Description

Technical Field

[0001] This utility model relates to the field of hot wire clamp production technology, specifically a bending machine for hot wire clamp production. Background Technology

[0002] A hot wire clamp is a type of clamp used to hold an electric heating wire. It has high temperature resistance and sturdiness. Generally, during the production of hot wire clamps, a bending machine is needed to bend some curved shells or hot wire clamp components.

[0003] For example, the authorization announcement number "CN219985835U" is named a bending machine for pipe clamp production. In actual use, a certain space can be reserved for adaptive adjustment of the flat plate, and then the flat plate can be supported and limited to expand the application range of the bending machine and ensure the forming quality of the product. Existing bending machines basically need to rely on external mechanical force to directly press and bend the parts to be produced. This work and bending process cause a lot of heat to be generated in the metal parts and accumulate at the bending position. Therefore, the surface temperature of each part will be very high after bending. It is difficult for operators to quickly and manually remove the bent material. Directly touching the material with their hands can easily cause burns, which is very detrimental to the safety of using the bending machine. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing bending machines generate a lot of heat in the metal parts during the work and bending process, resulting in a high surface temperature of each production part after bending. This makes it difficult for operators to quickly and manually remove the bent material, and direct contact with the material can easily cause burns, which is detrimental to the safety of using the bending machine. Therefore, this invention proposes a bending machine for producing hot wire clamps.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a bending machine for hot wire clamp production, including a bending machine platform, pads and side plates. The side plates are fixedly installed on one side of the top of the bending machine platform, and multiple pads are fixedly connected to the bottom of the bending machine platform. A hot wire clamp bending part feeding and unloading structure is provided on one side of the upper part of the bending machine platform. A bending machine drive structure is provided on one side of the side plate, and a bending machine arc mold is provided on the other side of the top of the bending machine platform.

[0007] Preferably, the hot wire clamp bending part feeding and unloading structure includes a limiting plate and an arc-shaped unloading hole. The two limiting plates are fixedly connected to the top two sides of the bending machine platform. Multiple positioning shafts are rotatably connected inside the two limiting plates through pins. Openings are fixedly connected to the ends of the two limiting plates. Hot wire clamp processing parts are slidably connected to the inner side of the limiting plates. The arc-shaped unloading hole is fixedly opened at the top of the bending machine platform. A material receiving and cooling hopper is provided at the lower end of the arc-shaped unloading hole.

[0008] In this setup, the hot wire clamp workpiece is pushed and bent by the hydraulic cylinder above the arc-shaped feeding hole. It remains fixed due to the pushing force of the arc-shaped push plate and the arc-shaped mold plate. However, after the bending process is completed and the shape of the hot wire clamp workpiece is fixed, the hydraulic cylinder is activated in reverse. The hydraulic cylinder can pull the arc-shaped push plate away from the hot wire clamp workpiece. At this time, the bent part of the hot wire clamp workpiece, which has lost the pushing force, will fall down along the arc-shaped feeding hole below and fall directly into the prepared receiving and cooling hopper. There is no need for manual feeding and no need to contact the high-temperature workpiece.

[0009] Preferably, the bending machine drive structure includes a hydraulic cylinder and side blocks. The hydraulic cylinder is fixedly installed on the inner wall of the side plate. An arc-shaped push plate is fixedly installed at the front end of the hydraulic cylinder. Multiple side blocks are fixedly connected to the top two sides of the bending machine platform. Guide rods are fixedly connected inside two side blocks. Slider blocks are slidably connected to the outer sides of two guide rods. Connecting rods are fixedly connected to the outer sides of two sliders.

[0010] In this setup, the hydraulic cylinder is positioned using the rear side plate. The side block is vertically welded to the upper part of the bending machine platform. Inside the side block, there is a smooth horizontal guide rod. The slider can move laterally along the guide rod. After the hot wire clamp workpiece is placed in the corresponding position, the hydraulic cylinder can push the curved push plate at the front end forward. The curved push plate will press the hot wire clamp workpiece tightly against the outside of the curved mold plate. Through the continuous pushing pressure applied by the hydraulic cylinder, the hot wire clamp workpiece can be pushed and bent. During the movement of the curved push plate, the rear connecting rod can drive the slider to slide along the guide rod. In this way, the slider can limit the accuracy of the forward position of the curved push plate and avoid the push position deviation from affecting the bending effect.

[0011] Preferably, the other end of the two connecting rods is fixedly connected to the rear side of the arc-shaped push plate, and the front end of the arc-shaped push plate is movably connected to the hot wire clamp processing part.

[0012] Preferably, the curved mold of the bending machine includes a vertical plate and a support frame. The vertical plate is fixedly connected to the top of the bending machine platform on the other side. The support frame is fixedly connected to the side wall of the vertical plate, and the curved mold plate is fixedly connected to the other end of the support frame.

