Description

Technical Field

[0001] This utility model belongs to the technical field of desktop cold splicing machines, specifically relating to a desktop cold splicing machine with protective functions. Background Technology

[0002] A benchtop cold welding machine is a device that achieves metal joining through mechanical force, molecular force, or cold welding technology. It requires no heating or flux, has a compact structure, is easy to operate, and is suitable for small-batch or on-site operations. It is a highly efficient, environmentally friendly, and easy-to-operate welding device, especially suitable for joining non-ferrous metal wires and profiles. Its characteristic of requiring no power supply and flux makes it widely applicable in industrial manufacturing, electronics, jewelry, and other fields.

[0003] In some existing tabletop cold-welding machines, the drive handle is constantly exposed to the external environment during material installation. If accidentally touched by personnel, it can easily cause downward pressure, which can tighten the mold in the middle used for material connection, resulting in crushing and injury to the installer's fingers, which is quite inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a tabletop cold splicing machine with protective function. This solves the problem mentioned in the background art that some existing tabletop cold splicing machines have their drive handle constantly exposed to the external environment during the material installation process. If accidentally touched by personnel, it is very easy to generate downward pressure, which will cause the mold in the middle used for connecting materials to tighten, resulting in squeezing and injuring the installer's fingers, which is quite inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tabletop cold-welding machine with protective function, comprising a main body and a limiting mechanism disposed on one side of the main body to support and limit the handle in the non-use state, preventing pinching injury after accidental contact. The limiting mechanism includes sliding screws fixedly connected to one side of the top of the main frame and symmetrically arranged, a second spring movably connected to the outer side of the sliding screws, a limiting frame slidably connected to the outer side of the top of the sliding screws, a support plate fixedly connected to the top of the limiting frame, and a support plate fixedly installed on the top of the support plate. The device includes a buffer pad, a limiting pin slidably connected to the inner side of one end of the limiting frame, a main frame slidably connected to the outer side of one end of the limiting pin, a limiting ring fixedly connected to the outer side of the limiting pin, a side plate slidably connected to the outer side of the other end of the limiting pin, a first spring provided between the side plate and the limiting ring, a limiting pin movably connected to the inner side of the first spring, and a main frame fixedly connected to one side of the side plate. Before cold welding begins, the position of the rotating handle is limited by the limiting pin through the limiting frame support device, thereby reducing the risk of accidental contact causing it to press down.

[0006] Preferably, the main frame has symmetrically arranged foot pads at its bottom, two side clamps are fixedly installed on the outer side of the main frame, and the main frame has two main clamps fixedly installed on its top. An adjusting screw is threadedly connected to one side of the top of the main clamp. A forming mold is arranged on the inner side of the top of the main frame, and the forming mold is located between the main clamps. A rotating handle is drivenly connected to the bottom of the main clamp, and the main frame is rotatably connected to the outer side of one end of the rotating handle.

[0007] Preferably, a sliding rod is slidably connected to the other side inside the limiting frame, and two sliding rods are symmetrically arranged, with a foot pad fixedly connected to the bottom of the sliding rod.

[0008] Preferably, a nut is threaded onto the outer side of the bottom end of the sliding screw, and the nut is located below the second spring.

[0009] Preferably, a bracket is fixedly connected to one side of the bottom of the tray, and several brackets are symmetrically arranged. Each bracket has a hollow triangular structure, and a limit frame is fixedly connected to one side of the bracket.

[0010] Preferably, the buffer pad has an arc-shaped structure, the buffer pad is made of flexible material, and a support plate is fixedly connected to the bottom of the buffer pad.

[0011] Preferably, one end of the limiting pin is fixedly connected to a pinch button, and the pinch button is located on one side of the side plate.

[0012] Preferably, a limiting rod is fixedly connected to one side of the limiting ring, and two limiting rods are symmetrically arranged. A side plate is slidably connected to the outer side of the limiting rod.

