other along the vertical central axis of the fixed plate. The positioning frames are L-shaped. One end of the lead screw passes through the second gear and is fixedly connected to the second gear. The other end of the lead screw passes through the third gear and is fixedly connected to the third gear.

The push rod and the fixed rod are located on the same horizontal line. The above design is beneficial for the push rod to push the pressure plate to rotate.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, the force of the motor-driven rotating rod is combined with the components such as the fixed frame and the limiting rod to realize the rotation of the rotating rod by the motor, thereby driving the rotating shaft to rotate, which in turn drives the fan blade to rotate, so that the fan blade rotates and blows air, achieving the effect of heat dissipation of the material in the mold, thus making it easier to remove the processed material from the mold.

[0018] 2. In this utility model, the force of gear rotation, in conjunction with components such as the fixed rod, push rod, and pressure plate, enables the rotating rod to drive the first gear on it to rotate when it rotates. This first gear then drives the chain to rotate, which in turn drives the second gear to rotate. The second gear then drives the push rod to rotate, which in turn pushes the pressure plate to rotate. This causes the pressure plate to compress the airbag, causing it to contract. When the pressure plate moves away from the airbag, the airbag expands due to the tension of its internal spring. This allows the airbag to draw oil from the oil tank into its interior through the connecting pipe. When the pressure plate compresses the airbag again, the airbag drips oil onto the chain through the dropper, thus achieving the effect of lubricating the components of the device.

A control component 102 is provided on one side of the device sleeve 101. A mold 103 is fixedly connected to the inner wall of the device sleeve 101. A fixing plate 104 is fixedly connected to one side of the device sleeve 101. An electric telescopic rod 105 is fixedly connected to the top of the fixing plate 104. A hydraulic component 107 is provided on the top of the mold 103. A positioning plate 106 is provided on one side of the hydraulic component 107.

[0031] The cold heading mechanism 1 is externally equipped with a heat dissipation device 2, which includes a motor 201. A fixing frame 202 is fixedly connected to one side of the motor 201. The end of the fixing frame 202 away from the motor 201 is fixedly connected to the side of the device sleeve 101 away from the control component 102. A heat dissipation groove 203 is provided on the side of the device sleeve 101 near the fixing frame 202. A limit rod 204 is fixedly connected to the inner wall of the heat dissipation groove 203. A rotating rod 205 is fixedly connected to the output shaft of the motor 201. The end of the rotating rod 205 away from the motor 201 is... A rotating rod 205 passes through and is rotatably connected to the limiting rod 204. A rotating shaft 206 is fixedly connected to the end of the rotating rod 205 away from the motor 201. A fan blade 207 is fixedly connected to the circumferential surface of the rotating shaft 206.

[0032] The number of molds 103 is several, arranged in pairs, and arranged in a linear array at the bottom of the inner wall of the device sleeve 101. The end of the electric telescopic rod 105 away from the fixed plate 104 is fixedly connected to the bottom of the positioning plate 106. The above design is conducive to the vertical displacement of the positioning plate 106 by the electric telescopic rod 105.

[0033] There are four limiting rods 204, arranged in pairs and symmetrical to each other along the vertical central axis of the device sleeve 101. The rotating shaft 206 is located between two limiting rods 204. There are four gears 208, arranged in pairs and symmetrical to each other along the vertical central axis of the device sleeve 101.

A short rod 305 is inserted through one side and fixedly connected to the short rod 305. A torsion spring 306 is fixedly sleeved on the outer surface of the short rod 305. An air bladder 307 is provided below the pressure plate 303. A connecting pipe 309 is fixedly inserted through the circumference of the air bladder 307. An oil tank 310 is fixedly inserted through the end of the connecting pipe 309 away from the air bladder 307. A one-way valve 311 is provided at the end of the connecting pipe 309 near the oil tank 310. A dropper 312 is fixedly inserted through the circumference of the air bladder 307. A spring 308 is fixedly connected to the inner wall of the air bladder 307. The above design is beneficial for lubricating the components in the device.

[0037] One end of the torsion spring 306 is fixedly connected to the fixed rod 301, and the other end of the torsion spring 306 is fixedly connected to the inner wall of the square groove 304. The end of the short rod 305 away from the fixed rod 301 is rotatably connected to the inner wall of the square groove 304. The above design is conducive to the reset of the pressure plate 303 by driving the torsion spring 306.

[0038] The airbag 307 is located on the displacement trajectory of the pressure plate 303. The end of the pressure plate 303 away from the airbag 307 is located on the displacement trajectory of the push rod 302. The push rod 302 is L-shaped. The chain 211 is located at the opening of the dropper 312. The above design is conducive to dripping oil onto the chain 211 through the dropper 312.

[0039] There are two positioning frames 210, which are symmetrical about each other along the vertical central axis of the fixing plate 104. The positioning frame 210 is L-shaped. One end of the lead screw 209 passes through the second gear 208 and is fixedly connected to the second gear 208. The other end of the lead screw 209 passes through the third gear 208 and is fixedly connected to the third gear 208. The above design is conducive to positioning the lead screw 209 by using two positioning frames 210.

[0040] There are two chains 211, which are symmetrical to each other along the vertical central axis of the device sleeve 101. The mold 103 is located at the opening of the square groove 304. There are two square grooves 304, which are symmetrical to each other along the vertical central axis of the device sleeve 101. The above design is conducive to driving the remaining gears 208 to rotate through the chain 211.

[0041] The first gear 208 is located between the first limiting rod 204 and the motor 201. The fixed frame 202 is L-shaped, and the positioning plate 106 is located between the two chains 211. The above design helps to avoid the positioning plate 106 from colliding with the chain 211 when it descends.

The push rod 302 and the fixed rod 301 are located on the same horizontal line. The above design is conducive to the push rod 302 being able to push the pressure plate 303 to rotate.

[0043] In this embodiment, the rotation of the second gear 208 causes the push rod 302 to rotate, which in turn causes the push rod 302 to push the pressure plate 303 to rotate. This causes the pressure plate 303 to squeeze the airbag 307, causing the airbag 307 to contract under force. When the pressure plate 303 moves away from the airbag 307, the airbag 307 expands under the tension of the internal spring 308, allowing the airbag 307 to draw oil from the oil tank 310 into its interior through the connecting pipe 309. When the pressure plate 303 squeezes the airbag 307 again, the airbag 307 drips oil onto the chain 211 through the drip pipe 312, thus achieving the effect of lubricating the components of the device.