[0013] In this setup, the vertical plate is welded vertically to the other end of the bending machine platform. The vertical plate can support the front support frame and the arc-shaped mold plate. The arc-shaped mold plate is used to make hot wire clamp parts with arc bending, while the support frame provides vertical support to the arc-shaped mold plate, improving the pressure resistance of the arc-shaped mold plate.

[0014] Preferably, the front end of the arc-shaped mold plate is positioned opposite to the front end of the arc-shaped push plate, and the lower edge of the arc-shaped mold plate is positioned opposite to the top of the arc-shaped feeding hole.

[0015] The present invention discloses a bending machine for hot wire clip production, which has the following advantages: When the hot wire clip workpiece is pushed and squeezed by the hydraulic cylinder above the arc-shaped feeding hole, it will remain fixed due to the pushing force of the arc-shaped push plate and the arc-shaped mold plate. However, after the bending process is completed and the shape of the hot wire clip workpiece is fixed, the hydraulic cylinder is started in reverse. The hydraulic cylinder can pull the arc-shaped push plate away from the hot wire clip workpiece. At this time, the bent part of the hot wire clip workpiece, which has lost the pushing force, will fall along the arc-shaped feeding hole below and fall directly into the prepared receiving and cooling hopper. There is no need for manual feeding and no need to contact the high-temperature workpiece, thus improving the safety of the bending machine for hot wire clip production. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Please see Figure 1-6 In this embodiment, a bending machine for producing hot wire clips includes a bending machine platform 1, pads 2, and side plates 3. The side plates 3 are fixedly installed on one side of the top of the bending machine platform 1 and vertically welded to the top of the bending machine platform 1. The side plates 3 are used to support the pushing operation of the hydraulic cylinder 41. Multiple pads 2 are fixedly connected to the bottom of the bending machine platform 1. The pads 2 are vertical stainless steel columns used to support the upper bending machine platform 1. A hot wire clip bending part feeding and unloading structure 5 is provided on one side of the upper part of the bending machine platform 1. A bending machine drive structure 4 is provided on one side of the side plate 3. A bending machine arc mold 6 is provided on the other side of the top of the bending machine platform 1.

[0025] The hot wire clamp bending part feeding and unloading structure 5 includes a limiting plate 52 and an arc-shaped unloading hole 55. The two limiting plates 52 are fixedly connected to the top two sides of the bending machine platform 1. The limiting plates 52 are welded to the top edge of the bending machine platform 1. The slots on the inner sides of the two limiting plates 52 are set opposite to the top side of the arc-shaped unloading hole 55. Multiple positioning shafts 53 are rotatably connected to the inside of the two limiting plates 52 through pins. The ends of the two limiting plates 52 are fixedly connected to an opening 51, which is flared outwards. In this way, the strip-shaped hot wire clamp processing part 54 can be vertically inserted into the inner side of the two limiting plates 52. With manual pushing, it is placed horizontally above the arc-shaped unloading hole 55 for overlapping and waiting for extrusion and bending. The hot wire clamp processing part 54 is slidably connected to the inner side of the limiting plates 52. The hot wire clamp processing part 54 is a metal square strip material required for the production of hot wire clamps. During the bending process, the hot wire clamp part 54 is pushed and squeezed by the hydraulic cylinder 41 above the arc-shaped feeding hole 55. It will remain fixed due to the pushing force of the arc-shaped push plate 42 and the arc-shaped mold plate 63. However, after the bending process is completed and the shape of the hot wire clamp part 54 is fixed, the hydraulic cylinder 41 is started in reverse. The hydraulic cylinder 41 can pull back the arc-shaped push plate 42 away from the hot wire clamp part 54. At this time, the hot wire clamp part 54, which loses the pushing force, will fall along the arc-shaped feeding hole 55 below and fall directly into the prepared receiving and cooling hopper 56. The receiving and cooling hopper 56 is made of metal iron material and can receive the hot wire clamp part 54 with a relatively high temperature for a short time after bending. There is no need for manual feeding and no need to contact the high temperature processing part. The arc-shaped feeding hole 55 is fixedly opened at the top of the bending machine platform 1, and the receiving and cooling hopper 56 is provided at the lower end of the arc-shaped feeding hole 55.

[0026] The bending machine drive structure 4 includes a hydraulic cylinder 41 and side blocks 43. The hydraulic cylinder 41 is fixedly installed on the inner wall of the side plate 3. An arc-shaped push plate 42 is fixedly installed at the front end of the hydraulic cylinder 41. The hydraulic cylinder 41 is positioned by the rear side plate 3. Multiple side blocks 43 are fixedly connected to the top two sides of the bending machine platform 1. The side blocks 43 are vertically welded to the upper side of the bending machine platform 1. There are smooth horizontal guide rods 44 inside the side blocks 43. The sliders 45 can move laterally along the guide rods 44. The guide rods 44 are fixedly connected inside the two side blocks 43. The sliders 45 are slidably connected to the outer sides of the two guide rods 44. The connecting rods 46 are fixedly connected to the outer sides of the two sliders 45. The other ends of the two connecting rods 46 are connected to the arc-shaped push plate. The rear side of 42 is fixedly connected. After the hot wire clamp processing part 54 is placed in the corresponding position, the hydraulic cylinder 41 can push the front curved arc-shaped push plate 42 to move forward. The arc-shaped push plate 42 will press the hot wire clamp processing part 54 tightly against the outside of the arc-shaped mold plate 63. Through the continuous pushing pressure applied by the hydraulic cylinder 41, the hot wire clamp processing part 54 can be pushed and bent. During the movement of the arc-shaped push plate 42, the rear connecting rod 46 can drive the slider 45 to slide along the guide rod 44. In this way, the slider 45 can limit the accuracy of the forward position of the arc-shaped push plate 42 and avoid the pushing position deviation from affecting the bending effect. The front end of the arc-shaped push plate 42 is movably connected to the hot wire clamp processing part 54.