[0013] Compared with the prior art, this utility model provides a tabletop cold welding machine with protective function, which has the following beneficial effects:

[0014] 1. This utility model improves the required force for lowering the limiting frame by setting a limiting frame and adjusting the force of the nuts pressing against the limiting frame by rotating the nuts on the outer side of the bottom end of the sliding screw according to the actual downward pressure required. Then, the material is clamped at both ends by the side clamps and the main clamps, so that it aligns with the inner side of the forming mold. After holding the outer wall of one end of the handle, the pinch button is squeezed, and the limiting pin is pulled on the inner side of the side plate, so that one end of the limiting pin successively disengages from the inner side of the main frame and the limiting frame, releasing the restriction on the position of the limiting frame. During the sliding of the limiting pin, the compression of the limiting ring causes the first spring to contract and store kinetic energy. The downward-pressing handle is used for cold connection. During the downward pressing of the handle, the pressure limit frame slides down on the outside of the sliding screw and compresses the second spring to store energy. After the cold connection is completed, the handle is released. At this time, the pressure on the second spring disappears, and it naturally extends to release kinetic energy. The upper limit frame is reset. The grip on the pinch button is released, so that the tension on the limit pin disappears. The first spring then opens and drives the limit pin to slide back to the position of re-inserting into the limit frame and the inner side of the main frame. The position of the limit frame is restricted, which can effectively prevent the handle of the device from being accidentally pressed down by external force during use, resulting in the crushing of the operator's palm.

[0015] 2. This utility model, by setting a pinch button, can effectively and conveniently allow personnel to directly pinch and pull the limiting pin to slide.

[0016] 3. By setting a nut and adjusting the force of the top of the nut pressing against the bottom of the limiting frame by rotating the nut, the elasticity of the second spring can be effectively improved.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: a tabletop cold-welding machine with protective function, including a main body 1 and a limiting mechanism 2 disposed on one side of the main body 1 to support and limit the handle in the non-use state, preventing pinching injury after accidental contact. The limiting mechanism 2 includes sliding screws 201 symmetrically arranged on one side of the top of the main frame 101, fixedly connected to the outer side of the sliding screws 201, a second spring 209 movably connected to the outer side of the top of the sliding screws 201, a limiting frame 202 slidably connected to the outer side of the top of the sliding screws 201, a support plate 203 fixedly connected to the top of the limiting frame 202, a buffer pad 204 fixedly installed on the top of the support plate 203, and a limit frame 202 at one end. A limiting pin 205 is slidably connected to the inner side. A main frame 101 is slidably connected to the outer side of one end of the limiting pin 205. A limiting ring 206 is fixedly connected to the outer side of the limiting pin 205. A side plate 208 is slidably connected to the outer side of the other end of the limiting pin 205. A first spring 207 is provided between the side plate 208 and the limiting ring 206. The limiting pin 205 is movably connected to the inner side of the first spring 207. The main frame 101 is fixedly connected to one side of the side plate 208. Before cold welding begins, the handle of the supporting device is limited by the limiting frame 202, which is restricted by the limiting pin 205, thus limiting the position of the handle and reducing the risk of accidental downward pressure. The force required for actual downward pressure is determined according to the actual downward pressure. To adjust the force of the top of the nut 4 pressing against the limiting frame 202, rotate each nut 4 on the outer side of the bottom end of the sliding screw 201 to improve the required force for the downward movement of the limiting frame 202. Then, clamp the material at both ends with the side clamp 103 and the main clamp 105, so that it aligns with the inner side of the forming mold 107. After holding the outer wall of one end of the handle 106, pinch the pinch button 6 and pull the limiting pin 205 on the inner side of the side plate 208. This causes one end of the limiting pin 205 to sequentially disengage from the inner side of the main frame 101 and the limiting frame 202, releasing the restriction on the position of the limiting frame 202. During the sliding of the limiting pin 205, the compression of the limiting ring 206 makes the first... A spring 207 contracts and stores kinetic energy, pressing down the handle 106 for cold connection. During the pressing down of the handle 106, the limiting frame 202 slides down outside the sliding screw 201, compressing the second spring 209 to store energy. After the cold connection is completed, the handle 106 is released. At this time, the pressure on the second spring 209 disappears, and it naturally extends to release kinetic energy, pushing the limiting frame 202 back to its original position. The grip on the pinch button 6 is released, causing the tension on the limiting pin 205 to disappear. The first spring 207 then opens, driving the limiting pin 205 to slide back to its original position and re-insert into the limiting frame 202 and the inner side of the main frame 101, thus restricting the position of the limiting frame 202.

[0026] In this utility model, preferably, foot pads 102 are symmetrically arranged at the bottom of the main frame 101, and two side clamps 103 are fixedly installed on the outside of the main frame 101. Two main clamps 105 are symmetrically arranged at the top of the main frame 101. An adjusting screw 104 is threadedly connected to one side of the top of the main clamp 105. A forming mold 107 is arranged on the inner side of the top of the main frame 101. The forming mold 107 is located between the main clamps 105. A handle 106 is drivenly connected to the bottom of the main clamp 105. The outer side of one end of the handle 106 is rotatably connected to the main frame 101. The materials at both ends are passed between the side clamps 103 and the main clamps 105 respectively, so that they are connected in the forming mold 107. Then, the handle 106 is held and pressed down, which drives the main clamp 105 to compress the first spring 207 and retract, thus completing the cold connection of the materials inside.

[0027] In this utility model, preferably, a sliding rod 3 is slidably connected to the other side inside the limiting frame 202. Two sliding rods 3 are symmetrically arranged, and a foot pad 102 is fixedly connected to the bottom of the sliding rod 3, which can effectively ensure the stability of the position of the limiting frame 202 during the lifting process.

[0028] In this utility model, preferably, a nut 4 is threadedly connected to the outer side of the bottom end of the sliding screw 201. The nut 4 is located below the second spring 209. By rotating the nut 4 to adjust the force of the top of the nut 4 pressing the bottom of the limiting frame 202, the elasticity of the second spring 209 can be effectively improved.

[0029] In this utility model, preferably, a bracket 5 is fixedly connected to one side of the bottom of the tray 203. Several brackets 5 are symmetrically arranged. Each bracket 5 has a hollow triangular structure. A limit frame 202 is fixedly connected to one side of the bracket 5, which can effectively expand the support area of ​​the tray 203 and reduce the degree of loosening.

[0030] In this utility model, preferably, the buffer pad 204 has an arc-shaped structure, the buffer pad 204 is made of flexible material, and the bottom of the buffer pad 204 is fixedly connected to the support plate 203, which can effectively reduce the wear on the surface of the handle 106 during the support process.

[0031] In this utility model, preferably, a pinch button 6 is fixedly connected to one end of the limiting pin 205. The pinch button 6 is located on one side of the side plate 208, which can effectively facilitate personnel to directly pinch and pull the limiting pin 205 to slide.

[0032] In this utility model, preferably, a limiting rod 7 is fixedly connected to one side of the limiting ring 206, and two limiting rods 7 are symmetrically arranged. A side plate 208 is slidably connected to the outer side of the limiting rod 7, which can effectively ensure the stability of the position of the limiting ring 206 during movement.

[0033] The working principle and usage process of this utility model are as follows: During use, based on the actual downward pressure required, rotate each nut 4 on the outer side of the bottom end of the sliding screw 201 to adjust the pressure of the top of the nut 4 against the limiting frame 202, thereby improving the required downward pressure on the limiting frame 202. Then, clamp the material at both ends with the side clamp 103 and the main clamp 105, making them align inside the forming mold 107. After holding the outer wall of one end of the handle 106, pinch the knob 6 to pull the limiting pin 205 inside the side plate 208, causing one end of the limiting pin 205 to sequentially disengage from the inner side of the main frame 101 and the limiting frame 202, releasing the restriction on the position of the limiting frame 202. During the sliding of the limiting pin 205, the compression of the limiting ring 206 causes the first spring 207 to contract. It stores kinetic energy and presses down the handle 106 for cold connection. During the pressing down of the handle 106, the limiting frame 202 slides down outside the sliding screw 201, and the second spring 209 is compressed to store energy. After the cold connection is completed, the handle 106 is released. At this time, the pressure on the second spring 209 disappears, and it naturally extends to release kinetic energy. The upper limiting frame 202 is reset. The grip on the pinch button 6 is released, so that the tension on the limiting pin 205 disappears. The first spring 207 then opens, driving the limiting pin 205 to slide back to the position of re-inserting into the limiting frame 202 and the inner side of the main frame 101. The position of the limiting frame 202 is restricted, which can effectively prevent the handle of the device from being accidentally pressed down by external force during use, resulting in the crushing of the operator's palm.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