[0027] The curved die 6 of the bending machine includes a vertical plate 61 and a support frame 62. The vertical plate 61 is fixedly connected to the top of the bending machine platform 1 on the other side. The support frame 62 is fixedly connected to the side wall of the vertical plate 61. The vertical plate 61 is vertically welded to the other end of the bending machine platform 1. The vertical plate 61 can support the front support frame 62 and the curved die plate 63. The curved die plate 63 is used to make curved bending hot wire clamp parts. The support frame 62 provides vertical support for the curved die plate 63, improving the compressive strength of the curved die plate 63. The other end of the support frame 62 is fixedly connected to the curved die plate 63. The front end of the curved die plate 63 is opposite to the front end of the curved push plate 42. The lower edge of the curved die plate 63 is opposite to the top of the curved feeding hole 55.

[0028] Working principle:

[0029] The bending machine for hot wire clip production can be used to produce the bent parts of hot wire clips. The bending process of the parts is achieved by using a hydraulic cylinder to provide pushing and extruding force.

[0030] Side plate 3 is vertically welded to the top of bending machine platform 1. Side plate 3 is used to support the pushing work of hydraulic cylinder 41. Multiple pads 2 are fixedly connected to the bottom of bending machine platform 1. Pads 2 are vertical metal stainless steel columns used to support the upper bending machine platform 1.

[0031] The limiting plates 52 are welded to the top edge of the bending machine platform 1. The positioning shaft 53 can rotate to reduce friction and facilitate the sliding of the hot wire clamp processing part 54 inward. The ends of the two limiting plates 52 are fixedly connected to the openings 51, which are flared outward. In this way, the strip-shaped hot wire clamp processing part 54 can be vertically inserted into the inside of the two limiting plates 52. With manual pushing, it is placed horizontally above the arc-shaped feeding hole 55 and overlapped for extrusion and bending.

[0032] The hot wire clip processing part 54 is a metal square strip material required for the production of hot wire clips. When the hot wire clip processing part 54 is pushed and squeezed by the hydraulic cylinder 41 above the arc-shaped feeding hole 55, it will be fixed due to the pushing force of the arc-shaped pushing plate 42 and the arc-shaped mold plate 63. However, after the bending process is completed and the shape of the hot wire clip processing part 54 is fixed, the hydraulic cylinder 41 is started in the opposite direction. The hydraulic cylinder 41 can pull back the arc-shaped pushing plate 42 away from the hot wire clip processing part 54. At this time, the hot wire clip processing part 54, which loses the pushing force, will fall along the arc-shaped feeding hole 55 that has been pre-drilled below and fall directly into the prepared receiving and cooling hopper 56. The receiving and cooling hopper 56 is made of metal iron material and can bear the hot wire clip processing part 54 with a relatively high temperature for a short time after bending above. There is no need for manual feeding and no need to contact the high temperature processing part.

[0033] The hydraulic cylinder 41 is positioned by the rear side plate 3. The side block 43 is vertically welded to the upper part of the bending machine platform 1. The side block 43 has a smooth horizontal guide rod 44 inside. The slider 45 can move laterally along the guide rod 44. When the hot wire clamp processing part 54 is placed in the corresponding position, the hydraulic cylinder 41 can push the front curved arc push plate 42 forward. The arc push plate 42 will press the hot wire clamp processing part 54 tightly against the outside of the arc mold plate 63. Through the continuous pushing pressure applied by the hydraulic cylinder 41, the hot wire clamp processing part 54 can be pushed to produce bending. During the movement of the arc push plate 42, the rear connecting rod 46 can drive the slider 45 to slide along the guide rod 44. In this way, the slider 45 can limit the accuracy of the forward position of the arc push plate 42 and avoid the pushing position deviation from affecting the bending effect.

[0034] The vertical plate 61 is vertically welded to the other end of the bending machine platform 1. The vertical plate 61 can support the front support frame 62 and the arc-shaped mold plate 63. The arc-shaped mold plate 63 is used to make hot wire clamp parts with arc bending. The support frame 62 provides vertical support for the arc-shaped mold plate 63, improving the compressive strength of the arc-shaped mold plate 63.
